72 does that unconditionally. Remove file, which is now empty.
74 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
77 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

228 2012-07-27 Eli Zaretskii <eliz@gnu.org>
230 * alloc.c (listn): Fix the order the arguments are consed onto the
233 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
234 enumeration constants, as PURE and HEAP are too general, and clash
235 with other headers and sources, such as gmalloc.c and the
236 MS-Windows system headers. All users changed.
238 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
240 Revert last save_excursion_save and save_excursion_restore changes.
241 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

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

256 complains about the types in the unevaluated arm when the argument
257 is an integer literal.
258 (xgetint): Simplify expression.
259 * alloc.c (gdb_make_enums_visible): New constant. This ports to
260 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
261 Zaretskii in <http://bugs.gnu.org/12036#13>.
262 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
263 needed now that we have gdb_make_enums_visible.
264 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

285 * xfns.c (syms_of_xfns): Likewise.
287 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
289 Fast save_excursion_save and save_excursion_restore.
290 * lisp.h (struct Lisp_Excursion): New data type.
291 (PVEC_EXCURSION): New pseudovector type.

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

322 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
323 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
324 not be usable in #if. This simplifies things.
326 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
328 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
330 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

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

375 add argument, tune behavior, and adjust all callers.
377 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
379 Use typedef for EMACS_INT, EMACS_UINT.
380 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
381 than macros. This simplifies debugging in the usual case, since
382 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
383 and it allows expressions involving EMACS_INT casts.
384 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
386 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
388 * nsterm.m (ns_read_socket): Return early if there is a modal

398 Adjust buffer text indirection counters at the end of Fkill_buffer.
399 * buffer.c (Fkill_buffer): Adjust indirection counters when the
400 buffer is definitely dead. This should really fix an issue reported
401 by Christoph Scholtes again. (Bug#12007).
402 (init_buffer_once): Initialize indirection counters of
403 buffer_defaults and buffer_local_symbols (for sanity and safety).
405 2012-07-24 Eli Zaretskii <eliz@gnu.org>
407 * xdisp.c (init_iterator): Don't compute dimensions of truncation
408 and continuation glyphs on tooltip frames, leave them at zero.
409 Avoids continued lines in tooltips. (Bug#11832)
411 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
413 Simplify copy_overlay.
414 * buffer.c (copy_overlay): Simplify. Use build_marker.

420 or invalid. (Bug#12025)
422 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
423 it signals an error when a tooltip frame is being created.
425 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
427 Cleanup miscellaneous objects allocation and initialization.
428 * alloc.c (allocate_misc): Change to static. Add argument to

436 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
438 Swap buffer text indirection counters in Fbuffer_swap_text.
439 * buffer.c (Fbuffer_swap_text): Swap indirections too.
440 This avoids crash reported by Christoph Scholtes at
441 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
443 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
445 * nsmenu.m (Popdown_data): New struct.
446 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
448 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
449 (initWithContentRect): Make imgView and contentView non-static
450 and autorelease them. Also autorelease img and matrix (Bug#12005).

1199 * s/aix4-2.h (unix): Remove; no longer needed.
1201 EMACS_TIME simplification (Bug#11875).
1202 This replaces macros (which typically do not work in GDB)

1204 The functional style also makes code easier to read and maintain.
1205 * systime.h: Include <sys/time.h> on all hosts, not just if
1206 WINDOWSNT, since 'struct timeval' is needed in general.

1246 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1247 Prefer snprintf to strncpy.
1248 * nsterm.m (ns_term_init):
1249 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1250 * nsterm.m (ns_term_init):
1251 Avoid the need for strncpy, by using build_string or
1252 make_unibyte_string directly. Use dtoastr, not snprintf.
1253 * process.c (Fmake_network_process): Diagnose service names that
1254 are too long, rather than silently truncating them or creating
1255 non-null-terminated names.
1256 (Fnetwork_interface_info): Likewise, for interface names.
1257 * sysdep.c (system_process_attributes) [GNU_LINUX]:

1272 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1273 where argument type is known to be a Lisp_Cons.

