102 * alloc.c (listn): Fix the order the arguments are consed onto the
103 list.
105 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
106 enumeration constants, as PURE and HEAP are too general, and clash
107 with other headers and sources, such as gmalloc.c and the
108 MS-Windows system headers. All users changed.
110 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

125 Improve GDB symbol export (Bug#12036).
126 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
127 arms of an 'if', not using conditional expressions; otherwise GDB
128 complains about the types in the unevaluated arm when the argument
129 is an integer literal.
130 (xgetint): Simplify expression.
131 * alloc.c (gdb_make_enums_visible): New constant. This ports to
132 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
133 Zaretskii in <http://bugs.gnu.org/12036#13>.
134 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
135 needed now that we have gdb_make_enums_visible.
136 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

180 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
181 emacs.c, as this is a more-suitable home. Had this been done earlier
182 the fix for 12036 would have avoided some of the problems noted in
183 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
184 would have been more obvious.
185 * emacs.c: Do not include <verify.h>; no longer needed.
186 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
187 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
188 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

193 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
194 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
195 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
196 not be usable in #if. This simplifies things.
198 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
200 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
202 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

205 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
206 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
207 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
208 Adjust to changes in lisp.h and emacs.c, by using
209 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
210 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
211 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
212 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
213 instead of gdb_valbits.
214 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
215 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
216 instead of gdb_array_mark_flag.
217 (xboolvector): Get size from $->size, not $->header.size.
218 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
219 (xreload, hook-run, hookpost-run): Remove.
220 * emacs.c: Include <verify.h>.
221 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
222 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
223 Remove.
224 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
225 (gdb_USE_LSB_TAG): New enum constants.
226 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
227 Also define these as enum constants, so they're visible to GDB.
228 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
229 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
230 as constants, so they're visible to GDB.
231 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
232 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
233 Now enum constants, not macros, so they're visible to GDB.
234 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
235 more convenient now. All uses changed.
236 (VALMASK) [USE_LSB_TAG]: Also define in this case.
237 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

247 add argument, tune behavior, and adjust all callers.
249 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
251 Use typedef for EMACS_INT, EMACS_UINT.
252 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
253 than macros. This simplifies debugging in the usual case, since
254 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
255 and it allows expressions involving EMACS_INT casts.
256 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
258 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
260 * nsterm.m (ns_read_socket): Return early if there is a modal

270 Adjust buffer text indirection counters at the end of Fkill_buffer.
271 * buffer.c (Fkill_buffer): Adjust indirection counters when the
272 buffer is definitely dead. This should really fix an issue reported
273 by Christoph Scholtes again. (Bug#12007).
274 (init_buffer_once): Initialize indirection counters of
275 buffer_defaults and buffer_local_symbols (for sanity and safety).
277 2012-07-24 Eli Zaretskii <eliz@gnu.org>
279 * xdisp.c (init_iterator): Don't compute dimensions of truncation
280 and continuation glyphs on tooltip frames, leave them at zero.
281 Avoids continued lines in tooltips. (Bug#11832)
283 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
285 Simplify copy_overlay.
286 * buffer.c (copy_overlay): Simplify. Use build_marker.

292 or invalid. (Bug#12025)
294 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
295 it signals an error when a tooltip frame is being created.
297 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
299 Cleanup miscellaneous objects allocation and initialization.
300 * alloc.c (allocate_misc): Change to static. Add argument to

306 (build_overlay): Add prototype.
308 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
310 Swap buffer text indirection counters in Fbuffer_swap_text.
311 * buffer.c (Fbuffer_swap_text): Swap indirections too.
312 This avoids crash reported by Christoph Scholtes at
313 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
315 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
317 * nsmenu.m (Popdown_data): New struct.
318 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
319 free Popdown_data.
320 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
321 (initWithContentRect): Make imgView and contentView non-static
322 and autorelease them. Also autorelease img and matrix (Bug#12005).
323 (dealloc): Remove (Bug#12005).

340 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
342 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
343 as it's limited by the amount of memory, not by INT_MAX.
345 2012-07-21 Eli Zaretskii <eliz@gnu.org>
347 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
348 in special-event-map. See the discussion at
349 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
350 for the reasons.
352 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

407 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
408 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
409 Adjust users accordingly.
410 * font.h (font_open_by_name): Adjust prototype.
412 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

428 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
429 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
430 'for_each_per_buffer_object_at'.
431 All uses changed. It's better to use upper-case for macros that
432 cannot be implemented as functions, to give the reader a clue
433 that they're special.
435 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
437 * alloc.c (Fgarbage_collect): Tweak docstring.

1018 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
1019 function attribute, so we only use it if it exists in the
1020 compiler.
1022 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
1024 Avoid call to strlen in fast_c_string_match_ignore_case.

1071 * s/aix4-2.h (unix): Remove; no longer needed.
1073 EMACS_TIME simplification (Bug#11875).
1074 This replaces macros (which typically do not work in GDB)
1075 with functions, typedefs and enums, making the code easier to debug.
1076 The functional style also makes code easier to read and maintain.
1077 * systime.h: Include <sys/time.h> on all hosts, not just if
1078 WINDOWSNT, since 'struct timeval' is needed in general.

1091 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1092 not functions. All uses rewritten to use the following, respectively:
1093 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1094 (add_emacs_time, sub_emacs_time): New functions.
1095 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1097 * xterm.c (XTflash): Get the current time closer to when it's used.
1098 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1109 * regex.c (regerror):
1110 Prefer memcpy to strncpy and strncat when either will do.
1111 * fileio.c (Fsubstitute_in_file_name):
1112 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1113 (menu_separator_name_p):
1114 * nsmenu.m (ns_update_menubar):
1115 Prefer memcmp to strncmp when either will do.
1116 * nsterm.m: Include <ftoastr.h>.
1117 (ns_get_color):
1118 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1119 Prefer snprintf to strncpy.
1120 * nsterm.m (ns_term_init):
1121 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1122 * nsterm.m (ns_term_init):
1123 Avoid the need for strncpy, by using build_string or
1124 make_unibyte_string directly. Use dtoastr, not snprintf.
1125 * process.c (Fmake_network_process): Diagnose service names that
1126 are too long, rather than silently truncating them or creating
1127 non-null-terminated names.

1129 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1130 Prefer sprintf to strncat.
1131 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1132 Prefer vsnprintf to vsprintf + strncpy.
1134 2012-07-10 Glenn Morris <rgm@gnu.org>

1143 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1144 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1145 where argument type is known to be a Lisp_Cons.

1160 provides a better opportunity to optimize away calls to strlen when
1161 the function is called with compile-time constant argument.
1162 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1163 argument, adjust users accordingly. Use build_pure_c_string where
1164 appropriate.

1166 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1167 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1169 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1171 Avoid calls to strlen in miscellaneous functions.
1172 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1173 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1174 * lread.c (openp): Likewise.
1176 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1178 Avoid calls to strlen in path processing functions.
1179 * fileio.c (file_name_as_directory): Add comment. Change to add
1180 srclen argument and return the length of result. Adjust users
1181 accordingly.

1196 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1197 We include usg5-4-common.h, which defines them both.
1199 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1200 O_RDONLY already includes it).
1202 Stop ns builds setting the EMACSLOADPATH environment variable.
1203 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1204 Now it does not set EMACSLOADPATH, just returns the load-path string.
1205 * nsterm.h: Update accordingly.
1206 * lread.c [HAVE_NS]: Include nsterm.h.
1207 (init_lread) [HAVE_NS]: Use ns_load_path.

1210 2012-07-09 Glenn Morris <rgm@gnu.org>
1212 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1213 since the included bsd-common.h does so.
1215 Stop ns builds setting the EMACSPATH environment variable.
1216 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1217 (ns_init_paths): Do not set EMACSPATH.
1218 * nsterm.h (ns_exec_path): Add it.
1219 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:

1224 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1226 * process.c (wait_reading_process_output): 'waitchannels' was unset
1227 when read_kbd || !NILP (wait_for_cell); fix this.
1229 Add GCC-style 'const' attribute to functions that can use it.
1230 * character.h (char_resolve_modifier_mask):
1231 * keyboard.h (make_ctrl_char):
1232 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1243 Minor improvements to make_formatted_string.
1244 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1245 where int is good enough, as vsprintf returns an int.
1246 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1248 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1250 Use make_formatted_string to avoid double length calculation.

1277 Move marker debugging code under MARKER_DEBUG.
1278 * marker.c (MARKER_DEBUG): Move marker debugging code under
1279 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1280 for bootstrap with --enable-checking (~3x slowdown reported
1281 by Juanma Barranquero <lekktu@gmail.com>).
1282 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1284 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1286 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1287 See <http://bugs.gnu.org/11825#29>.
1289 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1291 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1292 has no font, use the frame's font. (Bug#11813)
1293 (display_line): Add commentary about displaying truncation glyphs
1294 on GUI frames.
1295 (produce_special_glyphs): Move here from term.c.
1297 * term.c (produce_special_glyphs): Move to xdisp.c.
1299 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1300 section.
1302 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1304 * xdisp.c (display_line): Avoid warning about implicit declaration
1305 of FRAME_FONT.
1307 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1309 * lisp.h: Remove empty conditional.
1311 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1313 * lread.c (load_path_check): Now static.
1315 Fix some minor --with-ns problems found by static checking.
1316 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1317 (x_set_font) [!HAVE_X_WINDOWS]:
1318 * image.c (xpm_load_image) [HAVE_NS]:
1319 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1320 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1321 Remove unused local.

1330 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1332 2012-07-07 Glenn Morris <rgm@gnu.org>
1334 * lread.c (load_path_check): New function, split from init_lread.
1335 (init_lread): Reorganize. Motivation:
1336 If EMACSLOADPATH is set, check/warn about that rather than the
1337 defaults, which we are not going to use. Hence we can remove
1338 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1339 Don't warn if site-lisp directories are missing.
1340 If not installed, start from a blank load-path, since
1341 PATH_LOADSEARCH refers to the eventual installation directories.
1343 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1345 Support truncation and continuation glyphs on GUI frames, when
1346 fringes are disabled. (Bug#11832)
1347 * xdisp.c (init_iterator): Get dimensions of truncation and
1348 continuation glyphs even if on GUI frames. Adjust
1349 it->last_visible_x on GUI frames when the left or right fringes,
1350 or both, are absent.
1351 (start_display, move_it_in_display_line_to): Handle the case of a
1352 GUI frame without a fringe to display continuation or truncation
1353 glyphs.
1354 (insert_left_trunc_glyphs): Support GUI frames: make sure
1355 truncation glyphs overwrite enough glyphs from the current line to
1356 have sufficient space in pixels.
1357 (display_line): Support truncation and continuation glyphs on GUI
1358 frames. If some spare pixels are left on the line after inserting
1359 the truncation glyphs, fill that space with a stretch glyph of a
1360 suitably computed width.
1362 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1363 produce_glyphs, to support GUI sessions.
1365 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1367 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1369 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1371 Do not require float-time's arg to fit in time_t (Bug#11825).
1372 This works better on hosts where time_t is unsigned, and where
1373 float-time is applied to the (negative) difference between two times.
1374 * editfns.c (decode_time_components): Last arg is now double *,
1375 not int *, and means to store all the result as a double, without
1376 worrying about whether the seconds part fits in time_t.
1377 All callers changed.
1378 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1379 All callers changed.
1380 (Ffloat_time): Do not fail merely because the specified time falls
1381 outside of time_t range.
1383 2012-07-07 Glenn Morris <rgm@gnu.org>
1385 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1405 * xfont.c (compare_font_names): Redo to omit the need for casts.
1407 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1409 * xfns.c (Fx_change_window_property): Doc fix.
1410 * w32fns.c (Fx_change_window_property): Doc fix.
1412 * w32fns.c (Fx_window_property): Accept the same arguments as the
1413 X Windows version. Doc fix.
1414 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1416 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1417 Eli Zaretskii <eliz@gnu.org>
1419 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1420 Windows-specific code from nt/config.nt moved here.
1421 Obsolete settings removed.
1423 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1425 * process.c: Avoid unnecessary calls to gettime.
1426 (wait_reading_process_output): Don't get the time of day
1427 when gobbling data immediately and not waiting, as there's no need
1428 for it in that case. This removes a FIXME.
1430 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1432 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1433 is defined (Bug#11768).
1435 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1437 Fix marker debugging code.
1438 * marker.c (byte_char_debug_check): Do not perform the check
1439 if buffer is not multibyte.
1440 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1441 Call byte_char_debug_check with correct arguments.
1443 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1445 Compile marker debugging code only if ENABLE_CHECKING is defined.
1446 * marker.c (byte_char_debug_check, count_markers):
1447 Use only if ENABLE_CHECKING is defined.
1448 (byte_debug_flag): Remove.
1449 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1450 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1452 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1454 Avoid code repetition in marker-related functions.
1455 * marker.c (attach_marker): New function.
1456 (Fset_marker, set_marker_restricted, set_marker_both)
1457 (set_marker_restricted_both): Use it.
1458 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1459 Consistently rename charno to charpos.
1460 (marker_position): Add eassert.
1461 (marker_byte_position): Convert to eassert.
1463 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1477 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1478 (save_restriction_save): Use build_marker.
1479 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1480 * window.c (save_window_save): Likewise.
1482 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1484 Do not use Fdelete_overlay in delete_all_overlays
1485 to avoid redundant calls to unchain_overlay.
1486 * buffer.c (drop_overlay): New function.
1487 (delete_all_overlays, Fdelete_overlay): Use it.
1488 * minibuf.c (get_minibuffer): Fix comment.
1490 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1492 Port to OpenBSD 5.1 amd64.
1493 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1494 This is needed for OpenBSD, and should be harmless on all BSD systems.
1495 Also, include <sys/sysctl.h>, as it should be available on all
1496 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1497 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1498 use p_pid member, not kp_proc.pid.
1500 2012-07-06 Glenn Morris <rgm@gnu.org>
1502 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1504 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1506 More xmalloc and related cleanup.
1507 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

1515 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1516 * xterm.c:
1517 Omit needless casts involving void * pointers and allocation.
1518 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1519 as the former is more robust if P's type is changed.
1520 Prefer xzalloc to xmalloc + memset 0.
1521 Simplify malloc-or-realloc to realloc.
1522 Don't worry about xmalloc returning a null pointer.
1523 Prefer xstrdup to xmalloc + strcpy.
1524 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1525 growing it.
1526 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1527 alloca of a constant.
1529 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1531 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1532 hscroll is larger than the line width. Fixes long and futile
1533 looping inside extend_face_to_end_of_line (on a TTY) producing
1534 glyphs that are not needed and thrown away.
1536 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1538 * marker.c (set_marker_restricted_both): Simplify by using
1539 clip_to_bounds.
1541 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1543 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1545 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

1548 not defined (Bug#11768).
1549 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1550 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1551 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1552 followed by gtk_box_set_homogeneous (Bug#11768).
1553 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1554 (update_theme_scrollbar_width, xg_create_scroll_bar):
1555 Use gtk_scrollbar_new (Bug#11768).
1556 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1557 (is_box_type): New function (Bug#11768).
1558 (xg_tool_item_stale_p): Call is_box_type.
1559 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1560 with default display (Bug#11768).
1562 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1564 * xdisp.c (window_hscroll_limited): New function.
1565 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1566 coordinates when window's hscroll is set to insanely large
1567 values. (Bug#11857)
1569 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1571 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1572 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1574 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

1630 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1632 * fileio.c (time_error_value): Check the right error number.
1633 Problem reported by Troels Nielsen in
1634 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1636 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1638 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1639 This should be fixed in a better way; see Eli Zaretskii in
1640 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1641 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1643 * fileio.c (time_error_value): Rename from special_mtime.
1644 The old name's problems were noted by Eli Zaretskii in
1645 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1647 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1648 This variable's comment says Emacs needs at least one GDB-visible
1649 symbol of type enum pvec_type, to work around GDB problems.
1650 The symbol's value doesn't matter.
1652 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1653 that causes compilation to fail on pre-C99 compilers.
1655 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1657 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1658 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1660 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1662 * buffer.c (init_buffer_once): Fix initialization of
1663 headers for buffer_defaults and buffer_local_symbols.
1664 Reported by Juanma Barranquero <lekktu@gmail.com>.
1666 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1668 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1669 * lisp.h (enum pvec_type): Use fewer bits.
1670 (PSEUDOVECTOR_SIZE_BITS): New constant.
1671 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1672 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1673 change in pvec_type.

1680 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1681 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1682 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1683 abusing vector->header.next.nbytes.
1684 (live_vector_p): Use PVEC_TYPE.
1685 (mark_object): Adapt code to extract pvectype. Use switch.
1687 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1689 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1690 Tighten new eassert a bit.
1692 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1694 Fix compilation with --enable-gcc-warnings and -O1
1695 optimization level.
1696 * doprnt.c (doprnt): Change type of tem to int, initialize
1697 to avoid compiler warning. Add eassert.
1698 * search.c (simple_search): Initialize match_byte to avoid
1699 compiler warning. Add eassert.
1701 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1703 Avoid weird behavior with large horizontal scrolls.
1704 Without this change, for example, large hscroll values would
1705 mess up Emacs's display on Fedora 15 x86, presumably due to
1706 overflows in int calculations in the display code.
1707 Also, if buffers had long lines, Emacs would freeze.
1708 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1709 (set_window_hscroll): New function, containing the old guts of
1710 Fset_window_hscroll. Return the clipped value.
1711 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1712 This avoids the need to check against PTRDIFF_MAX.
1714 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1716 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1718 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1720 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1722 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1723 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1724 since GCC 4.4.6 issues a bogus warning for them.
1726 Fix bugs in file timestamp newness comparisons.
1727 * fileio.c (Ffile_newer_than_file_p):
1728 * lread.c (Fload): Use full timestamp resolution of files,
1729 not just the 1-second resolution, so that files that are only
1730 slightly newer still count as newer.
1731 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1732 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1734 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1736 * fileio.c: Improve handling of file time marker. (Bug#11852)

1741 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1743 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1744 marker for non-existing file. (Bug#11852)
1746 2012-07-03 Glenn Morris <rgm@gnu.org>
1748 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1749 and did not make it into globals.h).
1751 2012-07-03 Tom Tromey <tromey@redhat.com>
1753 * window.c (Fset_window_margins, Fset_window_fringes)

1793 buffer for invisible buffers. (Bug#1229)
1795 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1797 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1798 values which aren't power of 2.
1799 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1800 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1801 accordingly.
1803 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1805 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1807 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1809 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1811 * alloc.c (allocate_vector_block): Remove redundant
1812 calls to mallopt if DOUG_LEA_MALLOC is defined.
1813 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1814 avoid calls to mallopt if zero_vector is returned.
1816 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1818 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1819 is enabled, avoid dereferencing NULL current_sblock if
1820 running undumped.
1822 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1824 Cleanup basic buffer management.
1825 * buffer.h (struct buffer): Change layout to use generic vector
1826 marking code. Fix some comments. Change type of 'clip_changed'
1827 to bitfield. Remove unused #ifndef old.
1828 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1829 (GET_OVERLAYS_AT): Fix indentation.
1830 (for_each_per_buffer_object_at): New macro.
1831 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1832 (Fbuffer_local_variables): Use it.
1833 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1834 * alloc.c (allocate_buffer): Adjust to match new layout of
1835 struct buffer. Fix comment.
1836 (mark_overlay): New function.
1837 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1838 Lisp area of struct buffer.
1839 (mark_object): Use it. Adjust marking of misc objects
1840 and related comments.
1842 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1844 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1845 wrapper that is not needed because the wrapped code is a no-op (zero
1846 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1847 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1849 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1851 * alloc.c (mark_buffer): Simplify. Remove prototype.
1852 (mark_object): Add comment. Reorganize marking of vector-like
1853 objects. Use CHECK_LIVE for all vector-like objects except buffers
1854 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1855 redundant calls to mark_vectorlike for bool vectors.
1857 2012-06-30 Glenn Morris <rgm@gnu.org>
1859 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1861 * epaths.in (PATH_SITELOADSEARCH): New.
1862 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1863 This is rather than relying on --enable-locallisppath elements
1864 having "site-lisp" in their names. (Bug#10208#25, 11658)
1866 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1868 * w32proc.c (sys_select): Accept and ignore one more argument.
1870 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1872 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1873 (pselect) [!MS_DOS]: Redirect to sys_select.
1875 * sysdep.c: Don't include dos.h and dosfns.h.
1877 * process.c (sys_select):
1878 * msdos.c (sys_select): Accept one more argument and ignore it.
1880 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1881 adapt data types and code to that.
1883 * dosfns.c:
1884 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1885 which clashes with the gnulib function of the same name.
1887 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1889 * font.c (font_style_to_value, font_style_symbolic)
1890 (font_prop_validate_style): Add type checks for values in
1891 font_style_table.
1893 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1894 argument.
1895 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1896 uses.
1898 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1900 * xdisp.c (try_window_id): Undo last change.
1902 * w32.c (getwd): Adjust commentary about startup_dir.
1903 (init_environment): Always call sys_access, even in non-MSVC
1904 builds. Don't chdir to the directory of the Emacs executable.
1905 This undoes code from 1997 which was justified by the need to
1906 "avoid conflicts when removing and renaming directories". But its
1907 downside was that every relative file name was being interpreted
1908 relative to the directory of the Emacs executable, which can never
1909 be TRT. In particular, it broke sys_access when called with
1910 relative file names.
1911 (sys_access): Map GetLastError to errno.
1913 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1915 * window.h (struct window): Change type of 'fringes_outside_margins'
1916 to bitfield. Fix comment. Adjust users accordingly.
1917 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
1918 Adjust comment.
1919 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1920 to ptrdiff_t.
1922 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1924 * gnutls.c (emacs_gnutls_handshake):
1925 Add QUIT to make the loop interruptible.
1927 2012-06-29 Glenn Morris <rgm@gnu.org>
1929 * charset.c (init_charset): Make lack of etc/charsets fatal.
1931 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1933 * editfns.c (region_limit): Fix type mismatch.
1935 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1937 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1938 undefined. Convert from xassert to eassert.
1939 * nsmenu.m: Convert from xassert to eassert.
1940 * nsterm.m: Likewise.
1942 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

1946 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1948 Avoid integer overflow on scroll-left and scroll-right.
1949 * window.c (HSCROLL_MAX): New macro.
1950 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1951 overflow when requested scroll falls outside ptrdiff_t range.
1953 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1955 * window.h (struct window): Change type of 'hscroll',
1956 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1957 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1958 Adjust users accordingly.
1959 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1960 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1961 from EMACS_INT to ptrdiff_t.
1962 (make_window): Omit redundant initialization.
1964 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1966 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1968 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1970 * window.h (struct window): Change type of 'use_time' and

1980 enabled with --enable-checking=[all,glyphs] configure option.
1981 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1982 adjust comments accordingly.

2027 purify-hashtable.
2029 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2031 * alloc.c (allocate_string_data): Remove dead code.
2032 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2033 avoid GCC warning about unused macro.
2035 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2037 * alloc.c (allocate_string): Omit intervals initialization.
2038 * alloc.c (make_uninit_multibyte_string): Initialize intervals

2097 a better opportunity to optimize away calls to strlen when the
2098 function is called with compile-time constant argument.

2103 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2105 Use sprintf return value instead of invoking strlen on result.
2106 In the old days this wasn't portable, since some sprintf
2107 implementations returned char *. But they died out years ago and
2108 Emacs already assumes sprintf returns int.
2109 Similarly for float_to_string.
2110 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2111 * ccl.c (ccl_driver):
2112 * character.c (string_escape_byte8):

2115 * print.c (print_object):
2116 * xdisp.c (message_dolog):
2117 * xfns.c (syms_of_xfns):
2118 Use sprintf or float_to_string result to avoid need to call strlen.
2119 * data.c (Fnumber_to_string):
2120 Use make_unibyte_string, since the string must be ASCII.
2121 * lisp.h, print.c (float_to_string): Now returns int length.
2122 * term.c (produce_glyphless_glyph):
2123 Use sprintf result rather than recomputing it.
2125 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2126 * Makefile.in (ALL_CFLAGS):
2127 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2149 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2151 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2152 sprintf already null-terminates its output.
2154 * xfns.c (x_window): Remove redundant cast.
2156 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2158 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2159 `const char *' to `char *' to avoid compiler warning.
2161 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2163 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2164 instead of truncating it to 63 (admittedly a generous limit).
2166 * process.c: Fix spelling and caps in comments.
2168 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2170 * emacs.c (setpgrp): Remove definition, unused.

2180 (SYSTIME_H): Add nt/inc/sys/time.h.
2182 * systime.h [WINDOWSNT]: Include sys/time.h.
2184 * s/ms-w32.h (struct timespec): Definition moved from
2185 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
2187 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2217 Remove unnecessary forward decls.
2219 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2223 * dispnew.c (Fsleep_for, sit_for):
2224 * keyboard.c (kbd_buffer_get_event):
2225 * process.c (Faccept_process_output):
2226 Use it to avoid bogus compiler warnings with obsolescent GCC versions.

2228 when time_t is unsigned and as wide as intmax_t.
2229 See <http://bugs.gnu.org/9000#51>.
2231 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2233 * dispnew.c (sit_for, Fsleep_for):
2234 * keyboard.c (kbd_buffer_get_event):

2260 language ID in the event parameters.
2262 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2263 event.code, not the obscure "character set ID".

2294 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2296 Support higher-resolution time stamps (Bug#9000).
2297 The time stamps are only nanosecond-resolution at the C level,
2298 since that's the best that any real-world system supports now.
2299 But they are picosecond-resolution at the Lisp level, as that's
2300 easy, and leaves room for future OS improvements.
2302 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2303 (LIBES): Use it.
2305 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2306 Don't get current time unless it's needed.
2308 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2309 now provides it if it's absent.
2310 (start_atimer): Port to higher-res time stamps.
2311 Check for time stamp overflow. Don't get current time more
2312 often than is needed.
2314 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2315 Include systime.h, not time.h.
2316 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2318 * dired.c: Include stat-time.h.
2319 (Ffile-attributes): File times now have higher resolution.
2321 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2322 (struct image): Timestamp now has higher resolution.
2324 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2325 has at least microseconds now. All uses removed.
2326 (update_frame, update_single_window, update_window, update_frame_1)
2327 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2329 * editfns.c (time_overflow): Now extern.
2330 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2331 (float-time, Fformat_time_string, Fcurrent_time_string)
2332 (Fcurrent_time_zone): Accept and generate higher-resolution
2333 time stamps.
2334 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2335 (decode_time_components, lisp_seconds_argument): New functions.
2336 (make_time): Now static.
2337 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2338 Report an error if the time is invalid, rather than having the caller
2339 do that.
2341 * fileio.c: Include <stat-time.h>
2342 (Fcopy_file): Copy higher-resolution time stamps.
2343 Prefer to set the time stamp via a file descriptor if that works.

