3 The following changes are to fix the setting of
4 buffer-file-coding-system on, for instance, C-x RET c unix RET
5 _FILE_OF_DOS_EOL_TYPE_ RET.
7 * coding.h (struct coding_system): New member detected_utf8_chars.
9 * coding.c (detect_coding_utf_8): Count characters and check EOL
10 format. Include CATEGORY_MASK_UTF_8_AUTO in detect_info->found if
12 (setup_coding_system): Do not initialize coding->head_ascii.
13 (check_ascii): Do not set coding->eol_seen but update it. Do not
14 call adjust_coding_eol_type here.
15 (detect_coding): Fix detection of BOM for utf-8 and utf-16. If
16 the eol-type of CODING is already specified, adjust the eol type
17 of the found coding-system.
18 (decode_coding_gap): Cancel previous change. Utilize the
19 character numbers counted by detect_coding_utf_8. Fix detection
22 2013-05-08 Paul Eggert <eggert@cs.ucla.edu>
24 * xterm.h (GTK_PREREQ): New macro.
25 All simple uses of GTK_MAJOR_VERSION and GTK_MINOR_VERSION changed
26 to use this macro instead, for consistency and clarity.
28 2013-05-08 Eli Zaretskii <eliz@gnu.org>
30 * xdisp.c (row_for_charpos_p): New function, with code of
31 cursor_row_p, but accepts an additional argument CHARPOS instead
32 of using a hardcoded PT.
33 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
34 (row_containing_pos): Call row_for_charpos_p instead of partially
35 doing the same. Fixes cursor positioning under longlines-mode
36 when longlines-show-effect includes more than one newline, when
37 moving the cursor vertically up.
39 2013-05-08 Juanma Barranquero <lekktu@gmail.com>
41 * makefile.w32-in (ACL_H): New macro.
42 ($(BLD)/fileio.$(O)): Update dependencies.

51 Use HAVE_ACL_SET_FILE rather than HAVE_POSIX_ACL.
52 (ACL_NOT_WELL_SUPPORTED): Remove. All uses replaced by
54 (Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling
57 * unexelf.c: Don't assume ElfW (Half) fits in int.
58 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
59 when dealing with ElfW (Half) values, since they can exceed 2**31
60 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
61 (entry_address): Omit unused NUM arg. All uses changed.
63 2013-05-07 Juri Linkov <juri@jurta.org>
65 * callint.c (Fcall_interactively): Set `visargs[i]' for code 'n'
66 to the string converted from number with `Fnumber_to_string'.
69 2013-05-07 Paul Eggert <eggert@cs.ucla.edu>
71 * xfns.c (x_get_net_workarea): Define only if !GTK || GTK<3.4.
72 This fixes a problem introduced by my previous change.
74 2013-05-07 Glenn Morris <rgm@gnu.org>
76 * lread.c (readchar): Don't read from a dead buffer. (Bug#14280)
78 2013-05-07 Jan Djärv <jan.h.d@swipnet.se>
80 * xfns.c: Move misplaced ifndef USE_GTK from previous checkin.
82 2013-05-07 Paul Eggert <eggert@cs.ucla.edu>
84 Static checking by GCC 4.8.0.
85 * xfns.c (x_get_net_workarea, struct MonitorInfo, free_monitors)

87 (x_get_monitor_attributes_fallback)
88 (x_get_monitor_attributes_xinerama)
89 (x_get_monitor_attributes_xrandr, x_get_monitor_attributes):
90 Define only if USE_GTK.
91 (free_monitors): Define only if HAVE_XINERAMA || HAVE_XRANDR.
92 (x_get_monitor_attributes_fallback): Omit unused locals.
93 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
94 Use double, not float, to avoid mixed-mode floating point arithmetic.

97 Jan Djärv <jan.h.d@swipnet.se>
99 * Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
100 (XINERAMA_CFLAGS): New macros.
101 (ALL_CFLAGS, LIBES): Use them.

105 (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.
106 (syms_of_xfns): DEFSYM them.
107 (struct MonitorInfo): New struct.
108 (x_get_net_workarea, free_monitors, x_get_monitor_for_frame)

110 (x_get_monitor_attributes_xrandr, x_get_monitor_attributes)
111 (x_get_monitor_attributes_xinerama): New functions.
112 (Fx_display_monitor_attributes_list): New primitive.
113 (syms_of_xfns): Defsubr it.
115 * xterm.h (x_display_info): Add Xatom_net_workarea and
116 Xatom_net_current_desktop.
118 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
119 and dpyinfo->Xatom_net_current_desktop.
121 2013-05-06 Eli Zaretskii <eliz@gnu.org>
123 * xdisp.c (pos_visible_p): Use the special code for finding the
124 beginning of a display property or overlay for any "replacing"
125 display property, not just for display strings. This solves
126 incorrect reporting of position by posn-at-point. (Bug#14241)
128 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
130 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
131 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
132 Verify that ElfW (Half) fits in int.
133 (fatal): Use same signature as lisp.h.
134 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
135 configure and build with -DUNEXELF_DEBUG without worrying about
136 other modules that use DEBUG.
137 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
138 possibly-wide integers now uses it instead of plain fprintf.
139 (entry_address): New function, which avoids problems with 32-bit
140 overflow on 64-bit hosts.
141 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
142 (round_up): Don't assume the remainder fits in int.
143 (find_section): Use bool for boolean. Simplify debug code.
144 (unexec): Don't assume file sizes fit in int or size_t.
145 Omit unnecessary trailing newline in 'fatal' format.
146 Use strerror rather than outputting decimal error number.
147 Remove unused code when emacs is not defined;
148 this file relies on Emacs now.
149 Don't assume e_phnum and e_shnum are positive.
151 * regex.c: Fix problems when DEBUG is defined.
152 (extract_number, extract_number_and_incr): Define regardless of
153 whether DEBUG is defined; that's simpler and makes the code less
154 likely to go stale in the normal case when DEBUG is not defined.
155 Return int rather than taking an int * arg. All callers changed.
156 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
157 Remove, replacing with ...
158 (DEBUG_PRINT): New macro. All callers changed.
159 (DEBUG_COMPILES_ARGUMENTS): New macro.
160 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
161 (print_compiled_pattern, print_double_string) [DEBUG]:
162 Use prototype rather than old-style definition.

164 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
165 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
166 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
167 Don't assume ptrdiff_t, size_t, and long are the same width as int.
168 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
169 This matters only when DEBUG is defined.
171 2013-05-05 Eli Zaretskii <eliz@gnu.org>
173 * xdisp.c (set_iterator_to_next): Set the
174 ignore_overlay_strings_at_pos_p flag only if we are _really_
175 iterating over an overlay string, as indicated by the
176 current.overlay_string_index member. (Bug#14306)
178 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
180 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
181 to where it is used, to avoid autorelease issues (Bug#14050).
183 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
185 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
186 * fileio.c (syms_of_fileio): Implement this.
187 * filelock.c (create_lock_file): If symbolic links don't work, so
188 we use a regular file as a lock file, do not fsync the lock file;
191 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
193 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

201 w->contents is a buffer before computing everything else.
202 Use parentheses to disambiguate last part of the condition.
204 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
205 assertion violations. (Bug#14062)
207 2013-05-01 David Reitter <david.reitter@gmail.com>
209 * nsfns.m (ns_tooltip): Initialize.
211 2013-04-28 Eli Zaretskii <eliz@gnu.org>
213 * coding.c (decode_coding_gap): Don't remove the character before
214 a newline unless it's a CR character. (Bug#14287)
216 2013-04-28 Dan Nicolaescu <dann@gnu.org>
218 * dispextern.h (struct face): Move enum face_underline_type

228 2013-04-27 Juri Linkov <juri@jurta.org>
230 * callint.c (Fcall_interactively): Call `Qread_number' for
231 interactive code letter `n' instead of using duplicate code.
234 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
236 * systime.h (make_timeval): Declare as 'const'.
238 2013-04-27 Kenichi Handa <handa@gnu.org>
240 * font.c (font_open_entity): Always open a font of manageable
243 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
245 Port better to AIX (Bug#14258).
246 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
249 2013-04-24 Kenichi Handa <handa@gnu.org>
251 * coding.c (decode_coding_iso_2022): When an invalid escape
252 sequence is encountered, reset the invocation and designation
253 status to the safest one.
255 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
257 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
258 Without this fix, "make distclean" leaves stamp-h1 behind.
260 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
262 * w32fns.c (w32_fullscreen_rect): New function to compute the
263 window rectangle for the given fullscreen mode.
264 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
265 longer tunes the window size. This keeps the window's edges flush
266 with the screen and allows the taskbar to hide itself in fullboth.
268 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
269 window decorations and uses the entire screen.
271 * w32term.h (w32_fullscreen_rect) Add prototype.
272 (struct w32_output): Replace normal_width, normal_height,
273 normal_top, and normal_left members with a single normal_placement
275 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):

281 * minibuf.c (Ftest_completion): Silence compiler warning.
283 2013-04-15 Eli Zaretskii <eliz@gnu.org>
285 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
288 * frame.h (WINDOW_FRAME): Protect macro and its argument with
291 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
292 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
293 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
294 parentheses where appropriate.
296 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
298 * keyboard.c (timer_start_idle): Remove no-longer-used local.
300 2013-04-14 Eli Zaretskii <eliz@gnu.org>
302 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
303 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
304 Mention in the doc string that setting these variables takes
305 effect only after a call to set-window-buffer. (Bug#14200)
307 2013-04-13 Eli Zaretskii <eliz@gnu.org>
309 * indent.c (Fvertical_motion): Don't consider display strings on
310 overlay strings as display strings on the buffer position we
311 started from. This prevents vertical cursor motion from jumping
312 more than one line when there's an overlay string with a display
313 property at end of line.
314 Reported by Karl Chen <Karl.Chen@quarl.org> in
315 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
317 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
319 * window.c (select_window): `record_buffer' even if window is
320 already selected (bug#14191).
322 2013-04-11 Eli Zaretskii <eliz@gnu.org>
324 * window.c (Fwindow_end): Test more flags, including the buffer's
325 last_overlay_modified flag, to determine whether the window's
326 display is really up-to-date. Prevents the function from
327 returning a stale value. (Bug#14170)
328 (Fwindow_line_height): Fix the test for up-to-date-ness of the
331 2013-04-10 Eli Zaretskii <eliz@gnu.org>
333 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
334 garbaged only if it is not already the top frame on its TTY.
335 This prevents flickering due to constant redrawing of TTY frames when
336 there are GUI frames open in the same session. (Bug#13864)
338 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
340 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
341 of marking the idle timers directly.
343 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
345 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
348 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>
350 * window.c (select_window): Don't record_buffer while the invariant is
351 temporarily broken (bug#14161).
353 * fns.c (Fdelq): Don't assume !NILP => CONSP.
355 2013-04-07 Eli Zaretskii <eliz@gnu.org>

365 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
367 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
370 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
372 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
373 This bug was introduced by my 2013-02-25 change that simplified
374 data_start configuration. Without this change, on GNU/Linux
375 an Emacs configured with --enable-profiling fails immediately
376 due to a profiler signal.
377 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
378 with these flags. On platforms where special flags are needed
379 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
380 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
381 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
383 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

391 * frame.h (decode_window_system_frame, window_system_available):
392 ...here, add new prototypes.

453 2013-04-02 Paul Eggert <eggert@cs.ucla.edu>
455 Prefer < to > in range checks such as 0 <= i && i < N.
456 This makes it easier to visualize quantities on a number line.
457 This patch doesn't apply to all such range checks,
458 only to the range checks affected by the 2013-03-24 change.
459 This patch reverts most of the 2013-03-24 change.

544 * window.h (struct window): Replace hchild, vchild and buffer slots
545 with the only contents slot. This is possible because each valid

548 a lof of operations to traverse and/or change window hierarchies may
549 be simplified. New member horizontal is used to distinguish between

587 (expose_window_tree): Likewise.
588 Use contents slot, not buffer, where appropriate.
589 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
590 to avoid deleted windows. Use contents slot instead of buffer.
591 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
592 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:
593 * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c:

616 selected_window always displays the buffer.
617 * buffer.c (Fbuffer_swap_text): Adjust window start markers.

963 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
966 2013-03-13 Daniel Colascione <dancol@dancol.org>
968 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
969 too so that these builds can use Cygwin's file conversion
970 functions. (We've been building and linking cygw32.o all along
971 and just not using it.)
973 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
975 File synchronization fixes (Bug#13944).
976 * Makefile.in (LIB_FDATASYNC): New macro.
978 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
979 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
980 Don't worry about HAVE_FSYNC, since a substitute fsync is
981 available if the system lacks one.
982 (Fwrite_regin): Retry fsync if interrupted.
984 2013-03-13 Eli Zaretskii <eliz@gnu.org>
986 * w32term.c (w32_read_socket): If the Emacs frame is being
987 activated, call w32fullscreen_hook, to make sure the new frame
988 dimensions are in effect. (Bug#13937)
990 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
992 * xdisp.c (init_iterator): Simplify because both character and byte
993 positions are either specified or -1. Add eassert. Adjust comment.
994 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
995 character and byte positions can be obtained from marker.
997 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
999 Static checking by Sun C 5.12.

1012 a function pointer type; the C Standard requires this.
1014 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1015 Include <sys/param.h> unconditionally, as that works elsewhere and
1016 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1017 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1020 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

1049 common file dialog code.
1051 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1052 can just use du like other systems.
1054 * coding.c (from_unicode_buffer): Declare.
1055 * coding.c (from_unicode_buffer): Implement.
1057 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1101 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
1103 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1104 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1105 from Elisp via unread-command-events.
1107 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1108 functions to mean "no change".
1110 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1112 region-cache.c, scroll.c, search.c: Use bool for booleans.
1113 * lisp.h (compile_pattern):

1118 (search_regs_saved, Fregexp_quote):
1119 Use bool for boolean.
1120 * region-cache.c (region_cache_forward, region_cache_backward):
1121 Fix comments to match code: these functions return int, not boolean.
1123 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1125 * search.c (find_newline): Accept start and end byte positions
1126 as arguments and allow -1 if not known.
1127 (find_newline_no_quit): Likewise for start position.
1128 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1129 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1130 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1131 * editfns.c (Fconstrain_to_field): Break long line.
1132 Adjust call to find_newline.
1133 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1137 (get_visually_first_element, move_it_vertically_backward): Likewise.
1138 Obtain byte position from the display iterator, where appropriate.
1140 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1142 print.c, process.c: Use bool for booleans.
1143 * lisp.h (wait_reading_process_output):

1158 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1160 * bidi.c (bidi_fetch_char): Swap first and second arguments
1161 to match other functions accepting character and byte positions.
1163 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1164 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1165 when you need just to move to the previous buffer position.
1166 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1168 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1184 byte position and adjust call to vmotion.
1185 (window_scroll_line_based): Likewise with call to compute_motion.
1187 (Frecenter): Adjust calls to vmotion.
1189 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1191 * lisp.h (list2i, list3i): New functions.

1205 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1207 * search.c (find_newline_no_quit): Rename from find_next_newline.
1210 * lisp.h (find_newline_no_quit): Rename prototype.

1226 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1227 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1228 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1229 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)

1241 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1243 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1244 * sysdep.c (list_system_processes)
1245 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1246 Make it a stub in this case; otherwise the build might fail,
1247 and this code hasn't been tested on such hosts anyway.
1248 Problem reported by Nelson H. F. Beebe in
1249 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1250 and analyzed by Jérémie Courrèges-Anglas in
1251 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1253 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1255 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1256 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1257 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1258 * bidi.c (bidi_find_paragraph_start): Likewise.
1259 * indent.c (vmotion): Likewise.
1261 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1263 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1264 * filelock.c: Include <c-ctype.h>.
1265 (MAX_LFINFO): New top-level constant.
1266 (lock_info_type): Remove members pid, boot_time. Add members at,
1267 dot, colon. Change user member to be the entire buffer, not a
1268 pointer. This allows us to handle the case where a foreign
1269 pid or boot time exceeds the local range. All uses changed.
1270 (LINKS_MIGHT_NOT_WORK): New constant.
1271 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1272 (defined_WINDOWSNT): Remove.
1273 (MAKE_LOCK_NAME, file_in_lock_file_name):
1274 Always use .#FILE (not .#-FILE) for the file lock,
1275 even if it is a regular file.
1276 (rename_lock_file): New function.
1277 (create_lock_file): Use it.
1278 (create_lock_file, read_lock_data):
1279 Prefer a symbolic link for the lock file, falling back on a
1280 regular file if symlinks don't work. Do not try to create
1281 symlinks on MS-Windows, due to security hassles. Stick with
1282 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1283 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1284 host may be using a Windowsish file system, and cannot use
1285 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1286 doesn't work. Don't fail merely because of a symlink-contents
1287 length limit in the current file system; fall back on regular
1288 files. Increase the symlink contents length limit to 8 KiB, this
1289 should be big enough for any real use and doesn't crunch the
1291 (create_lock_file, lock_file_1, read_lock_data):
1292 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1293 (lock_file_1): Return error number, not bool. All callers changed.
1294 (ELOOP): New macro, if not already defined.
1295 (read_lock_data): Return size of lock file contents, not Lisp object.
1296 All callers changed. Handle a race condition if some other process
1297 replaces a regular-file lock with a symlink lock or vice versa,
1298 while we're trying to read the lock.
1299 (current_lock_owner): Parse contents more carefully, to help avoid
1300 confusing a regular-file lock with some other application's use
1301 of the file. Check for lock file contents being too long, or
1302 not parsing correctly.
1303 (current_lock_owner, lock_file):
1304 Allow foreign pid and boot times that exceed the local range.
1305 (current_lock_owner, lock_if_free, lock_file):
1306 Simplify allocation of lock file contents.
1307 * w32.c (sys_rename_replace): New function, containing most of
1308 the contents of the old sys_rename.
1309 (sys_rename): Use it.
1310 (fchmod): New dummy function.
1311 * w32.h (sys_rename_replace, fchmod): New decls.
1313 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1315 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1316 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1317 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1318 <dmantipov@yandex.ru>.
1320 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1322 * composite.c (get_composition_id, fill_gstring_header):
1323 Use make_uninit_vector where appropriate.
1324 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1325 * xselect.c (clean_local_selection_data): Likewise.
1327 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1329 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1330 * image.c (imagemagick_load_image): Calculate height and width
1331 after flattening the image, not before.
1333 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1335 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1336 * ftfont.c (ftfont_shape_by_flt): Likewise.
1337 * w32uniscribe.c (uniscribe_shape): Likewise.
1339 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1341 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1342 The old approach, which fell back on DIR/.#FILE.0 through
1343 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1344 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1345 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1346 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1347 because the locking mechanism was never reliable in that case).
1348 This patch fixes this and other bugs discovered by a code
1349 inspection that was prompted by
1350 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1351 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1352 to avoid interoperability problems between the MS-Windows and
1353 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1354 instances of Emacs now ignore each others' locks.
1355 * filelock.c (defined_WINDOWSNT): New constant.
1356 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1357 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1358 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1359 regular files on MS-Windows hosts.
1360 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1361 Use SAFE_ALLOCA to avoid problems with long file names.
1362 (MAX_LFINFO): Now a local constant, not a global macro.
1363 (IS_LOCK_FILE): Remove.
1364 (lock_file_1): Don't inspect errno if symlink call succeeds;
1365 that's not portable.
1366 (lock_file): Document that this function can return if lock
1368 (lock_file): Don't access freed storage.
1370 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1372 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1374 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1376 * textprop.c: Use bool for booleans.
1377 (validate_interval_range, Fadd_text_properties)
1378 (Fremove_text_properties): Prefer bool to int when either works.
1380 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1382 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1383 If the interval tree changes as a side effect of calling
1384 modify_region, re-do processing starting from the call to
1385 validate_interval_range. (Bug#13743)
1387 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1389 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1392 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1394 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1395 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1396 access to the lock file until it is written and closed.
1399 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1401 * callint.c (Qcall_interactively):
1402 * macros.c (Qexecute_kbd_macro):
1405 2013-02-26 Bastien Guerry <bzg@gnu.org>
1407 * window.c (Frecenter): Tiny docstring enhancement.
1409 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1411 Minor textprop integer cleanup.
1412 * intervals.h, textprop.c (add_text_properties_from_list):
1413 Return void, not int, since nobody uses the return value.
1414 * textprop.c (validate_plist, add_properties, remove_properties)
1415 (Fadd_text_properties):
1416 Don't assume list length fits in int.

1428 Implement CLASH_DETECTION for MS-Windows.
1430 * filelock.c [WINDOWSNT]: Include w32.h.
1431 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1432 function of that name. Up-case the macro arguments.
1433 (IS_LOCK_FILE): New macro.
1434 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1435 (create_lock_file): New function, with body extracted from

1438 the lock information as its contents.
1439 (read_lock_data): New function, on Posix platforms just calls
1441 [WINDOWSNT]: Read the lock info from the file.
1442 (current_lock_owner): Call read_lock_data instead of calling
1443 emacs_readlinkat directly.
1444 (lock_file) [WINDOWSNT]: Run the file name through
1447 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1448 just check if the process by that PID exists.
1450 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1451 also present, as doing so will fail to error out if the file
1454 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1456 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1457 (Fremove_list_of_text_properties): Skip all of the intervals in
1458 the region between START and END that already have resp. don't
1459 have the requested properties, not just the first one.
1460 Add assertions that the loop afterwards always modifies the
1461 properties. (Bug#13743)
1463 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1465 * callint.c (Fcall_interactively): Use the right lexical environment

1474 (START_FILES): Remove. All uses removed.
1475 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1476 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1477 (buildobj.h): Use it.
1478 ($(ALLOBJS)): Depend on globals.h.
1479 (temacs$(EXEEXT)): Use $(ALLOBJS).
1480 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1481 * deps.mk (vm-limit.o):
1482 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1483 Do not depend on mem-limits.h.
1484 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1485 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
1486 [__GNUC__ && !ORDINARY_LINK]: Remove.

1489 * unexcoff.c (etext): New decl.
1490 (make_hdr): Use DATA_START instead of start_of_data.
1491 * vm-limit.c: Move most of mem-limits.h's contents here.
1492 (data_start): New decl. It's OK if this is approximate,
1493 so simplify-away some unnecessary exactness.
1494 (POINTER): Remove; all uses removed.
1495 (data_space_start): Now char *, to avoid casts.
1496 (exceeds_lisp_ptr): New function, replacing the old
1497 EXCEEDS_LISP_PTR macro. All uses changed.

1516 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1518 Assume C89 or better.
1519 * ralloc.c (SIZE, POINTER, NIL):
1520 * vm-limit.c (POINTER):
1521 Remove, replacing all uses with C89 equivalents. These old
1522 symbols were present only for porting to pre-C89 platforms.
1524 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1526 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1527 This avoids warning messages reported as part of Bug#13546.
1529 2013-02-21 Ken Brown <kbrown@cornell.edu>
1531 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1533 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1535 * sheap.c (report_sheap_usage): Prefer message1_nolog.
1537 * keyboard.c (Qcommand_execute): New var.
1538 (command_loop_1, read_char): Use it.
1539 (Fcommand_execute): Remove, replace by an Elisp implementation.

1542 2013-02-19 Daniel Colascione <dancol@dancol.org>
1544 * sheap.c (report_sheap_usage): Use message, not message1, so
1545 that we don't try to create a buffer while we're in the middle
1546 of dumping Emacs. Explain why.
1548 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1550 * search.c (find_newline): Return byte position in bytepos.

1561 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1563 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1565 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1566 resources were not orderly released.
1568 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1570 * xdisp.c (x_draw_vertical_border): For a window that is neither
1571 the leftmost nor the rightmost, redraw both the left and the right
1572 vertical borders. (Bug#13723)
1574 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

1592 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1594 * w32.c (sys_chown): Remove unused function.
1596 * w32term.c <input_signal_count>: Declare 'volatile'
1597 unconditionally. (Bug#9066)
1599 * w32.c (set_errno): Reset h_errno and don't set it to any other
1600 value. Set errno instead.
1601 (check_errno): Reset h_errno.
1602 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1603 (sys_gethostname, sys_getservbyname, sys_getpeername)
1604 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1605 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
1607 (sys_gethostbyname): Set h_errno only errors detected.
1609 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1611 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1613 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1615 * keyboard.c (read_char): Fix calculation of auto-save time out
1616 when auto-save-timeout is less than 4. (Bug#13720)
1618 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1619 time. Improve diagnostics in DebPrint. (Bug#13546)

1627 value that is out of bounds.
1628 (sys_accept): If fd is negative, do not set up the child_process
1629 structure for reading.

1640 (get_overlay_arrow_glyph_row, display_mode_element):
1641 (decode_mode_spec_coding, message3):
1642 * xfaces.c (face_at_string_position): Use bool for booleans.
1645 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1647 Fix AIX port (Bug#13650).
1648 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1649 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1650 was #undeffed earlier, so it cannot be used as a macro here.
1651 Use the constant and not the macro.
1653 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1655 * w32proc.c (new_child): If no vacant slots are found in
1656 child_procs[], make another pass looking for slots whose process
1657 has exited or died. (Bug#13546)
1659 * w32.c (sys_pipe): When failing due to file descriptors above
1660 MAXDESC, set errno to EMFILE.
1661 (_sys_read_ahead): Update cp->status when failing to read serial
1662 communications input, so that the status doesn't stay at
1663 STATUS_READ_IN_PROGRESS. (Bug#13546)
1665 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1667 * gtkutil.c (tb_size_cb): New function.
1668 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1670 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1672 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1675 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1677 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1679 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1685 Break long line. Remove useless prototype and format comment.
1687 2013-02-13 Glenn Morris <rgm@gnu.org>
1689 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1691 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1693 Improve AIX port some more (Bug#13650).
1694 With this, it should be as good as it was in 23.3, though it's
1695 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1696 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1697 * unexaix.c (start_of_text): Remove.
1698 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1699 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1700 (orig_load_scnptr, orig_data_scnptr):
1701 Now off_t, not long, since they are file offsets.
1702 (make_hdr): Use _data, not start_of_data ().
1703 This is the key part of the fix.
1704 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1705 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1707 * pre-crt0.c (data_start): Initialize to 1.
1708 This ports to compilers that optimize the external declaration
1709 'int x = 0;' as if it were 'int x;' to shrink the executable.
1711 Improve AIX port (Bug#13650).
1712 This doesn't fix the bug, but it makes progress: Emacs builds now.
1713 * unexaix.c: Include inttypes.h, stdarg.h.
1714 (report_error, report_error_1): Mark as _Noreturn.
1715 (report_error): Don't report the wrong errno.
1716 (report_error_1): Now varargs. All callers changed.
1717 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1718 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1719 (write_ptr): Use %p to print address rather than %lx and a cast
1720 to unsigned long. Grow buffer a bit, to be safer.
1722 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1724 * bidi.c (bidi_resolve_neutral): After finding the next
1725 non-neutral character, accept NEUTRAL_ON type as well, because
1726 directional control characters, such as LRE and RLE, have their
1727 type converted to that by bidi_resolve_weak. This avoids aborts
1728 when LRE/RLE follows a run of neutrals.
1729 (bidi_move_to_visually_next): Assert that return value of
1730 bidi_peek_at_next_level is non-negative. Negative values will
1733 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1735 Minor getenv-related fixes.
1736 * callproc.c (Fcall_process_region) [!DOS_NT]:
1737 Avoid unnecessary duplicate call to getenv.
1738 * callproc.c (init_callproc):
1739 * dispnew.c (init_display):
1740 * sysdep.c (sys_subshell):
1741 Omit unnecessary cast of getenv or egetenv.
1743 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1745 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1746 Update dependencies.
1748 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1750 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1752 (display_line): Set w->region_showing to the value of
1753 it->region_beg_charpos, not to -1. This fixes redisplay
1754 optimization when cursor is moved up after M->. (Bug#13623)
1756 (try_scrolling): Scroll text up more if point is too close to ZV
1757 and inside the scroll margin. This makes sure point is moved
1758 outside the scroll margin in these cases.
1760 * window.h (struct window): region_showing can no longer be
1763 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1765 Tune by using memchr and memrchr.
1766 * doc.c (Fsnarf_documentation):
1767 * fileio.c (Fsubstitute_in_file_name):
1768 * search.c (find_newline, scan_newline):
1769 * xdisp.c (pos_visible_p, display_count_lines):
1770 Use memchr and memrchr rather than scanning byte-by-byte.
1771 * search.c (find_newline): Rename from scan_buffer.
1772 Omit first arg TARGET, as it's always '\n'. All callers changed.
1774 Clean up read_key_sequence a tiny bit more.
1775 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1776 (read_key_sequence): Remove unused locals.
1778 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1780 Clean up read_key_sequence a bit; reread active keymaps after first event.
1781 * keyboard.c (read_char, read_char_x_menu_prompt)
1782 (read_char_minibuf_menu_prompt):
1783 Replace nmaps+maps with a single `map' arg.
1784 (follow_key): Operate on a single map.
1785 (active_maps): New function.
1786 (test_undefined): Also return true for nil bindings.
1787 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1788 a single (composed) keymap. Remember `first_event' to choose the right
1789 set of active keymaps. Recompute the set of keymaps after receiving
1790 the first event. Remove GOBBLE_FIRST_EVENT.
1791 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1792 * keyboard.h (read_char): Update declaration.
1793 * lread.c (read_filtered_event): Adjust call to read_char.
1795 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1797 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1798 Don't use the limitation on backwards movement when lines are truncated
1799 in the window. (Bug#13675)
1801 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1803 * marker.c (set_marker_internal): If desired position is passed
1804 as a marker, avoid call to buf_charpos_to_bytepos.
1805 * window.c (Fset_window_point): Omit redundant type checking.
1806 (Fset_window_start): Likewise. Format comment.
1807 (window_scroll_pixel_based): Use set_marker_restricted_both
1808 with character and byte positions obtained from an iterator.
1809 (Fset_window_configuration): Use set_marker_restricted_both.
1810 * xdisp.c (message_dolog): Likewise.
1812 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1814 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1815 When text lines are longer than window's screen lines, don't move back
1816 too far. This speeds up some redisplay operations. (Bug#13675)
1818 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1820 * syntax.c (scan_sexps_forward): Fix byte position calculation
1821 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1823 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1825 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1826 that was not needed.
1828 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1830 Minor hashing refactoring.
1831 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1832 (sxhash_float): Return EMACS_UINT, for consistency with the other
1834 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1835 non-static inline function and therefore can't use static vars.
1836 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1837 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1838 with the other hash functions.
1840 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1842 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1843 XXXXXX part of the temporary file pattern is not downcased even
1844 when w32-downcase-file-names is non-nil. (Bug#13661)
1846 * xdisp.c (decode_mode_spec): Remove handling of %t.
1848 * msdos.c (careadlinkatcwd): Remove.

1856 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1858 * search.c (scan_buffer): Calculate end byte position just once.

1860 (search_command): Use eassert.
1861 * syntax.c (struct lisp_parse_state): New member location_byte.
1862 (scan_sexps_forward): Record from_byte and avoid redundant
1863 character to byte position calculation ...
1864 (Fparse_partial_sexp): ... here. Break too long line.
1866 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1868 * lisp.h (make_uninit_vector): New function.
1869 * alloc.c (Fvector, Fmake_byte_code):

1888 argument is known to be a vector.
1889 * fns.c (Flocale_info): Likewise for ASET.
1890 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1891 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1893 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1895 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1898 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1899 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1900 updateCollectionBehaviour.
1902 * nsterm.m (NEW_STYLE_FS): Remove.
1903 (ns_last_use_native_fullscreen): New variable.
1904 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1905 (x_set_window_size): Do not take title bar and tool bar into account
1906 if isFullscreen returns YES.
1907 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1908 (check_native_fs): New function.
1909 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1910 (ns_term_init): Remove NEW_STYLE_FS.
1911 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1912 and tool bar if isFullscreen returns NO.
1913 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1914 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1915 with HAVE_NATIVE_FS.

1921 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1922 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1923 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1924 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1925 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1926 (syms_of_nsterm): Add ns-use-native-fullscreen.
1928 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1930 * fileio.c (Qchoose_write_coding_system): Now static.
1932 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1934 * xdisp.c (window_buffer_changed): region_showing can be negative,
1935 which still means region is being displayed.
1936 (redisplay_internal): Resurrect code that forced redisplay of the
1937 whole window when showing region and the mark has changed.
1938 Record the new mark position to allow redisplay optimizations.
1939 (display_line): If it->region_beg_charpos is non-zero, set the
1940 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1942 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1943 not bitfield of 1 bit.
1945 2013-02-03 Daniel Colascione <dancol@dancol.org>
1947 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1948 daemon mode works on cygw32 when Emacs is installed and not just
1951 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1953 Avoid file time stamp bug on MS-Windows (Bug#13149).
1954 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1955 as FAT32 doesn't update time stamps when truncating them.
1956 Also, check that a file time stamp is not a multiple of 100 ns;
1957 this should catch all instances of the problem on MS-Windows,
1958 as its native file system resolution is 100 ns or worse, and
1959 checking for a non-multiple of 100 ns should impose only a small
1960 overhead on systems with ns resolution.
1962 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1964 Avoid encoding file names on MS-Windows when they need to be run
1965 through dostounix_filename.
1966 * w32.c (normalize_filename): Accept an additional argument
1967 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1968 downcase it even if w32-downcase-file-names is non-nil.
1969 (dostounix_filename): Accept an additional argument MULTIBYTE and
1970 pass it to normalize_filename.
1971 (emacs_root_dir): Adjust.
1973 * msdos.h (dostounix_filename): Adjust prototype.
1975 * w32.h (dostounix_filename): Adjust prototype.
1977 * msdos.c (dostounix_filename): Accept an additional argument and
1979 (init_environment): Adjust callers of dostounix_filename.
1981 * fileio.c (Ffile_name_directory, file_name_as_directory)
1982 (directory_file_name, Fexpand_file_name)
1983 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1985 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1987 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1988 variables, as egetenv is case-insensitive for DOS_NT.
1990 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1991 with an encoded file name.
1993 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1994 Adjust calls to dostounix_filename.
1996 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1998 * unexw32.c (unexec): Adjust call to dostounix_filename.
2000 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2002 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2005 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2008 * callproc.c (Fcall_process): Make sure program name in PATH and
2009 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2010 is passed to exec/spawnve, which fails unless the file-name
2013 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2014 even if w32-quote-process-args is nil.
2016 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2018 Fix timestamp bug when write-region appends nothing (Bug#13149).
2019 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2020 the file's time stamp doesn't change if Emacs happens to write nothing
2021 to the file, and on a buggy file system this could cause Emacs to
2022 incorrectly infer that the file system doesn't have the bug.
2023 Avoid this problem by inhibiting the inference in this case.
2025 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2027 * window.h (struct window): Convert base_line_number, base_line_pos
2028 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2029 Convert region_showing member from Lisp_Object to bitfield.
2030 Remove sequence_number member. Adjust comments.
2031 * window.c (sequence_number): Remove.
2032 (make_window): Initialize column_number_displayed.
2033 * print.c (print_object): Follow the printed representation of
2034 frames and print window pointer to distinguish between windows.
2035 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2036 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2037 (wset_column_number_displayed, wset_region_showing): Remove.
2038 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2039 (try_scrolling, try_cursor_movement, redisplay_window)
2040 (try_window_reusing_current_matrix, try_window_id, display_line)
2041 (display_mode_lines, decode_mode_spec): Adjust users.
2042 * .gdbinit (pwinx): Do not print sequence_number.
2044 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2046 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2047 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2048 * dired.c: Include <fcntl.h>.
2049 (open_directory): New function, which uses open and fdopendir
2050 rather than opendir. DOS_NT platforms still use opendir, though.
2051 (directory_files_internal, file_name_completion): Use it.
2052 (file_attributes): New function, with most of the old Ffile_attributes.
2053 (directory_files_internal, Ffile_attributes): Use it.
2054 (file_attributes, file_name_completion_stat): First arg is now fd,
2055 not dir name. All uses changed. Use fstatat rather than lstat +
2057 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2058 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2059 (emacs_readlinkat): New function, with much of the old
2060 Ffile_symlink_p, but with an fd argument for speed.
2061 It uses readlinkat rather than careadlinkatcwd, so that it
2062 need not assume the working directory.
2063 (Ffile_symlink_p): Use it.
2064 * filelock.c (current_lock_owner): Use emacs_readlinkat
2065 rather than emacs_readlink.
2066 * lisp.h (emacs_readlinkat): New decl.
2067 (READLINK_BUFSIZE, emacs_readlink): Remove.
2068 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2069 (emacs_norealloc_allocator, emacs_readlink): Remove.
2070 This stuff is moved to fileio.c.
2071 * w32.c (fstatat, readlinkat): New functions.
2072 (careadlinkat): Don't check that fd == AT_FDCWD.
2073 (careadlinkatcwd): Remove; no longer needed.
2075 2013-01-31 Glenn Morris <rgm@gnu.org>
2077 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2078 (Fwrite_region): Update for new choose_write_coding_system args.
2079 Move the last piece of choose_write_coding_system here. (Bug#13522)
2080 (syms_of_fileio): Add choose-write-coding-system.
2082 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2084 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2085 (sys_close): Zero out the flags for the file descriptor before
2086 closing it. (Bug#13546)
2088 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2089 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2090 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2093 * w32.c (w32_get_long_filename, init_environment, readlink):
2094 Support file names encoded in DBCS codepages.
2095 (readlink): Use the current file-name-coding-system, not the ANSI
2096 codepage, to decode and handle targets of symlinks.
2098 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2100 * w32.c (opendir): Now accepts a 'const char *'.
2102 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2104 Remove obsolete redisplay code. See the discussion at
2105 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2106 * dispnew.c (preemption_period, preemption_next_check): Remove.
2107 (Vredisplay_preemption_period): Likewise.
2108 (update_frame, update_single_window, update_window, update_frame_1):
2109 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2110 used, following the 2012-06-22 change.
2112 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2114 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2116 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2118 * font.c (num_fonts): Remove the leftover from old
2119 debugging code. Adjust comment style here and there.
2120 * insdel.c (insert_1): Remove.
2121 * lisp.h (insert_1): Remove prototype.
2122 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2124 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2126 * w32.c (max_filename_mbslen): New function.
2127 (normalize_filename, readdir): Use it to detect locales where ANSI
2128 encoding of file names uses a double-byte character set (DBCS).
2129 If a DBCS encoding is used, advance by characters using
2130 CharNextExA, instead of incrementing a 'char *' pointer.
2131 Use _mbslwr instead of _strlwr. (Bug#13515)
2133 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2134 request of memory reservation to 1.7GB. (Bug#13065)
2136 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2138 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2139 at check_extra_latin label. (Bug#13505)
2141 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2143 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2144 Avoid redundant calls to strlen.
2146 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2148 Drop async_visible and async_iconified fields of struct frame.
2149 This is possible because async input is gone; for details, see
2150 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2151 * frame.h (struct frame): Remove async_visible and async_iconified
2152 members, convert garbaged to unsigned bitfield. Adjust comments.
2153 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2154 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2155 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2156 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2157 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2159 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2160 properly. Likewise for obscured.
2162 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2165 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2167 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2169 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2170 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2172 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2174 * xdisp.c (message2, message2_nolog): Remove functions.
2175 (message3, message3_nolog): Extract nbytes and multibyteness directly
2176 from the string. Change all callers.
2177 (message3_nolog): Don't set message_enable_multibyte since set_message
2178 will reset it anyway.
2179 (message1, message1_nolog): Use message3.
2180 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2181 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2182 (set_message): Drop all but the second arg, which has to be a string.
2183 (set_message_1): Simplify now that we know that a1 is NULL and the
2184 second arg is a string.
2185 * frame.h (struct frame): Remove `message_buf' field.
2186 Use glyphs_initialized_p instead.
2187 (FRAME_MESSAGE_BUF): Remove macro.
2188 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2189 * lisp.h (message2, message2_nolog): Remove declarations.
2190 (message3, message3_nolog): Update declarations.
2191 * keyboard.c (read_char_minibuf_menu_text)
2192 (read_char_minibuf_menu_width): Remove vars.
2193 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2194 to correctly handle multibyte strings.
2195 * frame.c (delete_frame): Don't free message_buf any more.
2196 * editfns.c (message_text, message_length): Remove vars.
2197 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2198 * fileio.c (auto_save_error): Use message3 instead of message2.
2199 * dispnew.c (adjust_frame_message_buffer): Remove function.
2201 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2203 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2204 real estate used for the tool bar and the menu bar.
2206 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2208 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2209 hidden buffer is prepared to modification (Bug#13164).
2211 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2213 * window.h (struct window): Change window_end_valid member from
2214 Lisp_Object to a bitfield. Adjust comments.
2215 (wset_window_end_valid): Remove.
2216 * window.c (adjust_window_count): Clear window_end_valid.
2217 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2218 (Fwindow_line_height, set_window_buffer, Frecenter)
2219 (Fsplit_window_internal, Fdelete_other_windows_internal)
2220 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2221 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2222 * xdisp.c (check_window_end, reconsider_clip_changes)
2223 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2224 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2225 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2227 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2229 * xdisp.c (mark_window_display_accurate): Simplify the loop
2230 assuming that the only one of vchild, hchild or buffer window
2231 slots is non-nil. Call mark_window_display_accurate_1 for
2232 the leaf windows only.
2233 (mark_window_display_accurate_1): Always assume leaf window.
2236 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2238 * emacs.c (Qkill_emacs_hook): Now static.
2240 * fileio.c (Finsert_file_contents): Simplify.
2241 Remove unnecessary assignments and tests.
2243 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2245 * w32.c (acl_set_file): Don't test for errors unless
2246 set_file_security returns FALSE. Avoids spurious errors when
2249 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2251 * fileio.c (Finsert_file_contents): Revert code introduced at
2252 2013-01-18 in favor of the simpler and generally better fix.
2253 Save stack space by removing 'buffer' and reusing 'read_buf'
2256 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2258 * lisp.h (eabs): Define unconditionally (Bug#13419).
2259 The old "#if !defined (eabs)" was an unnecessary revenant of back
2260 when this macro was called "abs". Document 'eabs' better.
2262 2013-01-19 Glenn Morris <rgm@gnu.org>
2264 * fns.c (Frandom): Doc fix.
2266 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2268 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2269 segfault when there are lots of overlays.
2271 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2272 when there are lots of overlays.
2273 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2274 for the details and a way to reproduce.
2276 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2278 * fileio.c: Use O_APPEND to append.
2279 This corresponds better to the natural interpretation of "append",
2280 and avoids the need to open the output file twice, or to invoke
2281 lseek when APPEND is neither nil nor a number.
2282 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2283 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2284 file possibly twice, and lseeking to its end; this avoids the
2285 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2286 at the same time: the combination is never needed and apparently
2287 it doesn't work with DOS_NT.
2289 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2290 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2292 Allow floating-point file offsets.
2293 Problem reported by Vitalie Spinu in
2294 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2295 * fileio.c (emacs_lseek): Remove.
2296 (file_offset): New function.
2297 (Finsert_file_contents, Fwrite_region): Use it.
2299 2013-01-19 Chong Yidong <cyd@gnu.org>
2301 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2302 aborting on Fsignal (Bug#13289).
2304 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2306 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2307 set_file_security as failure due to insufficient privileges.
2308 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2309 (fstat): Return owner and group like 'stat' and 'lstat' do.
2311 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2313 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2314 The bug was observed on Ubuntu operating inside a virtual machine,
2315 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2316 The workaround introduces a race condition on non-buggy hosts,
2317 but it's an unlikely race and anyway there's a nearly identical
2318 nearby race that can't be fixed.
2319 * fileio.c (valid_timestamp_file_system, timestamp_file_system):

2783 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2785 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2786 (xg_create_tool_bar): Adjust users.
2788 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2790 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2791 * buffer.c (Fget_buffer_create): Use it to set compact field of
2792 struct buffer_text to avoid accessing an uninitialized value
2793 when compact_buffer is called for the first time.
2794 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2795 (Fset_buffer_modified_p): Use buffer_window_count to check
2796 whether the buffer is displayed in some window.
2797 * xdisp.c (message_dolog): Likewise.
2799 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2801 * w32.c (acl_set_file): If setting the file security descriptor
2802 fails, and the new DACL is identical to the existing one, silently
2803 return success. This fixes problems for users backing up their
2804 own files without having the necessary privileges for setting
2805 security descriptors.
2807 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2809 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2810 after WaitForSingleObject returns normally. This expedites reader
2811 thread shutdown when delete_child triggers it.
2812 (reap_subprocess): More accurate commentary for why we call
2813 delete_child only when cp->fd is negative.
2815 * w32.c (sys_close): Do not call delete_child on a subprocess
2816 whose handle is not yet closed. Instead, set its file descriptor
2817 to a negative value, so that reap_subprocess will call
2818 delete_child on that subprocess when its SIGCHLD arrives.
2819 This avoids closing handles used for communications between sys_select
2820 and reader_thread, which doesn't give sys_select a chance to
2821 notice that the process exited and invoke the SIGCHLD handler for
2824 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2826 * nsfns.m (Fns_do_applescript): Run event loop until script has
2827 been executed (Bug#12969).
2828 (ns_run_ascript): Chech as_script for nil, set to nil after
2831 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2833 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2835 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2837 * w32term.c (w32fullscreen_hook): New function.
2838 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2840 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2842 * fileio.c (Finsert_file_contents): Doc fix.
2844 * w32proc.c (new_child, delete_child, find_child_pid): For a
2845 subprocess, consider its slot being in use as long as its process
2846 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2847 slot when a new process is started immediately after killing
2848 another one, without waiting enough time for the first process to
2849 be reaped and resources allocated for it be orderly freed.
2851 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2853 2012-12-21 Chong Yidong <cyd@gnu.org>
2855 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2857 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2859 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2861 * w32.c (get_name_and_id): Always pass NULL as the first argument
2862 of lookup_account_sid. Avoids crashes with UNC file names that
2863 refer to DFS domains, not to specific machine names. (Bug#12621)
2864 Remove now unused argument FNAME; all callers changed.
2865 (get_file_owner_and_group): Remove now unused argument FNAME; all
2868 2012-12-21 Chong Yidong <cyd@gnu.org>
2870 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2871 error for invalid chars, don't check for a nil return value.
2873 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2875 Avoid calls to CHAR_TO_BYTE if byte position is known.
2876 * editfns.c (make_buffer_string_both): Use move_gap_both.
2877 (Fbuffer_string): Use make_buffer_string_both.
2878 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2880 (buf_bytepos_to_charpos): Likewise.
2881 (charpos_to_bytepos): Remove.
2882 * fileio.c (Finsert_file_contents): Use move_gap_both.
2883 * search.c (Freplace_match): Likewise.
2884 * process.c (process_send_region): Likewise. Use convenient
2885 names for byte positions.
2886 * lisp.h (charpos_to_bytepos): Remove prototype.
2887 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2888 * insdel.c (move_gap): Likewise.
2890 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2892 * xdisp.c (redisplay_internal): Remove now-unused local.
2894 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2896 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2897 (redisplay_internal): Don't bother selecting the frame to get the
2898 proper value of frame-local variables (bug#13225).
2900 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2902 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2903 Rename 4th argument since it may be buffer or string. Adjust comment.
2904 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2906 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2908 * coding.c (Fdetect_coding_region): Do not check start and end with
2909 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2910 (code_convert_region): Likewise.
2912 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2914 * w32.c (acl_get_file, acl_set_file): Run the file name through
2915 map_w32_filename, and resolve any symlinks in the file name, like
2917 (acl_set_file): Call revert_to_self, if any privileges were
2920 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2922 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2923 ($(BLD)/w32.$(O)): Update dependencies.
2925 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2927 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2928 propagate redisplay's scrolling (if any) to the right window.
2929 (redisplay_internal): Use ensure_selected_frame.
2930 (display_mode_lines): Complete last fix.
2931 * window.c (select_window_1): New func, extracted from select_window.
2932 (select_window): Use it.
2933 * window.h (select_window_1): Declare.
2935 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2937 Emulate Posix ACL APIs on MS-Windows.
2938 * w32.c: Include sddl.h and sys/acl.h.
2939 (SDDL_REVISION_1): Define if not already defined.
2940 (g_b_init_get_security_descriptor_dacl)
2941 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2942 (g_b_init_is_valid_security_descriptor)
2943 (g_b_init_set_file_security): New static flags.

