4 * Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
5 (XINERAMA_CFLAGS): New macros.
6 (ALL_CFLAGS, LIBES): Use them.
8 * xfns.c: Include <X11/extensions/Xrandr.h> if HAVE_XRANDR, and
9 include <X11/extensions/Xinerama.h> if HAVE_XINERAMA.
10 (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.
11 (syms_of_xfns): DEFSYM them.

16 (x_get_monitor_attributes_xinerama): New functions.
17 (Fx_display_monitor_attributes_list): New primitive.
18 (syms_of_xfns): Defsubr it.
20 * xterm.h (x_display_info): Add Xatom_net_workarea and
21 Xatom_net_current_desktop.
23 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
24 and dpyinfo->Xatom_net_current_desktop.
26 2013-05-06 Eli Zaretskii <eliz@gnu.org>
28 * xdisp.c (pos_visible_p): Use the special code for finding the
29 beginning of a display property or overlay for any "replacing"
30 display property, not just for display strings. This solves
31 incorrect reporting of position by posn-at-point. (Bug#14241)
33 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
35 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
36 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
37 Verify that ElfW (Half) fits in int.
38 (fatal): Use same signature as lisp.h.
39 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
40 configure and build with -DUNEXELF_DEBUG without worrying about
41 other modules that use DEBUG.
42 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
43 possibly-wide integers now uses it instead of plain fprintf.
44 (entry_address): New function, which avoids problems with 32-bit
45 overflow on 64-bit hosts.
46 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
47 (round_up): Don't assume the remainder fits in int.
48 (find_section): Use bool for boolean. Simplify debug code.
49 (unexec): Don't assume file sizes fit in int or size_t.
50 Omit unnecessary trailing newline in 'fatal' format.
51 Use strerror rather than outputting decimal error number.
52 Remove unused code when emacs is not defined;
53 this file relies on Emacs now.
54 Don't assume e_phnum and e_shnum are positive.
56 * regex.c: Fix problems when DEBUG is defined.
57 (extract_number, extract_number_and_incr): Define regardless of
58 whether DEBUG is defined; that's simpler and makes the code less
59 likely to go stale in the normal case when DEBUG is not defined.
60 Return int rather than taking an int * arg. All callers changed.
61 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
62 Remove, replacing with ...
63 (DEBUG_PRINT): New macro. All callers changed.
64 (DEBUG_COMPILES_ARGUMENTS): New macro.
65 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
66 (print_compiled_pattern, print_double_string) [DEBUG]:
67 Use prototype rather than old-style definition.
68 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
69 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
70 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
71 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
72 Don't assume ptrdiff_t, size_t, and long are the same width as int.
73 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
74 This matters only when DEBUG is defined.
76 2013-05-05 Eli Zaretskii <eliz@gnu.org>
78 * xdisp.c (set_iterator_to_next): Set the
79 ignore_overlay_strings_at_pos_p flag only if we are _really_
80 iterating over an overlay string, as indicated by the
81 current.overlay_string_index member. (Bug#14306)
83 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
85 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
86 to where it is used, to avoid autorelease issues (Bug#14050).
88 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
90 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
91 * fileio.c (syms_of_fileio): Implement this.
92 * filelock.c (create_lock_file): If symbolic links don't work, so
93 we use a regular file as a lock file, do not fsync the lock file;
96 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
98 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

106 w->contents is a buffer before computing everything else.
107 Use parentheses to disambiguate last part of the condition.
109 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
110 assertion violations. (Bug#14062)
112 2013-05-01 David Reitter <david.reitter@gmail.com>
114 * nsfns.m (ns_tooltip): Initialize.
116 2013-04-28 Eli Zaretskii <eliz@gnu.org>
118 * coding.c (decode_coding_gap): Don't remove the character before
119 a newline unless it's a CR character. (Bug#14287)
121 2013-04-28 Dan Nicolaescu <dann@gnu.org>
123 * dispextern.h (struct face): Move enum face_underline_type
124 earlier so that bitfields can be in the same word.
126 2013-04-28 Jan Djärv <jan.h.d@swipnet.se>
128 * nsfns.m (handlePanelKeys): New function.
129 (EmacsOpenPanel:performKeyEquivalent:)
130 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
131 arrows/function/control and copy/paste keys (Bug#14296).
133 2013-04-27 Juri Linkov <juri@jurta.org>
135 * callint.c (Fcall_interactively): Call `Qread_number' for
136 interactive code letter `n' instead of using duplicate code.
139 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
141 * systime.h (make_timeval): Declare as 'const'.
143 2013-04-27 Kenichi Handa <handa@gnu.org>
145 * font.c (font_open_entity): Always open a font of manageable
148 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
150 Port better to AIX (Bug#14258).
151 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
154 2013-04-24 Kenichi Handa <handa@gnu.org>
156 * coding.c (decode_coding_iso_2022): When an invalid escape
157 sequence is encountered, reset the invocation and designation
158 status to the safest one.
160 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
162 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
163 Without this fix, "make distclean" leaves stamp-h1 behind.
165 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
167 * w32fns.c (w32_fullscreen_rect): New function to compute the
168 window rectangle for the given fullscreen mode.
169 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
170 longer tunes the window size. This keeps the window's edges flush
171 with the screen and allows the taskbar to hide itself in fullboth.
173 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
174 window decorations and uses the entire screen.
176 * w32term.h (w32_fullscreen_rect) Add prototype.
177 (struct w32_output): Replace normal_width, normal_height,
178 normal_top, and normal_left members with a single normal_placement
180 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
182 (FRAME_NORMAL_PLACEMENT): New macro.
184 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
186 * minibuf.c (Ftest_completion): Silence compiler warning.
188 2013-04-15 Eli Zaretskii <eliz@gnu.org>
190 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
193 * frame.h (WINDOW_FRAME): Protect macro and its argument with
196 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
197 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
198 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
199 parentheses where appropriate.
201 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
203 * keyboard.c (timer_start_idle): Remove no-longer-used local.
205 2013-04-14 Eli Zaretskii <eliz@gnu.org>
207 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
208 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
209 Mention in the doc string that setting these variables takes
210 effect only after a call to set-window-buffer. (Bug#14200)
212 2013-04-13 Eli Zaretskii <eliz@gnu.org>
214 * indent.c (Fvertical_motion): Don't consider display strings on
215 overlay strings as display strings on the buffer position we
216 started from. This prevents vertical cursor motion from jumping
217 more than one line when there's an overlay string with a display
218 property at end of line.
219 Reported by Karl Chen <Karl.Chen@quarl.org> in
220 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
222 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
224 * window.c (select_window): `record_buffer' even if window is
225 already selected (bug#14191).
227 2013-04-11 Eli Zaretskii <eliz@gnu.org>
229 * window.c (Fwindow_end): Test more flags, including the buffer's
230 last_overlay_modified flag, to determine whether the window's
231 display is really up-to-date. Prevents the function from
232 returning a stale value. (Bug#14170)
233 (Fwindow_line_height): Fix the test for up-to-date-ness of the
236 2013-04-10 Eli Zaretskii <eliz@gnu.org>
238 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
239 garbaged only if it is not already the top frame on its TTY.
240 This prevents flickering due to constant redrawing of TTY frames when
241 there are GUI frames open in the same session. (Bug#13864)
243 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
245 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
246 of marking the idle timers directly.
248 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
250 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
253 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

268 (Fcopy_file, Fset_file_acl) [HAVE_POSIX_ACL]: Use it.
270 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
272 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
275 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
277 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
278 This bug was introduced by my 2013-02-25 change that simplified
279 data_start configuration. Without this change, on GNU/Linux
280 an Emacs configured with --enable-profiling fails immediately
281 due to a profiler signal.
282 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
283 with these flags. On platforms where special flags are needed
284 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
285 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
286 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
288 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>
290 Get rid of some platform-specific functions examining window
291 system and its capabilities. This is a partial rework of the
293 * lisp.h (have_menus_p): Remove prototype. This function is
294 replaced with platform-independent window_system_available.
295 (check_window_system): Move to...
296 * frame.h (decode_window_system_frame, window_system_available):
297 ...here, add new prototypes.

306 * msdos.c (have_menus_p): Remove.
307 * nsfns.m (check_window_system, have_menus_p, check_ns_frame):
308 Remove platform-specific functions. Use check_window_system,
309 decode_window_system_frame and check_ns_display_info where
310 appropriate. Minor style and comment tweaks.

325 changed. Check EOL format. Do not call adjust_coding_eol_type
327 (check_utf_8): New function.
328 (adjust_coding_eol_type): Do nothing if already adjusted.
329 (detect_coding): Compare the return value of check_ascii with
330 coding->src_bytes. Call adjust_coding_eol_type if necessary.
331 (decode_coding_gap): Optimize for valid UTF-8.
333 2013-03-21 Kenichi Handa <handa@gnu.org>
335 * coding.c (syms_of_coding): Cancel previous change.
337 * insdel.c (insert_from_gap): Fix previous change.
339 2013-04-05 Dmitry Antipov <dmantipov@yandex.ru>
341 Consistently use platform-specific function to detect window system.

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

388 * xsmfns.c (smc_save_yourself_CB):
389 Prefer < to > for range checks.
390 * dispnew.c (sit_for): Don't mishandle NaNs.
391 This fixes a bug introduced in the 2013-03-24 change.
392 * editfns.c (decode_time_components): Don't hoist comparison.
393 This fixes another bug introduced in the 2013-03-24 change.
395 2013-03-31 Dmitry Antipov <dmantipov@yandex.ru>
397 * frame.h (struct frame): Drop scroll_bottom_vpos
398 member becaue all real users are dead long ago.

404 * nsmenu.m (showAtX:Y:for:): setLevel to
405 NSPopUpMenuWindowLevel (Bug#13998).
407 2013-03-30 Jan Djärv <jan.h.d@swipnet.se>
409 * nsterm.h (ns_get_pending_menu_title, ns_check_menu_open)
410 (ns_check_pending_open_menu): Declare.
412 * nsmenu.m (ns_update_menubar): Correct NSTRACE.
413 (x_activate_menubar): Update the menu with title that matches
414 ns_get_pending_menu_title, and call
415 ns_check_pending_openmenu (Bug#12698).
416 (menuWillOpen:): New method.

447 2013-03-28 Dmitry Antipov <dmantipov@yandex.ru>
449 * window.h (struct window): Replace hchild, vchild and buffer slots
450 with the only contents slot. This is possible because each valid
451 window may have either the child window (in vertical or horizontal
452 combination) or buffer to display (for the leaf window). Using that,
453 a lof of operations to traverse and/or change window hierarchies may
454 be simplified. New member horizontal is used to distinguish between
455 horizontal and vertical combinations of internal windows.
456 (WINDOW_LEAF_P, WINDOW_HORIZONTAL_COMBINATION_P)

474 (mark_window_cursors_off, count_windows, get_leaf_windows)
475 (foreach_window_1): Simplify the loop.
476 * alloc.c (mark_object): Do not check for the leaf window because
477 internal windows has no glyph matrices anyway.

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

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

831 * coding.h (struct coding_system): New member eol_seen.
833 * coding.c (detect_ascii): New function.
834 (detect_coding): Set coding->head_ascii and coding->eol_seen only
835 when the source bytes are actually scanned. On detecting for
836 coding_category_utf_8_auto, call detect_ascii instead of scanning
837 source bytes directly.
838 (produce_chars): Call insert_from_gap with the new arg 0.
839 (encode_coding): Likewise.
840 (decode_coding_gap): Control ASCII optimization by the variable

873 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
874 too so that these builds can use Cygwin's file conversion
875 functions. (We've been building and linking cygw32.o all along
876 and just not using it.)
878 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

891 * w32term.c (w32_read_socket): If the Emacs frame is being
892 activated, call w32fullscreen_hook, to make sure the new frame
893 dimensions are in effect. (Bug#13937)
895 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
897 * xdisp.c (init_iterator): Simplify because both character and byte
898 positions are either specified or -1. Add eassert. Adjust comment.
899 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
900 character and byte positions can be obtained from marker.

920 Include <sys/param.h> unconditionally, as that works elsewhere and
921 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
922 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
925 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
927 * insdel.c (adjust_after_replace): Use bool for boolean.
929 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

957 can just use du like other systems.
959 * coding.c (from_unicode_buffer): Declare.
960 * coding.c (from_unicode_buffer): Implement.
962 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1009 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1010 from Elisp via unread-command-events.
1012 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1013 functions to mean "no change".

1023 (search_regs_saved, Fregexp_quote):
1024 Use bool for boolean.
1025 * region-cache.c (region_cache_forward, region_cache_backward):
1026 Fix comments to match code: these functions return int, not boolean.
1028 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1030 * search.c (find_newline): Accept start and end byte positions
1031 as arguments and allow -1 if not known.

1066 to match other functions accepting character and byte positions.
1068 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

1070 when you need just to move to the previous buffer position.
1071 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1073 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1149 * sysdep.c (list_system_processes)
1150 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1151 Make it a stub in this case; otherwise the build might fail,
1152 and this code hasn't been tested on such hosts anyway.
1153 Problem reported by Nelson H. F. Beebe in
1154 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1155 and analyzed by Jérémie Courrèges-Anglas in

1158 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1160 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1161 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1162 (get_visually_first_element, move_it_vertically_backward): Ajust users.

1166 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1168 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1169 * filelock.c: Include <c-ctype.h>.
1170 (MAX_LFINFO): New top-level constant.
1171 (lock_info_type): Remove members pid, boot_time. Add members at,
1172 dot, colon. Change user member to be the entire buffer, not a
1173 pointer. This allows us to handle the case where a foreign
1174 pid or boot time exceeds the local range. All uses changed.
1175 (LINKS_MIGHT_NOT_WORK): New constant.
1176 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1177 (defined_WINDOWSNT): Remove.
1178 (MAKE_LOCK_NAME, file_in_lock_file_name):
1179 Always use .#FILE (not .#-FILE) for the file lock,
1180 even if it is a regular file.
1181 (rename_lock_file): New function.
1182 (create_lock_file): Use it.
1183 (create_lock_file, read_lock_data):
1184 Prefer a symbolic link for the lock file, falling back on a
1185 regular file if symlinks don't work. Do not try to create
1186 symlinks on MS-Windows, due to security hassles. Stick with
1187 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1188 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1189 host may be using a Windowsish file system, and cannot use
1190 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1191 doesn't work. Don't fail merely because of a symlink-contents
1192 length limit in the current file system; fall back on regular
1193 files. Increase the symlink contents length limit to 8 KiB, this
1194 should be big enough for any real use and doesn't crunch the
1196 (create_lock_file, lock_file_1, read_lock_data):
1197 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1198 (lock_file_1): Return error number, not bool. All callers changed.
1199 (ELOOP): New macro, if not already defined.
1200 (read_lock_data): Return size of lock file contents, not Lisp object.
1201 All callers changed. Handle a race condition if some other process
1202 replaces a regular-file lock with a symlink lock or vice versa,
1203 while we're trying to read the lock.
1204 (current_lock_owner): Parse contents more carefully, to help avoid
1205 confusing a regular-file lock with some other application's use
1206 of the file. Check for lock file contents being too long, or
1207 not parsing correctly.
1208 (current_lock_owner, lock_file):
1209 Allow foreign pid and boot times that exceed the local range.
1210 (current_lock_owner, lock_if_free, lock_file):
1211 Simplify allocation of lock file contents.
1212 * w32.c (sys_rename_replace): New function, containing most of
1213 the contents of the old sys_rename.
1214 (sys_rename): Use it.
1215 (fchmod): New dummy function.
1216 * w32.h (sys_rename_replace, fchmod): New decls.
1218 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1220 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1221 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1222 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1223 <dmantipov@yandex.ru>.
1225 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1227 * composite.c (get_composition_id, fill_gstring_header):
1228 Use make_uninit_vector where appropriate.
1229 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1230 * xselect.c (clean_local_selection_data): Likewise.
1232 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1234 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1235 * image.c (imagemagick_load_image): Calculate height and width
1236 after flattening the image, not before.
1238 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1240 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1241 * ftfont.c (ftfont_shape_by_flt): Likewise.
1242 * w32uniscribe.c (uniscribe_shape): Likewise.
1244 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1246 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1247 The old approach, which fell back on DIR/.#FILE.0 through
1248 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1249 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1250 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1251 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1252 because the locking mechanism was never reliable in that case).
1253 This patch fixes this and other bugs discovered by a code
1254 inspection that was prompted by
1255 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1256 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1257 to avoid interoperability problems between the MS-Windows and
1258 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1259 instances of Emacs now ignore each others' locks.
1260 * filelock.c (defined_WINDOWSNT): New constant.
1261 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1262 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1263 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1264 regular files on MS-Windows hosts.
1265 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1266 Use SAFE_ALLOCA to avoid problems with long file names.
1267 (MAX_LFINFO): Now a local constant, not a global macro.
1268 (IS_LOCK_FILE): Remove.
1269 (lock_file_1): Don't inspect errno if symlink call succeeds;
1270 that's not portable.
1271 (lock_file): Document that this function can return if lock
1273 (lock_file): Don't access freed storage.
1275 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1279 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1281 * textprop.c: Use bool for booleans.
1282 (validate_interval_range, Fadd_text_properties)
1283 (Fremove_text_properties): Prefer bool to int when either works.
1285 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1287 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1288 If the interval tree changes as a side effect of calling
1289 modify_region, re-do processing starting from the call to
1290 validate_interval_range. (Bug#13743)
1292 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1294 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1297 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1299 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1300 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1301 access to the lock file until it is written and closed.
1304 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1306 * callint.c (Qcall_interactively):
1307 * macros.c (Qexecute_kbd_macro):

1316 Minor textprop integer cleanup.
1317 * intervals.h, textprop.c (add_text_properties_from_list):
1318 Return void, not int, since nobody uses the return value.
1319 * textprop.c (validate_plist, add_properties, remove_properties)
1320 (Fadd_text_properties):
1321 Don't assume list length fits in int.

1323 (interval_has_some_properties_list, add_properties, remove_properties)
1324 (Fadd_text_properties, Fremove_text_properties)
1325 (Fremove_list_of_text_properties, text_property_stickiness):
1326 Use bool for booleans.
1327 (Fadd_text_properties, Fremove_text_properties):
1328 (Fremove_list_of_text_properties):
1329 Reindent do-while as per GNU style.
1331 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1333 Implement CLASH_DETECTION for MS-Windows.
1335 * filelock.c [WINDOWSNT]: Include w32.h.
1336 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1337 function of that name. Up-case the macro arguments.
1338 (IS_LOCK_FILE): New macro.
1339 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1340 (create_lock_file): New function, with body extracted from
1342 [WINDOWSNT]: Implement lock files by writing a regular file with
1343 the lock information as its contents.
1344 (read_lock_data): New function, on Posix platforms just calls
1346 [WINDOWSNT]: Read the lock info from the file.
1347 (current_lock_owner): Call read_lock_data instead of calling
1348 emacs_readlinkat directly.
1349 (lock_file) [WINDOWSNT]: Run the file name through
1352 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1353 just check if the process by that PID exists.
1355 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1356 also present, as doing so will fail to error out if the file
1359 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1361 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1362 (Fremove_list_of_text_properties): Skip all of the intervals in
1363 the region between START and END that already have resp. don't
1364 have the requested properties, not just the first one.
1365 Add assertions that the loop afterwards always modifies the
1366 properties. (Bug#13743)
1368 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1370 * callint.c (Fcall_interactively): Use the right lexical environment

1379 (START_FILES): Remove. All uses removed.
1380 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.

1396 * vm-limit.c: Move most of mem-limits.h's contents here.
1397 (data_start): New decl. It's OK if this is approximate,
1398 so simplify-away some unnecessary exactness.
1399 (POINTER): Remove; all uses removed.
1400 (data_space_start): Now char *, to avoid casts.
1401 (exceeds_lisp_ptr): New function, replacing the old

1415 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
1416 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1417 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1418 and diagnosed by Andreas Schwab in
1419 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1421 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1423 Assume C89 or better.
1424 * ralloc.c (SIZE, POINTER, NIL):
1425 * vm-limit.c (POINTER):
1426 Remove, replacing all uses with C89 equivalents. These old
1427 symbols were present only for porting to pre-C89 platforms.
1429 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1431 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1432 This avoids warning messages reported as part of Bug#13546.
1434 2013-02-21 Ken Brown <kbrown@cornell.edu>
1436 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1438 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1440 * sheap.c (report_sheap_usage): Prefer message1_nolog.
1442 * keyboard.c (Qcommand_execute): New var.
1443 (command_loop_1, read_char): Use it.

1447 2013-02-19 Daniel Colascione <dancol@dancol.org>
1449 * sheap.c (report_sheap_usage): Use message, not message1, so
1450 that we don't try to create a buffer while we're in the middle
1451 of dumping Emacs. Explain why.
1453 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1455 * search.c (find_newline): Return byte position in bytepos.

1462 * editfns.c (Fconstrain_to_field, Fline_end_position):
1463 * indent.c (compute_motion, vmotion):
1464 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start):
1465 (get_visually_first_element, move_it_vertically_backward):
1466 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1468 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1470 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1471 resources were not orderly released.
1473 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1475 * xdisp.c (x_draw_vertical_border): For a window that is neither
1476 the leftmost nor the rightmost, redraw both the left and the right
1477 vertical borders. (Bug#13723)
1479 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
1481 * xml.c (init_libxml2_functions):

1488 * editfns.c (Fmessage, Fmessage_box):
1489 * callint.c (Fcall_interactively):
1490 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
1492 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
1494 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
1495 * frame.c (syms_of_frame): ... to here.
1497 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1499 * w32.c (sys_chown): Remove unused function.
1501 * w32term.c <input_signal_count>: Declare 'volatile'
1502 unconditionally. (Bug#9066)
1504 * w32.c (set_errno): Reset h_errno and don't set it to any other
1505 value. Set errno instead.
1506 (check_errno): Reset h_errno.
1507 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1508 (sys_gethostname, sys_getservbyname, sys_getpeername)
1509 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1510 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
1512 (sys_gethostbyname): Set h_errno only errors detected.
1514 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1516 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1518 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1520 * keyboard.c (read_char): Fix calculation of auto-save time out
1521 when auto-save-timeout is less than 4. (Bug#13720)
1523 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1524 time. Improve diagnostics in DebPrint. (Bug#13546)
1526 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
1527 (sys_gethostbyname, sys_getservbyname, sys_getpeername)

1529 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
1530 make sure errno is set to an appropriate value. (Bug#13546)
1531 (socket_to_fd): Add assertion against indexing fd_info[] with a
1532 value that is out of bounds.
1533 (sys_accept): If fd is negative, do not set up the child_process
1534 structure for reading.
1536 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1538 * composite.c (fill_gstring_header): Remove useless prototype.

1545 (get_overlay_arrow_glyph_row, display_mode_element):
1546 (decode_mode_spec_coding, message3):
1547 * xfaces.c (face_at_string_position): Use bool for booleans.
1550 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1552 Fix AIX port (Bug#13650).
1553 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1554 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1555 was #undeffed earlier, so it cannot be used as a macro here.
1556 Use the constant and not the macro.
1558 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1560 * w32proc.c (new_child): If no vacant slots are found in
1561 child_procs[], make another pass looking for slots whose process
1562 has exited or died. (Bug#13546)
1564 * w32.c (sys_pipe): When failing due to file descriptors above
1565 MAXDESC, set errno to EMFILE.
1566 (_sys_read_ahead): Update cp->status when failing to read serial
1567 communications input, so that the status doesn't stay at
1568 STATUS_READ_IN_PROGRESS. (Bug#13546)
1570 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1572 * gtkutil.c (tb_size_cb): New function.
1573 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1575 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1577 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1580 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1582 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1584 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1587 and break long line.
1588 * font.h (font_range): Adjust prototype.
1589 * composite.c (autocmp_chars): Pass byte position to font_range.
1590 Break long line. Remove useless prototype and format comment.
1592 2013-02-13 Glenn Morris <rgm@gnu.org>
1594 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1596 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1598 Improve AIX port some more (Bug#13650).
1599 With this, it should be as good as it was in 23.3, though it's
1600 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1601 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1602 * unexaix.c (start_of_text): Remove.
1603 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1604 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1605 (orig_load_scnptr, orig_data_scnptr):
1606 Now off_t, not long, since they are file offsets.
1607 (make_hdr): Use _data, not start_of_data ().
1608 This is the key part of the fix.
1609 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1610 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1612 * pre-crt0.c (data_start): Initialize to 1.
1613 This ports to compilers that optimize the external declaration
1614 'int x = 0;' as if it were 'int x;' to shrink the executable.
1616 Improve AIX port (Bug#13650).
1617 This doesn't fix the bug, but it makes progress: Emacs builds now.
1618 * unexaix.c: Include inttypes.h, stdarg.h.
1619 (report_error, report_error_1): Mark as _Noreturn.
1620 (report_error): Don't report the wrong errno.
1621 (report_error_1): Now varargs. All callers changed.
1622 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1623 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1624 (write_ptr): Use %p to print address rather than %lx and a cast
1625 to unsigned long. Grow buffer a bit, to be safer.
1627 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1629 * bidi.c (bidi_resolve_neutral): After finding the next
1630 non-neutral character, accept NEUTRAL_ON type as well, because
1631 directional control characters, such as LRE and RLE, have their
1632 type converted to that by bidi_resolve_weak. This avoids aborts
1633 when LRE/RLE follows a run of neutrals.
1634 (bidi_move_to_visually_next): Assert that return value of
1635 bidi_peek_at_next_level is non-negative. Negative values will
1638 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1640 Minor getenv-related fixes.
1641 * callproc.c (Fcall_process_region) [!DOS_NT]:
1642 Avoid unnecessary duplicate call to getenv.
1643 * callproc.c (init_callproc):
1644 * dispnew.c (init_display):
1645 * sysdep.c (sys_subshell):
1646 Omit unnecessary cast of getenv or egetenv.
1648 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1650 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1651 Update dependencies.
1653 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1655 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1657 (display_line): Set w->region_showing to the value of
1658 it->region_beg_charpos, not to -1. This fixes redisplay
1659 optimization when cursor is moved up after M->. (Bug#13623)
1661 (try_scrolling): Scroll text up more if point is too close to ZV
1662 and inside the scroll margin. This makes sure point is moved
1663 outside the scroll margin in these cases.
1665 * window.h (struct window): region_showing can no longer be
1668 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1670 Tune by using memchr and memrchr.
1671 * doc.c (Fsnarf_documentation):
1672 * fileio.c (Fsubstitute_in_file_name):
1673 * search.c (find_newline, scan_newline):
1674 * xdisp.c (pos_visible_p, display_count_lines):
1675 Use memchr and memrchr rather than scanning byte-by-byte.
1676 * search.c (find_newline): Rename from scan_buffer.
1677 Omit first arg TARGET, as it's always '\n'. All callers changed.
1679 Clean up read_key_sequence a tiny bit more.
1680 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1681 (read_key_sequence): Remove unused locals.
1683 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1685 Clean up read_key_sequence a bit; reread active keymaps after first event.
1686 * keyboard.c (read_char, read_char_x_menu_prompt)
1687 (read_char_minibuf_menu_prompt):
1688 Replace nmaps+maps with a single `map' arg.
1689 (follow_key): Operate on a single map.
1690 (active_maps): New function.
1691 (test_undefined): Also return true for nil bindings.
1692 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1693 a single (composed) keymap. Remember `first_event' to choose the right
1694 set of active keymaps. Recompute the set of keymaps after receiving
1695 the first event. Remove GOBBLE_FIRST_EVENT.
1696 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1697 * keyboard.h (read_char): Update declaration.
1698 * lread.c (read_filtered_event): Adjust call to read_char.
1700 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1702 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1703 Don't use the limitation on backwards movement when lines are truncated
1704 in the window. (Bug#13675)
1706 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1708 * marker.c (set_marker_internal): If desired position is passed
1709 as a marker, avoid call to buf_charpos_to_bytepos.
1710 * window.c (Fset_window_point): Omit redundant type checking.
1711 (Fset_window_start): Likewise. Format comment.
1712 (window_scroll_pixel_based): Use set_marker_restricted_both
1713 with character and byte positions obtained from an iterator.
1714 (Fset_window_configuration): Use set_marker_restricted_both.
1715 * xdisp.c (message_dolog): Likewise.
1717 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1719 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1720 When text lines are longer than window's screen lines, don't move back
1721 too far. This speeds up some redisplay operations. (Bug#13675)
1723 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1725 * syntax.c (scan_sexps_forward): Fix byte position calculation
1726 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1728 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1730 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1731 that was not needed.
1733 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1735 Minor hashing refactoring.
1736 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1737 (sxhash_float): Return EMACS_UINT, for consistency with the other
1739 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1740 non-static inline function and therefore can't use static vars.
1741 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1742 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1743 with the other hash functions.
1745 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1747 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1748 XXXXXX part of the temporary file pattern is not downcased even
1749 when w32-downcase-file-names is non-nil. (Bug#13661)
1751 * xdisp.c (decode_mode_spec): Remove handling of %t.
1753 * msdos.c (careadlinkatcwd): Remove.
1755 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1757 * lread.c (skip_dyn_bytes): New function (bug#12598).
1758 (read1): Use it. Use getc instead of READCHAR to read bytes.
1759 (load_each_byte): Remove. Update users.
1761 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1763 * search.c (scan_buffer): Calculate end byte position just once.

1766 * syntax.c (struct lisp_parse_state): New member location_byte.
1767 (scan_sexps_forward): Record from_byte and avoid redundant
1768 character to byte position calculation ...
1769 (Fparse_partial_sexp): ... here. Break too long line.
1771 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1773 * lisp.h (make_uninit_vector): New function.
1774 * alloc.c (Fvector, Fmake_byte_code):

1786 * window.c (Fcurrent_window_configuration):
1787 * xfaces.c (Fx_family_fonts):
1788 * xselect.c (selection_data_to_lisp_data): Use it.
1790 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1792 * coding.c (Fdefine_coding_system_internal): Use AREF where
1793 argument is known to be a vector.
1794 * fns.c (Flocale_info): Likewise for ASET.
1795 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1796 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1798 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1800 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1803 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1812 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1813 (check_native_fs): New function.
1814 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1815 (ns_term_init): Remove NEW_STYLE_FS.
1816 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1817 and tool bar if isFullscreen returns NO.
1818 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1819 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1820 with HAVE_NATIVE_FS.
1821 (window:willUseFullScreenPresentationOptions:): New method.
1822 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1823 Hide toolbar if not enabled (Bug#13444).
1824 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1825 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1826 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1827 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1828 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1829 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1830 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1831 (syms_of_nsterm): Add ns-use-native-fullscreen.
1833 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1835 * fileio.c (Qchoose_write_coding_system): Now static.
1837 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1839 * xdisp.c (window_buffer_changed): region_showing can be negative,
1840 which still means region is being displayed.
1841 (redisplay_internal): Resurrect code that forced redisplay of the
1842 whole window when showing region and the mark has changed.
1843 Record the new mark position to allow redisplay optimizations.
1844 (display_line): If it->region_beg_charpos is non-zero, set the
1845 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1847 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1848 not bitfield of 1 bit.
1850 2013-02-03 Daniel Colascione <dancol@dancol.org>
1852 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1853 daemon mode works on cygw32 when Emacs is installed and not just
1856 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1858 Avoid file time stamp bug on MS-Windows (Bug#13149).
1859 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1860 as FAT32 doesn't update time stamps when truncating them.
1861 Also, check that a file time stamp is not a multiple of 100 ns;
1862 this should catch all instances of the problem on MS-Windows,
1863 as its native file system resolution is 100 ns or worse, and
1864 checking for a non-multiple of 100 ns should impose only a small
1865 overhead on systems with ns resolution.
1867 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1869 Avoid encoding file names on MS-Windows when they need to be run
1870 through dostounix_filename.
1871 * w32.c (normalize_filename): Accept an additional argument
1872 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1873 downcase it even if w32-downcase-file-names is non-nil.
1874 (dostounix_filename): Accept an additional argument MULTIBYTE and
1875 pass it to normalize_filename.
1876 (emacs_root_dir): Adjust.
1878 * msdos.h (dostounix_filename): Adjust prototype.
1880 * w32.h (dostounix_filename): Adjust prototype.
1882 * msdos.c (dostounix_filename): Accept an additional argument and
1884 (init_environment): Adjust callers of dostounix_filename.
1886 * fileio.c (Ffile_name_directory, file_name_as_directory)
1887 (directory_file_name, Fexpand_file_name)
1888 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1890 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1892 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1893 variables, as egetenv is case-insensitive for DOS_NT.
1895 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1896 with an encoded file name.
1898 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1899 Adjust calls to dostounix_filename.
1901 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1903 * unexw32.c (unexec): Adjust call to dostounix_filename.
1905 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1907 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1910 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1913 * callproc.c (Fcall_process): Make sure program name in PATH and
1914 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1915 is passed to exec/spawnve, which fails unless the file-name
1918 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1919 even if w32-quote-process-args is nil.
1921 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1923 Fix timestamp bug when write-region appends nothing (Bug#13149).
1924 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1925 the file's time stamp doesn't change if Emacs happens to write nothing
1926 to the file, and on a buggy file system this could cause Emacs to
1927 incorrectly infer that the file system doesn't have the bug.
1928 Avoid this problem by inhibiting the inference in this case.
1930 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1932 * window.h (struct window): Convert base_line_number, base_line_pos
1933 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1934 Convert region_showing member from Lisp_Object to bitfield.
1935 Remove sequence_number member. Adjust comments.
1936 * window.c (sequence_number): Remove.
1937 (make_window): Initialize column_number_displayed.
1938 * print.c (print_object): Follow the printed representation of
1939 frames and print window pointer to distinguish between windows.
1940 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1941 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1942 (wset_column_number_displayed, wset_region_showing): Remove.
1943 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1944 (try_scrolling, try_cursor_movement, redisplay_window)
1945 (try_window_reusing_current_matrix, try_window_id, display_line)
1946 (display_mode_lines, decode_mode_spec): Adjust users.
1947 * .gdbinit (pwinx): Do not print sequence_number.
1949 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1951 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1952 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1953 * dired.c: Include <fcntl.h>.
1954 (open_directory): New function, which uses open and fdopendir
1955 rather than opendir. DOS_NT platforms still use opendir, though.
1956 (directory_files_internal, file_name_completion): Use it.
1957 (file_attributes): New function, with most of the old Ffile_attributes.
1958 (directory_files_internal, Ffile_attributes): Use it.
1959 (file_attributes, file_name_completion_stat): First arg is now fd,
1960 not dir name. All uses changed. Use fstatat rather than lstat +
1962 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1963 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1964 (emacs_readlinkat): New function, with much of the old
1965 Ffile_symlink_p, but with an fd argument for speed.
1966 It uses readlinkat rather than careadlinkatcwd, so that it
1967 need not assume the working directory.
1968 (Ffile_symlink_p): Use it.
1969 * filelock.c (current_lock_owner): Use emacs_readlinkat
1970 rather than emacs_readlink.
1971 * lisp.h (emacs_readlinkat): New decl.
1972 (READLINK_BUFSIZE, emacs_readlink): Remove.
1973 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1974 (emacs_norealloc_allocator, emacs_readlink): Remove.
1975 This stuff is moved to fileio.c.
1976 * w32.c (fstatat, readlinkat): New functions.
1977 (careadlinkat): Don't check that fd == AT_FDCWD.
1978 (careadlinkatcwd): Remove; no longer needed.
1980 2013-01-31 Glenn Morris <rgm@gnu.org>
1982 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1983 (Fwrite_region): Update for new choose_write_coding_system args.
1984 Move the last piece of choose_write_coding_system here. (Bug#13522)
1985 (syms_of_fileio): Add choose-write-coding-system.
1987 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1989 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1990 (sys_close): Zero out the flags for the file descriptor before
1991 closing it. (Bug#13546)
1993 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1994 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1995 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1998 * w32.c (w32_get_long_filename, init_environment, readlink):
1999 Support file names encoded in DBCS codepages.
2000 (readlink): Use the current file-name-coding-system, not the ANSI
2001 codepage, to decode and handle targets of symlinks.
2003 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2005 * w32.c (opendir): Now accepts a 'const char *'.
2007 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2009 Remove obsolete redisplay code. See the discussion at
2010 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2011 * dispnew.c (preemption_period, preemption_next_check): Remove.
2012 (Vredisplay_preemption_period): Likewise.
2013 (update_frame, update_single_window, update_window, update_frame_1):
2014 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2015 used, following the 2012-06-22 change.
2017 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2019 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2021 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2023 * font.c (num_fonts): Remove the leftover from old
2024 debugging code. Adjust comment style here and there.
2025 * insdel.c (insert_1): Remove.
2026 * lisp.h (insert_1): Remove prototype.
2027 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2029 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2031 * w32.c (max_filename_mbslen): New function.
2032 (normalize_filename, readdir): Use it to detect locales where ANSI
2033 encoding of file names uses a double-byte character set (DBCS).
2034 If a DBCS encoding is used, advance by characters using
2035 CharNextExA, instead of incrementing a 'char *' pointer.
2036 Use _mbslwr instead of _strlwr. (Bug#13515)
2038 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2039 request of memory reservation to 1.7GB. (Bug#13065)
2041 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2043 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2044 at check_extra_latin label. (Bug#13505)
2046 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2048 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2049 Avoid redundant calls to strlen.
2051 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2053 Drop async_visible and async_iconified fields of struct frame.
2054 This is possible because async input is gone; for details, see
2055 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2056 * frame.h (struct frame): Remove async_visible and async_iconified
2057 members, convert garbaged to unsigned bitfield. Adjust comments.
2058 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2059 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2060 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2061 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2062 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2064 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2065 properly. Likewise for obscured.
2067 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2070 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2072 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2074 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2075 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2077 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2079 * xdisp.c (message2, message2_nolog): Remove functions.
2080 (message3, message3_nolog): Extract nbytes and multibyteness directly
2081 from the string. Change all callers.
2082 (message3_nolog): Don't set message_enable_multibyte since set_message
2083 will reset it anyway.
2084 (message1, message1_nolog): Use message3.
2085 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2086 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2087 (set_message): Drop all but the second arg, which has to be a string.
2088 (set_message_1): Simplify now that we know that a1 is NULL and the
2089 second arg is a string.
2090 * frame.h (struct frame): Remove `message_buf' field.
2091 Use glyphs_initialized_p instead.
2092 (FRAME_MESSAGE_BUF): Remove macro.
2093 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2094 * lisp.h (message2, message2_nolog): Remove declarations.
2095 (message3, message3_nolog): Update declarations.
2096 * keyboard.c (read_char_minibuf_menu_text)
2097 (read_char_minibuf_menu_width): Remove vars.
2098 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2099 to correctly handle multibyte strings.
2100 * frame.c (delete_frame): Don't free message_buf any more.
2101 * editfns.c (message_text, message_length): Remove vars.
2102 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2103 * fileio.c (auto_save_error): Use message3 instead of message2.
2104 * dispnew.c (adjust_frame_message_buffer): Remove function.
2106 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2108 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2109 real estate used for the tool bar and the menu bar.
2111 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2113 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2114 hidden buffer is prepared to modification (Bug#13164).
2116 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2118 * window.h (struct window): Change window_end_valid member from
2119 Lisp_Object to a bitfield. Adjust comments.
2120 (wset_window_end_valid): Remove.
2121 * window.c (adjust_window_count): Clear window_end_valid.
2122 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2123 (Fwindow_line_height, set_window_buffer, Frecenter)
2124 (Fsplit_window_internal, Fdelete_other_windows_internal)
2125 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2126 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2127 * xdisp.c (check_window_end, reconsider_clip_changes)
2128 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2129 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2130 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2132 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2134 * xdisp.c (mark_window_display_accurate): Simplify the loop
2135 assuming that the only one of vchild, hchild or buffer window
2136 slots is non-nil. Call mark_window_display_accurate_1 for
2137 the leaf windows only.
2138 (mark_window_display_accurate_1): Always assume leaf window.
2141 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2143 * emacs.c (Qkill_emacs_hook): Now static.
2145 * fileio.c (Finsert_file_contents): Simplify.
2146 Remove unnecessary assignments and tests.
2148 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2150 * w32.c (acl_set_file): Don't test for errors unless
2151 set_file_security returns FALSE. Avoids spurious errors when
2154 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2156 * fileio.c (Finsert_file_contents): Revert code introduced at
2157 2013-01-18 in favor of the simpler and generally better fix.
2158 Save stack space by removing 'buffer' and reusing 'read_buf'
2161 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2163 * lisp.h (eabs): Define unconditionally (Bug#13419).
2164 The old "#if !defined (eabs)" was an unnecessary revenant of back
2165 when this macro was called "abs". Document 'eabs' better.
2167 2013-01-19 Glenn Morris <rgm@gnu.org>
2169 * fns.c (Frandom): Doc fix.
2171 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2173 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2174 segfault when there are lots of overlays.
2176 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2177 when there are lots of overlays.
2178 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2179 for the details and a way to reproduce.
2181 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2183 * fileio.c: Use O_APPEND to append.
2184 This corresponds better to the natural interpretation of "append",
2185 and avoids the need to open the output file twice, or to invoke
2186 lseek when APPEND is neither nil nor a number.
2187 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2188 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2189 file possibly twice, and lseeking to its end; this avoids the
2190 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2191 at the same time: the combination is never needed and apparently
2192 it doesn't work with DOS_NT.
2194 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2195 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2197 Allow floating-point file offsets.
2198 Problem reported by Vitalie Spinu in
2199 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2200 * fileio.c (emacs_lseek): Remove.
2201 (file_offset): New function.
2202 (Finsert_file_contents, Fwrite_region): Use it.
2204 2013-01-19 Chong Yidong <cyd@gnu.org>
2206 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2207 aborting on Fsignal (Bug#13289).
2209 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2211 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2212 set_file_security as failure due to insufficient privileges.
2213 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2214 (fstat): Return owner and group like 'stat' and 'lstat' do.
2216 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2218 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2219 The bug was observed on Ubuntu operating inside a virtual machine,
2220 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2221 The workaround introduces a race condition on non-buggy hosts,
2222 but it's an unlikely race and anyway there's a nearly identical
2223 nearby race that can't be fixed.
2224 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2226 (Fwrite_region): Test for file system time stamp bug.
2227 (init_fileio): New function.
2228 * lisp.h (init_fileio): Declare it.
2229 * emacs.c (main): Call it.
2231 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2232 and make it more consistent with other stat-failure diagnostics.
2234 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2236 Fix crash when inserting data from non-regular files.
2237 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2238 for the error description produced by valgrind.
2239 * fileio.c (read_non_regular): Rename to read_contents.
2240 Free Lisp_Save_Value object used to pass parameters.
2241 (read_non_regular_quit): Rename to read_contents_quit.
2242 (Finsert_file_contents): Redesign internal file reading loop to adjust
2243 gap and end positions after each read and so help make_gap to work
2244 properly. Do not signal an I/O error too early and so do not leave
2245 not yet decoded characters in a buffer, which was the reason of
2246 redisplay crash. Use list2 to build return value. Adjust comments.
2248 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2250 Close a race when statting and reading files (Bug#13149).
2251 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2252 This avoids a race if the file is renamed between stat and open.
2253 This race is not the problem originally noted in Bug#13149;
2254 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2256 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2258 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
2259 objects, related functions and macros.
2260 (make_save_value): Adjust prototype.
2261 (make_save_pointer): New prototype.
2262 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2263 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2264 * alloc.c (format_save_value): Rename to make_save_value.
2265 (make_save_pointer): New function.
2266 (record_xmalloc): Use make_save_pointer.
2267 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2268 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2269 Change users of make_save_value to make_save_pointer.
2270 Likewise for format_save_value and make_save_value.
2272 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2274 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
2275 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
2276 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
2279 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2281 * alloc.c (free_save_value): Now static.
2283 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2285 * keymap.c (map_keymap_internal): Use format_save_value.
2286 (map_keymap_char_table_item): Adjust accordingly.
2287 * fileio.c (non_regular_fd, non_regular_inserted)
2288 (non_regular_nbytes): Remove.
2289 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2290 Use format_save_value to pass parameters to read_non_regular.
2291 (read_non_regular): Use XSAVE_ macros to extract parameters.
2293 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2295 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2297 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2299 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2300 extraction from any Lisp_Save_Value slot. Add type checking.
2301 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2302 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2303 * xselect.c: All users changed.
2305 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2307 Some convenient bits to deal with Lisp_Save_Values.
2308 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
2309 (allocate_misc): Remove prototype.
2310 (format_save_value): New prototype.
2311 * alloc.c (allocate_misc): Revert back to static.
2312 (format_save_value): New function to build Lisp_Save_Value

2353 * editfns.c (save_excursion_save): Pack everything within
2354 Lisp_Save_Value and so avoid xmalloc.
2355 (save_excursion_restore): Adjust to match new layout. Use free_misc
2356 because we do not allocate extra memory any more. Add eassert.
2357 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2358 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2359 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2360 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2370 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2372 Fix SIGDANGER handlers, for AIX (Bug#13408).
2373 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2374 Move handlers here from emacs.c; they were out of place.
2376 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2378 * xterm.c (syms_of_xterm): Adjust documentation for

2426 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2428 Avoid unnecessary byte position calculation for the gap movement.
2429 Since all users of move_gap do CHAR_TO_BYTE for other purposes

2440 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2442 * term.c (init_tty): Use them instead of rolling our own code.
2443 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2444 switches from 'signal' to 'pthread_sigmask', which is safer in
2445 multithreaded applications.
2446 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2447 which has already arranged for that.
2448 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2449 This is the main part of the bug fix.