2345 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2346 (Fvisited_file_modtime, Fset_visited_file_modtime):
2347 Support higher-resolution time stamps.
2349 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2351 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2353 * image.c (prepare_image_for_display, clear_image_cache)
2354 (lookup_image): Port to higer-resolution time stamps.
2356 * keyboard.c (start_polling, bind_polling_period):
2357 Check for time stamp overflow.
2358 (read_char, kbd_buffer_get_event, timer_start_idle)
2359 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2360 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2361 Port to higher-resolution time stamps. Do not assume time_t is signed.
2362 (decode_timer): New function. Timers are now vectors of length 9,
2363 not 8, to accommodate the picosecond component.
2364 (timer_check_2): Use it.
2366 * nsterm.m (select_timeout, timeval_subtract): Remove.
2367 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2368 as they're a bit more accurate and handle overflow better.
2369 (ns_select): Change prototype to be compatible with pselect.
2370 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2371 * nsterm.h (ns_select): Adjust prototype.
2373 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2374 us-resolution time stamps.
2375 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2377 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2379 * lisp.h (time_overflow): New decl.
2380 (wait_reading_process_output): First arg is now intmax_t, not int,
2381 to accommodate larger waits.
2383 * process.h (struct Lisp_Process.read_output_delay):
2384 Now counts nanoseconds, not microseconds.
2385 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2386 EMACS_HAS_USECS.
2387 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2388 (wait_reading_process_output):
2389 Port to ns-resolution time stamps.
2390 (Faccept_process_output, wait_reading_process_output):
2391 Check for time stamp overflow. Do not assume time_t is signed.
2392 (select_wrapper): Remove; we now use pselect.
2393 (Fprocess_attributes): Now generates ns-resolution time stamps.
2395 * sysdep.c: Include utimens.h. Don't include utime.h
2396 or worry about struct utimbuf; gnulib does that for us now.
2397 (gettimeofday): Remove; gnulib provides a substitute.
2398 (make_timeval): New function.
2399 (set_file_times): Now sets ns-resolution time stamps.
2400 New arg FD; all uses changed.
2401 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2402 (system_process_attributes):
2403 Now returns ns-resolution time stamp. All uses changed.
2404 Check for time stamp overflow.
2406 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2407 provides a substitute now.
2409 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2410 since it guarantees struct timespec.
2411 (EMACS_TIME): Now struct timespec, so that we can support
2412 ns-resolution time stamps.
2413 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2414 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2415 (EMACS_USECS): Remove.
2416 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2417 so multiply the arg by 1000 before storing it.
2418 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2419 New macros.
2420 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2421 Port to ns-resolution time stamps.
2422 (EMACS_TIME_NEG_P): Remove; replaced by....
2423 (EMACS_TIME_SIGN): New macro.
2424 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2425 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2426 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2427 (make_timeval, make_lisp_time, decode_time_components): New decls.
2428 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2429 that it mishandled time_t overflow. You can't compare by subtracting!
2430 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2431 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2433 * term.c: Include <sys/time.h>.
2434 (timeval_to_Time): New function, for proper overflow wraparound.
2435 (term_mouse_position, term_mouse_click): Use it.
2437 * undo.c (record_first_change): Support higher-resolution time stamps
2438 in the undo buffer.
2439 (Fprimitive_undo): Use them when restoring time stamps.
2441 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2442 (w32_get_internal_run_time):
2443 Port to higher-resolution Emacs time stamps.
2444 (ltime): Now accepts single 64-bit integer, as that's more convenient
2445 for callers.
2447 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2449 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2450 for compatibility with pselect. Support ns-resolution time stamps.
2452 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2454 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2455 Check for time stamp overflow, and support ns-resolution time stamps.
2457 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2458 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2459 (timeval_subtract): Remove; no longer needed.
2460 (XTflash, XTring_bell, x_wait_for_event):
2461 Port to ns-resolution time stamps. Don't assume time_t is signed.
2463 2012-06-22 Chong Yidong <cyd@gnu.org>
2465 * xdisp.c (x_consider_frame_title): Revert last change.
2467 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2469 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2470 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2471 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2472 staticidx goes up to 1597 out of 1600 = 0x640.)
2474 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2476 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2477 Otherwise, the umask might be mistakenly 0 while handling input signals.
2479 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2481 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

2487 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2488 access to `contents' member of Lisp_Vector objects with AREF and ASET
2489 where appropriate.
2491 2012-06-19 Chong Yidong <cyd@gnu.org>
2493 * frame.c (delete_frame): When selecting a frame on a different
2494 text terminal, do not alter the terminal's top-frame.

2497 frame's selected window and its terminal's top-frame.
2498 (unwind_format_mode_line): Restore them.
2499 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2500 Callers changed.
2501 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2502 since tty frames can be explicitly named.
2503 (prepare_menu_bars): Likewise.
2505 * term.c (Ftty_top_frame): New function.
2507 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2509 Port byte-code-meter to modern targets.
2510 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2511 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2512 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2513 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2514 (METER_1, METER_2): Simplify.
2516 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2518 * data.c (Fdefalias): Return `symbol' (bug#11686).
2520 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2522 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2523 gets killed during executing of this function (Bug#11665).
2524 Try to always return Qt when the buffer has been actually killed.
2525 (Vkill_buffer_query_functions): In doc-string say that functions
2526 run by this hook should not change the current buffer.
2528 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2530 Fix recently-introduced process.c problems found by static checking.
2531 * process.c (write_queue_push, write_queue_pop, send_process):
2532 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.

2534 (send_process): Remove unused local.
2536 2012-06-17 Chong Yidong <cyd@gnu.org>

2539 frames that are not on top.
2541 2012-06-17 Troels Nielsen <bn.troels@gmail.com>

2546 writes (Bug#10815).
2548 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2550 * lisp.h (eassert): Assume C89 or later.
2551 This removes the need for CHECK.
2552 (CHECK): Remove. Its comments about always evaluating its
2553 argument were confusing, as 'eassert' typically does not evaluate
2554 its argument.
2556 * coding.c (produce_chars): Use ptrdiff_t, not int.
2558 * xterm.c (x_draw_underwave): Check for integer overflow.
2559 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2653 If all the glyphs of the glyph row came from strings, and we have no
2654 cursor positioning clues, put the cursor on the first glyph of the
2655 row.

2732 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2733 * alloc.c (make_number) [!defined make_number]:

2743 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2744 code works fine either way, and efficiency is not a concern here,
2745 as the union type is for debugging, not for production.
2746 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2747 Use an inline function on all platforms when using the union type,
2748 since this is simpler and 'static inline' can be used portably
2749 within Emacs now.
2750 (LISP_INITIALLY_ZERO): New macro.
2751 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2752 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

2834 * xdisp.c (vmessage): Treat frame message as multibyte.
2835 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2836 would generate the diagnostic "Making \302\247 buffer-local while
2837 let-bound!".
2839 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2841 * dispnew.c (showing_window_margins_p): Undo last change, which
2842 was done due to an inadvertent commit.

2855 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2857 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2859 * alloc.c (allocate_vectorlike): Fix last change.

2888 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2890 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2892 * doprnt.c (doprnt): Truncate multibyte char correctly.
2893 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2894 would mishandle a string argument "Xc" if X was a multibyte
2895 character of length 2: it would truncate after X's first byte
2896 rather than including all of X.
2898 2012-06-06 Chong Yidong <cyd@gnu.org>
2900 * buffer.c (word_wrap): Doc fix.

2947 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2949 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2950 Convert pctcpu and pctmem to Lisp float properly.
2951 Let the compiler fold better, as 100.0/0x8000 is exact.
2953 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2955 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2956 cons_block.

2962 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2964 For a 'struct window', replace some Lisp_Object fields to
2965 bitfields where appropriate, remove unused fields.
2966 * window.h (struct window): Remove unused 'last_mark_x' and
2967 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2968 change it's type from Lisp_Object to bitfield.
2969 Change type of 'force_start', 'optional_new_start',
2970 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2971 fields from Lisp_Object to bitfield. Adjust users accordingly.
2973 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2975 Pacify gcc -Wdouble-precision when using Xaw.
2976 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2977 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2978 Use 'float' consistently, rather than 'float' in most places
2979 and 'double' in a couple of places.
2981 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2983 * xdisp.c (handle_stop): Detect whether we have overlay strings
2984 loaded by testing it->current.overlay_string_index to be
2985 non-negative, instead of checking whether n_overlay_strings is
2986 positive. (Bug#11587)
2988 2012-05-31 Chong Yidong <cyd@gnu.org>
2990 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

2994 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2996 * search.c (search_buffer): Remove calls to
2997 r_alloc_inhibit_buffer_relocation, as it is now called by
2998 maybe_unify_char, which was the cause of relocation of buffer text
2999 in bug#11519.
3001 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3003 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3004 for the duration of call to load_charset, to avoid problems with
3005 callers of maybe_unify_char that access buffer text through C
3006 pointers.
3008 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3009 decrement the inhibition flag, instead of just setting or
3010 resetting it.
3012 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3014 Remove obsolete '#define static' cruft.
3015 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3016 This #undef was "temporary" in 2000; it is no longer needed
3017 now that '#define static' has gone away.
3018 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3019 (gray_bitmap_bits): Remove; no longer needed.
3020 All uses replaced with definiens.
3021 * xterm.c: Include "bitmaps/gray.xbm".
3023 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

3028 Define only on platforms that need it.
3029 * emacs.c: Include <sys/gmon.h> when profiling.
3030 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3031 (__executable_start): Remove decl, since lisp.h does it now.
3032 (safe_bcopy): Remove decl; no longer has that name.
3033 (main): Coalesce #if into single bit of code, for simplicity.
3034 Cast pointers to uintptr_t, since standard libraries want integers
3035 and not pointers.
3036 * lisp.h (__executable_start): New decl.
3038 2012-05-31 Glenn Morris <rgm@gnu.org>
3040 * image.c (Fimagemagick_types): Doc fix.

3063 Do not create empty overlays with the evaporate property (Bug#9642).
3064 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3065 Bug#9642, but explicitly check that the buffer the overlay would
3066 be moved to is live and rearrange lines to make sure that errors
3067 will not put the overlay in an inconsistent state.
3068 (Fdelete_overlay): Cosmetics.
3070 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3072 * w32term.c (my_bring_window_to_top): New function.
3073 (x_raise_frame): Use handle returned by DeferWindowPos, which
3074 could be different from the original one.

3084 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3086 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3087 This avoids undefined behavior that might cause the eassert
3088 to not catch an out-of-range value.
3090 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3092 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3106 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3107 Only r_alloc_inhibit_buffer_relocation needed to be added;
3108 the others were already declared.
3110 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3111 before checking whether it's out of range. Put the check inside
3112 eassert. See
3113 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3115 2012-05-27 Ken Brown <kbrown@cornell.edu>
3117 * callproc.c (Fcall_process): Restore a line that was accidentally
3118 commented out in the 2011-02-13 change (bug#11547).

3122 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3123 defined on ralloc.c.
3125 * buffer.c [REL_ALLOC]: Remove prototypes of
3126 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3127 they are now on lisp.h.
3129 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3131 * search.c (search_buffer): Use it to inhibit relocation of buffer
3132 text while re_search_2 is doing its job, because re_search_2 is
3133 passed C pointers to buffer text. (Bug#11519)
3135 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3136 Update value to 24.
3138 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3139 state after an additional call to move_it_in_display_line_to, keep
3140 the values of it->max_ascent and it->max_descent found for the
3141 entire line.
3142 (pos_visible_p): Revert the comparison against bottom_y to what it
3143 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3144 (Bug#11464)
3146 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3148 Fix coding-related core dumps with gcc -ftrapv.
3149 The code was computing A - B, where A and B are pointers, and B is
3150 random garbage. This can lead to core dumps on platforms that
3151 have special pointer registers, and it also leads to core dumps on
3152 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3153 A - B only when B is initialized properly.
3154 * coding.c (coding_set_source, coding_set_destination): Return void.
3155 (coding_change_source, coding_change_destinations): New functions,
3156 with the old behaviors of coding_set_source and coding_set_destination.
3157 All callers that need an offset changed to use these new functions.
3159 2012-05-26 Glenn Morris <rgm@gnu.org>
3161 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

3169 * w32console.c: Include window.h.
3170 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3171 New functions.
3172 (initialize_w32_display): Initialize mouse-highlight data.
3174 * w32inevt.c: Include termchar.h and window.h.
3175 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3176 moves, call note_mouse_highlight. If help_echo changed, call
3177 gen_help_event to produce help-echo message in the echo area.
3178 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3179 highlight info.
3181 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3183 * lread.c (read1): Simplify slightly to avoid an overflow warning
3184 with GCC 4.7.0 on x86-64.
3186 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3188 * bidi.c (bidi_mirror_char): Revert last change: an int is
3189 definitely wide enough here.
3191 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3193 Fix integer width and related bugs (Bug#9874).
3194 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3195 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

3197 (compact_small_strings, Fmake_bool_vector, make_string)
3198 (make_unibyte_string, make_multibyte_string)
3199 (make_string_from_bytes, make_specified_string)
3200 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3201 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3202 (mark_vectorlike):
3203 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3204 (allocate_pseudovector):
3205 Use int, not EMACS_INT, where int is wide enough.
3206 (inhibit_garbage_collection, Fgarbage_collect):
3207 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3225 (Foverlay_recenter, last_overlay_modification_hooks_used)
3226 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3227 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3228 (validate_region): Omit unnecessary test for b <= e,
3229 since that's guaranteed by the previous test.
3230 (adjust_overlays_for_delete): Avoid pos + length overflow.
3231 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3232 (report_overlay_modification):
3233 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3234 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3236 after the EMACS_INT -> ptrdiff_t change.
3237 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3238 * buffer.h: Adjust decls to match defn changes elsewhere.

3243 not int, to avoid needless 32-bit limit on 64-bit hosts.
3244 (exec_byte_code): Use tighter memory-full test, one that checks
3245 for alloca overflow. Don't compute the address of the object just
3246 before an array, as that's not portable. Use EMACS_INT, not
3247 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3248 * callint.c (Fcall_interactively):
3249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3262 (casify_object): Avoid integer overflow when overallocating buffer.
3263 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3266 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3267 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3268 integers are now checked earlier. All uses replaced with XINT.
3269 (ccl_driver):
3270 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3271 For CCL_MapSingle, check that content and value are in int range.
3272 (ccl_driver, Fregister_code_conversion_map):
3273 Check that Vcode_version_map_vector is a vector.
3274 (resolve_symbol_ccl_program): Check that vector header is in range.
3275 Always copy the vector, so that we can check its contents reliably
3276 now rather than having to recheck each instruction as it's being
3277 executed. Check that vector words fit in 'int'.
3278 (ccl_get_compiled_code, Fregister_ccl_program)
3279 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3280 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3282 contents are in range.
3283 (Fccl_execute_on_string): Check that status is in range.
3284 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3285 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3286 Accept and return EMACS_INT, not int, because callers can pass values
3287 out of 'int' range.

3293 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3295 avoid mishandling large integers.

3306 Don't rely on undefined behavior with signed left shift overflow.
3307 Don't assume unsigned int fits into fixnum, or that fixnum fits
3308 into unsigned int. Don't require max_code to be a valid fixnum;
3309 that's not true for gb10830 4-byte on a 32-bit host. Allow
3310 invalid_code to be a cons, for the same reason. Require code_offset
3311 to be a character. Avoid int overflow if max_char is close
3312 to INT_MAX.
3313 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3314 this is intended anyway and avoids some undefined behavior.
3315 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3316 INDEX_TO_CODE_POINT, as that's what it expects.
3317 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3318 * charset.h (DECODE_CHAR): Return int, not unsigned;
3319 this is what was intended anyway, and it avoids undefined behavior.
3320 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3321 integer-overflow issues.
3322 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3323 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3324 where the argument is EMACS_INT, and this behavior is not intended.
3325 * chartab.c (Fmake_char_table, Fset_char_table_range)
3326 (uniprop_get_decoder, uniprop_get_encoder):
3327 Don't assume fixnum fits in int.
3328 * cmds.c (move_point): New function, that does the gist of
3329 Fforward_char and Fbackward_char, but does so while checking
3330 for integer overflow more accurately.
3331 (Fforward_char, Fbackward_char): Use it.
3332 (Fforward_line, Fend_of_line, internal_self_insert)
3333 (internal_self_insert):
3334 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3981 * xterm.c (x_x_to_emacs_modifiers):
3982 Don't assume EMACS_INT overflows nicely into int.
3983 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3984 may come from Lisp.
3985 (handle_one_xevent): NATNUMP can eval its arg twice.
3986 (x_connection_closed):

3989 (struct scroll_bar): Use struct vectorlike_header
3990 rather than rolling our own approximation.
3991 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3993 2012-05-25 Glenn Morris <rgm@gnu.org>
3995 * lisp.mk (lisp): Update for more files being compiled now.
3997 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3999 * lread.c: Remove `read_pure' which makes no difference.
4000 (read_pure): Remove var.
4001 (unreadpure): Remove function.
4002 (readevalloop): Don't call read_list with -1 flag.
4003 (read1, read_vector): Don't test read_pure any more.
4004 (read_list): Simplify.
4006 * fileio.c, character.h: Minor style tweaks.
4008 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
4010 * window.h (clip_changed): Remove useless declaration.
4012 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
4014 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
4015 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
4017 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4019 Remove src/m/*.
4020 This directory predates autoconf and is no longer needed nowadays.
4021 Move its few remaining bits of functionality to where they're needed.
4022 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
4023 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
4024 * m/template.h: Remove.
4025 * Makefile.in (M_FILE): Remove. All uses removed.
4026 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
4027 * lisp.h (USE_LSB_TAG):
4028 * mem-limits.h (EXCEEDS_LISP_PTR):
4029 Use VAL_MAX, not VALBITS, in #if.
4030 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4031 (EMACS_UINT): Define unconditionally now.
4032 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4033 (BITS_PER_EMACS_INT): New constants, replacing
4034 what used to be in config.h, but not useful in #if.
4035 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4036 define them any more.
4037 (VAL_MAX): New macro.
4038 (VALMASK): Use it.
4039 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4040 BITS_PER_EMACS_INT, in #if.
4041 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4042 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4043 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4044 * s/ms-w32.h (DATA_START):
4045 Move here from removed file m/intel386.h.
4046 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4047 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4049 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4051 Assume C89 or later.
4052 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
4053 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
4054 (xrealloc):
4055 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
4056 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
4057 * textprop.c, tparam.c (NULL): Remove.
4058 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
4059 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4060 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4061 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4062 * xterm.c (input_signal_count): Assume volatile works.
4064 2012-05-21 Ken Brown <kbrown@cornell.edu>
4066 * xgselect.c (xg_select): Fix first argument in call to 'select'
4067 (bug#11508).
4069 2012-05-20 Ken Brown <kbrown@cornell.edu>
4071 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4072 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4074 2012-05-19 Ken Brown <kbrown@cornell.edu>
4076 * xfns.c (x_in_use): Remove `static' qualifier.
4077 * xterm.h (x_in_use): Declare.
4078 * xgselect.c: Include xterm.h.
4079 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4080 and `display_arg' (bug#9754).
4082 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4084 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4086 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4087 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4089 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4091 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4093 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4094 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4096 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4097 reference to image_cache->refcount.
4098 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4100 2012-05-17 Juri Linkov <juri@jurta.org>
4102 * search.c (Fword_search_regexp, Fword_search_backward)
4103 (Fword_search_forward, Fword_search_backward_lax)
4104 (Fword_search_forward_lax): Move functions to isearch.el
4105 (bug#10145, bug#11381).
4107 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4109 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4111 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4113 * lread.c (init_obarray): Declare Qt and Qnil as special.
4115 2012-05-14 Glenn Morris <rgm@gnu.org>
4117 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4118 Put "libexec" before "bin", for the sake of init_callproc_1.
4120 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4122 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4124 * unexaix.c: Port to more-recent AIX compilers.
4125 (report_error, report_error_1, make_hdr, copy_sym)
4126 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4127 Make arguments const char *, not char *, to avoid violations of C
4128 standard and to fix some AIX warnings reported by Gilles Pion.
4130 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4132 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4133 already have overlays loaded.
4134 (handle_single_display_spec): Before returning without displaying
4135 fringe bitmap, synchronize the bidi iterator with the main display
4136 iterator, by calling iterate_out_of_display_property.
4137 (iterate_out_of_display_property): Detect buffer iteration by
4138 testing that it->string is a Lisp string.
4139 (get_next_display_element): When the current object is exhausted,
4140 and there's something on it->stack, call set_iterator_to_next to
4141 proceed with what's on the stack, instead of returning zero.
4142 (set_iterator_to_next): If called at the end of a Lisp string,
4143 proceed to consider_string_end without incrementing string
4144 position. Don't increment display vector index past the end of
4145 the display vector. (Bug#11417)
4146 (pos_visible_p): Don't report a position visible when move_it_to
4147 stopped at the last line of window, which happens to be scanned
4148 backwards by the bidi iteration. (Bug#11464)
4150 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4152 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4153 and right-margin display specs even if the spec is invalid or we
4154 are on a TTY, and thus unable to display on the fringes.
4155 That's because the text with the property will not be displayed anyway,
4156 so we need to signal to the caller that this is a "replacing"
4157 display spec. This fixes display when the spec is invalid or we
4158 are on a TTY.
4160 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4162 * unexaix.c (make_hdr): Fix typo in prototype.
4163 This bug broke the build on AIX. Problem reported by Gilles Pion.
4165 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4167 * keyboard.c (kbd_buffer_get_event): Read special events also in
4168 batch mode. (Bug#11415)
4170 2012-05-12 Glenn Morris <rgm@gnu.org>
4172 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4174 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4176 * lisp.mk (lisp): Add newcomment.elc.
4178 2012-05-12 Glenn Morris <rgm@gnu.org>
4180 * Makefile.in (MKDIR_P): New, set by configure.
4181 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4183 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4185 Remove unused function hourglass_started.
4186 * dispextern.h (hourglass_started):
4187 * w32fns.c (hourglass_started):
4188 * xdisp.c (hourglass_started): Remove.
4190 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4192 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4193 Update dependencies.
4195 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4197 * xgselect.c (xg_select): Put maxfds+1 into a var.
4198 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4200 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4202 2012-05-10 Dave Abrahams <dave@boostpro.com>
4204 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4205 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4207 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4209 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4210 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4211 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4212 Initialize xd_registered_buses.
4214 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4216 Untag more efficiently if USE_LSB_TAG.
4217 This is based on a proposal by YAMAMOTO Mitsuharu in
4218 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4219 For an admittedly artificial (nth 8000 longlist) benchmark on
4220 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4221 Emacs's overall text size by 1%.
4222 * lisp.h (XUNTAG): New macro.
4223 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4224 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4225 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4226 * eval.c (Fautoload):
4227 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4228 * frame.h (XFRAME): Use XUNTAG.
4230 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4231 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4232 Remove unportable assumptions about print widths of types like
4233 dbus_uint32_t.
4234 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4235 intptr_t when converting between pointer and integer, to avoid GCC
4236 warnings about wrong width.
4238 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4240 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4241 stack for each reader_thread, instead of defaulting to 8MB
4242 determined by the linker. This avoids failures in creating
4243 subprocesses on Windows 7, see the discussion in this thread:
4244 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4246 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4248 Fix up display of the *Minibuf-0* buffer in the mini window.
4249 * keyboard.c (read_char): Don't clear the echo area if there's no
4250 message to clear.
4251 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4252 contents of *Minibuf-0*) if there's no message displayed in its stead.
4254 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4256 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4257 batch mode.
4259 2012-05-06 Chong Yidong <cyd@gnu.org>
4261 * lisp.mk (lisp): Update.
4263 2012-05-05 Jim Meyering <meyering@redhat.com>
4265 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4267 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4269 * data.c (PUT_ERROR): New macro.
4270 (syms_of_data): Use it. Add new error type `user-error'.
4271 * undo.c (user_error): New function.
4272 (Fprimitive_undo): Use it.
4273 * print.c (print_error_message): Adjust print style for `user-error'.
4274 * keyboard.c (user_error): New function.
4275 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4277 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4279 Do not limit current-time-string to years 1000..9999.
4280 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4281 (Fcurrent_time_string): Support any year that is supported by the
4282 underlying localtime representation. Don't use asctime, as it
4283 has undefined behavior for years outside the range -999..9999.
4285 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4287 Fix race conditions involving setenv, gmtime, localtime, asctime.
4288 Without this fix, interrupts could mess up code that uses these
4289 nonreentrant functions, since setting TZ invalidates existing
4290 tm_zone or tzname values, and since most of these functions return
4291 pointers to static storage.
4292 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4293 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4294 Grow the critical sections to include not just invoking
4295 localtime/gmtime, but also accessing these functions' results
4296 including their tm_zone values if any, and any related TZ setting.
4297 (format_time_string): Last arg is now struct tm *, not struct tm **,
4298 so that the struct tm is saved in the critical section.
4299 All callers changed. Simplify allocation of initial buffer, partly
4300 motivated by the fact that memory allocation needs to be outside
4301 the critical section.
4303 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4305 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4306 with RESET_INTERVAL.
4308 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

4317 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4319 * xdisp.c (pos_visible_p): If already at a newline from the
4320 display string before the 'while' loop, don't walk back the glyphs
4321 from it3.glyph_row. Solves assertion violation when the display
4322 string begins with a newline (egg.el). (Bug#11367)
4324 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4326 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

4332 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4333 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4334 All were removed before 23.1.

4352 Do not avoid creating empty evaporating overlays (Bug#9642).
4353 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4354 That is, do not delete an evaporating overlay if it becomes
4355 empty after its bounds are adjusted to fit within its buffer.
4356 This fix caused other problems, and I'm reverting it until we get
4357 to the bottom of them.
4359 2012-04-27 Chong Yidong <cyd@gnu.org>
4361 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4363 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4365 * xdisp.c (pos_visible_p): If the window start position is beyond
4366 ZV, start the display from buffer beginning. Prevents assertion
4367 violation in init_iterator when the minibuffer window is scrolled
4368 via the scroll bar.
4370 * window.c (window_scroll_pixel_based): Likewise.
4372 2012-04-27 Chong Yidong <cyd@gnu.org>

4388 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4389 display element, check also the underlying string or buffer
4390 character. (Bug#11341)
4392 * w32menu.c: Include w32heap.h.
4393 (add_menu_item): If the call to AppendMenuW (via
4394 unicode_append_menu) fails, disable Unicode menus only if we are
4395 running on Windows 9X/Me.
4397 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4399 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4400 (xgetint): Add missing shift for LSB tags.
4402 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4404 * keyboard.c (read_char): Don't wipe echo area for select window
4405 events: These might get delayed via `mouse-autoselect-window'
4406 (Bug#11304).
4408 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4410 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4411 manipulation of :loaded-from data.
4413 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4415 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4416 now a cons (bug#11311).
4418 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4420 Do not create empty overlays with the evaporate property (Bug#9642).
4421 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4422 if it becomes empty after its bounds are adjusted to fit within
4423 its buffer. Without this fix, in a nonempty buffer (let ((o
4424 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4425 yields an empty overlay that has the evaporate property, which is
4426 not supposed to happen.
4428 Fix minor GTK3 problems found by static checking.
4429 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4449 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4450 (__malloc_size_t, __malloc_ptrdiff_t):
4451 Remove. All uses removed, replaced by the definiens if needed,

4463 Define using prototypes, not old style.
4464 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4465 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

4543 * sysdep.c [__FreeBSD__]: Minor cleanups.
4544 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4545 Use Emacs indenting style more consistently. Avoid some casts.

4569 2012-04-20 Chong Yidong <cyd@gnu.org>
4571 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4572 set the status to "failed" and ensure that sentinel is run.

4700 2012-04-11 Daniel Colascione <dancol@dancol.org>
4702 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4703 against is gone. It's better to use vfork now so that when Cygwin
4704 gains a new, working vfork, we use it automatically (bug#10398).
4706 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4756 (Fdefvar): Caller changed.
4758 * callint.c (Finteractive, Fcall_interactively):
4759 * minibuf.c (Fread_variable): Callers changed.
4761 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4763 * xdisp.c (set_cursor_from_row): If the display string appears in
4764 the buffer at position that is closer to point than the position
4765 after the display string, display the cursor on the first glyph of
4766 the display string. Fixes cursor display when a 'display' text
4767 property immediately follows invisible text. (Bug#11094)
4769 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4771 composite.c: use 'double' consistently
4772 * composite.c (get_composition_id): Use 'double' consistently
4773 instead of converting 'float' to 'double' and vice versa; this is
4774 easier to understand and avoids a GCC warning.
4776 2012-04-09 Glenn Morris <rgm@gnu.org>
4778 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4779 preparation for dumping it with emacs. (Bug#4789)
4780 (leimdir): New variable.
4781 ($(leimdir)/leim-list.el): New rule.
4782 (emacs$(EXEEXT)): Depend on leim-list.el.
4784 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
4785 (Fget_buffer_create): Don't call Qucs_set_table_for_input.

