176 * alloc.c (listn): Fix the order the arguments are consed onto the
179 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
180 enumeration constants, as PURE and HEAP are too general, and clash
181 with other headers and sources, such as gmalloc.c and the
182 MS-Windows system headers. All users changed.
184 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

199 Improve GDB symbol export (Bug#12036).
200 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different

202 complains about the types in the unevaluated arm when the argument
203 is an integer literal.
204 (xgetint): Simplify expression.
205 * alloc.c (gdb_make_enums_visible): New constant. This ports to
206 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
207 Zaretskii in <http://bugs.gnu.org/12036#13>.
208 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer

254 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
255 emacs.c, as this is a more-suitable home. Had this been done earlier
256 the fix for 12036 would have avoided some of the problems noted in
257 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
258 would have been more obvious.
259 * emacs.c: Do not include <verify.h>; no longer needed.
260 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

268 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
269 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
270 not be usable in #if. This simplifies things.
272 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
274 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
276 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

279 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
280 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
281 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
282 Adjust to changes in lisp.h and emacs.c, by using
283 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
284 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
285 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
286 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
287 instead of gdb_valbits.
288 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
289 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
290 instead of gdb_array_mark_flag.
291 (xboolvector): Get size from $->size, not $->header.size.
292 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
293 (xreload, hook-run, hookpost-run): Remove.
294 * emacs.c: Include <verify.h>.
295 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
296 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
298 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
299 (gdb_USE_LSB_TAG): New enum constants.
300 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

303 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
304 as constants, so they're visible to GDB.

307 Now enum constants, not macros, so they're visible to GDB.
308 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
309 more convenient now. All uses changed.
310 (VALMASK) [USE_LSB_TAG]: Also define in this case.

321 add argument, tune behavior, and adjust all callers.
323 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
325 Use typedef for EMACS_INT, EMACS_UINT.
326 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
327 than macros. This simplifies debugging in the usual case, since
328 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
329 and it allows expressions involving EMACS_INT casts.
330 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
332 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

345 * buffer.c (Fkill_buffer): Adjust indirection counters when the
346 buffer is definitely dead. This should really fix an issue reported
347 by Christoph Scholtes again. (Bug#12007).
348 (init_buffer_once): Initialize indirection counters of
349 buffer_defaults and buffer_local_symbols (for sanity and safety).
351 2012-07-24 Eli Zaretskii <eliz@gnu.org>
353 * xdisp.c (init_iterator): Don't compute dimensions of truncation
354 and continuation glyphs on tooltip frames, leave them at zero.
355 Avoids continued lines in tooltips. (Bug#11832)
357 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

384 Swap buffer text indirection counters in Fbuffer_swap_text.
385 * buffer.c (Fbuffer_swap_text): Swap indirections too.
386 This avoids crash reported by Christoph Scholtes at
387 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
389 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
391 * nsmenu.m (Popdown_data): New struct.
392 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
394 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

414 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
416 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
417 as it's limited by the amount of memory, not by INT_MAX.
419 2012-07-21 Eli Zaretskii <eliz@gnu.org>
421 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
422 in special-event-map. See the discussion at

1145 * s/aix4-2.h (unix): Remove; no longer needed.
1147 EMACS_TIME simplification (Bug#11875).
1148 This replaces macros (which typically do not work in GDB)

1150 The functional style also makes code easier to read and maintain.
1151 * systime.h: Include <sys/time.h> on all hosts, not just if
1152 WINDOWSNT, since 'struct timeval' is needed in general.

1192 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1193 Prefer snprintf to strncpy.
1194 * nsterm.m (ns_term_init):
1195 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1196 * nsterm.m (ns_term_init):
1197 Avoid the need for strncpy, by using build_string or
1198 make_unibyte_string directly. Use dtoastr, not snprintf.
1199 * process.c (Fmake_network_process): Diagnose service names that
1200 are too long, rather than silently truncating them or creating
1201 non-null-terminated names.

1218 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1219 where argument type is known to be a Lisp_Cons.

1281 (init_lread) [HAVE_NS]: Use ns_load_path.

1291 (ns_init_paths): Do not set EMACSPATH.

1351 Move marker debugging code under MARKER_DEBUG.
1352 * marker.c (MARKER_DEBUG): Move marker debugging code under

1376 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1378 * xdisp.c (display_line): Avoid warning about implicit declaration
1381 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1383 * lisp.h: Remove empty conditional.
1385 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1387 * lread.c (load_path_check): Now static.
1389 Fix some minor --with-ns problems found by static checking.
1390 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1391 (x_set_font) [!HAVE_X_WINDOWS]:
1392 * image.c (xpm_load_image) [HAVE_NS]:
1393 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1394 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1395 Remove unused local.
1396 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1397 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1398 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1399 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1400 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1401 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1402 Fix pointer signedness problem.
1403 * xfaces.c (FRAME_X_FONT_TABLE):
1404 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1406 2012-07-07 Glenn Morris <rgm@gnu.org>
1408 * lread.c (load_path_check): New function, split from init_lread.
1409 (init_lread): Reorganize. Motivation:
1410 If EMACSLOADPATH is set, check/warn about that rather than the
1411 defaults, which we are not going to use. Hence we can remove
1412 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1413 Don't warn if site-lisp directories are missing.
1414 If not installed, start from a blank load-path, since
1415 PATH_LOADSEARCH refers to the eventual installation directories.
1417 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1419 Support truncation and continuation glyphs on GUI frames, when
1420 fringes are disabled. (Bug#11832)
1421 * xdisp.c (init_iterator): Get dimensions of truncation and
1422 continuation glyphs even if on GUI frames. Adjust
1423 it->last_visible_x on GUI frames when the left or right fringes,
1424 or both, are absent.
1425 (start_display, move_it_in_display_line_to): Handle the case of a
1426 GUI frame without a fringe to display continuation or truncation
1428 (insert_left_trunc_glyphs): Support GUI frames: make sure
1429 truncation glyphs overwrite enough glyphs from the current line to
1430 have sufficient space in pixels.
1431 (display_line): Support truncation and continuation glyphs on GUI
1432 frames. If some spare pixels are left on the line after inserting
1433 the truncation glyphs, fill that space with a stretch glyph of a
1434 suitably computed width.
1436 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1437 produce_glyphs, to support GUI sessions.
1439 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1441 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1443 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1445 Do not require float-time's arg to fit in time_t (Bug#11825).
1446 This works better on hosts where time_t is unsigned, and where
1447 float-time is applied to the (negative) difference between two times.
1448 * editfns.c (decode_time_components): Last arg is now double *,
1449 not int *, and means to store all the result as a double, without
1450 worrying about whether the seconds part fits in time_t.
1451 All callers changed.
1452 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1453 All callers changed.
1454 (Ffloat_time): Do not fail merely because the specified time falls
1455 outside of time_t range.
1457 2012-07-07 Glenn Morris <rgm@gnu.org>
1459 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1460 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

1463 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1465 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1466 Update dependencies.
1468 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1470 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1472 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1473 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1474 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1475 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1476 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1477 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1479 * xfont.c (compare_font_names): Redo to omit the need for casts.
1481 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1483 * xfns.c (Fx_change_window_property): Doc fix.
1484 * w32fns.c (Fx_change_window_property): Doc fix.
1486 * w32fns.c (Fx_window_property): Accept the same arguments as the
1487 X Windows version. Doc fix.
1488 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1490 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1491 Eli Zaretskii <eliz@gnu.org>
1493 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1494 Windows-specific code from nt/config.nt moved here.
1495 Obsolete settings removed.
1497 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1499 * process.c: Avoid unnecessary calls to gettime.
1500 (wait_reading_process_output): Don't get the time of day
1501 when gobbling data immediately and not waiting, as there's no need
1502 for it in that case. This removes a FIXME.
1504 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1506 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1507 is defined (Bug#11768).
1509 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1511 Fix marker debugging code.
1512 * marker.c (byte_char_debug_check): Do not perform the check
1513 if buffer is not multibyte.
1514 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1515 Call byte_char_debug_check with correct arguments.
1517 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1519 Compile marker debugging code only if ENABLE_CHECKING is defined.
1520 * marker.c (byte_char_debug_check, count_markers):
1521 Use only if ENABLE_CHECKING is defined.
1522 (byte_debug_flag): Remove.
1523 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1524 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1526 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1528 Avoid code repetition in marker-related functions.
1529 * marker.c (attach_marker): New function.
1530 (Fset_marker, set_marker_restricted, set_marker_both)
1531 (set_marker_restricted_both): Use it.
1532 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1533 Consistently rename charno to charpos.
1534 (marker_position): Add eassert.
1535 (marker_byte_position): Convert to eassert.
1537 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1539 Simplify list operations in unchain_overlay and unchain_marker.
1540 * buffer.c (unchain_overlay): Simplify. Add comment.
1541 * marker.c (unchain_marker): Simplify. Fix comments.
1543 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1545 Introduce fast path for the widely used marker operation.
1546 * alloc.c (build_marker): New function.
1547 * lisp.h (build_marker): New prototype.
1548 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1549 * composite.c (autocmp_chars): Likewise.
1550 * editfns.c (buildmark): Remove.
1551 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1552 (save_restriction_save): Use build_marker.
1553 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1554 * window.c (save_window_save): Likewise.
1556 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1558 Do not use Fdelete_overlay in delete_all_overlays
1559 to avoid redundant calls to unchain_overlay.
1560 * buffer.c (drop_overlay): New function.
1561 (delete_all_overlays, Fdelete_overlay): Use it.
1562 * minibuf.c (get_minibuffer): Fix comment.
1564 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1566 Port to OpenBSD 5.1 amd64.
1567 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1568 This is needed for OpenBSD, and should be harmless on all BSD systems.
1569 Also, include <sys/sysctl.h>, as it should be available on all
1570 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1571 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1572 use p_pid member, not kp_proc.pid.
1574 2012-07-06 Glenn Morris <rgm@gnu.org>
1576 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1578 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1580 More xmalloc and related cleanup.
1581 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1582 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
1583 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

1585 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
1586 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
1587 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
1588 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1589 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1591 Omit needless casts involving void * pointers and allocation.
1592 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1593 as the former is more robust if P's type is changed.
1594 Prefer xzalloc to xmalloc + memset 0.
1595 Simplify malloc-or-realloc to realloc.
1596 Don't worry about xmalloc returning a null pointer.
1597 Prefer xstrdup to xmalloc + strcpy.
1598 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1600 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1601 alloca of a constant.
1603 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1605 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1606 hscroll is larger than the line width. Fixes long and futile
1607 looping inside extend_face_to_end_of_line (on a TTY) producing
1608 glyphs that are not needed and thrown away.
1610 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1612 * marker.c (set_marker_restricted_both): Simplify by using
1615 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1617 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1619 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1621 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
1622 not defined (Bug#11768).
1623 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1624 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1625 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1626 followed by gtk_box_set_homogeneous (Bug#11768).
1627 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1628 (update_theme_scrollbar_width, xg_create_scroll_bar):
1629 Use gtk_scrollbar_new (Bug#11768).
1630 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1631 (is_box_type): New function (Bug#11768).
1632 (xg_tool_item_stale_p): Call is_box_type.
1633 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1634 with default display (Bug#11768).
1636 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1638 * xdisp.c (window_hscroll_limited): New function.
1639 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1640 coordinates when window's hscroll is set to insanely large
1643 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1645 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1646 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1648 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1651 * lisp.h (xzalloc): New prototype. Omit needless casts.
1652 * alloc.c (xzalloc): New function. Omit needless casts.
1653 * charset.c: Omit needless casts. Convert all calls to
1654 xmalloc with following memset to xzalloc.

1704 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1706 * fileio.c (time_error_value): Check the right error number.
1707 Problem reported by Troels Nielsen in
1708 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1710 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1712 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1713 This should be fixed in a better way; see Eli Zaretskii in
1714 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1715 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1717 * fileio.c (time_error_value): Rename from special_mtime.
1718 The old name's problems were noted by Eli Zaretskii in
1719 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1721 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1722 This variable's comment says Emacs needs at least one GDB-visible
1723 symbol of type enum pvec_type, to work around GDB problems.
1724 The symbol's value doesn't matter.
1726 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1727 that causes compilation to fail on pre-C99 compilers.
1729 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1731 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1732 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1734 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1736 * buffer.c (init_buffer_once): Fix initialization of
1737 headers for buffer_defaults and buffer_local_symbols.
1738 Reported by Juanma Barranquero <lekktu@gmail.com>.
1740 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1742 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1743 * lisp.h (enum pvec_type): Use fewer bits.
1744 (PSEUDOVECTOR_SIZE_BITS): New constant.
1745 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1746 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1747 change in pvec_type.
1748 (PSEUDOVECTOR_TYPEP): New macro.
1749 (TYPED_PSEUDOVECTORP): Use it.
1750 * fns.c (internal_equal): Adapt code to extract pvectype.
1751 * emacs.c (gdb_pvec_type): Update type.
1752 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1753 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1754 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1755 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1756 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1757 abusing vector->header.next.nbytes.
1758 (live_vector_p): Use PVEC_TYPE.
1759 (mark_object): Adapt code to extract pvectype. Use switch.
1761 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1763 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1764 Tighten new eassert a bit.
1766 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1768 Fix compilation with --enable-gcc-warnings and -O1
1770 * doprnt.c (doprnt): Change type of tem to int, initialize
1771 to avoid compiler warning. Add eassert.
1772 * search.c (simple_search): Initialize match_byte to avoid
1773 compiler warning. Add eassert.
1775 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1777 Avoid weird behavior with large horizontal scrolls.
1778 Without this change, for example, large hscroll values would
1779 mess up Emacs's display on Fedora 15 x86, presumably due to
1780 overflows in int calculations in the display code.
1781 Also, if buffers had long lines, Emacs would freeze.
1782 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1783 (set_window_hscroll): New function, containing the old guts of
1784 Fset_window_hscroll. Return the clipped value.
1785 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1786 This avoids the need to check against PTRDIFF_MAX.
1788 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1790 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1792 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1794 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1796 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1797 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1798 since GCC 4.4.6 issues a bogus warning for them.
1800 Fix bugs in file timestamp newness comparisons.
1801 * fileio.c (Ffile_newer_than_file_p):
1802 * lread.c (Fload): Use full timestamp resolution of files,
1803 not just the 1-second resolution, so that files that are only
1804 slightly newer still count as newer.
1805 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1806 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1808 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1810 * fileio.c: Improve handling of file time marker. (Bug#11852)
1811 (special_mtime): New function.
1812 (Finsert_file_contents, Fverify_visited_file_modtime):
1813 Use it to set special mtime values consistently.
1815 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1817 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1818 marker for non-existing file. (Bug#11852)
1820 2012-07-03 Glenn Morris <rgm@gnu.org>
1822 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1823 and did not make it into globals.h).
1825 2012-07-03 Tom Tromey <tromey@redhat.com>
1827 * window.c (Fset_window_margins, Fset_window_fringes)
1828 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1829 * textprop.c (Fprevious_property_change): No longer static.

1871 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1872 values which aren't power of 2.
1873 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1874 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1877 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1879 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

1883 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1885 * alloc.c (allocate_vector_block): Remove redundant
1886 calls to mallopt if DOUG_LEA_MALLOC is defined.
1887 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1888 avoid calls to mallopt if zero_vector is returned.
1890 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1892 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1893 is enabled, avoid dereferencing NULL current_sblock if
1896 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1898 Cleanup basic buffer management.
1899 * buffer.h (struct buffer): Change layout to use generic vector
1900 marking code. Fix some comments. Change type of 'clip_changed'
1901 to bitfield. Remove unused #ifndef old.
1902 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1903 (GET_OVERLAYS_AT): Fix indentation.

1908 * alloc.c (allocate_buffer): Adjust to match new layout of
1909 struct buffer. Fix comment.
1910 (mark_overlay): New function.

1912 Lisp area of struct buffer.
1913 (mark_object): Use it. Adjust marking of misc objects
1914 and related comments.
1916 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1918 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1919 wrapper that is not needed because the wrapped code is a no-op (zero
1920 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1921 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1923 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1925 * alloc.c (mark_buffer): Simplify. Remove prototype.
1926 (mark_object): Add comment. Reorganize marking of vector-like
1927 objects. Use CHECK_LIVE for all vector-like objects except buffers
1928 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1929 redundant calls to mark_vectorlike for bool vectors.
1931 2012-06-30 Glenn Morris <rgm@gnu.org>
1933 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1935 * epaths.in (PATH_SITELOADSEARCH): New.
1936 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1937 This is rather than relying on --enable-locallisppath elements
1938 having "site-lisp" in their names. (Bug#10208#25, 11658)
1940 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1942 * w32proc.c (sys_select): Accept and ignore one more argument.
1944 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1946 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1947 (pselect) [!MS_DOS]: Redirect to sys_select.
1949 * sysdep.c: Don't include dos.h and dosfns.h.
1951 * process.c (sys_select):
1952 * msdos.c (sys_select): Accept one more argument and ignore it.
1954 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1955 adapt data types and code to that.
1958 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1959 which clashes with the gnulib function of the same name.
1961 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1963 * font.c (font_style_to_value, font_style_symbolic)
1964 (font_prop_validate_style): Add type checks for values in
1967 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1969 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1972 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1974 * xdisp.c (try_window_id): Undo last change.
1976 * w32.c (getwd): Adjust commentary about startup_dir.
1977 (init_environment): Always call sys_access, even in non-MSVC
1978 builds. Don't chdir to the directory of the Emacs executable.
1979 This undoes code from 1997 which was justified by the need to
1980 "avoid conflicts when removing and renaming directories". But its
1981 downside was that every relative file name was being interpreted
1982 relative to the directory of the Emacs executable, which can never
1983 be TRT. In particular, it broke sys_access when called with
1984 relative file names.
1985 (sys_access): Map GetLastError to errno.
1987 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1989 * window.h (struct window): Change type of 'fringes_outside_margins'

2009 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

2029 * window.h (struct window): Change type of 'hscroll',
2030 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

2032 Adjust users accordingly.
2033 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2034 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2035 from EMACS_INT to ptrdiff_t.

2111 * alloc.c (allocate_string): Omit intervals initialization.
2112 * alloc.c (make_uninit_multibyte_string): Initialize intervals

2171 a better opportunity to optimize away calls to strlen when the

2173 * image.c (imagemagick_error): Convert to build_string.
2174 * w32proc.c (sys_spawnve): Likewise.

2177 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2179 Use sprintf return value instead of invoking strlen on result.
2180 In the old days this wasn't portable, since some sprintf
2181 implementations returned char *. But they died out years ago and
2182 Emacs already assumes sprintf returns int.
2183 Similarly for float_to_string.
2184 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2191 * xfns.c (syms_of_xfns):
2192 Use sprintf or float_to_string result to avoid need to call strlen.
2193 * data.c (Fnumber_to_string):
2194 Use make_unibyte_string, since the string must be ASCII.
2195 * lisp.h, print.c (float_to_string): Now returns int length.
2196 * term.c (produce_glyphless_glyph):
2197 Use sprintf result rather than recomputing it.
2199 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

2232 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2235 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2237 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2238 instead of truncating it to 63 (admittedly a generous limit).
2240 * process.c: Fix spelling and caps in comments.
2242 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

2298 * keyboard.c (kbd_buffer_get_event):

2321 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2322 Privately reported by Herbert J. Skuhra.
2323 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2325 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

2360 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2361 Privately reported by Herbert J. Skuhra.
2362 [__FreeBSD__]: Remove "*/" typo after "#include".
2363 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2364 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2365 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2366 Don't assume EMACS_TIME and struct timeval are the same type.
2368 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2370 Support higher-resolution time stamps (Bug#9000).
2371 The time stamps are only nanosecond-resolution at the C level,
2372 since that's the best that any real-world system supports now.
2373 But they are picosecond-resolution at the Lisp level, as that's
2374 easy, and leaves room for future OS improvements.
2376 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2379 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2380 Don't get current time unless it's needed.
2382 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2383 now provides it if it's absent.
2384 (start_atimer): Port to higher-res time stamps.
2385 Check for time stamp overflow. Don't get current time more
2386 often than is needed.
2388 * buffer.h (struct buffer): Buffer modtime now has high resolution.

2396 (struct image): Timestamp now has higher resolution.
2398 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2399 has at least microseconds now. All uses removed.

2401 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2403 * editfns.c (time_overflow): Now extern.

2415 * fileio.c: Include <stat-time.h>
2416 (Fcopy_file): Copy higher-resolution time stamps.
2417 Prefer to set the time stamp via a file descriptor if that works.

2420 (Fvisited_file_modtime, Fset_visited_file_modtime):
2421 Support higher-resolution time stamps.
2423 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2425 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2427 * image.c (prepare_image_for_display, clear_image_cache)
2428 (lookup_image): Port to higer-resolution time stamps.
2430 * keyboard.c (start_polling, bind_polling_period):
2431 Check for time stamp overflow.

2434 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2435 Port to higher-resolution time stamps. Do not assume time_t is signed.
2436 (decode_timer): New function. Timers are now vectors of length 9,
2437 not 8, to accommodate the picosecond component.
2438 (timer_check_2): Use it.
2440 * nsterm.m (select_timeout, timeval_subtract): Remove.
2441 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2442 as they're a bit more accurate and handle overflow better.
2443 (ns_select): Change prototype to be compatible with pselect.
2444 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2445 * nsterm.h (ns_select): Adjust prototype.
2447 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2448 us-resolution time stamps.
2449 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2451 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2453 * lisp.h (time_overflow): New decl.
2454 (wait_reading_process_output): First arg is now intmax_t, not int,
2455 to accommodate larger waits.
2457 * process.h (struct Lisp_Process.read_output_delay):
2458 Now counts nanoseconds, not microseconds.
2459 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

2464 (Faccept_process_output, wait_reading_process_output):
2465 Check for time stamp overflow. Do not assume time_t is signed.
2466 (select_wrapper): Remove; we now use pselect.
2467 (Fprocess_attributes): Now generates ns-resolution time stamps.
2469 * sysdep.c: Include utimens.h. Don't include utime.h
2470 or worry about struct utimbuf; gnulib does that for us now.
2471 (gettimeofday): Remove; gnulib provides a substitute.
2472 (make_timeval): New function.
2473 (set_file_times): Now sets ns-resolution time stamps.
2474 New arg FD; all uses changed.
2475 (time_from_jiffies, ltime_from_jiffies, get_up_time)

2477 Now returns ns-resolution time stamp. All uses changed.
2478 Check for time stamp overflow.
2480 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2481 provides a substitute now.
2483 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2484 since it guarantees struct timespec.
2485 (EMACS_TIME): Now struct timespec, so that we can support
2486 ns-resolution time stamps.
2487 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2488 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2489 (EMACS_USECS): Remove.
2490 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2491 so multiply the arg by 1000 before storing it.
2492 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2494 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2495 Port to ns-resolution time stamps.
2496 (EMACS_TIME_NEG_P): Remove; replaced by....

2501 (make_timeval, make_lisp_time, decode_time_components): New decls.
2502 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2503 that it mishandled time_t overflow. You can't compare by subtracting!
2504 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2505 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2516 (w32_get_internal_run_time):
2517 Port to higher-resolution Emacs time stamps.

2523 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2524 for compatibility with pselect. Support ns-resolution time stamps.

2528 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2529 Check for time stamp overflow, and support ns-resolution time stamps.
2531 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2532 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2533 (timeval_subtract): Remove; no longer needed.
2534 (XTflash, XTring_bell, x_wait_for_event):
2535 Port to ns-resolution time stamps. Don't assume time_t is signed.

2541 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2543 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2544 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2545 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2546 staticidx goes up to 1597 out of 1600 = 0x640.)
2548 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2550 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2551 Otherwise, the umask might be mistakenly 0 while handling input signals.

2584 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2585 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2586 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2587 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2588 (METER_1, METER_2): Simplify.

2596 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2597 gets killed during executing of this function (Bug#11665).
2598 Try to always return Qt when the buffer has been actually killed.
2599 (Vkill_buffer_query_functions): In doc-string say that functions
2600 run by this hook should not change the current buffer.
2602 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2604 Fix recently-introduced process.c problems found by static checking.

