65 does that unconditionally. Remove file, which is now empty.
67 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
70 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

221 2012-07-27 Eli Zaretskii <eliz@gnu.org>
223 * alloc.c (listn): Fix the order the arguments are consed onto the
226 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
227 enumeration constants, as PURE and HEAP are too general, and clash
228 with other headers and sources, such as gmalloc.c and the
229 MS-Windows system headers. All users changed.
231 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
233 Revert last save_excursion_save and save_excursion_restore changes.
234 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

246 Improve GDB symbol export (Bug#12036).
247 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
248 arms of an 'if', not using conditional expressions; otherwise GDB
249 complains about the types in the unevaluated arm when the argument
250 is an integer literal.
251 (xgetint): Simplify expression.
252 * alloc.c (gdb_make_enums_visible): New constant. This ports to
253 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
254 Zaretskii in <http://bugs.gnu.org/12036#13>.
255 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
256 needed now that we have gdb_make_enums_visible.

301 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
302 emacs.c, as this is a more-suitable home. Had this been done earlier
303 the fix for 12036 would have avoided some of the problems noted in
304 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
305 would have been more obvious.
306 * emacs.c: Do not include <verify.h>; no longer needed.
307 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
308 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)

315 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
316 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
317 not be usable in #if. This simplifies things.
319 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
321 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
323 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

326 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
327 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
328 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
329 Adjust to changes in lisp.h and emacs.c, by using
330 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
331 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
332 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
333 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
334 instead of gdb_valbits.
335 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
336 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
337 instead of gdb_array_mark_flag.
338 (xboolvector): Get size from $->size, not $->header.size.
339 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
340 (xreload, hook-run, hookpost-run): Remove.
341 * emacs.c: Include <verify.h>.
342 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
343 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
345 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
346 (gdb_USE_LSB_TAG): New enum constants.
347 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
348 Also define these as enum constants, so they're visible to GDB.
349 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
350 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
351 as constants, so they're visible to GDB.
352 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
353 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
354 Now enum constants, not macros, so they're visible to GDB.
355 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
356 more convenient now. All uses changed.
357 (VALMASK) [USE_LSB_TAG]: Also define in this case.

368 add argument, tune behavior, and adjust all callers.
370 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
372 Use typedef for EMACS_INT, EMACS_UINT.
373 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
374 than macros. This simplifies debugging in the usual case, since
375 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
376 and it allows expressions involving EMACS_INT casts.
377 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
379 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
381 * nsterm.m (ns_read_socket): Return early if there is a modal

391 Adjust buffer text indirection counters at the end of Fkill_buffer.
392 * buffer.c (Fkill_buffer): Adjust indirection counters when the
393 buffer is definitely dead. This should really fix an issue reported
394 by Christoph Scholtes again. (Bug#12007).
395 (init_buffer_once): Initialize indirection counters of
396 buffer_defaults and buffer_local_symbols (for sanity and safety).
398 2012-07-24 Eli Zaretskii <eliz@gnu.org>
400 * xdisp.c (init_iterator): Don't compute dimensions of truncation
401 and continuation glyphs on tooltip frames, leave them at zero.
402 Avoids continued lines in tooltips. (Bug#11832)
404 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
406 Simplify copy_overlay.
407 * buffer.c (copy_overlay): Simplify. Use build_marker.

413 or invalid. (Bug#12025)
415 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
416 it signals an error when a tooltip frame is being created.
418 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

429 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
431 Swap buffer text indirection counters in Fbuffer_swap_text.
432 * buffer.c (Fbuffer_swap_text): Swap indirections too.
433 This avoids crash reported by Christoph Scholtes at
434 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
436 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
438 * nsmenu.m (Popdown_data): New struct.
439 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
441 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
442 (initWithContentRect): Make imgView and contentView non-static
443 and autorelease them. Also autorelease img and matrix (Bug#12005).
444 (dealloc): Remove (Bug#12005).
446 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
448 Adjust consing_since_gc when objects are explicitly freed.
449 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
450 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

1192 * s/aix4-2.h (unix): Remove; no longer needed.
1194 EMACS_TIME simplification (Bug#11875).
1195 This replaces macros (which typically do not work in GDB)

1197 The functional style also makes code easier to read and maintain.
1198 * systime.h: Include <sys/time.h> on all hosts, not just if
1199 WINDOWSNT, since 'struct timeval' is needed in general.

1239 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1240 Prefer snprintf to strncpy.
1241 * nsterm.m (ns_term_init):
1242 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1243 * nsterm.m (ns_term_init):
1244 Avoid the need for strncpy, by using build_string or
1245 make_unibyte_string directly. Use dtoastr, not snprintf.
1246 * process.c (Fmake_network_process): Diagnose service names that
1247 are too long, rather than silently truncating them or creating
1248 non-null-terminated names.

1265 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1266 where argument type is known to be a Lisp_Cons.

1321 O_RDONLY already includes it).
1323 Stop ns builds setting the EMACSLOADPATH environment variable.
1324 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1325 Now it does not set EMACSLOADPATH, just returns the load-path string.
1326 * nsterm.h: Update accordingly.
1327 * lread.c [HAVE_NS]: Include nsterm.h.
1328 (init_lread) [HAVE_NS]: Use ns_load_path.

1338 (ns_init_paths): Do not set EMACSPATH.

1391 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1392 * nsterm.h (ns_etc_directory): Add it.
1393 * callproc.c [HAVE_NS]: Include nsterm.h.
1394 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1396 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1398 Move marker debugging code under MARKER_DEBUG.
1399 * marker.c (MARKER_DEBUG): Move marker debugging code under
1400 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1401 for bootstrap with --enable-checking (~3x slowdown reported
1402 by Juanma Barranquero <lekktu@gmail.com>).
1403 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1405 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1407 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1408 See <http://bugs.gnu.org/11825#29>.
1410 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1412 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1413 has no font, use the frame's font. (Bug#11813)
1414 (display_line): Add commentary about displaying truncation glyphs
1416 (produce_special_glyphs): Move here from term.c.
1418 * term.c (produce_special_glyphs): Move to xdisp.c.
1420 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1423 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1425 * xdisp.c (display_line): Avoid warning about implicit declaration
1428 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1430 * lisp.h: Remove empty conditional.
1432 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1434 * lread.c (load_path_check): Now static.
1436 Fix some minor --with-ns problems found by static checking.
1437 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1438 (x_set_font) [!HAVE_X_WINDOWS]:
1439 * image.c (xpm_load_image) [HAVE_NS]:
1440 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1441 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1442 Remove unused local.
1443 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1444 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1445 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1446 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1447 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):

1449 Fix pointer signedness problem.
1450 * xfaces.c (FRAME_X_FONT_TABLE):
1451 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1453 2012-07-07 Glenn Morris <rgm@gnu.org>
1455 * lread.c (load_path_check): New function, split from init_lread.
1456 (init_lread): Reorganize. Motivation:
1457 If EMACSLOADPATH is set, check/warn about that rather than the
1458 defaults, which we are not going to use. Hence we can remove
1459 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1460 Don't warn if site-lisp directories are missing.
1461 If not installed, start from a blank load-path, since
1462 PATH_LOADSEARCH refers to the eventual installation directories.
1464 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1466 Support truncation and continuation glyphs on GUI frames, when
1467 fringes are disabled. (Bug#11832)
1468 * xdisp.c (init_iterator): Get dimensions of truncation and
1469 continuation glyphs even if on GUI frames. Adjust
1470 it->last_visible_x on GUI frames when the left or right fringes,
1471 or both, are absent.
1472 (start_display, move_it_in_display_line_to): Handle the case of a
1473 GUI frame without a fringe to display continuation or truncation
1475 (insert_left_trunc_glyphs): Support GUI frames: make sure
1476 truncation glyphs overwrite enough glyphs from the current line to
1477 have sufficient space in pixels.
1478 (display_line): Support truncation and continuation glyphs on GUI
1479 frames. If some spare pixels are left on the line after inserting
1480 the truncation glyphs, fill that space with a stretch glyph of a
1481 suitably computed width.
1483 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1484 produce_glyphs, to support GUI sessions.
1486 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1488 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1490 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1492 Do not require float-time's arg to fit in time_t (Bug#11825).
1493 This works better on hosts where time_t is unsigned, and where
1494 float-time is applied to the (negative) difference between two times.
1495 * editfns.c (decode_time_components): Last arg is now double *,
1496 not int *, and means to store all the result as a double, without
1497 worrying about whether the seconds part fits in time_t.
1498 All callers changed.
1499 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1500 All callers changed.
1501 (Ffloat_time): Do not fail merely because the specified time falls
1502 outside of time_t range.
1504 2012-07-07 Glenn Morris <rgm@gnu.org>
1506 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1512 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1513 Update dependencies.
1515 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1517 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1519 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1520 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1521 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1522 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1523 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1524 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1526 * xfont.c (compare_font_names): Redo to omit the need for casts.
1528 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1530 * xfns.c (Fx_change_window_property): Doc fix.
1531 * w32fns.c (Fx_change_window_property): Doc fix.
1533 * w32fns.c (Fx_window_property): Accept the same arguments as the
1534 X Windows version. Doc fix.
1535 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1537 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1538 Eli Zaretskii <eliz@gnu.org>
1540 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1541 Windows-specific code from nt/config.nt moved here.
1542 Obsolete settings removed.
1544 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1546 * process.c: Avoid unnecessary calls to gettime.
1547 (wait_reading_process_output): Don't get the time of day
1548 when gobbling data immediately and not waiting, as there's no need
1549 for it in that case. This removes a FIXME.
1551 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1553 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1554 is defined (Bug#11768).
1556 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1558 Fix marker debugging code.
1559 * marker.c (byte_char_debug_check): Do not perform the check
1560 if buffer is not multibyte.
1561 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1562 Call byte_char_debug_check with correct arguments.
1564 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1566 Compile marker debugging code only if ENABLE_CHECKING is defined.
1567 * marker.c (byte_char_debug_check, count_markers):
1568 Use only if ENABLE_CHECKING is defined.
1569 (byte_debug_flag): Remove.
1570 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1571 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1573 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1575 Avoid code repetition in marker-related functions.
1576 * marker.c (attach_marker): New function.
1577 (Fset_marker, set_marker_restricted, set_marker_both)
1578 (set_marker_restricted_both): Use it.
1579 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1580 Consistently rename charno to charpos.
1581 (marker_position): Add eassert.
1582 (marker_byte_position): Convert to eassert.
1584 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1586 Simplify list operations in unchain_overlay and unchain_marker.

1594 * lisp.h (build_marker): New prototype.
1595 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1596 * composite.c (autocmp_chars): Likewise.
1597 * editfns.c (buildmark): Remove.
1598 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1599 (save_restriction_save): Use build_marker.
1600 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1601 * window.c (save_window_save): Likewise.
1603 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1605 Do not use Fdelete_overlay in delete_all_overlays
1606 to avoid redundant calls to unchain_overlay.
1607 * buffer.c (drop_overlay): New function.
1608 (delete_all_overlays, Fdelete_overlay): Use it.
1609 * minibuf.c (get_minibuffer): Fix comment.
1611 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1613 Port to OpenBSD 5.1 amd64.
1614 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1615 This is needed for OpenBSD, and should be harmless on all BSD systems.
1616 Also, include <sys/sysctl.h>, as it should be available on all
1617 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1618 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1619 use p_pid member, not kp_proc.pid.
1621 2012-07-06 Glenn Morris <rgm@gnu.org>
1623 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1625 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1627 More xmalloc and related cleanup.
1628 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1629 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

1634 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
1635 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1636 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1638 Omit needless casts involving void * pointers and allocation.
1639 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1640 as the former is more robust if P's type is changed.
1641 Prefer xzalloc to xmalloc + memset 0.
1642 Simplify malloc-or-realloc to realloc.
1643 Don't worry about xmalloc returning a null pointer.
1644 Prefer xstrdup to xmalloc + strcpy.
1645 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1647 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1648 alloca of a constant.
1650 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1652 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1653 hscroll is larger than the line width. Fixes long and futile
1654 looping inside extend_face_to_end_of_line (on a TTY) producing
1655 glyphs that are not needed and thrown away.
1657 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1659 * marker.c (set_marker_restricted_both): Simplify by using
1662 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1664 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1666 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1668 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is

1671 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1672 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1673 followed by gtk_box_set_homogeneous (Bug#11768).
1674 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1675 (update_theme_scrollbar_width, xg_create_scroll_bar):
1676 Use gtk_scrollbar_new (Bug#11768).
1677 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1678 (is_box_type): New function (Bug#11768).
1679 (xg_tool_item_stale_p): Call is_box_type.
1680 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1681 with default display (Bug#11768).
1683 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1685 * xdisp.c (window_hscroll_limited): New function.
1686 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1687 coordinates when window's hscroll is set to insanely large
1690 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1692 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1693 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1695 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1698 * lisp.h (xzalloc): New prototype. Omit needless casts.
1699 * alloc.c (xzalloc): New function. Omit needless casts.

1751 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1753 * fileio.c (time_error_value): Check the right error number.
1754 Problem reported by Troels Nielsen in
1755 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1757 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1759 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1760 This should be fixed in a better way; see Eli Zaretskii in
1761 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1762 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1764 * fileio.c (time_error_value): Rename from special_mtime.
1765 The old name's problems were noted by Eli Zaretskii in
1766 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1768 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1769 This variable's comment says Emacs needs at least one GDB-visible
1770 symbol of type enum pvec_type, to work around GDB problems.
1771 The symbol's value doesn't matter.
1773 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1774 that causes compilation to fail on pre-C99 compilers.
1776 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1778 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1779 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1781 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1783 * buffer.c (init_buffer_once): Fix initialization of
1784 headers for buffer_defaults and buffer_local_symbols.
1785 Reported by Juanma Barranquero <lekktu@gmail.com>.
1787 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1789 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1790 * lisp.h (enum pvec_type): Use fewer bits.
1791 (PSEUDOVECTOR_SIZE_BITS): New constant.
1792 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1793 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1794 change in pvec_type.
1795 (PSEUDOVECTOR_TYPEP): New macro.
1796 (TYPED_PSEUDOVECTORP): Use it.
1797 * fns.c (internal_equal): Adapt code to extract pvectype.
1798 * emacs.c (gdb_pvec_type): Update type.
1799 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1800 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1801 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1802 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1803 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1804 abusing vector->header.next.nbytes.
1805 (live_vector_p): Use PVEC_TYPE.
1806 (mark_object): Adapt code to extract pvectype. Use switch.
1808 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1810 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1811 Tighten new eassert a bit.
1813 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1815 Fix compilation with --enable-gcc-warnings and -O1
1817 * doprnt.c (doprnt): Change type of tem to int, initialize
1818 to avoid compiler warning. Add eassert.
1819 * search.c (simple_search): Initialize match_byte to avoid
1820 compiler warning. Add eassert.
1822 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1824 Avoid weird behavior with large horizontal scrolls.
1825 Without this change, for example, large hscroll values would
1826 mess up Emacs's display on Fedora 15 x86, presumably due to
1827 overflows in int calculations in the display code.
1828 Also, if buffers had long lines, Emacs would freeze.
1829 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1830 (set_window_hscroll): New function, containing the old guts of
1831 Fset_window_hscroll. Return the clipped value.
1832 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1833 This avoids the need to check against PTRDIFF_MAX.
1835 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1837 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1839 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1841 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1843 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1844 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1845 since GCC 4.4.6 issues a bogus warning for them.
1847 Fix bugs in file timestamp newness comparisons.
1848 * fileio.c (Ffile_newer_than_file_p):
1849 * lread.c (Fload): Use full timestamp resolution of files,
1850 not just the 1-second resolution, so that files that are only
1851 slightly newer still count as newer.
1852 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1853 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1855 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1857 * fileio.c: Improve handling of file time marker. (Bug#11852)
1858 (special_mtime): New function.
1859 (Finsert_file_contents, Fverify_visited_file_modtime):
1860 Use it to set special mtime values consistently.
1862 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1864 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1865 marker for non-existing file. (Bug#11852)
1867 2012-07-03 Glenn Morris <rgm@gnu.org>
1869 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1870 and did not make it into globals.h).
1872 2012-07-03 Tom Tromey <tromey@redhat.com>
1874 * window.c (Fset_window_margins, Fset_window_fringes)
1875 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1876 * textprop.c (Fprevious_property_change): No longer static.

1899 * intervals.h: Remove EXFUNs.
1900 * fontset.h: Remove EXFUN.
1901 * font.h: Remove EXFUNs.
1902 * dosfns.c (system_process_attributes): Remove EXFUN.
1903 * keymap.h: Remove EXFUNs.
1904 * lisp.h: Remove EXFUNs.
1905 * w32term.h: Remove EXFUNs.
1906 * window.h: Remove EXFUNs.
1907 * xsettings.h: Remove EXFUN.
1908 * xterm.h: Remove EXFUN.
1910 2012-07-03 Glenn Morris <rgm@gnu.org>
1912 * lisp.h (Frandom): Make it visible to C.
1913 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1914 buffer for invisible buffers. (Bug#1229)
1916 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1918 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1919 values which aren't power of 2.
1920 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1921 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1924 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1926 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1928 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1930 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1932 * alloc.c (allocate_vector_block): Remove redundant
1933 calls to mallopt if DOUG_LEA_MALLOC is defined.
1934 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1935 avoid calls to mallopt if zero_vector is returned.
1937 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1939 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1940 is enabled, avoid dereferencing NULL current_sblock if
1943 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1945 Cleanup basic buffer management.
1946 * buffer.h (struct buffer): Change layout to use generic vector
1947 marking code. Fix some comments. Change type of 'clip_changed'
1948 to bitfield. Remove unused #ifndef old.
1949 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1950 (GET_OVERLAYS_AT): Fix indentation.
1951 (for_each_per_buffer_object_at): New macro.
1952 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1953 (Fbuffer_local_variables): Use it.
1954 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1955 * alloc.c (allocate_buffer): Adjust to match new layout of
1956 struct buffer. Fix comment.
1957 (mark_overlay): New function.
1958 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1959 Lisp area of struct buffer.
1960 (mark_object): Use it. Adjust marking of misc objects
1961 and related comments.
1963 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1965 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1966 wrapper that is not needed because the wrapped code is a no-op (zero
1967 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1968 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1970 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1972 * alloc.c (mark_buffer): Simplify. Remove prototype.
1973 (mark_object): Add comment. Reorganize marking of vector-like
1974 objects. Use CHECK_LIVE for all vector-like objects except buffers
1975 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1976 redundant calls to mark_vectorlike for bool vectors.
1978 2012-06-30 Glenn Morris <rgm@gnu.org>
1980 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1982 * epaths.in (PATH_SITELOADSEARCH): New.
1983 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1984 This is rather than relying on --enable-locallisppath elements
1985 having "site-lisp" in their names. (Bug#10208#25, 11658)
1987 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1989 * w32proc.c (sys_select): Accept and ignore one more argument.
1991 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1993 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1994 (pselect) [!MS_DOS]: Redirect to sys_select.
1996 * sysdep.c: Don't include dos.h and dosfns.h.
1998 * process.c (sys_select):
1999 * msdos.c (sys_select): Accept one more argument and ignore it.
2001 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2002 adapt data types and code to that.
2005 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2006 which clashes with the gnulib function of the same name.
2008 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2010 * font.c (font_style_to_value, font_style_symbolic)
2011 (font_prop_validate_style): Add type checks for values in
2014 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2016 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2019 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2021 * xdisp.c (try_window_id): Undo last change.
2023 * w32.c (getwd): Adjust commentary about startup_dir.
2024 (init_environment): Always call sys_access, even in non-MSVC
2025 builds. Don't chdir to the directory of the Emacs executable.
2026 This undoes code from 1997 which was justified by the need to
2027 "avoid conflicts when removing and renaming directories". But its
2028 downside was that every relative file name was being interpreted
2029 relative to the directory of the Emacs executable, which can never
2030 be TRT. In particular, it broke sys_access when called with
2031 relative file names.
2032 (sys_access): Map GetLastError to errno.
2034 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2036 * window.h (struct window): Change type of 'fringes_outside_margins'
2037 to bitfield. Fix comment. Adjust users accordingly.

2040 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2043 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2045 * gnutls.c (emacs_gnutls_handshake):
2046 Add QUIT to make the loop interruptible.
2048 2012-06-29 Glenn Morris <rgm@gnu.org>
2050 * charset.c (init_charset): Make lack of etc/charsets fatal.
2052 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2054 * editfns.c (region_limit): Fix type mismatch.
2056 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2058 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2059 undefined. Convert from xassert to eassert.
2060 * nsmenu.m: Convert from xassert to eassert.
2061 * nsterm.m: Likewise.
2063 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

2067 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2069 Avoid integer overflow on scroll-left and scroll-right.
2070 * window.c (HSCROLL_MAX): New macro.
2071 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2072 overflow when requested scroll falls outside ptrdiff_t range.
2074 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2076 * window.h (struct window): Change type of 'hscroll',
2077 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2078 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2079 Adjust users accordingly.
2080 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2081 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2082 from EMACS_INT to ptrdiff_t.
2083 (make_window): Omit redundant initialization.
2085 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2089 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2091 * window.h (struct window): Change type of 'use_time' and
2092 'sequence_number' from Lisp_Object to int.

2102 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2103 adjust comments accordingly.

2154 avoid GCC warning about unused macro.
2156 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2158 * alloc.c (allocate_string): Omit intervals initialization.
2159 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2160 as in make_pure_string and make_pure_c_string.
2162 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2164 * alloc.c (allocate_string): Fix last change.
2166 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2216 * alloc.c: Remove build_string.
2217 * lisp.h: Define build_string as static inline. This provides
2218 a better opportunity to optimize away calls to strlen when the
2219 function is called with compile-time constant argument.
2220 * image.c (imagemagick_error): Convert to build_string.
2221 * w32proc.c (sys_spawnve): Likewise.
2222 * xterm.c (x_term_init): Likewise.
2224 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2226 Use sprintf return value instead of invoking strlen on result.
2227 In the old days this wasn't portable, since some sprintf
2228 implementations returned char *. But they died out years ago and
2229 Emacs already assumes sprintf returns int.
2230 Similarly for float_to_string.
2231 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2232 * ccl.c (ccl_driver):
2233 * character.c (string_escape_byte8):

2236 * print.c (print_object):
2237 * xdisp.c (message_dolog):
2238 * xfns.c (syms_of_xfns):
2239 Use sprintf or float_to_string result to avoid need to call strlen.
2240 * data.c (Fnumber_to_string):
2241 Use make_unibyte_string, since the string must be ASCII.
2242 * lisp.h, print.c (float_to_string): Now returns int length.
2243 * term.c (produce_glyphless_glyph):
2244 Use sprintf result rather than recomputing it.
2246 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2247 * Makefile.in (ALL_CFLAGS):
2248 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2254 strcasecmp if available.

2279 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2282 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2284 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2285 instead of truncating it to 63 (admittedly a generous limit).
2287 * process.c: Fix spelling and caps in comments.
2289 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2291 * emacs.c (setpgrp): Remove definition, unused.

2344 * dispnew.c (Fsleep_for, sit_for):
2345 * keyboard.c (kbd_buffer_get_event):

2349 when time_t is unsigned and as wide as intmax_t.
2350 See <http://bugs.gnu.org/9000#51>.
2352 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2381 language ID in the event parameters.
2383 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2413 Don't assume EMACS_TIME and struct timeval are the same type.
2415 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2417 Support higher-resolution time stamps (Bug#9000).
2418 The time stamps are only nanosecond-resolution at the C level,
2419 since that's the best that any real-world system supports now.
2420 But they are picosecond-resolution at the Lisp level, as that's
2421 easy, and leaves room for future OS improvements.
2423 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2426 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2427 Don't get current time unless it's needed.
2429 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2430 now provides it if it's absent.
2431 (start_atimer): Port to higher-res time stamps.
2432 Check for time stamp overflow. Don't get current time more
2433 often than is needed.
2435 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2436 Include systime.h, not time.h.
2437 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2439 * dired.c: Include stat-time.h.
2440 (Ffile-attributes): File times now have higher resolution.