2955 (acl_free, acl_get_file, acl_set_file): New functions.
2957 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2959 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2961 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2962 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2963 for some of that bug's symptoms can now cause Emacs to abort.
2964 Remove the workaround.
2965 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2966 The bug that caused SIGCHLD to get lost has been fixed, and the
2967 workaround for it can now cause Emacs to abort.
2969 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2971 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2972 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2973 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2975 2012-12-16 Romain Francoise <romain@orebokech.com>
2977 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2978 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2979 and copy ACL entries of file in addition to SELinux context if set.
2980 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2982 * Makefile.in (LIBACL_LIBS): New macro.
2985 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2987 * fileio.c (internal_delete_file): Use bool for boolean.
2989 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2991 Fix bug #13079 on MS-Windows with temp files not being deleted.

2994 (register_child): First argument is now pid_t.
2995 (record_infile, record_pending_deletion): New prototypes.
2997 * w32proc.c (new_child): Initialize input_file and
2998 pending_deletion members of the child.
2999 (delete_child): Delete the child's temporary input file, if any,
3000 that is pending deletion.
3001 (register_child): First argument is now pid_t.
3002 (record_infile, record_pending_deletion): New functions.
3003 (reap_subprocess): Fix a typo in DebPrint string.
3004 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3006 * fileio.c (internal_delete_file): Return an int again: non-zero
3007 if delete-file succeeds, zero otherwise.
3009 * lisp.h (internal_delete_file): Adjust prototype.
3011 * callproc.c (Fcall_process): Don't overwrite infile with result
3013 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3014 asynchronous subprocess, record the name of the input file name,
3016 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3017 delete the file, record it as pending deletion when the subprocess
3020 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3022 * editfns.c [HAVE_PWD_H]: Include grp.h.
3024 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3026 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3028 Fix permissions bugs with setgid directories etc. (Bug#13125)
3029 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3030 to mark it as a placeholder. The old value was often wrong.
3031 The only user of this attribute has been changed to use
3032 file-ownership-preserved-p instead, with its new group arg.
3033 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3035 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

3040 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3042 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3043 try to get accurate owner and group information from NT file
3044 security APIs. This is to make most callers of 'stat' and
3045 'lstat', which don't need that information, much faster.
3047 * dired.c (Ffile_attributes) [WINDOWSNT]:
3048 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3049 owner and group information from 'lstat'.
3051 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3053 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3054 as that confuses set-auto-coding, so insist on the head-read
3055 returning the full 1024 bytes. Let lseek compute the tail offset;
3056 less work for us. Do not ignore I/O errors when reading the tail.
3058 * xdisp.c: Minor style fixes.
3059 (init_iterator): Hoist assignment out of if-expression.
3060 (markpos_of_region): Callers now test for sign, not for -1.

3065 * xdisp.c (markpos_of_region): New function.
3066 (init_iterator): Do not highlight the region of zero length.
3067 (redisplay_window): Check whether the region is of non-zero length.
3068 (try_cursor_movement): Allow if the region length is zero.
3069 (try_window_reusing_current_matrix, try_window_id): Likewise.
3071 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3073 * search.c (search_buffer): Check the inverse translations of each
3074 character in pattern when the buffer being searched is unibyte.
3077 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3079 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3080 files, fixing a regression from 24.2.
3081 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3083 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3085 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3086 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3087 Remove unnecessary S_ISLNK test, as (contra the comments) this
3088 function can't copy symlinks. Improve quality of error message
3089 when attempting to copy files that are neither regular files nor

3097 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3098 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3100 2012-12-12 Daniel Colascione <dancol@dancol.org>
3102 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3103 the dumped Emacs is not a sparse file, greatly improving Cygwin
3104 "make bootstrap" performance.
3106 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3108 * inotify.c (inotify_callback): Generate an Emacs event for every
3109 incoming inotify event.
3111 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3113 * xdisp.c (handle_face_prop): Fix logic of computing
3114 it->start_of_box_run_p.
3115 (append_space_for_newline): If the glyph row is R2L, reset the
3116 iterator's end_of_box_run_p flag before prepending the space glyph.
3117 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3118 iterator's start_of_box_run_p flag before prepending the stretch.
3119 (append_glyph, produce_image_glyph, append_composite_glyph)
3120 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3121 left_box_line_p and right_box_line_p flags of the glyph for R2L
3122 glyph rows. (Bug#13011)
3124 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

3129 * window.c (replace_buffer_in_windows_safely): Do nothing
3130 if buffer is not shown in a window.

3136 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3137 encoded_file_name, which is what it is.
3139 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3141 Consistently use marker_position and marker_byte_position.

3150 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
3151 Replace direct access to marker fields with calls
3152 to marker_position and/or marker_byte_position.

3165 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3168 * w32fns.c (cache_system_info): Initialize the global hinst
3169 variable here so various initialization calls DTRT.
3171 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3172 (hinst): Remove unneeded extern declaration.
3173 (_start): Remove initialization of above variables; remove
3174 initialization of hinst, as cache_system_info now does that.

3180 Teach the autoconf build system how to compile a Windows resource file
3181 and link it to Emacs.

3283 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
3285 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
3287 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
3288 DWORD_PTR, for compatibility with 64-bit builds.
3290 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
3291 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
3292 (system_process_attributes): Use SIZE_T rather than DWORD, for

3299 2012-12-10 Eli Zaretskii <eliz@gnu.org>
3301 * indent.c (Fvertical_motion): If a display string will be
3302 displayed on the left or the right margin, don't consider it as a
3303 factor in cursor positioning. (Bug#13108)
3305 2012-12-10 Martin Rudalics <rudalics@gmx.at>
3307 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
3309 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

3314 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3316 * w32.c (unsetenv): Return 0 if the input string is too long.
3318 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3320 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3321 * alloc.c (xputenv): New function.
3322 * dbusbind.c (Fdbus_init_bus):
3324 * xterm.c (x_term_init):
3325 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

3327 (tzvalbuf_in_environ): New static var.
3328 (init_editfns): Initialize these two static vars.
3329 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
3330 Save old TZ value on stack, if it's small.
3331 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
3332 instead, use xputenv+unsetenv to set and restore TZ.
3333 (environbuf): Remove static var. All uses removed.
3334 (Fset_time_zone_rule): Do not save TZ and environ;
3335 no longer needed here.
3336 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3337 Move to inside set_time_zone_rule; they don't need file scope any more.
3338 (set_time_zone_rule): Maintain the TZ=value string separately.
3339 (syms_of_editfns): Don't initialize initial_tz;
3340 init_editfns now does it.
3341 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3342 * lisp.h (xputenv): New decl.
3344 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3346 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3348 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3350 * w32.c (unsetenv, sys_putenv): New functions.
3352 2012-12-08 Chong Yidong <cyd@gnu.org>
3354 * editfns.c (Finsert_char): Make the error message more
3355 informative (Bug#12992).
3357 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3359 Simplify get_lim_data.
3360 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3361 Remove USG and vlimit methods; no longer used these days.
3362 Add #error catchall just in case.
3364 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3365 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3366 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3367 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3368 (deleted_pid_list, Fdelete_process, create_process)
3369 (record_child_status_change, handle_child_signal, deliver_child_signal)
3370 (init_process_emacs, syms_of_process):
3371 Assume SIGCHLD is defined.
3372 (parse_signal): Remove. All uses removed.
3373 (abbr_to_signal): New static function.
3374 (Fsignal_process): Use it to convert signal names to ints.
3375 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3376 kill (getpgrp (), ...).
3377 (emacs_sigaction_init): Assume SIGCHLD is defined.
3378 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3379 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

3381 All uses replaced by 'kill' with a negative pid.
3382 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3383 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3385 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3387 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3388 This will cause a production Emacs to dump core instead of
3391 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3393 * frame.c (make_frame): Do not set window's buffer to t.
3394 * window.c (Fsplit_window_internal): Likewise. Previously it was
3395 used to indicate that the window is being set up. Now we use
3396 set_window_buffer for all new windows, so the condition in ...
3397 (Fset_window_buffer): ... is always true and can be removed.
3399 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3401 Convenient macro to check whether the buffer is hidden.
3402 * buffer.h (BUFFER_HIDDEN_P): New macro.
3403 * frame.c (make_frame): Use it. Adjust comment.
3404 * buffer.c (candidate_buffer): New function.
3405 (Fother_buffer, other_buffer_safely): Use it.
3407 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3409 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3410 if the child process is still running. Instead, exit the wait
3411 loop and return zero. (Bug#13086)
3413 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3415 * frame.h (x_char_width, x_char_height): Remove prototypes.
3416 * w32term.h (x_char_width, x_char_height): Likewise.
3417 * xfns.c (x_char_width, x_char_height): Remove.
3418 * w32fns.c (x_char_width, x_char_height): Likewise.
3419 * nsfns.c (x_char_width, x_char_height): Likewise.

3426 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3428 Fix a recently-introduced delete-process race condition.
3429 * callproc.c, process.h (record_kill_process):
3430 New function, containing part of the old call_process_kill.
3431 (call_process_kill): Use it.
3432 This does not change call_process_kill's behavior.
3433 * process.c (Fdelete_process): Use record_kill_process to fix a
3434 race condition that could cause Emacs to lose track of a child.
3436 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3438 Avoid code duplication between prev_frame and next_frame.
3439 * frame.c (candidate_frame): New function. Add comment.
3440 (prev_frame, next_frame): Use it. Adjust comment.
3442 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3444 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3445 fails, signal an error instead of continuing with an empty
3447 Encode expanded temp file pattern before passing it to mkstemp or
3450 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3451 Encode the file name before passing it to dostounix_filename, in
3452 case it will downcase it (under w32-downcase-file-names).
3455 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3457 Minor call-process cleanups.
3458 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3459 at the same time as other platforms, to simplify analysis.
3460 No need for fd0_volatile since we have synch_process_fd.
3461 Avoid needless emacs_close; arg is always negative.
3463 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3465 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3468 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3470 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3471 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3472 and mouse_face_hidden members to a bitfields.
3473 * frame.h (struct frame): Remove set-but-not-used space_width member.
3474 (FRAME_SPACE_WIDTH): Remove.
3475 * nsterm.m, w32term.c, xterm.c: Adjust users.
3476 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3477 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3478 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3479 members to a bitfields.
3481 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3483 Don't let call-process be a zombie factory (Bug#12980).
3484 Fixing this bug required some cleanup of the signal-handling code.
3485 As a side effect, this change also fixes a longstanding rare race
3486 condition whereby Emacs could mistakenly kill unrelated processes,
3487 and it fixes a bug where a second C-g does not kill a recalcitrant
3488 synchronous process in GNU/Linux and similar platforms.
3489 The patch should also fix the last vestiges of Bug#9488,
3490 a bug which has mostly been fixed on the trunk by other changes.
3491 * callproc.c, process.h (synch_process_alive, synch_process_death)
3492 (synch_process_termsig, sync_process_retcode):
3493 Remove. All uses removed, to simplify analysis and so that
3494 less consing is done inside critical sections.
3495 * callproc.c (call_process_exited): Remove. All uses replaced
3496 with !synch_process_pid.
3497 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3498 These take the role of what used to be in unwind-protect arg.
3500 (block_child_signal, unblock_child_signal):
3501 New functions, to avoid races that could kill innocent-victim processes.
3502 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3503 (call_process_kill): Record killed processes as deleted, so that
3504 zombies do not clutter up the system. Do this inside a critical
3505 section, to avoid a race that would allow the clutter.
3506 (call_process_cleanup): Fix code so that the second C-g works again
3507 on common platforms such as GNU/Linux.
3508 (Fcall_process): Create the child process in a critical section,
3509 to fix a race condition. If creating an asynchronous process,
3510 record it as deleted so that zombies do not clutter up the system.
3511 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3512 light of these changes. Omit unnecessary call to emacs_close
3513 before failure, as the unwind-protect code does that.
3514 * callproc.c (call_process_cleanup):
3515 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3516 * process.c (record_deleted_pid): New function, containing
3517 code refactored out of Fdelete_process.
3518 (Fdelete_process): Use it.
3519 (process_status_retrieved): Remove. All callers changed to use
3520 child_status_change.
3521 (record_child_status_change): Remove, folding its contents into ...
3522 (handle_child_signal): ... this signal handler. Now, this
3523 function is purely a handler for SIGCHLD, and is not called after
3524 a synchronous waitpid returns; the synchronous code is moved to
3525 wait_for_termination. There is no need to worry about reaping
3526 more than one child now.
3527 * sysdep.c (get_child_status, child_status_changed): New functions.
3528 (wait_for_termination): Now takes int * status and bool
3529 interruptible arguments, too. Do not record child status change;
3530 that's now the caller's responsibility. All callers changed.
3531 Reimplement in terms of get_child_status.
3532 (wait_for_termination_1, interruptible_wait_for_termination):
3533 Remove. All callers changed to use wait_for_termination.
3534 * syswait.h: Include <stdbool.h>, for bool.
3535 (record_child_status_change, interruptible_wait_for_termination):
3537 (record_deleted_pid, child_status_changed): New decls.
3538 (wait_for_termination): Adjust to API changes noted above.
3540 * bytecode.c, lisp.h (Qbytecode): Remove.
3541 No longer needed after 2012-11-20 interactive-p changes.
3543 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3545 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3546 the scroll margin, move point outside the margin. (Bug#13055)
3548 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3550 * gtkutil.c (my_log_handler): New function.
3551 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3553 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3555 * lisp.h (modify_region): Rename to...
3556 (modify_region_1): ...new prototype.
3557 * textprop.c (modify_region): Now static. Adjust users.
3558 * insdel.c (modify_region): Rename to...
3559 (modify_region_1): ...new function to work with current buffer.
3560 Adjust comment and users. Use true and false for booleans.
3562 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3564 * alloc.c (free_save_value): New function.
3565 (safe_alloca_unwind): Use it.
3566 * lisp.h (free_save_value): New prototype.
3567 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3569 (save_excursion_restore): Adjust to match saved data structure.
3570 Use free_save_value to offload some work from GC. Drop obsolete
3573 2012-12-03 Chong Yidong <cyd@gnu.org>
3575 * fileio.c (Vauto_save_list_file_name): Doc fix.
3577 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3579 * w32fns.c: Remove prototype of atof.
3580 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3582 (file_dialog_callback): Make it UINT_PTR.
3584 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3587 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3588 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3591 2012-12-03 Glenn Morris <rgm@gnu.org>
3593 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3595 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3597 Fix xpalloc confusion after memory is exhausted.
3598 * alloc.c (xpalloc): Comment fix.
3599 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3600 and signals an error, do not clear charset_table_size, as
3601 charset_table is still valid.
3602 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3604 Use execve to avoid need to munge environ (Bug#13054).
3605 * callproc.c (Fcall_process):
3606 * process.c (create_process):
3607 Don't save and restore environ; no longer needed.
3608 * callproc.c (child_setup):
3609 Use execve, not execvp, to preserve environ.
3611 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3613 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3615 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3617 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3618 display for sliced images (Bug#10500).
3620 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3622 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3624 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3625 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3627 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3629 * xdisp.c (window_outdated): Remove eassert since it hits
3630 some suspicious corner cases (see Bug#13007 and Bug#13012).
3631 (mode_line_update_needed): New function.
3632 (redisplay_internal, redisplay_window): Use it.
3633 (ensure_selected_frame): New function.
3634 (redisplay_internal, unwind_redisplay): Use it.
3635 (redisplay_internal): Move comment about buffer_shared...
3636 (buffer_shared_and_changed): ...near to its real use.
3638 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3640 * callproc.c (Fcall_process): Don't misreport vfork failure.
3642 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3644 * callproc.c (Fcall_process): Fix vfork portability problems.
3645 Do not assume that fd[0], count, filefd, and save_environ survive
3646 vfork. Fix bug whereby wrong errno value could be reported for
3647 pipe failure. Some minor cleanups, too, as follows. Move buf and
3648 bufsize to the context where they're needed. Change new_argv to
3649 be of type char **, as this is more convenient and avoids casts.
3650 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3651 Now local constants, not macros.
3653 2012-11-18 Kenichi Handa <handa@gnu.org>
3655 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3656 for the variable "f".
3658 2012-11-13 Kenichi Handa <handa@gnu.org>
3660 * font.c (font_unparse_xlfd): Exclude special characters from the
3661 generating XLFD name.
3663 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3665 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
3666 * dired.c (stat_uname, stat_gname):
3667 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3669 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).
3670 * dired.c (directory_files_internal, file_name_completion):
3671 Assume EAGAIN and EINTR are defined.
3673 * fileio.c (Fcopy_file): Assume EISDIR is defined.
3674 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
3675 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3676 * lread.c (readbyte_from_file): Assume EINTR is defined.
3677 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3678 Assume EIO and EAGAIN are defined.
3679 * unexcoff.c (write_segment): Assume EFAULT is defined.
3681 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3683 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3686 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3687 highlighting on the frame was cleared. Prevents assertion
3688 violations when repeatedly clicking on the "Top" link of the
3689 "bread-crumbs" in Info buffers.
3691 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3693 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3695 2012-11-24 Ken Brown <kbrown@cornell.edu>
3697 * keyboard.c (HAVE_MOUSE):
3698 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3699 were always defined.
3701 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3703 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3704 between bpos_covered and bpos_max. This fixes cursor display when
3705 several display strings follow each other.
3707 * .gdbinit (pgx): If the glyph's object is a string, display the
3708 pointer to string data, rather than the value of the string object
3709 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3711 * indent.c (Fvertical_motion): If the starting position is covered
3712 by a display string, return to one position before that, to avoid
3713 overshooting it inside move_it_to. (Bug#12930)
3715 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3717 * frame.h (struct frame): Remove display_preempted member
3718 since all users are dead long ago.

3720 * w32menu.c (pending_menu_activation): Remove since not
3722 (set_frame_menubar): Adjust user.
3723 * w32term.h (struct x_output): Drop outdated #if 0 code.
3724 (struct w32_output): Use bitfields for explicit_parent,
3725 asked_for_visible and menubar_active members.
3726 Drop unused pending_menu_activation member.
3727 * xterm.h (struct x_output): Drop outdated #if 0 code.
3728 Use bitfields for explicit_parent, asked_for_visible,
3729 has_been_visible and net_wm_state_hidden_seen members.
3731 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3733 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3734 of a literal "/". (Bug#12955)
3735 (gl-stamp): Invoke fc.exe directly, not through cmd.
3737 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3739 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3740 * dired.c: Assume HAVE_DIRENT_H.
3741 (NAMLEN): Remove, replacing with ...
3742 (dirent_namelen): New function. All uses changed. Use the GNU macro
3743 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3744 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3745 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3746 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3748 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3749 * ndir.h: Rename to ../nt/inc/dirent.h.
3750 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3751 Do not include <dirent.h>; no longer needed.
3752 * w32.c: Include <dirent.h> rather than "ndir.h".
3754 2012-11-23 Chong Yidong <cyd@gnu.org>
3756 * xftfont.c (xftfont_open): Remove duplicate assignment.
3758 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3760 * alloc.c (Fgarbage_collect): Unblock input after clearing
3761 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3762 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3763 * msdos.c (IT_frame_up_to_date): Use it here...
3764 * w32term.c (w32_frame_up_to_date): ...here...
3765 * xterm.c (XTframe_up_to_date): ...and here...
3766 * nsterm.m (ns_frame_up_to_date): ...but not here.
3767 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3769 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3770 Do not check whether GC is in progress.
3772 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3774 * xdisp.c (window_buffer_changed): New function.
3775 (update_menu_bar, update_tool_bar): Use it to
3776 simplify large 'if' statements.
3777 (redisplay_internal): Generalize commonly used
3778 'tail' and 'frame' local variables.
3780 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3782 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3783 with Windows system header.
3785 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3787 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3788 * alloc.c: Assume unistd.h exists.
3789 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3790 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3791 (getwd) [USG]: Remove; no longer needed.
3792 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3793 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3794 * w32.h (getcwd): Remove decl.
3796 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3798 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3799 Make it set selected_window as well.
3800 (update_tool_bar): Use it.
3802 2012-11-21 Ken Brown <kbrown@cornell.edu>
3804 * emacs.c (main): Set the G_SLICE environment variable for all
3805 Cygwin builds, not just GTK builds. See
3806 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3808 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3810 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3811 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3812 Define for the MSVC compiler.
3814 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3816 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3817 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3818 dostounix_filename. Prevents crashes down the road, because
3819 dostounix_filename assumes it gets a unibyte string.
3820 Reported by Michel de Ruiter <michel@sentient.nl>, see
3821 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3823 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3827 * lread.c (init_obarray): Set `function' fields to Qnil.
3828 * eval.c (Fcommandp): Ignore Qunbound.
3829 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3830 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3831 Test NILP rather than Qunbound.
3832 (Ffmakunbound): Set to Qnil.
3833 (Fsymbol_function): Never signal an error.
3834 (Finteractive_form): Ignore Qunbound.
3836 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3838 * eval.c (interactive_p): Remove no-longer-used decl.
3840 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3842 * xdisp.c (buffer_shared): Adjust comment.
3843 (buffer_shared_and_changed): New function.
3844 (prepare_menu_bars, redisplay_internal): Use it to
3845 decide whether all windows or frames should be updated.
3846 (window_outdated): New function.
3847 (text_outside_line_unchanged_p, redisplay_window): Use it.
3848 (redisplay_internal): Likewise. Fix indentation.
3850 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3852 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3853 (syms_of_eval): Remove corresponding defsubr.
3854 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3856 2012-11-19 Daniel Colascione <dancol@dancol.org>
3858 * w32fns.c (Fx_file_dialog):
3859 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3860 cygwin_convert_file_name*.
3862 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3863 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3865 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3867 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3869 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3871 * w32select.c: Include w32common.h before w32term.h, so that
3872 windows.h gets included before w32term.h uses some of its
3873 features, see below.
3875 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3877 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3879 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3881 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3883 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3884 (ns_select): Return at once if events are held (Bug#12834).
3886 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3888 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3889 Needed following 2012-10-20 change. (Bug#12902)
3891 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3893 * w32proc.c (waitpid): Remove unused label get_result.
3895 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3897 * makefile.w32-in (SYSWAIT_H): New macro.
3898 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3899 ($(BLD)/sysdep.$(O)): Update dependencies.
3901 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3903 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3904 * callproc.c (relocate_fd): Assume F_DUPFD.
3905 * emacs.c, term.c (O_RDWR): Remove.
3906 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3907 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3908 * nsterm.m: Assume <fcntl.h> exists.
3909 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3910 (create_pty, Fmake_network_process, server_accept_connection)
3911 (wait_reading_process_output, init_process_emacs):
3913 (wait_reading_process_output): Put in a special case for WINDOWSNT
3914 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3915 It's not clear this is needed, but it's a more-conservative change.
3916 (create_process): Assume FD_CLOEXEC.
3917 (create_process, create_pty): Assume O_NOCTTY.
3918 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3919 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3920 Omit if not DOS_NT, since F_GETFL is not defined there.
3921 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3922 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3924 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3925 lack it, since gnulib guarantees this.
3926 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3928 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3930 * w32.c (faccessat): Pretend that directories have the execute bit
3931 set. Emacs expects that, e.g., in files.el:cd-absolute.
3933 * w32proc.c (create_child): Don't clip the PID of the child
3934 process to fit into an Emacs integer, as this is no longer a
3936 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3937 reaping only the process specified by PID argument, if that is
3938 positive. Use PID instead of dead_child to know which process to
3939 reap. Wait for the child to die only if WNOHANG is not in
3941 (sys_select): Don't set dead_child.
3943 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3944 as it is no longer needed.
3946 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3948 (record_child_status_change): Remove the setting of
3949 record_at_most_one_child for the !WNOHANG case.
3951 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3953 Fix problems in ns port found by static checking.
3954 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3955 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3956 not to process group.
3957 (ns_select): Use emacs_write, not write, as that's more robust
3958 in the presence of signals.
3959 (fd_handler:): Check for read errors.
3961 2012-11-16 Glenn Morris <rgm@gnu.org>
3963 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3965 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3967 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3969 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3971 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3972 use the same value of thread handle.
3973 (start_timer_thread): If the timer thread exited (due to error),
3974 clean up by closing the two handles it used. Duplicate the caller
3975 thread's handle here, so it gets duplicated only once, when
3976 launching the timer thread. Set priority of the timer thread, not
3978 (getitimer): Don't duplicate the caller thread's handle here.
3981 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3983 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3986 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3988 Remove no-longer-used pty_max_bytes variable.
3989 * process.c (pty_max_bytes): Remove; unused.
3990 (send_process): Do not set it.
3992 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3994 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3995 Update dependencies.
3997 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3999 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4000 This follows up on the 2012-09-29 patch that removed indirection
4001 for the 'function' field. Reported by Sergey Vinokurov in
4002 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4004 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4006 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4007 different name, as the MS runtime does not have such a function,
4008 and probably never will.) All callers changed. Ignore DIRFD
4009 value if PATH is an absolute file name, to match Posix spec
4010 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4013 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4015 * xdisp.c (echo_area_display, redisplay_internal):
4016 Omit redundant check whether frame_garbaged is set.
4018 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4020 Use faccessat, not access, when checking file permissions (Bug#12632).
4021 This fixes a bug that has been present in Emacs since its creation.
4022 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4023 which must set some sort of record. (Torek's bug report was against
4024 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4025 same common flaw.) See Torek's Usenet posting
4026 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4027 Posted: Fri Apr 8 14:18:56 1983.
4028 * Makefile.in (LIB_EACCESS): New macro.
4030 * callproc.c (init_callproc):
4031 * charset.c (init_charset):
4032 * fileio.c (check_existing, check_executable, check_writable)
4034 * lread.c (openp, load_path_check):
4035 * process.c (allocate_pty):
4037 Use effective UID when checking permissions, not real UID.
4038 * callproc.c (init_callproc):
4039 * charset.c (init_charset):
4040 * lread.c (load_path_check, init_lread):
4041 Test whether directories are accessible, not merely whether they exist.
4042 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4043 * fileio.c (check_existing, check_executable, check_writable)
4045 Use symbolic names instead of integers for the flags, as they're
4047 (check_writable): New arg AMODE. All uses changed.
4048 Set errno on failure.
4049 (Ffile_readable_p): Use faccessat, not stat + open + close.
4050 (Ffile_writable_p): No need to call check_existing + check_writable.
4051 Just call check_writable and then look at errno. This saves a syscall.
4052 dir should never be nil; replace an unnecessary runtime check
4053 with an eassert. When checking the parent directory of a nonexistent
4054 file, check that the directory is searchable as well as writable, as
4055 we can't create files in unsearchable directories.
4056 (file_directory_p): New function, which uses 'stat' on most platforms
4057 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4058 (Ffile_directory_p, Fset_file_times): Use it.
4059 (file_accessible_directory_p): New function, which uses a single
4060 syscall for efficiency.
4061 (Ffile_accessible_directory_p): Use it.
4062 * xrdb.c (file_p): Use file_directory_p.
4063 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4064 * lread.c (openp): When opening a file, use fstat rather than
4065 stat, as that avoids a permissions race. When not opening a file,
4066 use file_directory_p rather than stat.
4067 (dir_warning): First arg is now a usage string, not a format.
4068 Use errno. All uses changed.
4069 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4070 that merely introduced a race.
4071 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4072 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4073 and similarly for the other O_* flags.
4074 * w32.c (sys_faccessat): Rename from sys_access and switch to
4075 faccessat's API. All uses changed.
4076 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4077 (magic_db): Rename from magic_file_p.
4078 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4079 char *, so that we don't have to test for file existence
4080 separately from opening the file for reading. This removes a race
4081 fixes a permission-checking problem, and simplifies the code.
4083 (file_p): Remove; no longer needed.
4085 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4087 Omit glyphs initialization at startup.
4088 * dispnew.c (glyphs_initialized_initially_p): Remove.
4089 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4090 (Fredraw_frame): Move actual code from here...
4091 (redraw_frame): ...to here. Add eassert. Adjust comment.
4092 (Fredraw_display): Use redraw_frame.
4093 * xdisp.c (clear_garbaged_frames): Likewise.
4095 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4097 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4098 passed to pint2str and pint2hrstr to be at most the size of the
4099 frame's decode_mode_spec_buffer. This avoids crashes with very
4100 large values of FIELD_WIDTH argument to decode_mode_spec.
4103 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4105 Fix a race with verify-visited-file-modtime (Bug#12863).
4106 Since at least 1991 Emacs has ignored an mtime difference of no
4107 more than one second, but my guess is that this was to work around
4108 file system bugs that were fixed long ago. Since the race is
4109 causing problems now, let's remove that code.
4110 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4111 whose time stamp is off by no more than a second. Insist that the
4112 file time stamps match exactly.
4114 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4116 * frame.h (struct frame): Convert external_tool_bar member to
4117 1-bit unsigned bitfield.
4118 * termhooks.h (struct terminal): Remove mouse_moved member since
4119 all users are long dead. Adjust comment on mouse_position_hook.
4121 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4123 Simplify by using FOR_EACH_FRAME here and there.
4124 * frame.c (next_frame, prev_frame, other_visible_frames)
4125 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4126 * w32term.c (x_window_to_scroll_bar): Likewise.
4127 * window.c (window_list): Likewise.
4128 * xdisp.c (x_consider_frame_title): Likewise.
4129 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4130 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4131 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4132 * xmenu.c (menubar_id_to_frame): Likewise.
4133 * xselect.c (frame_for_x_selection): Likewise.
4134 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4135 (x_window_to_menu_bar): Likewise.
4136 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4138 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4140 * data.c (Qdefalias_fset_function): Now static.
4142 Another tweak to vectorlike_header change.
4143 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4144 Remove, and replace all uses with ...
4145 (next_in_free_list, set_next_in_free_list):
4146 New functions, which respect C's aliasing rules better.
4148 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4150 * window.c (list4i): Rename from 'quad'. All uses changed.
4151 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4153 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4155 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4156 warning about mixing declarations and code in ISO C90.
4158 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4160 * window.c (Fsplit_window_internal): Set combination limit of
4161 new parent window to t iff Vwindow_combination_limit is t;
4162 fixing a regression introduced with the change from 2012-09-22.
4163 (Fset_window_combination_limit): Fix doc-string.
4165 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4167 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4168 amount when the scroll margins are too large. When scrolling
4169 backwards in the buffer, give up if cannot reach point or the
4170 scroll margin within a reasonable number of screen lines.
4171 Fixes point position in window under scroll-up/down-aggressively when
4172 point is positioned many lines beyond the window top/bottom.
4175 * ralloc.c (relinquish): If real_morecore fails to return memory
4176 to the system, don't crash; instead, leave the last heap

4188 (Qdefalias_fset_function): New var.
4190 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>

4202 (SCROLL_BAR_VEC_SIZE): Remove.
4203 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4205 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4207 Tweak last vectorlike_header change.
4208 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4209 vectorlike object on the free list. This is introduced to avoid
4210 some (but not all) pointer casting and aliasing problems, see
4211 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4212 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4216 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4218 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4219 been removed, so remove them here also.

4241 * lisp.h (sxhash_combine): New inline function, with the contents
4242 of the old SXHASH_COMBINE.
4243 * profiler.c (hashfn_profiler): Use it, instead of having a
4244 special hash function containing a comparison that always yields 1.
4246 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4248 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4249 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4250 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4253 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4255 * image.c (xpm_make_color_table_h): Fix compiler error because
4256 make_hash_table changed.
4258 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4260 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4262 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4264 Use ad-hoc comparison function for the profiler's hash-tables.
4265 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4266 (make_log): Use them.
4267 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4268 call Fequal any more.

4277 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4278 (hash_lookup, hash_remove_from_table): Move assertion checking of
4279 hashfn result here. Check hash-equality before calling cmpfn.

4291 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4292 value of w32-scroll-lock-modifier is neither nil nor one of the
4293 known key modifiers. (Bug#12806)
4295 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4297 Shrink struct vectorlike_header to the only size field.
4298 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4300 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4301 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4302 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4303 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4304 information from the vector header. Adjust comment.

4319 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4320 (large_vectors): Change type to struct large_vector.
4321 (allocate_vector_from_block): Simplify.
4322 (PSEUDOVECTOR_NBYTES): Replace with...
4323 (vector_nbytes): ...new function. Adjust users.

4325 (allocate_vectorlike): Likewise.
4326 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4327 Add easserts. Adjust XSETPVECTYPESIZE usage.
4328 (allocate_buffer): Use BUFFER_PVEC_INIT.
4329 (live_vector_p): Adjust to match large vector.
4330 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4331 * buffer.h (struct buffer): Add next member.
4332 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4334 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4340 (xvecsize): New command.
4342 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4344 * keyboard.c (event_to_kboard): Do not dereference
4345 frame_or_window field of SELECTION_REQUEST_EVENT
4346 and SELECTION_CLEAR_EVENT events (Bug#12814).
4347 * xterm.h (struct selection_input_event): Adjust comment.
4349 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4351 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4352 such as Scroll Lock, if the respective keys are treated as
4353 function keys, not as modifiers. This avoids destroying non-ASCII
4354 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4356 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4358 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4360 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4362 Restore some duplicate definitions (Bug#12814).
4363 This undoes part of the 2012-11-03 changes. Some people build
4364 with plain -g rather than with -g3, and they need the duplicate
4365 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4366 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4367 Define as macros, as well as as enums or as constants.
4369 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4371 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4372 to keypad keys (Bug#12816).
4374 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4376 Minor adjustments of recently-changed frame functions.
4377 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4378 known to be a frame (we're in the FRAMEP branch).
4379 * lisp.h (Qframep): Remove decl. frame.h declares this.
4380 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4381 since they're meant for Lisp fixnum values.
4383 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4385 * window.c (Fwindow_combination_limit): Revert to the only
4386 required argument and adjust docstring as suggested in
4387 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4388 by Martin Rudalics <rudalics@gmx.at>.
4390 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4392 Widely used frame validity and checking functions.
4393 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4394 * frame.c (decode_live_frame, decode_any_frame): New functions.
4395 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4396 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4397 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4398 (Fframe_pointer_visible_p): Use decode_any_frame.