2625 This removes the need for CHECK.
2626 (CHECK): Remove. Its comments about always evaluating its
2627 argument were confusing, as 'eassert' typically does not evaluate
2630 * coding.c (produce_chars): Use ptrdiff_t, not int.
2632 * xterm.c (x_draw_underwave): Check for integer overflow.
2633 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2806 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2807 * alloc.c (make_number) [!defined make_number]:
2808 Remove, as lisp.h always defines this now.
2809 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
2810 (roundup_size): Verify that it is a power of 2.
2811 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
2812 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
2813 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
2814 -DUSE_LSB_TAG=0, to override the automatically-selected default.
2815 USE_LSB_TAG now is always defined to be either 0 or 1.
2817 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2818 code works fine either way, and efficiency is not a concern here,
2819 as the union type is for debugging, not for production.
2820 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2821 Use an inline function on all platforms when using the union type,
2822 since this is simpler and 'static inline' can be used portably
2824 (LISP_INITIALLY_ZERO): New macro.
2825 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2826 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
2828 2012-06-12 Glenn Morris <rgm@gnu.org>

2853 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
2854 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
2855 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

2894 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
2895 dbus_type_is_basic if available.
2896 (xd_extract_signed, xd_extract_unsigned): Rename from
2897 extract_signed and extract_unsigned, respectively. Adapt callers.
2899 2012-06-09 Chong Yidong <cyd@gnu.org>
2901 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

2908 * xdisp.c (vmessage): Treat frame message as multibyte.
2909 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2910 would generate the diagnostic "Making \302\247 buffer-local while
2913 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2915 * dispnew.c (showing_window_margins_p): Undo last change, which

2929 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2931 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2933 * alloc.c (allocate_vectorlike): Fix last change.
2935 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2937 Block-based vector allocation of small vectors.
2938 * lisp.h (struct vectorlike_header): New field `nbytes',
2939 adjust comment accordingly.
2940 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
2941 to denote vector blocks. Adjust users (live_vector_p,
2942 mark_maybe_pointer, valid_lisp_object_p) accordingly.

2962 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2964 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2966 * doprnt.c (doprnt): Truncate multibyte char correctly.
2967 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2968 would mishandle a string argument "Xc" if X was a multibyte
2969 character of length 2: it would truncate after X's first byte
2970 rather than including all of X.
2972 2012-06-06 Chong Yidong <cyd@gnu.org>
2974 * buffer.c (word_wrap): Doc fix.

3023 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3024 Convert pctcpu and pctmem to Lisp float properly.
3025 Let the compiler fold better, as 100.0/0x8000 is exact.
3027 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3029 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3032 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3034 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3036 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3038 For a 'struct window', replace some Lisp_Object fields to
3039 bitfields where appropriate, remove unused fields.
3040 * window.h (struct window): Remove unused 'last_mark_x' and
3041 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3042 change it's type from Lisp_Object to bitfield.
3043 Change type of 'force_start', 'optional_new_start',
3044 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3045 fields from Lisp_Object to bitfield. Adjust users accordingly.
3047 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3049 Pacify gcc -Wdouble-precision when using Xaw.
3050 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3051 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3052 Use 'float' consistently, rather than 'float' in most places
3053 and 'double' in a couple of places.
3055 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3057 * xdisp.c (handle_stop): Detect whether we have overlay strings
3058 loaded by testing it->current.overlay_string_index to be
3059 non-negative, instead of checking whether n_overlay_strings is
3060 positive. (Bug#11587)
3062 2012-05-31 Chong Yidong <cyd@gnu.org>
3064 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3066 * doc.c (Fsubstitute_command_keys): Doc fix.
3068 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3070 * search.c (search_buffer): Remove calls to
3071 r_alloc_inhibit_buffer_relocation, as it is now called by
3072 maybe_unify_char, which was the cause of relocation of buffer text
3075 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3077 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3078 for the duration of call to load_charset, to avoid problems with
3079 callers of maybe_unify_char that access buffer text through C
3082 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3083 decrement the inhibition flag, instead of just setting or
3086 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3088 Remove obsolete '#define static' cruft.
3089 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3090 This #undef was "temporary" in 2000; it is no longer needed
3091 now that '#define static' has gone away.
3092 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3093 (gray_bitmap_bits): Remove; no longer needed.
3094 All uses replaced with definiens.
3095 * xterm.c: Include "bitmaps/gray.xbm".
3097 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3099 Clean up __executable_start, monstartup when --enable-profiling.
3100 The following changes affect the code only when profiling.
3101 * dispnew.c (__executable_start): Rename from safe_bcopy.
3102 Define only on platforms that need it.
3103 * emacs.c: Include <sys/gmon.h> when profiling.
3104 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3105 (__executable_start): Remove decl, since lisp.h does it now.
3106 (safe_bcopy): Remove decl; no longer has that name.
3107 (main): Coalesce #if into single bit of code, for simplicity.
3108 Cast pointers to uintptr_t, since standard libraries want integers

3133 * lread.c (read1): Tiny simplification.
3135 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3137 Do not create empty overlays with the evaporate property (Bug#9642).
3138 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3139 Bug#9642, but explicitly check that the buffer the overlay would
3140 be moved to is live and rearrange lines to make sure that errors
3141 will not put the overlay in an inconsistent state.
3142 (Fdelete_overlay): Cosmetics.
3144 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3146 * w32term.c (my_bring_window_to_top): New function.
3147 (x_raise_frame): Use handle returned by DeferWindowPos, which

3152 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3153 by calling BringWindowToTop.

3158 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3160 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3161 This avoids undefined behavior that might cause the eassert
3162 to not catch an out-of-range value.
3164 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3166 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3178 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3180 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3181 Only r_alloc_inhibit_buffer_relocation needed to be added;
3182 the others were already declared.
3184 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3185 before checking whether it's out of range. Put the check inside
3187 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3189 2012-05-27 Ken Brown <kbrown@cornell.edu>
3191 * callproc.c (Fcall_process): Restore a line that was accidentally
3192 commented out in the 2011-02-13 change (bug#11547).

3196 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3197 defined on ralloc.c.
3199 * buffer.c [REL_ALLOC]: Remove prototypes of
3200 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3201 they are now on lisp.h.
3203 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3205 * search.c (search_buffer): Use it to inhibit relocation of buffer
3206 text while re_search_2 is doing its job, because re_search_2 is
3207 passed C pointers to buffer text. (Bug#11519)
3209 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3212 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3213 state after an additional call to move_it_in_display_line_to, keep
3214 the values of it->max_ascent and it->max_descent found for the
3216 (pos_visible_p): Revert the comparison against bottom_y to what it
3217 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3220 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3222 Fix coding-related core dumps with gcc -ftrapv.
3223 The code was computing A - B, where A and B are pointers, and B is
3224 random garbage. This can lead to core dumps on platforms that
3225 have special pointer registers, and it also leads to core dumps on
3226 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3227 A - B only when B is initialized properly.
3228 * coding.c (coding_set_source, coding_set_destination): Return void.
3229 (coding_change_source, coding_change_destinations): New functions,
3230 with the old behaviors of coding_set_source and coding_set_destination.
3231 All callers that need an offset changed to use these new functions.
3233 2012-05-26 Glenn Morris <rgm@gnu.org>
3235 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3237 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3239 Extend mouse support on W32 text-mode console.
3240 * xdisp.c (draw_row_with_mouse_face):
3241 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3243 * w32console.c: Include window.h.
3244 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3246 (initialize_w32_display): Initialize mouse-highlight data.
3248 * w32inevt.c: Include termchar.h and window.h.
3249 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3250 moves, call note_mouse_highlight. If help_echo changed, call
3251 gen_help_event to produce help-echo message in the echo area.
3252 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3255 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3257 * lread.c (read1): Simplify slightly to avoid an overflow warning
3258 with GCC 4.7.0 on x86-64.
3260 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3262 * bidi.c (bidi_mirror_char): Revert last change: an int is
3263 definitely wide enough here.
3265 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3267 Fix integer width and related bugs (Bug#9874).
3268 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

3272 (make_unibyte_string, make_multibyte_string)
3273 (make_string_from_bytes, make_specified_string)
3274 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3275 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3277 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3278 (allocate_pseudovector):

3299 (Foverlay_recenter, last_overlay_modification_hooks_used)
3300 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3301 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3302 (validate_region): Omit unnecessary test for b <= e,
3303 since that's guaranteed by the previous test.

3305 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3306 (report_overlay_modification):

3308 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3312 * buffer.h: Adjust decls to match defn changes elsewhere.

3317 not int, to avoid needless 32-bit limit on 64-bit hosts.
3318 (exec_byte_code): Use tighter memory-full test, one that checks
3319 for alloca overflow. Don't compute the address of the object just
3320 before an array, as that's not portable. Use EMACS_INT, not
3321 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3322 * callint.c (Fcall_interactively):
3323 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3336 (casify_object): Avoid integer overflow when overallocating buffer.
3337 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3340 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3341 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3344 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3345 For CCL_MapSingle, check that content and value are in int range.

3347 Check that Vcode_version_map_vector is a vector.
3348 (resolve_symbol_ccl_program): Check that vector header is in range.
3349 Always copy the vector, so that we can check its contents reliably
3350 now rather than having to recheck each instruction as it's being
3351 executed. Check that vector words fit in 'int'.
3352 (ccl_get_compiled_code, Fregister_ccl_program)
3353 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3354 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3356 contents are in range.
3357 (Fccl_execute_on_string): Check that status is in range.
3358 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3359 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3360 Accept and return EMACS_INT, not int, because callers can pass values

3367 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3369 avoid mishandling large integers.

3380 Don't rely on undefined behavior with signed left shift overflow.
3381 Don't assume unsigned int fits into fixnum, or that fixnum fits
3382 into unsigned int. Don't require max_code to be a valid fixnum;
3383 that's not true for gb10830 4-byte on a 32-bit host. Allow
3384 invalid_code to be a cons, for the same reason. Require code_offset
3385 to be a character. Avoid int overflow if max_char is close
3387 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3388 this is intended anyway and avoids some undefined behavior.
3389 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3390 INDEX_TO_CODE_POINT, as that's what it expects.
3391 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3392 * charset.h (DECODE_CHAR): Return int, not unsigned;
3393 this is what was intended anyway, and it avoids undefined behavior.
3394 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3395 integer-overflow issues.
3396 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3397 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3398 where the argument is EMACS_INT, and this behavior is not intended.
3399 * chartab.c (Fmake_char_table, Fset_char_table_range)
3400 (uniprop_get_decoder, uniprop_get_encoder):
3401 Don't assume fixnum fits in int.
3402 * cmds.c (move_point): New function, that does the gist of
3403 Fforward_char and Fbackward_char, but does so while checking
3404 for integer overflow more accurately.
3405 (Fforward_char, Fbackward_char): Use it.
3406 (Fforward_line, Fend_of_line, internal_self_insert)
3407 (internal_self_insert):
3408 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4062 * xterm.h: Adjust decls to match defn changes elsewhere.
4063 (struct scroll_bar): Use struct vectorlike_header
4064 rather than rolling our own approximation.
4065 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4067 2012-05-25 Glenn Morris <rgm@gnu.org>
4069 * lisp.mk (lisp): Update for more files being compiled now.
4071 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
4073 * lread.c: Remove `read_pure' which makes no difference.
4074 (read_pure): Remove var.
4075 (unreadpure): Remove function.
4076 (readevalloop): Don't call read_list with -1 flag.

4091 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4094 This directory predates autoconf and is no longer needed nowadays.
4095 Move its few remaining bits of functionality to where they're needed.
4096 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

4105 (EMACS_UINT): Define unconditionally now.
4106 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4107 (BITS_PER_EMACS_INT): New constants, replacing
4108 what used to be in config.h, but not useful in #if.
4109 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4110 define them any more.
4111 (VAL_MAX): New macro.
4113 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4114 BITS_PER_EMACS_INT, in #if.
4115 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4116 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4117 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4118 * s/ms-w32.h (DATA_START):
4119 Move here from removed file m/intel386.h.
4120 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4121 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4123 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4125 Assume C89 or later.

4133 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4134 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4135 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4136 * xterm.c (input_signal_count): Assume volatile works.
4138 2012-05-21 Ken Brown <kbrown@cornell.edu>
4140 * xgselect.c (xg_select): Fix first argument in call to 'select'
4143 2012-05-20 Ken Brown <kbrown@cornell.edu>
4145 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4146 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4148 2012-05-19 Ken Brown <kbrown@cornell.edu>
4150 * xfns.c (x_in_use): Remove `static' qualifier.
4151 * xterm.h (x_in_use): Declare.
4152 * xgselect.c: Include xterm.h.
4153 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4154 and `display_arg' (bug#9754).
4156 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4158 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4160 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4161 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4163 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4165 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4167 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4168 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4170 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4171 reference to image_cache->refcount.
4172 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4174 2012-05-17 Juri Linkov <juri@jurta.org>
4176 * search.c (Fword_search_regexp, Fword_search_backward)
4177 (Fword_search_forward, Fword_search_backward_lax)
4178 (Fword_search_forward_lax): Move functions to isearch.el
4179 (bug#10145, bug#11381).
4181 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4183 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4185 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4187 * lread.c (init_obarray): Declare Qt and Qnil as special.
4189 2012-05-14 Glenn Morris <rgm@gnu.org>
4191 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4192 Put "libexec" before "bin", for the sake of init_callproc_1.
4194 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4196 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4198 * unexaix.c: Port to more-recent AIX compilers.
4199 (report_error, report_error_1, make_hdr, copy_sym)
4200 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4201 Make arguments const char *, not char *, to avoid violations of C
4202 standard and to fix some AIX warnings reported by Gilles Pion.
4204 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4206 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4207 already have overlays loaded.
4208 (handle_single_display_spec): Before returning without displaying
4209 fringe bitmap, synchronize the bidi iterator with the main display
4210 iterator, by calling iterate_out_of_display_property.
4211 (iterate_out_of_display_property): Detect buffer iteration by
4212 testing that it->string is a Lisp string.
4213 (get_next_display_element): When the current object is exhausted,
4214 and there's something on it->stack, call set_iterator_to_next to
4215 proceed with what's on the stack, instead of returning zero.
4216 (set_iterator_to_next): If called at the end of a Lisp string,
4217 proceed to consider_string_end without incrementing string
4218 position. Don't increment display vector index past the end of
4219 the display vector. (Bug#11417)
4220 (pos_visible_p): Don't report a position visible when move_it_to
4221 stopped at the last line of window, which happens to be scanned
4222 backwards by the bidi iteration. (Bug#11464)
4224 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4226 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4227 and right-margin display specs even if the spec is invalid or we
4228 are on a TTY, and thus unable to display on the fringes.
4229 That's because the text with the property will not be displayed anyway,
4230 so we need to signal to the caller that this is a "replacing"
4231 display spec. This fixes display when the spec is invalid or we
4234 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4236 * unexaix.c (make_hdr): Fix typo in prototype.
4237 This bug broke the build on AIX. Problem reported by Gilles Pion.
4239 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4241 * keyboard.c (kbd_buffer_get_event): Read special events also in
4242 batch mode. (Bug#11415)
4244 2012-05-12 Glenn Morris <rgm@gnu.org>
4246 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4248 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4250 * lisp.mk (lisp): Add newcomment.elc.
4252 2012-05-12 Glenn Morris <rgm@gnu.org>
4254 * Makefile.in (MKDIR_P): New, set by configure.
4255 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4257 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4259 Remove unused function hourglass_started.
4260 * dispextern.h (hourglass_started):
4261 * w32fns.c (hourglass_started):
4262 * xdisp.c (hourglass_started): Remove.
4264 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4266 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4267 Update dependencies.
4269 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4271 * xgselect.c (xg_select): Put maxfds+1 into a var.
4272 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4274 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4276 2012-05-10 Dave Abrahams <dave@boostpro.com>
4278 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4279 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4281 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4283 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4284 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4285 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4286 Initialize xd_registered_buses.
4288 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4290 Untag more efficiently if USE_LSB_TAG.
4291 This is based on a proposal by YAMAMOTO Mitsuharu in
4292 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4293 For an admittedly artificial (nth 8000 longlist) benchmark on
4294 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4295 Emacs's overall text size by 1%.
4296 * lisp.h (XUNTAG): New macro.
4297 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4298 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4299 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4300 * eval.c (Fautoload):
4301 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4302 * frame.h (XFRAME): Use XUNTAG.
4304 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4305 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4306 Remove unportable assumptions about print widths of types like
4308 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4309 intptr_t when converting between pointer and integer, to avoid GCC
4310 warnings about wrong width.
4312 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4314 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4315 stack for each reader_thread, instead of defaulting to 8MB
4316 determined by the linker. This avoids failures in creating
4317 subprocesses on Windows 7, see the discussion in this thread:
4318 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4320 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4322 Fix up display of the *Minibuf-0* buffer in the mini window.
4323 * keyboard.c (read_char): Don't clear the echo area if there's no
4325 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4326 contents of *Minibuf-0*) if there's no message displayed in its stead.
4328 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4330 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4333 2012-05-06 Chong Yidong <cyd@gnu.org>
4335 * lisp.mk (lisp): Update.
4337 2012-05-05 Jim Meyering <meyering@redhat.com>
4339 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4341 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4343 * data.c (PUT_ERROR): New macro.
4344 (syms_of_data): Use it. Add new error type `user-error'.
4345 * undo.c (user_error): New function.
4346 (Fprimitive_undo): Use it.
4347 * print.c (print_error_message): Adjust print style for `user-error'.
4348 * keyboard.c (user_error): New function.
4349 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4351 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4353 Do not limit current-time-string to years 1000..9999.
4354 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4355 (Fcurrent_time_string): Support any year that is supported by the
4356 underlying localtime representation. Don't use asctime, as it
4357 has undefined behavior for years outside the range -999..9999.
4359 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4361 Fix race conditions involving setenv, gmtime, localtime, asctime.
4362 Without this fix, interrupts could mess up code that uses these
4363 nonreentrant functions, since setting TZ invalidates existing
4364 tm_zone or tzname values, and since most of these functions return
4365 pointers to static storage.
4366 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4367 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4368 Grow the critical sections to include not just invoking
4369 localtime/gmtime, but also accessing these functions' results
4370 including their tm_zone values if any, and any related TZ setting.
4371 (format_time_string): Last arg is now struct tm *, not struct tm **,
4372 so that the struct tm is saved in the critical section.
4373 All callers changed. Simplify allocation of initial buffer, partly
4374 motivated by the fact that memory allocation needs to be outside
4375 the critical section.
4377 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4379 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4380 with RESET_INTERVAL.
4382 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4383 Remove duplicated buffer name initialization.
4385 2012-05-02 Jim Meyering <jim@meyering.net>
4387 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4389 * xfns.c (x_window): Use xstrdup (Bug#11375).
4391 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4393 * xdisp.c (pos_visible_p): If already at a newline from the
4394 display string before the 'while' loop, don't walk back the glyphs
4395 from it3.glyph_row. Solves assertion violation when the display
4396 string begins with a newline (egg.el). (Bug#11367)
4398 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4400 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4403 2012-05-01 Glenn Morris <rgm@gnu.org>
4405 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4406 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4407 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4408 All were removed before 23.1.

4411 it is always true on relevant platforms.
4413 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4414 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4416 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

4424 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4426 Do not avoid creating empty evaporating overlays (Bug#9642).
4427 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4428 That is, do not delete an evaporating overlay if it becomes
4429 empty after its bounds are adjusted to fit within its buffer.
4430 This fix caused other problems, and I'm reverting it until we get
4431 to the bottom of them.
4433 2012-04-27 Chong Yidong <cyd@gnu.org>
4435 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4437 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4439 * xdisp.c (pos_visible_p): If the window start position is beyond
4440 ZV, start the display from buffer beginning. Prevents assertion
4441 violation in init_iterator when the minibuffer window is scrolled
4444 * window.c (window_scroll_pixel_based): Likewise.
4446 2012-04-27 Chong Yidong <cyd@gnu.org>

4460 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4462 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4463 display element, check also the underlying string or buffer
4464 character. (Bug#11341)
4466 * w32menu.c: Include w32heap.h.
4467 (add_menu_item): If the call to AppendMenuW (via
4468 unicode_append_menu) fails, disable Unicode menus only if we are
4469 running on Windows 9X/Me.
4471 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4473 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4476 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4478 * keyboard.c (read_char): Don't wipe echo area for select window
4479 events: These might get delayed via `mouse-autoselect-window'

4484 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4485 manipulation of :loaded-from data.
4487 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4489 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4490 now a cons (bug#11311).
4492 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4494 Do not create empty overlays with the evaporate property (Bug#9642).
4495 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4496 if it becomes empty after its bounds are adjusted to fit within
4497 its buffer. Without this fix, in a nonempty buffer (let ((o
4498 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4499 yields an empty overlay that has the evaporate property, which is
4500 not supposed to happen.
4502 Fix minor GTK3 problems found by static checking.
4503 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4523 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4524 (__malloc_size_t, __malloc_ptrdiff_t):

4604 since the two debugging options are incompatible.
4605 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4607 (mem_init, mem_insert, mem_insert_fixup):
4608 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4617 * sysdep.c [__FreeBSD__]: Minor cleanups.
4618 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4619 Use Emacs indenting style more consistently. Avoid some casts.
4620 Use 'double' consistently rather than mixing 'float' and 'double'.
4622 2012-04-21 Eduard Wiebe <usenet@pusto.de>
4624 * sysdep.c (list_system_processes, system_process_attributes):
4625 Add implementation for FreeBSD (Bug#5243).

4640 (print_object): Check for cycles even when print-circle is nil and
4641 print-gensym is t, but only check print_depth if print-circle is nil.
4643 2012-04-20 Chong Yidong <cyd@gnu.org>
4645 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4646 set the status to "failed" and ensure that sentinel is run.

4701 New extern decls, to avoid calling undeclared functions.
4702 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4703 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4704 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4705 (NEED_MEM_INSERT): New macro.
4706 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4707 Remove one incorrect comment and fix another.

4719 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
4720 [REL_ALLOC]: ... to here, to check interface.
4721 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4722 Remove decls. This fixes an "It stinks!".
4724 * alloc.c (which_symbols): Fix alignment issue / type clash.
4726 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4728 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4745 Remove definition of GC_MARK_STACK, since the default now works.
4746 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4747 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4748 no longer the default.
4749 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4751 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4753 * lread.c (lisp_file_lexically_bound_p):

4774 2012-04-11 Daniel Colascione <dancol@dancol.org>
4776 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4777 against is gone. It's better to use vfork now so that when Cygwin
4778 gains a new, working vfork, we use it automatically (bug#10398).
4780 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4801 being loaded (bug#10424).
4803 2012-04-09 Glenn Morris <rgm@gnu.org>
4805 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4806 not just in the obarray, before snarfing them. (Bug#11036)

4818 Add convenience `GNUTLS_LOG2i' macro.
4820 * gnutls.c (gnutls_log_function2i): Convenience log function.
4821 (emacs_gnutls_read): Use new log functions,
4822 `gnutls_handshakes_tried' process member, and
4823 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4824 attempts per process (connection).