2443 (struct image): Timestamp now has higher resolution.
2445 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2446 has at least microseconds now. All uses removed.
2447 (update_frame, update_single_window, update_window, update_frame_1)
2448 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2450 * editfns.c (time_overflow): Now extern.
2451 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2456 (decode_time_components, lisp_seconds_argument): New functions.
2457 (make_time): Now static.
2458 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2459 Report an error if the time is invalid, rather than having the caller
2462 * fileio.c: Include <stat-time.h>
2463 (Fcopy_file): Copy higher-resolution time stamps.
2464 Prefer to set the time stamp via a file descriptor if that works.
2465 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2466 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2467 (Fvisited_file_modtime, Fset_visited_file_modtime):
2468 Support higher-resolution time stamps.
2470 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2472 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2474 * image.c (prepare_image_for_display, clear_image_cache)
2475 (lookup_image): Port to higer-resolution time stamps.
2477 * keyboard.c (start_polling, bind_polling_period):
2478 Check for time stamp overflow.
2479 (read_char, kbd_buffer_get_event, timer_start_idle)
2480 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2481 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2482 Port to higher-resolution time stamps. Do not assume time_t is signed.
2483 (decode_timer): New function. Timers are now vectors of length 9,
2484 not 8, to accommodate the picosecond component.
2485 (timer_check_2): Use it.
2487 * nsterm.m (select_timeout, timeval_subtract): Remove.
2488 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2489 as they're a bit more accurate and handle overflow better.
2490 (ns_select): Change prototype to be compatible with pselect.
2491 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2492 * nsterm.h (ns_select): Adjust prototype.
2494 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2495 us-resolution time stamps.
2496 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2498 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2500 * lisp.h (time_overflow): New decl.
2501 (wait_reading_process_output): First arg is now intmax_t, not int,
2502 to accommodate larger waits.
2504 * process.h (struct Lisp_Process.read_output_delay):
2505 Now counts nanoseconds, not microseconds.
2506 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2508 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2509 (wait_reading_process_output):
2510 Port to ns-resolution time stamps.
2511 (Faccept_process_output, wait_reading_process_output):
2512 Check for time stamp overflow. Do not assume time_t is signed.
2513 (select_wrapper): Remove; we now use pselect.
2514 (Fprocess_attributes): Now generates ns-resolution time stamps.
2516 * sysdep.c: Include utimens.h. Don't include utime.h
2517 or worry about struct utimbuf; gnulib does that for us now.
2518 (gettimeofday): Remove; gnulib provides a substitute.
2519 (make_timeval): New function.
2520 (set_file_times): Now sets ns-resolution time stamps.
2521 New arg FD; all uses changed.
2522 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2523 (system_process_attributes):
2524 Now returns ns-resolution time stamp. All uses changed.
2525 Check for time stamp overflow.
2527 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2528 provides a substitute now.
2530 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2531 since it guarantees struct timespec.
2532 (EMACS_TIME): Now struct timespec, so that we can support
2533 ns-resolution time stamps.
2534 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2535 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2536 (EMACS_USECS): Remove.
2537 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2538 so multiply the arg by 1000 before storing it.
2539 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2541 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2542 Port to ns-resolution time stamps.
2543 (EMACS_TIME_NEG_P): Remove; replaced by....
2544 (EMACS_TIME_SIGN): New macro.

2546 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2547 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2548 (make_timeval, make_lisp_time, decode_time_components): New decls.
2549 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2550 that it mishandled time_t overflow. You can't compare by subtracting!
2551 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2552 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2554 * term.c: Include <sys/time.h>.
2555 (timeval_to_Time): New function, for proper overflow wraparound.

2563 (w32_get_internal_run_time):
2564 Port to higher-resolution Emacs time stamps.
2565 (ltime): Now accepts single 64-bit integer, as that's more convenient
2568 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2570 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2571 for compatibility with pselect. Support ns-resolution time stamps.
2573 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2575 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2576 Check for time stamp overflow, and support ns-resolution time stamps.
2578 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2579 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2580 (timeval_subtract): Remove; no longer needed.
2581 (XTflash, XTring_bell, x_wait_for_event):
2582 Port to ns-resolution time stamps. Don't assume time_t is signed.
2584 2012-06-22 Chong Yidong <cyd@gnu.org>

2588 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2590 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2591 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2592 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2593 staticidx goes up to 1597 out of 1600 = 0x640.)
2595 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2597 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2598 Otherwise, the umask might be mistakenly 0 while handling input signals.

2631 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2632 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2633 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2634 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2635 (METER_1, METER_2): Simplify.
2637 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

2641 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2643 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2644 gets killed during executing of this function (Bug#11665).
2645 Try to always return Qt when the buffer has been actually killed.
2646 (Vkill_buffer_query_functions): In doc-string say that functions
2647 run by this hook should not change the current buffer.
2649 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2651 Fix recently-introduced process.c problems found by static checking.

2669 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2671 * lisp.h (eassert): Assume C89 or later.
2672 This removes the need for CHECK.
2673 (CHECK): Remove. Its comments about always evaluating its
2674 argument were confusing, as 'eassert' typically does not evaluate
2677 * coding.c (produce_chars): Use ptrdiff_t, not int.
2679 * xterm.c (x_draw_underwave): Check for integer overflow.
2680 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2774 If all the glyphs of the glyph row came from strings, and we have no
2775 cursor positioning clues, put the cursor on the first glyph of the

2821 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
2823 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
2826 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
2828 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

2832 * frame.c (delete_frame): Remove outdated comment.
2833 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
2834 USE_LISP_UNION_TYPE.

2853 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2854 * alloc.c (make_number) [!defined make_number]:

2858 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
2859 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
2860 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
2861 -DUSE_LSB_TAG=0, to override the automatically-selected default.
2862 USE_LSB_TAG now is always defined to be either 0 or 1.
2864 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2865 code works fine either way, and efficiency is not a concern here,
2866 as the union type is for debugging, not for production.
2867 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2868 Use an inline function on all platforms when using the union type,
2869 since this is simpler and 'static inline' can be used portably
2871 (LISP_INITIALLY_ZERO): New macro.
2872 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2873 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

2942 dbus_type_is_basic if available.
2943 (xd_extract_signed, xd_extract_unsigned): Rename from
2944 extract_signed and extract_unsigned, respectively. Adapt callers.
2946 2012-06-09 Chong Yidong <cyd@gnu.org>

2955 * xdisp.c (vmessage): Treat frame message as multibyte.
2956 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2957 would generate the diagnostic "Making \302\247 buffer-local while
2960 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2962 * dispnew.c (showing_window_margins_p): Undo last change, which

2976 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2978 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2980 * alloc.c (allocate_vectorlike): Fix last change.
2982 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2984 Block-based vector allocation of small vectors.
2985 * lisp.h (struct vectorlike_header): New field `nbytes',
2986 adjust comment accordingly.

3011 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3013 * doprnt.c (doprnt): Truncate multibyte char correctly.
3014 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3015 would mishandle a string argument "Xc" if X was a multibyte
3016 character of length 2: it would truncate after X's first byte
3017 rather than including all of X.
3019 2012-06-06 Chong Yidong <cyd@gnu.org>
3021 * buffer.c (word_wrap): Doc fix.

3070 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3071 Convert pctcpu and pctmem to Lisp float properly.
3072 Let the compiler fold better, as 100.0/0x8000 is exact.
3074 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3076 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3079 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3081 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3083 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3085 For a 'struct window', replace some Lisp_Object fields to
3086 bitfields where appropriate, remove unused fields.
3087 * window.h (struct window): Remove unused 'last_mark_x' and
3088 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3089 change it's type from Lisp_Object to bitfield.
3090 Change type of 'force_start', 'optional_new_start',
3091 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3092 fields from Lisp_Object to bitfield. Adjust users accordingly.
3094 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3096 Pacify gcc -Wdouble-precision when using Xaw.
3097 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3098 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3099 Use 'float' consistently, rather than 'float' in most places
3100 and 'double' in a couple of places.
3102 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3104 * xdisp.c (handle_stop): Detect whether we have overlay strings
3105 loaded by testing it->current.overlay_string_index to be
3106 non-negative, instead of checking whether n_overlay_strings is
3107 positive. (Bug#11587)
3109 2012-05-31 Chong Yidong <cyd@gnu.org>
3111 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3113 * doc.c (Fsubstitute_command_keys): Doc fix.
3115 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3117 * search.c (search_buffer): Remove calls to
3118 r_alloc_inhibit_buffer_relocation, as it is now called by
3119 maybe_unify_char, which was the cause of relocation of buffer text
3122 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3124 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3125 for the duration of call to load_charset, to avoid problems with
3126 callers of maybe_unify_char that access buffer text through C
3129 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3130 decrement the inhibition flag, instead of just setting or
3133 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3135 Remove obsolete '#define static' cruft.
3136 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3137 This #undef was "temporary" in 2000; it is no longer needed
3138 now that '#define static' has gone away.
3139 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3140 (gray_bitmap_bits): Remove; no longer needed.
3141 All uses replaced with definiens.
3142 * xterm.c: Include "bitmaps/gray.xbm".
3144 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3146 Clean up __executable_start, monstartup when --enable-profiling.
3147 The following changes affect the code only when profiling.
3148 * dispnew.c (__executable_start): Rename from safe_bcopy.
3149 Define only on platforms that need it.
3150 * emacs.c: Include <sys/gmon.h> when profiling.
3151 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3152 (__executable_start): Remove decl, since lisp.h does it now.
3153 (safe_bcopy): Remove decl; no longer has that name.
3154 (main): Coalesce #if into single bit of code, for simplicity.
3155 Cast pointers to uintptr_t, since standard libraries want integers

3184 Do not create empty overlays with the evaporate property (Bug#9642).
3185 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3186 Bug#9642, but explicitly check that the buffer the overlay would
3187 be moved to is live and rearrange lines to make sure that errors
3188 will not put the overlay in an inconsistent state.
3189 (Fdelete_overlay): Cosmetics.
3191 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3193 * w32term.c (my_bring_window_to_top): New function.
3194 (x_raise_frame): Use handle returned by DeferWindowPos, which

3205 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3207 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3208 This avoids undefined behavior that might cause the eassert
3209 to not catch an out-of-range value.
3211 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3213 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3223 when referring to sectname field in printf format.
3225 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3227 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3228 Only r_alloc_inhibit_buffer_relocation needed to be added;
3229 the others were already declared.
3231 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3232 before checking whether it's out of range. Put the check inside
3234 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3236 2012-05-27 Ken Brown <kbrown@cornell.edu>
3238 * callproc.c (Fcall_process): Restore a line that was accidentally
3239 commented out in the 2011-02-13 change (bug#11547).

3243 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3244 defined on ralloc.c.
3246 * buffer.c [REL_ALLOC]: Remove prototypes of
3247 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3248 they are now on lisp.h.
3250 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3252 * search.c (search_buffer): Use it to inhibit relocation of buffer
3253 text while re_search_2 is doing its job, because re_search_2 is
3254 passed C pointers to buffer text. (Bug#11519)
3256 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3259 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3260 state after an additional call to move_it_in_display_line_to, keep
3261 the values of it->max_ascent and it->max_descent found for the
3263 (pos_visible_p): Revert the comparison against bottom_y to what it
3264 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3267 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3269 Fix coding-related core dumps with gcc -ftrapv.
3270 The code was computing A - B, where A and B are pointers, and B is
3271 random garbage. This can lead to core dumps on platforms that
3272 have special pointer registers, and it also leads to core dumps on
3273 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3274 A - B only when B is initialized properly.
3275 * coding.c (coding_set_source, coding_set_destination): Return void.
3276 (coding_change_source, coding_change_destinations): New functions,
3277 with the old behaviors of coding_set_source and coding_set_destination.
3278 All callers that need an offset changed to use these new functions.
3280 2012-05-26 Glenn Morris <rgm@gnu.org>

3298 gen_help_event to produce help-echo message in the echo area.
3299 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3302 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3304 * lread.c (read1): Simplify slightly to avoid an overflow warning
3305 with GCC 4.7.0 on x86-64.
3307 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3309 * bidi.c (bidi_mirror_char): Revert last change: an int is
3310 definitely wide enough here.
3312 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3314 Fix integer width and related bugs (Bug#9874).

3326 Use int, not EMACS_INT, where int is wide enough.

3346 (Foverlay_recenter, last_overlay_modification_hooks_used)
3347 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3348 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3349 (validate_region): Omit unnecessary test for b <= e,
3350 since that's guaranteed by the previous test.
3351 (adjust_overlays_for_delete): Avoid pos + length overflow.
3352 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3353 (report_overlay_modification):
3354 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3355 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3364 not int, to avoid needless 32-bit limit on 64-bit hosts.
3365 (exec_byte_code): Use tighter memory-full test, one that checks
3366 for alloca overflow. Don't compute the address of the object just
3367 before an array, as that's not portable. Use EMACS_INT, not
3368 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3369 * callint.c (Fcall_interactively):
3370 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3382 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3383 (casify_object): Avoid integer overflow when overallocating buffer.
3384 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3387 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3388 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3389 integers are now checked earlier. All uses replaced with XINT.
3391 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3392 For CCL_MapSingle, check that content and value are in int range.
3393 (ccl_driver, Fregister_code_conversion_map):
3394 Check that Vcode_version_map_vector is a vector.
3395 (resolve_symbol_ccl_program): Check that vector header is in range.
3396 Always copy the vector, so that we can check its contents reliably
3397 now rather than having to recheck each instruction as it's being
3398 executed. Check that vector words fit in 'int'.
3399 (ccl_get_compiled_code, Fregister_ccl_program)
3400 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3401 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3402 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3403 contents are in range.
3404 (Fccl_execute_on_string): Check that status is in range.
3405 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3406 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3407 Accept and return EMACS_INT, not int, because callers can pass values

3413 (string_escape_byte8, Fget_byte):
3414 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3415 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3416 avoid mishandling large integers.
3417 * character.h: Adjust decls to match defn changes elsewhere.

3427 Don't rely on undefined behavior with signed left shift overflow.
3428 Don't assume unsigned int fits into fixnum, or that fixnum fits
3429 into unsigned int. Don't require max_code to be a valid fixnum;
3430 that's not true for gb10830 4-byte on a 32-bit host. Allow
3431 invalid_code to be a cons, for the same reason. Require code_offset
3432 to be a character. Avoid int overflow if max_char is close
3434 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3435 this is intended anyway and avoids some undefined behavior.
3436 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3437 INDEX_TO_CODE_POINT, as that's what it expects.
3438 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3439 * charset.h (DECODE_CHAR): Return int, not unsigned;
3440 this is what was intended anyway, and it avoids undefined behavior.
3441 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3442 integer-overflow issues.
3443 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3444 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3445 where the argument is EMACS_INT, and this behavior is not intended.
3446 * chartab.c (Fmake_char_table, Fset_char_table_range)
3447 (uniprop_get_decoder, uniprop_get_encoder):
3448 Don't assume fixnum fits in int.
3449 * cmds.c (move_point): New function, that does the gist of
3450 Fforward_char and Fbackward_char, but does so while checking
3451 for integer overflow more accurately.
3452 (Fforward_char, Fbackward_char): Use it.
3453 (Fforward_line, Fend_of_line, internal_self_insert)
3454 (internal_self_insert):
3455 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3457 target_clm and actual_clm.

4236 2012-05-14 Glenn Morris <rgm@gnu.org>
4238 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4239 Put "libexec" before "bin", for the sake of init_callproc_1.
4241 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4243 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

4246 (report_error, report_error_1, make_hdr, copy_sym)
4247 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4248 Make arguments const char *, not char *, to avoid violations of C
4249 standard and to fix some AIX warnings reported by Gilles Pion.
4251 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4253 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4254 already have overlays loaded.
4255 (handle_single_display_spec): Before returning without displaying
4256 fringe bitmap, synchronize the bidi iterator with the main display
4257 iterator, by calling iterate_out_of_display_property.
4258 (iterate_out_of_display_property): Detect buffer iteration by
4259 testing that it->string is a Lisp string.
4260 (get_next_display_element): When the current object is exhausted,
4261 and there's something on it->stack, call set_iterator_to_next to
4262 proceed with what's on the stack, instead of returning zero.
4263 (set_iterator_to_next): If called at the end of a Lisp string,
4264 proceed to consider_string_end without incrementing string
4265 position. Don't increment display vector index past the end of
4266 the display vector. (Bug#11417)
4267 (pos_visible_p): Don't report a position visible when move_it_to
4268 stopped at the last line of window, which happens to be scanned
4269 backwards by the bidi iteration. (Bug#11464)
4271 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4273 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4274 and right-margin display specs even if the spec is invalid or we
4275 are on a TTY, and thus unable to display on the fringes.
4276 That's because the text with the property will not be displayed anyway,
4277 so we need to signal to the caller that this is a "replacing"
4278 display spec. This fixes display when the spec is invalid or we
4281 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4283 * unexaix.c (make_hdr): Fix typo in prototype.
4284 This bug broke the build on AIX. Problem reported by Gilles Pion.
4286 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4288 * keyboard.c (kbd_buffer_get_event): Read special events also in
4289 batch mode. (Bug#11415)
4291 2012-05-12 Glenn Morris <rgm@gnu.org>

4299 2012-05-12 Glenn Morris <rgm@gnu.org>
4301 * Makefile.in (MKDIR_P): New, set by configure.
4302 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4304 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

4314 Update dependencies.
4316 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4318 * xgselect.c (xg_select): Put maxfds+1 into a var.
4319 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4321 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4323 2012-05-10 Dave Abrahams <dave@boostpro.com>
4325 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4326 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4328 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4330 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4331 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4332 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4333 Initialize xd_registered_buses.
4335 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4337 Untag more efficiently if USE_LSB_TAG.
4338 This is based on a proposal by YAMAMOTO Mitsuharu in
4339 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4340 For an admittedly artificial (nth 8000 longlist) benchmark on
4341 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4342 Emacs's overall text size by 1%.
4343 * lisp.h (XUNTAG): New macro.
4344 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4345 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4346 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4347 * eval.c (Fautoload):
4348 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4349 * frame.h (XFRAME): Use XUNTAG.
4351 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4352 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4353 Remove unportable assumptions about print widths of types like
4355 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4356 intptr_t when converting between pointer and integer, to avoid GCC
4357 warnings about wrong width.
4359 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4361 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4362 stack for each reader_thread, instead of defaulting to 8MB
4363 determined by the linker. This avoids failures in creating
4364 subprocesses on Windows 7, see the discussion in this thread:
4365 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4367 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4369 Fix up display of the *Minibuf-0* buffer in the mini window.
4370 * keyboard.c (read_char): Don't clear the echo area if there's no
4372 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4373 contents of *Minibuf-0*) if there's no message displayed in its stead.
4375 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4377 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4380 2012-05-06 Chong Yidong <cyd@gnu.org>
4382 * lisp.mk (lisp): Update.
4384 2012-05-05 Jim Meyering <meyering@redhat.com>
4386 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4388 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4390 * data.c (PUT_ERROR): New macro.
4391 (syms_of_data): Use it. Add new error type `user-error'.
4392 * undo.c (user_error): New function.
4393 (Fprimitive_undo): Use it.
4394 * print.c (print_error_message): Adjust print style for `user-error'.
4395 * keyboard.c (user_error): New function.
4396 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4398 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4400 Do not limit current-time-string to years 1000..9999.
4401 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4402 (Fcurrent_time_string): Support any year that is supported by the
4403 underlying localtime representation. Don't use asctime, as it
4404 has undefined behavior for years outside the range -999..9999.
4406 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4408 Fix race conditions involving setenv, gmtime, localtime, asctime.
4409 Without this fix, interrupts could mess up code that uses these
4410 nonreentrant functions, since setting TZ invalidates existing
4411 tm_zone or tzname values, and since most of these functions return
4412 pointers to static storage.
4413 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4414 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4415 Grow the critical sections to include not just invoking
4416 localtime/gmtime, but also accessing these functions' results
4417 including their tm_zone values if any, and any related TZ setting.
4418 (format_time_string): Last arg is now struct tm *, not struct tm **,
4419 so that the struct tm is saved in the critical section.
4420 All callers changed. Simplify allocation of initial buffer, partly
4421 motivated by the fact that memory allocation needs to be outside
4422 the critical section.
4424 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4426 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4427 with RESET_INTERVAL.
4429 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4430 Remove duplicated buffer name initialization.
4432 2012-05-02 Jim Meyering <jim@meyering.net>
4434 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4436 * xfns.c (x_window): Use xstrdup (Bug#11375).
4438 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4440 * xdisp.c (pos_visible_p): If already at a newline from the
4441 display string before the 'while' loop, don't walk back the glyphs
4442 from it3.glyph_row. Solves assertion violation when the display
4443 string begins with a newline (egg.el). (Bug#11367)
4445 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4447 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4450 2012-05-01 Glenn Morris <rgm@gnu.org>
4452 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4453 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4454 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4455 All were removed before 23.1.
4457 * dispnew.c: Remove HAVE_LIBNCURSES test;
4458 it is always true on relevant platforms.
4460 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4461 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4463 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4465 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4467 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4468 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4471 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4473 Do not avoid creating empty evaporating overlays (Bug#9642).
4474 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4475 That is, do not delete an evaporating overlay if it becomes
4476 empty after its bounds are adjusted to fit within its buffer.
4477 This fix caused other problems, and I'm reverting it until we get
4478 to the bottom of them.
4480 2012-04-27 Chong Yidong <cyd@gnu.org>
4482 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4484 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4486 * xdisp.c (pos_visible_p): If the window start position is beyond
4487 ZV, start the display from buffer beginning. Prevents assertion
4488 violation in init_iterator when the minibuffer window is scrolled
4491 * window.c (window_scroll_pixel_based): Likewise.
4493 2012-04-27 Chong Yidong <cyd@gnu.org>
4495 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4497 2012-04-27 Glenn Morris <rgm@gnu.org>
4499 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4500 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4502 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4504 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4505 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4507 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4509 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4510 display element, check also the underlying string or buffer
4511 character. (Bug#11341)
4513 * w32menu.c: Include w32heap.h.
4514 (add_menu_item): If the call to AppendMenuW (via
4515 unicode_append_menu) fails, disable Unicode menus only if we are
4516 running on Windows 9X/Me.
4518 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4520 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4523 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4525 * keyboard.c (read_char): Don't wipe echo area for select window
4526 events: These might get delayed via `mouse-autoselect-window'
4529 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4531 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4532 manipulation of :loaded-from data.
4534 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4536 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4537 now a cons (bug#11311).
4539 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4541 Do not create empty overlays with the evaporate property (Bug#9642).
4542 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4543 if it becomes empty after its bounds are adjusted to fit within
4544 its buffer. Without this fix, in a nonempty buffer (let ((o
4545 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4546 yields an empty overlay that has the evaporate property, which is
4547 not supposed to happen.
4549 Fix minor GTK3 problems found by static checking.
4550 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4551 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4552 (struct _EmacsFixedClass, emacs_fixed_get_type):

4565 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4567 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4569 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4570 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4571 (__malloc_size_t, __malloc_ptrdiff_t):
4572 Remove. All uses removed, replaced by the definiens if needed,
4573 since we can assume C89 or better now.
4574 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

4584 Define using prototypes, not old style.
4585 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4586 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

4664 * sysdep.c [__FreeBSD__]: Minor cleanups.
4665 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4666 Use Emacs indenting style more consistently. Avoid some casts.
4667 Use 'double' consistently rather than mixing 'float' and 'double'.
4669 2012-04-21 Eduard Wiebe <usenet@pusto.de>
4671 * sysdep.c (list_system_processes, system_process_attributes):

4687 (print_object): Check for cycles even when print-circle is nil and
4688 print-gensym is t, but only check print_depth if print-circle is nil.
4690 2012-04-20 Chong Yidong <cyd@gnu.org>
4692 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4693 set the status to "failed" and ensure that sentinel is run.

4748 New extern decls, to avoid calling undeclared functions.
4749 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4750 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4751 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

4753 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4754 Remove one incorrect comment and fix another.

4768 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4769 Remove decls. This fixes an "It stinks!".
4771 * alloc.c (which_symbols): Fix alignment issue / type clash.