2461 predicate, which is how it's really used now. Adjust comment.
2462 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2463 * buffer.c (buffer_slot_type_mismatch): Remove.
2464 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
2465 predicate. Adjust comment.

2467 fill-column, left-margin, tab-width, buffer-saved-size,
2468 left-margin-width, right-margin-width, left-fringe-width,
2469 right-fringe-width, scroll-bar-width and buffer-display-count.
2470 Use Qstringp for default-directory, buffer-file-name,
2471 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2472 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2474 * data.c (store_symval_forwarding): Adjust to call the predicate.

2490 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2491 (make_gap_1): New function to adjust the gap of any buffer.
2492 * coding.c (coding_alloc_by_making_gap): Use it.
2493 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2494 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

2517 trailing dash is properly added.
2519 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2521 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2522 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2523 digits for buffer positions, before misalignment starts.
2524 Display "0" for integer "object" field.
2525 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2526 Display the newline glyph more unambiguously.
2528 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2530 * nsterm.m (ns_draw_underwave):
2531 * w32term.c (w32_draw_underwave):
2532 * xterm.c (x_draw_underwave): Make underwave look more triangular
2533 and also degrade gracefully for small fonts. (Bug#13000)
2535 * nsterm.m (ns_draw_text_decoration):
2536 * w32term.c (x_draw_glyph_string):
2537 * xterm.c (x_draw_glyph_string): Don't use previous underline
2538 thickness and position if previous underline type is underwave.
2540 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2542 * fileio.c (Ffile_acl): Undocument return format.
2544 2013-01-02 Glenn Morris <rgm@gnu.org>
2546 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2558 * term.c (tty_ins_del_lines):
2559 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2560 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2562 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2564 * w32.c (unsetenv): Set up the string passed to _putenv
2566 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2567 for the bug this caused.
2569 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2571 * coding.c (Qmac): Now static.
2573 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2575 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2576 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2580 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2581 Show all on TOOLBAR_TOP_WIDGET.
2582 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2583 by TOOLBAR_TOP_WIDGET.
2584 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2585 Check toolbar_is_packed.
2586 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2587 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2588 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2590 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2591 (xg_update_menubar): Update title only if
2592 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2593 (xg_update_submenu): Skip tearoff only if
2594 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2595 (xg_initialize): Initialize xg_detached_menus only if
2596 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2598 * xterm.h (struct x_output): Surround handlebox_widget with
2599 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2600 toolbar_in_hbox is bool.
2602 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2604 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2605 (LIBS_GNUSTEP): Define.
2606 (LIBES): Add $(LIBS_GNUSTEP).
2607 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2609 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2611 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2612 continuation glyph on a TTY with an indication of an empty line.
2615 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2617 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2618 file's SELinux context or ACLs successfully set, nil otherwise.
2620 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2622 * w32proc.c (reader_thread): Avoid passing NULL handles to
2623 SetEvent and WaitForSingleObject.
2625 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2627 Port EXTERNALLY_VISIBLE to Clang 3.2.
2628 * conf_post.h (__has_attribute): New macro.
2629 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2631 2012-12-27 Glenn Morris <rgm@gnu.org>
2633 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2634 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2636 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2638 * fileio.c (file_name_as_directory, directory_file_name):
2639 Accept an additional argument MULTIBYTE to indicate whether the input C
2640 came from a multibyte or a unibyte Lisp string; all callers
2641 adjusted. Don't assume the input string is always multibyte.
2643 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2644 don't ENCODE_FILE them, and return a unibyte string if the input
2646 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2647 don't assume the input strings will always be multibyte. If the
2648 input strings are multibyte, decode strings obtained from C
2651 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2653 * lisp.h (toplevel): Add two notices to the comment about
2654 defining a new Lisp data type.
2655 * print.c (print_object): If Lisp_Save_Value object's pointer

2658 * alloc.c (valid_lisp_object_p): Adjust comment.
2660 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2662 * keyboard.c (record_asynch_buffer_change): Initialize an event
2663 only if it's really needed.
2664 * frame.h (enum output_method): Remove output_mac member since
2665 it's a leftover from the deleted code.
2666 * frame.c (Fframep): Adjust user here ...
2667 * terminal.c (Fterminal_live_p): ... and here.
2668 * coding.c (Qmac): Now here because it's only used to denote
2669 end-of-line encoding type.
2670 (syms_of_coding): DEFSYM it.
2671 * frame.h (Qmac): Remove duplicated declaration.
2673 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2675 * window.c (select_window_1): Now static, since it's used only here.
2677 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2679 * window.c (window_body_cols): Subtract display margins from the
2680 window body width on TTYs as well. See
2681 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2682 for the original report.
2684 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2686 * xdisp.c (redisplay_window): Remove inner local variable
2687 because the outer shadowed one has the same meaning.
2688 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2690 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2691 (xg_create_tool_bar): Adjust users.
2693 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2695 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2696 * buffer.c (Fget_buffer_create): Use it to set compact field of
2697 struct buffer_text to avoid accessing an uninitialized value
2698 when compact_buffer is called for the first time.
2699 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2700 (Fset_buffer_modified_p): Use buffer_window_count to check
2701 whether the buffer is displayed in some window.
2702 * xdisp.c (message_dolog): Likewise.
2704 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2706 * w32.c (acl_set_file): If setting the file security descriptor
2707 fails, and the new DACL is identical to the existing one, silently
2708 return success. This fixes problems for users backing up their
2709 own files without having the necessary privileges for setting
2710 security descriptors.
2712 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2714 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2715 after WaitForSingleObject returns normally. This expedites reader
2716 thread shutdown when delete_child triggers it.
2717 (reap_subprocess): More accurate commentary for why we call
2718 delete_child only when cp->fd is negative.
2720 * w32.c (sys_close): Do not call delete_child on a subprocess
2721 whose handle is not yet closed. Instead, set its file descriptor
2722 to a negative value, so that reap_subprocess will call
2723 delete_child on that subprocess when its SIGCHLD arrives.
2724 This avoids closing handles used for communications between sys_select
2725 and reader_thread, which doesn't give sys_select a chance to
2726 notice that the process exited and invoke the SIGCHLD handler for
2729 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2731 * nsfns.m (Fns_do_applescript): Run event loop until script has
2732 been executed (Bug#12969).
2733 (ns_run_ascript): Chech as_script for nil, set to nil after
2736 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2738 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2740 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2742 * w32term.c (w32fullscreen_hook): New function.
2743 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2745 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2747 * fileio.c (Finsert_file_contents): Doc fix.
2749 * w32proc.c (new_child, delete_child, find_child_pid): For a
2750 subprocess, consider its slot being in use as long as its process
2751 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2752 slot when a new process is started immediately after killing
2753 another one, without waiting enough time for the first process to
2754 be reaped and resources allocated for it be orderly freed.
2756 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2758 2012-12-21 Chong Yidong <cyd@gnu.org>
2760 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2762 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2764 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2766 * w32.c (get_name_and_id): Always pass NULL as the first argument
2767 of lookup_account_sid. Avoids crashes with UNC file names that
2768 refer to DFS domains, not to specific machine names. (Bug#12621)
2769 Remove now unused argument FNAME; all callers changed.
2770 (get_file_owner_and_group): Remove now unused argument FNAME; all
2773 2012-12-21 Chong Yidong <cyd@gnu.org>
2775 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2776 error for invalid chars, don't check for a nil return value.
2778 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2780 Avoid calls to CHAR_TO_BYTE if byte position is known.
2781 * editfns.c (make_buffer_string_both): Use move_gap_both.
2782 (Fbuffer_string): Use make_buffer_string_both.
2783 * marker.c (buf_charpos_to_bytepos): Convert to eassert.

2864 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2866 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2867 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2868 for some of that bug's symptoms can now cause Emacs to abort.
2869 Remove the workaround.
2870 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2871 The bug that caused SIGCHLD to get lost has been fixed, and the

2919 asynchronous subprocess, record the name of the input file name,
2921 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2922 delete the file, record it as pending deletion when the subprocess
2925 2012-12-14 Eli Zaretskii <eliz@gnu.org>

2952 * dired.c (Ffile_attributes) [WINDOWSNT]:
2953 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2954 owner and group information from 'lstat'.
2956 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2958 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2959 as that confuses set-auto-coding, so insist on the head-read

2988 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2990 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2991 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2992 Remove unnecessary S_ISLNK test, as (contra the comments) this
2993 function can't copy symlinks. Improve quality of error message
2994 when attempting to copy files that are neither regular files nor

3013 * inotify.c (inotify_callback): Generate an Emacs event for every
3014 incoming inotify event.
3016 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3018 * xdisp.c (handle_face_prop): Fix logic of computing
3019 it->start_of_box_run_p.
3020 (append_space_for_newline): If the glyph row is R2L, reset the
3021 iterator's end_of_box_run_p flag before prepending the space glyph.

3023 iterator's start_of_box_run_p flag before prepending the stretch.

3265 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3266 Remove USG and vlimit methods; no longer used these days.
3267 Add #error catchall just in case.
3269 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3270 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3271 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3272 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3273 (deleted_pid_list, Fdelete_process, create_process)
3274 (record_child_status_change, handle_child_signal, deliver_child_signal)
3275 (init_process_emacs, syms_of_process):
3276 Assume SIGCHLD is defined.
3277 (parse_signal): Remove. All uses removed.
3278 (abbr_to_signal): New static function.
3279 (Fsignal_process): Use it to convert signal names to ints.
3280 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3281 kill (getpgrp (), ...).
3282 (emacs_sigaction_init): Assume SIGCHLD is defined.
3283 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3284 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
3285 * syssignal.h (EMACS_KILLPG): Remove.
3286 All uses replaced by 'kill' with a negative pid.
3287 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3288 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3290 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3292 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3293 This will cause a production Emacs to dump core instead of
3296 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3298 * frame.c (make_frame): Do not set window's buffer to t.
3299 * window.c (Fsplit_window_internal): Likewise. Previously it was
3300 used to indicate that the window is being set up. Now we use
3301 set_window_buffer for all new windows, so the condition in ...
3302 (Fset_window_buffer): ... is always true and can be removed.
3304 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3306 Convenient macro to check whether the buffer is hidden.
3307 * buffer.h (BUFFER_HIDDEN_P): New macro.
3308 * frame.c (make_frame): Use it. Adjust comment.
3309 * buffer.c (candidate_buffer): New function.
3310 (Fother_buffer, other_buffer_safely): Use it.
3312 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3314 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3315 if the child process is still running. Instead, exit the wait
3316 loop and return zero. (Bug#13086)
3318 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3320 * frame.h (x_char_width, x_char_height): Remove prototypes.
3321 * w32term.h (x_char_width, x_char_height): Likewise.
3322 * xfns.c (x_char_width, x_char_height): Remove.
3323 * w32fns.c (x_char_width, x_char_height): Likewise.
3324 * nsfns.c (x_char_width, x_char_height): Likewise.
3325 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
3327 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
3328 * keyboard.c (command_loop_1): Remove prototype.
3329 (command_loop_2, top_level_1): Add static to match prototype.
3331 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3333 Fix a recently-introduced delete-process race condition.
3334 * callproc.c, process.h (record_kill_process):
3335 New function, containing part of the old call_process_kill.
3336 (call_process_kill): Use it.
3337 This does not change call_process_kill's behavior.
3338 * process.c (Fdelete_process): Use record_kill_process to fix a
3339 race condition that could cause Emacs to lose track of a child.
3341 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3343 Avoid code duplication between prev_frame and next_frame.
3344 * frame.c (candidate_frame): New function. Add comment.
3345 (prev_frame, next_frame): Use it. Adjust comment.
3347 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3349 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3350 fails, signal an error instead of continuing with an empty
3352 Encode expanded temp file pattern before passing it to mkstemp or
3355 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3356 Encode the file name before passing it to dostounix_filename, in
3357 case it will downcase it (under w32-downcase-file-names).
3360 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3362 Minor call-process cleanups.
3363 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3364 at the same time as other platforms, to simplify analysis.
3365 No need for fd0_volatile since we have synch_process_fd.
3366 Avoid needless emacs_close; arg is always negative.
3368 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3370 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3373 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3375 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3376 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3377 and mouse_face_hidden members to a bitfields.
3378 * frame.h (struct frame): Remove set-but-not-used space_width member.
3379 (FRAME_SPACE_WIDTH): Remove.
3380 * nsterm.m, w32term.c, xterm.c: Adjust users.
3381 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3382 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3383 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3384 members to a bitfields.
3386 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3388 Don't let call-process be a zombie factory (Bug#12980).
3389 Fixing this bug required some cleanup of the signal-handling code.
3390 As a side effect, this change also fixes a longstanding rare race
3391 condition whereby Emacs could mistakenly kill unrelated processes,
3392 and it fixes a bug where a second C-g does not kill a recalcitrant
3393 synchronous process in GNU/Linux and similar platforms.
3394 The patch should also fix the last vestiges of Bug#9488,
3395 a bug which has mostly been fixed on the trunk by other changes.
3396 * callproc.c, process.h (synch_process_alive, synch_process_death)
3397 (synch_process_termsig, sync_process_retcode):
3398 Remove. All uses removed, to simplify analysis and so that
3399 less consing is done inside critical sections.
3400 * callproc.c (call_process_exited): Remove. All uses replaced
3401 with !synch_process_pid.
3402 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3403 These take the role of what used to be in unwind-protect arg.
3405 (block_child_signal, unblock_child_signal):
3406 New functions, to avoid races that could kill innocent-victim processes.
3407 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3408 (call_process_kill): Record killed processes as deleted, so that
3409 zombies do not clutter up the system. Do this inside a critical
3410 section, to avoid a race that would allow the clutter.
3411 (call_process_cleanup): Fix code so that the second C-g works again
3412 on common platforms such as GNU/Linux.
3413 (Fcall_process): Create the child process in a critical section,
3414 to fix a race condition. If creating an asynchronous process,
3415 record it as deleted so that zombies do not clutter up the system.
3416 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3417 light of these changes. Omit unnecessary call to emacs_close
3418 before failure, as the unwind-protect code does that.
3419 * callproc.c (call_process_cleanup):
3420 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3421 * process.c (record_deleted_pid): New function, containing
3422 code refactored out of Fdelete_process.
3423 (Fdelete_process): Use it.
3424 (process_status_retrieved): Remove. All callers changed to use
3425 child_status_change.
3426 (record_child_status_change): Remove, folding its contents into ...
3427 (handle_child_signal): ... this signal handler. Now, this
3428 function is purely a handler for SIGCHLD, and is not called after
3429 a synchronous waitpid returns; the synchronous code is moved to
3430 wait_for_termination. There is no need to worry about reaping
3431 more than one child now.
3432 * sysdep.c (get_child_status, child_status_changed): New functions.
3433 (wait_for_termination): Now takes int * status and bool
3434 interruptible arguments, too. Do not record child status change;
3435 that's now the caller's responsibility. All callers changed.
3436 Reimplement in terms of get_child_status.
3437 (wait_for_termination_1, interruptible_wait_for_termination):
3438 Remove. All callers changed to use wait_for_termination.
3439 * syswait.h: Include <stdbool.h>, for bool.
3440 (record_child_status_change, interruptible_wait_for_termination):
3442 (record_deleted_pid, child_status_changed): New decls.
3443 (wait_for_termination): Adjust to API changes noted above.
3445 * bytecode.c, lisp.h (Qbytecode): Remove.
3446 No longer needed after 2012-11-20 interactive-p changes.
3448 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3450 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3451 the scroll margin, move point outside the margin. (Bug#13055)
3453 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3455 * gtkutil.c (my_log_handler): New function.
3456 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3458 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3460 * lisp.h (modify_region): Rename to...
3461 (modify_region_1): ...new prototype.
3462 * textprop.c (modify_region): Now static. Adjust users.
3463 * insdel.c (modify_region): Rename to...
3464 (modify_region_1): ...new function to work with current buffer.
3465 Adjust comment and users. Use true and false for booleans.
3467 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3469 * alloc.c (free_save_value): New function.
3470 (safe_alloca_unwind): Use it.
3471 * lisp.h (free_save_value): New prototype.
3472 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3474 (save_excursion_restore): Adjust to match saved data structure.
3475 Use free_save_value to offload some work from GC. Drop obsolete
3478 2012-12-03 Chong Yidong <cyd@gnu.org>
3480 * fileio.c (Vauto_save_list_file_name): Doc fix.
3482 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3484 * w32fns.c: Remove prototype of atof.
3485 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3487 (file_dialog_callback): Make it UINT_PTR.
3489 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3492 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3493 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3496 2012-12-03 Glenn Morris <rgm@gnu.org>
3498 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3500 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3502 Fix xpalloc confusion after memory is exhausted.
3503 * alloc.c (xpalloc): Comment fix.
3504 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3505 and signals an error, do not clear charset_table_size, as
3506 charset_table is still valid.
3507 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3509 Use execve to avoid need to munge environ (Bug#13054).
3510 * callproc.c (Fcall_process):
3511 * process.c (create_process):
3512 Don't save and restore environ; no longer needed.
3513 * callproc.c (child_setup):
3514 Use execve, not execvp, to preserve environ.
3516 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3518 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3520 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3522 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3523 display for sliced images (Bug#10500).
3525 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3527 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3529 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3530 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3532 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3534 * xdisp.c (window_outdated): Remove eassert since it hits
3535 some suspicious corner cases (see Bug#13007 and Bug#13012).
3536 (mode_line_update_needed): New function.
3537 (redisplay_internal, redisplay_window): Use it.
3538 (ensure_selected_frame): New function.
3539 (redisplay_internal, unwind_redisplay): Use it.
3540 (redisplay_internal): Move comment about buffer_shared...
3541 (buffer_shared_and_changed): ...near to its real use.
3543 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3545 * callproc.c (Fcall_process): Don't misreport vfork failure.
3547 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3549 * callproc.c (Fcall_process): Fix vfork portability problems.
3550 Do not assume that fd[0], count, filefd, and save_environ survive
3551 vfork. Fix bug whereby wrong errno value could be reported for
3552 pipe failure. Some minor cleanups, too, as follows. Move buf and
3553 bufsize to the context where they're needed. Change new_argv to
3554 be of type char **, as this is more convenient and avoids casts.
3555 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3556 Now local constants, not macros.
3558 2012-11-18 Kenichi Handa <handa@gnu.org>
3560 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3561 for the variable "f".
3563 2012-11-13 Kenichi Handa <handa@gnu.org>
3565 * font.c (font_unparse_xlfd): Exclude special characters from the
3566 generating XLFD name.
3568 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3570 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3582 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3583 Assume EIO and EAGAIN are defined.
3584 * unexcoff.c (write_segment): Assume EFAULT is defined.
3586 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3588 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3591 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3592 highlighting on the frame was cleared. Prevents assertion
3593 violations when repeatedly clicking on the "Top" link of the
3594 "bread-crumbs" in Info buffers.

3603 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3604 were always defined.
3606 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3608 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3609 between bpos_covered and bpos_max. This fixes cursor display when
3610 several display strings follow each other.
3612 * .gdbinit (pgx): If the glyph's object is a string, display the
3613 pointer to string data, rather than the value of the string object
3614 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3616 * indent.c (Fvertical_motion): If the starting position is covered
3617 by a display string, return to one position before that, to avoid
3618 overshooting it inside move_it_to. (Bug#12930)
3620 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3622 * frame.h (struct frame): Remove display_preempted member

3627 (set_frame_menubar): Adjust user.
3628 * w32term.h (struct x_output): Drop outdated #if 0 code.
3629 (struct w32_output): Use bitfields for explicit_parent,
3630 asked_for_visible and menubar_active members.
3631 Drop unused pending_menu_activation member.
3632 * xterm.h (struct x_output): Drop outdated #if 0 code.
3633 Use bitfields for explicit_parent, asked_for_visible,
3634 has_been_visible and net_wm_state_hidden_seen members.

3638 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3639 of a literal "/". (Bug#12955)
3640 (gl-stamp): Invoke fc.exe directly, not through cmd.
3642 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

3645 * dired.c: Assume HAVE_DIRENT_H.
3646 (NAMLEN): Remove, replacing with ...
3647 (dirent_namelen): New function. All uses changed. Use the GNU macro
3648 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3649 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3650 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3651 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3653 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3654 * ndir.h: Rename to ../nt/inc/dirent.h.
3655 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3656 Do not include <dirent.h>; no longer needed.
3657 * w32.c: Include <dirent.h> rather than "ndir.h".
3659 2012-11-23 Chong Yidong <cyd@gnu.org>
3661 * xftfont.c (xftfont_open): Remove duplicate assignment.
3663 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3665 * alloc.c (Fgarbage_collect): Unblock input after clearing
3666 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3667 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3668 * msdos.c (IT_frame_up_to_date): Use it here...
3669 * w32term.c (w32_frame_up_to_date): ...here...
3670 * xterm.c (XTframe_up_to_date): ...and here...
3671 * nsterm.m (ns_frame_up_to_date): ...but not here.
3672 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3674 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3675 Do not check whether GC is in progress.
3677 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3679 * xdisp.c (window_buffer_changed): New function.
3680 (update_menu_bar, update_tool_bar): Use it to
3681 simplify large 'if' statements.
3682 (redisplay_internal): Generalize commonly used
3683 'tail' and 'frame' local variables.
3685 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3687 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3688 with Windows system header.
3690 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3692 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3693 * alloc.c: Assume unistd.h exists.

3697 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3698 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3699 * w32.h (getcwd): Remove decl.
3701 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

3709 * emacs.c (main): Set the G_SLICE environment variable for all
3710 Cygwin builds, not just GTK builds. See
3711 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3713 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3715 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3716 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3717 Define for the MSVC compiler.
3719 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3721 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3722 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3723 dostounix_filename. Prevents crashes down the road, because
3724 dostounix_filename assumes it gets a unibyte string.
3725 Reported by Michel de Ruiter <michel@sentient.nl>, see

3732 * lread.c (init_obarray): Set `function' fields to Qnil.
3733 * eval.c (Fcommandp): Ignore Qunbound.
3734 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3735 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3736 Test NILP rather than Qunbound.
3737 (Ffmakunbound): Set to Qnil.
3738 (Fsymbol_function): Never signal an error.
3739 (Finteractive_form): Ignore Qunbound.
3741 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3743 * eval.c (interactive_p): Remove no-longer-used decl.
3745 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3747 * xdisp.c (buffer_shared): Adjust comment.
3748 (buffer_shared_and_changed): New function.
3749 (prepare_menu_bars, redisplay_internal): Use it to
3750 decide whether all windows or frames should be updated.
3751 (window_outdated): New function.
3752 (text_outside_line_unchanged_p, redisplay_window): Use it.
3753 (redisplay_internal): Likewise. Fix indentation.
3755 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3757 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3758 (syms_of_eval): Remove corresponding defsubr.
3759 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3761 2012-11-19 Daniel Colascione <dancol@dancol.org>
3763 * w32fns.c (Fx_file_dialog):
3764 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3765 cygwin_convert_file_name*.
3767 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3768 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3770 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3772 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3774 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3776 * w32select.c: Include w32common.h before w32term.h, so that
3777 windows.h gets included before w32term.h uses some of its
3778 features, see below.
3780 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3782 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3784 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3786 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3788 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3789 (ns_select): Return at once if events are held (Bug#12834).
3791 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3793 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3794 Needed following 2012-10-20 change. (Bug#12902)
3796 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3798 * w32proc.c (waitpid): Remove unused label get_result.
3800 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3802 * makefile.w32-in (SYSWAIT_H): New macro.
3803 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3804 ($(BLD)/sysdep.$(O)): Update dependencies.
3806 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3808 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3809 * callproc.c (relocate_fd): Assume F_DUPFD.
3810 * emacs.c, term.c (O_RDWR): Remove.
3811 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3812 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3813 * nsterm.m: Assume <fcntl.h> exists.
3814 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3815 (create_pty, Fmake_network_process, server_accept_connection)
3816 (wait_reading_process_output, init_process_emacs):
3818 (wait_reading_process_output): Put in a special case for WINDOWSNT
3819 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3820 It's not clear this is needed, but it's a more-conservative change.
3821 (create_process): Assume FD_CLOEXEC.
3822 (create_process, create_pty): Assume O_NOCTTY.
3823 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3824 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3825 Omit if not DOS_NT, since F_GETFL is not defined there.
3826 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3827 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3829 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3830 lack it, since gnulib guarantees this.
3831 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3833 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3835 * w32.c (faccessat): Pretend that directories have the execute bit
3836 set. Emacs expects that, e.g., in files.el:cd-absolute.
3838 * w32proc.c (create_child): Don't clip the PID of the child
3839 process to fit into an Emacs integer, as this is no longer a
3841 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3842 reaping only the process specified by PID argument, if that is
3843 positive. Use PID instead of dead_child to know which process to
3844 reap. Wait for the child to die only if WNOHANG is not in
3846 (sys_select): Don't set dead_child.
3848 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3849 as it is no longer needed.
3851 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3853 (record_child_status_change): Remove the setting of
3854 record_at_most_one_child for the !WNOHANG case.
3856 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3858 Fix problems in ns port found by static checking.
3859 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3860 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3861 not to process group.
3862 (ns_select): Use emacs_write, not write, as that's more robust
3863 in the presence of signals.
3864 (fd_handler:): Check for read errors.
3866 2012-11-16 Glenn Morris <rgm@gnu.org>
3868 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3870 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3872 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3874 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3876 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3877 use the same value of thread handle.
3878 (start_timer_thread): If the timer thread exited (due to error),
3879 clean up by closing the two handles it used. Duplicate the caller
3880 thread's handle here, so it gets duplicated only once, when
3881 launching the timer thread. Set priority of the timer thread, not
3883 (getitimer): Don't duplicate the caller thread's handle here.
3886 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3888 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3891 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3893 Remove no-longer-used pty_max_bytes variable.
3894 * process.c (pty_max_bytes): Remove; unused.
3895 (send_process): Do not set it.
3897 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3899 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3900 Update dependencies.
3902 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3904 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3905 This follows up on the 2012-09-29 patch that removed indirection
3906 for the 'function' field. Reported by Sergey Vinokurov in
3907 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3909 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3911 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3912 different name, as the MS runtime does not have such a function,
3913 and probably never will.) All callers changed. Ignore DIRFD
3914 value if PATH is an absolute file name, to match Posix spec
3915 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3918 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3920 * xdisp.c (echo_area_display, redisplay_internal):
3921 Omit redundant check whether frame_garbaged is set.
3923 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3925 Use faccessat, not access, when checking file permissions (Bug#12632).
3926 This fixes a bug that has been present in Emacs since its creation.
3927 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3928 which must set some sort of record. (Torek's bug report was against
3929 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3930 same common flaw.) See Torek's Usenet posting
3931 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3932 Posted: Fri Apr 8 14:18:56 1983.
3933 * Makefile.in (LIB_EACCESS): New macro.
3935 * callproc.c (init_callproc):
3936 * charset.c (init_charset):
3937 * fileio.c (check_existing, check_executable, check_writable)
3939 * lread.c (openp, load_path_check):
3940 * process.c (allocate_pty):
3942 Use effective UID when checking permissions, not real UID.
3943 * callproc.c (init_callproc):
3944 * charset.c (init_charset):
3945 * lread.c (load_path_check, init_lread):
3946 Test whether directories are accessible, not merely whether they exist.
3947 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3948 * fileio.c (check_existing, check_executable, check_writable)
3950 Use symbolic names instead of integers for the flags, as they're
3952 (check_writable): New arg AMODE. All uses changed.
3953 Set errno on failure.
3954 (Ffile_readable_p): Use faccessat, not stat + open + close.
3955 (Ffile_writable_p): No need to call check_existing + check_writable.
3956 Just call check_writable and then look at errno. This saves a syscall.
3957 dir should never be nil; replace an unnecessary runtime check
3958 with an eassert. When checking the parent directory of a nonexistent
3959 file, check that the directory is searchable as well as writable, as
3960 we can't create files in unsearchable directories.
3961 (file_directory_p): New function, which uses 'stat' on most platforms
3962 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3963 (Ffile_directory_p, Fset_file_times): Use it.
3964 (file_accessible_directory_p): New function, which uses a single
3965 syscall for efficiency.
3966 (Ffile_accessible_directory_p): Use it.
3967 * xrdb.c (file_p): Use file_directory_p.
3968 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3969 * lread.c (openp): When opening a file, use fstat rather than
3970 stat, as that avoids a permissions race. When not opening a file,
3971 use file_directory_p rather than stat.
3972 (dir_warning): First arg is now a usage string, not a format.
3973 Use errno. All uses changed.
3974 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3975 that merely introduced a race.
3976 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3977 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3978 and similarly for the other O_* flags.
3979 * w32.c (sys_faccessat): Rename from sys_access and switch to
3980 faccessat's API. All uses changed.
3981 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3982 (magic_db): Rename from magic_file_p.
3983 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3984 char *, so that we don't have to test for file existence
3985 separately from opening the file for reading. This removes a race
3986 fixes a permission-checking problem, and simplifies the code.
3988 (file_p): Remove; no longer needed.
3990 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3992 Omit glyphs initialization at startup.
3993 * dispnew.c (glyphs_initialized_initially_p): Remove.
3994 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3995 (Fredraw_frame): Move actual code from here...
3996 (redraw_frame): ...to here. Add eassert. Adjust comment.
3997 (Fredraw_display): Use redraw_frame.
3998 * xdisp.c (clear_garbaged_frames): Likewise.
4000 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4002 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4003 passed to pint2str and pint2hrstr to be at most the size of the
4004 frame's decode_mode_spec_buffer. This avoids crashes with very
4005 large values of FIELD_WIDTH argument to decode_mode_spec.
4008 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4010 Fix a race with verify-visited-file-modtime (Bug#12863).
4011 Since at least 1991 Emacs has ignored an mtime difference of no
4012 more than one second, but my guess is that this was to work around
4013 file system bugs that were fixed long ago. Since the race is
4014 causing problems now, let's remove that code.
4015 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4016 whose time stamp is off by no more than a second. Insist that the
4017 file time stamps match exactly.
4019 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4021 * frame.h (struct frame): Convert external_tool_bar member to
4022 1-bit unsigned bitfield.
4023 * termhooks.h (struct terminal): Remove mouse_moved member since
4024 all users are long dead. Adjust comment on mouse_position_hook.
4026 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4028 Simplify by using FOR_EACH_FRAME here and there.
4029 * frame.c (next_frame, prev_frame, other_visible_frames)
4030 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4031 * w32term.c (x_window_to_scroll_bar): Likewise.
4032 * window.c (window_list): Likewise.
4033 * xdisp.c (x_consider_frame_title): Likewise.
4034 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4035 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4036 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4037 * xmenu.c (menubar_id_to_frame): Likewise.
4038 * xselect.c (frame_for_x_selection): Likewise.
4039 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4040 (x_window_to_menu_bar): Likewise.
4041 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4043 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4045 * data.c (Qdefalias_fset_function): Now static.
4047 Another tweak to vectorlike_header change.
4048 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4049 Remove, and replace all uses with ...
4050 (next_in_free_list, set_next_in_free_list):
4051 New functions, which respect C's aliasing rules better.
4053 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4055 * window.c (list4i): Rename from 'quad'. All uses changed.
4056 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4058 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4060 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4061 warning about mixing declarations and code in ISO C90.
4063 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4065 * window.c (Fsplit_window_internal): Set combination limit of
4066 new parent window to t iff Vwindow_combination_limit is t;
4067 fixing a regression introduced with the change from 2012-09-22.
4068 (Fset_window_combination_limit): Fix doc-string.
4070 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4072 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4073 amount when the scroll margins are too large. When scrolling
4074 backwards in the buffer, give up if cannot reach point or the
4075 scroll margin within a reasonable number of screen lines.
4076 Fixes point position in window under scroll-up/down-aggressively when
4077 point is positioned many lines beyond the window top/bottom.
4080 * ralloc.c (relinquish): If real_morecore fails to return memory
4081 to the system, don't crash; instead, leave the last heap
4082 unchanged and return. (Bug#12774)
4084 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4086 * lisp.h (AUTOLOADP): New macro.
4087 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4088 * data.c (Ffset): Remove special ad-advice-info handling.
4089 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4091 (Finteractive_form): Simplify.
4092 (Fquo): Don't insist on having at least 2 arguments.
4093 (Qdefalias_fset_function): New var.
4095 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4097 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4099 * nsfont.m (Qcondensed, Qexpanded): New variables.
4100 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4101 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4103 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4105 Fix recently introduced crash on MS-Windows (Bug#12839).
4106 * w32term.h (struct scroll_bar): Use convenient header.
4107 (SCROLL_BAR_VEC_SIZE): Remove.
4108 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4110 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4112 Tweak last vectorlike_header change.
4113 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4114 vectorlike object on the free list. This is introduced to avoid
4115 some (but not all) pointer casting and aliasing problems, see
4116 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4117 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4119 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4121 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4123 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4124 been removed, so remove them here also.
4126 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4128 * doc.c (Fdocumentation): Handle new property
4129 dynamic-docstring-function to replace the old ad-advice-info.
4131 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4133 * fns.c (Qeql, hashtest_eq): Now static.
4135 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4137 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4138 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4139 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4140 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4142 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4144 Use same hash function for hashfn_profiler as for hash_string etc.
4145 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4146 * lisp.h (sxhash_combine): New inline function, with the contents
4147 of the old SXHASH_COMBINE.
4148 * profiler.c (hashfn_profiler): Use it, instead of having a
4149 special hash function containing a comparison that always yields 1.
4151 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4153 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4154 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4155 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4158 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4160 * image.c (xpm_make_color_table_h): Fix compiler error because
4161 make_hash_table changed.
4163 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4165 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4167 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4169 Use ad-hoc comparison function for the profiler's hash-tables.
4170 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4171 (make_log): Use them.
4172 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4173 call Fequal any more.
4174 (Ffunction_equal): New function.
4175 (cmpfn_profiler, hashfn_profiler): New functions.
4176 (syms_of_profiler): Initialize them.

4182 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4183 (hash_lookup, hash_remove_from_table): Move assertion checking of
4184 hashfn result here. Check hash-equality before calling cmpfn.
4185 (Fmake_hash_table): Adjust call to make_hash_table.
4186 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
4187 (syms_of_fns): Initialize them.

4192 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
4194 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4196 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4197 value of w32-scroll-lock-modifier is neither nil nor one of the
4198 known key modifiers. (Bug#12806)
4200 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4202 Shrink struct vectorlike_header to the only size field.
4203 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4205 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4206 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4207 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4208 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4209 information from the vector header. Adjust comment.

4219 (enum mem_type): Adjust comment.
4220 (NEXT_IN_FREE_LIST): New macro.
4221 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4222 (Fmake_bool_vector): Likewise.
4223 (struct large_vector): New type to represent allocation unit for
4224 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4225 (large_vectors): Change type to struct large_vector.
4226 (allocate_vector_from_block): Simplify.
4227 (PSEUDOVECTOR_NBYTES): Replace with...
4228 (vector_nbytes): ...new function. Adjust users.
4229 (sweep_vectors): Adjust processing of large vectors.
4230 (allocate_vectorlike): Likewise.
4231 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4232 Add easserts. Adjust XSETPVECTYPESIZE usage.
4233 (allocate_buffer): Use BUFFER_PVEC_INIT.
4234 (live_vector_p): Adjust to match large vector.
4235 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4236 * buffer.h (struct buffer): Add next member.
4237 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4239 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4240 * fns.c (internal_equal): Adjust to match enum pvec_type change.

4245 (xvecsize): New command.
4247 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4249 * keyboard.c (event_to_kboard): Do not dereference
4250 frame_or_window field of SELECTION_REQUEST_EVENT
4251 and SELECTION_CLEAR_EVENT events (Bug#12814).
4252 * xterm.h (struct selection_input_event): Adjust comment.
4254 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4256 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4257 such as Scroll Lock, if the respective keys are treated as
4258 function keys, not as modifiers. This avoids destroying non-ASCII
4259 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4261 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4263 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4265 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4267 Restore some duplicate definitions (Bug#12814).
4268 This undoes part of the 2012-11-03 changes. Some people build
4269 with plain -g rather than with -g3, and they need the duplicate
4270 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4271 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4272 Define as macros, as well as as enums or as constants.
4274 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4276 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4277 to keypad keys (Bug#12816).
4279 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4281 Minor adjustments of recently-changed frame functions.
4282 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4283 known to be a frame (we're in the FRAMEP branch).
4284 * lisp.h (Qframep): Remove decl. frame.h declares this.
4285 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4286 since they're meant for Lisp fixnum values.
4288 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4290 * window.c (Fwindow_combination_limit): Revert to the only
4291 required argument and adjust docstring as suggested in
4292 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4293 by Martin Rudalics <rudalics@gmx.at>.
4295 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4297 Widely used frame validity and checking functions.
4298 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4299 * frame.c (decode_live_frame, decode_any_frame): New functions.
4300 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4301 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4302 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4303 (Fframe_pointer_visible_p): Use decode_any_frame.
4304 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
4305 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4306 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4307 (Fframe_focus): Likewise. Allow zero number of arguments.
4309 (frame_buffer_list, frame_buffer_predicate): Remove.
4310 * lisp.h (frame_buffer_predicate): Remove prototype.
4311 * buffer.c (Fother_buffer): Use decode_any_frame.
4312 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4313 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4314 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4315 (Fclose_font, Ffont_info): Use decode_live_frame.
4316 * fontset.c (check_fontset_name): Likewise.
4317 * terminal.c (Fframe_terminal): Likewise.
4318 * w32fns.c (check_x_frame): Likewise.
4319 * window.c (Fminibuffer_window, Fwindow_at)
4320 (Fcurrent_window_configuration): Likewise.
4321 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4322 Likewise. Allow zero number of arguments. Adjust docstring.
4323 * dispnew.c (Fredraw_frame): Likewise.
4324 * xfaces.c (frame_or_selected_frame): Remove.
4325 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4326 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4327 (Fframe_face_alist): Use decode_live_frame.
4328 * xfns.c (check_x_frame): Likewise.
4330 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4332 * window.c (quad): New function.
4333 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4334 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4335 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4336 (Fwindow_line_height): Use it.
4337 (Fwindow_fringes): Use list3.
4338 (Fwindow_scroll_bars): Use list4.
4339 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4340 (Fwindow_combination_limit): Allow zero number of arguments.
4342 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4344 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4346 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4347 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4348 file descriptor 2 for standard error. (Bug#12805)
4350 2012-11-05 Chong Yidong <cyd@gnu.org>
4352 * process.c (wait_reading_process_output): Revert previous change.
4354 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4356 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4357 This removes code that has been obsolete since around 1990.
4358 * callproc.c (Fcall_process):
4360 * process.c (create_process):
4361 * term.c (dissociate_if_controlling_tty):
4362 Assume setsid exists.
4363 * callproc.c (child_setup): Assume setpgid exists and behaves as
4364 per POSIX.1-1988 or later.
4365 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4366 * emacs.c (shut_down_emacs):
4367 * sysdep.c (sys_suspend, init_foreground_group):
4368 Assume getpgrp behaves as per POSIX.1-1998 or later.
4369 * msdos.c (setpgrp): Remove.
4370 (tcgetpgrp, setpgid, setsid): New functions.
4371 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4372 * term.c (no_controlling_tty): Remove; unused.
4373 * w32proc.c (setpgrp): Remove.
4374 (setsid, tcgetpgrp): New functions.
4376 Simplify by assuming __fpending.
4377 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4378 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4379 Do not assume that __fpending's result fits in int.
4381 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4383 Remove EMACS_OUTQSIZE+sleep hack.
4384 * dispnew.c (update_frame_1): Remove hack for terminals slower
4385 than 2400 bps, which throttled Emacs by having it sleep.
4386 This code hasn't worked since at least 2007, when the multi-tty stuff
4387 was added, and anyway those old terminals are long dead.
4388 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4389 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4391 Fix data-loss with --version (Bug#9574).
4392 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4393 as we can't assume that emacs_strerror is initialized, and strerror
4394 is good enough here.
4395 (main): Invoke atexit earlier, to catch earlier instances of
4396 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4398 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4400 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4401 (keyDown): Remap keypad keys to X11 virtual key codes.
4403 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4405 Fix data-loss with --batch (Bug#9574).
4406 * emacs.c: Include <close-stream.h>.
4407 (close_output_streams): New function.
4408 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4409 and handles errors appropriately.
4410 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4413 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4414 The symptom is a diagnostic "GLib-WARNING **: In call to
4415 g_spawn_sync(), exit status of a child process was requested but
4416 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4417 waitpid(), so exit status can't be returned." The diagnostic
4418 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4419 The real bug is a race condition between Emacs and glib: Emacs
4420 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4421 so that glib can't find it. Work around the bug by invoking
4422 waitpid only on subprocesses that Emacs itself creates.
4423 * process.c (create_process, record_child_status_change):
4424 Don't use special value -1 in pid field, as the caller now must
4425 know the pid rather than having the callee infer it.
4426 The inference was sometimes incorrect anyway, due to another race.
4427 (create_process): Set new 'alive' member if child is created.
4428 (process_status_retrieved): New function.
4429 (record_child_status_change): Use it.
4430 Accept negative 1st argument, which means to wait for the
4431 processes that Emacs already knows about. Move special-case code
4432 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4433 processes that have already been waited for, by testing and
4434 clearing new 'alive' member.
4435 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4436 now does this internally.
4437 (handle_child_signal): Let record_child_status_change do all
4438 the work, since we do not want to reap all exited child processes,
4439 only the child processes that Emacs itself created.
4440 * process.h (Lisp_Process): New boolean member 'alive'.
4442 Omit duplicate definitions no longer needed with gcc -g3.
4443 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4444 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4445 Define only as macros. There's no longer any need to also define
4446 these symbols as enums or as constants, since we now assume
4447 gcc -g3 when debugging.
4449 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4451 * lisp.mk: Adjust comments to the fact that term/internal is now
4452 loaded from loadup.el.
4454 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4455 (msdos_fatal_signal): New function.
4456 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4459 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4460 for GCC versions before 4.
4461 (emacs_raise): Define to call msdos_fatal_signal.
4463 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4464 iterator when starting in the middle of a display or overlay
4467 2012-11-03 Chong Yidong <cyd@gnu.org>
4469 * process.c (wait_reading_process_output): Clean up the last
4472 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4474 * process.c (wait_reading_process_output): Avoid a race condition
4475 with SIGIO delivery (Bug#11536).
4477 2012-11-03 Chong Yidong <cyd@gnu.org>
4479 * buffer.c (cursor_type): Untabify docstring.
4481 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4483 * frame.h (struct frame): Drop can_have_scroll_bars member
4484 which is meaningless for a long time. Adjust comments.
4485 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4486 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4488 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4490 * window.c (decode_next_window_args): Update window arg after
4491 calling decode_live_window and so fix crash reported at
4492 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4493 by Juanma Barranquero <lekktu@gmail.com>.
4494 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4495 * font.c (Ffont_at): Likewise.
4497 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4499 * widget.c (resize_cb): New function.
4500 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4501 (EmacsFrameResize): Check if all is up to date before changing frame
4504 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4506 Implement backtrace output for fatal errors on MS-Windows.
4507 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4508 (BACKTRACE_LIMIT_MAX): New macro.
4509 (w32_backtrace): New function.
4510 (emacs_abort): Use w32_backtrace when the user chooses not to
4511 attach a debugger. Update the text of the abort dialog.
4513 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4515 Window-related stuff cleanup here and there.
4516 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4517 Use decode_any_window.
4518 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4519 * xdisp.c (Fformat_mode_line): Likewise.
4520 * font.c (Ffont_at): Use decode_live_window.
4521 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4522 * window.c (decode_next_window_args): Likewise.
4523 (decode_any_window): Remove static.
4524 * window.h (decode_any_window): Add prototype.
4525 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4526 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4529 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4531 Remove pad from struct input_event.
4532 * termhooks.h (struct input_event): Remove padding field.
4534 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4535 member is never cons for a long time. Adjust comment.
4536 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4537 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4538 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4539 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4541 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4543 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4545 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4547 Fix crash when using Emacs as commit editor for git (Bug#12697).
4548 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4549 and it is configured in conf_post.h.
4550 (Fcall_process): Don't invoke both setsid and setpgid; the former
4551 is enough, if it exists.
4552 * callproc.c (Fcall_process, child_setup):
4553 * process.c (create_process): Use setpgid.
4554 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4556 * dispnew.c (init_display): Initialize the foreground group
4557 if we are running a tty display.
4558 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4559 * lisp.h (init_foreground_group): New decl.
4560 * sysdep.c (inherited_pgroup): New static var.
4561 (init_foreground_group, tcsetpgrp_without_stopping)
4562 (narrow_foreground_group, widen_foreground_group): New functions.
4563 (init_sys_modes): Narrow foreground group.
4564 (reset_sys_modes): Widen foreground group.
4566 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4568 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4570 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4572 * minibuf.c (read_minibuf): Restore current buffer since
4573 choose_minibuf_frame calling Fset_frame_selected_window may
4574 change it (Bug#12766).
4576 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4578 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4580 2012-10-30 Kenichi Handa <handa@gnu.org>
4582 * font.c (Ffont_at): If WINDOW is specified and it is not
4583 displaying the current buffer, signal an error.
4585 2012-10-29 Daniel Colascione <dancol@dancol.org>
4587 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4588 In preparation for fixing bug#12739, move these functions from
4591 * coding.h, coding.c: ... to here, and compile them only when
4592 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4593 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4595 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4597 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4598 (timer_loop, getitimer, setitimer): Use it instead of
4599 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4601 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4604 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

4616 * frame.c (x_set_font): Catch internal error.
4618 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4620 Avoid overflow in w32 implementation of interval timers.
4621 When possible, for ITIMER_PROF count only times the main thread
4623 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4624 'volatile ULONGLONG' types. All the other data which was
4625 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4626 (GetThreadTimes_Proc): New typedef.
4627 (w32_get_timer_time): New function, returns a suitable time value
4629 (timer_loop): Enter critical section when accessing ULONGLONG
4630 values of the itimer_data struct, as these accesses are no longer
4631 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4632 Remove unused variable.
4633 (init_timers): Initialize s_pfn_Get_Thread_Times.
4634 (start_timer_thread): Don't assign itimer->caller_thread here.
4635 (getitimer): Assign itimer->caller_thread here.