1289 the function is called with compile-time constant argument.
1290 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1291 argument, adjust users accordingly. Use build_pure_c_string where

1325 We include usg5-4-common.h, which defines them both.
1327 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1328 O_RDONLY already includes it).
1330 Stop ns builds setting the EMACSLOADPATH environment variable.
1331 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1332 Now it does not set EMACSLOADPATH, just returns the load-path string.
1333 * nsterm.h: Update accordingly.
1334 * lread.c [HAVE_NS]: Include nsterm.h.
1335 (init_lread) [HAVE_NS]: Use ns_load_path.
1336 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1338 2012-07-09 Glenn Morris <rgm@gnu.org>
1340 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,

1345 (ns_init_paths): Do not set EMACSPATH.
1346 * nsterm.h (ns_exec_path): Add it.

1350 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1352 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1354 * process.c (wait_reading_process_output): 'waitchannels' was unset

1378 Use make_formatted_string to avoid double length calculation.
1379 * lisp.h (make_formatted_string): New prototype.
1380 * alloc.c (make_formatted_string): New function.
1381 * buffer.c (Fgenerate_new_buffer_name): Use it.

1384 * filelock.c (get_boot_time): Likewise.
1385 * frame.c (make_terminal_frame, set_term_frame_name)
1386 (x_report_frame_params): Likewise.
1387 * image.c (gs_load): Likewise.

1399 * nsterm.h (ns_etc_directory): Add it.
1400 * callproc.c [HAVE_NS]: Include nsterm.h.
1401 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1403 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1405 Move marker debugging code under MARKER_DEBUG.
1406 * marker.c (MARKER_DEBUG): Move marker debugging code under
1407 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1408 for bootstrap with --enable-checking (~3x slowdown reported
1409 by Juanma Barranquero <lekktu@gmail.com>).
1410 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1412 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1414 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1415 See <http://bugs.gnu.org/11825#29>.
1417 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1419 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1420 has no font, use the frame's font. (Bug#11813)
1421 (display_line): Add commentary about displaying truncation glyphs
1423 (produce_special_glyphs): Move here from term.c.
1425 * term.c (produce_special_glyphs): Move to xdisp.c.
1427 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1430 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1432 * xdisp.c (display_line): Avoid warning about implicit declaration
1435 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1437 * lisp.h: Remove empty conditional.
1439 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1441 * lread.c (load_path_check): Now static.
1443 Fix some minor --with-ns problems found by static checking.
1444 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1445 (x_set_font) [!HAVE_X_WINDOWS]:
1446 * image.c (xpm_load_image) [HAVE_NS]:
1447 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1448 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1449 Remove unused local.
1450 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1451 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1452 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1453 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1454 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1455 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1456 Fix pointer signedness problem.
1457 * xfaces.c (FRAME_X_FONT_TABLE):
1458 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1460 2012-07-07 Glenn Morris <rgm@gnu.org>
1462 * lread.c (load_path_check): New function, split from init_lread.
1463 (init_lread): Reorganize. Motivation:
1464 If EMACSLOADPATH is set, check/warn about that rather than the
1465 defaults, which we are not going to use. Hence we can remove
1466 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1467 Don't warn if site-lisp directories are missing.
1468 If not installed, start from a blank load-path, since
1469 PATH_LOADSEARCH refers to the eventual installation directories.
1471 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1473 Support truncation and continuation glyphs on GUI frames, when
1474 fringes are disabled. (Bug#11832)
1475 * xdisp.c (init_iterator): Get dimensions of truncation and
1476 continuation glyphs even if on GUI frames. Adjust
1477 it->last_visible_x on GUI frames when the left or right fringes,
1478 or both, are absent.
1479 (start_display, move_it_in_display_line_to): Handle the case of a
1480 GUI frame without a fringe to display continuation or truncation
1482 (insert_left_trunc_glyphs): Support GUI frames: make sure
1483 truncation glyphs overwrite enough glyphs from the current line to
1484 have sufficient space in pixels.
1485 (display_line): Support truncation and continuation glyphs on GUI
1486 frames. If some spare pixels are left on the line after inserting
1487 the truncation glyphs, fill that space with a stretch glyph of a
1488 suitably computed width.
1490 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1491 produce_glyphs, to support GUI sessions.
1493 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1495 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1497 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1499 Do not require float-time's arg to fit in time_t (Bug#11825).
1500 This works better on hosts where time_t is unsigned, and where
1501 float-time is applied to the (negative) difference between two times.
1502 * editfns.c (decode_time_components): Last arg is now double *,
1503 not int *, and means to store all the result as a double, without
1504 worrying about whether the seconds part fits in time_t.
1505 All callers changed.
1506 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1507 All callers changed.
1508 (Ffloat_time): Do not fail merely because the specified time falls
1509 outside of time_t range.
1511 2012-07-07 Glenn Morris <rgm@gnu.org>
1513 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1519 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1520 Update dependencies.
1522 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1524 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1526 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1527 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1528 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1529 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1530 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1531 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1533 * xfont.c (compare_font_names): Redo to omit the need for casts.
1535 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1537 * xfns.c (Fx_change_window_property): Doc fix.
1538 * w32fns.c (Fx_change_window_property): Doc fix.
1540 * w32fns.c (Fx_window_property): Accept the same arguments as the
1541 X Windows version. Doc fix.
1542 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1544 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1545 Eli Zaretskii <eliz@gnu.org>
1547 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1548 Windows-specific code from nt/config.nt moved here.
1549 Obsolete settings removed.
1551 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1553 * process.c: Avoid unnecessary calls to gettime.
1554 (wait_reading_process_output): Don't get the time of day
1555 when gobbling data immediately and not waiting, as there's no need
1556 for it in that case. This removes a FIXME.
1558 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1560 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1561 is defined (Bug#11768).
1563 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1565 Fix marker debugging code.
1566 * marker.c (byte_char_debug_check): Do not perform the check
1567 if buffer is not multibyte.
1568 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1569 Call byte_char_debug_check with correct arguments.
1571 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1573 Compile marker debugging code only if ENABLE_CHECKING is defined.
1574 * marker.c (byte_char_debug_check, count_markers):
1575 Use only if ENABLE_CHECKING is defined.
1576 (byte_debug_flag): Remove.
1577 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1578 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1580 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1582 Avoid code repetition in marker-related functions.
1583 * marker.c (attach_marker): New function.
1584 (Fset_marker, set_marker_restricted, set_marker_both)
1585 (set_marker_restricted_both): Use it.
1586 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1587 Consistently rename charno to charpos.
1588 (marker_position): Add eassert.
1589 (marker_byte_position): Convert to eassert.