4795 * xml.c (init_libxml2_functions) [WINDOWSNT]:
4796 Remove unused local variable.
4798 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4800 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
4801 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4802 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4803 objects, as mark_maybe_pointer will catch them otherwise.
4804 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4805 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4807 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4809 Fix typo that broke non-Windows builds.
4810 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
4812 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4814 Support building on MS-Windows with libxml2.
4816 * makefile.w32-in (OBJ2): Add xml.$(O).
4817 (GLOBAL_SOURCES): Add xml.c.
4818 ($(BLD)/xml.$(O)): New dependency list.
4820 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
4821 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4822 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4823 [!WINDOWSNT]: New macros.
4824 (init_libxml2_functions, libxml2_loaded_p): New functions.
4825 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4826 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4827 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4828 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4829 linked in).
4830 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4831 Call init_libxml2_functions before calling libxml2 functions.
4832 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4834 * emacs.c: Don't include libxml/parser.h.
4835 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4836 xmlCleanupParser directly.
4838 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4840 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4842 * indent.c (Fvertical_motion): If there is a display string at
4843 point, use it.vpos to compute how many lines to backtrack after
4844 move_it_to point. (Bug#11133)
4846 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4848 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4849 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4850 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4851 macros related to unification of CJK characters. For the details,
4852 see the discussion following the message here:
4853 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4855 2012-04-04 Chong Yidong <cyd@gnu.org>
4857 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4859 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4861 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4862 instead of alloca. (Bug#11138)
4864 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4866 * w32menu.c (is_simple_dialog): Properly check lisp types.
4867 (Bug#11141)
4869 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4871 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4872 position we get to after a call to move_it_to fails the
4873 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4874 only if we wind up in a string from display property. (Bug#11063)
4876 * window.c (Fdelete_other_windows_internal): Invalidate the row
4877 and column information about mouse highlight, so that redisplay
4878 restores it after reallocating the glyph matrices. (Bug#7464)
4880 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4881 string comes from a `display' text property, use the buffer
4882 position of that property as if we actually saw that position in
4883 the row's glyphs.
4884 (move_it_by_lines): Remove the assertion that
4885 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4886 violated when there's a before-string at the beginning of a line.
4887 (Bug#11063)
4889 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4891 * xdisp.c (append_space_for_newline): If the default face was
4892 remapped, use the remapped face for the appended newline.
4893 (extend_face_to_end_of_line): Use the remapped default face for
4894 extending the face to the end of the line.
4895 (display_line): Call extend_face_to_end_of_line when the default
4896 face was remapped. (Bug#11068)
4898 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4900 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4902 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4904 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4906 2012-03-27 Glenn Morris <rgm@gnu.org>
4908 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4909 Doc fixes.
4911 2012-03-26 Kenichi Handa <handa@m17n.org>
4913 * dispextern.h (struct glyph): Fix previous change. Change the
4914 bit length of glyphless.ch to 25 (Bug#11082).
4916 2012-03-26 Chong Yidong <cyd@gnu.org>
4918 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4919 (command_loop_1): Use it; inhibit selection update for
4920 handle-select-window too (Bug#8996).
4922 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4924 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4926 2012-03-25 Kenichi Handa <handa@m17n.org>
4928 * dispextern.h (struct glyph): Change the bit length of
4929 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4931 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4933 * s/ms-w32.h (tzname): Include time.h before redirecting to
4934 _tzname. Fixes the MSVC build. (Bug#9960)
4936 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4938 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4939 characters.
4941 * xterm.c (XTread_socket): Only modify handling_signal if
4942 !SYNC_INPUT. (Bug#11080)
4944 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4946 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4947 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4948 when fetching a multibyte character consumes more bytes than
4949 CHAR_BYTES returns, due to unification of CJK characters in
4950 string_char. (Bug#11073)
4952 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4954 * process.c (wait_reading_process_output): Handle pty disconnect
4955 by refraining from sending oneself a SIGCHLD (bug#10933).
4957 2012-03-22 Chong Yidong <cyd@gnu.org>
4959 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4961 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4962 Mark string as coming from a prefix property.
4963 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4964 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4966 2012-03-21 Chong Yidong <cyd@gnu.org>
4968 * xfaces.c (Vface_remapping_alist): Doc fix.
4970 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4972 * w32proc.c (Fw32_set_console_codepage)
4973 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4974 Doc fixes.
4976 2012-03-20 Chong Yidong <cyd@gnu.org>
4978 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4979 to reflect default non-nil value of redisplay-dont-pause.
4981 2012-03-19 Kenichi Handa <handa@m17n.org>
4983 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4984 it fit in a valid range (Bug#11003).
4986 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4988 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4989 that is not from display property, accept the row as a "cursor
4990 row" if one of the string's character has a non-nil `cursor'
4991 property. Fixes cursor positioning when there are newlines in
4992 overlay strings, e.g. in icomplete.el. (Bug#11035)
4994 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4996 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4998 2012-03-12 Chong Yidong <cyd@gnu.org>
5000 * eval.c (inhibit_lisp_code): Rename from
5001 inhibit_window_configuration_change_hook; move from window.c.
5003 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5004 * window.c (run_window_configuration_change_hook)
5005 (syms_of_window): Callers changed.
5007 2012-03-11 Chong Yidong <cyd@gnu.org>
5009 * keymap.c (Fkey_description): Doc fix (Bug#9700).

5015 * frame.c (other_visible_frames): Don't assume the selected frame
5016 is visible (Bug#10955).
5018 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5020 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5022 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5024 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5025 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5026 zero (Bug#10954).
5028 2012-03-03 Glenn Morris <rgm@gnu.org>
5030 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5032 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5034 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5035 position past the first glyph_row that ends at ZV. (Bug#10902)
5036 (redisplay_window, next_element_from_string): Fix typos in
5037 comments.
5038 (redisplay_window): Pass to move_it_vertically the margin in
5039 pixels, not in screen lines.
5041 2012-03-02 Glenn Morris <rgm@gnu.org>
5043 * buffer.c (buffer-list-update-hook): Doc fix.
5045 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5047 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5048 push_it before setting up the iterator for the first overlay
5049 string, even if we have an empty string loaded.
5050 (next_overlay_string): If there's an empty string on the iterator
5051 stack, pop the stack. (Bug#10903)
5053 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5055 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5056 Suggested by Stefan Monnier in
5057 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5058 * alloc.c (widen_to_Lisp_Object): New static function.
5059 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5060 and widening them to Lisp_Objects. This would work even if
5061 USE_LSB_TAG is defined and wide integers are used, which might
5062 happen in a future version of Emacs.
5064 2012-02-25 Chong Yidong <cyd@gnu.org>
5066 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5067 Doc fix.
5069 * xselect.c (Fx_selection_exists_p): Doc fix.
5070 (x_clipboard_manager_save_all): Print an informative message
5071 before saving to clipboard manager.
5073 2012-02-24 Chong Yidong <cyd@gnu.org>
5075 * keyboard.c (process_special_events): Handle all X selection
5076 requests in kbd_buffer, not just the next one (Bug#8869).
5078 2012-02-23 Chong Yidong <cyd@gnu.org>
5080 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5081 call when setting menu-bar-lines and tool-bar-lines parameters.
5082 (unwind_create_frame_1): New helper function.
5084 * window.c (inhibit_window_configuration_change_hook): New var.
5085 (run_window_configuration_change_hook): Obey it.
5086 (syms_of_window): Initialize it.
5088 2012-02-22 Chong Yidong <cyd@gnu.org>
5090 * xterm.c (x_draw_image_relief): Add missing type check for
5091 Vtool_bar_button_margin (Bug#10743).
5093 2012-02-21 Chong Yidong <cyd@gnu.org>
5095 * fileio.c (Vfile_name_handler_alist): Doc fix.
5097 * buffer.c (Fget_file_buffer): Protect against invalid file
5098 handler return value.
5100 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5102 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5103 when computing $valmask.
5105 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5106 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5107 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5108 It's useless in that case, and it can cause problems on hosts
5109 that allocate halves of EMACS_INT values separately.
5110 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5111 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5112 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5113 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5114 it avoids undefined behavior on hosts where shifting right by more
5115 than the word width has undefined behavior.
5117 2012-02-19 Chong Yidong <cyd@gnu.org>
5119 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5120 (Funhandled_file_name_directory, Ffile_name_as_directory)
5121 (Fdirectory_file_name, Fexpand_file_name)
5122 (Fsubstitute_in_file_name): Protect against invalid file handler
5123 return values (Bug#10845).
5125 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5127 * .gdbinit (pitx): Fix incorrect references to fields of the
5128 iterator stack.
5130 2012-02-17 Chong Yidong <cyd@gnu.org>
5132 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5134 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5136 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5137 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5139 2012-02-15 Chong Yidong <cyd@gnu.org>
5141 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5142 marked as special. Also, starting docstrings with * is obsolete.
5144 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5146 * gnutls.c (emacs_gnutls_write): Fix last change.
5148 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
5150 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
5151 send_process.
5153 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5155 * keymap.c (Fsingle_key_description): Handle char ranges.
5157 2012-02-12 Chong Yidong <cyd@gnu.org>
5159 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5160 as that creates a dangerous corner case.
5162 * window.c (Fdelete_window_internal): Invalidate the mouse
5163 highlight (Bug#9904).
5165 2012-02-12 Glenn Morris <rgm@gnu.org>
5167 * xselect.c (Fx_own_selection_internal)
5168 (Fx_get_selection_internal, Fx_disown_selection_internal)
5169 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5170 * nsselect.m (Fx_own_selection_internal)
5171 (Fx_disown_selection_internal, Fx_selection_exists_p)
5172 (Fx_selection_owner_p, Fx_get_selection_internal):
5173 Sync docs and argument specs with the xselect.c versions.
5175 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5177 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5179 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5181 * w32select.c (Fx_selection_exists_p): Sync doc string and
5182 argument list with xselect.c. (Bug#10783)
5184 * w16select.c (Fx_selection_exists_p): Sync doc string and
5185 argument list with xselect.c. (Bug#10783)

5195 2012-02-07 Chong Yidong <cyd@gnu.org>
5197 * buffer.c (Fbuffer_local_variables)
5198 (buffer_lisp_local_variables): Handle unbound vars correctly;
5199 don't let Qunbound leak into Lisp.
5201 2012-02-07 Glenn Morris <rgm@gnu.org>
5203 * image.c (Fimagemagick_types): Doc fix.
5205 * image.c (imagemagick-render-type): Change it from a lisp object
5206 to an integer. Move the doc here from the lisp manual.
5207 Treat all values not equal to 0 the same.
5209 2012-02-06 Chong Yidong <cyd@gnu.org>
5211 * doc.c (store_function_docstring): Avoid applying docstring of
5212 alias to base function (Bug#2603).
5214 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5216 * .gdbinit (pp1, pv1): Remove redundant defines.
5217 (pr): Use pp.
5219 2012-02-04 Chong Yidong <cyd@gnu.org>
5221 * nsterm.m: Declare a global (Bug#10694).
5223 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5225 * w32.c (get_emacs_configuration_options):
5226 Include --enable-checking, if specified, in the return value.
5228 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5230 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5231 after rounding frame sizes. (Bug#9723)
5233 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5235 * keyboard.c (adjust_point_for_property): Don't position point
5236 before BEGV. (Bug#10696)
5238 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5240 Handle overflow when computing char display width (Bug#9496).
5241 * character.c (char_width): Return EMACS_INT, not int.
5242 (char_width, c_string_width): Check for overflow when
5243 computing the width; this is possible now that individual

5732 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
5733 verifies glyph row's hash code--we have just reallocated the
5734 glyphs, so their contents can be complete garbage. (Bug#10164)
5736 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
5738 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.

5742 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
5743 attributes are tested _before_ calling verify_row_hash, to protect
5744 against GCC re-ordering of the tests. (Bug#10164)
5746 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>
5748 * xterm.h (struct x_output): net_wm_state_hidden_seen is new.

5751 if net_wm_state_hidden_seen is non-zero (Bug#10002)
5752 (get_current_wm_state): Set net_wm_state_hidden_seen to 1 if
5753 _NET_WM_STATE_HIDDEN is in NET_WM_STATE.
5755 2011-11-28 Paul Eggert <eggert@cs.ucla.edu>

5767 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
5768 of scroll runs so as to avoid assigning disabled bogus rows and
5769 unnecessary graphics copy operations.
5771 2011-11-27 Eli Zaretskii <eliz@gnu.org>
5773 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
5774 (snprintf) [_MSC_VER]: Redirect to _snprintf.
5775 (strtoll) [_MSC_VER]: Redirect to _strtoi64.
5776 (malloc, free, realloc, calloc): Redirect to e_* only when
5777 compiling Emacs.
5779 * lisp.h (GCTYPEBITS): Move before first use.
5780 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
5781 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
5782 this macro definition.
5784 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
5785 _MSC_VER.
5787 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>
5789 * gtkutil.c (xg_create_frame_widgets):
5790 Call gtk_window_set_has_resize_grip (FALSE) if that function is
5791 present with Gtk+ 2.0.
5793 2011-11-26 Paul Eggert <eggert@cs.ucla.edu>
5795 * fileio.c (Finsert_file_contents): Undo previous change; see
5796 <http://lists.gnu.org/archive/html/emacs-diffs/2011-11/msg00265.html>.

5805 Indent for consistency with usual Emacs style.
5807 2011-11-25 Eli Zaretskii <eliz@gnu.org>
5809 * xdisp.c (redisplay_window): If cursor row is not fully visible
5810 after recentering, and scroll-conservatively is set to a large
5811 number, scroll window by a few more lines to make the cursor fully
5812 visible and out of scroll-margin. (Bug#10105)
5813 (start_display): Don't move to the next line if the display should
5814 start at a newline that is part of a display vector or an overlay
5815 string. (Bug#10119)
5817 2011-11-24 Juri Linkov <juri@jurta.org>

5842 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
5843 and header-lines, as they don't have one computed for them.
5844 (Bug#10098)
5846 * .gdbinit (prow): Make displayed values more self-explaining.
5847 Add row's hash code.

5892 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
5894 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
5895 Otherwise, valgrind does not work on some platforms.
5896 Problem reported by Andreas Schwab in
5897 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5898 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5899 is set, removing the need for VIRT_ADDRESS_VARIES.
5900 (PURE_P): Use a more-efficient implementation that needs just one
5901 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5902 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5903 to 4 (xorl, subq, cmpq, setbe).
5904 * alloc.c (pure): Always extern now, since that's the
5905 VIRT_ADDR_VARIES behavior.
5906 (PURE_POINTER_P): Use a single comparison, not two, for
5907 consistency with the new puresize.h.
5908 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5909 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

5915 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5916 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5917 behave as if the cursor position were at the window margin.
5919 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5920 and the cursor position is out of bounds, behave as if the cursor
5921 position were at the window margin. (Bug#10075)
5923 2011-11-18 Chong Yidong <cyd@gnu.org>
5925 * window.c (Fwindow_combination_limit): Make first argument
5926 non-optional, since it is meaningless for live windows like the
5927 selected window.

5940 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
5941 hash values of the two rows.
5942 (copy_row_except_pointers): Preserve the used[] arrays and the
5943 hash values of the two rows. (Bug#10035)
5944 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5946 * xdisp.c (row_hash): New function, body extracted from
5947 compute_line_metrics.
5948 (compute_line_metrics): Call row_hash, instead of computing the
5949 hash code inline.
5951 * dispnew.c (verify_row_hash): Call row_hash for computing the
5952 hash code of a row, instead of duplicating code from xdisp.c.
5954 * dispextern.h (row_hash): Add prototype.
5956 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
5958 * frame.c (delete_frame): Don't delete the terminal when the last

5980 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
5981 (Fset_window_nest): Rename to Fset_window_combination_limit.
5982 (Vwindow_nest): Rename to Vwindow_combination_limit.
5983 (recombine_windows, make_parent_window, make_window)
5984 (Fsplit_window_internal, saved_window)
5985 (Fset_window_configuration, save_window_save): Rename all
5986 occurrences of window_nest to window_combination_limit.
5988 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
5990 * image.c (imagemagick_load_image): Fix typo.
5992 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5994 * xdisp.c (display_line): Move the call to
5995 highlight_trailing_whitespace before the call to
5996 compute_line_metrics, since the latter needs to see the final
5997 faces of all the glyphs to compute ROW's hash value.
5998 Fixes assertion violations in row_equal_p. (Bug#10035)
6000 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6002 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
6003 just return (bug#10044).
6005 2011-11-12 Eli Zaretskii <eliz@gnu.org>
6007 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6008 with user-defined heap size. Bump the default size of the temacs
6009 heap to 27MB, to avoid memory warning when running temacs.
6010 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6012 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
6013 current_matrix and desired_matrix. (Bug#9990)
6014 (verify_row_hash) [XASSERTS]: New function.
6015 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
6016 that the hash value of glyph rows is correct.
6018 2011-11-12 Martin Rudalics <rudalics@gmx.at>
6020 * window.h (window): Remove splits slot.

6029 2011-11-11 Jan Djärv <jan.h.d@swipnet.se>
6031 * xfns.c (unwind_create_frame):
6032 * nsfns.m (unwind_create_frame):
6033 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
6034 Vframe_list (Bug#9999).

6045 2011-11-11 Johan Bockgård <bojohan@gnu.org>
6047 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
6048 avoid a crash (bug#9496).
6050 2011-11-09 Chong Yidong <cyd@gnu.org>
6052 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

6059 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6061 Avoid some portability problems by eschewing 'extern inline' functions.
6062 The trivial performance wins aren't worth the portability hassles; see
6063 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6064 et seq.
6065 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6066 (window_box_width, window_box_left, window_box_left_offset)
6067 (window_box_right, window_box_right_offset): Undo previous change,
6068 by removing the "extern"s.
6069 * intervals.c (adjust_intervals_for_insertion)
6070 (adjust_intervals_for_deletion): Undo previous change,
6071 making these static again.
6072 (offset_intervals, temp_set_point_both, temp_set_point)
6073 (copy_intervals_to_string): No longer inline.
6074 * xdisp.c (window_text_bottom_y, window_box_width)

6113 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6114 This is also needed for porting to any host where GC_MARK_STACK is
6115 not GC_MAKE_GCPROS_NOOPS.
6116 (which_symbols): Use it.
6118 2011-11-07 Kenichi Handa <handa@m17n.org>

6129 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6131 * xmenu.c (cleanup_widget_value_tree): New function.
6132 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
6133 calling free_menubar_widget_value_tree directly (Bug#9830).
6135 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6137 Fix some portability problems with 'inline'.
6138 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6139 (window_box_width, window_box_left, window_box_left_offset)
6140 (window_box_right, window_box_right_offset): Declare extern.
6141 Otherwise, these inline functions do not conform to C99 and
6142 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6143 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6144 * intervals.c (adjust_intervals_for_insertion)
6145 (adjust_intervals_for_deletion): Now extern, because otherwise the
6146 extern inline functions 'offset_intervals' couldn't refer to it.
6147 (static_offset_intervals): Remove.
6148 (offset_intervals): Rewrite using the old contents of
6149 static_offset_intervals. The old version didn't conform to C99
6150 because an extern inline function contained a reference to an
6151 identifier with static linkage.
6153 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6155 * keyboard.c (interrupt_signal): Don't call kill-emacs while in
6156 GC.

6171 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
6172 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6173 (Fwindow_vscroll): Doc fix.
6174 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6175 argument, since it makes no sense to pass a live window and for
6176 consistency with window-child.

6257 * xdisp.c (note_mouse_highlight): If either of
6258 previous/next-single-property-change returns nil, treat that as
6259 the beginning or the end of the buffer. (Bug#9955)
6261 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6263 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

6281 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6283 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6284 Don't stop backward scan on the continuation glyph, even though

6287 Rename cover_string to disp_string.
6289 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6291 * window.c (temp_output_buffer_show): Don't use
6292 Vtemp_buffer_show_specifiers.
6293 (Vtemp_buffer_show_specifiers): Remove unused variable.
6295 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6297 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented

6323 so that this new function doesn't get optimized away by a
6324 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6326 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6328 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6330 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6344 line. (Bug#9903)
6346 2011-10-29 Glenn Morris <rgm@gnu.org>
6348 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6349 Not clear what it was for, and it causes various bugs. (Bug#9839)
6351 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6353 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6354 possible random value that matches one of those tested as
6355 condition to clear the mouse face.
6357 2011-10-28 Chong Yidong <cyd@gnu.org>
6359 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6363 * window.c (make_window): Initialize phys_cursor_on_p.
6365 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6367 * lisp.h (struct Lisp_Symbol): Update comments.
6369 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6371 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6373 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6375 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6376 <oslsachem@gmail.com> for helping to debug this.
6378 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

6384 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6385 New functions.
6386 (w32font_open_internal, compute_metrics):
6387 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6388 instead of calling the "wide" APIs directly.
6390 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6392 * w32.h (syms_of_w32font): Add prototype.
6394 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6396 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6397 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6398 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6399 (Fmove_to_window_line): Doc fix.
6401 2011-10-27 Chong Yidong <cyd@gnu.org>
6403 * process.c (make_process): Set gnutls_state to NULL.
6405 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6406 non-NULL, regardless of GNUTLS_INITSTAGE.
6407 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6408 an error. Set process slots as soon as we allocate them.
6410 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6412 2011-10-27 Chong Yidong <cyd@gnu.org>