4400 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4401 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4402 (Fframe_focus): Likewise. Allow zero number of arguments.
4404 (frame_buffer_list, frame_buffer_predicate): Remove.
4405 * lisp.h (frame_buffer_predicate): Remove prototype.
4406 * buffer.c (Fother_buffer): Use decode_any_frame.
4407 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4408 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4409 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4410 (Fclose_font, Ffont_info): Use decode_live_frame.
4411 * fontset.c (check_fontset_name): Likewise.
4412 * terminal.c (Fframe_terminal): Likewise.
4413 * w32fns.c (check_x_frame): Likewise.
4414 * window.c (Fminibuffer_window, Fwindow_at)
4415 (Fcurrent_window_configuration): Likewise.
4416 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4417 Likewise. Allow zero number of arguments. Adjust docstring.
4418 * dispnew.c (Fredraw_frame): Likewise.
4419 * xfaces.c (frame_or_selected_frame): Remove.
4420 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4421 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4422 (Fframe_face_alist): Use decode_live_frame.
4423 * xfns.c (check_x_frame): Likewise.
4425 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4427 * window.c (quad): New function.
4428 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4429 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4430 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4431 (Fwindow_line_height): Use it.
4432 (Fwindow_fringes): Use list3.
4433 (Fwindow_scroll_bars): Use list4.
4434 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4435 (Fwindow_combination_limit): Allow zero number of arguments.
4437 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4439 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4441 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4442 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4443 file descriptor 2 for standard error. (Bug#12805)
4445 2012-11-05 Chong Yidong <cyd@gnu.org>
4447 * process.c (wait_reading_process_output): Revert previous change.
4449 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4451 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4452 This removes code that has been obsolete since around 1990.
4453 * callproc.c (Fcall_process):
4455 * process.c (create_process):
4456 * term.c (dissociate_if_controlling_tty):
4457 Assume setsid exists.
4458 * callproc.c (child_setup): Assume setpgid exists and behaves as
4459 per POSIX.1-1988 or later.
4460 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4461 * emacs.c (shut_down_emacs):
4462 * sysdep.c (sys_suspend, init_foreground_group):
4463 Assume getpgrp behaves as per POSIX.1-1998 or later.
4464 * msdos.c (setpgrp): Remove.
4465 (tcgetpgrp, setpgid, setsid): New functions.
4466 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4467 * term.c (no_controlling_tty): Remove; unused.
4468 * w32proc.c (setpgrp): Remove.
4469 (setsid, tcgetpgrp): New functions.
4471 Simplify by assuming __fpending.
4472 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4473 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4474 Do not assume that __fpending's result fits in int.
4476 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4478 Remove EMACS_OUTQSIZE+sleep hack.
4479 * dispnew.c (update_frame_1): Remove hack for terminals slower
4480 than 2400 bps, which throttled Emacs by having it sleep.
4481 This code hasn't worked since at least 2007, when the multi-tty stuff
4482 was added, and anyway those old terminals are long dead.
4483 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4484 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4486 Fix data-loss with --version (Bug#9574).
4487 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4488 as we can't assume that emacs_strerror is initialized, and strerror
4489 is good enough here.
4490 (main): Invoke atexit earlier, to catch earlier instances of
4491 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4493 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4495 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4496 (keyDown): Remap keypad keys to X11 virtual key codes.
4498 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4500 Fix data-loss with --batch (Bug#9574).
4501 * emacs.c: Include <close-stream.h>.
4502 (close_output_streams): New function.
4503 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4504 and handles errors appropriately.
4505 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4508 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4509 The symptom is a diagnostic "GLib-WARNING **: In call to
4510 g_spawn_sync(), exit status of a child process was requested but
4511 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4512 waitpid(), so exit status can't be returned." The diagnostic
4513 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4514 The real bug is a race condition between Emacs and glib: Emacs
4515 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4516 so that glib can't find it. Work around the bug by invoking
4517 waitpid only on subprocesses that Emacs itself creates.
4518 * process.c (create_process, record_child_status_change):
4519 Don't use special value -1 in pid field, as the caller now must
4520 know the pid rather than having the callee infer it.
4521 The inference was sometimes incorrect anyway, due to another race.
4522 (create_process): Set new 'alive' member if child is created.
4523 (process_status_retrieved): New function.
4524 (record_child_status_change): Use it.
4525 Accept negative 1st argument, which means to wait for the
4526 processes that Emacs already knows about. Move special-case code
4527 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4528 processes that have already been waited for, by testing and
4529 clearing new 'alive' member.
4530 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4531 now does this internally.
4532 (handle_child_signal): Let record_child_status_change do all
4533 the work, since we do not want to reap all exited child processes,
4534 only the child processes that Emacs itself created.
4535 * process.h (Lisp_Process): New boolean member 'alive'.
4537 Omit duplicate definitions no longer needed with gcc -g3.
4538 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4539 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4540 Define only as macros. There's no longer any need to also define
4541 these symbols as enums or as constants, since we now assume
4542 gcc -g3 when debugging.
4544 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4546 * lisp.mk: Adjust comments to the fact that term/internal is now
4547 loaded from loadup.el.
4549 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4550 (msdos_fatal_signal): New function.
4551 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4554 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4555 for GCC versions before 4.
4556 (emacs_raise): Define to call msdos_fatal_signal.
4558 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4559 iterator when starting in the middle of a display or overlay
4562 2012-11-03 Chong Yidong <cyd@gnu.org>
4564 * process.c (wait_reading_process_output): Clean up the last
4567 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4569 * process.c (wait_reading_process_output): Avoid a race condition
4570 with SIGIO delivery (Bug#11536).
4572 2012-11-03 Chong Yidong <cyd@gnu.org>
4574 * buffer.c (cursor_type): Untabify docstring.
4576 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4578 * frame.h (struct frame): Drop can_have_scroll_bars member
4579 which is meaningless for a long time. Adjust comments.
4580 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4581 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4583 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4585 * window.c (decode_next_window_args): Update window arg after
4586 calling decode_live_window and so fix crash reported at
4587 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4588 by Juanma Barranquero <lekktu@gmail.com>.
4589 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4590 * font.c (Ffont_at): Likewise.
4592 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4594 * widget.c (resize_cb): New function.
4595 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4596 (EmacsFrameResize): Check if all is up to date before changing frame
4599 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4601 Implement backtrace output for fatal errors on MS-Windows.
4602 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4603 (BACKTRACE_LIMIT_MAX): New macro.
4604 (w32_backtrace): New function.
4605 (emacs_abort): Use w32_backtrace when the user chooses not to
4606 attach a debugger. Update the text of the abort dialog.
4608 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4610 Window-related stuff cleanup here and there.
4611 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4612 Use decode_any_window.
4613 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4614 * xdisp.c (Fformat_mode_line): Likewise.
4615 * font.c (Ffont_at): Use decode_live_window.
4616 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4617 * window.c (decode_next_window_args): Likewise.
4618 (decode_any_window): Remove static.
4619 * window.h (decode_any_window): Add prototype.
4620 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4621 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4624 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4626 Remove pad from struct input_event.
4627 * termhooks.h (struct input_event): Remove padding field.
4629 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4630 member is never cons for a long time. Adjust comment.
4631 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4632 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4633 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4634 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4636 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4638 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4640 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4642 Fix crash when using Emacs as commit editor for git (Bug#12697).
4643 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4644 and it is configured in conf_post.h.
4645 (Fcall_process): Don't invoke both setsid and setpgid; the former
4646 is enough, if it exists.
4647 * callproc.c (Fcall_process, child_setup):
4648 * process.c (create_process): Use setpgid.
4649 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4651 * dispnew.c (init_display): Initialize the foreground group
4652 if we are running a tty display.
4653 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4654 * lisp.h (init_foreground_group): New decl.
4655 * sysdep.c (inherited_pgroup): New static var.
4656 (init_foreground_group, tcsetpgrp_without_stopping)
4657 (narrow_foreground_group, widen_foreground_group): New functions.
4658 (init_sys_modes): Narrow foreground group.
4659 (reset_sys_modes): Widen foreground group.
4661 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4663 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4665 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4667 * minibuf.c (read_minibuf): Restore current buffer since
4668 choose_minibuf_frame calling Fset_frame_selected_window may
4669 change it (Bug#12766).
4671 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4673 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4675 2012-10-30 Kenichi Handa <handa@gnu.org>
4677 * font.c (Ffont_at): If WINDOW is specified and it is not
4678 displaying the current buffer, signal an error.
4680 2012-10-29 Daniel Colascione <dancol@dancol.org>
4682 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4683 In preparation for fixing bug#12739, move these functions from
4686 * coding.h, coding.c: ... to here, and compile them only when
4687 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4688 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4690 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4692 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4693 (timer_loop, getitimer, setitimer): Use it instead of
4694 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4696 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4699 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4701 * nsterm.m (NO_APPDEFINED_DATA): New define.
4702 (last_appdefined_event_data): New variable
4703 (last_appdefined_event): Remove.
4704 (ns_select): Initialize t from last_appdefined_event_data instead
4705 of [last_appdefined_event data1].
4706 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4707 remove last_appdefined_event (Bug#12698).
4709 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4711 * frame.c (x_set_font): Catch internal error.
4713 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4715 Avoid overflow in w32 implementation of interval timers.
4716 When possible, for ITIMER_PROF count only times the main thread
4718 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4719 'volatile ULONGLONG' types. All the other data which was
4720 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4721 (GetThreadTimes_Proc): New typedef.
4722 (w32_get_timer_time): New function, returns a suitable time value
4724 (timer_loop): Enter critical section when accessing ULONGLONG
4725 values of the itimer_data struct, as these accesses are no longer
4726 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4727 Remove unused variable.
4728 (init_timers): Initialize s_pfn_Get_Thread_Times.
4729 (start_timer_thread): Don't assign itimer->caller_thread here.
4730 (getitimer): Assign itimer->caller_thread here.
4731 (setitimer): Always call getitimer to get the value of ticks_now.
4732 (sys_spawnve): Avoid compiler warning about format mismatch.
4734 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4736 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4737 mouse movement events if the menu bar is active. This avoids
4738 producing a busy "hour-glass" cursor by Windows if the mouse
4739 pointer is positioned over a tooltip shown for some menu item.
4741 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4743 Don't assume process IDs fit in int.
4744 * emacs.c (shut_down_emacs) [!DOS_NT]:
4745 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4746 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4747 Use pid_t, not int, to store process IDs, as 'int'
4748 is not wide enough on a few platforms (e.g., AIX and IRIX).
4750 2012-10-23 Kenichi Handa <handa@gnu.org>
4752 The following change is to make face-font-rescale-alist work
4753 correctly for non-ASCII fonts.
4755 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4756 (font_open_for_lface): Handle Vface_font_rescale_alist.
4758 2012-10-23 Chong Yidong <cyd@gnu.org>
4760 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4762 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4766 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4768 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4771 2012-10-21 Glenn Morris <rgm@gnu.org>
4773 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4775 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4777 Port to OpenBSD 5.1.
4778 * frame.c (Fmouse_position, Fmouse_pixel_position):
4779 * xdisp.c (produce_stretch_glyph):
4780 Declare local vars only when they're needed.
4781 This is clearer and avoids a warning on OpenBSD about unused vars.
4782 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4783 This is safer, and avoids OpenBSD warnings about unused vars.
4784 * keyboard.c (record_menu_key): Remove unnecessary decl.
4785 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4786 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4787 as our definition clashes with OpenBSD's.
4788 * xfaces.c (load_face_colors, check_lface_attrs)
4789 (get_lface_attributes_no_remap, get_lface_attributes)
4790 (lface_fully_specified_p, x_supports_face_attributes_p)
4791 (tty_supports_face_attributes_p, face_fontset, realize_face)
4792 (realize_x_face, realize_tty_face):
4793 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4794 merely Lisp_Object *. This is more informative and avoids
4795 a warning on OpenBSD about accessing beyond an object's size.
4797 2012-10-20 Chong Yidong <cyd@gnu.org>
4799 * lread.c (Fload): Doc fix (Bug#12592).

4803 * font.c (Ffont_at): Fix previous change.
4805 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4807 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4808 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

4825 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4826 (staticpro): If we run out of staticpro slots, die with an
4827 informative error instead of just calling emacs_abort.
4829 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4831 Fix two flaws reported by Dmitry Antipov.

5085 Use unsigned for counter where wraparound-on-overflow is desired,
5086 since unsigned is guaranteed to have that behavior and signed is not.
5087 (read_char): Use ptrdiff_t for string length.
5088 (get_input_pending): Remove first argument, since it was always
5089 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5090 and behave as if it had that value. Return new value of
5091 input_pending. All callers changed.
5092 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5093 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5095 * keymap.c (push_key_description): Omit last arg, which was always 1.
5096 All callers changed.
5098 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

5107 * alloc.c (mark_object): Use meaningful PVEC_NORMAL_VECTOR.
5108 * lisp.h (enum pvec_type): Adjust comments and omit explicit
5109 initializer for PVEC_NORMAL_VECTOR.
5111 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5113 Clean out old termopts cruft.
5114 * termopts.h (flow_control, meta_key): Remove unused decls.
5115 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5116 Don't include termopts.h.
5118 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5120 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5122 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5124 * commands.h (immediate_quit): Remove duplicate decl.
5126 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5128 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5130 (nsfont_open): Remove setting of Vfonts_in_cache.
5131 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5133 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5135 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5136 match what GetLastError returns. Explain why the function is
5139 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5140 'is_tooltip_frame', to avoid confusion with its global namesake.
5142 2012-10-08 Daniel Colascione <dancol@dancol.org>
5144 * xdisp.c (start_hourglass): Call w32_note_current_window when
5145 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5146 build that caused Emacs to display the hourglass cursor forever.
5148 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5149 which is broken under remote desktop, calculate the number of
5150 colors available for a display based on the display's number of
5151 planes and number of bits per pixel per plane. (bug#10397).
5153 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5155 * nsfont.m (Vfonts_in_cache): New variable.
5156 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5157 are used. Add cached fonts to Vfonts_in_cache.
5158 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5160 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5162 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5164 (FONT_H): Define after FRAME_H.
5165 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5166 Update dependencies.
5168 * w32term.c: Remove leftover declaration of keyboard_codepage.
5170 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5172 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5173 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5174 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5175 (GLOBAL_SOURCES): Add cygw32.c.
5176 ($(BLD)/unexw32.$(O)):
5178 ($(BLD)/w32console.$(O)):
5179 ($(BLD)/w32fns.$(O)):
5180 ($(BLD)/w32heap.$(O)):
5181 ($(BLD)/w32menu.$(O)):
5182 ($(BLD)/w32proc.$(O)): Add w32common.h.
5184 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5186 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5188 2012-10-08 Daniel Colascione <dancol@dancol.org>
5190 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5191 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5192 accidental message numbering hole. Change other messages to
5195 * w32select.h (HAVE_W32SELECT): Remove.
5197 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5198 w32common.h instead of w32heap.h.
5200 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5201 (get_allocation_unit, get_processor_type, get_w32_major_version)
5202 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5203 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5204 (OS_NT, os_subtype, cache_system_info): Move declarations to
5207 * w32heap.c: Include w32common.h.
5208 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5209 (w32_minor_version, w32_build_number, w32_subtype):
5210 Remove duplicate definitions.
5212 * w32fns.c: Include w32common.h; include w32heap.h only in
5215 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5216 Use `report_file_error' instead of `error' in order to better
5217 inform users of what went wrong. Increase NTGUI_UNICODE file
5218 dialog box file name length to 32k, the maximum allowed by the NT
5221 * w32common.h: New file.
5222 (ROUND_UP, ROUND_DOWN, get_page_size)
5223 (get_allocation_unit, get_processor_type, get_w32_major_version)
5224 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5225 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5226 (OS_NT, os_subtype, cache_system_info): Move here.
5228 * unexw32.c, unexcw.c: Include w32common.h.
5230 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5231 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5232 to call syms_of_w32select.
5234 * cygw32.h: Remove obsolete EXFUN declarations.
5236 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5238 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5239 of w32inevt.o from SOME_MACHINE_OBJECTS.
5241 2012-10-08 Daniel Colascione <dancol@dancol.org>
5243 * image.c: Permanent fix for JPEG compilation issue --- limit
5244 jpeglib `boolean' redefinition to Cygwin builds.
5246 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5248 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5250 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5253 2012-10-08 Daniel Colascione <dancol@dancol.org>
5255 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5256 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5257 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5258 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5259 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5260 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5261 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5262 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5263 now a supported configuration.
5265 * Makefile.in: consolidate image variables into LIBIMAGE; add
5266 W32_OBJ and W32_LIBS. Compile new files.
5269 (_DebPrint) declare tracing facility for W32 debugging. We need
5270 to unify tracing later.
5272 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5273 unconditional use of W32 Unicode functions. Cygwin runs only on
5274 100% Unicode operating systems.
5276 * cygw32.c: New file. Define Cygwin-specific facilities.
5277 (Fcygwin_convert_path_to_windows)
5278 (Fcygwin_convert_path_from_windows): New user functions for
5279 accessing Cygwin path-munging routines.
5281 * cygw32.h: New file.
5282 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5283 UTF-16LE strings temporarily inside non-Lisp-visible string
5286 (w32_strerror): Just what it says on the tin.
5288 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5289 also run for Cygwin; both systems have the same problem with using
5290 GUI facilities in a forked child. Also call syms_of_cygw32,
5291 syms_of_w32select in correct places.
5293 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5294 needs fork-then-exec for daemon launching.
5296 * font.h: Include frame.h.
5298 * image.c: Use the image library cache machinery only when we're
5299 compiling for native WINDOWSNT; Cygwin can use shared libraries
5300 like any other Unixlike system.
5302 * keyboard.c: Clarify a comment regarding the input loop.
5304 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5305 functions directly instead of trying to detect at runtime that our
5306 host operating system supports them. We make this change for two
5307 reasons: Cygwin lacks support for the multibyte character
5308 conversion functions used by the legacy menu code, and Cygwin
5309 never needs to rely on non-Unicode APIs.
5311 * unexw32.c (hinst): Declare extern.
5313 * w32.c: Change header order;
5314 (w32_strerror): Move to w32fns.c because we need it for
5315 non-WINDOWSNT builds.
5317 * w32.h: Add #error macro to make sure we don't include w32.h for
5318 Cygwin builds. Remove w32select declarations.
5320 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5321 w32fns.c. w32console.c is WINDOWSNT-only.
5323 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5324 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5326 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5327 (w32_major_version, w32_minor_version, w32_build_number)
5328 (os_subtype, sound_type): Define here
5329 (w32_defined_color): Make color parameter const for consistency
5330 with other _defined_color functions.
5331 (w32_createwindow): Unconditionally call w32_init_class instead of
5332 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5333 through the code is complex and unnecessary because class
5334 registration is practically free.
5335 (w32_name_of_message): New EMACSDEBUG-only function.
5336 (Fset_message_beep): Move here
5337 (Fx_open_connection): Require that the display name for Windows be
5338 "w32" for consistency, emacsclient disambiguation, and maybe, one
5339 day, multi-window-system support.
5340 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5341 Cygwin files for W32 GUI facilities, since these clearly don't
5342 expect Cygwin names.
5343 (_DebPrint): Define.
5344 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5345 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5346 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5347 (w32_last_error): Remove.
5349 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5351 * w32heap.c (syspage_mask): Declare here.
5352 (cache_system_info): Remove.
5354 * w32inevt.c (faked_key): Define globally, not statically.
5355 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5356 (w32_console_toggle_lock_key): Move to w32fns.c.
5358 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5360 * w32proc.c (_DebPrint): Move to w32fns.c.
5361 * w32select.c: Include string.h, stdio.h for Cygwin.
5362 * w32select.h: New File.
5364 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5366 (w32_message_fd): New variable. Under Cygwin, holds the file
5367 descriptor the system used to tell us about pending thread
5370 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5371 that prevented compilation under non-WINDOWSNT systems.
5373 (w32_initialize): Open /dev/windows and assign it to
5374 w32_message_fd. Provide w32 feature.
5376 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5377 (WM_EMACS_INPUT_READY): add.
5378 (prepend_msg, w32_message_fd): Declare globally.
5381 (keyboard_handle): Use only when WINDOWSNT.
5382 (notify_msg_ready): New function. Posts a message to the main
5383 thread's message queue under CYGWIN, which wakes up the main
5384 thread from select(2) by making the /dev/windows file descriptor
5385 ready. Under WINDOWSNT, it sets an event the same way the old
5388 (post, prepend_msg): Actually call notify_msg_ready instead of
5389 setting the input event directly.
5391 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5393 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5394 but it still has blocs in it, don't return it to the system,
5395 instead of aborting. (Bug#12402)
5397 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5399 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5401 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5402 MAC_OS_X_VERSION_10_6.
5403 (syms_of_nsterm): Remove comment about Panther and above for
5405 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5406 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5407 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5409 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5410 MAC_OS_X_VERSION_10_4.
5412 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5413 MAC_OS_X_VERSION_10_2.
5415 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5417 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5418 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5420 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5421 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5422 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5423 Remove ns_in_resize check.
5424 (ns_clear_frame_area): Remove resize handle code.
5426 * nsfns.m (ns_in_resize): Remove.
5427 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5428 Remove ns_in_resize check.
5430 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5432 Improve sys_siglist detection.
5433 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5434 defined as a macro, as is done in Solaris.
5435 (sys_siglist_entries): New macro.
5436 (save_strsignal): Use it.
5437 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5438 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5440 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5442 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5443 fullscreen/Fullscreen.
5445 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5446 tobar_height is new.
5448 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5449 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5450 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5451 (windowDidResize:): Check for correct window if old style fullscreen.
5452 Capitalize word in comment. Remove incorrect comment.
5453 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5454 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5455 error in drawing background.
5456 (toggleFullScreen:): Remove comment. Rearrange calls.
5457 Set toolbar values to zero, save old height in tobar_height.
5458 Restore tool bar height when leaving fullscreen.
5459 (canBecomeMainWindow): New function.
5461 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5463 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5465 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5467 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5469 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5470 that time stamps of directories could also be changed.
5471 Don't request the too broad GENERIC_WRITE, only the more restrictive
5472 FILE_WRITE_ATTRIBUTES access rights.
5474 * fileio.c (Fset_file_times): Special-case ignoring errors for
5475 directories only on MSDOS, not on MS-Windows.
5477 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5479 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5481 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5483 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5484 see whether CreateFile failed.
5486 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5488 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5489 to avoid similar races.
5490 * keyboard.c (pending_signals): Now bool, not int.
5492 Port timers to OpenBSD, plus check for timer failures.
5493 OpenBSD problem reported by Han Boetes.
5494 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5496 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5497 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5498 like OpenBSD, which has timer_settime but does not declare it.
5499 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5500 whether to use itimerspec-related primitives. All uses of
5501 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5503 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5505 * profiler.c (handle_profiler_signal): Fix a malloc race
5506 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5508 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5510 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5512 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5514 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5515 consistent with the change in return value of 'safe_strsignal'.
5517 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5519 Prefer plain 'static' to 'static inline' (Bug#12541).
5520 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5521 (bidi_set_sor_type, bidi_push_embedding_level)
5522 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5523 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5524 (bidi_cache_search, bidi_cache_ensure_space)
5525 (bidi_cache_iterator_state, bidi_cache_find)
5526 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5527 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5528 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5529 Now 'static', not 'static inline'.
5531 Count overruns when profiling; change units to ns.
5532 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5533 Give extra weight to samples after overruns, to attempt to count
5534 the time more accurately.
5535 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5536 the underlying primitives nominally do ns.
5537 (Fprofiler_cpu_start): Document the change. Mention that
5538 the sampling intervals are only approximate.
5540 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5542 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5544 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5545 case for the special 0 coding-system.
5547 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5548 (Fmake_overlay): Remove redundant tests.
5549 (fix_start_end_in_overlays): Remove redundant recentering.
5551 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5553 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5554 Update dependencies.
5556 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5558 Fix a malloc race condition involving strsignal.
5559 A signal can arrive in the middle of a malloc, and Emacs's signal
5560 handler can invoke strsignal, which can invoke malloc, which is
5561 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5562 Fix it by altering the signal handler so that it does not invoke
5564 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5565 * process.c (status_message): Use const pointer, in case strsignal
5566 is #defined to safe_strsignal.
5567 * sysdep.c (sys_siglist, init_signals): Always define and
5568 initialize a substitute sys_siglist if the system does not define
5569 one, even if HAVE_STRSIGNAL.
5570 (safe_strsignal): Rename from strsignal. Always define,
5571 using sys_siglist. Return a const pointer.
5572 * syssignal.h (safe_strsignal): New decl.
5573 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5575 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5577 * w32proc.c (timer_loop): Fix code that waits for timer
5578 expiration, to avoid high CPU usage.
5580 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5582 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5583 (sweep_weak_table): Remove redundant prototypes.
5585 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5587 * emacs.c: Move the inclusion of TERM_HEADER after including
5588 windows.h on WINDOWSNT. This avoids compilation problems with
5591 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5593 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5594 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5595 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5596 as the previous version used 'void *'.
5598 * ralloc.c (ROUNDUP): Fix last change.
5599 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5602 * w32proc.c <disable_itimers>: New static flag.
5603 (init_timers): Initialize it to zero, after creating the critical
5604 sections used by the timer threads.
5605 (term_timers): Set to 1 before deleting the critical sections.
5606 (getitimer, setitimer): If disable_itimers is non-zero, return an
5607 error indication without doing anything. Reported by Fabrice
5608 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5609 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5611 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5614 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5615 term_ntproc after all the other bookkeeping, to get timers working
5616 as long as possible.
5618 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5620 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5621 Suggested by Juri Linkov in
5622 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5624 Prefer plain 'static' to 'static inline' (Bug#12541).
5625 With static functions, modern compilers inline pretty well by
5626 themselves; advice from programmers often hurts as much as it helps.
5627 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5628 this change shrinks the text size of the Emacs executable by 1.1%
5629 without affecting CPU significantly in my benchmark.

5712 Revert the FOLLOW-SYMLINKS change for file-attributes.
5713 Doing it right would require several changes to Tramp, and there's
5714 not enough time to get that tested before the freeze today.
5715 * dired.c (directory_files_internal, Ffile_attributes):

5752 * w32.c (init_environment, get_emacs_configuration): Support AMD64
5754 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
5755 compatibility with x64.
5757 * vm-limit.c (lim_data): Now size_t.
5758 (check_memory_limits): Adjust prototypes of real_morecore and
5759 __morecore to receive argument of type ptrdiff_t. Use size_t for

5785 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
5786 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

5912 Profiler improvements: more-accurate timers, overflow checks.
5913 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5914 signal.h, setjmp.h. Include systime.h instead.
5915 (saturated_add): New function.

5923 (handle_profiler_signal): Rename from sigprof_handler_1,
5924 for consistency with other handlers. Do not check whether
5925 cpu_log is a hash-table if garbage collecting, since it
5926 doesn't matter in that case.

5928 for consistency with other handlers.
5929 (setup_cpu_timer): New function, with much of what used to be in
5930 Fprofiler_cpu_start. Check for out-of-range argument.
5931 Prefer timer_settime if available, and prefer
5932 thread cputime clocks, then process cputime clocks, then
5933 monotonic clocks, to the old realtime clock. Use make_timeval
5934 to round more-correctly when falling back to setitimer.
5935 (Fprofiler_cpu_start): Use it.
5936 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5937 Don't assume that passing NULL as the 2nd argument of setitimer
5938 is the same as passing a pointer to all-zero storage.
5939 Ignore SIGPROF afterwards.
5940 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5941 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5942 non-fatal signal handlers. Ignore SIGPROF on startup.
5943 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5944 in profiler.c, since sysdep.c now uses it.
5946 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

6002 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6003 Since this stuff is now private to charset.c, there's no need for
6004 a public macro and no need to inline by hand.

6035 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6037 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6039 Prefer POSIX timers if available.
6040 They avoid a race if the timer is too close to the current time.
6041 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6042 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6043 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6045 2012-09-25 Eli Zaretskii <eliz@gnu.org>

6050 STRING_CHAR_ADVANCE.
6052 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6054 Move Vlibrary_cache to emacs.c and reset before dumping.
6056 * lisp.h (reset_image_types): Declare.
6057 [WINDOWSNT] (Vlibrary_cache): Declare.
6059 * image.c (reset_image_types): New function.
6061 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

6068 * w32.h (Vlibrary_cache): Do not declare.
6070 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6072 * w32proc.c (sys_signal): Handle all signals defined by the
6073 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6074 handlers for signals supported by Windows. Don't override
6075 term_ntproc as the handler for SIGABRT.
6076 (sigaction): Rewrite to call sys_signal instead of duplicating its
6078 (sys_kill): Improve commentary.
6080 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6081 consistency with a signature of a signal handler. All callers
6083 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6084 install term_ntproc as a signal handler for SIGABRT, as that
6085 should be done by the dumped Emacs.
6087 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6089 * w32select.c (term_w32select): Protect against repeated
6090 invocation by setting clipboard_owner to NULL after calling

6094 and term_ntproc to their modified signatures.
6096 * character.c (char_string, string_char): Remove calls to
6097 MAYBE_UNIFY_CHAR. See the discussion starting at
6098 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6101 2012-09-25 Chong Yidong <cyd@gnu.org>
6103 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6105 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6107 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6108 when encountering an unknown bytecode.
6110 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6112 image.c, indent.c: Use bool for booleans.
6113 * dispextern.h (struct image_type): Members valid_p, load, init
6114 now return bool, not int. All uses changed.
6115 * image.c: Omit unnecessary static decls.
6116 (x_create_bitmap_mask, x_build_heuristic_mask):
6117 Return void, not int, since callers don't care about the return value.

6146 Use bool for booleans.
6148 2012-09-24 Chong Yidong <cyd@gnu.org>
6150 * chartab.c (Fset_char_table_default): Obsolete function removed.
6152 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6154 Move pid_t related decls out of lisp.h.
6155 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6156 (interruptible_wait_for_termination):
6157 Move these decls from lisp.h to syswait.h, since they use pid_t.
6158 Needed on FreeBSD; see Herbert J. Skuhra in
6159 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6160 * callproc.c: Include syswait.h.

6177 * nsmenu.m (ns_update_menubar):
6178 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6179 * xfns.c (Fx_show_tip) [USE_GTK]:
6180 Use bool for boolean.
6181 * gtkutil.c (xg_update_frame_menubar):
6182 * xmenu.c (update_frame_menubar):
6183 Return void, not int, since caller ignores return value.
6184 * gtkutil.c (xg_change_toolbar_position):
6187 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6189 * makefile.w32-in (BLOCKINPUT_H): Remove.

6206 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6208 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6209 fatal_error_backtrace.
6211 * w32proc.c (sys_kill): Undo last change: don't do anything when
6212 invoked to deliver SIGABRT to our own process. This is now
6213 handled by emacs_raise.
6215 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6217 * w32term.c (w32_read_socket): Remove leftover reference to
6218 interrupt_input_pending.
6220 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6222 Do not use SA_NODEFER.
6223 Problem reported by Dani Moncayo in
6224 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6226 * sysdep.c (emacs_abort): Do not reset signal handler.
6227 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6228 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6229 wanted even on POSIXish hosts, and it doesn't work on Windows.
6231 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6233 * xterm.c (x_term_init): Call fixup_locale before and after calling
6234 gtk_init (Bug#12392).
6236 2012-09-23 Chong Yidong <cyd@gnu.org>
6238 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6239 Vdynamic_library_alist.
6241 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6242 (Fgnutls_available_p): Caller changed.
6244 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6245 (Flibxml_parse_xml_region): Likewise.
6247 * dispextern.h (struct image_type): Remove arg from init function.
6249 * image.c (Finit_image_library, lookup_image_type)
6250 (define_image_type): Remove now-unneeded second arg.
6251 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6252 (init_tiff_functions, init_gif_functions, init_svg_functions):
6253 Arglist and w32_delayed_load calling convention changed.
6254 (gs_type): Remove init_gs_functions; there is no such function.
6255 (valid_image_p, make_image): Fix caller to lookup_image_type.
6257 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6259 Simplify and avoid signal-handling races (Bug#12471).
6261 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6262 Avoid recursive loop if there's a fatal error in the function itself.
6263 * atimer.c (pending_atimers):
6264 * blockinput.h: Don't include "atimer.h"; no longer needed.
6265 (interrupt_input_pending): Remove. All uses removed.
6266 pending_signals now counts both atimers and ordinary interrupts.
6267 This is less racy than having three separate pending-signal flags.
6268 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6270 Rename from their upper-case counterparts BLOCK_INPUT,
6271 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6272 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6273 This makes it easier to access volatile variables more accurately.
6274 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6275 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6276 that's more reliable if the code is buggy and sets
6277 interrupt_input_blocked to a negative value. All uses changed.
6278 * atimer.c (deliver_alarm_signal):
6279 Remove. No need to deliver this to the parent; any thread can
6280 handle this signal now. All uses replaced by underlying handler.
6281 * atimer.c (turn_on_atimers):
6282 * dispnew.c (handle_window_change_signal):
6283 * emacs.c (handle_danger_signal):
6284 * keyboard.c (kbd_buffer_get_event):
6285 Don't reestablish signal handler; not needed with sigaction.
6286 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6288 Rework to avoid unnecessary accesses to volatile variables.
6289 (UNBLOCK_INPUT_TO): Now a function.
6290 (totally_unblock_input, unblock_input): New decls.
6291 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6292 (init_data): Remove. Necessary stuff now done in init_signal.
6293 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6294 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6295 (fatal_error_code): Remove; no longer needed.
6296 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6297 it doesn't always backtrace. All uses changed. No need to reset
6298 signal to default, since sigaction and/or die does that for us now.
6299 Use emacs_raise (FOO), not kill (getpid (), FOO).
6300 (main): Check more-accurately whether we're dumping.
6301 Move fatal-error setup to sysdep.c
6302 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6303 * gtkutil.c (xg_get_file_name, xg_get_font):
6304 Remove no-longer-needed signal-mask manipulation.
6305 * keyboard.c, process.c (POLL_FOR_INPUT):
6306 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6307 * keyboard.c (read_avail_input): Remove.
6308 All uses replaced by gobble_input.
6309 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6310 (kbd_buffer_store_event_hold, gobble_input):
6311 (record_asynch_buffer_change) [USABLE_SIGIO]:
6312 (store_user_signal_events):
6313 No need to mess with signal mask.
6314 (gobble_input): If blocking input and there are terminals, simply
6315 set pending_signals to 1 and return. All hooks changed to not
6316 worry about whether input is blocked.
6317 (process_pending_signals): Clear pending_signals before processing
6318 them, in case a signal comes in while we're processing.
6319 By convention callers now test pending_signals before calling us.
6320 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6321 New functions, to support changes to blockinput.h.
6322 (handle_input_available_signal): Now extern.
6323 (reinvoke_input_signal): Remove. All uses replaced by
6325 (quit_count): Now volatile, since a signal handler uses it.
6326 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6327 All callers changed. Block SIGINT only if not already blocked.
6328 Clear sigmask reliably, even if Fsignal returns, which it can.
6329 Omit unnecessary accesses to volatile var.
6330 (quit_throw_to_read_char): No need to restore sigmask.
6331 * keyboard.c (gobble_input, handle_user_signal):
6332 * process.c (wait_reading_process_output):
6333 Call signal-handling code rather than killing ourselves.
6334 * lisp.h: Include <float.h>, for...
6335 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6336 (pending_signals): Now volatile.
6337 (syms_of_data): Now const if IEEE floating point.
6338 (handle_input_available_signal) [USABLE_SIGIO]:
6339 (terminate_due_to_signal, record_child_status_change): New decls.
6340 * process.c (create_process): Avoid disaster if memory is exhausted
6341 while we're processing a vfork, by tightening the critical section
6343 (send_process_frame, process_sent_to, handle_pipe_signal)
6344 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6346 (send_process): No need for setjmp/longjmp any more, since the
6347 SIGPIPE stuff is now gone. Instead, report an error if errno
6349 (record_child_status_change): Now extern. PID and W are now args.
6350 Return void, not bool. All callers changed.
6351 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6352 Remove. All uses removed. This bug should be fixed now in a
6354 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6355 and record the child status change directly. This avoids the
6356 need to futz with the signal mask.
6357 (process_fatal_action): Move here from emacs.c.
6358 (emacs_sigaction_flags): New function, containing
6359 much of what used to be in emacs_sigaction_init.
6360 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6361 caught by emacs, to make races less likely.
6362 (deliver_process_signal): Rename from handle_on_main_thread.
6364 (BACKTRACE_LIMIT_MAX): Now at top level.
6365 (thread_backtrace_buffer, threadback_backtrace_pointers):
6367 (deliver_thread_signal, deliver_fatal_thread_signal):
6368 New functions, for more-accurate delivery of thread-specific signals.
6369 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6370 (deliver_arith_signal): Handle in this thread, not
6371 in the main thread, since it's triggered by this thread.
6372 (maybe_fatal_sig): New function.
6373 (init_signals): New arg DUMPING so that we can be more accurate
6374 about whether we're dumping. Caller changed.
6375 Treat thread-specific signals differently from process-general signals.
6376 Block all signals while handling fatal error; that's safer.
6377 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6379 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6380 Ignore SIGPIPE unless batch.
6381 (emacs_backtrace): Output backtrace for the appropriate thread,
6382 which is not necessarily the main thread.
6383 * syssignal.h: Include <stdbool.h>.
6384 (emacs_raise): New macro.
6385 * xterm.c (x_connection_signal): Remove; no longer needed
6386 now that we use sigaction.
6387 (x_connection_closed): No need to mess with sigmask now.
6388 (x_initialize): No need to reset SIGPIPE handler here, since
6389 init_signals does this for us now.
6391 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6393 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6394 background rect may be larger (Bug#12245).
6396 2012-09-23 Chong Yidong <cyd@gnu.org>
6398 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6400 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6402 * .gdbinit: Just stop at fatal_error_backtrace.
6403 See Stefan Monnier's request in
6404 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6405 Remove no-longer-used query of system type.
6407 2012-09-22 Chong Yidong <cyd@gnu.org>
6409 * search.c (Freplace_match): Doc fix (Bug#12325).
6411 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6413 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6414 (Fline_end_position): Doc fix.
6416 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6418 2012-09-22 Chong Yidong <cyd@gnu.org>
6420 * dispextern.h (struct image_type): Add new slot, storing a type
6421 initialization function.
6423 * image.c (define_image_type): Call the image initializer function
6424 if it is defined. Arguments and return value changed.
6425 (valid_image_p, make_image): Callers changed.
6426 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6427 (gif_type, imagemagick_type, svg_type, gs_type):
6428 Add initialization functions.
6429 (Finit_image_library): Call lookup_image_type.
6430 (CHECK_LIB_AVAILABLE): Macro deleted.
6431 (lookup_image_type): Call define_image_type here, rather than via
6432 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6433 (syms_of_image): Move define_image_type calls for xbm_type and
6434 pbm_type to lookup_image_type.
6436 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6438 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6439 'idle_timers' from here ...
6440 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6441 lists, to avoid infloops when the timer does something stupid,
6442 like reinvoke itself with the same or smaller time-out.
6445 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6447 * window.c (Fsplit_window_internal): Handle only Qt value of
6448 Vwindow_combination_limit separately.
6449 (Qtemp_buffer_resize): New symbol.
6450 (Vwindow_combination_limit): New default value.
6453 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6455 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6456 the new overlay string. (Bug#10159)
6458 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6460 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6461 or that fprintf is async-signal-safe. POSIX doesn't require
6464 2012-09-22 Chong Yidong <cyd@gnu.org>
6466 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6469 2012-09-22 Kenichi Handa <handa@gnu.org>
6471 * composite.c (composition_reseat_it): Handle the case that a
6472 grapheme cluster is not covered by a single font (Bug#12352).
6474 2012-09-21 Chong Yidong <cyd@gnu.org>
6476 * image.c (define_image_type): Avoid adding duplicate types to
6477 image_types (Bug#12463). Suggested by Jörg Walter.
6479 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6481 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6482 (print_load_command_name): Add case LC_DATA_IN_CODE.
6483 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6485 2012-09-21 Glenn Morris <rgm@gnu.org>
6487 * eval.c (Frun_hook_with_args_until_success)
6488 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6490 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6492 * fileio.c (Ffile_selinux_context): Only call freecon when
6493 lgetfilecon succeeded.
6494 (Fset_file_selinux_context): Likewise. (Bug#12444)
6496 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6498 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6499 reordering, locate the cursor by calling set_cursor_from_row; if
6500 that fails, clear the desired glyph matrix before returning a
6501 failure indication to the caller. Fixes leaving garbled display
6502 when fast scrolling with a down-key. (Bug#12403)
6503 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6504 scrolling through multibyte text.
6506 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6508 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6509 calling mark_vectorlike since that's the one that marks the window.
6510 (mark_discard_killed_buffers): Mark the final cdr.
6511 * window.h (struct window): Move prev/next_buffers to the
6512 non-standard fields.
6513 * window.c (make_window): Initialize prev/next_buffers manually.
6515 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6517 Omit unused arg EXPECTED from socket hooks.
6518 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6519 * nsterm.m (ns_term_init):
6520 * termhooks.h (struct terminal.read_socket_hook):
6521 * w32inevt.c (w32_console_read_socket):
6522 * w32term.c (w32_read_socket):
6523 * xterm.c (XTread_socket):
6524 Omit unused arg EXPECTED. All callers changed.
6525 (store_user_signal_events): Return void, not int, since callers no
6526 longer care about the return value. All uses changed.
6528 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6530 * w32gui.h (XParseGeometry): Do not declare.
6532 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6534 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6535 Ignore 'expected'. See Eli Zaretskii in
6536 <http://bugs.gnu.org/12471#8> (last line).
6538 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6539 (XParseGeometry): Now static. Substitute extremal values for
6540 values that are out of range.
6542 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6544 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6546 * nsfns.m (XParseGeometry): Remove.
6547 (Fx_create_frame): Call x_set_offset to correctly interpret
6548 top_pos in geometry.
6550 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6551 (Fx_parse_geometry): If there is a space in string, call
6552 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6554 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6556 * search.c (scan_buffer): Use character positions in calls to
6557 region_cache_forward and region_cache_backward, not byte
6558 positions. (Bug#12196)
6560 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6561 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6563 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6564 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6565 emacs_blocked_malloc, now deleted.
6567 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6569 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6570 The workaround was for improving performance on Solaris 2.4, but
6571 is getting in the way now. Emacs will still work if someone is
6572 still running Solaris 2.4 in a museum somewhere; Sun dropped
6573 support for Solaris 2.4 in 2003.
6574 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6575 * process.c (create_process) [HAVE_WORKING_VFORK]:
6576 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6577 since Emacs no longer uses vfork on that platform.
6579 2012-09-17 Glenn Morris <rgm@gnu.org>
6581 * emacs.c: Use COPYRIGHT.
6583 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6585 Remove configure's --without-sync-input option (Bug#12450).
6586 When auditing signal-handling in preparation for cleaning it up,
6587 I found that SYNC_INPUT has race conditions and would be a real
6588 pain to fix. Since it's an undocumented and deprecated
6589 configure-time option, now seems like a good time to remove it.
6590 Also see <http://bugs.gnu.org/11080#16>.
6591 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6592 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6593 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6594 (malloc_hysteresis):
6595 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6596 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6597 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6598 (dont_register_blocks, bytes_used_when_reconsidered)
6599 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6600 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6601 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6602 Remove. All uses removed.
6603 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6604 implementation, one that depends on whether the new macro
6605 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6607 * atimer.c (run_timers, handle_alarm_signal):
6608 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6609 (handle_async_input, process_pending_signals)
6610 (handle_input_available_signal, init_keyboard):
6611 * nsterm.m (ns_read_socket):
6612 * process.c (wait_reading_process_output):
6613 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6614 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6616 * xterm.c (XTread_socket):
6618 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6619 * eval.c (handling_signal): Remove. All uses removed.
6620 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6621 All uses replaced with the SYNC_INPUT version.
6622 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6624 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6627 * font.c (Ffont_shape_gstring): Remove unused local.
6629 2012-09-16 Glenn Morris <rgm@gnu.org>
6631 * Makefile.in (clean): No longer run nextstep's clean.
6633 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6635 (ns-app): Move here from ns.mk, and simplify.
6636 (clean): Simplify nextstep entry.
6637 * ns.mk: Remove file.
6639 2012-09-17 Kenichi Handa <handa@gnu.org>
6641 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6642 not covert the last few charactes.
6644 2012-09-16 Kenichi Handa <handa@gnu.org>
6646 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6647 here, but just check the validity of glyphs in the glyph-string.
6649 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6651 * window.c (Fwindow_parameter, Fset_window_parameter):
6652 Accept any window as argument (Bug#12452).
6654 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6656 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6657 to ns_term_init to avoid memory leak.
6659 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6660 explicit retain/release.
6661 (ns_term_init): Only allow one display. Initialize outerpool and
6664 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6666 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6667 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6668 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6669 the Microsoft problem in a different way, by altering ../nt/config.nt.
6671 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6686 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6687 by lisp.h. This completes removal of setjmp.h inclusion
6688 erroneously announced in the previous commit. (Bug#12446)
6690 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6693 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6694 not defined as a macro. The latter happens on MS-Windows.
6697 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6699 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6700 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6701 Some instances of '#include <setjmp.h>' removed, if the
6702 only reason for the instance was because "lisp.h" was included.
6703 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6704 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6705 and _longjmp with the new symbols. Emacs already uses _setjmp if
6706 available, so this change affects only POSIXish hosts that have
6707 sigsetjmp but not _setjmp, such as some versions of Solaris and
6708 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6709 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6710 (png_load_body) [HAVE_PNG]:
6711 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6712 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6713 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6714 since PNG requires jmp_buf. This is the only exception to the
6715 general rule that we now use sys_setjmp and sys_longjmp.
6716 This exception is OK since this code does not change the signal
6717 mask or longjmp out of a signal handler.
6719 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6721 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6722 Include "syssignal.h", for 'main_thread'.
6724 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6726 Avoid out-of-range marker position (Bug#12426).
6727 * insdel.c (replace_range, replace_range_2):
6728 Adjust markers before overlays, as suggested by comments.
6729 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6730 Remove redundant check before calling offset_intervals.
6732 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6734 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6735 current buffer (Bug#12387).
6737 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6739 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6741 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6743 Use a more backwards-compatible timer format (Bug#12430).
6744 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6745 vector element, not from the 4th, since PSECS is now at the end.
6746 (Fcurrent_idle_time): Doc fix.
6748 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6750 Function to mark objects and remove killed buffers at once.
6751 * alloc.c (discard_killed_buffers): Rename to ...
6752 (mark_discard_killed buffers) ... new name. Add marking
6753 of remaining objects. Fix comment. Adjust users.
6754 (mark_object): Do not touch frame buffer lists here.
6755 * frame.c (delete_frame): Reset frame buffer lists here.
6757 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6759 Better workaround for GNOME bug when --enable-gcc-warnings.
6760 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6761 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6762 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6764 Simplify SIGIO usage (Bug#12408).
6765 The code that dealt with SIGIO was crufty and confusing, e.g., it
6766 played tricks like "#undef SIGIO" but these tricks were not used
6767 consistently. Simplify mostly by not #undeffing standard symbols,
6768 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6769 or not as we please) rather than "defined SIGIO" (standard symbol
6770 that we probably shouldn't #undef).
6771 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6772 Modules that need it can include it.
6773 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6774 * dispextern.h (ignore_sigio): New decl.
6775 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6776 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6777 * emacs.c (shut_down_emacs):
6778 * keyboard.c (kbd_buffer_store_event_hold):
6779 Use ignore_sigio rather than invoking 'signal' directly.
6780 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6782 (FIONREAD, SIGIO): Do not #undef.
6783 (tty_read_avail_input): Use #error rather than a syntax error.
6784 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6785 for I_PIPE, used by SETUP_SLAVE_PTY.
6786 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6787 * sysdep.c (croak): Remove; no longer needed. This bit of
6788 temporary code, with Fred N. Fish's comment that it's temporary,
6789 has been in Emacs since at least 1992!
6790 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6791 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6792 * syssignal.h (croak): Remove decl.
6793 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6794 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6795 now that we're termios-only.
6796 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6797 * term.c (dissociate_if_controlling_tty): Use #error rather than
6800 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6801 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6802 to work around GNOME bug 683906.
6803 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6804 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6805 This works around GCC bug 54561.
6807 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6809 More fixes for 'volatile' and setjmp/longjmp.
6810 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6811 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6812 (png_load_body) [HAVE_PNG]:
6813 (jpeg_load_body) [HAVE_JPEG]:
6814 New function, with most of the old parent function's body.
6815 (png_load) [HAVE_PNG]:
6816 (jpeg_load) [HAVE_JPEG]:
6817 Invoke the new function, to avoid longjmp munging our locals.
6818 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6819 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6820 longjmp is passed 2, as the C standard doesn't guarantee this.
6821 Instead, store the failure code into mgr->failure_code.
6823 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6825 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6826 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6827 (syms_of_keyboard): Remove support for unread-command-char.
6829 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6831 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6832 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6833 violation. (Bug#12426)
6835 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6837 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6839 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6841 * eval.c: Add `inhibit-debugger'.
6842 (Qinhibit_debugger): New symbol.
6843 (call_debugger): Bind it instead of Qdebug_on_error.
6844 (maybe_call_debugger): Test Vinhibit_debugger.
6845 (syms_of_eval): Define inhibit-debugger.
6846 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6847 (syms_of_xdisp): Remove inhibit-debug-on-message.
6849 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6851 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6852 If a nonvolatile local variable is written before a _longjmp to
6853 the frame containing the variable, and is read after the _longjmp,
6854 the value read is indeterminate. Some local variables of type
6855 'struct handler' and 'struct catchtag' are used in this way, so
6856 mark each of their slots as volatile if the slot can be set before
6857 _longjmp and read afterwards.
6858 * lisp.h (struct handler): var and chosen_clause are now volatile.
6859 (struct catchtag): val, next, and pdlcount are now volatile.
6861 * bidi.c (bidi_push_it, bidi_pop_it):
6862 * fns.c (copy_hash_table):
6863 * image.c (define_image_type):
6864 * keyboard.c (kbd_buffer_store_event_hold):
6865 * process.c (Fprocess_send_eof):
6866 * xfaces.c (x_create_gc) [HAVE_NS]:
6867 * xgselect.c (xg_select):
6868 Prefer assignment to memcpy when either will do.
6870 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6871 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6872 time an item is removed. No need to mark this function 'inline';
6873 the compiler knows better than we do.
6875 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6877 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6878 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6879 to change_frame_size (Bug#12388).
6880 (windowDidResize:): Pass YES to updateFrameSize.
6882 * nsterm.h: Add delay parameter to updateFrameSize.
6884 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6886 Discard killed buffers from deleted window and frame objects.
6887 This reduces an amount of references to killed buffers and
6888 helps GC to reclaim them faster.
6889 * alloc.c (discard_killed_buffers): New function.
6890 (mark_object): Use it for deleted windows and frames.
6891 (mark_object): If symbol's value is set up for a killed buffer
6892 or deleted frame, restore its global binding.
6893 * data.c (swap_in_global_binding): Add GC notice.
6894 (swap_in_symval_forwarding): Use convenient set_blv_where.
6895 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6896 * window.h: ... to here.
6898 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6900 Convenient macro to check whether the buffer is live.
6901 * buffer.h (BUFFER_LIVE_P): New macro.
6902 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6903 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6905 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6907 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6908 composition cases (Bug#12364).
6910 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6911 overhang of succeeding glyphs overlapping box cursor.
6913 * w32term.c (x_draw_glyph_string): Likewise.
6915 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6917 Simplify, document, and port floating-point (Bug#12381).
6918 The porting part of this patch fixes bugs on non-IEEE platforms
6919 with frexp, ldexp, logb.
6920 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6922 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6923 support, by removing commented-out code and briefly listing the
6924 C89 functions excluded. The commented-out stuff was confusing
6925 maintenance, e.g., we thought we needed cbrt but it was commented out.
6926 (logb): Remove decl; no longer needed.
6927 (isfinite): New macro, if not already supplied.
6928 (isnan): Don't replace any existing macro.
6929 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6930 are present on all C89 platforms.
6931 (Ffrexp): Do not special-case zero, as frexp does the right thing
6933 (Flogb): Do not use logb, as it doesn't have the desired meaning
6934 on hosts that use non-base-2 floating point. Instead, stick with
6935 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6936 frexp, to avoid getting an unspecified result.
6938 * xdisp.c (Qinhibit_debug_on_message): Now static.
6940 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6942 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6943 NSBezierPath (Bug#12131).
6945 2012-09-10 Chong Yidong <cyd@gnu.org>
6947 * fns.c (Fdelq, Fdelete): Doc fix.
6949 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6951 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6952 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6954 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6956 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6957 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6960 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6962 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6963 left fringe if the window has a left margin. This avoids leaving
6964 traces of the cursor because its leftmost pixel is not drawn over.
6966 * dispnew.c (update_window_line): When the left margin area of a
6967 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6968 that screen line. (Bug#12277)
6970 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6972 Assume C89 or later for math functions (Bug#12381).
6973 This simplifies the code, and makes it a bit smaller and faster,
6974 and (most important) makes it easier to clean up signal handling
6975 since we can stop worring about floating-point exceptions in
6976 library code. That was a problem before C89, but the problem
6977 went away many years ago on all practical Emacs targets.
6978 * data.c, image.c, lread.c, print.c:
6979 Don't include <math.h>; no longer needed.
6980 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6981 might be autoconfigured, as that never happens.
6983 * doprnt.c (DBL_MAX_10_EXP):
6984 * print.c (DBL_DIG):
6985 Remove. C89 or later always defines these.
6986 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6987 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6988 (arith_error, domain_error, domain_error2):
6989 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6990 no longer needed -- we simply return what C returns. All uses removed.
6991 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6993 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6994 Remove. All uses expanded, as these macros are no longer used
6995 more than once and are now more trouble than they're worth.
6996 (Ftan): Use tan, not sin / cos.
6997 (Flogb): Assume C89 frexp.
6998 (fmod_float): Assume C89 fmod.
6999 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7000 (init_floatfns): Remove. All uses removed.
7002 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7004 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7005 compositeToPoint for OSX < 10.6 (Bug#12390).
7007 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7009 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7010 This produces more-accurate results.
7012 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7014 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7015 changes (Bug#12088).
7017 2012-09-08 Chong Yidong <cyd@gnu.org>
7019 * syntax.c (Fstring_to_syntax): Doc fix.
7021 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7023 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7024 in the internal border.
7025 (x_set_window_size): Remove static variables and their usage.
7026 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7027 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7028 Remove fringe/internal border adjustment (Bug#11052).
7029 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7030 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7031 (ns_fix_rect_ibw): Remove.
7032 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7033 (ns_dumpglyphs_box_or_relief): Ditto.
7034 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7036 (ns_dumpglyphs_image): Ditto.
7037 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7039 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7040 their usage. Add fringe_extended_p and its use as in other terms.
7041 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7042 scroll bar was removed.
7043 (updateFrameSize): New function.
7044 (windowDidResize): Move code to updateFrameSize and call it.
7046 * nsterm.h (EmacsView): Add updateFrameSize.
7048 2012-09-07 Chong Yidong <cyd@gnu.org>
7050 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7052 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7054 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7056 More signal-handler cleanup (Bug#12327).
7057 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7058 Problem introduced when merging patches. Noted by Eli Zaretskii in
7059 <http://bugs.gnu.org/12327#67>.
7060 * floatfns.c: Comment fix.
7061 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7062 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7063 and anyway the declaration is harmless even if SIGDANGER is not defined.
7064 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7065 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7066 source files not surprisingly expected syssignal.h to define, or
7067 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7068 Include <sys/ioctl.h>, for FIONREAD.
7069 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7070 This eliminates a problem whereby other files mysteriously had
7071 to include "syssignal.h" before including "systty.h" if they
7072 wanted to use "#ifdef SIGIO".
7074 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7076 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7078 * w32.c (sigemptyset): Empty the set.
7079 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7081 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7083 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7085 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7086 (mark_object): Likewise for frame objects.
7088 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7090 * syssignal.h (handle_on_main_thread): Always declare,
7091 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7092 This ports to platforms without HAVE_PTHREAD.
7094 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7096 Signal-handler cleanup (Bug#12327).
7097 Emacs's signal handlers were written in the old 4.2BSD style with
7098 sigblock and sigmask and so forth, and this led to some
7099 inefficiencies and confusion. Rewrite these to use
7100 pthread_sigmask etc. without copying signal sets around. Also,
7101 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7102 'signal', and instead use functions that do not attempt to take
7103 over the system name space. This patch causes Emacs's text
7104 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7105 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7106 Do not include <signal.h> or "syssignal.h", as these
7107 modules do not use signals.
7108 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7109 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7110 Do not include <signal.h>, as "syssignal.h" does that for us now.
7111 * atimer.c (sigmask_atimers): New function.
7112 (block_atimers, unblock_atimers): New functions,
7113 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7115 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7116 no longer needed here.
7117 * emacs.c (main): Inspect existing signal handler with sigaction,
7118 so that there's no need to block and unblock SIGHUP.
7119 * sysdep.c (struct save_signal): New member 'action', replacing
7120 old member 'handler'.
7121 (save_signal_handlers, restore_signal_handlers):
7122 Use sigaction instead of 'signal' to save and restore.
7123 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7124 New function. All users of 'signal' modified to use set_sighandler
7125 if they're writeonly, and to use sys_signal if they're read+write.
7126 (emacs_sigaction_init, forwarded_signal): New functions.
7127 (sys_signal): Remove. All uses replaced by calls to sigaction
7128 and emacs_sigaction_init, or by direct calls to 'signal'.
7129 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7130 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7131 all uses replaced by pthread_sigmask etc. calls.
7132 * syssignal.h: Include <signal.h>.
7133 (emacs_sigaction_init, forwarded_signal): New decls.
7134 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7135 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7136 (sigmask, sys_sigmask): Remove; no longer needed.
7137 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7138 (sigblock, sigunblock, sigfree):
7139 (sigsetmask) [!defined sigsetmask]:
7140 Remove. All uses replaced by pthread_sigmask.
7141 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7142 no longer need to be replaced, and its typical old uses
7143 are now done via emacs_sigaction_init and sigaction.
7144 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7145 (sys_sigdel): Remove; unused.
7146 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7148 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7150 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7151 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7153 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7155 Explicitly mark buffer_defaults and buffer_local_symbols.
7156 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7157 mark_local_symbols here.
7158 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7159 since special buffers aren't marked here any more.
7160 (allocate_buffer): Chain new buffer with all_buffers here...
7161 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7163 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7164 (syms_of_buffer): Remove staticpro of the above.
7165 (init_buffer_once): Set names for buffer_defaults and
7166 buffer_local_symbols.
7168 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7170 Use bool for booleans in font-related modules.
7171 * font.c (font_intern_prop, font_style_to_value)
7172 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7173 (generate_otf_features, font_check_otf_features, font_check_otf)
7174 (font_match_p, font_list_entities, font_at):
7175 * fontset.c (fontset_id_valid_p, reorder_font_vector
7176 (fontset_find_font, Fset_fontset_font)
7177 (face_suitable_for_char_p) [0]:
7178 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7179 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7180 (m17n_flt_initialized, ftfont_shape_by_flt):
7181 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7182 * nsfont.m (nsfont_draw):
7183 * w32font.c (w32font_draw):
7184 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7185 Use bool for booleans.
7186 * font.h: Adjust to above API changes.
7187 (struct font, struct font_driver, struct font_driver_list):
7188 Use bool for booleans.
7189 (struct font): Remove useless member encoding_type.
7191 * fontset.c, xftfont.c: Omit unnecessary static decls.
7193 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7195 * alloc.c (mark_object): Revert window marking code
7196 since it's unsafe for the Fset_window_configuration.
7198 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7200 Fix race conditions with signal handlers and errno (Bug#12327).
7201 Be more systematic about preserving errno whenever a signal
7202 handler returns, even if it's not in the main thread. Do this by
7203 renaming signal handlers to distinguish between signal delivery
7204 and signal handling. All uses changed.
7205 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7206 * data.c (deliver_arith_signal): Rename from arith_error.
7207 * dispnew.c (deliver_window_change_signal): Rename from
7208 window_change_signal.
7209 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7210 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7211 * keyboard.c (deliver_input_available_signal): Rename from
7212 input_available_signal.
7213 (deliver_user_signal): Rename from handle_user_signal.
7214 (deliver_interrupt_signal): Rename from interrupt_signal.
7215 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7216 (deliver_child_signal): Rename from sigchld_handler.
7217 * atimer.c (handle_alarm_signal):
7218 * data.c (handle_arith_signal):
7219 * dispnew.c (handle_window_change_signal):
7220 * emacs.c (handle_fatal_signal, handle_danger_signal):
7221 * keyboard.c (handle_input_available_signal):
7222 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7223 * process.c (handle_pipe_signal, handle_child_signal):
7224 New functions, with the actual signal-handling code taken from the
7225 original respective signal handlers, sans the sporadic attempts to
7226 preserve errno, since that's now done by handle_on_main_thread.
7227 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7228 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7229 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7231 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7232 Move initialization of main_thread to sysdep.c's init_signals.
7233 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7234 our usage, and simplifies the mainline code.
7235 (record_child_status_change): New static function, as a helper
7236 for handle_child_signal, and with most of the old child handler's
7238 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7239 (handle_child_signal): Use the above.
7240 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7241 Moved here from emacs.c.
7242 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7243 code moved here from emacs.c's main function.
7244 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7245 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7246 This lets callers save and restore errno properly.
7248 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7250 Remove redundant or unused things here and there.
7251 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7252 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7253 * editfns.c (Fcompare_buffer_substrings): Likewise.
7254 * frame.h (struct terminal, struct font_driver_list):
7255 Remove redundant declarations.
7256 * window.h (Qleft, Qright): Likewise.