1602 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1603 * composite.c (autocmp_chars): Likewise.
1604 * editfns.c (buildmark): Remove.
1605 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1606 (save_restriction_save): Use build_marker.
1607 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1608 * window.c (save_window_save): Likewise.
1610 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1612 Do not use Fdelete_overlay in delete_all_overlays
1613 to avoid redundant calls to unchain_overlay.
1614 * buffer.c (drop_overlay): New function.
1615 (delete_all_overlays, Fdelete_overlay): Use it.
1616 * minibuf.c (get_minibuffer): Fix comment.
1618 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1620 Port to OpenBSD 5.1 amd64.
1621 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1622 This is needed for OpenBSD, and should be harmless on all BSD systems.
1623 Also, include <sys/sysctl.h>, as it should be available on all
1624 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1625 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1626 use p_pid member, not kp_proc.pid.
1628 2012-07-06 Glenn Morris <rgm@gnu.org>
1630 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1632 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1634 More xmalloc and related cleanup.
1635 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1636 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

1641 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
1642 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1643 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1645 Omit needless casts involving void * pointers and allocation.
1646 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1647 as the former is more robust if P's type is changed.
1648 Prefer xzalloc to xmalloc + memset 0.
1649 Simplify malloc-or-realloc to realloc.
1650 Don't worry about xmalloc returning a null pointer.
1651 Prefer xstrdup to xmalloc + strcpy.
1652 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1654 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1655 alloca of a constant.
1657 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1659 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1660 hscroll is larger than the line width. Fixes long and futile
1661 looping inside extend_face_to_end_of_line (on a TTY) producing
1662 glyphs that are not needed and thrown away.
1664 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1666 * marker.c (set_marker_restricted_both): Simplify by using
1669 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1671 * editfns.c (region_limit): Simplify by using clip_to_bounds.