6416 (Fgnutls_deinit, Fgnutls_boot): Use it.
6418 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6419 (deactivate_process): Call emacs_gnutls_deinit.
6421 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6431 extracted from Fw32_default_color_map.
6432 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6434 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6436 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6438 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6440 * keyboard.c (test_undefined): New function (bug#9751).
6441 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6443 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6445 * sysdep.c (init_sys_modes): Fix the check for the controlling
6446 terminal (Bug#6649).
6448 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6450 * dispextern.h (struct bidi_it): New member next_en_type.
6452 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6453 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6454 current character, check also for next_en_type being WEAK_EN.
6455 (bidi_resolve_weak): Don't enter the expensive loop if the current
6456 position is before next_en_pos. Record the bidi type of the first
6457 non-ET, non-BN character we find, in addition to its position.
6458 (bidi_level_of_next_char): Invalidate next_en_type when
6459 next_en_pos is over-stepped.
6461 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6463 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6464 * editfns.c: Rewrite current-time-zone so that it invokes
6465 the equivalent of (format-time-string "%Z") to get the time zone name.
6466 This fixes a bug when the time zone name contains characters that
6467 need converting from the system time locale to Emacs internal format.
6468 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6469 that patch fixed format-time-string to do the conversion, but
6470 I forgot to fix current-time-zone.
6471 (format_time_string): New function, containing most of
6472 what Fformat_time_string used to contain.
6473 (Fformat_time_string): Rewrite in terms of format_time_string.
6474 This doesn't change this function's behavior.
6475 (current-time-zone): Rewrite to use format_time_string.
6476 This fixes the bug reported by Michael Schierl in
6477 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6478 Jason Rumney's 2007-06-07 change worked around this bug, but
6479 didn't fix it.
6480 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6482 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6484 * xdisp.c (start_display): If the character at POS is displayed
6485 via a display vector, reset IT->current.dpvec_index to zero.
6486 (try_window_reusing_current_matrix): If a line ends in a display
6487 vector or the next line starts in a display vector, continue
6488 redrawing the window even though the character position of
6489 start_row was reached.
6490 (Bug#9771, part 2)
6492 2011-10-18 Chong Yidong <cyd@gnu.org>
6494 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6495 with nobreak-char-display too.
6497 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6499 Fix part 3 of bug#9771.
6500 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6501 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6502 non-neutral characters if the current character is a paragraph
6503 separator (a.k.a. Newline). This avoids running the same
6504 expensive loop twice, once when we consume the preceding newline
6505 and the other time when the line actually needs to be displayed.
6506 Avoid the loop when we see neutrals on the base embedding level
6507 following a character whose directionality is the same as the
6508 paragraph's. This avoids running the expensive loop when a line
6509 ends in a long sequence of neutrals, like control characters.
6510 Add assertion against STRONG_AL type. Slightly rearrange code
6511 that determines the type of a neutral given the first non-neutral
6512 that follows it.
6513 (bidi_level_of_next_char): Set next_en_pos to zero when
6514 invalidating its info.
6516 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6518 * xdisp.c (push_display_prop): Determine whether to record string
6519 or buffer position by IT->string, not by IT->method. Allow
6520 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6521 (move_it_vertically_backward): Don't look for character position
6522 immediately after the newline when in a continuation line.
6523 (Bug#9771, part 1)
6525 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6527 * window.c (coordinates_in_window): Rewrite and delabelize
6528 vertical border check. (Bug#5357) (Bug#9618)
6530 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6532 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6533 errors in XSetWindowBorder (bug#9310).
6535 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6537 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6538 avoid crash when xmalloc overrun checking is enabled.
6540 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6542 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6543 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6544 cursor motion with <left> and <right> arrow keys.
6546 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6547 some callers set that themselves.
6549 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6551 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6552 display string and the previous row comes from the same string and
6553 is empty. (Bug#9739) (Bug#9738)
6555 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6557 * doc.c (get_doc_string): Encode file name (bug#9735).
6559 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6561 * bidi.c (bidi_level_of_next_char):
6562 * xdisp.c (get_visually_first_element): Remove old incorrect
6563 comments regarding the Unicode Line Separator character.
6565 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6567 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6569 * alloc.c (Fgc_status): Do not access beyond zombies array
6570 boundary if nzombies > MAX_ZOMBIES.
6571 * alloc.c (dump_zombies): Add missing format specifier.
6573 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6575 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6576 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6578 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6579 Some packages use them to denote characters with modifiers.
6581 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6583 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6584 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6585 matching a pp-number. Rename parameter var to var1.
6587 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6589 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6591 2011-10-08 Glenn Morris <rgm@gnu.org>
6593 * callint.c (Fcall_interactively): Give a more explicit error for the
6594 'c' case with a non-character input. (Bug#8479)
6596 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6598 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6599 lines.
6600 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6601 lines that are hscrolled on the left.
6603 * dispnew.c (buffer_posn_from_coords): Account for a possible
6604 presence of header-line. (Bug#4426)
6606 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6608 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6609 Don't advertise functionality which we discourage or doesn't work.
6611 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6613 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6614 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6615 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6616 this makes Emacs dump core during garbage collection on rare
6617 occasions. sizeof is obviously inferior to offsetof here, so
6618 stick with offsetof.
6619 (GC_POINTER_ALIGNMENT): New macro.
6620 (mark_memory): Omit 3rd (offset) arg; caller changed.
6621 Don't assume EMACS_INT alignment is the same as pointer alignment.
6623 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6625 * keyboard.c (read_key_sequence_remapped): New var.
6626 (read_key_sequence): Compute remapping in the right buffer.
6627 (command_loop_1): Use read_key_sequence's remapping directly.
6629 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6631 * dired.c (file_name_completion): Don't expand file name.
6632 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6633 before checking file name handler.
6635 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6636 they've been requested explicitly (bug#9591).
6638 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6640 * keymap.c (Fsingle_key_description): Use make_specified_string
6641 instead of build_string to build string from push_key_description.
6642 (Bug#5193)
6644 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6646 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6647 This fixes a Y2038 bug on 64-bit hosts.
6648 * buffer.c (reset_buffer):
6649 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6650 (Fclear_buffer_auto_save_failure):
6651 Use 0, not -1, to represent an unset failure time, since time_t
6652 might not be signed.
6654 Remove dependency on glibc malloc internals.
6655 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6656 Move back here from lisp.h, but with their new implementations.
6657 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6658 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6659 * charset.c (charset_table_init): New static var.
6660 (syms_of_charset): Use it instead of xmalloc. This removes a
6661 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6662 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6663 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6664 Move back to alloc.c.
6665 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6666 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6668 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6670 * nsterm.m (windowDidResize): Call x_set_window_size only when
6671 ns_in_resize is true. Otherwise set pixelwidth/height and
6672 call change_frame_size (Bug#9628).
6674 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6676 Port --enable-checking=all to Fedora 14 x86-64.
6677 * charset.c (syms_of_charset): Also account for glibc malloc's
6678 internal overhead when calculating the initial malloc maximum.
6680 Port --enable-checking=all to Fedora 14 x86.
6681 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6682 Move to lisp.h.
6683 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6684 (overrun_check_realloc, overrun_check_free):
6685 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6686 That way, xmalloc returns a properly-aligned pointer even if
6687 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6688 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6689 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6690 into account when calculating the initial malloc maximum.
6691 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6692 Move here from alloc.c, so that charset.c can use it too.
6693 Properly align; the old code wasn't right for common 32-bit hosts
6694 when configured with --enable-checking=all.
6695 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6696 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6698 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6700 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6701 use EDOM.
6703 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6705 * xdisp.c (compute_display_string_end): If there's no display
6706 string at CHARPOS, return -1.
6708 * bidi.c (bidi_fetch_char): When compute_display_string_end
6709 returns a negative value, treat the character as a normal
6710 character not covered by a display string. (Bug#9624)
6712 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6714 * lread.c (Fread_from_string): Fix typo in docstring.
6716 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6718 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6719 newline, reseat the iterator instead of bidi-iterating there one
6720 character at a time. (Bug#9610)
6721 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6722 TO_CHARPOS if the bidi iterator is at base embedding level.
6724 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6726 * lread.c (readevalloop): Use correct code for NBSP.
6727 (read1): Likewise. (Bug#9608)
6729 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6731 * dbusbind.c (Fdbus_register_signal): When service is not
6732 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6734 2011-09-25 Glenn Morris <rgm@gnu.org>
6736 * buffer.c (truncate-lines): Doc fix.
6738 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6740 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6741 (Fset_window_next_buffers): Doc fix.
6743 2011-09-24 Glenn Morris <rgm@gnu.org>
6745 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6747 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6749 Fix minor problems found by static checking.
6750 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6751 * indent.c (Fvertical_motion): Fix == vs = typo.
6753 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6755 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6756 Default value is now t. Doc fix.
6758 * indent.c (Fvertical_motion): Compute and apply the overshoot
6759 logic when moving up, not only when moving down. Fix the
6760 confusing name and values of the it_overshoot_expected variable;
6761 logic changes accordingly. (Bug#9254) (Bug#9549)
6763 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6764 CHARPOS is covered by a display string which includes newlines.
6765 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6766 is covered by a display string with embedded newlines.
6768 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6770 * dbusbind.c (Fdbus_register_signal): Add match rule to
6771 Vdbus_registered_objects_table. (Bug#9581)
6772 (Fdbus_register_method, Vdbus_registered_objects_table):
6773 Fix docstring.
6775 2011-09-24 Jim Meyering <meyering@redhat.com>
6777 do not ignore write error for any output size
6778 The previous change was incomplete.
6779 While it makes emacs --batch detect the vast majority of stdout
6780 write failures, errors were still ignored whenever the output size is
6781 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6782 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6783 && echo FAIL: ignored write error
6784 FAIL: ignored write error
6785 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6786 && echo FAIL: ignored write error
6787 FAIL: ignored write error
6788 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6790 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6792 * emacs.c (Fkill_emacs): In noninteractive mode exit
6793 non-successfully if a write error occurred on stdout. (Bug#9574)
6795 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6797 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6798 the xassert test.
6800 * dispextern.h (struct it): Update the comment documenting what
6801 can it->OBJECT be.
6803 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6805 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6806 a display string, extend search for cursor position to end of row.
6807 (find_row_edges): If the row ends in a newline from a display
6808 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6809 Handle the case of a display string with multiple newlines.
6810 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6811 non-empty line. Fixes confusing cursor motion with arrow keys at
6812 the beginning of a line that starts with whitespace.
6814 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6816 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6817 (bug#9493).
6819 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6821 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6822 boolean (Bug#9154).
6824 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6826 * xdisp.c (display_line): Record maximum and minimum buffer
6827 positions even if no glyphs were produced (e.g., by a zero-width
6828 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6829 buffer positions that will be removed from the glyph row because
6830 they don't fit.
6831 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6832 column is beyond frame width: don't subtract 1 "pixel" when
6833 computing width of the stretch.
6834 (reseat_at_next_visible_line_start): Undo the change made on
6835 2011-09-17 that saved paragraph information and restored it after
6836 the call to `reseat'. (Bug#9545)
6838 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6840 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6841 and turn window cursor on if cleared (Bug#9415).
6843 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6845 * search.c (boyer_moore): Take unibyte characters from pattern
6846 literally. (Bug#9458)
6848 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6850 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6852 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6854 Fix minor problem found by static checking.
6855 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6856 initialized, to pacify gcc -Wuninitialized.
6858 * fileio.c: Report proper errno when syscall falls.
6859 (Finsert_file_contents): Save and restore errno,
6860 so that report_file_error outputs the correct diagnostic.
6861 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6863 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6865 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6867 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6869 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6870 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6872 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6874 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6875 about the current paragraph and restore it after the call to reseat.
6877 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6878 (bidi_find_paragraph_start): Search back for paragraph beginning
6879 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6880 (bidi_move_to_visually_next): Only trigger paragraph-related
6881 computations when the last character is a newline or at EOB, not
6882 just any NEUTRAL_B. (Bug#9470)
6884 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6885 truncated lines if point is covered by a display string. (Bug#9524)
6887 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6889 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6890 (cons_to_x_long): New function.
6891 (lisp_data_to_selection_data): Use it. Correct the test for
6892 short-versus-long data; it was negated. Break out of vector
6893 loop, for efficiency, when a long datum is discovered.
6895 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6897 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6899 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6901 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6902 GCC PR/17406) by declaring this function with external scope.
6904 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6906 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6907 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6909 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6911 * editfns.c (Fformat): Correctly handle text properties on "%%".
6913 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6915 * xterm.c (x_draw_composite_glyph_string_foreground):
6916 * w32term.c (x_draw_composite_glyph_string_foreground):
6917 * term.c (encode_terminal_code):
6918 * composite.c (composition_update_it, get_composition_id):
6919 * xdisp.c (get_next_display_element)
6920 (fill_composite_glyph_string): Add comments about special meaning
6921 of TAB characters in a composition.
6923 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6925 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6926 This occurs when processing a multibyte format.
6927 Problem reported by Wolfgang Jenker.
6929 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6931 * xdisp.c (try_cursor_movement): Only check for exact match if
6932 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6934 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6936 Remove unused external symbols.
6937 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6938 * xdisp.c (calc_pixel_width_or_height): Now static.
6939 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6940 * indent.c (check_display_width):
6941 * w32term.c: Fix comment to match code.
6942 * xterm.c, xterm.h (x_catching_errors): Remove.
6944 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6946 * xselect.c: Use signed conversions more consistently (Bug#9498).
6947 (selection_data_to_lisp_data): Assume incoming selection data are
6948 signed integers, not unsigned. This is to be consistent with
6949 outgoing selection data, which was modified to use signed integers
6950 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6951 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6952 expects long, not unsigned long.
6954 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6956 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6957 computation of loop end. Reported by Johan Bockgård
6958 <bojohan@gnu.org>.
6960 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6962 * frame.c (Fother_visible_frames_p): Function deleted.
6964 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6966 * indent.c (compute_motion): Process display vector front to back
6967 rather than the other way around. (Bug#2496)
6969 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6971 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6973 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6975 * minibuf.c (Fread_from_minibuffer): Doc fix.
6977 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6979 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6980 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6982 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6984 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6985 value for non-existent files.
6987 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6989 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6990 set its "size" to -1. This will set the modtime_size field of
6991 the corresponding buffer to -1, which is what
6992 verify-visited-file-modtime expects for files that do not exist.
6993 (Bug#9139)
6995 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6997 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6998 here ...
6999 * lisp.h: ... from here. push_key_description is no longer
7000 defined in keyboard.c, so its declaration should not be in
7001 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7002 logically belongs with push_key_description.
7004 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7006 * buffer.h: Include <sys/types.h> instead of <time.h>.
7007 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7008 Problem reported by Herbert J. Skuhra.
7010 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7012 * xml.c (parse_region): Make the parsing work for
7013 non-comment-starting XML files again (bug#9144).
7015 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7017 * image.c (gif_load): Fix calculation of bottom and right corner.
7018 (Bug#9468)
7020 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7022 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7023 redisplay in small windows.
7025 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7027 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7029 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7031 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7032 Operate on live windows only.
7034 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7036 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7038 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7040 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7041 only under bidi iteration.
7043 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7045 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7047 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7049 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7050 Without this fix, the command to link temacs failed due to an
7051 undefined symbol __builtin_isnan. This is because
7052 /usr/include/iso/math_c99.h #defines isnan(x) to
7053 __builtin_isnan(x), but the bundled gcc, which identifies itself
7054 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7055 a __builtin_isnan.
7056 * floatfns.c (isnan): #undef, and then #define to a clone of
7057 what's in data.c.
7058 (Fisnan): Always define, since it's always available now.
7059 (syms_of_floatfns): Always define isnan at the Lisp level.
7061 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7063 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7065 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7067 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7068 The previous code assumed that file offsets (off_t values) fit in
7069 EMACS_INT variables, which is not true on typical 32-bit hosts.
7070 The code messed up by falsely reporting buffer overflow in cases
7071 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7072 when "big" contains more than 2**29 bytes, even though this
7073 inserts just one byte and does not overflow the buffer.
7074 (Finsert_file_contents): Store file offsets as off_t
7075 values, not as EMACS_INT values. Check for overflow when
7076 converting between EMACS_INT and off_t. When checking for
7077 buffer overflow or for overlap, take the offsets into account.
7078 Don't use EMACS_INT for small values where int suffices.
7079 When checking for overlap, fix a typo: ZV was used where
7080 ZV_BYTE was intended.
7081 (Fwrite_region): Don't assume off_t fits into 'long'.
7082 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7084 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7086 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7088 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7090 sprintf-related integer and memory overflow issues (Bug#9412).
7092 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7093 (esprintf, exprintf, evxprintf): New functions.
7094 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7095 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7096 (modify_event_symbol): Do not assume that the length of
7097 name_alist_or_stem is safe to alloca and fits in int.
7098 (Fexecute_extended_command): Likewise for function name and binding.
7099 (Frecursion_depth): Wrap around reliably on integer overflow.
7100 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7101 since some callers pass EMACS_INT values.
7102 (Fsingle_key_description): Don't crash if symbol name contains more
7103 than MAX_ALLOCA bytes.
7104 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7105 (get_minibuffer): Arg is now EMACS_INT, not int.
7106 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7107 (esprintf, exprintf, evxprintf): New decls.
7108 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7110 * dbusbind.c (signature_cat): New function.
7111 (xd_signature, Fdbus_register_signal):
7112 Do not overrun buffer; instead, report string overflow.
7114 * dispnew.c (add_window_display_history): Don't overrun buffer.
7115 Truncate instead; this is OK since it's just a log.
7117 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7118 even if the time zone offset is outlandishly large.
7119 Don't mishandle offset == INT_MIN.
7121 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7122 when creating daemon; the previous buffer-overflow check was incorrect.
7124 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7125 which has the guts of the old verror function.
7127 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7128 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7130 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7131 (font_unparse_xlfd): Don't blindly alloca long strings.
7132 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7133 fits in int, when using sprintf. Use single snprintf to count
7134 length of string rather than counting it via multiple sprintfs;
7135 that's simpler and more reliable.
7136 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7137 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7138 sprintf, in case result does not fit in int.
7140 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7141 (fontset_from_font): Print it.
7143 * frame.c (tty_frame_count): Now printmax_t, not int.
7144 (make_terminal_frame, set_term_frame_name): Print it.
7145 (x_report_frame_params): In X, window IDs are unsigned long,
7146 not signed long, so print them as unsigned.
7147 (validate_x_resource_name): Check for implausibly long names,
7148 and don't assume name length fits in 'int'.
7149 (x_get_resource_string): Don't blindly alloca invocation name;
7150 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7151 not fit in int.
7153 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7154 (xg_check_special_colors, xg_set_geometry):
7155 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7157 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7158 Use esprintf, not sprintf, in case result does not fit in int.
7160 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7161 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7162 it as a large positive number.
7163 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7164 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7166 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7167 in case result does not fit in int.
7169 * print.c (float_to_string): Detect width overflow more reliably.
7170 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7171 buffer overrun. Don't assume list length fits in 'int'. Treat
7172 print length of 0 as 0, not as infinity; to be consistent with other
7173 uses of print length in this function. Don't overflow print length
7174 index. Don't assume hash table size fits in 'long', or that
7175 vectorlike size fits in 'unsigned long'.
7177 * process.c (make_process): Use printmax_t, not int, to format
7178 process-name gensyms.
7180 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7182 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7183 to avoid potential buffer overrun.
7185 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7186 if X resource line is longer than 512 bytes.
7188 * xfns.c (x_window): Make sprintf buffer a bit bigger
7189 to avoid potential buffer overrun.
7191 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7193 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7195 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7197 Integer overflow fixes for scrolling, etc.
7198 Without these, Emacs silently mishandles large integers sometimes.
7199 For example, "C-u 4294967297 M-x recenter" was treated as if
7200 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7202 * xdisp.c (try_window_id): Check Emacs fixnum range before
7203 converting to 'int'.
7205 * window.c (window_scroll_line_based, Frecenter):
7206 Check that an Emacs fixnum is in range before assigning it to 'int'.
7207 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7208 values converted from Emacs fixnums.
7209 (Frecenter): Don't wrap around a line count if it is out of 'int'
7210 range; instead, treat it as an extreme value.
7211 (Fset_window_configuration, compare_window_configurations):
7212 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7214 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7215 that can exceed INT_MAX. Check that EMACS_INT value is in range
7216 before assigning it to the (possibly-narrower) index.
7217 (match_limit): Don't assume that a fixnum can fit in 'int'.
7219 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7220 exceed INT_MAX.
7222 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7223 (Fvertical_motion): Don't wrap around LINES values that don't fit
7224 in 'int'. Instead, treat them as extreme values. This is good
7225 enough for windows, which can't have more than INT_MAX lines anyway.
7227 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7229 * Require libxml/parser.h to avoid compilation warning.
7231 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7233 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7234 since this reportedly can destroy thread storage.
7236 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7238 * syntax.c (find_defun_start): Update all cache variables if
7239 exiting early (Bug#9401).
7241 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7243 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7245 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7246 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7247 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7249 * term.c (tty_append_glyph): New function.
7250 (produce_stretch_glyph): Static function and its prototype deleted.
7252 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7253 Add prototypes.
7255 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7257 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7258 when checking :margin (Bug#9390).
7259 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7260 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7261 so that the name doesn't mislead. All uses changed.
7263 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7265 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7266 set_tty_hooks.
7268 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7270 * xdisp.c (move_it_to): Don't bail out early when reaching
7271 position beyond to_charpos, if we are scanning backwards.
7272 (move_it_vertically_backward): When DY == 0, make sure we get to
7273 the first character in the line after the newline.
7275 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7277 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7278 (ccl_driver): Do not generate an out-of-range pointer.
7279 (Fccl_execute_on_string): Remove unnecessary check for
7280 integer overflow, noted by Stefan Monnier in
7281 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7282 Remove a FIXME that didn't need fixing.
7283 Simplify the newly-introduced buffer reallocation code.
7285 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7287 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7289 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7291 Integer and memory overflow issues (Bug#9196).
7293 * doc.c (get_doc_string): Rework so that
7294 get_doc_string_buffer_size is the actual buffer size, rather than
7295 being 1 less than the actual buffer size; this makes xpalloc more
7296 convenient.
7298 * image.c (x_allocate_bitmap_record, cache_image):
7299 * xselect.c (Fx_register_dnd_atom):
7300 Simplify previous changes by using xpalloc.
7302 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7303 since either will do and ptrdiff_t is convenient with xpalloc.
7305 * charset.c (charset_table_size)
7306 (struct charset_sort_data.priority): Now ptrdiff_t.
7307 (charset_compare): Don't overflow if priorities differ greatly.
7308 (Fsort_charsets): Don't assume list length fits in int.
7309 Check for size-calculation overflow when allocating sort data.
7310 (syms_of_charset): Allocate an initial charset table that is
7311 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7313 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7315 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7316 The actual value is always <= INT_MAX, and leaving it unsigned made
7317 overflow checking harder.
7319 * dispextern.h (struct glyph_matrix.rows_allocated)
7320 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7321 with xpalloc. The values are still always <= INT_MAX.
7323 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7325 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7326 (SAFE_NALLOCA): New macro.
7328 * region-cache.c (struct boundary.pos, find_cache_boundary)
7329 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7330 (set_cache_region, invalidate_region_cache)
7331 (revalidate_region_cache, know_region_cache, region_cache_forward)
7332 (region_cache_backward, pp_cache):
7333 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7334 so that ptrdiff_t * can be passed to xpalloc.
7335 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7336 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7337 (pp_cache): Don't assume cache_len fits in int.
7338 * region-cache.h: Adjust extern decls to match.
7340 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7341 EMACS_INT, since either will do, for xpalloc.
7343 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7344 (xnmalloc, xnrealloc, xpalloc): New functions.
7346 * bidi.c (bidi_shelve_header_size): New constant.
7347 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7348 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7350 * bidi.c (bidi_cache_shrink):
7351 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7352 (overlay_strings):
7353 Don't update size of array until after memory allocation succeeds,
7354 because xmalloc/xrealloc may not return.
7355 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7356 now that we have proper integer overflow checking.
7357 (record_overlay_string, overlay_strings): Catch overflows when
7358 calculating size of overlay_str_buf.
7360 * callproc.c (Fcall_process): Check for size overflow when
7361 calculating size of args2.
7362 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7363 Normally we prefer signed values, but sticking with ptrdiff_t would
7364 require adding more-complicated checks.
7366 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7367 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7368 Redo buffer-overflow calculations to avoid integer overflow.
7369 Add a FIXME comment where memory seems to be over-allocated.
7371 * character.c (Fstring): Check for size-calculation overflow.
7373 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7374 unnecessary integer overflow. Check for size overflow.
7375 (encode_coding_object): Don't update size until xmalloc succeeds.
7377 * composite.c (get_composition_id): Check for overflow in glyph
7378 length calculations.
7380 Integer and memory overflow fixes for display code.
7381 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7382 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7383 (scrolling_window): Check for overflow in size calculations.
7384 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7385 Don't assume glyph table len fits in int.

7387 (row_table_size): Now ptrdiff_t, not int.
7388 (scrolling_window): Avoid overflow in size calculations.
7389 Don't update size until allocation succeeds.

7396 (get_doc_string): Check for size calculation overflow.
7397 Don't update size until allocation succeeds.
7398 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7399 EMACS_INT, where ptrdiff_t will do.
7400 (Fsubstitute_command_keys): Check for string overflow.
7402 * editfns.c (set_time_zone_rule): Don't assume environment length
7403 fits in int.
7404 (message_length): Now ptrdiff_t, not int.
7405 (Fmessage_box): Don't update size until allocation succeeds.
7406 Don't assume message length fits in int.
7407 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7409 * emacs.c (main): Do not reallocate argv, since there is a null at
7410 the end that can be overwritten, and this way there's no need to
7411 worry about size-calculation overflow.
7412 (sort_args): Check for size-calculation overflow.
7414 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7415 alloc succeeds.
7416 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7418 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7419 (x_set_scroll_bar_width, x_figure_window_size):
7420 Check for integer overflow.
7421 (x_set_alpha): Do not assume XINT fits in int.
7423 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7424 This is for the members text_lines, text_cols, total_lines, total_cols,
7425 where the system imposes an 'int' limit.
7427 * fringe.c (Fdefine_fringe_bitmap):
7428 Don't update size until alloc works.
7430 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7431 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7433 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7434 Check for size-calculation overflow.
7435 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7436 do, as we prefer signed integers.
7437 (id_to_widget.max_size, id_to_widget.used)
7438 (xg_store_widget_in_map, xg_remove_widget_from_map)
7439 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7440 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7441 Use and return ptrdiff_t, not int.
7442 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7443 * gtkutil.h: Change prototypes to match the above.
7445 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7446 are duplicate now that they've been promoted to lisp.h.
7447 (x_allocate_bitmap_record, x_alloc_image_color)
7448 (make_image_cache, cache_image, xpm_load):
7449 Don't update size until alloc is done.
7450 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7451 (x_detect_edges):
7452 Check for size calculation overflow.
7453 (ct_colors_allocated_max): New constant.

7458 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
7459 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7460 Use ptrdiff_t, not int, to count maps.
7461 (read_char_minibuf_menu_prompt): Check for overflow in size
7462 calculations. Don't update size until allocation succeeds.
7463 Redo calculations to avoid overflow.
7464 * keyboard.h: Change prototypes to match the above.

7469 * keymap.h: Change prototypes to match the above.
7471 * lread.c (read1, init_obarray): Don't update size until alloc done.
7473 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
7474 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

7489 * search.c (Freplace_match): Check for size calculation overflow.
7490 (Fset_match_data): Don't assume list lengths fit in 'int'.
7492 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7493 for command line length. Do not attempt to address one before the
7494 beginning of an array, as that's not portable.
7496 * term.c (max_frame_lines): Remove; unused.
7497 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7498 not int.

7506 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
7507 subtracting pointers.

7521 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
7522 Use ptrdiff_t, not int, for sizes.
7523 (Finternal_make_lisp_face, cache_face):
7524 Check for size calculation overflow.
7525 (cache_face): Treat size calculation overflows as if they were
7526 memory exhaustion (the usual treatment), rather than aborting.
7528 * xfns.c (x_encode_text, x_set_name_internal)
7529 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7530 sizes, since they can exceed INT_MAX in size. Check for size

7534 (xg_select): Check for size calculation overflow.
7535 Don't update size until alloc done.
7537 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7538 as sprintf is limited to int lengths.
7540 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7541 (X_LONG_MIN): New macros.
7542 Use them to make the following changes clearer.
7543 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7544 This change doesn't affect the value now, but it may help remind
7545 future maintainers not to raise the value too much later.
7546 (SELECTION_QUANTUM): Remove, replacing with ...
7547 (selection_quantum): ... new function, which avoids overflow.
7548 All uses changed.
7549 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7550 assumption that selection length fits in 'int'.
7551 (x_reply_selection_request, x_handle_selection_request)
7552 (x_get_window_property, receive_incremental_selection)
7553 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7554 (lisp_data_to_selection_data, clean_local_selection_data):
7555 Use ptrdiff_t, not int, to record length of selection.
7556 (x_reply_selection_request, x_get_window_property)
7557 (receive_incremental_selection, x_property_data_to_lisp):
7558 Redo calculations to avoid overflow.
7559 (x_reply_selection_request): When sending hint, ceiling it at
7560 X_LONG_MAX rather than relying on wraparound overflow to send
7561 something.
7562 (x_get_window_property, receive_incremental_selection)
7563 (lisp_data_to_selection_data, x_property_data_to_lisp):
7564 Check for size-calculation overflow.
7565 (x_get_window_property, receive_incremental_selection)
7566 (lisp_data_to_selection_data, Fx_register_dnd_atom):
7567 Don't store size until memory allocation succeeds.
7568 (x_get_window_property): Plug memory leak on memory exhaustion.
7569 Don't double-block input; malloc is safe here. Don't assume 2**34
7570 - 4 fits in unsigned long. Add an xassert to check
7571 XGetWindowProperty overflow. Be more careful about overflow
7572 calculations, and distinguish size from memory overflow better.
7573 (receive_incremental_selection): When tracing, don't assume
7574 unsigned int is less than INT_MAX.
7575 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7576 harmful) conversions of unsigned short to int.
7577 (lisp_data_to_selection_data): Don't assume that integers
7578 in the range -65535 through -1 fit in an X unsigned short.
7579 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7580 result parameters unless successful. Rely on cons_to_unsigned
7581 to report problems with elements; the old code wasn't right anyway.
7582 (x_check_property_data): Check for int overflow; we cannot use
7583 a wider type due to X limits.
7584 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7586 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7588 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7589 (x_term_init): Check for size calculation overflow.
7590 (x_color_cells): Don't store size until memory allocation succeeds.
7591 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
7592 Don't assume alloca size is less than MAX_ALLOCA.
7593 (x_term_init): Don't assume length fits in int (sprintf is limited
7594 to int size).
7596 Use ptrdiff_t for composition IDs.
7597 * character.c (lisp_string_width):
7598 * composite.c (composition_table_size, n_compositions)
7599 (get_composition_id, composition_gstring_from_id):
7600 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
7601 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
7602 * window.c (Frecenter):
7603 Use ptrdiff_t, not int, for composition IDs.
7604 * composite.c (get_composition_id): Check for integer overflow.
7605 * composite.h: Adjust prototypes to match the above changes.
7607 Use ptrdiff_t for hash table indexes.

7614 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
7615 * image.c (xpm_get_color_table_h):
7616 * lisp.h (hash_lookup, hash_put):
7617 * minibuf.c (Ftest_completion):
7618 Use ptrdiff_t for hash table indexes, not int (which is too
7619 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7620 32-bit --with-wide-int hosts).
7622 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7623 Add a FIXME comment about memory leaks.
7624 (syms_of_charset): Don't assume xmalloc returns.
7626 Don't assume that stated character widths fit in int.
7627 * character.c (Fchar_width, c_string_width, lisp_string_width):
7628 * character.h (CHAR_WIDTH):
7629 * indent.c (MULTIBYTE_BYTES_WIDTH):
7630 Use sanitize_char_width to avoid undefined and/or bad behavior
7631 with outlandish widths.
7632 * character.h (sanitize_tab_width): Rename from sanitize_width,
7633 now that we have two such functions. All uses changed.
7634 (sanitize_char_width): New inline function.
7636 Don't assume that tab-width fits in int.
7637 * character.h (sanitize_width): New inline function.
7638 (SANE_TAB_WIDTH): New macro.
7639 (ASCII_CHAR_WIDTH): Use it.
7640 * indent.c (sane_tab_width): Remove. All uses replaced by
7641 SANE_TAB_WIDTH (current_buffer).
7642 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
7644 * fileio.c: Integer overflow issues with file modes.
7645 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7647 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
7648 Remove unreachable code.
7649 (read_hex, load_charset_map_from_file): Check for integer overflow.
7651 * xterm.c: Don't go over XClientMessageEvent limit.
7652 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7653 (x_send_scroll_bar_event): Likewise. Check that the size does not
7654 exceed limits imposed by XClientMessageEvent, as well as the usual
7655 ptrdiff_t and size_t limits.
7657 * keyboard.c: Overflow, signedness and related fixes.
7658 (make_lispy_movement): Use same integer type in forward decl
7659 that is used in the definition.
7660 (read_key_sequence, keyremap_step):
7661 Change bufsize argument back to int, undoing my 2011-03-30 change.
7662 We prefer signed types, and int is wide enough here.
7663 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7664 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7665 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7666 length, not size_t. Use ptrdiff_t for index, not int.
7667 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7668 possibility of integer overflow.
7670 Overflow, signedness and related fixes for images.
7672 * dispextern.h (struct it.stack[0].u.image.image_id)
7673 (struct_it.image_id, struct image.id, struct image_cache.size)
7674 (struct image_cache.used, struct image_cache.ref_count):

7679 * nsmenu.m (update_frame_tool_bar):
7680 * xdisp.c (calc_pixel_width_or_height):
7681 * xfns.c (image_cache_refcount):
7682 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7683 on typical 64-bit hosts.
7685 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7686 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7687 Omit unnecessary casts to int.

7691 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7692 (lookup_image): Remove unnecessary tests.
7693 (xbm_image_p): Locals are now of int, not EMACS_INT,
7694 since parse_image_check makes sure they fit into int.
7695 (png_load, gif_load, svg_load_image):
7696 Prefer int to unsigned where either will do.
7697 (tiff_handler): New function, combining the cores of the
7698 old tiff_error_handler and tiff_warning_handler.
7699 This function is rewritten to use vsnprintf and thereby avoid
7700 stack buffer overflows. It uses only the features of vsnprintf
7701 that are common to both POSIX and native Microsoft.
7702 (tiff_error_handler, tiff_warning_handler): Use it.
7703 (tiff_load, gif_load, imagemagick_load_image):
7704 Don't assume :index value fits in 'int'.
7705 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7706 (imagemagick_load_image): Check that crop parameters fit into
7707 the integer types that MagickCropImage accepts. Don't assume
7708 Vimagemagick_render_type has a nonnegative value. Don't assume
7709 size_t fits in 'long'.
7710 (gs_load): Use printmax_t to print the widest integers possible.
7711 Check for integer overflow when computing image height and width.
7713 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7715 * xdisp.c (redisplay_window): Don't force window start if point
7716 will be invisible in the resulting window. (Bug#9324)
7718 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7720 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7721 the display spec is of the form `(space ...)'.
7722 (handle_display_spec): Return the value returned by
7723 handle_single_display_spec, not just 1 or zero.
7724 (handle_single_display_spec): If the display spec is of the form
7725 `(space ...)', and specifies display in the text area, return 2
7726 rather than 1.
7727 (try_cursor_movement): Check for the need to scroll more
7728 accurately, and prefer exact match for point under bidi.
7729 Don't advance `row' beyond the last row of the window.
7731 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7732 into disp_prop; all users changed.
7734 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7735 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7736 for the text covered by the display property.
7738 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7740 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7746 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7747 buffers, return left-to-right.
7748 (set_cursor_from_row): Consider candidate row a win if its glyph
7749 represents a newline and point is on that newline. Fixes cursor
7750 positioning on the newline at EOL of R2L text within L2R
7751 paragraph, and vice versa.
7752 (try_cursor_movement): Check continued rows, in addition to
7753 continuation rows. Fixes unwarranted scroll when point enters a
7754 continued line of R2L text within an L2R paragraph, or vice versa.
7755 (cursor_row_p): Consider the case of point being equal to
7756 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7757 from the end of a short line to the beginning of a continued line
7758 of R2L text within L2R paragraph.
7759 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7760 composed characters.