4641 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4642 mouse movement events if the menu bar is active. This avoids
4643 producing a busy "hour-glass" cursor by Windows if the mouse
4644 pointer is positioned over a tooltip shown for some menu item.
4646 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4648 Don't assume process IDs fit in int.
4649 * emacs.c (shut_down_emacs) [!DOS_NT]:
4650 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4651 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4652 Use pid_t, not int, to store process IDs, as 'int'
4653 is not wide enough on a few platforms (e.g., AIX and IRIX).
4655 2012-10-23 Kenichi Handa <handa@gnu.org>
4657 The following change is to make face-font-rescale-alist work

4683 * frame.c (Fmouse_position, Fmouse_pixel_position):
4684 * xdisp.c (produce_stretch_glyph):
4685 Declare local vars only when they're needed.
4686 This is clearer and avoids a warning on OpenBSD about unused vars.

4690 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4691 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4692 as our definition clashes with OpenBSD's.
4693 * xfaces.c (load_face_colors, check_lface_attrs)
4694 (get_lface_attributes_no_remap, get_lface_attributes)
4695 (lface_fully_specified_p, x_supports_face_attributes_p)
4696 (tty_supports_face_attributes_p, face_fontset, realize_face)
4697 (realize_x_face, realize_tty_face):
4698 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4699 merely Lisp_Object *. This is more informative and avoids
4700 a warning on OpenBSD about accessing beyond an object's size.
4702 2012-10-20 Chong Yidong <cyd@gnu.org>
4704 * lread.c (Fload): Doc fix (Bug#12592).

4730 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4731 (staticpro): If we run out of staticpro slots, die with an
4732 informative error instead of just calling emacs_abort.
4734 2012-10-18 Martin Rudalics <rudalics@gmx.at>

4994 the same pointer-to-int (now pointer-to-boolean) &input_pending,

5047 2012-10-08 Daniel Colascione <dancol@dancol.org>
5049 * xdisp.c (start_hourglass): Call w32_note_current_window when
5050 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5051 build that caused Emacs to display the hourglass cursor forever.
5053 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5054 which is broken under remote desktop, calculate the number of
5055 colors available for a display based on the display's number of

5086 ($(BLD)/w32menu.$(O)):
5087 ($(BLD)/w32proc.$(O)): Add w32common.h.
5089 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5091 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5093 2012-10-08 Daniel Colascione <dancol@dancol.org>
5095 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5096 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5097 accidental message numbering hole. Change other messages to
5100 * w32select.h (HAVE_W32SELECT): Remove.
5102 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5103 w32common.h instead of w32heap.h.
5105 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5106 (get_allocation_unit, get_processor_type, get_w32_major_version)
5107 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5108 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5109 (OS_NT, os_subtype, cache_system_info): Move declarations to
5112 * w32heap.c: Include w32common.h.
5113 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5114 (w32_minor_version, w32_build_number, w32_subtype):
5115 Remove duplicate definitions.
5117 * w32fns.c: Include w32common.h; include w32heap.h only in
5120 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5121 Use `report_file_error' instead of `error' in order to better
5122 inform users of what went wrong. Increase NTGUI_UNICODE file
5123 dialog box file name length to 32k, the maximum allowed by the NT
5126 * w32common.h: New file.
5127 (ROUND_UP, ROUND_DOWN, get_page_size)
5128 (get_allocation_unit, get_processor_type, get_w32_major_version)
5129 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5130 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5131 (OS_NT, os_subtype, cache_system_info): Move here.
5133 * unexw32.c, unexcw.c: Include w32common.h.
5135 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5136 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5137 to call syms_of_w32select.
5139 * cygw32.h: Remove obsolete EXFUN declarations.
5141 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5143 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5144 of w32inevt.o from SOME_MACHINE_OBJECTS.
5146 2012-10-08 Daniel Colascione <dancol@dancol.org>
5148 * image.c: Permanent fix for JPEG compilation issue --- limit
5149 jpeglib `boolean' redefinition to Cygwin builds.
5151 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5153 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5155 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5158 2012-10-08 Daniel Colascione <dancol@dancol.org>
5160 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5161 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5162 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5163 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5164 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5165 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5166 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5167 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5168 now a supported configuration.
5170 * Makefile.in: consolidate image variables into LIBIMAGE; add
5171 W32_OBJ and W32_LIBS. Compile new files.
5174 (_DebPrint) declare tracing facility for W32 debugging. We need
5175 to unify tracing later.
5177 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5178 unconditional use of W32 Unicode functions. Cygwin runs only on
5179 100% Unicode operating systems.
5181 * cygw32.c: New file. Define Cygwin-specific facilities.
5182 (Fcygwin_convert_path_to_windows)
5183 (Fcygwin_convert_path_from_windows): New user functions for
5184 accessing Cygwin path-munging routines.
5186 * cygw32.h: New file.
5187 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5188 UTF-16LE strings temporarily inside non-Lisp-visible string
5191 (w32_strerror): Just what it says on the tin.
5193 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5194 also run for Cygwin; both systems have the same problem with using
5195 GUI facilities in a forked child. Also call syms_of_cygw32,
5196 syms_of_w32select in correct places.
5198 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5199 needs fork-then-exec for daemon launching.
5201 * font.h: Include frame.h.
5203 * image.c: Use the image library cache machinery only when we're
5204 compiling for native WINDOWSNT; Cygwin can use shared libraries
5205 like any other Unixlike system.
5207 * keyboard.c: Clarify a comment regarding the input loop.
5209 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5210 functions directly instead of trying to detect at runtime that our
5211 host operating system supports them. We make this change for two
5212 reasons: Cygwin lacks support for the multibyte character
5213 conversion functions used by the legacy menu code, and Cygwin
5214 never needs to rely on non-Unicode APIs.
5216 * unexw32.c (hinst): Declare extern.
5218 * w32.c: Change header order;
5219 (w32_strerror): Move to w32fns.c because we need it for
5220 non-WINDOWSNT builds.
5222 * w32.h: Add #error macro to make sure we don't include w32.h for
5223 Cygwin builds. Remove w32select declarations.
5225 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5226 w32fns.c. w32console.c is WINDOWSNT-only.
5228 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5229 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5231 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5232 (w32_major_version, w32_minor_version, w32_build_number)
5233 (os_subtype, sound_type): Define here
5234 (w32_defined_color): Make color parameter const for consistency
5235 with other _defined_color functions.
5236 (w32_createwindow): Unconditionally call w32_init_class instead of
5237 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5238 through the code is complex and unnecessary because class
5239 registration is practically free.
5240 (w32_name_of_message): New EMACSDEBUG-only function.
5241 (Fset_message_beep): Move here
5242 (Fx_open_connection): Require that the display name for Windows be
5243 "w32" for consistency, emacsclient disambiguation, and maybe, one
5244 day, multi-window-system support.
5245 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5246 Cygwin files for W32 GUI facilities, since these clearly don't
5247 expect Cygwin names.
5248 (_DebPrint): Define.
5249 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5250 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5251 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5252 (w32_last_error): Remove.
5254 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5256 * w32heap.c (syspage_mask): Declare here.
5257 (cache_system_info): Remove.
5259 * w32inevt.c (faked_key): Define globally, not statically.
5260 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5261 (w32_console_toggle_lock_key): Move to w32fns.c.
5263 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5265 * w32proc.c (_DebPrint): Move to w32fns.c.
5266 * w32select.c: Include string.h, stdio.h for Cygwin.
5267 * w32select.h: New File.
5269 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5271 (w32_message_fd): New variable. Under Cygwin, holds the file
5272 descriptor the system used to tell us about pending thread
5275 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5276 that prevented compilation under non-WINDOWSNT systems.
5278 (w32_initialize): Open /dev/windows and assign it to
5279 w32_message_fd. Provide w32 feature.
5281 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5282 (WM_EMACS_INPUT_READY): add.
5283 (prepend_msg, w32_message_fd): Declare globally.
5286 (keyboard_handle): Use only when WINDOWSNT.
5287 (notify_msg_ready): New function. Posts a message to the main
5288 thread's message queue under CYGWIN, which wakes up the main
5289 thread from select(2) by making the /dev/windows file descriptor
5290 ready. Under WINDOWSNT, it sets an event the same way the old
5293 (post, prepend_msg): Actually call notify_msg_ready instead of
5294 setting the input event directly.
5296 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5298 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5299 but it still has blocs in it, don't return it to the system,
5300 instead of aborting. (Bug#12402)
5302 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5304 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5306 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5307 MAC_OS_X_VERSION_10_6.
5308 (syms_of_nsterm): Remove comment about Panther and above for
5310 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5311 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5312 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5314 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5315 MAC_OS_X_VERSION_10_4.
5317 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5318 MAC_OS_X_VERSION_10_2.
5320 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5322 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5323 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5325 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5326 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5327 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5328 Remove ns_in_resize check.
5329 (ns_clear_frame_area): Remove resize handle code.
5331 * nsfns.m (ns_in_resize): Remove.
5332 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5333 Remove ns_in_resize check.
5335 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5337 Improve sys_siglist detection.
5338 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5339 defined as a macro, as is done in Solaris.
5340 (sys_siglist_entries): New macro.
5341 (save_strsignal): Use it.
5342 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5343 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5345 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5347 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5348 fullscreen/Fullscreen.
5350 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5351 tobar_height is new.
5353 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5354 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5355 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5356 (windowDidResize:): Check for correct window if old style fullscreen.
5357 Capitalize word in comment. Remove incorrect comment.
5358 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5359 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5360 error in drawing background.
5361 (toggleFullScreen:): Remove comment. Rearrange calls.
5362 Set toolbar values to zero, save old height in tobar_height.
5363 Restore tool bar height when leaving fullscreen.
5364 (canBecomeMainWindow): New function.
5366 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5368 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5370 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5372 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5374 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5375 that time stamps of directories could also be changed.
5376 Don't request the too broad GENERIC_WRITE, only the more restrictive
5377 FILE_WRITE_ATTRIBUTES access rights.
5379 * fileio.c (Fset_file_times): Special-case ignoring errors for
5380 directories only on MSDOS, not on MS-Windows.
5382 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5384 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5386 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5388 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5389 see whether CreateFile failed.
5391 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5393 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5394 to avoid similar races.
5395 * keyboard.c (pending_signals): Now bool, not int.
5397 Port timers to OpenBSD, plus check for timer failures.
5398 OpenBSD problem reported by Han Boetes.
5399 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5401 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5402 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5403 like OpenBSD, which has timer_settime but does not declare it.
5404 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5405 whether to use itimerspec-related primitives. All uses of
5406 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5408 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5410 * profiler.c (handle_profiler_signal): Fix a malloc race
5411 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5413 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5415 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5417 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5419 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5420 consistent with the change in return value of 'safe_strsignal'.
5422 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5424 Prefer plain 'static' to 'static inline' (Bug#12541).
5425 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5426 (bidi_set_sor_type, bidi_push_embedding_level)
5427 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5428 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5429 (bidi_cache_search, bidi_cache_ensure_space)
5430 (bidi_cache_iterator_state, bidi_cache_find)
5431 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5432 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5433 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5434 Now 'static', not 'static inline'.
5436 Count overruns when profiling; change units to ns.
5437 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5438 Give extra weight to samples after overruns, to attempt to count
5439 the time more accurately.
5440 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5441 the underlying primitives nominally do ns.
5442 (Fprofiler_cpu_start): Document the change. Mention that
5443 the sampling intervals are only approximate.
5445 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5447 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5449 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5450 case for the special 0 coding-system.
5452 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5453 (Fmake_overlay): Remove redundant tests.
5454 (fix_start_end_in_overlays): Remove redundant recentering.
5456 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5458 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5459 Update dependencies.
5461 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5463 Fix a malloc race condition involving strsignal.
5464 A signal can arrive in the middle of a malloc, and Emacs's signal
5465 handler can invoke strsignal, which can invoke malloc, which is
5466 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5467 Fix it by altering the signal handler so that it does not invoke
5469 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5470 * process.c (status_message): Use const pointer, in case strsignal
5471 is #defined to safe_strsignal.
5472 * sysdep.c (sys_siglist, init_signals): Always define and
5473 initialize a substitute sys_siglist if the system does not define
5474 one, even if HAVE_STRSIGNAL.
5475 (safe_strsignal): Rename from strsignal. Always define,
5476 using sys_siglist. Return a const pointer.
5477 * syssignal.h (safe_strsignal): New decl.
5478 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5480 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5482 * w32proc.c (timer_loop): Fix code that waits for timer
5483 expiration, to avoid high CPU usage.
5485 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5487 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5488 (sweep_weak_table): Remove redundant prototypes.
5490 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5492 * emacs.c: Move the inclusion of TERM_HEADER after including
5493 windows.h on WINDOWSNT. This avoids compilation problems with
5496 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5498 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5499 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5500 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5501 as the previous version used 'void *'.
5503 * ralloc.c (ROUNDUP): Fix last change.
5504 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5507 * w32proc.c <disable_itimers>: New static flag.
5508 (init_timers): Initialize it to zero, after creating the critical
5509 sections used by the timer threads.
5510 (term_timers): Set to 1 before deleting the critical sections.
5511 (getitimer, setitimer): If disable_itimers is non-zero, return an
5512 error indication without doing anything. Reported by Fabrice
5513 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5514 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5516 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5519 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5520 term_ntproc after all the other bookkeeping, to get timers working
5521 as long as possible.
5523 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5525 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5526 Suggested by Juri Linkov in
5527 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5529 Prefer plain 'static' to 'static inline' (Bug#12541).
5530 With static functions, modern compilers inline pretty well by
5531 themselves; advice from programmers often hurts as much as it helps.
5532 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5533 this change shrinks the text size of the Emacs executable by 1.1%
5534 without affecting CPU significantly in my benchmark.
5535 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
5536 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
5537 (mark_maybe_object, mark_maybe_pointer, bounded_number):
5538 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
5539 (bset_auto_fill_function, bset_auto_save_file_format)
5540 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

5828 (handle_profiler_signal): Rename from sigprof_handler_1,
5829 for consistency with other handlers. Do not check whether
5830 cpu_log is a hash-table if garbage collecting, since it

5833 for consistency with other handlers.
5834 (setup_cpu_timer): New function, with much of what used to be in

5836 Prefer timer_settime if available, and prefer
5837 thread cputime clocks, then process cputime clocks, then
5838 monotonic clocks, to the old realtime clock. Use make_timeval
5839 to round more-correctly when falling back to setitimer.
5840 (Fprofiler_cpu_start): Use it.
5841 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5907 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5908 Since this stuff is now private to charset.c, there's no need for
5909 a public macro and no need to inline by hand.

5983 (sys_kill): Improve commentary.
5985 * w32.c (term_ntproc): Accept (and ignore) one argument, for

5988 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5989 install term_ntproc as a signal handler for SIGABRT, as that
5990 should be done by the dumped Emacs.

6019 now return bool, not int. All uses changed.
6020 * image.c: Omit unnecessary static decls.
6021 (x_create_bitmap_mask, x_build_heuristic_mask):
6022 Return void, not int, since callers don't care about the return value.

6057 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6059 Move pid_t related decls out of lisp.h.
6060 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6061 (interruptible_wait_for_termination):
6062 Move these decls from lisp.h to syswait.h, since they use pid_t.
6063 Needed on FreeBSD; see Herbert J. Skuhra in
6064 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6065 * callproc.c: Include syswait.h.

6085 Use bool for boolean.
6086 * gtkutil.c (xg_update_frame_menubar):

6092 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6094 * makefile.w32-in (BLOCKINPUT_H): Remove.

6111 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6113 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6114 fatal_error_backtrace.
6116 * w32proc.c (sys_kill): Undo last change: don't do anything when
6117 invoked to deliver SIGABRT to our own process. This is now
6118 handled by emacs_raise.
6120 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6122 * w32term.c (w32_read_socket): Remove leftover reference to
6123 interrupt_input_pending.
6125 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6127 Do not use SA_NODEFER.
6128 Problem reported by Dani Moncayo in
6129 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6131 * sysdep.c (emacs_abort): Do not reset signal handler.
6132 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6133 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6134 wanted even on POSIXish hosts, and it doesn't work on Windows.
6136 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6138 * xterm.c (x_term_init): Call fixup_locale before and after calling
6139 gtk_init (Bug#12392).
6141 2012-09-23 Chong Yidong <cyd@gnu.org>
6143 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6144 Vdynamic_library_alist.
6146 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6147 (Fgnutls_available_p): Caller changed.
6149 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6150 (Flibxml_parse_xml_region): Likewise.
6152 * dispextern.h (struct image_type): Remove arg from init function.
6154 * image.c (Finit_image_library, lookup_image_type)
6155 (define_image_type): Remove now-unneeded second arg.
6156 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6157 (init_tiff_functions, init_gif_functions, init_svg_functions):
6158 Arglist and w32_delayed_load calling convention changed.
6159 (gs_type): Remove init_gs_functions; there is no such function.
6160 (valid_image_p, make_image): Fix caller to lookup_image_type.
6162 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6164 Simplify and avoid signal-handling races (Bug#12471).
6166 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6167 Avoid recursive loop if there's a fatal error in the function itself.
6168 * atimer.c (pending_atimers):
6169 * blockinput.h: Don't include "atimer.h"; no longer needed.
6170 (interrupt_input_pending): Remove. All uses removed.
6171 pending_signals now counts both atimers and ordinary interrupts.
6172 This is less racy than having three separate pending-signal flags.
6173 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6175 Rename from their upper-case counterparts BLOCK_INPUT,
6176 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6177 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6178 This makes it easier to access volatile variables more accurately.
6179 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6180 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6181 that's more reliable if the code is buggy and sets
6182 interrupt_input_blocked to a negative value. All uses changed.
6183 * atimer.c (deliver_alarm_signal):
6184 Remove. No need to deliver this to the parent; any thread can
6185 handle this signal now. All uses replaced by underlying handler.
6186 * atimer.c (turn_on_atimers):
6187 * dispnew.c (handle_window_change_signal):
6188 * emacs.c (handle_danger_signal):
6189 * keyboard.c (kbd_buffer_get_event):
6190 Don't reestablish signal handler; not needed with sigaction.
6191 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6193 Rework to avoid unnecessary accesses to volatile variables.
6194 (UNBLOCK_INPUT_TO): Now a function.
6195 (totally_unblock_input, unblock_input): New decls.
6196 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6197 (init_data): Remove. Necessary stuff now done in init_signal.
6198 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6199 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6200 (fatal_error_code): Remove; no longer needed.
6201 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6202 it doesn't always backtrace. All uses changed. No need to reset
6203 signal to default, since sigaction and/or die does that for us now.
6204 Use emacs_raise (FOO), not kill (getpid (), FOO).
6205 (main): Check more-accurately whether we're dumping.
6206 Move fatal-error setup to sysdep.c
6207 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6208 * gtkutil.c (xg_get_file_name, xg_get_font):
6209 Remove no-longer-needed signal-mask manipulation.
6210 * keyboard.c, process.c (POLL_FOR_INPUT):
6211 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6212 * keyboard.c (read_avail_input): Remove.
6213 All uses replaced by gobble_input.
6214 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6215 (kbd_buffer_store_event_hold, gobble_input):
6216 (record_asynch_buffer_change) [USABLE_SIGIO]:
6217 (store_user_signal_events):
6218 No need to mess with signal mask.
6219 (gobble_input): If blocking input and there are terminals, simply
6220 set pending_signals to 1 and return. All hooks changed to not
6221 worry about whether input is blocked.
6222 (process_pending_signals): Clear pending_signals before processing
6223 them, in case a signal comes in while we're processing.
6224 By convention callers now test pending_signals before calling us.
6225 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6226 New functions, to support changes to blockinput.h.
6227 (handle_input_available_signal): Now extern.
6228 (reinvoke_input_signal): Remove. All uses replaced by
6230 (quit_count): Now volatile, since a signal handler uses it.
6231 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6232 All callers changed. Block SIGINT only if not already blocked.
6233 Clear sigmask reliably, even if Fsignal returns, which it can.
6234 Omit unnecessary accesses to volatile var.
6235 (quit_throw_to_read_char): No need to restore sigmask.
6236 * keyboard.c (gobble_input, handle_user_signal):
6237 * process.c (wait_reading_process_output):
6238 Call signal-handling code rather than killing ourselves.
6239 * lisp.h: Include <float.h>, for...
6240 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6241 (pending_signals): Now volatile.
6242 (syms_of_data): Now const if IEEE floating point.
6243 (handle_input_available_signal) [USABLE_SIGIO]:
6244 (terminate_due_to_signal, record_child_status_change): New decls.
6245 * process.c (create_process): Avoid disaster if memory is exhausted
6246 while we're processing a vfork, by tightening the critical section
6248 (send_process_frame, process_sent_to, handle_pipe_signal)
6249 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6251 (send_process): No need for setjmp/longjmp any more, since the
6252 SIGPIPE stuff is now gone. Instead, report an error if errno
6254 (record_child_status_change): Now extern. PID and W are now args.
6255 Return void, not bool. All callers changed.
6256 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6257 Remove. All uses removed. This bug should be fixed now in a
6259 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6260 and record the child status change directly. This avoids the
6261 need to futz with the signal mask.
6262 (process_fatal_action): Move here from emacs.c.
6263 (emacs_sigaction_flags): New function, containing
6264 much of what used to be in emacs_sigaction_init.
6265 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6266 caught by emacs, to make races less likely.
6267 (deliver_process_signal): Rename from handle_on_main_thread.
6269 (BACKTRACE_LIMIT_MAX): Now at top level.
6270 (thread_backtrace_buffer, threadback_backtrace_pointers):
6272 (deliver_thread_signal, deliver_fatal_thread_signal):
6273 New functions, for more-accurate delivery of thread-specific signals.
6274 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6275 (deliver_arith_signal): Handle in this thread, not
6276 in the main thread, since it's triggered by this thread.
6277 (maybe_fatal_sig): New function.
6278 (init_signals): New arg DUMPING so that we can be more accurate
6279 about whether we're dumping. Caller changed.
6280 Treat thread-specific signals differently from process-general signals.
6281 Block all signals while handling fatal error; that's safer.
6282 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6284 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6285 Ignore SIGPIPE unless batch.
6286 (emacs_backtrace): Output backtrace for the appropriate thread,
6287 which is not necessarily the main thread.
6288 * syssignal.h: Include <stdbool.h>.
6289 (emacs_raise): New macro.
6290 * xterm.c (x_connection_signal): Remove; no longer needed
6291 now that we use sigaction.
6292 (x_connection_closed): No need to mess with sigmask now.
6293 (x_initialize): No need to reset SIGPIPE handler here, since
6294 init_signals does this for us now.
6296 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6298 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6299 background rect may be larger (Bug#12245).
6301 2012-09-23 Chong Yidong <cyd@gnu.org>
6303 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6305 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6307 * .gdbinit: Just stop at fatal_error_backtrace.
6308 See Stefan Monnier's request in
6309 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6310 Remove no-longer-used query of system type.
6312 2012-09-22 Chong Yidong <cyd@gnu.org>
6314 * search.c (Freplace_match): Doc fix (Bug#12325).
6316 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6318 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6319 (Fline_end_position): Doc fix.
6321 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6323 2012-09-22 Chong Yidong <cyd@gnu.org>
6325 * dispextern.h (struct image_type): Add new slot, storing a type
6326 initialization function.
6328 * image.c (define_image_type): Call the image initializer function
6329 if it is defined. Arguments and return value changed.
6330 (valid_image_p, make_image): Callers changed.
6331 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6332 (gif_type, imagemagick_type, svg_type, gs_type):
6333 Add initialization functions.
6334 (Finit_image_library): Call lookup_image_type.
6335 (CHECK_LIB_AVAILABLE): Macro deleted.
6336 (lookup_image_type): Call define_image_type here, rather than via
6337 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6338 (syms_of_image): Move define_image_type calls for xbm_type and
6339 pbm_type to lookup_image_type.
6341 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6343 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6344 'idle_timers' from here ...
6345 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6346 lists, to avoid infloops when the timer does something stupid,
6347 like reinvoke itself with the same or smaller time-out.
6350 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6352 * window.c (Fsplit_window_internal): Handle only Qt value of
6353 Vwindow_combination_limit separately.
6354 (Qtemp_buffer_resize): New symbol.
6355 (Vwindow_combination_limit): New default value.
6358 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6360 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6361 the new overlay string. (Bug#10159)
6363 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6365 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6366 or that fprintf is async-signal-safe. POSIX doesn't require
6369 2012-09-22 Chong Yidong <cyd@gnu.org>
6371 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6374 2012-09-22 Kenichi Handa <handa@gnu.org>
6376 * composite.c (composition_reseat_it): Handle the case that a
6377 grapheme cluster is not covered by a single font (Bug#12352).
6379 2012-09-21 Chong Yidong <cyd@gnu.org>
6381 * image.c (define_image_type): Avoid adding duplicate types to
6382 image_types (Bug#12463). Suggested by Jörg Walter.
6384 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6386 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6387 (print_load_command_name): Add case LC_DATA_IN_CODE.
6388 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6390 2012-09-21 Glenn Morris <rgm@gnu.org>
6392 * eval.c (Frun_hook_with_args_until_success)
6393 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6395 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6397 * fileio.c (Ffile_selinux_context): Only call freecon when
6398 lgetfilecon succeeded.
6399 (Fset_file_selinux_context): Likewise. (Bug#12444)
6401 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6403 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6404 reordering, locate the cursor by calling set_cursor_from_row; if
6405 that fails, clear the desired glyph matrix before returning a
6406 failure indication to the caller. Fixes leaving garbled display
6407 when fast scrolling with a down-key. (Bug#12403)
6408 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6409 scrolling through multibyte text.
6411 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6413 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6414 calling mark_vectorlike since that's the one that marks the window.
6415 (mark_discard_killed_buffers): Mark the final cdr.
6416 * window.h (struct window): Move prev/next_buffers to the
6417 non-standard fields.
6418 * window.c (make_window): Initialize prev/next_buffers manually.
6420 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6422 Omit unused arg EXPECTED from socket hooks.

6427 * w32term.c (w32_read_socket):
6428 * xterm.c (XTread_socket):
6429 Omit unused arg EXPECTED. All callers changed.
6430 (store_user_signal_events): Return void, not int, since callers no
6431 longer care about the return value. All uses changed.
6433 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6435 * w32gui.h (XParseGeometry): Do not declare.
6437 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6439 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6440 Ignore 'expected'. See Eli Zaretskii in
6441 <http://bugs.gnu.org/12471#8> (last line).
6443 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6444 (XParseGeometry): Now static. Substitute extremal values for
6445 values that are out of range.
6447 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6449 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6451 * nsfns.m (XParseGeometry): Remove.
6452 (Fx_create_frame): Call x_set_offset to correctly interpret
6453 top_pos in geometry.
6455 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6456 (Fx_parse_geometry): If there is a space in string, call
6457 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6459 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6461 * search.c (scan_buffer): Use character positions in calls to
6462 region_cache_forward and region_cache_backward, not byte
6463 positions. (Bug#12196)
6465 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6466 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6468 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6469 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6470 emacs_blocked_malloc, now deleted.
6472 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6474 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6475 The workaround was for improving performance on Solaris 2.4, but
6476 is getting in the way now. Emacs will still work if someone is
6477 still running Solaris 2.4 in a museum somewhere; Sun dropped
6478 support for Solaris 2.4 in 2003.
6479 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6480 * process.c (create_process) [HAVE_WORKING_VFORK]:
6481 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6482 since Emacs no longer uses vfork on that platform.
6484 2012-09-17 Glenn Morris <rgm@gnu.org>
6486 * emacs.c: Use COPYRIGHT.
6488 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6490 Remove configure's --without-sync-input option (Bug#12450).
6491 When auditing signal-handling in preparation for cleaning it up,
6492 I found that SYNC_INPUT has race conditions and would be a real
6493 pain to fix. Since it's an undocumented and deprecated
6494 configure-time option, now seems like a good time to remove it.
6495 Also see <http://bugs.gnu.org/11080#16>.
6496 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6497 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6498 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6499 (malloc_hysteresis):
6500 (check_depth) [XMALLOC_OVERRUN_CHECK]:

6505 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6506 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6507 Remove. All uses removed.
6508 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6509 implementation, one that depends on whether the new macro
6510 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6512 * atimer.c (run_timers, handle_alarm_signal):
6513 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6514 (handle_async_input, process_pending_signals)

6524 * eval.c (handling_signal): Remove. All uses removed.
6525 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6526 All uses replaced with the SYNC_INPUT version.
6527 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6529 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6532 * font.c (Ffont_shape_gstring): Remove unused local.
6534 2012-09-16 Glenn Morris <rgm@gnu.org>
6536 * Makefile.in (clean): No longer run nextstep's clean.
6538 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6540 (ns-app): Move here from ns.mk, and simplify.
6541 (clean): Simplify nextstep entry.
6542 * ns.mk: Remove file.
6544 2012-09-17 Kenichi Handa <handa@gnu.org>
6546 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6547 not covert the last few charactes.
6549 2012-09-16 Kenichi Handa <handa@gnu.org>
6551 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6552 here, but just check the validity of glyphs in the glyph-string.
6554 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6556 * window.c (Fwindow_parameter, Fset_window_parameter):
6557 Accept any window as argument (Bug#12452).
6559 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6561 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6562 to ns_term_init to avoid memory leak.
6564 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6565 explicit retain/release.
6566 (ns_term_init): Only allow one display. Initialize outerpool and
6569 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6571 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6572 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6573 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6574 the Microsoft problem in a different way, by altering ../nt/config.nt.
6576 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6591 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6592 by lisp.h. This completes removal of setjmp.h inclusion
6593 erroneously announced in the previous commit. (Bug#12446)
6595 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6598 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6599 not defined as a macro. The latter happens on MS-Windows.
6602 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6604 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6605 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6606 Some instances of '#include <setjmp.h>' removed, if the
6607 only reason for the instance was because "lisp.h" was included.
6608 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6609 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6610 and _longjmp with the new symbols. Emacs already uses _setjmp if
6611 available, so this change affects only POSIXish hosts that have
6612 sigsetjmp but not _setjmp, such as some versions of Solaris and
6613 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6614 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6615 (png_load_body) [HAVE_PNG]:
6616 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6617 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6618 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6619 since PNG requires jmp_buf. This is the only exception to the
6620 general rule that we now use sys_setjmp and sys_longjmp.
6621 This exception is OK since this code does not change the signal
6622 mask or longjmp out of a signal handler.
6624 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6626 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6627 Include "syssignal.h", for 'main_thread'.
6629 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6631 Avoid out-of-range marker position (Bug#12426).
6632 * insdel.c (replace_range, replace_range_2):
6633 Adjust markers before overlays, as suggested by comments.
6634 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6635 Remove redundant check before calling offset_intervals.
6637 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6639 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6640 current buffer (Bug#12387).
6642 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6644 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6646 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6648 Use a more backwards-compatible timer format (Bug#12430).
6649 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6650 vector element, not from the 4th, since PSECS is now at the end.
6651 (Fcurrent_idle_time): Doc fix.
6653 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6655 Function to mark objects and remove killed buffers at once.
6656 * alloc.c (discard_killed_buffers): Rename to ...
6657 (mark_discard_killed buffers) ... new name. Add marking
6658 of remaining objects. Fix comment. Adjust users.
6659 (mark_object): Do not touch frame buffer lists here.
6660 * frame.c (delete_frame): Reset frame buffer lists here.
6662 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6664 Better workaround for GNOME bug when --enable-gcc-warnings.
6665 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6666 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6667 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6669 Simplify SIGIO usage (Bug#12408).
6670 The code that dealt with SIGIO was crufty and confusing, e.g., it
6671 played tricks like "#undef SIGIO" but these tricks were not used
6672 consistently. Simplify mostly by not #undeffing standard symbols,
6673 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6674 or not as we please) rather than "defined SIGIO" (standard symbol
6675 that we probably shouldn't #undef).
6676 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6677 Modules that need it can include it.
6678 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6679 * dispextern.h (ignore_sigio): New decl.
6680 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6681 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6682 * emacs.c (shut_down_emacs):
6683 * keyboard.c (kbd_buffer_store_event_hold):
6684 Use ignore_sigio rather than invoking 'signal' directly.
6685 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6687 (FIONREAD, SIGIO): Do not #undef.
6688 (tty_read_avail_input): Use #error rather than a syntax error.
6689 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6690 for I_PIPE, used by SETUP_SLAVE_PTY.
6691 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6692 * sysdep.c (croak): Remove; no longer needed. This bit of
6693 temporary code, with Fred N. Fish's comment that it's temporary,
6694 has been in Emacs since at least 1992!
6695 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6696 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6697 * syssignal.h (croak): Remove decl.
6698 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6699 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6700 now that we're termios-only.
6701 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6702 * term.c (dissociate_if_controlling_tty): Use #error rather than
6705 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6706 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6707 to work around GNOME bug 683906.
6708 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6709 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6710 This works around GCC bug 54561.
6712 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6714 More fixes for 'volatile' and setjmp/longjmp.
6715 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6716 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6717 (png_load_body) [HAVE_PNG]:
6718 (jpeg_load_body) [HAVE_JPEG]:
6719 New function, with most of the old parent function's body.
6720 (png_load) [HAVE_PNG]:
6721 (jpeg_load) [HAVE_JPEG]:
6722 Invoke the new function, to avoid longjmp munging our locals.
6723 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6724 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6725 longjmp is passed 2, as the C standard doesn't guarantee this.
6726 Instead, store the failure code into mgr->failure_code.
6728 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6730 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6731 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6732 (syms_of_keyboard): Remove support for unread-command-char.
6734 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6736 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6737 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6738 violation. (Bug#12426)
6740 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6742 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6744 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6746 * eval.c: Add `inhibit-debugger'.
6747 (Qinhibit_debugger): New symbol.
6748 (call_debugger): Bind it instead of Qdebug_on_error.
6749 (maybe_call_debugger): Test Vinhibit_debugger.
6750 (syms_of_eval): Define inhibit-debugger.
6751 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6752 (syms_of_xdisp): Remove inhibit-debug-on-message.
6754 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6756 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6757 If a nonvolatile local variable is written before a _longjmp to
6758 the frame containing the variable, and is read after the _longjmp,
6759 the value read is indeterminate. Some local variables of type
6760 'struct handler' and 'struct catchtag' are used in this way, so
6761 mark each of their slots as volatile if the slot can be set before
6762 _longjmp and read afterwards.
6763 * lisp.h (struct handler): var and chosen_clause are now volatile.
6764 (struct catchtag): val, next, and pdlcount are now volatile.
6766 * bidi.c (bidi_push_it, bidi_pop_it):
6767 * fns.c (copy_hash_table):
6768 * image.c (define_image_type):
6769 * keyboard.c (kbd_buffer_store_event_hold):
6770 * process.c (Fprocess_send_eof):
6771 * xfaces.c (x_create_gc) [HAVE_NS]:
6772 * xgselect.c (xg_select):
6773 Prefer assignment to memcpy when either will do.
6775 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6776 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6777 time an item is removed. No need to mark this function 'inline';
6778 the compiler knows better than we do.
6780 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6782 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6783 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6784 to change_frame_size (Bug#12388).
6785 (windowDidResize:): Pass YES to updateFrameSize.
6787 * nsterm.h: Add delay parameter to updateFrameSize.
6789 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6791 Discard killed buffers from deleted window and frame objects.
6792 This reduces an amount of references to killed buffers and
6793 helps GC to reclaim them faster.
6794 * alloc.c (discard_killed_buffers): New function.
6795 (mark_object): Use it for deleted windows and frames.
6796 (mark_object): If symbol's value is set up for a killed buffer
6797 or deleted frame, restore its global binding.
6798 * data.c (swap_in_global_binding): Add GC notice.
6799 (swap_in_symval_forwarding): Use convenient set_blv_where.
6800 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6801 * window.h: ... to here.
6803 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6805 Convenient macro to check whether the buffer is live.
6806 * buffer.h (BUFFER_LIVE_P): New macro.
6807 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6808 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6810 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6812 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6813 composition cases (Bug#12364).
6815 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6816 overhang of succeeding glyphs overlapping box cursor.
6818 * w32term.c (x_draw_glyph_string): Likewise.
6820 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6822 Simplify, document, and port floating-point (Bug#12381).
6823 The porting part of this patch fixes bugs on non-IEEE platforms
6824 with frexp, ldexp, logb.
6825 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6827 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6828 support, by removing commented-out code and briefly listing the
6829 C89 functions excluded. The commented-out stuff was confusing
6830 maintenance, e.g., we thought we needed cbrt but it was commented out.
6831 (logb): Remove decl; no longer needed.
6832 (isfinite): New macro, if not already supplied.
6833 (isnan): Don't replace any existing macro.
6834 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6835 are present on all C89 platforms.
6836 (Ffrexp): Do not special-case zero, as frexp does the right thing
6838 (Flogb): Do not use logb, as it doesn't have the desired meaning
6839 on hosts that use non-base-2 floating point. Instead, stick with
6840 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6841 frexp, to avoid getting an unspecified result.
6843 * xdisp.c (Qinhibit_debug_on_message): Now static.
6845 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6847 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6848 NSBezierPath (Bug#12131).
6850 2012-09-10 Chong Yidong <cyd@gnu.org>
6852 * fns.c (Fdelq, Fdelete): Doc fix.
6854 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6856 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6857 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6859 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6861 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6862 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6865 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6867 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6868 left fringe if the window has a left margin. This avoids leaving
6869 traces of the cursor because its leftmost pixel is not drawn over.
6871 * dispnew.c (update_window_line): When the left margin area of a
6872 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6873 that screen line. (Bug#12277)
6875 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6877 Assume C89 or later for math functions (Bug#12381).
6878 This simplifies the code, and makes it a bit smaller and faster,
6879 and (most important) makes it easier to clean up signal handling
6880 since we can stop worring about floating-point exceptions in
6881 library code. That was a problem before C89, but the problem
6882 went away many years ago on all practical Emacs targets.
6883 * data.c, image.c, lread.c, print.c:
6884 Don't include <math.h>; no longer needed.
6885 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6886 might be autoconfigured, as that never happens.
6888 * doprnt.c (DBL_MAX_10_EXP):
6889 * print.c (DBL_DIG):
6890 Remove. C89 or later always defines these.
6891 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6892 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6893 (arith_error, domain_error, domain_error2):
6894 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6895 no longer needed -- we simply return what C returns. All uses removed.
6896 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6898 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6899 Remove. All uses expanded, as these macros are no longer used
6900 more than once and are now more trouble than they're worth.
6901 (Ftan): Use tan, not sin / cos.
6902 (Flogb): Assume C89 frexp.
6903 (fmod_float): Assume C89 fmod.
6904 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6905 (init_floatfns): Remove. All uses removed.
6907 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6909 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6910 compositeToPoint for OSX < 10.6 (Bug#12390).
6912 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6914 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6915 This produces more-accurate results.
6917 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6919 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6920 changes (Bug#12088).
6922 2012-09-08 Chong Yidong <cyd@gnu.org>
6924 * syntax.c (Fstring_to_syntax): Doc fix.
6926 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6928 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6929 in the internal border.
6930 (x_set_window_size): Remove static variables and their usage.
6931 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6932 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6933 Remove fringe/internal border adjustment (Bug#11052).
6934 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6935 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6936 (ns_fix_rect_ibw): Remove.
6937 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6938 (ns_dumpglyphs_box_or_relief): Ditto.
6939 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6941 (ns_dumpglyphs_image): Ditto.
6942 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6944 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6945 their usage. Add fringe_extended_p and its use as in other terms.
6946 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6947 scroll bar was removed.
6948 (updateFrameSize): New function.
6949 (windowDidResize): Move code to updateFrameSize and call it.
6951 * nsterm.h (EmacsView): Add updateFrameSize.
6953 2012-09-07 Chong Yidong <cyd@gnu.org>
6955 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6957 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6959 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6961 More signal-handler cleanup (Bug#12327).
6962 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6963 Problem introduced when merging patches. Noted by Eli Zaretskii in
6964 <http://bugs.gnu.org/12327#67>.
6965 * floatfns.c: Comment fix.
6966 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6967 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6968 and anyway the declaration is harmless even if SIGDANGER is not defined.
6969 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6970 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6971 source files not surprisingly expected syssignal.h to define, or
6972 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6973 Include <sys/ioctl.h>, for FIONREAD.
6974 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6975 This eliminates a problem whereby other files mysteriously had
6976 to include "syssignal.h" before including "systty.h" if they
6977 wanted to use "#ifdef SIGIO".
6979 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6981 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6983 * w32.c (sigemptyset): Empty the set.
6984 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6986 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6988 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6990 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6991 (mark_object): Likewise for frame objects.
6993 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6995 * syssignal.h (handle_on_main_thread): Always declare,
6996 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6997 This ports to platforms without HAVE_PTHREAD.
6999 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7001 Signal-handler cleanup (Bug#12327).
7002 Emacs's signal handlers were written in the old 4.2BSD style with
7003 sigblock and sigmask and so forth, and this led to some
7004 inefficiencies and confusion. Rewrite these to use
7005 pthread_sigmask etc. without copying signal sets around. Also,
7006 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7007 'signal', and instead use functions that do not attempt to take
7008 over the system name space. This patch causes Emacs's text
7009 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7010 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7011 Do not include <signal.h> or "syssignal.h", as these
7012 modules do not use signals.
7013 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7014 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7015 Do not include <signal.h>, as "syssignal.h" does that for us now.
7016 * atimer.c (sigmask_atimers): New function.
7017 (block_atimers, unblock_atimers): New functions,
7018 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7020 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7021 no longer needed here.
7022 * emacs.c (main): Inspect existing signal handler with sigaction,
7023 so that there's no need to block and unblock SIGHUP.
7024 * sysdep.c (struct save_signal): New member 'action', replacing
7025 old member 'handler'.
7026 (save_signal_handlers, restore_signal_handlers):
7027 Use sigaction instead of 'signal' to save and restore.
7028 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7029 New function. All users of 'signal' modified to use set_sighandler
7030 if they're writeonly, and to use sys_signal if they're read+write.
7031 (emacs_sigaction_init, forwarded_signal): New functions.
7032 (sys_signal): Remove. All uses replaced by calls to sigaction
7033 and emacs_sigaction_init, or by direct calls to 'signal'.
7034 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7035 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7036 all uses replaced by pthread_sigmask etc. calls.
7037 * syssignal.h: Include <signal.h>.
7038 (emacs_sigaction_init, forwarded_signal): New decls.
7039 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7040 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7041 (sigmask, sys_sigmask): Remove; no longer needed.
7042 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7043 (sigblock, sigunblock, sigfree):
7044 (sigsetmask) [!defined sigsetmask]:
7045 Remove. All uses replaced by pthread_sigmask.
7046 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7047 no longer need to be replaced, and its typical old uses
7048 are now done via emacs_sigaction_init and sigaction.
7049 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7050 (sys_sigdel): Remove; unused.
7051 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7053 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7055 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7056 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7058 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7060 Explicitly mark buffer_defaults and buffer_local_symbols.
7061 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7062 mark_local_symbols here.
7063 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7064 since special buffers aren't marked here any more.
7065 (allocate_buffer): Chain new buffer with all_buffers here...
7066 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7068 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7069 (syms_of_buffer): Remove staticpro of the above.
7070 (init_buffer_once): Set names for buffer_defaults and
7071 buffer_local_symbols.
7073 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7075 Use bool for booleans in font-related modules.
7076 * font.c (font_intern_prop, font_style_to_value)
7077 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7078 (generate_otf_features, font_check_otf_features, font_check_otf)
7079 (font_match_p, font_list_entities, font_at):
7080 * fontset.c (fontset_id_valid_p, reorder_font_vector
7081 (fontset_find_font, Fset_fontset_font)
7082 (face_suitable_for_char_p) [0]:
7083 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7084 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7085 (m17n_flt_initialized, ftfont_shape_by_flt):
7086 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7087 * nsfont.m (nsfont_draw):
7088 * w32font.c (w32font_draw):
7089 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7090 Use bool for booleans.
7091 * font.h: Adjust to above API changes.
7092 (struct font, struct font_driver, struct font_driver_list):
7093 Use bool for booleans.
7094 (struct font): Remove useless member encoding_type.
7096 * fontset.c, xftfont.c: Omit unnecessary static decls.
7098 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7100 * alloc.c (mark_object): Revert window marking code
7101 since it's unsafe for the Fset_window_configuration.
7103 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7105 Fix race conditions with signal handlers and errno (Bug#12327).
7106 Be more systematic about preserving errno whenever a signal
7107 handler returns, even if it's not in the main thread. Do this by
7108 renaming signal handlers to distinguish between signal delivery
7109 and signal handling. All uses changed.
7110 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7111 * data.c (deliver_arith_signal): Rename from arith_error.
7112 * dispnew.c (deliver_window_change_signal): Rename from
7113 window_change_signal.
7114 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7115 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7116 * keyboard.c (deliver_input_available_signal): Rename from
7117 input_available_signal.
7118 (deliver_user_signal): Rename from handle_user_signal.
7119 (deliver_interrupt_signal): Rename from interrupt_signal.
7120 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7121 (deliver_child_signal): Rename from sigchld_handler.
7122 * atimer.c (handle_alarm_signal):
7123 * data.c (handle_arith_signal):
7124 * dispnew.c (handle_window_change_signal):
7125 * emacs.c (handle_fatal_signal, handle_danger_signal):
7126 * keyboard.c (handle_input_available_signal):
7127 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7128 * process.c (handle_pipe_signal, handle_child_signal):
7129 New functions, with the actual signal-handling code taken from the
7130 original respective signal handlers, sans the sporadic attempts to
7131 preserve errno, since that's now done by handle_on_main_thread.
7132 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7133 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7134 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7136 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7137 Move initialization of main_thread to sysdep.c's init_signals.
7138 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7139 our usage, and simplifies the mainline code.
7140 (record_child_status_change): New static function, as a helper
7141 for handle_child_signal, and with most of the old child handler's
7143 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7144 (handle_child_signal): Use the above.
7145 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7146 Moved here from emacs.c.
7147 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7148 code moved here from emacs.c's main function.
7149 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7150 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7151 This lets callers save and restore errno properly.
7153 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7155 Remove redundant or unused things here and there.
7156 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7157 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7158 * editfns.c (Fcompare_buffer_substrings): Likewise.
7159 * frame.h (struct terminal, struct font_driver_list):
7160 Remove redundant declarations.
7161 * window.h (Qleft, Qright): Likewise.
7163 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7165 Do not mark objects from deleted buffers, windows and frames.
7166 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7167 (mark_object): Likewise for windows and frames.
7169 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7171 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7172 buffer_defaults and buffer_local_symbols as valid objects.
7173 Return special value to denote them.
7175 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7177 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7178 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7179 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7180 (file_name_absolute_p, Fsubstitute_in_file_name):
7181 (check_executable, check_writable, Ffile_accessible_directory_p)
7182 (Fset_file_selinux_context, Fdefault_file_modes)
7183 (Finsert_file_contents, choose_write_coding_system)
7184 (Fwrite_region, build_annotations, a_write, e_write)
7186 * filelock.c (boot_time_initialized, get_boot_time)
7187 (get_boot_time_1, lock_file_1, within_one_second):
7188 * floatfns.c (in_float):
7189 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7190 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7191 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7192 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7193 * window.c (compare_window_configurations):
7194 Use bool for booleans.
7195 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7196 (Fdefault_file_modes): Now mode_t, not int, for modes.
7197 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7198 (internal_delete_file): Now returns void, not a (boolean) int,
7199 since nobody was looking at the return value.
7200 * lisp.h, window.h: Adjust to above API changes.
7202 * xdisp.c (set_message): Simplify and reindent last change.
7204 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7206 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7208 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7210 * eval.c (call_debugger): Make the function non-static so that we
7211 can call it from set_message.
7213 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7214 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7216 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7218 Give more-useful info on a fatal error (Bug#12328).
7219 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7220 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7221 of doing the work ourselves.
7222 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7223 do most of the work.
7224 (fatal_error_backtrace): New function, taken from the guts
7225 of the old fatal_error_signal, but with a new option to output
7227 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7228 info about the signal than just its number.
7229 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7230 * sysdep.c: Include <execinfo.h>
7231 (emacs_backtrace): New function, taken partly from the previous
7232 code of the 'die' function.
7233 (emacs_abort): Call fatal_error_backtrace rather than abort.
7235 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7237 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7238 eager (load-time) macro-expansion.
7239 * lisp.mk (lisp): Add macroexp.
7241 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7243 Simplify redefinition of 'abort' (Bug#12316).
7244 Do not try to redefine the 'abort' function. Instead, redo
7245 the code so that it calls 'emacs_abort' rather than 'abort'.
7246 This removes the need for the NO_ABORT configure-time macro
7247 and makes it easier to change the abort code to do a backtrace.
7248 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7249 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7250 Remove; sysdep.c's emacs_abort now takes its place.
7251 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7252 'abort' changed to use 'emacs_abort'.
7253 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7254 (abort) [!defined abort]: Rename to ...
7255 (emacs_abort): ... new name.
7256 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7257 the place of the old 'abort' in emacs.c.
7258 * w32.c, w32fns.c (abort): Do not #undef.
7259 * w32.c (emacs_abort): Rename from w32_abort.
7261 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7263 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7264 offsets[j].dv, since the y axis of the screen coordinates points
7265 down, while the y axis of the font definition coordinates points
7266 up. This fixes display of Arabic diacritics such as KASRA and
7267 KASRATAN. (Bug#11860)
7269 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7271 Be more systematic about _setjmp vs setjmp.
7272 * alloc.c (test_setjmp, mark_stack):
7273 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7274 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7275 (png_load, my_error_exit, jpeg_load):
7276 * process.c (send_process_trap, send_process):
7277 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7278 The underscored versions are up to 30x faster on some hosts.
7279 Formerly, the code used setjmp+longjmp sometimes and
7280 _setjmp+_longjmp at other times, with no particular reason to
7281 prefer setjmp+longjmp.
7283 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7285 Fix minor problem found by static checking.
7286 * buffer.c (Fdelete_all_overlays): Return nil.
7288 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7290 * buffer.c (Fdelete_all_overlays): New function.
7292 2012-09-03 Chong Yidong <cyd@gnu.org>
7294 * gtkutil.c: Add extern decl for Qxft.
7296 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7298 * emacs.c, eval.c: Use bool for boolean.
7299 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7300 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7301 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7302 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7303 (main, decode_env_path, Fdaemon_initialized):