1680 followed by gtk_box_set_homogeneous (Bug#11768).
1681 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1682 (update_theme_scrollbar_width, xg_create_scroll_bar):
1683 Use gtk_scrollbar_new (Bug#11768).
1684 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1685 (is_box_type): New function (Bug#11768).
1686 (xg_tool_item_stale_p): Call is_box_type.
1687 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1688 with default display (Bug#11768).
1690 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1692 * xdisp.c (window_hscroll_limited): New function.
1693 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1694 coordinates when window's hscroll is set to insanely large
1697 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1699 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1700 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

1761 Problem reported by Troels Nielsen in
1762 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

1766 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1767 This should be fixed in a better way; see Eli Zaretskii in
1768 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1769 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1771 * fileio.c (time_error_value): Rename from special_mtime.
1772 The old name's problems were noted by Eli Zaretskii in
1773 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1775 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1776 This variable's comment says Emacs needs at least one GDB-visible
1777 symbol of type enum pvec_type, to work around GDB problems.
1778 The symbol's value doesn't matter.
1780 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1781 that causes compilation to fail on pre-C99 compilers.
1783 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1785 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1798 (PSEUDOVECTOR_SIZE_BITS): New constant.
1799 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1800 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1801 change in pvec_type.
1802 (PSEUDOVECTOR_TYPEP): New macro.
1803 (TYPED_PSEUDOVECTORP): Use it.
1804 * fns.c (internal_equal): Adapt code to extract pvectype.
1805 * emacs.c (gdb_pvec_type): Update type.
1806 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1807 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1808 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1809 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1810 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1811 abusing vector->header.next.nbytes.
1812 (live_vector_p): Use PVEC_TYPE.
1813 (mark_object): Adapt code to extract pvectype. Use switch.
1815 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1817 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1818 Tighten new eassert a bit.
1820 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1822 Fix compilation with --enable-gcc-warnings and -O1
1824 * doprnt.c (doprnt): Change type of tem to int, initialize
1825 to avoid compiler warning. Add eassert.
1826 * search.c (simple_search): Initialize match_byte to avoid
1827 compiler warning. Add eassert.
1829 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1831 Avoid weird behavior with large horizontal scrolls.
1832 Without this change, for example, large hscroll values would
1833 mess up Emacs's display on Fedora 15 x86, presumably due to
1834 overflows in int calculations in the display code.
1835 Also, if buffers had long lines, Emacs would freeze.
1836 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1837 (set_window_hscroll): New function, containing the old guts of
1838 Fset_window_hscroll. Return the clipped value.
1839 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1840 This avoids the need to check against PTRDIFF_MAX.
1842 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1844 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1846 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1848 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1850 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1851 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1852 since GCC 4.4.6 issues a bogus warning for them.
1854 Fix bugs in file timestamp newness comparisons.
1855 * fileio.c (Ffile_newer_than_file_p):
1856 * lread.c (Fload): Use full timestamp resolution of files,
1857 not just the 1-second resolution, so that files that are only
1858 slightly newer still count as newer.
1859 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1860 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1862 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1864 * fileio.c: Improve handling of file time marker. (Bug#11852)
1865 (special_mtime): New function.
1866 (Finsert_file_contents, Fverify_visited_file_modtime):
1867 Use it to set special mtime values consistently.
1869 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1871 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1872 marker for non-existing file. (Bug#11852)
1874 2012-07-03 Glenn Morris <rgm@gnu.org>
1876 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1877 and did not make it into globals.h).
1879 2012-07-03 Tom Tromey <tromey@redhat.com>
1881 * window.c (Fset_window_margins, Fset_window_fringes)
1882 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