4796 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4798 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4800 * lread.c (lisp_file_lexically_bound_p):

4821 2012-04-11 Daniel Colascione <dancol@dancol.org>
4823 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4824 against is gone. It's better to use vfork now so that when Cygwin
4825 gains a new, working vfork, we use it automatically (bug#10398).
4827 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4856 Pass EMACS rather than BUILT_EMACS.
4858 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4860 * process.c (make_process):
4861 * process.h: Add integer `gnutls_handshakes_tried' member to
4864 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4865 Add convenience `GNUTLS_LOG2i' macro.
4867 * gnutls.c (gnutls_log_function2i): Convenience log function.
4868 (emacs_gnutls_read): Use new log functions,
4869 `gnutls_handshakes_tried' process member, and
4870 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4871 attempts per process (connection).
4873 2012-04-09 Chong Yidong <cyd@gnu.org>
4875 * eval.c (Fuser_variable_p, user_variable_p_eh)

4880 * minibuf.c (Fread_variable): Callers changed.
4882 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4884 * xdisp.c (set_cursor_from_row): If the display string appears in
4885 the buffer at position that is closer to point than the position
4886 after the display string, display the cursor on the first glyph of
4887 the display string. Fixes cursor display when a 'display' text
4888 property immediately follows invisible text. (Bug#11094)
4890 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4892 composite.c: use 'double' consistently
4893 * composite.c (get_composition_id): Use 'double' consistently
4894 instead of converting 'float' to 'double' and vice versa; this is
4895 easier to understand and avoids a GCC warning.
4897 2012-04-09 Glenn Morris <rgm@gnu.org>
4899 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4900 preparation for dumping it with emacs. (Bug#4789)
4901 (leimdir): New variable.
4902 ($(leimdir)/leim-list.el): New rule.

4921 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
4922 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4923 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4924 objects, as mark_maybe_pointer will catch them otherwise.
4925 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4926 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4928 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4930 Fix typo that broke non-Windows builds.
4931 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

4937 * makefile.w32-in (OBJ2): Add xml.$(O).
4938 (GLOBAL_SOURCES): Add xml.c.
4939 ($(BLD)/xml.$(O)): New dependency list.
4941 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
4942 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4943 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4944 [!WINDOWSNT]: New macros.
4945 (init_libxml2_functions, libxml2_loaded_p): New functions.
4946 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4947 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4948 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4949 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4951 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4952 Call init_libxml2_functions before calling libxml2 functions.
4953 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4955 * emacs.c: Don't include libxml/parser.h.
4956 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4957 xmlCleanupParser directly.
4959 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4961 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4963 * indent.c (Fvertical_motion): If there is a display string at
4964 point, use it.vpos to compute how many lines to backtrack after
4965 move_it_to point. (Bug#11133)
4967 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4969 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4970 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4971 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4972 macros related to unification of CJK characters. For the details,
4973 see the discussion following the message here:
4974 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4976 2012-04-04 Chong Yidong <cyd@gnu.org>
4978 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4980 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4982 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4983 instead of alloca. (Bug#11138)
4985 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4987 * w32menu.c (is_simple_dialog): Properly check lisp types.
4990 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4992 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4993 position we get to after a call to move_it_to fails the
4994 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4995 only if we wind up in a string from display property. (Bug#11063)
4997 * window.c (Fdelete_other_windows_internal): Invalidate the row
4998 and column information about mouse highlight, so that redisplay
4999 restores it after reallocating the glyph matrices. (Bug#7464)
5001 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5002 string comes from a `display' text property, use the buffer
5003 position of that property as if we actually saw that position in
5005 (move_it_by_lines): Remove the assertion that
5006 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5007 violated when there's a before-string at the beginning of a line.
5010 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5012 * xdisp.c (append_space_for_newline): If the default face was
5013 remapped, use the remapped face for the appended newline.
5014 (extend_face_to_end_of_line): Use the remapped default face for
5015 extending the face to the end of the line.
5016 (display_line): Call extend_face_to_end_of_line when the default
5017 face was remapped. (Bug#11068)
5019 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5021 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5023 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5025 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5027 2012-03-27 Glenn Morris <rgm@gnu.org>
5029 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5032 2012-03-26 Kenichi Handa <handa@m17n.org>
5034 * dispextern.h (struct glyph): Fix previous change. Change the
5035 bit length of glyphless.ch to 25 (Bug#11082).
5037 2012-03-26 Chong Yidong <cyd@gnu.org>
5039 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5040 (command_loop_1): Use it; inhibit selection update for
5041 handle-select-window too (Bug#8996).
5043 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5045 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5047 2012-03-25 Kenichi Handa <handa@m17n.org>
5049 * dispextern.h (struct glyph): Change the bit length of
5050 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5052 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5054 * s/ms-w32.h (tzname): Include time.h before redirecting to
5055 _tzname. Fixes the MSVC build. (Bug#9960)
5057 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5059 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5062 * xterm.c (XTread_socket): Only modify handling_signal if
5063 !SYNC_INPUT. (Bug#11080)
5065 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5067 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5068 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5069 when fetching a multibyte character consumes more bytes than
5070 CHAR_BYTES returns, due to unification of CJK characters in
5071 string_char. (Bug#11073)
5073 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5075 * process.c (wait_reading_process_output): Handle pty disconnect
5076 by refraining from sending oneself a SIGCHLD (bug#10933).
5078 2012-03-22 Chong Yidong <cyd@gnu.org>
5080 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5082 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

5084 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5085 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5087 2012-03-21 Chong Yidong <cyd@gnu.org>
5089 * xfaces.c (Vface_remapping_alist): Doc fix.
5091 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5093 * w32proc.c (Fw32_set_console_codepage)
5094 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5097 2012-03-20 Chong Yidong <cyd@gnu.org>
5099 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5100 to reflect default non-nil value of redisplay-dont-pause.
5102 2012-03-19 Kenichi Handa <handa@m17n.org>
5104 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5105 it fit in a valid range (Bug#11003).
5107 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5109 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5110 that is not from display property, accept the row as a "cursor
5111 row" if one of the string's character has a non-nil `cursor'
5112 property. Fixes cursor positioning when there are newlines in
5113 overlay strings, e.g. in icomplete.el. (Bug#11035)
5115 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5117 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5119 2012-03-12 Chong Yidong <cyd@gnu.org>
5121 * eval.c (inhibit_lisp_code): Rename from
5122 inhibit_window_configuration_change_hook; move from window.c.
5124 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5125 * window.c (run_window_configuration_change_hook)
5126 (syms_of_window): Callers changed.

5141 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5143 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5145 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5146 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5149 2012-03-03 Glenn Morris <rgm@gnu.org>
5151 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5153 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5155 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5156 position past the first glyph_row that ends at ZV. (Bug#10902)
5157 (redisplay_window, next_element_from_string): Fix typos in
5159 (redisplay_window): Pass to move_it_vertically the margin in
5160 pixels, not in screen lines.
5162 2012-03-02 Glenn Morris <rgm@gnu.org>
5164 * buffer.c (buffer-list-update-hook): Doc fix.
5166 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5168 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5169 push_it before setting up the iterator for the first overlay
5170 string, even if we have an empty string loaded.
5171 (next_overlay_string): If there's an empty string on the iterator
5172 stack, pop the stack. (Bug#10903)
5174 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5176 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5177 Suggested by Stefan Monnier in
5178 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5179 * alloc.c (widen_to_Lisp_Object): New static function.
5180 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5181 and widening them to Lisp_Objects. This would work even if
5182 USE_LSB_TAG is defined and wide integers are used, which might
5183 happen in a future version of Emacs.
5185 2012-02-25 Chong Yidong <cyd@gnu.org>
5187 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5190 * xselect.c (Fx_selection_exists_p): Doc fix.
5191 (x_clipboard_manager_save_all): Print an informative message
5192 before saving to clipboard manager.
5194 2012-02-24 Chong Yidong <cyd@gnu.org>
5196 * keyboard.c (process_special_events): Handle all X selection
5197 requests in kbd_buffer, not just the next one (Bug#8869).

5202 call when setting menu-bar-lines and tool-bar-lines parameters.
5203 (unwind_create_frame_1): New helper function.
5205 * window.c (inhibit_window_configuration_change_hook): New var.
5206 (run_window_configuration_change_hook): Obey it.
5207 (syms_of_window): Initialize it.
5209 2012-02-22 Chong Yidong <cyd@gnu.org>

5224 when computing $valmask.
5226 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5227 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5228 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5229 It's useless in that case, and it can cause problems on hosts
5230 that allocate halves of EMACS_INT values separately.
5231 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5232 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5233 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5234 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5235 it avoids undefined behavior on hosts where shifting right by more
5236 than the word width has undefined behavior.
5238 2012-02-19 Chong Yidong <cyd@gnu.org>
5240 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5241 (Funhandled_file_name_directory, Ffile_name_as_directory)

5258 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5260 2012-02-15 Chong Yidong <cyd@gnu.org>
5262 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5263 marked as special. Also, starting docstrings with * is obsolete.

5278 2012-02-12 Chong Yidong <cyd@gnu.org>
5280 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5281 as that creates a dangerous corner case.
5283 * window.c (Fdelete_window_internal): Invalidate the mouse
5284 highlight (Bug#9904).
5286 2012-02-12 Glenn Morris <rgm@gnu.org>

5289 (Fx_get_selection_internal, Fx_disown_selection_internal)
5290 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5291 * nsselect.m (Fx_own_selection_internal)
5292 (Fx_disown_selection_internal, Fx_selection_exists_p)
5293 (Fx_selection_owner_p, Fx_get_selection_internal):
5294 Sync docs and argument specs with the xselect.c versions.
5296 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

5318 * buffer.c (Fbuffer_local_variables)
5319 (buffer_lisp_local_variables): Handle unbound vars correctly;
5320 don't let Qunbound leak into Lisp.
5322 2012-02-07 Glenn Morris <rgm@gnu.org>
5324 * image.c (Fimagemagick_types): Doc fix.
5326 * image.c (imagemagick-render-type): Change it from a lisp object

5863 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
5864 attributes are tested _before_ calling verify_row_hash, to protect
5865 against GCC re-ordering of the tests. (Bug#10164)
5867 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>
5869 * xterm.h (struct x_output): net_wm_state_hidden_seen is new.

5888 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
5889 of scroll runs so as to avoid assigning disabled bogus rows and
5890 unnecessary graphics copy operations.
5892 2011-11-27 Eli Zaretskii <eliz@gnu.org>
5894 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

5901 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
5902 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
5903 this macro definition.
5905 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
5908 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

5930 * xdisp.c (redisplay_window): If cursor row is not fully visible
5931 after recentering, and scroll-conservatively is set to a large
5932 number, scroll window by a few more lines to make the cursor fully
5933 visible and out of scroll-margin. (Bug#10105)
5934 (start_display): Don't move to the next line if the display should
5935 start at a newline that is part of a display vector or an overlay

6017 Problem reported by Andreas Schwab in
6018 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6019 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6020 is set, removing the need for VIRT_ADDRESS_VARIES.
6021 (PURE_P): Use a more-efficient implementation that needs just one
6022 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6023 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6024 to 4 (xorl, subq, cmpq, setbe).
6025 * alloc.c (pure): Always extern now, since that's the
6026 VIRT_ADDR_VARIES behavior.
6027 (PURE_POINTER_P): Use a single comparison, not two, for
6028 consistency with the new puresize.h.
6029 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6030 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6036 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6037 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6038 behave as if the cursor position were at the window margin.
6040 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6041 and the cursor position is out of bounds, behave as if the cursor
6042 position were at the window margin. (Bug#10075)
6044 2011-11-18 Chong Yidong <cyd@gnu.org>
6046 * window.c (Fwindow_combination_limit): Make first argument
6047 non-optional, since it is meaningless for live windows like the

6063 (copy_row_except_pointers): Preserve the used[] arrays and the
6064 hash values of the two rows. (Bug#10035)
6065 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6067 * xdisp.c (row_hash): New function, body extracted from
6068 compute_line_metrics.
6069 (compute_line_metrics): Call row_hash, instead of computing the
6072 * dispnew.c (verify_row_hash): Call row_hash for computing the
6073 hash code of a row, instead of duplicating code from xdisp.c.
6075 * dispextern.h (row_hash): Add prototype.
6077 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6079 * frame.c (delete_frame): Don't delete the terminal when the last

6102 (Fset_window_nest): Rename to Fset_window_combination_limit.
6103 (Vwindow_nest): Rename to Vwindow_combination_limit.
6104 (recombine_windows, make_parent_window, make_window)
6105 (Fsplit_window_internal, saved_window)
6106 (Fset_window_configuration, save_window_save): Rename all
6107 occurrences of window_nest to window_combination_limit.
6109 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6111 * image.c (imagemagick_load_image): Fix typo.
6113 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6115 * xdisp.c (display_line): Move the call to
6116 highlight_trailing_whitespace before the call to
6117 compute_line_metrics, since the latter needs to see the final
6118 faces of all the glyphs to compute ROW's hash value.
6119 Fixes assertion violations in row_equal_p. (Bug#10035)
6121 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6123 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6128 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6129 with user-defined heap size. Bump the default size of the temacs
6130 heap to 27MB, to avoid memory warning when running temacs.
6131 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6133 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
6134 current_matrix and desired_matrix. (Bug#9990)

6180 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6182 Avoid some portability problems by eschewing 'extern inline' functions.
6183 The trivial performance wins aren't worth the portability hassles; see
6184 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6186 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6187 (window_box_width, window_box_left, window_box_left_offset)
6188 (window_box_right, window_box_right_offset): Undo previous change,
6189 by removing the "extern"s.
6190 * intervals.c (adjust_intervals_for_insertion)
6191 (adjust_intervals_for_deletion): Undo previous change,
6192 making these static again.
6193 (offset_intervals, temp_set_point_both, temp_set_point)
6194 (copy_intervals_to_string): No longer inline.
6195 * xdisp.c (window_text_bottom_y, window_box_width)

6234 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6235 This is also needed for porting to any host where GC_MARK_STACK is
6236 not GC_MAKE_GCPROS_NOOPS.
6237 (which_symbols): Use it.

6252 * xmenu.c (cleanup_widget_value_tree): New function.
6253 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6260 (window_box_width, window_box_left, window_box_left_offset)
6261 (window_box_right, window_box_right_offset): Declare extern.
6262 Otherwise, these inline functions do not conform to C99 and
6263 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6264 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6265 * intervals.c (adjust_intervals_for_insertion)
6266 (adjust_intervals_for_deletion): Now extern, because otherwise the
6267 extern inline functions 'offset_intervals' couldn't refer to it.
6268 (static_offset_intervals): Remove.
6269 (offset_intervals): Rewrite using the old contents of
6270 static_offset_intervals. The old version didn't conform to C99
6271 because an extern inline function contained a reference to an
6272 identifier with static linkage.
6274 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6276 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6294 (Fwindow_vscroll): Doc fix.
6295 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6296 argument, since it makes no sense to pass a live window and for
6297 consistency with window-child.

6376 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6378 * xdisp.c (note_mouse_highlight): If either of
6379 previous/next-single-property-change returns nil, treat that as
6380 the beginning or the end of the buffer. (Bug#9955)
6382 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6384 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

6404 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6405 Don't stop backward scan on the continuation glyph, even though
6406 its CHARPOS is positive.
6407 (mouse_face_from_buffer_pos, note_mouse_highlight):
6408 Rename cover_string to disp_string.
6410 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6412 * window.c (temp_output_buffer_show): Don't use
6413 Vtemp_buffer_show_specifiers.
6414 (Vtemp_buffer_show_specifiers): Remove unused variable.
6416 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6418 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6419 past the beginning of the current glyph matrix.

6443 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6444 so that this new function doesn't get optimized away by a
6445 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6447 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6449 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6451 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6469 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6470 Not clear what it was for, and it causes various bugs. (Bug#9839)
6472 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6474 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6475 possible random value that matches one of those tested as
6476 condition to clear the mouse face.
6478 2011-10-28 Chong Yidong <cyd@gnu.org>
6480 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6494 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6496 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6497 <oslsachem@gmail.com> for helping to debug this.
6499 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6500 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6501 (g_b_init_get_glyph_outline_w): New static variables.
6502 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

6504 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6505 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6507 (w32font_open_internal, compute_metrics):
6508 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6509 instead of calling the "wide" APIs directly.
6511 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6513 * w32.h (syms_of_w32font): Add prototype.
6515 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6517 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6518 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6519 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6524 * process.c (make_process): Set gnutls_state to NULL.
6526 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6527 non-NULL, regardless of GNUTLS_INITSTAGE.
6528 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

6539 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6540 (deactivate_process): Call emacs_gnutls_deinit.

6549 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6551 * w32fns.c (w32_default_color_map): New function,
6552 extracted from Fw32_default_color_map.
6553 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6555 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6557 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6559 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6561 * keyboard.c (test_undefined): New function (bug#9751).
6562 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6564 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6566 * sysdep.c (init_sys_modes): Fix the check for the controlling
6567 terminal (Bug#6649).
6569 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6571 * dispextern.h (struct bidi_it): New member next_en_type.
6573 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6574 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6575 current character, check also for next_en_type being WEAK_EN.
6576 (bidi_resolve_weak): Don't enter the expensive loop if the current
6577 position is before next_en_pos. Record the bidi type of the first
6578 non-ET, non-BN character we find, in addition to its position.
6579 (bidi_level_of_next_char): Invalidate next_en_type when
6580 next_en_pos is over-stepped.
6582 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6584 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6585 * editfns.c: Rewrite current-time-zone so that it invokes
6586 the equivalent of (format-time-string "%Z") to get the time zone name.
6587 This fixes a bug when the time zone name contains characters that
6588 need converting from the system time locale to Emacs internal format.
6589 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6590 that patch fixed format-time-string to do the conversion, but
6591 I forgot to fix current-time-zone.
6592 (format_time_string): New function, containing most of
6593 what Fformat_time_string used to contain.
6594 (Fformat_time_string): Rewrite in terms of format_time_string.
6595 This doesn't change this function's behavior.
6596 (current-time-zone): Rewrite to use format_time_string.
6597 This fixes the bug reported by Michael Schierl in
6598 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6599 Jason Rumney's 2007-06-07 change worked around this bug, but
6601 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6603 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6605 * xdisp.c (start_display): If the character at POS is displayed
6606 via a display vector, reset IT->current.dpvec_index to zero.
6607 (try_window_reusing_current_matrix): If a line ends in a display
6608 vector or the next line starts in a display vector, continue
6609 redrawing the window even though the character position of
6610 start_row was reached.
6613 2011-10-18 Chong Yidong <cyd@gnu.org>
6615 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6616 with nobreak-char-display too.
6618 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6620 Fix part 3 of bug#9771.
6621 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6622 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6623 non-neutral characters if the current character is a paragraph
6624 separator (a.k.a. Newline). This avoids running the same
6625 expensive loop twice, once when we consume the preceding newline
6626 and the other time when the line actually needs to be displayed.
6627 Avoid the loop when we see neutrals on the base embedding level
6628 following a character whose directionality is the same as the
6629 paragraph's. This avoids running the expensive loop when a line
6630 ends in a long sequence of neutrals, like control characters.
6631 Add assertion against STRONG_AL type. Slightly rearrange code
6632 that determines the type of a neutral given the first non-neutral
6634 (bidi_level_of_next_char): Set next_en_pos to zero when
6635 invalidating its info.
6637 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6639 * xdisp.c (push_display_prop): Determine whether to record string
6640 or buffer position by IT->string, not by IT->method. Allow
6641 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6642 (move_it_vertically_backward): Don't look for character position
6643 immediately after the newline when in a continuation line.
6646 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6648 * window.c (coordinates_in_window): Rewrite and delabelize
6649 vertical border check. (Bug#5357) (Bug#9618)
6651 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6653 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6654 errors in XSetWindowBorder (bug#9310).
6656 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6658 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6659 avoid crash when xmalloc overrun checking is enabled.
6661 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6663 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6664 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6665 cursor motion with <left> and <right> arrow keys.
6667 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6668 some callers set that themselves.
6670 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6672 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6673 display string and the previous row comes from the same string and
6674 is empty. (Bug#9739) (Bug#9738)
6676 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6678 * doc.c (get_doc_string): Encode file name (bug#9735).
6680 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6682 * bidi.c (bidi_level_of_next_char):
6683 * xdisp.c (get_visually_first_element): Remove old incorrect
6684 comments regarding the Unicode Line Separator character.
6686 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6688 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6690 * alloc.c (Fgc_status): Do not access beyond zombies array
6691 boundary if nzombies > MAX_ZOMBIES.
6692 * alloc.c (dump_zombies): Add missing format specifier.
6694 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6696 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6697 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6699 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6700 Some packages use them to denote characters with modifiers.
6702 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6704 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6705 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6706 matching a pp-number. Rename parameter var to var1.
6708 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6710 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6712 2011-10-08 Glenn Morris <rgm@gnu.org>
6714 * callint.c (Fcall_interactively): Give a more explicit error for the
6715 'c' case with a non-character input. (Bug#8479)
6717 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6719 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6721 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6722 lines that are hscrolled on the left.
6724 * dispnew.c (buffer_posn_from_coords): Account for a possible
6725 presence of header-line. (Bug#4426)
6727 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6729 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6730 Don't advertise functionality which we discourage or doesn't work.
6732 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6734 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6735 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6736 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6737 this makes Emacs dump core during garbage collection on rare
6738 occasions. sizeof is obviously inferior to offsetof here, so
6739 stick with offsetof.
6740 (GC_POINTER_ALIGNMENT): New macro.
6741 (mark_memory): Omit 3rd (offset) arg; caller changed.
6742 Don't assume EMACS_INT alignment is the same as pointer alignment.
6744 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6746 * keyboard.c (read_key_sequence_remapped): New var.
6747 (read_key_sequence): Compute remapping in the right buffer.
6748 (command_loop_1): Use read_key_sequence's remapping directly.
6750 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6752 * dired.c (file_name_completion): Don't expand file name.
6753 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6754 before checking file name handler.
6756 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6757 they've been requested explicitly (bug#9591).
6759 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6761 * keymap.c (Fsingle_key_description): Use make_specified_string
6762 instead of build_string to build string from push_key_description.
6765 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6767 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6768 This fixes a Y2038 bug on 64-bit hosts.
6769 * buffer.c (reset_buffer):
6770 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6771 (Fclear_buffer_auto_save_failure):
6772 Use 0, not -1, to represent an unset failure time, since time_t
6773 might not be signed.
6775 Remove dependency on glibc malloc internals.
6776 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6777 Move back here from lisp.h, but with their new implementations.
6778 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6779 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6780 * charset.c (charset_table_init): New static var.
6781 (syms_of_charset): Use it instead of xmalloc. This removes a
6782 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6783 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6784 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6785 Move back to alloc.c.
6786 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6787 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6789 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6791 * nsterm.m (windowDidResize): Call x_set_window_size only when
6792 ns_in_resize is true. Otherwise set pixelwidth/height and
6793 call change_frame_size (Bug#9628).
6795 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6797 Port --enable-checking=all to Fedora 14 x86-64.
6798 * charset.c (syms_of_charset): Also account for glibc malloc's
6799 internal overhead when calculating the initial malloc maximum.
6801 Port --enable-checking=all to Fedora 14 x86.
6802 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6804 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6805 (overrun_check_realloc, overrun_check_free):
6806 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6807 That way, xmalloc returns a properly-aligned pointer even if
6808 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6809 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6810 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6811 into account when calculating the initial malloc maximum.
6812 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6813 Move here from alloc.c, so that charset.c can use it too.
6814 Properly align; the old code wasn't right for common 32-bit hosts
6815 when configured with --enable-checking=all.
6816 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6817 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6819 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6821 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6824 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6826 * xdisp.c (compute_display_string_end): If there's no display
6827 string at CHARPOS, return -1.
6829 * bidi.c (bidi_fetch_char): When compute_display_string_end
6830 returns a negative value, treat the character as a normal
6831 character not covered by a display string. (Bug#9624)
6833 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6835 * lread.c (Fread_from_string): Fix typo in docstring.
6837 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6839 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6840 newline, reseat the iterator instead of bidi-iterating there one
6841 character at a time. (Bug#9610)
6842 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6843 TO_CHARPOS if the bidi iterator is at base embedding level.
6845 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6847 * lread.c (readevalloop): Use correct code for NBSP.
6848 (read1): Likewise. (Bug#9608)
6850 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6852 * dbusbind.c (Fdbus_register_signal): When service is not
6853 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6855 2011-09-25 Glenn Morris <rgm@gnu.org>
6857 * buffer.c (truncate-lines): Doc fix.
6859 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6861 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6862 (Fset_window_next_buffers): Doc fix.
6864 2011-09-24 Glenn Morris <rgm@gnu.org>
6866 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6868 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6870 Fix minor problems found by static checking.
6871 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6872 * indent.c (Fvertical_motion): Fix == vs = typo.
6874 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6876 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6877 Default value is now t. Doc fix.
6879 * indent.c (Fvertical_motion): Compute and apply the overshoot
6880 logic when moving up, not only when moving down. Fix the
6881 confusing name and values of the it_overshoot_expected variable;
6882 logic changes accordingly. (Bug#9254) (Bug#9549)
6884 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6885 CHARPOS is covered by a display string which includes newlines.
6886 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6887 is covered by a display string with embedded newlines.
6889 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6891 * dbusbind.c (Fdbus_register_signal): Add match rule to
6892 Vdbus_registered_objects_table. (Bug#9581)
6893 (Fdbus_register_method, Vdbus_registered_objects_table):
6896 2011-09-24 Jim Meyering <meyering@redhat.com>
6898 do not ignore write error for any output size
6899 The previous change was incomplete.
6900 While it makes emacs --batch detect the vast majority of stdout
6901 write failures, errors were still ignored whenever the output size is
6902 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6903 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6904 && echo FAIL: ignored write error
6905 FAIL: ignored write error
6906 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6907 && echo FAIL: ignored write error
6908 FAIL: ignored write error
6909 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6911 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6913 * emacs.c (Fkill_emacs): In noninteractive mode exit
6914 non-successfully if a write error occurred on stdout. (Bug#9574)
6916 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6918 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6921 * dispextern.h (struct it): Update the comment documenting what
6924 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6926 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6927 a display string, extend search for cursor position to end of row.
6928 (find_row_edges): If the row ends in a newline from a display
6929 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6930 Handle the case of a display string with multiple newlines.
6931 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6932 non-empty line. Fixes confusing cursor motion with arrow keys at
6933 the beginning of a line that starts with whitespace.
6935 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6937 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6940 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6942 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6945 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6947 * xdisp.c (display_line): Record maximum and minimum buffer
6948 positions even if no glyphs were produced (e.g., by a zero-width
6949 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6950 buffer positions that will be removed from the glyph row because
6952 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6953 column is beyond frame width: don't subtract 1 "pixel" when
6954 computing width of the stretch.
6955 (reseat_at_next_visible_line_start): Undo the change made on
6956 2011-09-17 that saved paragraph information and restored it after
6957 the call to `reseat'. (Bug#9545)
6959 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6961 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6962 and turn window cursor on if cleared (Bug#9415).
6964 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6966 * search.c (boyer_moore): Take unibyte characters from pattern
6967 literally. (Bug#9458)
6969 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6971 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6973 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6975 Fix minor problem found by static checking.
6976 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6977 initialized, to pacify gcc -Wuninitialized.
6979 * fileio.c: Report proper errno when syscall falls.
6980 (Finsert_file_contents): Save and restore errno,
6981 so that report_file_error outputs the correct diagnostic.
6982 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6984 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6986 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6988 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6990 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6991 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6993 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6995 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6996 about the current paragraph and restore it after the call to reseat.
6998 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6999 (bidi_find_paragraph_start): Search back for paragraph beginning
7000 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7001 (bidi_move_to_visually_next): Only trigger paragraph-related
7002 computations when the last character is a newline or at EOB, not
7003 just any NEUTRAL_B. (Bug#9470)
7005 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7006 truncated lines if point is covered by a display string. (Bug#9524)
7008 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7010 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7011 (cons_to_x_long): New function.
7012 (lisp_data_to_selection_data): Use it. Correct the test for
7013 short-versus-long data; it was negated. Break out of vector
7014 loop, for efficiency, when a long datum is discovered.
7016 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7018 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7020 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7022 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7023 GCC PR/17406) by declaring this function with external scope.
7025 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7027 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7028 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7030 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7032 * editfns.c (Fformat): Correctly handle text properties on "%%".