4833 * minibuf.c (Fread_variable): Callers changed.
4835 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4837 * xdisp.c (set_cursor_from_row): If the display string appears in
4838 the buffer at position that is closer to point than the position
4839 after the display string, display the cursor on the first glyph of
4840 the display string. Fixes cursor display when a 'display' text
4841 property immediately follows invisible text. (Bug#11094)
4843 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4845 composite.c: use 'double' consistently
4846 * composite.c (get_composition_id): Use 'double' consistently
4847 instead of converting 'float' to 'double' and vice versa; this is
4848 easier to understand and avoids a GCC warning.
4850 2012-04-09 Glenn Morris <rgm@gnu.org>
4852 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4853 preparation for dumping it with emacs. (Bug#4789)

4875 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4876 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4877 objects, as mark_maybe_pointer will catch them otherwise.
4878 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4879 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4881 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4883 Fix typo that broke non-Windows builds.
4884 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

4897 [!WINDOWSNT]: New macros.
4898 (init_libxml2_functions, libxml2_loaded_p): New functions.
4899 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4900 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4901 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4902 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4904 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4905 Call init_libxml2_functions before calling libxml2 functions.
4906 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4908 * emacs.c: Don't include libxml/parser.h.
4909 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4910 xmlCleanupParser directly.
4912 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4914 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4916 * indent.c (Fvertical_motion): If there is a display string at
4917 point, use it.vpos to compute how many lines to backtrack after

4922 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4923 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4924 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4925 macros related to unification of CJK characters. For the details,
4926 see the discussion following the message here:
4927 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4929 2012-04-04 Chong Yidong <cyd@gnu.org>
4931 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4933 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4935 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

4938 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4940 * w32menu.c (is_simple_dialog): Properly check lisp types.
4943 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4945 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4946 position we get to after a call to move_it_to fails the
4947 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4948 only if we wind up in a string from display property. (Bug#11063)
4950 * window.c (Fdelete_other_windows_internal): Invalidate the row
4951 and column information about mouse highlight, so that redisplay
4952 restores it after reallocating the glyph matrices. (Bug#7464)
4954 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4955 string comes from a `display' text property, use the buffer
4956 position of that property as if we actually saw that position in
4958 (move_it_by_lines): Remove the assertion that
4959 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4960 violated when there's a before-string at the beginning of a line.
4963 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4965 * xdisp.c (append_space_for_newline): If the default face was
4966 remapped, use the remapped face for the appended newline.
4967 (extend_face_to_end_of_line): Use the remapped default face for
4968 extending the face to the end of the line.
4969 (display_line): Call extend_face_to_end_of_line when the default
4970 face was remapped. (Bug#11068)
4972 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4974 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

4985 2012-03-26 Kenichi Handa <handa@m17n.org>
4987 * dispextern.h (struct glyph): Fix previous change. Change the
4988 bit length of glyphless.ch to 25 (Bug#11082).
4990 2012-03-26 Chong Yidong <cyd@gnu.org>
4992 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4993 (command_loop_1): Use it; inhibit selection update for
4994 handle-select-window too (Bug#8996).
4996 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4998 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5000 2012-03-25 Kenichi Handa <handa@m17n.org>
5002 * dispextern.h (struct glyph): Change the bit length of
5003 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5005 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5007 * s/ms-w32.h (tzname): Include time.h before redirecting to
5008 _tzname. Fixes the MSVC build. (Bug#9960)
5010 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5012 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5015 * xterm.c (XTread_socket): Only modify handling_signal if
5016 !SYNC_INPUT. (Bug#11080)
5018 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5020 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5021 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5022 when fetching a multibyte character consumes more bytes than
5023 CHAR_BYTES returns, due to unification of CJK characters in
5024 string_char. (Bug#11073)
5026 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5028 * process.c (wait_reading_process_output): Handle pty disconnect
5029 by refraining from sending oneself a SIGCHLD (bug#10933).
5031 2012-03-22 Chong Yidong <cyd@gnu.org>

5044 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5046 * w32proc.c (Fw32_set_console_codepage)
5047 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5052 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5053 to reflect default non-nil value of redisplay-dont-pause.
5055 2012-03-19 Kenichi Handa <handa@m17n.org>

5058 it fit in a valid range (Bug#11003).
5060 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5062 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5063 that is not from display property, accept the row as a "cursor
5064 row" if one of the string's character has a non-nil `cursor'
5065 property. Fixes cursor positioning when there are newlines in
5066 overlay strings, e.g. in icomplete.el. (Bug#11035)
5068 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5070 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5072 2012-03-12 Chong Yidong <cyd@gnu.org>
5074 * eval.c (inhibit_lisp_code): Rename from
5075 inhibit_window_configuration_change_hook; move from window.c.
5077 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5078 * window.c (run_window_configuration_change_hook)
5079 (syms_of_window): Callers changed.
5081 2012-03-11 Chong Yidong <cyd@gnu.org>

5094 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5096 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5098 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5099 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5102 2012-03-03 Glenn Morris <rgm@gnu.org>
5104 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5106 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5108 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5109 position past the first glyph_row that ends at ZV. (Bug#10902)
5110 (redisplay_window, next_element_from_string): Fix typos in
5112 (redisplay_window): Pass to move_it_vertically the margin in
5113 pixels, not in screen lines.
5115 2012-03-02 Glenn Morris <rgm@gnu.org>
5117 * buffer.c (buffer-list-update-hook): Doc fix.
5119 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5121 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5122 push_it before setting up the iterator for the first overlay
5123 string, even if we have an empty string loaded.
5124 (next_overlay_string): If there's an empty string on the iterator
5125 stack, pop the stack. (Bug#10903)
5127 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5129 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5130 Suggested by Stefan Monnier in
5131 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5132 * alloc.c (widen_to_Lisp_Object): New static function.
5133 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5134 and widening them to Lisp_Objects. This would work even if
5135 USE_LSB_TAG is defined and wide integers are used, which might
5136 happen in a future version of Emacs.
5138 2012-02-25 Chong Yidong <cyd@gnu.org>
5140 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5143 * xselect.c (Fx_selection_exists_p): Doc fix.
5144 (x_clipboard_manager_save_all): Print an informative message
5145 before saving to clipboard manager.
5147 2012-02-24 Chong Yidong <cyd@gnu.org>
5149 * keyboard.c (process_special_events): Handle all X selection
5150 requests in kbd_buffer, not just the next one (Bug#8869).
5152 2012-02-23 Chong Yidong <cyd@gnu.org>
5154 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5155 call when setting menu-bar-lines and tool-bar-lines parameters.
5156 (unwind_create_frame_1): New helper function.
5158 * window.c (inhibit_window_configuration_change_hook): New var.
5159 (run_window_configuration_change_hook): Obey it.
5160 (syms_of_window): Initialize it.
5162 2012-02-22 Chong Yidong <cyd@gnu.org>
5164 * xterm.c (x_draw_image_relief): Add missing type check for
5165 Vtool_bar_button_margin (Bug#10743).

5169 * fileio.c (Vfile_name_handler_alist): Doc fix.
5171 * buffer.c (Fget_file_buffer): Protect against invalid file
5172 handler return value.
5174 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5176 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5177 when computing $valmask.
5179 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5180 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5181 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5182 It's useless in that case, and it can cause problems on hosts
5183 that allocate halves of EMACS_INT values separately.
5184 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5185 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5186 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5187 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5188 it avoids undefined behavior on hosts where shifting right by more
5189 than the word width has undefined behavior.
5191 2012-02-19 Chong Yidong <cyd@gnu.org>
5193 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5194 (Funhandled_file_name_directory, Ffile_name_as_directory)
5195 (Fdirectory_file_name, Fexpand_file_name)
5196 (Fsubstitute_in_file_name): Protect against invalid file handler
5197 return values (Bug#10845).
5199 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5201 * .gdbinit (pitx): Fix incorrect references to fields of the
5204 2012-02-17 Chong Yidong <cyd@gnu.org>

5211 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5213 2012-02-15 Chong Yidong <cyd@gnu.org>
5215 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5216 marked as special. Also, starting docstrings with * is obsolete.
5218 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5220 * gnutls.c (emacs_gnutls_write): Fix last change.
5222 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5231 2012-02-12 Chong Yidong <cyd@gnu.org>
5233 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5234 as that creates a dangerous corner case.
5236 * window.c (Fdelete_window_internal): Invalidate the mouse
5237 highlight (Bug#9904).
5239 2012-02-12 Glenn Morris <rgm@gnu.org>
5241 * xselect.c (Fx_own_selection_internal)
5242 (Fx_get_selection_internal, Fx_disown_selection_internal)
5243 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5244 * nsselect.m (Fx_own_selection_internal)
5245 (Fx_disown_selection_internal, Fx_selection_exists_p)
5246 (Fx_selection_owner_p, Fx_get_selection_internal):
5247 Sync docs and argument specs with the xselect.c versions.
5249 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5251 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5253 2012-02-11 Eli Zaretskii <eliz@gnu.org>

5269 2012-02-07 Chong Yidong <cyd@gnu.org>
5271 * buffer.c (Fbuffer_local_variables)
5272 (buffer_lisp_local_variables): Handle unbound vars correctly;
5273 don't let Qunbound leak into Lisp.
5275 2012-02-07 Glenn Morris <rgm@gnu.org>
5277 * image.c (Fimagemagick_types): Doc fix.
5279 * image.c (imagemagick-render-type): Change it from a lisp object
5280 to an integer. Move the doc here from the lisp manual.

5283 2012-02-06 Chong Yidong <cyd@gnu.org>
5285 * doc.c (store_function_docstring): Avoid applying docstring of
5286 alias to base function (Bug#2603).
5288 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5290 * .gdbinit (pp1, pv1): Remove redundant defines.
5293 2012-02-04 Chong Yidong <cyd@gnu.org>
5295 * nsterm.m: Declare a global (Bug#10694).
5297 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5299 * w32.c (get_emacs_configuration_options):
5300 Include --enable-checking, if specified, in the return value.
5302 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5304 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5305 after rounding frame sizes. (Bug#9723)
5307 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5309 * keyboard.c (adjust_point_for_property): Don't position point
5310 before BEGV. (Bug#10696)
5312 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5314 Handle overflow when computing char display width (Bug#9496).
5315 * character.c (char_width): Return EMACS_INT, not int.
5316 (char_width, c_string_width): Check for overflow when
5317 computing the width; this is possible now that individual
5318 characters can have unbounded width. Problem introduced
5319 by merge from Emacs 23 on 2012-01-19.
5321 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5323 * dbusbind.c (Fdbus_register_method): Mention the return value

5336 2012-02-02 Kenichi Handa <handa@m17n.org>
5338 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5339 0, do not call append_composite_glyph.
5341 2012-02-02 Kenichi Handa <handa@m17n.org>
5343 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5345 (x_produce_glyphs): If the component of a composition is a null
5346 string, set it->pixel_width to 1 to avoid zero-width glyph.
5348 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5350 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5351 first 2 arguments are identical. This makes inserting large
5352 output from a subprocess an order of magnitude faster on
5353 MS-Windows, where all sbrk'ed memory is always contiguous.

5883 * xdisp.c (redisplay_window): If cursor row is not fully visible
5884 after recentering, and scroll-conservatively is set to a large
5885 number, scroll window by a few more lines to make the cursor fully
5886 visible and out of scroll-margin. (Bug#10105)
5887 (start_display): Don't move to the next line if the display should
5888 start at a newline that is part of a display vector or an overlay

5972 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5973 is set, removing the need for VIRT_ADDRESS_VARIES.
5974 (PURE_P): Use a more-efficient implementation that needs just one
5975 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5976 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5977 to 4 (xorl, subq, cmpq, setbe).
5978 * alloc.c (pure): Always extern now, since that's the
5979 VIRT_ADDR_VARIES behavior.
5980 (PURE_POINTER_P): Use a single comparison, not two, for
5981 consistency with the new puresize.h.
5982 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

5989 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5990 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5991 behave as if the cursor position were at the window margin.
5993 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5994 and the cursor position is out of bounds, behave as if the cursor
5995 position were at the window margin. (Bug#10075)
5997 2011-11-18 Chong Yidong <cyd@gnu.org>
5999 * window.c (Fwindow_combination_limit): Make first argument

6022 (compute_line_metrics): Call row_hash, instead of computing the
6025 * dispnew.c (verify_row_hash): Call row_hash for computing the
6026 hash code of a row, instead of duplicating code from xdisp.c.
6028 * dispextern.h (row_hash): Add prototype.
6030 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6059 (Fset_window_configuration, save_window_save): Rename all
6060 occurrences of window_nest to window_combination_limit.
6062 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6064 * image.c (imagemagick_load_image): Fix typo.
6066 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6068 * xdisp.c (display_line): Move the call to
6069 highlight_trailing_whitespace before the call to
6070 compute_line_metrics, since the latter needs to see the final
6071 faces of all the glyphs to compute ROW's hash value.
6072 Fixes assertion violations in row_equal_p. (Bug#10035)
6074 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6076 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6081 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6082 with user-defined heap size. Bump the default size of the temacs
6083 heap to 27MB, to avoid memory warning when running temacs.

6133 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6135 Avoid some portability problems by eschewing 'extern inline' functions.
6136 The trivial performance wins aren't worth the portability hassles; see
6137 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6139 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6141 (window_box_right, window_box_right_offset): Undo previous change,
6142 by removing the "extern"s.
6143 * intervals.c (adjust_intervals_for_insertion)
6144 (adjust_intervals_for_deletion): Undo previous change,
6145 making these static again.
6146 (offset_intervals, temp_set_point_both, temp_set_point)
6147 (copy_intervals_to_string): No longer inline.
6148 * xdisp.c (window_text_bottom_y, window_box_width)

6214 (window_box_right, window_box_right_offset): Declare extern.
6215 Otherwise, these inline functions do not conform to C99 and
6216 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6217 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6218 * intervals.c (adjust_intervals_for_insertion)
6219 (adjust_intervals_for_deletion): Now extern, because otherwise the

6221 (static_offset_intervals): Remove.
6222 (offset_intervals): Rewrite using the old contents of
6223 static_offset_intervals. The old version didn't conform to C99
6224 because an extern inline function contained a reference to an
6225 identifier with static linkage.

6247 (Fwindow_vscroll): Doc fix.
6248 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6249 argument, since it makes no sense to pass a live window and for
6250 consistency with window-child.

6278 (unwind_create_frame): New function (Bug#9943).
6279 (Fx_create_frame): Restructure code to be more similar to the one in
6280 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6281 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6282 Move terminal->reference_count++ just before making the frame official

6286 (x_destroy_window): Move code to x_free_frame_resources.
6288 * xfns.c (unwind_create_frame): Fix comment.

6290 Move terminal->reference_count++ just before making the frame
6291 official. Move initialization of image_cache_refcount and
6292 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

6327 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
6329 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6331 * xdisp.c (note_mouse_highlight): If either of
6332 previous/next-single-property-change returns nil, treat that as
6333 the beginning or the end of the buffer. (Bug#9955)
6335 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6337 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
6338 label is not null (Bug#9951).

6349 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
6351 * w32fns.c (unwind_create_frame): If needed, free the glyph
6352 matrices of the partially constructed frame. (Bug#9943)
6353 * xfns.c (unwind_create_frame): Likewise.
6355 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6357 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6358 Don't stop backward scan on the continuation glyph, even though
6359 its CHARPOS is positive.
6360 (mouse_face_from_buffer_pos, note_mouse_highlight):
6361 Rename cover_string to disp_string.
6363 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6365 * window.c (temp_output_buffer_show): Don't use
6366 Vtemp_buffer_show_specifiers.
6367 (Vtemp_buffer_show_specifiers): Remove unused variable.
6369 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6371 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6372 past the beginning of the current glyph matrix.
6374 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6376 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6377 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6378 HAVE_GTK3 (Bug#9869).
6380 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6381 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6383 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6385 * xterm.c: Declare x_handle_net_wm_state to return int.
6386 (handle_one_xevent): Check if we are iconified but don't have
6387 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).

6394 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6396 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6397 so that this new function doesn't get optimized away by a
6398 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6400 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6402 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6404 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6406 Fix the `xbytecode' command.
6407 * .gdbinit (xprintbytestr): New command.
6408 (xwhichsymbols): Rename from `which'; all callers changed.
6409 (xbytecode): Print the byte-code string as well.
6411 2011-10-29 Kim Storm <storm@cua.dk>
6413 * alloc.c (which_symbols): New function.
6415 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6417 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6420 2011-10-29 Glenn Morris <rgm@gnu.org>
6422 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6423 Not clear what it was for, and it causes various bugs. (Bug#9839)
6425 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6427 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6428 possible random value that matches one of those tested as
6429 condition to clear the mouse face.
6431 2011-10-28 Chong Yidong <cyd@gnu.org>
6433 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6435 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6437 * window.c (make_window): Initialize phys_cursor_on_p.
6439 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6441 * lisp.h (struct Lisp_Symbol): Update comments.
6443 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6445 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6447 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6449 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6450 <oslsachem@gmail.com> for helping to debug this.
6452 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6453 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6454 (g_b_init_get_glyph_outline_w): New static variables.
6455 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6456 (GetGlyphOutlineW_Proc): New typedefs.
6457 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6458 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6460 (w32font_open_internal, compute_metrics):
6461 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6462 instead of calling the "wide" APIs directly.
6464 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6466 * w32.h (syms_of_w32font): Add prototype.
6468 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6470 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6471 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6472 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6475 2011-10-27 Chong Yidong <cyd@gnu.org>
6477 * process.c (make_process): Set gnutls_state to NULL.
6479 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6480 non-NULL, regardless of GNUTLS_INITSTAGE.
6481 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6482 an error. Set process slots as soon as we allocate them.
6484 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6486 2011-10-27 Chong Yidong <cyd@gnu.org>

6492 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6493 (deactivate_process): Call emacs_gnutls_deinit.
6495 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6500 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6502 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6504 * w32fns.c (w32_default_color_map): New function,
6505 extracted from Fw32_default_color_map.
6506 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6508 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6510 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6512 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6514 * keyboard.c (test_undefined): New function (bug#9751).
6515 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6517 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6519 * sysdep.c (init_sys_modes): Fix the check for the controlling
6520 terminal (Bug#6649).
6522 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6524 * dispextern.h (struct bidi_it): New member next_en_type.
6526 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6527 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6528 current character, check also for next_en_type being WEAK_EN.
6529 (bidi_resolve_weak): Don't enter the expensive loop if the current
6530 position is before next_en_pos. Record the bidi type of the first
6531 non-ET, non-BN character we find, in addition to its position.
6532 (bidi_level_of_next_char): Invalidate next_en_type when
6533 next_en_pos is over-stepped.
6535 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6537 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6538 * editfns.c: Rewrite current-time-zone so that it invokes
6539 the equivalent of (format-time-string "%Z") to get the time zone name.
6540 This fixes a bug when the time zone name contains characters that
6541 need converting from the system time locale to Emacs internal format.
6542 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6543 that patch fixed format-time-string to do the conversion, but
6544 I forgot to fix current-time-zone.
6545 (format_time_string): New function, containing most of
6546 what Fformat_time_string used to contain.
6547 (Fformat_time_string): Rewrite in terms of format_time_string.
6548 This doesn't change this function's behavior.
6549 (current-time-zone): Rewrite to use format_time_string.
6550 This fixes the bug reported by Michael Schierl in
6551 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6552 Jason Rumney's 2007-06-07 change worked around this bug, but
6554 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6556 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6558 * xdisp.c (start_display): If the character at POS is displayed
6559 via a display vector, reset IT->current.dpvec_index to zero.
6560 (try_window_reusing_current_matrix): If a line ends in a display
6561 vector or the next line starts in a display vector, continue
6562 redrawing the window even though the character position of
6563 start_row was reached.
6566 2011-10-18 Chong Yidong <cyd@gnu.org>
6568 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6569 with nobreak-char-display too.
6571 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6573 Fix part 3 of bug#9771.
6574 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6575 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6576 non-neutral characters if the current character is a paragraph
6577 separator (a.k.a. Newline). This avoids running the same
6578 expensive loop twice, once when we consume the preceding newline
6579 and the other time when the line actually needs to be displayed.
6580 Avoid the loop when we see neutrals on the base embedding level
6581 following a character whose directionality is the same as the
6582 paragraph's. This avoids running the expensive loop when a line
6583 ends in a long sequence of neutrals, like control characters.
6584 Add assertion against STRONG_AL type. Slightly rearrange code
6585 that determines the type of a neutral given the first non-neutral
6587 (bidi_level_of_next_char): Set next_en_pos to zero when
6588 invalidating its info.
6590 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6592 * xdisp.c (push_display_prop): Determine whether to record string
6593 or buffer position by IT->string, not by IT->method. Allow
6594 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6595 (move_it_vertically_backward): Don't look for character position
6596 immediately after the newline when in a continuation line.
6599 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6601 * window.c (coordinates_in_window): Rewrite and delabelize
6602 vertical border check. (Bug#5357) (Bug#9618)
6604 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6606 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6607 errors in XSetWindowBorder (bug#9310).
6609 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6611 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6612 avoid crash when xmalloc overrun checking is enabled.
6614 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6616 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6617 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6618 cursor motion with <left> and <right> arrow keys.
6620 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6621 some callers set that themselves.
6623 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6625 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6626 display string and the previous row comes from the same string and
6627 is empty. (Bug#9739) (Bug#9738)
6629 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6631 * doc.c (get_doc_string): Encode file name (bug#9735).
6633 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6635 * bidi.c (bidi_level_of_next_char):
6636 * xdisp.c (get_visually_first_element): Remove old incorrect
6637 comments regarding the Unicode Line Separator character.
6639 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6641 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6643 * alloc.c (Fgc_status): Do not access beyond zombies array
6644 boundary if nzombies > MAX_ZOMBIES.
6645 * alloc.c (dump_zombies): Add missing format specifier.
6647 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6649 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6650 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6652 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6653 Some packages use them to denote characters with modifiers.
6655 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6657 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6658 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6659 matching a pp-number. Rename parameter var to var1.
6661 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6663 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6665 2011-10-08 Glenn Morris <rgm@gnu.org>
6667 * callint.c (Fcall_interactively): Give a more explicit error for the
6668 'c' case with a non-character input. (Bug#8479)
6670 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6672 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6674 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6675 lines that are hscrolled on the left.
6677 * dispnew.c (buffer_posn_from_coords): Account for a possible
6678 presence of header-line. (Bug#4426)
6680 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6682 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6683 Don't advertise functionality which we discourage or doesn't work.
6685 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6687 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6688 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6689 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6690 this makes Emacs dump core during garbage collection on rare
6691 occasions. sizeof is obviously inferior to offsetof here, so
6692 stick with offsetof.
6693 (GC_POINTER_ALIGNMENT): New macro.
6694 (mark_memory): Omit 3rd (offset) arg; caller changed.
6695 Don't assume EMACS_INT alignment is the same as pointer alignment.
6697 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6699 * keyboard.c (read_key_sequence_remapped): New var.
6700 (read_key_sequence): Compute remapping in the right buffer.
6701 (command_loop_1): Use read_key_sequence's remapping directly.
6703 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6705 * dired.c (file_name_completion): Don't expand file name.
6706 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6707 before checking file name handler.
6709 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6710 they've been requested explicitly (bug#9591).
6712 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6714 * keymap.c (Fsingle_key_description): Use make_specified_string
6715 instead of build_string to build string from push_key_description.
6718 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6720 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6721 This fixes a Y2038 bug on 64-bit hosts.
6722 * buffer.c (reset_buffer):
6723 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6724 (Fclear_buffer_auto_save_failure):
6725 Use 0, not -1, to represent an unset failure time, since time_t
6726 might not be signed.
6728 Remove dependency on glibc malloc internals.
6729 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6730 Move back here from lisp.h, but with their new implementations.
6731 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6732 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6733 * charset.c (charset_table_init): New static var.
6734 (syms_of_charset): Use it instead of xmalloc. This removes a
6735 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6736 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6737 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6738 Move back to alloc.c.
6739 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6740 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6742 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6744 * nsterm.m (windowDidResize): Call x_set_window_size only when
6745 ns_in_resize is true. Otherwise set pixelwidth/height and
6746 call change_frame_size (Bug#9628).
6748 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6750 Port --enable-checking=all to Fedora 14 x86-64.
6751 * charset.c (syms_of_charset): Also account for glibc malloc's
6752 internal overhead when calculating the initial malloc maximum.
6754 Port --enable-checking=all to Fedora 14 x86.
6755 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6757 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6758 (overrun_check_realloc, overrun_check_free):
6759 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6760 That way, xmalloc returns a properly-aligned pointer even if
6761 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6762 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6763 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6764 into account when calculating the initial malloc maximum.
6765 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6766 Move here from alloc.c, so that charset.c can use it too.
6767 Properly align; the old code wasn't right for common 32-bit hosts
6768 when configured with --enable-checking=all.
6769 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6770 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6772 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6774 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6777 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6779 * xdisp.c (compute_display_string_end): If there's no display
6780 string at CHARPOS, return -1.
6782 * bidi.c (bidi_fetch_char): When compute_display_string_end
6783 returns a negative value, treat the character as a normal
6784 character not covered by a display string. (Bug#9624)
6786 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6788 * lread.c (Fread_from_string): Fix typo in docstring.
6790 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6792 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6793 newline, reseat the iterator instead of bidi-iterating there one
6794 character at a time. (Bug#9610)
6795 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6796 TO_CHARPOS if the bidi iterator is at base embedding level.
6798 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6800 * lread.c (readevalloop): Use correct code for NBSP.
6801 (read1): Likewise. (Bug#9608)
6803 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6805 * dbusbind.c (Fdbus_register_signal): When service is not
6806 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6808 2011-09-25 Glenn Morris <rgm@gnu.org>
6810 * buffer.c (truncate-lines): Doc fix.
6812 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

6827 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6829 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6830 Default value is now t. Doc fix.
6832 * indent.c (Fvertical_motion): Compute and apply the overshoot
6833 logic when moving up, not only when moving down. Fix the
6834 confusing name and values of the it_overshoot_expected variable;
6835 logic changes accordingly. (Bug#9254) (Bug#9549)
6837 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6838 CHARPOS is covered by a display string which includes newlines.
6839 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6840 is covered by a display string with embedded newlines.
6842 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6844 * dbusbind.c (Fdbus_register_signal): Add match rule to
6845 Vdbus_registered_objects_table. (Bug#9581)
6846 (Fdbus_register_method, Vdbus_registered_objects_table):
6849 2011-09-24 Jim Meyering <meyering@redhat.com>
6851 do not ignore write error for any output size
6852 The previous change was incomplete.
6853 While it makes emacs --batch detect the vast majority of stdout
6854 write failures, errors were still ignored whenever the output size is
6855 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6856 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6857 && echo FAIL: ignored write error
6858 FAIL: ignored write error
6859 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6860 && echo FAIL: ignored write error
6861 FAIL: ignored write error
6862 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6864 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6866 * emacs.c (Fkill_emacs): In noninteractive mode exit
6867 non-successfully if a write error occurred on stdout. (Bug#9574)
6869 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6871 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6874 * dispextern.h (struct it): Update the comment documenting what
6877 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6879 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6880 a display string, extend search for cursor position to end of row.
6881 (find_row_edges): If the row ends in a newline from a display
6882 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6883 Handle the case of a display string with multiple newlines.
6884 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6885 non-empty line. Fixes confusing cursor motion with arrow keys at
6886 the beginning of a line that starts with whitespace.
6888 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6890 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6893 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6895 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6898 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6900 * xdisp.c (display_line): Record maximum and minimum buffer
6901 positions even if no glyphs were produced (e.g., by a zero-width
6902 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6903 buffer positions that will be removed from the glyph row because
6905 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6906 column is beyond frame width: don't subtract 1 "pixel" when
6907 computing width of the stretch.
6908 (reseat_at_next_visible_line_start): Undo the change made on
6909 2011-09-17 that saved paragraph information and restored it after
6910 the call to `reseat'. (Bug#9545)
6912 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6914 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6915 and turn window cursor on if cleared (Bug#9415).