1925 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1926 values which aren't power of 2.
1927 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1928 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1931 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1933 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1935 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1937 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1939 * alloc.c (allocate_vector_block): Remove redundant
1940 calls to mallopt if DOUG_LEA_MALLOC is defined.
1941 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1942 avoid calls to mallopt if zero_vector is returned.
1944 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1946 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1947 is enabled, avoid dereferencing NULL current_sblock if
1950 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1952 Cleanup basic buffer management.
1953 * buffer.h (struct buffer): Change layout to use generic vector
1954 marking code. Fix some comments. Change type of 'clip_changed'
1955 to bitfield. Remove unused #ifndef old.
1956 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1957 (GET_OVERLAYS_AT): Fix indentation.
1958 (for_each_per_buffer_object_at): New macro.
1959 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1960 (Fbuffer_local_variables): Use it.
1961 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1962 * alloc.c (allocate_buffer): Adjust to match new layout of
1963 struct buffer. Fix comment.
1964 (mark_overlay): New function.
1965 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1966 Lisp area of struct buffer.
1967 (mark_object): Use it. Adjust marking of misc objects
1968 and related comments.
1970 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1972 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1973 wrapper that is not needed because the wrapped code is a no-op (zero
1974 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1975 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1977 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1979 * alloc.c (mark_buffer): Simplify. Remove prototype.
1980 (mark_object): Add comment. Reorganize marking of vector-like
1981 objects. Use CHECK_LIVE for all vector-like objects except buffers
1982 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1983 redundant calls to mark_vectorlike for bool vectors.
1985 2012-06-30 Glenn Morris <rgm@gnu.org>
1987 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1989 * epaths.in (PATH_SITELOADSEARCH): New.
1990 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1991 This is rather than relying on --enable-locallisppath elements
1992 having "site-lisp" in their names. (Bug#10208#25, 11658)
1994 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1996 * w32proc.c (sys_select): Accept and ignore one more argument.
1998 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2000 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2001 (pselect) [!MS_DOS]: Redirect to sys_select.
2003 * sysdep.c: Don't include dos.h and dosfns.h.
2005 * process.c (sys_select):
2006 * msdos.c (sys_select): Accept one more argument and ignore it.
2008 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2009 adapt data types and code to that.
2012 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2013 which clashes with the gnulib function of the same name.
2015 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2017 * font.c (font_style_to_value, font_style_symbolic)
2018 (font_prop_validate_style): Add type checks for values in
2021 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2023 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2026 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2028 * xdisp.c (try_window_id): Undo last change.
2030 * w32.c (getwd): Adjust commentary about startup_dir.
2031 (init_environment): Always call sys_access, even in non-MSVC
2032 builds. Don't chdir to the directory of the Emacs executable.
2033 This undoes code from 1997 which was justified by the need to
2034 "avoid conflicts when removing and renaming directories". But its
2035 downside was that every relative file name was being interpreted
2036 relative to the directory of the Emacs executable, which can never
2037 be TRT. In particular, it broke sys_access when called with
2038 relative file names.
2039 (sys_access): Map GetLastError to errno.
2041 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2043 * window.h (struct window): Change type of 'fringes_outside_margins'

2047 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2050 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2052 * gnutls.c (emacs_gnutls_handshake):
2053 Add QUIT to make the loop interruptible.
2055 2012-06-29 Glenn Morris <rgm@gnu.org>
2057 * charset.c (init_charset): Make lack of etc/charsets fatal.
2059 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2061 * editfns.c (region_limit): Fix type mismatch.
2063 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2065 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2066 undefined. Convert from xassert to eassert.
2067 * nsmenu.m: Convert from xassert to eassert.
2068 * nsterm.m: Likewise.
2070 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2072 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2074 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2076 Avoid integer overflow on scroll-left and scroll-right.
2077 * window.c (HSCROLL_MAX): New macro.
2078 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2079 overflow when requested scroll falls outside ptrdiff_t range.
2081 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2083 * window.h (struct window): Change type of 'hscroll',
2084 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2085 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2086 Adjust users accordingly.
2087 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2088 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2089 from EMACS_INT to ptrdiff_t.
2090 (make_window): Omit redundant initialization.
2092 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2096 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2098 * window.h (struct window): Change type of 'use_time' and
2099 'sequence_number' from Lisp_Object to int.