7036 * xterm.c (x_draw_composite_glyph_string_foreground):
7037 * w32term.c (x_draw_composite_glyph_string_foreground):

7042 of TAB characters in a composition.
7044 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7046 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7047 This occurs when processing a multibyte format.
7048 Problem reported by Wolfgang Jenker.
7050 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7052 * xdisp.c (try_cursor_movement): Only check for exact match if
7053 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7055 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7057 Remove unused external symbols.
7058 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7059 * xdisp.c (calc_pixel_width_or_height): Now static.
7060 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7061 * indent.c (check_display_width):
7062 * w32term.c: Fix comment to match code.
7063 * xterm.c, xterm.h (x_catching_errors): Remove.
7065 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7067 * xselect.c: Use signed conversions more consistently (Bug#9498).
7068 (selection_data_to_lisp_data): Assume incoming selection data are
7069 signed integers, not unsigned. This is to be consistent with
7070 outgoing selection data, which was modified to use signed integers
7071 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7072 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7073 expects long, not unsigned long.
7075 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7077 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7078 computation of loop end. Reported by Johan Bockgård
7081 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7083 * frame.c (Fother_visible_frames_p): Function deleted.
7085 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7087 * indent.c (compute_motion): Process display vector front to back
7088 rather than the other way around. (Bug#2496)
7090 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7092 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7094 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7096 * minibuf.c (Fread_from_minibuffer): Doc fix.
7098 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7100 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7101 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7103 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7105 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7106 value for non-existent files.
7108 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7110 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7111 set its "size" to -1. This will set the modtime_size field of
7112 the corresponding buffer to -1, which is what
7113 verify-visited-file-modtime expects for files that do not exist.
7116 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7118 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7120 * lisp.h: ... from here. push_key_description is no longer
7121 defined in keyboard.c, so its declaration should not be in
7122 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7123 logically belongs with push_key_description.
7125 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7127 * buffer.h: Include <sys/types.h> instead of <time.h>.
7128 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7129 Problem reported by Herbert J. Skuhra.
7131 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7133 * xml.c (parse_region): Make the parsing work for
7134 non-comment-starting XML files again (bug#9144).
7136 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7138 * image.c (gif_load): Fix calculation of bottom and right corner.
7141 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7143 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7144 redisplay in small windows.
7146 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7148 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7150 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7152 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7153 Operate on live windows only.
7155 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7157 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7159 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7161 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7162 only under bidi iteration.
7164 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7166 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7168 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7170 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7171 Without this fix, the command to link temacs failed due to an
7172 undefined symbol __builtin_isnan. This is because
7173 /usr/include/iso/math_c99.h #defines isnan(x) to
7174 __builtin_isnan(x), but the bundled gcc, which identifies itself
7175 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7177 * floatfns.c (isnan): #undef, and then #define to a clone of
7179 (Fisnan): Always define, since it's always available now.
7180 (syms_of_floatfns): Always define isnan at the Lisp level.
7182 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7184 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7186 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7188 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7189 The previous code assumed that file offsets (off_t values) fit in
7190 EMACS_INT variables, which is not true on typical 32-bit hosts.
7191 The code messed up by falsely reporting buffer overflow in cases
7192 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7193 when "big" contains more than 2**29 bytes, even though this
7194 inserts just one byte and does not overflow the buffer.
7195 (Finsert_file_contents): Store file offsets as off_t
7196 values, not as EMACS_INT values. Check for overflow when
7197 converting between EMACS_INT and off_t. When checking for
7198 buffer overflow or for overlap, take the offsets into account.
7199 Don't use EMACS_INT for small values where int suffices.
7200 When checking for overlap, fix a typo: ZV was used where
7201 ZV_BYTE was intended.
7202 (Fwrite_region): Don't assume off_t fits into 'long'.
7203 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7205 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7207 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7209 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7211 sprintf-related integer and memory overflow issues (Bug#9412).
7213 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7214 (esprintf, exprintf, evxprintf): New functions.
7215 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7216 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7217 (modify_event_symbol): Do not assume that the length of
7218 name_alist_or_stem is safe to alloca and fits in int.
7219 (Fexecute_extended_command): Likewise for function name and binding.
7220 (Frecursion_depth): Wrap around reliably on integer overflow.
7221 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7222 since some callers pass EMACS_INT values.
7223 (Fsingle_key_description): Don't crash if symbol name contains more
7224 than MAX_ALLOCA bytes.
7225 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7226 (get_minibuffer): Arg is now EMACS_INT, not int.
7227 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7228 (esprintf, exprintf, evxprintf): New decls.
7229 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7231 * dbusbind.c (signature_cat): New function.
7232 (xd_signature, Fdbus_register_signal):
7233 Do not overrun buffer; instead, report string overflow.
7235 * dispnew.c (add_window_display_history): Don't overrun buffer.
7236 Truncate instead; this is OK since it's just a log.
7238 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7239 even if the time zone offset is outlandishly large.
7240 Don't mishandle offset == INT_MIN.
7242 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7243 when creating daemon; the previous buffer-overflow check was incorrect.
7245 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7246 which has the guts of the old verror function.
7248 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7249 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7251 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7252 (font_unparse_xlfd): Don't blindly alloca long strings.
7253 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7254 fits in int, when using sprintf. Use single snprintf to count
7255 length of string rather than counting it via multiple sprintfs;
7256 that's simpler and more reliable.
7257 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7258 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7259 sprintf, in case result does not fit in int.
7261 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7262 (fontset_from_font): Print it.
7264 * frame.c (tty_frame_count): Now printmax_t, not int.
7265 (make_terminal_frame, set_term_frame_name): Print it.
7266 (x_report_frame_params): In X, window IDs are unsigned long,
7267 not signed long, so print them as unsigned.
7268 (validate_x_resource_name): Check for implausibly long names,
7269 and don't assume name length fits in 'int'.
7270 (x_get_resource_string): Don't blindly alloca invocation name;
7271 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7274 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7275 (xg_check_special_colors, xg_set_geometry):
7276 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7278 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7279 Use esprintf, not sprintf, in case result does not fit in int.
7281 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7282 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7283 it as a large positive number.
7284 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7285 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7287 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7288 in case result does not fit in int.
7290 * print.c (float_to_string): Detect width overflow more reliably.
7291 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7292 buffer overrun. Don't assume list length fits in 'int'. Treat
7293 print length of 0 as 0, not as infinity; to be consistent with other
7294 uses of print length in this function. Don't overflow print length
7295 index. Don't assume hash table size fits in 'long', or that
7296 vectorlike size fits in 'unsigned long'.
7298 * process.c (make_process): Use printmax_t, not int, to format
7299 process-name gensyms.
7301 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7303 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7304 to avoid potential buffer overrun.
7306 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7307 if X resource line is longer than 512 bytes.
7309 * xfns.c (x_window): Make sprintf buffer a bit bigger
7310 to avoid potential buffer overrun.
7312 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7316 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7318 Integer overflow fixes for scrolling, etc.
7319 Without these, Emacs silently mishandles large integers sometimes.
7320 For example, "C-u 4294967297 M-x recenter" was treated as if
7321 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7323 * xdisp.c (try_window_id): Check Emacs fixnum range before
7324 converting to 'int'.
7326 * window.c (window_scroll_line_based, Frecenter):
7327 Check that an Emacs fixnum is in range before assigning it to 'int'.
7328 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7329 values converted from Emacs fixnums.
7330 (Frecenter): Don't wrap around a line count if it is out of 'int'
7331 range; instead, treat it as an extreme value.
7332 (Fset_window_configuration, compare_window_configurations):
7333 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7335 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7336 that can exceed INT_MAX. Check that EMACS_INT value is in range
7337 before assigning it to the (possibly-narrower) index.
7338 (match_limit): Don't assume that a fixnum can fit in 'int'.
7340 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7343 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7344 (Fvertical_motion): Don't wrap around LINES values that don't fit
7345 in 'int'. Instead, treat them as extreme values. This is good
7346 enough for windows, which can't have more than INT_MAX lines anyway.
7348 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7350 * Require libxml/parser.h to avoid compilation warning.
7352 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7354 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7355 since this reportedly can destroy thread storage.
7357 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7359 * syntax.c (find_defun_start): Update all cache variables if
7360 exiting early (Bug#9401).
7362 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7364 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7366 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7367 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7368 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7370 * term.c (tty_append_glyph): New function.
7371 (produce_stretch_glyph): Static function and its prototype deleted.
7373 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7376 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7378 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7379 when checking :margin (Bug#9390).
7380 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7381 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7382 so that the name doesn't mislead. All uses changed.
7384 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7386 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7389 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7391 * xdisp.c (move_it_to): Don't bail out early when reaching
7392 position beyond to_charpos, if we are scanning backwards.
7393 (move_it_vertically_backward): When DY == 0, make sure we get to
7394 the first character in the line after the newline.
7396 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7398 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7399 (ccl_driver): Do not generate an out-of-range pointer.
7400 (Fccl_execute_on_string): Remove unnecessary check for
7401 integer overflow, noted by Stefan Monnier in
7402 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7403 Remove a FIXME that didn't need fixing.
7404 Simplify the newly-introduced buffer reallocation code.
7406 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7408 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7410 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7412 Integer and memory overflow issues (Bug#9196).
7414 * doc.c (get_doc_string): Rework so that
7415 get_doc_string_buffer_size is the actual buffer size, rather than
7416 being 1 less than the actual buffer size; this makes xpalloc more
7419 * image.c (x_allocate_bitmap_record, cache_image):
7420 * xselect.c (Fx_register_dnd_atom):
7421 Simplify previous changes by using xpalloc.
7423 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7424 since either will do and ptrdiff_t is convenient with xpalloc.
7426 * charset.c (charset_table_size)
7427 (struct charset_sort_data.priority): Now ptrdiff_t.
7428 (charset_compare): Don't overflow if priorities differ greatly.
7429 (Fsort_charsets): Don't assume list length fits in int.
7430 Check for size-calculation overflow when allocating sort data.
7431 (syms_of_charset): Allocate an initial charset table that is
7432 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7434 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7436 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7437 The actual value is always <= INT_MAX, and leaving it unsigned made
7438 overflow checking harder.
7440 * dispextern.h (struct glyph_matrix.rows_allocated)
7441 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7442 with xpalloc. The values are still always <= INT_MAX.
7444 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7446 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7447 (SAFE_NALLOCA): New macro.
7449 * region-cache.c (struct boundary.pos, find_cache_boundary)
7450 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7451 (set_cache_region, invalidate_region_cache)
7452 (revalidate_region_cache, know_region_cache, region_cache_forward)
7453 (region_cache_backward, pp_cache):
7454 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7455 so that ptrdiff_t * can be passed to xpalloc.
7456 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7457 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7458 (pp_cache): Don't assume cache_len fits in int.
7459 * region-cache.h: Adjust extern decls to match.
7461 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7462 EMACS_INT, since either will do, for xpalloc.
7464 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7465 (xnmalloc, xnrealloc, xpalloc): New functions.
7467 * bidi.c (bidi_shelve_header_size): New constant.
7468 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7469 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7471 * bidi.c (bidi_cache_shrink):
7472 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7474 Don't update size of array until after memory allocation succeeds,
7475 because xmalloc/xrealloc may not return.
7476 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7477 now that we have proper integer overflow checking.
7478 (record_overlay_string, overlay_strings): Catch overflows when
7479 calculating size of overlay_str_buf.
7481 * callproc.c (Fcall_process): Check for size overflow when
7482 calculating size of args2.
7483 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7484 Normally we prefer signed values, but sticking with ptrdiff_t would
7485 require adding more-complicated checks.
7487 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7488 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7489 Redo buffer-overflow calculations to avoid integer overflow.
7490 Add a FIXME comment where memory seems to be over-allocated.
7492 * character.c (Fstring): Check for size-calculation overflow.
7494 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7495 unnecessary integer overflow. Check for size overflow.
7496 (encode_coding_object): Don't update size until xmalloc succeeds.
7498 * composite.c (get_composition_id): Check for overflow in glyph
7499 length calculations.
7501 Integer and memory overflow fixes for display code.
7502 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7503 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7504 (scrolling_window): Check for overflow in size calculations.
7505 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7517 (get_doc_string): Check for size calculation overflow.
7518 Don't update size until allocation succeeds.
7519 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7520 EMACS_INT, where ptrdiff_t will do.
7521 (Fsubstitute_command_keys): Check for string overflow.
7523 * editfns.c (set_time_zone_rule): Don't assume environment length
7525 (message_length): Now ptrdiff_t, not int.
7526 (Fmessage_box): Don't update size until allocation succeeds.
7527 Don't assume message length fits in int.
7528 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7530 * emacs.c (main): Do not reallocate argv, since there is a null at
7531 the end that can be overwritten, and this way there's no need to
7532 worry about size-calculation overflow.
7533 (sort_args): Check for size-calculation overflow.
7535 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7537 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7539 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7540 (x_set_scroll_bar_width, x_figure_window_size):
7541 Check for integer overflow.
7542 (x_set_alpha): Do not assume XINT fits in int.
7544 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7545 This is for the members text_lines, text_cols, total_lines, total_cols,
7546 where the system imposes an 'int' limit.
7548 * fringe.c (Fdefine_fringe_bitmap):
7549 Don't update size until alloc works.
7551 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7552 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7554 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7555 Check for size-calculation overflow.
7556 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7557 do, as we prefer signed integers.
7558 (id_to_widget.max_size, id_to_widget.used)
7559 (xg_store_widget_in_map, xg_remove_widget_from_map)
7560 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7561 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7562 Use and return ptrdiff_t, not int.
7563 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7564 * gtkutil.h: Change prototypes to match the above.
7566 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7567 are duplicate now that they've been promoted to lisp.h.
7568 (x_allocate_bitmap_record, x_alloc_image_color)
7569 (make_image_cache, cache_image, xpm_load):
7570 Don't update size until alloc is done.
7571 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7573 Check for size calculation overflow.
7574 (ct_colors_allocated_max): New constant.
7575 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

7580 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7581 Use ptrdiff_t, not int, to count maps.
7582 (read_char_minibuf_menu_prompt): Check for overflow in size
7583 calculations. Don't update size until allocation succeeds.

7595 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7597 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7598 Now ptrdiff_t, not int.
7599 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

7610 * search.c (Freplace_match): Check for size calculation overflow.
7611 (Fset_match_data): Don't assume list lengths fit in 'int'.
7613 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7614 for command line length. Do not attempt to address one before the
7615 beginning of an array, as that's not portable.

7618 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7620 (encode_terminal_code, calculate_costs): Check for size
7621 calculation overflow.

7623 table lengths and related sizes. Don't update size until alloc
7624 done. Redo calculations to avoid overflow.
7625 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7627 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7643 Use ptrdiff_t, not int, for sizes.
7644 (Finternal_make_lisp_face, cache_face):
7645 Check for size calculation overflow.
7646 (cache_face): Treat size calculation overflows as if they were
7647 memory exhaustion (the usual treatment), rather than aborting.
7649 * xfns.c (x_encode_text, x_set_name_internal)
7650 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7651 sizes, since they can exceed INT_MAX in size. Check for size
7652 calculation overflow.
7654 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
7655 (xg_select): Check for size calculation overflow.
7656 Don't update size until alloc done.
7658 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7659 as sprintf is limited to int lengths.
7661 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7662 (X_LONG_MIN): New macros.
7663 Use them to make the following changes clearer.
7664 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7665 This change doesn't affect the value now, but it may help remind
7666 future maintainers not to raise the value too much later.
7667 (SELECTION_QUANTUM): Remove, replacing with ...
7668 (selection_quantum): ... new function, which avoids overflow.
7670 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7671 assumption that selection length fits in 'int'.
7672 (x_reply_selection_request, x_handle_selection_request)
7673 (x_get_window_property, receive_incremental_selection)
7674 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7675 (lisp_data_to_selection_data, clean_local_selection_data):

7679 Redo calculations to avoid overflow.
7680 (x_reply_selection_request): When sending hint, ceiling it at
7681 X_LONG_MAX rather than relying on wraparound overflow to send

7684 (lisp_data_to_selection_data, x_property_data_to_lisp):
7685 Check for size-calculation overflow.
7686 (x_get_window_property, receive_incremental_selection)

7688 Don't store size until memory allocation succeeds.
7689 (x_get_window_property): Plug memory leak on memory exhaustion.
7690 Don't double-block input; malloc is safe here. Don't assume 2**34
7691 - 4 fits in unsigned long. Add an xassert to check
7692 XGetWindowProperty overflow. Be more careful about overflow
7693 calculations, and distinguish size from memory overflow better.
7694 (receive_incremental_selection): When tracing, don't assume
7695 unsigned int is less than INT_MAX.
7696 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7697 harmful) conversions of unsigned short to int.
7698 (lisp_data_to_selection_data): Don't assume that integers
7699 in the range -65535 through -1 fit in an X unsigned short.
7700 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7701 result parameters unless successful. Rely on cons_to_unsigned
7702 to report problems with elements; the old code wasn't right anyway.
7703 (x_check_property_data): Check for int overflow; we cannot use
7704 a wider type due to X limits.
7705 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7736 * image.c (xpm_get_color_table_h):
7737 * lisp.h (hash_lookup, hash_put):
7738 * minibuf.c (Ftest_completion):
7739 Use ptrdiff_t for hash table indexes, not int (which is too
7740 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7741 32-bit --with-wide-int hosts).
7743 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7744 Add a FIXME comment about memory leaks.
7745 (syms_of_charset): Don't assume xmalloc returns.
7747 Don't assume that stated character widths fit in int.
7748 * character.c (Fchar_width, c_string_width, lisp_string_width):
7749 * character.h (CHAR_WIDTH):
7750 * indent.c (MULTIBYTE_BYTES_WIDTH):
7751 Use sanitize_char_width to avoid undefined and/or bad behavior
7752 with outlandish widths.
7753 * character.h (sanitize_tab_width): Rename from sanitize_width,
7754 now that we have two such functions. All uses changed.
7755 (sanitize_char_width): New inline function.
7757 Don't assume that tab-width fits in int.
7758 * character.h (sanitize_width): New inline function.
7759 (SANE_TAB_WIDTH): New macro.

7765 * fileio.c: Integer overflow issues with file modes.
7766 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

7773 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7774 (x_send_scroll_bar_event): Likewise. Check that the size does not
7775 exceed limits imposed by XClientMessageEvent, as well as the usual
7776 ptrdiff_t and size_t limits.
7778 * keyboard.c: Overflow, signedness and related fixes.
7779 (make_lispy_movement): Use same integer type in forward decl
7780 that is used in the definition.
7781 (read_key_sequence, keyremap_step):
7782 Change bufsize argument back to int, undoing my 2011-03-30 change.
7783 We prefer signed types, and int is wide enough here.
7784 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7785 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7786 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7787 length, not size_t. Use ptrdiff_t for index, not int.
7788 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7789 possibility of integer overflow.
7791 Overflow, signedness and related fixes for images.

7812 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7813 (lookup_image): Remove unnecessary tests.
7814 (xbm_image_p): Locals are now of int, not EMACS_INT,
7815 since parse_image_check makes sure they fit into int.
7816 (png_load, gif_load, svg_load_image):
7817 Prefer int to unsigned where either will do.
7818 (tiff_handler): New function, combining the cores of the
7819 old tiff_error_handler and tiff_warning_handler.
7820 This function is rewritten to use vsnprintf and thereby avoid
7821 stack buffer overflows. It uses only the features of vsnprintf
7822 that are common to both POSIX and native Microsoft.
7823 (tiff_error_handler, tiff_warning_handler): Use it.
7824 (tiff_load, gif_load, imagemagick_load_image):
7825 Don't assume :index value fits in 'int'.
7826 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7827 (imagemagick_load_image): Check that crop parameters fit into
7828 the integer types that MagickCropImage accepts. Don't assume
7829 Vimagemagick_render_type has a nonnegative value. Don't assume
7830 size_t fits in 'long'.
7831 (gs_load): Use printmax_t to print the widest integers possible.
7832 Check for integer overflow when computing image height and width.