7318 * msdos.c (fatal_error_in_progress): ... from here.
7319 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

7322 REDISPLAYING_P when unwinding, instead of saving its previous,
7323 always-false value and then restoring it.
7325 Clean up some extern decls.
7326 Mostly, this hoists extern decls out of .c files and into .h files.
7327 That way, we're more likely to catch errors if the interfaces change.

7413 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7414 more than one grapheme cluster passed to the shaper: compute the
7415 offset adjustment values separately for each cluster. (Bug#11860)
7417 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7418 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7419 about implicit conversions from integer to pointer.
7421 2012-09-01 Daniel Colascione <dancol@dancol.org>
7423 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

7477 window system declarations.
7479 * frame.h: Move common functions here: set_frame_menubar,
7480 x_set_window_size, x_sync, x_get_focus_frame,
7481 x_set_mouse_position, x_set_mouse_pixel_position,
7482 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7513 * term.c (mark_ttys): Remove.
7514 (init_tty): Safely initialize 'top_frame' slot with Qnil.

7543 * lread.c (init_lread): For out-of-tree builds, only add the
7544 source directory's site-lisp dir to the load-path if it exists,
7545 consistent with in-tree builds. (Bug#12302)
7547 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

7568 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7569 Add window_closed and button_values. Add void as return value for
7570 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7571 Add process_dialog as new member.
7573 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7575 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

7753 * data.c (Qinterval): Remove; unused.
7754 (syms_of_data): Do not define 'interval'.
7755 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7756 * window.h (decode_valid_window):
7759 * character.c, charset.c, chartab.c: Use bool for booleans.
7760 * character.c (lisp_string_width, string_count_byte8)
7761 (string_escape_byte8):
7762 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7763 (load_charset_map_from_file, map_charset_chars)
7764 (Fdefine_charset_internal, define_charset_internal)
7765 (Fdeclare_equiv_charset, find_charsets_in_text)
7766 (Ffind_charset_region, char_charset, Fiso_charset):
7767 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7768 (sub_char_table_set, sub_char_table_set_range)
7769 (char_table_set_range, optimize_sub_char_table)
7770 (map_sub_char_table):
7771 Use bool for boolean.
7772 * character.c (str_to_unibyte): Omit last boolean argument; it was
7773 always 0. All callers changed.
7774 * character.h, charset.h: Adjust to match previous changes.
7775 * character.h (char_printable_p): Remove decl of nonexistent function.
7776 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7777 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7778 are all boolean, so make them single-bit bitfields.
7780 * lisp.h (ASET): Remove attempt to detect side effects.
7781 It was meant to be temporary and it often doesn't work,
7782 because when IDX has side effects the behavior of IDX==IDX
7783 is undefined. See Stefan Monnier in
7784 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7786 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7788 * lisp.h (functionp): New function (extracted from Ffunctionp).
7789 (FUNCTIONP): Use it.
7790 * eval.c (Ffunctionp): Use it.
7792 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7794 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7795 as that's faster and simpler than static storage. Don't bother
7796 with the g_main_context_query overhead if g_main_context_pending
7797 says no events are pending.
7798 (gfds, gfds_size): Remove these static vars.
7799 (xgselect_initialize): Remove; no longer needed.
7800 All uses and decls removed.
7802 * emacs.c (fatal_error_signal_hook): Remove.
7803 All uses removed. This leftover from old code was always 0.
7805 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7806 * casefiddle.c (casify_object, casify_region):
7807 * casetab.c (set_case_table):
7808 * category.c, category.h (word_boundary_p):
7809 * category.h (CHAR_HAS_CATEGORY):
7810 Use bool for booleans, instead of int.
7812 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7814 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7816 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7818 On assertion failure, print backtrace if available.
7819 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7820 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7821 * Makefile.in (LIB_EXECINFO): New macro.
7824 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7825 * bytecode.c (exec_byte_code):
7826 * callint.c (check_mark, Fcall_interactively):
7827 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7828 (getenv_internal, sync_process_alive, call_process_exited):
7829 * lisp.h (USE_SAFE_ALLOCA):
7830 Use bool for booleans, instead of int.
7831 * lisp.h, process.h: Adjust prototypes to match above changes.
7832 * callint.c (Fcall_interactively): Don't assume the mark's
7833 offset fits in 'int'.
7835 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7837 * buffer.c, buffer.h: Use bool for boolean.
7838 * buffer.c (reset_buffer_local_variables)
7839 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7840 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7841 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7842 (overlay_touches_p, overlay_strings, Foverlay_put)
7843 (report_overlay_modification, call_overlay_mod_hooks):
7844 (mmap_enlarge, mmap_set_vars):
7845 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7846 Use bool for booleans, instead of int.
7847 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7848 since the 1-or-0 return value is always ignored anyway.
7849 (mmap_initialized_p):
7850 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7851 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7853 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7855 * bidi.c: Use bool for boolean.
7856 This is a bit more readable, and makes the text segment of bidi.o
7857 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7858 Presumably it's faster too.
7859 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7861 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7862 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7863 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7864 (bidi_explicit_dir_char, bidi_level_of_next_char)
7865 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7866 Use bool for booleans, instead of int.
7867 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7868 (bidi_unshelve_cache): Adjust decls to match code.
7870 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7872 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7875 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7877 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7878 * atimer.h: Include <stdbool.h>.
7880 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7882 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7883 compile time tests instead of run time tests on systems that do
7885 (FRAME_MAC_P): Remove leftover from deleted code.
7886 * frame.c (syms_of_frame): Remove leftover from deleted code.
7888 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7890 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7892 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7894 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7895 Otherwise, the compiler complains about (A?B:C) where B is void
7896 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7897 (fontset_add): Return void, for FONTSET_ADD.
7899 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7901 * alloc.c: Use bool for booleans.
7902 (gc_in_progress, abort_on_gc)
7903 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7904 (dont_register_blocks) [GC_MALLOC_CHECK]:
7905 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7906 (check_string_bytes, make_specified_string, memory_full)
7907 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7908 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7909 (mark_stack, valid_pointer_p, make_pure_string)
7910 (Fgarbage_collect, survives_gc_p, gc_sweep):
7911 Use bool for booleans, instead of int.
7912 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7913 Remove unused local.
7914 * alloc.c (PURE_POINTER_P):
7915 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7916 * editfns.c (Fformat):
7917 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7919 * fns.c (sweep_weak_table):
7920 * lisp.h (suppress_checking, push_message, survives_gc_p)
7921 (make_pure_string, gc_in_progress, abort_on_gc):
7922 * lread.c (readchar, read1):
7923 * print.c (Fprin1_to_string):
7924 * xdisp.c (push_message):
7925 Use bool for booleans affected directly or indirectly by
7928 Make recently-introduced setters macros.
7929 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7930 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7931 (set_fontset_default, set_fontset_fallback): Rename from their
7932 upper-case counterparts, and make them functions rather than macros.
7933 This is more consistent with the other recently-introduced setters.
7934 These don't need to be inline, since they're local.
7936 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7938 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7939 the loop (Bug#12247).
7941 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7943 * lisp.h (vcopy): Use memcpy rather than our own loop.
7944 This fixes a performance regression introduced by the recent
7945 addition of vcopy. This means 'vcopy' will need to be modified
7946 for a copying collector, but that's OK. Also, tighten the
7947 checking in the assertion.
7949 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7951 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7952 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7953 non-base glyph for the width of the base character, according to
7954 what x_draw_composite_glyph_string_foreground expects.
7955 Generate WADJUST value according to composition_gstring_width's
7956 expectations, to produce correct width of the composed character.
7957 Reverse the sign of the DU offset produced by ScriptPlace.
7959 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7961 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7963 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7965 Avoid direct writes to contents member of struct Lisp_Vector.
7966 * lisp.h (vcopy): New function to copy data into vector.
7967 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7968 * fns.c (Ffillarray): Use ASET.
7969 * keyboard.c (timer_check_2): Use AREF and ASET.
7970 (append_tool_bar_item, Frecent_keys): Use vcopy.
7971 * lread.c (read_vector): Use ASET.
7972 * msdos.c (Frecent_doskeys): Use vcopy.
7973 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7974 (Finternal_merge_in_global_face): Use ASET and vcopy.
7975 * xfont.c (xfont_list_pattern): Likewise.
7977 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7979 * window.c (Fwindow_point): For the selected window always return
7980 the position of its buffer's point.
7981 (Fset_window_point): For the selected window always go in its
7982 buffer to the specified position.
7984 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7986 Setter macros for fontsets.
7987 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7988 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7989 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7992 2012-08-20 Glenn Morris <rgm@gnu.org>
7994 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7995 Don't assume that `ln -f' works.
7997 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7999 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8000 and later about non-assignments with no effect. See discussion at
8001 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8004 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8006 Inline setter functions for Lisp_Objects slots of struct specbinding.
8007 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8010 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8012 * window.c (select_window): Always make selected window's buffer
8015 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8017 Use AREF and ASET for docstrings of category tables.
8018 * category.h (CATEGORY_DOCSTRING): Use AREF.
8019 (SET_CATEGORY_DOCSTRING): Use ASET.
8020 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8022 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8024 Inline setter functions for hash table members.
8025 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8026 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8027 (set_hash_key_and_value, set_hash_index, set_hash_next)
8028 (set_hash_hash): New functions.
8029 * charset.c, fns.c: Adjust users.
8031 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8033 Inline getter and setter functions for per-buffer values.
8034 * buffer.h (per_buffer_default, set_per_buffer_default)
8035 (per_buffer_value, set_per_buffer_value): New functions.
8036 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8037 * buffer.c, data.c: Adjust users.
8039 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8041 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8043 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8045 Rely on <config.h> + <unistd.h> to declare 'environ',
8046 as gnulib does this if the system doesn't.
8047 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8048 Remove declaration. MS-Windows declares it on stdlib.h which is
8049 included by conf_post.h.
8050 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8051 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8052 * vm-limit.c: Include <unistd.h>, for 'environ'.
8054 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8055 (start_of_data): Remove decl; mem-limits.h provides it.
8057 * xdisp.c (handle_invisible_prop): Make it a bit faster
8058 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8060 2012-08-19 Chong Yidong <cyd@gnu.org>
8062 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8065 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8067 * .gdbinit: Use call instead of set when calling a function in the
8070 * data.c (set_internal): Don't use set_blv_found.
8071 (Fkill_local_variable): Likewise.
8073 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8075 * nsfont.m (ns_ascii_average_width): Ensure the string
8076 ascii_printable is initialized with a null-terminated character
8077 array. Otherwise, it can contain undesired extra characters.
8079 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8081 port new setting code to Sun C 5.8 2005/10/13
8082 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8083 Return void, not Lisp_Object. Otherwise, the compiler
8084 complains about (A?B:C) where B is void and C is Lisp_Object
8085 when compiling CHAR_TABLE_SET, due to the recent change to
8086 the API of sub_char_table_set_contents.
8088 2012-08-18 Chong Yidong <cyd@gnu.org>
8090 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8091 for the string case (Bug#3874).
8093 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8095 * buffer.h (BSET): Remove (Bug#12215).
8096 Replace all uses with calls to new setter functions.

8144 Replace all uses with calls to new setter functions.
8145 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.

8165 New setter functions.
8167 * termhooks.h (TSET): Remove (Bug#12215).
8168 Replace all uses with calls to new setter functions.
8169 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8170 (TERMHOOKS_INLINE): New macro.
8171 (tset_charset_list, tset_selection_alist): New setter functions.
8172 * terminal.c (TERMHOOKS_INLINE):
8173 Define to EXTERN_INLINE, so that the corresponding functions
8174 are compiled into code.
8175 (tset_param_alist): New setter function.
8177 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
8179 * keyboard.h (KSET): Remove (Bug#12215).

8923 value of EMACSLOADPATH, as it is no longer needed.
8924 (check_windows_init_file): Now external, not static.

8930 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8975 * alloc.c (record_xmalloc): New function.
8976 * lisp.h (record_xmalloc): New decl.
8977 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8978 more like a function. This is because the pointer cast is not
8979 needed. All uses changed.
8980 * print.c (print_string, print_error_message): Avoid length recalc.
8982 Improve fix for macroexp crash with debugging (Bug#12118).
8983 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8984 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8985 not supposed to be invoked from the garbage collector.

8987 (gc_aset): New function, which is like ASET but can be
8988 used in the garbage collector.

9017 with addition of handling of symlinks and support for 'lstat'.
9018 If possible, get file's attributes and security information by
9019 handle, not by name. Produce S_IFLNK bit for symlinks, when
9020 called from 'lstat'.
9021 (stat, lstat): New functions, call 'stat_worker'.
9022 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9023 symlinks when the underlying filesystem supports them.
9025 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9027 Fix macroexp crash on Windows with debugging (Bug#12118).
9028 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9029 checking subscripts; problem introduced with the recent
9030 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9031 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9032 since it's used in non-static inline functions now.
9034 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9035 Don't assume buffer size fits in 'int'. Remove unused local.

9526 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9527 arms of an 'if', not using conditional expressions; otherwise GDB
9528 complains about the types in the unevaluated arm when the argument
9529 is an integer literal.
9530 (xgetint): Simplify expression.
9531 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9532 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9533 Zaretskii in <http://bugs.gnu.org/12036#13>.
9534 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9535 needed now that we have gdb_make_enums_visible.
9536 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9537 (enum enum_USE_LSB_TAG):
9538 New enum types, packaging up enums that need to be exported to GDB.
9540 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9542 Utility function to make a list from specified amount of objects.

9556 * xdisp.c (syms_of_xdisp): Likewise.
9557 * xfns.c (syms_of_xfns): Likewise.
9559 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9561 Fast save_excursion_save and save_excursion_restore.
9562 * lisp.h (struct Lisp_Excursion): New data type.
9563 (PVEC_EXCURSION): New pseudovector type.
9564 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9565 to deal with it. Adjust comments.
9566 (init_marker, attach_marker): New prototype.
9567 (unchain_marker): Adjust prototype.
9568 * marker.c (attach_marker): Change to global.

9573 * editfns.c (save_excursion_save, save_excursion_restore):
9574 Reimplement to use struct Lisp_Excursion. Add comments.
9576 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9578 Fix export of symbols to GDB (Bug#12036).
9579 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9580 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9581 emacs.c, as this is a more-suitable home. Had this been done earlier
9582 the fix for 12036 would have avoided some of the problems noted in
9583 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9584 would have been more obvious.
9585 * emacs.c: Do not include <verify.h>; no longer needed.
9586 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9587 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9588 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9589 Remove; now done in lisp.h.
9590 * lisp.h (PUBLISH_TO_GDB): New macro.
9591 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9592 (DATA_SEG_BITS): Use it.
9593 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9594 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9595 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9596 not be usable in #if. This simplifies things.
9598 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9600 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9602 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9604 Simplify export of symbols to GDB (Bug#12036).
9605 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9606 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9607 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9608 Adjust to changes in lisp.h and emacs.c, by using
9609 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9610 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9611 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9612 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9613 instead of gdb_valbits.
9614 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9615 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9616 instead of gdb_array_mark_flag.
9617 (xboolvector): Get size from $->size, not $->header.size.
9618 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9619 (xreload, hook-run, hookpost-run): Remove.
9620 * emacs.c: Include <verify.h>.
9621 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9622 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9624 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9625 (gdb_USE_LSB_TAG): New enum constants.
9626 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9627 Also define these as enum constants, so they're visible to GDB.
9628 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9629 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9630 as constants, so they're visible to GDB.
9631 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9632 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9633 Now enum constants, not macros, so they're visible to GDB.
9634 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9635 more convenient now. All uses changed.
9636 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9637 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9639 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9644 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9646 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9647 add argument, tune behavior, and adjust all callers.
9649 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9651 Use typedef for EMACS_INT, EMACS_UINT.
9652 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9653 than macros. This simplifies debugging in the usual case, since
9654 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9655 and it allows expressions involving EMACS_INT casts.
9656 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9658 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9668 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9670 Adjust buffer text indirection counters at the end of Fkill_buffer.
9671 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9672 buffer is definitely dead. This should really fix an issue reported
9673 by Christoph Scholtes again. (Bug#12007).
9674 (init_buffer_once): Initialize indirection counters of
9675 buffer_defaults and buffer_local_symbols (for sanity and safety).
9677 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9679 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9680 and continuation glyphs on tooltip frames, leave them at zero.
9681 Avoids continued lines in tooltips. (Bug#11832)
9683 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

9695 it signals an error when a tooltip frame is being created.
9697 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9699 Cleanup miscellaneous objects allocation and initialization.

9708 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9710 Swap buffer text indirection counters in Fbuffer_swap_text.
9711 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9712 This avoids crash reported by Christoph Scholtes at
9713 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9715 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9717 * nsmenu.m (Popdown_data): New struct.

9722 and autorelease them. Also autorelease img and matrix (Bug#12005).
9723 (dealloc): Remove (Bug#12005).

9740 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9742 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9743 as it's limited by the amount of memory, not by INT_MAX.
9745 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9747 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9748 in special-event-map. See the discussion at

9807 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9808 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9809 Adjust users accordingly.
9810 * font.h (font_open_by_name): Adjust prototype.
9812 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9829 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9830 'for_each_per_buffer_object_at'.
9831 All uses changed. It's better to use upper-case for macros that
9832 cannot be implemented as functions, to give the reader a clue
9833 that they're special.
9835 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9837 * alloc.c (Fgarbage_collect): Tweak docstring.

9878 * intervals.c (merge_interval_right, merge_interval_left):
9879 Do not zero out this interval if it is absorbed by its children,
9880 as this interval's total length doesn't change in that case. See
9881 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9883 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9885 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9886 when invoking (make-bool-vector N t) and N is a positive

9890 * alloc.c (bool_header_size): New constant.
9891 (header_size, word_size): Move earlier, as they're now used earlier.

9894 padding before the data member of a bool vector.
9895 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9896 than doing the check by hand with an abort ().
9898 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9900 * eval.c (Fdefvar): Don't check constants since we only set the var if
9901 it's not yet defined anyway (bug#11904).
9903 * lisp.h (last_undo_boundary): Declare new var.
9904 * keyboard.c (command_loop_1): Set it.
9905 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9906 were auto-added by the command loop (bug#11774).
9908 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
9910 * w32font.c (Qsymbol): Remove local definition.

10399 2012-07-11 Glenn Morris <rgm@gnu.org>
10401 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
10402 since nothing has defined it on these platforms.
10404 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
10405 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

10413 * s/gnu.h, s/gnu-linux.h:
10414 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
10416 2012-07-11 John Wiegley <johnw@newartisans.com>
10418 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
10419 function attribute, so we only use it if it exists in the
10422 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10424 Avoid call to strlen in fast_c_string_match_ignore_case.
10425 * search.c (fast_c_string_match_ignore_case): Change to use
10426 length argument. Adjust users accordingly.
10427 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10429 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
10431 Assume mkdir, rmdir.

10436 * sysdep.c (rename) [!HAVE_RENAME]: Remove.
10439 * s/hpux10-20.h (HAVE_PERROR): Remove.
10440 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:

10446 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10448 Avoid calls to strlen in font processing functions.
10449 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10450 (font_open_by_name): Change to use length argument.
10451 Adjust users accordingly.
10452 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
10454 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
10455 Change to return ptrdiff_t.
10456 (xfont_list_pattern, xfont_match): Use length returned by
10457 xfont_decode_coding_xlfd.

10463 Move DONT_REOPEN_PTY to configure.
10465 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
10466 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
10468 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10470 Remove "#define unix" that is no longer needed (Bug#11905).
10471 * s/aix4-2.h (unix): Remove; no longer needed.
10473 EMACS_TIME simplification (Bug#11875).
10474 This replaces macros (which typically do not work in GDB)
10475 with functions, typedefs and enums, making the code easier to debug.
10476 The functional style also makes code easier to read and maintain.
10477 * systime.h: Include <sys/time.h> on all hosts, not just if
10478 WINDOWSNT, since 'struct timeval' is needed in general.
10479 (EMACS_TIME): Now a typedef, not a macro.
10480 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10482 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10483 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10487 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10488 which are not functions. All uses rewritten to use:
10489 (make_emacs_time): New function.
10490 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10491 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10492 not functions. All uses rewritten to use the following, respectively:
10493 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10494 (add_emacs_time, sub_emacs_time): New functions.
10495 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10496 * fileio.c (Fcopy_file):
10497 * xterm.c (XTflash): Get the current time closer to when it's used.
10498 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
10500 * bytecode.c (targets): Suppress -Woverride-init warnings.
10502 Simplify by avoiding confusing use of strncpy etc.
10503 * doc.c (Fsnarf_documentation):
10504 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10505 * frame.c (Fmake_terminal_frame):
10506 * gtkutil.c (get_utf8_string):
10508 * nsmenu.m (ns_update_menubar):
10509 * regex.c (regerror):
10510 Prefer memcpy to strncpy and strncat when either will do.
10511 * fileio.c (Fsubstitute_in_file_name):
10512 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10513 (menu_separator_name_p):
10514 * nsmenu.m (ns_update_menubar):
10515 Prefer memcmp to strncmp when either will do.
10516 * nsterm.m: Include <ftoastr.h>.
10518 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10519 Prefer snprintf to strncpy.
10520 * nsterm.m (ns_term_init):
10521 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10522 * nsterm.m (ns_term_init):
10523 Avoid the need for strncpy, by using build_string or
10524 make_unibyte_string directly. Use dtoastr, not snprintf.
10525 * process.c (Fmake_network_process): Diagnose service names that
10526 are too long, rather than silently truncating them or creating
10527 non-null-terminated names.
10528 (Fnetwork_interface_info): Likewise, for interface names.
10529 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10530 Prefer sprintf to strncat.
10531 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10532 Prefer vsnprintf to vsprintf + strncpy.
10534 2012-07-10 Glenn Morris <rgm@gnu.org>
10536 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10537 Clarify fallback case.
10539 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10541 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10542 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10543 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10544 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10545 where argument type is known to be a Lisp_Cons.
10547 2012-07-10 Tom Tromey <tromey@redhat.com>
10549 * bytecode.c (BYTE_CODE_THREADED): New macro.
10550 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10551 (enum byte_code_op): New type.
10552 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10553 (exec_byte_code): Use them. Use token threading when applicable.
10555 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10557 Optimize pure C strings initialization.
10558 * lisp.h (make_pure_string): Fix prototype.
10559 (build_pure_c_string): New function, defined as static inline. This
10560 provides a better opportunity to optimize away calls to strlen when
10561 the function is called with compile-time constant argument.
10562 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10563 argument, adjust users accordingly. Use build_pure_c_string where
10565 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10566 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10567 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10569 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10571 Avoid calls to strlen in miscellaneous functions.
10572 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10573 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10574 * lread.c (openp): Likewise.
10576 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10578 Avoid calls to strlen in path processing functions.
10579 * fileio.c (file_name_as_directory): Add comment. Change to add
10580 srclen argument and return the length of result. Adjust users
10582 (directory_file_name): Fix comment. Change to add srclen argument,
10583 swap 1st and 2nd arguments to obey the common convention.
10584 Adjust users accordingly.
10585 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10587 2012-07-10 Glenn Morris <rgm@gnu.org>
10589 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10590 Move PENDING_OUTPUT_COUNT definition to configure.
10592 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10593 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10594 * s/gnu.h (DATA_START): Move definitions to configure.
10596 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10597 We include usg5-4-common.h, which defines them both.
10599 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10600 O_RDONLY already includes it).
10602 Stop ns builds setting the EMACSLOADPATH environment variable.
10603 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10604 Now it does not set EMACSLOADPATH, just returns the load-path string.
10605 * nsterm.h: Update accordingly.
10606 * lread.c [HAVE_NS]: Include nsterm.h.
10607 (init_lread) [HAVE_NS]: Use ns_load_path.
10608 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10610 2012-07-09 Glenn Morris <rgm@gnu.org>
10612 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10613 since the included bsd-common.h does so.
10615 Stop ns builds setting the EMACSPATH environment variable.
10616 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10617 (ns_init_paths): Do not set EMACSPATH.
10618 * nsterm.h (ns_exec_path): Add it.
10619 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10622 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10624 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10626 * process.c (wait_reading_process_output): 'waitchannels' was unset
10627 when read_kbd || !NILP (wait_for_cell); fix this.
10629 Add GCC-style 'const' attribute to functions that can use it.
10630 * character.h (char_resolve_modifier_mask):
10631 * keyboard.h (make_ctrl_char):
10632 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10633 (init_character_once, next_almost_prime, init_fns, init_image)
10634 (flush_pending_output, init_sound):
10635 * mem-limits.h (start_of_data):
10636 * menu.h (finish_menu_items):
10637 Add ATTRIBUTE_CONST.
10638 * emacs.c (DEFINE_DUMMY_FUNCTION):
10639 Declare the dummy function with ATTRIBUTE_CONST.
10640 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10641 Add decls with ATTRIBUTE_CONST.
10643 Minor improvements to make_formatted_string.
10644 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10645 where int is good enough, as vsprintf returns an int.
10646 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10648 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10650 Use make_formatted_string to avoid double length calculation.
10651 * lisp.h (make_formatted_string): New prototype.
10652 * alloc.c (make_formatted_string): New function.
10653 * buffer.c (Fgenerate_new_buffer_name): Use it.
10654 * dbusbind.c (syms_of_dbusbind): Likewise.
10655 * editfns.c (Fcurrent_time_zone): Likewise.
10656 * filelock.c (get_boot_time): Likewise.
10657 * frame.c (make_terminal_frame, set_term_frame_name)
10658 (x_report_frame_params): Likewise.
10659 * image.c (gs_load): Likewise.
10660 * minibuf.c (get_minibuffer): Likewise.
10661 * msdos.c (dos_set_window_size): Likewise.
10662 * process.c (make_process): Likewise.
10663 * xdisp.c (ensure_echo_area_buffers): Likewise.
10664 * xsettings.c (apply_xft_settings): Likewise.
10666 2012-07-09 Glenn Morris <rgm@gnu.org>
10668 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10669 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10670 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10672 * callproc.c [HAVE_NS]: Include nsterm.h.
10673 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10675 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10677 Move marker debugging code under MARKER_DEBUG.
10678 * marker.c (MARKER_DEBUG): Move marker debugging code under
10679 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10680 for bootstrap with --enable-checking (~3x slowdown reported
10681 by Juanma Barranquero <lekktu@gmail.com>).
10682 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10684 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10686 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10687 See <http://bugs.gnu.org/11825#29>.
10689 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10691 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10692 has no font, use the frame's font. (Bug#11813)
10693 (display_line): Add commentary about displaying truncation glyphs
10695 (produce_special_glyphs): Move here from term.c.
10697 * term.c (produce_special_glyphs): Move to xdisp.c.
10699 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10702 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10704 * xdisp.c (display_line): Avoid warning about implicit declaration
10707 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10709 * lisp.h: Remove empty conditional.
10711 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10713 * lread.c (load_path_check): Now static.
10715 Fix some minor --with-ns problems found by static checking.
10716 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10717 (x_set_font) [!HAVE_X_WINDOWS]:
10718 * image.c (xpm_load_image) [HAVE_NS]:
10719 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10720 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10721 Remove unused local.
10722 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10723 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10724 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10725 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10726 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10727 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10728 Fix pointer signedness problem.
10729 * xfaces.c (FRAME_X_FONT_TABLE):
10730 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10732 2012-07-07 Glenn Morris <rgm@gnu.org>
10734 * lread.c (load_path_check): New function, split from init_lread.
10735 (init_lread): Reorganize. Motivation:
10736 If EMACSLOADPATH is set, check/warn about that rather than the
10737 defaults, which we are not going to use. Hence we can remove
10738 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10739 Don't warn if site-lisp directories are missing.
10740 If not installed, start from a blank load-path, since
10741 PATH_LOADSEARCH refers to the eventual installation directories.
10743 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10745 Support truncation and continuation glyphs on GUI frames, when
10746 fringes are disabled. (Bug#11832)
10747 * xdisp.c (init_iterator): Get dimensions of truncation and
10748 continuation glyphs even if on GUI frames.
10749 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10750 or both, are absent.
10751 (start_display, move_it_in_display_line_to): Handle the case of a
10752 GUI frame without a fringe to display continuation or truncation
10754 (insert_left_trunc_glyphs): Support GUI frames: make sure
10755 truncation glyphs overwrite enough glyphs from the current line to
10756 have sufficient space in pixels.
10757 (display_line): Support truncation and continuation glyphs on GUI
10758 frames. If some spare pixels are left on the line after inserting
10759 the truncation glyphs, fill that space with a stretch glyph of a
10760 suitably computed width.
10762 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10763 produce_glyphs, to support GUI sessions.
10765 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10767 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10769 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10771 Do not require float-time's arg to fit in time_t (Bug#11825).
10772 This works better on hosts where time_t is unsigned, and where
10773 float-time is applied to the (negative) difference between two times.
10774 * editfns.c (decode_time_components): Last arg is now double *,
10775 not int *, and means to store all the result as a double, without
10776 worrying about whether the seconds part fits in time_t.
10777 All callers changed.
10778 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10779 All callers changed.
10780 (Ffloat_time): Do not fail merely because the specified time falls
10781 outside of time_t range.
10783 2012-07-07 Glenn Morris <rgm@gnu.org>
10785 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10786 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10787 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10789 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10791 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10792 Update dependencies.
10794 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10796 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10798 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10799 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10800 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10801 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10802 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10803 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10805 * xfont.c (compare_font_names): Redo to omit the need for casts.
10807 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10809 * xfns.c (Fx_change_window_property): Doc fix.
10810 * w32fns.c (Fx_change_window_property): Doc fix.
10812 * w32fns.c (Fx_window_property): Accept the same arguments as the

10816 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10817 Eli Zaretskii <eliz@gnu.org>
10819 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10820 Windows-specific code from nt/config.nt moved here.
10821 Obsolete settings removed.
10823 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10825 * process.c: Avoid unnecessary calls to gettime.
10826 (wait_reading_process_output): Don't get the time of day
10827 when gobbling data immediately and not waiting, as there's no need
10828 for it in that case. This removes a FIXME.
10830 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10832 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10833 is defined (Bug#11768).
10835 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10837 Fix marker debugging code.
10838 * marker.c (byte_char_debug_check): Do not perform the check
10839 if buffer is not multibyte.
10840 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10841 Call byte_char_debug_check with correct arguments.
10843 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10845 Compile marker debugging code only if ENABLE_CHECKING is defined.
10846 * marker.c (byte_char_debug_check, count_markers):
10847 Use only if ENABLE_CHECKING is defined.
10848 (byte_debug_flag): Remove.
10849 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10850 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10852 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10854 Avoid code repetition in marker-related functions.
10855 * marker.c (attach_marker): New function.
10856 (Fset_marker, set_marker_restricted, set_marker_both)
10857 (set_marker_restricted_both): Use it.
10858 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10859 Consistently rename charno to charpos.
10860 (marker_position): Add eassert.
10861 (marker_byte_position): Convert to eassert.
10863 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

10876 * editfns.c (buildmark): Remove.
10877 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10878 (save_restriction_save): Use build_marker.
10879 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10880 * window.c (save_window_save): Likewise.
10882 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10884 Do not use Fdelete_overlay in delete_all_overlays
10885 to avoid redundant calls to unchain_overlay.
10886 * buffer.c (drop_overlay): New function.
10887 (delete_all_overlays, Fdelete_overlay): Use it.
10888 * minibuf.c (get_minibuffer): Fix comment.
10890 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10892 Port to OpenBSD 5.1 amd64.
10893 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10894 This is needed for OpenBSD, and should be harmless on all BSD systems.
10895 Also, include <sys/sysctl.h>, as it should be available on all
10896 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10897 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10898 use p_pid member, not kp_proc.pid.
10900 2012-07-06 Glenn Morris <rgm@gnu.org>
10902 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10904 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10906 More xmalloc and related cleanup.

10915 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10917 Omit needless casts involving void * pointers and allocation.
10918 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10919 as the former is more robust if P's type is changed.
10920 Prefer xzalloc to xmalloc + memset 0.
10921 Simplify malloc-or-realloc to realloc.
10922 Don't worry about xmalloc returning a null pointer.
10923 Prefer xstrdup to xmalloc + strcpy.
10924 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10926 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10927 alloca of a constant.
10929 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10931 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10932 hscroll is larger than the line width. Fixes long and futile
10933 looping inside extend_face_to_end_of_line (on a TTY) producing
10934 glyphs that are not needed and thrown away.
10936 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10938 * marker.c (set_marker_restricted_both): Simplify by using
10941 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10943 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10945 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10947 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10948 not defined (Bug#11768).
10949 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10950 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10951 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10952 followed by gtk_box_set_homogeneous (Bug#11768).
10953 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10954 (update_theme_scrollbar_width, xg_create_scroll_bar):
10955 Use gtk_scrollbar_new (Bug#11768).
10956 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10957 (is_box_type): New function (Bug#11768).
10958 (xg_tool_item_stale_p): Call is_box_type.
10959 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10960 with default display (Bug#11768).
10962 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10964 * xdisp.c (window_hscroll_limited): New function.
10965 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10966 coordinates when window's hscroll is set to insanely large
10967 values. (Bug#11857)
10969 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11030 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11032 * fileio.c (time_error_value): Check the right error number.
11033 Problem reported by Troels Nielsen in
11034 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11036 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11038 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11039 This should be fixed in a better way; see Eli Zaretskii in
11040 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11041 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11043 * fileio.c (time_error_value): Rename from special_mtime.
11044 The old name's problems were noted by Eli Zaretskii in
11045 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11047 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11048 This variable's comment says Emacs needs at least one GDB-visible
11049 symbol of type enum pvec_type, to work around GDB problems.
11050 The symbol's value doesn't matter.
11052 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11053 that causes compilation to fail on pre-C99 compilers.
11055 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11057 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11071 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11072 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11073 change in pvec_type.
11074 (PSEUDOVECTOR_TYPEP): New macro.
11075 (TYPED_PSEUDOVECTORP): Use it.
11076 * fns.c (internal_equal): Adapt code to extract pvectype.
11077 * emacs.c (gdb_pvec_type): Update type.
11078 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11079 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11080 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11081 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11082 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11083 abusing vector->header.next.nbytes.
11084 (live_vector_p): Use PVEC_TYPE.
11085 (mark_object): Adapt code to extract pvectype. Use switch.
11087 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11089 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11090 Tighten new eassert a bit.
11092 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11094 Fix compilation with --enable-gcc-warnings and -O1
11095 optimization level.
11096 * doprnt.c (doprnt): Change type of tem to int, initialize
11097 to avoid compiler warning. Add eassert.
11098 * search.c (simple_search): Initialize match_byte to avoid
11099 compiler warning. Add eassert.
11101 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11103 Avoid weird behavior with large horizontal scrolls.
11104 Without this change, for example, large hscroll values would
11105 mess up Emacs's display on Fedora 15 x86, presumably due to
11106 overflows in int calculations in the display code.
11107 Also, if buffers had long lines, Emacs would freeze.
11108 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11109 (set_window_hscroll): New function, containing the old guts of
11110 Fset_window_hscroll. Return the clipped value.
11111 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11112 This avoids the need to check against PTRDIFF_MAX.
11114 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11116 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11118 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11120 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11122 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11123 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11124 since GCC 4.4.6 issues a bogus warning for them.
11126 Fix bugs in file timestamp newness comparisons.
11127 * fileio.c (Ffile_newer_than_file_p):
11128 * lread.c (Fload): Use full timestamp resolution of files,
11129 not just the 1-second resolution, so that files that are only
11130 slightly newer still count as newer.
11131 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11132 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11134 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11136 * fileio.c: Improve handling of file time marker. (Bug#11852)

11139 Use it to set special mtime values consistently.
11141 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11143 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11144 marker for non-existing file. (Bug#11852)
11146 2012-07-03 Glenn Morris <rgm@gnu.org>
11148 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11149 and did not make it into globals.h).
11151 2012-07-03 Tom Tromey <tromey@redhat.com>

11197 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11198 values which aren't power of 2.
11199 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11200 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11203 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11205 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11207 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11209 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11211 * alloc.c (allocate_vector_block): Remove redundant
11212 calls to mallopt if DOUG_LEA_MALLOC is defined.
11213 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11214 avoid calls to mallopt if zero_vector is returned.
11216 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11218 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11219 is enabled, avoid dereferencing NULL current_sblock if
11222 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11224 Cleanup basic buffer management.
11225 * buffer.h (struct buffer): Change layout to use generic vector
11226 marking code. Fix some comments. Change type of 'clip_changed'
11227 to bitfield. Remove unused #ifndef old.
11228 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

11235 struct buffer. Fix comment.
11236 (mark_overlay): New function.
11237 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11238 Lisp area of struct buffer.
11239 (mark_object): Use it. Adjust marking of misc objects
11240 and related comments.
11242 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11244 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11245 wrapper that is not needed because the wrapped code is a no-op (zero
11246 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11247 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11249 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11251 * alloc.c (mark_buffer): Simplify. Remove prototype.
11252 (mark_object): Add comment. Reorganize marking of vector-like
11253 objects. Use CHECK_LIVE for all vector-like objects except buffers
11254 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11255 Avoid redundant calls to mark_vectorlike for bool vectors.
11257 2012-06-30 Glenn Morris <rgm@gnu.org>
11259 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11261 * epaths.in (PATH_SITELOADSEARCH): New.
11262 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11263 This is rather than relying on --enable-locallisppath elements
11264 having "site-lisp" in their names. (Bug#10208#25, 11658)
11266 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11268 * w32proc.c (sys_select): Accept and ignore one more argument.
11270 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11272 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11273 (pselect) [!MS_DOS]: Redirect to sys_select.
11275 * sysdep.c: Don't include dos.h and dosfns.h.
11277 * process.c (sys_select):
11278 * msdos.c (sys_select): Accept one more argument and ignore it.
11280 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11281 adapt data types and code to that.
11284 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11285 which clashes with the gnulib function of the same name.
11287 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11289 * font.c (font_style_to_value, font_style_symbolic)
11290 (font_prop_validate_style): Add type checks for values in
11293 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first

11298 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11300 * xdisp.c (try_window_id): Undo last change.
11302 * w32.c (getwd): Adjust commentary about startup_dir.
11303 (init_environment): Always call sys_access, even in non-MSVC
11304 builds. Don't chdir to the directory of the Emacs executable.
11305 This undoes code from 1997 which was justified by the need to
11306 "avoid conflicts when removing and renaming directories". But its
11307 downside was that every relative file name was being interpreted
11308 relative to the directory of the Emacs executable, which can never
11309 be TRT. In particular, it broke sys_access when called with
11310 relative file names.
11311 (sys_access): Map GetLastError to errno.
11313 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11319 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11322 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

11348 Avoid integer overflow on scroll-left and scroll-right.
11349 * window.c (HSCROLL_MAX): New macro.
11350 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11351 overflow when requested scroll falls outside ptrdiff_t range.
11353 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11355 * window.h (struct window): Change type of 'hscroll',
11356 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11357 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11358 Adjust users accordingly.
11359 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11360 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11361 from EMACS_INT to ptrdiff_t.