6919 * search.c (boyer_moore): Take unibyte characters from pattern
6920 literally. (Bug#9458)
6922 2011-09-18 Eli Zaretskii <eliz@gnu.org>

6926 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6928 Fix minor problem found by static checking.
6929 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6930 initialized, to pacify gcc -Wuninitialized.
6932 * fileio.c: Report proper errno when syscall falls.
6933 (Finsert_file_contents): Save and restore errno,
6934 so that report_file_error outputs the correct diagnostic.
6935 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6937 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6939 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6941 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6943 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6944 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6946 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6948 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6949 about the current paragraph and restore it after the call to reseat.
6951 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6952 (bidi_find_paragraph_start): Search back for paragraph beginning
6953 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6954 (bidi_move_to_visually_next): Only trigger paragraph-related
6955 computations when the last character is a newline or at EOB, not
6956 just any NEUTRAL_B. (Bug#9470)
6958 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6959 truncated lines if point is covered by a display string. (Bug#9524)
6961 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6963 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6964 (cons_to_x_long): New function.
6965 (lisp_data_to_selection_data): Use it. Correct the test for
6966 short-versus-long data; it was negated. Break out of vector
6967 loop, for efficiency, when a long datum is discovered.
6969 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6971 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6973 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6975 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6976 GCC PR/17406) by declaring this function with external scope.
6978 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6980 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6981 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6983 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6985 * editfns.c (Fformat): Correctly handle text properties on "%%".

6995 of TAB characters in a composition.
6997 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6999 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7000 This occurs when processing a multibyte format.
7001 Problem reported by Wolfgang Jenker.
7003 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7005 * xdisp.c (try_cursor_movement): Only check for exact match if
7006 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7008 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7010 Remove unused external symbols.
7011 * dispextern.h (calc_pixel_width_or_height): Remove decl.

7014 * indent.c (check_display_width):
7015 * w32term.c: Fix comment to match code.
7016 * xterm.c, xterm.h (x_catching_errors): Remove.
7018 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7020 * xselect.c: Use signed conversions more consistently (Bug#9498).
7021 (selection_data_to_lisp_data): Assume incoming selection data are
7022 signed integers, not unsigned. This is to be consistent with
7023 outgoing selection data, which was modified to use signed integers
7024 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7025 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7026 expects long, not unsigned long.
7028 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7030 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7031 computation of loop end. Reported by Johan Bockgård
7034 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7036 * frame.c (Fother_visible_frames_p): Function deleted.
7038 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7040 * indent.c (compute_motion): Process display vector front to back
7041 rather than the other way around. (Bug#2496)
7043 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7045 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7047 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7049 * minibuf.c (Fread_from_minibuffer): Doc fix.
7051 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7053 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7054 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7056 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7058 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7059 value for non-existent files.
7061 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7063 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7064 set its "size" to -1. This will set the modtime_size field of
7065 the corresponding buffer to -1, which is what
7066 verify-visited-file-modtime expects for files that do not exist.
7069 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7071 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7073 * lisp.h: ... from here. push_key_description is no longer
7074 defined in keyboard.c, so its declaration should not be in
7075 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7076 logically belongs with push_key_description.
7078 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7080 * buffer.h: Include <sys/types.h> instead of <time.h>.
7081 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7082 Problem reported by Herbert J. Skuhra.
7084 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7086 * xml.c (parse_region): Make the parsing work for
7087 non-comment-starting XML files again (bug#9144).
7089 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7091 * image.c (gif_load): Fix calculation of bottom and right corner.
7094 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7096 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7097 redisplay in small windows.
7099 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7101 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7103 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7105 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7106 Operate on live windows only.
7108 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7110 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7112 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7114 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7115 only under bidi iteration.
7117 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7119 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7121 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7123 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7124 Without this fix, the command to link temacs failed due to an
7125 undefined symbol __builtin_isnan. This is because
7126 /usr/include/iso/math_c99.h #defines isnan(x) to
7127 __builtin_isnan(x), but the bundled gcc, which identifies itself
7128 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7130 * floatfns.c (isnan): #undef, and then #define to a clone of
7132 (Fisnan): Always define, since it's always available now.
7133 (syms_of_floatfns): Always define isnan at the Lisp level.
7135 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7137 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7139 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7141 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7142 The previous code assumed that file offsets (off_t values) fit in
7143 EMACS_INT variables, which is not true on typical 32-bit hosts.
7144 The code messed up by falsely reporting buffer overflow in cases
7145 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7146 when "big" contains more than 2**29 bytes, even though this
7147 inserts just one byte and does not overflow the buffer.
7148 (Finsert_file_contents): Store file offsets as off_t
7149 values, not as EMACS_INT values. Check for overflow when
7150 converting between EMACS_INT and off_t. When checking for
7151 buffer overflow or for overlap, take the offsets into account.
7152 Don't use EMACS_INT for small values where int suffices.
7153 When checking for overlap, fix a typo: ZV was used where
7154 ZV_BYTE was intended.
7155 (Fwrite_region): Don't assume off_t fits into 'long'.
7156 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7158 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7160 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7162 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7164 sprintf-related integer and memory overflow issues (Bug#9412).
7166 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7167 (esprintf, exprintf, evxprintf): New functions.
7168 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7169 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7170 (modify_event_symbol): Do not assume that the length of
7171 name_alist_or_stem is safe to alloca and fits in int.
7172 (Fexecute_extended_command): Likewise for function name and binding.
7173 (Frecursion_depth): Wrap around reliably on integer overflow.
7174 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7175 since some callers pass EMACS_INT values.
7176 (Fsingle_key_description): Don't crash if symbol name contains more
7177 than MAX_ALLOCA bytes.
7178 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7179 (get_minibuffer): Arg is now EMACS_INT, not int.
7180 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7181 (esprintf, exprintf, evxprintf): New decls.
7182 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7184 * dbusbind.c (signature_cat): New function.
7185 (xd_signature, Fdbus_register_signal):
7186 Do not overrun buffer; instead, report string overflow.
7188 * dispnew.c (add_window_display_history): Don't overrun buffer.
7189 Truncate instead; this is OK since it's just a log.
7191 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7192 even if the time zone offset is outlandishly large.
7193 Don't mishandle offset == INT_MIN.
7195 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7196 when creating daemon; the previous buffer-overflow check was incorrect.
7198 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7199 which has the guts of the old verror function.
7201 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7202 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7204 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7205 (font_unparse_xlfd): Don't blindly alloca long strings.
7206 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7207 fits in int, when using sprintf. Use single snprintf to count
7208 length of string rather than counting it via multiple sprintfs;
7209 that's simpler and more reliable.
7210 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7211 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7212 sprintf, in case result does not fit in int.
7214 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7215 (fontset_from_font): Print it.
7217 * frame.c (tty_frame_count): Now printmax_t, not int.
7218 (make_terminal_frame, set_term_frame_name): Print it.
7219 (x_report_frame_params): In X, window IDs are unsigned long,
7220 not signed long, so print them as unsigned.
7221 (validate_x_resource_name): Check for implausibly long names,
7222 and don't assume name length fits in 'int'.
7223 (x_get_resource_string): Don't blindly alloca invocation name;
7224 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7227 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7228 (xg_check_special_colors, xg_set_geometry):
7229 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7231 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7232 Use esprintf, not sprintf, in case result does not fit in int.
7234 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7235 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7236 it as a large positive number.
7237 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7238 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7240 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7241 in case result does not fit in int.
7243 * print.c (float_to_string): Detect width overflow more reliably.
7244 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7245 buffer overrun. Don't assume list length fits in 'int'. Treat
7246 print length of 0 as 0, not as infinity; to be consistent with other
7247 uses of print length in this function. Don't overflow print length
7248 index. Don't assume hash table size fits in 'long', or that
7249 vectorlike size fits in 'unsigned long'.
7251 * process.c (make_process): Use printmax_t, not int, to format
7252 process-name gensyms.
7254 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7256 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7257 to avoid potential buffer overrun.
7259 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7260 if X resource line is longer than 512 bytes.
7262 * xfns.c (x_window): Make sprintf buffer a bit bigger
7263 to avoid potential buffer overrun.
7265 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7267 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7269 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7271 Integer overflow fixes for scrolling, etc.
7272 Without these, Emacs silently mishandles large integers sometimes.
7273 For example, "C-u 4294967297 M-x recenter" was treated as if
7274 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7276 * xdisp.c (try_window_id): Check Emacs fixnum range before
7277 converting to 'int'.
7279 * window.c (window_scroll_line_based, Frecenter):
7280 Check that an Emacs fixnum is in range before assigning it to 'int'.
7281 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7282 values converted from Emacs fixnums.
7283 (Frecenter): Don't wrap around a line count if it is out of 'int'
7284 range; instead, treat it as an extreme value.
7285 (Fset_window_configuration, compare_window_configurations):
7286 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7288 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7289 that can exceed INT_MAX. Check that EMACS_INT value is in range
7290 before assigning it to the (possibly-narrower) index.
7291 (match_limit): Don't assume that a fixnum can fit in 'int'.
7293 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7296 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7297 (Fvertical_motion): Don't wrap around LINES values that don't fit
7298 in 'int'. Instead, treat them as extreme values. This is good
7299 enough for windows, which can't have more than INT_MAX lines anyway.
7301 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7303 * Require libxml/parser.h to avoid compilation warning.
7305 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7307 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7308 since this reportedly can destroy thread storage.
7310 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7312 * syntax.c (find_defun_start): Update all cache variables if
7313 exiting early (Bug#9401).
7315 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7317 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7319 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7320 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7321 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7323 * term.c (tty_append_glyph): New function.
7324 (produce_stretch_glyph): Static function and its prototype deleted.
7326 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7329 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7331 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7332 when checking :margin (Bug#9390).
7333 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7334 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7335 so that the name doesn't mislead. All uses changed.
7337 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7339 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7342 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7344 * xdisp.c (move_it_to): Don't bail out early when reaching
7345 position beyond to_charpos, if we are scanning backwards.
7346 (move_it_vertically_backward): When DY == 0, make sure we get to
7347 the first character in the line after the newline.
7349 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7351 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7352 (ccl_driver): Do not generate an out-of-range pointer.
7353 (Fccl_execute_on_string): Remove unnecessary check for
7354 integer overflow, noted by Stefan Monnier in
7355 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7356 Remove a FIXME that didn't need fixing.
7357 Simplify the newly-introduced buffer reallocation code.
7359 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7361 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7363 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7365 Integer and memory overflow issues (Bug#9196).
7367 * doc.c (get_doc_string): Rework so that
7368 get_doc_string_buffer_size is the actual buffer size, rather than
7369 being 1 less than the actual buffer size; this makes xpalloc more
7372 * image.c (x_allocate_bitmap_record, cache_image):
7373 * xselect.c (Fx_register_dnd_atom):
7374 Simplify previous changes by using xpalloc.
7376 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7377 since either will do and ptrdiff_t is convenient with xpalloc.
7379 * charset.c (charset_table_size)
7380 (struct charset_sort_data.priority): Now ptrdiff_t.
7381 (charset_compare): Don't overflow if priorities differ greatly.
7382 (Fsort_charsets): Don't assume list length fits in int.
7383 Check for size-calculation overflow when allocating sort data.
7384 (syms_of_charset): Allocate an initial charset table that is
7385 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7387 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7389 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7390 The actual value is always <= INT_MAX, and leaving it unsigned made
7391 overflow checking harder.
7393 * dispextern.h (struct glyph_matrix.rows_allocated)
7394 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7395 with xpalloc. The values are still always <= INT_MAX.
7397 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7399 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7400 (SAFE_NALLOCA): New macro.
7402 * region-cache.c (struct boundary.pos, find_cache_boundary)
7403 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7404 (set_cache_region, invalidate_region_cache)
7405 (revalidate_region_cache, know_region_cache, region_cache_forward)
7406 (region_cache_backward, pp_cache):
7407 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7408 so that ptrdiff_t * can be passed to xpalloc.
7409 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7410 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7411 (pp_cache): Don't assume cache_len fits in int.
7412 * region-cache.h: Adjust extern decls to match.
7414 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7415 EMACS_INT, since either will do, for xpalloc.
7417 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7418 (xnmalloc, xnrealloc, xpalloc): New functions.
7420 * bidi.c (bidi_shelve_header_size): New constant.
7421 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7422 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7424 * bidi.c (bidi_cache_shrink):
7425 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7427 Don't update size of array until after memory allocation succeeds,
7428 because xmalloc/xrealloc may not return.
7429 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7430 now that we have proper integer overflow checking.
7431 (record_overlay_string, overlay_strings): Catch overflows when
7432 calculating size of overlay_str_buf.
7434 * callproc.c (Fcall_process): Check for size overflow when
7435 calculating size of args2.
7436 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7437 Normally we prefer signed values, but sticking with ptrdiff_t would
7438 require adding more-complicated checks.
7440 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7441 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7442 Redo buffer-overflow calculations to avoid integer overflow.
7443 Add a FIXME comment where memory seems to be over-allocated.
7445 * character.c (Fstring): Check for size-calculation overflow.
7447 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7448 unnecessary integer overflow. Check for size overflow.
7449 (encode_coding_object): Don't update size until xmalloc succeeds.
7451 * composite.c (get_composition_id): Check for overflow in glyph
7452 length calculations.
7454 Integer and memory overflow fixes for display code.
7455 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7456 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7457 (scrolling_window): Check for overflow in size calculations.
7458 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7469 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7470 (get_doc_string): Check for size calculation overflow.
7471 Don't update size until allocation succeeds.
7472 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7473 EMACS_INT, where ptrdiff_t will do.
7474 (Fsubstitute_command_keys): Check for string overflow.
7476 * editfns.c (set_time_zone_rule): Don't assume environment length
7478 (message_length): Now ptrdiff_t, not int.
7479 (Fmessage_box): Don't update size until allocation succeeds.
7480 Don't assume message length fits in int.
7481 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7483 * emacs.c (main): Do not reallocate argv, since there is a null at
7484 the end that can be overwritten, and this way there's no need to
7485 worry about size-calculation overflow.
7486 (sort_args): Check for size-calculation overflow.
7488 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7490 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7492 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7493 (x_set_scroll_bar_width, x_figure_window_size):
7494 Check for integer overflow.
7495 (x_set_alpha): Do not assume XINT fits in int.
7497 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7498 This is for the members text_lines, text_cols, total_lines, total_cols,
7499 where the system imposes an 'int' limit.
7501 * fringe.c (Fdefine_fringe_bitmap):
7502 Don't update size until alloc works.
7504 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7505 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7507 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7508 Check for size-calculation overflow.
7509 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7510 do, as we prefer signed integers.
7511 (id_to_widget.max_size, id_to_widget.used)
7512 (xg_store_widget_in_map, xg_remove_widget_from_map)
7513 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7514 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7515 Use and return ptrdiff_t, not int.
7516 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7517 * gtkutil.h: Change prototypes to match the above.
7519 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7520 are duplicate now that they've been promoted to lisp.h.
7521 (x_allocate_bitmap_record, x_alloc_image_color)
7522 (make_image_cache, cache_image, xpm_load):
7523 Don't update size until alloc is done.

7533 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7534 Use ptrdiff_t, not int, to count maps.
7535 (read_char_minibuf_menu_prompt): Check for overflow in size
7536 calculations. Don't update size until allocation succeeds.

7548 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7550 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7551 Now ptrdiff_t, not int.
7552 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

7563 * search.c (Freplace_match): Check for size calculation overflow.
7564 (Fset_match_data): Don't assume list lengths fit in 'int'.
7566 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7567 for command line length. Do not attempt to address one before the
7568 beginning of an array, as that's not portable.

7571 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7573 (encode_terminal_code, calculate_costs): Check for size
7574 calculation overflow.

7576 table lengths and related sizes. Don't update size until alloc
7577 done. Redo calculations to avoid overflow.
7578 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7580 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7596 Use ptrdiff_t, not int, for sizes.
7597 (Finternal_make_lisp_face, cache_face):
7598 Check for size calculation overflow.
7599 (cache_face): Treat size calculation overflows as if they were
7600 memory exhaustion (the usual treatment), rather than aborting.
7602 * xfns.c (x_encode_text, x_set_name_internal)
7603 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7604 sizes, since they can exceed INT_MAX in size. Check for size

7608 (xg_select): Check for size calculation overflow.
7609 Don't update size until alloc done.
7611 * xrdb.c (get_environ_db): Don't assume path length fits in int,

7614 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7615 (X_LONG_MIN): New macros.
7616 Use them to make the following changes clearer.
7617 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7618 This change doesn't affect the value now, but it may help remind
7619 future maintainers not to raise the value too much later.
7620 (SELECTION_QUANTUM): Remove, replacing with ...
7621 (selection_quantum): ... new function, which avoids overflow.
7623 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7624 assumption that selection length fits in 'int'.

7632 Redo calculations to avoid overflow.
7633 (x_reply_selection_request): When sending hint, ceiling it at
7634 X_LONG_MAX rather than relying on wraparound overflow to send

7637 (lisp_data_to_selection_data, x_property_data_to_lisp):
7638 Check for size-calculation overflow.

7641 Don't store size until memory allocation succeeds.
7642 (x_get_window_property): Plug memory leak on memory exhaustion.
7643 Don't double-block input; malloc is safe here. Don't assume 2**34
7644 - 4 fits in unsigned long. Add an xassert to check
7645 XGetWindowProperty overflow. Be more careful about overflow
7646 calculations, and distinguish size from memory overflow better.
7647 (receive_incremental_selection): When tracing, don't assume
7648 unsigned int is less than INT_MAX.
7649 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7650 harmful) conversions of unsigned short to int.
7651 (lisp_data_to_selection_data): Don't assume that integers
7652 in the range -65535 through -1 fit in an X unsigned short.
7653 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7654 result parameters unless successful. Rely on cons_to_unsigned
7655 to report problems with elements; the old code wasn't right anyway.
7656 (x_check_property_data): Check for int overflow; we cannot use
7657 a wider type due to X limits.
7658 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7690 * lisp.h (hash_lookup, hash_put):
7691 * minibuf.c (Ftest_completion):
7692 Use ptrdiff_t for hash table indexes, not int (which is too
7693 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7694 32-bit --with-wide-int hosts).
7696 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7697 Add a FIXME comment about memory leaks.

7702 * character.h (CHAR_WIDTH):
7703 * indent.c (MULTIBYTE_BYTES_WIDTH):
7704 Use sanitize_char_width to avoid undefined and/or bad behavior
7705 with outlandish widths.
7706 * character.h (sanitize_tab_width): Rename from sanitize_width,
7707 now that we have two such functions. All uses changed.
7708 (sanitize_char_width): New inline function.
7710 Don't assume that tab-width fits in int.
7711 * character.h (sanitize_width): New inline function.
7712 (SANE_TAB_WIDTH): New macro.

7727 (x_send_scroll_bar_event): Likewise. Check that the size does not
7728 exceed limits imposed by XClientMessageEvent, as well as the usual
7729 ptrdiff_t and size_t limits.
7731 * keyboard.c: Overflow, signedness and related fixes.
7732 (make_lispy_movement): Use same integer type in forward decl
7733 that is used in the definition.
7734 (read_key_sequence, keyremap_step):
7735 Change bufsize argument back to int, undoing my 2011-03-30 change.
7736 We prefer signed types, and int is wide enough here.
7737 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7738 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7739 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7740 length, not size_t. Use ptrdiff_t for index, not int.
7741 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7742 possibility of integer overflow.
7744 Overflow, signedness and related fixes for images.
7746 * dispextern.h (struct it.stack[0].u.image.image_id)
7747 (struct_it.image_id, struct image.id, struct image_cache.size)

7753 * nsmenu.m (update_frame_tool_bar):
7754 * xdisp.c (calc_pixel_width_or_height):
7755 * xfns.c (image_cache_refcount):

7757 on typical 64-bit hosts.
7759 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7760 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7761 Omit unnecessary casts to int.