7841 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7842 the display spec is of the form `(space ...)'.
7843 (handle_display_spec): Return the value returned by
7844 handle_single_display_spec, not just 1 or zero.
7845 (handle_single_display_spec): If the display spec is of the form
7846 `(space ...)', and specifies display in the text area, return 2
7848 (try_cursor_movement): Check for the need to scroll more
7849 accurately, and prefer exact match for point under bidi.
7850 Don't advance `row' beyond the last row of the window.
7852 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7853 into disp_prop; all users changed.
7855 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7856 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7857 for the text covered by the display property.
7859 2011-08-25 Chong Yidong <cyd@stupidchicken.com>

7868 buffers, return left-to-right.
7869 (set_cursor_from_row): Consider candidate row a win if its glyph
7870 represents a newline and point is on that newline. Fixes cursor
7871 positioning on the newline at EOL of R2L text within L2R
7872 paragraph, and vice versa.
7873 (try_cursor_movement): Check continued rows, in addition to
7874 continuation rows. Fixes unwarranted scroll when point enters a
7875 continued line of R2L text within an L2R paragraph, or vice versa.
7876 (cursor_row_p): Consider the case of point being equal to
7877 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7878 from the end of a short line to the beginning of a continued line
7879 of R2L text within L2R paragraph.
7880 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7881 composed characters.
7883 * bidi.c (bidi_check_type): Use xassert.
7884 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p

7896 2011-08-22 Kenichi Handa <handa@m17n.org>
7898 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7899 extra slot even if the purpose is char-code-property-table.
7901 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7903 * xdisp.c (redisplay_window): When computing centering_position,
7904 account for the height of the header line. (Bug#8874)
7906 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7907 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7908 candidate is selected by the mouse, and that candidate has a
7909 composed character under the mouse.
7911 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7912 coordinates reported by pos-visible-in-window-p for a composed
7913 character in column zero.

7919 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7921 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7922 consider it a hit if to_charpos is anywhere in the range of the
7923 composed buffer positions.
7925 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7927 * image.c (gif_load): Don't assume that each subimage has the same
7928 dimensions as the base image. Handle disposal method that is
7929 "undefined" by the gif spec (Bug#9335).
7931 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7933 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

7936 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7938 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7939 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7940 from an Org mode buffer to a Speedbar frame.
7942 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7943 a composition, take its buffer position from IT->cmp_it.charpos.
7944 Fixes cursor positioning at the beginning of a line that begins
7945 with a composed character.
7947 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7949 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7950 character bidirectional type, use STRONG_L instead. Fixes crashes
7951 in a buffer produced by `describe-categories'.
7953 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7954 members before the level stack, so they would be saved and
7955 restored when copying iterator state. Fixes incorrect reordering
7956 around TABs covered by display properties.
7958 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8032 ppos_it. Fixes vertical cursor motion when line beginning is
8033 covered by an image. (Bug#9296)
8035 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8037 * nsterm.h (ns_run_ascript): Declare.

8041 (ns_run_ascript): New function.
8042 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8043 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8044 the event loop. Get status from as_status (Bug#7276).
8046 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8047 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8048 the event loop (Bug#7276).

8074 (Fnetwork_interface_list): Allocate in increments of bytes instead
8075 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8076 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8078 (struct ifflag_def): notrailers is smart on OSX.
8079 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8080 Get hardware address with getifaddrs if available.
8082 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8084 * xdisp.c (iterate_out_of_display_property): xassert that
8085 IT->position is set to within IT->object's boundaries. Break from
8086 the loop as soon as EOB is reached; avoids infloops in redisplay
8087 when IT->position is set up wrongly due to some bug.
8088 Set IT->current to match the bidi iterator unconditionally.
8089 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8090 entry. Force push_it to save on the stack the current
8091 buffer/string position, to be restored by pop_it. Fix flags in
8092 the iterator structure wrt the object coming from a display
8093 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8094 properties. (Bug#9284)
8096 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8098 * fontset.c (fontset_get_font_group): Add proper type checks.

8111 no-display-properties-and-no-overlays under bidi display.
8112 Set disp_pos in the bidi iterator to avoid searches for display
8113 properties and overlays.
8115 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8117 * editfns.c (Fset_time_zone_rule): Document relationship with the

8126 restore_point_unwind (Bug#5984).
8128 2011-08-07 Juri Linkov <juri@jurta.org>
8130 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8131 to show the arg `TIME' instead of `TIMEVAL'.

8137 longlines-mode. (Bug#9254)
8138 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8139 word-wrap under bidirectional display. (Bug#9224)
8141 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8142 is non-zero, even if the data buffer is NULL. Fixes a crash in
8143 vertical-motion with longlines-mode. (Bug#9254)
8145 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8147 * bidi.c <bidi_cache_total_alloc>: Now static.
8148 (bidi_initialize): Initialize bidi_cache_total_alloc.
8150 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8153 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8154 amount allocated this far in `bidi_cache_total_alloc'.
8155 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8156 non-zero, only free the data buffer without restoring the cache
8157 contents. All callers changed.
8159 * dispextern.h (bidi_unshelve_cache): Update prototype.
8161 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8162 (move_it_in_display_line, move_it_to)
8163 (move_it_vertically_backward, move_it_by_lines): Replace the call
8164 to xfree to an equivalent call to bidi_unshelve_cache.
8165 (move_it_in_display_line_to): Fix logic of returning
8166 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8168 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8170 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8171 came from a string character with a `cursor' property. (Bug#9229)

8203 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8204 so that it is not optimized away.
8206 * xdisp.c (compute_display_string_pos): Remove unused local.
8208 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8210 Fix slow cursor motion and scrolling in large buffers with
8211 selective display, like Org Mode buffers. (Bug#9218)
8213 * dispextern.h (struct bidi_it): New member disp_prop_p.
8215 * xdisp.c: Remove one-slot cache of display string positions.
8216 (compute_display_string_pos): Accept an additional argument
8217 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8218 for a display string or property. If found, set DISP_PROP_P
8221 * bidi.c (bidi_fetch_char): Accept an additional argument
8222 DISP_PROP_P, and pass it to compute_display_string_pos.
8223 Only handle text covered by a display string if DISP_PROP_P is returned
8224 non-zero. All callers of bidi_fetch_char changed.
8226 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8228 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8230 2010-12-03 Don March <don@ohspite.net>
8232 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8233 last character M-[char] is translated to ESC [char] (bug#7541).
8235 2011-08-02 Kenichi Handa <handa@m17n.org>
8237 * lisp.h (uniprop_table): Extern it.
8239 * chartab.c (uniprop_table): Make it non-static.
8241 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8243 * xdisp.c (forward_to_next_line_start): Accept additional argument
8244 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8246 (reseat_at_next_visible_line_start): Use the bidi iterator state
8247 returned by forward_to_next_line_start to restore the state of
8248 it->bidi_it after backing up to previous newline. (Bug#9212)
8250 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8252 * regex.c (re_comp): Protoize.
8253 (re_exec): Fix return type.
8254 (regexec): Fix type of `ret'. (Bug#9203)
8256 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8258 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8259 This is needed if max-image-size is a floating-point number.
8261 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8263 * print.c (print_object): Print empty symbol as ##.
8265 * lread.c (read1): Read ## as empty symbol.
8267 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8269 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8270 setting frame foreground color (Bug#9175).
8271 (x_set_background_color): Likewise.
8273 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8274 contents (Bug#9176).
8275 (EmacsTooltip -init): Remove bezels and add shadows to
8278 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8279 or scroll bar (Bug#8470).
8281 * nsfont.m (nsfont_open): Remove assignment to voffset and
8282 unnecessary vars hshink, expand, hd, full_height, min_height.
8283 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8285 * nsterm.h (nsfont_info): Remove voffset field.
8287 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8289 Implement strike-through and overline on NextStep (Bug#8863).
8291 * nsfont.m (nsfont_open): Use underline position provided by font,
8292 instead of hard-coded value of 2.
8293 (nsfont_draw): Call ns_draw_text_decoration instead.
8295 * nsterm.h: Add declaration for ns_draw_text_decoration.
8297 * nsterm.m (ns_draw_text_decoration): New function for drawing
8298 underline, overline, and strike-through.
8299 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8300 ns_draw_text_decoration. Change treatment of cursor drawing to
8301 accommodate underlining, etc.
8303 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8305 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8308 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8310 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8311 Without this fix, if a signal arrives just after memory fills up,
8312 'malloc' might be invoked reentrantly.
8314 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8315 In other words, assume that every image size is allowed, on non-X
8316 hosts. This assumption is probably wrong, but it lets Emacs compile.
8318 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8320 * regex.c (re_iswctype): Convert return values to boolean.
8322 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8324 * xdisp.c (compute_display_string_pos): Don't use cached display
8325 string position if the buffer had its restriction changed.
8328 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8330 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8332 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8334 Integer signedness and overflow and related fixes. (Bug#9079)
8336 * bidi.c: Integer size and overflow fixes.
8337 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8338 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8339 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8340 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8341 (bidi_find_other_level_edge):
8342 Use ptrdiff_t instead of EMACS_INT where either will do.
8343 This works better on 32-bit hosts configured --with-wide-int.
8344 (bidi_cache_ensure_space): Check for size-calculation overflow.
8345 Use % rather than repeated addition, for better worst-case speed.
8346 Don't set bidi_cache_size until after xrealloc returns, because it
8348 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8349 (bidi_cache_ensure_space): Also check that the bidi cache size
8350 does not exceed that of the largest Lisp string or buffer. See Eli
8351 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8353 * alloc.c (__malloc_size_t): Remove.
8354 All uses replaced by size_t. See Andreas Schwab's note
8355 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8357 * image.c: Improve checking for integer overflow.
8358 (check_image_size): Assume that f is nonnull, since
8359 it is always nonnull in practice. This is one less thing to
8360 worry about when checking for integer overflow later.
8361 (x_check_image_size): New function, which checks for integer
8362 overflow issues inside X.
8363 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8364 This removes the need for a memory_full check.
8365 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8366 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8367 (xbm_read_bitmap_data): Change locals back to 'int', since
8368 their values must fit in 'int'.
8369 (xpm_load_image, png_load, tiff_load):
8370 Invoke x_create_x_image_and_pixmap earlier,
8371 to avoid much needless work if the image is too large.
8372 (tiff_load): Treat overly large images as if
8373 x_create_x_image_and_pixmap failed, not as malloc failures.
8374 (gs_load): Use x_check_image_size.
8376 * gtkutil.c: Omit integer casts.
8377 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8378 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8380 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8382 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8383 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8384 would wrongly return t on a 64-bit host.
8386 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8387 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8388 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8389 and therefore cause GCC to emit a bogus diagnostic in some cases.
8391 * image.c: Integer signedness and overflow and related fixes.
8392 This is not an exhaustive set of fixes, but it's time to
8393 record what I've got.
8394 (lookup_pixel_color, check_image_size): Remove redundant decls.
8395 (check_image_size): Don't assume that arbitrary EMACS_INT values
8396 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8397 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8398 (tiff_load, imagemagick_load_image):
8399 Check for overflow in size calculations.
8400 (x_create_x_image_and_pixmap): Remove unnecessary test for
8401 xmalloc returning NULL; that can't happen.
8402 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8403 (xpm_color_bucket): Use better integer hashing function.
8404 (xpm_cache_color): Don't possibly over-allocate memory.
8405 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8406 (gif_memory_source):
8407 Use ptrdiff_t, not int or size_t, to record sizes.
8408 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8409 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8410 either works, as we prefer signed integers.
8411 (tiff_read_from_memory, tiff_write_from_memory):
8412 Return tsize_t, not size_t, since that's what the TIFF API wants.
8413 (tiff_read_from_memory): Don't fail simply because the read would
8414 go past EOF; instead, return a short read.
8415 (tiff_load): Omit no-longer-needed casts.
8416 (Fimagemagick_types): Don't assume size fits into 'int'.
8418 Improve hashing quality when configured --with-wide-int.
8419 * fns.c (hash_string): New function, taken from sxhash_string.
8420 Do not discard information about ASCII character case; this
8421 discarding is no longer needed.
8422 (sxhash-string): Use it. Change sig to match it. Caller changed.
8423 * lisp.h: Declare it.
8424 * lread.c (hash_string): Remove, since we now use fns.c's version.
8425 The fns.c version returns a wider integer if --with-wide-int is
8426 specified, so this should help the quality of the hashing a bit.
8428 * emacs.c: Integer overflow minor fix.
8429 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8430 Define only if GNU_LINUX.
8431 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8433 * dispnew.c: Integer signedness and overflow fixes.
8434 Remove unnecessary forward decls, that were a maintenance hassle.
8435 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8437 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8438 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8439 (prepare_desired_row, line_draw_cost):
8440 Use int, not unsigned, where either works.
8441 (save_current_matrix, restore_current_matrix):
8442 Use ptrdiff_t, not size_t, where either works.
8443 (init_display): Check for overflow more accurately, and without
8444 relying on undefined behavior.
8446 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8447 Remove, replacing with the new symbols in lisp.h. All uses changed.
8448 * fileio.c (make_temp_name):
8449 * filelock.c (lock_file_1, lock_file):
8450 * xdisp.c (message_dolog):
8451 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8452 Use pMd etc. instead.
8453 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8454 replacing the pWIDE etc. symbols removed from editfns.c.
8456 * keyboard.h (num_input_events): Now uintmax_t.
8457 This is (very slightly) less likely to mess up due to wraparound.
8460 * buffer.c: Integer signedness fixes.
8461 (alloc_buffer_text, enlarge_buffer_text):
8462 Use ptrdiff_t rather than size_t when either will do, as we prefer
8465 * alloc.c: Integer signedness and overflow fixes.
8466 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8467 (__malloc_size_t): Default to size_t, not to int.
8468 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8469 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8470 Prefer ptrdiff_t to size_t when either would do, as we prefer
8472 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8473 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8474 Now const. Initialize with values that are in range even if char
8476 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8477 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8478 These functions do the right thing with sizes > 2**32.
8479 (check_depth): Now ptrdiff_t, not int.
8480 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8481 Adjust to new way of storing sizes. Check for size overflow bugs
8483 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8484 slightly wrong anyway, as it missed one instance of
8485 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8486 (refill_memory_reserve): Omit needless cast to size_t.
8487 (mark_object_loop_halt): Mark as externally visible.
8489 * xselect.c: Integer signedness and overflow fixes.
8490 (Fx_register_dnd_atom, x_handle_dnd_message):
8491 Use ptrdiff_t, not size_t, since we prefer signed.
8492 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8493 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8494 x_dnd_atoms_size and x_dnd_atoms_length.
8496 * doprnt.c: Prefer signed to unsigned when either works.
8498 * doprnt.c (doprnt):
8500 * xdisp.c (vmessage):
8501 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8502 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8503 prefer signed arithmetic to avoid comparison confusion.
8504 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8505 but is a bit tricky.
8507 Assume freestanding C89 headers, string.h, stdlib.h.
8508 * data.c, doprnt.c, floatfns.c, print.c:
8509 Include float.h unconditionally.
8510 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8511 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8512 * regex.c: Likewise for stddef.h, string.h.
8513 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8514 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8515 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8516 (STDC_HEADERS): Remove obsolete defines.
8517 * sysdep.c: Include limits.h unconditionally.
8519 Assume support for memcmp, memcpy, memmove, memset.
8520 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8521 * regex.c (memcmp, memcpy):
8522 Remove; we assume C89 now.
8524 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8525 (__malloc_safe_bcopy): Remove; no longer needed.
8527 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8528 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8529 well either way, and we prefer signed to unsigned.
8531 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8533 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8534 closes the connection while we're reading (bug#9182).
8536 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8538 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8539 are specified (Bug#9168).
8541 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8543 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8544 Found by GCC static checking and --with-wide-int on a 32-bit host.
8546 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8548 * xdisp.c (compute_display_string_pos): Fix logic of caching
8549 previous display string position. Initialize cached_prev_pos to
8550 -1. Fixes slow-down at the beginning of a buffer.
8552 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8554 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8555 for attrs[LFACE_FONTSET_INDEX].
8557 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8559 * xml.c (parse_region): Remove unused local
8560 that was recently introduced.
8562 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8564 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8565 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8567 * xdisp.c (move_it_in_display_line_to): Record the best matching
8568 position for TO_CHARPOS while scanning the line, and restore it on
8569 exit if none of the characters scanned was an exact match.
8570 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8571 when exact match is impossible due to invisible text, and the
8572 lines are truncated.
8574 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8576 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8579 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8581 Fix a significant slow-down of cursor motion with C-n, C-p,
8582 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8583 auto-repeat under bidi redisplay in fontified buffers.
8584 * xdisp.c (compute_stop_pos_backwards): New function.
8585 (next_element_from_buffer): Call compute_stop_pos_backwards to
8586 find a suitable prev_stop when we find ourselves before
8588 (reseat): Don't look for prev_stop, as that could mean a very long
8590 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8591 <cached_disp_overlay_modiff>: Cache for last found display string
8593 (compute_display_string_pos): Return the cached position if asked
8594 about the same buffer in the same area of character positions, and
8595 the buffer wasn't changed since the time the display string
8596 position was cached.
8598 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8600 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8601 is an integer, which is important for empty lines. (Bug#9149)
8603 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8605 * frame.c (Fmodify_frame_parameters): In tty case, update the
8606 default face if necessary (Bug#4238).
8608 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8610 * editfns.c (Fstring_to_char): No need to explain what a character
8611 is in the docstring (Bug#6576).
8613 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8615 * xml.c (parse_region): Make sure we always return a tree.
8617 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8619 * xml.c (parse_region): If a document contains only comments,
8622 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8624 * xml.c (make_dom): Return comments, too.
8626 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8629 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8630 and the surrounding thread.
8631 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8632 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8633 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8635 * s/openbsd.h (BROKEN_SIGIO): Define.
8636 * unexelf.c (unexec) [__OpenBSD__]:
8637 Don't update the .mdebug section of the Alpha COFF symbol table.
8639 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8641 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8644 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8646 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8647 This fixes some race conditions on the permissions of any newly
8650 * alloc.c (valid_pointer_p): Use pipe, not open.
8651 This fixes some permissions issues when debugging.
8653 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8654 If fchown fails to set both uid and gid, try to set just gid,
8655 as that is sometimes allowed. Adjust the file's mode to eliminate
8656 setuid or setgid bits that are inappropriate if fchown fails.
8658 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8660 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8661 to compare Lisp_Objects.
8662 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8663 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8664 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8666 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>

8676 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8677 This works around a problem with the previous change to Fcopy_file.
8678 Recent glibc declares fchown with __attribute__((warn_unused_result)),

8680 fchown's return value.
8682 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8684 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

8728 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8729 "cannot optimize loop, the loop counter may overflow", a symptom
8731 * indent.c (Fvertical_motion): Mark locals as initialized.
8732 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8734 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

8778 the iterator is before prev_stop.
8779 (init_iterator): Initialize bidi_p from the default value of

9297 Random fixes. E.g., (random) never returned negative values.
9298 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9299 subseconds part to the entropy, as that's a bit more random.
9300 Prefer signed to unsigned, since the signedness doesn't matter and
9301 in general we prefer signed. When given a limit, use a
9302 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9303 latter isn't right if USE_2_TAGS_FOR_INTS.
9304 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9305 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9318 This is more efficient than Ffile_directory_p and avoids a minor race.
9320 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9322 * buffer.c (Foverlay_put): Say what the return value is
9325 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9328 (barf_or_query_if_file_exists): Make the "File is a directory"
9329 error be more correct.
9331 * fns.c (Frequire): Remove the mention of the .gz files, since
9332 that's installation-specific, but keep the mention of
9333 `get-load-suffixes'.

9337 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9348 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9450 * eval.c (struct backtrace): Simplify and port the data structure.
9451 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9452 signed bit field, as this assumption is not portable and it makes
9453 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9454 "char debug_on_exit : 1" as this is not portable either; instead,
9455 use the portable "unsigned int debug_on_exit : 1". Remove unused
9456 member evalargs. Remove obsolete comments about cc bombing out.