7769 a character.
7771 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7773 * nsfont.m (ns_otf_to_script): Fix typo.
7775 2011-08-22 Kenichi Handa <handa@m17n.org>
7777 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7778 extra slot even if the purpose is char-code-property-table.
7780 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7782 * xdisp.c (redisplay_window): When computing centering_position,
7783 account for the height of the header line. (Bug#8874)
7785 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7786 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7787 candidate is selected by the mouse, and that candidate has a
7788 composed character under the mouse.
7790 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7791 coordinates reported by pos-visible-in-window-p for a composed
7792 character in column zero.
7794 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
7796 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7798 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7800 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7801 consider it a hit if to_charpos is anywhere in the range of the
7802 composed buffer positions.
7804 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7806 * image.c (gif_load): Don't assume that each subimage has the same
7807 dimensions as the base image. Handle disposal method that is
7808 "undefined" by the gif spec (Bug#9335).
7810 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7812 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7813 (Fcondition_case): Document `debug' symbol in error handler.
7815 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7817 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7818 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7819 from an Org mode buffer to a Speedbar frame.
7821 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7822 a composition, take its buffer position from IT->cmp_it.charpos.
7823 Fixes cursor positioning at the beginning of a line that begins
7824 with a composed character.
7826 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7828 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7829 character bidirectional type, use STRONG_L instead. Fixes crashes
7830 in a buffer produced by `describe-categories'.
7832 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7833 members before the level stack, so they would be saved and
7834 restored when copying iterator state. Fixes incorrect reordering
7835 around TABs covered by display properties.
7837 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7839 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7844 (internal_condition_case_2, internal_condition_case_n):
7845 Remove unnecessary aborts (Bug#9081).
7847 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7849 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7850 has no `load' handler, try opening the file locally. (Bug#9311)
7852 2011-08-16 Ken Brown <kbrown@cornell.edu>
7854 * gmalloc.c: Expand comment.
7856 2011-08-16 Eli Zaretskii <eliz@gnu.org>
7858 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
7859 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
7861 2011-08-16 Ken Brown <kbrown@cornell.edu>
7863 Fix memory allocation problems in Cygwin build (Bug#9273).
7865 * unexcw.c ( __malloc_initialized): Declare external variable.

7871 dumped emacs.
7872 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
7873 in the static heap.
7874 [CYGWIN] (special_realloc): New function.
7875 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
7876 requests to realloc storage in the static heap.

7887 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
7889 * dispextern.h: Fix a typo in the comment to bidi_type_t.
7891 * chartab.c: Improve commentary for the uniprop_table API.
7893 * bidi.c (bidi_paragraph_init): Support zero value of
7894 bidi_ignore_explicit_marks_for_paragraph_level.

7896 biditype.h and bidimirror.h.
7898 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
7899 coordinates of the iterator when restoring from ppos_it.
7900 (Bug#9296)
7902 2011-08-14 Kenichi Handa <handa@m17n.org>
7904 * process.c (create_process): Call setup_process_coding_systems
7905 after the pid of the process is set to -1 (Bug#8162).
7907 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7909 * xdisp.c (move_it_in_display_line_to): Don't invoke
7910 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7911 ppos_it. Fixes vertical cursor motion when line beginning is
7912 covered by an image. (Bug#9296)
7914 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7916 * nsterm.h (ns_run_ascript): Declare.
7917 (NSAPP_DATA2_RUNASSCRIPT): Define.
7919 * nsfns.m (as_script, as_result, as_status): New static variables.
7920 (ns_run_ascript): New function.
7921 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7922 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7923 the event loop. Get status from as_status (Bug#7276).
7925 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7926 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7927 the event loop (Bug#7276).
7929 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7931 * gnutls.c (QCgnutls_bootprop_priority)
7932 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7933 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7934 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
7935 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
7936 (QCgnutls_bootprop_verify_hostname_error)
7937 (QCgnutls_bootprop_callbacks_verify): Rename from
7938 Qgnutls_bootprop_..., all uses changed.
7940 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
7941 uses changed.
7943 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
7945 * xfaces.c (Qframe_set_background_mode): Now static.
7946 * dispextern.h (Qframe_set_background_mode): Remove decl.

7950 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7952 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7953 (Fnetwork_interface_list): Allocate in increments of bytes instead
7954 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7955 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7956 sockaddr.
7957 (struct ifflag_def): notrailers is smart on OSX.
7958 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7959 Get hardware address with getifaddrs if available.
7961 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7963 * xdisp.c (iterate_out_of_display_property): xassert that
7964 IT->position is set to within IT->object's boundaries. Break from
7965 the loop as soon as EOB is reached; avoids infloops in redisplay
7966 when IT->position is set up wrongly due to some bug.
7967 Set IT->current to match the bidi iterator unconditionally.
7968 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7969 entry. Force push_it to save on the stack the current
7970 buffer/string position, to be restored by pop_it. Fix flags in
7971 the iterator structure wrt the object coming from a display
7972 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7973 properties. (Bug#9284)
7975 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7977 * fontset.c (fontset_get_font_group): Add proper type checks.

7982 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
7983 and LC_VERSION_MIN_MACOSX.
7984 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
7985 (dump_it) [LC_FUNCTION_STARTS]: Use it.
7987 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7989 * xdisp.c (forward_to_next_line_start): Allow to use the
7990 no-display-properties-and-no-overlays under bidi display.
7991 Set disp_pos in the bidi iterator to avoid searches for display
7992 properties and overlays.
7994 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7996 * editfns.c (Fset_time_zone_rule): Document relationship with the
7997 setenv function.
7999 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8000 the font entity extracted from the cache (Bug#8109).
8002 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8004 * composite.c (autocmp_chars): Don't reset point. That is done by
8005 restore_point_unwind (Bug#5984).
8007 2011-08-07 Juri Linkov <juri@jurta.org>
8009 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8010 to show the arg `TIME' instead of `TIMEVAL'.
8012 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8014 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8015 display property strides EOL and includes a newline, as in
8016 longlines-mode. (Bug#9254)
8017 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8018 word-wrap under bidirectional display. (Bug#9224)
8020 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8021 is non-zero, even if the data buffer is NULL. Fixes a crash in
8022 vertical-motion with longlines-mode. (Bug#9254)
8024 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8026 * bidi.c <bidi_cache_total_alloc>: Now static.
8027 (bidi_initialize): Initialize bidi_cache_total_alloc.
8029 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8030 cache. (Bug#9221)
8032 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8033 amount allocated this far in `bidi_cache_total_alloc'.
8034 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8035 non-zero, only free the data buffer without restoring the cache
8036 contents. All callers changed.
8038 * dispextern.h (bidi_unshelve_cache): Update prototype.
8040 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8041 (move_it_in_display_line, move_it_to)
8042 (move_it_vertically_backward, move_it_by_lines): Replace the call
8043 to xfree to an equivalent call to bidi_unshelve_cache.
8044 (move_it_in_display_line_to): Fix logic of returning
8045 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8047 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8049 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8050 came from a string character with a `cursor' property. (Bug#9229)
8052 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8054 * Makefile.in (LIB_PTHREAD): New variable.
8055 (LIBES): Add LIB_PTHREAD (Bug#9216).
8057 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8058 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8060 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8062 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8064 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8066 * xterm.c (x_find_topmost_parent): New function.
8067 (x_set_frame_alpha): Find topmost parent window with
8068 x_find_topmost_parent and set the property there also (bug#9181).
8069 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8071 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8073 * callproc.c (Fcall_process): Avoid vfork clobbering
8074 the local vars buffer, coding_systems, current_dir.
8076 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8078 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8080 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8082 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8083 so that it is not optimized away.
8085 * xdisp.c (compute_display_string_pos): Remove unused local.
8087 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8089 Fix slow cursor motion and scrolling in large buffers with
8090 selective display, like Org Mode buffers. (Bug#9218)
8092 * dispextern.h (struct bidi_it): New member disp_prop_p.
8094 * xdisp.c: Remove one-slot cache of display string positions.
8095 (compute_display_string_pos): Accept an additional argument
8096 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8097 for a display string or property. If found, set DISP_PROP_P
8098 non-zero.
8100 * bidi.c (bidi_fetch_char): Accept an additional argument
8101 DISP_PROP_P, and pass it to compute_display_string_pos.
8102 Only handle text covered by a display string if DISP_PROP_P is returned
8103 non-zero. All callers of bidi_fetch_char changed.
8105 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8107 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8109 2010-12-03 Don March <don@ohspite.net>
8111 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8112 last character M-[char] is translated to ESC [char] (bug#7541).
8114 2011-08-02 Kenichi Handa <handa@m17n.org>
8116 * lisp.h (uniprop_table): Extern it.
8118 * chartab.c (uniprop_table): Make it non-static.
8120 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8122 * xdisp.c (forward_to_next_line_start): Accept additional argument
8123 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8124 on the newline.
8125 (reseat_at_next_visible_line_start): Use the bidi iterator state
8126 returned by forward_to_next_line_start to restore the state of
8127 it->bidi_it after backing up to previous newline. (Bug#9212)
8129 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8131 * regex.c (re_comp): Protoize.
8132 (re_exec): Fix return type.
8133 (regexec): Fix type of `ret'. (Bug#9203)
8135 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8137 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8138 This is needed if max-image-size is a floating-point number.
8140 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8142 * print.c (print_object): Print empty symbol as ##.
8144 * lread.c (read1): Read ## as empty symbol.
8146 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8148 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8149 setting frame foreground color (Bug#9175).
8150 (x_set_background_color): Likewise.
8152 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8153 contents (Bug#9176).
8154 (EmacsTooltip -init): Remove bezels and add shadows to
8155 tooltip windows.
8157 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8158 or scroll bar (Bug#8470).
8160 * nsfont.m (nsfont_open): Remove assignment to voffset and
8161 unnecessary vars hshink, expand, hd, full_height, min_height.
8162 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8164 * nsterm.h (nsfont_info): Remove voffset field.
8166 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8168 Implement strike-through and overline on NextStep (Bug#8863).
8170 * nsfont.m (nsfont_open): Use underline position provided by font,
8171 instead of hard-coded value of 2.
8172 (nsfont_draw): Call ns_draw_text_decoration instead.
8174 * nsterm.h: Add declaration for ns_draw_text_decoration.
8176 * nsterm.m (ns_draw_text_decoration): New function for drawing
8177 underline, overline, and strike-through.
8178 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8179 ns_draw_text_decoration. Change treatment of cursor drawing to
8180 accommodate underlining, etc.
8182 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8184 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8185 default.
8187 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8189 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8190 Without this fix, if a signal arrives just after memory fills up,
8191 'malloc' might be invoked reentrantly.
8193 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8194 In other words, assume that every image size is allowed, on non-X
8195 hosts. This assumption is probably wrong, but it lets Emacs compile.
8197 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8199 * regex.c (re_iswctype): Convert return values to boolean.
8201 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8203 * xdisp.c (compute_display_string_pos): Don't use cached display
8204 string position if the buffer had its restriction changed.
8205 (Bug#9184)
8207 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8209 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8211 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8213 Integer signedness and overflow and related fixes. (Bug#9079)
8215 * bidi.c: Integer size and overflow fixes.
8216 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8217 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8218 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8219 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8220 (bidi_find_other_level_edge):
8221 Use ptrdiff_t instead of EMACS_INT where either will do.
8222 This works better on 32-bit hosts configured --with-wide-int.
8223 (bidi_cache_ensure_space): Check for size-calculation overflow.
8224 Use % rather than repeated addition, for better worst-case speed.
8225 Don't set bidi_cache_size until after xrealloc returns, because it
8226 might not return.
8227 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8228 (bidi_cache_ensure_space): Also check that the bidi cache size
8229 does not exceed that of the largest Lisp string or buffer. See Eli
8230 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8232 * alloc.c (__malloc_size_t): Remove.
8233 All uses replaced by size_t. See Andreas Schwab's note
8234 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8236 * image.c: Improve checking for integer overflow.
8237 (check_image_size): Assume that f is nonnull, since
8238 it is always nonnull in practice. This is one less thing to
8239 worry about when checking for integer overflow later.
8240 (x_check_image_size): New function, which checks for integer
8241 overflow issues inside X.
8242 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8243 This removes the need for a memory_full check.
8244 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8245 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8246 (xbm_read_bitmap_data): Change locals back to 'int', since
8247 their values must fit in 'int'.
8248 (xpm_load_image, png_load, tiff_load):
8249 Invoke x_create_x_image_and_pixmap earlier,
8250 to avoid much needless work if the image is too large.
8251 (tiff_load): Treat overly large images as if
8252 x_create_x_image_and_pixmap failed, not as malloc failures.
8253 (gs_load): Use x_check_image_size.
8255 * gtkutil.c: Omit integer casts.
8256 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8257 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8259 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8261 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8262 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8263 would wrongly return t on a 64-bit host.
8265 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8266 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8267 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8268 and therefore cause GCC to emit a bogus diagnostic in some cases.
8270 * image.c: Integer signedness and overflow and related fixes.
8271 This is not an exhaustive set of fixes, but it's time to
8272 record what I've got.
8273 (lookup_pixel_color, check_image_size): Remove redundant decls.
8274 (check_image_size): Don't assume that arbitrary EMACS_INT values
8275 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8276 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8277 (tiff_load, imagemagick_load_image):
8278 Check for overflow in size calculations.
8279 (x_create_x_image_and_pixmap): Remove unnecessary test for
8280 xmalloc returning NULL; that can't happen.
8281 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8282 (xpm_color_bucket): Use better integer hashing function.
8283 (xpm_cache_color): Don't possibly over-allocate memory.
8284 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8285 (gif_memory_source):
8286 Use ptrdiff_t, not int or size_t, to record sizes.
8287 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8288 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8289 either works, as we prefer signed integers.
8290 (tiff_read_from_memory, tiff_write_from_memory):
8291 Return tsize_t, not size_t, since that's what the TIFF API wants.
8292 (tiff_read_from_memory): Don't fail simply because the read would
8293 go past EOF; instead, return a short read.
8294 (tiff_load): Omit no-longer-needed casts.
8295 (Fimagemagick_types): Don't assume size fits into 'int'.
8297 Improve hashing quality when configured --with-wide-int.
8298 * fns.c (hash_string): New function, taken from sxhash_string.
8299 Do not discard information about ASCII character case; this
8300 discarding is no longer needed.
8301 (sxhash-string): Use it. Change sig to match it. Caller changed.
8302 * lisp.h: Declare it.
8303 * lread.c (hash_string): Remove, since we now use fns.c's version.
8304 The fns.c version returns a wider integer if --with-wide-int is
8305 specified, so this should help the quality of the hashing a bit.
8307 * emacs.c: Integer overflow minor fix.
8308 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8309 Define only if GNU_LINUX.
8310 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8312 * dispnew.c: Integer signedness and overflow fixes.
8313 Remove unnecessary forward decls, that were a maintenance hassle.
8314 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8315 All uses changed.
8316 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8317 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8318 (prepare_desired_row, line_draw_cost):
8319 Use int, not unsigned, where either works.
8320 (save_current_matrix, restore_current_matrix):
8321 Use ptrdiff_t, not size_t, where either works.
8322 (init_display): Check for overflow more accurately, and without
8323 relying on undefined behavior.
8325 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8326 Remove, replacing with the new symbols in lisp.h. All uses changed.
8327 * fileio.c (make_temp_name):
8328 * filelock.c (lock_file_1, lock_file):
8329 * xdisp.c (message_dolog):
8330 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8331 Use pMd etc. instead.
8332 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8333 replacing the pWIDE etc. symbols removed from editfns.c.
8335 * keyboard.h (num_input_events): Now uintmax_t.
8336 This is (very slightly) less likely to mess up due to wraparound.
8337 All uses changed.
8339 * buffer.c: Integer signedness fixes.
8340 (alloc_buffer_text, enlarge_buffer_text):
8341 Use ptrdiff_t rather than size_t when either will do, as we prefer
8342 signed integers.
8344 * alloc.c: Integer signedness and overflow fixes.
8345 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8346 (__malloc_size_t): Default to size_t, not to int.
8347 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8348 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8349 Prefer ptrdiff_t to size_t when either would do, as we prefer
8350 signed integers.
8351 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8352 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8353 Now const. Initialize with values that are in range even if char
8354 is signed.
8355 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8356 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8357 These functions do the right thing with sizes > 2**32.
8358 (check_depth): Now ptrdiff_t, not int.
8359 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8360 Adjust to new way of storing sizes. Check for size overflow bugs
8361 in rest of code.
8362 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8363 slightly wrong anyway, as it missed one instance of
8364 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8365 (refill_memory_reserve): Omit needless cast to size_t.
8366 (mark_object_loop_halt): Mark as externally visible.
8368 * xselect.c: Integer signedness and overflow fixes.
8369 (Fx_register_dnd_atom, x_handle_dnd_message):
8370 Use ptrdiff_t, not size_t, since we prefer signed.
8371 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8372 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8373 x_dnd_atoms_size and x_dnd_atoms_length.
8375 * doprnt.c: Prefer signed to unsigned when either works.
8376 * eval.c (verror):
8377 * doprnt.c (doprnt):
8378 * lisp.h (doprnt):
8379 * xdisp.c (vmessage):
8380 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8381 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8382 prefer signed arithmetic to avoid comparison confusion.
8383 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8384 but is a bit tricky.
8386 Assume freestanding C89 headers, string.h, stdlib.h.
8387 * data.c, doprnt.c, floatfns.c, print.c:
8388 Include float.h unconditionally.
8389 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8390 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8391 * regex.c: Likewise for stddef.h, string.h.
8392 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8393 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8394 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8395 (STDC_HEADERS): Remove obsolete defines.
8396 * sysdep.c: Include limits.h unconditionally.
8398 Assume support for memcmp, memcpy, memmove, memset.
8399 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8400 * regex.c (memcmp, memcpy):
8401 Remove; we assume C89 now.
8403 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8404 (__malloc_safe_bcopy): Remove; no longer needed.
8406 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8407 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8408 well either way, and we prefer signed to unsigned.
8410 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8412 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8413 closes the connection while we're reading (bug#9182).
8415 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8417 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8418 are specified (Bug#9168).
8420 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8422 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8423 Found by GCC static checking and --with-wide-int on a 32-bit host.
8425 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8427 * xdisp.c (compute_display_string_pos): Fix logic of caching
8428 previous display string position. Initialize cached_prev_pos to
8429 -1. Fixes slow-down at the beginning of a buffer.
8431 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8433 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8434 for attrs[LFACE_FONTSET_INDEX].
8436 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8438 * xml.c (parse_region): Remove unused local
8439 that was recently introduced.
8441 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8443 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8444 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8446 * xdisp.c (move_it_in_display_line_to): Record the best matching
8447 position for TO_CHARPOS while scanning the line, and restore it on
8448 exit if none of the characters scanned was an exact match.
8449 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8450 when exact match is impossible due to invisible text, and the
8451 lines are truncated.
8453 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8455 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8456 for OSX >= 10.7.
8458 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8460 Fix a significant slow-down of cursor motion with C-n, C-p,
8461 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8462 auto-repeat under bidi redisplay in fontified buffers.
8463 * xdisp.c (compute_stop_pos_backwards): New function.
8464 (next_element_from_buffer): Call compute_stop_pos_backwards to
8465 find a suitable prev_stop when we find ourselves before
8466 base_level_stop.
8467 (reseat): Don't look for prev_stop, as that could mean a very long
8468 run.
8469 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8470 <cached_disp_overlay_modiff>: Cache for last found display string
8471 position.
8472 (compute_display_string_pos): Return the cached position if asked
8473 about the same buffer in the same area of character positions, and
8474 the buffer wasn't changed since the time the display string
8475 position was cached.
8477 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8479 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8480 is an integer, which is important for empty lines. (Bug#9149)
8482 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8484 * frame.c (Fmodify_frame_parameters): In tty case, update the
8485 default face if necessary (Bug#4238).
8487 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8489 * editfns.c (Fstring_to_char): No need to explain what a character
8490 is in the docstring (Bug#6576).
8492 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8494 * xml.c (parse_region): Make sure we always return a tree.
8496 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8498 * xml.c (parse_region): If a document contains only comments,
8499 return that, too.
8501 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8503 * xml.c (make_dom): Return comments, too.
8505 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8507 Port to OpenBSD.
8508 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8509 and the surrounding thread.
8510 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8511 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8512 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8513 timer goes off.
8514 * s/openbsd.h (BROKEN_SIGIO): Define.
8515 * unexelf.c (unexec) [__OpenBSD__]:
8516 Don't update the .mdebug section of the Alpha COFF symbol table.
8518 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8520 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8521 (bug#8460).
8523 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8525 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8526 This fixes some race conditions on the permissions of any newly
8527 created file.
8529 * alloc.c (valid_pointer_p): Use pipe, not open.
8530 This fixes some permissions issues when debugging.
8532 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8533 If fchown fails to set both uid and gid, try to set just gid,
8534 as that is sometimes allowed. Adjust the file's mode to eliminate
8535 setuid or setgid bits that are inappropriate if fchown fails.
8537 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8539 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8540 to compare Lisp_Objects.
8541 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8542 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8543 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8545 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8547 * lread.c (read_integer): Unread even EOF character.
8548 (read1): Likewise. Properly record start position of symbol.
8550 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8551 symbol character follows.
8553 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8555 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8556 This works around a problem with the previous change to Fcopy_file.
8557 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8558 and without this change, GCC might complain about discarding
8559 fchown's return value.
8561 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8563 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8565 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8567 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8569 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8571 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8572 it's used from the C level.
8574 * process.c: Use the same condition for POLL_FOR_INPUT in both
8575 keyboard.c and process.c (bug#1858).
8577 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8579 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8580 (Fgnutls_boot): Use it.
8582 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8584 * doc.c (Fsubstitute_command_keys): Revert last change.
8586 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8588 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8589 quotes the next character, and doesn't affect other longer
8590 sequences (bug#8935).
8592 * lread.c (syms_of_lread): Clarify that is isn't only
8593 `eval-buffer' and `eval-defun' that's affected by
8594 `lexical-binding' (bug#8460).
8596 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8598 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8599 bidi redisplay when a line includes both an image and is truncated.
8601 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8603 Fix minor problems found by static checking.
8604 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8605 (elsz): Now a signed constant, not a size_t var. We prefer signed
8606 types to unsigned, to avoid integer comparison confusion. Without
8607 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8608 "cannot optimize loop, the loop counter may overflow", a symptom
8609 of the confusion.
8610 * indent.c (Fvertical_motion): Mark locals as initialized.
8611 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8613 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8615 * search.c (Fre_search_backward): Mention `case-fold-search' in
8616 all the re_search_* functions (bug#8138).
8618 * keyboard.c (Fopen_dribble_file): Document when the file is
8619 closed (bug#8056).
8621 2011-07-14 Eli Zaretskii <eliz@gnu.org>

8624 bidi_cache_idx.
8626 Support bidi reordering of display and overlay strings.

8636 buffer position was specified. Initialize paragraph_embedding to
8637 L2R.
8638 (reseat_to_string): Initialize the bidi iterator.
8639 (display_string): If we need to ignore text properties of
8640 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8641 original value of -1 will not work with bidi.)
8642 (compute_display_string_pos): First arg is now struct
8643 `text_pos *'; all callers changed. Support display properties on
8644 Lisp strings.
8645 (compute_display_string_end): Support display properties on Lisp
8646 strings.
8647 (init_iterator, reseat_1, reseat_to_string): Initialize the
8648 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8649 when iterating on a string not from display properties).
8650 (compute_display_string_pos, compute_display_string_end):
8651 Fix calculation of the object to scan. Fixes an error when using
8652 arrow keys.
8653 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8654 base_level_stop; instead, set base_level_stop to BEGV.
8655 Fixes crashes in vertical-motion.
8656 (next_element_from_buffer): Improve commentary for when
8657 the iterator is before prev_stop.
8658 (init_iterator): Initialize bidi_p from the default value of
8659 bidi-display-reordering, not from buffer-local value. Use the
8660 buffer-local value only if initializing for buffer iteration.
8661 (handle_invisible_prop): Support invisible properties on strings
8662 that are being bidi-reordered.
8663 (set_iterator_to_next): Support bidi reordering of C strings and

8666 strings.
8667 (handle_stop_backwards): Support Lisp strings as well.
8668 (display_string): Support display of R2L glyph rows.
8669 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8670 (init_iterator): Don't initialize it->bidi_p for strings
8671 here.
8672 (reseat_to_string): Initialize it->bidi_p for strings here.

8678 (next_element_from_c_string): Handle the case of the first string
8679 character that is not the first one in the visual order.
8680 (get_visually_first_element): New function, refactored from common
8681 parts of next_element_from_buffer, next_element_from_string, and
8682 next_element_from_c_string.
8683 (tool_bar_lines_needed, redisplay_tool_bar)
8684 (display_menu_bar): Force left-to-right direction. Add a FIXME
8685 comment for making that be controlled by a user option.
8686 (push_it, pop_it): Save and restore the state of the
8687 bidi iterator. Save and restore the bidi_p flag.
8688 (pop_it): Iterate out of display property for string iteration as

8691 (handle_single_display_spec): Set up it->bidi_it for iteration
8692 over a display string, and call bidi_init_it.
8693 (handle_single_display_spec, next_overlay_string)
8694 (get_overlay_strings_1, push_display_prop): Set up the bidi
8695 iterator for displaying display or overlay strings.
8696 (forward_to_next_line_start): Don't use the shortcut if
8697 bidi-iterating.
8698 (back_to_previous_visible_line_start): If handle_display_prop
8699 pushed the iterator stack, restore the internal state of the bidi
8700 iterator by calling bidi_pop_it same number of times.
8701 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8702 and we are bidi-iterating, don't decrement the iterator position;
8703 instead, set the first_elt flag in the bidi iterator, to produce
8704 the same effect.
8705 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8706 (push_display_prop): xassert that we are iterating a buffer.
8707 (push_it, pop_it): Save and restore paragraph_embedding member.
8708 (handle_single_display_spec, next_overlay_string)
8709 (get_overlay_strings_1, reseat_1, reseat_to_string)
8710 (push_display_prop): Set up the `unibyte' member of bidi_it.string
8711 correctly. Don't assume unibyte strings are not bidi-reordered.

8713 (compute_display_string_end): Fix handling the case of C string.
8714 (push_it, pop_it): Save and restore from_disp_prop_p.

8716 from_disp_prop_p flag.
8717 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
8718 (pop_it): Call iterate_out_of_display_property only if we are
8719 popping after iteration over a string that came from a display
8720 property. Fix a typo in popping stretch info. Add an assertion
8721 for verifying that the iterator position is in sync with the bidi
8722 iterator.

8724 (push_display_prop): Fix initialization of paragraph direction for
8725 string when that of the parent object is not yet determined.
8726 (reseat_1): Call bidi_init_it to resync the bidi
8727 iterator with IT's position. (Bug#7616)
8728 (find_row_edges): If ROW->start.pos gives position
8729 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
8730 (handle_stop, back_to_previous_visible_line_start, reseat_1):
8731 Reset the from_disp_prop_p flag.
8732 (SAVE_IT, RESTORE_IT): New macros.
8733 (pos_visible_p, face_before_or_after_it_pos)
8734 (back_to_previous_visible_line_start)
8735 (move_it_in_display_line_to, move_it_in_display_line)
8736 (move_it_to, move_it_vertically_backward, move_it_by_lines)
8737 (try_scrolling, redisplay_window, display_line): Use them when
8738 saving a temporary copy of the iterator and restoring it back.
8739 (back_to_previous_visible_line_start, reseat_1)
8740 (init_iterator): Empty the bidi cache "stack".
8741 (move_it_in_display_line_to): If iterator ended up at
8742 EOL, but we never saw any buffer positions smaller than
8743 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
8744 motion in bidi-reordered lines.
8745 (move_it_in_display_line_to): Record prev_method and prev_pos
8746 immediately before the call to set_iterator_to_next. Fixes cursor
8747 motion in bidi-reordered lines with stretch glyphs and strings
8748 displayed in margins. (Bug#8133) (Bug#8867)
8749 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
8750 TO_CHARPOS.
8751 (pos_visible_p): Support positions in bidi-reordered lines.
8752 Save and restore bidi cache.
8754 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
8755 (bidi_paragraph_info): Delete unused struct.
8756 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
8757 (bidi_cache_start): New variable.
8758 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
8759 to zero.
8760 (bidi_cache_fetch_state, bidi_cache_search)
8761 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8762 (bidi_cache_find, bidi_peek_at_next_level)

8775 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
8776 can now be zero (for strings); special values 0 and -1 were
8777 changed to -1 and -2, respectively.
8778 (bidi_char_at_pos): New function.
8779 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

8790 (bidi_initialize): Initialize the bidi cache start stack pointer.
8791 (bidi_cache_ensure_space): New function, refactored from part of

8805 All variables related to cache indices are now EMACS_INT.
8807 * dispextern.h (struct bidi_string_data): New structure.
8808 (struct bidi_it): New member `string'. Make flag members be 1-bit
8809 fields, and put them last in the struct.
8810 (compute_display_string_pos, compute_display_string_end):
8811 Update prototypes.
8812 (bidi_push_it, bidi_pop_it): Add prototypes.
8813 (struct iterator_stack_entry): New members bidi_p,
8814 paragraph_embedding, and from_disp_prop_p.
8815 (struct it): Member bidi_p is now a bit field 1 bit wide.
8816 (bidi_shelve_cache, bidi_unshelve_cache):
8817 Declare prototypes.
8819 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

8861 (x_handle_selection_clear,x_clear_frame_selections):
8862 Pass Qx_lost_selection_functions rather than
8863 Vx_lost_selection_functions to Frun_hook_with_args.
8865 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
8867 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
8868 The old code sometimes used this field without initializing it.
8870 * alloc.c (gc_sweep): Don't read past end of array.
8871 In theory, the old code could also have corrupted Emacs internals,
8872 though it'd be very unlikely.
8874 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
8876 * character.c (Fcharacterp): Don't advertise optional ignored
8877 argument. (Bug#4026)
8879 2011-07-12 Lars Magne Ingebrigtsen <larsi@gnus.org>
8881 * keymap.c (syms_of_keymap): Clarify that "modifier" is "modifier
8882 key" (bug#4257).
8884 * window.c (Fset_window_start): Doc fix (bug#4199).
8885 (Fset_window_hscroll): Ditto.
8887 2011-07-12 Paul Eggert <eggert@cs.ucla.edu>

8895 2011-07-12 Chong Yidong <cyd@stupidchicken.com>
8897 * xdisp.c (Vresize_mini_windows): Minor doc fix (Bug#3300).