11380 enabled with --enable-checking=[all,glyphs] configure option.
11381 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11382 adjust comments accordingly.

11437 * alloc.c (allocate_string): Omit intervals initialization.
11438 * alloc.c (make_uninit_multibyte_string): Initialize intervals

11463 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
11464 when building with Clang.

11495 * alloc.c: Remove build_string.

11498 function is called with compile-time constant argument.
11499 * image.c (imagemagick_error): Convert to build_string.

11503 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11505 Use sprintf return value instead of invoking strlen on result.
11506 In the old days this wasn't portable, since some sprintf
11507 implementations returned char *. But they died out years ago and
11508 Emacs already assumes sprintf returns int.
11509 Similarly for float_to_string.
11510 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11516 * xdisp.c (message_dolog):
11517 * xfns.c (syms_of_xfns):
11518 Use sprintf or float_to_string result to avoid need to call strlen.
11519 * data.c (Fnumber_to_string):
11520 Use make_unibyte_string, since the string must be ASCII.
11521 * lisp.h, print.c (float_to_string): Now returns int length.
11522 * term.c (produce_glyphless_glyph):
11523 Use sprintf result rather than recomputing it.
11525 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11526 * Makefile.in (ALL_CFLAGS):
11527 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

11532 * dispextern.h (xstrcasecmp): Define to library function
11533 strcasecmp if available.

11552 sprintf already null-terminates its output.
11554 * xfns.c (x_window): Remove redundant cast.
11556 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11558 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11559 `const char *' to `char *' to avoid compiler warning.
11561 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11563 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11564 instead of truncating it to 63 (admittedly a generous limit).
11566 * process.c: Fix spelling and caps in comments.
11568 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11570 * emacs.c (setpgrp): Remove definition, unused.

11617 Remove unnecessary forward decls.
11619 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11621 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11624 * keyboard.c (kbd_buffer_get_event):
11625 * process.c (Faccept_process_output):
11626 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11627 This improves on the previous patch, which introduced a bug
11628 when time_t is unsigned and as wide as intmax_t.
11629 See <http://bugs.gnu.org/9000#51>.
11631 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11654 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11657 last argument of make_unibyte_string.
11659 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11660 language ID in the event parameters.
11662 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11663 event.code, not the obscure "character set ID".
11665 2012-06-23 Chong Yidong <cyd@gnu.org>
11667 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11681 in the logic of incrementing and decrementing the value of
11682 use_relocatable_buffers.

11696 Support higher-resolution time stamps (Bug#9000).
11697 The time stamps are only nanosecond-resolution at the C level,
11698 since that's the best that any real-world system supports now.
11699 But they are picosecond-resolution at the Lisp level, as that's
11700 easy, and leaves room for future OS improvements.
11702 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11705 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11706 Don't get current time unless it's needed.
11708 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11709 now provides it if it's absent.
11710 (start_atimer): Port to higher-res time stamps.
11711 Check for time stamp overflow. Don't get current time more
11712 often than is needed.
11714 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11715 Include systime.h, not time.h.
11716 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11718 * dired.c: Include stat-time.h.
11719 (Ffile-attributes): File times now have higher resolution.
11721 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11722 (struct image): Timestamp now has higher resolution.
11724 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11725 has at least microseconds now. All uses removed.
11726 (update_frame, update_single_window, update_window, update_frame_1)
11727 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11728 (duration_to_sec_usec): Remove; no longer needed.
11730 * editfns.c (time_overflow): Now extern.
11731 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11732 (float-time, Fformat_time_string, Fcurrent_time_string)
11733 (Fcurrent_time_zone): Accept and generate higher-resolution

11737 (make_time): Now static.
11738 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11739 Report an error if the time is invalid, rather than having the caller
11742 * fileio.c: Include <stat-time.h>
11743 (Fcopy_file): Copy higher-resolution time stamps.
11744 Prefer to set the time stamp via a file descriptor if that works.

11755 (lookup_image): Port to higer-resolution time stamps.
11757 * keyboard.c (start_polling, bind_polling_period):
11758 Check for time stamp overflow.
11759 (read_char, kbd_buffer_get_event, timer_start_idle)
11760 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11761 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11762 Port to higher-resolution time stamps. Do not assume time_t is signed.
11763 (decode_timer): New function. Timers are now vectors of length 9,
11764 not 8, to accommodate the picosecond component.
11765 (timer_check_2): Use it.
11767 * nsterm.m (select_timeout, timeval_subtract): Remove.
11768 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11769 as they're a bit more accurate and handle overflow better.
11770 (ns_select): Change prototype to be compatible with pselect.
11771 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11772 * nsterm.h (ns_select): Adjust prototype.
11774 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

11789 (wait_reading_process_output):
11790 Port to ns-resolution time stamps.
11791 (Faccept_process_output, wait_reading_process_output):
11792 Check for time stamp overflow. Do not assume time_t is signed.
11793 (select_wrapper): Remove; we now use pselect.
11794 (Fprocess_attributes): Now generates ns-resolution time stamps.
11796 * sysdep.c: Include utimens.h. Don't include utime.h
11797 or worry about struct utimbuf; gnulib does that for us now.
11798 (gettimeofday): Remove; gnulib provides a substitute.
11799 (make_timeval): New function.
11800 (set_file_times): Now sets ns-resolution time stamps.
11801 New arg FD; all uses changed.

11804 Now returns ns-resolution time stamp. All uses changed.
11805 Check for time stamp overflow.
11807 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11808 provides a substitute now.
11810 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11811 since it guarantees struct timespec.
11812 (EMACS_TIME): Now struct timespec, so that we can support
11813 ns-resolution time stamps.
11814 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11815 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11816 (EMACS_USECS): Remove.
11817 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11818 so multiply the arg by 1000 before storing it.
11819 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11821 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11828 (make_timeval, make_lisp_time, decode_time_components): New decls.
11829 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11830 that it mishandled time_t overflow. You can't compare by subtracting!
11831 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11832 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11834 * term.c: Include <sys/time.h>.

11839 in the undo buffer.
11840 (Fprimitive_undo): Use them when restoring time stamps.
11842 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11843 (w32_get_internal_run_time):
11844 Port to higher-resolution Emacs time stamps.
11845 (ltime): Now accepts single 64-bit integer, as that's more convenient
11848 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11850 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11851 for compatibility with pselect. Support ns-resolution time stamps.
11853 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11855 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11856 Check for time stamp overflow, and support ns-resolution time stamps.

11859 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11860 (timeval_subtract): Remove; no longer needed.
11861 (XTflash, XTring_bell, x_wait_for_event):
11862 Port to ns-resolution time stamps. Don't assume time_t is signed.

11868 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11870 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11871 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11872 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11873 staticidx goes up to 1597 out of 1600 = 0x640.)
11875 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11877 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11878 Otherwise, the umask might be mistakenly 0 while handling input signals.
11880 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11882 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11889 access to `contents' member of Lisp_Vector objects with AREF and ASET
11892 2012-06-19 Chong Yidong <cyd@gnu.org>
11894 * frame.c (delete_frame): When selecting a frame on a different
11895 text terminal, do not alter the terminal's top-frame.

11899 (unwind_format_mode_line): Restore them.
11900 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11902 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

11911 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11912 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11913 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11914 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11915 (METER_1, METER_2): Simplify.
11917 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11919 * data.c (Fdefalias): Return `symbol' (bug#11686).
11921 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11923 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11924 gets killed during executing of this function (Bug#11665).
11925 Try to always return Qt when the buffer has been actually killed.
11926 (Vkill_buffer_query_functions): In doc-string say that functions
11927 run by this hook should not change the current buffer.
11929 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11931 Fix recently-introduced process.c problems found by static checking.

11949 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11951 * lisp.h (eassert): Assume C89 or later.
11952 This removes the need for CHECK.
11953 (CHECK): Remove. Its comments about always evaluating its
11954 argument were confusing, as 'eassert' typically does not evaluate
11957 * coding.c (produce_chars): Use ptrdiff_t, not int.
11959 * xterm.c (x_draw_underwave): Check for integer overflow.
11960 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12146 as the union type is for debugging, not for production.
12147 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12148 Use an inline function on all platforms when using the union type,
12149 since this is simpler and 'static inline' can be used portably
12151 (LISP_INITIALLY_ZERO): New macro.

12291 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12293 * doprnt.c (doprnt): Truncate multibyte char correctly.
12294 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12295 would mishandle a string argument "Xc" if X was a multibyte
12296 character of length 2: it would truncate after X's first byte
12297 rather than including all of X.
12299 2012-06-06 Chong Yidong <cyd@gnu.org>
12301 * buffer.c (word_wrap): Doc fix.

12348 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12350 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12351 Convert pctcpu and pctmem to Lisp float properly.
12352 Let the compiler fold better, as 100.0/0x8000 is exact.
12354 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12356 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

12366 bitfields where appropriate, remove unused fields.
12367 * window.h (struct window): Remove unused 'last_mark_x' and
12368 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12369 change its type from Lisp_Object to bitfield.
12370 Change type of 'force_start', 'optional_new_start',
12371 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12372 fields from Lisp_Object to bitfield. Adjust users accordingly.
12374 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12376 Pacify gcc -Wdouble-precision when using Xaw.
12377 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12378 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12379 Use 'float' consistently, rather than 'float' in most places
12380 and 'double' in a couple of places.
12382 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12384 * xdisp.c (handle_stop): Detect whether we have overlay strings
12385 loaded by testing it->current.overlay_string_index to be
12386 non-negative, instead of checking whether n_overlay_strings is
12387 positive. (Bug#11587)

12397 * search.c (search_buffer): Remove calls to
12398 r_alloc_inhibit_buffer_relocation, as it is now called by
12399 maybe_unify_char, which was the cause of relocation of buffer text
12402 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12404 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12405 for the duration of call to load_charset, to avoid problems with
12406 callers of maybe_unify_char that access buffer text through C
12409 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12410 decrement the inhibition flag, instead of just setting or
12413 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12415 Remove obsolete '#define static' cruft.
12416 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12417 This #undef was "temporary" in 2000; it is no longer needed
12418 now that '#define static' has gone away.
12419 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12420 (gray_bitmap_bits): Remove; no longer needed.
12421 All uses replaced with definiens.

12429 Define only on platforms that need it.
12430 * emacs.c: Include <sys/gmon.h> when profiling.
12431 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12432 (__executable_start): Remove decl, since lisp.h does it now.
12433 (safe_bcopy): Remove decl; no longer has that name.
12434 (main): Coalesce #if into single bit of code, for simplicity.
12435 Cast pointers to uintptr_t, since standard libraries want integers
12437 * lisp.h (__executable_start): New decl.
12439 2012-05-31 Glenn Morris <rgm@gnu.org>
12441 * image.c (Fimagemagick_types): Doc fix.

12464 Do not create empty overlays with the evaporate property (Bug#9642).
12465 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12466 Bug#9642, but explicitly check that the buffer the overlay would
12467 be moved to is live and rearrange lines to make sure that errors
12468 will not put the overlay in an inconsistent state.
12469 (Fdelete_overlay): Cosmetics.
12471 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12473 * w32term.c (my_bring_window_to_top): New function.
12474 (x_raise_frame): Use handle returned by DeferWindowPos, which
12475 could be different from the original one.

12491 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12493 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12508 Only r_alloc_inhibit_buffer_relocation needed to be added;
12509 the others were already declared.
12511 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12512 before checking whether it's out of range. Put the check inside
12514 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12516 2012-05-27 Ken Brown <kbrown@cornell.edu>

12528 they are now on lisp.h.
12530 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12532 * search.c (search_buffer): Use it to inhibit relocation of buffer
12533 text while re_search_2 is doing its job, because re_search_2 is
12534 passed C pointers to buffer text. (Bug#11519)
12536 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12537 Update value to 24.
12539 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12540 state after an additional call to move_it_in_display_line_to, keep
12541 the values of it->max_ascent and it->max_descent found for the
12543 (pos_visible_p): Revert the comparison against bottom_y to what it
12544 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12547 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12549 Fix coding-related core dumps with gcc -ftrapv.
12550 The code was computing A - B, where A and B are pointers, and B is
12551 random garbage. This can lead to core dumps on platforms that
12552 have special pointer registers, and it also leads to core dumps on
12553 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12554 A - B only when B is initialized properly.
12555 * coding.c (coding_set_source, coding_set_destination): Return void.
12556 (coding_change_source, coding_change_destinations): New functions,

12571 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12573 (initialize_w32_display): Initialize mouse-highlight data.
12575 * w32inevt.c: Include termchar.h and window.h.
12576 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12577 moves, call note_mouse_highlight. If help_echo changed, call
12578 gen_help_event to produce help-echo message in the echo area.
12579 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12582 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12584 * lread.c (read1): Simplify slightly to avoid an overflow warning
12585 with GCC 4.7.0 on x86-64.
12587 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12589 * bidi.c (bidi_mirror_char): Revert last change: an int is

12602 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12604 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12605 (allocate_pseudovector):
12606 Use int, not EMACS_INT, where int is wide enough.
12607 (inhibit_garbage_collection, Fgarbage_collect):
12608 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12609 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where

12628 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12629 (validate_region): Omit unnecessary test for b <= e,
12630 since that's guaranteed by the previous test.
12631 (adjust_overlays_for_delete): Avoid pos + length overflow.
12632 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12633 (report_overlay_modification):
12634 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12635 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12636 Omit pointer cast, which isn't needed anyway, and doesn't work
12637 after the EMACS_INT -> ptrdiff_t change.
12638 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12639 * buffer.h: Adjust decls to match defn changes elsewhere.
12640 (struct buffer_text, struct buffer):
12641 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12642 Use EMACS_INT, not int, where int might not be wide enough.
12643 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12644 not int, to avoid needless 32-bit limit on 64-bit hosts.
12645 (exec_byte_code): Use tighter memory-full test, one that checks
12646 for alloca overflow. Don't compute the address of the object just
12647 before an array, as that's not portable. Use EMACS_INT, not
12648 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12649 * callint.c (Fcall_interactively):
12650 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12651 * callproc.c (call_process_kill, Fcall_process):
12652 Don't assume pid_t fits into an Emacs fixnum.

12662 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12663 (casify_object): Avoid integer overflow when overallocating buffer.
12664 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12665 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12666 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12667 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12668 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12672 For CCL_MapSingle, check that content and value are in int range.

12674 Check that Vcode_version_map_vector is a vector.
12675 (resolve_symbol_ccl_program): Check that vector header is in range.
12676 Always copy the vector, so that we can check its contents reliably
12677 now rather than having to recheck each instruction as it's being
12678 executed. Check that vector words fit in 'int'.
12679 (ccl_get_compiled_code, Fregister_ccl_program)

12686 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

12705 Remove now-unnecessary CHECK_NATNUMs.
12706 (Fdefine_charset_internal): Check ranges here, more carefully.
12707 Don't rely on undefined behavior with signed left shift overflow.
12708 Don't assume unsigned int fits into fixnum, or that fixnum fits
12709 into unsigned int. Don't require max_code to be a valid fixnum;
12710 that's not true for gb10830 4-byte on a 32-bit host. Allow
12711 invalid_code to be a cons, for the same reason. Require code_offset
12712 to be a character. Avoid int overflow if max_char is close
12714 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12715 this is intended anyway and avoids some undefined behavior.
12716 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12717 INDEX_TO_CODE_POINT, as that's what it expects.
12718 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12719 * charset.h (DECODE_CHAR): Return int, not unsigned;
12720 this is what was intended anyway, and it avoids undefined behavior.
12721 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12722 integer-overflow issues.
12723 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12724 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12725 where the argument is EMACS_INT, and this behavior is not intended.
12726 * chartab.c (Fmake_char_table, Fset_char_table_range)
12727 (uniprop_get_decoder, uniprop_get_encoder):
12728 Don't assume fixnum fits in int.
12729 * cmds.c (move_point): New function, that does the gist of
12730 Fforward_char and Fbackward_char, but does so while checking
12731 for integer overflow more accurately.
12732 (Fforward_char, Fbackward_char): Use it.
12733 (Fforward_line, Fend_of_line, internal_self_insert)
12734 (internal_self_insert):
12735 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13382 * xterm.c (x_x_to_emacs_modifiers):
13383 Don't assume EMACS_INT overflows nicely into int.
13384 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
13385 may come from Lisp.

13394 2012-05-25 Glenn Morris <rgm@gnu.org>
13396 * lisp.mk (lisp): Update for more files being compiled now.
13398 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
13400 * lread.c: Remove `read_pure' which makes no difference.
13401 (read_pure): Remove var.
13402 (unreadpure): Remove function.
13403 (readevalloop): Don't call read_list with -1 flag.
13404 (read1, read_vector): Don't test read_pure any more.
13405 (read_list): Simplify.

13416 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
13418 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13421 This directory predates autoconf and is no longer needed nowadays.
13422 Move its few remaining bits of functionality to where they're needed.
13423 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
13424 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

13428 * lisp.h (USE_LSB_TAG):
13429 * mem-limits.h (EXCEEDS_LISP_PTR):
13430 Use VAL_MAX, not VALBITS, in #if.
13431 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13432 (EMACS_UINT): Define unconditionally now.
13433 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13434 (BITS_PER_EMACS_INT): New constants, replacing
13435 what used to be in config.h, but not useful in #if.
13436 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13437 define them any more.
13438 (VAL_MAX): New macro.
13440 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13441 BITS_PER_EMACS_INT, in #if.
13442 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13443 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13444 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
13445 * s/ms-w32.h (DATA_START):
13446 Move here from removed file m/intel386.h.
13447 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13448 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13450 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13452 Assume C89 or later.
13453 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
13454 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
13456 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

13475 2012-05-19 Ken Brown <kbrown@cornell.edu>
13477 * xfns.c (x_in_use): Remove `static' qualifier.
13478 * xterm.h (x_in_use): Declare.
13479 * xgselect.c: Include xterm.h.
13480 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13481 and `display_arg' (bug#9754).
13483 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13485 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13487 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13488 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13490 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13492 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13494 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13495 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13497 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13498 reference to image_cache->refcount.
13499 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13501 2012-05-17 Juri Linkov <juri@jurta.org>
13503 * search.c (Fword_search_regexp, Fword_search_backward)
13504 (Fword_search_forward, Fword_search_backward_lax)
13505 (Fword_search_forward_lax): Move functions to isearch.el
13506 (bug#10145, bug#11381).
13508 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13510 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13512 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13514 * lread.c (init_obarray): Declare Qt and Qnil as special.
13516 2012-05-14 Glenn Morris <rgm@gnu.org>
13518 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13519 Put "libexec" before "bin", for the sake of init_callproc_1.
13521 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13523 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13525 * unexaix.c: Port to more-recent AIX compilers.
13526 (report_error, report_error_1, make_hdr, copy_sym)
13527 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13528 Make arguments const char *, not char *, to avoid violations of C
13529 standard and to fix some AIX warnings reported by Gilles Pion.
13531 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13533 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13534 already have overlays loaded.
13535 (handle_single_display_spec): Before returning without displaying
13536 fringe bitmap, synchronize the bidi iterator with the main display
13537 iterator, by calling iterate_out_of_display_property.
13538 (iterate_out_of_display_property): Detect buffer iteration by
13539 testing that it->string is a Lisp string.
13540 (get_next_display_element): When the current object is exhausted,
13541 and there's something on it->stack, call set_iterator_to_next to
13542 proceed with what's on the stack, instead of returning zero.
13543 (set_iterator_to_next): If called at the end of a Lisp string,
13544 proceed to consider_string_end without incrementing string
13545 position. Don't increment display vector index past the end of
13546 the display vector. (Bug#11417)
13547 (pos_visible_p): Don't report a position visible when move_it_to
13548 stopped at the last line of window, which happens to be scanned
13549 backwards by the bidi iteration. (Bug#11464)
13551 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13553 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13554 and right-margin display specs even if the spec is invalid or we
13555 are on a TTY, and thus unable to display on the fringes.
13556 That's because the text with the property will not be displayed anyway,
13557 so we need to signal to the caller that this is a "replacing"
13558 display spec. This fixes display when the spec is invalid or we
13561 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13563 * unexaix.c (make_hdr): Fix typo in prototype.
13564 This bug broke the build on AIX. Problem reported by Gilles Pion.
13566 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13568 * keyboard.c (kbd_buffer_get_event): Read special events also in
13569 batch mode. (Bug#11415)
13571 2012-05-12 Glenn Morris <rgm@gnu.org>
13573 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13575 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13577 * lisp.mk (lisp): Add newcomment.elc.
13579 2012-05-12 Glenn Morris <rgm@gnu.org>
13581 * Makefile.in (MKDIR_P): New, set by configure.
13582 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13584 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13586 Remove unused function hourglass_started.
13587 * dispextern.h (hourglass_started):
13588 * w32fns.c (hourglass_started):
13589 * xdisp.c (hourglass_started): Remove.
13591 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13593 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13594 Update dependencies.
13596 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13598 * xgselect.c (xg_select): Put maxfds+1 into a var.
13599 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13601 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13603 2012-05-10 Dave Abrahams <dave@boostpro.com>
13605 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13606 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13608 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13610 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13611 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13612 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13613 Initialize xd_registered_buses.
13615 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13617 Untag more efficiently if USE_LSB_TAG.
13618 This is based on a proposal by YAMAMOTO Mitsuharu in
13619 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13620 For an admittedly artificial (nth 8000 longlist) benchmark on
13621 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13622 Emacs's overall text size by 1%.
13623 * lisp.h (XUNTAG): New macro.
13624 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13625 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13626 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13627 * eval.c (Fautoload):
13628 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13629 * frame.h (XFRAME): Use XUNTAG.
13631 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13632 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13633 Remove unportable assumptions about print widths of types like
13635 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13636 intptr_t when converting between pointer and integer, to avoid GCC
13637 warnings about wrong width.
13639 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13641 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13642 stack for each reader_thread, instead of defaulting to 8MB
13643 determined by the linker. This avoids failures in creating
13644 subprocesses on Windows 7, see the discussion in this thread:
13645 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13647 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13649 Fix up display of the *Minibuf-0* buffer in the mini window.
13650 * keyboard.c (read_char): Don't clear the echo area if there's no
13652 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13653 contents of *Minibuf-0*) if there's no message displayed in its stead.
13655 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13657 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13660 2012-05-06 Chong Yidong <cyd@gnu.org>
13662 * lisp.mk (lisp): Update.
13664 2012-05-05 Jim Meyering <meyering@redhat.com>
13666 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13668 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13670 * data.c (PUT_ERROR): New macro.
13671 (syms_of_data): Use it. Add new error type `user-error'.
13672 * undo.c (user_error): New function.
13673 (Fprimitive_undo): Use it.
13674 * print.c (print_error_message): Adjust print style for `user-error'.
13675 * keyboard.c (user_error): New function.
13676 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13678 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13680 Do not limit current-time-string to years 1000..9999.
13681 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13682 (Fcurrent_time_string): Support any year that is supported by the
13683 underlying localtime representation. Don't use asctime, as it
13684 has undefined behavior for years outside the range -999..9999.
13686 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13688 Fix race conditions involving setenv, gmtime, localtime, asctime.
13689 Without this fix, interrupts could mess up code that uses these
13690 nonreentrant functions, since setting TZ invalidates existing
13691 tm_zone or tzname values, and since most of these functions return
13692 pointers to static storage.
13693 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13694 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13695 Grow the critical sections to include not just invoking
13696 localtime/gmtime, but also accessing these functions' results
13697 including their tm_zone values if any, and any related TZ setting.
13698 (format_time_string): Last arg is now struct tm *, not struct tm **,
13699 so that the struct tm is saved in the critical section.
13700 All callers changed. Simplify allocation of initial buffer, partly
13701 motivated by the fact that memory allocation needs to be outside
13702 the critical section.
13704 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13706 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13707 with RESET_INTERVAL.

13718 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13720 * xdisp.c (pos_visible_p): If already at a newline from the
13721 display string before the 'while' loop, don't walk back the glyphs
13722 from it3.glyph_row. Solves assertion violation when the display
13723 string begins with a newline (egg.el). (Bug#11367)
13725 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13727 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

13733 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13734 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13735 All were removed before 23.1.
13737 * dispnew.c: Remove HAVE_LIBNCURSES test;
13738 it is always true on relevant platforms.
13740 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13741 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

13748 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13751 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13753 Do not avoid creating empty evaporating overlays (Bug#9642).
13754 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13755 That is, do not delete an evaporating overlay if it becomes
13756 empty after its bounds are adjusted to fit within its buffer.
13757 This fix caused other problems, and I'm reverting it until we get
13758 to the bottom of them.
13760 2012-04-27 Chong Yidong <cyd@gnu.org>
13762 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13764 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13766 * xdisp.c (pos_visible_p): If the window start position is beyond
13767 ZV, start the display from buffer beginning. Prevents assertion
13768 violation in init_iterator when the minibuffer window is scrolled
13769 via the scroll bar.
13771 * window.c (window_scroll_pixel_based): Likewise.
13773 2012-04-27 Chong Yidong <cyd@gnu.org>
13775 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13777 2012-04-27 Glenn Morris <rgm@gnu.org>
13779 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13780 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13782 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13784 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13785 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13787 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13789 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13790 display element, check also the underlying string or buffer
13791 character. (Bug#11341)
13793 * w32menu.c: Include w32heap.h.
13794 (add_menu_item): If the call to AppendMenuW (via
13795 unicode_append_menu) fails, disable Unicode menus only if we are
13796 running on Windows 9X/Me.
13798 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13800 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13801 (xgetint): Add missing shift for LSB tags.
13803 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13805 * keyboard.c (read_char): Don't wipe echo area for select window
13806 events: These might get delayed via `mouse-autoselect-window'
13809 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13811 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13812 manipulation of :loaded-from data.
13814 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13816 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13817 now a cons (bug#11311).
13819 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13821 Do not create empty overlays with the evaporate property (Bug#9642).
13822 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13823 if it becomes empty after its bounds are adjusted to fit within
13824 its buffer. Without this fix, in a nonempty buffer (let ((o
13825 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13826 yields an empty overlay that has the evaporate property, which is
13827 not supposed to happen.
13829 Fix minor GTK3 problems found by static checking.
13830 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13849 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13850 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13851 (__malloc_size_t, __malloc_ptrdiff_t):
13852 Remove. All uses removed, replaced by the definiens if needed,
13853 since we can assume C89 or better now.
13854 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13862 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13863 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13864 Define using prototypes, not old style.

13872 (valloc): Use getpagesize, not __getpagesize.
13873 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

13929 * alloc.c: Handle unusual debugging option combinations.
13930 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13931 since the two debugging options are incompatible.
13932 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

13942 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13944 * sysdep.c [__FreeBSD__]: Minor cleanups.
13945 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13946 Use Emacs indenting style more consistently. Avoid some casts.
13947 Use 'double' consistently rather than mixing 'float' and 'double'.
13949 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13951 * sysdep.c (list_system_processes, system_process_attributes):

13958 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13960 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13961 It is never used otherwise.
13963 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13965 * print.c (print_preprocess): Only check print_depth if print-circle
13967 (print_object): Check for cycles even when print-circle is nil and
13968 print-gensym is t, but only check print_depth if print-circle is nil.
13970 2012-04-20 Chong Yidong <cyd@gnu.org>
13972 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13973 set the status to "failed" and ensure that sentinel is run.
13975 2012-04-20 Glenn Morris <rgm@gnu.org>
13977 * process.c (Fset_process_inherit_coding_system_flag)

13988 farther than the first row after the header line, if any.
13989 Don't consider the header-line row as "partially visible", even if

14030 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14031 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14032 (NEED_MEM_INSERT): New macro.
14033 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14034 Remove one incorrect comment and fix another.

14039 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
14040 (r_alloc_sbrk): Now static.
14042 Improve ralloc.c interface checking.
14043 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14044 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

14070 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14071 * s/netbsd.h, s/sol2-6.h:
14072 Remove definition of GC_MARK_STACK, since the default now works.
14073 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14074 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14075 no longer the default.
14076 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14078 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14080 * lread.c (lisp_file_lexically_bound_p):

14101 2012-04-11 Daniel Colascione <dancol@dancol.org>
14103 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14104 against is gone. It's better to use vfork now so that when Cygwin
14105 gains a new, working vfork, we use it automatically (bug#10398).
14107 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14127 * w32.c (w32_delayed_load): Record the full path of the library
14128 being loaded (bug#10424).
14130 2012-04-09 Glenn Morris <rgm@gnu.org>
14132 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14133 not just in the obarray, before snarfing them. (Bug#11036)
14135 * Makefile.in ($(leimdir)/leim-list.el):
14136 Pass EMACS rather than BUILT_EMACS.
14138 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14140 * process.c (make_process):
14141 * process.h: Add integer `gnutls_handshakes_tried' member to
14144 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
14145 Add convenience `GNUTLS_LOG2i' macro.
14147 * gnutls.c (gnutls_log_function2i): Convenience log function.
14148 (emacs_gnutls_read): Use new log functions,
14149 `gnutls_handshakes_tried' process member, and
14150 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14151 attempts per process (connection).
14153 2012-04-09 Chong Yidong <cyd@gnu.org>
14155 * eval.c (Fuser_variable_p, user_variable_p_eh)

14160 * minibuf.c (Fread_variable): Callers changed.
14162 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14164 * xdisp.c (set_cursor_from_row): If the display string appears in
14165 the buffer at position that is closer to point than the position
14166 after the display string, display the cursor on the first glyph of
14167 the display string. Fixes cursor display when a 'display' text
14168 property immediately follows invisible text. (Bug#11094)
14170 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14172 composite.c: use 'double' consistently
14173 * composite.c (get_composition_id): Use 'double' consistently
14174 instead of converting 'float' to 'double' and vice versa; this is
14175 easier to understand and avoids a GCC warning.
14177 2012-04-09 Glenn Morris <rgm@gnu.org>
14179 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14180 preparation for dumping it with emacs. (Bug#4789)
14181 (leimdir): New variable.
14182 ($(leimdir)/leim-list.el): New rule.
14183 (emacs$(EXEEXT)): Depend on leim-list.el.
14185 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)

14197 Remove unused local variable.
14199 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14201 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14202 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14203 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14204 objects, as mark_maybe_pointer will catch them otherwise.
14205 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14206 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
14208 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14210 Fix typo that broke non-Windows builds.
14211 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
14213 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14215 Support building on MS-Windows with libxml2.
14217 * makefile.w32-in (OBJ2): Add xml.$(O).
14218 (GLOBAL_SOURCES): Add xml.c.
14219 ($(BLD)/xml.$(O)): New dependency list.
14221 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14222 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14223 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14224 [!WINDOWSNT]: New macros.
14225 (init_libxml2_functions, libxml2_loaded_p): New functions.
14226 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14227 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14228 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14229 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14231 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14232 Call init_libxml2_functions before calling libxml2 functions.
14233 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14235 * emacs.c: Don't include libxml/parser.h.
14236 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14237 xmlCleanupParser directly.
14239 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14241 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14243 * indent.c (Fvertical_motion): If there is a display string at
14244 point, use it.vpos to compute how many lines to backtrack after
14245 move_it_to point. (Bug#11133)
14247 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14249 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14250 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14251 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14252 macros related to unification of CJK characters. For the details,
14253 see the discussion following the message here:
14254 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14256 2012-04-04 Chong Yidong <cyd@gnu.org>
14258 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14260 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14262 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14263 instead of alloca. (Bug#11138)
14265 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14267 * w32menu.c (is_simple_dialog): Properly check lisp types.
14270 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14272 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14273 position we get to after a call to move_it_to fails the
14274 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14275 only if we wind up in a string from display property. (Bug#11063)
14277 * window.c (Fdelete_other_windows_internal): Invalidate the row
14278 and column information about mouse highlight, so that redisplay
14279 restores it after reallocating the glyph matrices. (Bug#7464)
14281 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14282 string comes from a `display' text property, use the buffer
14283 position of that property as if we actually saw that position in
14285 (move_it_by_lines): Remove the assertion that
14286 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14287 violated when there's a before-string at the beginning of a line.
14290 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14292 * xdisp.c (append_space_for_newline): If the default face was
14293 remapped, use the remapped face for the appended newline.
14294 (extend_face_to_end_of_line): Use the remapped default face for
14295 extending the face to the end of the line.
14296 (display_line): Call extend_face_to_end_of_line when the default
14297 face was remapped. (Bug#11068)
14299 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14301 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14303 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14305 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14307 2012-03-27 Glenn Morris <rgm@gnu.org>
14309 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14312 2012-03-26 Kenichi Handa <handa@m17n.org>
14314 * dispextern.h (struct glyph): Fix previous change. Change the
14315 bit length of glyphless.ch to 25 (Bug#11082).
14317 2012-03-26 Chong Yidong <cyd@gnu.org>
14319 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14320 (command_loop_1): Use it; inhibit selection update for
14321 handle-select-window too (Bug#8996).
14323 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14325 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14327 2012-03-25 Kenichi Handa <handa@m17n.org>
14329 * dispextern.h (struct glyph): Change the bit length of
14330 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14332 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14334 * s/ms-w32.h (tzname): Include time.h before redirecting to
14335 _tzname. Fixes the MSVC build. (Bug#9960)
14337 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14339 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14342 * xterm.c (XTread_socket): Only modify handling_signal if
14343 !SYNC_INPUT. (Bug#11080)
14345 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14347 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14348 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14349 when fetching a multibyte character consumes more bytes than
14350 CHAR_BYTES returns, due to unification of CJK characters in
14351 string_char. (Bug#11073)
14353 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14355 * process.c (wait_reading_process_output): Handle pty disconnect
14356 by refraining from sending oneself a SIGCHLD (bug#10933).
14358 2012-03-22 Chong Yidong <cyd@gnu.org>

14363 Mark string as coming from a prefix property.
14364 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14365 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14367 2012-03-21 Chong Yidong <cyd@gnu.org>
14369 * xfaces.c (Vface_remapping_alist): Doc fix.
14371 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14373 * w32proc.c (Fw32_set_console_codepage)
14374 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
14377 2012-03-20 Chong Yidong <cyd@gnu.org>
14379 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14380 to reflect default non-nil value of redisplay-dont-pause.
14382 2012-03-19 Kenichi Handa <handa@m17n.org>
14384 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14385 it fit in a valid range (Bug#11003).
14387 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14389 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14390 that is not from display property, accept the row as a "cursor
14391 row" if one of the string's character has a non-nil `cursor'
14392 property. Fixes cursor positioning when there are newlines in
14393 overlay strings, e.g. in icomplete.el. (Bug#11035)
14395 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14397 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14399 2012-03-12 Chong Yidong <cyd@gnu.org>
14401 * eval.c (inhibit_lisp_code): Rename from
14402 inhibit_window_configuration_change_hook; move from window.c.
14404 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14405 * window.c (run_window_configuration_change_hook)
14406 (syms_of_window): Callers changed.
14408 2012-03-11 Chong Yidong <cyd@gnu.org>
14410 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14412 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14414 2012-03-10 Chong Yidong <cyd@gnu.org>
14416 * frame.c (other_visible_frames): Don't assume the selected frame
14417 is visible (Bug#10955).
14419 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14421 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14423 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14425 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14426 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14429 2012-03-03 Glenn Morris <rgm@gnu.org>
14431 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14433 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14435 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14436 position past the first glyph_row that ends at ZV. (Bug#10902)
14437 (redisplay_window, next_element_from_string): Fix typos in
14439 (redisplay_window): Pass to move_it_vertically the margin in
14440 pixels, not in screen lines.
14442 2012-03-02 Glenn Morris <rgm@gnu.org>
14444 * buffer.c (buffer-list-update-hook): Doc fix.
14446 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14448 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14449 push_it before setting up the iterator for the first overlay
14450 string, even if we have an empty string loaded.
14451 (next_overlay_string): If there's an empty string on the iterator
14452 stack, pop the stack. (Bug#10903)
14454 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14456 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14457 Suggested by Stefan Monnier in
14458 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14459 * alloc.c (widen_to_Lisp_Object): New static function.
14460 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14461 and widening them to Lisp_Objects. This would work even if
14462 USE_LSB_TAG is defined and wide integers are used, which might
14463 happen in a future version of Emacs.
14465 2012-02-25 Chong Yidong <cyd@gnu.org>
14467 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14470 * xselect.c (Fx_selection_exists_p): Doc fix.
14471 (x_clipboard_manager_save_all): Print an informative message
14472 before saving to clipboard manager.
14474 2012-02-24 Chong Yidong <cyd@gnu.org>
14476 * keyboard.c (process_special_events): Handle all X selection
14477 requests in kbd_buffer, not just the next one (Bug#8869).
14479 2012-02-23 Chong Yidong <cyd@gnu.org>
14481 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14482 call when setting menu-bar-lines and tool-bar-lines parameters.
14483 (unwind_create_frame_1): New helper function.
14485 * window.c (inhibit_window_configuration_change_hook): New var.
14486 (run_window_configuration_change_hook): Obey it.

14504 when computing $valmask.
14506 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14507 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14508 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14509 It's useless in that case, and it can cause problems on hosts
14510 that allocate halves of EMACS_INT values separately.
14511 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14512 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14513 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14514 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14515 it avoids undefined behavior on hosts where shifting right by more
14516 than the word width has undefined behavior.
14518 2012-02-19 Chong Yidong <cyd@gnu.org>
14520 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14521 (Funhandled_file_name_directory, Ffile_name_as_directory)
14522 (Fdirectory_file_name, Fexpand_file_name)
14523 (Fsubstitute_in_file_name): Protect against invalid file handler
14524 return values (Bug#10845).
14526 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14528 * .gdbinit (pitx): Fix incorrect references to fields of the

14535 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14537 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14538 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14540 2012-02-15 Chong Yidong <cyd@gnu.org>
14542 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14543 marked as special. Also, starting docstrings with * is obsolete.
14545 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14547 * gnutls.c (emacs_gnutls_write): Fix last change.

14556 * keymap.c (Fsingle_key_description): Handle char ranges.
14558 2012-02-12 Chong Yidong <cyd@gnu.org>
14560 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14561 as that creates a dangerous corner case.
14563 * window.c (Fdelete_window_internal): Invalidate the mouse
14564 highlight (Bug#9904).
14566 2012-02-12 Glenn Morris <rgm@gnu.org>
14568 * xselect.c (Fx_own_selection_internal)
14569 (Fx_get_selection_internal, Fx_disown_selection_internal)
14570 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14571 * nsselect.m (Fx_own_selection_internal)
14572 (Fx_disown_selection_internal, Fx_selection_exists_p)
14573 (Fx_selection_owner_p, Fx_get_selection_internal):
14574 Sync docs and argument specs with the xselect.c versions.
14576 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14578 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14580 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14582 * w32select.c (Fx_selection_exists_p): Sync doc string and
14583 argument list with xselect.c. (Bug#10783)
14585 * w16select.c (Fx_selection_exists_p): Sync doc string and
14586 argument list with xselect.c. (Bug#10783)

14596 2012-02-07 Chong Yidong <cyd@gnu.org>
14598 * buffer.c (Fbuffer_local_variables)
14599 (buffer_lisp_local_variables): Handle unbound vars correctly;
14600 don't let Qunbound leak into Lisp.
14602 2012-02-07 Glenn Morris <rgm@gnu.org>

15133 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15134 verifies glyph row's hash code--we have just reallocated the
15135 glyphs, so their contents can be complete garbage. (Bug#10164)

15181 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
15182 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
15183 this macro definition.

15214 (start_display): Don't move to the next line if the display should
15215 start at a newline that is part of a display vector or an overlay
15216 string. (Bug#10119)

15295 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15296 Otherwise, valgrind does not work on some platforms.
15297 Problem reported by Andreas Schwab in
15298 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15299 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15300 is set, removing the need for VIRT_ADDRESS_VARIES.
15301 (PURE_P): Use a more-efficient implementation that needs just one
15302 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15303 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15304 to 4 (xorl, subq, cmpq, setbe).
15305 * alloc.c (pure): Always extern now, since that's the
15306 VIRT_ADDR_VARIES behavior.
15307 (PURE_POINTER_P): Use a single comparison, not two, for
15308 consistency with the new puresize.h.
15309 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15310 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15316 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15317 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15318 behave as if the cursor position were at the window margin.
15320 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15321 and the cursor position is out of bounds, behave as if the cursor
15322 position were at the window margin. (Bug#10075)
15324 2011-11-18 Chong Yidong <cyd@gnu.org>
15326 * window.c (Fwindow_combination_limit): Make first argument

15345 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
15347 * xdisp.c (row_hash): New function, body extracted from
15348 compute_line_metrics.
15349 (compute_line_metrics): Call row_hash, instead of computing the
15352 * dispnew.c (verify_row_hash): Call row_hash for computing the
15353 hash code of a row, instead of duplicating code from xdisp.c.
15355 * dispextern.h (row_hash): Add prototype.
15357 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15359 * frame.c (delete_frame): Don't delete the terminal when the last

15385 (Fsplit_window_internal, saved_window)
15386 (Fset_window_configuration, save_window_save): Rename all
15387 occurrences of window_nest to window_combination_limit.

15393 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15395 * xdisp.c (display_line): Move the call to
15396 highlight_trailing_whitespace before the call to
15397 compute_line_metrics, since the latter needs to see the final
15398 faces of all the glyphs to compute ROW's hash value.
15399 Fixes assertion violations in row_equal_p. (Bug#10035)
15401 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
15403 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

15408 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15409 with user-defined heap size. Bump the default size of the temacs
15410 heap to 27MB, to avoid memory warning when running temacs.