2109 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2110 adjust comments accordingly.

2161 avoid GCC warning about unused macro.
2163 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2165 * alloc.c (allocate_string): Omit intervals initialization.
2166 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2167 as in make_pure_string and make_pure_c_string.
2169 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2171 * alloc.c (allocate_string): Fix last change.
2173 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2223 * alloc.c: Remove build_string.
2224 * lisp.h: Define build_string as static inline. This provides
2225 a better opportunity to optimize away calls to strlen when the
2226 function is called with compile-time constant argument.
2227 * image.c (imagemagick_error): Convert to build_string.
2228 * w32proc.c (sys_spawnve): Likewise.
2229 * xterm.c (x_term_init): Likewise.
2231 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2233 Use sprintf return value instead of invoking strlen on result.
2234 In the old days this wasn't portable, since some sprintf
2235 implementations returned char *. But they died out years ago and
2236 Emacs already assumes sprintf returns int.
2237 Similarly for float_to_string.
2238 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2239 * ccl.c (ccl_driver):
2240 * character.c (string_escape_byte8):

2243 * print.c (print_object):
2244 * xdisp.c (message_dolog):
2245 * xfns.c (syms_of_xfns):
2246 Use sprintf or float_to_string result to avoid need to call strlen.
2247 * data.c (Fnumber_to_string):
2248 Use make_unibyte_string, since the string must be ASCII.
2249 * lisp.h, print.c (float_to_string): Now returns int length.
2250 * term.c (produce_glyphless_glyph):
2251 Use sprintf result rather than recomputing it.
2253 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2254 * Makefile.in (ALL_CFLAGS):
2255 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2261 strcasecmp if available.

2284 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2286 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2289 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2291 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2292 instead of truncating it to 63 (admittedly a generous limit).
2294 * process.c: Fix spelling and caps in comments.
2296 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2298 * emacs.c (setpgrp): Remove definition, unused.

2310 * systime.h [WINDOWSNT]: Include sys/time.h.
2312 * s/ms-w32.h (struct timespec): Definition moved from
2313 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

2422 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2424 Support higher-resolution time stamps (Bug#9000).
2425 The time stamps are only nanosecond-resolution at the C level,
2426 since that's the best that any real-world system supports now.
2427 But they are picosecond-resolution at the Lisp level, as that's
2428 easy, and leaves room for future OS improvements.
2430 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2433 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2434 Don't get current time unless it's needed.
2436 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2437 now provides it if it's absent.
2438 (start_atimer): Port to higher-res time stamps.
2439 Check for time stamp overflow. Don't get current time more
2440 often than is needed.
2442 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2443 Include systime.h, not time.h.
2444 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2446 * dired.c: Include stat-time.h.
2447 (Ffile-attributes): File times now have higher resolution.