8902 are the mini-buffer and the echo area (bug#3320).
8904 * term.c (init_tty): Remove support for supdup, c10 and perq
8905 terminals, which are no longer supported (bug#1482).

9135 (clone_per_buffer_values): Don't assume that

9137 This isn't true in general, and it's particularly not true
9138 if Emacs is configured with --with-wide-int.
9139 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
9140 New macros, used in the buffer.c change.

9176 Random fixes. E.g., (random) never returned negative values.
9177 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9178 subseconds part to the entropy, as that's a bit more random.
9179 Prefer signed to unsigned, since the signedness doesn't matter and
9180 in general we prefer signed. When given a limit, use a
9181 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9182 latter isn't right if USE_2_TAGS_FOR_INTS.
9183 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9184 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9186 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9188 * textprop.c (text_property_stickiness):

9196 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9197 This is more efficient than Ffile_directory_p and avoids a minor race.
9199 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9201 * buffer.c (Foverlay_put): Say what the return value is
9202 (bug#7835).
9204 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9205 is a directory before asking whether to use the file name
9206 (bug#7564).
9207 (barf_or_query_if_file_exists): Make the "File is a directory"
9208 error be more correct.
9210 * fns.c (Frequire): Remove the mention of the .gz files, since
9211 that's installation-specific, but keep the mention of
9212 `get-load-suffixes'.
9214 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9216 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9227 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9228 Also (re)move comments that are misplaced or no longer relevant.
9230 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

9291 (syms_of_keymap): Defsubr make-composed-keymap.
9292 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
9293 (parse_menu_item): Trivial simplification.
9295 2011-07-01 Glenn Morris <rgm@gnu.org>

9321 (xgselect_initialize): Ditto.
9323 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h
9324 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
9325 xg_select.
9327 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9329 * eval.c (struct backtrace): Simplify and port the data structure.
9330 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9331 signed bit field, as this assumption is not portable and it makes
9332 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9333 "char debug_on_exit : 1" as this is not portable either; instead,
9334 use the portable "unsigned int debug_on_exit : 1". Remove unused
9335 member evalargs. Remove obsolete comments about cc bombing out.
9337 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9501 Integer and buffer overflow fixes (Bug#8873).
9503 * print.c (printchar, strout): Check for string overflow.
9504 (PRINTPREPARE, printchar, strout):
9505 Don't set size unless allocation succeeds.
9507 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9508 for sizes. Check for string overflow more accurately.
9509 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
9511 * macros.c: Integer and buffer overflow fixes.
9512 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9513 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

9519 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9521 * lread.c: Integer overflow fixes.
9522 (read_integer): Radix is now EMACS_INT, not int,
9523 to improve quality of diagnostics for out-of-range radices.
9524 Calculate buffer size correctly for out-of-range radices.
9525 (read1): Check for integer overflow in radices, and in
9526 read-circle numbers.
9527 (read_escape): Avoid int overflow.
9528 (Fload, openp, read_buffer_size, read1)
9529 (substitute_object_recurse, read_vector, read_list, map_obarray):

9545 2011-06-22 Leo Liu <sdl.web@gmail.com>
9547 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9548 Move to minibuffer.el.
9550 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9552 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9553 The following patches are for when GLYPH_DEBUG && !XASSERT.
9554 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9555 * dispnew.c (flush_stdout):
9556 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9557 Mark as externally visible.
9558 * dispnew.c (check_window_matrix_pointers): Now static.
9559 * dispnew.c (window_to_frame_vpos):
9560 * xfns.c (unwind_create_frame):
9561 * xterm.c (x_check_font): Remove unused local.
9562 * scroll.c (CHECK_BOUNDS):
9563 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9564 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9565 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9566 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9567 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9568 Now static.
9569 (debug_method_add): Use va_list and vsprintf rather than relying
9570 on undefined behavior with wrong number of arguments.
9571 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9572 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9573 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9574 since we're not interested in debugging glyphs with old libraries.
9575 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9576 GCC 4.6.0's static checking.
9578 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9580 Integer overflow and signedness fixes (Bug#8873).

9592 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9593 (.bitmaps_last):
9594 * xfaces.c (load_pixmap):
9595 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9596 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9597 (.bitmaps_last, struct x_output.icon_bitmap):
9598 Use ptrdiff_t, not int, for bitmap indexes.
9599 (x_allocate_bitmap_record): Check for size overflow.
9600 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9602 Use ptrdiff_t, not int, for overlay counts.
9603 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9604 * editfns.c (overlays_around, get_pos_property):
9605 * textprop.c (get_char_property_and_overlay):
9606 * xdisp.c (next_overlay_change, note_mouse_highlight):
9607 * xfaces.c (face_at_buffer_position):
9608 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9609 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9610 (Fnext_overlay_change, Fprevious_overlay_change)
9611 (mouse_face_overlay_overlaps, Foverlays_in):
9612 Use ptrdiff_t, not int, for sizes.
9613 (overlays_at, overlays_in): Check for size-calculation overflow.
9615 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9617 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9618 (x_session_initialize): Do not assume string length fits in int.
9620 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9621 This is unlikely, but can occur if DPI is outlandish.
9623 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9624 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9626 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9627 * xrdb.c (magic_file_p, search_magic_path):
9628 Omit last arg SUFFIX; it was always 0. All callers changed.

9636 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9637 not unsigned long, as we prefer signed integers. All callers changed.
9638 Detect integer overflow in repeat count.
9639 (message_dolog): Don't assume print length fits in 39 bytes.
9640 (display_mode_element): Don't assume strlen fits in int.
9642 * termcap.c: Don't assume sizes fit in int and never overflow.
9643 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9644 (gobble_line): Check for size-calculation overflow.
9646 * minibuf.c (Fread_buffer):
9647 * lread.c (intern, intern_c_string):
9648 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9649 Don't assume string length fits in int.

9661 * filelock.c: Fix some buffer overrun and integer overflow issues.
9662 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9663 Reformulate so as not to need the command string.
9664 Invoke gzip -cd rather than gunzip, as it's more portable.
9665 (lock_info_type, lock_file_1, lock_file):
9666 Don't assume pid_t and time_t fit in unsigned long.
9667 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9668 (current_lock_owner): Prefer signed type for sizes.
9669 Use memcpy, not strncpy, where memcpy is what is really wanted.
9670 Don't assume (via atoi) that time_t and pid_t fit in int.
9671 Check for time_t and/or pid_t out of range, e.g., via a network share.
9672 Don't alloca where an auto var works fine.
9674 * fileio.c: Fix some integer overflow issues.
9675 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9676 Don't assume string length fits in int.
9677 (directory_file_name): Don't assume string length fits in long.

9679 length is less than 20.
9681 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9683 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9685 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

9699 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9701 * lread.c (invalid_syntax): Omit length argument.
9702 All uses changed. This doesn't fix a bug, but it simplifies the
9703 code away from its former Hollerith-constant appearance, and it's
9704 one less 'int' to worry about when looking at integer-overflow issues.
9705 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9707 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9708 This didn't break anything, but it didn't help either.
9709 It's confusing to put a bogus integer in a place where the actual
9710 value does not matter.
9711 (LIST_END_P): Remove unused macro and its bogus comment.
9712 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9714 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9715 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9716 implementation.
9717 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9718 We prefer signed types, and the value cannot exceed the EMACS_INT
9719 range anyway (because otherwise the length would not be representable).
9720 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9721 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9722 This avoids a GCC warning when WIDE_EMACS_INT.
9724 * indent.c (sane_tab_width): New function.
9725 (current_column, scan_for_column, Findent_to, position_indentation)
9726 (compute_motion): Use it. This is just for clarity.
9727 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9729 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9731 * lisp.h (lint_assume): New macro.
9732 * composite.c (composition_gstring_put_cache):
9733 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9735 * editfns.c, insdel.c:
9736 Omit unnecessary forward decls, to simplify future changes.
9738 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9740 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9742 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9743 Use much-faster test for byte-length change.
9744 Don't assume string byte-length fits in 'int'.
9745 Check that character arg fits in 'int'.
9746 (mapcar1): Declare byte as byte, for clarity.
9748 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9750 * fns.c (concat): Catch string overflow earlier.
9751 Do not rely on integer wraparound.
9753 * dispextern.h (struct it.overlay_strings_charpos)
9754 (struct it.selective): Now EMACS_INT, not int.
9755 * xdisp.c (forward_to_next_line_start)
9756 (back_to_previous_visible_line_start)
9757 (reseat_at_next_visible_line_start, next_element_from_buffer):
9758 Don't arbitrarily truncate the value of 'selective' to int.
9760 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9762 * composite.c: Don't truncate sizes to 'int'.
9763 (composition_gstring_p, composition_reseat_it)
9764 (composition_adjust_point): Use EMACS_INT, not int.
9765 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9766 not EMACS_UINT, for indexes.
9768 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9770 * buffer.c: Include <verify.h>.
9771 (struct sortvec.priority, struct sortstr.priority):
9772 Now EMACS_INT, not int.
9773 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9774 (struct sortstr.size, record_overlay_string)
9775 (struct sortstrlist.size, struct sortlist.used):
9776 Don't truncate size to int.
9777 (record_overlay_string): Check for size-calculation overflow.
9778 (init_buffer_once): Check at compile-time, not run-time.
9780 2011-06-22 Jim Meyering <meyering@redhat.com>
9782 Don't leak an XBM-image-sized buffer
9783 * image.c (xbm_load): Free the image buffer after using it.
9785 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9787 Port to Sun C.
9788 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9789 that Sun C diagnosed.
9790 * fns.c (secure_hash): Fix pointer signedness issue.
9791 * intervals.c (static_offset_intervals): New function.
9792 (offset_intervals): Use it.
9794 2011-06-21 Leo Liu <sdl.web@gmail.com>
9796 * deps.mk (fns.o):
9797 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9798 sha512.h.
9800 * fns.c (secure_hash): Rename from crypto_hash_function and change
9801 the first arg to accept symbols.
9802 (Fsecure_hash): New primitive.
9803 (syms_of_fns): New symbols.
9805 2011-06-20 Deniz Dogan <deniz@dogan.se>
9807 * process.c (Fset_process_buffer): Clarify return value in
9808 docstring.
9810 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9812 * dispnew.c (add_window_display_history): Use BVAR.
9814 * xdisp.c (debug_method_add): Use BVAR.
9815 (check_window_end, dump_glyph_matrix, dump_glyph)
9816 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9818 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9819 Likewise.
9821 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9822 check till after the cache is created in init_frame_faces.
9824 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9826 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9828 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9830 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9831 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9832 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9834 Improve buffer-overflow checking (Bug#8873).
9835 * fileio.c (Finsert_file_contents):
9836 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9837 Remove the old (too-loose) buffer overflow checks.
9838 They weren't needed, since make_gap checks for buffer overflow.
9839 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9840 The old code merely checked for Emacs fixnum overflow, and relied
9841 on undefined (wraparound) behavior. The new code avoids undefined
9842 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9844 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9845 Tune. Don't use wider integers than needed. Don't use alloca.
9846 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9848 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9850 * insdel.c, lisp.h (buffer_overflow): New function.
9851 (insert_from_buffer_1, replace_range, replace_range_2):
9852 * insdel.c (make_gap_larger):
9853 * editfns.c (Finsert_char):
9854 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9856 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9858 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9860 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9862 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9863 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9865 * fileio.c: Don't assume EMACS_INT fits in off_t.
9866 (emacs_lseek): New static function.
9867 (Finsert_file_contents, Fwrite_region): Use it.
9868 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9870 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9872 * fns.c: Don't overflow int when computing a list length.
9873 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9874 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9875 truncation on 64-bit hosts. Check for QUIT every
9876 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9877 faster and is responsive enough.
9878 (Flength): Report an error instead of overflowing an integer.
9879 (Fsafe_length): Return a float if the value is not representable
9880 as a fixnum. This shouldn't happen except in contrived situations.
9881 (Fnthcdr, Fsort): Don't assume list length fits in int.
9882 (Fcopy_sequence): Don't assume vector length fits in int.
9884 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9885 (header_size, word_size): New constants.
9886 (allocate_vectorlike): Don't check size overflow here.
9887 (allocate_vector): Check it here instead, since this is the only
9888 caller of allocate_vectorlike that could cause overflow.
9889 Check that the new vector's length is representable as a fixnum.
9891 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9892 The previous code was bogus. For example, next_almost_prime (32)
9893 returned 39, which is undesirable as it is a multiple of 3; and
9894 next_almost_prime (24) returned 25, which is a multiple of 5 so
9895 why was the code bothering to check for multiples of 7?
9897 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9899 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9901 Variadic C functions now count arguments with ptrdiff_t.
9902 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9903 Back then I didn't know that the Emacs coding style prefers signed int.
9904 Also, in the meantime I found a few more instances where arguments
9905 were being counted with int, which may truncate counts on 64-bit
9906 machines, or EMACS_INT, which may be unnecessarily wide.
9907 * lisp.h (struct Lisp_Subr.function.aMANY)
9908 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9909 Arg counts are now ptrdiff_t, not size_t.
9910 All variadic functions and their callers changed accordingly.
9911 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9912 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9913 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9914 * callint.c (Fcall_interactively): Check arg count for overflow,
9915 to avoid potential buffer overrun. Use signed char, not 'int',
9916 for 'varies' array, so that we needn't bother to check its size
9917 calculation for overflow.
9918 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9919 * eval.c (apply_lambda):
9920 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9921 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9922 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9924 * callint.c (Fcall_interactively): Don't use index var as event count.
9926 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9927 * mem-limits.h (SIZE): Remove; no longer used.
9929 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9931 Remove unnecessary casts.
9932 * xterm.c (x_term_init):
9933 * xfns.c (x_set_border_pixel):
9934 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9935 These aren't needed now that we assume ANSI C.
9937 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9938 It's more likely to cause problems (due to unsigned overflow)
9939 than to cure them.
9941 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9943 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9945 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9947 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9949 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9951 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9953 GLYPH_CODE_FACE returns EMACS_INT, not int.
9954 * dispextern.h (merge_faces):
9955 * xfaces.c (merge_faces):
9956 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9957 Don't assume EMACS_INT fits in int.
9959 * character.h (CHAR_VALID_P): Remove unused parameter.
9960 * fontset.c, lisp.h, xdisp.c: All uses changed.
9962 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9964 * fns.c (concat): Minor tuning based on overflow analysis.
9965 This doesn't fix any bugs. Use int to hold character, instead
9966 of constantly refetching from Emacs object. Use XFASTINT, not
9967 XINT, for value known to be a character. Don't bother comparing
9968 a single byte to 0400, as it's always less.
9970 * floatfns.c (Fexpt):
9971 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9973 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9974 for characters.
9976 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9978 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9979 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9980 incorrectly succeed when S was a string, because 4294967386 was
9981 truncated before it was used.
9983 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9984 Otherwise, an out-of-range integer could cause undefined behavior
9985 on a 64-bit host.
9987 * composite.c: Use int, not EMACS_INT, for characters.
9988 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9989 EMACS_INT, for values that are known to be in character range.
9990 This doesn't fix any bugs but is the usual style inside Emacs and
9991 may generate better code on 32-bit machines.
9993 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9994 This is for reasons similar to the recent CHAR_STRING fix.
9995 * charset.c (Fencode_char): Check that character arg is actually
9996 a character. Pass an int to ENCODE_CHAR.
9997 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9998 wider than 'int', as a compile-time check to prevent future regressions
9999 in this area.
10001 * character.c (char_string): Remove unnecessary casts.
10003 Make sure a 64-bit char is never passed to CHAR_STRING.
10004 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10005 by silently ignoring the top 32 bits, allowing some values
10006 that were far too large to be valid characters.
10007 * character.h: Include <verify.h>.
10008 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10009 arguments are no wider than unsigned, as a compile-time check
10010 to prevent future regressions in this area.
10011 * data.c (Faset):
10012 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10013 (Fsubst_char_in_region):
10014 * fns.c (concat):
10015 * xdisp.c (decode_mode_spec_coding):
10016 Adjust to CHAR_STRING's new requirement.
10017 * editfns.c (Finsert_char, Fsubst_char_in_region):
10018 * fns.c (concat): Check that character args are actually
10019 characters. Without this test, these functions did the wrong
10020 thing with wildly out-of-range values on 64-bit hosts.
10022 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10023 These casts should not be needed on 32-bit hosts, either.
10024 * keyboard.c (read_char):
10025 * lread.c (Fload): Remove casts to unsigned.
10027 * lisp.h (UNSIGNED_CMP): New macro.
10028 This fixes comparison bugs on 64-bit hosts.
10029 (ASCII_CHAR_P): Use it.
10030 * casefiddle.c (casify_object):
10031 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10032 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10033 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10034 * dispextern.h (FACE_FROM_ID):
10035 * keyboard.c (read_char): Use UNSIGNED_CMP.
10037 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10038 not to EMACS_INT, to avoid GCC warning.
10040 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10042 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10043 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10044 isn't needed on 32-bit machines.
10046 * buffer.c (Fgenerate_new_buffer_name):
10047 Use EMACS_INT for count, not int.
10048 (advance_to_char_boundary): Return EMACS_INT, not int.
10050 * data.c (Qcompiled_function): Now static.
10052 * window.c (window_body_lines): Now static.
10054 * image.c (gif_load): Rename local to avoid shadowing.
10056 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10057 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10058 * alloc.c (make_save_value): Integer argument is now of type
10059 ptrdiff_t, not int.
10060 (mark_object): Use ptrdiff_t, not int.
10061 * lisp.h (pD): New macro.
10062 * print.c (print_object): Use it.
10064 * alloc.c: Use EMACS_INT, not int, to count objects.
10065 (total_conses, total_markers, total_symbols, total_vector_size)
10066 (total_free_conses, total_free_markers, total_free_symbols)
10067 (total_free_floats, total_floats, total_free_intervals)
10068 (total_intervals, total_strings, total_free_strings):
10069 Now EMACS_INT, not int. All uses changed.
10070 (Fgarbage_collect): Compute overall total using a double, so that
10071 integer overflow is less likely to be a problem. Check for overflow
10072 when converting back to an integer.
10073 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10074 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10075 These were 'int' variables that could overflow on 64-bit hosts;
10076 they were never used, so remove them instead of repairing them.
10077 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10078 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10079 Previously, this ceilinged at INT_MAX, but that doesn't work on
10080 64-bit machines.
10081 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10083 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10084 (allocate_vectorlike): Check for ptrdiff_t overflow.
10085 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10086 when a (possibly-narrower) signed value would do just as well.
10087 We prefer using signed arithmetic, to avoid comparison confusion.
10089 * alloc.c: Catch some string size overflows that we were missing.
10090 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10091 for convenience in STRING_BYTES_MAX.
10092 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10093 The definition here is exact; the one in lisp.h was approximate.
10094 (allocate_string_data): Check for string overflow. This catches
10095 some instances we weren't catching before. Also, it catches
10096 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10097 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10098 and ptrdiff_t and EMACS_INT are both 64 bits.
10100 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10101 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10102 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10104 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10106 * alloc.c (Fmake_string): Check for out-of-range init.
10108 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10110 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10112 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10114 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10115 xg_get_default_scrollbar_width.
10117 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10118 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10119 (style_changed_cb): Call update_theme_scrollbar_width and call
10120 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10121 all frames (Bug#8505).
10122 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10123 Call gtk_window_set_resizable if HAVE_GTK3.
10124 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10125 and height if HAVE_GTK3 (Bug#8505).
10126 (scroll_bar_width_for_theme): New variable.
10127 (update_theme_scrollbar_width): New function.
10128 (xg_get_default_scrollbar_width): Move code to
10129 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10130 (xg_initialize): Call update_theme_scrollbar_width.
10132 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10134 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10136 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10138 * frame.c (make_frame): Call other_buffer_safely instead of
10139 other_buffer.
10141 * window.c (temp_output_buffer_show): Call display_buffer with
10142 second argument Vtemp_buffer_show_specifiers and reset latter
10143 immediately after the call.
10144 (Vtemp_buffer_show_specifiers): New variable.
10145 (auto_window_vscroll_p, next_screen_context_lines)
10146 (Vscroll_preserve_screen_position): Remove leading asterisks from
10147 doc-strings.
10149 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10151 Fix minor problems found by GCC 4.6.0 static checking.
10152 * buffer.c (Qclone_number): Remove for now, as it's unused.
10153 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10154 (record_buffer): Remove unused local.
10155 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10156 (set_frame_buffer_list): Remove; unused.
10157 * frame.h (other_visible_frames): Remove decl.
10158 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10159 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10160 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10161 if HAVE_GPM.
10162 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10163 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10164 Define only if HAVE_GPM.
10165 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10166 (update_hints_inhibit): Remove; never set. All uses removed.
10167 * widgetprv.h (emacsFrameClassRec): Remove decl.
10168 * window.c (delete_deletable_window): Now returns void, since it
10169 wasn't returning anything.
10170 (compare_window_configurations): Remove unused locals.
10171 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10172 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10173 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10174 the same widths as pointers. This follows up on the 2011-05-06 patch.
10175 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10176 * xterm.h: Likewise.
10177 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10179 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10181 * makefile.w32-in: Update dependencies.
10182 (LISP_H): Add lib/intprops.h.
10184 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10186 * image.c (gif_load): Add animation frame delay to the metadata.
10187 (syms_of_image): Use DEFSYM. New symbol `delay'.
10189 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10191 * window.c (delete_deletable_window): Re-add.
10192 (Fset_window_configuration): Rewrite to handle dead buffers and
10193 consequently deletable windows.
10194 (window_tree, Fwindow_tree): Remove. Supply functionality in
10195 window.el.
10196 (compare_window_configurations): Simplify code.
10198 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10200 * image.c (imagemagick_load_image): Fix type mismatch.
10201 (Fimagemagick_types): Likewise.
10203 * window.h (replace_buffer_in_windows): Declare.
10205 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10207 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10208 Qclone_number. Remove external declaration of Qdelete_window.
10209 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10210 code.
10211 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10212 Run Qbuffer_list_update_hook if allowed.
10213 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10214 buffer list implementation.
10215 (other_buffer_safely): New function.
10216 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10217 calls to replace_buffer_in_windows and
10218 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10219 if allowed.
10220 (record_buffer): Inhibit quitting and rewrite using quittable
10221 functions. Run Qbuffer_list_update_hook if allowed.
10222 (Frecord_buffer, Funrecord_buffer): New functions.
10223 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10224 Move switch-to-buffer to window.el.
10225 (bury-buffer): Move to window.el.
10226 (Vbuffer_list_update_hook): New variable.
10228 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10229 section.
10231 * window.h (resize_frame_windows): Move up in code.
10232 (Fwindow_frame): Remove EXFUN.
10233 (replace_buffer_in_all_windows): Remove prototype.
10234 (replace_buffer_in_windows_safely): Add prototype.
10236 * window.c: Declare Qdelete_window static again. Move down
10237 declaration of select_count.
10238 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10239 (Fother_window): Move to window.el.
10240 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10241 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10242 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10243 window.el.