7262 (mark_object): Likewise for windows and frames.
7264 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7266 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7267 buffer_defaults and buffer_local_symbols as valid objects.
7268 Return special value to denote them.
7270 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7272 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7273 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7274 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7275 (file_name_absolute_p, Fsubstitute_in_file_name):
7276 (check_executable, check_writable, Ffile_accessible_directory_p)

7278 (Finsert_file_contents, choose_write_coding_system)
7279 (Fwrite_region, build_annotations, a_write, e_write)
7281 * filelock.c (boot_time_initialized, get_boot_time)
7282 (get_boot_time_1, lock_file_1, within_one_second):
7283 * floatfns.c (in_float):
7284 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7285 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7286 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7287 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7288 * window.c (compare_window_configurations):
7289 Use bool for booleans.
7290 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7291 (Fdefault_file_modes): Now mode_t, not int, for modes.
7292 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7293 (internal_delete_file): Now returns void, not a (boolean) int,
7294 since nobody was looking at the return value.
7295 * lisp.h, window.h: Adjust to above API changes.
7297 * xdisp.c (set_message): Simplify and reindent last change.
7299 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7301 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7303 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7305 * eval.c (call_debugger): Make the function non-static so that we
7306 can call it from set_message.
7308 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7309 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7311 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7313 Give more-useful info on a fatal error (Bug#12328).
7314 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7315 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7316 of doing the work ourselves.
7317 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7318 do most of the work.
7319 (fatal_error_backtrace): New function, taken from the guts
7320 of the old fatal_error_signal, but with a new option to output
7322 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7323 info about the signal than just its number.
7324 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7325 * sysdep.c: Include <execinfo.h>
7326 (emacs_backtrace): New function, taken partly from the previous
7327 code of the 'die' function.
7328 (emacs_abort): Call fatal_error_backtrace rather than abort.
7330 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7332 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7333 eager (load-time) macro-expansion.
7334 * lisp.mk (lisp): Add macroexp.
7336 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7338 Simplify redefinition of 'abort' (Bug#12316).
7339 Do not try to redefine the 'abort' function. Instead, redo
7340 the code so that it calls 'emacs_abort' rather than 'abort'.
7341 This removes the need for the NO_ABORT configure-time macro
7342 and makes it easier to change the abort code to do a backtrace.
7343 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7344 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7345 Remove; sysdep.c's emacs_abort now takes its place.
7346 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7347 'abort' changed to use 'emacs_abort'.
7348 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7349 (abort) [!defined abort]: Rename to ...
7350 (emacs_abort): ... new name.
7351 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7352 the place of the old 'abort' in emacs.c.
7353 * w32.c, w32fns.c (abort): Do not #undef.
7354 * w32.c (emacs_abort): Rename from w32_abort.
7356 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7358 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7359 offsets[j].dv, since the y axis of the screen coordinates points
7360 down, while the y axis of the font definition coordinates points
7361 up. This fixes display of Arabic diacritics such as KASRA and
7362 KASRATAN. (Bug#11860)
7364 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7366 Be more systematic about _setjmp vs setjmp.
7367 * alloc.c (test_setjmp, mark_stack):
7368 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7369 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7370 (png_load, my_error_exit, jpeg_load):
7371 * process.c (send_process_trap, send_process):
7372 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7373 The underscored versions are up to 30x faster on some hosts.
7374 Formerly, the code used setjmp+longjmp sometimes and
7375 _setjmp+_longjmp at other times, with no particular reason to
7376 prefer setjmp+longjmp.
7378 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7380 Fix minor problem found by static checking.
7381 * buffer.c (Fdelete_all_overlays): Return nil.
7383 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7385 * buffer.c (Fdelete_all_overlays): New function.
7387 2012-09-03 Chong Yidong <cyd@gnu.org>
7389 * gtkutil.c: Add extern decl for Qxft.
7391 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7407 EXCLUDE_SUBRS_P. All callers changed.
7408 * dispextern.h, lisp.h: Reflect above API changes.
7409 * firstfile.c (dummy): Use the address of 'main', whose signature
7410 won't change, instead of the address of 'initialize', whose
7411 signature just changed from int to bool.
7412 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7413 * msdos.c (fatal_error_in_progress): ... from here.
7414 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7416 (redisplay_internal, unwind_redisplay): Simply clear
7417 REDISPLAYING_P when unwinding, instead of saving its previous,
7418 always-false value and then restoring it.
7420 Clean up some extern decls.
7421 Mostly, this hoists extern decls out of .c files and into .h files.
7422 That way, we're more likely to catch errors if the interfaces change.
7423 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7424 declare xg_mark_data.
7425 * dispextern.h (x_frame_parm_handlers):
7427 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

7443 * xfont.c (x_clear_errors):
7444 * xterm.c (x_frame_parm_handlers):
7445 Remove now-redundant extern decls.
7446 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7447 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7449 * xfaces.c: Remove unnecessary static decls.
7450 * xterm.c (updating_frame): Remove decl of nonexistent object.
7452 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7453 when building globals.h, as the objects that are not built on
7454 this host are not needed to compile C files on this host.
7456 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7458 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7506 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7508 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7509 more than one grapheme cluster passed to the shaper: compute the
7510 offset adjustment values separately for each cluster. (Bug#11860)
7512 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7513 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7514 about implicit conversions from integer to pointer.
7516 2012-09-01 Daniel Colascione <dancol@dancol.org>
7518 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7519 system used too early.
7521 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7523 Better seed support for (random).

7572 window system declarations.
7574 * frame.h: Move common functions here: set_frame_menubar,
7575 x_set_window_size, x_sync, x_get_focus_frame,
7576 x_set_mouse_position, x_set_mouse_pixel_position,
7577 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7601 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7603 Remove mark_ttys function and fix tty_display_info initialization.
7604 * lisp.h (mark_ttys): Remove prototype.
7605 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7606 to mark_ttys because all possible values of 'top_frame' slot are
7607 the frames which are reachable from Vframe_list.
7608 * term.c (mark_ttys): Remove.
7609 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7611 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

7638 * lread.c (init_lread): For out-of-tree builds, only add the
7639 source directory's site-lisp dir to the load-path if it exists,
7640 consistent with in-tree builds. (Bug#12302)
7642 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

7659 (timeout_handler:): Set timer_fired to YES.
7660 (runDialogAt:): Set timer_fired to NO.
7661 Handle click on close button as quit.
7663 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7664 Add window_closed and button_values. Add void as return value for
7665 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7666 Add process_dialog as new member.
7668 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7670 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

7773 Use bool for booleans.
7774 * dired.c (file_name_completion):
7775 * process.h (fd_callback):
7776 Omit int (actually boolean) argument. It wasn't being used.
7778 * composite.h, lisp.h: Reflect above API changes.
7780 * cmds.c, coding.c: Use bool for booleans.

7801 (Fset_coding_system_priority):
7802 * fileio.c (Finsert_file_contents):
7803 Use bool for booleans.
7804 * coding.h, lisp.h: Reflect above API changes.
7805 * coding.c: Remove unnecessary static function decls.
7806 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7807 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7808 not a boolean 'int', since callers never look at the return value.
7809 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7810 * coding.h (decoding_buffer_size, encoding_buffer_size)
7811 (emacs_mule_string_char): Remove unused extern decls.
7812 (struct iso_2022_spec, struct coding_system):
7813 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7814 (struct emacs_mule_spec): Remove unused field 'full_support'.
7815 All initializations removed.
7816 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7818 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7820 Fix spare memory change (Bug#12286).
7821 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7822 (valid_lisp_object_p): Likewise.
7824 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7826 * window.c (Fset_window_configuration): Record any window's old
7827 buffer if it's replaced (see Bug#8789). If the new current
7828 buffer doesn't appear in the selected window, go to its old
7831 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7833 Special MEM_TYPE_SPARE to denote reserved memory.
7834 * alloc.c (enum mem_type): New memory type.
7835 (refill_memory_reserve): Use new type for spare memory.
7836 This prevents live_cons_p and live_string_p from incorrect
7837 detection of uninitialized objects from spare memory as live.
7839 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7842 * Makefile.in (.PHONY): versioclean -> versionclean.
7844 Remove unused external symbols.
7845 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7846 * window.c (Qwindow_valid_p, decode_valid_window):
7847 Now static, not extern.
7848 * data.c (Qinterval): Remove; unused.
7849 (syms_of_data): Do not define 'interval'.
7850 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7851 * window.h (decode_valid_window):
7854 * character.c, charset.c, chartab.c: Use bool for booleans.

7864 (char_table_set_range, optimize_sub_char_table)
7865 (map_sub_char_table):
7866 Use bool for boolean.
7867 * character.c (str_to_unibyte): Omit last boolean argument; it was
7868 always 0. All callers changed.
7869 * character.h, charset.h: Adjust to match previous changes.
7870 * character.h (char_printable_p): Remove decl of nonexistent function.
7871 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7872 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7873 are all boolean, so make them single-bit bitfields.
7875 * lisp.h (ASET): Remove attempt to detect side effects.
7876 It was meant to be temporary and it often doesn't work,
7877 because when IDX has side effects the behavior of IDX==IDX
7878 is undefined. See Stefan Monnier in
7879 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7881 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7883 * lisp.h (functionp): New function (extracted from Ffunctionp).
7884 (FUNCTIONP): Use it.
7885 * eval.c (Ffunctionp): Use it.
7887 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7889 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7890 as that's faster and simpler than static storage. Don't bother
7891 with the g_main_context_query overhead if g_main_context_pending
7892 says no events are pending.
7893 (gfds, gfds_size): Remove these static vars.
7894 (xgselect_initialize): Remove; no longer needed.
7895 All uses and decls removed.
7897 * emacs.c (fatal_error_signal_hook): Remove.
7898 All uses removed. This leftover from old code was always 0.
7900 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7901 * casefiddle.c (casify_object, casify_region):
7902 * casetab.c (set_case_table):
7903 * category.c, category.h (word_boundary_p):
7904 * category.h (CHAR_HAS_CATEGORY):
7905 Use bool for booleans, instead of int.
7907 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7909 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7911 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7913 On assertion failure, print backtrace if available.
7914 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7915 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7916 * Makefile.in (LIB_EXECINFO): New macro.
7919 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7920 * bytecode.c (exec_byte_code):
7921 * callint.c (check_mark, Fcall_interactively):
7922 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7923 (getenv_internal, sync_process_alive, call_process_exited):
7924 * lisp.h (USE_SAFE_ALLOCA):
7925 Use bool for booleans, instead of int.
7926 * lisp.h, process.h: Adjust prototypes to match above changes.
7927 * callint.c (Fcall_interactively): Don't assume the mark's
7928 offset fits in 'int'.
7930 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7932 * buffer.c, buffer.h: Use bool for boolean.
7933 * buffer.c (reset_buffer_local_variables)
7934 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7935 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

7937 (overlay_touches_p, overlay_strings, Foverlay_put)
7938 (report_overlay_modification, call_overlay_mod_hooks):
7939 (mmap_enlarge, mmap_set_vars):
7940 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7941 Use bool for booleans, instead of int.
7942 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7943 since the 1-or-0 return value is always ignored anyway.
7944 (mmap_initialized_p):
7945 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7946 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7948 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7950 * bidi.c: Use bool for boolean.
7951 This is a bit more readable, and makes the text segment of bidi.o
7952 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7953 Presumably it's faster too.
7954 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7956 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7957 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7958 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7959 (bidi_explicit_dir_char, bidi_level_of_next_char)
7960 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7961 Use bool for booleans, instead of int.
7962 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7963 (bidi_unshelve_cache): Adjust decls to match code.
7965 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7967 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7970 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7972 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7973 * atimer.h: Include <stdbool.h>.
7975 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7977 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7978 compile time tests instead of run time tests on systems that do
7980 (FRAME_MAC_P): Remove leftover from deleted code.
7981 * frame.c (syms_of_frame): Remove leftover from deleted code.
7983 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7985 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7987 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7989 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7990 Otherwise, the compiler complains about (A?B:C) where B is void
7991 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7992 (fontset_add): Return void, for FONTSET_ADD.
7994 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7996 * alloc.c: Use bool for booleans.
7997 (gc_in_progress, abort_on_gc)
7998 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7999 (dont_register_blocks) [GC_MALLOC_CHECK]:
8000 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8001 (check_string_bytes, make_specified_string, memory_full)
8002 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8003 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8004 (mark_stack, valid_pointer_p, make_pure_string)
8005 (Fgarbage_collect, survives_gc_p, gc_sweep):
8006 Use bool for booleans, instead of int.
8007 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8008 Remove unused local.
8009 * alloc.c (PURE_POINTER_P):
8010 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8011 * editfns.c (Fformat):
8012 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8014 * fns.c (sweep_weak_table):
8015 * lisp.h (suppress_checking, push_message, survives_gc_p)
8016 (make_pure_string, gc_in_progress, abort_on_gc):
8017 * lread.c (readchar, read1):
8018 * print.c (Fprin1_to_string):
8019 * xdisp.c (push_message):
8020 Use bool for booleans affected directly or indirectly by
8023 Make recently-introduced setters macros.
8024 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8025 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8026 (set_fontset_default, set_fontset_fallback): Rename from their
8027 upper-case counterparts, and make them functions rather than macros.
8028 This is more consistent with the other recently-introduced setters.
8029 These don't need to be inline, since they're local.
8031 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8033 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8034 the loop (Bug#12247).
8036 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8038 * lisp.h (vcopy): Use memcpy rather than our own loop.
8039 This fixes a performance regression introduced by the recent
8040 addition of vcopy. This means 'vcopy' will need to be modified
8041 for a copying collector, but that's OK. Also, tighten the
8042 checking in the assertion.
8044 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8046 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8047 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8048 non-base glyph for the width of the base character, according to
8049 what x_draw_composite_glyph_string_foreground expects.
8050 Generate WADJUST value according to composition_gstring_width's
8051 expectations, to produce correct width of the composed character.
8052 Reverse the sign of the DU offset produced by ScriptPlace.
8054 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8056 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8058 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8060 Avoid direct writes to contents member of struct Lisp_Vector.
8061 * lisp.h (vcopy): New function to copy data into vector.
8062 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8063 * fns.c (Ffillarray): Use ASET.
8064 * keyboard.c (timer_check_2): Use AREF and ASET.
8065 (append_tool_bar_item, Frecent_keys): Use vcopy.
8066 * lread.c (read_vector): Use ASET.
8067 * msdos.c (Frecent_doskeys): Use vcopy.
8068 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8069 (Finternal_merge_in_global_face): Use ASET and vcopy.
8070 * xfont.c (xfont_list_pattern): Likewise.
8072 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8074 * window.c (Fwindow_point): For the selected window always return
8075 the position of its buffer's point.
8076 (Fset_window_point): For the selected window always go in its
8077 buffer to the specified position.
8079 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8081 Setter macros for fontsets.
8082 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8083 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8084 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8087 2012-08-20 Glenn Morris <rgm@gnu.org>
8089 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8090 Don't assume that `ln -f' works.
8092 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8094 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8095 and later about non-assignments with no effect. See discussion at
8096 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8099 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8101 Inline setter functions for Lisp_Objects slots of struct specbinding.
8102 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8105 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8107 * window.c (select_window): Always make selected window's buffer
8110 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8112 Use AREF and ASET for docstrings of category tables.
8113 * category.h (CATEGORY_DOCSTRING): Use AREF.
8114 (SET_CATEGORY_DOCSTRING): Use ASET.
8115 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8117 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8119 Inline setter functions for hash table members.
8120 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8121 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8122 (set_hash_key_and_value, set_hash_index, set_hash_next)
8123 (set_hash_hash): New functions.
8124 * charset.c, fns.c: Adjust users.
8126 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8128 Inline getter and setter functions for per-buffer values.
8129 * buffer.h (per_buffer_default, set_per_buffer_default)
8130 (per_buffer_value, set_per_buffer_value): New functions.
8131 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8132 * buffer.c, data.c: Adjust users.
8134 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8136 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8138 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8140 Rely on <config.h> + <unistd.h> to declare 'environ',
8141 as gnulib does this if the system doesn't.
8142 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8143 Remove declaration. MS-Windows declares it on stdlib.h which is
8144 included by conf_post.h.
8145 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8146 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8147 * vm-limit.c: Include <unistd.h>, for 'environ'.
8149 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8150 (start_of_data): Remove decl; mem-limits.h provides it.
8152 * xdisp.c (handle_invisible_prop): Make it a bit faster
8153 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8155 2012-08-19 Chong Yidong <cyd@gnu.org>
8157 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8160 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8162 * .gdbinit: Use call instead of set when calling a function in the
8165 * data.c (set_internal): Don't use set_blv_found.
8166 (Fkill_local_variable): Likewise.
8168 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8170 * nsfont.m (ns_ascii_average_width): Ensure the string
8171 ascii_printable is initialized with a null-terminated character
8172 array. Otherwise, it can contain undesired extra characters.
8174 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8176 port new setting code to Sun C 5.8 2005/10/13
8177 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8178 Return void, not Lisp_Object. Otherwise, the compiler
8179 complains about (A?B:C) where B is void and C is Lisp_Object
8180 when compiling CHAR_TABLE_SET, due to the recent change to
8181 the API of sub_char_table_set_contents.
8183 2012-08-18 Chong Yidong <cyd@gnu.org>
8185 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8186 for the string case (Bug#3874).
8188 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8190 * buffer.h (BSET): Remove (Bug#12215).
8191 Replace all uses with calls to new setter functions.
8192 (bset_bidi_paragraph_direction, bset_case_canon_table)
8193 (bset_case_eqv_table, bset_directory, bset_display_count)

9072 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9073 more like a function. This is because the pointer cast is not
9074 needed. All uses changed.
9075 * print.c (print_string, print_error_message): Avoid length recalc.
9077 Improve fix for macroexp crash with debugging (Bug#12118).
9078 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9079 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9080 not supposed to be invoked from the garbage collector.
9081 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9082 (gc_aset): New function, which is like ASET but can be
9083 used in the garbage collector.

9112 with addition of handling of symlinks and support for 'lstat'.
9113 If possible, get file's attributes and security information by
9114 handle, not by name. Produce S_IFLNK bit for symlinks, when
9115 called from 'lstat'.
9116 (stat, lstat): New functions, call 'stat_worker'.
9117 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9118 symlinks when the underlying filesystem supports them.

9122 Fix macroexp crash on Windows with debugging (Bug#12118).
9123 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9124 checking subscripts; problem introduced with the recent
9125 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9126 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9127 since it's used in non-static inline functions now.
9129 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9130 Don't assume buffer size fits in 'int'. Remove unused local.

9150 * composite.c (COMPOSITE_INLINE):
9151 * dispnew.c (DISPEXTERN_INLINE):
9152 * sysdep.c (SYSTIME_INLINE):
9153 Define to EXTERN_INLINE, so that the corresponding functions
9154 are compiled into code.

9156 (INLINE_HEADER_END): New macros.
9157 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9179 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9181 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9182 This how ASET and AREF are supposed to work, and makes
9183 it easier to think about future improvements. See
9184 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9185 * charset.h (set_charset_attr): New function.

9567 (w32_kbd_patch_key, key_event): Use the codepage returned by
9568 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

9600 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9601 enumeration constants, as PURE and HEAP are too general, and clash
9602 with other headers and sources, such as gmalloc.c and the
9603 MS-Windows system headers. All users changed.
9605 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9607 Revert last save_excursion_save and save_excursion_restore changes.
9608 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9621 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9622 arms of an 'if', not using conditional expressions; otherwise GDB
9623 complains about the types in the unevaluated arm when the argument
9624 is an integer literal.
9625 (xgetint): Simplify expression.
9626 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9627 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9628 Zaretskii in <http://bugs.gnu.org/12036#13>.
9629 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9630 needed now that we have gdb_make_enums_visible.
9631 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9632 (enum enum_USE_LSB_TAG):
9633 New enum types, packaging up enums that need to be exported to GDB.

9657 * lisp.h (struct Lisp_Excursion): New data type.
9658 (PVEC_EXCURSION): New pseudovector type.
9659 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9660 to deal with it. Adjust comments.

9675 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9676 emacs.c, as this is a more-suitable home. Had this been done earlier
9677 the fix for 12036 would have avoided some of the problems noted in
9678 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9679 would have been more obvious.
9680 * emacs.c: Do not include <verify.h>; no longer needed.
9681 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9682 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9683 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

9687 (DATA_SEG_BITS): Use it.
9688 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9689 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9690 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9691 not be usable in #if. This simplifies things.
9693 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9695 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9697 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9700 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9701 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9702 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9703 Adjust to changes in lisp.h and emacs.c, by using
9704 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9705 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9706 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9707 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9708 instead of gdb_valbits.
9709 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9710 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9711 instead of gdb_array_mark_flag.
9712 (xboolvector): Get size from $->size, not $->header.size.
9713 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9714 (xreload, hook-run, hookpost-run): Remove.
9715 * emacs.c: Include <verify.h>.
9716 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9717 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9719 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9720 (gdb_USE_LSB_TAG): New enum constants.
9721 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9722 Also define these as enum constants, so they're visible to GDB.
9723 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9724 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9725 as constants, so they're visible to GDB.
9726 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9727 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9728 Now enum constants, not macros, so they're visible to GDB.
9729 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9730 more convenient now. All uses changed.
9731 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9732 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9734 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9741 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9742 add argument, tune behavior, and adjust all callers.
9744 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9746 Use typedef for EMACS_INT, EMACS_UINT.
9747 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9748 than macros. This simplifies debugging in the usual case, since
9749 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9750 and it allows expressions involving EMACS_INT casts.
9751 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9753 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9763 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9765 Adjust buffer text indirection counters at the end of Fkill_buffer.
9766 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9767 buffer is definitely dead. This should really fix an issue reported
9768 by Christoph Scholtes again. (Bug#12007).
9769 (init_buffer_once): Initialize indirection counters of
9770 buffer_defaults and buffer_local_symbols (for sanity and safety).
9772 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9774 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9775 and continuation glyphs on tooltip frames, leave them at zero.

9790 it signals an error when a tooltip frame is being created.
9792 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9794 Cleanup miscellaneous objects allocation and initialization.

9796 specify the subtype. Adjust comment and users.
9797 (build_overlay): New function.
9798 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9799 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

9801 (build_overlay): Add prototype.
9803 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9805 Swap buffer text indirection counters in Fbuffer_swap_text.
9806 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9807 This avoids crash reported by Christoph Scholtes at
9808 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9810 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9812 * nsmenu.m (Popdown_data): New struct.
9813 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9815 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9816 (initWithContentRect): Make imgView and contentView non-static
9817 and autorelease them. Also autorelease img and matrix (Bug#12005).
9818 (dealloc): Remove (Bug#12005).
9820 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9822 Adjust consing_since_gc when objects are explicitly freed.

9835 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9837 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9838 as it's limited by the amount of memory, not by INT_MAX.
9840 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9842 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9843 in special-event-map. See the discussion at
9844 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9847 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
9848 info.dwItemData. Fixes crashes on 64-bit Windows.

9902 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9903 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9904 Adjust users accordingly.
9905 * font.h (font_open_by_name): Adjust prototype.

9924 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9925 'for_each_per_buffer_object_at'.
9926 All uses changed. It's better to use upper-case for macros that
9927 cannot be implemented as functions, to give the reader a clue
9928 that they're special.
9930 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9932 * alloc.c (Fgarbage_collect): Tweak docstring.

10566 * s/aix4-2.h (unix): Remove; no longer needed.
10568 EMACS_TIME simplification (Bug#11875).
10569 This replaces macros (which typically do not work in GDB)

10571 The functional style also makes code easier to read and maintain.
10572 * systime.h: Include <sys/time.h> on all hosts, not just if
10573 WINDOWSNT, since 'struct timeval' is needed in general.
10574 (EMACS_TIME): Now a typedef, not a macro.

10588 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10589 (add_emacs_time, sub_emacs_time): New functions.
10590 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

10608 (menu_separator_name_p):
10609 * nsmenu.m (ns_update_menubar):
10610 Prefer memcmp to strncmp when either will do.
10611 * nsterm.m: Include <ftoastr.h>.
10613 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10614 Prefer snprintf to strncpy.
10615 * nsterm.m (ns_term_init):
10616 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10617 * nsterm.m (ns_term_init):
10618 Avoid the need for strncpy, by using build_string or
10619 make_unibyte_string directly. Use dtoastr, not snprintf.
10620 * process.c (Fmake_network_process): Diagnose service names that
10621 are too long, rather than silently truncating them or creating
10622 non-null-terminated names.

10624 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10625 Prefer sprintf to strncat.
10626 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

10638 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10639 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

10657 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10658 argument, adjust users accordingly. Use build_pure_c_string where

10661 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10662 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

10699 Now it does not set EMACSLOADPATH, just returns the load-path string.
10700 * nsterm.h: Update accordingly.
10701 * lread.c [HAVE_NS]: Include nsterm.h.
10702 (init_lread) [HAVE_NS]: Use ns_load_path.

10712 (ns_init_paths): Do not set EMACSPATH.