9618 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
9620 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9622 Integer and buffer overflow fixes (Bug#8873).
9624 * print.c (printchar, strout): Check for string overflow.
9625 (PRINTPREPARE, printchar, strout):
9626 Don't set size unless allocation succeeds.
9628 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9629 for sizes. Check for string overflow more accurately.
9630 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
9632 * macros.c: Integer and buffer overflow fixes.
9633 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9634 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
9635 Use ptrdiff_t, not int, for sizes.
9636 Don't increment bufsize until after realloc succeeds.
9637 Check for size-calculation overflow.
9638 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
9640 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9642 * lread.c: Integer overflow fixes.
9643 (read_integer): Radix is now EMACS_INT, not int,
9644 to improve quality of diagnostics for out-of-range radices.
9645 Calculate buffer size correctly for out-of-range radices.
9646 (read1): Check for integer overflow in radices, and in
9647 read-circle numbers.
9648 (read_escape): Avoid int overflow.
9649 (Fload, openp, read_buffer_size, read1)
9650 (substitute_object_recurse, read_vector, read_list, map_obarray):
9651 Use ptrdiff_t, not int, for sizes.
9652 (read1): Use EMACS_INT, not int, for sizes.
9653 Check for size overflow.
9655 * image.c (cache_image): Check for size arithmetic overflow.
9657 * lread.c: Integer overflow issues.
9658 (saved_doc_string_size, saved_doc_string_length)
9659 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9660 Now ptrdiff_t, not int.
9661 (read1): Don't assume doc string length fits in int. Check for
9662 out-of-range doc string lengths.
9663 (read_list): Don't assume file position fits in int.
9664 (read_escape): Check for hex character overflow.
9666 2011-06-22 Leo Liu <sdl.web@gmail.com>
9668 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9669 Move to minibuffer.el.
9671 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9673 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9674 The following patches are for when GLYPH_DEBUG && !XASSERT.
9675 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9676 * dispnew.c (flush_stdout):
9677 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9678 Mark as externally visible.
9679 * dispnew.c (check_window_matrix_pointers): Now static.
9680 * dispnew.c (window_to_frame_vpos):
9681 * xfns.c (unwind_create_frame):
9682 * xterm.c (x_check_font): Remove unused local.
9683 * scroll.c (CHECK_BOUNDS):
9684 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9685 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9686 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9687 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9688 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9690 (debug_method_add): Use va_list and vsprintf rather than relying
9691 on undefined behavior with wrong number of arguments.
9692 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9693 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9694 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9695 since we're not interested in debugging glyphs with old libraries.
9696 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9697 GCC 4.6.0's static checking.
9699 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9701 Integer overflow and signedness fixes (Bug#8873).
9702 A few related buffer overrun fixes, too.
9704 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
9706 * dispextern.h (struct face.stipple):
9707 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9708 (x_bitmap_mask, x_allocate_bitmap_record)
9709 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9710 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9711 (x_create_bitmap_from_xpm_data):
9712 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9713 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9715 * xfaces.c (load_pixmap):
9716 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9717 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9718 (.bitmaps_last, struct x_output.icon_bitmap):
9719 Use ptrdiff_t, not int, for bitmap indexes.
9720 (x_allocate_bitmap_record): Check for size overflow.
9721 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9723 Use ptrdiff_t, not int, for overlay counts.
9724 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9725 * editfns.c (overlays_around, get_pos_property):
9726 * textprop.c (get_char_property_and_overlay):
9727 * xdisp.c (next_overlay_change, note_mouse_highlight):
9728 * xfaces.c (face_at_buffer_position):
9729 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9730 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9731 (Fnext_overlay_change, Fprevious_overlay_change)
9732 (mouse_face_overlay_overlaps, Foverlays_in):
9733 Use ptrdiff_t, not int, for sizes.
9734 (overlays_at, overlays_in): Check for size-calculation overflow.
9736 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9738 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9739 (x_session_initialize): Do not assume string length fits in int.
9741 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9742 This is unlikely, but can occur if DPI is outlandish.
9744 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9745 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9747 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9748 * xrdb.c (magic_file_p, search_magic_path):
9749 Omit last arg SUFFIX; it was always 0. All callers changed.
9750 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9752 * xfont.c (xfont_match): Avoid need for strlen.
9754 * xfns.c: Don't assume strlen fits in int.
9755 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9757 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9758 not unsigned long, as we prefer signed integers. All callers changed.
9759 Detect integer overflow in repeat count.
9760 (message_dolog): Don't assume print length fits in 39 bytes.
9761 (display_mode_element): Don't assume strlen fits in int.
9763 * termcap.c: Don't assume sizes fit in int and never overflow.
9764 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9765 (gobble_line): Check for size-calculation overflow.
9767 * minibuf.c (Fread_buffer):
9768 * lread.c (intern, intern_c_string):
9769 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9770 Don't assume string length fits in int.
9772 * keyboard.c (parse_tool_bar_item):
9773 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9775 * font.c: Don't assume string length fits in int.
9776 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9777 Use ptrdiff_t, not int.
9778 (font_intern_prop): Don't assume string length fits in int.
9779 Don't assume integer property fits in fixnum.
9780 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9782 * filelock.c: Fix some buffer overrun and integer overflow issues.
9783 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9784 Reformulate so as not to need the command string.
9785 Invoke gzip -cd rather than gunzip, as it's more portable.
9786 (lock_info_type, lock_file_1, lock_file):
9787 Don't assume pid_t and time_t fit in unsigned long.
9788 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9789 (current_lock_owner): Prefer signed type for sizes.
9790 Use memcpy, not strncpy, where memcpy is what is really wanted.
9791 Don't assume (via atoi) that time_t and pid_t fit in int.
9792 Check for time_t and/or pid_t out of range, e.g., via a network share.
9793 Don't alloca where an auto var works fine.
9795 * fileio.c: Fix some integer overflow issues.
9796 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9797 Don't assume string length fits in int.
9798 (directory_file_name): Don't assume string length fits in long.
9799 (make_temp_name): Don't assume pid fits in int, or that its print
9800 length is less than 20.
9802 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9804 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9806 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9808 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9809 We prefer signed integers, even for size calculations.
9811 * emacs.c: Don't assume string length fits in 'int'.
9812 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9813 (main): Don't invoke strlen when not needed.
9815 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9816 (XD_DEBUG_MESSAGE): Don't waste a byte.
9818 * callproc.c (getenv_internal_1, getenv_internal)
9820 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9822 * lread.c (invalid_syntax): Omit length argument.
9823 All uses changed. This doesn't fix a bug, but it simplifies the
9824 code away from its former Hollerith-constant appearance, and it's
9825 one less 'int' to worry about when looking at integer-overflow issues.
9826 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9828 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9829 This didn't break anything, but it didn't help either.
9830 It's confusing to put a bogus integer in a place where the actual
9831 value does not matter.
9832 (LIST_END_P): Remove unused macro and its bogus comment.
9833 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9835 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9836 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9838 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9839 We prefer signed types, and the value cannot exceed the EMACS_INT
9840 range anyway (because otherwise the length would not be representable).
9841 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9842 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9843 This avoids a GCC warning when WIDE_EMACS_INT.
9845 * indent.c (sane_tab_width): New function.
9846 (current_column, scan_for_column, Findent_to, position_indentation)
9847 (compute_motion): Use it. This is just for clarity.
9848 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9850 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9852 * lisp.h (lint_assume): New macro.
9853 * composite.c (composition_gstring_put_cache):
9854 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9856 * editfns.c, insdel.c:
9857 Omit unnecessary forward decls, to simplify future changes.
9859 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9861 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9863 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9864 Use much-faster test for byte-length change.
9865 Don't assume string byte-length fits in 'int'.
9866 Check that character arg fits in 'int'.
9867 (mapcar1): Declare byte as byte, for clarity.
9869 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9871 * fns.c (concat): Catch string overflow earlier.
9872 Do not rely on integer wraparound.
9874 * dispextern.h (struct it.overlay_strings_charpos)
9875 (struct it.selective): Now EMACS_INT, not int.
9876 * xdisp.c (forward_to_next_line_start)
9877 (back_to_previous_visible_line_start)
9878 (reseat_at_next_visible_line_start, next_element_from_buffer):
9879 Don't arbitrarily truncate the value of 'selective' to int.
9881 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9883 * composite.c: Don't truncate sizes to 'int'.
9884 (composition_gstring_p, composition_reseat_it)
9885 (composition_adjust_point): Use EMACS_INT, not int.
9886 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9887 not EMACS_UINT, for indexes.
9889 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9891 * buffer.c: Include <verify.h>.
9892 (struct sortvec.priority, struct sortstr.priority):
9893 Now EMACS_INT, not int.
9894 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9895 (struct sortstr.size, record_overlay_string)
9896 (struct sortstrlist.size, struct sortlist.used):
9897 Don't truncate size to int.
9898 (record_overlay_string): Check for size-calculation overflow.
9899 (init_buffer_once): Check at compile-time, not run-time.
9901 2011-06-22 Jim Meyering <meyering@redhat.com>
9903 Don't leak an XBM-image-sized buffer
9904 * image.c (xbm_load): Free the image buffer after using it.
9906 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9909 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9910 that Sun C diagnosed.
9911 * fns.c (secure_hash): Fix pointer signedness issue.
9912 * intervals.c (static_offset_intervals): New function.
9913 (offset_intervals): Use it.
9915 2011-06-21 Leo Liu <sdl.web@gmail.com>
9918 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9921 * fns.c (secure_hash): Rename from crypto_hash_function and change
9922 the first arg to accept symbols.
9923 (Fsecure_hash): New primitive.
9924 (syms_of_fns): New symbols.
9926 2011-06-20 Deniz Dogan <deniz@dogan.se>
9928 * process.c (Fset_process_buffer): Clarify return value in
9931 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9933 * dispnew.c (add_window_display_history): Use BVAR.
9935 * xdisp.c (debug_method_add): Use BVAR.
9936 (check_window_end, dump_glyph_matrix, dump_glyph)
9937 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9939 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9942 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9943 check till after the cache is created in init_frame_faces.
9945 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9947 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9949 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9951 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9952 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9953 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9955 Improve buffer-overflow checking (Bug#8873).
9956 * fileio.c (Finsert_file_contents):
9957 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9958 Remove the old (too-loose) buffer overflow checks.
9959 They weren't needed, since make_gap checks for buffer overflow.
9960 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9961 The old code merely checked for Emacs fixnum overflow, and relied
9962 on undefined (wraparound) behavior. The new code avoids undefined
9963 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9965 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9966 Tune. Don't use wider integers than needed. Don't use alloca.
9967 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9969 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9971 * insdel.c, lisp.h (buffer_overflow): New function.
9972 (insert_from_buffer_1, replace_range, replace_range_2):
9973 * insdel.c (make_gap_larger):
9974 * editfns.c (Finsert_char):
9975 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9977 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9979 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9981 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9983 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9984 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9986 * fileio.c: Don't assume EMACS_INT fits in off_t.
9987 (emacs_lseek): New static function.
9988 (Finsert_file_contents, Fwrite_region): Use it.
9989 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9991 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9993 * fns.c: Don't overflow int when computing a list length.
9994 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9995 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9996 truncation on 64-bit hosts. Check for QUIT every
9997 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9998 faster and is responsive enough.
9999 (Flength): Report an error instead of overflowing an integer.
10000 (Fsafe_length): Return a float if the value is not representable
10001 as a fixnum. This shouldn't happen except in contrived situations.
10002 (Fnthcdr, Fsort): Don't assume list length fits in int.
10003 (Fcopy_sequence): Don't assume vector length fits in int.
10005 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10006 (header_size, word_size): New constants.
10007 (allocate_vectorlike): Don't check size overflow here.
10008 (allocate_vector): Check it here instead, since this is the only
10009 caller of allocate_vectorlike that could cause overflow.
10010 Check that the new vector's length is representable as a fixnum.
10012 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10013 The previous code was bogus. For example, next_almost_prime (32)
10014 returned 39, which is undesirable as it is a multiple of 3; and
10015 next_almost_prime (24) returned 25, which is a multiple of 5 so
10016 why was the code bothering to check for multiples of 7?
10018 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10020 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10022 Variadic C functions now count arguments with ptrdiff_t.
10023 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10024 Back then I didn't know that the Emacs coding style prefers signed int.
10025 Also, in the meantime I found a few more instances where arguments
10026 were being counted with int, which may truncate counts on 64-bit
10027 machines, or EMACS_INT, which may be unnecessarily wide.
10028 * lisp.h (struct Lisp_Subr.function.aMANY)
10029 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10030 Arg counts are now ptrdiff_t, not size_t.
10031 All variadic functions and their callers changed accordingly.
10032 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10033 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10034 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10035 * callint.c (Fcall_interactively): Check arg count for overflow,
10036 to avoid potential buffer overrun. Use signed char, not 'int',
10037 for 'varies' array, so that we needn't bother to check its size
10038 calculation for overflow.
10039 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10040 * eval.c (apply_lambda):
10041 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10042 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10043 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10045 * callint.c (Fcall_interactively): Don't use index var as event count.
10047 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10048 * mem-limits.h (SIZE): Remove; no longer used.
10050 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10052 Remove unnecessary casts.
10053 * xterm.c (x_term_init):
10054 * xfns.c (x_set_border_pixel):
10055 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10056 These aren't needed now that we assume ANSI C.
10058 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10059 It's more likely to cause problems (due to unsigned overflow)
10062 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10064 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10066 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10068 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10070 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10072 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10074 GLYPH_CODE_FACE returns EMACS_INT, not int.
10075 * dispextern.h (merge_faces):
10076 * xfaces.c (merge_faces):
10077 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10078 Don't assume EMACS_INT fits in int.
10080 * character.h (CHAR_VALID_P): Remove unused parameter.
10081 * fontset.c, lisp.h, xdisp.c: All uses changed.
10083 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10085 * fns.c (concat): Minor tuning based on overflow analysis.
10086 This doesn't fix any bugs. Use int to hold character, instead
10087 of constantly refetching from Emacs object. Use XFASTINT, not
10088 XINT, for value known to be a character. Don't bother comparing
10089 a single byte to 0400, as it's always less.
10091 * floatfns.c (Fexpt):
10092 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10094 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10097 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10099 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10100 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10101 incorrectly succeed when S was a string, because 4294967386 was
10102 truncated before it was used.
10104 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10105 Otherwise, an out-of-range integer could cause undefined behavior
10108 * composite.c: Use int, not EMACS_INT, for characters.
10109 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10110 EMACS_INT, for values that are known to be in character range.
10111 This doesn't fix any bugs but is the usual style inside Emacs and
10112 may generate better code on 32-bit machines.
10114 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10115 This is for reasons similar to the recent CHAR_STRING fix.
10116 * charset.c (Fencode_char): Check that character arg is actually
10117 a character. Pass an int to ENCODE_CHAR.
10118 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10119 wider than 'int', as a compile-time check to prevent future regressions
10122 * character.c (char_string): Remove unnecessary casts.
10124 Make sure a 64-bit char is never passed to CHAR_STRING.
10125 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10126 by silently ignoring the top 32 bits, allowing some values
10127 that were far too large to be valid characters.
10128 * character.h: Include <verify.h>.
10129 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10130 arguments are no wider than unsigned, as a compile-time check
10131 to prevent future regressions in this area.
10133 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10134 (Fsubst_char_in_region):
10136 * xdisp.c (decode_mode_spec_coding):
10137 Adjust to CHAR_STRING's new requirement.
10138 * editfns.c (Finsert_char, Fsubst_char_in_region):
10139 * fns.c (concat): Check that character args are actually
10140 characters. Without this test, these functions did the wrong
10141 thing with wildly out-of-range values on 64-bit hosts.
10143 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10144 These casts should not be needed on 32-bit hosts, either.
10145 * keyboard.c (read_char):
10146 * lread.c (Fload): Remove casts to unsigned.
10148 * lisp.h (UNSIGNED_CMP): New macro.
10149 This fixes comparison bugs on 64-bit hosts.
10150 (ASCII_CHAR_P): Use it.
10151 * casefiddle.c (casify_object):
10152 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10153 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10154 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10155 * dispextern.h (FACE_FROM_ID):
10156 * keyboard.c (read_char): Use UNSIGNED_CMP.
10158 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10159 not to EMACS_INT, to avoid GCC warning.
10161 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10163 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10164 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10165 isn't needed on 32-bit machines.
10167 * buffer.c (Fgenerate_new_buffer_name):
10168 Use EMACS_INT for count, not int.
10169 (advance_to_char_boundary): Return EMACS_INT, not int.
10171 * data.c (Qcompiled_function): Now static.
10173 * window.c (window_body_lines): Now static.
10175 * image.c (gif_load): Rename local to avoid shadowing.
10177 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10178 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10179 * alloc.c (make_save_value): Integer argument is now of type
10180 ptrdiff_t, not int.
10181 (mark_object): Use ptrdiff_t, not int.
10182 * lisp.h (pD): New macro.
10183 * print.c (print_object): Use it.
10185 * alloc.c: Use EMACS_INT, not int, to count objects.
10186 (total_conses, total_markers, total_symbols, total_vector_size)
10187 (total_free_conses, total_free_markers, total_free_symbols)
10188 (total_free_floats, total_floats, total_free_intervals)
10189 (total_intervals, total_strings, total_free_strings):
10190 Now EMACS_INT, not int. All uses changed.
10191 (Fgarbage_collect): Compute overall total using a double, so that
10192 integer overflow is less likely to be a problem. Check for overflow
10193 when converting back to an integer.
10194 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10195 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10196 These were 'int' variables that could overflow on 64-bit hosts;
10197 they were never used, so remove them instead of repairing them.
10198 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10199 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10200 Previously, this ceilinged at INT_MAX, but that doesn't work on
10202 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10204 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10205 (allocate_vectorlike): Check for ptrdiff_t overflow.
10206 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10207 when a (possibly-narrower) signed value would do just as well.
10208 We prefer using signed arithmetic, to avoid comparison confusion.
10210 * alloc.c: Catch some string size overflows that we were missing.
10211 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10212 for convenience in STRING_BYTES_MAX.
10213 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10214 The definition here is exact; the one in lisp.h was approximate.
10215 (allocate_string_data): Check for string overflow. This catches
10216 some instances we weren't catching before. Also, it catches
10217 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10218 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10219 and ptrdiff_t and EMACS_INT are both 64 bits.
10221 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10222 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10223 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10225 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10227 * alloc.c (Fmake_string): Check for out-of-range init.
10229 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10231 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10233 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10235 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10236 xg_get_default_scrollbar_width.
10238 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10239 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10240 (style_changed_cb): Call update_theme_scrollbar_width and call
10241 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10242 all frames (Bug#8505).
10243 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10244 Call gtk_window_set_resizable if HAVE_GTK3.
10245 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10246 and height if HAVE_GTK3 (Bug#8505).
10247 (scroll_bar_width_for_theme): New variable.
10248 (update_theme_scrollbar_width): New function.
10249 (xg_get_default_scrollbar_width): Move code to
10250 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10251 (xg_initialize): Call update_theme_scrollbar_width.
10253 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10255 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10257 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10259 * frame.c (make_frame): Call other_buffer_safely instead of
10262 * window.c (temp_output_buffer_show): Call display_buffer with
10263 second argument Vtemp_buffer_show_specifiers and reset latter
10264 immediately after the call.
10265 (Vtemp_buffer_show_specifiers): New variable.
10266 (auto_window_vscroll_p, next_screen_context_lines)
10267 (Vscroll_preserve_screen_position): Remove leading asterisks from

10274 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10275 (record_buffer): Remove unused local.
10276 * frame.c (other_visible_frames, frame_buffer_list): Now static.

10288 * widgetprv.h (emacsFrameClassRec): Remove decl.
10289 * window.c (delete_deletable_window): Now returns void, since it
10290 wasn't returning anything.
10291 (compare_window_configurations): Remove unused locals.
10292 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

10312 * window.c (delete_deletable_window): Re-add.
10313 (Fset_window_configuration): Rewrite to handle dead buffers and
10314 consequently deletable windows.
10315 (window_tree, Fwindow_tree): Remove. Supply functionality in
10317 (compare_window_configurations): Simplify code.

10450 Remove static from declaration of Qdelete_window, it's
10451 temporarily needed by Fbury_buffer.
10452 (replace_window): Don't assign orig_top_line and
10454 (Fdelete_window, delete_window): Remove. Window deletion is

10456 (window_loop): Remove DELETE_OTHER_WINDOWS case.
10457 Replace Fdelete_window calls with calls to Qdelete_window.
10458 (Fdelete_other_windows): Remove. Deleting other windows is

10863 * gnutls.c: Use Emacs's memory allocators.
10864 Without this change, the gnutls library would invoke malloc etc.
10865 directly, which causes problems on non-SYNC_INPUT hosts, and which
10866 runs afoul of improving memory_full behavior. (Bug#8761)
10867 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10868 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10869 xfree instead of the default malloc, realloc, free.
10870 (Fgnutls_boot): No need to check for memory allocation failure,
10871 since xmalloc does that for us.

10902 Check for integer overflow with large hash tables.
10903 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10904 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10905 (SXHASH_REDUCE): New macro.