15413 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15414 current_matrix and desired_matrix. (Bug#9990)
15415 (verify_row_hash) [XASSERTS]: New function.
15416 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

15460 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15462 Avoid some portability problems by eschewing 'extern inline' functions.
15463 The trivial performance wins aren't worth the portability hassles; see
15464 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15466 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15541 (window_box_right, window_box_right_offset): Declare extern.
15542 Otherwise, these inline functions do not conform to C99 and
15543 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15544 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15545 * intervals.c (adjust_intervals_for_insertion)
15546 (adjust_intervals_for_deletion): Now extern, because otherwise the

15548 (static_offset_intervals): Remove.
15549 (offset_intervals): Rewrite using the old contents of
15550 static_offset_intervals. The old version didn't conform to C99
15551 because an extern inline function contained a reference to an
15552 identifier with static linkage.

15787 (w32font_open_internal, compute_metrics):
15788 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15789 instead of calling the "wide" APIs directly.

15799 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

15802 2011-10-27 Chong Yidong <cyd@gnu.org>
15804 * process.c (make_process): Set gnutls_state to NULL.
15806 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15807 non-NULL, regardless of GNUTLS_INITSTAGE.

15856 (bidi_resolve_weak): Don't enter the expensive loop if the current
15857 position is before next_en_pos. Record the bidi type of the first
15858 non-ET, non-BN character we find, in addition to its position.
15859 (bidi_level_of_next_char): Invalidate next_en_type when
15860 next_en_pos is over-stepped.
15862 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15864 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15865 * editfns.c: Rewrite current-time-zone so that it invokes
15866 the equivalent of (format-time-string "%Z") to get the time zone name.
15867 This fixes a bug when the time zone name contains characters that
15868 need converting from the system time locale to Emacs internal format.
15869 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15870 that patch fixed format-time-string to do the conversion, but
15871 I forgot to fix current-time-zone.
15872 (format_time_string): New function, containing most of
15873 what Fformat_time_string used to contain.
15874 (Fformat_time_string): Rewrite in terms of format_time_string.
15875 This doesn't change this function's behavior.
15876 (current-time-zone): Rewrite to use format_time_string.
15877 This fixes the bug reported by Michael Schierl in
15878 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15879 Jason Rumney's 2007-06-07 change worked around this bug, but
15881 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15883 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15885 * xdisp.c (start_display): If the character at POS is displayed
15886 via a display vector, reset IT->current.dpvec_index to zero.
15887 (try_window_reusing_current_matrix): If a line ends in a display
15888 vector or the next line starts in a display vector, continue
15889 redrawing the window even though the character position of
15890 start_row was reached.
15893 2011-10-18 Chong Yidong <cyd@gnu.org>
15895 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15896 with nobreak-char-display too.
15898 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15900 Fix part 3 of bug#9771.
15901 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15902 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15903 non-neutral characters if the current character is a paragraph
15904 separator (a.k.a. Newline). This avoids running the same
15905 expensive loop twice, once when we consume the preceding newline
15906 and the other time when the line actually needs to be displayed.
15907 Avoid the loop when we see neutrals on the base embedding level
15908 following a character whose directionality is the same as the
15909 paragraph's. This avoids running the expensive loop when a line
15910 ends in a long sequence of neutrals, like control characters.
15911 Add assertion against STRONG_AL type. Slightly rearrange code
15912 that determines the type of a neutral given the first non-neutral
15914 (bidi_level_of_next_char): Set next_en_pos to zero when
15915 invalidating its info.
15917 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15919 * xdisp.c (push_display_prop): Determine whether to record string
15920 or buffer position by IT->string, not by IT->method. Allow
15921 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15922 (move_it_vertically_backward): Don't look for character position
15923 immediately after the newline when in a continuation line.
15926 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15928 * window.c (coordinates_in_window): Rewrite and delabelize
15929 vertical border check. (Bug#5357) (Bug#9618)
15931 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15933 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15934 errors in XSetWindowBorder (bug#9310).
15936 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15938 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15939 avoid crash when xmalloc overrun checking is enabled.
15941 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15943 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15944 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15945 cursor motion with <left> and <right> arrow keys.
15947 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15948 some callers set that themselves.
15950 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15952 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15953 display string and the previous row comes from the same string and
15954 is empty. (Bug#9739) (Bug#9738)
15956 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15958 * doc.c (get_doc_string): Encode file name (bug#9735).
15960 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15962 * bidi.c (bidi_level_of_next_char):
15963 * xdisp.c (get_visually_first_element): Remove old incorrect
15964 comments regarding the Unicode Line Separator character.
15966 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15968 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

15971 boundary if nzombies > MAX_ZOMBIES.

15974 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15976 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15977 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15979 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15980 Some packages use them to denote characters with modifiers.
15982 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15984 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15985 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15986 matching a pp-number. Rename parameter var to var1.
15988 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15990 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).

15994 * callint.c (Fcall_interactively): Give a more explicit error for the
15995 'c' case with a non-character input. (Bug#8479)

15999 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16001 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16002 lines that are hscrolled on the left.
16004 * dispnew.c (buffer_posn_from_coords): Account for a possible
16005 presence of header-line. (Bug#4426)
16007 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16009 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16010 Don't advertise functionality which we discourage or doesn't work.
16012 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16014 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16015 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16016 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16017 this makes Emacs dump core during garbage collection on rare
16018 occasions. sizeof is obviously inferior to offsetof here, so
16019 stick with offsetof.
16020 (GC_POINTER_ALIGNMENT): New macro.
16021 (mark_memory): Omit 3rd (offset) arg; caller changed.
16022 Don't assume EMACS_INT alignment is the same as pointer alignment.
16024 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16026 * keyboard.c (read_key_sequence_remapped): New var.
16027 (read_key_sequence): Compute remapping in the right buffer.
16028 (command_loop_1): Use read_key_sequence's remapping directly.
16030 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16032 * dired.c (file_name_completion): Don't expand file name.
16033 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16034 before checking file name handler.
16036 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16037 they've been requested explicitly (bug#9591).
16039 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16041 * keymap.c (Fsingle_key_description): Use make_specified_string
16042 instead of build_string to build string from push_key_description.
16045 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16047 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16048 This fixes a Y2038 bug on 64-bit hosts.
16049 * buffer.c (reset_buffer):
16050 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16051 (Fclear_buffer_auto_save_failure):
16052 Use 0, not -1, to represent an unset failure time, since time_t
16053 might not be signed.
16055 Remove dependency on glibc malloc internals.
16056 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16057 Move back here from lisp.h, but with their new implementations.
16058 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16059 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16060 * charset.c (charset_table_init): New static var.
16061 (syms_of_charset): Use it instead of xmalloc. This removes a
16062 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16063 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16064 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16065 Move back to alloc.c.
16066 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16067 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16069 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16071 * nsterm.m (windowDidResize): Call x_set_window_size only when
16072 ns_in_resize is true. Otherwise set pixelwidth/height and
16073 call change_frame_size (Bug#9628).
16075 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16077 Port --enable-checking=all to Fedora 14 x86-64.
16078 * charset.c (syms_of_charset): Also account for glibc malloc's
16079 internal overhead when calculating the initial malloc maximum.
16081 Port --enable-checking=all to Fedora 14 x86.
16082 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16084 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16085 (overrun_check_realloc, overrun_check_free):
16086 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16087 That way, xmalloc returns a properly-aligned pointer even if
16088 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16089 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16090 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16091 into account when calculating the initial malloc maximum.
16092 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16093 Move here from alloc.c, so that charset.c can use it too.
16094 Properly align; the old code wasn't right for common 32-bit hosts
16095 when configured with --enable-checking=all.
16096 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16097 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16099 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16101 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16104 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16106 * xdisp.c (compute_display_string_end): If there's no display
16107 string at CHARPOS, return -1.
16109 * bidi.c (bidi_fetch_char): When compute_display_string_end
16110 returns a negative value, treat the character as a normal
16111 character not covered by a display string. (Bug#9624)
16113 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16115 * lread.c (Fread_from_string): Fix typo in docstring.
16117 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16119 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16120 newline, reseat the iterator instead of bidi-iterating there one
16121 character at a time. (Bug#9610)
16122 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16123 TO_CHARPOS if the bidi iterator is at base embedding level.
16125 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16127 * lread.c (readevalloop): Use correct code for NBSP.
16128 (read1): Likewise. (Bug#9608)
16130 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16132 * dbusbind.c (Fdbus_register_signal): When service is not
16133 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16135 2011-09-25 Glenn Morris <rgm@gnu.org>
16137 * buffer.c (truncate-lines): Doc fix.
16139 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16141 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16142 (Fset_window_next_buffers): Doc fix.
16144 2011-09-24 Glenn Morris <rgm@gnu.org>
16146 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16148 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16150 Fix minor problems found by static checking.
16151 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16152 * indent.c (Fvertical_motion): Fix == vs = typo.
16154 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16156 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16157 Default value is now t. Doc fix.
16159 * indent.c (Fvertical_motion): Compute and apply the overshoot
16160 logic when moving up, not only when moving down. Fix the
16161 confusing name and values of the it_overshoot_expected variable;
16162 logic changes accordingly. (Bug#9254) (Bug#9549)
16164 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16165 CHARPOS is covered by a display string which includes newlines.
16166 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16167 is covered by a display string with embedded newlines.
16169 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16171 * dbusbind.c (Fdbus_register_signal): Add match rule to
16172 Vdbus_registered_objects_table. (Bug#9581)
16173 (Fdbus_register_method, Vdbus_registered_objects_table):
16176 2011-09-24 Jim Meyering <meyering@redhat.com>
16178 do not ignore write error for any output size
16179 The previous change was incomplete.
16180 While it makes emacs --batch detect the vast majority of stdout
16181 write failures, errors were still ignored whenever the output size is
16182 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16183 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16184 && echo FAIL: ignored write error
16185 FAIL: ignored write error
16186 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16187 && echo FAIL: ignored write error
16188 FAIL: ignored write error
16189 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16191 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16193 * emacs.c (Fkill_emacs): In noninteractive mode exit
16194 non-successfully if a write error occurred on stdout. (Bug#9574)
16196 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16198 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16201 * dispextern.h (struct it): Update the comment documenting what
16204 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16206 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16207 a display string, extend search for cursor position to end of row.
16208 (find_row_edges): If the row ends in a newline from a display
16209 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16210 Handle the case of a display string with multiple newlines.
16211 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16212 non-empty line. Fixes confusing cursor motion with arrow keys at
16213 the beginning of a line that starts with whitespace.
16215 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16217 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16220 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16222 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16223 boolean (Bug#9154).
16225 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16227 * xdisp.c (display_line): Record maximum and minimum buffer
16228 positions even if no glyphs were produced (e.g., by a zero-width
16229 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16230 buffer positions that will be removed from the glyph row because
16232 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16233 column is beyond frame width: don't subtract 1 "pixel" when
16234 computing width of the stretch.
16235 (reseat_at_next_visible_line_start): Undo the change made on
16236 2011-09-17 that saved paragraph information and restored it after
16237 the call to `reseat'. (Bug#9545)
16239 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16241 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16242 and turn window cursor on if cleared (Bug#9415).
16244 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16246 * search.c (boyer_moore): Take unibyte characters from pattern
16247 literally. (Bug#9458)
16249 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16251 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16253 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16255 Fix minor problem found by static checking.
16256 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16257 initialized, to pacify gcc -Wuninitialized.
16259 * fileio.c: Report proper errno when syscall falls.
16260 (Finsert_file_contents): Save and restore errno,
16261 so that report_file_error outputs the correct diagnostic.
16262 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16264 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16266 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16268 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16270 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16271 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16273 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16275 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16276 about the current paragraph and restore it after the call to reseat.
16278 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16279 (bidi_find_paragraph_start): Search back for paragraph beginning
16280 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16281 (bidi_move_to_visually_next): Only trigger paragraph-related
16282 computations when the last character is a newline or at EOB, not
16283 just any NEUTRAL_B. (Bug#9470)
16285 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16286 truncated lines if point is covered by a display string. (Bug#9524)
16288 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16290 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16291 (cons_to_x_long): New function.
16292 (lisp_data_to_selection_data): Use it. Correct the test for
16293 short-versus-long data; it was negated. Break out of vector
16294 loop, for efficiency, when a long datum is discovered.
16296 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16298 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16300 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16302 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16303 GCC PR/17406) by declaring this function with external scope.
16305 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16307 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16308 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16310 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16312 * editfns.c (Fformat): Correctly handle text properties on "%%".
16314 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16316 * xterm.c (x_draw_composite_glyph_string_foreground):
16317 * w32term.c (x_draw_composite_glyph_string_foreground):
16318 * term.c (encode_terminal_code):
16319 * composite.c (composition_update_it, get_composition_id):
16320 * xdisp.c (get_next_display_element)
16321 (fill_composite_glyph_string): Add comments about special meaning
16322 of TAB characters in a composition.
16324 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16326 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16327 This occurs when processing a multibyte format.
16328 Problem reported by Wolfgang Jenker.
16330 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16332 * xdisp.c (try_cursor_movement): Only check for exact match if
16333 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16335 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16337 Remove unused external symbols.
16338 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16339 * xdisp.c (calc_pixel_width_or_height): Now static.
16340 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16341 * indent.c (check_display_width):
16342 * w32term.c: Fix comment to match code.
16343 * xterm.c, xterm.h (x_catching_errors): Remove.
16345 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16347 * xselect.c: Use signed conversions more consistently (Bug#9498).
16348 (selection_data_to_lisp_data): Assume incoming selection data are
16349 signed integers, not unsigned. This is to be consistent with
16350 outgoing selection data, which was modified to use signed integers
16351 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16352 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16353 expects long, not unsigned long.
16355 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16357 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16358 computation of loop end. Reported by Johan Bockgård
16361 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16363 * frame.c (Fother_visible_frames_p): Function deleted.
16365 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16367 * indent.c (compute_motion): Process display vector front to back
16368 rather than the other way around. (Bug#2496)
16370 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16372 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16374 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16376 * minibuf.c (Fread_from_minibuffer): Doc fix.
16378 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16380 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16381 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16383 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16385 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16386 value for non-existent files.
16388 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16390 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16391 set its "size" to -1. This will set the modtime_size field of
16392 the corresponding buffer to -1, which is what
16393 verify-visited-file-modtime expects for files that do not exist.
16396 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16398 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16400 * lisp.h: ... from here. push_key_description is no longer
16401 defined in keyboard.c, so its declaration should not be in
16402 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16403 logically belongs with push_key_description.
16405 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16407 * buffer.h: Include <sys/types.h> instead of <time.h>.
16408 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16409 Problem reported by Herbert J. Skuhra.
16411 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16413 * xml.c (parse_region): Make the parsing work for
16414 non-comment-starting XML files again (bug#9144).
16416 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16418 * image.c (gif_load): Fix calculation of bottom and right corner.
16421 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16423 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16424 redisplay in small windows.
16426 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16428 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16430 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16432 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16433 Operate on live windows only.
16435 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16437 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16439 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16441 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16442 only under bidi iteration.
16444 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16446 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16448 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16450 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16451 Without this fix, the command to link temacs failed due to an
16452 undefined symbol __builtin_isnan. This is because
16453 /usr/include/iso/math_c99.h #defines isnan(x) to
16454 __builtin_isnan(x), but the bundled gcc, which identifies itself
16455 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16457 * floatfns.c (isnan): #undef, and then #define to a clone of
16459 (Fisnan): Always define, since it's always available now.
16460 (syms_of_floatfns): Always define isnan at the Lisp level.
16462 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16464 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16466 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16468 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16469 The previous code assumed that file offsets (off_t values) fit in
16470 EMACS_INT variables, which is not true on typical 32-bit hosts.
16471 The code messed up by falsely reporting buffer overflow in cases
16472 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16473 when "big" contains more than 2**29 bytes, even though this
16474 inserts just one byte and does not overflow the buffer.
16475 (Finsert_file_contents): Store file offsets as off_t
16476 values, not as EMACS_INT values. Check for overflow when
16477 converting between EMACS_INT and off_t. When checking for
16478 buffer overflow or for overlap, take the offsets into account.
16479 Don't use EMACS_INT for small values where int suffices.
16480 When checking for overlap, fix a typo: ZV was used where
16481 ZV_BYTE was intended.
16482 (Fwrite_region): Don't assume off_t fits into 'long'.
16483 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16485 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16487 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16489 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16491 sprintf-related integer and memory overflow issues (Bug#9412).
16493 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16494 (esprintf, exprintf, evxprintf): New functions.
16495 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16496 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16497 (modify_event_symbol): Do not assume that the length of
16498 name_alist_or_stem is safe to alloca and fits in int.
16499 (Fexecute_extended_command): Likewise for function name and binding.
16500 (Frecursion_depth): Wrap around reliably on integer overflow.
16501 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16502 since some callers pass EMACS_INT values.
16503 (Fsingle_key_description): Don't crash if symbol name contains more
16504 than MAX_ALLOCA bytes.
16505 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16506 (get_minibuffer): Arg is now EMACS_INT, not int.
16507 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16508 (esprintf, exprintf, evxprintf): New decls.
16509 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16511 * dbusbind.c (signature_cat): New function.
16512 (xd_signature, Fdbus_register_signal):
16513 Do not overrun buffer; instead, report string overflow.
16515 * dispnew.c (add_window_display_history): Don't overrun buffer.
16516 Truncate instead; this is OK since it's just a log.
16518 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16519 even if the time zone offset is outlandishly large.
16520 Don't mishandle offset == INT_MIN.
16522 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16523 when creating daemon; the previous buffer-overflow check was incorrect.
16525 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16526 which has the guts of the old verror function.
16528 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16529 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16531 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16532 (font_unparse_xlfd): Don't blindly alloca long strings.
16533 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16534 fits in int, when using sprintf. Use single snprintf to count
16535 length of string rather than counting it via multiple sprintfs;
16536 that's simpler and more reliable.
16537 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16538 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16539 sprintf, in case result does not fit in int.
16541 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16542 (fontset_from_font): Print it.
16544 * frame.c (tty_frame_count): Now printmax_t, not int.
16545 (make_terminal_frame, set_term_frame_name): Print it.
16546 (x_report_frame_params): In X, window IDs are unsigned long,
16547 not signed long, so print them as unsigned.
16548 (validate_x_resource_name): Check for implausibly long names,
16549 and don't assume name length fits in 'int'.
16550 (x_get_resource_string): Don't blindly alloca invocation name;
16551 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16554 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16555 (xg_check_special_colors, xg_set_geometry):
16556 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16558 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16559 Use esprintf, not sprintf, in case result does not fit in int.
16561 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16562 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16563 it as a large positive number.
16564 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16565 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16567 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16568 in case result does not fit in int.
16570 * print.c (float_to_string): Detect width overflow more reliably.
16571 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16572 buffer overrun. Don't assume list length fits in 'int'. Treat
16573 print length of 0 as 0, not as infinity; to be consistent with other
16574 uses of print length in this function. Don't overflow print length
16575 index. Don't assume hash table size fits in 'long', or that
16576 vectorlike size fits in 'unsigned long'.
16578 * process.c (make_process): Use printmax_t, not int, to format
16579 process-name gensyms.
16581 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16583 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16584 to avoid potential buffer overrun.
16586 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16587 if X resource line is longer than 512 bytes.
16589 * xfns.c (x_window): Make sprintf buffer a bit bigger
16590 to avoid potential buffer overrun.
16592 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16594 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16596 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16598 Integer overflow fixes for scrolling, etc.
16599 Without these, Emacs silently mishandles large integers sometimes.
16600 For example, "C-u 4294967297 M-x recenter" was treated as if
16601 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16603 * xdisp.c (try_window_id): Check Emacs fixnum range before
16604 converting to 'int'.
16606 * window.c (window_scroll_line_based, Frecenter):
16607 Check that an Emacs fixnum is in range before assigning it to 'int'.
16608 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16609 values converted from Emacs fixnums.
16610 (Frecenter): Don't wrap around a line count if it is out of 'int'
16611 range; instead, treat it as an extreme value.
16612 (Fset_window_configuration, compare_window_configurations):
16613 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16615 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16616 that can exceed INT_MAX. Check that EMACS_INT value is in range
16617 before assigning it to the (possibly-narrower) index.
16618 (match_limit): Don't assume that a fixnum can fit in 'int'.
16620 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16623 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16624 (Fvertical_motion): Don't wrap around LINES values that don't fit
16625 in 'int'. Instead, treat them as extreme values. This is good
16626 enough for windows, which can't have more than INT_MAX lines anyway.
16628 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16630 * Require libxml/parser.h to avoid compilation warning.
16632 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16634 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16635 since this reportedly can destroy thread storage.
16637 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16639 * syntax.c (find_defun_start): Update all cache variables if
16640 exiting early (Bug#9401).
16642 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16644 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16646 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16647 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16648 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16650 * term.c (tty_append_glyph): New function.
16651 (produce_stretch_glyph): Static function and its prototype deleted.
16653 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16656 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16658 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16659 when checking :margin (Bug#9390).
16660 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16661 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16662 so that the name doesn't mislead. All uses changed.
16664 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16666 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16669 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16671 * xdisp.c (move_it_to): Don't bail out early when reaching
16672 position beyond to_charpos, if we are scanning backwards.
16673 (move_it_vertically_backward): When DY == 0, make sure we get to
16674 the first character in the line after the newline.
16676 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16678 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16679 (ccl_driver): Do not generate an out-of-range pointer.
16680 (Fccl_execute_on_string): Remove unnecessary check for
16681 integer overflow, noted by Stefan Monnier in
16682 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16683 Remove a FIXME that didn't need fixing.
16684 Simplify the newly-introduced buffer reallocation code.
16686 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16688 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16690 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16692 Integer and memory overflow issues (Bug#9196).
16694 * doc.c (get_doc_string): Rework so that
16695 get_doc_string_buffer_size is the actual buffer size, rather than
16696 being 1 less than the actual buffer size; this makes xpalloc more
16699 * image.c (x_allocate_bitmap_record, cache_image):
16700 * xselect.c (Fx_register_dnd_atom):
16701 Simplify previous changes by using xpalloc.
16703 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16704 since either will do and ptrdiff_t is convenient with xpalloc.
16706 * charset.c (charset_table_size)
16707 (struct charset_sort_data.priority): Now ptrdiff_t.
16708 (charset_compare): Don't overflow if priorities differ greatly.
16709 (Fsort_charsets): Don't assume list length fits in int.
16710 Check for size-calculation overflow when allocating sort data.
16711 (syms_of_charset): Allocate an initial charset table that is
16712 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16714 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16716 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16717 The actual value is always <= INT_MAX, and leaving it unsigned made
16718 overflow checking harder.
16720 * dispextern.h (struct glyph_matrix.rows_allocated)
16721 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16722 with xpalloc. The values are still always <= INT_MAX.
16724 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16726 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16727 (SAFE_NALLOCA): New macro.
16729 * region-cache.c (struct boundary.pos, find_cache_boundary)
16730 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16731 (set_cache_region, invalidate_region_cache)
16732 (revalidate_region_cache, know_region_cache, region_cache_forward)
16733 (region_cache_backward, pp_cache):
16734 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16735 so that ptrdiff_t * can be passed to xpalloc.
16736 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16737 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16738 (pp_cache): Don't assume cache_len fits in int.
16739 * region-cache.h: Adjust extern decls to match.
16741 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16742 EMACS_INT, since either will do, for xpalloc.
16744 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16745 (xnmalloc, xnrealloc, xpalloc): New functions.
16747 * bidi.c (bidi_shelve_header_size): New constant.
16748 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16749 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16751 * bidi.c (bidi_cache_shrink):
16752 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16754 Don't update size of array until after memory allocation succeeds,
16755 because xmalloc/xrealloc may not return.
16756 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16757 now that we have proper integer overflow checking.
16758 (record_overlay_string, overlay_strings): Catch overflows when
16759 calculating size of overlay_str_buf.
16761 * callproc.c (Fcall_process): Check for size overflow when
16762 calculating size of args2.
16763 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16764 Normally we prefer signed values, but sticking with ptrdiff_t would
16765 require adding more-complicated checks.
16767 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16768 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16769 Redo buffer-overflow calculations to avoid integer overflow.
16770 Add a FIXME comment where memory seems to be over-allocated.
16772 * character.c (Fstring): Check for size-calculation overflow.
16774 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16775 unnecessary integer overflow. Check for size overflow.
16776 (encode_coding_object): Don't update size until xmalloc succeeds.
16778 * composite.c (get_composition_id): Check for overflow in glyph
16779 length calculations.
16781 Integer and memory overflow fixes for display code.
16782 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16783 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16784 (scrolling_window): Check for overflow in size calculations.
16785 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16786 Don't assume glyph table len fits in int.

16788 (row_table_size): Now ptrdiff_t, not int.
16789 (scrolling_window): Avoid overflow in size calculations.
16790 Don't update size until allocation succeeds.
16791 * fns.c (concat): Check for overflow in size calculations.
16792 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16793 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16794 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16796 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16797 (get_doc_string): Check for size calculation overflow.
16798 Don't update size until allocation succeeds.
16799 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16800 EMACS_INT, where ptrdiff_t will do.
16801 (Fsubstitute_command_keys): Check for string overflow.
16803 * editfns.c (set_time_zone_rule): Don't assume environment length
16805 (message_length): Now ptrdiff_t, not int.
16806 (Fmessage_box): Don't update size until allocation succeeds.
16807 Don't assume message length fits in int.
16808 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16810 * emacs.c (main): Do not reallocate argv, since there is a null at
16811 the end that can be overwritten, and this way there's no need to
16812 worry about size-calculation overflow.
16813 (sort_args): Check for size-calculation overflow.
16815 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16817 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16819 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16820 (x_set_scroll_bar_width, x_figure_window_size):
16821 Check for integer overflow.
16822 (x_set_alpha): Do not assume XINT fits in int.
16824 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16825 This is for the members text_lines, text_cols, total_lines, total_cols,
16826 where the system imposes an 'int' limit.
16828 * fringe.c (Fdefine_fringe_bitmap):
16829 Don't update size until alloc works.
16831 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16832 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16834 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16835 Check for size-calculation overflow.
16836 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16837 do, as we prefer signed integers.
16838 (id_to_widget.max_size, id_to_widget.used)
16839 (xg_store_widget_in_map, xg_remove_widget_from_map)
16840 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16841 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16842 Use and return ptrdiff_t, not int.
16843 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16844 * gtkutil.h: Change prototypes to match the above.
16846 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16847 are duplicate now that they've been promoted to lisp.h.
16848 (x_allocate_bitmap_record, x_alloc_image_color)
16849 (make_image_cache, cache_image, xpm_load):
16850 Don't update size until alloc is done.
16851 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16853 Check for size calculation overflow.
16854 (ct_colors_allocated_max): New constant.
16855 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16858 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16859 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16860 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16861 Use ptrdiff_t, not int, to count maps.
16862 (read_char_minibuf_menu_prompt): Check for overflow in size
16863 calculations. Don't update size until allocation succeeds.
16864 Redo calculations to avoid overflow.
16865 * keyboard.h: Change prototypes to match the above.
16867 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16869 (current_minor_maps): Check for size calculation overflow.
16870 * keymap.h: Change prototypes to match the above.
16872 * lread.c (read1, init_obarray): Don't update size until alloc done.
16874 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
16875 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
16877 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
16878 Now ptrdiff_t, not int.
16879 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
16880 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
16882 * process.c (Fnetwork_interface_list): Check for overflow
16883 in size calculation.
16885 * region-cache.c (move_cache_gap): Check for size calculation overflow.
16887 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
16888 overflow. Don't bother calling xmalloc when xrealloc will do.

16891 (Fset_match_data): Don't assume list lengths fit in 'int'.
16893 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16894 for command line length. Do not attempt to address one before the
16895 beginning of an array, as that's not portable.
16897 * term.c (max_frame_lines): Remove; unused.
16898 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16900 (encode_terminal_code, calculate_costs): Check for size
16901 calculation overflow.

16903 table lengths and related sizes. Don't update size until alloc
16904 done. Redo calculations to avoid overflow.
16905 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16907 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16908 subtracting pointers.
16909 (gobble_line): Check for overflow more carefully. Don't update size
16912 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
16913 Don't update size until alloc done.
16914 Redo size calculations to avoid overflow.
16915 Check for size calculation overflow.
16916 (main) [DEBUG]: Fix typo in invoking tparam1.

16923 Use ptrdiff_t, not int, for sizes.
16924 (Finternal_make_lisp_face, cache_face):
16925 Check for size calculation overflow.
16926 (cache_face): Treat size calculation overflows as if they were
16927 memory exhaustion (the usual treatment), rather than aborting.
16929 * xfns.c (x_encode_text, x_set_name_internal)
16930 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16931 sizes, since they can exceed INT_MAX in size. Check for size
16932 calculation overflow.
16934 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16935 (xg_select): Check for size calculation overflow.
16936 Don't update size until alloc done.
16938 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16939 as sprintf is limited to int lengths.
16941 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16942 (X_LONG_MIN): New macros.
16943 Use them to make the following changes clearer.
16944 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16945 This change doesn't affect the value now, but it may help remind
16946 future maintainers not to raise the value too much later.
16947 (SELECTION_QUANTUM): Remove, replacing with ...
16948 (selection_quantum): ... new function, which avoids overflow.
16950 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16951 assumption that selection length fits in 'int'.
16952 (x_reply_selection_request, x_handle_selection_request)
16953 (x_get_window_property, receive_incremental_selection)
16954 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16955 (lisp_data_to_selection_data, clean_local_selection_data):
16956 Use ptrdiff_t, not int, to record length of selection.
16957 (x_reply_selection_request, x_get_window_property)
16958 (receive_incremental_selection, x_property_data_to_lisp):
16959 Redo calculations to avoid overflow.
16960 (x_reply_selection_request): When sending hint, ceiling it at
16961 X_LONG_MAX rather than relying on wraparound overflow to send
16963 (x_get_window_property, receive_incremental_selection)
16964 (lisp_data_to_selection_data, x_property_data_to_lisp):
16965 Check for size-calculation overflow.

16968 Don't store size until memory allocation succeeds.
16969 (x_get_window_property): Plug memory leak on memory exhaustion.
16970 Don't double-block input; malloc is safe here. Don't assume 2**34
16971 - 4 fits in unsigned long. Add an xassert to check
16972 XGetWindowProperty overflow. Be more careful about overflow
16973 calculations, and distinguish size from memory overflow better.
16974 (receive_incremental_selection): When tracing, don't assume
16975 unsigned int is less than INT_MAX.
16976 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16977 harmful) conversions of unsigned short to int.
16978 (lisp_data_to_selection_data): Don't assume that integers
16979 in the range -65535 through -1 fit in an X unsigned short.
16980 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16981 result parameters unless successful. Rely on cons_to_unsigned
16982 to report problems with elements; the old code wasn't right anyway.
16983 (x_check_property_data): Check for int overflow; we cannot use
16984 a wider type due to X limits.
16985 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16987 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16989 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16990 (x_term_init): Check for size calculation overflow.
16991 (x_color_cells): Don't store size until memory allocation succeeds.
16992 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16993 Don't assume alloca size is less than MAX_ALLOCA.
16994 (x_term_init): Don't assume length fits in int (sprintf is limited
16997 Use ptrdiff_t for composition IDs.
16998 * character.c (lisp_string_width):

17016 * image.c (xpm_get_color_table_h):
17017 * lisp.h (hash_lookup, hash_put):
17018 * minibuf.c (Ftest_completion):
17019 Use ptrdiff_t for hash table indexes, not int (which is too
17020 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17021 32-bit --with-wide-int hosts).
17023 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17024 Add a FIXME comment about memory leaks.
17025 (syms_of_charset): Don't assume xmalloc returns.

17029 * character.h (CHAR_WIDTH):
17030 * indent.c (MULTIBYTE_BYTES_WIDTH):
17031 Use sanitize_char_width to avoid undefined and/or bad behavior
17032 with outlandish widths.
17033 * character.h (sanitize_tab_width): Rename from sanitize_width,
17034 now that we have two such functions. All uses changed.
17035 (sanitize_char_width): New inline function.
17037 Don't assume that tab-width fits in int.
17038 * character.h (sanitize_width): New inline function.

17046 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
17048 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
17049 Remove unreachable code.
17050 (read_hex, load_charset_map_from_file): Check for integer overflow.
17052 * xterm.c: Don't go over XClientMessageEvent limit.
17053 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17054 (x_send_scroll_bar_event): Likewise. Check that the size does not
17055 exceed limits imposed by XClientMessageEvent, as well as the usual
17056 ptrdiff_t and size_t limits.
17058 * keyboard.c: Overflow, signedness and related fixes.
17059 (make_lispy_movement): Use same integer type in forward decl
17060 that is used in the definition.
17061 (read_key_sequence, keyremap_step):
17062 Change bufsize argument back to int, undoing my 2011-03-30 change.
17063 We prefer signed types, and int is wide enough here.
17064 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17065 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17066 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17067 length, not size_t. Use ptrdiff_t for index, not int.
17068 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17069 possibility of integer overflow.
17071 Overflow, signedness and related fixes for images.
17073 * dispextern.h (struct it.stack[0].u.image.image_id)
17074 (struct_it.image_id, struct image.id, struct image_cache.size)

17081 * xdisp.c (calc_pixel_width_or_height):
17082 * xfns.c (image_cache_refcount):

17092 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17093 (lookup_image): Remove unnecessary tests.
17094 (xbm_image_p): Locals are now of int, not EMACS_INT,
17095 since parse_image_check makes sure they fit into int.
17096 (png_load, gif_load, svg_load_image):
17097 Prefer int to unsigned where either will do.
17098 (tiff_handler): New function, combining the cores of the
17099 old tiff_error_handler and tiff_warning_handler.
17100 This function is rewritten to use vsnprintf and thereby avoid
17101 stack buffer overflows. It uses only the features of vsnprintf
17102 that are common to both POSIX and native Microsoft.
17103 (tiff_error_handler, tiff_warning_handler): Use it.
17104 (tiff_load, gif_load, imagemagick_load_image):
17105 Don't assume :index value fits in 'int'.
17106 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17107 (imagemagick_load_image): Check that crop parameters fit into
17108 the integer types that MagickCropImage accepts. Don't assume
17109 Vimagemagick_render_type has a nonnegative value. Don't assume
17110 size_t fits in 'long'.
17111 (gs_load): Use printmax_t to print the widest integers possible.
17112 Check for integer overflow when computing image height and width.
17114 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17116 * xdisp.c (redisplay_window): Don't force window start if point
17117 will be invisible in the resulting window. (Bug#9324)

17121 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
17122 the display spec is of the form `(space ...)'.
17123 (handle_display_spec): Return the value returned by
17124 handle_single_display_spec, not just 1 or zero.
17125 (handle_single_display_spec): If the display spec is of the form
17126 `(space ...)', and specifies display in the text area, return 2
17128 (try_cursor_movement): Check for the need to scroll more
17129 accurately, and prefer exact match for point under bidi.
17130 Don't advance `row' beyond the last row of the window.
17132 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17133 into disp_prop; all users changed.
17135 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

17147 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17148 buffers, return left-to-right.
17149 (set_cursor_from_row): Consider candidate row a win if its glyph
17150 represents a newline and point is on that newline. Fixes cursor
17151 positioning on the newline at EOL of R2L text within L2R
17152 paragraph, and vice versa.
17153 (try_cursor_movement): Check continued rows, in addition to
17154 continuation rows. Fixes unwarranted scroll when point enters a
17155 continued line of R2L text within an L2R paragraph, or vice versa.
17156 (cursor_row_p): Consider the case of point being equal to
17157 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17158 from the end of a short line to the beginning of a continued line
17159 of R2L text within L2R paragraph.
17160 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17161 composed characters.

17186 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17187 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17188 candidate is selected by the mouse, and that candidate has a
17189 composed character under the mouse.
17191 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17192 coordinates reported by pos-visible-in-window-p for a composed
17193 character in column zero.
17195 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17197 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17199 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17201 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17202 consider it a hit if to_charpos is anywhere in the range of the
17203 composed buffer positions.
17205 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17207 * image.c (gif_load): Don't assume that each subimage has the same
17208 dimensions as the base image. Handle disposal method that is
17209 "undefined" by the gif spec (Bug#9335).
17211 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17213 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17218 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17219 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17220 from an Org mode buffer to a Speedbar frame.
17222 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17223 a composition, take its buffer position from IT->cmp_it.charpos.
17224 Fixes cursor positioning at the beginning of a line that begins
17225 with a composed character.
17227 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17229 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17230 character bidirectional type, use STRONG_L instead. Fixes crashes
17231 in a buffer produced by `describe-categories'.
17233 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17234 members before the level stack, so they would be saved and
17235 restored when copying iterator state. Fixes incorrect reordering
17236 around TABs covered by display properties.
17238 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

17264 Fix memory allocation problems in Cygwin build (Bug#9273).
17266 * unexcw.c ( __malloc_initialized): Declare external variable.
17267 (fixup_executable): Force the dumped emacs to reinitialize malloc.
17269 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
17271 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

17310 * xdisp.c (move_it_in_display_line_to): Don't invoke
17311 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17312 ppos_it. Fixes vertical cursor motion when line beginning is
17313 covered by an image. (Bug#9296)
17315 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17317 * nsterm.h (ns_run_ascript): Declare.

17324 the event loop. Get status from as_status (Bug#7276).
17326 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17327 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17328 the event loop (Bug#7276).