10772 Move marker debugging code under MARKER_DEBUG.
10773 * marker.c (MARKER_DEBUG): Move marker debugging code under
10774 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow

10821 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10822 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10823 Fix pointer signedness problem.
10824 * xfaces.c (FRAME_X_FONT_TABLE):
10825 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10827 2012-07-07 Glenn Morris <rgm@gnu.org>
10829 * lread.c (load_path_check): New function, split from init_lread.
10830 (init_lread): Reorganize. Motivation:
10831 If EMACSLOADPATH is set, check/warn about that rather than the
10832 defaults, which we are not going to use. Hence we can remove
10833 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10834 Don't warn if site-lisp directories are missing.
10835 If not installed, start from a blank load-path, since
10836 PATH_LOADSEARCH refers to the eventual installation directories.
10838 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10840 Support truncation and continuation glyphs on GUI frames, when
10841 fringes are disabled. (Bug#11832)
10842 * xdisp.c (init_iterator): Get dimensions of truncation and
10843 continuation glyphs even if on GUI frames.
10844 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10845 or both, are absent.
10846 (start_display, move_it_in_display_line_to): Handle the case of a
10847 GUI frame without a fringe to display continuation or truncation
10849 (insert_left_trunc_glyphs): Support GUI frames: make sure
10850 truncation glyphs overwrite enough glyphs from the current line to
10851 have sufficient space in pixels.
10852 (display_line): Support truncation and continuation glyphs on GUI
10853 frames. If some spare pixels are left on the line after inserting
10854 the truncation glyphs, fill that space with a stretch glyph of a
10855 suitably computed width.
10857 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10858 produce_glyphs, to support GUI sessions.
10860 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10862 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10864 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10866 Do not require float-time's arg to fit in time_t (Bug#11825).
10867 This works better on hosts where time_t is unsigned, and where
10868 float-time is applied to the (negative) difference between two times.
10869 * editfns.c (decode_time_components): Last arg is now double *,
10870 not int *, and means to store all the result as a double, without
10871 worrying about whether the seconds part fits in time_t.
10872 All callers changed.
10873 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10874 All callers changed.
10875 (Ffloat_time): Do not fail merely because the specified time falls
10876 outside of time_t range.
10878 2012-07-07 Glenn Morris <rgm@gnu.org>
10880 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10881 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10882 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10884 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10886 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10887 Update dependencies.
10889 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10891 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10893 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10894 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10895 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10896 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10897 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10898 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10900 * xfont.c (compare_font_names): Redo to omit the need for casts.
10902 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10904 * xfns.c (Fx_change_window_property): Doc fix.
10905 * w32fns.c (Fx_change_window_property): Doc fix.
10907 * w32fns.c (Fx_window_property): Accept the same arguments as the
10908 X Windows version. Doc fix.
10909 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10911 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10912 Eli Zaretskii <eliz@gnu.org>
10914 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10915 Windows-specific code from nt/config.nt moved here.
10916 Obsolete settings removed.
10918 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10920 * process.c: Avoid unnecessary calls to gettime.
10921 (wait_reading_process_output): Don't get the time of day
10922 when gobbling data immediately and not waiting, as there's no need
10923 for it in that case. This removes a FIXME.
10925 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10927 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10928 is defined (Bug#11768).
10930 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10932 Fix marker debugging code.
10933 * marker.c (byte_char_debug_check): Do not perform the check
10934 if buffer is not multibyte.
10935 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10936 Call byte_char_debug_check with correct arguments.
10938 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10940 Compile marker debugging code only if ENABLE_CHECKING is defined.
10941 * marker.c (byte_char_debug_check, count_markers):
10942 Use only if ENABLE_CHECKING is defined.
10943 (byte_debug_flag): Remove.
10944 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10945 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10947 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10949 Avoid code repetition in marker-related functions.
10950 * marker.c (attach_marker): New function.
10951 (Fset_marker, set_marker_restricted, set_marker_both)
10952 (set_marker_restricted_both): Use it.
10953 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10954 Consistently rename charno to charpos.
10955 (marker_position): Add eassert.
10956 (marker_byte_position): Convert to eassert.
10958 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10960 Simplify list operations in unchain_overlay and unchain_marker.
10961 * buffer.c (unchain_overlay): Simplify. Add comment.
10962 * marker.c (unchain_marker): Simplify. Fix comments.
10964 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10966 Introduce fast path for the widely used marker operation.
10967 * alloc.c (build_marker): New function.
10968 * lisp.h (build_marker): New prototype.
10969 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10970 * composite.c (autocmp_chars): Likewise.
10971 * editfns.c (buildmark): Remove.
10972 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10973 (save_restriction_save): Use build_marker.
10974 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10975 * window.c (save_window_save): Likewise.
10977 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10979 Do not use Fdelete_overlay in delete_all_overlays
10980 to avoid redundant calls to unchain_overlay.
10981 * buffer.c (drop_overlay): New function.
10982 (delete_all_overlays, Fdelete_overlay): Use it.
10983 * minibuf.c (get_minibuffer): Fix comment.
10985 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10987 Port to OpenBSD 5.1 amd64.
10988 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10989 This is needed for OpenBSD, and should be harmless on all BSD systems.
10990 Also, include <sys/sysctl.h>, as it should be available on all
10991 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10992 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10993 use p_pid member, not kp_proc.pid.
10995 2012-07-06 Glenn Morris <rgm@gnu.org>
10997 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10999 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11001 More xmalloc and related cleanup.
11002 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

11010 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11012 Omit needless casts involving void * pointers and allocation.
11013 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11014 as the former is more robust if P's type is changed.
11015 Prefer xzalloc to xmalloc + memset 0.
11016 Simplify malloc-or-realloc to realloc.
11017 Don't worry about xmalloc returning a null pointer.
11018 Prefer xstrdup to xmalloc + strcpy.
11019 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11021 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11022 alloca of a constant.
11024 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11026 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11027 hscroll is larger than the line width. Fixes long and futile
11028 looping inside extend_face_to_end_of_line (on a TTY) producing
11029 glyphs that are not needed and thrown away.
11031 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11033 * marker.c (set_marker_restricted_both): Simplify by using
11036 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11038 * editfns.c (region_limit): Simplify by using clip_to_bounds.
11040 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
11042 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
11043 not defined (Bug#11768).
11044 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
11045 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
11046 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
11047 followed by gtk_box_set_homogeneous (Bug#11768).
11048 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11049 (update_theme_scrollbar_width, xg_create_scroll_bar):
11050 Use gtk_scrollbar_new (Bug#11768).
11051 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11052 (is_box_type): New function (Bug#11768).
11053 (xg_tool_item_stale_p): Call is_box_type.
11054 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11055 with default display (Bug#11768).
11057 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11059 * xdisp.c (window_hscroll_limited): New function.
11060 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11061 coordinates when window's hscroll is set to insanely large
11062 values. (Bug#11857)
11064 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11066 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
11067 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

11125 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11127 * fileio.c (time_error_value): Check the right error number.
11128 Problem reported by Troels Nielsen in
11129 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11131 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11133 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11134 This should be fixed in a better way; see Eli Zaretskii in
11135 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11136 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11138 * fileio.c (time_error_value): Rename from special_mtime.
11139 The old name's problems were noted by Eli Zaretskii in
11140 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11142 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11143 This variable's comment says Emacs needs at least one GDB-visible
11144 symbol of type enum pvec_type, to work around GDB problems.
11145 The symbol's value doesn't matter.
11147 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11148 that causes compilation to fail on pre-C99 compilers.
11150 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11152 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11153 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11155 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11157 * buffer.c (init_buffer_once): Fix initialization of
11158 headers for buffer_defaults and buffer_local_symbols.
11159 Reported by Juanma Barranquero <lekktu@gmail.com>.
11161 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11163 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11164 * lisp.h (enum pvec_type): Use fewer bits.
11165 (PSEUDOVECTOR_SIZE_BITS): New constant.
11166 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11167 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11168 change in pvec_type.
11169 (PSEUDOVECTOR_TYPEP): New macro.
11170 (TYPED_PSEUDOVECTORP): Use it.
11171 * fns.c (internal_equal): Adapt code to extract pvectype.
11172 * emacs.c (gdb_pvec_type): Update type.
11173 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11174 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11175 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11176 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11177 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11178 abusing vector->header.next.nbytes.
11179 (live_vector_p): Use PVEC_TYPE.
11180 (mark_object): Adapt code to extract pvectype. Use switch.
11182 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11184 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11185 Tighten new eassert a bit.
11187 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11189 Fix compilation with --enable-gcc-warnings and -O1
11190 optimization level.
11191 * doprnt.c (doprnt): Change type of tem to int, initialize
11192 to avoid compiler warning. Add eassert.
11193 * search.c (simple_search): Initialize match_byte to avoid
11194 compiler warning. Add eassert.
11196 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11198 Avoid weird behavior with large horizontal scrolls.
11199 Without this change, for example, large hscroll values would
11200 mess up Emacs's display on Fedora 15 x86, presumably due to
11201 overflows in int calculations in the display code.
11202 Also, if buffers had long lines, Emacs would freeze.
11203 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11204 (set_window_hscroll): New function, containing the old guts of
11205 Fset_window_hscroll. Return the clipped value.
11206 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11207 This avoids the need to check against PTRDIFF_MAX.
11209 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11211 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11213 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11215 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11217 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11218 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11219 since GCC 4.4.6 issues a bogus warning for them.
11221 Fix bugs in file timestamp newness comparisons.
11222 * fileio.c (Ffile_newer_than_file_p):
11223 * lread.c (Fload): Use full timestamp resolution of files,
11224 not just the 1-second resolution, so that files that are only
11225 slightly newer still count as newer.
11226 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11227 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11229 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11231 * fileio.c: Improve handling of file time marker. (Bug#11852)
11232 (special_mtime): New function.
11233 (Finsert_file_contents, Fverify_visited_file_modtime):
11234 Use it to set special mtime values consistently.
11236 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11238 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11239 marker for non-existing file. (Bug#11852)
11241 2012-07-03 Glenn Morris <rgm@gnu.org>
11243 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11244 and did not make it into globals.h).
11246 2012-07-03 Tom Tromey <tromey@redhat.com>
11248 * window.c (Fset_window_margins, Fset_window_fringes)
11249 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11250 * textprop.c (Fprevious_property_change): No longer static.

11286 * lisp.h (Frandom): Make it visible to C.
11287 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new

11290 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11292 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11293 values which aren't power of 2.
11294 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11295 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11298 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11300 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

11304 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11306 * alloc.c (allocate_vector_block): Remove redundant
11307 calls to mallopt if DOUG_LEA_MALLOC is defined.
11308 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11309 avoid calls to mallopt if zero_vector is returned.
11311 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11313 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11314 is enabled, avoid dereferencing NULL current_sblock if
11317 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11319 Cleanup basic buffer management.
11320 * buffer.h (struct buffer): Change layout to use generic vector
11321 marking code. Fix some comments. Change type of 'clip_changed'
11322 to bitfield. Remove unused #ifndef old.
11323 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11324 (GET_OVERLAYS_AT): Fix indentation.
11325 (for_each_per_buffer_object_at): New macro.
11326 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11330 struct buffer. Fix comment.
11331 (mark_overlay): New function.
11332 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11333 Lisp area of struct buffer.
11334 (mark_object): Use it. Adjust marking of misc objects
11335 and related comments.
11337 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11339 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11340 wrapper that is not needed because the wrapped code is a no-op (zero
11341 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11342 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11344 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11346 * alloc.c (mark_buffer): Simplify. Remove prototype.
11347 (mark_object): Add comment. Reorganize marking of vector-like
11348 objects. Use CHECK_LIVE for all vector-like objects except buffers
11349 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11350 Avoid redundant calls to mark_vectorlike for bool vectors.
11352 2012-06-30 Glenn Morris <rgm@gnu.org>
11354 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11356 * epaths.in (PATH_SITELOADSEARCH): New.
11357 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11358 This is rather than relying on --enable-locallisppath elements
11359 having "site-lisp" in their names. (Bug#10208#25, 11658)
11361 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11363 * w32proc.c (sys_select): Accept and ignore one more argument.
11365 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11367 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11368 (pselect) [!MS_DOS]: Redirect to sys_select.
11370 * sysdep.c: Don't include dos.h and dosfns.h.
11372 * process.c (sys_select):
11373 * msdos.c (sys_select): Accept one more argument and ignore it.
11375 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11376 adapt data types and code to that.
11379 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11380 which clashes with the gnulib function of the same name.
11382 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11384 * font.c (font_style_to_value, font_style_symbolic)

11393 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11395 * xdisp.c (try_window_id): Undo last change.
11397 * w32.c (getwd): Adjust commentary about startup_dir.
11398 (init_environment): Always call sys_access, even in non-MSVC
11399 builds. Don't chdir to the directory of the Emacs executable.
11400 This undoes code from 1997 which was justified by the need to
11401 "avoid conflicts when removing and renaming directories". But its
11402 downside was that every relative file name was being interpreted
11403 relative to the directory of the Emacs executable, which can never
11404 be TRT. In particular, it broke sys_access when called with
11405 relative file names.
11406 (sys_access): Map GetLastError to errno.
11408 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11414 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11417 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

11420 Add QUIT to make the loop interruptible.
11422 2012-06-29 Glenn Morris <rgm@gnu.org>

11443 Avoid integer overflow on scroll-left and scroll-right.
11444 * window.c (HSCROLL_MAX): New macro.
11445 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11446 overflow when requested scroll falls outside ptrdiff_t range.
11448 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11450 * window.h (struct window): Change type of 'hscroll',
11451 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11452 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11453 Adjust users accordingly.
11454 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11455 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11456 from EMACS_INT to ptrdiff_t.

11600 Use sprintf return value instead of invoking strlen on result.
11601 In the old days this wasn't portable, since some sprintf
11602 implementations returned char *. But they died out years ago and
11603 Emacs already assumes sprintf returns int.
11604 Similarly for float_to_string.
11605 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11612 * xfns.c (syms_of_xfns):
11613 Use sprintf or float_to_string result to avoid need to call strlen.
11614 * data.c (Fnumber_to_string):
11615 Use make_unibyte_string, since the string must be ASCII.
11616 * lisp.h, print.c (float_to_string): Now returns int length.
11617 * term.c (produce_glyphless_glyph):
11618 Use sprintf result rather than recomputing it.
11620 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11651 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11653 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11654 `const char *' to `char *' to avoid compiler warning.
11656 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11658 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11659 instead of truncating it to 63 (admittedly a generous limit).
11661 * process.c: Fix spelling and caps in comments.
11663 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11665 * emacs.c (setpgrp): Remove definition, unused.

11716 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11722 This improves on the previous patch, which introduced a bug
11723 when time_t is unsigned and as wide as intmax_t.

11755 language ID in the event parameters.
11757 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11758 event.code, not the obscure "character set ID".
11760 2012-06-23 Chong Yidong <cyd@gnu.org>
11762 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11789 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11791 Support higher-resolution time stamps (Bug#9000).
11792 The time stamps are only nanosecond-resolution at the C level,
11793 since that's the best that any real-world system supports now.
11794 But they are picosecond-resolution at the Lisp level, as that's
11795 easy, and leaves room for future OS improvements.
11797 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11800 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11801 Don't get current time unless it's needed.
11803 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11804 now provides it if it's absent.
11805 (start_atimer): Port to higher-res time stamps.
11806 Check for time stamp overflow. Don't get current time more
11807 often than is needed.
11809 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11810 Include systime.h, not time.h.
11811 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11813 * dired.c: Include stat-time.h.
11814 (Ffile-attributes): File times now have higher resolution.
11816 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11817 (struct image): Timestamp now has higher resolution.
11819 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11820 has at least microseconds now. All uses removed.
11821 (update_frame, update_single_window, update_window, update_frame_1)
11822 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11823 (duration_to_sec_usec): Remove; no longer needed.
11825 * editfns.c (time_overflow): Now extern.
11826 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

11831 (decode_time_components, lisp_seconds_argument): New functions.
11832 (make_time): Now static.
11833 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11834 Report an error if the time is invalid, rather than having the caller
11837 * fileio.c: Include <stat-time.h>
11838 (Fcopy_file): Copy higher-resolution time stamps.
11839 Prefer to set the time stamp via a file descriptor if that works.
11840 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11841 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11842 (Fvisited_file_modtime, Fset_visited_file_modtime):
11843 Support higher-resolution time stamps.
11845 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11847 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11849 * image.c (prepare_image_for_display, clear_image_cache)
11850 (lookup_image): Port to higer-resolution time stamps.
11852 * keyboard.c (start_polling, bind_polling_period):
11853 Check for time stamp overflow.
11854 (read_char, kbd_buffer_get_event, timer_start_idle)
11855 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11856 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11857 Port to higher-resolution time stamps. Do not assume time_t is signed.
11858 (decode_timer): New function. Timers are now vectors of length 9,
11859 not 8, to accommodate the picosecond component.
11860 (timer_check_2): Use it.
11862 * nsterm.m (select_timeout, timeval_subtract): Remove.
11863 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11864 as they're a bit more accurate and handle overflow better.
11865 (ns_select): Change prototype to be compatible with pselect.
11866 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11867 * nsterm.h (ns_select): Adjust prototype.
11869 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11870 us-resolution time stamps.
11871 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11873 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11875 * lisp.h (time_overflow): New decl.
11876 (wait_reading_process_output): First arg is now intmax_t, not int,
11877 to accommodate larger waits.
11879 * process.h (struct Lisp_Process.read_output_delay):
11880 Now counts nanoseconds, not microseconds.
11881 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11883 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11884 (wait_reading_process_output):
11885 Port to ns-resolution time stamps.
11886 (Faccept_process_output, wait_reading_process_output):
11887 Check for time stamp overflow. Do not assume time_t is signed.
11888 (select_wrapper): Remove; we now use pselect.
11889 (Fprocess_attributes): Now generates ns-resolution time stamps.
11891 * sysdep.c: Include utimens.h. Don't include utime.h
11892 or worry about struct utimbuf; gnulib does that for us now.
11893 (gettimeofday): Remove; gnulib provides a substitute.
11894 (make_timeval): New function.
11895 (set_file_times): Now sets ns-resolution time stamps.
11896 New arg FD; all uses changed.
11897 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11898 (system_process_attributes):
11899 Now returns ns-resolution time stamp. All uses changed.
11900 Check for time stamp overflow.
11902 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11903 provides a substitute now.
11905 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11906 since it guarantees struct timespec.
11907 (EMACS_TIME): Now struct timespec, so that we can support
11908 ns-resolution time stamps.
11909 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11910 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11911 (EMACS_USECS): Remove.
11912 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11913 so multiply the arg by 1000 before storing it.
11914 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11916 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11917 Port to ns-resolution time stamps.
11918 (EMACS_TIME_NEG_P): Remove; replaced by....

11921 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11922 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11923 (make_timeval, make_lisp_time, decode_time_components): New decls.
11924 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11925 that it mishandled time_t overflow. You can't compare by subtracting!
11926 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11927 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11929 * term.c: Include <sys/time.h>.
11930 (timeval_to_Time): New function, for proper overflow wraparound.
11931 (term_mouse_position, term_mouse_click): Use it.
11933 * undo.c (record_first_change): Support higher-resolution time stamps
11934 in the undo buffer.
11935 (Fprimitive_undo): Use them when restoring time stamps.
11937 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11938 (w32_get_internal_run_time):
11939 Port to higher-resolution Emacs time stamps.
11940 (ltime): Now accepts single 64-bit integer, as that's more convenient
11943 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11945 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11946 for compatibility with pselect. Support ns-resolution time stamps.
11948 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11950 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11951 Check for time stamp overflow, and support ns-resolution time stamps.
11953 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11954 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11955 (timeval_subtract): Remove; no longer needed.
11956 (XTflash, XTring_bell, x_wait_for_event):
11957 Port to ns-resolution time stamps. Don't assume time_t is signed.
11959 2012-06-22 Chong Yidong <cyd@gnu.org>

11963 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11965 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11966 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11967 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11968 staticidx goes up to 1597 out of 1600 = 0x640.)
11970 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11972 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11973 Otherwise, the umask might be mistakenly 0 while handling input signals.
11975 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

11984 access to `contents' member of Lisp_Vector objects with AREF and ASET
11987 2012-06-19 Chong Yidong <cyd@gnu.org>
11989 * frame.c (delete_frame): When selecting a frame on a different
11990 text terminal, do not alter the terminal's top-frame.

11993 frame's selected window and its terminal's top-frame.
11994 (unwind_format_mode_line): Restore them.
11995 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11997 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

12006 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12007 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12008 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12009 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

12016 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12018 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12019 gets killed during executing of this function (Bug#11665).
12020 Try to always return Qt when the buffer has been actually killed.
12021 (Vkill_buffer_query_functions): In doc-string say that functions
12022 run by this hook should not change the current buffer.
12024 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12026 Fix recently-introduced process.c problems found by static checking.
12027 * process.c (write_queue_push, write_queue_pop, send_process):
12028 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12029 (write_queue_pop): Fix pointer signedness problem.
12030 (send_process): Remove unused local.
12032 2012-06-17 Chong Yidong <cyd@gnu.org>

12046 * lisp.h (eassert): Assume C89 or later.
12047 This removes the need for CHECK.
12048 (CHECK): Remove. Its comments about always evaluating its
12049 argument were confusing, as 'eassert' typically does not evaluate
12052 * coding.c (produce_chars): Use ptrdiff_t, not int.
12054 * xterm.c (x_draw_underwave): Check for integer overflow.
12055 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12212 * w32menu.c (add_menu_item): Likewise.

12228 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
12229 * alloc.c (make_number) [!defined make_number]:
12230 Remove, as lisp.h always defines this now.
12231 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
12232 (roundup_size): Verify that it is a power of 2.
12233 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

12236 -DUSE_LSB_TAG=0, to override the automatically-selected default.
12237 USE_LSB_TAG now is always defined to be either 0 or 1.
12239 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
12240 code works fine either way, and efficiency is not a concern here,
12241 as the union type is for debugging, not for production.
12242 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12243 Use an inline function on all platforms when using the union type,
12244 since this is simpler and 'static inline' can be used portably
12246 (LISP_INITIALLY_ZERO): New macro.
12247 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12248 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12276 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
12277 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
12279 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>

12312 tty_alt_charset_p. Add tty_italic_p.
12314 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
12316 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
12317 dbus_type_is_basic if available.
12318 (xd_extract_signed, xd_extract_unsigned): Rename from
12319 extract_signed and extract_unsigned, respectively. Adapt callers.

12330 * xdisp.c (vmessage): Treat frame message as multibyte.
12331 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
12332 would generate the diagnostic "Making \302\247 buffer-local while
12335 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12337 * dispnew.c (showing_window_margins_p): Undo last change, which
12338 was done due to an inadvertent commit.
12339 (adjust_frame_glyphs_for_frame_redisplay): Do call

12348 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
12350 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12351 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12353 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12355 * alloc.c (allocate_vectorlike): Fix last change.
12357 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12359 Block-based vector allocation of small vectors.
12360 * lisp.h (struct vectorlike_header): New field `nbytes',
12361 adjust comment accordingly.
12362 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12363 to denote vector blocks. Adjust users (live_vector_p,

12386 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12388 * doprnt.c (doprnt): Truncate multibyte char correctly.
12389 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12390 would mishandle a string argument "Xc" if X was a multibyte
12391 character of length 2: it would truncate after X's first byte
12392 rather than including all of X.
12394 2012-06-06 Chong Yidong <cyd@gnu.org>
12396 * buffer.c (word_wrap): Doc fix.
12398 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

12427 Fbuffer_local_value; can return Qunbound.
12428 (Fbuffer_local_value): Use it.
12429 (Vmode_line_format): Docstring tweaks.

12443 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12445 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12446 Convert pctcpu and pctmem to Lisp float properly.
12447 Let the compiler fold better, as 100.0/0x8000 is exact.
12449 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12451 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12454 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12458 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12460 For a 'struct window', replace some Lisp_Object fields to
12461 bitfields where appropriate, remove unused fields.
12462 * window.h (struct window): Remove unused 'last_mark_x' and
12463 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12464 change its type from Lisp_Object to bitfield.
12465 Change type of 'force_start', 'optional_new_start',
12466 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12467 fields from Lisp_Object to bitfield. Adjust users accordingly.

12471 Pacify gcc -Wdouble-precision when using Xaw.
12472 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12473 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12474 Use 'float' consistently, rather than 'float' in most places
12475 and 'double' in a couple of places.
12477 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12479 * xdisp.c (handle_stop): Detect whether we have overlay strings
12480 loaded by testing it->current.overlay_string_index to be
12481 non-negative, instead of checking whether n_overlay_strings is
12482 positive. (Bug#11587)
12484 2012-05-31 Chong Yidong <cyd@gnu.org>
12486 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12492 * search.c (search_buffer): Remove calls to
12493 r_alloc_inhibit_buffer_relocation, as it is now called by
12494 maybe_unify_char, which was the cause of relocation of buffer text
12497 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12499 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12500 for the duration of call to load_charset, to avoid problems with
12501 callers of maybe_unify_char that access buffer text through C
12504 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12505 decrement the inhibition flag, instead of just setting or
12508 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12510 Remove obsolete '#define static' cruft.
12511 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12512 This #undef was "temporary" in 2000; it is no longer needed
12513 now that '#define static' has gone away.
12514 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12515 (gray_bitmap_bits): Remove; no longer needed.
12516 All uses replaced with definiens.

12528 (safe_bcopy): Remove decl; no longer has that name.
12529 (main): Coalesce #if into single bit of code, for simplicity.
12530 Cast pointers to uintptr_t, since standard libraries want integers

12559 Do not create empty overlays with the evaporate property (Bug#9642).
12560 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12561 Bug#9642, but explicitly check that the buffer the overlay would
12562 be moved to is live and rearrange lines to make sure that errors
12563 will not put the overlay in an inconsistent state.
12564 (Fdelete_overlay): Cosmetics.
12566 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12568 * w32term.c (my_bring_window_to_top): New function.
12569 (x_raise_frame): Use handle returned by DeferWindowPos, which

12580 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12582 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12583 This avoids undefined behavior that might cause the eassert
12584 to not catch an out-of-range value.
12586 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12588 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12603 Only r_alloc_inhibit_buffer_relocation needed to be added;
12604 the others were already declared.
12606 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12607 before checking whether it's out of range. Put the check inside
12609 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

12627 * search.c (search_buffer): Use it to inhibit relocation of buffer
12628 text while re_search_2 is doing its job, because re_search_2 is
12629 passed C pointers to buffer text. (Bug#11519)
12631 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12632 Update value to 24.
12634 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

12644 Fix coding-related core dumps with gcc -ftrapv.
12645 The code was computing A - B, where A and B are pointers, and B is
12646 random garbage. This can lead to core dumps on platforms that
12647 have special pointer registers, and it also leads to core dumps on
12648 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12649 A - B only when B is initialized properly.
12650 * coding.c (coding_set_source, coding_set_destination): Return void.
12651 (coding_change_source, coding_change_destinations): New functions,
12652 with the old behaviors of coding_set_source and coding_set_destination.

12672 moves, call note_mouse_highlight. If help_echo changed, call
12673 gen_help_event to produce help-echo message in the echo area.
12674 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12677 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12679 * lread.c (read1): Simplify slightly to avoid an overflow warning
12680 with GCC 4.7.0 on x86-64.
12682 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12684 * bidi.c (bidi_mirror_char): Revert last change: an int is
12685 definitely wide enough here.
12687 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

12701 Use int, not EMACS_INT, where int is wide enough.
12702 (inhibit_garbage_collection, Fgarbage_collect):
12703 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12704 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12705 int might not be wide enough.

12723 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12724 (validate_region): Omit unnecessary test for b <= e,
12725 since that's guaranteed by the previous test.
12726 (adjust_overlays_for_delete): Avoid pos + length overflow.
12727 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12728 (report_overlay_modification):
12729 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12730 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12731 Omit pointer cast, which isn't needed anyway, and doesn't work
12732 after the EMACS_INT -> ptrdiff_t change.
12733 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12734 * buffer.h: Adjust decls to match defn changes elsewhere.

12739 not int, to avoid needless 32-bit limit on 64-bit hosts.
12740 (exec_byte_code): Use tighter memory-full test, one that checks
12741 for alloca overflow. Don't compute the address of the object just
12742 before an array, as that's not portable. Use EMACS_INT, not
12743 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12744 * callint.c (Fcall_interactively):
12745 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12746 * callproc.c (call_process_kill, Fcall_process):
12747 Don't assume pid_t fits into an Emacs fixnum.

12757 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12758 (casify_object): Avoid integer overflow when overallocating buffer.
12759 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

12762 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12763 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12769 Check that Vcode_version_map_vector is a vector.
12770 (resolve_symbol_ccl_program): Check that vector header is in range.
12771 Always copy the vector, so that we can check its contents reliably
12772 now rather than having to recheck each instruction as it's being
12773 executed. Check that vector words fit in 'int'.
12774 (ccl_get_compiled_code, Fregister_ccl_program)
12775 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12776 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12777 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12778 contents are in range.
12779 (Fccl_execute_on_string): Check that status is in range.
12780 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12781 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12782 Accept and return EMACS_INT, not int, because callers can pass values
12783 out of 'int' range.

12789 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12790 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12791 avoid mishandling large integers.

12800 Remove now-unnecessary CHECK_NATNUMs.
12801 (Fdefine_charset_internal): Check ranges here, more carefully.
12802 Don't rely on undefined behavior with signed left shift overflow.
12803 Don't assume unsigned int fits into fixnum, or that fixnum fits
12804 into unsigned int. Don't require max_code to be a valid fixnum;
12805 that's not true for gb10830 4-byte on a 32-bit host. Allow
12806 invalid_code to be a cons, for the same reason. Require code_offset
12807 to be a character. Avoid int overflow if max_char is close
12809 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12810 this is intended anyway and avoids some undefined behavior.
12811 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12812 INDEX_TO_CODE_POINT, as that's what it expects.
12813 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12814 * charset.h (DECODE_CHAR): Return int, not unsigned;
12815 this is what was intended anyway, and it avoids undefined behavior.
12816 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12817 integer-overflow issues.
12818 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12819 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12820 where the argument is EMACS_INT, and this behavior is not intended.
12821 * chartab.c (Fmake_char_table, Fset_char_table_range)
12822 (uniprop_get_decoder, uniprop_get_encoder):
12823 Don't assume fixnum fits in int.
12824 * cmds.c (move_point): New function, that does the gist of
12825 Fforward_char and Fbackward_char, but does so while checking
12826 for integer overflow more accurately.
12827 (Fforward_char, Fbackward_char): Use it.
12828 (Fforward_line, Fend_of_line, internal_self_insert)
12829 (internal_self_insert):
12830 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13611 2012-05-14 Glenn Morris <rgm@gnu.org>

13618 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

13621 (report_error, report_error_1, make_hdr, copy_sym)
13622 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13623 Make arguments const char *, not char *, to avoid violations of C
13624 standard and to fix some AIX warnings reported by Gilles Pion.
13626 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13628 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13629 already have overlays loaded.
13630 (handle_single_display_spec): Before returning without displaying
13631 fringe bitmap, synchronize the bidi iterator with the main display
13632 iterator, by calling iterate_out_of_display_property.
13633 (iterate_out_of_display_property): Detect buffer iteration by
13634 testing that it->string is a Lisp string.
13635 (get_next_display_element): When the current object is exhausted,
13636 and there's something on it->stack, call set_iterator_to_next to
13637 proceed with what's on the stack, instead of returning zero.
13638 (set_iterator_to_next): If called at the end of a Lisp string,
13639 proceed to consider_string_end without incrementing string
13640 position. Don't increment display vector index past the end of
13641 the display vector. (Bug#11417)
13642 (pos_visible_p): Don't report a position visible when move_it_to
13643 stopped at the last line of window, which happens to be scanned
13644 backwards by the bidi iteration. (Bug#11464)
13646 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13648 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13649 and right-margin display specs even if the spec is invalid or we
13650 are on a TTY, and thus unable to display on the fringes.
13651 That's because the text with the property will not be displayed anyway,
13652 so we need to signal to the caller that this is a "replacing"
13653 display spec. This fixes display when the spec is invalid or we
13656 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13658 * unexaix.c (make_hdr): Fix typo in prototype.
13659 This bug broke the build on AIX. Problem reported by Gilles Pion.

13674 2012-05-12 Glenn Morris <rgm@gnu.org>
13676 * Makefile.in (MKDIR_P): New, set by configure.
13677 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

13689 Update dependencies.
13691 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13693 * xgselect.c (xg_select): Put maxfds+1 into a var.
13694 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13696 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13698 2012-05-10 Dave Abrahams <dave@boostpro.com>
13700 * filelock.c (syms_of_filelock): New boolean create-lockfiles.

13703 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13705 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13706 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13707 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13708 Initialize xd_registered_buses.
13710 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13712 Untag more efficiently if USE_LSB_TAG.
13713 This is based on a proposal by YAMAMOTO Mitsuharu in
13714 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13715 For an admittedly artificial (nth 8000 longlist) benchmark on
13716 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13717 Emacs's overall text size by 1%.
13718 * lisp.h (XUNTAG): New macro.
13719 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13720 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13721 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13722 * eval.c (Fautoload):
13723 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13724 * frame.h (XFRAME): Use XUNTAG.
13726 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13727 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13728 Remove unportable assumptions about print widths of types like
13730 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13731 intptr_t when converting between pointer and integer, to avoid GCC
13732 warnings about wrong width.
13734 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13736 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13737 stack for each reader_thread, instead of defaulting to 8MB
13738 determined by the linker. This avoids failures in creating
13739 subprocesses on Windows 7, see the discussion in this thread:
13740 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13742 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13744 Fix up display of the *Minibuf-0* buffer in the mini window.
13745 * keyboard.c (read_char): Don't clear the echo area if there's no
13747 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13748 contents of *Minibuf-0*) if there's no message displayed in its stead.
13750 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13752 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13755 2012-05-06 Chong Yidong <cyd@gnu.org>
13757 * lisp.mk (lisp): Update.
13759 2012-05-05 Jim Meyering <meyering@redhat.com>
13761 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13763 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13765 * data.c (PUT_ERROR): New macro.
13766 (syms_of_data): Use it. Add new error type `user-error'.
13767 * undo.c (user_error): New function.
13768 (Fprimitive_undo): Use it.
13769 * print.c (print_error_message): Adjust print style for `user-error'.
13770 * keyboard.c (user_error): New function.
13771 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13773 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13775 Do not limit current-time-string to years 1000..9999.
13776 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13777 (Fcurrent_time_string): Support any year that is supported by the
13778 underlying localtime representation. Don't use asctime, as it
13779 has undefined behavior for years outside the range -999..9999.
13781 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13783 Fix race conditions involving setenv, gmtime, localtime, asctime.
13784 Without this fix, interrupts could mess up code that uses these
13785 nonreentrant functions, since setting TZ invalidates existing
13786 tm_zone or tzname values, and since most of these functions return
13787 pointers to static storage.
13788 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13789 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13790 Grow the critical sections to include not just invoking
13791 localtime/gmtime, but also accessing these functions' results
13792 including their tm_zone values if any, and any related TZ setting.
13793 (format_time_string): Last arg is now struct tm *, not struct tm **,
13794 so that the struct tm is saved in the critical section.
13795 All callers changed. Simplify allocation of initial buffer, partly
13796 motivated by the fact that memory allocation needs to be outside
13797 the critical section.
13799 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13801 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13802 with RESET_INTERVAL.
13804 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13805 Remove duplicated buffer name initialization.
13807 2012-05-02 Jim Meyering <jim@meyering.net>
13809 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13811 * xfns.c (x_window): Use xstrdup (Bug#11375).
13813 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13815 * xdisp.c (pos_visible_p): If already at a newline from the
13816 display string before the 'while' loop, don't walk back the glyphs
13817 from it3.glyph_row. Solves assertion violation when the display
13818 string begins with a newline (egg.el). (Bug#11367)
13820 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13822 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13825 2012-05-01 Glenn Morris <rgm@gnu.org>
13827 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13828 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13829 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13830 All were removed before 23.1.
13832 * dispnew.c: Remove HAVE_LIBNCURSES test;
13833 it is always true on relevant platforms.
13835 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13836 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13838 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13840 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13842 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13843 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13846 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13848 Do not avoid creating empty evaporating overlays (Bug#9642).
13849 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13850 That is, do not delete an evaporating overlay if it becomes
13851 empty after its bounds are adjusted to fit within its buffer.
13852 This fix caused other problems, and I'm reverting it until we get
13853 to the bottom of them.
13855 2012-04-27 Chong Yidong <cyd@gnu.org>
13857 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13859 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13861 * xdisp.c (pos_visible_p): If the window start position is beyond
13862 ZV, start the display from buffer beginning. Prevents assertion
13863 violation in init_iterator when the minibuffer window is scrolled
13864 via the scroll bar.
13866 * window.c (window_scroll_pixel_based): Likewise.
13868 2012-04-27 Chong Yidong <cyd@gnu.org>
13870 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13872 2012-04-27 Glenn Morris <rgm@gnu.org>
13874 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13875 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13877 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13879 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13880 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13882 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13884 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13885 display element, check also the underlying string or buffer
13886 character. (Bug#11341)
13888 * w32menu.c: Include w32heap.h.
13889 (add_menu_item): If the call to AppendMenuW (via
13890 unicode_append_menu) fails, disable Unicode menus only if we are
13891 running on Windows 9X/Me.
13893 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13895 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13896 (xgetint): Add missing shift for LSB tags.
13898 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13900 * keyboard.c (read_char): Don't wipe echo area for select window
13901 events: These might get delayed via `mouse-autoselect-window'
13904 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13906 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13907 manipulation of :loaded-from data.
13909 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13911 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13912 now a cons (bug#11311).
13914 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13916 Do not create empty overlays with the evaporate property (Bug#9642).
13917 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13918 if it becomes empty after its bounds are adjusted to fit within
13919 its buffer. Without this fix, in a nonempty buffer (let ((o
13920 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13921 yields an empty overlay that has the evaporate property, which is
13922 not supposed to happen.
13924 Fix minor GTK3 problems found by static checking.
13925 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13930 (emacs_fixed_class_init): Omit unused local.
13931 (emacs_fixed_child_type): Remove; unused.

13933 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13934 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13935 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13936 (EMACS_FIXED_GET_CLASS): Remove; unused.
13937 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13939 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13940 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13942 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13944 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13945 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13946 (__malloc_size_t, __malloc_ptrdiff_t):
13947 Remove. All uses removed, replaced by the definiens if needed,
13948 since we can assume C89 or better now.
13949 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13950 (protect_malloc_state, align, get_contiguous_space)
13951 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13956 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13957 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13958 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13959 Define using prototypes, not old style.
13960 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13961 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

13966 Omit no-longer-needed casts.
13967 (valloc): Use getpagesize, not __getpagesize.
13968 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13969 (struct hdr): The 'magic' member is now size_t, not unsigned long.

14021 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
14022 Do not assume ptrdiff_t is the same width as 'int'.
14024 * alloc.c: Handle unusual debugging option combinations.
14025 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14026 since the two debugging options are incompatible.
14027 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14029 (mem_init, mem_insert, mem_insert_fixup):
14030 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

14040 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14041 Use Emacs indenting style more consistently. Avoid some casts.

14081 row, return zero immediately.
14082 (try_cursor_movement): If inside continuation line, don't back up
14083 farther than the first row after the header line, if any.
14084 Don't consider the header-line row as "partially visible", even if
14085 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

14123 New extern decls, to avoid calling undeclared functions.
14124 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14125 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14126 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14127 (NEED_MEM_INSERT): New macro.
14128 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14129 Remove one incorrect comment and fix another.

14138 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14139 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
14140 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
14141 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

14143 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14144 Remove decls. This fixes an "It stinks!".
14146 * alloc.c (which_symbols): Fix alignment issue / type clash.
14148 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14150 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14151 (struct Lisp_Misc_Any): Likewise.
14152 (struct Lisp_Free): Likewise.
14153 * alloc.c (union aligned_Lisp_Symbol): Define.
14154 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
14155 aligned_Lisp_Symbol instead of struct Lisp_Symbol.

14161 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
14163 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14164 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14165 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14166 * s/netbsd.h, s/sol2-6.h:
14167 Remove definition of GC_MARK_STACK, since the default now works.
14168 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14169 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14170 no longer the default.
14171 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14173 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14175 * lread.c (lisp_file_lexically_bound_p):
14176 Fix hang at ";-*-\n" (bug#11238).
14178 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14180 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14181 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

14192 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14194 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14196 2012-04-11 Daniel Colascione <dancol@dancol.org>
14198 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14199 against is gone. It's better to use vfork now so that when Cygwin
14200 gains a new, working vfork, we use it automatically (bug#10398).
14202 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14220 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14222 * w32.c (w32_delayed_load): Record the full path of the library
14223 being loaded (bug#10424).
14225 2012-04-09 Glenn Morris <rgm@gnu.org>
14227 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14228 not just in the obarray, before snarfing them. (Bug#11036)
14230 * Makefile.in ($(leimdir)/leim-list.el):
14231 Pass EMACS rather than BUILT_EMACS.
14233 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14235 * process.c (make_process):
14236 * process.h: Add integer `gnutls_handshakes_tried' member to

14245 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14246 attempts per process (connection).
14248 2012-04-09 Chong Yidong <cyd@gnu.org>
14250 * eval.c (Fuser_variable_p, user_variable_p_eh)
14251 (lisp_indirect_variable): Functions deleted.
14252 (Fdefvar): Caller changed.
14254 * callint.c (Finteractive, Fcall_interactively):
14255 * minibuf.c (Fread_variable): Callers changed.
14257 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14259 * xdisp.c (set_cursor_from_row): If the display string appears in
14260 the buffer at position that is closer to point than the position
14261 after the display string, display the cursor on the first glyph of
14262 the display string. Fixes cursor display when a 'display' text
14263 property immediately follows invisible text. (Bug#11094)
14265 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14267 composite.c: use 'double' consistently
14268 * composite.c (get_composition_id): Use 'double' consistently
14269 instead of converting 'float' to 'double' and vice versa; this is
14270 easier to understand and avoids a GCC warning.
14272 2012-04-09 Glenn Morris <rgm@gnu.org>
14274 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14275 preparation for dumping it with emacs. (Bug#4789)
14276 (leimdir): New variable.

14296 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14297 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14298 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14299 objects, as mark_maybe_pointer will catch them otherwise.

14308 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14310 Support building on MS-Windows with libxml2.
14312 * makefile.w32-in (OBJ2): Add xml.$(O).
14313 (GLOBAL_SOURCES): Add xml.c.
14314 ($(BLD)/xml.$(O)): New dependency list.
14316 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14317 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14318 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14319 [!WINDOWSNT]: New macros.
14320 (init_libxml2_functions, libxml2_loaded_p): New functions.
14321 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14322 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14323 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14324 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14326 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14327 Call init_libxml2_functions before calling libxml2 functions.
14328 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14330 * emacs.c: Don't include libxml/parser.h.
14331 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14332 xmlCleanupParser directly.
14334 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14336 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14338 * indent.c (Fvertical_motion): If there is a display string at
14339 point, use it.vpos to compute how many lines to backtrack after
14340 move_it_to point. (Bug#11133)
14342 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14344 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14345 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14346 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14347 macros related to unification of CJK characters. For the details,
14348 see the discussion following the message here:
14349 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14351 2012-04-04 Chong Yidong <cyd@gnu.org>
14353 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14355 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14357 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14365 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14367 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14368 position we get to after a call to move_it_to fails the
14369 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14370 only if we wind up in a string from display property. (Bug#11063)
14372 * window.c (Fdelete_other_windows_internal): Invalidate the row
14373 and column information about mouse highlight, so that redisplay
14374 restores it after reallocating the glyph matrices. (Bug#7464)
14376 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14377 string comes from a `display' text property, use the buffer
14378 position of that property as if we actually saw that position in
14380 (move_it_by_lines): Remove the assertion that
14381 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14382 violated when there's a before-string at the beginning of a line.
14385 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14387 * xdisp.c (append_space_for_newline): If the default face was

14389 (extend_face_to_end_of_line): Use the remapped default face for
14390 extending the face to the end of the line.
14391 (display_line): Call extend_face_to_end_of_line when the default
14392 face was remapped. (Bug#11068)
14394 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14396 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

14420 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14422 2012-03-25 Kenichi Handa <handa@m17n.org>
14424 * dispextern.h (struct glyph): Change the bit length of
14425 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14427 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14429 * s/ms-w32.h (tzname): Include time.h before redirecting to

14438 !SYNC_INPUT. (Bug#11080)
14440 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14442 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14443 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14444 when fetching a multibyte character consumes more bytes than
14445 CHAR_BYTES returns, due to unification of CJK characters in
14446 string_char. (Bug#11073)
14448 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14450 * process.c (wait_reading_process_output): Handle pty disconnect
14451 by refraining from sending oneself a SIGCHLD (bug#10933).

14485 that is not from display property, accept the row as a "cursor
14486 row" if one of the string's character has a non-nil `cursor'
14487 property. Fixes cursor positioning when there are newlines in
14488 overlay strings, e.g. in icomplete.el. (Bug#11035)
14490 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14492 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14494 2012-03-12 Chong Yidong <cyd@gnu.org>
14496 * eval.c (inhibit_lisp_code): Rename from
14497 inhibit_window_configuration_change_hook; move from window.c.
14499 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14500 * window.c (run_window_configuration_change_hook)
14501 (syms_of_window): Callers changed.
14503 2012-03-11 Chong Yidong <cyd@gnu.org>

14516 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14518 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14520 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14521 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14524 2012-03-03 Glenn Morris <rgm@gnu.org>
14526 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14528 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14534 (redisplay_window): Pass to move_it_vertically the margin in
14535 pixels, not in screen lines.
14537 2012-03-02 Glenn Morris <rgm@gnu.org>
14539 * buffer.c (buffer-list-update-hook): Doc fix.
14541 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14543 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14544 push_it before setting up the iterator for the first overlay
14545 string, even if we have an empty string loaded.
14546 (next_overlay_string): If there's an empty string on the iterator
14547 stack, pop the stack. (Bug#10903)
14549 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14551 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14552 Suggested by Stefan Monnier in
14553 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14554 * alloc.c (widen_to_Lisp_Object): New static function.
14555 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14556 and widening them to Lisp_Objects. This would work even if
14557 USE_LSB_TAG is defined and wide integers are used, which might
14558 happen in a future version of Emacs.
14560 2012-02-25 Chong Yidong <cyd@gnu.org>
14562 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

14599 when computing $valmask.
14601 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14602 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14603 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14604 It's useless in that case, and it can cause problems on hosts
14605 that allocate halves of EMACS_INT values separately.
14606 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14607 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14608 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14609 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14610 it avoids undefined behavior on hosts where shifting right by more
14611 than the word width has undefined behavior.