7763 when the callers expect that.
7764 (image_ascent): Redo ascent calculation to avoid int overflow.
7765 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7766 (lookup_image): Remove unnecessary tests.
7767 (xbm_image_p): Locals are now of int, not EMACS_INT,
7768 since parse_image_check makes sure they fit into int.
7769 (png_load, gif_load, svg_load_image):
7770 Prefer int to unsigned where either will do.
7771 (tiff_handler): New function, combining the cores of the
7772 old tiff_error_handler and tiff_warning_handler.
7773 This function is rewritten to use vsnprintf and thereby avoid
7774 stack buffer overflows. It uses only the features of vsnprintf
7775 that are common to both POSIX and native Microsoft.
7776 (tiff_error_handler, tiff_warning_handler): Use it.
7777 (tiff_load, gif_load, imagemagick_load_image):
7778 Don't assume :index value fits in 'int'.
7779 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7780 (imagemagick_load_image): Check that crop parameters fit into
7781 the integer types that MagickCropImage accepts. Don't assume
7782 Vimagemagick_render_type has a nonnegative value. Don't assume
7783 size_t fits in 'long'.
7784 (gs_load): Use printmax_t to print the widest integers possible.
7785 Check for integer overflow when computing image height and width.
7787 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7789 * xdisp.c (redisplay_window): Don't force window start if point

7797 handle_single_display_spec, not just 1 or zero.
7798 (handle_single_display_spec): If the display spec is of the form
7799 `(space ...)', and specifies display in the text area, return 2
7801 (try_cursor_movement): Check for the need to scroll more
7802 accurately, and prefer exact match for point under bidi.
7803 Don't advance `row' beyond the last row of the window.
7805 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7806 into disp_prop; all users changed.
7808 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7809 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7810 for the text covered by the display property.
7812 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7814 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7820 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7821 buffers, return left-to-right.
7822 (set_cursor_from_row): Consider candidate row a win if its glyph
7823 represents a newline and point is on that newline. Fixes cursor
7824 positioning on the newline at EOL of R2L text within L2R
7825 paragraph, and vice versa.
7826 (try_cursor_movement): Check continued rows, in addition to
7827 continuation rows. Fixes unwarranted scroll when point enters a
7828 continued line of R2L text within an L2R paragraph, or vice versa.
7829 (cursor_row_p): Consider the case of point being equal to
7830 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7831 from the end of a short line to the beginning of a continued line
7832 of R2L text within L2R paragraph.
7833 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7834 composed characters.
7836 * bidi.c (bidi_check_type): Use xassert.
7837 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7840 2011-08-23 Eli Zaretskii <eliz@gnu.org>

7845 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7847 * nsfont.m (ns_otf_to_script): Fix typo.
7849 2011-08-22 Kenichi Handa <handa@m17n.org>
7851 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7852 extra slot even if the purpose is char-code-property-table.
7854 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7856 * xdisp.c (redisplay_window): When computing centering_position,
7857 account for the height of the header line. (Bug#8874)
7859 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7860 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7861 candidate is selected by the mouse, and that candidate has a
7862 composed character under the mouse.
7864 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7865 coordinates reported by pos-visible-in-window-p for a composed
7866 character in column zero.
7868 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
7870 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7872 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7874 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7875 consider it a hit if to_charpos is anywhere in the range of the
7876 composed buffer positions.
7878 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7880 * image.c (gif_load): Don't assume that each subimage has the same
7881 dimensions as the base image. Handle disposal method that is
7882 "undefined" by the gif spec (Bug#9335).
7884 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7886 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7887 (Fcondition_case): Document `debug' symbol in error handler.
7889 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7891 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7892 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7893 from an Org mode buffer to a Speedbar frame.
7895 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7896 a composition, take its buffer position from IT->cmp_it.charpos.
7897 Fixes cursor positioning at the beginning of a line that begins
7898 with a composed character.
7900 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7902 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7903 character bidirectional type, use STRONG_L instead. Fixes crashes
7904 in a buffer produced by `describe-categories'.
7906 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7907 members before the level stack, so they would be saved and
7908 restored when copying iterator state. Fixes incorrect reordering
7909 around TABs covered by display properties.
7911 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7913 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7985 ppos_it. Fixes vertical cursor motion when line beginning is
7986 covered by an image. (Bug#9296)
7988 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7990 * nsterm.h (ns_run_ascript): Declare.

7994 (ns_run_ascript): New function.
7995 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7996 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7997 the event loop. Get status from as_status (Bug#7276).
7999 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8000 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8001 the event loop (Bug#7276).

8027 (Fnetwork_interface_list): Allocate in increments of bytes instead
8028 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8029 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8031 (struct ifflag_def): notrailers is smart on OSX.
8032 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8033 Get hardware address with getifaddrs if available.
8035 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8037 * xdisp.c (iterate_out_of_display_property): xassert that
8038 IT->position is set to within IT->object's boundaries. Break from
8039 the loop as soon as EOB is reached; avoids infloops in redisplay
8040 when IT->position is set up wrongly due to some bug.
8041 Set IT->current to match the bidi iterator unconditionally.
8042 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8043 entry. Force push_it to save on the stack the current
8044 buffer/string position, to be restored by pop_it. Fix flags in
8045 the iterator structure wrt the object coming from a display
8046 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8047 properties. (Bug#9284)
8049 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8051 * fontset.c (fontset_get_font_group): Add proper type checks.

8066 properties and overlays.
8068 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8070 * editfns.c (Fset_time_zone_rule): Document relationship with the

8092 word-wrap under bidirectional display. (Bug#9224)
8094 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8095 is non-zero, even if the data buffer is NULL. Fixes a crash in
8096 vertical-motion with longlines-mode. (Bug#9254)
8098 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8100 * bidi.c <bidi_cache_total_alloc>: Now static.

8106 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8107 amount allocated this far in `bidi_cache_total_alloc'.
8108 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8109 non-zero, only free the data buffer without restoring the cache
8110 contents. All callers changed.

8114 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8115 (move_it_in_display_line, move_it_to)
8116 (move_it_vertically_backward, move_it_by_lines): Replace the call
8117 to xfree to an equivalent call to bidi_unshelve_cache.
8118 (move_it_in_display_line_to): Fix logic of returning
8119 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8121 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8123 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

8197 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8199 (reseat_at_next_visible_line_start): Use the bidi iterator state
8200 returned by forward_to_next_line_start to restore the state of
8201 it->bidi_it after backing up to previous newline. (Bug#9212)

8207 (regexec): Fix type of `ret'. (Bug#9203)
8209 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8211 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8212 This is needed if max-image-size is a floating-point number.
8214 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8216 * print.c (print_object): Print empty symbol as ##.
8218 * lread.c (read1): Read ## as empty symbol.
8220 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8222 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8223 setting frame foreground color (Bug#9175).
8224 (x_set_background_color): Likewise.
8226 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8227 contents (Bug#9176).
8228 (EmacsTooltip -init): Remove bezels and add shadows to
8231 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8232 or scroll bar (Bug#8470).
8234 * nsfont.m (nsfont_open): Remove assignment to voffset and
8235 unnecessary vars hshink, expand, hd, full_height, min_height.
8236 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8238 * nsterm.h (nsfont_info): Remove voffset field.
8240 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8242 Implement strike-through and overline on NextStep (Bug#8863).
8244 * nsfont.m (nsfont_open): Use underline position provided by font,
8245 instead of hard-coded value of 2.
8246 (nsfont_draw): Call ns_draw_text_decoration instead.
8248 * nsterm.h: Add declaration for ns_draw_text_decoration.
8250 * nsterm.m (ns_draw_text_decoration): New function for drawing
8251 underline, overline, and strike-through.
8252 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8253 ns_draw_text_decoration. Change treatment of cursor drawing to
8254 accommodate underlining, etc.
8256 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8258 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8261 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8263 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8264 Without this fix, if a signal arrives just after memory fills up,
8265 'malloc' might be invoked reentrantly.
8267 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8268 In other words, assume that every image size is allowed, on non-X
8269 hosts. This assumption is probably wrong, but it lets Emacs compile.
8271 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8273 * regex.c (re_iswctype): Convert return values to boolean.
8275 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8277 * xdisp.c (compute_display_string_pos): Don't use cached display
8278 string position if the buffer had its restriction changed.
8281 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8283 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8285 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8287 Integer signedness and overflow and related fixes. (Bug#9079)
8289 * bidi.c: Integer size and overflow fixes.
8290 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8291 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8292 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8293 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8294 (bidi_find_other_level_edge):
8295 Use ptrdiff_t instead of EMACS_INT where either will do.
8296 This works better on 32-bit hosts configured --with-wide-int.
8297 (bidi_cache_ensure_space): Check for size-calculation overflow.
8298 Use % rather than repeated addition, for better worst-case speed.
8299 Don't set bidi_cache_size until after xrealloc returns, because it
8301 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8302 (bidi_cache_ensure_space): Also check that the bidi cache size
8303 does not exceed that of the largest Lisp string or buffer. See Eli
8304 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8306 * alloc.c (__malloc_size_t): Remove.
8307 All uses replaced by size_t. See Andreas Schwab's note
8308 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8310 * image.c: Improve checking for integer overflow.
8311 (check_image_size): Assume that f is nonnull, since
8312 it is always nonnull in practice. This is one less thing to
8313 worry about when checking for integer overflow later.
8314 (x_check_image_size): New function, which checks for integer
8315 overflow issues inside X.
8316 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8317 This removes the need for a memory_full check.
8318 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8319 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8320 (xbm_read_bitmap_data): Change locals back to 'int', since
8321 their values must fit in 'int'.
8322 (xpm_load_image, png_load, tiff_load):
8323 Invoke x_create_x_image_and_pixmap earlier,
8324 to avoid much needless work if the image is too large.
8325 (tiff_load): Treat overly large images as if
8326 x_create_x_image_and_pixmap failed, not as malloc failures.
8327 (gs_load): Use x_check_image_size.
8329 * gtkutil.c: Omit integer casts.
8330 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8331 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8333 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8335 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8336 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8337 would wrongly return t on a 64-bit host.
8339 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8340 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8341 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8342 and therefore cause GCC to emit a bogus diagnostic in some cases.
8344 * image.c: Integer signedness and overflow and related fixes.
8345 This is not an exhaustive set of fixes, but it's time to
8346 record what I've got.
8347 (lookup_pixel_color, check_image_size): Remove redundant decls.
8348 (check_image_size): Don't assume that arbitrary EMACS_INT values
8349 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8350 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8351 (tiff_load, imagemagick_load_image):
8352 Check for overflow in size calculations.
8353 (x_create_x_image_and_pixmap): Remove unnecessary test for
8354 xmalloc returning NULL; that can't happen.
8355 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8356 (xpm_color_bucket): Use better integer hashing function.
8357 (xpm_cache_color): Don't possibly over-allocate memory.
8358 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8359 (gif_memory_source):
8360 Use ptrdiff_t, not int or size_t, to record sizes.
8361 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8362 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8363 either works, as we prefer signed integers.
8364 (tiff_read_from_memory, tiff_write_from_memory):
8365 Return tsize_t, not size_t, since that's what the TIFF API wants.
8366 (tiff_read_from_memory): Don't fail simply because the read would
8367 go past EOF; instead, return a short read.
8368 (tiff_load): Omit no-longer-needed casts.
8369 (Fimagemagick_types): Don't assume size fits into 'int'.
8371 Improve hashing quality when configured --with-wide-int.
8372 * fns.c (hash_string): New function, taken from sxhash_string.
8373 Do not discard information about ASCII character case; this
8374 discarding is no longer needed.
8375 (sxhash-string): Use it. Change sig to match it. Caller changed.
8376 * lisp.h: Declare it.
8377 * lread.c (hash_string): Remove, since we now use fns.c's version.
8378 The fns.c version returns a wider integer if --with-wide-int is
8379 specified, so this should help the quality of the hashing a bit.
8381 * emacs.c: Integer overflow minor fix.
8382 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8383 Define only if GNU_LINUX.
8384 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8386 * dispnew.c: Integer signedness and overflow fixes.
8387 Remove unnecessary forward decls, that were a maintenance hassle.
8388 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8390 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8391 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8392 (prepare_desired_row, line_draw_cost):
8393 Use int, not unsigned, where either works.
8394 (save_current_matrix, restore_current_matrix):
8395 Use ptrdiff_t, not size_t, where either works.
8396 (init_display): Check for overflow more accurately, and without
8397 relying on undefined behavior.
8399 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8400 Remove, replacing with the new symbols in lisp.h. All uses changed.
8401 * fileio.c (make_temp_name):
8402 * filelock.c (lock_file_1, lock_file):
8403 * xdisp.c (message_dolog):
8404 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8405 Use pMd etc. instead.
8406 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8407 replacing the pWIDE etc. symbols removed from editfns.c.
8409 * keyboard.h (num_input_events): Now uintmax_t.
8410 This is (very slightly) less likely to mess up due to wraparound.
8413 * buffer.c: Integer signedness fixes.
8414 (alloc_buffer_text, enlarge_buffer_text):
8415 Use ptrdiff_t rather than size_t when either will do, as we prefer
8418 * alloc.c: Integer signedness and overflow fixes.
8419 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8420 (__malloc_size_t): Default to size_t, not to int.
8421 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8422 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8423 Prefer ptrdiff_t to size_t when either would do, as we prefer
8425 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8426 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8427 Now const. Initialize with values that are in range even if char
8429 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8430 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8431 These functions do the right thing with sizes > 2**32.
8432 (check_depth): Now ptrdiff_t, not int.
8433 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8434 Adjust to new way of storing sizes. Check for size overflow bugs
8436 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8437 slightly wrong anyway, as it missed one instance of
8438 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8439 (refill_memory_reserve): Omit needless cast to size_t.
8440 (mark_object_loop_halt): Mark as externally visible.
8442 * xselect.c: Integer signedness and overflow fixes.
8443 (Fx_register_dnd_atom, x_handle_dnd_message):
8444 Use ptrdiff_t, not size_t, since we prefer signed.
8445 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8446 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8447 x_dnd_atoms_size and x_dnd_atoms_length.
8449 * doprnt.c: Prefer signed to unsigned when either works.
8451 * doprnt.c (doprnt):
8453 * xdisp.c (vmessage):
8454 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8455 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8456 prefer signed arithmetic to avoid comparison confusion.
8457 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8458 but is a bit tricky.
8460 Assume freestanding C89 headers, string.h, stdlib.h.
8461 * data.c, doprnt.c, floatfns.c, print.c:
8462 Include float.h unconditionally.
8463 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8464 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8465 * regex.c: Likewise for stddef.h, string.h.
8466 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8467 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8468 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8469 (STDC_HEADERS): Remove obsolete defines.
8470 * sysdep.c: Include limits.h unconditionally.
8472 Assume support for memcmp, memcpy, memmove, memset.
8473 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8474 * regex.c (memcmp, memcpy):
8475 Remove; we assume C89 now.
8477 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8478 (__malloc_safe_bcopy): Remove; no longer needed.
8480 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8481 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8482 well either way, and we prefer signed to unsigned.
8484 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8486 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8487 closes the connection while we're reading (bug#9182).
8489 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8491 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8492 are specified (Bug#9168).
8494 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8496 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8497 Found by GCC static checking and --with-wide-int on a 32-bit host.
8499 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8501 * xdisp.c (compute_display_string_pos): Fix logic of caching
8502 previous display string position. Initialize cached_prev_pos to
8503 -1. Fixes slow-down at the beginning of a buffer.
8505 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8507 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8508 for attrs[LFACE_FONTSET_INDEX].
8510 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8512 * xml.c (parse_region): Remove unused local
8513 that was recently introduced.
8515 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8517 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8518 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8520 * xdisp.c (move_it_in_display_line_to): Record the best matching
8521 position for TO_CHARPOS while scanning the line, and restore it on
8522 exit if none of the characters scanned was an exact match.
8523 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8524 when exact match is impossible due to invisible text, and the
8525 lines are truncated.
8527 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8529 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8532 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8534 Fix a significant slow-down of cursor motion with C-n, C-p,
8535 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8536 auto-repeat under bidi redisplay in fontified buffers.
8537 * xdisp.c (compute_stop_pos_backwards): New function.
8538 (next_element_from_buffer): Call compute_stop_pos_backwards to
8539 find a suitable prev_stop when we find ourselves before
8541 (reseat): Don't look for prev_stop, as that could mean a very long
8543 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8544 <cached_disp_overlay_modiff>: Cache for last found display string
8546 (compute_display_string_pos): Return the cached position if asked
8547 about the same buffer in the same area of character positions, and
8548 the buffer wasn't changed since the time the display string
8549 position was cached.
8551 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8553 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8554 is an integer, which is important for empty lines. (Bug#9149)
8556 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8558 * frame.c (Fmodify_frame_parameters): In tty case, update the
8559 default face if necessary (Bug#4238).
8561 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8563 * editfns.c (Fstring_to_char): No need to explain what a character
8564 is in the docstring (Bug#6576).
8566 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8568 * xml.c (parse_region): Make sure we always return a tree.
8570 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8572 * xml.c (parse_region): If a document contains only comments,
8575 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8577 * xml.c (make_dom): Return comments, too.
8579 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8582 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8583 and the surrounding thread.
8584 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8585 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8586 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8588 * s/openbsd.h (BROKEN_SIGIO): Define.
8589 * unexelf.c (unexec) [__OpenBSD__]:
8590 Don't update the .mdebug section of the Alpha COFF symbol table.
8592 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8594 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8597 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8599 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8600 This fixes some race conditions on the permissions of any newly
8603 * alloc.c (valid_pointer_p): Use pipe, not open.
8604 This fixes some permissions issues when debugging.
8606 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8607 If fchown fails to set both uid and gid, try to set just gid,
8608 as that is sometimes allowed. Adjust the file's mode to eliminate
8609 setuid or setgid bits that are inappropriate if fchown fails.
8611 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8613 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8614 to compare Lisp_Objects.
8615 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8616 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8617 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8619 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8621 * lread.c (read_integer): Unread even EOF character.
8622 (read1): Likewise. Properly record start position of symbol.
8624 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8625 symbol character follows.
8627 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8629 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8630 This works around a problem with the previous change to Fcopy_file.
8631 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8632 and without this change, GCC might complain about discarding
8633 fchown's return value.
8635 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8637 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8639 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8641 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8643 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8645 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8646 it's used from the C level.
8648 * process.c: Use the same condition for POLL_FOR_INPUT in both
8649 keyboard.c and process.c (bug#1858).
8651 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8653 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8654 (Fgnutls_boot): Use it.
8656 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8658 * doc.c (Fsubstitute_command_keys): Revert last change.
8660 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8662 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8663 quotes the next character, and doesn't affect other longer
8664 sequences (bug#8935).
8666 * lread.c (syms_of_lread): Clarify that is isn't only
8667 `eval-buffer' and `eval-defun' that's affected by
8668 `lexical-binding' (bug#8460).
8670 2011-07-15 Eli Zaretskii <eliz@gnu.org>

8731 the iterator is before prev_stop.
8732 (init_iterator): Initialize bidi_p from the default value of

9209 (clone_per_buffer_values): Don't assume that

9250 Random fixes. E.g., (random) never returned negative values.
9251 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9252 subseconds part to the entropy, as that's a bit more random.
9253 Prefer signed to unsigned, since the signedness doesn't matter and
9254 in general we prefer signed. When given a limit, use a
9255 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9256 latter isn't right if USE_2_TAGS_FOR_INTS.
9257 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9258 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9270 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9271 This is more efficient than Ffile_directory_p and avoids a minor race.
9273 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9275 * buffer.c (Foverlay_put): Say what the return value is
9278 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9279 is a directory before asking whether to use the file name
9281 (barf_or_query_if_file_exists): Make the "File is a directory"
9282 error be more correct.
9284 * fns.c (Frequire): Remove the mention of the .gz files, since
9285 that's installation-specific, but keep the mention of
9286 `get-load-suffixes'.
9288 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9290 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9301 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9403 * eval.c (struct backtrace): Simplify and port the data structure.
9404 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9405 signed bit field, as this assumption is not portable and it makes
9406 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9407 "char debug_on_exit : 1" as this is not portable either; instead,
9408 use the portable "unsigned int debug_on_exit : 1". Remove unused
9409 member evalargs. Remove obsolete comments about cc bombing out.
9411 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9588 Use ptrdiff_t, not int, for sizes.
9589 Don't increment bufsize until after realloc succeeds.
9590 Check for size-calculation overflow.
9591 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
9593 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9595 * lread.c: Integer overflow fixes.
9596 (read_integer): Radix is now EMACS_INT, not int,
9597 to improve quality of diagnostics for out-of-range radices.
9598 Calculate buffer size correctly for out-of-range radices.
9599 (read1): Check for integer overflow in radices, and in
9600 read-circle numbers.
9601 (read_escape): Avoid int overflow.
9602 (Fload, openp, read_buffer_size, read1)
9603 (substitute_object_recurse, read_vector, read_list, map_obarray):
9604 Use ptrdiff_t, not int, for sizes.
9605 (read1): Use EMACS_INT, not int, for sizes.
9606 Check for size overflow.
9608 * image.c (cache_image): Check for size arithmetic overflow.
9610 * lread.c: Integer overflow issues.
9611 (saved_doc_string_size, saved_doc_string_length)
9612 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9613 Now ptrdiff_t, not int.
9614 (read1): Don't assume doc string length fits in int. Check for
9615 out-of-range doc string lengths.
9616 (read_list): Don't assume file position fits in int.
9617 (read_escape): Check for hex character overflow.
9619 2011-06-22 Leo Liu <sdl.web@gmail.com>
9621 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9622 Move to minibuffer.el.
9624 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9626 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9627 The following patches are for when GLYPH_DEBUG && !XASSERT.
9628 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9629 * dispnew.c (flush_stdout):
9630 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9631 Mark as externally visible.
9632 * dispnew.c (check_window_matrix_pointers): Now static.
9633 * dispnew.c (window_to_frame_vpos):
9634 * xfns.c (unwind_create_frame):
9635 * xterm.c (x_check_font): Remove unused local.
9636 * scroll.c (CHECK_BOUNDS):
9637 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9638 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9639 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9640 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9641 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9643 (debug_method_add): Use va_list and vsprintf rather than relying
9644 on undefined behavior with wrong number of arguments.
9645 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9646 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9647 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9648 since we're not interested in debugging glyphs with old libraries.
9649 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9650 GCC 4.6.0's static checking.
9652 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9654 Integer overflow and signedness fixes (Bug#8873).
9655 A few related buffer overrun fixes, too.