10679 instead of using explicit *_CHAR codes.
10680 (bidi_resolve_explicit, bidi_resolve_weak):
10681 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10682 bidirectional text is supported only in multibyte buffers.
10683 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
10684 it to initialize the frame_window_p member of struct bidi_it.
10685 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
10686 (bidi_resolve_explicit, bidi_resolve_weak)
10687 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
10688 bidi_it->nchars is non-positive.
10689 (bidi_level_of_next_char): Don't try to lookup the cache for the
10690 next/previous character if nothing is cached there yet, or if we
10691 were just reseat()'ed to a new position.
10693 * xdisp.c (set_cursor_from_row): Set start and stop points
10694 according to the row's direction when priming the loop that looks
10695 for the glyph on which to display cursor.
10696 (single_display_spec_intangible_p): Function deleted.
10697 (display_prop_intangible_p): Reimplement to call
10698 handle_display_spec instead of single_display_spec_intangible_p.
10699 Accept 3 additional arguments needed by handle_display_spec.
10700 This fixes incorrect cursor motion across display property with complex
10701 values: lists, `(when COND...)' forms, etc.
10702 (single_display_spec_string_p): Support property values that are
10703 lists with the argument STRING its top-level element.
10704 (display_prop_string_p): Fix the condition for processing a
10705 property that is a list to be consistent with handle_display_spec.
10706 (handle_display_spec): New function, refactored from the
10707 last portion of handle_display_prop.
10708 (compute_display_string_pos): Accept additional argument
10709 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10710 value of a `display' property is a "replacing spec".
10711 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10712 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10713 the display property, but just return a value indicating whether
10714 the display property will replace the characters it covers.
10715 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10716 frame_window_p members of struct bidi_it.
10717 (compute_display_string_pos, compute_display_string_end):
10718 New functions.
10719 (push_it): Accept second argument POSITION, where pop_it should
10720 jump to continue iteration.
10721 (reseat_1): Initialize bidi_it.disp_pos.
10723 * keyboard.c (adjust_point_for_property): Adjust the call to
10724 display_prop_intangible_p to its new signature.
10726 * dispextern.h (struct bidi_it): New member frame_window_p.
10727 (bidi_init_it): Update prototypes.
10728 (display_prop_intangible_p): Update prototype.
10729 (compute_display_string_pos, compute_display_string_end):
10730 Declare prototypes.
10731 (struct bidi_it): New members nchars and disp_pos. ch_len is now
10732 EMACS_INT.
10734 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
10736 Malloc failure behavior now depends on size of allocation.
10737 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
10738 * lisp.h: Change signatures accordingly.
10739 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
10740 All callers changed. (Bug#8762)
10742 * gnutls.c: Use Emacs's memory allocators.
10743 Without this change, the gnutls library would invoke malloc etc.
10744 directly, which causes problems on non-SYNC_INPUT hosts, and which
10745 runs afoul of improving memory_full behavior. (Bug#8761)
10746 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10747 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10748 xfree instead of the default malloc, realloc, free.
10749 (Fgnutls_boot): No need to check for memory allocation failure,
10750 since xmalloc does that for us.
10752 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
10753 * category.c (hash_get_category_set):
10754 * ccl.c (ccl_driver):

10766 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
10767 (Fsxhash, Fgethash, Fputhash, Fmaphash):
10768 * image.c (make_image, search_image_cache, lookup_image)
10769 (xpm_put_color_table_h):
10770 * lisp.h (struct Lisp_Hash_Table):
10771 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
10772 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10773 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10774 * alloc.c (allocate_vectorlike):
10775 Check for overflow in vector size calculations.
10776 * ccl.c (ccl_driver):
10777 Check for overflow when converting EMACS_INT to int.
10778 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10779 need to be updated by these changes.
10780 * fns.c (make_hash_table, maybe_resize_hash_table):
10781 Check for integer overflow with large hash tables.
10782 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10783 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10784 (SXHASH_REDUCE): New macro.
10785 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10786 Use it instead of discarding useful hash info with large hash values.
10787 (sxhash_float): New function.
10788 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10789 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10790 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10791 Rewrite to use FIXNUM_BITS, as this simplifies things.
10792 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10793 Adjust signatures to match updated version of code.
10794 (consing_since_gc): Now EMACS_INT, since a single hash table can
10795 use more than INT_MAX bytes.
10797 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
10799 Make it possible to build with GCC-4.6+ -O2 -flto.
10801 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
10803 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
10805 * minibuf.c (get_minibuffer, read_minibuf_unwind):
10806 Call minibuffer-inactive-mode.
10808 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
10810 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
10811 Update dependencies.
10813 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10815 * data.c (init_data): Remove code for UTS, this system is not
10816 supported anymore.
10818 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10820 Don't force ./temacs to start in terminal mode.
10822 * frame.c (make_initial_frame): Initialize faces in all cases, not
10823 only when CANNOT_DUMP is defined.
10824 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10826 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10828 * dispnew.c (add_window_display_history): Use const for the string
10829 pointer. Remove declaration, not needed.
10831 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10833 Use 'inline', not 'INLINE'.
10834 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10835 * alloc.c, fontset.c (INLINE): Remove.
10836 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10837 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10838 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10839 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10840 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10842 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10844 Make it possible to run ./temacs.
10846 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10847 syms_of_callproc does the same thing. Remove test for
10848 "initialized", do it in the caller.
10849 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10851 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10853 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10854 (read_minibuf): Use get_minibuffer.
10855 (syms_of_minibuf): Use DEFSYM.
10856 (Qmetadata): New var.
10857 * data.c (Qbuffer): Don't make it static.
10858 (syms_of_data): Use DEFSYM.
10860 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10862 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10863 (CCL_CODE_MIN): New macro.
10865 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10867 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10869 * eval.c (Qdebug): Now static.
10870 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10871 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10872 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10874 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10876 * image.c: Various fixes to ImageMagick code comments.
10877 (Fimagemagick_types): Doc fix.
10879 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10881 Minor fixes prompted by GCC 4.6.0 warnings.
10883 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10885 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10886 (x_clipboard_manager_save_all): Move extern decl to ...
10887 * xterm.h: ... here, so that it can be checked for consistency.
10889 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10891 * xselect.c (x_clipboard_manager_save_frame)
10892 (x_clipboard_manager_save_all): New functions.
10893 (Fx_clipboard_manager_save): Lisp function deleted.
10895 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10896 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10898 * xterm.h: Update prototype.
10900 2011-05-28 William Xu <william.xwl@gmail.com>
10902 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10903 exiting (Bug#8239).
10905 2011-05-28 Jim Meyering <meyering@redhat.com>
10907 Avoid a sign-extension bug in crypto_hash_function.
10908 * fns.c (to_uchar): Define.
10909 (crypto_hash_function): Use it to convert some newly-signed
10910 variables to unsigned, to avoid sign-extension bugs. For example,
10911 without this change, (md5 "truc") would evaluate to
10912 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10913 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10914 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10916 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10918 Integer overflow fixes.
10920 * dbusbind.c: Serial number integer overflow fixes.
10921 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10922 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10923 to hold a serial number that is too large for a fixnum.
10924 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10925 Check for serial numbers out of range. Decode any serial number
10926 that was so large that it became a float. (Bug#8722)
10928 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10929 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10930 Use XFASTINT rather than XUINT when numbers are nonnegative.
10931 (xd_append_arg, Fdbus_method_return_internal):
10932 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10933 arguments, check that Lisp number is nonnegative, rather than
10934 silently wrapping negative numbers around. (Bug#8722)
10935 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10936 (Bug#8722)
10938 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10940 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10942 ccl: Add integer overflow checks.
10943 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10944 (IN_INT_RANGE): New macros.
10945 (ccl_driver): Use them to check for integer overflow when
10946 decoding a CCL program. Many of the new checks are whether XINT (x)
10947 fits in int; it doesn't always, on 64-bit hosts. The new version
10948 doesn't catch all possible integer overflows, but it's an
10949 improvement. (Bug#8719)
10951 * alloc.c (make_event_array): Use XINT, not XUINT.
10952 There's no need for unsigned here.
10954 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10955 This follows up to the 2011-05-06 change that substituted uintptr_t
10956 for EMACS_INT. This case wasn't caught back then.
10958 Rework Fformat to avoid integer overflow issues.
10959 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10960 now (part of C89). Include <verify.h>.
10961 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10962 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10963 (Fformat): Avoid the prepass trying to compute sizes; it was only
10964 approximate and thus did not catch overflow reliably. Instead, walk
10965 through the format just once, formatting and computing sizes as we go,
10966 checking for integer overflow at every step, and allocating a larger
10967 buffer as needed. Keep track separately whether the format is
10968 multibyte. Keep only the most-recently calculated precision, rather
10969 than them all. Record whether each argument has been converted to
10970 string. Use EMACS_INT, not int, for byte and char and arg counts.
10971 Support field widths and precisions larger than INT_MAX. Avoid
10972 sprintf's undefined behavior with conversion specifications such as %#d
10973 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10974 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10975 formatting out-of-range floating point numbers with int
10976 formats. (Bug#8668)
10978 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10980 * data.c: Avoid integer truncation in expressions involving floats.
10981 * data.c: Include <intprops.h>.
10982 (arith_driver): When there's an integer overflow in an expression
10983 involving floating point, convert the integers to floating point
10984 so that the resulting value does not suffer from catastrophic
10985 integer truncation. For example, on a 64-bit host (* 4
10986 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10987 Do not rely on undefined behavior after integer overflow.
10989 merge count_size_as_multibyte, parse_str_to_multibyte
10990 * character.c, character.h (count_size_as_multibyte):
10991 Rename from parse_str_to_multibyte; all uses changed.
10992 Check for integer overflow.
10993 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10994 since it's now a duplicate of the other. This is more of
10995 a character than a buffer op, so better that it's in character.c.
10996 * fns.c, print.c: Adjust to above changes.
10998 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11000 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11002 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11004 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11005 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11006 (x_clipboard_manager_save): Now static.
11007 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11009 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11010 (crypto_hash_function): Now static.
11011 Fix pointer signedness problems. Avoid unnecessary initializations.
11013 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11015 * termhooks.h (Vselection_alist): Make it terminal-local.
11017 * terminal.c (create_terminal): Initialize it.
11019 * xselect.c: Support for clipboard managers.
11020 (Vselection_alist): Move to termhooks.h as terminal-local var.
11021 (LOCAL_SELECTION): New macro.
11022 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11023 (symbol_to_x_atom): Remove gratuitous arg.
11024 (x_handle_selection_request, lisp_data_to_selection_data)
11025 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11026 (x_own_selection, x_get_local_selection, x_convert_selection):
11027 New arg, specifying work frame. Use terminal-local Vselection_alist.
11028 (some_frame_on_display): Delete unused function.
11029 (Fx_own_selection_internal, Fx_get_selection_internal)
11030 (Fx_disown_selection_internal, Fx_selection_owner_p)
11031 (Fx_selection_exists_p): New optional frame arg.
11032 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11033 (x_handle_selection_clear): Don't treat other terminals with the
11034 same keyboard specially. Use the terminal-local Vselection_alist.
11035 (x_clear_frame_selections): Use Frun_hook_with_args.
11037 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11039 * xterm.h: Add support for those atoms.
11041 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11043 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11044 (converted_selections, conversion_fail_tag): New global variables.
11045 (x_selection_request_lisp_error): Free the above.
11046 (x_get_local_selection): Remove unnecessary code.
11047 (x_reply_selection_request): Args changed; handle arbitrary array
11048 of converted selections stored in converted_selections.
11049 Separate the XChangeProperty and SelectionNotify steps.
11050 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11051 (x_convert_selection): New function.
11052 (x_handle_selection_event): Simplify.
11053 (x_get_foreign_selection): Don't ignore incoming requests while
11054 waiting for an answer; this will fail when we implement
11055 SAVE_TARGETS, and seems unnecessary anyway.
11056 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11057 (Vx_sent_selection_functions): Doc fix.
11059 2011-05-26 Leo Liu <sdl.web@gmail.com>
11061 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11063 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11065 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11067 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11068 for fringe update if it has periodic bitmap.
11069 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11070 and fringe_bitmap_periodic_p.
11072 * fringe.c (get_fringe_bitmap_data): New function.
11073 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11074 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11075 row. Mark glyph row for fringe update if periodicity changed.
11077 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11078 for fringe update unless it has periodic bitmap.
11080 2011-05-25 Kenichi Handa <handa@m17n.org>
11082 * xdisp.c (get_next_display_element): Set correct it->face_id for
11083 a static composition.
11085 2011-05-24 Leo Liu <sdl.web@gmail.com>
11087 * deps.mk (fns.o):
11088 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11090 * fns.c (crypto_hash_function, Fsha1): New function.
11091 (Fmd5): Use crypto_hash_function.
11092 (syms_of_fns): Add Ssha1.
11094 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11096 * gnutls.c: Remove unused macros.
11097 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11098 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11099 Remove macros that are defined and never used.
11100 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11102 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11104 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11105 (Fx_get_selection_internal): Minor cleanup.
11106 (Fx_own_selection_internal): Rename arguments for consistency with
11107 select.el.
11109 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11111 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11113 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11115 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11117 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11119 * dispnew.c (scrolling_window): Don't exclude the case that the
11120 last enabled row in the desired matrix touches the bottom boundary.
11122 2011-05-21 Glenn Morris <rgm@gnu.org>
11124 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11125 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11126 and add some more files.
11128 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11130 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11131 report_file_error introduced by the change from 2011-05-07.
11133 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11135 * systime.h (Time): Define only if emacs is defined.
11136 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11137 where the include path doesn't have X11/X.h by default. See
11138 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11140 2011-05-20 Kenichi Handa <handa@m17n.org>
11142 * composite.c (find_automatic_composition): Fix previous change.
11144 2011-05-20 Glenn Morris <rgm@gnu.org>
11146 * lisp.mk: New file, split from Makefile.in.
11147 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11148 (shortlisp): Remove.
11149 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11151 2011-05-19 Glenn Morris <rgm@gnu.org>
11153 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11154 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11155 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11156 (lisp): Set the order to that of loadup.el.
11157 (shortlisp): Make it a copy of $lisp.
11158 (SOME_MACHINE_LISP): Remove.
11159 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11160 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11162 2011-05-18 Kenichi Handa <handa@m17n.org>
11164 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11165 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11166 (find_automatic_composition): Mostly rewrite for efficiency.
11168 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11170 * makefile.w32-in: Update dependencies.
11172 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11174 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11175 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11177 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11179 Fix some integer overflow issues, such as string length overflow.
11181 * insdel.c (count_size_as_multibyte): Check for string overflow.
11183 * character.c (lisp_string_width): Check for string overflow.
11184 Use EMACS_INT, not int, for string indexes and lengths; in
11185 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11186 the resulting string length overflows an EMACS_INT; instead,
11187 report a string overflow if no precision given. When checking for
11188 precision exhaustion, use a check that cannot possibly have
11189 integer overflow. (Bug#8675)
11190 * character.h (lisp_string_width): Adjust to new signature.
11192 * alloc.c (string_overflow): New function.
11193 (Fmake_string): Use it. This doesn't change behavior, but saves
11194 a few bytes and will simplify future changes.
11195 * character.c (string_escape_byte8): Likewise.
11196 * lisp.h (string_overflow): New decl.
11198 Fixups, following up to the user-interface timestamp change.
11199 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11200 for UI timestamps, instead of unsigned long.
11201 * msdos.c (mouse_get_pos): Likewise.
11202 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11203 * w32gui.h (Time): Define by including "systime.h" rather than by
11204 declaring it ourselves. (Bug#8664)
11206 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11207 * image.c (clear_image_cache): Likewise.
11209 * term.c (term_mouse_position): Don't assume time_t wraparound.
11211 Be more systematic about user-interface timestamps.
11212 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11213 and sometimes 'EMACS_UINT', to represent these timestamps.
11214 This change causes it to use 'Time' uniformly, as that's what X uses.
11215 This makes the code easier to follow, and makes it easier to catch
11216 integer overflow bugs such as Bug#8664.
11217 * frame.c (Fmouse_position, Fmouse_pixel_position):
11218 Use Time, not unsigned long, for user-interface timestamps.
11219 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11220 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11221 * keyboard.h (last_event_timestamp): Likewise.
11222 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11223 * menu.h (xmenu_show): Likewise.
11224 * term.c (term_mouse_position): Likewise.
11225 * termhooks.h (struct input_event.timestamp): Likewise.
11226 (struct terminal.mouse_position_hook): Likewise.
11227 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11228 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11229 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11230 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11231 what it was before.
11232 * menu.h, termhooks.h: Include "systime.h", for Time.
11234 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11235 Don't assume that the difference between two unsigned long values
11236 can fit into an integer. At this point, we know button_down_time
11237 <= event->timestamp, so the difference must be nonnegative, so
11238 there's no need to cast the result if double-click-time is
11239 nonnegative, as it should be; check that it's nonnegative, just in
11240 case. This bug is triggered when events are more than 2**31 ms
11241 apart (about 25 days). (Bug#8664)
11243 * xselect.c (last_event_timestamp): Remove duplicate decl.
11244 (x_own_selection): Remove needless cast to unsigned long.
11246 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11247 that always fit in int. Use a sentinel instead of a counter, to
11248 avoid a temp and to allay GCC's concerns about possible int overflow.
11249 * frame.h (struct frame): Use int for menu_bar_items_used
11250 instead of EMACS_INT, since it always fits in int.
11252 * menu.c (grow_menu_items): Check for int overflow.
11254 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11256 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11257 Before, the code was not consistent. These values cannot exceed
11258 2**31 - 1 so there's no need to make them unsigned.
11259 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11260 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11261 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11262 as modifiers.
11263 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11265 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11266 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11267 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11268 presumably because the widths might not match.
11270 * window.c (size_window): Avoid needless test at loop start.
11272 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11274 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11276 2011-05-12 Drew Adams <drew.adams@oracle.com>
11278 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11280 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11282 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11283 `width' to `bar_area_x' and `bar_area_width', respectively.
11284 (x_scroll_run): Take account of fringe background extension.
11286 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11287 Rename local vars `left' and `width' to `bar_area_x' and
11288 `bar_area_width', respectively.
11289 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11290 background extension.
11292 2011-05-10 Jim Meyering <meyering@redhat.com>
11294 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11296 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11298 * image.c (Finit_image_library): Return t for built-in image types,
11299 like pbm and xbm. (Bug#8640)
11301 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11303 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11305 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11307 * w32console.c (Fset_screen_color): Doc fix.
11308 (Fget_screen_color): New function.
11309 (syms_of_ntterm): Defsubr it.
11311 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11312 unlink the temporary file if Fcall_process didn't create it in the
11313 first place.
11314 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11315 child process will be redirected to a file specified with `:file'.
11316 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11317 cue to call_process_cleanup not to close that handle.
11319 2011-05-07 Ben Key <bkey76@gmail.com>
11321 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11322 one of two shell specific rules, either bootstrap-temacs-CMD or
11323 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11324 to the previous implementation of the bootstrap-temacs rule.
11325 The bootstrap-temacs-CMD rule is similar to the previous
11326 implementation of the bootstrap-temacs rule except that it
11327 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11328 variable.
11330 These changes, along with some changes to nt/configure.bat,
11331 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11332 earlier fix to add support for --cflags and --ldflags options
11333 that include quotes so that it works whether make uses cmd or
11334 sh as the shell.
11336 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11338 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11339 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11340 is a constant.
11341 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11342 a string. Handle both cases.
11343 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11344 (Fdbus_register_method): Use Qinvalid_function.
11346 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11348 * makefile.w32-in: Update dependencies.
11349 (LISP_H): Add inttypes.h and stdin.h.
11350 (PROCESS_H): Add unistd.h.
11352 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11354 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11355 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11357 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11359 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11361 * term.c (vfatal): Remove stray call to va_end.
11362 It's not needed and the C Standard doesn't allow it here anyway.
11364 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11365 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11367 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11368 bytes.
11370 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11372 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11374 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11376 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11378 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11380 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11381 * charset.c (Fdefine_charset_internal): Don't initialize
11382 charset.code_space[15]. The value was garbage, on hosts with
11383 32-bit int (Bug#8600).
11385 * lread.c (read_integer): Be more consistent with string-to-number.
11386 Use string_to_number to do the actual conversion; this avoids
11387 rounding errors and fixes some other screwups. Without this fix,
11388 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11389 (digit_to_number): Move earlier, for benefit of read_integer.
11390 Return -1 if the digit is out of range for the base, -2 if it is
11391 not a digit in any supported base. (Bug#8602)
11393 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11395 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11396 to match comment at start of function. This also removes a
11397 GCC warning about overflow in a 32+64-bit port.
11399 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11401 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11402 Reported by Stefan Monnier in
11403 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11404 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11405 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11407 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11408 (EMACS_UINTPTR): Likewise, with uintptr_t.
11410 * lisp.h: Prefer 64-bit EMACS_INT if available.
11411 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11412 on 32-bit hosts that have 64-bit int, so that they can access
11413 large files.
11414 However, temporarily disable this change unless the temporary
11415 symbol WIDE_EMACS_INT is defined.
11417 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11419 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11420 This removes an assumption that EMACS_INT and long are the same
11421 width as pointers. The assumption is true for Emacs porting targets
11422 now, but we want to make other targets possible.
11423 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11424 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11425 In the rest of the code, change types of integers that hold casted
11426 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11427 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11428 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11429 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11430 No need to cast type when ORing.
11431 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11432 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11433 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11434 assume EMACS_INT is the same width as char *.
11435 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11436 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11437 Remove no-longer-needed casts.
11438 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11439 (xg_tool_bar_help_callback, xg_make_tool_item):
11440 Use EMACS_INTPTR to hold an integer
11441 that will be cast to void *; this can avoid a GCC warning
11442 if EMACS_INT is not the same width as void *.
11443 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11444 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11445 (current_message_1, set_message_1):
11446 Use a local to convert to proper width without a cast.
11447 * xmenu.c (dialog_selection_callback): Likewise.
11449 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11450 Also, don't assume VALBITS / RAND_BITS is less than 5,
11451 and don't rely on undefined behavior when shifting a 1 left into
11452 the sign bit.
11453 * lisp.h (get_random): Change signature to match.
11455 * lread.c (hash_string): Use size_t, not int, for hash computation.
11456 Normally we prefer signed values; but hashing is special, because
11457 it's better to use unsigned division on hash table sizes so that
11458 the remainder is nonnegative. Also, size_t is the natural width
11459 for hashing into memory. The previous code used 'int', which doesn't
11460 retain enough info to hash well into very large tables.
11461 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11463 * dbusbind.c: Don't possibly lose pointer info when converting.
11464 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11465 Use XPNTR rather than XHASH, so that the high-order bits of
11466 the pointer aren't lost when converting through void *.
11468 * eval.c (Fautoload): Don't double-shift a pointer.
11470 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11472 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11474 * gnutls.c (DEF_GNUTLS_FN):
11475 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11477 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11479 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11480 marker. (Bug#8610)
11482 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11484 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11485 New version that can reserve upto 2GB of heap space.
11487 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11489 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11491 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11493 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11494 `gnutls_certificate_set_x509_key_file'.
11496 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11498 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11499 Update dependencies.
11501 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11503 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11504 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11505 Remove unused parameter `fildes'.
11506 * process.c (read_process_output, send_process): Don't pass it.
11508 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11510 Fix previous change: the library cache is defined in w32.c.
11511 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11512 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11514 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11516 Implement dynamic loading of GnuTLS on Windows.
11518 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11519 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11520 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11521 Declare.
11523 * gnutls.c (Qgnutls_dll): Define.

11553 * process.c: Include lisp.h before w32.h, not after.
11554 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11555 instead of gnutls_record_check_pending.
11557 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11559 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11561 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11562 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11563 as passed in.
11565 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11567 * xterm.c (x_set_frame_alpha): Do not set property on anything
11568 else than FRAME_X_OUTER_WINDOW (Bug#8608).

11572 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11574 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11576 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

11598 interruptions.
11600 * callproc.c (Fcall_process): Add (:file "file") as an option for
11601 the STDOUT buffer.
11602 (Fcall_process_region): Ditto.
11604 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11606 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11607 rather than `XVECTOR (FOO)->size'.
11609 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11610 inttypes.h, as a gnulib replacement is used if it not available in
11611 system headers.
11613 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11615 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11616 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11617 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11619 * coding.c (coding_alloc_by_realloc): Error out if destination
11620 will grow beyond MOST_POSITIVE_FIXNUM.
11621 (decode_coding_emacs_mule): Abort if there isn't enough place in
11622 charbuf for the composition carryover bytes. Reserve an extra
11623 space for up to 2 characters produced in a loop.
11624 (decode_coding_iso_2022): Abort if there isn't enough place in
11625 charbuf for the composition carryover bytes.
11627 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11629 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11630 aborting when %lld or %lll format is passed.
11631 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11632 %llo or %llx format is passed. (Bug#8545)
11634 * window.c (window_scroll_line_based): Use a marker instead of
11635 simple variables to record original value of point. (Bug#7952)
11637 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11638 produced by %s or %c overflows available buffer space. (Bug#8545)
11640 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11642 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11643 (SIZE_MAX): Move defn after all includes, as they might #define it.
11645 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11647 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11649 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11651 * keyboard.c (Qdelayed_warnings_hook): Define.
11652 (command_loop_1): Run `delayed-warnings-hook'
11653 if Vdelayed_warnings_list is non-nil.
11654 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11655 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11657 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11659 * doprnt.c (doprnt): Don't return value smaller than the buffer
11660 size if the message was truncated. (Bug#8545).
11662 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11664 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11665 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11667 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11669 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11671 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11673 * makefile.w32-in: Update dependencies.
11675 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11677 Improve `doprnt' and its usage. (Bug#8545)
11678 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11679 `format_end'. Remove support for %l as a conversion specifier.
11680 Don't use xrealloc. Improve diagnostics when the %l size modifier
11681 is used. Update the commentary.
11683 * eval.c (verror): Simplify calculation of size_t.
11685 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11686 messages.
11688 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11690 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11691 change.
11693 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11695 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11696 This makes this file independent of the recent pseudovector change.
11698 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11700 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11702 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11703 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11704 Remove unused local.
11705 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11707 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11708 GCC 4.6.0 optimizes based on type-based alias analysis.
11709 For example, if b is of type struct buffer * and v of type struct
11710 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11711 != &v->size, and therefore "v->size = 1; b->size = 2; return
11712 v->size;" must therefore return 1. This assumption is incorrect
11713 for Emacs, since it type-puns struct Lisp_Vector * with many other
11714 types. To fix this problem, this patch adds a new type struct
11715 vectorlike_header that documents the constraints on layout of vectors
11716 and pseudovectors, and helps optimizing compilers not get fooled
11717 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11718 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11719 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11720 the size member.
11721 (XSETPVECTYPE): Rewrite in terms of new macro.
11722 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11723 This is a bit clearer, and further avoids the possibility of
11724 undesirable aliasing.
11725 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11726 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11727 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11728 since Lisp_Subr is a special case (no "next" field).
11729 (ASIZE): Now uses header.size rather than size.
11730 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11731 to avoid the hassle of writing XVECTOR (foo)->header.size.
11732 (struct vectorlike_header): New type.
11733 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11734 object, to help avoid aliasing.
11735 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11736 (SUBRP): Likewise, since Lisp_Subr is a special case.
11737 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11738 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11739 (struct Lisp_Hash_Table): Combine first two members into a single
11740 struct vectorlike_header member. All uses of "size" and "next" members
11741 changed to be "header.size" and "header.next".
11742 * buffer.h (struct buffer): Likewise.
11743 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11744 * frame.h (struct frame): Likewise.
11745 * process.h (struct Lisp_Process): Likewise.
11746 * termhooks.h (struct terminal): Likewise.
11747 * window.c (struct save_window_data, struct saved_window): Likewise.
11748 * window.h (struct window): Likewise.
11749 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11750 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11751 * buffer.c (init_buffer_once): Likewise.
11752 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11753 special case.
11754 * process.c (Fformat_network_address): Use local var for size,
11755 for brevity.
11757 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11759 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11760 * data.c (atof): Remove decl; no longer used or needed.
11761 (digit_to_number): Move to lread.c.
11762 (Fstring_to_number): Use new string_to_number function, to be
11763 consistent with how the Lisp reader treats infinities and NaNs.
11764 Do not assume that floating-point numbers represent EMACS_INT
11765 without losing information; this is not true on most 64-bit hosts.
11766 Avoid double-rounding errors, by insisting on integers when
11767 parsing non-base-10 numbers, as the documentation specifies.
11768 * lisp.h (string_to_number): New decl, replacing ...
11769 (isfloat_string): Remove.
11770 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11771 (read1): Do not accept +. and -. as integers; this
11772 appears to have been a coding error. Similarly, do not accept
11773 strings like +-1e0 as floating point numbers. Do not report
11774 overflow for integer overflows unless the base is not 10 which
11775 means we have no simple and reliable way to continue.
11776 Break out the floating-point parsing into a new
11777 function string_to_number, so that Fstring_to_number parses
11778 floating point numbers consistently with the Lisp reader.
11779 (digit_to_number): Move here from data.c. Make it static inline.
11780 (E_CHAR, EXP_INT): Remove, replacing with ...
11781 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11782 (string_to_number): New function, replacing isfloat_string.
11783 This function checks for valid syntax and produces the resulting
11784 Lisp float number too. Rework it so that string-to-number
11785 no longer mishandles examples like "1.0e+". Use strtoumax,
11786 so that overflow for non-base-10 numbers is reported only when
11787 there's no portable and simple way to convert to floating point.
11789 * textprop.c (set_text_properties_1): Rewrite for clarity,
11790 and to avoid GCC warning about integer overflow.
11792 * intervals.h (struct interval): Use EMACS_INT for members
11793 where EMACS_UINT might cause problems. See
11794 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11795 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11796 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11797 All uses changed.
11798 (offset_intervals): Tell GCC not to worry about length overflow
11799 when negating a negative length.
11801 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11802 (overrun_check_free): Likewise.
11804 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11805 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11806 word size.
11808 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11809 (gnutls_make_error): Rename local to avoid shadowing.
11810 (gnutls_emacs_global_deinit): ifdef out; not used.
11811 (Fgnutls_boot): Use const for pointer to readonly storage.
11812 Comment out unused local. Fix pointer signedness problems.
11814 * lread.c (openp): Don't stuff size_t into an 'int'.
11815 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11816 about possible signed overflow.
11818 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11819 (GDK_KEY_g): Don't define if already defined.
11820 (xg_prepare_tooltip): Avoid pointer signedness problem.
11821 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11823 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11824 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11826 * xfns.c (Fx_window_property): Simplify a bit,
11827 to make a bit faster and to avoid GCC 4.6.0 warning.
11828 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11830 * fns.c (internal_equal): Don't assume size_t fits in int.
11832 * alloc.c (compact_small_strings): Tighten assertion a little.
11834 Replace pEd with more-general pI, and fix some printf arg casts.
11835 * lisp.h (pI): New macro, generalizing old pEd macro to other
11836 conversion specifiers. For example, use "...%"pI"d..." rather
11837 than "...%"pEd"...".
11838 (pEd): Remove. All uses replaced with similar uses of pI.
11839 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11840 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11841 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11842 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11843 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11844 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11845 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11846 64-bit hosts.
11847 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11848 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11849 * print.c (safe_debug_print, print_object): Likewise.
11850 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11851 to int.
11852 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11853 avoiding the 0 flag, which is not portable.
11854 * process.c (Fmake_network_process): Use pI to avoid cast.
11855 * region-cache.c (pp_cache): Likewise.
11856 * xdisp.c (decode_mode_spec): Likewise.
11857 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11858 behavior on 64-bit hosts with printf arg.
11859 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11860 (x_stop_queuing_selection_requests): Likewise.
11861 (x_get_window_property): Don't truncate byte count to an 'int'
11862 when tracing.
11864 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11865 here, since it parses constructs like leading '-' and spaces,
11866 which are not wanted; and it overflows with large numbers.
11867 Instead, simply match F[0-9]+, which is what is wanted anyway.
11869 * alloc.c: Remove unportable assumptions about struct layout.
11870 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11871 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11872 (allocate_vectorlike, make_pure_vector): Use the new macros,
11873 plus offsetof, to remove unportable assumptions about struct layout.
11874 These assumptions hold on all porting targets that I know of, but
11875 they are not guaranteed, they're easy to remove, and removing them
11876 makes further changes easier.
11878 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11879 This doesn't fix a bug but makes the code clearer.
11880 (string_overrun_cookie): Now const. Use initializers that
11881 don't formally overflow signed char, to avoid warnings.
11882 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11883 can cause Emacs to crash when string overrun checking is enabled.
11884 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11885 multiple of sizeof (EMACS_INT); it need not be, if
11886 alignof(EMACS_INT) < sizeof (EMACS_INT).
11887 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11889 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11891 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11893 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11895 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11896 supposed to be handshaking. (Bug#8556)
11897 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11899 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11901 * lisp.h (Qdebug): List symbol.
11902 * eval.c (Qdebug): Restore global linkage.
11903 * keyboard.c (debug-on-event): New variable.
11904 (handle_user_signal): Break into debugger when debug-on-event
11905 matches the current signal symbol.
11907 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11909 * alloc.c (check_sblock, check_string_bytes)
11910 (check_string_free_list): Convert to standard C.
11912 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11914 * w32.c (emacs_gnutls_push): Fix typo.
11916 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11918 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11919 "cast to pointer from integer of different size".
11921 Improve doprnt and its use in verror. (Bug#8545)
11922 * doprnt.c (doprnt): Document the set of format control sequences
11923 supported by the function. Use SAFE_ALLOCA instead of always
11924 using `alloca'.
11926 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11927 is one byte too soon. Don't use xrealloc; instead xfree and
11928 xmalloc anew.
11930 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11932 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11933 callbacks stage.