10907 Use it instead of discarding useful hash info with large hash values.
10908 (sxhash_float): New function.
10909 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10910 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10911 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10912 Rewrite to use FIXNUM_BITS, as this simplifies things.
10913 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10914 Adjust signatures to match updated version of code.
10915 (consing_since_gc): Now EMACS_INT, since a single hash table can
10916 use more than INT_MAX bytes.
10918 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
10920 Make it possible to build with GCC-4.6+ -O2 -flto.
10922 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
10924 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
10926 * minibuf.c (get_minibuffer, read_minibuf_unwind):
10927 Call minibuffer-inactive-mode.
10929 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
10931 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
10932 Update dependencies.
10934 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10936 * data.c (init_data): Remove code for UTS, this system is not
10939 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10941 Don't force ./temacs to start in terminal mode.
10943 * frame.c (make_initial_frame): Initialize faces in all cases, not
10944 only when CANNOT_DUMP is defined.
10945 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10947 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10949 * dispnew.c (add_window_display_history): Use const for the string
10950 pointer. Remove declaration, not needed.
10952 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10954 Use 'inline', not 'INLINE'.
10955 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10956 * alloc.c, fontset.c (INLINE): Remove.
10957 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10958 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10959 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10960 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10961 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10963 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10965 Make it possible to run ./temacs.
10967 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10968 syms_of_callproc does the same thing. Remove test for
10969 "initialized", do it in the caller.
10970 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10972 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10974 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10975 (read_minibuf): Use get_minibuffer.
10976 (syms_of_minibuf): Use DEFSYM.
10977 (Qmetadata): New var.
10978 * data.c (Qbuffer): Don't make it static.
10979 (syms_of_data): Use DEFSYM.
10981 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10983 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10984 (CCL_CODE_MIN): New macro.
10986 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10988 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10990 * eval.c (Qdebug): Now static.
10991 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10992 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10993 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10995 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10997 * image.c: Various fixes to ImageMagick code comments.
10998 (Fimagemagick_types): Doc fix.
11000 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11002 Minor fixes prompted by GCC 4.6.0 warnings.
11004 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11006 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11007 (x_clipboard_manager_save_all): Move extern decl to ...
11008 * xterm.h: ... here, so that it can be checked for consistency.
11010 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11012 * xselect.c (x_clipboard_manager_save_frame)
11013 (x_clipboard_manager_save_all): New functions.
11014 (Fx_clipboard_manager_save): Lisp function deleted.
11016 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11017 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11019 * xterm.h: Update prototype.
11021 2011-05-28 William Xu <william.xwl@gmail.com>
11023 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11024 exiting (Bug#8239).
11026 2011-05-28 Jim Meyering <meyering@redhat.com>
11028 Avoid a sign-extension bug in crypto_hash_function.
11029 * fns.c (to_uchar): Define.
11030 (crypto_hash_function): Use it to convert some newly-signed
11031 variables to unsigned, to avoid sign-extension bugs. For example,
11032 without this change, (md5 "truc") would evaluate to
11033 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11034 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11035 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11037 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11039 Integer overflow fixes.
11041 * dbusbind.c: Serial number integer overflow fixes.
11042 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11043 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11044 to hold a serial number that is too large for a fixnum.
11045 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11046 Check for serial numbers out of range. Decode any serial number
11047 that was so large that it became a float. (Bug#8722)
11049 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11050 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11051 Use XFASTINT rather than XUINT when numbers are nonnegative.
11052 (xd_append_arg, Fdbus_method_return_internal):
11053 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11054 arguments, check that Lisp number is nonnegative, rather than
11055 silently wrapping negative numbers around. (Bug#8722)
11056 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11059 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11061 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11063 ccl: Add integer overflow checks.
11064 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11065 (IN_INT_RANGE): New macros.
11066 (ccl_driver): Use them to check for integer overflow when
11067 decoding a CCL program. Many of the new checks are whether XINT (x)
11068 fits in int; it doesn't always, on 64-bit hosts. The new version
11069 doesn't catch all possible integer overflows, but it's an
11070 improvement. (Bug#8719)
11072 * alloc.c (make_event_array): Use XINT, not XUINT.
11073 There's no need for unsigned here.
11075 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11076 This follows up to the 2011-05-06 change that substituted uintptr_t
11077 for EMACS_INT. This case wasn't caught back then.
11079 Rework Fformat to avoid integer overflow issues.
11080 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11081 now (part of C89). Include <verify.h>.
11082 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11083 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11084 (Fformat): Avoid the prepass trying to compute sizes; it was only
11085 approximate and thus did not catch overflow reliably. Instead, walk
11086 through the format just once, formatting and computing sizes as we go,
11087 checking for integer overflow at every step, and allocating a larger
11088 buffer as needed. Keep track separately whether the format is
11089 multibyte. Keep only the most-recently calculated precision, rather
11090 than them all. Record whether each argument has been converted to
11091 string. Use EMACS_INT, not int, for byte and char and arg counts.
11092 Support field widths and precisions larger than INT_MAX. Avoid
11093 sprintf's undefined behavior with conversion specifications such as %#d
11094 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11095 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11096 formatting out-of-range floating point numbers with int
11097 formats. (Bug#8668)
11099 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11101 * data.c: Avoid integer truncation in expressions involving floats.
11102 * data.c: Include <intprops.h>.
11103 (arith_driver): When there's an integer overflow in an expression
11104 involving floating point, convert the integers to floating point
11105 so that the resulting value does not suffer from catastrophic
11106 integer truncation. For example, on a 64-bit host (* 4
11107 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11108 Do not rely on undefined behavior after integer overflow.
11110 merge count_size_as_multibyte, parse_str_to_multibyte
11111 * character.c, character.h (count_size_as_multibyte):
11112 Rename from parse_str_to_multibyte; all uses changed.
11113 Check for integer overflow.
11114 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11115 since it's now a duplicate of the other. This is more of
11116 a character than a buffer op, so better that it's in character.c.
11117 * fns.c, print.c: Adjust to above changes.
11119 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11121 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11123 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11125 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11126 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11127 (x_clipboard_manager_save): Now static.
11128 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11130 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11131 (crypto_hash_function): Now static.
11132 Fix pointer signedness problems. Avoid unnecessary initializations.
11134 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11136 * termhooks.h (Vselection_alist): Make it terminal-local.
11138 * terminal.c (create_terminal): Initialize it.
11140 * xselect.c: Support for clipboard managers.
11141 (Vselection_alist): Move to termhooks.h as terminal-local var.
11142 (LOCAL_SELECTION): New macro.
11143 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11144 (symbol_to_x_atom): Remove gratuitous arg.
11145 (x_handle_selection_request, lisp_data_to_selection_data)
11146 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11147 (x_own_selection, x_get_local_selection, x_convert_selection):
11148 New arg, specifying work frame. Use terminal-local Vselection_alist.
11149 (some_frame_on_display): Delete unused function.
11150 (Fx_own_selection_internal, Fx_get_selection_internal)
11151 (Fx_disown_selection_internal, Fx_selection_owner_p)
11152 (Fx_selection_exists_p): New optional frame arg.
11153 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11154 (x_handle_selection_clear): Don't treat other terminals with the
11155 same keyboard specially. Use the terminal-local Vselection_alist.
11156 (x_clear_frame_selections): Use Frun_hook_with_args.
11158 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11160 * xterm.h: Add support for those atoms.
11162 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11164 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11165 (converted_selections, conversion_fail_tag): New global variables.
11166 (x_selection_request_lisp_error): Free the above.
11167 (x_get_local_selection): Remove unnecessary code.
11168 (x_reply_selection_request): Args changed; handle arbitrary array
11169 of converted selections stored in converted_selections.
11170 Separate the XChangeProperty and SelectionNotify steps.
11171 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11172 (x_convert_selection): New function.
11173 (x_handle_selection_event): Simplify.
11174 (x_get_foreign_selection): Don't ignore incoming requests while
11175 waiting for an answer; this will fail when we implement
11176 SAVE_TARGETS, and seems unnecessary anyway.
11177 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11178 (Vx_sent_selection_functions): Doc fix.
11180 2011-05-26 Leo Liu <sdl.web@gmail.com>
11182 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11184 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11186 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11188 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11189 for fringe update if it has periodic bitmap.
11190 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11191 and fringe_bitmap_periodic_p.
11193 * fringe.c (get_fringe_bitmap_data): New function.
11194 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11195 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11196 row. Mark glyph row for fringe update if periodicity changed.
11198 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11199 for fringe update unless it has periodic bitmap.
11201 2011-05-25 Kenichi Handa <handa@m17n.org>
11203 * xdisp.c (get_next_display_element): Set correct it->face_id for
11204 a static composition.
11206 2011-05-24 Leo Liu <sdl.web@gmail.com>
11209 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11211 * fns.c (crypto_hash_function, Fsha1): New function.
11212 (Fmd5): Use crypto_hash_function.
11213 (syms_of_fns): Add Ssha1.
11215 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11217 * gnutls.c: Remove unused macros.
11218 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11219 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11220 Remove macros that are defined and never used.
11221 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11223 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11225 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11226 (Fx_get_selection_internal): Minor cleanup.
11227 (Fx_own_selection_internal): Rename arguments for consistency with
11230 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11232 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11234 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11236 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11238 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11240 * dispnew.c (scrolling_window): Don't exclude the case that the
11241 last enabled row in the desired matrix touches the bottom boundary.
11243 2011-05-21 Glenn Morris <rgm@gnu.org>
11245 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11246 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11247 and add some more files.
11249 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11251 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11252 report_file_error introduced by the change from 2011-05-07.
11254 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11256 * systime.h (Time): Define only if emacs is defined.
11257 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11258 where the include path doesn't have X11/X.h by default. See
11259 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11261 2011-05-20 Kenichi Handa <handa@m17n.org>
11263 * composite.c (find_automatic_composition): Fix previous change.
11265 2011-05-20 Glenn Morris <rgm@gnu.org>
11267 * lisp.mk: New file, split from Makefile.in.
11268 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11269 (shortlisp): Remove.
11270 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11272 2011-05-19 Glenn Morris <rgm@gnu.org>
11274 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11275 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11276 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11277 (lisp): Set the order to that of loadup.el.
11278 (shortlisp): Make it a copy of $lisp.
11279 (SOME_MACHINE_LISP): Remove.
11280 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11281 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11283 2011-05-18 Kenichi Handa <handa@m17n.org>
11285 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11286 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11287 (find_automatic_composition): Mostly rewrite for efficiency.
11289 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11291 * makefile.w32-in: Update dependencies.
11293 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11295 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11296 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11298 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11300 Fix some integer overflow issues, such as string length overflow.
11302 * insdel.c (count_size_as_multibyte): Check for string overflow.
11304 * character.c (lisp_string_width): Check for string overflow.
11305 Use EMACS_INT, not int, for string indexes and lengths; in
11306 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11307 the resulting string length overflows an EMACS_INT; instead,
11308 report a string overflow if no precision given. When checking for
11309 precision exhaustion, use a check that cannot possibly have
11310 integer overflow. (Bug#8675)
11311 * character.h (lisp_string_width): Adjust to new signature.
11313 * alloc.c (string_overflow): New function.
11314 (Fmake_string): Use it. This doesn't change behavior, but saves
11315 a few bytes and will simplify future changes.
11316 * character.c (string_escape_byte8): Likewise.
11317 * lisp.h (string_overflow): New decl.
11319 Fixups, following up to the user-interface timestamp change.
11320 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11321 for UI timestamps, instead of unsigned long.
11322 * msdos.c (mouse_get_pos): Likewise.
11323 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11324 * w32gui.h (Time): Define by including "systime.h" rather than by
11325 declaring it ourselves. (Bug#8664)
11327 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11328 * image.c (clear_image_cache): Likewise.
11330 * term.c (term_mouse_position): Don't assume time_t wraparound.
11332 Be more systematic about user-interface timestamps.
11333 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11334 and sometimes 'EMACS_UINT', to represent these timestamps.
11335 This change causes it to use 'Time' uniformly, as that's what X uses.
11336 This makes the code easier to follow, and makes it easier to catch
11337 integer overflow bugs such as Bug#8664.
11338 * frame.c (Fmouse_position, Fmouse_pixel_position):
11339 Use Time, not unsigned long, for user-interface timestamps.
11340 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11341 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11342 * keyboard.h (last_event_timestamp): Likewise.
11343 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11344 * menu.h (xmenu_show): Likewise.
11345 * term.c (term_mouse_position): Likewise.
11346 * termhooks.h (struct input_event.timestamp): Likewise.
11347 (struct terminal.mouse_position_hook): Likewise.
11348 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11349 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11350 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11351 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11352 what it was before.
11353 * menu.h, termhooks.h: Include "systime.h", for Time.
11355 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11356 Don't assume that the difference between two unsigned long values
11357 can fit into an integer. At this point, we know button_down_time
11358 <= event->timestamp, so the difference must be nonnegative, so
11359 there's no need to cast the result if double-click-time is
11360 nonnegative, as it should be; check that it's nonnegative, just in
11361 case. This bug is triggered when events are more than 2**31 ms
11362 apart (about 25 days). (Bug#8664)
11364 * xselect.c (last_event_timestamp): Remove duplicate decl.
11365 (x_own_selection): Remove needless cast to unsigned long.
11367 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11368 that always fit in int. Use a sentinel instead of a counter, to
11369 avoid a temp and to allay GCC's concerns about possible int overflow.
11370 * frame.h (struct frame): Use int for menu_bar_items_used
11371 instead of EMACS_INT, since it always fits in int.
11373 * menu.c (grow_menu_items): Check for int overflow.
11375 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11377 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11378 Before, the code was not consistent. These values cannot exceed
11379 2**31 - 1 so there's no need to make them unsigned.
11380 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11381 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11382 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11384 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11386 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11387 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11388 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11389 presumably because the widths might not match.
11391 * window.c (size_window): Avoid needless test at loop start.
11393 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11395 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11397 2011-05-12 Drew Adams <drew.adams@oracle.com>
11399 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11401 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11403 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11404 `width' to `bar_area_x' and `bar_area_width', respectively.
11405 (x_scroll_run): Take account of fringe background extension.
11407 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11408 Rename local vars `left' and `width' to `bar_area_x' and
11409 `bar_area_width', respectively.
11410 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11411 background extension.
11413 2011-05-10 Jim Meyering <meyering@redhat.com>
11415 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11417 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11419 * image.c (Finit_image_library): Return t for built-in image types,
11420 like pbm and xbm. (Bug#8640)
11422 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11424 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11426 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11428 * w32console.c (Fset_screen_color): Doc fix.
11429 (Fget_screen_color): New function.
11430 (syms_of_ntterm): Defsubr it.
11432 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11433 unlink the temporary file if Fcall_process didn't create it in the
11435 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11436 child process will be redirected to a file specified with `:file'.
11437 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11438 cue to call_process_cleanup not to close that handle.
11440 2011-05-07 Ben Key <bkey76@gmail.com>
11442 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11443 one of two shell specific rules, either bootstrap-temacs-CMD or
11444 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11445 to the previous implementation of the bootstrap-temacs rule.
11446 The bootstrap-temacs-CMD rule is similar to the previous
11447 implementation of the bootstrap-temacs rule except that it
11448 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11451 These changes, along with some changes to nt/configure.bat,
11452 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11453 earlier fix to add support for --cflags and --ldflags options
11454 that include quotes so that it works whether make uses cmd or
11457 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11459 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11460 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11462 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11463 a string. Handle both cases.
11464 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11465 (Fdbus_register_method): Use Qinvalid_function.
11467 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11469 * makefile.w32-in: Update dependencies.
11470 (LISP_H): Add inttypes.h and stdin.h.
11471 (PROCESS_H): Add unistd.h.
11473 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11475 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11476 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11478 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11480 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11482 * term.c (vfatal): Remove stray call to va_end.
11483 It's not needed and the C Standard doesn't allow it here anyway.
11485 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11486 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11488 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11491 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11493 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11495 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11497 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11499 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11501 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11502 * charset.c (Fdefine_charset_internal): Don't initialize
11503 charset.code_space[15]. The value was garbage, on hosts with
11504 32-bit int (Bug#8600).
11506 * lread.c (read_integer): Be more consistent with string-to-number.
11507 Use string_to_number to do the actual conversion; this avoids
11508 rounding errors and fixes some other screwups. Without this fix,
11509 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11510 (digit_to_number): Move earlier, for benefit of read_integer.
11511 Return -1 if the digit is out of range for the base, -2 if it is
11512 not a digit in any supported base. (Bug#8602)
11514 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11516 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11517 to match comment at start of function. This also removes a
11518 GCC warning about overflow in a 32+64-bit port.
11520 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11522 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11523 Reported by Stefan Monnier in
11524 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11525 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11526 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11528 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11529 (EMACS_UINTPTR): Likewise, with uintptr_t.
11531 * lisp.h: Prefer 64-bit EMACS_INT if available.
11532 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11533 on 32-bit hosts that have 64-bit int, so that they can access
11535 However, temporarily disable this change unless the temporary
11536 symbol WIDE_EMACS_INT is defined.
11538 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11540 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11541 This removes an assumption that EMACS_INT and long are the same
11542 width as pointers. The assumption is true for Emacs porting targets
11543 now, but we want to make other targets possible.
11544 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11545 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11546 In the rest of the code, change types of integers that hold casted
11547 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11548 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11549 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11550 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11551 No need to cast type when ORing.
11552 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11553 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11554 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11555 assume EMACS_INT is the same width as char *.
11556 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11557 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11558 Remove no-longer-needed casts.
11559 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11560 (xg_tool_bar_help_callback, xg_make_tool_item):
11561 Use EMACS_INTPTR to hold an integer
11562 that will be cast to void *; this can avoid a GCC warning
11563 if EMACS_INT is not the same width as void *.
11564 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11565 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11566 (current_message_1, set_message_1):
11567 Use a local to convert to proper width without a cast.
11568 * xmenu.c (dialog_selection_callback): Likewise.
11570 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11571 Also, don't assume VALBITS / RAND_BITS is less than 5,
11572 and don't rely on undefined behavior when shifting a 1 left into
11574 * lisp.h (get_random): Change signature to match.
11576 * lread.c (hash_string): Use size_t, not int, for hash computation.
11577 Normally we prefer signed values; but hashing is special, because
11578 it's better to use unsigned division on hash table sizes so that
11579 the remainder is nonnegative. Also, size_t is the natural width
11580 for hashing into memory. The previous code used 'int', which doesn't
11581 retain enough info to hash well into very large tables.
11582 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11584 * dbusbind.c: Don't possibly lose pointer info when converting.
11585 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11586 Use XPNTR rather than XHASH, so that the high-order bits of
11587 the pointer aren't lost when converting through void *.
11589 * eval.c (Fautoload): Don't double-shift a pointer.
11591 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11593 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11595 * gnutls.c (DEF_GNUTLS_FN):
11596 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11598 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11600 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11603 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11605 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11606 New version that can reserve upto 2GB of heap space.
11608 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11610 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11612 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11614 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11615 `gnutls_certificate_set_x509_key_file'.
11617 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11619 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11620 Update dependencies.
11622 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11624 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11625 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11626 Remove unused parameter `fildes'.
11627 * process.c (read_process_output, send_process): Don't pass it.
11629 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11631 Fix previous change: the library cache is defined in w32.c.
11632 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11633 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11635 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11637 Implement dynamic loading of GnuTLS on Windows.
11639 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11640 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11641 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11644 * gnutls.c (Qgnutls_dll): Define.
11645 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11646 (gnutls_*): Declare function pointers.
11647 (init_gnutls_functions): New function to initialize function pointers.
11648 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11649 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11650 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11651 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11652 (emacs_gnutls_write, emacs_gnutls_read)
11653 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11654 (Fgnutls_available_p): New function.
11655 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11656 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11657 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11659 * image.c: Include w32.h.
11660 (Vimage_type_cache): Delete.
11661 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11662 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11663 (w32_delayed_load): Move to w32.c.
11665 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11667 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11668 (w32_delayed_load): Move from image.c. When loading a library, record
11669 its filename in the :loaded-from property of the library id.
11670 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11671 Initialize and staticpro them.
11672 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11674 * process.c: Include lisp.h before w32.h, not after.
11675 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11676 instead of gnutls_record_check_pending.
11678 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11680 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11682 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11683 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11686 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11688 * xterm.c (x_set_frame_alpha): Do not set property on anything
11689 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11691 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11693 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11695 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11697 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11698 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11704 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
11705 (Qgnutls_bootprop_callbacks_verify): Make static.
11707 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11709 * callproc.c: Indentation fixup.
11711 * sysdep.c (wait_for_termination_1): Make static.
11712 (wait_for_termination, interruptible_wait_for_termination):
11713 Move after wait_for_termination_1.
11715 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11717 * sysdep.c (interruptible_wait_for_termination): New function
11718 which is like wait_for_termination, but allows keyboard
11721 * callproc.c (Fcall_process): Add (:file "file") as an option for
11723 (Fcall_process_region): Ditto.
11725 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11727 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11728 rather than `XVECTOR (FOO)->size'.
11730 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11731 inttypes.h, as a gnulib replacement is used if it not available in
11734 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11736 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11737 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11738 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11740 * coding.c (coding_alloc_by_realloc): Error out if destination
11741 will grow beyond MOST_POSITIVE_FIXNUM.
11742 (decode_coding_emacs_mule): Abort if there isn't enough place in
11743 charbuf for the composition carryover bytes. Reserve an extra
11744 space for up to 2 characters produced in a loop.
11745 (decode_coding_iso_2022): Abort if there isn't enough place in
11746 charbuf for the composition carryover bytes.

11751 aborting when %lld or %lll format is passed.
11752 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11753 %llo or %llx format is passed. (Bug#8545)
11755 * window.c (window_scroll_line_based): Use a marker instead of
11756 simple variables to record original value of point. (Bug#7952)
11758 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11759 produced by %s or %c overflows available buffer space. (Bug#8545)
11761 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11763 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11764 (SIZE_MAX): Move defn after all includes, as they might #define it.
11766 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11768 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11770 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11772 * keyboard.c (Qdelayed_warnings_hook): Define.

11774 if Vdelayed_warnings_list is non-nil.
11775 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11776 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11778 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11780 * doprnt.c (doprnt): Don't return value smaller than the buffer
11781 size if the message was truncated. (Bug#8545).
11783 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11785 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11786 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11788 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11790 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11792 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11794 * makefile.w32-in: Update dependencies.
11796 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11798 Improve `doprnt' and its usage. (Bug#8545)
11799 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11800 `format_end'. Remove support for %l as a conversion specifier.
11801 Don't use xrealloc. Improve diagnostics when the %l size modifier
11802 is used. Update the commentary.
11804 * eval.c (verror): Simplify calculation of size_t.
11806 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11809 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11811 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11814 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11816 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11817 This makes this file independent of the recent pseudovector change.
11819 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11821 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11823 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11824 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11825 Remove unused local.
11826 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11828 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11829 GCC 4.6.0 optimizes based on type-based alias analysis.
11830 For example, if b is of type struct buffer * and v of type struct
11831 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11832 != &v->size, and therefore "v->size = 1; b->size = 2; return
11833 v->size;" must therefore return 1. This assumption is incorrect
11834 for Emacs, since it type-puns struct Lisp_Vector * with many other
11835 types. To fix this problem, this patch adds a new type struct
11836 vectorlike_header that documents the constraints on layout of vectors
11837 and pseudovectors, and helps optimizing compilers not get fooled
11838 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11839 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11840 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11842 (XSETPVECTYPE): Rewrite in terms of new macro.
11843 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11844 This is a bit clearer, and further avoids the possibility of
11845 undesirable aliasing.
11846 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11847 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11848 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11849 since Lisp_Subr is a special case (no "next" field).
11850 (ASIZE): Now uses header.size rather than size.
11851 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11852 to avoid the hassle of writing XVECTOR (foo)->header.size.
11853 (struct vectorlike_header): New type.
11854 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11855 object, to help avoid aliasing.
11856 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11857 (SUBRP): Likewise, since Lisp_Subr is a special case.
11858 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11859 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11860 (struct Lisp_Hash_Table): Combine first two members into a single
11861 struct vectorlike_header member. All uses of "size" and "next" members
11862 changed to be "header.size" and "header.next".
11863 * buffer.h (struct buffer): Likewise.
11864 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11865 * frame.h (struct frame): Likewise.
11866 * process.h (struct Lisp_Process): Likewise.
11867 * termhooks.h (struct terminal): Likewise.
11868 * window.c (struct save_window_data, struct saved_window): Likewise.
11869 * window.h (struct window): Likewise.
11870 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11871 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11872 * buffer.c (init_buffer_once): Likewise.
11873 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11875 * process.c (Fformat_network_address): Use local var for size,
11878 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11880 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11881 * data.c (atof): Remove decl; no longer used or needed.
11882 (digit_to_number): Move to lread.c.
11883 (Fstring_to_number): Use new string_to_number function, to be
11884 consistent with how the Lisp reader treats infinities and NaNs.
11885 Do not assume that floating-point numbers represent EMACS_INT
11886 without losing information; this is not true on most 64-bit hosts.
11887 Avoid double-rounding errors, by insisting on integers when
11888 parsing non-base-10 numbers, as the documentation specifies.
11889 * lisp.h (string_to_number): New decl, replacing ...
11890 (isfloat_string): Remove.
11891 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11892 (read1): Do not accept +. and -. as integers; this
11893 appears to have been a coding error. Similarly, do not accept
11894 strings like +-1e0 as floating point numbers. Do not report
11895 overflow for integer overflows unless the base is not 10 which
11896 means we have no simple and reliable way to continue.
11897 Break out the floating-point parsing into a new
11898 function string_to_number, so that Fstring_to_number parses
11899 floating point numbers consistently with the Lisp reader.
11900 (digit_to_number): Move here from data.c. Make it static inline.
11901 (E_CHAR, EXP_INT): Remove, replacing with ...
11902 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11903 (string_to_number): New function, replacing isfloat_string.
11904 This function checks for valid syntax and produces the resulting
11905 Lisp float number too. Rework it so that string-to-number
11906 no longer mishandles examples like "1.0e+". Use strtoumax,
11907 so that overflow for non-base-10 numbers is reported only when
11908 there's no portable and simple way to convert to floating point.
11910 * textprop.c (set_text_properties_1): Rewrite for clarity,
11911 and to avoid GCC warning about integer overflow.
11913 * intervals.h (struct interval): Use EMACS_INT for members
11914 where EMACS_UINT might cause problems. See
11915 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11916 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11917 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11919 (offset_intervals): Tell GCC not to worry about length overflow
11920 when negating a negative length.
11922 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11923 (overrun_check_free): Likewise.
11925 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11926 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11929 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11930 (gnutls_make_error): Rename local to avoid shadowing.
11931 (gnutls_emacs_global_deinit): ifdef out; not used.
11932 (Fgnutls_boot): Use const for pointer to readonly storage.
11933 Comment out unused local. Fix pointer signedness problems.
11935 * lread.c (openp): Don't stuff size_t into an 'int'.
11936 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11937 about possible signed overflow.
11939 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11940 (GDK_KEY_g): Don't define if already defined.
11941 (xg_prepare_tooltip): Avoid pointer signedness problem.
11942 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11944 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11945 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11947 * xfns.c (Fx_window_property): Simplify a bit,
11948 to make a bit faster and to avoid GCC 4.6.0 warning.
11949 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11951 * fns.c (internal_equal): Don't assume size_t fits in int.
11953 * alloc.c (compact_small_strings): Tighten assertion a little.
11955 Replace pEd with more-general pI, and fix some printf arg casts.
11956 * lisp.h (pI): New macro, generalizing old pEd macro to other
11957 conversion specifiers. For example, use "...%"pI"d..." rather
11958 than "...%"pEd"...".
11959 (pEd): Remove. All uses replaced with similar uses of pI.
11960 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11961 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11962 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11963 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11964 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11965 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11966 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11968 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11969 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11970 * print.c (safe_debug_print, print_object): Likewise.
11971 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11973 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11974 avoiding the 0 flag, which is not portable.
11975 * process.c (Fmake_network_process): Use pI to avoid cast.
11976 * region-cache.c (pp_cache): Likewise.
11977 * xdisp.c (decode_mode_spec): Likewise.
11978 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11979 behavior on 64-bit hosts with printf arg.
11980 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11981 (x_stop_queuing_selection_requests): Likewise.
11982 (x_get_window_property): Don't truncate byte count to an 'int'
11985 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11986 here, since it parses constructs like leading '-' and spaces,
11987 which are not wanted; and it overflows with large numbers.
11988 Instead, simply match F[0-9]+, which is what is wanted anyway.
11990 * alloc.c: Remove unportable assumptions about struct layout.
11991 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11992 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11993 (allocate_vectorlike, make_pure_vector): Use the new macros,
11994 plus offsetof, to remove unportable assumptions about struct layout.
11995 These assumptions hold on all porting targets that I know of, but
11996 they are not guaranteed, they're easy to remove, and removing them
11997 makes further changes easier.
11999 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12000 This doesn't fix a bug but makes the code clearer.
12001 (string_overrun_cookie): Now const. Use initializers that
12002 don't formally overflow signed char, to avoid warnings.
12003 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12004 can cause Emacs to crash when string overrun checking is enabled.
12005 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12006 multiple of sizeof (EMACS_INT); it need not be, if
12007 alignof(EMACS_INT) < sizeof (EMACS_INT).
12008 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12010 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12017 supposed to be handshaking. (Bug#8556)
12018 Reported by Paul Eggert <eggert@cs.ucla.edu>.

12037 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12039 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12040 "cast to pointer from integer of different size".
12042 Improve doprnt and its use in verror. (Bug#8545)
12043 * doprnt.c (doprnt): Document the set of format control sequences
12044 supported by the function. Use SAFE_ALLOCA instead of always
12047 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12048 is one byte too soon. Don't use xrealloc; instead xfree and
12051 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12053 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12056 * gnutls.c: Renamed global_initialized to
12057 gnutls_global_initialized. Added internals for the
12058 :verify-hostname-error, :verify-error, and :verify-flags
12059 parameters of `gnutls-boot' and documented those parameters in the
12060 docstring. Start callback support.
12061 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12062 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12063 on error. Return error code.
12064 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12065 (emacs_gnutls_read): Likewise.
12066 (Fgnutls_boot): Return handshake error code.

12130 <char-direction-table>: Deleted.
12132 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12134 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12135 * doprnt.c: Include limits.h.
12136 (SIZE_MAX): New macro.
12137 (doprnt): Return a size_t value. 2nd arg is now size_t.
12138 Many local variables are now size_t instead of int or unsigned.
12139 Improve overflow protection. Support `l' modifier for integer
12140 conversions. Support %l conversion. Don't assume an EMACS_INT
12141 argument for integer conversions and for %c.
12143 * lisp.h (doprnt): Restore prototype.
12145 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12146 $(SRC)/character.h.
12148 * Makefile.in (base_obj): Add back doprnt.o.
12150 * deps.mk (doprnt.o): Add back prerequisites.
12151 (callint.o): Depend on character.h.
12153 * eval.c (internal_lisp_condition_case): Include the handler
12154 representation in the error message.
12155 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12156 when breaking from the loop.

12160 * callint.c (Fcall_interactively): When displaying error message
12161 about invalid control letter, pass the character's codepoint, not
12162 a pointer to its multibyte form. Improve display of the character
12163 in octal and display also its hex code.
12165 * character.c (char_string): Use %x to display the (unsigned)
12166 codepoint of an invalid character, to avoid displaying a bogus
12169 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12170 `error', not SYMBOL_NAME itself.
12172 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12173 character arguments to `error'.
12175 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12176 to `error' in error message about FINAL_CHAR argument. Make sure
12177 FINAL_CHAR is a character, and use %c when it is passed as
12178 argument to `error'.