2450 (struct image): Timestamp now has higher resolution.
2452 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2453 has at least microseconds now. All uses removed.
2454 (update_frame, update_single_window, update_window, update_frame_1)
2455 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2457 * editfns.c (time_overflow): Now extern.
2458 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2463 (decode_time_components, lisp_seconds_argument): New functions.
2464 (make_time): Now static.
2465 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2466 Report an error if the time is invalid, rather than having the caller
2469 * fileio.c: Include <stat-time.h>
2470 (Fcopy_file): Copy higher-resolution time stamps.
2471 Prefer to set the time stamp via a file descriptor if that works.
2472 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2473 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2474 (Fvisited_file_modtime, Fset_visited_file_modtime):
2475 Support higher-resolution time stamps.
2477 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2479 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2481 * image.c (prepare_image_for_display, clear_image_cache)
2482 (lookup_image): Port to higer-resolution time stamps.
2484 * keyboard.c (start_polling, bind_polling_period):
2485 Check for time stamp overflow.
2486 (read_char, kbd_buffer_get_event, timer_start_idle)
2487 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2488 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2489 Port to higher-resolution time stamps. Do not assume time_t is signed.
2490 (decode_timer): New function. Timers are now vectors of length 9,
2491 not 8, to accommodate the picosecond component.
2492 (timer_check_2): Use it.
2494 * nsterm.m (select_timeout, timeval_subtract): Remove.
2495 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2496 as they're a bit more accurate and handle overflow better.
2497 (ns_select): Change prototype to be compatible with pselect.
2498 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2499 * nsterm.h (ns_select): Adjust prototype.
2501 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2502 us-resolution time stamps.
2503 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2505 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2507 * lisp.h (time_overflow): New decl.
2508 (wait_reading_process_output): First arg is now intmax_t, not int,
2509 to accommodate larger waits.
2511 * process.h (struct Lisp_Process.read_output_delay):
2512 Now counts nanoseconds, not microseconds.
2513 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2515 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2516 (wait_reading_process_output):
2517 Port to ns-resolution time stamps.
2518 (Faccept_process_output, wait_reading_process_output):
2519 Check for time stamp overflow. Do not assume time_t is signed.
2520 (select_wrapper): Remove; we now use pselect.
2521 (Fprocess_attributes): Now generates ns-resolution time stamps.
2523 * sysdep.c: Include utimens.h. Don't include utime.h
2524 or worry about struct utimbuf; gnulib does that for us now.
2525 (gettimeofday): Remove; gnulib provides a substitute.
2526 (make_timeval): New function.
2527 (set_file_times): Now sets ns-resolution time stamps.
2528 New arg FD; all uses changed.
2529 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2530 (system_process_attributes):
2531 Now returns ns-resolution time stamp. All uses changed.
2532 Check for time stamp overflow.
2534 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2535 provides a substitute now.
2537 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2538 since it guarantees struct timespec.
2539 (EMACS_TIME): Now struct timespec, so that we can support
2540 ns-resolution time stamps.
2541 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2542 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2543 (EMACS_USECS): Remove.
2544 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2545 so multiply the arg by 1000 before storing it.
2546 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2548 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2549 Port to ns-resolution time stamps.
2550 (EMACS_TIME_NEG_P): Remove; replaced by....
2551 (EMACS_TIME_SIGN): New macro.
2552 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2553 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2554 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2555 (make_timeval, make_lisp_time, decode_time_components): New decls.
2556 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2557 that it mishandled time_t overflow. You can't compare by subtracting!
2558 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2559 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2561 * term.c: Include <sys/time.h>.
2562 (timeval_to_Time): New function, for proper overflow wraparound.

2567 (Fprimitive_undo): Use them when restoring time stamps.
2569 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2570 (w32_get_internal_run_time):
2571 Port to higher-resolution Emacs time stamps.
2572 (ltime): Now accepts single 64-bit integer, as that's more convenient
2575 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2577 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2578 for compatibility with pselect. Support ns-resolution time stamps.
2580 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2582 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2583 Check for time stamp overflow, and support ns-resolution time stamps.
2585 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2586 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2587 (timeval_subtract): Remove; no longer needed.
2588 (XTflash, XTring_bell, x_wait_for_event):
2589 Port to ns-resolution time stamps. Don't assume time_t is signed.
2591 2012-06-22 Chong Yidong <cyd@gnu.org>

2595 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2597 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2598 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2599 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2600 staticidx goes up to 1597 out of 1600 = 0x640.)
2602 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2604 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2605 Otherwise, the umask might be mistakenly 0 while handling input signals.

2627 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2629 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2630 since tty frames can be explicitly named.
2631 (prepare_menu_bars): Likewise.
2633 * term.c (Ftty_top_frame): New function.

2638 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2639 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2640 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2641 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2642 (METER_1, METER_2): Simplify.

2650 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2651 gets killed during executing of this function (Bug#11665).
2652 Try to always return Qt when the buffer has been actually killed.
2653 (Vkill_buffer_query_functions): In doc-string say that functions
2654 run by this hook should not change the current buffer.
2656 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2658 Fix recently-introduced process.c problems found by static checking.