14737 * character.c (char_width): Return EMACS_INT, not int.
14738 (char_width, c_string_width): Check for overflow when

15228 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15229 verifies glyph row's hash code--we have just reallocated the

15413 behave as if the cursor position were at the window margin.
15415 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15416 and the cursor position is out of bounds, behave as if the cursor
15417 position were at the window margin. (Bug#10075)
15419 2011-11-18 Chong Yidong <cyd@gnu.org>

15447 * dispnew.c (verify_row_hash): Call row_hash for computing the
15448 hash code of a row, instead of duplicating code from xdisp.c.
15450 * dispextern.h (row_hash): Add prototype.
15452 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

15557 Avoid some portability problems by eschewing 'extern inline' functions.
15558 The trivial performance wins aren't worth the portability hassles; see
15559 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15561 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15599 (Fset_window_new_total, Fset_window_new_normal)
15600 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
15601 (delete_all_subwindows): Rename to delete_all_child_windows.
15602 (Fdelete_other_windows_internal, Fset_window_configuration):
15603 Call delete_all_child_windows instead of delete_all_subwindows.
15604 * frame.c (delete_frame): Call delete_all_child_windows instead

15607 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
15609 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
15610 This is also needed for porting to any host where GC_MARK_STACK is
15611 not GC_MAKE_GCPROS_NOOPS.
15612 (which_symbols): Use it.
15614 2011-11-07 Kenichi Handa <handa@m17n.org>

15627 * xmenu.c (cleanup_widget_value_tree): New function.
15628 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15629 calling free_menubar_widget_value_tree directly (Bug#9830).
15631 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15633 Fix some portability problems with 'inline'.

15635 (window_box_width, window_box_left, window_box_left_offset)
15636 (window_box_right, window_box_right_offset): Declare extern.
15637 Otherwise, these inline functions do not conform to C99 and
15638 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15639 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15640 * intervals.c (adjust_intervals_for_insertion)
15641 (adjust_intervals_for_deletion): Now extern, because otherwise the

15643 (static_offset_intervals): Remove.
15644 (offset_intervals): Rewrite using the old contents of
15645 static_offset_intervals. The old version didn't conform to C99
15646 because an extern inline function contained a reference to an
15647 identifier with static linkage.
15649 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15651 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15669 (Fwindow_vscroll): Doc fix.

15671 argument, since it makes no sense to pass a live window and for
15672 consistency with window-child.

15700 (unwind_create_frame): New function (Bug#9943).
15701 (Fx_create_frame): Restructure code to be more similar to the one in
15702 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

15712 Move terminal->reference_count++ just before making the frame
15713 official. Move initialization of image_cache_refcount and
15714 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15959 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15960 * editfns.c: Rewrite current-time-zone so that it invokes
15961 the equivalent of (format-time-string "%Z") to get the time zone name.
15962 This fixes a bug when the time zone name contains characters that
15963 need converting from the system time locale to Emacs internal format.
15964 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15965 that patch fixed format-time-string to do the conversion, but
15966 I forgot to fix current-time-zone.
15967 (format_time_string): New function, containing most of
15968 what Fformat_time_string used to contain.
15969 (Fformat_time_string): Rewrite in terms of format_time_string.
15970 This doesn't change this function's behavior.

15973 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15974 Jason Rumney's 2007-06-07 change worked around this bug, but
15976 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15978 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15980 * xdisp.c (start_display): If the character at POS is displayed
15981 via a display vector, reset IT->current.dpvec_index to zero.
15982 (try_window_reusing_current_matrix): If a line ends in a display
15983 vector or the next line starts in a display vector, continue
15984 redrawing the window even though the character position of
15985 start_row was reached.
15988 2011-10-18 Chong Yidong <cyd@gnu.org>
15990 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15991 with nobreak-char-display too.
15993 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15995 Fix part 3 of bug#9771.
15996 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15997 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15998 non-neutral characters if the current character is a paragraph
15999 separator (a.k.a. Newline). This avoids running the same
16000 expensive loop twice, once when we consume the preceding newline
16001 and the other time when the line actually needs to be displayed.
16002 Avoid the loop when we see neutrals on the base embedding level
16003 following a character whose directionality is the same as the
16004 paragraph's. This avoids running the expensive loop when a line
16005 ends in a long sequence of neutrals, like control characters.
16006 Add assertion against STRONG_AL type. Slightly rearrange code
16007 that determines the type of a neutral given the first non-neutral
16009 (bidi_level_of_next_char): Set next_en_pos to zero when
16010 invalidating its info.
16012 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16014 * xdisp.c (push_display_prop): Determine whether to record string
16015 or buffer position by IT->string, not by IT->method. Allow
16016 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16017 (move_it_vertically_backward): Don't look for character position
16018 immediately after the newline when in a continuation line.
16021 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16023 * window.c (coordinates_in_window): Rewrite and delabelize
16024 vertical border check. (Bug#5357) (Bug#9618)
16026 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16028 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16029 errors in XSetWindowBorder (bug#9310).
16031 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16033 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16034 avoid crash when xmalloc overrun checking is enabled.
16036 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16038 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16039 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16040 cursor motion with <left> and <right> arrow keys.
16042 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16043 some callers set that themselves.
16045 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16047 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16048 display string and the previous row comes from the same string and
16049 is empty. (Bug#9739) (Bug#9738)
16051 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16053 * doc.c (get_doc_string): Encode file name (bug#9735).
16055 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16057 * bidi.c (bidi_level_of_next_char):
16058 * xdisp.c (get_visually_first_element): Remove old incorrect
16059 comments regarding the Unicode Line Separator character.
16061 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16063 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16065 * alloc.c (Fgc_status): Do not access beyond zombies array
16066 boundary if nzombies > MAX_ZOMBIES.
16067 * alloc.c (dump_zombies): Add missing format specifier.
16069 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16071 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16072 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16074 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16075 Some packages use them to denote characters with modifiers.
16077 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16079 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16080 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16081 matching a pp-number. Rename parameter var to var1.
16083 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16085 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16087 2011-10-08 Glenn Morris <rgm@gnu.org>
16089 * callint.c (Fcall_interactively): Give a more explicit error for the
16090 'c' case with a non-character input. (Bug#8479)
16092 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16094 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16096 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16097 lines that are hscrolled on the left.
16099 * dispnew.c (buffer_posn_from_coords): Account for a possible
16100 presence of header-line. (Bug#4426)
16102 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16104 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16105 Don't advertise functionality which we discourage or doesn't work.
16107 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16109 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16110 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16111 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16112 this makes Emacs dump core during garbage collection on rare
16113 occasions. sizeof is obviously inferior to offsetof here, so
16114 stick with offsetof.
16115 (GC_POINTER_ALIGNMENT): New macro.
16116 (mark_memory): Omit 3rd (offset) arg; caller changed.
16117 Don't assume EMACS_INT alignment is the same as pointer alignment.
16119 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16121 * keyboard.c (read_key_sequence_remapped): New var.
16122 (read_key_sequence): Compute remapping in the right buffer.
16123 (command_loop_1): Use read_key_sequence's remapping directly.
16125 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16127 * dired.c (file_name_completion): Don't expand file name.
16128 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16129 before checking file name handler.
16131 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16132 they've been requested explicitly (bug#9591).
16134 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16136 * keymap.c (Fsingle_key_description): Use make_specified_string
16137 instead of build_string to build string from push_key_description.
16140 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16142 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16143 This fixes a Y2038 bug on 64-bit hosts.
16144 * buffer.c (reset_buffer):
16145 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16146 (Fclear_buffer_auto_save_failure):
16147 Use 0, not -1, to represent an unset failure time, since time_t
16148 might not be signed.
16150 Remove dependency on glibc malloc internals.
16151 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16152 Move back here from lisp.h, but with their new implementations.
16153 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16154 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16155 * charset.c (charset_table_init): New static var.
16156 (syms_of_charset): Use it instead of xmalloc. This removes a
16157 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16158 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16159 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16160 Move back to alloc.c.
16161 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16162 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16164 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16166 * nsterm.m (windowDidResize): Call x_set_window_size only when
16167 ns_in_resize is true. Otherwise set pixelwidth/height and
16168 call change_frame_size (Bug#9628).
16170 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16172 Port --enable-checking=all to Fedora 14 x86-64.
16173 * charset.c (syms_of_charset): Also account for glibc malloc's
16174 internal overhead when calculating the initial malloc maximum.
16176 Port --enable-checking=all to Fedora 14 x86.
16177 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16179 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16180 (overrun_check_realloc, overrun_check_free):
16181 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16182 That way, xmalloc returns a properly-aligned pointer even if
16183 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16184 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16185 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16186 into account when calculating the initial malloc maximum.
16187 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16188 Move here from alloc.c, so that charset.c can use it too.
16189 Properly align; the old code wasn't right for common 32-bit hosts
16190 when configured with --enable-checking=all.
16191 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16192 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16194 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16196 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16199 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16201 * xdisp.c (compute_display_string_end): If there's no display
16202 string at CHARPOS, return -1.
16204 * bidi.c (bidi_fetch_char): When compute_display_string_end
16205 returns a negative value, treat the character as a normal
16206 character not covered by a display string. (Bug#9624)
16208 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16210 * lread.c (Fread_from_string): Fix typo in docstring.
16212 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16214 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16215 newline, reseat the iterator instead of bidi-iterating there one
16216 character at a time. (Bug#9610)
16217 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16218 TO_CHARPOS if the bidi iterator is at base embedding level.
16220 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16222 * lread.c (readevalloop): Use correct code for NBSP.
16223 (read1): Likewise. (Bug#9608)
16225 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16227 * dbusbind.c (Fdbus_register_signal): When service is not
16228 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16230 2011-09-25 Glenn Morris <rgm@gnu.org>
16232 * buffer.c (truncate-lines): Doc fix.
16234 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16236 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16237 (Fset_window_next_buffers): Doc fix.
16239 2011-09-24 Glenn Morris <rgm@gnu.org>
16241 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16243 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16245 Fix minor problems found by static checking.
16246 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16247 * indent.c (Fvertical_motion): Fix == vs = typo.
16249 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16251 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16252 Default value is now t. Doc fix.
16254 * indent.c (Fvertical_motion): Compute and apply the overshoot
16255 logic when moving up, not only when moving down. Fix the
16256 confusing name and values of the it_overshoot_expected variable;
16257 logic changes accordingly. (Bug#9254) (Bug#9549)
16259 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16260 CHARPOS is covered by a display string which includes newlines.
16261 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16262 is covered by a display string with embedded newlines.
16264 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16266 * dbusbind.c (Fdbus_register_signal): Add match rule to
16267 Vdbus_registered_objects_table. (Bug#9581)
16268 (Fdbus_register_method, Vdbus_registered_objects_table):
16271 2011-09-24 Jim Meyering <meyering@redhat.com>
16273 do not ignore write error for any output size
16274 The previous change was incomplete.
16275 While it makes emacs --batch detect the vast majority of stdout
16276 write failures, errors were still ignored whenever the output size is
16277 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16278 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16279 && echo FAIL: ignored write error
16280 FAIL: ignored write error
16281 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16282 && echo FAIL: ignored write error
16283 FAIL: ignored write error
16284 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16286 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16288 * emacs.c (Fkill_emacs): In noninteractive mode exit
16289 non-successfully if a write error occurred on stdout. (Bug#9574)
16291 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16293 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16296 * dispextern.h (struct it): Update the comment documenting what
16299 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16301 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16302 a display string, extend search for cursor position to end of row.
16303 (find_row_edges): If the row ends in a newline from a display
16304 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16305 Handle the case of a display string with multiple newlines.
16306 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16307 non-empty line. Fixes confusing cursor motion with arrow keys at
16308 the beginning of a line that starts with whitespace.
16310 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16312 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16315 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16317 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16318 boolean (Bug#9154).
16320 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16322 * xdisp.c (display_line): Record maximum and minimum buffer
16323 positions even if no glyphs were produced (e.g., by a zero-width
16324 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16325 buffer positions that will be removed from the glyph row because
16327 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16328 column is beyond frame width: don't subtract 1 "pixel" when
16329 computing width of the stretch.
16330 (reseat_at_next_visible_line_start): Undo the change made on
16331 2011-09-17 that saved paragraph information and restored it after
16332 the call to `reseat'. (Bug#9545)
16334 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16336 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16337 and turn window cursor on if cleared (Bug#9415).
16339 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16341 * search.c (boyer_moore): Take unibyte characters from pattern
16342 literally. (Bug#9458)
16344 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16346 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16348 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16350 Fix minor problem found by static checking.
16351 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16352 initialized, to pacify gcc -Wuninitialized.
16354 * fileio.c: Report proper errno when syscall falls.
16355 (Finsert_file_contents): Save and restore errno,
16356 so that report_file_error outputs the correct diagnostic.
16357 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16359 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16361 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16363 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16365 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16366 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16368 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16370 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16371 about the current paragraph and restore it after the call to reseat.
16373 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16374 (bidi_find_paragraph_start): Search back for paragraph beginning
16375 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16376 (bidi_move_to_visually_next): Only trigger paragraph-related
16377 computations when the last character is a newline or at EOB, not
16378 just any NEUTRAL_B. (Bug#9470)
16380 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16381 truncated lines if point is covered by a display string. (Bug#9524)
16383 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16385 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16386 (cons_to_x_long): New function.
16387 (lisp_data_to_selection_data): Use it. Correct the test for
16388 short-versus-long data; it was negated. Break out of vector
16389 loop, for efficiency, when a long datum is discovered.
16391 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16393 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16395 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16397 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16398 GCC PR/17406) by declaring this function with external scope.
16400 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16402 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

16405 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16407 * editfns.c (Fformat): Correctly handle text properties on "%%".
16409 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16411 * xterm.c (x_draw_composite_glyph_string_foreground):
16412 * w32term.c (x_draw_composite_glyph_string_foreground):
16413 * term.c (encode_terminal_code):
16414 * composite.c (composition_update_it, get_composition_id):
16415 * xdisp.c (get_next_display_element)
16416 (fill_composite_glyph_string): Add comments about special meaning
16417 of TAB characters in a composition.
16419 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16421 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16422 This occurs when processing a multibyte format.
16423 Problem reported by Wolfgang Jenker.
16425 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16427 * xdisp.c (try_cursor_movement): Only check for exact match if
16428 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16430 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16432 Remove unused external symbols.
16433 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16434 * xdisp.c (calc_pixel_width_or_height): Now static.
16435 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16436 * indent.c (check_display_width):
16437 * w32term.c: Fix comment to match code.
16438 * xterm.c, xterm.h (x_catching_errors): Remove.
16440 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16442 * xselect.c: Use signed conversions more consistently (Bug#9498).
16443 (selection_data_to_lisp_data): Assume incoming selection data are
16444 signed integers, not unsigned. This is to be consistent with
16445 outgoing selection data, which was modified to use signed integers
16446 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16447 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16448 expects long, not unsigned long.
16450 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16452 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16453 computation of loop end. Reported by Johan Bockgård
16456 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16458 * frame.c (Fother_visible_frames_p): Function deleted.
16460 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16462 * indent.c (compute_motion): Process display vector front to back
16463 rather than the other way around. (Bug#2496)
16465 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16467 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16469 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16471 * minibuf.c (Fread_from_minibuffer): Doc fix.
16473 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16475 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16476 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16478 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16480 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16481 value for non-existent files.
16483 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16485 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16486 set its "size" to -1. This will set the modtime_size field of
16487 the corresponding buffer to -1, which is what
16488 verify-visited-file-modtime expects for files that do not exist.
16491 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16493 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16495 * lisp.h: ... from here. push_key_description is no longer
16496 defined in keyboard.c, so its declaration should not be in
16497 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16498 logically belongs with push_key_description.
16500 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16502 * buffer.h: Include <sys/types.h> instead of <time.h>.
16503 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16504 Problem reported by Herbert J. Skuhra.
16506 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16508 * xml.c (parse_region): Make the parsing work for
16509 non-comment-starting XML files again (bug#9144).
16511 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16513 * image.c (gif_load): Fix calculation of bottom and right corner.
16516 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16518 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16519 redisplay in small windows.
16521 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16523 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16525 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16527 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16528 Operate on live windows only.
16530 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16532 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16534 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16536 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16537 only under bidi iteration.
16539 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16541 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16543 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16545 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16546 Without this fix, the command to link temacs failed due to an
16547 undefined symbol __builtin_isnan. This is because
16548 /usr/include/iso/math_c99.h #defines isnan(x) to
16549 __builtin_isnan(x), but the bundled gcc, which identifies itself
16550 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16552 * floatfns.c (isnan): #undef, and then #define to a clone of
16554 (Fisnan): Always define, since it's always available now.
16555 (syms_of_floatfns): Always define isnan at the Lisp level.
16557 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16559 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16561 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16563 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16564 The previous code assumed that file offsets (off_t values) fit in
16565 EMACS_INT variables, which is not true on typical 32-bit hosts.
16566 The code messed up by falsely reporting buffer overflow in cases
16567 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16568 when "big" contains more than 2**29 bytes, even though this
16569 inserts just one byte and does not overflow the buffer.
16570 (Finsert_file_contents): Store file offsets as off_t
16571 values, not as EMACS_INT values. Check for overflow when
16572 converting between EMACS_INT and off_t. When checking for
16573 buffer overflow or for overlap, take the offsets into account.
16574 Don't use EMACS_INT for small values where int suffices.
16575 When checking for overlap, fix a typo: ZV was used where
16576 ZV_BYTE was intended.
16577 (Fwrite_region): Don't assume off_t fits into 'long'.
16578 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16580 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16582 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16584 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16586 sprintf-related integer and memory overflow issues (Bug#9412).
16588 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16589 (esprintf, exprintf, evxprintf): New functions.
16590 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16591 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16592 (modify_event_symbol): Do not assume that the length of
16593 name_alist_or_stem is safe to alloca and fits in int.
16594 (Fexecute_extended_command): Likewise for function name and binding.
16595 (Frecursion_depth): Wrap around reliably on integer overflow.
16596 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16597 since some callers pass EMACS_INT values.
16598 (Fsingle_key_description): Don't crash if symbol name contains more
16599 than MAX_ALLOCA bytes.
16600 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16601 (get_minibuffer): Arg is now EMACS_INT, not int.
16602 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16603 (esprintf, exprintf, evxprintf): New decls.
16604 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16606 * dbusbind.c (signature_cat): New function.
16607 (xd_signature, Fdbus_register_signal):
16608 Do not overrun buffer; instead, report string overflow.
16610 * dispnew.c (add_window_display_history): Don't overrun buffer.
16611 Truncate instead; this is OK since it's just a log.
16613 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16614 even if the time zone offset is outlandishly large.
16615 Don't mishandle offset == INT_MIN.
16617 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16618 when creating daemon; the previous buffer-overflow check was incorrect.
16620 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16621 which has the guts of the old verror function.
16623 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16624 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16626 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16627 (font_unparse_xlfd): Don't blindly alloca long strings.
16628 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16629 fits in int, when using sprintf. Use single snprintf to count
16630 length of string rather than counting it via multiple sprintfs;
16631 that's simpler and more reliable.
16632 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16633 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16634 sprintf, in case result does not fit in int.
16636 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16637 (fontset_from_font): Print it.
16639 * frame.c (tty_frame_count): Now printmax_t, not int.
16640 (make_terminal_frame, set_term_frame_name): Print it.
16641 (x_report_frame_params): In X, window IDs are unsigned long,
16642 not signed long, so print them as unsigned.
16643 (validate_x_resource_name): Check for implausibly long names,
16644 and don't assume name length fits in 'int'.
16645 (x_get_resource_string): Don't blindly alloca invocation name;
16646 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16649 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16650 (xg_check_special_colors, xg_set_geometry):
16651 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16653 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16654 Use esprintf, not sprintf, in case result does not fit in int.
16656 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16657 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16658 it as a large positive number.
16659 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16660 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16662 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16663 in case result does not fit in int.
16665 * print.c (float_to_string): Detect width overflow more reliably.
16666 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16667 buffer overrun. Don't assume list length fits in 'int'. Treat
16668 print length of 0 as 0, not as infinity; to be consistent with other
16669 uses of print length in this function. Don't overflow print length
16670 index. Don't assume hash table size fits in 'long', or that
16671 vectorlike size fits in 'unsigned long'.
16673 * process.c (make_process): Use printmax_t, not int, to format
16674 process-name gensyms.
16676 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16678 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16679 to avoid potential buffer overrun.
16681 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16682 if X resource line is longer than 512 bytes.
16684 * xfns.c (x_window): Make sprintf buffer a bit bigger
16685 to avoid potential buffer overrun.
16687 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16689 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16691 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16693 Integer overflow fixes for scrolling, etc.
16694 Without these, Emacs silently mishandles large integers sometimes.
16695 For example, "C-u 4294967297 M-x recenter" was treated as if
16696 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16698 * xdisp.c (try_window_id): Check Emacs fixnum range before
16699 converting to 'int'.
16701 * window.c (window_scroll_line_based, Frecenter):
16702 Check that an Emacs fixnum is in range before assigning it to 'int'.
16703 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16704 values converted from Emacs fixnums.
16705 (Frecenter): Don't wrap around a line count if it is out of 'int'
16706 range; instead, treat it as an extreme value.
16707 (Fset_window_configuration, compare_window_configurations):
16708 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16710 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16711 that can exceed INT_MAX. Check that EMACS_INT value is in range
16712 before assigning it to the (possibly-narrower) index.
16713 (match_limit): Don't assume that a fixnum can fit in 'int'.
16715 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16718 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16719 (Fvertical_motion): Don't wrap around LINES values that don't fit
16720 in 'int'. Instead, treat them as extreme values. This is good
16721 enough for windows, which can't have more than INT_MAX lines anyway.
16723 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16725 * Require libxml/parser.h to avoid compilation warning.
16727 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16729 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16730 since this reportedly can destroy thread storage.
16732 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16734 * syntax.c (find_defun_start): Update all cache variables if
16735 exiting early (Bug#9401).
16737 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16739 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16741 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16742 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16743 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16745 * term.c (tty_append_glyph): New function.
16746 (produce_stretch_glyph): Static function and its prototype deleted.
16748 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16751 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16753 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16754 when checking :margin (Bug#9390).
16755 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16756 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16757 so that the name doesn't mislead. All uses changed.
16759 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16761 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16764 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16766 * xdisp.c (move_it_to): Don't bail out early when reaching
16767 position beyond to_charpos, if we are scanning backwards.
16768 (move_it_vertically_backward): When DY == 0, make sure we get to
16769 the first character in the line after the newline.
16771 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16773 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16774 (ccl_driver): Do not generate an out-of-range pointer.
16775 (Fccl_execute_on_string): Remove unnecessary check for
16776 integer overflow, noted by Stefan Monnier in
16777 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16778 Remove a FIXME that didn't need fixing.
16779 Simplify the newly-introduced buffer reallocation code.
16781 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16783 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16785 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16787 Integer and memory overflow issues (Bug#9196).
16789 * doc.c (get_doc_string): Rework so that
16790 get_doc_string_buffer_size is the actual buffer size, rather than
16791 being 1 less than the actual buffer size; this makes xpalloc more
16794 * image.c (x_allocate_bitmap_record, cache_image):
16795 * xselect.c (Fx_register_dnd_atom):
16796 Simplify previous changes by using xpalloc.
16798 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16799 since either will do and ptrdiff_t is convenient with xpalloc.
16801 * charset.c (charset_table_size)
16802 (struct charset_sort_data.priority): Now ptrdiff_t.
16803 (charset_compare): Don't overflow if priorities differ greatly.
16804 (Fsort_charsets): Don't assume list length fits in int.
16805 Check for size-calculation overflow when allocating sort data.
16806 (syms_of_charset): Allocate an initial charset table that is
16807 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16809 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16811 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16812 The actual value is always <= INT_MAX, and leaving it unsigned made
16813 overflow checking harder.
16815 * dispextern.h (struct glyph_matrix.rows_allocated)
16816 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16817 with xpalloc. The values are still always <= INT_MAX.
16819 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16821 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16822 (SAFE_NALLOCA): New macro.
16824 * region-cache.c (struct boundary.pos, find_cache_boundary)
16825 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16826 (set_cache_region, invalidate_region_cache)
16827 (revalidate_region_cache, know_region_cache, region_cache_forward)
16828 (region_cache_backward, pp_cache):
16829 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16830 so that ptrdiff_t * can be passed to xpalloc.
16831 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16832 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16833 (pp_cache): Don't assume cache_len fits in int.
16834 * region-cache.h: Adjust extern decls to match.
16836 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16837 EMACS_INT, since either will do, for xpalloc.
16839 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16840 (xnmalloc, xnrealloc, xpalloc): New functions.
16842 * bidi.c (bidi_shelve_header_size): New constant.
16843 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16844 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16846 * bidi.c (bidi_cache_shrink):
16847 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16849 Don't update size of array until after memory allocation succeeds,
16850 because xmalloc/xrealloc may not return.
16851 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16852 now that we have proper integer overflow checking.
16853 (record_overlay_string, overlay_strings): Catch overflows when
16854 calculating size of overlay_str_buf.
16856 * callproc.c (Fcall_process): Check for size overflow when
16857 calculating size of args2.
16858 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16859 Normally we prefer signed values, but sticking with ptrdiff_t would
16860 require adding more-complicated checks.
16862 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16863 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16864 Redo buffer-overflow calculations to avoid integer overflow.
16865 Add a FIXME comment where memory seems to be over-allocated.
16867 * character.c (Fstring): Check for size-calculation overflow.
16869 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16870 unnecessary integer overflow. Check for size overflow.
16871 (encode_coding_object): Don't update size until xmalloc succeeds.
16873 * composite.c (get_composition_id): Check for overflow in glyph
16874 length calculations.
16876 Integer and memory overflow fixes for display code.
16877 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16878 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16879 (scrolling_window): Check for overflow in size calculations.
16880 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16881 Don't assume glyph table len fits in int.
16882 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16883 (row_table_size): Now ptrdiff_t, not int.
16884 (scrolling_window): Avoid overflow in size calculations.
16885 Don't update size until allocation succeeds.
16886 * fns.c (concat): Check for overflow in size calculations.
16887 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16888 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16889 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16891 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16892 (get_doc_string): Check for size calculation overflow.
16893 Don't update size until allocation succeeds.
16894 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16895 EMACS_INT, where ptrdiff_t will do.
16896 (Fsubstitute_command_keys): Check for string overflow.
16898 * editfns.c (set_time_zone_rule): Don't assume environment length
16900 (message_length): Now ptrdiff_t, not int.

16902 Don't assume message length fits in int.
16903 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16905 * emacs.c (main): Do not reallocate argv, since there is a null at
16906 the end that can be overwritten, and this way there's no need to
16907 worry about size-calculation overflow.
16908 (sort_args): Check for size-calculation overflow.

16916 Check for integer overflow.
16917 (x_set_alpha): Do not assume XINT fits in int.
16919 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16920 This is for the members text_lines, text_cols, total_lines, total_cols,
16921 where the system imposes an 'int' limit.
16923 * fringe.c (Fdefine_fringe_bitmap):
16924 Don't update size until alloc works.

16930 Check for size-calculation overflow.
16931 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16932 do, as we prefer signed integers.

16939 * gtkutil.h: Change prototypes to match the above.
16941 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

16988 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16989 for command line length. Do not attempt to address one before the
16990 beginning of an array, as that's not portable.
16992 * term.c (max_frame_lines): Remove; unused.

17019 (Finternal_make_lisp_face, cache_face):
17020 Check for size calculation overflow.
17021 (cache_face): Treat size calculation overflows as if they were
17022 memory exhaustion (the usual treatment), rather than aborting.
17024 * xfns.c (x_encode_text, x_set_name_internal)
17025 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17026 sizes, since they can exceed INT_MAX in size. Check for size
17027 calculation overflow.

17030 (xg_select): Check for size calculation overflow.
17031 Don't update size until alloc done.
17033 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17034 as sprintf is limited to int lengths.
17036 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17037 (X_LONG_MIN): New macros.
17038 Use them to make the following changes clearer.
17039 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17040 This change doesn't affect the value now, but it may help remind
17041 future maintainers not to raise the value too much later.
17042 (SELECTION_QUANTUM): Remove, replacing with ...
17043 (selection_quantum): ... new function, which avoids overflow.
17045 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17046 assumption that selection length fits in 'int'.
17047 (x_reply_selection_request, x_handle_selection_request)
17048 (x_get_window_property, receive_incremental_selection)
17049 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

17054 Redo calculations to avoid overflow.
17055 (x_reply_selection_request): When sending hint, ceiling it at

17059 (lisp_data_to_selection_data, x_property_data_to_lisp):
17060 Check for size-calculation overflow.
17061 (x_get_window_property, receive_incremental_selection)

17063 Don't store size until memory allocation succeeds.
17064 (x_get_window_property): Plug memory leak on memory exhaustion.
17065 Don't double-block input; malloc is safe here. Don't assume 2**34
17066 - 4 fits in unsigned long. Add an xassert to check
17067 XGetWindowProperty overflow. Be more careful about overflow
17068 calculations, and distinguish size from memory overflow better.
17069 (receive_incremental_selection): When tracing, don't assume
17070 unsigned int is less than INT_MAX.
17071 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17074 in the range -65535 through -1 fit in an X unsigned short.
17075 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17076 result parameters unless successful. Rely on cons_to_unsigned
17077 to report problems with elements; the old code wasn't right anyway.
17078 (x_check_property_data): Check for int overflow; we cannot use
17079 a wider type due to X limits.
17080 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17112 * lisp.h (hash_lookup, hash_put):
17113 * minibuf.c (Ftest_completion):
17114 Use ptrdiff_t for hash table indexes, not int (which is too
17115 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17116 32-bit --with-wide-int hosts).
17118 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17119 Add a FIXME comment about memory leaks.
17120 (syms_of_charset): Don't assume xmalloc returns.

17127 with outlandish widths.
17128 * character.h (sanitize_tab_width): Rename from sanitize_width,
17129 now that we have two such functions. All uses changed.

17147 * xterm.c: Don't go over XClientMessageEvent limit.
17148 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17149 (x_send_scroll_bar_event): Likewise. Check that the size does not
17150 exceed limits imposed by XClientMessageEvent, as well as the usual
17151 ptrdiff_t and size_t limits.
17153 * keyboard.c: Overflow, signedness and related fixes.
17154 (make_lispy_movement): Use same integer type in forward decl
17155 that is used in the definition.
17156 (read_key_sequence, keyremap_step):
17157 Change bufsize argument back to int, undoing my 2011-03-30 change.
17158 We prefer signed types, and int is wide enough here.
17159 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17160 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17161 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17162 length, not size_t. Use ptrdiff_t for index, not int.
17163 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17164 possibility of integer overflow.
17166 Overflow, signedness and related fixes for images.

17192 Prefer int to unsigned where either will do.
17193 (tiff_handler): New function, combining the cores of the
17194 old tiff_error_handler and tiff_warning_handler.
17195 This function is rewritten to use vsnprintf and thereby avoid
17196 stack buffer overflows. It uses only the features of vsnprintf
17197 that are common to both POSIX and native Microsoft.
17198 (tiff_error_handler, tiff_warning_handler): Use it.
17199 (tiff_load, gif_load, imagemagick_load_image):
17200 Don't assume :index value fits in 'int'.
17201 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17202 (imagemagick_load_image): Check that crop parameters fit into
17203 the integer types that MagickCropImage accepts. Don't assume
17204 Vimagemagick_render_type has a nonnegative value. Don't assume
17205 size_t fits in 'long'.
17206 (gs_load): Use printmax_t to print the widest integers possible.

17219 handle_single_display_spec, not just 1 or zero.
17220 (handle_single_display_spec): If the display spec is of the form
17221 `(space ...)', and specifies display in the text area, return 2
17223 (try_cursor_movement): Check for the need to scroll more
17224 accurately, and prefer exact match for point under bidi.
17225 Don't advance `row' beyond the last row of the window.

17243 buffers, return left-to-right.
17244 (set_cursor_from_row): Consider candidate row a win if its glyph
17245 represents a newline and point is on that newline. Fixes cursor
17246 positioning on the newline at EOL of R2L text within L2R
17247 paragraph, and vice versa.
17248 (try_cursor_movement): Check continued rows, in addition to
17249 continuation rows. Fixes unwarranted scroll when point enters a
17250 continued line of R2L text within an L2R paragraph, or vice versa.
17251 (cursor_row_p): Consider the case of point being equal to
17252 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17253 from the end of a short line to the beginning of a continued line
17254 of R2L text within L2R paragraph.
17255 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

17278 * xdisp.c (redisplay_window): When computing centering_position,
17279 account for the height of the header line. (Bug#8874)
17281 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17282 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17283 candidate is selected by the mouse, and that candidate has a
17284 composed character under the mouse.
17286 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17287 coordinates reported by pos-visible-in-window-p for a composed
17288 character in column zero.
17290 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

17294 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17296 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17297 consider it a hit if to_charpos is anywhere in the range of the
17298 composed buffer positions.
17300 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17302 * image.c (gif_load): Don't assume that each subimage has the same
17303 dimensions as the base image. Handle disposal method that is
17304 "undefined" by the gif spec (Bug#9335).
17306 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17308 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17313 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17314 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17315 from an Org mode buffer to a Speedbar frame.
17317 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17318 a composition, take its buffer position from IT->cmp_it.charpos.
17319 Fixes cursor positioning at the beginning of a line that begins
17320 with a composed character.
17322 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17324 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17325 character bidirectional type, use STRONG_L instead. Fixes crashes
17326 in a buffer produced by `describe-categories'.
17328 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17329 members before the level stack, so they would be saved and
17330 restored when copying iterator state. Fixes incorrect reordering
17331 around TABs covered by display properties.
17333 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17335 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
17337 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
17339 * eval.c (internal_condition_case, internal_condition_case_1)
17340 (internal_condition_case_2, internal_condition_case_n):
17341 Remove unnecessary aborts (Bug#9081).
17343 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17345 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17346 has no `load' handler, try opening the file locally. (Bug#9311)
17348 2011-08-16 Ken Brown <kbrown@cornell.edu>
17350 * gmalloc.c: Expand comment.
17352 2011-08-16 Eli Zaretskii <eliz@gnu.org>
17354 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17355 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
17357 2011-08-16 Ken Brown <kbrown@cornell.edu>
17359 Fix memory allocation problems in Cygwin build (Bug#9273).
17361 * unexcw.c ( __malloc_initialized): Declare external variable.

17364 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
17366 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17368 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17369 in the static heap.
17370 [CYGWIN] (special_realloc): New function.
17371 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
17372 requests to realloc storage in the static heap.

17383 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
17385 * dispextern.h: Fix a typo in the comment to bidi_type_t.
17387 * chartab.c: Improve commentary for the uniprop_table API.
17389 * bidi.c (bidi_paragraph_init): Support zero value of
17390 bidi_ignore_explicit_marks_for_paragraph_level.
17391 (bidi_initialize): Use uniprop_table instead of including
17392 biditype.h and bidimirror.h.
17394 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
17395 coordinates of the iterator when restoring from ppos_it.
17398 2011-08-14 Kenichi Handa <handa@m17n.org>
17400 * process.c (create_process): Call setup_process_coding_systems
17401 after the pid of the process is set to -1 (Bug#8162).
17403 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17405 * xdisp.c (move_it_in_display_line_to): Don't invoke
17406 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17407 ppos_it. Fixes vertical cursor motion when line beginning is
17408 covered by an image. (Bug#9296)
17410 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17412 * nsterm.h (ns_run_ascript): Declare.
17413 (NSAPP_DATA2_RUNASSCRIPT): Define.
17415 * nsfns.m (as_script, as_result, as_status): New static variables.
17416 (ns_run_ascript): New function.
17417 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17418 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17419 the event loop. Get status from as_status (Bug#7276).
17421 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17422 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17423 the event loop (Bug#7276).
17425 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17427 * gnutls.c (QCgnutls_bootprop_priority)
17428 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17429 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17430 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17431 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17432 (QCgnutls_bootprop_verify_hostname_error)
17433 (QCgnutls_bootprop_callbacks_verify): Rename from
17434 Qgnutls_bootprop_..., all uses changed.