17341 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17344 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17346 * xfaces.c (Qframe_set_background_mode): Now static.
17347 * dispextern.h (Qframe_set_background_mode): Remove decl.
17349 * process.c (Fnetwork_interface_info): Declare local only if needed.
17351 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17353 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17354 (Fnetwork_interface_list): Allocate in increments of bytes instead
17355 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17356 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17358 (struct ifflag_def): notrailers is smart on OSX.
17359 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17360 Get hardware address with getifaddrs if available.
17362 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17364 * xdisp.c (iterate_out_of_display_property): xassert that
17365 IT->position is set to within IT->object's boundaries. Break from
17366 the loop as soon as EOB is reached; avoids infloops in redisplay
17367 when IT->position is set up wrongly due to some bug.
17368 Set IT->current to match the bidi iterator unconditionally.
17369 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17370 entry. Force push_it to save on the stack the current
17371 buffer/string position, to be restored by pop_it. Fix flags in
17372 the iterator structure wrt the object coming from a display
17373 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17374 properties. (Bug#9284)
17376 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17378 * fontset.c (fontset_get_font_group): Add proper type checks.
17381 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17383 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17384 and LC_VERSION_MIN_MACOSX.
17385 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17386 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17388 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17390 * xdisp.c (forward_to_next_line_start): Allow to use the
17391 no-display-properties-and-no-overlays under bidi display.
17392 Set disp_pos in the bidi iterator to avoid searches for display
17393 properties and overlays.
17395 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17397 * editfns.c (Fset_time_zone_rule): Document relationship with the
17400 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17401 the font entity extracted from the cache (Bug#8109).
17403 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17405 * composite.c (autocmp_chars): Don't reset point. That is done by
17406 restore_point_unwind (Bug#5984).
17408 2011-08-07 Juri Linkov <juri@jurta.org>
17410 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17411 to show the arg `TIME' instead of `TIMEVAL'.
17413 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17415 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17416 display property strides EOL and includes a newline, as in
17417 longlines-mode. (Bug#9254)
17418 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17419 word-wrap under bidirectional display. (Bug#9224)
17421 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17422 is non-zero, even if the data buffer is NULL. Fixes a crash in
17423 vertical-motion with longlines-mode. (Bug#9254)
17425 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17427 * bidi.c <bidi_cache_total_alloc>: Now static.
17428 (bidi_initialize): Initialize bidi_cache_total_alloc.
17430 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17433 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17434 amount allocated this far in `bidi_cache_total_alloc'.
17435 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17436 non-zero, only free the data buffer without restoring the cache
17437 contents. All callers changed.
17439 * dispextern.h (bidi_unshelve_cache): Update prototype.
17441 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17442 (move_it_in_display_line, move_it_to)
17443 (move_it_vertically_backward, move_it_by_lines): Replace the call
17444 to xfree to an equivalent call to bidi_unshelve_cache.
17445 (move_it_in_display_line_to): Fix logic of returning
17446 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17448 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17450 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17451 came from a string character with a `cursor' property. (Bug#9229)
17453 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17455 * Makefile.in (LIB_PTHREAD): New variable.
17456 (LIBES): Add LIB_PTHREAD (Bug#9216).
17458 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17459 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17461 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17463 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17465 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17467 * xterm.c (x_find_topmost_parent): New function.
17468 (x_set_frame_alpha): Find topmost parent window with
17469 x_find_topmost_parent and set the property there also (bug#9181).
17470 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17472 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17474 * callproc.c (Fcall_process): Avoid vfork clobbering
17475 the local vars buffer, coding_systems, current_dir.
17477 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17479 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17481 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17483 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17484 so that it is not optimized away.
17486 * xdisp.c (compute_display_string_pos): Remove unused local.
17488 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17490 Fix slow cursor motion and scrolling in large buffers with
17491 selective display, like Org Mode buffers. (Bug#9218)
17493 * dispextern.h (struct bidi_it): New member disp_prop_p.
17495 * xdisp.c: Remove one-slot cache of display string positions.
17496 (compute_display_string_pos): Accept an additional argument
17497 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17498 for a display string or property. If found, set DISP_PROP_P
17501 * bidi.c (bidi_fetch_char): Accept an additional argument
17502 DISP_PROP_P, and pass it to compute_display_string_pos.
17503 Only handle text covered by a display string if DISP_PROP_P is returned
17504 non-zero. All callers of bidi_fetch_char changed.
17506 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17508 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17510 2010-12-03 Don March <don@ohspite.net>
17512 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17513 last character M-[char] is translated to ESC [char] (bug#7541).
17515 2011-08-02 Kenichi Handa <handa@m17n.org>
17517 * lisp.h (uniprop_table): Extern it.
17519 * chartab.c (uniprop_table): Make it non-static.
17521 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17523 * xdisp.c (forward_to_next_line_start): Accept additional argument
17524 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17526 (reseat_at_next_visible_line_start): Use the bidi iterator state
17527 returned by forward_to_next_line_start to restore the state of
17528 it->bidi_it after backing up to previous newline. (Bug#9212)
17530 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17532 * regex.c (re_comp): Protoize.
17533 (re_exec): Fix return type.
17534 (regexec): Fix type of `ret'. (Bug#9203)
17536 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17538 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17539 This is needed if max-image-size is a floating-point number.
17541 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17543 * print.c (print_object): Print empty symbol as ##.
17545 * lread.c (read1): Read ## as empty symbol.
17547 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17549 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17550 setting frame foreground color (Bug#9175).
17551 (x_set_background_color): Likewise.
17553 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17554 contents (Bug#9176).
17555 (EmacsTooltip -init): Remove bezels and add shadows to
17558 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17559 or scroll bar (Bug#8470).
17561 * nsfont.m (nsfont_open): Remove assignment to voffset and
17562 unnecessary vars hshink, expand, hd, full_height, min_height.
17563 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17565 * nsterm.h (nsfont_info): Remove voffset field.
17567 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17569 Implement strike-through and overline on NextStep (Bug#8863).
17571 * nsfont.m (nsfont_open): Use underline position provided by font,
17572 instead of hard-coded value of 2.
17573 (nsfont_draw): Call ns_draw_text_decoration instead.
17575 * nsterm.h: Add declaration for ns_draw_text_decoration.
17577 * nsterm.m (ns_draw_text_decoration): New function for drawing
17578 underline, overline, and strike-through.
17579 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17580 ns_draw_text_decoration. Change treatment of cursor drawing to
17581 accommodate underlining, etc.
17583 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17585 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17588 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17590 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17591 Without this fix, if a signal arrives just after memory fills up,
17592 'malloc' might be invoked reentrantly.
17594 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17595 In other words, assume that every image size is allowed, on non-X
17596 hosts. This assumption is probably wrong, but it lets Emacs compile.
17598 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17600 * regex.c (re_iswctype): Convert return values to boolean.
17602 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17604 * xdisp.c (compute_display_string_pos): Don't use cached display
17605 string position if the buffer had its restriction changed.
17608 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17610 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17612 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17614 Integer signedness and overflow and related fixes. (Bug#9079)
17616 * bidi.c: Integer size and overflow fixes.
17617 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17618 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17619 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17620 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17621 (bidi_find_other_level_edge):
17622 Use ptrdiff_t instead of EMACS_INT where either will do.
17623 This works better on 32-bit hosts configured --with-wide-int.
17624 (bidi_cache_ensure_space): Check for size-calculation overflow.
17625 Use % rather than repeated addition, for better worst-case speed.
17626 Don't set bidi_cache_size until after xrealloc returns, because it
17628 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17629 (bidi_cache_ensure_space): Also check that the bidi cache size
17630 does not exceed that of the largest Lisp string or buffer. See Eli
17631 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17633 * alloc.c (__malloc_size_t): Remove.
17634 All uses replaced by size_t. See Andreas Schwab's note
17635 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17637 * image.c: Improve checking for integer overflow.
17638 (check_image_size): Assume that f is nonnull, since
17639 it is always nonnull in practice. This is one less thing to
17640 worry about when checking for integer overflow later.
17641 (x_check_image_size): New function, which checks for integer
17642 overflow issues inside X.
17643 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17644 This removes the need for a memory_full check.
17645 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17646 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17647 (xbm_read_bitmap_data): Change locals back to 'int', since
17648 their values must fit in 'int'.
17649 (xpm_load_image, png_load, tiff_load):
17650 Invoke x_create_x_image_and_pixmap earlier,
17651 to avoid much needless work if the image is too large.
17652 (tiff_load): Treat overly large images as if
17653 x_create_x_image_and_pixmap failed, not as malloc failures.
17654 (gs_load): Use x_check_image_size.
17656 * gtkutil.c: Omit integer casts.
17657 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17658 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17660 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17662 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17663 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17664 would wrongly return t on a 64-bit host.
17666 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17667 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17668 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17669 and therefore cause GCC to emit a bogus diagnostic in some cases.
17671 * image.c: Integer signedness and overflow and related fixes.
17672 This is not an exhaustive set of fixes, but it's time to
17673 record what I've got.
17674 (lookup_pixel_color, check_image_size): Remove redundant decls.
17675 (check_image_size): Don't assume that arbitrary EMACS_INT values
17676 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17677 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17678 (tiff_load, imagemagick_load_image):
17679 Check for overflow in size calculations.
17680 (x_create_x_image_and_pixmap): Remove unnecessary test for
17681 xmalloc returning NULL; that can't happen.
17682 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17683 (xpm_color_bucket): Use better integer hashing function.
17684 (xpm_cache_color): Don't possibly over-allocate memory.
17685 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17686 (gif_memory_source):
17687 Use ptrdiff_t, not int or size_t, to record sizes.
17688 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17689 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17690 either works, as we prefer signed integers.
17691 (tiff_read_from_memory, tiff_write_from_memory):
17692 Return tsize_t, not size_t, since that's what the TIFF API wants.
17693 (tiff_read_from_memory): Don't fail simply because the read would
17694 go past EOF; instead, return a short read.
17695 (tiff_load): Omit no-longer-needed casts.
17696 (Fimagemagick_types): Don't assume size fits into 'int'.
17698 Improve hashing quality when configured --with-wide-int.
17699 * fns.c (hash_string): New function, taken from sxhash_string.
17700 Do not discard information about ASCII character case; this
17701 discarding is no longer needed.
17702 (sxhash-string): Use it. Change sig to match it. Caller changed.
17703 * lisp.h: Declare it.
17704 * lread.c (hash_string): Remove, since we now use fns.c's version.
17705 The fns.c version returns a wider integer if --with-wide-int is
17706 specified, so this should help the quality of the hashing a bit.
17708 * emacs.c: Integer overflow minor fix.
17709 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17710 Define only if GNU_LINUX.
17711 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17713 * dispnew.c: Integer signedness and overflow fixes.
17714 Remove unnecessary forward decls, that were a maintenance hassle.
17715 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17717 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17718 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17719 (prepare_desired_row, line_draw_cost):
17720 Use int, not unsigned, where either works.
17721 (save_current_matrix, restore_current_matrix):
17722 Use ptrdiff_t, not size_t, where either works.
17723 (init_display): Check for overflow more accurately, and without
17724 relying on undefined behavior.
17726 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17727 Remove, replacing with the new symbols in lisp.h. All uses changed.
17728 * fileio.c (make_temp_name):
17729 * filelock.c (lock_file_1, lock_file):
17730 * xdisp.c (message_dolog):
17731 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17732 Use pMd etc. instead.
17733 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17734 replacing the pWIDE etc. symbols removed from editfns.c.
17736 * keyboard.h (num_input_events): Now uintmax_t.
17737 This is (very slightly) less likely to mess up due to wraparound.
17740 * buffer.c: Integer signedness fixes.
17741 (alloc_buffer_text, enlarge_buffer_text):
17742 Use ptrdiff_t rather than size_t when either will do, as we prefer
17745 * alloc.c: Integer signedness and overflow fixes.
17746 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17747 (__malloc_size_t): Default to size_t, not to int.
17748 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17749 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17750 Prefer ptrdiff_t to size_t when either would do, as we prefer
17752 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17753 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17754 Now const. Initialize with values that are in range even if char
17756 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17757 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17758 These functions do the right thing with sizes > 2**32.
17759 (check_depth): Now ptrdiff_t, not int.
17760 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17761 Adjust to new way of storing sizes. Check for size overflow bugs
17763 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17764 slightly wrong anyway, as it missed one instance of
17765 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17766 (refill_memory_reserve): Omit needless cast to size_t.
17767 (mark_object_loop_halt): Mark as externally visible.
17769 * xselect.c: Integer signedness and overflow fixes.
17770 (Fx_register_dnd_atom, x_handle_dnd_message):
17771 Use ptrdiff_t, not size_t, since we prefer signed.
17772 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17773 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17774 x_dnd_atoms_size and x_dnd_atoms_length.
17776 * doprnt.c: Prefer signed to unsigned when either works.
17778 * doprnt.c (doprnt):
17780 * xdisp.c (vmessage):
17781 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17782 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17783 prefer signed arithmetic to avoid comparison confusion.
17784 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17785 but is a bit tricky.
17787 Assume freestanding C89 headers, string.h, stdlib.h.
17788 * data.c, doprnt.c, floatfns.c, print.c:
17789 Include float.h unconditionally.
17790 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17791 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17792 * regex.c: Likewise for stddef.h, string.h.
17793 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17794 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17795 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17796 (STDC_HEADERS): Remove obsolete defines.
17797 * sysdep.c: Include limits.h unconditionally.
17799 Assume support for memcmp, memcpy, memmove, memset.
17800 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17801 * regex.c (memcmp, memcpy):
17802 Remove; we assume C89 now.
17804 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17805 (__malloc_safe_bcopy): Remove; no longer needed.
17807 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17808 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17809 well either way, and we prefer signed to unsigned.
17811 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17813 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17814 closes the connection while we're reading (bug#9182).
17816 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17818 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17819 are specified (Bug#9168).
17821 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17823 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17824 Found by GCC static checking and --with-wide-int on a 32-bit host.
17826 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17828 * xdisp.c (compute_display_string_pos): Fix logic of caching
17829 previous display string position. Initialize cached_prev_pos to
17830 -1. Fixes slow-down at the beginning of a buffer.
17832 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17834 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17835 for attrs[LFACE_FONTSET_INDEX].
17837 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17839 * xml.c (parse_region): Remove unused local
17840 that was recently introduced.
17842 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17844 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17845 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17847 * xdisp.c (move_it_in_display_line_to): Record the best matching
17848 position for TO_CHARPOS while scanning the line, and restore it on
17849 exit if none of the characters scanned was an exact match.
17850 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17851 when exact match is impossible due to invisible text, and the
17852 lines are truncated.
17854 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17856 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17859 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17861 Fix a significant slow-down of cursor motion with C-n, C-p,
17862 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17863 auto-repeat under bidi redisplay in fontified buffers.
17864 * xdisp.c (compute_stop_pos_backwards): New function.
17865 (next_element_from_buffer): Call compute_stop_pos_backwards to
17866 find a suitable prev_stop when we find ourselves before
17868 (reseat): Don't look for prev_stop, as that could mean a very long
17870 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17871 <cached_disp_overlay_modiff>: Cache for last found display string
17873 (compute_display_string_pos): Return the cached position if asked
17874 about the same buffer in the same area of character positions, and
17875 the buffer wasn't changed since the time the display string
17876 position was cached.
17878 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17880 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17881 is an integer, which is important for empty lines. (Bug#9149)
17883 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17885 * frame.c (Fmodify_frame_parameters): In tty case, update the
17886 default face if necessary (Bug#4238).
17888 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17890 * editfns.c (Fstring_to_char): No need to explain what a character
17891 is in the docstring (Bug#6576).
17893 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17895 * xml.c (parse_region): Make sure we always return a tree.
17897 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17899 * xml.c (parse_region): If a document contains only comments,
17902 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17904 * xml.c (make_dom): Return comments, too.
17906 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17909 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17910 and the surrounding thread.
17911 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17912 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17913 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17915 * s/openbsd.h (BROKEN_SIGIO): Define.
17916 * unexelf.c (unexec) [__OpenBSD__]:
17917 Don't update the .mdebug section of the Alpha COFF symbol table.
17919 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17921 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17924 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17926 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17927 This fixes some race conditions on the permissions of any newly
17930 * alloc.c (valid_pointer_p): Use pipe, not open.
17931 This fixes some permissions issues when debugging.
17933 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17934 If fchown fails to set both uid and gid, try to set just gid,
17935 as that is sometimes allowed. Adjust the file's mode to eliminate
17936 setuid or setgid bits that are inappropriate if fchown fails.
17938 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17940 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17941 to compare Lisp_Objects.

17943 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17944 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17946 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17948 * lread.c (read_integer): Unread even EOF character.
17949 (read1): Likewise. Properly record start position of symbol.
17951 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17952 symbol character follows.
17954 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17956 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17957 This works around a problem with the previous change to Fcopy_file.
17958 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17959 and without this change, GCC might complain about discarding
17960 fchown's return value.
17962 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17964 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17966 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17968 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17970 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17972 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17973 it's used from the C level.
17975 * process.c: Use the same condition for POLL_FOR_INPUT in both
17976 keyboard.c and process.c (bug#1858).
17978 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17980 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17981 (Fgnutls_boot): Use it.
17983 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17985 * doc.c (Fsubstitute_command_keys): Revert last change.
17987 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17989 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17990 quotes the next character, and doesn't affect other longer
17991 sequences (bug#8935).
17993 * lread.c (syms_of_lread): Clarify that is isn't only
17994 `eval-buffer' and `eval-defun' that's affected by
17995 `lexical-binding' (bug#8460).
17997 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17999 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18000 bidi redisplay when a line includes both an image and is truncated.
18002 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18004 Fix minor problems found by static checking.
18005 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18006 (elsz): Now a signed constant, not a size_t var. We prefer signed
18007 types to unsigned, to avoid integer comparison confusion. Without
18008 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18009 "cannot optimize loop, the loop counter may overflow", a symptom
18011 * indent.c (Fvertical_motion): Mark locals as initialized.
18012 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18014 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18016 * search.c (Fre_search_backward): Mention `case-fold-search' in
18017 all the re_search_* functions (bug#8138).
18019 * keyboard.c (Fopen_dribble_file): Document when the file is

18032 bidi_it->string.schars.
18033 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to

18037 buffer position was specified. Initialize paragraph_embedding to
18039 (reseat_to_string): Initialize the bidi iterator.
18040 (display_string): If we need to ignore text properties of
18041 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18042 original value of -1 will not work with bidi.)
18043 (compute_display_string_pos): First arg is now struct
18044 `text_pos *'; all callers changed. Support display properties on
18046 (compute_display_string_end): Support display properties on Lisp
18048 (init_iterator, reseat_1, reseat_to_string): Initialize the
18049 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18050 when iterating on a string not from display properties).
18051 (compute_display_string_pos, compute_display_string_end):
18052 Fix calculation of the object to scan. Fixes an error when using
18054 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18055 base_level_stop; instead, set base_level_stop to BEGV.
18056 Fixes crashes in vertical-motion.
18057 (next_element_from_buffer): Improve commentary for when
18058 the iterator is before prev_stop.
18059 (init_iterator): Initialize bidi_p from the default value of
18060 bidi-display-reordering, not from buffer-local value. Use the
18061 buffer-local value only if initializing for buffer iteration.
18062 (handle_invisible_prop): Support invisible properties on strings
18063 that are being bidi-reordered.
18064 (set_iterator_to_next): Support bidi reordering of C strings and
18066 (next_element_from_string): Support bidi reordering of Lisp

18070 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18071 (init_iterator): Don't initialize it->bidi_p for strings
18073 (reseat_to_string): Initialize it->bidi_p for strings here.
18074 (next_element_from_string, next_element_from_c_string)
18075 (next_element_from_buffer): Add xassert's for correspondence

18080 character that is not the first one in the visual order.
18081 (get_visually_first_element): New function, refactored from common
18082 parts of next_element_from_buffer, next_element_from_string, and
18083 next_element_from_c_string.
18084 (tool_bar_lines_needed, redisplay_tool_bar)
18085 (display_menu_bar): Force left-to-right direction. Add a FIXME
18086 comment for making that be controlled by a user option.
18087 (push_it, pop_it): Save and restore the state of the
18088 bidi iterator. Save and restore the bidi_p flag.
18089 (pop_it): Iterate out of display property for string iteration as

18092 (handle_single_display_spec): Set up it->bidi_it for iteration
18093 over a display string, and call bidi_init_it.
18094 (handle_single_display_spec, next_overlay_string)
18095 (get_overlay_strings_1, push_display_prop): Set up the bidi
18096 iterator for displaying display or overlay strings.
18097 (forward_to_next_line_start): Don't use the shortcut if
18099 (back_to_previous_visible_line_start): If handle_display_prop
18100 pushed the iterator stack, restore the internal state of the bidi
18101 iterator by calling bidi_pop_it same number of times.
18102 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18103 and we are bidi-iterating, don't decrement the iterator position;
18104 instead, set the first_elt flag in the bidi iterator, to produce
18106 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18107 (push_display_prop): xassert that we are iterating a buffer.
18108 (push_it, pop_it): Save and restore paragraph_embedding member.
18109 (handle_single_display_spec, next_overlay_string)
18110 (get_overlay_strings_1, reseat_1, reseat_to_string)
18111 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18112 correctly. Don't assume unibyte strings are not bidi-reordered.
18113 (compute_display_string_pos)
18114 (compute_display_string_end): Fix handling the case of C string.
18115 (push_it, pop_it): Save and restore from_disp_prop_p.

18120 popping after iteration over a string that came from a display
18121 property. Fix a typo in popping stretch info. Add an assertion
18122 for verifying that the iterator position is in sync with the bidi
18124 (handle_single_display_spec, get_overlay_strings_1)

18138 (try_scrolling, redisplay_window, display_line): Use them when
18139 saving a temporary copy of the iterator and restoring it back.
18140 (back_to_previous_visible_line_start, reseat_1)

18142 (move_it_in_display_line_to): If iterator ended up at
18143 EOL, but we never saw any buffer positions smaller than
18144 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
18145 motion in bidi-reordered lines.

18147 immediately before the call to set_iterator_to_next. Fixes cursor
18148 motion in bidi-reordered lines with stretch glyphs and strings
18149 displayed in margins. (Bug#8133) (Bug#8867)
18150 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
18152 (pos_visible_p): Support positions in bidi-reordered lines.
18153 Save and restore bidi cache.
18155 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
18156 (bidi_paragraph_info): Delete unused struct.
18157 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
18158 (bidi_cache_start): New variable.

18174 Support iteration over a string.
18175 (bidi_set_sor_type, bidi_resolve_explicit_1)
18176 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
18177 can now be zero (for strings); special values 0 and -1 were
18178 changed to -1 and -2, respectively.
18179 (bidi_char_at_pos): New function.
18180 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

18208 * dispextern.h (struct bidi_string_data): New structure.
18209 (struct bidi_it): New member `string'. Make flag members be 1-bit

18268 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
18269 The old code sometimes used this field without initializing it.
18271 * alloc.c (gc_sweep): Don't read past end of array.
18272 In theory, the old code could also have corrupted Emacs internals,
18273 though it'd be very unlikely.

18536 (clone_per_buffer_values): Don't assume that

18538 This isn't true in general, and it's particularly not true
18539 if Emacs is configured with --with-wide-int.
18540 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

18577 Random fixes. E.g., (random) never returned negative values.
18578 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18579 subseconds part to the entropy, as that's a bit more random.
18580 Prefer signed to unsigned, since the signedness doesn't matter and
18581 in general we prefer signed. When given a limit, use a
18582 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18583 latter isn't right if USE_2_TAGS_FOR_INTS.
18584 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18585 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18597 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18598 This is more efficient than Ffile_directory_p and avoids a minor race.
18600 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18602 * buffer.c (Foverlay_put): Say what the return value is
18605 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18606 is a directory before asking whether to use the file name

18609 error be more correct.
18611 * fns.c (Frequire): Remove the mention of the .gz files, since
18612 that's installation-specific, but keep the mention of

18625 Qgnutls_bootprop_verify_error (which is no longer used).
18627 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18628 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18629 Also (re)move comments that are misplaced or no longer relevant.

18658 * lread.c (syms_of_lread): Mention single symbols defined by
18659 `defvar' or `defconst' (bug#7154).
18661 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18662 (Frequire): Mention get-load-suffixes.

18730 * eval.c (struct backtrace): Simplify and port the data structure.
18731 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18732 signed bit field, as this assumption is not portable and it makes
18733 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18734 "char debug_on_exit : 1" as this is not portable either; instead,
18735 use the portable "unsigned int debug_on_exit : 1". Remove unused
18736 member evalargs. Remove obsolete comments about cc bombing out.
18738 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18810 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18811 and use min_width/height from frames size_hint to set
18812 min_width/height (Bug#8919).

18904 * print.c (printchar, strout): Check for string overflow.
18905 (PRINTPREPARE, printchar, strout):
18906 Don't set size unless allocation succeeds.
18908 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18909 for sizes. Check for string overflow more accurately.

18913 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18914 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18920 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18922 * lread.c: Integer overflow fixes.
18923 (read_integer): Radix is now EMACS_INT, not int,
18924 to improve quality of diagnostics for out-of-range radices.
18925 Calculate buffer size correctly for out-of-range radices.
18926 (read1): Check for integer overflow in radices, and in
18927 read-circle numbers.
18928 (read_escape): Avoid int overflow.
18929 (Fload, openp, read_buffer_size, read1)
18930 (substitute_object_recurse, read_vector, read_list, map_obarray):

18946 2011-06-22 Leo Liu <sdl.web@gmail.com>
18948 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18949 Move to minibuffer.el.
18951 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18953 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18954 The following patches are for when GLYPH_DEBUG && !XASSERT.
18955 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18956 * dispnew.c (flush_stdout):
18957 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18958 Mark as externally visible.
18959 * dispnew.c (check_window_matrix_pointers): Now static.

18968 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18970 (debug_method_add): Use va_list and vsprintf rather than relying
18971 on undefined behavior with wrong number of arguments.
18972 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18973 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18974 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18975 since we're not interested in debugging glyphs with old libraries.
18976 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18977 GCC 4.6.0's static checking.
18979 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18998 (.bitmaps_last, struct x_output.icon_bitmap):
18999 Use ptrdiff_t, not int, for bitmap indexes.

19014 (overlays_at, overlays_in): Check for size-calculation overflow.
19016 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19018 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19019 (x_session_initialize): Do not assume string length fits in int.
19021 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19022 This is unlikely, but can occur if DPI is outlandish.
19024 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19025 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

19028 * xrdb.c (magic_file_p, search_magic_path):
19029 Omit last arg SUFFIX; it was always 0. All callers changed.

19041 (display_mode_element): Don't assume strlen fits in int.
19043 * termcap.c: Don't assume sizes fit in int and never overflow.

19047 * minibuf.c (Fread_buffer):
19048 * lread.c (intern, intern_c_string):
19049 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

19067 Don't assume pid_t and time_t fit in unsigned long.
19068 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19069 (current_lock_owner): Prefer signed type for sizes.
19070 Use memcpy, not strncpy, where memcpy is what is really wanted.
19071 Don't assume (via atoi) that time_t and pid_t fit in int.
19072 Check for time_t and/or pid_t out of range, e.g., via a network share.
19073 Don't alloca where an auto var works fine.
19075 * fileio.c: Fix some integer overflow issues.

19100 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19102 * lread.c (invalid_syntax): Omit length argument.
19103 All uses changed. This doesn't fix a bug, but it simplifies the
19104 code away from its former Hollerith-constant appearance, and it's
19105 one less 'int' to worry about when looking at integer-overflow issues.
19106 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19108 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19109 This didn't break anything, but it didn't help either.
19110 It's confusing to put a bogus integer in a place where the actual
19111 value does not matter.
19112 (LIST_END_P): Remove unused macro and its bogus comment.
19113 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19115 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19116 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19118 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19119 We prefer signed types, and the value cannot exceed the EMACS_INT
19120 range anyway (because otherwise the length would not be representable).
19121 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19122 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19123 This avoids a GCC warning when WIDE_EMACS_INT.
19125 * indent.c (sane_tab_width): New function.
19126 (current_column, scan_for_column, Findent_to, position_indentation)
19127 (compute_motion): Use it. This is just for clarity.
19128 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19130 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19132 * lisp.h (lint_assume): New macro.
19133 * composite.c (composition_gstring_put_cache):
19134 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19136 * editfns.c, insdel.c:
19137 Omit unnecessary forward decls, to simplify future changes.
19139 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19141 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19143 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19144 Use much-faster test for byte-length change.
19145 Don't assume string byte-length fits in 'int'.
19146 Check that character arg fits in 'int'.
19147 (mapcar1): Declare byte as byte, for clarity.
19149 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19151 * fns.c (concat): Catch string overflow earlier.
19152 Do not rely on integer wraparound.
19154 * dispextern.h (struct it.overlay_strings_charpos)
19155 (struct it.selective): Now EMACS_INT, not int.
19156 * xdisp.c (forward_to_next_line_start)
19157 (back_to_previous_visible_line_start)
19158 (reseat_at_next_visible_line_start, next_element_from_buffer):
19159 Don't arbitrarily truncate the value of 'selective' to int.
19161 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19163 * composite.c: Don't truncate sizes to 'int'.
19164 (composition_gstring_p, composition_reseat_it)
19165 (composition_adjust_point): Use EMACS_INT, not int.
19166 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19167 not EMACS_UINT, for indexes.
19169 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19171 * buffer.c: Include <verify.h>.
19172 (struct sortvec.priority, struct sortstr.priority):
19173 Now EMACS_INT, not int.
19174 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19175 (struct sortstr.size, record_overlay_string)
19176 (struct sortstrlist.size, struct sortlist.used):
19177 Don't truncate size to int.
19178 (record_overlay_string): Check for size-calculation overflow.
19179 (init_buffer_once): Check at compile-time, not run-time.
19181 2011-06-22 Jim Meyering <meyering@redhat.com>
19183 Don't leak an XBM-image-sized buffer
19184 * image.c (xbm_load): Free the image buffer after using it.
19186 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19189 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19190 that Sun C diagnosed.
19191 * fns.c (secure_hash): Fix pointer signedness issue.
19192 * intervals.c (static_offset_intervals): New function.
19193 (offset_intervals): Use it.
19195 2011-06-21 Leo Liu <sdl.web@gmail.com>
19198 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19201 * fns.c (secure_hash): Rename from crypto_hash_function and change
19202 the first arg to accept symbols.
19203 (Fsecure_hash): New primitive.
19204 (syms_of_fns): New symbols.
19206 2011-06-20 Deniz Dogan <deniz@dogan.se>
19208 * process.c (Fset_process_buffer): Clarify return value in
19211 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19213 * dispnew.c (add_window_display_history): Use BVAR.
19215 * xdisp.c (debug_method_add): Use BVAR.
19216 (check_window_end, dump_glyph_matrix, dump_glyph)
19217 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19219 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19222 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19223 check till after the cache is created in init_frame_faces.
19225 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19227 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19229 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19231 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19232 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19233 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19235 Improve buffer-overflow checking (Bug#8873).
19236 * fileio.c (Finsert_file_contents):
19237 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19238 Remove the old (too-loose) buffer overflow checks.
19239 They weren't needed, since make_gap checks for buffer overflow.
19240 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19241 The old code merely checked for Emacs fixnum overflow, and relied
19242 on undefined (wraparound) behavior. The new code avoids undefined
19243 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19245 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19246 Tune. Don't use wider integers than needed. Don't use alloca.
19247 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19249 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19251 * insdel.c, lisp.h (buffer_overflow): New function.
19252 (insert_from_buffer_1, replace_range, replace_range_2):
19253 * insdel.c (make_gap_larger):
19254 * editfns.c (Finsert_char):
19255 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19257 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19259 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19261 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19263 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19264 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19266 * fileio.c: Don't assume EMACS_INT fits in off_t.
19267 (emacs_lseek): New static function.
19268 (Finsert_file_contents, Fwrite_region): Use it.
19269 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19271 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19273 * fns.c: Don't overflow int when computing a list length.
19274 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19275 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19276 truncation on 64-bit hosts. Check for QUIT every
19277 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19278 faster and is responsive enough.
19279 (Flength): Report an error instead of overflowing an integer.
19280 (Fsafe_length): Return a float if the value is not representable
19281 as a fixnum. This shouldn't happen except in contrived situations.
19282 (Fnthcdr, Fsort): Don't assume list length fits in int.
19283 (Fcopy_sequence): Don't assume vector length fits in int.
19285 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19286 (header_size, word_size): New constants.
19287 (allocate_vectorlike): Don't check size overflow here.
19288 (allocate_vector): Check it here instead, since this is the only
19289 caller of allocate_vectorlike that could cause overflow.
19290 Check that the new vector's length is representable as a fixnum.
19292 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19293 The previous code was bogus. For example, next_almost_prime (32)
19294 returned 39, which is undesirable as it is a multiple of 3; and
19295 next_almost_prime (24) returned 25, which is a multiple of 5 so
19296 why was the code bothering to check for multiples of 7?
19298 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19300 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19302 Variadic C functions now count arguments with ptrdiff_t.
19303 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19304 Back then I didn't know that the Emacs coding style prefers signed int.
19305 Also, in the meantime I found a few more instances where arguments
19306 were being counted with int, which may truncate counts on 64-bit
19307 machines, or EMACS_INT, which may be unnecessarily wide.
19308 * lisp.h (struct Lisp_Subr.function.aMANY)
19309 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19310 Arg counts are now ptrdiff_t, not size_t.
19311 All variadic functions and their callers changed accordingly.
19312 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19313 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19314 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19315 * callint.c (Fcall_interactively): Check arg count for overflow,
19316 to avoid potential buffer overrun. Use signed char, not 'int',
19317 for 'varies' array, so that we needn't bother to check its size
19318 calculation for overflow.
19319 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19320 * eval.c (apply_lambda):
19321 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19322 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19323 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19325 * callint.c (Fcall_interactively): Don't use index var as event count.
19327 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19328 * mem-limits.h (SIZE): Remove; no longer used.
19330 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19332 Remove unnecessary casts.
19333 * xterm.c (x_term_init):
19334 * xfns.c (x_set_border_pixel):
19335 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19336 These aren't needed now that we assume ANSI C.
19338 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19339 It's more likely to cause problems (due to unsigned overflow)
19342 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19344 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19346 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19348 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19350 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19352 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19354 GLYPH_CODE_FACE returns EMACS_INT, not int.
19355 * dispextern.h (merge_faces):
19356 * xfaces.c (merge_faces):
19357 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19358 Don't assume EMACS_INT fits in int.
19360 * character.h (CHAR_VALID_P): Remove unused parameter.
19361 * fontset.c, lisp.h, xdisp.c: All uses changed.
19363 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19365 * fns.c (concat): Minor tuning based on overflow analysis.
19366 This doesn't fix any bugs. Use int to hold character, instead
19367 of constantly refetching from Emacs object. Use XFASTINT, not
19368 XINT, for value known to be a character. Don't bother comparing
19369 a single byte to 0400, as it's always less.
19371 * floatfns.c (Fexpt):
19372 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19374 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19377 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19379 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19380 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19381 incorrectly succeed when S was a string, because 4294967386 was
19382 truncated before it was used.
19384 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19385 Otherwise, an out-of-range integer could cause undefined behavior
19388 * composite.c: Use int, not EMACS_INT, for characters.
19389 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19390 EMACS_INT, for values that are known to be in character range.
19391 This doesn't fix any bugs but is the usual style inside Emacs and
19392 may generate better code on 32-bit machines.
19394 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19395 This is for reasons similar to the recent CHAR_STRING fix.
19396 * charset.c (Fencode_char): Check that character arg is actually
19397 a character. Pass an int to ENCODE_CHAR.
19398 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19399 wider than 'int', as a compile-time check to prevent future regressions
19402 * character.c (char_string): Remove unnecessary casts.
19404 Make sure a 64-bit char is never passed to CHAR_STRING.
19405 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19406 by silently ignoring the top 32 bits, allowing some values
19407 that were far too large to be valid characters.
19408 * character.h: Include <verify.h>.
19409 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19410 arguments are no wider than unsigned, as a compile-time check
19411 to prevent future regressions in this area.
19413 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19414 (Fsubst_char_in_region):
19416 * xdisp.c (decode_mode_spec_coding):
19417 Adjust to CHAR_STRING's new requirement.
19418 * editfns.c (Finsert_char, Fsubst_char_in_region):
19419 * fns.c (concat): Check that character args are actually
19420 characters. Without this test, these functions did the wrong
19421 thing with wildly out-of-range values on 64-bit hosts.
19423 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19424 These casts should not be needed on 32-bit hosts, either.
19425 * keyboard.c (read_char):
19426 * lread.c (Fload): Remove casts to unsigned.
19428 * lisp.h (UNSIGNED_CMP): New macro.
19429 This fixes comparison bugs on 64-bit hosts.
19430 (ASCII_CHAR_P): Use it.
19431 * casefiddle.c (casify_object):
19432 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19433 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19434 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19435 * dispextern.h (FACE_FROM_ID):
19436 * keyboard.c (read_char): Use UNSIGNED_CMP.
19438 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19439 not to EMACS_INT, to avoid GCC warning.
19441 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19443 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19444 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19445 isn't needed on 32-bit machines.
19447 * buffer.c (Fgenerate_new_buffer_name):
19448 Use EMACS_INT for count, not int.
19449 (advance_to_char_boundary): Return EMACS_INT, not int.
19451 * data.c (Qcompiled_function): Now static.
19453 * window.c (window_body_lines): Now static.
19455 * image.c (gif_load): Rename local to avoid shadowing.
19457 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19458 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19459 * alloc.c (make_save_value): Integer argument is now of type
19460 ptrdiff_t, not int.
19461 (mark_object): Use ptrdiff_t, not int.
19462 * lisp.h (pD): New macro.
19463 * print.c (print_object): Use it.
19465 * alloc.c: Use EMACS_INT, not int, to count objects.
19466 (total_conses, total_markers, total_symbols, total_vector_size)
19467 (total_free_conses, total_free_markers, total_free_symbols)
19468 (total_free_floats, total_floats, total_free_intervals)
19469 (total_intervals, total_strings, total_free_strings):
19470 Now EMACS_INT, not int. All uses changed.
19471 (Fgarbage_collect): Compute overall total using a double, so that
19472 integer overflow is less likely to be a problem. Check for overflow
19473 when converting back to an integer.
19474 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19475 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19476 These were 'int' variables that could overflow on 64-bit hosts;
19477 they were never used, so remove them instead of repairing them.
19478 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19479 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19480 Previously, this ceilinged at INT_MAX, but that doesn't work on
19482 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19484 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19485 (allocate_vectorlike): Check for ptrdiff_t overflow.
19486 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19487 when a (possibly-narrower) signed value would do just as well.
19488 We prefer using signed arithmetic, to avoid comparison confusion.
19490 * alloc.c: Catch some string size overflows that we were missing.
19491 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19492 for convenience in STRING_BYTES_MAX.
19493 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19494 The definition here is exact; the one in lisp.h was approximate.
19495 (allocate_string_data): Check for string overflow. This catches
19496 some instances we weren't catching before. Also, it catches
19497 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19498 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19499 and ptrdiff_t and EMACS_INT are both 64 bits.
19501 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19502 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19503 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19505 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19507 * alloc.c (Fmake_string): Check for out-of-range init.
19509 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19511 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19513 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19515 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19516 xg_get_default_scrollbar_width.
19518 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19519 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19520 (style_changed_cb): Call update_theme_scrollbar_width and call
19521 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19522 all frames (Bug#8505).
19523 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19524 Call gtk_window_set_resizable if HAVE_GTK3.
19525 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19526 and height if HAVE_GTK3 (Bug#8505).
19527 (scroll_bar_width_for_theme): New variable.
19528 (update_theme_scrollbar_width): New function.
19529 (xg_get_default_scrollbar_width): Move code to
19530 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19531 (xg_initialize): Call update_theme_scrollbar_width.
19533 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19535 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19537 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19539 * frame.c (make_frame): Call other_buffer_safely instead of
19542 * window.c (temp_output_buffer_show): Call display_buffer with
19543 second argument Vtemp_buffer_show_specifiers and reset latter
19544 immediately after the call.

19999 (Fwindow_minibuffer_p): Move up in code and simplify.
20000 (Fset_frame_selected_window): Move here from frame.c.
20002 (Fselected_window, select_window, Fselect_window): Move up in
20003 code. Minor doc-string fixes.
20005 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
20007 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
20008 Do not assume that spare memory exists; that assumption is valid
20009 only if SYSTEM_MALLOC.
20010 (LARGE_REQUEST): New macro, so that the issue of large requests
20011 is separated from the issue of spare memory.
20013 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
20015 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

20041 New error handlers.
20042 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
20043 Obey Vx_select_enable_clipboard_manager. Catch errors in
20044 x_clipboard_manager_save (Bug#8779).
20045 (Vx_select_enable_clipboard_manager): New variable.
20046 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
20048 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
20050 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
20052 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20054 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
20055 in the current matrix if keep_current_p is non-zero.

20061 2011-06-03 Eli Zaretskii <eliz@gnu.org>
20063 Support bidi reordering of text covered by display properties.
20065 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
20066 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
20067 (bidi_cache_search, bidi_cache_iterator_state)
20068 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
20069 (bidi_level_of_next_char, bidi_move_to_visually_next):
20070 Support character positions inside a run of characters covered by a
20072 (bidi_paragraph_init, bidi_resolve_explicit_1)
20073 (bidi_level_of_next_char): Call bidi_fetch_char and
20074 bidi_fetch_char_advance instead of FETCH_CHAR and

20077 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
20079 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
20080 instead of using explicit *_CHAR codes.
20081 (bidi_resolve_explicit, bidi_resolve_weak):
20082 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
20083 bidirectional text is supported only in multibyte buffers.
20084 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
20085 it to initialize the frame_window_p member of struct bidi_it.
20086 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
20087 (bidi_resolve_explicit, bidi_resolve_weak)

20089 bidi_it->nchars is non-positive.
20090 (bidi_level_of_next_char): Don't try to lookup the cache for the
20091 next/previous character if nothing is cached there yet, or if we
20092 were just reseat()'ed to a new position.
20094 * xdisp.c (set_cursor_from_row): Set start and stop points
20095 according to the row's direction when priming the loop that looks
20096 for the glyph on which to display cursor.
20097 (single_display_spec_intangible_p): Function deleted.
20098 (display_prop_intangible_p): Reimplement to call
20099 handle_display_spec instead of single_display_spec_intangible_p.
20100 Accept 3 additional arguments needed by handle_display_spec.
20101 This fixes incorrect cursor motion across display property with complex
20102 values: lists, `(when COND...)' forms, etc.
20103 (single_display_spec_string_p): Support property values that are
20104 lists with the argument STRING its top-level element.
20105 (display_prop_string_p): Fix the condition for processing a
20106 property that is a list to be consistent with handle_display_spec.
20107 (handle_display_spec): New function, refactored from the
20108 last portion of handle_display_prop.
20109 (compute_display_string_pos): Accept additional argument
20110 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20111 value of a `display' property is a "replacing spec".
20112 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20113 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20114 the display property, but just return a value indicating whether
20115 the display property will replace the characters it covers.
20116 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20117 frame_window_p members of struct bidi_it.
20118 (compute_display_string_pos, compute_display_string_end):
20120 (push_it): Accept second argument POSITION, where pop_it should
20121 jump to continue iteration.
20122 (reseat_1): Initialize bidi_it.disp_pos.
20124 * keyboard.c (adjust_point_for_property): Adjust the call to
20125 display_prop_intangible_p to its new signature.
20127 * dispextern.h (struct bidi_it): New member frame_window_p.
20128 (bidi_init_it): Update prototypes.
20129 (display_prop_intangible_p): Update prototype.
20130 (compute_display_string_pos, compute_display_string_end):
20131 Declare prototypes.
20132 (struct bidi_it): New members nchars and disp_pos. ch_len is now
20135 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
20137 Malloc failure behavior now depends on size of allocation.
20138 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20139 * lisp.h: Change signatures accordingly.
20140 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20141 All callers changed. (Bug#8762)
20143 * gnutls.c: Use Emacs's memory allocators.
20144 Without this change, the gnutls library would invoke malloc etc.
20145 directly, which causes problems on non-SYNC_INPUT hosts, and which
20146 runs afoul of improving memory_full behavior. (Bug#8761)
20147 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20148 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20149 xfree instead of the default malloc, realloc, free.
20150 (Fgnutls_boot): No need to check for memory allocation failure,
20151 since xmalloc does that for us.
20153 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20154 * category.c (hash_get_category_set):
20155 * ccl.c (ccl_driver):
20156 * charset.c (Fdefine_charset_internal):