12661 DEFUN now defines a static function. To make the function external
12662 so that it can be used in other C modules, use the new macro DEFUE.

12740 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12741 since callers should never pass a negative size.

12746 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12748 * xdisp.c (redisplay_window): Don't try to determine the character
12749 position of the scroll margin if the window start point w->startp
12750 is outside the buffer's accessible region. (Bug#8468)
12752 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12754 Fix write-region and its subroutines for buffers > 2GB.
12755 * fileio.c (a_write, e_write): Modify declaration of arguments and
12756 local variables to support buffers larger than 2GB.
12757 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12759 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12760 argument, local variables, and return value.
12762 * lisp.h: Update prototypes of emacs_write and emacs_read.

12766 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12768 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

12772 * xdisp.c (vmessage): Use a better test for character truncation.
12774 * charset.c (load_charset_map): <, not <=, for optimization,

12784 * callint.c (Fcall_interactively): <, not <=, for optimization.
12785 (Fcall_interactively): Count the number of arguments produced,
12786 not the number of arguments given. This is simpler and lets GCC
12787 4.6.0 generate slightly better code.
12789 * ftfont.c: Distingish more carefully between FcChar8 and char.
12790 The previous code passed unsigned char * to a functions like
12791 strlen and xstrcasecmp that expect char *, which does not
12792 conform to the C standard.
12793 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12794 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12795 char * when the C standard requires it.
12797 * keyboard.c (read_char): Remove unused var.
12799 * eval.c: Port to Windows vsnprintf (Bug#8435).
12800 Include <limits.h>.
12801 (SIZE_MAX): Define if the headers do not.
12802 (verror): Do not give up if vsnprintf returns a negative count.
12803 Instead, grow the buffer. This ports to Windows vsnprintf, which
12804 does not conform to C99. Problem reported by Eli Zaretskii.
12805 Also, simplify the allocation scheme, by avoiding the need for
12806 calling realloc, and removing the ALLOCATED variable.
12808 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12810 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12811 But keep the doprint source code for now, as we might revamp it
12812 and use it again (Bug#8435).
12813 * lisp.h (doprnt): Remove.
12814 * Makefile.in (base_obj): Remove doprnt.o.
12815 * deps.mk (doprnt.o): Remove.
12817 error: Print 32- and 64-bit integers portably (Bug#8435).
12818 Without this change, on typical 64-bit hosts error ("...%d...", N)
12819 was used to print both 32- and 64-bit integers N, which relied on
12820 undefined behavior.
12821 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12822 * lisp.h (error, verror): Mark as printf-like functions.
12823 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12824 Report overflow in size calculations when allocating printf buffer.
12825 Do not truncate output string at its first null byte.
12826 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12827 Truncate the output at a character boundary, since vsnprintf does not
12828 do that.
12829 * charset.c (check_iso_charset_parameter): Convert internal
12830 character to string before calling 'error', since %c now has the
12831 printf meaning.
12832 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12833 overflow when computing char to be passed to 'error'. Do not
12834 pass Lisp_Object to 'error'; pass the integer instead.
12835 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12836 formatted with plain %d.
12838 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12840 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12842 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12844 * xterm.c (x_catch_errors): Remove duplicate declaration.
12846 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12848 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12850 2011-04-10 Jim Meyering <meyering@redhat.com>
12852 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12853 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12854 return ssize_t not "int", and use size_t as the buffer length.
12855 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12856 * gnutls.h: Update declarations.
12857 * process.c (read_process_output): Use ssize_t, to match.
12858 (send_process): Likewise.
12860 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12862 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12864 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12866 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12867 Use unsigned char, to match FcChar8 type definition.
12869 * xterm.c (handle_one_xevent):
12870 * xmenu.c (create_and_show_popup_menu):
12871 * xselect.c (x_decline_selection_request)
12872 (x_reply_selection_request): Avoid type-punned deref of X events.
12874 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12876 Fix some uses of `int' instead of EMACS_INT.
12877 * search.c (string_match_1, fast_string_match)
12878 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12879 (scan_buffer, find_next_newline_no_quit)
12880 (find_before_next_newline, search_command, Freplace_match)
12881 (Fmatch_data): Make some `int' variables be EMACS_INT.
12883 * xdisp.c (display_count_lines): 3rd argument and return value now
12884 EMACS_INT. All callers changed.
12885 (pint2hrstr): Last argument is now EMACS_INT.
12887 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12888 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12889 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12890 (decode_coding_utf_16, decode_coding_emacs_mule)

12899 (encode_designation_at_bol, encode_coding_iso_2022)
12900 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12901 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12902 Declare EMACS_INT.
12903 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12904 (encode_invocation_designation): Last argument P_NCHARS is now
12905 EMACS_INT.
12906 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12907 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12909 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12910 All users changed.
12912 * ccl.c (Fccl_execute_on_string): Declare some variables
12913 EMACS_INT.
12915 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12917 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

12925 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12927 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12929 * keyboard.c (read_char): Call Lisp function help-form-show,
12930 instead of using internal_with_output_to_temp_buffer.
12931 (Qhelp_form_show): New var.
12932 (syms_of_keyboard): Use DEFSYM macro.
12934 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12936 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12938 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

12947 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12949 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12951 Fix more problems found by GCC 4.6.0's static checks.

12968 to system-supplied API.
12970 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12972 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12973 This avoids several warnings with gcc -Wstrict-overflow.
12974 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12975 directly, rather than having caller test rule sign. This avoids
12976 some unnecessary tests.
12977 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12978 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12979 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12981 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12982 (xfont_open): Avoid unnecessary tests.
12984 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12986 * composite.h, composite.c (composition_gstring_put_cache):
12987 Use EMACS_INT, not int, for length.
12989 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12990 breaking out part of COMPOSITION_DECODE_RULE.
12991 (COMPOSITION_DECODE_RULE): Use it.
12992 * composite.c (get_composition_id): Remove unused local vars,
12993 by using the new macro.
12995 * textprop.c (set_text_properties_1): Change while to do-while,
12996 since the condition is always true at first.
12998 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12999 (interval_deletion_adjustment): Return unsigned value.
13000 All uses changed.

13003 (exec_sentinel): Remove vars that were set but not used.
13004 (create_pty): Remove unnecessary "volatile"s.

13016 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13018 * print.c (print_error_message): Avoid int overflow.
13020 * font.c (font_list_entities): Redo for clarity,
13021 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13023 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13024 (font_score): Avoid potential overflow in diff calculation.
13026 * fns.c (substring_both): Remove var that is set but not used.
13027 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13029 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13031 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13032 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13033 can always succeed if overflow has undefined behavior.
13035 * search.c (boyer_moore, wordify): Remove vars set but not used.
13036 (wordify): Omit three unnecessary tests.
13038 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13043 * dired.c (file_name_completion): Remove var that is set but not used.
13045 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13047 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13048 (Finsert_file_contents): Remove unnecessary code checking fd.
13050 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13051 Check for integer overflow on size calculations.
13053 * buffer.c (Fprevious_overlay_change): Remove var that is set
13054 but not used.
13056 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13057 Remove vars that are set but not used.
13058 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13059 (timer_check_2): Mark vars as initialized.
13061 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13063 * image.c (lookup_image): Remove var that is set but not used.
13064 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13066 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13067 that are set but not used.
13069 * xfns.c (make_invisible_cursor): Don't return garbage
13070 if XCreateBitmapFromData fails (Bug#8410).
13072 * xselect.c (x_get_local_selection, x_handle_property_notify):
13073 Remove vars that are set but not used.
13075 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13076 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13078 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13079 Remove var that is set but not used.
13080 (scroll_bar_windows_size): Now size_t, not int.
13081 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13082 Check for overflow.
13084 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13085 (map_tty_color) [!defined MSDOS]: Likewise.
13087 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13089 * coding.c: Remove vars that are set but not used.
13090 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13091 All callers changed.
13092 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13093 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13094 (decode_coding_charset): Remove vars that are set but not used.
13096 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13097 that is set but not used.
13099 * print.c (print_object): Remove var that is set but not used.
13101 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13102 The gnulib version avoids calling malloc in the usual case,
13103 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13104 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13105 * filelock.c (current_lock_owner): Likewise.
13106 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13107 * sysdep.c: Include allocator.h, careadlinkat.h.
13108 (emacs_no_realloc_allocator): New static constant.
13109 (emacs_readlink): New function.
13110 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13111 ../lib/careadlinkat.h.
13113 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13115 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13116 first non-nil return value).
13118 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13120 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13121 if not defined (Bug#8403).
13123 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13125 * xdisp.c (display_count_lines): Remove parameter `start',

13130 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13131 and thereabouts. All callers changed.
13132 (get_per_char_metric): Remove parameter `f', unused since
13133 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13135 2011-04-02 Jim Meyering <meyering@redhat.com>
13137 do not dereference NULL upon failed strdup
13138 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13139 (ns_get_family): Likewise.
13141 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13143 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13145 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13147 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13148 later (Bug#8403).
13150 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13152 Add lexical binding.
13154 * window.c (Ftemp_output_buffer_show): New fun.
13155 (Fsave_window_excursion):
13156 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13158 * lread.c (lisp_file_lexically_bound_p): New function.

13163 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13164 Mark as dynamic.
13165 (syms_of_lread): Declare `lexical-binding'.
13167 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13169 * keyboard.c (eval_dyn): New fun.
13170 (menu_item_eval_property): Use it.
13172 * image.c (parse_image_spec): Use Ffunctionp.
13174 * fns.c (concat, mapcar1): Accept byte-code-functions.
13176 * eval.c (Fsetq): Handle lexical vars.
13177 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13178 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13179 (FletX, Flet): Obey lexical binding.
13180 (Fcommandp): Handle closures.
13181 (Feval): New `lexical' arg.
13182 (eval_sub): New function extracted from Feval. Use it almost
13183 everywhere where Feval was used. Look up vars in lexical env.
13184 Handle closures.
13185 (Ffunctionp): Move from subr.el.
13186 (Ffuncall): Handle closures.
13187 (apply_lambda): Remove `eval_flags'.
13188 (funcall_lambda): Handle closures and new byte-code-functions.
13189 (Fspecial_variable_p): New function.
13190 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13191 but without exporting it to Lisp.
13193 * doc.c (Fdocumentation, store_function_docstring):
13194 * data.c (Finteractive_form): Handle closures.
13196 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13197 interactive spec.
13199 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13200 New byte-codes.
13201 (exec_byte_code): New function extracted from Fbyte_code to handle new
13202 calling convention for byte-code-functions. Add new byte-codes.
13204 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13206 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13208 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13210 * xdisp.c (redisplay_internal): Fix prototype.
13212 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13214 * xdisp.c (SCROLL_LIMIT): New macro.
13215 (try_scrolling): Use it when setting scroll_limit.
13216 Limit scrolling to 100 screen lines.
13217 (redisplay_window): Even when falling back on "recentering",
13218 position point in the window according to scroll-conservatively,
13219 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13221 (try_scrolling): When point is above the window, allow searching
13222 as far as scroll_max, or one screenful, to compute vertical
13223 distance from PT to the scroll margin position. This prevents
13224 try_scrolling from unnecessarily failing when
13225 scroll-conservatively is set to a value slightly larger than the
13226 window height. Clean up the case of PT below the margin at bottom
13227 of window: scroll_max can no longer be INT_MAX. When aggressive
13228 scrolling is in use, don't let point enter the opposite scroll
13229 margin as result of the scroll.
13230 (syms_of_xdisp) <scroll-conservatively>: Document the
13231 threshold of 100 lines for never-recentering scrolling.
13233 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13235 * dispextern.h (move_it_by_lines):
13236 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13237 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13238 (message_log_check_duplicate): Remove parameters `prev_bol' and
13239 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13240 (redisplay_internal): Remove parameter `preserve_echo_area',
13241 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13243 * indent.c (Fvertical_motion):
13244 * window.c (window_scroll_pixel_based, Frecenter):
13245 Don't pass `need_y_p' to `move_it_by_lines'.
13247 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13249 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13250 steal a few bits to be more compact.
13251 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13252 Remove unneeded casts.
13254 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13256 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13258 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13259 binding" message (bug#7967).
13261 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13263 Fix more problems found by GCC 4.6.0's static checks.
13265 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13266 Remove unused local var.
13268 * editfns.c (Fmessage_box): Remove unused local var.
13270 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13271 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13272 Omit unused local vars.
13273 * window.c (shrink_windows): Omit unused local var.
13274 * menu.c (digest_single_submenu): Omit unused local var.
13275 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13276 Omit unused local var.
13278 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13279 Don't assume string length fits in int.
13280 (keyremap_step, read_key_sequence): Use size_t for sizes.
13281 (read_key_sequence): Don't check last_real_key_start redundantly.
13283 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13284 instead of alloca (Bug#8344).
13286 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13287 (Fbacktrace_frame): Don't assume nframes fits in int.
13289 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13291 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13292 concerns.

13296 * cm.c (calccost): Turn while-do into do-while, for clarity.
13298 * keyboard.c (syms_of_keyboard): Use the same style as later
13299 in this function when indexing through an array. This also
13300 works around GCC bug 48267.
13302 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13304 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

13307 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13309 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13310 This avoids undefined behavior on integer overflow, and is a bit
13311 more convenient anyway since it is compared to a size_t variable.
13313 Variadic C functions now count arguments with size_t, not int.
13314 This avoids an unnecessary limitation on 64-bit machines, which
13315 caused (substring ...) to crash on large vectors (Bug#8344).
13316 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13317 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13318 All variadic functions and their callers changed accordingly.
13319 (struct gcpro.nvars): Now size_t, not int. All uses changed.

13323 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13324 (funcall_lambda, mark_backtrace): Likewise.
13325 * fns.c (concat): Likewise.
13326 * frame.c (x_set_frame_parameters): Likewise.
13327 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13328 0 if not found, not -1. All callers changed.
13330 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13331 (stack_copy_size): Now size_t, not int.
13332 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13334 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13336 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13337 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13338 All callers changed.
13340 * lisp.h (multibyte_char_to_unibyte):
13341 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13342 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13343 * character.h (CHAR_TO_BYTE8):
13344 * cmds.c (internal_self_insert):
13345 * editfns.c (general_insert_function):
13346 * keymap.c (push_key_description):
13347 * search.c (Freplace_match):
13348 * xdisp.c (message_dolog, set_message_1): All callers changed.
13350 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13352 * keyboard.c (safe_run_hook_funcall): New function.
13353 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13354 don't set the hook to nil, but remove the offending function instead.
13355 (Qcommand_hook_internal): Remove, unused.
13356 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13357 Vcommand_hook_internal.
13359 * eval.c (enum run_hooks_condition): Remove.
13360 (funcall_nil, funcall_not): New functions.
13361 (run_hook_with_args): Call each function through a `funcall' argument.
13362 Remove `cond' argument, now redundant.
13363 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13364 (Frun_hook_with_args_until_failure): Adjust accordingly.
13365 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13367 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13369 * dispextern.h (string_buffer_position): Remove declaration.
13371 * print.c (strout): Remove parameter `multibyte', unused since
13372 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13374 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13375 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13376 All callers changed.
13378 * w32.c (_wsa_errlist): Use braces for struct initializers.

13381 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13382 All callers changed.

13384 used outside xdisp.c).
13385 (cursor_row_p): Remove parameter `w', unused since
13386 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

13388 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13389 All callers changed.
13391 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13393 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13404 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
13406 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

13413 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
13414 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
13415 Replace SIGTYPE with void everywhere.

13422 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13424 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13426 * w32.c (read_unc_volume): Use parameter `henum', instead of
13427 global variable `wget_enum_handle'.
13429 * keymap.c (describe_vector): Remove parameters `indices' and
13430 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

13441 * w32menu.c (w32_menu_display_help):
13442 * xmenu.c (show_help_event, menu_help_callback):
13443 Adjust calls to `show_help_echo'.
13445 * gtkutil.c (xg_maybe_add_timer):
13446 * keyboard.c (readable_events):
13447 * process.c (wait_reading_process_output):
13448 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
13450 * insdel.c (adjust_markers_gap_motion):
13451 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

13525 2011-03-23 Julien Danjou <julien@danjou.info>
13527 * term.c (Fsuspend_tty, Fresume_tty):
13528 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13529 * window.c (temp_output_buffer_show):
13530 * insdel.c (signal_before_change):
13531 * frame.c (Fhandle_switch_frame):
13532 * fileio.c (Fdo_auto_save):
13533 * emacs.c (Fkill_emacs):
13534 * editfns.c (save_excursion_restore):
13535 * cmds.c (internal_self_insert):
13536 * callint.c (Fcall_interactively):
13537 * buffer.c (Fkill_all_local_variables):
13538 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13539 Use Frun_hooks.
13540 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13541 unconditionally since it does the check itself.
13543 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13545 Fix more problems found by GCC 4.5.2's static checks.
13547 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13548 the first time through the loop, since we know p0 < p1 then.
13549 This also avoids a gcc -Wstrict-overflow warning.
13551 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13552 leading to a memory leak, possible in functions like
13553 load_charset_map_from_file that can allocate an unbounded number
13554 of objects (Bug#8318).
13556 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13557 that could (at least in theory) be that large.
13559 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13560 This is less likely to overflow, and avoids undefined behavior if
13561 overflow does occur. All callers changed. Use strtoul to scan
13562 for the unsigned long integer.
13563 (pint2hrstr): Simplify and tune code slightly.
13564 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13567 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13569 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13570 This also avoids a warning with gcc -Wstrict-overflow.

13572 This also avoids a warning with gcc -Wstrict-overflow.
13574 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13575 fail (Bug#8306).
13577 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13579 * process.c (Fmake_network_process): Use socklen_t, not int,
13580 where POSIX says socklen_t is required in portable programs.
13581 This fixes a porting bug on hosts like 64-bit HP-UX, where
13582 socklen_t is wider than int (Bug#8277).
13583 (Fmake_network_process, server_accept_connection):
13584 (wait_reading_process_output, read_process_output):
13585 Likewise.
13587 * process.c: Rename or move locals to avoid shadowing.
13588 (list_processes_1, Fmake_network_process):
13589 (read_process_output_error_handler, exec_sentinel_error_handler):
13590 Rename or move locals.
13591 (Fmake_network_process): Define label "retry_connect" only if needed.
13592 (Fnetwork_interface_info): Fix pointer signedness.
13593 (process_send_signal): Add cast to avoid pointer signedness problem.
13594 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13595 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13597 Make tparam.h and terminfo.c consistent.
13598 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13599 Include tparam.h instead, since it declares them.
13600 * cm.h (PC): Remove extern decl; tparam.h now does this.
13601 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13602 * terminfo.c: Include tparam.h, to check interfaces.
13603 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13604 (tparam): Adjust signature to match interface in tparam.h;
13605 this removes some undefined behavior. Check that outstring and len
13606 are zero, which they always are with Emacs.
13607 * tparam.h (PC, BC, UP): New extern decls.
13609 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13610 (xftfont_open): Rename locals to avoid shadowing.
13612 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13613 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13614 (OTF_TAG_SYM): Omit macro if not needed.
13615 (ftfont_list): Remove unused local.
13616 (get_adstyle_property, ftfont_pattern_entity):
13617 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13618 Rename locals to avoid shadowing.
13620 * xfont.c (xfont_list_family): Mark var as initialized.
13622 * xml.c (make_dom): Now static.
13624 * composite.c (composition_compute_stop_pos): Rename local to
13625 avoid shadowing.
13626 (composition_reseat_it): Remove unused locals.
13627 (find_automatic_composition, composition_adjust_point): Likewise.
13628 (composition_update_it): Mark var as initialized.
13629 (find_automatic_composition): Mark vars as initialized,
13630 with a FIXME (Bug#8290).
13632 character.h: Rename locals to avoid shadowing.
13633 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13634 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13635 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13636 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13637 to avoid shadowing.
13639 * textprop.c (property_change_between_p): Remove; unused.
13641 * intervals.c (interval_start_pos): Now static.
13643 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13645 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13646 Rename locals to avoid shadowing.
13648 * sound.c (wav_play, au_play, Fplay_sound_internal):
13649 Fix pointer signedness.
13650 (alsa_choose_format): Remove unused local var.
13651 (wav_play): Initialize a variable to 0, to prevent undefined
13652 behavior (Bug#8278).
13654 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13656 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13658 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13659 clobbering (Bug#8298).
13660 * sysdep.c (sys_subshell): Likewise.
13661 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13663 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13664 This should get cleaned up, so that child_setup has the
13665 same signature on all platforms.
13667 * callproc.c (call_process_cleanup): Now static.
13668 (relocate_fd): Rename locals to avoid shadowing.
13670 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13672 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears

13730 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13732 * deps.mk (unexalpha.o): Remove; unused.
13734 New file unexec.h, the (simple) interface for unexec (Bug#8267).

13793 * lisp.h (get_system_name, get_operating_system_release):
13794 Move decls here, to check interfaces.
13795 * process.c (get_operating_system_release): Move decl to lisp.h.
13796 * xrdb.c (get_system_name): Likewise.

13798 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13799 some of which prompt warnings from gcc -Wbad-function-cast.
13800 (Fformat_time_string, Fencode_time, Finsert_char):

13829 (Fmemory_limit): Cast sbrk's returned value to char *.

13836 Use functions, not macros, for up- and down-casing (Bug#8254).
13837 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13838 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13839 to use the following functions instead of these macros.
13840 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13841 EMACS_INT, since callers assume the returned value fits in int.
13842 (upcase1): Likewise, for UPCASE_TABLE.
13843 (uppercasep, lowercasep, upcase): New static inline functions.
13844 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13850 (regex_compile, re_search_2, re_match_2_internal):
13851 Remove unused local vars.

13854 (regex_compile, re_match_2_internal): Mark locals as initialized.
13855 (RETALLOC_IF): Define only if needed.
13856 (WORDCHAR_P): Likewise. This one is never needed, but is used
13857 only in a comment talking about a compiler bug, so put inside
13858 the #if 0 of that comment.
13859 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13860 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

13873 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13875 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13876 All uses changed.
13877 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13878 Rename locals to avoid shadowing.
13879 (Fvertical_motion): Mark locals as initialized.
13881 * casefiddle.c (casify_object, casify_region): Now static.
13882 (casify_region): Mark local as initialized.

13886 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13887 New macros, so that the caller can use some names other than
13888 gcpro1, gcpro2, etc.
13889 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13890 of the new macros.
13891 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13892 argument, for consistency with GCPRO2_VAR, etc: it is now the
13893 prefix of the variable, not the variable itself. All uses
13894 changed.
13895 * dired.c (directory_files_internal, file_name_completion):
13896 Rename locals to avoid shadowing.
13898 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13899 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13900 dired.c's scmp function, had undefined behavior.
13901 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13902 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13903 * buffer.h: ... to here, because these macros use current_buffer,
13904 and the new implementation with inline functions needs to have
13905 current_buffer in scope now, rather than later when the macros
13906 are used.
13907 (downcase, upcase1): New static inline functions.
13908 (DOWNCASE, UPCASE1): Reimplement using these functions.
13909 This avoids undefined behavior in expressions like
13910 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13911 from race conditions in accessing the global variables
13912 case_temp1 and case_temp2.
13913 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13914 * lisp.h (case_temp1, case_temp2): Remove their decls.
13915 * character.h (ASCII_CHAR_P): Move from here ...
13916 * lisp.h: ... to here, so that the inline functions mentioned
13917 above can use them.
13919 * dired.c (directory_files_internal_unwind): Now static.
13921 * fileio.c (file_name_as_directory, directory_file_name):
13922 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13923 Now static.
13924 (file_name_as_directory): Use const pointers when appropriate.
13925 (Fexpand_file_name): Likewise. In particular, newdir might
13926 point at constant storage, so make it a const pointer.
13927 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13928 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13929 signedness issues.
13930 (Fset_file_times, Finsert_file_contents, auto_save_error):
13931 Rename locals to avoid shadowing.
13933 * minibuf.c (choose_minibuf_frame_1): Now static.
13934 (Ftry_completion, Fall_completions): Rename or remove locals
13935 to avoid shadowing.
13937 * marker.c (bytepos_to_charpos): Remove; unused.
13939 * lisp.h (verify_bytepos, count_markers): New decls,
13940 so that gcc does not warn that these functions aren't declared.
13942 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13943 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13944 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13945 (copy_text): Remove unused local var.
13947 * filelock.c (within_one_second): Now static.
13948 (lock_file_1): Rename local to avoid shadowing.
13950 * buffer.c (fix_overlays_before): Mark locals as initialized.
13951 (fix_start_end_in_overlays): Likewise. This function should be
13952 simplified by using pointers-to-pointers, but that's a different
13953 matter.
13954 (switch_to_buffer_1): Now static.
13955 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13956 (report_overlay_modification): Rename locals to avoid shadowing.
13958 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13959 Fix pointer signedness issue.
13960 (sys_subshell): Mark local as volatile if checking for lint,
13961 to suppress a gcc -Wclobbered warning that does not seem to be right.
13962 (MAXPATHLEN): Define only if needed.
13964 * process.c (serial_open, serial_configure): Move decls from here ...
13965 * systty.h: ... to here, so that they can be checked.
13967 * fns.c (get_random, seed_random): Move extern decls from here ...
13968 * lisp.h: ... to here, so that they can be checked.
13970 * sysdep.c (reset_io): Now static.
13971 (wait_for_termination_signal): Remove; unused.
13973 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13974 (copy_keymap_item, append_key, push_text_char_description):
13975 Now static.
13976 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13977 (DENSE_TABLE_SIZE): Remove; unused.
13978 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13979 (describe_map_tree):
13980 Rename locals to avoid shadowing.
13982 * keyboard.c: Declare functions static if they are not used elsewhere.
13983 (echo_char, echo_dash, cmd_error, top_level_2):
13984 (poll_for_input, handle_async_input): Now static.
13985 (read_char, kbd_buffer_get_event, make_lispy_position):
13986 (make_lispy_event, make_lispy_movement, apply_modifiers):
13987 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
13988 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
13989 (Fread_key_sequence_vector): Rename locals to avoid shadowing.

13999 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
14000 (DEFINE_DUMMY_FUNCTION): New macro.
14001 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
14002 Use it.
14003 (main): Add casts to avoid warnings
14004 if GCC considers string literals to be constants.
14006 * lisp.h (fatal_error_signal): Add decl, since it's exported.
14008 * dbusbind.c: Pointer signedness fixes.
14009 (xd_signature, xd_append_arg, xd_initialize):
14010 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14011 (Fdbus_method_return_internal, Fdbus_method_error_internal):

14013 (Fdbus_register_signal): Use SSDATA when the context wants char *.
14015 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
14016 if GCC considers string literals to be constants.

14056 * w32term.c (Vwindow_system, updating_frame):
14057 * w32uniscribe.c (initialized, uniscribe_font_driver):
14058 Remove unneeded extern declarations.
14060 2011-03-14 Chong Yidong <cyd@stupidchicken.com>
14062 * buffer.c (Fmake_indirect_buffer): Fix incorrect assertions.
14064 2011-03-13 Chong Yidong <cyd@stupidchicken.com>