17446 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17448 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17449 (Fnetwork_interface_list): Allocate in increments of bytes instead
17450 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17451 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17453 (struct ifflag_def): notrailers is smart on OSX.
17454 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17455 Get hardware address with getifaddrs if available.
17457 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17459 * xdisp.c (iterate_out_of_display_property): xassert that
17460 IT->position is set to within IT->object's boundaries. Break from
17461 the loop as soon as EOB is reached; avoids infloops in redisplay
17462 when IT->position is set up wrongly due to some bug.
17463 Set IT->current to match the bidi iterator unconditionally.
17464 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17465 entry. Force push_it to save on the stack the current
17466 buffer/string position, to be restored by pop_it. Fix flags in
17467 the iterator structure wrt the object coming from a display
17468 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17469 properties. (Bug#9284)
17471 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17473 * fontset.c (fontset_get_font_group): Add proper type checks.
17476 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17478 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17479 and LC_VERSION_MIN_MACOSX.
17480 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17481 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17483 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17485 * xdisp.c (forward_to_next_line_start): Allow to use the
17486 no-display-properties-and-no-overlays under bidi display.
17487 Set disp_pos in the bidi iterator to avoid searches for display
17488 properties and overlays.
17490 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17492 * editfns.c (Fset_time_zone_rule): Document relationship with the
17495 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17496 the font entity extracted from the cache (Bug#8109).
17498 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17500 * composite.c (autocmp_chars): Don't reset point. That is done by
17501 restore_point_unwind (Bug#5984).
17503 2011-08-07 Juri Linkov <juri@jurta.org>
17505 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17506 to show the arg `TIME' instead of `TIMEVAL'.
17508 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17510 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17511 display property strides EOL and includes a newline, as in
17512 longlines-mode. (Bug#9254)
17513 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17514 word-wrap under bidirectional display. (Bug#9224)
17516 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17517 is non-zero, even if the data buffer is NULL. Fixes a crash in
17518 vertical-motion with longlines-mode. (Bug#9254)
17520 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17522 * bidi.c <bidi_cache_total_alloc>: Now static.
17523 (bidi_initialize): Initialize bidi_cache_total_alloc.
17525 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17528 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17529 amount allocated this far in `bidi_cache_total_alloc'.
17530 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17531 non-zero, only free the data buffer without restoring the cache
17532 contents. All callers changed.
17534 * dispextern.h (bidi_unshelve_cache): Update prototype.
17536 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17537 (move_it_in_display_line, move_it_to)
17538 (move_it_vertically_backward, move_it_by_lines): Replace the call
17539 to xfree to an equivalent call to bidi_unshelve_cache.
17540 (move_it_in_display_line_to): Fix logic of returning
17541 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17543 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17545 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17546 came from a string character with a `cursor' property. (Bug#9229)
17548 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17550 * Makefile.in (LIB_PTHREAD): New variable.
17551 (LIBES): Add LIB_PTHREAD (Bug#9216).
17553 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17554 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17556 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17558 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17560 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17562 * xterm.c (x_find_topmost_parent): New function.
17563 (x_set_frame_alpha): Find topmost parent window with
17564 x_find_topmost_parent and set the property there also (bug#9181).
17565 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17567 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17569 * callproc.c (Fcall_process): Avoid vfork clobbering
17570 the local vars buffer, coding_systems, current_dir.
17572 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17574 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17576 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17578 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17579 so that it is not optimized away.
17581 * xdisp.c (compute_display_string_pos): Remove unused local.
17583 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17585 Fix slow cursor motion and scrolling in large buffers with
17586 selective display, like Org Mode buffers. (Bug#9218)
17588 * dispextern.h (struct bidi_it): New member disp_prop_p.
17590 * xdisp.c: Remove one-slot cache of display string positions.
17591 (compute_display_string_pos): Accept an additional argument
17592 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17593 for a display string or property. If found, set DISP_PROP_P
17596 * bidi.c (bidi_fetch_char): Accept an additional argument
17597 DISP_PROP_P, and pass it to compute_display_string_pos.
17598 Only handle text covered by a display string if DISP_PROP_P is returned
17599 non-zero. All callers of bidi_fetch_char changed.
17601 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17603 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17605 2010-12-03 Don March <don@ohspite.net>
17607 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17608 last character M-[char] is translated to ESC [char] (bug#7541).
17610 2011-08-02 Kenichi Handa <handa@m17n.org>
17612 * lisp.h (uniprop_table): Extern it.
17614 * chartab.c (uniprop_table): Make it non-static.
17616 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17618 * xdisp.c (forward_to_next_line_start): Accept additional argument
17619 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17621 (reseat_at_next_visible_line_start): Use the bidi iterator state
17622 returned by forward_to_next_line_start to restore the state of
17623 it->bidi_it after backing up to previous newline. (Bug#9212)
17625 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17627 * regex.c (re_comp): Protoize.
17628 (re_exec): Fix return type.
17629 (regexec): Fix type of `ret'. (Bug#9203)
17631 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17633 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17634 This is needed if max-image-size is a floating-point number.
17636 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17638 * print.c (print_object): Print empty symbol as ##.
17640 * lread.c (read1): Read ## as empty symbol.
17642 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17644 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17645 setting frame foreground color (Bug#9175).
17646 (x_set_background_color): Likewise.
17648 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17649 contents (Bug#9176).
17650 (EmacsTooltip -init): Remove bezels and add shadows to
17653 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17654 or scroll bar (Bug#8470).
17656 * nsfont.m (nsfont_open): Remove assignment to voffset and
17657 unnecessary vars hshink, expand, hd, full_height, min_height.
17658 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17660 * nsterm.h (nsfont_info): Remove voffset field.
17662 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17664 Implement strike-through and overline on NextStep (Bug#8863).
17666 * nsfont.m (nsfont_open): Use underline position provided by font,
17667 instead of hard-coded value of 2.
17668 (nsfont_draw): Call ns_draw_text_decoration instead.
17670 * nsterm.h: Add declaration for ns_draw_text_decoration.
17672 * nsterm.m (ns_draw_text_decoration): New function for drawing
17673 underline, overline, and strike-through.
17674 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17675 ns_draw_text_decoration. Change treatment of cursor drawing to
17676 accommodate underlining, etc.
17678 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17680 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17683 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17685 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17686 Without this fix, if a signal arrives just after memory fills up,
17687 'malloc' might be invoked reentrantly.
17689 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17690 In other words, assume that every image size is allowed, on non-X
17691 hosts. This assumption is probably wrong, but it lets Emacs compile.
17693 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17695 * regex.c (re_iswctype): Convert return values to boolean.
17697 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17699 * xdisp.c (compute_display_string_pos): Don't use cached display
17700 string position if the buffer had its restriction changed.
17703 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17705 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17707 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17709 Integer signedness and overflow and related fixes. (Bug#9079)
17711 * bidi.c: Integer size and overflow fixes.
17712 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17713 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17714 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17715 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17716 (bidi_find_other_level_edge):
17717 Use ptrdiff_t instead of EMACS_INT where either will do.
17718 This works better on 32-bit hosts configured --with-wide-int.
17719 (bidi_cache_ensure_space): Check for size-calculation overflow.
17720 Use % rather than repeated addition, for better worst-case speed.
17721 Don't set bidi_cache_size until after xrealloc returns, because it
17723 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17724 (bidi_cache_ensure_space): Also check that the bidi cache size
17725 does not exceed that of the largest Lisp string or buffer. See Eli
17726 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17728 * alloc.c (__malloc_size_t): Remove.
17729 All uses replaced by size_t. See Andreas Schwab's note
17730 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17732 * image.c: Improve checking for integer overflow.
17733 (check_image_size): Assume that f is nonnull, since
17734 it is always nonnull in practice. This is one less thing to
17735 worry about when checking for integer overflow later.
17736 (x_check_image_size): New function, which checks for integer
17737 overflow issues inside X.
17738 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17739 This removes the need for a memory_full check.
17740 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17741 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17742 (xbm_read_bitmap_data): Change locals back to 'int', since
17743 their values must fit in 'int'.
17744 (xpm_load_image, png_load, tiff_load):
17745 Invoke x_create_x_image_and_pixmap earlier,
17746 to avoid much needless work if the image is too large.
17747 (tiff_load): Treat overly large images as if
17748 x_create_x_image_and_pixmap failed, not as malloc failures.
17749 (gs_load): Use x_check_image_size.
17751 * gtkutil.c: Omit integer casts.
17752 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17753 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17755 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17757 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17758 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17759 would wrongly return t on a 64-bit host.
17761 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17762 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17763 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17764 and therefore cause GCC to emit a bogus diagnostic in some cases.
17766 * image.c: Integer signedness and overflow and related fixes.
17767 This is not an exhaustive set of fixes, but it's time to
17768 record what I've got.
17769 (lookup_pixel_color, check_image_size): Remove redundant decls.
17770 (check_image_size): Don't assume that arbitrary EMACS_INT values
17771 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17772 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17773 (tiff_load, imagemagick_load_image):
17774 Check for overflow in size calculations.
17775 (x_create_x_image_and_pixmap): Remove unnecessary test for
17776 xmalloc returning NULL; that can't happen.
17777 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17778 (xpm_color_bucket): Use better integer hashing function.
17779 (xpm_cache_color): Don't possibly over-allocate memory.
17780 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17781 (gif_memory_source):
17782 Use ptrdiff_t, not int or size_t, to record sizes.
17783 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17784 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17785 either works, as we prefer signed integers.
17786 (tiff_read_from_memory, tiff_write_from_memory):
17787 Return tsize_t, not size_t, since that's what the TIFF API wants.
17788 (tiff_read_from_memory): Don't fail simply because the read would
17789 go past EOF; instead, return a short read.
17790 (tiff_load): Omit no-longer-needed casts.
17791 (Fimagemagick_types): Don't assume size fits into 'int'.
17793 Improve hashing quality when configured --with-wide-int.
17794 * fns.c (hash_string): New function, taken from sxhash_string.
17795 Do not discard information about ASCII character case; this
17796 discarding is no longer needed.
17797 (sxhash-string): Use it. Change sig to match it. Caller changed.
17798 * lisp.h: Declare it.
17799 * lread.c (hash_string): Remove, since we now use fns.c's version.
17800 The fns.c version returns a wider integer if --with-wide-int is
17801 specified, so this should help the quality of the hashing a bit.
17803 * emacs.c: Integer overflow minor fix.
17804 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17805 Define only if GNU_LINUX.
17806 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17808 * dispnew.c: Integer signedness and overflow fixes.
17809 Remove unnecessary forward decls, that were a maintenance hassle.
17810 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17812 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17813 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17814 (prepare_desired_row, line_draw_cost):
17815 Use int, not unsigned, where either works.
17816 (save_current_matrix, restore_current_matrix):
17817 Use ptrdiff_t, not size_t, where either works.
17818 (init_display): Check for overflow more accurately, and without
17819 relying on undefined behavior.
17821 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17822 Remove, replacing with the new symbols in lisp.h. All uses changed.
17823 * fileio.c (make_temp_name):
17824 * filelock.c (lock_file_1, lock_file):
17825 * xdisp.c (message_dolog):
17826 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17827 Use pMd etc. instead.
17828 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17829 replacing the pWIDE etc. symbols removed from editfns.c.
17831 * keyboard.h (num_input_events): Now uintmax_t.
17832 This is (very slightly) less likely to mess up due to wraparound.
17835 * buffer.c: Integer signedness fixes.
17836 (alloc_buffer_text, enlarge_buffer_text):
17837 Use ptrdiff_t rather than size_t when either will do, as we prefer
17840 * alloc.c: Integer signedness and overflow fixes.
17841 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17842 (__malloc_size_t): Default to size_t, not to int.
17843 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17844 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17845 Prefer ptrdiff_t to size_t when either would do, as we prefer
17847 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17848 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17849 Now const. Initialize with values that are in range even if char
17851 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17852 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17853 These functions do the right thing with sizes > 2**32.
17854 (check_depth): Now ptrdiff_t, not int.
17855 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17856 Adjust to new way of storing sizes. Check for size overflow bugs
17858 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17859 slightly wrong anyway, as it missed one instance of
17860 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17861 (refill_memory_reserve): Omit needless cast to size_t.
17862 (mark_object_loop_halt): Mark as externally visible.
17864 * xselect.c: Integer signedness and overflow fixes.
17865 (Fx_register_dnd_atom, x_handle_dnd_message):
17866 Use ptrdiff_t, not size_t, since we prefer signed.
17867 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17868 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17869 x_dnd_atoms_size and x_dnd_atoms_length.
17871 * doprnt.c: Prefer signed to unsigned when either works.
17873 * doprnt.c (doprnt):
17875 * xdisp.c (vmessage):
17876 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17877 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17878 prefer signed arithmetic to avoid comparison confusion.
17879 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17880 but is a bit tricky.
17882 Assume freestanding C89 headers, string.h, stdlib.h.
17883 * data.c, doprnt.c, floatfns.c, print.c:
17884 Include float.h unconditionally.
17885 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17886 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17887 * regex.c: Likewise for stddef.h, string.h.
17888 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17889 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17890 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17891 (STDC_HEADERS): Remove obsolete defines.
17892 * sysdep.c: Include limits.h unconditionally.
17894 Assume support for memcmp, memcpy, memmove, memset.
17895 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17896 * regex.c (memcmp, memcpy):
17897 Remove; we assume C89 now.
17899 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17900 (__malloc_safe_bcopy): Remove; no longer needed.
17902 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17903 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17904 well either way, and we prefer signed to unsigned.
17906 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17908 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17909 closes the connection while we're reading (bug#9182).
17911 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17913 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17914 are specified (Bug#9168).
17916 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17918 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17919 Found by GCC static checking and --with-wide-int on a 32-bit host.
17921 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17923 * xdisp.c (compute_display_string_pos): Fix logic of caching
17924 previous display string position. Initialize cached_prev_pos to
17925 -1. Fixes slow-down at the beginning of a buffer.
17927 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17929 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17930 for attrs[LFACE_FONTSET_INDEX].
17932 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17934 * xml.c (parse_region): Remove unused local
17935 that was recently introduced.
17937 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17939 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17940 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17942 * xdisp.c (move_it_in_display_line_to): Record the best matching
17943 position for TO_CHARPOS while scanning the line, and restore it on
17944 exit if none of the characters scanned was an exact match.
17945 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17946 when exact match is impossible due to invisible text, and the
17947 lines are truncated.
17949 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17951 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17954 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17956 Fix a significant slow-down of cursor motion with C-n, C-p,
17957 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17958 auto-repeat under bidi redisplay in fontified buffers.
17959 * xdisp.c (compute_stop_pos_backwards): New function.
17960 (next_element_from_buffer): Call compute_stop_pos_backwards to
17961 find a suitable prev_stop when we find ourselves before
17963 (reseat): Don't look for prev_stop, as that could mean a very long
17965 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17966 <cached_disp_overlay_modiff>: Cache for last found display string
17968 (compute_display_string_pos): Return the cached position if asked
17969 about the same buffer in the same area of character positions, and
17970 the buffer wasn't changed since the time the display string
17971 position was cached.
17973 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17975 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17976 is an integer, which is important for empty lines. (Bug#9149)
17978 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17980 * frame.c (Fmodify_frame_parameters): In tty case, update the
17981 default face if necessary (Bug#4238).
17983 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17985 * editfns.c (Fstring_to_char): No need to explain what a character
17986 is in the docstring (Bug#6576).
17988 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17990 * xml.c (parse_region): Make sure we always return a tree.
17992 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17994 * xml.c (parse_region): If a document contains only comments,
17997 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17999 * xml.c (make_dom): Return comments, too.
18001 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18004 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18005 and the surrounding thread.
18006 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18007 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18008 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18010 * s/openbsd.h (BROKEN_SIGIO): Define.
18011 * unexelf.c (unexec) [__OpenBSD__]:
18012 Don't update the .mdebug section of the Alpha COFF symbol table.
18014 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18016 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18019 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18021 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18022 This fixes some race conditions on the permissions of any newly
18025 * alloc.c (valid_pointer_p): Use pipe, not open.
18026 This fixes some permissions issues when debugging.
18028 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18029 If fchown fails to set both uid and gid, try to set just gid,
18030 as that is sometimes allowed. Adjust the file's mode to eliminate
18031 setuid or setgid bits that are inappropriate if fchown fails.
18033 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18035 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18036 to compare Lisp_Objects.
18037 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18038 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18039 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18041 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18043 * lread.c (read_integer): Unread even EOF character.
18044 (read1): Likewise. Properly record start position of symbol.
18046 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18047 symbol character follows.
18049 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18051 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18052 This works around a problem with the previous change to Fcopy_file.
18053 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18054 and without this change, GCC might complain about discarding
18055 fchown's return value.
18057 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18059 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18061 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18063 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18065 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18067 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18068 it's used from the C level.
18070 * process.c: Use the same condition for POLL_FOR_INPUT in both
18071 keyboard.c and process.c (bug#1858).
18073 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18075 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18076 (Fgnutls_boot): Use it.
18078 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18080 * doc.c (Fsubstitute_command_keys): Revert last change.
18082 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18084 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18085 quotes the next character, and doesn't affect other longer
18086 sequences (bug#8935).
18088 * lread.c (syms_of_lread): Clarify that is isn't only
18089 `eval-buffer' and `eval-defun' that's affected by
18090 `lexical-binding' (bug#8460).
18092 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18094 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18095 bidi redisplay when a line includes both an image and is truncated.
18097 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18099 Fix minor problems found by static checking.
18100 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18101 (elsz): Now a signed constant, not a size_t var. We prefer signed
18102 types to unsigned, to avoid integer comparison confusion. Without
18103 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18104 "cannot optimize loop, the loop counter may overflow", a symptom
18106 * indent.c (Fvertical_motion): Mark locals as initialized.
18107 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18109 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18111 * search.c (Fre_search_backward): Mention `case-fold-search' in
18112 all the re_search_* functions (bug#8138).
18114 * keyboard.c (Fopen_dribble_file): Document when the file is
18117 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18119 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18122 Support bidi reordering of display and overlay strings.

18124 (compute_display_string_end): Accept additional argument STRING.
18125 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18126 (reseat_to_string): Initialize bidi_it->string.s and
18127 bidi_it->string.schars.
18128 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18129 NULL (avoids a crash in bidi_paragraph_init).
18130 Initialize itb.string.lstring.
18131 (init_iterator): Call bidi_init_it only of a valid
18132 buffer position was specified. Initialize paragraph_embedding to
18134 (reseat_to_string): Initialize the bidi iterator.
18135 (display_string): If we need to ignore text properties of
18136 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18137 original value of -1 will not work with bidi.)
18138 (compute_display_string_pos): First arg is now struct
18139 `text_pos *'; all callers changed. Support display properties on
18141 (compute_display_string_end): Support display properties on Lisp
18143 (init_iterator, reseat_1, reseat_to_string): Initialize the
18144 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18145 when iterating on a string not from display properties).
18146 (compute_display_string_pos, compute_display_string_end):
18147 Fix calculation of the object to scan. Fixes an error when using
18149 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18150 base_level_stop; instead, set base_level_stop to BEGV.
18151 Fixes crashes in vertical-motion.
18152 (next_element_from_buffer): Improve commentary for when
18153 the iterator is before prev_stop.
18154 (init_iterator): Initialize bidi_p from the default value of
18155 bidi-display-reordering, not from buffer-local value. Use the
18156 buffer-local value only if initializing for buffer iteration.
18157 (handle_invisible_prop): Support invisible properties on strings
18158 that are being bidi-reordered.
18159 (set_iterator_to_next): Support bidi reordering of C strings and
18161 (next_element_from_string): Support bidi reordering of Lisp
18163 (handle_stop_backwards): Support Lisp strings as well.
18164 (display_string): Support display of R2L glyph rows.
18165 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18166 (init_iterator): Don't initialize it->bidi_p for strings
18168 (reseat_to_string): Initialize it->bidi_p for strings here.
18169 (next_element_from_string, next_element_from_c_string)
18170 (next_element_from_buffer): Add xassert's for correspondence
18171 between IT's object being iterated and it->bidi_it.string
18173 (face_before_or_after_it_pos): Support bidi iteration.
18174 (next_element_from_c_string): Handle the case of the first string
18175 character that is not the first one in the visual order.
18176 (get_visually_first_element): New function, refactored from common
18177 parts of next_element_from_buffer, next_element_from_string, and
18178 next_element_from_c_string.
18179 (tool_bar_lines_needed, redisplay_tool_bar)
18180 (display_menu_bar): Force left-to-right direction. Add a FIXME
18181 comment for making that be controlled by a user option.
18182 (push_it, pop_it): Save and restore the state of the
18183 bidi iterator. Save and restore the bidi_p flag.
18184 (pop_it): Iterate out of display property for string iteration as
18186 (iterate_out_of_display_property): Support iteration over strings.
18187 (handle_single_display_spec): Set up it->bidi_it for iteration
18188 over a display string, and call bidi_init_it.
18189 (handle_single_display_spec, next_overlay_string)
18190 (get_overlay_strings_1, push_display_prop): Set up the bidi
18191 iterator for displaying display or overlay strings.
18192 (forward_to_next_line_start): Don't use the shortcut if
18194 (back_to_previous_visible_line_start): If handle_display_prop
18195 pushed the iterator stack, restore the internal state of the bidi
18196 iterator by calling bidi_pop_it same number of times.
18197 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18198 and we are bidi-iterating, don't decrement the iterator position;
18199 instead, set the first_elt flag in the bidi iterator, to produce
18201 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18202 (push_display_prop): xassert that we are iterating a buffer.
18203 (push_it, pop_it): Save and restore paragraph_embedding member.
18204 (handle_single_display_spec, next_overlay_string)
18205 (get_overlay_strings_1, reseat_1, reseat_to_string)
18206 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18207 correctly. Don't assume unibyte strings are not bidi-reordered.
18208 (compute_display_string_pos)
18209 (compute_display_string_end): Fix handling the case of C string.
18210 (push_it, pop_it): Save and restore from_disp_prop_p.
18211 (handle_single_display_spec, push_display_prop): Set the
18212 from_disp_prop_p flag.
18213 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
18214 (pop_it): Call iterate_out_of_display_property only if we are
18215 popping after iteration over a string that came from a display
18216 property. Fix a typo in popping stretch info. Add an assertion
18217 for verifying that the iterator position is in sync with the bidi
18219 (handle_single_display_spec, get_overlay_strings_1)
18220 (push_display_prop): Fix initialization of paragraph direction for
18221 string when that of the parent object is not yet determined.
18222 (reseat_1): Call bidi_init_it to resync the bidi
18223 iterator with IT's position. (Bug#7616)
18224 (find_row_edges): If ROW->start.pos gives position
18225 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
18226 (handle_stop, back_to_previous_visible_line_start, reseat_1):
18227 Reset the from_disp_prop_p flag.
18228 (SAVE_IT, RESTORE_IT): New macros.
18229 (pos_visible_p, face_before_or_after_it_pos)
18230 (back_to_previous_visible_line_start)

18670 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
18672 Random fixes. E.g., (random) never returned negative values.
18673 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18674 subseconds part to the entropy, as that's a bit more random.
18675 Prefer signed to unsigned, since the signedness doesn't matter and
18676 in general we prefer signed. When given a limit, use a
18677 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18678 latter isn't right if USE_2_TAGS_FOR_INTS.
18679 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18680 not 0..VALMASK. Don't discard "excess" bits that random () returns.
18682 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
18684 * textprop.c (text_property_stickiness):
18685 Obey Vtext_property_default_nonsticky.
18686 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

18692 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18693 This is more efficient than Ffile_directory_p and avoids a minor race.
18695 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18697 * buffer.c (Foverlay_put): Say what the return value is
18700 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18701 is a directory before asking whether to use the file name
18703 (barf_or_query_if_file_exists): Make the "File is a directory"
18704 error be more correct.
18706 * fns.c (Frequire): Remove the mention of the .gz files, since
18707 that's installation-specific, but keep the mention of
18708 `get-load-suffixes'.
18710 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18712 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18717 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
18718 (syms_of_gnutls): Remove duplicate DEFSYM for
18719 Qgnutls_bootprop_verify_hostname_error, an error for
18720 Qgnutls_bootprop_verify_error (which is no longer used).
18722 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18723 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18724 Also (re)move comments that are misplaced or no longer relevant.
18726 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18728 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18753 * lread.c (syms_of_lread): Mention single symbols defined by
18754 `defvar' or `defconst' (bug#7154).
18756 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18757 (Frequire): Mention get-load-suffixes.
18759 2011-07-02 Martin Rudalics <rudalics@gmx.at>

18787 (syms_of_keymap): Defsubr make-composed-keymap.
18788 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18825 * eval.c (struct backtrace): Simplify and port the data structure.
18826 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18827 signed bit field, as this assumption is not portable and it makes
18828 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18829 "char debug_on_exit : 1" as this is not portable either; instead,
18830 use the portable "unsigned int debug_on_exit : 1". Remove unused
18831 member evalargs. Remove obsolete comments about cc bombing out.
18833 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
18835 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

18901 (emacs_fixed_new): Set priv->f to argument.
18902 (emacs_fixed_get_preferred_width)
18903 (emacs_fixed_get_preferred_height): Use min_width/height from
18904 frames size_hint to set minimum and natural (Bug#8919).
18905 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18906 and use min_width/height from frames size_hint to set
18907 min_width/height (Bug#8919).

18927 Use gnulib's dup2 module instead of rolling our own.
18928 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

19000 (PRINTPREPARE, printchar, strout):
19001 Don't set size unless allocation succeeds.
19003 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19004 for sizes. Check for string overflow more accurately.

19018 (read_integer): Radix is now EMACS_INT, not int,
19019 to improve quality of diagnostics for out-of-range radices.
19020 Calculate buffer size correctly for out-of-range radices.
19021 (read1): Check for integer overflow in radices, and in
19022 read-circle numbers.
19023 (read_escape): Avoid int overflow.
19024 (Fload, openp, read_buffer_size, read1)
19025 (substitute_object_recurse, read_vector, read_list, map_obarray):
19026 Use ptrdiff_t, not int, for sizes.

19048 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19049 The following patches are for when GLYPH_DEBUG && !XASSERT.
19050 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19051 * dispnew.c (flush_stdout):
19052 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19053 Mark as externally visible.
19054 * dispnew.c (check_window_matrix_pointers): Now static.
19055 * dispnew.c (window_to_frame_vpos):
19056 * xfns.c (unwind_create_frame):

19063 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19065 (debug_method_add): Use va_list and vsprintf rather than relying
19066 on undefined behavior with wrong number of arguments.
19067 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19068 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19069 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19070 since we're not interested in debugging glyphs with old libraries.
19071 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19072 GCC 4.6.0's static checking.
19074 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

19107 (mouse_face_overlay_overlaps, Foverlays_in):
19108 Use ptrdiff_t, not int, for sizes.
19109 (overlays_at, overlays_in): Check for size-calculation overflow.
19111 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19113 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19114 (x_session_initialize): Do not assume string length fits in int.
19116 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19117 This is unlikely, but can occur if DPI is outlandish.
19119 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19120 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19122 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19123 * xrdb.c (magic_file_p, search_magic_path):
19124 Omit last arg SUFFIX; it was always 0. All callers changed.
19125 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19127 * xfont.c (xfont_match): Avoid need for strlen.
19129 * xfns.c: Don't assume strlen fits in int.
19130 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19132 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19133 not unsigned long, as we prefer signed integers. All callers changed.
19134 Detect integer overflow in repeat count.
19135 (message_dolog): Don't assume print length fits in 39 bytes.
19136 (display_mode_element): Don't assume strlen fits in int.
19138 * termcap.c: Don't assume sizes fit in int and never overflow.
19139 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19140 (gobble_line): Check for size-calculation overflow.
19142 * minibuf.c (Fread_buffer):
19143 * lread.c (intern, intern_c_string):
19144 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19145 Don't assume string length fits in int.
19147 * keyboard.c (parse_tool_bar_item):
19148 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19150 * font.c: Don't assume string length fits in int.
19151 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19152 Use ptrdiff_t, not int.
19153 (font_intern_prop): Don't assume string length fits in int.
19154 Don't assume integer property fits in fixnum.
19155 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19157 * filelock.c: Fix some buffer overrun and integer overflow issues.
19158 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19159 Reformulate so as not to need the command string.
19160 Invoke gzip -cd rather than gunzip, as it's more portable.
19161 (lock_info_type, lock_file_1, lock_file):
19162 Don't assume pid_t and time_t fit in unsigned long.
19163 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19164 (current_lock_owner): Prefer signed type for sizes.
19165 Use memcpy, not strncpy, where memcpy is what is really wanted.
19166 Don't assume (via atoi) that time_t and pid_t fit in int.
19167 Check for time_t and/or pid_t out of range, e.g., via a network share.
19168 Don't alloca where an auto var works fine.
19170 * fileio.c: Fix some integer overflow issues.
19171 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19172 Don't assume string length fits in int.
19173 (directory_file_name): Don't assume string length fits in long.
19174 (make_temp_name): Don't assume pid fits in int, or that its print
19175 length is less than 20.
19177 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19179 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19181 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19183 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19184 We prefer signed integers, even for size calculations.
19186 * emacs.c: Don't assume string length fits in 'int'.
19187 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19188 (main): Don't invoke strlen when not needed.
19190 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19191 (XD_DEBUG_MESSAGE): Don't waste a byte.
19193 * callproc.c (getenv_internal_1, getenv_internal)
19194 (Fgetenv_internal):
19195 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19197 * lread.c (invalid_syntax): Omit length argument.
19198 All uses changed. This doesn't fix a bug, but it simplifies the
19199 code away from its former Hollerith-constant appearance, and it's
19200 one less 'int' to worry about when looking at integer-overflow issues.
19201 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19203 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19204 This didn't break anything, but it didn't help either.
19205 It's confusing to put a bogus integer in a place where the actual
19206 value does not matter.
19207 (LIST_END_P): Remove unused macro and its bogus comment.
19208 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19210 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19211 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19213 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19214 We prefer signed types, and the value cannot exceed the EMACS_INT
19215 range anyway (because otherwise the length would not be representable).
19216 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19217 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19218 This avoids a GCC warning when WIDE_EMACS_INT.
19220 * indent.c (sane_tab_width): New function.
19221 (current_column, scan_for_column, Findent_to, position_indentation)
19222 (compute_motion): Use it. This is just for clarity.
19223 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19225 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19227 * lisp.h (lint_assume): New macro.
19228 * composite.c (composition_gstring_put_cache):
19229 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19231 * editfns.c, insdel.c:
19232 Omit unnecessary forward decls, to simplify future changes.
19234 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19236 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19238 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19239 Use much-faster test for byte-length change.
19240 Don't assume string byte-length fits in 'int'.
19241 Check that character arg fits in 'int'.
19242 (mapcar1): Declare byte as byte, for clarity.
19244 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19246 * fns.c (concat): Catch string overflow earlier.
19247 Do not rely on integer wraparound.
19249 * dispextern.h (struct it.overlay_strings_charpos)
19250 (struct it.selective): Now EMACS_INT, not int.
19251 * xdisp.c (forward_to_next_line_start)
19252 (back_to_previous_visible_line_start)
19253 (reseat_at_next_visible_line_start, next_element_from_buffer):
19254 Don't arbitrarily truncate the value of 'selective' to int.
19256 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19258 * composite.c: Don't truncate sizes to 'int'.
19259 (composition_gstring_p, composition_reseat_it)
19260 (composition_adjust_point): Use EMACS_INT, not int.
19261 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19262 not EMACS_UINT, for indexes.
19264 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19266 * buffer.c: Include <verify.h>.
19267 (struct sortvec.priority, struct sortstr.priority):
19268 Now EMACS_INT, not int.
19269 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19270 (struct sortstr.size, record_overlay_string)
19271 (struct sortstrlist.size, struct sortlist.used):
19272 Don't truncate size to int.
19273 (record_overlay_string): Check for size-calculation overflow.
19274 (init_buffer_once): Check at compile-time, not run-time.
19276 2011-06-22 Jim Meyering <meyering@redhat.com>
19278 Don't leak an XBM-image-sized buffer
19279 * image.c (xbm_load): Free the image buffer after using it.
19281 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19284 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19285 that Sun C diagnosed.
19286 * fns.c (secure_hash): Fix pointer signedness issue.
19287 * intervals.c (static_offset_intervals): New function.
19288 (offset_intervals): Use it.
19290 2011-06-21 Leo Liu <sdl.web@gmail.com>
19293 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19296 * fns.c (secure_hash): Rename from crypto_hash_function and change
19297 the first arg to accept symbols.
19298 (Fsecure_hash): New primitive.
19299 (syms_of_fns): New symbols.
19301 2011-06-20 Deniz Dogan <deniz@dogan.se>
19303 * process.c (Fset_process_buffer): Clarify return value in
19306 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19308 * dispnew.c (add_window_display_history): Use BVAR.
19310 * xdisp.c (debug_method_add): Use BVAR.
19311 (check_window_end, dump_glyph_matrix, dump_glyph)
19312 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19314 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19317 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19318 check till after the cache is created in init_frame_faces.
19320 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19322 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19324 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19326 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19327 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19328 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19330 Improve buffer-overflow checking (Bug#8873).
19331 * fileio.c (Finsert_file_contents):
19332 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19333 Remove the old (too-loose) buffer overflow checks.
19334 They weren't needed, since make_gap checks for buffer overflow.
19335 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19336 The old code merely checked for Emacs fixnum overflow, and relied
19337 on undefined (wraparound) behavior. The new code avoids undefined
19338 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19340 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19341 Tune. Don't use wider integers than needed. Don't use alloca.
19342 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19344 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19346 * insdel.c, lisp.h (buffer_overflow): New function.
19347 (insert_from_buffer_1, replace_range, replace_range_2):
19348 * insdel.c (make_gap_larger):
19349 * editfns.c (Finsert_char):
19350 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19352 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19354 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19356 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19358 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19359 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19361 * fileio.c: Don't assume EMACS_INT fits in off_t.
19362 (emacs_lseek): New static function.
19363 (Finsert_file_contents, Fwrite_region): Use it.
19364 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19366 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19368 * fns.c: Don't overflow int when computing a list length.
19369 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19370 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19371 truncation on 64-bit hosts. Check for QUIT every
19372 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19373 faster and is responsive enough.
19374 (Flength): Report an error instead of overflowing an integer.
19375 (Fsafe_length): Return a float if the value is not representable
19376 as a fixnum. This shouldn't happen except in contrived situations.
19377 (Fnthcdr, Fsort): Don't assume list length fits in int.
19378 (Fcopy_sequence): Don't assume vector length fits in int.
19380 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19381 (header_size, word_size): New constants.
19382 (allocate_vectorlike): Don't check size overflow here.
19383 (allocate_vector): Check it here instead, since this is the only
19384 caller of allocate_vectorlike that could cause overflow.
19385 Check that the new vector's length is representable as a fixnum.
19387 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19388 The previous code was bogus. For example, next_almost_prime (32)
19389 returned 39, which is undesirable as it is a multiple of 3; and
19390 next_almost_prime (24) returned 25, which is a multiple of 5 so
19391 why was the code bothering to check for multiples of 7?
19393 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19395 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19397 Variadic C functions now count arguments with ptrdiff_t.
19398 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19399 Back then I didn't know that the Emacs coding style prefers signed int.
19400 Also, in the meantime I found a few more instances where arguments
19401 were being counted with int, which may truncate counts on 64-bit
19402 machines, or EMACS_INT, which may be unnecessarily wide.
19403 * lisp.h (struct Lisp_Subr.function.aMANY)
19404 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19405 Arg counts are now ptrdiff_t, not size_t.
19406 All variadic functions and their callers changed accordingly.
19407 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19408 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19409 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19410 * callint.c (Fcall_interactively): Check arg count for overflow,
19411 to avoid potential buffer overrun. Use signed char, not 'int',
19412 for 'varies' array, so that we needn't bother to check its size
19413 calculation for overflow.
19414 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19415 * eval.c (apply_lambda):
19416 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19417 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19418 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19420 * callint.c (Fcall_interactively): Don't use index var as event count.
19422 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19423 * mem-limits.h (SIZE): Remove; no longer used.
19425 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19427 Remove unnecessary casts.
19428 * xterm.c (x_term_init):
19429 * xfns.c (x_set_border_pixel):
19430 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19431 These aren't needed now that we assume ANSI C.
19433 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19434 It's more likely to cause problems (due to unsigned overflow)
19437 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19439 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19441 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19443 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19445 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19447 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19449 GLYPH_CODE_FACE returns EMACS_INT, not int.
19450 * dispextern.h (merge_faces):
19451 * xfaces.c (merge_faces):
19452 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19453 Don't assume EMACS_INT fits in int.
19455 * character.h (CHAR_VALID_P): Remove unused parameter.
19456 * fontset.c, lisp.h, xdisp.c: All uses changed.
19458 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19460 * fns.c (concat): Minor tuning based on overflow analysis.
19461 This doesn't fix any bugs. Use int to hold character, instead
19462 of constantly refetching from Emacs object. Use XFASTINT, not
19463 XINT, for value known to be a character. Don't bother comparing
19464 a single byte to 0400, as it's always less.
19466 * floatfns.c (Fexpt):
19467 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19469 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19472 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19474 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19475 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19476 incorrectly succeed when S was a string, because 4294967386 was
19477 truncated before it was used.
19479 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19480 Otherwise, an out-of-range integer could cause undefined behavior
19483 * composite.c: Use int, not EMACS_INT, for characters.
19484 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19485 EMACS_INT, for values that are known to be in character range.
19486 This doesn't fix any bugs but is the usual style inside Emacs and
19487 may generate better code on 32-bit machines.
19489 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19490 This is for reasons similar to the recent CHAR_STRING fix.
19491 * charset.c (Fencode_char): Check that character arg is actually
19492 a character. Pass an int to ENCODE_CHAR.
19493 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19494 wider than 'int', as a compile-time check to prevent future regressions
19497 * character.c (char_string): Remove unnecessary casts.
19499 Make sure a 64-bit char is never passed to CHAR_STRING.
19500 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19501 by silently ignoring the top 32 bits, allowing some values
19502 that were far too large to be valid characters.
19503 * character.h: Include <verify.h>.
19504 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19505 arguments are no wider than unsigned, as a compile-time check
19506 to prevent future regressions in this area.
19508 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19509 (Fsubst_char_in_region):
19511 * xdisp.c (decode_mode_spec_coding):
19512 Adjust to CHAR_STRING's new requirement.
19513 * editfns.c (Finsert_char, Fsubst_char_in_region):
19514 * fns.c (concat): Check that character args are actually
19515 characters. Without this test, these functions did the wrong
19516 thing with wildly out-of-range values on 64-bit hosts.
19518 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19519 These casts should not be needed on 32-bit hosts, either.
19520 * keyboard.c (read_char):
19521 * lread.c (Fload): Remove casts to unsigned.
19523 * lisp.h (UNSIGNED_CMP): New macro.
19524 This fixes comparison bugs on 64-bit hosts.
19525 (ASCII_CHAR_P): Use it.
19526 * casefiddle.c (casify_object):
19527 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19528 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19529 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19530 * dispextern.h (FACE_FROM_ID):
19531 * keyboard.c (read_char): Use UNSIGNED_CMP.
19533 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19534 not to EMACS_INT, to avoid GCC warning.
19536 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19538 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19539 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19540 isn't needed on 32-bit machines.
19542 * buffer.c (Fgenerate_new_buffer_name):
19543 Use EMACS_INT for count, not int.
19544 (advance_to_char_boundary): Return EMACS_INT, not int.
19546 * data.c (Qcompiled_function): Now static.
19548 * window.c (window_body_lines): Now static.
19550 * image.c (gif_load): Rename local to avoid shadowing.
19552 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.

20187 were just reseat()'ed to a new position.
20189 * xdisp.c (set_cursor_from_row): Set start and stop points
20190 according to the row's direction when priming the loop that looks

20193 (display_prop_intangible_p): Reimplement to call
20194 handle_display_spec instead of single_display_spec_intangible_p.

20205 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20206 value of a `display' property is a "replacing spec".
20207 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20208 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20209 the display property, but just return a value indicating whether
20210 the display property will replace the characters it covers.
20211 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20212 frame_window_p members of struct bidi_it.

20238 * gnutls.c: Use Emacs's memory allocators.
20239 Without this change, the gnutls library would invoke malloc etc.
20240 directly, which causes problems on non-SYNC_INPUT hosts, and which
20241 runs afoul of improving memory_full behavior. (Bug#8761)
20242 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20243 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20244 xfree instead of the default malloc, realloc, free.
20245 (Fgnutls_boot): No need to check for memory allocation failure,
20246 since xmalloc does that for us.

20275 need to be updated by these changes.
20276 * fns.c (make_hash_table, maybe_resize_hash_table):
20277 Check for integer overflow with large hash tables.
20278 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20279 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20280 (SXHASH_REDUCE): New macro.
20281 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20282 Use it instead of discarding useful hash info with large hash values.
20283 (sxhash_float): New function.
20284 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20285 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20286 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20287 Rewrite to use FIXNUM_BITS, as this simplifies things.
20288 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20289 Adjust signatures to match updated version of code.
20290 (consing_since_gc): Now EMACS_INT, since a single hash table can
20291 use more than INT_MAX bytes.

20421 Check for serial numbers out of range. Decode any serial number
20422 that was so large that it became a float. (Bug#8722)
20424 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20425 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20426 Use XFASTINT rather than XUINT when numbers are nonnegative.
20427 (xd_append_arg, Fdbus_method_return_internal):
20428 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20429 arguments, check that Lisp number is nonnegative, rather than
20430 silently wrapping negative numbers around. (Bug#8722)
20431 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20434 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20436 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20438 ccl: Add integer overflow checks.
20439 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20440 (IN_INT_RANGE): New macros.
20441 (ccl_driver): Use them to check for integer overflow when
20442 decoding a CCL program. Many of the new checks are whether XINT (x)
20443 fits in int; it doesn't always, on 64-bit hosts. The new version
20444 doesn't catch all possible integer overflows, but it's an
20445 improvement. (Bug#8719)
20447 * alloc.c (make_event_array): Use XINT, not XUINT.
20448 There's no need for unsigned here.
20450 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20451 This follows up to the 2011-05-06 change that substituted uintptr_t
20452 for EMACS_INT. This case wasn't caught back then.
20454 Rework Fformat to avoid integer overflow issues.
20455 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20456 now (part of C89). Include <verify.h>.
20457 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20458 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20459 (Fformat): Avoid the prepass trying to compute sizes; it was only
20460 approximate and thus did not catch overflow reliably. Instead, walk
20461 through the format just once, formatting and computing sizes as we go,
20462 checking for integer overflow at every step, and allocating a larger
20463 buffer as needed. Keep track separately whether the format is
20464 multibyte. Keep only the most-recently calculated precision, rather
20465 than them all. Record whether each argument has been converted to
20466 string. Use EMACS_INT, not int, for byte and char and arg counts.
20467 Support field widths and precisions larger than INT_MAX. Avoid
20468 sprintf's undefined behavior with conversion specifications such as %#d
20469 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20470 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20471 formatting out-of-range floating point numbers with int
20472 formats. (Bug#8668)
20474 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20476 * data.c: Avoid integer truncation in expressions involving floats.
20477 * data.c: Include <intprops.h>.
20478 (arith_driver): When there's an integer overflow in an expression
20479 involving floating point, convert the integers to floating point
20480 so that the resulting value does not suffer from catastrophic
20481 integer truncation. For example, on a 64-bit host (* 4
20482 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20483 Do not rely on undefined behavior after integer overflow.
20485 merge count_size_as_multibyte, parse_str_to_multibyte
20486 * character.c, character.h (count_size_as_multibyte):
20487 Rename from parse_str_to_multibyte; all uses changed.
20488 Check for integer overflow.
20489 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20490 since it's now a duplicate of the other. This is more of
20491 a character than a buffer op, so better that it's in character.c.
20492 * fns.c, print.c: Adjust to above changes.
20494 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20496 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20498 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20500 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20501 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20502 (x_clipboard_manager_save): Now static.
20503 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20505 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20506 (crypto_hash_function): Now static.
20507 Fix pointer signedness problems. Avoid unnecessary initializations.
20509 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20511 * termhooks.h (Vselection_alist): Make it terminal-local.
20513 * terminal.c (create_terminal): Initialize it.
20515 * xselect.c: Support for clipboard managers.
20516 (Vselection_alist): Move to termhooks.h as terminal-local var.
20517 (LOCAL_SELECTION): New macro.
20518 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20519 (symbol_to_x_atom): Remove gratuitous arg.
20520 (x_handle_selection_request, lisp_data_to_selection_data)
20521 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20522 (x_own_selection, x_get_local_selection, x_convert_selection):
20523 New arg, specifying work frame. Use terminal-local Vselection_alist.
20524 (some_frame_on_display): Delete unused function.
20525 (Fx_own_selection_internal, Fx_get_selection_internal)
20526 (Fx_disown_selection_internal, Fx_selection_owner_p)
20527 (Fx_selection_exists_p): New optional frame arg.
20528 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20529 (x_handle_selection_clear): Don't treat other terminals with the
20530 same keyboard specially. Use the terminal-local Vselection_alist.
20531 (x_clear_frame_selections): Use Frun_hook_with_args.
20533 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20535 * xterm.h: Add support for those atoms.
20537 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20539 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20540 (converted_selections, conversion_fail_tag): New global variables.
20541 (x_selection_request_lisp_error): Free the above.
20542 (x_get_local_selection): Remove unnecessary code.
20543 (x_reply_selection_request): Args changed; handle arbitrary array
20544 of converted selections stored in converted_selections.
20545 Separate the XChangeProperty and SelectionNotify steps.
20546 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20547 (x_convert_selection): New function.
20548 (x_handle_selection_event): Simplify.
20549 (x_get_foreign_selection): Don't ignore incoming requests while
20550 waiting for an answer; this will fail when we implement
20551 SAVE_TARGETS, and seems unnecessary anyway.
20552 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20553 (Vx_sent_selection_functions): Doc fix.
20555 2011-05-26 Leo Liu <sdl.web@gmail.com>
20557 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20559 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20561 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20563 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20564 for fringe update if it has periodic bitmap.
20565 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20566 and fringe_bitmap_periodic_p.
20568 * fringe.c (get_fringe_bitmap_data): New function.
20569 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20570 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20571 row. Mark glyph row for fringe update if periodicity changed.
20573 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20574 for fringe update unless it has periodic bitmap.
20576 2011-05-25 Kenichi Handa <handa@m17n.org>
20578 * xdisp.c (get_next_display_element): Set correct it->face_id for
20579 a static composition.
20581 2011-05-24 Leo Liu <sdl.web@gmail.com>
20584 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20586 * fns.c (crypto_hash_function, Fsha1): New function.
20587 (Fmd5): Use crypto_hash_function.
20588 (syms_of_fns): Add Ssha1.
20590 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20592 * gnutls.c: Remove unused macros.
20593 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20594 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20595 Remove macros that are defined and never used.
20596 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20598 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20600 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20601 (Fx_get_selection_internal): Minor cleanup.
20602 (Fx_own_selection_internal): Rename arguments for consistency with
20605 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20607 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20609 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20611 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20613 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20615 * dispnew.c (scrolling_window): Don't exclude the case that the
20616 last enabled row in the desired matrix touches the bottom boundary.
20618 2011-05-21 Glenn Morris <rgm@gnu.org>
20620 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20621 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20622 and add some more files.
20624 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20626 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20627 report_file_error introduced by the change from 2011-05-07.
20629 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20631 * systime.h (Time): Define only if emacs is defined.
20632 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20633 where the include path doesn't have X11/X.h by default. See
20634 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20636 2011-05-20 Kenichi Handa <handa@m17n.org>
20638 * composite.c (find_automatic_composition): Fix previous change.
20640 2011-05-20 Glenn Morris <rgm@gnu.org>
20642 * lisp.mk: New file, split from Makefile.in.
20643 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20644 (shortlisp): Remove.
20645 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20647 2011-05-19 Glenn Morris <rgm@gnu.org>
20649 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20650 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20651 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20652 (lisp): Set the order to that of loadup.el.
20653 (shortlisp): Make it a copy of $lisp.
20654 (SOME_MACHINE_LISP): Remove.
20655 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20656 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20658 2011-05-18 Kenichi Handa <handa@m17n.org>
20660 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20661 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20662 (find_automatic_composition): Mostly rewrite for efficiency.
20664 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20666 * makefile.w32-in: Update dependencies.
20668 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20670 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20671 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20673 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20675 Fix some integer overflow issues, such as string length overflow.
20677 * insdel.c (count_size_as_multibyte): Check for string overflow.
20679 * character.c (lisp_string_width): Check for string overflow.
20680 Use EMACS_INT, not int, for string indexes and lengths; in
20681 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20682 the resulting string length overflows an EMACS_INT; instead,
20683 report a string overflow if no precision given. When checking for
20684 precision exhaustion, use a check that cannot possibly have
20685 integer overflow. (Bug#8675)
20686 * character.h (lisp_string_width): Adjust to new signature.
20688 * alloc.c (string_overflow): New function.
20689 (Fmake_string): Use it. This doesn't change behavior, but saves
20690 a few bytes and will simplify future changes.
20691 * character.c (string_escape_byte8): Likewise.
20692 * lisp.h (string_overflow): New decl.
20694 Fixups, following up to the user-interface timestamp change.
20695 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20696 for UI timestamps, instead of unsigned long.
20697 * msdos.c (mouse_get_pos): Likewise.
20698 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20699 * w32gui.h (Time): Define by including "systime.h" rather than by
20700 declaring it ourselves. (Bug#8664)
20702 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20703 * image.c (clear_image_cache): Likewise.
20705 * term.c (term_mouse_position): Don't assume time_t wraparound.
20707 Be more systematic about user-interface timestamps.
20708 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20709 and sometimes 'EMACS_UINT', to represent these timestamps.
20710 This change causes it to use 'Time' uniformly, as that's what X uses.
20711 This makes the code easier to follow, and makes it easier to catch
20712 integer overflow bugs such as Bug#8664.
20713 * frame.c (Fmouse_position, Fmouse_pixel_position):
20714 Use Time, not unsigned long, for user-interface timestamps.
20715 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20716 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20717 * keyboard.h (last_event_timestamp): Likewise.
20718 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20719 * menu.h (xmenu_show): Likewise.
20720 * term.c (term_mouse_position): Likewise.
20721 * termhooks.h (struct input_event.timestamp): Likewise.
20722 (struct terminal.mouse_position_hook): Likewise.
20723 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20724 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20725 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20726 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20727 what it was before.
20728 * menu.h, termhooks.h: Include "systime.h", for Time.
20730 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20731 Don't assume that the difference between two unsigned long values
20732 can fit into an integer. At this point, we know button_down_time
20733 <= event->timestamp, so the difference must be nonnegative, so
20734 there's no need to cast the result if double-click-time is
20735 nonnegative, as it should be; check that it's nonnegative, just in
20736 case. This bug is triggered when events are more than 2**31 ms
20737 apart (about 25 days). (Bug#8664)
20739 * xselect.c (last_event_timestamp): Remove duplicate decl.
20740 (x_own_selection): Remove needless cast to unsigned long.
20742 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20743 that always fit in int. Use a sentinel instead of a counter, to
20744 avoid a temp and to allay GCC's concerns about possible int overflow.
20745 * frame.h (struct frame): Use int for menu_bar_items_used
20746 instead of EMACS_INT, since it always fits in int.
20748 * menu.c (grow_menu_items): Check for int overflow.
20750 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20752 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20753 Before, the code was not consistent. These values cannot exceed
20754 2**31 - 1 so there's no need to make them unsigned.
20755 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20756 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20757 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20759 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20761 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20762 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20763 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20764 presumably because the widths might not match.
20766 * window.c (size_window): Avoid needless test at loop start.
20768 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20770 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20772 2011-05-12 Drew Adams <drew.adams@oracle.com>
20774 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20776 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20778 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20779 `width' to `bar_area_x' and `bar_area_width', respectively.
20780 (x_scroll_run): Take account of fringe background extension.
20782 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20783 Rename local vars `left' and `width' to `bar_area_x' and
20784 `bar_area_width', respectively.
20785 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20786 background extension.
20788 2011-05-10 Jim Meyering <meyering@redhat.com>
20790 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20792 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20794 * image.c (Finit_image_library): Return t for built-in image types,
20795 like pbm and xbm. (Bug#8640)
20797 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20799 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20801 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20803 * w32console.c (Fset_screen_color): Doc fix.
20804 (Fget_screen_color): New function.
20805 (syms_of_ntterm): Defsubr it.
20807 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20808 unlink the temporary file if Fcall_process didn't create it in the
20810 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20811 child process will be redirected to a file specified with `:file'.
20812 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20813 cue to call_process_cleanup not to close that handle.
20815 2011-05-07 Ben Key <bkey76@gmail.com>
20817 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20818 one of two shell specific rules, either bootstrap-temacs-CMD or
20819 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20820 to the previous implementation of the bootstrap-temacs rule.
20821 The bootstrap-temacs-CMD rule is similar to the previous
20822 implementation of the bootstrap-temacs rule except that it
20823 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20826 These changes, along with some changes to nt/configure.bat,
20827 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20828 earlier fix to add support for --cflags and --ldflags options
20829 that include quotes so that it works whether make uses cmd or
20832 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20834 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20835 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20837 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20838 a string. Handle both cases.
20839 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20840 (Fdbus_register_method): Use Qinvalid_function.
20842 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20844 * makefile.w32-in: Update dependencies.
20845 (LISP_H): Add inttypes.h and stdin.h.
20846 (PROCESS_H): Add unistd.h.
20848 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20850 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20851 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20853 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20855 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20857 * term.c (vfatal): Remove stray call to va_end.
20858 It's not needed and the C Standard doesn't allow it here anyway.
20860 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20861 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20863 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20866 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20868 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20870 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20872 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20874 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20876 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20877 * charset.c (Fdefine_charset_internal): Don't initialize
20878 charset.code_space[15]. The value was garbage, on hosts with
20879 32-bit int (Bug#8600).
20881 * lread.c (read_integer): Be more consistent with string-to-number.
20882 Use string_to_number to do the actual conversion; this avoids
20883 rounding errors and fixes some other screwups. Without this fix,
20884 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20885 (digit_to_number): Move earlier, for benefit of read_integer.
20886 Return -1 if the digit is out of range for the base, -2 if it is
20887 not a digit in any supported base. (Bug#8602)
20889 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20891 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20892 to match comment at start of function. This also removes a
20893 GCC warning about overflow in a 32+64-bit port.
20895 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20897 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20898 Reported by Stefan Monnier in
20899 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20900 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20901 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20903 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20904 (EMACS_UINTPTR): Likewise, with uintptr_t.
20906 * lisp.h: Prefer 64-bit EMACS_INT if available.
20907 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20908 on 32-bit hosts that have 64-bit int, so that they can access
20910 However, temporarily disable this change unless the temporary
20911 symbol WIDE_EMACS_INT is defined.
20913 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20915 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20916 This removes an assumption that EMACS_INT and long are the same
20917 width as pointers. The assumption is true for Emacs porting targets
20918 now, but we want to make other targets possible.
20919 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20920 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20921 In the rest of the code, change types of integers that hold casted
20922 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20923 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20924 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20925 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20926 No need to cast type when ORing.
20927 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20928 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20929 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20930 assume EMACS_INT is the same width as char *.
20931 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20932 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20933 Remove no-longer-needed casts.
20934 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20935 (xg_tool_bar_help_callback, xg_make_tool_item):
20936 Use EMACS_INTPTR to hold an integer
20937 that will be cast to void *; this can avoid a GCC warning
20938 if EMACS_INT is not the same width as void *.
20939 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20940 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20941 (current_message_1, set_message_1):
20942 Use a local to convert to proper width without a cast.
20943 * xmenu.c (dialog_selection_callback): Likewise.
20945 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20946 Also, don't assume VALBITS / RAND_BITS is less than 5,
20947 and don't rely on undefined behavior when shifting a 1 left into
20949 * lisp.h (get_random): Change signature to match.
20951 * lread.c (hash_string): Use size_t, not int, for hash computation.
20952 Normally we prefer signed values; but hashing is special, because
20953 it's better to use unsigned division on hash table sizes so that
20954 the remainder is nonnegative. Also, size_t is the natural width
20955 for hashing into memory. The previous code used 'int', which doesn't
20956 retain enough info to hash well into very large tables.
20957 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20959 * dbusbind.c: Don't possibly lose pointer info when converting.
20960 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20961 Use XPNTR rather than XHASH, so that the high-order bits of
20962 the pointer aren't lost when converting through void *.
20964 * eval.c (Fautoload): Don't double-shift a pointer.
20966 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20968 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20970 * gnutls.c (DEF_GNUTLS_FN):
20971 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20973 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20975 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20978 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20980 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20981 New version that can reserve upto 2GB of heap space.
20983 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20985 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20987 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20989 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20990 `gnutls_certificate_set_x509_key_file'.
20992 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20994 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20995 Update dependencies.
20997 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20999 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21000 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21001 Remove unused parameter `fildes'.
21002 * process.c (read_process_output, send_process): Don't pass it.
21004 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21006 Fix previous change: the library cache is defined in w32.c.
21007 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21008 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21010 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21012 Implement dynamic loading of GnuTLS on Windows.
21014 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21015 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21016 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21019 * gnutls.c (Qgnutls_dll): Define.
21020 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21021 (gnutls_*): Declare function pointers.
21022 (init_gnutls_functions): New function to initialize function pointers.