20167 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20168 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20169 * image.c (make_image, search_image_cache, lookup_image)
20170 (xpm_put_color_table_h):
20171 * lisp.h (struct Lisp_Hash_Table):
20172 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20173 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20174 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20175 * alloc.c (allocate_vectorlike):
20176 Check for overflow in vector size calculations.
20177 * ccl.c (ccl_driver):
20178 Check for overflow when converting EMACS_INT to int.
20179 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20180 need to be updated by these changes.
20181 * fns.c (make_hash_table, maybe_resize_hash_table):
20182 Check for integer overflow with large hash tables.
20183 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20184 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20185 (SXHASH_REDUCE): New macro.
20186 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20187 Use it instead of discarding useful hash info with large hash values.
20188 (sxhash_float): New function.
20189 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20190 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20191 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20192 Rewrite to use FIXNUM_BITS, as this simplifies things.
20193 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20194 Adjust signatures to match updated version of code.
20195 (consing_since_gc): Now EMACS_INT, since a single hash table can
20196 use more than INT_MAX bytes.
20198 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20200 Make it possible to build with GCC-4.6+ -O2 -flto.
20202 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20204 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20206 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20207 Call minibuffer-inactive-mode.
20209 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20211 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20212 Update dependencies.
20214 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20216 * data.c (init_data): Remove code for UTS, this system is not
20219 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20221 Don't force ./temacs to start in terminal mode.
20223 * frame.c (make_initial_frame): Initialize faces in all cases, not
20224 only when CANNOT_DUMP is defined.
20225 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20227 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20229 * dispnew.c (add_window_display_history): Use const for the string
20230 pointer. Remove declaration, not needed.
20232 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20234 Use 'inline', not 'INLINE'.
20235 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20236 * alloc.c, fontset.c (INLINE): Remove.
20237 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20238 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20239 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20240 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20241 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20243 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20245 Make it possible to run ./temacs.
20247 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20248 syms_of_callproc does the same thing. Remove test for
20249 "initialized", do it in the caller.
20250 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20252 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20254 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20255 (read_minibuf): Use get_minibuffer.
20256 (syms_of_minibuf): Use DEFSYM.
20257 (Qmetadata): New var.
20258 * data.c (Qbuffer): Don't make it static.
20259 (syms_of_data): Use DEFSYM.
20261 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20263 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20264 (CCL_CODE_MIN): New macro.
20266 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20268 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20270 * eval.c (Qdebug): Now static.
20271 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20272 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20273 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20275 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20277 * image.c: Various fixes to ImageMagick code comments.
20278 (Fimagemagick_types): Doc fix.
20280 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20282 Minor fixes prompted by GCC 4.6.0 warnings.
20284 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20286 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20287 (x_clipboard_manager_save_all): Move extern decl to ...
20288 * xterm.h: ... here, so that it can be checked for consistency.
20290 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20292 * xselect.c (x_clipboard_manager_save_frame)
20293 (x_clipboard_manager_save_all): New functions.
20294 (Fx_clipboard_manager_save): Lisp function deleted.
20296 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20297 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20299 * xterm.h: Update prototype.
20301 2011-05-28 William Xu <william.xwl@gmail.com>
20303 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20304 exiting (Bug#8239).
20306 2011-05-28 Jim Meyering <meyering@redhat.com>
20308 Avoid a sign-extension bug in crypto_hash_function.
20309 * fns.c (to_uchar): Define.
20310 (crypto_hash_function): Use it to convert some newly-signed
20311 variables to unsigned, to avoid sign-extension bugs. For example,
20312 without this change, (md5 "truc") would evaluate to
20313 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20314 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20315 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20317 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20319 Integer overflow fixes.
20321 * dbusbind.c: Serial number integer overflow fixes.
20322 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20323 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20324 to hold a serial number that is too large for a fixnum.
20325 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20326 Check for serial numbers out of range. Decode any serial number
20327 that was so large that it became a float. (Bug#8722)
20329 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20330 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20331 Use XFASTINT rather than XUINT when numbers are nonnegative.
20332 (xd_append_arg, Fdbus_method_return_internal):
20333 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20334 arguments, check that Lisp number is nonnegative, rather than
20335 silently wrapping negative numbers around. (Bug#8722)
20336 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20339 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20341 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20343 ccl: Add integer overflow checks.
20344 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20345 (IN_INT_RANGE): New macros.
20346 (ccl_driver): Use them to check for integer overflow when
20347 decoding a CCL program. Many of the new checks are whether XINT (x)
20348 fits in int; it doesn't always, on 64-bit hosts. The new version
20349 doesn't catch all possible integer overflows, but it's an
20350 improvement. (Bug#8719)
20352 * alloc.c (make_event_array): Use XINT, not XUINT.
20353 There's no need for unsigned here.
20355 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20356 This follows up to the 2011-05-06 change that substituted uintptr_t
20357 for EMACS_INT. This case wasn't caught back then.
20359 Rework Fformat to avoid integer overflow issues.
20360 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20361 now (part of C89). Include <verify.h>.
20362 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20363 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20364 (Fformat): Avoid the prepass trying to compute sizes; it was only
20365 approximate and thus did not catch overflow reliably. Instead, walk
20366 through the format just once, formatting and computing sizes as we go,
20367 checking for integer overflow at every step, and allocating a larger
20368 buffer as needed. Keep track separately whether the format is
20369 multibyte. Keep only the most-recently calculated precision, rather
20370 than them all. Record whether each argument has been converted to
20371 string. Use EMACS_INT, not int, for byte and char and arg counts.
20372 Support field widths and precisions larger than INT_MAX. Avoid
20373 sprintf's undefined behavior with conversion specifications such as %#d
20374 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20375 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20376 formatting out-of-range floating point numbers with int
20377 formats. (Bug#8668)
20379 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20381 * data.c: Avoid integer truncation in expressions involving floats.
20382 * data.c: Include <intprops.h>.
20383 (arith_driver): When there's an integer overflow in an expression
20384 involving floating point, convert the integers to floating point
20385 so that the resulting value does not suffer from catastrophic
20386 integer truncation. For example, on a 64-bit host (* 4
20387 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20388 Do not rely on undefined behavior after integer overflow.
20390 merge count_size_as_multibyte, parse_str_to_multibyte
20391 * character.c, character.h (count_size_as_multibyte):
20392 Rename from parse_str_to_multibyte; all uses changed.
20393 Check for integer overflow.
20394 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20395 since it's now a duplicate of the other. This is more of
20396 a character than a buffer op, so better that it's in character.c.
20397 * fns.c, print.c: Adjust to above changes.
20399 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20401 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20403 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20405 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20406 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20407 (x_clipboard_manager_save): Now static.
20408 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20410 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20411 (crypto_hash_function): Now static.
20412 Fix pointer signedness problems. Avoid unnecessary initializations.
20414 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20416 * termhooks.h (Vselection_alist): Make it terminal-local.
20418 * terminal.c (create_terminal): Initialize it.
20420 * xselect.c: Support for clipboard managers.
20421 (Vselection_alist): Move to termhooks.h as terminal-local var.
20422 (LOCAL_SELECTION): New macro.
20423 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20424 (symbol_to_x_atom): Remove gratuitous arg.
20425 (x_handle_selection_request, lisp_data_to_selection_data)
20426 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20427 (x_own_selection, x_get_local_selection, x_convert_selection):
20428 New arg, specifying work frame. Use terminal-local Vselection_alist.
20429 (some_frame_on_display): Delete unused function.
20430 (Fx_own_selection_internal, Fx_get_selection_internal)
20431 (Fx_disown_selection_internal, Fx_selection_owner_p)
20432 (Fx_selection_exists_p): New optional frame arg.
20433 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20434 (x_handle_selection_clear): Don't treat other terminals with the
20435 same keyboard specially. Use the terminal-local Vselection_alist.
20436 (x_clear_frame_selections): Use Frun_hook_with_args.
20438 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20440 * xterm.h: Add support for those atoms.
20442 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20444 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20445 (converted_selections, conversion_fail_tag): New global variables.
20446 (x_selection_request_lisp_error): Free the above.
20447 (x_get_local_selection): Remove unnecessary code.
20448 (x_reply_selection_request): Args changed; handle arbitrary array
20449 of converted selections stored in converted_selections.
20450 Separate the XChangeProperty and SelectionNotify steps.
20451 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20452 (x_convert_selection): New function.
20453 (x_handle_selection_event): Simplify.
20454 (x_get_foreign_selection): Don't ignore incoming requests while
20455 waiting for an answer; this will fail when we implement
20456 SAVE_TARGETS, and seems unnecessary anyway.
20457 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20458 (Vx_sent_selection_functions): Doc fix.
20460 2011-05-26 Leo Liu <sdl.web@gmail.com>
20462 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20464 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20466 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20468 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20469 for fringe update if it has periodic bitmap.
20470 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20471 and fringe_bitmap_periodic_p.
20473 * fringe.c (get_fringe_bitmap_data): New function.
20474 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20475 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20476 row. Mark glyph row for fringe update if periodicity changed.
20478 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20479 for fringe update unless it has periodic bitmap.
20481 2011-05-25 Kenichi Handa <handa@m17n.org>
20483 * xdisp.c (get_next_display_element): Set correct it->face_id for
20484 a static composition.
20486 2011-05-24 Leo Liu <sdl.web@gmail.com>
20489 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20491 * fns.c (crypto_hash_function, Fsha1): New function.
20492 (Fmd5): Use crypto_hash_function.
20493 (syms_of_fns): Add Ssha1.
20495 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20497 * gnutls.c: Remove unused macros.
20498 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20499 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20500 Remove macros that are defined and never used.
20501 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20503 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20505 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20506 (Fx_get_selection_internal): Minor cleanup.
20507 (Fx_own_selection_internal): Rename arguments for consistency with
20510 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20512 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20514 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20516 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20518 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20520 * dispnew.c (scrolling_window): Don't exclude the case that the
20521 last enabled row in the desired matrix touches the bottom boundary.
20523 2011-05-21 Glenn Morris <rgm@gnu.org>
20525 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20526 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20527 and add some more files.
20529 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20531 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20532 report_file_error introduced by the change from 2011-05-07.
20534 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20536 * systime.h (Time): Define only if emacs is defined.
20537 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20538 where the include path doesn't have X11/X.h by default. See
20539 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20541 2011-05-20 Kenichi Handa <handa@m17n.org>
20543 * composite.c (find_automatic_composition): Fix previous change.
20545 2011-05-20 Glenn Morris <rgm@gnu.org>
20547 * lisp.mk: New file, split from Makefile.in.
20548 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20549 (shortlisp): Remove.
20550 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20552 2011-05-19 Glenn Morris <rgm@gnu.org>
20554 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20555 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20556 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20557 (lisp): Set the order to that of loadup.el.
20558 (shortlisp): Make it a copy of $lisp.
20559 (SOME_MACHINE_LISP): Remove.
20560 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20561 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20563 2011-05-18 Kenichi Handa <handa@m17n.org>
20565 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20566 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20567 (find_automatic_composition): Mostly rewrite for efficiency.
20569 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20571 * makefile.w32-in: Update dependencies.
20573 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20575 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20576 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20578 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20580 Fix some integer overflow issues, such as string length overflow.
20582 * insdel.c (count_size_as_multibyte): Check for string overflow.
20584 * character.c (lisp_string_width): Check for string overflow.
20585 Use EMACS_INT, not int, for string indexes and lengths; in
20586 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20587 the resulting string length overflows an EMACS_INT; instead,
20588 report a string overflow if no precision given. When checking for
20589 precision exhaustion, use a check that cannot possibly have
20590 integer overflow. (Bug#8675)
20591 * character.h (lisp_string_width): Adjust to new signature.
20593 * alloc.c (string_overflow): New function.
20594 (Fmake_string): Use it. This doesn't change behavior, but saves
20595 a few bytes and will simplify future changes.
20596 * character.c (string_escape_byte8): Likewise.
20597 * lisp.h (string_overflow): New decl.
20599 Fixups, following up to the user-interface timestamp change.
20600 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20601 for UI timestamps, instead of unsigned long.
20602 * msdos.c (mouse_get_pos): Likewise.
20603 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20604 * w32gui.h (Time): Define by including "systime.h" rather than by
20605 declaring it ourselves. (Bug#8664)
20607 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20608 * image.c (clear_image_cache): Likewise.
20610 * term.c (term_mouse_position): Don't assume time_t wraparound.
20612 Be more systematic about user-interface timestamps.
20613 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20614 and sometimes 'EMACS_UINT', to represent these timestamps.
20615 This change causes it to use 'Time' uniformly, as that's what X uses.
20616 This makes the code easier to follow, and makes it easier to catch
20617 integer overflow bugs such as Bug#8664.
20618 * frame.c (Fmouse_position, Fmouse_pixel_position):
20619 Use Time, not unsigned long, for user-interface timestamps.
20620 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20621 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20622 * keyboard.h (last_event_timestamp): Likewise.
20623 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20624 * menu.h (xmenu_show): Likewise.
20625 * term.c (term_mouse_position): Likewise.
20626 * termhooks.h (struct input_event.timestamp): Likewise.
20627 (struct terminal.mouse_position_hook): Likewise.
20628 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20629 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20630 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20631 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20632 what it was before.
20633 * menu.h, termhooks.h: Include "systime.h", for Time.
20635 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20636 Don't assume that the difference between two unsigned long values
20637 can fit into an integer. At this point, we know button_down_time
20638 <= event->timestamp, so the difference must be nonnegative, so
20639 there's no need to cast the result if double-click-time is
20640 nonnegative, as it should be; check that it's nonnegative, just in
20641 case. This bug is triggered when events are more than 2**31 ms
20642 apart (about 25 days). (Bug#8664)
20644 * xselect.c (last_event_timestamp): Remove duplicate decl.
20645 (x_own_selection): Remove needless cast to unsigned long.
20647 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20648 that always fit in int. Use a sentinel instead of a counter, to
20649 avoid a temp and to allay GCC's concerns about possible int overflow.
20650 * frame.h (struct frame): Use int for menu_bar_items_used
20651 instead of EMACS_INT, since it always fits in int.
20653 * menu.c (grow_menu_items): Check for int overflow.
20655 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20657 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20658 Before, the code was not consistent. These values cannot exceed
20659 2**31 - 1 so there's no need to make them unsigned.
20660 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20661 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20662 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20664 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20666 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20667 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20668 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20669 presumably because the widths might not match.
20671 * window.c (size_window): Avoid needless test at loop start.
20673 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20675 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20677 2011-05-12 Drew Adams <drew.adams@oracle.com>
20679 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20681 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20683 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20684 `width' to `bar_area_x' and `bar_area_width', respectively.
20685 (x_scroll_run): Take account of fringe background extension.
20687 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20688 Rename local vars `left' and `width' to `bar_area_x' and
20689 `bar_area_width', respectively.
20690 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20691 background extension.
20693 2011-05-10 Jim Meyering <meyering@redhat.com>
20695 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20697 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20699 * image.c (Finit_image_library): Return t for built-in image types,
20700 like pbm and xbm. (Bug#8640)
20702 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20704 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20706 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20708 * w32console.c (Fset_screen_color): Doc fix.
20709 (Fget_screen_color): New function.
20710 (syms_of_ntterm): Defsubr it.
20712 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20713 unlink the temporary file if Fcall_process didn't create it in the
20715 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20716 child process will be redirected to a file specified with `:file'.
20717 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20718 cue to call_process_cleanup not to close that handle.
20720 2011-05-07 Ben Key <bkey76@gmail.com>
20722 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20723 one of two shell specific rules, either bootstrap-temacs-CMD or
20724 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20725 to the previous implementation of the bootstrap-temacs rule.
20726 The bootstrap-temacs-CMD rule is similar to the previous
20727 implementation of the bootstrap-temacs rule except that it
20728 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20731 These changes, along with some changes to nt/configure.bat,
20732 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20733 earlier fix to add support for --cflags and --ldflags options
20734 that include quotes so that it works whether make uses cmd or
20737 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20739 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20740 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20742 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20743 a string. Handle both cases.
20744 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20745 (Fdbus_register_method): Use Qinvalid_function.
20747 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20749 * makefile.w32-in: Update dependencies.
20750 (LISP_H): Add inttypes.h and stdin.h.
20751 (PROCESS_H): Add unistd.h.
20753 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20755 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20756 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20758 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20760 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20762 * term.c (vfatal): Remove stray call to va_end.
20763 It's not needed and the C Standard doesn't allow it here anyway.
20765 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20766 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20768 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20771 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20773 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20775 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20777 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20779 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20781 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20782 * charset.c (Fdefine_charset_internal): Don't initialize
20783 charset.code_space[15]. The value was garbage, on hosts with
20784 32-bit int (Bug#8600).
20786 * lread.c (read_integer): Be more consistent with string-to-number.
20787 Use string_to_number to do the actual conversion; this avoids
20788 rounding errors and fixes some other screwups. Without this fix,
20789 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20790 (digit_to_number): Move earlier, for benefit of read_integer.
20791 Return -1 if the digit is out of range for the base, -2 if it is
20792 not a digit in any supported base. (Bug#8602)
20794 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20796 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20797 to match comment at start of function. This also removes a
20798 GCC warning about overflow in a 32+64-bit port.
20800 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20802 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20803 Reported by Stefan Monnier in
20804 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20805 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20806 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20808 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20809 (EMACS_UINTPTR): Likewise, with uintptr_t.
20811 * lisp.h: Prefer 64-bit EMACS_INT if available.
20812 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20813 on 32-bit hosts that have 64-bit int, so that they can access
20815 However, temporarily disable this change unless the temporary
20816 symbol WIDE_EMACS_INT is defined.
20818 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20820 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20821 This removes an assumption that EMACS_INT and long are the same
20822 width as pointers. The assumption is true for Emacs porting targets
20823 now, but we want to make other targets possible.
20824 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20825 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20826 In the rest of the code, change types of integers that hold casted
20827 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20828 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20829 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20830 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20831 No need to cast type when ORing.
20832 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20833 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20834 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20835 assume EMACS_INT is the same width as char *.
20836 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20837 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20838 Remove no-longer-needed casts.
20839 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20840 (xg_tool_bar_help_callback, xg_make_tool_item):
20841 Use EMACS_INTPTR to hold an integer
20842 that will be cast to void *; this can avoid a GCC warning
20843 if EMACS_INT is not the same width as void *.
20844 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20845 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20846 (current_message_1, set_message_1):
20847 Use a local to convert to proper width without a cast.
20848 * xmenu.c (dialog_selection_callback): Likewise.
20850 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20851 Also, don't assume VALBITS / RAND_BITS is less than 5,
20852 and don't rely on undefined behavior when shifting a 1 left into
20854 * lisp.h (get_random): Change signature to match.
20856 * lread.c (hash_string): Use size_t, not int, for hash computation.
20857 Normally we prefer signed values; but hashing is special, because
20858 it's better to use unsigned division on hash table sizes so that
20859 the remainder is nonnegative. Also, size_t is the natural width
20860 for hashing into memory. The previous code used 'int', which doesn't
20861 retain enough info to hash well into very large tables.
20862 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20864 * dbusbind.c: Don't possibly lose pointer info when converting.
20865 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20866 Use XPNTR rather than XHASH, so that the high-order bits of
20867 the pointer aren't lost when converting through void *.
20869 * eval.c (Fautoload): Don't double-shift a pointer.
20871 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

20905 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20906 Remove unused parameter `fildes'.
20907 * process.c (read_process_output, send_process): Don't pass it.
20909 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20911 Fix previous change: the library cache is defined in w32.c.
20912 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20913 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

20955 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20956 instead of gnutls_record_check_pending.
20958 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20960 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20962 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20963 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20966 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20968 * xterm.c (x_set_frame_alpha): Do not set property on anything

21005 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21007 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21008 rather than `XVECTOR (FOO)->size'.
21010 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21011 inttypes.h, as a gnulib replacement is used if it not available in
21014 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21016 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21017 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21018 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21020 * coding.c (coding_alloc_by_realloc): Error out if destination
21021 will grow beyond MOST_POSITIVE_FIXNUM.
21022 (decode_coding_emacs_mule): Abort if there isn't enough place in
21023 charbuf for the composition carryover bytes. Reserve an extra

21074 * makefile.w32-in: Update dependencies.
21076 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21078 Improve `doprnt' and its usage. (Bug#8545)
21079 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21080 `format_end'. Remove support for %l as a conversion specifier.
21081 Don't use xrealloc. Improve diagnostics when the %l size modifier
21082 is used. Update the commentary.
21084 * eval.c (verror): Simplify calculation of size_t.
21086 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21089 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21091 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21094 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21096 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21097 This makes this file independent of the recent pseudovector change.
21099 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21101 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21103 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21104 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21105 Remove unused local.
21106 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21108 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21109 GCC 4.6.0 optimizes based on type-based alias analysis.
21110 For example, if b is of type struct buffer * and v of type struct
21111 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21112 != &v->size, and therefore "v->size = 1; b->size = 2; return
21113 v->size;" must therefore return 1. This assumption is incorrect
21114 for Emacs, since it type-puns struct Lisp_Vector * with many other
21115 types. To fix this problem, this patch adds a new type struct
21116 vectorlike_header that documents the constraints on layout of vectors
21117 and pseudovectors, and helps optimizing compilers not get fooled
21118 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21119 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21120 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21122 (XSETPVECTYPE): Rewrite in terms of new macro.
21123 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21124 This is a bit clearer, and further avoids the possibility of
21125 undesirable aliasing.
21126 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21127 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21128 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21129 since Lisp_Subr is a special case (no "next" field).
21130 (ASIZE): Now uses header.size rather than size.
21131 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21132 to avoid the hassle of writing XVECTOR (foo)->header.size.
21133 (struct vectorlike_header): New type.
21134 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21135 object, to help avoid aliasing.
21136 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21137 (SUBRP): Likewise, since Lisp_Subr is a special case.
21138 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21139 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21140 (struct Lisp_Hash_Table): Combine first two members into a single
21141 struct vectorlike_header member. All uses of "size" and "next" members
21142 changed to be "header.size" and "header.next".
21143 * buffer.h (struct buffer): Likewise.
21144 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21145 * frame.h (struct frame): Likewise.
21146 * process.h (struct Lisp_Process): Likewise.
21147 * termhooks.h (struct terminal): Likewise.
21148 * window.c (struct save_window_data, struct saved_window): Likewise.
21149 * window.h (struct window): Likewise.
21150 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21151 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21152 * buffer.c (init_buffer_once): Likewise.
21153 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21155 * process.c (Fformat_network_address): Use local var for size,
21158 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21160 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21161 * data.c (atof): Remove decl; no longer used or needed.
21162 (digit_to_number): Move to lread.c.
21163 (Fstring_to_number): Use new string_to_number function, to be
21164 consistent with how the Lisp reader treats infinities and NaNs.
21165 Do not assume that floating-point numbers represent EMACS_INT
21166 without losing information; this is not true on most 64-bit hosts.
21167 Avoid double-rounding errors, by insisting on integers when
21168 parsing non-base-10 numbers, as the documentation specifies.
21169 * lisp.h (string_to_number): New decl, replacing ...
21170 (isfloat_string): Remove.
21171 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21172 (read1): Do not accept +. and -. as integers; this
21173 appears to have been a coding error. Similarly, do not accept
21174 strings like +-1e0 as floating point numbers. Do not report
21175 overflow for integer overflows unless the base is not 10 which
21176 means we have no simple and reliable way to continue.
21177 Break out the floating-point parsing into a new
21178 function string_to_number, so that Fstring_to_number parses
21179 floating point numbers consistently with the Lisp reader.
21180 (digit_to_number): Move here from data.c. Make it static inline.
21181 (E_CHAR, EXP_INT): Remove, replacing with ...
21182 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21183 (string_to_number): New function, replacing isfloat_string.
21184 This function checks for valid syntax and produces the resulting
21185 Lisp float number too. Rework it so that string-to-number
21186 no longer mishandles examples like "1.0e+". Use strtoumax,
21187 so that overflow for non-base-10 numbers is reported only when
21188 there's no portable and simple way to convert to floating point.
21190 * textprop.c (set_text_properties_1): Rewrite for clarity,
21191 and to avoid GCC warning about integer overflow.
21193 * intervals.h (struct interval): Use EMACS_INT for members
21194 where EMACS_UINT might cause problems. See
21195 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21196 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21197 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21199 (offset_intervals): Tell GCC not to worry about length overflow
21200 when negating a negative length.
21202 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21203 (overrun_check_free): Likewise.
21205 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21206 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21209 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21210 (gnutls_make_error): Rename local to avoid shadowing.
21211 (gnutls_emacs_global_deinit): ifdef out; not used.
21212 (Fgnutls_boot): Use const for pointer to readonly storage.
21213 Comment out unused local. Fix pointer signedness problems.
21215 * lread.c (openp): Don't stuff size_t into an 'int'.
21216 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21217 about possible signed overflow.
21219 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21220 (GDK_KEY_g): Don't define if already defined.
21221 (xg_prepare_tooltip): Avoid pointer signedness problem.
21222 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21224 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21225 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21227 * xfns.c (Fx_window_property): Simplify a bit,
21228 to make a bit faster and to avoid GCC 4.6.0 warning.
21229 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21231 * fns.c (internal_equal): Don't assume size_t fits in int.
21233 * alloc.c (compact_small_strings): Tighten assertion a little.
21235 Replace pEd with more-general pI, and fix some printf arg casts.
21236 * lisp.h (pI): New macro, generalizing old pEd macro to other
21237 conversion specifiers. For example, use "...%"pI"d..." rather
21238 than "...%"pEd"...".
21239 (pEd): Remove. All uses replaced with similar uses of pI.
21240 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21241 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21242 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21243 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21244 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21245 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21246 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21248 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21249 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21250 * print.c (safe_debug_print, print_object): Likewise.
21251 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21253 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21254 avoiding the 0 flag, which is not portable.
21255 * process.c (Fmake_network_process): Use pI to avoid cast.
21256 * region-cache.c (pp_cache): Likewise.
21257 * xdisp.c (decode_mode_spec): Likewise.
21258 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21259 behavior on 64-bit hosts with printf arg.
21260 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.

21262 (x_get_window_property): Don't truncate byte count to an 'int'
21265 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21266 here, since it parses constructs like leading '-' and spaces,
21267 which are not wanted; and it overflows with large numbers.
21268 Instead, simply match F[0-9]+, which is what is wanted anyway.
21270 * alloc.c: Remove unportable assumptions about struct layout.
21271 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21272 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21273 (allocate_vectorlike, make_pure_vector): Use the new macros,
21274 plus offsetof, to remove unportable assumptions about struct layout.
21275 These assumptions hold on all porting targets that I know of, but
21276 they are not guaranteed, they're easy to remove, and removing them
21277 makes further changes easier.
21279 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21280 This doesn't fix a bug but makes the code clearer.
21281 (string_overrun_cookie): Now const. Use initializers that
21282 don't formally overflow signed char, to avoid warnings.
21283 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21284 can cause Emacs to crash when string overrun checking is enabled.
21285 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21286 multiple of sizeof (EMACS_INT); it need not be, if
21287 alignof(EMACS_INT) < sizeof (EMACS_INT).
21288 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

21323 * doprnt.c (doprnt): Document the set of format control sequences
21324 supported by the function. Use SAFE_ALLOCA instead of always
21327 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21328 is one byte too soon. Don't use xrealloc; instead xfree and

21340 docstring. Start callback support.
21341 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21342 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21446 codepoint of an invalid character, to avoid displaying a bogus
21449 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21450 `error', not SYMBOL_NAME itself.
21452 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21453 character arguments to `error'.
21455 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21456 to `error' in error message about FINAL_CHAR argument. Make sure
21457 FINAL_CHAR is a character, and use %c when it is passed as
21458 argument to `error'.
21460 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21462 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21464 * w32.c: Include <time.h>.

21528 * dispextern.h (struct redisplay_interface): Rename param
21529 to avoid shadowing.
21530 * termhooks.h (struct terminal): Likewise.

21647 * nsfont.m: Fixed bugs in ns_get_family and
21648 ns_descriptor_to_entity that were caused by using free to
21649 deallocate memory blocks that were allocated by xmalloc (via
21650 xstrdup). This caused Emacs to crash when compiled with
21651 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21652 --enable-checking=xmallocoverrun). xfree is now used to
21653 deallocate these memory blocks.

21669 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21670 (emacs_read, emacs_write): Use it.
21671 * process.c (send_process): Adjust to the new signatures of
21672 emacs_write and emacs_gnutls_write. Do not attempt to store

22151 is outside the buffer's accessible region. (Bug#8468)
22153 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22155 Fix write-region and its subroutines for buffers > 2GB.
22156 * fileio.c (a_write, e_write): Modify declaration of arguments and
22157 local variables to support buffers larger than 2GB.
22158 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22160 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22161 argument, local variables, and return value.
22163 * lisp.h: Update prototypes of emacs_write and emacs_read.
22165 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22167 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22169 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22171 Fix more problems found by GCC 4.6.0's static checks.
22173 * xdisp.c (vmessage): Use a better test for character truncation.
22175 * charset.c (load_charset_map): <, not <=, for optimization,
22176 and to avoid potential problems with integer overflow.
22177 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22178 * casetab.c (set_identity, shuffle): Likewise.
22179 * editfns.c (Fformat): Likewise.
22180 * syntax.c (skip_chars): Likewise.
22182 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22183 This also lets GCC 4.6.0 generate slightly better loop code.
22185 * callint.c (Fcall_interactively): <, not <=, for optimization.
22186 (Fcall_interactively): Count the number of arguments produced,
22187 not the number of arguments given. This is simpler and lets GCC
22188 4.6.0 generate slightly better code.
22190 * ftfont.c: Distingish more carefully between FcChar8 and char.
22191 The previous code passed unsigned char * to a functions like
22192 strlen and xstrcasecmp that expect char *, which does not
22193 conform to the C standard.
22194 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22195 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22196 char * when the C standard requires it.
22198 * keyboard.c (read_char): Remove unused var.
22200 * eval.c: Port to Windows vsnprintf (Bug#8435).
22201 Include <limits.h>.
22202 (SIZE_MAX): Define if the headers do not.
22203 (verror): Do not give up if vsnprintf returns a negative count.
22204 Instead, grow the buffer. This ports to Windows vsnprintf, which
22205 does not conform to C99. Problem reported by Eli Zaretskii.
22206 Also, simplify the allocation scheme, by avoiding the need for
22207 calling realloc, and removing the ALLOCATED variable.
22209 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22211 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22212 But keep the doprint source code for now, as we might revamp it
22213 and use it again (Bug#8435).
22214 * lisp.h (doprnt): Remove.
22215 * Makefile.in (base_obj): Remove doprnt.o.
22216 * deps.mk (doprnt.o): Remove.
22218 error: Print 32- and 64-bit integers portably (Bug#8435).
22219 Without this change, on typical 64-bit hosts error ("...%d...", N)
22220 was used to print both 32- and 64-bit integers N, which relied on
22221 undefined behavior.
22222 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22223 * lisp.h (error, verror): Mark as printf-like functions.
22224 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22225 Report overflow in size calculations when allocating printf buffer.
22226 Do not truncate output string at its first null byte.
22227 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22228 Truncate the output at a character boundary, since vsnprintf does not
22230 * charset.c (check_iso_charset_parameter): Convert internal
22231 character to string before calling 'error', since %c now has the
22233 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22234 overflow when computing char to be passed to 'error'. Do not
22235 pass Lisp_Object to 'error'; pass the integer instead.
22236 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22237 formatted with plain %d.
22239 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22241 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22243 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22245 * xterm.c (x_catch_errors): Remove duplicate declaration.
22247 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22249 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22251 2011-04-10 Jim Meyering <meyering@redhat.com>
22253 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22254 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22255 return ssize_t not "int", and use size_t as the buffer length.
22256 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22257 * gnutls.h: Update declarations.
22258 * process.c (read_process_output): Use ssize_t, to match.
22259 (send_process): Likewise.
22261 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22263 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22265 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22267 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22268 Use unsigned char, to match FcChar8 type definition.
22270 * xterm.c (handle_one_xevent):
22271 * xmenu.c (create_and_show_popup_menu):
22272 * xselect.c (x_decline_selection_request)
22273 (x_reply_selection_request): Avoid type-punned deref of X events.
22275 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22277 Fix some uses of `int' instead of EMACS_INT.
22278 * search.c (string_match_1, fast_string_match)
22279 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22280 (scan_buffer, find_next_newline_no_quit)
22281 (find_before_next_newline, search_command, Freplace_match)
22282 (Fmatch_data): Make some `int' variables be EMACS_INT.
22284 * xdisp.c (display_count_lines): 3rd argument and return value now
22285 EMACS_INT. All callers changed.
22286 (pint2hrstr): Last argument is now EMACS_INT.
22288 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22289 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22290 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22291 (decode_coding_utf_16, decode_coding_emacs_mule)
22292 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22293 (decode_coding_ccl, decode_coding_charset)
22294 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22295 (decode_coding_iso_2022, decode_coding_emacs_mule)
22296 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22297 <char_offset, last_offset>: Declare EMACS_INT.
22298 (encode_coding_utf_8, encode_coding_utf_16)
22299 (encode_coding_emacs_mule, encode_invocation_designation)
22300 (encode_designation_at_bol, encode_coding_iso_2022)
22301 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22302 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22304 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22305 (encode_invocation_designation): Last argument P_NCHARS is now
22307 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22308 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22310 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22313 * ccl.c (Fccl_execute_on_string): Declare some variables
22316 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22318 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22320 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22322 * process.c (Fformat_network_address): Doc fix.
22324 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22326 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22328 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22330 * keyboard.c (read_char): Call Lisp function help-form-show,
22331 instead of using internal_with_output_to_temp_buffer.
22332 (Qhelp_form_show): New var.
22333 (syms_of_keyboard): Use DEFSYM macro.
22335 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22337 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22339 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22341 * process.c (Flist_processes): Remove to Lisp.
22342 (list_processes_1): Delete.

22346 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22348 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22350 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22352 Fix more problems found by GCC 4.6.0's static checks.
22354 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22356 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22358 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22360 * xdisp.c (vmessage): Mark as a printf-like function.
22362 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22364 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22366 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22367 printf-like functions.
22368 (tiff_load): Add casts to remove these marks before passing them
22369 to system-supplied API.
22371 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22373 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22374 This avoids several warnings with gcc -Wstrict-overflow.
22375 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22376 directly, rather than having caller test rule sign. This avoids
22377 some unnecessary tests.
22378 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22379 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22380 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22382 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22383 (xfont_open): Avoid unnecessary tests.
22385 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22387 * composite.h, composite.c (composition_gstring_put_cache):
22388 Use EMACS_INT, not int, for length.

22391 breaking out part of COMPOSITION_DECODE_RULE.
22392 (COMPOSITION_DECODE_RULE): Use it.
22393 * composite.c (get_composition_id): Remove unused local vars,
22394 by using the new macro.
22396 * textprop.c (set_text_properties_1): Change while to do-while,
22397 since the condition is always true at first.
22399 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22400 (interval_deletion_adjustment): Return unsigned value.
22403 * process.c (list_processes_1, create_pty, read_process_output):

22413 (update_syntax_table): Use unsigned instead of int.
22415 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22416 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22417 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22419 * print.c (print_error_message): Avoid int overflow.
22421 * font.c (font_list_entities): Redo for clarity,
22422 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22424 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22425 (font_score): Avoid potential overflow in diff calculation.
22427 * fns.c (substring_both): Remove var that is set but not used.
22428 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22430 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22432 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22433 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22434 can always succeed if overflow has undefined behavior.
22436 * search.c (boyer_moore, wordify): Remove vars set but not used.
22437 (wordify): Omit three unnecessary tests.
22439 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22440 All callers changed. This avoids the need for an unused var.
22442 * casefiddle.c (casify_region): Remove var that is set but not used.
22444 * dired.c (file_name_completion): Remove var that is set but not used.
22446 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22448 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22449 (Finsert_file_contents): Remove unnecessary code checking fd.
22451 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22452 Check for integer overflow on size calculations.
22454 * buffer.c (Fprevious_overlay_change): Remove var that is set
22457 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22458 Remove vars that are set but not used.
22459 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22460 (timer_check_2): Mark vars as initialized.
22462 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22464 * image.c (lookup_image): Remove var that is set but not used.
22465 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22467 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22468 that are set but not used.
22470 * xfns.c (make_invisible_cursor): Don't return garbage
22471 if XCreateBitmapFromData fails (Bug#8410).
22473 * xselect.c (x_get_local_selection, x_handle_property_notify):
22474 Remove vars that are set but not used.
22476 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

22486 (map_tty_color) [!defined MSDOS]: Likewise.
22488 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22490 * coding.c: Remove vars that are set but not used.
22491 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22492 All callers changed.

22494 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22495 (decode_coding_charset): Remove vars that are set but not used.
22497 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22498 that is set but not used.
22500 * print.c (print_object): Remove var that is set but not used.
22502 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22503 The gnulib version avoids calling malloc in the usual case,
22504 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22505 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22506 * filelock.c (current_lock_owner): Likewise.
22507 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

22510 (emacs_readlink): New function.
22511 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22512 ../lib/careadlinkat.h.
22514 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22516 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22517 first non-nil return value).

22531 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22532 and thereabouts. All callers changed.
22533 (get_per_char_metric): Remove parameter `f', unused since
22534 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22616 (try_scrolling): Use it when setting scroll_limit.
22617 Limit scrolling to 100 screen lines.
22618 (redisplay_window): Even when falling back on "recentering",
22619 position point in the window according to scroll-conservatively,
22620 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22622 (try_scrolling): When point is above the window, allow searching
22623 as far as scroll_max, or one screenful, to compute vertical
22624 distance from PT to the scroll margin position. This prevents
22625 try_scrolling from unnecessarily failing when
22626 scroll-conservatively is set to a value slightly larger than the
22627 window height. Clean up the case of PT below the margin at bottom
22628 of window: scroll_max can no longer be INT_MAX. When aggressive
22629 scrolling is in use, don't let point enter the opposite scroll
22630 margin as result of the scroll.
22631 (syms_of_xdisp) <scroll-conservatively>: Document the
22632 threshold of 100 lines for never-recentering scrolling.
22634 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22636 * dispextern.h (move_it_by_lines):
22637 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22638 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22639 (message_log_check_duplicate): Remove parameters `prev_bol' and
22640 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22641 (redisplay_internal): Remove parameter `preserve_echo_area',
22642 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22644 * indent.c (Fvertical_motion):
22645 * window.c (window_scroll_pixel_based, Frecenter):
22646 Don't pass `need_y_p' to `move_it_by_lines'.
22648 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22650 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22651 steal a few bits to be more compact.
22652 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22653 Remove unneeded casts.
22655 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22657 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22659 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22660 binding" message (bug#7967).
22662 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22664 Fix more problems found by GCC 4.6.0's static checks.
22666 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22667 Remove unused local var.
22669 * editfns.c (Fmessage_box): Remove unused local var.
22671 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22672 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22673 Omit unused local vars.
22674 * window.c (shrink_windows): Omit unused local var.
22675 * menu.c (digest_single_submenu): Omit unused local var.
22676 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22677 Omit unused local var.
22679 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22680 Don't assume string length fits in int.
22681 (keyremap_step, read_key_sequence): Use size_t for sizes.
22682 (read_key_sequence): Don't check last_real_key_start redundantly.
22684 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22685 instead of alloca (Bug#8344).
22687 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22688 (Fbacktrace_frame): Don't assume nframes fits in int.
22690 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22692 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22695 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22697 * cm.c (calccost): Turn while-do into do-while, for clarity.
22699 * keyboard.c (syms_of_keyboard): Use the same style as later
22700 in this function when indexing through an array. This also
22701 works around GCC bug 48267.
22703 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22705 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22707 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22708 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22710 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22711 This avoids undefined behavior on integer overflow, and is a bit
22712 more convenient anyway since it is compared to a size_t variable.
22714 Variadic C functions now count arguments with size_t, not int.
22715 This avoids an unnecessary limitation on 64-bit machines, which
22716 caused (substring ...) to crash on large vectors (Bug#8344).
22717 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22718 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

22722 * editfns.c (general_insert_function): Likewise.
22723 * eval.c (struct backtrace.nargs, interactive_p)
22724 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22725 (funcall_lambda, mark_backtrace): Likewise.
22726 * fns.c (concat): Likewise.
22727 * frame.c (x_set_frame_parameters): Likewise.
22728 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22729 0 if not found, not -1. All callers changed.
22731 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22732 (stack_copy_size): Now size_t, not int.
22733 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22735 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22737 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22738 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22739 All callers changed.
22741 * lisp.h (multibyte_char_to_unibyte):
22742 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22743 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22744 * character.h (CHAR_TO_BYTE8):
22745 * cmds.c (internal_self_insert):
22746 * editfns.c (general_insert_function):
22747 * keymap.c (push_key_description):
22748 * search.c (Freplace_match):
22749 * xdisp.c (message_dolog, set_message_1): All callers changed.
22751 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22753 * keyboard.c (safe_run_hook_funcall): New function.
22754 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22755 don't set the hook to nil, but remove the offending function instead.
22756 (Qcommand_hook_internal): Remove, unused.
22757 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22758 Vcommand_hook_internal.
22760 * eval.c (enum run_hooks_condition): Remove.
22761 (funcall_nil, funcall_not): New functions.
22762 (run_hook_with_args): Call each function through a `funcall' argument.
22763 Remove `cond' argument, now redundant.
22764 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22765 (Frun_hook_with_args_until_failure): Adjust accordingly.
22766 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22768 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22770 * dispextern.h (string_buffer_position): Remove declaration.
22772 * print.c (strout): Remove parameter `multibyte', unused since
22773 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22775 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22776 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22777 All callers changed.
22779 * w32.c (_wsa_errlist): Use braces for struct initializers.
22781 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22782 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22783 All callers changed.
22784 (string_buffer_position): Likewise. Also, make static (it's never
22785 used outside xdisp.c).
22786 (cursor_row_p): Remove parameter `w', unused since
22787 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22789 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22790 All callers changed.
22792 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22794 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

22805 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22807 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22809 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22811 2011-03-27 Glenn Morris <rgm@gnu.org>
22813 * syssignal.h: Replace RETSIGTYPE with void.
22814 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22815 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22816 Replace SIGTYPE with void everywhere.
22817 * s/usg5-4-common.h (SIGTYPE): Remove definition.

22820 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22822 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22823 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22825 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22827 * w32.c (read_unc_volume): Use parameter `henum', instead of
22828 global variable `wget_enum_handle'.
22830 * keymap.c (describe_vector): Remove parameters `indices' and
22831 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

22834 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22836 * keyboard.c (timer_check): Remove parameter `do_it_now',
22837 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22838 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22839 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22841 * keyboard.c (read_char):
22842 * w32menu.c (w32_menu_display_help):
22843 * xmenu.c (show_help_event, menu_help_callback):
22844 Adjust calls to `show_help_echo'.
22846 * gtkutil.c (xg_maybe_add_timer):
22847 * keyboard.c (readable_events):
22848 * process.c (wait_reading_process_output):
22849 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22851 * insdel.c (adjust_markers_gap_motion):
22852 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22853 (gap_left, gap_right): Don't call it.
22855 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

22902 Don't pass uninitialized region to CombineRgn.
22904 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22906 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

22926 2011-03-23 Julien Danjou <julien@danjou.info>
22928 * term.c (Fsuspend_tty, Fresume_tty):
22929 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22930 * window.c (temp_output_buffer_show):
22931 * insdel.c (signal_before_change):
22932 * frame.c (Fhandle_switch_frame):
22933 * fileio.c (Fdo_auto_save):
22934 * emacs.c (Fkill_emacs):
22935 * editfns.c (save_excursion_restore):
22936 * cmds.c (internal_self_insert):
22937 * callint.c (Fcall_interactively):
22938 * buffer.c (Fkill_all_local_variables):
22939 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22941 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22942 unconditionally since it does the check itself.
22944 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22946 Fix more problems found by GCC 4.5.2's static checks.
22948 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22949 the first time through the loop, since we know p0 < p1 then.
22950 This also avoids a gcc -Wstrict-overflow warning.
22952 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22953 leading to a memory leak, possible in functions like
22954 load_charset_map_from_file that can allocate an unbounded number
22955 of objects (Bug#8318).
22957 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22958 that could (at least in theory) be that large.
22960 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22961 This is less likely to overflow, and avoids undefined behavior if
22962 overflow does occur. All callers changed. Use strtoul to scan
22963 for the unsigned long integer.
22964 (pint2hrstr): Simplify and tune code slightly.
22965 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22967 * scroll.c (do_scrolling): Work around GCC bug 48228.
22968 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22970 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22971 This also avoids a warning with gcc -Wstrict-overflow.
22972 (validate_x_resource_name): Simplify count usage.
22973 This also avoids a warning with gcc -Wstrict-overflow.
22975 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22978 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22980 * process.c (Fmake_network_process): Use socklen_t, not int,
22981 where POSIX says socklen_t is required in portable programs.
22982 This fixes a porting bug on hosts like 64-bit HP-UX, where
22983 socklen_t is wider than int (Bug#8277).
22984 (Fmake_network_process, server_accept_connection):
22985 (wait_reading_process_output, read_process_output):
22988 * process.c: Rename or move locals to avoid shadowing.
22989 (list_processes_1, Fmake_network_process):
22990 (read_process_output_error_handler, exec_sentinel_error_handler):
22991 Rename or move locals.
22992 (Fmake_network_process): Define label "retry_connect" only if needed.
22993 (Fnetwork_interface_info): Fix pointer signedness.
22994 (process_send_signal): Add cast to avoid pointer signedness problem.
22995 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22996 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22998 Make tparam.h and terminfo.c consistent.
22999 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23000 Include tparam.h instead, since it declares them.
23001 * cm.h (PC): Remove extern decl; tparam.h now does this.
23002 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23003 * terminfo.c: Include tparam.h, to check interfaces.
23004 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23005 (tparam): Adjust signature to match interface in tparam.h;
23006 this removes some undefined behavior. Check that outstring and len
23007 are zero, which they always are with Emacs.
23008 * tparam.h (PC, BC, UP): New extern decls.
23010 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23011 (xftfont_open): Rename locals to avoid shadowing.
23013 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
23014 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
23015 (OTF_TAG_SYM): Omit macro if not needed.
23016 (ftfont_list): Remove unused local.
23017 (get_adstyle_property, ftfont_pattern_entity):
23018 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
23019 Rename locals to avoid shadowing.
23021 * xfont.c (xfont_list_family): Mark var as initialized.
23023 * xml.c (make_dom): Now static.
23025 * composite.c (composition_compute_stop_pos): Rename local to
23027 (composition_reseat_it): Remove unused locals.
23028 (find_automatic_composition, composition_adjust_point): Likewise.
23029 (composition_update_it): Mark var as initialized.
23030 (find_automatic_composition): Mark vars as initialized,
23031 with a FIXME (Bug#8290).
23033 character.h: Rename locals to avoid shadowing.
23034 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23035 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23036 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23037 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23038 to avoid shadowing.
23040 * textprop.c (property_change_between_p): Remove; unused.

23057 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23059 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23060 clobbering (Bug#8298).
23061 * sysdep.c (sys_subshell): Likewise.
23062 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23064 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23065 This should get cleaned up, so that child_setup has the
23066 same signature on all platforms.
23068 * callproc.c (call_process_cleanup): Now static.
23069 (relocate_fd): Rename locals to avoid shadowing.
23071 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

23200 some of which prompt warnings from gcc -Wbad-function-cast.
23201 (Fformat_time_string, Fencode_time, Finsert_char):

23230 (Fmemory_limit): Cast sbrk's returned value to char *.
23232 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

23237 Use functions, not macros, for up- and down-casing (Bug#8254).
23238 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23239 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23240 to use the following functions instead of these macros.
23241 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23242 EMACS_INT, since callers assume the returned value fits in int.
23243 (upcase1): Likewise, for UPCASE_TABLE.
23244 (uppercasep, lowercasep, upcase): New static inline functions.
23245 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23255 (regex_compile, re_match_2_internal): Mark locals as initialized.
23256 (RETALLOC_IF): Define only if needed.
23257 (WORDCHAR_P): Likewise. This one is never needed, but is used
23258 only in a comment talking about a compiler bug, so put inside
23259 the #if 0 of that comment.
23260 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23261 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23287 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23288 New macros, so that the caller can use some names other than
23289 gcpro1, gcpro2, etc.
23290 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23292 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23293 argument, for consistency with GCPRO2_VAR, etc: it is now the
23294 prefix of the variable, not the variable itself. All uses
23296 * dired.c (directory_files_internal, file_name_completion):
23297 Rename locals to avoid shadowing.
23299 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23300 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23301 dired.c's scmp function, had undefined behavior.
23302 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23303 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23304 * buffer.h: ... to here, because these macros use current_buffer,
23305 and the new implementation with inline functions needs to have
23306 current_buffer in scope now, rather than later when the macros
23308 (downcase, upcase1): New static inline functions.
23309 (DOWNCASE, UPCASE1): Reimplement using these functions.
23310 This avoids undefined behavior in expressions like
23311 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23312 from race conditions in accessing the global variables
23313 case_temp1 and case_temp2.
23314 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23315 * lisp.h (case_temp1, case_temp2): Remove their decls.
23316 * character.h (ASCII_CHAR_P): Move from here ...
23317 * lisp.h: ... to here, so that the inline functions mentioned
23318 above can use them.
23320 * dired.c (directory_files_internal_unwind): Now static.
23322 * fileio.c (file_name_as_directory, directory_file_name):

23325 (file_name_as_directory): Use const pointers when appropriate.
23326 (Fexpand_file_name): Likewise. In particular, newdir might
23327 point at constant storage, so make it a const pointer.
23328 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23329 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23331 (Fset_file_times, Finsert_file_contents, auto_save_error):

23336 to avoid shadowing.
23338 * marker.c (bytepos_to_charpos): Remove; unused.
23340 * lisp.h (verify_bytepos, count_markers): New decls,
23341 so that gcc does not warn that these functions aren't declared.
23343 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23344 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23345 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23346 (copy_text): Remove unused local var.
23348 * filelock.c (within_one_second): Now static.
23349 (lock_file_1): Rename local to avoid shadowing.
23351 * buffer.c (fix_overlays_before): Mark locals as initialized.
23352 (fix_start_end_in_overlays): Likewise. This function should be
23353 simplified by using pointers-to-pointers, but that's a different
23355 (switch_to_buffer_1): Now static.
23356 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23357 (report_overlay_modification): Rename locals to avoid shadowing.
23359 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23360 Fix pointer signedness issue.
23361 (sys_subshell): Mark local as volatile if checking for lint,
23362 to suppress a gcc -Wclobbered warning that does not seem to be right.
23363 (MAXPATHLEN): Define only if needed.
23365 * process.c (serial_open, serial_configure): Move decls from here ...
23366 * systty.h: ... to here, so that they can be checked.
23368 * fns.c (get_random, seed_random): Move extern decls from here ...
23369 * lisp.h: ... to here, so that they can be checked.
23371 * sysdep.c (reset_io): Now static.
23372 (wait_for_termination_signal): Remove; unused.
23374 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23377 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23378 (DENSE_TABLE_SIZE): Remove; unused.
23379 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23380 (describe_map_tree):
23381 Rename locals to avoid shadowing.
23383 * keyboard.c: Declare functions static if they are not used elsewhere.