9659 * dispextern.h (struct face.stipple):
9660 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9661 (x_bitmap_mask, x_allocate_bitmap_record)
9662 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9663 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9664 (x_create_bitmap_from_xpm_data):
9665 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9666 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9668 * xfaces.c (load_pixmap):
9669 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9670 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9671 (.bitmaps_last, struct x_output.icon_bitmap):
9672 Use ptrdiff_t, not int, for bitmap indexes.
9673 (x_allocate_bitmap_record): Check for size overflow.
9674 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9676 Use ptrdiff_t, not int, for overlay counts.
9677 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9678 * editfns.c (overlays_around, get_pos_property):
9679 * textprop.c (get_char_property_and_overlay):
9680 * xdisp.c (next_overlay_change, note_mouse_highlight):
9681 * xfaces.c (face_at_buffer_position):
9682 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9683 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9684 (Fnext_overlay_change, Fprevious_overlay_change)
9685 (mouse_face_overlay_overlaps, Foverlays_in):
9686 Use ptrdiff_t, not int, for sizes.
9687 (overlays_at, overlays_in): Check for size-calculation overflow.
9689 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9691 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9692 (x_session_initialize): Do not assume string length fits in int.
9694 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9695 This is unlikely, but can occur if DPI is outlandish.
9697 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9698 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9700 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9701 * xrdb.c (magic_file_p, search_magic_path):
9702 Omit last arg SUFFIX; it was always 0. All callers changed.
9703 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9705 * xfont.c (xfont_match): Avoid need for strlen.
9707 * xfns.c: Don't assume strlen fits in int.
9708 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9710 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9711 not unsigned long, as we prefer signed integers. All callers changed.
9712 Detect integer overflow in repeat count.
9713 (message_dolog): Don't assume print length fits in 39 bytes.
9714 (display_mode_element): Don't assume strlen fits in int.
9716 * termcap.c: Don't assume sizes fit in int and never overflow.
9717 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9718 (gobble_line): Check for size-calculation overflow.
9720 * minibuf.c (Fread_buffer):
9721 * lread.c (intern, intern_c_string):
9722 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9723 Don't assume string length fits in int.
9725 * keyboard.c (parse_tool_bar_item):
9726 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9728 * font.c: Don't assume string length fits in int.
9729 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9730 Use ptrdiff_t, not int.
9731 (font_intern_prop): Don't assume string length fits in int.
9732 Don't assume integer property fits in fixnum.
9733 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9735 * filelock.c: Fix some buffer overrun and integer overflow issues.
9736 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9737 Reformulate so as not to need the command string.
9738 Invoke gzip -cd rather than gunzip, as it's more portable.
9739 (lock_info_type, lock_file_1, lock_file):
9740 Don't assume pid_t and time_t fit in unsigned long.
9741 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9742 (current_lock_owner): Prefer signed type for sizes.
9743 Use memcpy, not strncpy, where memcpy is what is really wanted.
9744 Don't assume (via atoi) that time_t and pid_t fit in int.
9745 Check for time_t and/or pid_t out of range, e.g., via a network share.
9746 Don't alloca where an auto var works fine.
9748 * fileio.c: Fix some integer overflow issues.
9749 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9750 Don't assume string length fits in int.
9751 (directory_file_name): Don't assume string length fits in long.
9752 (make_temp_name): Don't assume pid fits in int, or that its print
9753 length is less than 20.
9755 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9757 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9759 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9761 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9762 We prefer signed integers, even for size calculations.
9764 * emacs.c: Don't assume string length fits in 'int'.
9765 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9766 (main): Don't invoke strlen when not needed.
9768 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9769 (XD_DEBUG_MESSAGE): Don't waste a byte.
9771 * callproc.c (getenv_internal_1, getenv_internal)
9773 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9775 * lread.c (invalid_syntax): Omit length argument.
9776 All uses changed. This doesn't fix a bug, but it simplifies the
9777 code away from its former Hollerith-constant appearance, and it's
9778 one less 'int' to worry about when looking at integer-overflow issues.
9779 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9781 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9782 This didn't break anything, but it didn't help either.
9783 It's confusing to put a bogus integer in a place where the actual
9784 value does not matter.
9785 (LIST_END_P): Remove unused macro and its bogus comment.
9786 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9788 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9789 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9791 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9792 We prefer signed types, and the value cannot exceed the EMACS_INT
9793 range anyway (because otherwise the length would not be representable).
9794 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9795 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9796 This avoids a GCC warning when WIDE_EMACS_INT.
9798 * indent.c (sane_tab_width): New function.
9799 (current_column, scan_for_column, Findent_to, position_indentation)
9800 (compute_motion): Use it. This is just for clarity.
9801 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9803 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9805 * lisp.h (lint_assume): New macro.
9806 * composite.c (composition_gstring_put_cache):
9807 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9809 * editfns.c, insdel.c:
9810 Omit unnecessary forward decls, to simplify future changes.
9812 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9814 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9816 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9817 Use much-faster test for byte-length change.
9818 Don't assume string byte-length fits in 'int'.
9819 Check that character arg fits in 'int'.
9820 (mapcar1): Declare byte as byte, for clarity.
9822 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9824 * fns.c (concat): Catch string overflow earlier.
9825 Do not rely on integer wraparound.
9827 * dispextern.h (struct it.overlay_strings_charpos)
9828 (struct it.selective): Now EMACS_INT, not int.
9829 * xdisp.c (forward_to_next_line_start)
9830 (back_to_previous_visible_line_start)
9831 (reseat_at_next_visible_line_start, next_element_from_buffer):
9832 Don't arbitrarily truncate the value of 'selective' to int.
9834 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9836 * composite.c: Don't truncate sizes to 'int'.
9837 (composition_gstring_p, composition_reseat_it)
9838 (composition_adjust_point): Use EMACS_INT, not int.
9839 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9840 not EMACS_UINT, for indexes.
9842 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9844 * buffer.c: Include <verify.h>.
9845 (struct sortvec.priority, struct sortstr.priority):
9846 Now EMACS_INT, not int.
9847 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9848 (struct sortstr.size, record_overlay_string)
9849 (struct sortstrlist.size, struct sortlist.used):
9850 Don't truncate size to int.
9851 (record_overlay_string): Check for size-calculation overflow.
9852 (init_buffer_once): Check at compile-time, not run-time.
9854 2011-06-22 Jim Meyering <meyering@redhat.com>
9856 Don't leak an XBM-image-sized buffer
9857 * image.c (xbm_load): Free the image buffer after using it.
9859 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9862 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9863 that Sun C diagnosed.
9864 * fns.c (secure_hash): Fix pointer signedness issue.
9865 * intervals.c (static_offset_intervals): New function.
9866 (offset_intervals): Use it.
9868 2011-06-21 Leo Liu <sdl.web@gmail.com>
9871 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9874 * fns.c (secure_hash): Rename from crypto_hash_function and change
9875 the first arg to accept symbols.
9876 (Fsecure_hash): New primitive.
9877 (syms_of_fns): New symbols.
9879 2011-06-20 Deniz Dogan <deniz@dogan.se>
9881 * process.c (Fset_process_buffer): Clarify return value in
9884 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9886 * dispnew.c (add_window_display_history): Use BVAR.
9888 * xdisp.c (debug_method_add): Use BVAR.
9889 (check_window_end, dump_glyph_matrix, dump_glyph)
9890 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9892 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9895 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9896 check till after the cache is created in init_frame_faces.
9898 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9900 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9902 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9904 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9905 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9906 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9908 Improve buffer-overflow checking (Bug#8873).
9909 * fileio.c (Finsert_file_contents):
9910 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9911 Remove the old (too-loose) buffer overflow checks.
9912 They weren't needed, since make_gap checks for buffer overflow.
9913 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9914 The old code merely checked for Emacs fixnum overflow, and relied
9915 on undefined (wraparound) behavior. The new code avoids undefined
9916 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9918 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9919 Tune. Don't use wider integers than needed. Don't use alloca.
9920 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9922 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9924 * insdel.c, lisp.h (buffer_overflow): New function.
9925 (insert_from_buffer_1, replace_range, replace_range_2):
9926 * insdel.c (make_gap_larger):
9927 * editfns.c (Finsert_char):
9928 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9930 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9932 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9934 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9936 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9937 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9939 * fileio.c: Don't assume EMACS_INT fits in off_t.
9940 (emacs_lseek): New static function.
9941 (Finsert_file_contents, Fwrite_region): Use it.
9942 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9944 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9946 * fns.c: Don't overflow int when computing a list length.
9947 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9948 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9949 truncation on 64-bit hosts. Check for QUIT every
9950 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9951 faster and is responsive enough.
9952 (Flength): Report an error instead of overflowing an integer.
9953 (Fsafe_length): Return a float if the value is not representable
9954 as a fixnum. This shouldn't happen except in contrived situations.
9955 (Fnthcdr, Fsort): Don't assume list length fits in int.
9956 (Fcopy_sequence): Don't assume vector length fits in int.
9958 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9959 (header_size, word_size): New constants.
9960 (allocate_vectorlike): Don't check size overflow here.
9961 (allocate_vector): Check it here instead, since this is the only
9962 caller of allocate_vectorlike that could cause overflow.
9963 Check that the new vector's length is representable as a fixnum.
9965 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9966 The previous code was bogus. For example, next_almost_prime (32)
9967 returned 39, which is undesirable as it is a multiple of 3; and
9968 next_almost_prime (24) returned 25, which is a multiple of 5 so
9969 why was the code bothering to check for multiples of 7?
9971 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9973 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9975 Variadic C functions now count arguments with ptrdiff_t.
9976 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9977 Back then I didn't know that the Emacs coding style prefers signed int.
9978 Also, in the meantime I found a few more instances where arguments
9979 were being counted with int, which may truncate counts on 64-bit
9980 machines, or EMACS_INT, which may be unnecessarily wide.
9981 * lisp.h (struct Lisp_Subr.function.aMANY)
9982 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9983 Arg counts are now ptrdiff_t, not size_t.
9984 All variadic functions and their callers changed accordingly.
9985 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9986 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9987 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9988 * callint.c (Fcall_interactively): Check arg count for overflow,
9989 to avoid potential buffer overrun. Use signed char, not 'int',
9990 for 'varies' array, so that we needn't bother to check its size
9991 calculation for overflow.
9992 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9993 * eval.c (apply_lambda):
9994 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9995 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9996 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9998 * callint.c (Fcall_interactively): Don't use index var as event count.
10000 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10001 * mem-limits.h (SIZE): Remove; no longer used.
10003 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10005 Remove unnecessary casts.
10006 * xterm.c (x_term_init):
10007 * xfns.c (x_set_border_pixel):
10008 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10009 These aren't needed now that we assume ANSI C.
10011 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10012 It's more likely to cause problems (due to unsigned overflow)
10015 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10017 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10019 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10021 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10023 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10025 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10027 GLYPH_CODE_FACE returns EMACS_INT, not int.
10028 * dispextern.h (merge_faces):
10029 * xfaces.c (merge_faces):
10030 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10031 Don't assume EMACS_INT fits in int.
10033 * character.h (CHAR_VALID_P): Remove unused parameter.
10034 * fontset.c, lisp.h, xdisp.c: All uses changed.
10036 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10038 * fns.c (concat): Minor tuning based on overflow analysis.
10039 This doesn't fix any bugs. Use int to hold character, instead
10040 of constantly refetching from Emacs object. Use XFASTINT, not
10041 XINT, for value known to be a character. Don't bother comparing
10042 a single byte to 0400, as it's always less.
10044 * floatfns.c (Fexpt):
10045 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10047 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10050 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10052 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10053 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10054 incorrectly succeed when S was a string, because 4294967386 was
10055 truncated before it was used.
10057 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10058 Otherwise, an out-of-range integer could cause undefined behavior
10061 * composite.c: Use int, not EMACS_INT, for characters.
10062 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10063 EMACS_INT, for values that are known to be in character range.
10064 This doesn't fix any bugs but is the usual style inside Emacs and
10065 may generate better code on 32-bit machines.
10067 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10068 This is for reasons similar to the recent CHAR_STRING fix.
10069 * charset.c (Fencode_char): Check that character arg is actually
10070 a character. Pass an int to ENCODE_CHAR.
10071 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10072 wider than 'int', as a compile-time check to prevent future regressions
10075 * character.c (char_string): Remove unnecessary casts.
10077 Make sure a 64-bit char is never passed to CHAR_STRING.
10078 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10079 by silently ignoring the top 32 bits, allowing some values
10080 that were far too large to be valid characters.
10081 * character.h: Include <verify.h>.
10082 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10083 arguments are no wider than unsigned, as a compile-time check
10084 to prevent future regressions in this area.
10086 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10087 (Fsubst_char_in_region):
10089 * xdisp.c (decode_mode_spec_coding):
10090 Adjust to CHAR_STRING's new requirement.
10091 * editfns.c (Finsert_char, Fsubst_char_in_region):
10092 * fns.c (concat): Check that character args are actually
10093 characters. Without this test, these functions did the wrong
10094 thing with wildly out-of-range values on 64-bit hosts.
10096 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10097 These casts should not be needed on 32-bit hosts, either.
10098 * keyboard.c (read_char):
10099 * lread.c (Fload): Remove casts to unsigned.
10101 * lisp.h (UNSIGNED_CMP): New macro.
10102 This fixes comparison bugs on 64-bit hosts.
10103 (ASCII_CHAR_P): Use it.
10104 * casefiddle.c (casify_object):
10105 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10106 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10107 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10108 * dispextern.h (FACE_FROM_ID):
10109 * keyboard.c (read_char): Use UNSIGNED_CMP.
10111 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10112 not to EMACS_INT, to avoid GCC warning.
10114 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10116 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10117 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10118 isn't needed on 32-bit machines.
10120 * buffer.c (Fgenerate_new_buffer_name):
10121 Use EMACS_INT for count, not int.
10122 (advance_to_char_boundary): Return EMACS_INT, not int.
10124 * data.c (Qcompiled_function): Now static.
10126 * window.c (window_body_lines): Now static.
10128 * image.c (gif_load): Rename local to avoid shadowing.
10130 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10131 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10132 * alloc.c (make_save_value): Integer argument is now of type
10133 ptrdiff_t, not int.
10134 (mark_object): Use ptrdiff_t, not int.
10135 * lisp.h (pD): New macro.
10136 * print.c (print_object): Use it.
10138 * alloc.c: Use EMACS_INT, not int, to count objects.
10139 (total_conses, total_markers, total_symbols, total_vector_size)
10140 (total_free_conses, total_free_markers, total_free_symbols)
10141 (total_free_floats, total_floats, total_free_intervals)
10142 (total_intervals, total_strings, total_free_strings):
10143 Now EMACS_INT, not int. All uses changed.
10144 (Fgarbage_collect): Compute overall total using a double, so that
10145 integer overflow is less likely to be a problem. Check for overflow
10146 when converting back to an integer.
10147 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10148 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10149 These were 'int' variables that could overflow on 64-bit hosts;
10150 they were never used, so remove them instead of repairing them.
10151 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10152 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10153 Previously, this ceilinged at INT_MAX, but that doesn't work on
10155 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10157 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10158 (allocate_vectorlike): Check for ptrdiff_t overflow.
10159 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10160 when a (possibly-narrower) signed value would do just as well.
10161 We prefer using signed arithmetic, to avoid comparison confusion.
10163 * alloc.c: Catch some string size overflows that we were missing.
10164 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10165 for convenience in STRING_BYTES_MAX.
10166 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10167 The definition here is exact; the one in lisp.h was approximate.
10168 (allocate_string_data): Check for string overflow. This catches
10169 some instances we weren't catching before. Also, it catches
10170 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10171 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10172 and ptrdiff_t and EMACS_INT are both 64 bits.
10174 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10175 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10176 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10178 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10180 * alloc.c (Fmake_string): Check for out-of-range init.
10182 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10184 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10186 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10188 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

10192 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10193 (style_changed_cb): Call update_theme_scrollbar_width and call
10194 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10195 all frames (Bug#8505).

10199 and height if HAVE_GTK3 (Bug#8505).
10200 (scroll_bar_width_for_theme): New variable.
10201 (update_theme_scrollbar_width): New function.
10202 (xg_get_default_scrollbar_width): Move code to
10203 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

10206 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10208 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

10215 * window.c (temp_output_buffer_show): Call display_buffer with
10216 second argument Vtemp_buffer_show_specifiers and reset latter
10217 immediately after the call.
10218 (Vtemp_buffer_show_specifiers): New variable.
10219 (auto_window_vscroll_p, next_screen_context_lines)
10220 (Vscroll_preserve_screen_position): Remove leading asterisks from

10753 instead of using explicit *_CHAR codes.
10754 (bidi_resolve_explicit, bidi_resolve_weak):

10771 (display_prop_intangible_p): Reimplement to call
10772 handle_display_spec instead of single_display_spec_intangible_p.

10784 value of a `display' property is a "replacing spec".
10785 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10786 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10814 All callers changed. (Bug#8762)
10816 * gnutls.c: Use Emacs's memory allocators.
10817 Without this change, the gnutls library would invoke malloc etc.
10818 directly, which causes problems on non-SYNC_INPUT hosts, and which
10819 runs afoul of improving memory_full behavior. (Bug#8761)
10820 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10821 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10822 xfree instead of the default malloc, realloc, free.
10823 (Fgnutls_boot): No need to check for memory allocation failure,
10824 since xmalloc does that for us.

10848 * alloc.c (allocate_vectorlike):
10849 Check for overflow in vector size calculations.
10850 * ccl.c (ccl_driver):
10851 Check for overflow when converting EMACS_INT to int.

10853 need to be updated by these changes.
10854 * fns.c (make_hash_table, maybe_resize_hash_table):
10855 Check for integer overflow with large hash tables.
10856 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10857 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10858 (SXHASH_REDUCE): New macro.
10859 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10860 Use it instead of discarding useful hash info with large hash values.
10861 (sxhash_float): New function.
10862 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10863 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10864 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10865 Rewrite to use FIXNUM_BITS, as this simplifies things.
10866 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10867 Adjust signatures to match updated version of code.
10868 (consing_since_gc): Now EMACS_INT, since a single hash table can
10869 use more than INT_MAX bytes.

10910 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10911 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10912 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10913 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10914 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10916 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10918 Make it possible to run ./temacs.
10920 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10921 syms_of_callproc does the same thing. Remove test for
10922 "initialized", do it in the caller.
10923 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10925 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10927 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10928 (read_minibuf): Use get_minibuffer.
10929 (syms_of_minibuf): Use DEFSYM.
10930 (Qmetadata): New var.
10931 * data.c (Qbuffer): Don't make it static.
10932 (syms_of_data): Use DEFSYM.
10934 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10936 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10937 (CCL_CODE_MIN): New macro.
10939 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10941 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10943 * eval.c (Qdebug): Now static.
10944 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10945 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10946 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10948 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10950 * image.c: Various fixes to ImageMagick code comments.
10951 (Fimagemagick_types): Doc fix.
10953 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10955 Minor fixes prompted by GCC 4.6.0 warnings.
10957 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10959 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10960 (x_clipboard_manager_save_all): Move extern decl to ...
10961 * xterm.h: ... here, so that it can be checked for consistency.
10963 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10965 * xselect.c (x_clipboard_manager_save_frame)
10966 (x_clipboard_manager_save_all): New functions.
10967 (Fx_clipboard_manager_save): Lisp function deleted.
10969 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10970 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10972 * xterm.h: Update prototype.
10974 2011-05-28 William Xu <william.xwl@gmail.com>
10976 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10977 exiting (Bug#8239).
10979 2011-05-28 Jim Meyering <meyering@redhat.com>
10981 Avoid a sign-extension bug in crypto_hash_function.
10982 * fns.c (to_uchar): Define.
10983 (crypto_hash_function): Use it to convert some newly-signed
10984 variables to unsigned, to avoid sign-extension bugs. For example,
10985 without this change, (md5 "truc") would evaluate to
10986 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10987 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10988 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10990 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10992 Integer overflow fixes.
10994 * dbusbind.c: Serial number integer overflow fixes.
10995 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10996 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10997 to hold a serial number that is too large for a fixnum.
10998 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10999 Check for serial numbers out of range. Decode any serial number
11000 that was so large that it became a float. (Bug#8722)
11002 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11003 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11004 Use XFASTINT rather than XUINT when numbers are nonnegative.
11005 (xd_append_arg, Fdbus_method_return_internal):
11006 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11007 arguments, check that Lisp number is nonnegative, rather than
11008 silently wrapping negative numbers around. (Bug#8722)
11009 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11012 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11014 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11016 ccl: Add integer overflow checks.
11017 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11018 (IN_INT_RANGE): New macros.
11019 (ccl_driver): Use them to check for integer overflow when
11020 decoding a CCL program. Many of the new checks are whether XINT (x)
11021 fits in int; it doesn't always, on 64-bit hosts. The new version
11022 doesn't catch all possible integer overflows, but it's an
11023 improvement. (Bug#8719)
11025 * alloc.c (make_event_array): Use XINT, not XUINT.
11026 There's no need for unsigned here.
11028 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11029 This follows up to the 2011-05-06 change that substituted uintptr_t
11030 for EMACS_INT. This case wasn't caught back then.
11032 Rework Fformat to avoid integer overflow issues.
11033 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11034 now (part of C89). Include <verify.h>.
11035 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11036 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11037 (Fformat): Avoid the prepass trying to compute sizes; it was only
11038 approximate and thus did not catch overflow reliably. Instead, walk
11039 through the format just once, formatting and computing sizes as we go,
11040 checking for integer overflow at every step, and allocating a larger
11041 buffer as needed. Keep track separately whether the format is
11042 multibyte. Keep only the most-recently calculated precision, rather
11043 than them all. Record whether each argument has been converted to
11044 string. Use EMACS_INT, not int, for byte and char and arg counts.
11045 Support field widths and precisions larger than INT_MAX. Avoid
11046 sprintf's undefined behavior with conversion specifications such as %#d
11047 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11048 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11049 formatting out-of-range floating point numbers with int
11050 formats. (Bug#8668)
11052 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11054 * data.c: Avoid integer truncation in expressions involving floats.
11055 * data.c: Include <intprops.h>.
11056 (arith_driver): When there's an integer overflow in an expression
11057 involving floating point, convert the integers to floating point
11058 so that the resulting value does not suffer from catastrophic
11059 integer truncation. For example, on a 64-bit host (* 4
11060 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11061 Do not rely on undefined behavior after integer overflow.
11063 merge count_size_as_multibyte, parse_str_to_multibyte
11064 * character.c, character.h (count_size_as_multibyte):
11065 Rename from parse_str_to_multibyte; all uses changed.
11066 Check for integer overflow.
11067 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11068 since it's now a duplicate of the other. This is more of
11069 a character than a buffer op, so better that it's in character.c.
11070 * fns.c, print.c: Adjust to above changes.
11072 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11074 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11076 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11078 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11079 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11080 (x_clipboard_manager_save): Now static.
11081 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11083 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11084 (crypto_hash_function): Now static.
11085 Fix pointer signedness problems. Avoid unnecessary initializations.
11087 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11089 * termhooks.h (Vselection_alist): Make it terminal-local.
11091 * terminal.c (create_terminal): Initialize it.
11093 * xselect.c: Support for clipboard managers.
11094 (Vselection_alist): Move to termhooks.h as terminal-local var.
11095 (LOCAL_SELECTION): New macro.
11096 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11097 (symbol_to_x_atom): Remove gratuitous arg.
11098 (x_handle_selection_request, lisp_data_to_selection_data)
11099 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11100 (x_own_selection, x_get_local_selection, x_convert_selection):
11101 New arg, specifying work frame. Use terminal-local Vselection_alist.
11102 (some_frame_on_display): Delete unused function.
11103 (Fx_own_selection_internal, Fx_get_selection_internal)
11104 (Fx_disown_selection_internal, Fx_selection_owner_p)
11105 (Fx_selection_exists_p): New optional frame arg.
11106 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11107 (x_handle_selection_clear): Don't treat other terminals with the
11108 same keyboard specially. Use the terminal-local Vselection_alist.
11109 (x_clear_frame_selections): Use Frun_hook_with_args.
11111 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11113 * xterm.h: Add support for those atoms.
11115 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11117 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11118 (converted_selections, conversion_fail_tag): New global variables.
11119 (x_selection_request_lisp_error): Free the above.
11120 (x_get_local_selection): Remove unnecessary code.
11121 (x_reply_selection_request): Args changed; handle arbitrary array
11122 of converted selections stored in converted_selections.
11123 Separate the XChangeProperty and SelectionNotify steps.
11124 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11125 (x_convert_selection): New function.
11126 (x_handle_selection_event): Simplify.
11127 (x_get_foreign_selection): Don't ignore incoming requests while
11128 waiting for an answer; this will fail when we implement
11129 SAVE_TARGETS, and seems unnecessary anyway.
11130 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11131 (Vx_sent_selection_functions): Doc fix.
11133 2011-05-26 Leo Liu <sdl.web@gmail.com>
11135 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11137 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11139 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11141 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11142 for fringe update if it has periodic bitmap.
11143 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11144 and fringe_bitmap_periodic_p.
11146 * fringe.c (get_fringe_bitmap_data): New function.
11147 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11148 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11149 row. Mark glyph row for fringe update if periodicity changed.
11151 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11152 for fringe update unless it has periodic bitmap.
11154 2011-05-25 Kenichi Handa <handa@m17n.org>
11156 * xdisp.c (get_next_display_element): Set correct it->face_id for
11157 a static composition.
11159 2011-05-24 Leo Liu <sdl.web@gmail.com>
11162 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11164 * fns.c (crypto_hash_function, Fsha1): New function.
11165 (Fmd5): Use crypto_hash_function.
11166 (syms_of_fns): Add Ssha1.
11168 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11170 * gnutls.c: Remove unused macros.
11171 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11172 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11173 Remove macros that are defined and never used.
11174 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11176 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11178 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11179 (Fx_get_selection_internal): Minor cleanup.
11180 (Fx_own_selection_internal): Rename arguments for consistency with
11183 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11185 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11187 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11189 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11191 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11193 * dispnew.c (scrolling_window): Don't exclude the case that the
11194 last enabled row in the desired matrix touches the bottom boundary.
11196 2011-05-21 Glenn Morris <rgm@gnu.org>
11198 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11199 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11200 and add some more files.
11202 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11204 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11205 report_file_error introduced by the change from 2011-05-07.
11207 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11209 * systime.h (Time): Define only if emacs is defined.
11210 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11211 where the include path doesn't have X11/X.h by default. See
11212 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11214 2011-05-20 Kenichi Handa <handa@m17n.org>
11216 * composite.c (find_automatic_composition): Fix previous change.
11218 2011-05-20 Glenn Morris <rgm@gnu.org>
11220 * lisp.mk: New file, split from Makefile.in.
11221 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11222 (shortlisp): Remove.
11223 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11225 2011-05-19 Glenn Morris <rgm@gnu.org>
11227 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11228 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11229 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11230 (lisp): Set the order to that of loadup.el.
11231 (shortlisp): Make it a copy of $lisp.
11232 (SOME_MACHINE_LISP): Remove.
11233 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11234 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11236 2011-05-18 Kenichi Handa <handa@m17n.org>
11238 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11239 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11240 (find_automatic_composition): Mostly rewrite for efficiency.
11242 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11244 * makefile.w32-in: Update dependencies.
11246 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11248 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11249 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11251 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11253 Fix some integer overflow issues, such as string length overflow.
11255 * insdel.c (count_size_as_multibyte): Check for string overflow.
11257 * character.c (lisp_string_width): Check for string overflow.
11258 Use EMACS_INT, not int, for string indexes and lengths; in
11259 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11260 the resulting string length overflows an EMACS_INT; instead,
11261 report a string overflow if no precision given. When checking for
11262 precision exhaustion, use a check that cannot possibly have
11263 integer overflow. (Bug#8675)
11264 * character.h (lisp_string_width): Adjust to new signature.
11266 * alloc.c (string_overflow): New function.
11267 (Fmake_string): Use it. This doesn't change behavior, but saves
11268 a few bytes and will simplify future changes.
11269 * character.c (string_escape_byte8): Likewise.
11270 * lisp.h (string_overflow): New decl.
11272 Fixups, following up to the user-interface timestamp change.
11273 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11274 for UI timestamps, instead of unsigned long.
11275 * msdos.c (mouse_get_pos): Likewise.
11276 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11277 * w32gui.h (Time): Define by including "systime.h" rather than by
11278 declaring it ourselves. (Bug#8664)
11280 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11281 * image.c (clear_image_cache): Likewise.
11283 * term.c (term_mouse_position): Don't assume time_t wraparound.
11285 Be more systematic about user-interface timestamps.
11286 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11287 and sometimes 'EMACS_UINT', to represent these timestamps.
11288 This change causes it to use 'Time' uniformly, as that's what X uses.
11289 This makes the code easier to follow, and makes it easier to catch
11290 integer overflow bugs such as Bug#8664.
11291 * frame.c (Fmouse_position, Fmouse_pixel_position):
11292 Use Time, not unsigned long, for user-interface timestamps.
11293 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11294 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11295 * keyboard.h (last_event_timestamp): Likewise.
11296 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11297 * menu.h (xmenu_show): Likewise.
11298 * term.c (term_mouse_position): Likewise.
11299 * termhooks.h (struct input_event.timestamp): Likewise.
11300 (struct terminal.mouse_position_hook): Likewise.
11301 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11302 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11303 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11304 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11305 what it was before.
11306 * menu.h, termhooks.h: Include "systime.h", for Time.
11308 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11309 Don't assume that the difference between two unsigned long values
11310 can fit into an integer. At this point, we know button_down_time
11311 <= event->timestamp, so the difference must be nonnegative, so
11312 there's no need to cast the result if double-click-time is
11313 nonnegative, as it should be; check that it's nonnegative, just in
11314 case. This bug is triggered when events are more than 2**31 ms
11315 apart (about 25 days). (Bug#8664)
11317 * xselect.c (last_event_timestamp): Remove duplicate decl.
11318 (x_own_selection): Remove needless cast to unsigned long.
11320 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11321 that always fit in int. Use a sentinel instead of a counter, to
11322 avoid a temp and to allay GCC's concerns about possible int overflow.
11323 * frame.h (struct frame): Use int for menu_bar_items_used
11324 instead of EMACS_INT, since it always fits in int.
11326 * menu.c (grow_menu_items): Check for int overflow.
11328 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11330 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11331 Before, the code was not consistent. These values cannot exceed
11332 2**31 - 1 so there's no need to make them unsigned.
11333 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11334 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11335 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11337 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11339 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11340 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11341 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11342 presumably because the widths might not match.
11344 * window.c (size_window): Avoid needless test at loop start.
11346 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11348 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11350 2011-05-12 Drew Adams <drew.adams@oracle.com>
11352 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11354 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11356 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11357 `width' to `bar_area_x' and `bar_area_width', respectively.
11358 (x_scroll_run): Take account of fringe background extension.
11360 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11361 Rename local vars `left' and `width' to `bar_area_x' and
11362 `bar_area_width', respectively.
11363 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11364 background extension.
11366 2011-05-10 Jim Meyering <meyering@redhat.com>
11368 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11370 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11372 * image.c (Finit_image_library): Return t for built-in image types,
11373 like pbm and xbm. (Bug#8640)
11375 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11377 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11379 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11381 * w32console.c (Fset_screen_color): Doc fix.
11382 (Fget_screen_color): New function.
11383 (syms_of_ntterm): Defsubr it.
11385 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11386 unlink the temporary file if Fcall_process didn't create it in the
11388 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11389 child process will be redirected to a file specified with `:file'.
11390 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11391 cue to call_process_cleanup not to close that handle.
11393 2011-05-07 Ben Key <bkey76@gmail.com>
11395 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11396 one of two shell specific rules, either bootstrap-temacs-CMD or
11397 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11398 to the previous implementation of the bootstrap-temacs rule.
11399 The bootstrap-temacs-CMD rule is similar to the previous
11400 implementation of the bootstrap-temacs rule except that it
11401 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11404 These changes, along with some changes to nt/configure.bat,
11405 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11406 earlier fix to add support for --cflags and --ldflags options
11407 that include quotes so that it works whether make uses cmd or
11410 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11412 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11413 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11415 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11416 a string. Handle both cases.
11417 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11418 (Fdbus_register_method): Use Qinvalid_function.
11420 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11422 * makefile.w32-in: Update dependencies.
11423 (LISP_H): Add inttypes.h and stdin.h.
11424 (PROCESS_H): Add unistd.h.
11426 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11428 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11429 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11431 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11433 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11435 * term.c (vfatal): Remove stray call to va_end.
11436 It's not needed and the C Standard doesn't allow it here anyway.
11438 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11439 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11441 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11444 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11446 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11448 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11450 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11452 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11454 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11455 * charset.c (Fdefine_charset_internal): Don't initialize
11456 charset.code_space[15]. The value was garbage, on hosts with
11457 32-bit int (Bug#8600).
11459 * lread.c (read_integer): Be more consistent with string-to-number.
11460 Use string_to_number to do the actual conversion; this avoids
11461 rounding errors and fixes some other screwups. Without this fix,
11462 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11463 (digit_to_number): Move earlier, for benefit of read_integer.
11464 Return -1 if the digit is out of range for the base, -2 if it is
11465 not a digit in any supported base. (Bug#8602)
11467 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11469 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11470 to match comment at start of function. This also removes a
11471 GCC warning about overflow in a 32+64-bit port.
11473 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11475 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11476 Reported by Stefan Monnier in
11477 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11478 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11479 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11481 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11482 (EMACS_UINTPTR): Likewise, with uintptr_t.
11484 * lisp.h: Prefer 64-bit EMACS_INT if available.
11485 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11486 on 32-bit hosts that have 64-bit int, so that they can access
11488 However, temporarily disable this change unless the temporary
11489 symbol WIDE_EMACS_INT is defined.
11491 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11493 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11494 This removes an assumption that EMACS_INT and long are the same
11495 width as pointers. The assumption is true for Emacs porting targets
11496 now, but we want to make other targets possible.
11497 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11498 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11499 In the rest of the code, change types of integers that hold casted
11500 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11501 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11502 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11503 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11504 No need to cast type when ORing.
11505 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11506 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11507 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11508 assume EMACS_INT is the same width as char *.
11509 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11510 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11511 Remove no-longer-needed casts.
11512 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11513 (xg_tool_bar_help_callback, xg_make_tool_item):
11514 Use EMACS_INTPTR to hold an integer
11515 that will be cast to void *; this can avoid a GCC warning
11516 if EMACS_INT is not the same width as void *.
11517 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11518 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11519 (current_message_1, set_message_1):
11520 Use a local to convert to proper width without a cast.
11521 * xmenu.c (dialog_selection_callback): Likewise.
11523 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11524 Also, don't assume VALBITS / RAND_BITS is less than 5,
11525 and don't rely on undefined behavior when shifting a 1 left into
11527 * lisp.h (get_random): Change signature to match.
11529 * lread.c (hash_string): Use size_t, not int, for hash computation.
11530 Normally we prefer signed values; but hashing is special, because
11531 it's better to use unsigned division on hash table sizes so that
11532 the remainder is nonnegative. Also, size_t is the natural width
11533 for hashing into memory. The previous code used 'int', which doesn't
11534 retain enough info to hash well into very large tables.
11535 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11537 * dbusbind.c: Don't possibly lose pointer info when converting.
11538 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11539 Use XPNTR rather than XHASH, so that the high-order bits of
11540 the pointer aren't lost when converting through void *.
11542 * eval.c (Fautoload): Don't double-shift a pointer.
11544 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11546 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11548 * gnutls.c (DEF_GNUTLS_FN):
11549 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11551 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11553 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11556 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11558 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11559 New version that can reserve upto 2GB of heap space.
11561 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11563 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