21024 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21025 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21026 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21027 (emacs_gnutls_write, emacs_gnutls_read)
21028 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21029 (Fgnutls_available_p): New function.
21030 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21031 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21032 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21034 * image.c: Include w32.h.
21035 (Vimage_type_cache): Delete.
21036 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21037 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21038 (w32_delayed_load): Move to w32.c.
21040 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21042 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21043 (w32_delayed_load): Move from image.c. When loading a library, record
21044 its filename in the :loaded-from property of the library id.
21045 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21046 Initialize and staticpro them.
21047 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21049 * process.c: Include lisp.h before w32.h, not after.
21050 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21051 instead of gnutls_record_check_pending.
21053 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21055 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21057 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21058 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21061 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21063 * xterm.c (x_set_frame_alpha): Do not set property on anything
21064 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21066 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21068 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21070 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21072 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21073 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21086 * sysdep.c (wait_for_termination_1): Make static.
21087 (wait_for_termination, interruptible_wait_for_termination):
21088 Move after wait_for_termination_1.
21090 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21092 * sysdep.c (interruptible_wait_for_termination): New function
21093 which is like wait_for_termination, but allows keyboard
21096 * callproc.c (Fcall_process): Add (:file "file") as an option for
21098 (Fcall_process_region): Ditto.
21100 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21102 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21103 rather than `XVECTOR (FOO)->size'.
21105 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21106 inttypes.h, as a gnulib replacement is used if it not available in
21109 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21111 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21112 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21113 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21115 * coding.c (coding_alloc_by_realloc): Error out if destination
21116 will grow beyond MOST_POSITIVE_FIXNUM.
21117 (decode_coding_emacs_mule): Abort if there isn't enough place in
21118 charbuf for the composition carryover bytes. Reserve an extra
21119 space for up to 2 characters produced in a loop.
21120 (decode_coding_iso_2022): Abort if there isn't enough place in
21121 charbuf for the composition carryover bytes.
21123 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21125 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21126 aborting when %lld or %lll format is passed.
21127 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21128 %llo or %llx format is passed. (Bug#8545)
21130 * window.c (window_scroll_line_based): Use a marker instead of
21131 simple variables to record original value of point. (Bug#7952)
21133 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21134 produced by %s or %c overflows available buffer space. (Bug#8545)
21136 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21138 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21139 (SIZE_MAX): Move defn after all includes, as they might #define it.
21141 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21143 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21145 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21147 * keyboard.c (Qdelayed_warnings_hook): Define.
21148 (command_loop_1): Run `delayed-warnings-hook'
21149 if Vdelayed_warnings_list is non-nil.
21150 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21151 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21153 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21155 * doprnt.c (doprnt): Don't return value smaller than the buffer
21156 size if the message was truncated. (Bug#8545).
21158 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21160 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21161 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21163 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21165 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21167 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21169 * makefile.w32-in: Update dependencies.
21171 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21173 Improve `doprnt' and its usage. (Bug#8545)
21174 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21175 `format_end'. Remove support for %l as a conversion specifier.
21176 Don't use xrealloc. Improve diagnostics when the %l size modifier
21177 is used. Update the commentary.
21179 * eval.c (verror): Simplify calculation of size_t.
21181 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21184 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21186 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21189 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21191 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21192 This makes this file independent of the recent pseudovector change.
21194 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21196 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21198 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21199 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21200 Remove unused local.
21201 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21203 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21204 GCC 4.6.0 optimizes based on type-based alias analysis.
21205 For example, if b is of type struct buffer * and v of type struct
21206 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21207 != &v->size, and therefore "v->size = 1; b->size = 2; return
21208 v->size;" must therefore return 1. This assumption is incorrect
21209 for Emacs, since it type-puns struct Lisp_Vector * with many other
21210 types. To fix this problem, this patch adds a new type struct
21211 vectorlike_header that documents the constraints on layout of vectors
21212 and pseudovectors, and helps optimizing compilers not get fooled
21213 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21214 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21215 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21217 (XSETPVECTYPE): Rewrite in terms of new macro.
21218 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21219 This is a bit clearer, and further avoids the possibility of
21220 undesirable aliasing.
21221 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21222 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21223 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21224 since Lisp_Subr is a special case (no "next" field).
21225 (ASIZE): Now uses header.size rather than size.
21226 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21227 to avoid the hassle of writing XVECTOR (foo)->header.size.
21228 (struct vectorlike_header): New type.
21229 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21230 object, to help avoid aliasing.
21231 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21232 (SUBRP): Likewise, since Lisp_Subr is a special case.
21233 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21234 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21235 (struct Lisp_Hash_Table): Combine first two members into a single
21236 struct vectorlike_header member. All uses of "size" and "next" members
21237 changed to be "header.size" and "header.next".
21238 * buffer.h (struct buffer): Likewise.
21239 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21240 * frame.h (struct frame): Likewise.
21241 * process.h (struct Lisp_Process): Likewise.
21242 * termhooks.h (struct terminal): Likewise.
21243 * window.c (struct save_window_data, struct saved_window): Likewise.
21244 * window.h (struct window): Likewise.
21245 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21246 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21247 * buffer.c (init_buffer_once): Likewise.
21248 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21250 * process.c (Fformat_network_address): Use local var for size,
21253 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21255 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21256 * data.c (atof): Remove decl; no longer used or needed.
21257 (digit_to_number): Move to lread.c.
21258 (Fstring_to_number): Use new string_to_number function, to be
21259 consistent with how the Lisp reader treats infinities and NaNs.
21260 Do not assume that floating-point numbers represent EMACS_INT
21261 without losing information; this is not true on most 64-bit hosts.
21262 Avoid double-rounding errors, by insisting on integers when
21263 parsing non-base-10 numbers, as the documentation specifies.
21264 * lisp.h (string_to_number): New decl, replacing ...
21265 (isfloat_string): Remove.
21266 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21267 (read1): Do not accept +. and -. as integers; this
21268 appears to have been a coding error. Similarly, do not accept
21269 strings like +-1e0 as floating point numbers. Do not report
21270 overflow for integer overflows unless the base is not 10 which
21271 means we have no simple and reliable way to continue.
21272 Break out the floating-point parsing into a new
21273 function string_to_number, so that Fstring_to_number parses
21274 floating point numbers consistently with the Lisp reader.
21275 (digit_to_number): Move here from data.c. Make it static inline.
21276 (E_CHAR, EXP_INT): Remove, replacing with ...
21277 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21278 (string_to_number): New function, replacing isfloat_string.
21279 This function checks for valid syntax and produces the resulting
21280 Lisp float number too. Rework it so that string-to-number
21281 no longer mishandles examples like "1.0e+". Use strtoumax,
21282 so that overflow for non-base-10 numbers is reported only when
21283 there's no portable and simple way to convert to floating point.
21285 * textprop.c (set_text_properties_1): Rewrite for clarity,
21286 and to avoid GCC warning about integer overflow.
21288 * intervals.h (struct interval): Use EMACS_INT for members
21289 where EMACS_UINT might cause problems. See
21290 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21291 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21292 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21294 (offset_intervals): Tell GCC not to worry about length overflow
21295 when negating a negative length.
21297 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21298 (overrun_check_free): Likewise.
21300 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21301 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21304 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21305 (gnutls_make_error): Rename local to avoid shadowing.
21306 (gnutls_emacs_global_deinit): ifdef out; not used.
21307 (Fgnutls_boot): Use const for pointer to readonly storage.
21308 Comment out unused local. Fix pointer signedness problems.
21310 * lread.c (openp): Don't stuff size_t into an 'int'.
21311 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21312 about possible signed overflow.
21314 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21315 (GDK_KEY_g): Don't define if already defined.
21316 (xg_prepare_tooltip): Avoid pointer signedness problem.
21317 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21319 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21320 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21322 * xfns.c (Fx_window_property): Simplify a bit,
21323 to make a bit faster and to avoid GCC 4.6.0 warning.
21324 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21326 * fns.c (internal_equal): Don't assume size_t fits in int.
21328 * alloc.c (compact_small_strings): Tighten assertion a little.
21330 Replace pEd with more-general pI, and fix some printf arg casts.
21331 * lisp.h (pI): New macro, generalizing old pEd macro to other
21332 conversion specifiers. For example, use "...%"pI"d..." rather
21333 than "...%"pEd"...".
21334 (pEd): Remove. All uses replaced with similar uses of pI.
21335 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21336 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21337 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21338 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21339 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21340 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21341 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21343 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21344 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21345 * print.c (safe_debug_print, print_object): Likewise.
21346 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21348 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21349 avoiding the 0 flag, which is not portable.
21350 * process.c (Fmake_network_process): Use pI to avoid cast.
21351 * region-cache.c (pp_cache): Likewise.
21352 * xdisp.c (decode_mode_spec): Likewise.
21353 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21354 behavior on 64-bit hosts with printf arg.
21355 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21356 (x_stop_queuing_selection_requests): Likewise.
21357 (x_get_window_property): Don't truncate byte count to an 'int'
21360 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21361 here, since it parses constructs like leading '-' and spaces,
21362 which are not wanted; and it overflows with large numbers.
21363 Instead, simply match F[0-9]+, which is what is wanted anyway.
21365 * alloc.c: Remove unportable assumptions about struct layout.
21366 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21367 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21368 (allocate_vectorlike, make_pure_vector): Use the new macros,
21369 plus offsetof, to remove unportable assumptions about struct layout.
21370 These assumptions hold on all porting targets that I know of, but
21371 they are not guaranteed, they're easy to remove, and removing them
21372 makes further changes easier.
21374 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21375 This doesn't fix a bug but makes the code clearer.
21376 (string_overrun_cookie): Now const. Use initializers that
21377 don't formally overflow signed char, to avoid warnings.
21378 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21379 can cause Emacs to crash when string overrun checking is enabled.
21380 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21381 multiple of sizeof (EMACS_INT); it need not be, if
21382 alignof(EMACS_INT) < sizeof (EMACS_INT).
21383 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21385 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21412 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21414 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21415 "cast to pointer from integer of different size".
21417 Improve doprnt and its use in verror. (Bug#8545)
21418 * doprnt.c (doprnt): Document the set of format control sequences
21419 supported by the function. Use SAFE_ALLOCA instead of always
21422 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21423 is one byte too soon. Don't use xrealloc; instead xfree and
21426 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21428 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21431 * gnutls.c: Renamed global_initialized to
21432 gnutls_global_initialized. Added internals for the
21433 :verify-hostname-error, :verify-error, and :verify-flags
21434 parameters of `gnutls-boot' and documented those parameters in the
21435 docstring. Start callback support.
21436 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21437 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21513 Many local variables are now size_t instead of int or unsigned.
21514 Improve overflow protection. Support `l' modifier for integer
21515 conversions. Support %l conversion. Don't assume an EMACS_INT
21516 argument for integer conversions and for %c.
21518 * lisp.h (doprnt): Restore prototype.
21520 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21521 $(SRC)/character.h.

21541 codepoint of an invalid character, to avoid displaying a bogus
21544 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21545 `error', not SYMBOL_NAME itself.

21550 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21551 to `error' in error message about FINAL_CHAR argument. Make sure
21552 FINAL_CHAR is a character, and use %c when it is passed as
21553 argument to `error'.
21555 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21557 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21559 * w32.c: Include <time.h>.

21620 by pacifying GCC about it. Maybe it's time to retire it?
21621 * xfaces.c (USG, __TIMEVAL__): Likewise.
21623 * dispextern.h (struct redisplay_interface): Rename param
21624 to avoid shadowing.
21625 * termhooks.h (struct terminal): Likewise.
21626 * xterm.c (xembed_send_message): Likewise.
21628 * insdel.c (make_gap_smaller): Define only if
21629 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
21631 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
21634 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
21635 so that we aren't warned about unused symbols.

21652 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
21654 * xmenu.c (menu_help_callback): Pointer type fixes.

21672 compatible char. Avoid the old compiler warnings about
21673 out-of-range initializers by using, for example, '\xab' rather
21676 * xgselect.c (xgselect_initialize): Check vs interface
21677 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

21704 2011-04-16 Eli Zaretskii <eliz@gnu.org>
21706 * gnutls.c (Fgnutls_boot): Don't pass Lisp_Object to `error'.

21726 (bcmp_translate, regcomp, regexec, print_double_string)
21727 (group_in_compile_stack, re_search, re_search_2, regex_compile)
21728 (re_compile_pattern, re_exec): Declare arguments and local
21729 variables `size_t' and `ssize_t' and return values `regoff_t', as
21731 (POP_FAILURE_REG_OR_COUNT) <pfreg>: Declare `long'.
21732 (CHECK_INFINITE_LOOP) <failure>: Declare `ssize_t'.

21737 specify buffer/string position and length are now ssize_t and
21738 size_t. Return type is regoff_t.
21740 2011-04-16 Ben Key <bkey76@gmail.com>
21742 * nsfont.m: Fixed bugs in ns_get_family and
21743 ns_descriptor_to_entity that were caused by using free to
21744 deallocate memory blocks that were allocated by xmalloc (via
21745 xstrdup). This caused Emacs to crash when compiled with
21746 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

22164 Remove decls, since these functions are now static.
22165 (Funintern, Fget_internal_run_time): New decls, since these functions
22166 were already external.
22168 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22169 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

22175 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22176 Mark functions with DEFUE instead of DEFUN,
22177 if they are used in other modules.
22178 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22179 decls for now-static functions.
22180 * buffer.h (Fdelete_overlay): Remove decl.
22181 * callproc.c (Fgetenv_internal): Mark as internal.

22216 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22218 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22219 when at ZV. (Bug#8487)
22221 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22223 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22225 * keyboard.c (parse_tool_bar_item): Likewise.
22226 * sound.c (sound_cleanup, alsa_close): Likewise.
22227 * termcap.c (tgetent): Likewise.
22228 * xfns.c (x_default_font_parameter): Likewise.
22229 * xsettings.c (read_and_apply_settings): Likewise.
22231 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22232 (overrun_check_free): Protoize.
22234 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22236 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22237 since callers should never pass a negative size.
22238 Change the signature to match that of plain 'read' and 'write'; see
22239 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22240 * lisp.h: Update prototypes of emacs_write and emacs_read.
22242 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22244 * xdisp.c (redisplay_window): Don't try to determine the character
22245 position of the scroll margin if the window start point w->startp
22246 is outside the buffer's accessible region. (Bug#8468)
22248 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22250 Fix write-region and its subroutines for buffers > 2GB.
22251 * fileio.c (a_write, e_write): Modify declaration of arguments and
22252 local variables to support buffers larger than 2GB.
22253 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22255 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22256 argument, local variables, and return value.
22258 * lisp.h: Update prototypes of emacs_write and emacs_read.
22260 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22262 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22264 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22266 Fix more problems found by GCC 4.6.0's static checks.
22268 * xdisp.c (vmessage): Use a better test for character truncation.
22270 * charset.c (load_charset_map): <, not <=, for optimization,
22271 and to avoid potential problems with integer overflow.
22272 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22273 * casetab.c (set_identity, shuffle): Likewise.
22274 * editfns.c (Fformat): Likewise.
22275 * syntax.c (skip_chars): Likewise.
22277 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22278 This also lets GCC 4.6.0 generate slightly better loop code.
22280 * callint.c (Fcall_interactively): <, not <=, for optimization.
22281 (Fcall_interactively): Count the number of arguments produced,
22282 not the number of arguments given. This is simpler and lets GCC
22283 4.6.0 generate slightly better code.
22285 * ftfont.c: Distingish more carefully between FcChar8 and char.
22286 The previous code passed unsigned char * to a functions like
22287 strlen and xstrcasecmp that expect char *, which does not
22288 conform to the C standard.
22289 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22290 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22291 char * when the C standard requires it.
22293 * keyboard.c (read_char): Remove unused var.
22295 * eval.c: Port to Windows vsnprintf (Bug#8435).
22296 Include <limits.h>.
22297 (SIZE_MAX): Define if the headers do not.
22298 (verror): Do not give up if vsnprintf returns a negative count.
22299 Instead, grow the buffer. This ports to Windows vsnprintf, which
22300 does not conform to C99. Problem reported by Eli Zaretskii.
22301 Also, simplify the allocation scheme, by avoiding the need for
22302 calling realloc, and removing the ALLOCATED variable.
22304 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22306 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22307 But keep the doprint source code for now, as we might revamp it
22308 and use it again (Bug#8435).
22309 * lisp.h (doprnt): Remove.
22310 * Makefile.in (base_obj): Remove doprnt.o.
22311 * deps.mk (doprnt.o): Remove.
22313 error: Print 32- and 64-bit integers portably (Bug#8435).
22314 Without this change, on typical 64-bit hosts error ("...%d...", N)
22315 was used to print both 32- and 64-bit integers N, which relied on
22316 undefined behavior.
22317 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22318 * lisp.h (error, verror): Mark as printf-like functions.
22319 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22320 Report overflow in size calculations when allocating printf buffer.
22321 Do not truncate output string at its first null byte.
22322 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22323 Truncate the output at a character boundary, since vsnprintf does not
22325 * charset.c (check_iso_charset_parameter): Convert internal
22326 character to string before calling 'error', since %c now has the
22328 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22329 overflow when computing char to be passed to 'error'. Do not
22330 pass Lisp_Object to 'error'; pass the integer instead.
22331 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22332 formatted with plain %d.
22334 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22336 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22338 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22340 * xterm.c (x_catch_errors): Remove duplicate declaration.
22342 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22344 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22346 2011-04-10 Jim Meyering <meyering@redhat.com>
22348 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22349 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22350 return ssize_t not "int", and use size_t as the buffer length.
22351 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22352 * gnutls.h: Update declarations.
22353 * process.c (read_process_output): Use ssize_t, to match.
22354 (send_process): Likewise.
22356 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22358 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22360 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22362 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22363 Use unsigned char, to match FcChar8 type definition.
22365 * xterm.c (handle_one_xevent):
22366 * xmenu.c (create_and_show_popup_menu):
22367 * xselect.c (x_decline_selection_request)
22368 (x_reply_selection_request): Avoid type-punned deref of X events.
22370 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22372 Fix some uses of `int' instead of EMACS_INT.
22373 * search.c (string_match_1, fast_string_match)
22374 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22375 (scan_buffer, find_next_newline_no_quit)
22376 (find_before_next_newline, search_command, Freplace_match)
22377 (Fmatch_data): Make some `int' variables be EMACS_INT.
22379 * xdisp.c (display_count_lines): 3rd argument and return value now
22380 EMACS_INT. All callers changed.
22381 (pint2hrstr): Last argument is now EMACS_INT.
22383 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22384 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22385 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22386 (decode_coding_utf_16, decode_coding_emacs_mule)

22388 (decode_coding_ccl, decode_coding_charset)
22389 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22390 (decode_coding_iso_2022, decode_coding_emacs_mule)
22391 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22392 <char_offset, last_offset>: Declare EMACS_INT.

22395 (encode_designation_at_bol, encode_coding_iso_2022)
22396 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22397 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22399 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22400 (encode_invocation_designation): Last argument P_NCHARS is now
22402 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22403 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22405 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22408 * ccl.c (Fccl_execute_on_string): Declare some variables
22411 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22413 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22415 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22417 * process.c (Fformat_network_address): Doc fix.
22419 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22421 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22423 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22425 * keyboard.c (read_char): Call Lisp function help-form-show,
22426 instead of using internal_with_output_to_temp_buffer.
22427 (Qhelp_form_show): New var.
22428 (syms_of_keyboard): Use DEFSYM macro.
22430 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22432 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22434 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22436 * process.c (Flist_processes): Remove to Lisp.
22437 (list_processes_1): Delete.
22439 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22441 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22443 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22445 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22447 Fix more problems found by GCC 4.6.0's static checks.

22451 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22453 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22455 * xdisp.c (vmessage): Mark as a printf-like function.
22457 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22459 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22461 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22462 printf-like functions.
22463 (tiff_load): Add casts to remove these marks before passing them
22464 to system-supplied API.
22466 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22468 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22469 This avoids several warnings with gcc -Wstrict-overflow.
22470 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22471 directly, rather than having caller test rule sign. This avoids
22472 some unnecessary tests.
22473 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22474 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22475 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22477 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22478 (xfont_open): Avoid unnecessary tests.
22480 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22482 * composite.h, composite.c (composition_gstring_put_cache):
22483 Use EMACS_INT, not int, for length.

22489 by using the new macro.
22491 * textprop.c (set_text_properties_1): Change while to do-while,
22492 since the condition is always true at first.
22494 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22495 (interval_deletion_adjustment): Return unsigned value.
22498 * process.c (list_processes_1, create_pty, read_process_output):

22508 (update_syntax_table): Use unsigned instead of int.
22510 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22511 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22512 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22514 * print.c (print_error_message): Avoid int overflow.
22516 * font.c (font_list_entities): Redo for clarity,
22517 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22519 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22520 (font_score): Avoid potential overflow in diff calculation.
22522 * fns.c (substring_both): Remove var that is set but not used.
22523 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22525 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22527 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22528 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22529 can always succeed if overflow has undefined behavior.
22531 * search.c (boyer_moore, wordify): Remove vars set but not used.
22532 (wordify): Omit three unnecessary tests.
22534 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22535 All callers changed. This avoids the need for an unused var.
22537 * casefiddle.c (casify_region): Remove var that is set but not used.
22539 * dired.c (file_name_completion): Remove var that is set but not used.
22541 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22543 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22544 (Finsert_file_contents): Remove unnecessary code checking fd.
22546 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22547 Check for integer overflow on size calculations.
22549 * buffer.c (Fprevious_overlay_change): Remove var that is set
22552 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22553 Remove vars that are set but not used.
22554 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22555 (timer_check_2): Mark vars as initialized.
22557 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22559 * image.c (lookup_image): Remove var that is set but not used.
22560 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22562 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22563 that are set but not used.
22565 * xfns.c (make_invisible_cursor): Don't return garbage
22566 if XCreateBitmapFromData fails (Bug#8410).
22568 * xselect.c (x_get_local_selection, x_handle_property_notify):
22569 Remove vars that are set but not used.
22571 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22572 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22574 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22575 Remove var that is set but not used.
22576 (scroll_bar_windows_size): Now size_t, not int.
22577 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22578 Check for overflow.
22580 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22581 (map_tty_color) [!defined MSDOS]: Likewise.
22583 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22585 * coding.c: Remove vars that are set but not used.
22586 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22587 All callers changed.
22588 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22589 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22590 (decode_coding_charset): Remove vars that are set but not used.
22592 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22593 that is set but not used.
22595 * print.c (print_object): Remove var that is set but not used.
22597 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22598 The gnulib version avoids calling malloc in the usual case,
22599 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22600 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22601 * filelock.c (current_lock_owner): Likewise.
22602 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22603 * sysdep.c: Include allocator.h, careadlinkat.h.
22604 (emacs_no_realloc_allocator): New static constant.
22605 (emacs_readlink): New function.
22606 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

22628 (get_per_char_metric): Remove parameter `f', unused since
22629 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22631 2011-04-02 Jim Meyering <meyering@redhat.com>
22633 do not dereference NULL upon failed strdup
22634 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22635 (ns_get_family): Likewise.
22637 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22639 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22641 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22643 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22646 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22648 Add lexical binding.
22650 * window.c (Ftemp_output_buffer_show): New fun.
22651 (Fsave_window_excursion):
22652 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

22657 Bind Qinternal_interpreter_environment.
22658 (Feval_buffer): Bind Qlexical_binding.
22659 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22661 (syms_of_lread): Declare `lexical-binding'.
22663 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22665 * keyboard.c (eval_dyn): New fun.
22666 (menu_item_eval_property): Use it.
22668 * image.c (parse_image_spec): Use Ffunctionp.
22670 * fns.c (concat, mapcar1): Accept byte-code-functions.
22672 * eval.c (Fsetq): Handle lexical vars.
22673 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22674 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22675 (FletX, Flet): Obey lexical binding.
22676 (Fcommandp): Handle closures.
22677 (Feval): New `lexical' arg.
22678 (eval_sub): New function extracted from Feval. Use it almost
22679 everywhere where Feval was used. Look up vars in lexical env.
22681 (Ffunctionp): Move from subr.el.
22682 (Ffuncall): Handle closures.
22683 (apply_lambda): Remove `eval_flags'.
22684 (funcall_lambda): Handle closures and new byte-code-functions.
22685 (Fspecial_variable_p): New function.
22686 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22687 but without exporting it to Lisp.
22689 * doc.c (Fdocumentation, store_function_docstring):
22690 * data.c (Finteractive_form): Handle closures.
22692 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22695 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22697 (exec_byte_code): New function extracted from Fbyte_code to handle new
22698 calling convention for byte-code-functions. Add new byte-codes.
22700 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22702 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22704 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22706 * xdisp.c (redisplay_internal): Fix prototype.
22708 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22710 * xdisp.c (SCROLL_LIMIT): New macro.
22711 (try_scrolling): Use it when setting scroll_limit.
22712 Limit scrolling to 100 screen lines.
22713 (redisplay_window): Even when falling back on "recentering",
22714 position point in the window according to scroll-conservatively,
22715 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22717 (try_scrolling): When point is above the window, allow searching
22718 as far as scroll_max, or one screenful, to compute vertical
22719 distance from PT to the scroll margin position. This prevents
22720 try_scrolling from unnecessarily failing when
22721 scroll-conservatively is set to a value slightly larger than the
22722 window height. Clean up the case of PT below the margin at bottom
22723 of window: scroll_max can no longer be INT_MAX. When aggressive
22724 scrolling is in use, don't let point enter the opposite scroll
22725 margin as result of the scroll.
22726 (syms_of_xdisp) <scroll-conservatively>: Document the
22727 threshold of 100 lines for never-recentering scrolling.
22729 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22731 * dispextern.h (move_it_by_lines):
22732 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

22734 (message_log_check_duplicate): Remove parameters `prev_bol' and
22735 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22736 (redisplay_internal): Remove parameter `preserve_echo_area',
22737 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22739 * indent.c (Fvertical_motion):
22740 * window.c (window_scroll_pixel_based, Frecenter):
22741 Don't pass `need_y_p' to `move_it_by_lines'.
22743 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22745 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22746 steal a few bits to be more compact.
22747 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22748 Remove unneeded casts.
22750 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22752 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22754 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22755 binding" message (bug#7967).
22757 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22759 Fix more problems found by GCC 4.6.0's static checks.
22761 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22762 Remove unused local var.
22764 * editfns.c (Fmessage_box): Remove unused local var.
22766 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22767 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22768 Omit unused local vars.
22769 * window.c (shrink_windows): Omit unused local var.
22770 * menu.c (digest_single_submenu): Omit unused local var.
22771 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22772 Omit unused local var.
22774 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22775 Don't assume string length fits in int.
22776 (keyremap_step, read_key_sequence): Use size_t for sizes.
22777 (read_key_sequence): Don't check last_real_key_start redundantly.
22779 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22780 instead of alloca (Bug#8344).
22782 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22783 (Fbacktrace_frame): Don't assume nframes fits in int.
22785 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

22790 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22792 * cm.c (calccost): Turn while-do into do-while, for clarity.
22794 * keyboard.c (syms_of_keyboard): Use the same style as later
22795 in this function when indexing through an array. This also
22796 works around GCC bug 48267.
22798 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22800 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22802 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22803 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22805 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22806 This avoids undefined behavior on integer overflow, and is a bit
22807 more convenient anyway since it is compared to a size_t variable.
22809 Variadic C functions now count arguments with size_t, not int.
22810 This avoids an unnecessary limitation on 64-bit machines, which
22811 caused (substring ...) to crash on large vectors (Bug#8344).

22821 * fns.c (concat): Likewise.
22822 * frame.c (x_set_frame_parameters): Likewise.
22823 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22824 0 if not found, not -1. All callers changed.
22826 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22827 (stack_copy_size): Now size_t, not int.
22828 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22830 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22832 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

22849 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22850 don't set the hook to nil, but remove the offending function instead.
22851 (Qcommand_hook_internal): Remove, unused.
22852 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22853 Vcommand_hook_internal.
22855 * eval.c (enum run_hooks_condition): Remove.
22856 (funcall_nil, funcall_not): New functions.
22857 (run_hook_with_args): Call each function through a `funcall' argument.

23037 unconditionally since it does the check itself.
23039 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23041 Fix more problems found by GCC 4.5.2's static checks.
23043 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23044 the first time through the loop, since we know p0 < p1 then.
23045 This also avoids a gcc -Wstrict-overflow warning.
23047 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23048 leading to a memory leak, possible in functions like
23049 load_charset_map_from_file that can allocate an unbounded number
23050 of objects (Bug#8318).
23052 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23053 that could (at least in theory) be that large.
23055 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23056 This is less likely to overflow, and avoids undefined behavior if
23057 overflow does occur. All callers changed. Use strtoul to scan
23058 for the unsigned long integer.
23059 (pint2hrstr): Simplify and tune code slightly.
23060 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23062 * scroll.c (do_scrolling): Work around GCC bug 48228.
23063 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

23066 This also avoids a warning with gcc -Wstrict-overflow.
23067 (validate_x_resource_name): Simplify count usage.
23068 This also avoids a warning with gcc -Wstrict-overflow.
23070 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23073 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23075 * process.c (Fmake_network_process): Use socklen_t, not int,
23076 where POSIX says socklen_t is required in portable programs.
23077 This fixes a porting bug on hosts like 64-bit HP-UX, where
23078 socklen_t is wider than int (Bug#8277).
23079 (Fmake_network_process, server_accept_connection):
23080 (wait_reading_process_output, read_process_output):
23083 * process.c: Rename or move locals to avoid shadowing.

23093 Make tparam.h and terminfo.c consistent.
23094 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23095 Include tparam.h instead, since it declares them.
23096 * cm.h (PC): Remove extern decl; tparam.h now does this.
23097 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23098 * terminfo.c: Include tparam.h, to check interfaces.
23099 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23100 (tparam): Adjust signature to match interface in tparam.h;
23101 this removes some undefined behavior. Check that outstring and len
23102 are zero, which they always are with Emacs.
23103 * tparam.h (PC, BC, UP): New extern decls.
23105 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23106 (xftfont_open): Rename locals to avoid shadowing.

23123 (find_automatic_composition, composition_adjust_point): Likewise.
23124 (composition_update_it): Mark var as initialized.
23125 (find_automatic_composition): Mark vars as initialized,
23126 with a FIXME (Bug#8290).

23132 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23133 to avoid shadowing.
23135 * textprop.c (property_change_between_p): Remove; unused.
23137 * intervals.c (interval_start_pos): Now static.
23139 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23144 * sound.c (wav_play, au_play, Fplay_sound_internal):
23145 Fix pointer signedness.
23146 (alsa_choose_format): Remove unused local var.
23147 (wav_play): Initialize a variable to 0, to prevent undefined
23148 behavior (Bug#8278).
23150 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23152 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23154 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23155 clobbering (Bug#8298).
23156 * sysdep.c (sys_subshell): Likewise.
23157 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23159 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23160 This should get cleaned up, so that child_setup has the
23161 same signature on all platforms.
23163 * callproc.c (call_process_cleanup): Now static.
23164 (relocate_fd): Rename locals to avoid shadowing.
23166 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23168 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23169 not to be necessary, and produces flickering.
23171 2011-03-20 Glenn Morris <rgm@gnu.org>
23173 * config.in: Remove file.
23175 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23177 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23178 are now in src/globals.h.
23179 (syms_of_minibuf): Remove spurious & from previous change.

23189 * xfaces.c (Fx_load_color_file):
23190 Read color file from absolute filename (bug#8250).
23192 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23194 * makefile.w32-in: Update dependencies.
23196 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23198 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23205 (sigchld_handler): Now static.
23207 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23208 That way, the code declares only the vars that it needs.

23219 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23220 Define only if needed.
23222 * unexelf.c (unexec): Name an expression,
23223 to avoid gcc -Wbad-function-cast warning.
23224 Use a different way to cause a compilation error if anyone uses
23225 n rather than nn, a way that does not involve shadowing.
23226 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23228 * deps.mk (unexalpha.o): Remove; unused.
23230 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23231 * unexec.h: New file.
23232 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23233 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23234 Depend on unexec.h.
23235 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23236 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23237 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23238 Change as necessary to match prototype in unexec.h.

23285 * callint.c (quotify_arg, quotify_args): Now static.
23286 (Fcall_interactively): Rename locals to avoid shadowing.
23287 Use const pointer when appropriate.

23293 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23294 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23295 some of which prompt warnings from gcc -Wbad-function-cast.
23296 (Fformat_time_string, Fencode_time, Finsert_char):
23297 (Ftranslate_region_internal, Fformat):
23298 Rename or remove local vars to avoid shadowing.

23301 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23304 * lisp.h (eassert): Check that the argument compiles, even if
23305 ENABLE_CHECKING is not defined.
23307 * data.c (Findirect_variable): Name an expression, to avoid
23308 gcc -Wbad-function-cast warning.

23320 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23321 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23323 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23324 (GC_STRING_CHARS): Remove; not used.
23325 (Fmemory_limit): Cast sbrk's returned value to char *.
23327 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23328 avoids undefined behavior in theory.
23330 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23332 Use functions, not macros, for up- and down-casing (Bug#8254).
23333 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23334 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23335 to use the following functions instead of these macros.
23336 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23337 EMACS_INT, since callers assume the returned value fits in int.
23338 (upcase1): Likewise, for UPCASE_TABLE.
23339 (uppercasep, lowercasep, upcase): New static inline functions.
23340 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23349 which gcc can warn about.
23350 (regex_compile, re_match_2_internal): Mark locals as initialized.
23351 (RETALLOC_IF): Define only if needed.
23352 (WORDCHAR_P): Likewise. This one is never needed, but is used
23353 only in a comment talking about a compiler bug, so put inside
23354 the #if 0 of that comment.
23355 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23356 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23359 * search.c (boyer_moore): Rename locals to avoid shadowing.
23360 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

23382 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23383 New macros, so that the caller can use some names other than
23384 gcpro1, gcpro2, etc.
23385 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23387 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23388 argument, for consistency with GCPRO2_VAR, etc: it is now the
23389 prefix of the variable, not the variable itself. All uses
23391 * dired.c (directory_files_internal, file_name_completion):
23392 Rename locals to avoid shadowing.
23394 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23395 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23396 dired.c's scmp function, had undefined behavior.
23397 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23398 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23399 * buffer.h: ... to here, because these macros use current_buffer,
23400 and the new implementation with inline functions needs to have
23401 current_buffer in scope now, rather than later when the macros
23403 (downcase, upcase1): New static inline functions.
23404 (DOWNCASE, UPCASE1): Reimplement using these functions.
23405 This avoids undefined behavior in expressions like
23406 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23407 from race conditions in accessing the global variables
23408 case_temp1 and case_temp2.
23409 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23410 * lisp.h (case_temp1, case_temp2): Remove their decls.
23411 * character.h (ASCII_CHAR_P): Move from here ...
23412 * lisp.h: ... to here, so that the inline functions mentioned
23413 above can use them.
23415 * dired.c (directory_files_internal_unwind): Now static.
23417 * fileio.c (file_name_as_directory, directory_file_name):
23418 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23420 (file_name_as_directory): Use const pointers when appropriate.
23421 (Fexpand_file_name): Likewise. In particular, newdir might
23422 point at constant storage, so make it a const pointer.
23423 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23424 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23426 (Fset_file_times, Finsert_file_contents, auto_save_error):
23427 Rename locals to avoid shadowing.
23429 * minibuf.c (choose_minibuf_frame_1): Now static.

23431 to avoid shadowing.
23433 * marker.c (bytepos_to_charpos): Remove; unused.
23435 * lisp.h (verify_bytepos, count_markers): New decls,
23436 so that gcc does not warn that these functions aren't declared.
23438 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23439 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23440 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23441 (copy_text): Remove unused local var.
23443 * filelock.c (within_one_second): Now static.
23444 (lock_file_1): Rename local to avoid shadowing.
23446 * buffer.c (fix_overlays_before): Mark locals as initialized.
23447 (fix_start_end_in_overlays): Likewise. This function should be
23448 simplified by using pointers-to-pointers, but that's a different
23450 (switch_to_buffer_1): Now static.
23451 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23452 (report_overlay_modification): Rename locals to avoid shadowing.
23454 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23455 Fix pointer signedness issue.
23456 (sys_subshell): Mark local as volatile if checking for lint,
23457 to suppress a gcc -Wclobbered warning that does not seem to be right.
23458 (MAXPATHLEN): Define only if needed.
23460 * process.c (serial_open, serial_configure): Move decls from here ...
23461 * systty.h: ... to here, so that they can be checked.
23463 * fns.c (get_random, seed_random): Move extern decls from here ...
23464 * lisp.h: ... to here, so that they can be checked.
23466 * sysdep.c (reset_io): Now static.
23467 (wait_for_termination_signal): Remove; unused.
23469 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
23470 (copy_keymap_item, append_key, push_text_char_description):
23472 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23473 (DENSE_TABLE_SIZE): Remove; unused.
23474 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23475 (describe_map_tree):
23476 Rename locals to avoid shadowing.
23478 * keyboard.c: Declare functions static if they are not used elsewhere.

23484 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
23485 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
23486 (read_key_sequence, read_char): Mark locals as initialized.