12244 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12245 by pacifying GCC about it. Maybe it's time to retire it?

12248 * dispextern.h (struct redisplay_interface): Rename param

12367 * nsfont.m: Fixed bugs in ns_get_family and
12368 ns_descriptor_to_entity that were caused by using free to
12369 deallocate memory blocks that were allocated by xmalloc (via
12370 xstrdup). This caused Emacs to crash when compiled with
12371 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12372 --enable-checking=xmallocoverrun). xfree is now used to
12373 deallocate these memory blocks.

12389 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
12390 (emacs_read, emacs_write): Use it.
12391 * process.c (send_process): Adjust to the new signatures of
12392 emacs_write and emacs_gnutls_write. Do not attempt to store

12722 * lisp.h: Remove these decls.
12724 * buffer.c (buffer_count): Remove unused var.
12726 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

12728 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12729 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12730 exported only to the debugger.
12732 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12733 * atimer.h (run_all_atimers): Remove; not exported.
12735 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12736 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12737 was inaccessible from Lisp.
12738 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12739 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12741 alloc.c: Import and export fewer symbols, and remove unused items.
12742 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12744 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12745 it's not optimized away by whole-program optimization.
12746 (message_enable_multibyte, free_misc): Remove.
12747 (catchlist, handlerlist, mark_backtrace):
12748 Declare only if BYTE_MARK_STACK.

12757 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12758 (mark_backtrace): Define only if BYTE_MARK_STACK.
12759 * xdisp.c (message_enable_multibyte): Now static.
12761 Declare Lisp_Object Q* variables to be 'static' if not exported.
12762 This makes it easier for human readers (and static analyzers)
12763 to see whether these variables are used from other modules.
12764 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12765 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12766 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

12774 Remove decls of unexported vars.
12775 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12777 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12779 Make Emacs functions such as Fatom 'static' by default.
12780 This makes it easier for human readers (and static analyzers)
12781 to see whether these functions can be called from other modules.
12782 DEFUN now defines a static function. To make the function external
12783 so that it can be used in other C modules, use the new macro DEFUE.
12784 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12785 (Finit_image_library):
12786 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

12788 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12789 Remove decls, since these functions are now static.
12790 (Funintern, Fget_internal_run_time): New decls, since these functions
12791 were already external.
12793 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

12800 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12801 Mark functions with DEFUE instead of DEFUN,
12802 if they are used in other modules.
12803 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12804 decls for now-static functions.
12805 * buffer.h (Fdelete_overlay): Remove decl.

12815 * image.c (Finit_image_library): New forward static decl.
12816 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12817 * intervals.h (Fprevious_property_change):
12818 (Fremove_list_of_text_properties): Remove decls.
12819 * keyboard.c (Fthis_command_keys): Remove decl.
12820 (Fcommand_execute): New forward static decl.

12836 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12838 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12841 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12843 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12844 when at ZV. (Bug#8487)
12846 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12848 * charset.c (Fclear_charset_maps): Use xfree instead of free.

12851 * sound.c (sound_cleanup, alsa_close): Likewise.
12852 * termcap.c (tgetent): Likewise.
12853 * xfns.c (x_default_font_parameter): Likewise.
12854 * xsettings.c (read_and_apply_settings): Likewise.
12856 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12857 (overrun_check_free): Protoize.
12859 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12861 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12862 since callers should never pass a negative size.
12863 Change the signature to match that of plain 'read' and 'write'; see
12864 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12865 * lisp.h: Update prototypes of emacs_write and emacs_read.
12867 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12869 * xdisp.c (redisplay_window): Don't try to determine the character
12870 position of the scroll margin if the window start point w->startp
12871 is outside the buffer's accessible region. (Bug#8468)
12873 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12875 Fix write-region and its subroutines for buffers > 2GB.
12876 * fileio.c (a_write, e_write): Modify declaration of arguments and
12877 local variables to support buffers larger than 2GB.
12878 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12880 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12881 argument, local variables, and return value.
12883 * lisp.h: Update prototypes of emacs_write and emacs_read.
12885 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12887 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12889 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12891 Fix more problems found by GCC 4.6.0's static checks.
12893 * xdisp.c (vmessage): Use a better test for character truncation.
12895 * charset.c (load_charset_map): <, not <=, for optimization,
12896 and to avoid potential problems with integer overflow.
12897 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12898 * casetab.c (set_identity, shuffle): Likewise.
12899 * editfns.c (Fformat): Likewise.
12900 * syntax.c (skip_chars): Likewise.
12902 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12903 This also lets GCC 4.6.0 generate slightly better loop code.
12905 * callint.c (Fcall_interactively): <, not <=, for optimization.
12906 (Fcall_interactively): Count the number of arguments produced,
12907 not the number of arguments given. This is simpler and lets GCC
12908 4.6.0 generate slightly better code.
12910 * ftfont.c: Distingish more carefully between FcChar8 and char.
12911 The previous code passed unsigned char * to a functions like
12912 strlen and xstrcasecmp that expect char *, which does not
12913 conform to the C standard.
12914 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12915 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12916 char * when the C standard requires it.
12918 * keyboard.c (read_char): Remove unused var.
12920 * eval.c: Port to Windows vsnprintf (Bug#8435).
12921 Include <limits.h>.
12922 (SIZE_MAX): Define if the headers do not.
12923 (verror): Do not give up if vsnprintf returns a negative count.
12924 Instead, grow the buffer. This ports to Windows vsnprintf, which
12925 does not conform to C99. Problem reported by Eli Zaretskii.
12926 Also, simplify the allocation scheme, by avoiding the need for
12927 calling realloc, and removing the ALLOCATED variable.
12929 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12931 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12932 But keep the doprint source code for now, as we might revamp it
12933 and use it again (Bug#8435).
12934 * lisp.h (doprnt): Remove.
12935 * Makefile.in (base_obj): Remove doprnt.o.
12936 * deps.mk (doprnt.o): Remove.
12938 error: Print 32- and 64-bit integers portably (Bug#8435).
12939 Without this change, on typical 64-bit hosts error ("...%d...", N)
12940 was used to print both 32- and 64-bit integers N, which relied on
12941 undefined behavior.
12942 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12943 * lisp.h (error, verror): Mark as printf-like functions.
12944 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12945 Report overflow in size calculations when allocating printf buffer.
12946 Do not truncate output string at its first null byte.
12947 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12948 Truncate the output at a character boundary, since vsnprintf does not
12950 * charset.c (check_iso_charset_parameter): Convert internal
12951 character to string before calling 'error', since %c now has the
12953 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12954 overflow when computing char to be passed to 'error'. Do not
12955 pass Lisp_Object to 'error'; pass the integer instead.
12956 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12957 formatted with plain %d.
12959 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12961 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12963 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12965 * xterm.c (x_catch_errors): Remove duplicate declaration.
12967 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12969 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12971 2011-04-10 Jim Meyering <meyering@redhat.com>
12973 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12974 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12975 return ssize_t not "int", and use size_t as the buffer length.
12976 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12977 * gnutls.h: Update declarations.
12978 * process.c (read_process_output): Use ssize_t, to match.
12979 (send_process): Likewise.
12981 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12983 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12985 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12987 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12988 Use unsigned char, to match FcChar8 type definition.
12990 * xterm.c (handle_one_xevent):
12991 * xmenu.c (create_and_show_popup_menu):
12992 * xselect.c (x_decline_selection_request)
12993 (x_reply_selection_request): Avoid type-punned deref of X events.
12995 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12997 Fix some uses of `int' instead of EMACS_INT.
12998 * search.c (string_match_1, fast_string_match)
12999 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13000 (scan_buffer, find_next_newline_no_quit)
13001 (find_before_next_newline, search_command, Freplace_match)
13002 (Fmatch_data): Make some `int' variables be EMACS_INT.
13004 * xdisp.c (display_count_lines): 3rd argument and return value now
13005 EMACS_INT. All callers changed.
13006 (pint2hrstr): Last argument is now EMACS_INT.
13008 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13009 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13010 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13021 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13022 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13024 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13025 (encode_invocation_designation): Last argument P_NCHARS is now
13027 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13028 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13030 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13033 * ccl.c (Fccl_execute_on_string): Declare some variables
13036 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13038 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13040 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13042 * process.c (Fformat_network_address): Doc fix.
13044 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13046 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13048 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13050 * keyboard.c (read_char): Call Lisp function help-form-show,
13051 instead of using internal_with_output_to_temp_buffer.
13052 (Qhelp_form_show): New var.
13053 (syms_of_keyboard): Use DEFSYM macro.
13055 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13062 (list_processes_1): Delete.
13064 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13066 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13068 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13070 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13072 Fix more problems found by GCC 4.6.0's static checks.

13078 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13080 * xdisp.c (vmessage): Mark as a printf-like function.
13082 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13084 * sound.c (sound_warning): Don't crash if arg contains a printf format.

13089 to system-supplied API.
13091 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13093 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13094 This avoids several warnings with gcc -Wstrict-overflow.
13095 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13096 directly, rather than having caller test rule sign. This avoids
13097 some unnecessary tests.
13098 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13099 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13100 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13102 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13103 (xfont_open): Avoid unnecessary tests.
13105 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13107 * composite.h, composite.c (composition_gstring_put_cache):
13108 Use EMACS_INT, not int, for length.
13110 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13111 breaking out part of COMPOSITION_DECODE_RULE.
13112 (COMPOSITION_DECODE_RULE): Use it.
13113 * composite.c (get_composition_id): Remove unused local vars,
13114 by using the new macro.
13116 * textprop.c (set_text_properties_1): Change while to do-while,
13117 since the condition is always true at first.
13119 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13120 (interval_deletion_adjustment): Return unsigned value.
13123 * process.c (list_processes_1, create_pty, read_process_output):
13124 (exec_sentinel): Remove vars that were set but not used.
13125 (create_pty): Remove unnecessary "volatile"s.
13126 (Fnetwork_interface_info): Avoid possibility of int overflow.
13127 (read_process_output): Do adaptive read buffering even if carryover.
13128 (read_process_output): Simplify nbytes computation if buffered.

13139 * print.c (print_error_message): Avoid int overflow.
13141 * font.c (font_list_entities): Redo for clarity,
13142 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13144 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13145 (font_score): Avoid potential overflow in diff calculation.
13147 * fns.c (substring_both): Remove var that is set but not used.
13148 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13150 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13152 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13153 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13154 can always succeed if overflow has undefined behavior.
13156 * search.c (boyer_moore, wordify): Remove vars set but not used.
13157 (wordify): Omit three unnecessary tests.
13159 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13160 All callers changed. This avoids the need for an unused var.
13162 * casefiddle.c (casify_region): Remove var that is set but not used.
13164 * dired.c (file_name_completion): Remove var that is set but not used.
13166 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13168 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13169 (Finsert_file_contents): Remove unnecessary code checking fd.
13171 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13172 Check for integer overflow on size calculations.
13174 * buffer.c (Fprevious_overlay_change): Remove var that is set
13177 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13178 Remove vars that are set but not used.
13179 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13180 (timer_check_2): Mark vars as initialized.
13182 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13184 * image.c (lookup_image): Remove var that is set but not used.
13185 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13187 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13188 that are set but not used.
13190 * xfns.c (make_invisible_cursor): Don't return garbage
13191 if XCreateBitmapFromData fails (Bug#8410).
13193 * xselect.c (x_get_local_selection, x_handle_property_notify):
13194 Remove vars that are set but not used.
13196 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13197 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13199 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13200 Remove var that is set but not used.
13201 (scroll_bar_windows_size): Now size_t, not int.
13202 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13203 Check for overflow.
13205 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13206 (map_tty_color) [!defined MSDOS]: Likewise.
13208 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13210 * coding.c: Remove vars that are set but not used.
13211 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13212 All callers changed.
13213 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13214 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13215 (decode_coding_charset): Remove vars that are set but not used.
13217 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13218 that is set but not used.
13220 * print.c (print_object): Remove var that is set but not used.
13222 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13223 The gnulib version avoids calling malloc in the usual case,
13224 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13225 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13226 * filelock.c (current_lock_owner): Likewise.
13227 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13228 * sysdep.c: Include allocator.h, careadlinkat.h.
13229 (emacs_no_realloc_allocator): New static constant.
13230 (emacs_readlink): New function.
13231 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13232 ../lib/careadlinkat.h.
13234 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13236 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13237 first non-nil return value).
13239 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13241 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13242 if not defined (Bug#8403).
13244 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13246 * xdisp.c (display_count_lines): Remove parameter `start',
13247 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13248 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13249 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13251 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13252 and thereabouts. All callers changed.
13253 (get_per_char_metric): Remove parameter `f', unused since
13254 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13256 2011-04-02 Jim Meyering <meyering@redhat.com>
13258 do not dereference NULL upon failed strdup
13259 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13260 (ns_get_family): Likewise.
13262 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13264 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13266 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13268 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13271 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13273 Add lexical binding.
13275 * window.c (Ftemp_output_buffer_show): New fun.
13276 (Fsave_window_excursion):
13277 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13279 * lread.c (lisp_file_lexically_bound_p): New function.
13280 (Fload): Bind Qlexical_binding.
13281 (readevalloop): Remove `evalfun' arg.
13282 Bind Qinternal_interpreter_environment.
13283 (Feval_buffer): Bind Qlexical_binding.
13284 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13286 (syms_of_lread): Declare `lexical-binding'.
13288 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13290 * keyboard.c (eval_dyn): New fun.
13291 (menu_item_eval_property): Use it.
13293 * image.c (parse_image_spec): Use Ffunctionp.
13295 * fns.c (concat, mapcar1): Accept byte-code-functions.
13297 * eval.c (Fsetq): Handle lexical vars.
13298 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13299 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13300 (FletX, Flet): Obey lexical binding.
13301 (Fcommandp): Handle closures.
13302 (Feval): New `lexical' arg.
13303 (eval_sub): New function extracted from Feval. Use it almost
13304 everywhere where Feval was used. Look up vars in lexical env.
13306 (Ffunctionp): Move from subr.el.
13307 (Ffuncall): Handle closures.
13308 (apply_lambda): Remove `eval_flags'.
13309 (funcall_lambda): Handle closures and new byte-code-functions.
13310 (Fspecial_variable_p): New function.
13311 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13312 but without exporting it to Lisp.
13314 * doc.c (Fdocumentation, store_function_docstring):
13315 * data.c (Finteractive_form): Handle closures.
13317 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13320 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13322 (exec_byte_code): New function extracted from Fbyte_code to handle new
13323 calling convention for byte-code-functions. Add new byte-codes.
13325 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13327 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13329 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13331 * xdisp.c (redisplay_internal): Fix prototype.
13333 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13335 * xdisp.c (SCROLL_LIMIT): New macro.
13336 (try_scrolling): Use it when setting scroll_limit.
13337 Limit scrolling to 100 screen lines.
13338 (redisplay_window): Even when falling back on "recentering",
13339 position point in the window according to scroll-conservatively,
13340 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13342 (try_scrolling): When point is above the window, allow searching
13343 as far as scroll_max, or one screenful, to compute vertical
13344 distance from PT to the scroll margin position. This prevents
13345 try_scrolling from unnecessarily failing when
13346 scroll-conservatively is set to a value slightly larger than the
13347 window height. Clean up the case of PT below the margin at bottom
13348 of window: scroll_max can no longer be INT_MAX. When aggressive
13349 scrolling is in use, don't let point enter the opposite scroll
13350 margin as result of the scroll.
13351 (syms_of_xdisp) <scroll-conservatively>: Document the
13352 threshold of 100 lines for never-recentering scrolling.
13354 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13356 * dispextern.h (move_it_by_lines):
13357 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13358 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13359 (message_log_check_duplicate): Remove parameters `prev_bol' and
13360 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13361 (redisplay_internal): Remove parameter `preserve_echo_area',
13362 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13364 * indent.c (Fvertical_motion):
13365 * window.c (window_scroll_pixel_based, Frecenter):
13366 Don't pass `need_y_p' to `move_it_by_lines'.
13368 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13370 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13371 steal a few bits to be more compact.
13372 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13373 Remove unneeded casts.
13375 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13377 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13379 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13380 binding" message (bug#7967).
13382 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13384 Fix more problems found by GCC 4.6.0's static checks.
13386 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13387 Remove unused local var.
13389 * editfns.c (Fmessage_box): Remove unused local var.
13391 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13392 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13393 Omit unused local vars.
13394 * window.c (shrink_windows): Omit unused local var.
13395 * menu.c (digest_single_submenu): Omit unused local var.
13396 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13397 Omit unused local var.
13399 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13400 Don't assume string length fits in int.
13401 (keyremap_step, read_key_sequence): Use size_t for sizes.
13402 (read_key_sequence): Don't check last_real_key_start redundantly.
13404 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13405 instead of alloca (Bug#8344).
13407 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13408 (Fbacktrace_frame): Don't assume nframes fits in int.
13410 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13412 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13415 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13417 * cm.c (calccost): Turn while-do into do-while, for clarity.
13419 * keyboard.c (syms_of_keyboard): Use the same style as later
13420 in this function when indexing through an array. This also
13421 works around GCC bug 48267.
13423 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13425 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13427 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13428 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13430 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13431 This avoids undefined behavior on integer overflow, and is a bit
13432 more convenient anyway since it is compared to a size_t variable.
13434 Variadic C functions now count arguments with size_t, not int.
13435 This avoids an unnecessary limitation on 64-bit machines, which
13436 caused (substring ...) to crash on large vectors (Bug#8344).
13437 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13438 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13446 * fns.c (concat): Likewise.
13447 * frame.c (x_set_frame_parameters): Likewise.
13448 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13449 0 if not found, not -1. All callers changed.
13451 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13452 (stack_copy_size): Now size_t, not int.
13453 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13455 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13457 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13458 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13459 All callers changed.
13461 * lisp.h (multibyte_char_to_unibyte):
13462 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13463 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13474 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13475 don't set the hook to nil, but remove the offending function instead.
13476 (Qcommand_hook_internal): Remove, unused.
13477 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13478 Vcommand_hook_internal.
13480 * eval.c (enum run_hooks_condition): Remove.
13481 (funcall_nil, funcall_not): New functions.
13482 (run_hook_with_args): Call each function through a `funcall' argument.
13483 Remove `cond' argument, now redundant.
13484 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13485 (Frun_hook_with_args_until_failure): Adjust accordingly.
13486 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

13496 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13497 All callers changed.
13499 * w32.c (_wsa_errlist): Use braces for struct initializers.
13501 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13502 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13503 All callers changed.

13648 * term.c (Fsuspend_tty, Fresume_tty):
13649 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13650 * window.c (temp_output_buffer_show):
13651 * insdel.c (signal_before_change):
13652 * frame.c (Fhandle_switch_frame):

13658 * buffer.c (Fkill_all_local_variables):
13659 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13661 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13662 unconditionally since it does the check itself.
13664 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13666 Fix more problems found by GCC 4.5.2's static checks.
13668 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13669 the first time through the loop, since we know p0 < p1 then.
13670 This also avoids a gcc -Wstrict-overflow warning.
13672 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13673 leading to a memory leak, possible in functions like
13674 load_charset_map_from_file that can allocate an unbounded number
13675 of objects (Bug#8318).
13677 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13678 that could (at least in theory) be that large.
13680 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13681 This is less likely to overflow, and avoids undefined behavior if
13682 overflow does occur. All callers changed. Use strtoul to scan
13683 for the unsigned long integer.
13684 (pint2hrstr): Simplify and tune code slightly.
13685 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13695 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13698 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13700 * process.c (Fmake_network_process): Use socklen_t, not int,
13701 where POSIX says socklen_t is required in portable programs.
13702 This fixes a porting bug on hosts like 64-bit HP-UX, where
13703 socklen_t is wider than int (Bug#8277).
13704 (Fmake_network_process, server_accept_connection):
13705 (wait_reading_process_output, read_process_output):
13708 * process.c: Rename or move locals to avoid shadowing.

13718 Make tparam.h and terminfo.c consistent.
13719 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13720 Include tparam.h instead, since it declares them.
13721 * cm.h (PC): Remove extern decl; tparam.h now does this.
13722 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13723 * terminfo.c: Include tparam.h, to check interfaces.
13724 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13725 (tparam): Adjust signature to match interface in tparam.h;
13726 this removes some undefined behavior. Check that outstring and len
13727 are zero, which they always are with Emacs.
13728 * tparam.h (PC, BC, UP): New extern decls.
13730 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13731 (xftfont_open): Rename locals to avoid shadowing.
13733 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13734 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

13745 * composite.c (composition_compute_stop_pos): Rename local to
13747 (composition_reseat_it): Remove unused locals.
13748 (find_automatic_composition, composition_adjust_point): Likewise.
13749 (composition_update_it): Mark var as initialized.
13750 (find_automatic_composition): Mark vars as initialized,
13751 with a FIXME (Bug#8290).

13754 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13755 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13756 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13757 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13758 to avoid shadowing.
13760 * textprop.c (property_change_between_p): Remove; unused.
13762 * intervals.c (interval_start_pos): Now static.
13764 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13770 Fix pointer signedness.
13771 (alsa_choose_format): Remove unused local var.
13772 (wav_play): Initialize a variable to 0, to prevent undefined
13773 behavior (Bug#8278).
13775 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13777 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13779 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13780 clobbering (Bug#8298).
13781 * sysdep.c (sys_subshell): Likewise.
13782 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13784 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13785 This should get cleaned up, so that child_setup has the
13786 same signature on all platforms.
13788 * callproc.c (call_process_cleanup): Now static.
13789 (relocate_fd): Rename locals to avoid shadowing.
13791 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13793 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13794 not to be necessary, and produces flickering.
13796 2011-03-20 Glenn Morris <rgm@gnu.org>
13798 * config.in: Remove file.
13800 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13802 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13803 are now in src/globals.h.
13804 (syms_of_minibuf): Remove spurious & from previous change.

13830 (sigchld_handler): Now static.
13832 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13833 That way, the code declares only the vars that it needs.

13843 (CONSTANTLIM): Remove; unused.
13844 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13845 Define only if needed.
13847 * unexelf.c (unexec): Name an expression,
13848 to avoid gcc -Wbad-function-cast warning.
13849 Use a different way to cause a compilation error if anyone uses
13850 n rather than nn, a way that does not involve shadowing.
13851 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13853 * deps.mk (unexalpha.o): Remove; unused.
13855 New file unexec.h, the (simple) interface for unexec (Bug#8267).

13922 (Ftranslate_region_internal, Fformat):
13923 Rename or remove local vars to avoid shadowing.

13926 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13929 * lisp.h (eassert): Check that the argument compiles, even if
13930 ENABLE_CHECKING is not defined.
13932 * data.c (Findirect_variable): Name an expression, to avoid
13933 gcc -Wbad-function-cast warning.

13950 (Fmemory_limit): Cast sbrk's returned value to char *.

13976 (RETALLOC_IF): Define only if needed.
13977 (WORDCHAR_P): Likewise. This one is never needed, but is used
13978 only in a comment talking about a compiler bug, so put inside
13979 the #if 0 of that comment.

14009 gcpro1, gcpro2, etc.
14010 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14012 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

14017 Rename locals to avoid shadowing.
14019 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

14028 (downcase, upcase1): New static inline functions.
14029 (DOWNCASE, UPCASE1): Reimplement using these functions.
14030 This avoids undefined behavior in expressions like

14061 so that gcc does not warn that these functions aren't declared.

14064 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

14071 * buffer.c (fix_overlays_before): Mark locals as initialized.
14072 (fix_start_end_in_overlays): Likewise. This function should be
14073 simplified by using pointers-to-pointers, but that's a different

14077 (report_overlay_modification): Rename locals to avoid shadowing.

14082 to suppress a gcc -Wclobbered warning that does not seem to be right.
14083 (MAXPATHLEN): Define only if needed.
14085 * process.c (serial_open, serial_configure): Move decls from here ...
14086 * systty.h: ... to here, so that they can be checked.

14432 a block, when the outer 'i' will do.

14445 -Wuninitialized does not deduce are never used uninitialized.
14446 (detect_coding_iso_2022): Initialize a local variable that might
14447 be used uninitialized. Leave a FIXME because it's not clear that