11573 Update dependencies.
11575 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11577 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11578 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11579 Remove unused parameter `fildes'.
11580 * process.c (read_process_output, send_process): Don't pass it.
11582 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11584 Fix previous change: the library cache is defined in w32.c.
11585 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11586 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11588 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11590 Implement dynamic loading of GnuTLS on Windows.
11592 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11593 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11594 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11597 * gnutls.c (Qgnutls_dll): Define.
11598 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11599 (gnutls_*): Declare function pointers.

11603 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11604 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11605 (emacs_gnutls_write, emacs_gnutls_read)
11606 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11607 (Fgnutls_available_p): New function.
11608 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

11620 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11621 (w32_delayed_load): Move from image.c. When loading a library, record
11622 its filename in the :loaded-from property of the library id.
11623 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11624 Initialize and staticpro them.
11625 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

11628 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11629 instead of gnutls_record_check_pending.
11631 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11633 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11635 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11636 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11639 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11641 * xterm.c (x_set_frame_alpha): Do not set property on anything

11664 * sysdep.c (wait_for_termination_1): Make static.
11665 (wait_for_termination, interruptible_wait_for_termination):
11666 Move after wait_for_termination_1.
11668 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11670 * sysdep.c (interruptible_wait_for_termination): New function
11671 which is like wait_for_termination, but allows keyboard
11674 * callproc.c (Fcall_process): Add (:file "file") as an option for
11676 (Fcall_process_region): Ditto.
11678 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11680 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11681 rather than `XVECTOR (FOO)->size'.
11683 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11684 inttypes.h, as a gnulib replacement is used if it not available in
11687 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11689 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11690 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11691 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11693 * coding.c (coding_alloc_by_realloc): Error out if destination
11694 will grow beyond MOST_POSITIVE_FIXNUM.
11695 (decode_coding_emacs_mule): Abort if there isn't enough place in

11708 * window.c (window_scroll_line_based): Use a marker instead of
11709 simple variables to record original value of point. (Bug#7952)
11711 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11712 produced by %s or %c overflows available buffer space. (Bug#8545)
11714 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11716 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11751 Improve `doprnt' and its usage. (Bug#8545)
11752 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11753 `format_end'. Remove support for %l as a conversion specifier.
11754 Don't use xrealloc. Improve diagnostics when the %l size modifier
11755 is used. Update the commentary.
11757 * eval.c (verror): Simplify calculation of size_t.
11759 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11762 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11764 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11767 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11769 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11770 This makes this file independent of the recent pseudovector change.
11772 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11774 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11776 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11777 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11778 Remove unused local.
11779 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11781 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11782 GCC 4.6.0 optimizes based on type-based alias analysis.
11783 For example, if b is of type struct buffer * and v of type struct
11784 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11785 != &v->size, and therefore "v->size = 1; b->size = 2; return
11786 v->size;" must therefore return 1. This assumption is incorrect
11787 for Emacs, since it type-puns struct Lisp_Vector * with many other
11788 types. To fix this problem, this patch adds a new type struct
11789 vectorlike_header that documents the constraints on layout of vectors
11790 and pseudovectors, and helps optimizing compilers not get fooled
11791 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11792 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11793 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11795 (XSETPVECTYPE): Rewrite in terms of new macro.
11796 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11797 This is a bit clearer, and further avoids the possibility of
11798 undesirable aliasing.
11799 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11800 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11801 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11802 since Lisp_Subr is a special case (no "next" field).
11803 (ASIZE): Now uses header.size rather than size.
11804 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11805 to avoid the hassle of writing XVECTOR (foo)->header.size.
11806 (struct vectorlike_header): New type.
11807 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11808 object, to help avoid aliasing.
11809 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11810 (SUBRP): Likewise, since Lisp_Subr is a special case.
11811 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11812 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11813 (struct Lisp_Hash_Table): Combine first two members into a single
11814 struct vectorlike_header member. All uses of "size" and "next" members
11815 changed to be "header.size" and "header.next".
11816 * buffer.h (struct buffer): Likewise.
11817 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11818 * frame.h (struct frame): Likewise.
11819 * process.h (struct Lisp_Process): Likewise.
11820 * termhooks.h (struct terminal): Likewise.
11821 * window.c (struct save_window_data, struct saved_window): Likewise.
11822 * window.h (struct window): Likewise.
11823 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11824 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11825 * buffer.c (init_buffer_once): Likewise.
11826 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11828 * process.c (Fformat_network_address): Use local var for size,
11831 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11833 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11834 * data.c (atof): Remove decl; no longer used or needed.
11835 (digit_to_number): Move to lread.c.
11836 (Fstring_to_number): Use new string_to_number function, to be
11837 consistent with how the Lisp reader treats infinities and NaNs.
11838 Do not assume that floating-point numbers represent EMACS_INT
11839 without losing information; this is not true on most 64-bit hosts.
11840 Avoid double-rounding errors, by insisting on integers when
11841 parsing non-base-10 numbers, as the documentation specifies.
11842 * lisp.h (string_to_number): New decl, replacing ...
11843 (isfloat_string): Remove.
11844 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11845 (read1): Do not accept +. and -. as integers; this
11846 appears to have been a coding error. Similarly, do not accept
11847 strings like +-1e0 as floating point numbers. Do not report
11848 overflow for integer overflows unless the base is not 10 which
11849 means we have no simple and reliable way to continue.
11850 Break out the floating-point parsing into a new
11851 function string_to_number, so that Fstring_to_number parses
11852 floating point numbers consistently with the Lisp reader.
11853 (digit_to_number): Move here from data.c. Make it static inline.
11854 (E_CHAR, EXP_INT): Remove, replacing with ...
11855 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11856 (string_to_number): New function, replacing isfloat_string.
11857 This function checks for valid syntax and produces the resulting
11858 Lisp float number too. Rework it so that string-to-number
11859 no longer mishandles examples like "1.0e+". Use strtoumax,
11860 so that overflow for non-base-10 numbers is reported only when
11861 there's no portable and simple way to convert to floating point.
11863 * textprop.c (set_text_properties_1): Rewrite for clarity,
11864 and to avoid GCC warning about integer overflow.
11866 * intervals.h (struct interval): Use EMACS_INT for members
11867 where EMACS_UINT might cause problems. See
11868 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11869 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11870 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11872 (offset_intervals): Tell GCC not to worry about length overflow
11873 when negating a negative length.
11875 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11876 (overrun_check_free): Likewise.
11878 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11879 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11882 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11883 (gnutls_make_error): Rename local to avoid shadowing.
11884 (gnutls_emacs_global_deinit): ifdef out; not used.
11885 (Fgnutls_boot): Use const for pointer to readonly storage.
11886 Comment out unused local. Fix pointer signedness problems.
11888 * lread.c (openp): Don't stuff size_t into an 'int'.
11889 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11890 about possible signed overflow.
11892 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11893 (GDK_KEY_g): Don't define if already defined.
11894 (xg_prepare_tooltip): Avoid pointer signedness problem.
11895 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11897 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11898 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11900 * xfns.c (Fx_window_property): Simplify a bit,
11901 to make a bit faster and to avoid GCC 4.6.0 warning.
11902 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11904 * fns.c (internal_equal): Don't assume size_t fits in int.
11906 * alloc.c (compact_small_strings): Tighten assertion a little.
11908 Replace pEd with more-general pI, and fix some printf arg casts.
11909 * lisp.h (pI): New macro, generalizing old pEd macro to other
11910 conversion specifiers. For example, use "...%"pI"d..." rather
11911 than "...%"pEd"...".
11912 (pEd): Remove. All uses replaced with similar uses of pI.
11913 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11914 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11915 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11916 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11917 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11918 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11919 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11921 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11922 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11923 * print.c (safe_debug_print, print_object): Likewise.
11924 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11926 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11927 avoiding the 0 flag, which is not portable.
11928 * process.c (Fmake_network_process): Use pI to avoid cast.
11929 * region-cache.c (pp_cache): Likewise.
11930 * xdisp.c (decode_mode_spec): Likewise.
11931 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11932 behavior on 64-bit hosts with printf arg.
11933 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11934 (x_stop_queuing_selection_requests): Likewise.
11935 (x_get_window_property): Don't truncate byte count to an 'int'
11938 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11939 here, since it parses constructs like leading '-' and spaces,
11940 which are not wanted; and it overflows with large numbers.
11941 Instead, simply match F[0-9]+, which is what is wanted anyway.
11943 * alloc.c: Remove unportable assumptions about struct layout.
11944 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11945 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11946 (allocate_vectorlike, make_pure_vector): Use the new macros,
11947 plus offsetof, to remove unportable assumptions about struct layout.
11948 These assumptions hold on all porting targets that I know of, but
11949 they are not guaranteed, they're easy to remove, and removing them
11950 makes further changes easier.
11952 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11953 This doesn't fix a bug but makes the code clearer.
11954 (string_overrun_cookie): Now const. Use initializers that
11955 don't formally overflow signed char, to avoid warnings.
11956 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11957 can cause Emacs to crash when string overrun checking is enabled.
11958 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11959 multiple of sizeof (EMACS_INT); it need not be, if
11960 alignof(EMACS_INT) < sizeof (EMACS_INT).
11961 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11963 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11970 supposed to be handshaking. (Bug#8556)
11971 Reported by Paul Eggert <eggert@cs.ucla.edu>.

11984 (check_string_free_list): Convert to standard C.
11986 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11988 * w32.c (emacs_gnutls_push): Fix typo.
11990 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11992 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11993 "cast to pointer from integer of different size".
11995 Improve doprnt and its use in verror. (Bug#8545)
11996 * doprnt.c (doprnt): Document the set of format control sequences
11997 supported by the function. Use SAFE_ALLOCA instead of always
12000 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12001 is one byte too soon. Don't use xrealloc; instead xfree and
12004 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12006 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12009 * gnutls.c: Renamed global_initialized to
12010 gnutls_global_initialized. Added internals for the
12011 :verify-hostname-error, :verify-error, and :verify-flags
12012 parameters of `gnutls-boot' and documented those parameters in the
12013 docstring. Start callback support.
12014 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12015 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12016 on error. Return error code.

12018 (emacs_gnutls_read): Likewise.
12019 (Fgnutls_boot): Return handshake error code.

12083 <char-direction-table>: Deleted.
12085 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12087 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12088 * doprnt.c: Include limits.h.
12089 (SIZE_MAX): New macro.
12090 (doprnt): Return a size_t value. 2nd arg is now size_t.
12091 Many local variables are now size_t instead of int or unsigned.
12092 Improve overflow protection. Support `l' modifier for integer
12093 conversions. Support %l conversion. Don't assume an EMACS_INT
12094 argument for integer conversions and for %c.
12096 * lisp.h (doprnt): Restore prototype.
12098 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12099 $(SRC)/character.h.
12101 * Makefile.in (base_obj): Add back doprnt.o.
12103 * deps.mk (doprnt.o): Add back prerequisites.
12104 (callint.o): Depend on character.h.
12106 * eval.c (internal_lisp_condition_case): Include the handler
12107 representation in the error message.
12108 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12109 when breaking from the loop.
12111 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12113 * callint.c (Fcall_interactively): When displaying error message
12114 about invalid control letter, pass the character's codepoint, not
12115 a pointer to its multibyte form. Improve display of the character
12116 in octal and display also its hex code.
12118 * character.c (char_string): Use %x to display the (unsigned)
12119 codepoint of an invalid character, to avoid displaying a bogus
12122 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12123 `error', not SYMBOL_NAME itself.
12125 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12126 character arguments to `error'.
12128 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12129 to `error' in error message about FINAL_CHAR argument. Make sure
12130 FINAL_CHAR is a character, and use %c when it is passed as
12131 argument to `error'.

12195 Define only if needed.
12197 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12198 by pacifying GCC about it. Maybe it's time to retire it?
12199 * xfaces.c (USG, __TIMEVAL__): Likewise.
12201 * dispextern.h (struct redisplay_interface): Rename param
12202 to avoid shadowing.
12203 * termhooks.h (struct terminal): Likewise.
12204 * xterm.c (xembed_send_message): Likewise.
12206 * insdel.c (make_gap_smaller): Define only if
12207 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
12209 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
12212 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
12213 so that we aren't warned about unused symbols.
12215 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
12217 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
12219 * xfns.c (x_real_positions): Mark locals as initialized.
12221 * xmenu.c (xmenu_show): Don't use uninitialized vars.
12223 * xterm.c: Fix problems found by static analysis with other toolkits.
12224 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.

12320 * nsfont.m: Fixed bugs in ns_get_family and
12321 ns_descriptor_to_entity that were caused by using free to
12322 deallocate memory blocks that were allocated by xmalloc (via

12324 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12325 --enable-checking=xmallocoverrun). xfree is now used to
12326 deallocate these memory blocks.

12662 * charset.h (charset_iso_8859_1): Remove decl.
12663 * charset.c (charset_iso_8859_1, charset_emacs, map_charset_for_dump):
12666 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
12667 * ccl.c (Vccl_program_table): Now static.
12668 (check_ccl_update): Remove; unused.
12670 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
12671 * category.h: ... from here.
12672 * category.c (check_category_table, set_category_set): Now static.
12674 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
12675 * lisp.h: Remove these decls.
12677 * buffer.c (buffer_count): Remove unused var.
12679 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
12680 so that it's not optimized away.
12681 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12682 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12683 exported only to the debugger.
12685 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12686 * atimer.h (run_all_atimers): Remove; not exported.
12688 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12689 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12690 was inaccessible from Lisp.
12691 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12692 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12694 alloc.c: Import and export fewer symbols, and remove unused items.
12695 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12697 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12698 it's not optimized away by whole-program optimization.
12699 (message_enable_multibyte, free_misc): Remove.
12700 (catchlist, handlerlist, mark_backtrace):
12701 Declare only if BYTE_MARK_STACK.
12702 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
12703 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
12704 (message_enable_multibyte): Remove decl.
12705 (free_misc, interval_free_list, float_block, float_block_index):
12706 (n_float_blocks, float_free_list, cons_block, cons_block_index):
12707 (cons_free_list, last_marked_index):
12709 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
12710 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12711 (mark_backtrace): Define only if BYTE_MARK_STACK.
12712 * xdisp.c (message_enable_multibyte): Now static.
12714 Declare Lisp_Object Q* variables to be 'static' if not exported.
12715 This makes it easier for human readers (and static analyzers)
12716 to see whether these variables are used from other modules.
12717 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12718 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12719 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
12720 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

12722 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
12723 * xmenu.c, xselect.c:
12724 Declare Q* vars static if they are not used in other modules.
12725 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
12726 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12727 Remove decls of unexported vars.
12728 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12730 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12732 Make Emacs functions such as Fatom 'static' by default.
12733 This makes it easier for human readers (and static analyzers)
12734 to see whether these functions can be called from other modules.
12735 DEFUN now defines a static function. To make the function external
12736 so that it can be used in other C modules, use the new macro DEFUE.
12737 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12738 (Finit_image_library):
12739 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12740 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12741 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12742 Remove decls, since these functions are now static.
12743 (Funintern, Fget_internal_run_time): New decls, since these functions
12744 were already external.
12746 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12747 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
12748 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

12751 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
12752 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
12753 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12754 Mark functions with DEFUE instead of DEFUN,
12755 if they are used in other modules.
12756 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12757 decls for now-static functions.
12758 * buffer.h (Fdelete_overlay): Remove decl.
12759 * callproc.c (Fgetenv_internal): Mark as internal.
12760 * composite.c (Fremove_list_of_text_properties): Remove decl.

12764 * doc.c (Fdocumntation_property): New forward static decl.
12765 * eval.c (Ffetch_bytecode): New forward static decl.
12766 (Funintern): Remove extern decl; now in .h file where it belongs.
12767 * fileio.c (Fmake_symbolic_link): New forward static decl.
12768 * image.c (Finit_image_library): New forward static decl.
12769 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12770 * intervals.h (Fprevious_property_change):
12771 (Fremove_list_of_text_properties): Remove decls.
12772 * keyboard.c (Fthis_command_keys): Remove decl.
12773 (Fcommand_execute): New forward static decl.
12774 * keymap.c (Flookup_key): New forward static decl.
12775 (Fcopy_keymap): Now static.
12776 * keymap.h (Flookup_key): Remove decl.
12777 * process.c (Fget_process): New forward static decl.
12778 (Fprocess_datagram_address): Mark as internal.

12789 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12791 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12794 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12796 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12797 when at ZV. (Bug#8487)
12799 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12801 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12803 * keyboard.c (parse_tool_bar_item): Likewise.
12804 * sound.c (sound_cleanup, alsa_close): Likewise.
12805 * termcap.c (tgetent): Likewise.
12806 * xfns.c (x_default_font_parameter): Likewise.
12807 * xsettings.c (read_and_apply_settings): Likewise.
12809 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12810 (overrun_check_free): Protoize.
12812 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12814 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12815 since callers should never pass a negative size.
12816 Change the signature to match that of plain 'read' and 'write'; see
12817 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12818 * lisp.h: Update prototypes of emacs_write and emacs_read.
12820 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12822 * xdisp.c (redisplay_window): Don't try to determine the character
12823 position of the scroll margin if the window start point w->startp
12824 is outside the buffer's accessible region. (Bug#8468)
12826 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12828 Fix write-region and its subroutines for buffers > 2GB.
12829 * fileio.c (a_write, e_write): Modify declaration of arguments and
12830 local variables to support buffers larger than 2GB.
12831 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12833 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12834 argument, local variables, and return value.
12836 * lisp.h: Update prototypes of emacs_write and emacs_read.
12838 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12840 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12842 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12844 Fix more problems found by GCC 4.6.0's static checks.
12846 * xdisp.c (vmessage): Use a better test for character truncation.
12848 * charset.c (load_charset_map): <, not <=, for optimization,
12849 and to avoid potential problems with integer overflow.
12850 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12851 * casetab.c (set_identity, shuffle): Likewise.
12852 * editfns.c (Fformat): Likewise.
12853 * syntax.c (skip_chars): Likewise.
12855 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12856 This also lets GCC 4.6.0 generate slightly better loop code.
12858 * callint.c (Fcall_interactively): <, not <=, for optimization.
12859 (Fcall_interactively): Count the number of arguments produced,
12860 not the number of arguments given. This is simpler and lets GCC
12861 4.6.0 generate slightly better code.
12863 * ftfont.c: Distingish more carefully between FcChar8 and char.
12864 The previous code passed unsigned char * to a functions like
12865 strlen and xstrcasecmp that expect char *, which does not
12866 conform to the C standard.
12867 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12868 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12869 char * when the C standard requires it.
12871 * keyboard.c (read_char): Remove unused var.
12873 * eval.c: Port to Windows vsnprintf (Bug#8435).
12874 Include <limits.h>.
12875 (SIZE_MAX): Define if the headers do not.
12876 (verror): Do not give up if vsnprintf returns a negative count.
12877 Instead, grow the buffer. This ports to Windows vsnprintf, which
12878 does not conform to C99. Problem reported by Eli Zaretskii.
12879 Also, simplify the allocation scheme, by avoiding the need for
12880 calling realloc, and removing the ALLOCATED variable.
12882 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12884 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12885 But keep the doprint source code for now, as we might revamp it
12886 and use it again (Bug#8435).
12887 * lisp.h (doprnt): Remove.
12888 * Makefile.in (base_obj): Remove doprnt.o.
12889 * deps.mk (doprnt.o): Remove.
12891 error: Print 32- and 64-bit integers portably (Bug#8435).
12892 Without this change, on typical 64-bit hosts error ("...%d...", N)
12893 was used to print both 32- and 64-bit integers N, which relied on
12894 undefined behavior.
12895 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12896 * lisp.h (error, verror): Mark as printf-like functions.
12897 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12898 Report overflow in size calculations when allocating printf buffer.
12899 Do not truncate output string at its first null byte.
12900 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12901 Truncate the output at a character boundary, since vsnprintf does not
12903 * charset.c (check_iso_charset_parameter): Convert internal
12904 character to string before calling 'error', since %c now has the
12906 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12907 overflow when computing char to be passed to 'error'. Do not
12908 pass Lisp_Object to 'error'; pass the integer instead.
12909 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12910 formatted with plain %d.
12912 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12914 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12916 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12918 * xterm.c (x_catch_errors): Remove duplicate declaration.
12920 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12922 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12924 2011-04-10 Jim Meyering <meyering@redhat.com>
12926 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12927 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12928 return ssize_t not "int", and use size_t as the buffer length.
12929 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12930 * gnutls.h: Update declarations.
12931 * process.c (read_process_output): Use ssize_t, to match.
12932 (send_process): Likewise.
12934 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12936 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12938 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12940 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12941 Use unsigned char, to match FcChar8 type definition.
12943 * xterm.c (handle_one_xevent):
12944 * xmenu.c (create_and_show_popup_menu):
12945 * xselect.c (x_decline_selection_request)
12946 (x_reply_selection_request): Avoid type-punned deref of X events.
12948 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12950 Fix some uses of `int' instead of EMACS_INT.
12951 * search.c (string_match_1, fast_string_match)
12952 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12953 (scan_buffer, find_next_newline_no_quit)
12954 (find_before_next_newline, search_command, Freplace_match)
12955 (Fmatch_data): Make some `int' variables be EMACS_INT.
12957 * xdisp.c (display_count_lines): 3rd argument and return value now
12958 EMACS_INT. All callers changed.
12959 (pint2hrstr): Last argument is now EMACS_INT.
12961 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12962 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12963 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12964 (decode_coding_utf_16, decode_coding_emacs_mule)

12966 (decode_coding_ccl, decode_coding_charset)
12967 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

12974 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12975 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12977 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12978 (encode_invocation_designation): Last argument P_NCHARS is now
12980 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12981 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12983 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12986 * ccl.c (Fccl_execute_on_string): Declare some variables
12989 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12991 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12993 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12995 * process.c (Fformat_network_address): Doc fix.
12997 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12999 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13001 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13003 * keyboard.c (read_char): Call Lisp function help-form-show,
13004 instead of using internal_with_output_to_temp_buffer.
13005 (Qhelp_form_show): New var.
13006 (syms_of_keyboard): Use DEFSYM macro.
13008 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13015 (list_processes_1): Delete.
13017 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13019 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13021 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13023 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13025 Fix more problems found by GCC 4.6.0's static checks.
13027 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13029 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13031 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13033 * xdisp.c (vmessage): Mark as a printf-like function.
13035 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13037 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13039 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13040 printf-like functions.
13041 (tiff_load): Add casts to remove these marks before passing them
13042 to system-supplied API.
13044 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13046 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13047 This avoids several warnings with gcc -Wstrict-overflow.
13048 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13049 directly, rather than having caller test rule sign. This avoids
13050 some unnecessary tests.
13051 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13052 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13053 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13055 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13056 (xfont_open): Avoid unnecessary tests.
13058 * composite.c (composition_gstring_put_cache): Use unsigned integer.

13067 by using the new macro.
13069 * textprop.c (set_text_properties_1): Change while to do-while,
13070 since the condition is always true at first.
13072 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13073 (interval_deletion_adjustment): Return unsigned value.
13076 * process.c (list_processes_1, create_pty, read_process_output):
13077 (exec_sentinel): Remove vars that were set but not used.
13078 (create_pty): Remove unnecessary "volatile"s.

13090 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13092 * print.c (print_error_message): Avoid int overflow.
13094 * font.c (font_list_entities): Redo for clarity,
13095 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

13105 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13106 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13107 can always succeed if overflow has undefined behavior.
13109 * search.c (boyer_moore, wordify): Remove vars set but not used.
13110 (wordify): Omit three unnecessary tests.
13112 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13113 All callers changed. This avoids the need for an unused var.
13115 * casefiddle.c (casify_region): Remove var that is set but not used.
13117 * dired.c (file_name_completion): Remove var that is set but not used.
13119 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13121 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13122 (Finsert_file_contents): Remove unnecessary code checking fd.
13124 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13125 Check for integer overflow on size calculations.
13127 * buffer.c (Fprevious_overlay_change): Remove var that is set
13130 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13131 Remove vars that are set but not used.
13132 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13133 (timer_check_2): Mark vars as initialized.
13135 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13137 * image.c (lookup_image): Remove var that is set but not used.
13138 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13140 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13141 that are set but not used.
13143 * xfns.c (make_invisible_cursor): Don't return garbage
13144 if XCreateBitmapFromData fails (Bug#8410).
13146 * xselect.c (x_get_local_selection, x_handle_property_notify):
13147 Remove vars that are set but not used.
13149 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13150 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13152 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13153 Remove var that is set but not used.
13154 (scroll_bar_windows_size): Now size_t, not int.
13155 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13156 Check for overflow.
13158 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13159 (map_tty_color) [!defined MSDOS]: Likewise.
13161 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13163 * coding.c: Remove vars that are set but not used.
13164 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13165 All callers changed.
13166 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13167 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13168 (decode_coding_charset): Remove vars that are set but not used.
13170 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13171 that is set but not used.
13173 * print.c (print_object): Remove var that is set but not used.
13175 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13176 The gnulib version avoids calling malloc in the usual case,
13177 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13178 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13179 * filelock.c (current_lock_owner): Likewise.
13180 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13181 * sysdep.c: Include allocator.h, careadlinkat.h.
13182 (emacs_no_realloc_allocator): New static constant.
13183 (emacs_readlink): New function.
13184 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13185 ../lib/careadlinkat.h.
13187 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13189 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13190 first non-nil return value).

13199 * xdisp.c (display_count_lines): Remove parameter `start',
13200 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13201 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13202 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13204 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13205 and thereabouts. All callers changed.
13206 (get_per_char_metric): Remove parameter `f', unused since
13207 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13209 2011-04-02 Jim Meyering <meyering@redhat.com>
13211 do not dereference NULL upon failed strdup
13212 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13213 (ns_get_family): Likewise.
13215 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13217 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13219 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13221 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13224 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13226 Add lexical binding.
13228 * window.c (Ftemp_output_buffer_show): New fun.
13229 (Fsave_window_excursion):
13230 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13232 * lread.c (lisp_file_lexically_bound_p): New function.
13233 (Fload): Bind Qlexical_binding.
13234 (readevalloop): Remove `evalfun' arg.
13235 Bind Qinternal_interpreter_environment.
13236 (Feval_buffer): Bind Qlexical_binding.
13237 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13239 (syms_of_lread): Declare `lexical-binding'.
13241 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13243 * keyboard.c (eval_dyn): New fun.
13244 (menu_item_eval_property): Use it.
13246 * image.c (parse_image_spec): Use Ffunctionp.
13248 * fns.c (concat, mapcar1): Accept byte-code-functions.
13250 * eval.c (Fsetq): Handle lexical vars.
13251 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13252 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13253 (FletX, Flet): Obey lexical binding.
13254 (Fcommandp): Handle closures.
13255 (Feval): New `lexical' arg.
13256 (eval_sub): New function extracted from Feval. Use it almost
13257 everywhere where Feval was used. Look up vars in lexical env.
13259 (Ffunctionp): Move from subr.el.
13260 (Ffuncall): Handle closures.
13261 (apply_lambda): Remove `eval_flags'.
13262 (funcall_lambda): Handle closures and new byte-code-functions.
13263 (Fspecial_variable_p): New function.
13264 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13265 but without exporting it to Lisp.
13267 * doc.c (Fdocumentation, store_function_docstring):
13268 * data.c (Finteractive_form): Handle closures.
13270 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13273 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13275 (exec_byte_code): New function extracted from Fbyte_code to handle new
13276 calling convention for byte-code-functions. Add new byte-codes.
13278 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13280 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13282 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13284 * xdisp.c (redisplay_internal): Fix prototype.
13286 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13288 * xdisp.c (SCROLL_LIMIT): New macro.
13289 (try_scrolling): Use it when setting scroll_limit.
13290 Limit scrolling to 100 screen lines.
13291 (redisplay_window): Even when falling back on "recentering",
13292 position point in the window according to scroll-conservatively,
13293 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13295 (try_scrolling): When point is above the window, allow searching
13296 as far as scroll_max, or one screenful, to compute vertical
13297 distance from PT to the scroll margin position. This prevents
13298 try_scrolling from unnecessarily failing when
13299 scroll-conservatively is set to a value slightly larger than the
13300 window height. Clean up the case of PT below the margin at bottom
13301 of window: scroll_max can no longer be INT_MAX. When aggressive
13302 scrolling is in use, don't let point enter the opposite scroll
13303 margin as result of the scroll.
13304 (syms_of_xdisp) <scroll-conservatively>: Document the
13305 threshold of 100 lines for never-recentering scrolling.
13307 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

13312 (message_log_check_duplicate): Remove parameters `prev_bol' and
13313 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13314 (redisplay_internal): Remove parameter `preserve_echo_area',
13315 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13317 * indent.c (Fvertical_motion):
13318 * window.c (window_scroll_pixel_based, Frecenter):
13319 Don't pass `need_y_p' to `move_it_by_lines'.
13321 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13323 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13324 steal a few bits to be more compact.
13325 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13326 Remove unneeded casts.
13328 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13330 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13332 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13333 binding" message (bug#7967).
13335 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13337 Fix more problems found by GCC 4.6.0's static checks.
13339 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13340 Remove unused local var.
13342 * editfns.c (Fmessage_box): Remove unused local var.
13344 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13345 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13346 Omit unused local vars.
13347 * window.c (shrink_windows): Omit unused local var.
13348 * menu.c (digest_single_submenu): Omit unused local var.
13349 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13350 Omit unused local var.
13352 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13353 Don't assume string length fits in int.
13354 (keyremap_step, read_key_sequence): Use size_t for sizes.
13355 (read_key_sequence): Don't check last_real_key_start redundantly.
13357 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13358 instead of alloca (Bug#8344).
13360 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13361 (Fbacktrace_frame): Don't assume nframes fits in int.
13363 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13365 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13368 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13370 * cm.c (calccost): Turn while-do into do-while, for clarity.
13372 * keyboard.c (syms_of_keyboard): Use the same style as later
13373 in this function when indexing through an array. This also
13374 works around GCC bug 48267.
13376 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13378 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13380 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13381 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13383 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13384 This avoids undefined behavior on integer overflow, and is a bit
13385 more convenient anyway since it is compared to a size_t variable.
13387 Variadic C functions now count arguments with size_t, not int.
13388 This avoids an unnecessary limitation on 64-bit machines, which
13389 caused (substring ...) to crash on large vectors (Bug#8344).
13390 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13391 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13399 * fns.c (concat): Likewise.
13400 * frame.c (x_set_frame_parameters): Likewise.
13401 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13402 0 if not found, not -1. All callers changed.
13404 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13405 (stack_copy_size): Now size_t, not int.
13406 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13408 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13410 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13411 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13412 All callers changed.
13414 * lisp.h (multibyte_char_to_unibyte):
13415 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13416 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13427 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13428 don't set the hook to nil, but remove the offending function instead.
13429 (Qcommand_hook_internal): Remove, unused.
13430 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13431 Vcommand_hook_internal.
13433 * eval.c (enum run_hooks_condition): Remove.
13434 (funcall_nil, funcall_not): New functions.
13435 (run_hook_with_args): Call each function through a `funcall' argument.

13449 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13450 All callers changed.
13452 * w32.c (_wsa_errlist): Use braces for struct initializers.
13454 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

13599 2011-03-23 Julien Danjou <julien@danjou.info>
13601 * term.c (Fsuspend_tty, Fresume_tty):
13602 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13603 * window.c (temp_output_buffer_show):
13604 * insdel.c (signal_before_change):
13605 * frame.c (Fhandle_switch_frame):
13606 * fileio.c (Fdo_auto_save):

13610 * callint.c (Fcall_interactively):
13611 * buffer.c (Fkill_all_local_variables):
13612 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13614 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13615 unconditionally since it does the check itself.
13617 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13619 Fix more problems found by GCC 4.5.2's static checks.
13621 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13622 the first time through the loop, since we know p0 < p1 then.
13623 This also avoids a gcc -Wstrict-overflow warning.
13625 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13626 leading to a memory leak, possible in functions like
13627 load_charset_map_from_file that can allocate an unbounded number
13628 of objects (Bug#8318).
13630 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13631 that could (at least in theory) be that large.
13633 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13634 This is less likely to overflow, and avoids undefined behavior if
13635 overflow does occur. All callers changed. Use strtoul to scan
13636 for the unsigned long integer.
13637 (pint2hrstr): Simplify and tune code slightly.
13638 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13640 * scroll.c (do_scrolling): Work around GCC bug 48228.
13641 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13643 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13644 This also avoids a warning with gcc -Wstrict-overflow.
13645 (validate_x_resource_name): Simplify count usage.
13646 This also avoids a warning with gcc -Wstrict-overflow.
13648 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13651 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13653 * process.c (Fmake_network_process): Use socklen_t, not int,
13654 where POSIX says socklen_t is required in portable programs.
13655 This fixes a porting bug on hosts like 64-bit HP-UX, where
13656 socklen_t is wider than int (Bug#8277).
13657 (Fmake_network_process, server_accept_connection):
13658 (wait_reading_process_output, read_process_output):
13661 * process.c: Rename or move locals to avoid shadowing.

13671 Make tparam.h and terminfo.c consistent.
13672 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13673 Include tparam.h instead, since it declares them.
13674 * cm.h (PC): Remove extern decl; tparam.h now does this.
13675 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13676 * terminfo.c: Include tparam.h, to check interfaces.
13677 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13678 (tparam): Adjust signature to match interface in tparam.h;
13679 this removes some undefined behavior. Check that outstring and len
13680 are zero, which they always are with Emacs.
13681 * tparam.h (PC, BC, UP): New extern decls.
13683 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13684 (xftfont_open): Rename locals to avoid shadowing.
13686 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13687 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

13696 * xml.c (make_dom): Now static.
13698 * composite.c (composition_compute_stop_pos): Rename local to
13700 (composition_reseat_it): Remove unused locals.
13701 (find_automatic_composition, composition_adjust_point): Likewise.
13702 (composition_update_it): Mark var as initialized.
13703 (find_automatic_composition): Mark vars as initialized,
13704 with a FIXME (Bug#8290).

13707 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13708 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13709 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13710 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13711 to avoid shadowing.
13713 * textprop.c (property_change_between_p): Remove; unused.
13715 * intervals.c (interval_start_pos): Now static.
13717 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13720 Rename locals to avoid shadowing.
13722 * sound.c (wav_play, au_play, Fplay_sound_internal):
13723 Fix pointer signedness.
13724 (alsa_choose_format): Remove unused local var.
13725 (wav_play): Initialize a variable to 0, to prevent undefined
13726 behavior (Bug#8278).
13728 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13730 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13732 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13733 clobbering (Bug#8298).
13734 * sysdep.c (sys_subshell): Likewise.
13735 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13737 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13738 This should get cleaned up, so that child_setup has the
13739 same signature on all platforms.
13741 * callproc.c (call_process_cleanup): Now static.
13742 (relocate_fd): Rename locals to avoid shadowing.
13744 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13746 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13747 not to be necessary, and produces flickering.
13749 2011-03-20 Glenn Morris <rgm@gnu.org>
13751 * config.in: Remove file.
13753 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13755 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13756 are now in src/globals.h.
13757 (syms_of_minibuf): Remove spurious & from previous change.
13759 2011-03-20 Leo Liu <sdl.web@gmail.com>
13761 * minibuf.c (completing-read-function): New variable.
13762 (completing-read-default): Rename from completing-read.
13763 (completing-read): Call completing-read-function.
13765 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13767 * xfaces.c (Fx_load_color_file):
13768 Read color file from absolute filename (bug#8250).
13770 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13772 * makefile.w32-in: Update dependencies.
13774 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13776 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13783 (sigchld_handler): Now static.
13785 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13786 That way, the code declares only the vars that it needs.
13787 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13788 * s/cygwin.h (PTY_ITERATION): Likewise.
13789 * s/darwin.h (PTY_ITERATION): Likewise.

13796 (CONSTANTLIM): Remove; unused.
13797 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13798 Define only if needed.
13800 * unexelf.c (unexec): Name an expression,
13801 to avoid gcc -Wbad-function-cast warning.
13802 Use a different way to cause a compilation error if anyone uses
13803 n rather than nn, a way that does not involve shadowing.
13804 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13806 * deps.mk (unexalpha.o): Remove; unused.
13808 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13809 * unexec.h: New file.
13810 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13811 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13812 Depend on unexec.h.
13813 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13814 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13815 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
13816 Change as necessary to match prototype in unexec.h.
13818 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
13820 (back_comment, skip_chars): Mark vars as initialized.

13871 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13872 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13873 some of which prompt warnings from gcc -Wbad-function-cast.
13874 (Fformat_time_string, Fencode_time, Finsert_char):
13875 (Ftranslate_region_internal, Fformat):
13876 Rename or remove local vars to avoid shadowing.
13877 (Ftranslate_region_internal): Mark var as initialized.
13879 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13882 * lisp.h (eassert): Check that the argument compiles, even if
13883 ENABLE_CHECKING is not defined.
13885 * data.c (Findirect_variable): Name an expression, to avoid
13886 gcc -Wbad-function-cast warning.

13895 Rename locals to avoid shadowing.
13896 (mark_stack): Move local variables into the #ifdef region where
13898 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13899 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13901 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13902 (GC_STRING_CHARS): Remove; not used.
13903 (Fmemory_limit): Cast sbrk's returned value to char *.
13905 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

13911 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13912 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13913 to use the following functions instead of these macros.
13914 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13915 EMACS_INT, since callers assume the returned value fits in int.
13916 (upcase1): Likewise, for UPCASE_TABLE.
13917 (uppercasep, lowercasep, upcase): New static inline functions.
13918 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13922 Rename locals to avoid shadowing.
13923 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13924 (regex_compile, re_search_2, re_match_2_internal):
13925 Remove unused local vars.
13926 (FREE_VAR): Rewrite so as not to use empty "else",
13927 which gcc can warn about.
13928 (regex_compile, re_match_2_internal): Mark locals as initialized.
13929 (RETALLOC_IF): Define only if needed.
13930 (WORDCHAR_P): Likewise. This one is never needed, but is used
13931 only in a comment talking about a compiler bug, so put inside
13932 the #if 0 of that comment.
13933 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13934 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13937 * search.c (boyer_moore): Rename locals to avoid shadowing.
13938 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
13939 (PREV_CHAR_BOUNDARY): Likewise.
13941 * search.c (simple_search): Remove unused var.
13943 * dired.c (compile_pattern): Move decl from here ...

13951 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13952 Rename locals to avoid shadowing.
13953 (Fvertical_motion): Mark locals as initialized.
13955 * casefiddle.c (casify_object, casify_region): Now static.
13956 (casify_region): Mark local as initialized.
13958 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13960 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13961 New macros, so that the caller can use some names other than
13962 gcpro1, gcpro2, etc.
13963 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13965 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13966 argument, for consistency with GCPRO2_VAR, etc: it is now the
13967 prefix of the variable, not the variable itself. All uses
13969 * dired.c (directory_files_internal, file_name_completion):
13970 Rename locals to avoid shadowing.
13972 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13973 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13974 dired.c's scmp function, had undefined behavior.
13975 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13976 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13977 * buffer.h: ... to here, because these macros use current_buffer,
13978 and the new implementation with inline functions needs to have
13979 current_buffer in scope now, rather than later when the macros
13981 (downcase, upcase1): New static inline functions.
13982 (DOWNCASE, UPCASE1): Reimplement using these functions.
13983 This avoids undefined behavior in expressions like