2676 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2678 * lisp.h (eassert): Assume C89 or later.
2679 This removes the need for CHECK.
2680 (CHECK): Remove. Its comments about always evaluating its
2681 argument were confusing, as 'eassert' typically does not evaluate
2684 * coding.c (produce_chars): Use ptrdiff_t, not int.
2686 * xterm.c (x_draw_underwave): Check for integer overflow.
2687 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2839 * frame.c (delete_frame): Remove outdated comment.
2840 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
2841 USE_LISP_UNION_TYPE.

2858 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
2860 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2861 * alloc.c (make_number) [!defined make_number]:

2863 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
2864 (roundup_size): Verify that it is a power of 2.
2865 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
2866 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
2867 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
2868 -DUSE_LSB_TAG=0, to override the automatically-selected default.
2869 USE_LSB_TAG now is always defined to be either 0 or 1.
2871 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2872 code works fine either way, and efficiency is not a concern here,
2873 as the union type is for debugging, not for production.
2874 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2875 Use an inline function on all platforms when using the union type,
2876 since this is simpler and 'static inline' can be used portably
2878 (LISP_INITIALLY_ZERO): New macro.
2879 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2880 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

2949 dbus_type_is_basic if available.
2950 (xd_extract_signed, xd_extract_unsigned): Rename from
2951 extract_signed and extract_unsigned, respectively. Adapt callers.

2962 * xdisp.c (vmessage): Treat frame message as multibyte.
2963 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2964 would generate the diagnostic "Making \302\247 buffer-local while

2983 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2985 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2987 * alloc.c (allocate_vectorlike): Fix last change.
2989 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2991 Block-based vector allocation of small vectors.
2992 * lisp.h (struct vectorlike_header): New field `nbytes',
2993 adjust comment accordingly.

3018 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3020 * doprnt.c (doprnt): Truncate multibyte char correctly.
3021 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3022 would mishandle a string argument "Xc" if X was a multibyte
3023 character of length 2: it would truncate after X's first byte
3024 rather than including all of X.
3026 2012-06-06 Chong Yidong <cyd@gnu.org>
3028 * buffer.c (word_wrap): Doc fix.

3077 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3078 Convert pctcpu and pctmem to Lisp float properly.
3079 Let the compiler fold better, as 100.0/0x8000 is exact.
3081 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3083 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3086 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3088 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3090 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3092 For a 'struct window', replace some Lisp_Object fields to
3093 bitfields where appropriate, remove unused fields.
3094 * window.h (struct window): Remove unused 'last_mark_x' and
3095 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3096 change it's type from Lisp_Object to bitfield.
3097 Change type of 'force_start', 'optional_new_start',
3098 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3099 fields from Lisp_Object to bitfield. Adjust users accordingly.
3101 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3103 Pacify gcc -Wdouble-precision when using Xaw.
3104 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3105 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3106 Use 'float' consistently, rather than 'float' in most places
3107 and 'double' in a couple of places.
3109 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3111 * xdisp.c (handle_stop): Detect whether we have overlay strings
3112 loaded by testing it->current.overlay_string_index to be
3113 non-negative, instead of checking whether n_overlay_strings is
3114 positive. (Bug#11587)
3116 2012-05-31 Chong Yidong <cyd@gnu.org>
3118 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3120 * doc.c (Fsubstitute_command_keys): Doc fix.
3122 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3124 * search.c (search_buffer): Remove calls to
3125 r_alloc_inhibit_buffer_relocation, as it is now called by
3126 maybe_unify_char, which was the cause of relocation of buffer text
3129 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3131 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3132 for the duration of call to load_charset, to avoid problems with
3133 callers of maybe_unify_char that access buffer text through C
3136 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3137 decrement the inhibition flag, instead of just setting or
3140 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3142 Remove obsolete '#define static' cruft.
3143 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3144 This #undef was "temporary" in 2000; it is no longer needed
3145 now that '#define static' has gone away.
3146 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3147 (gray_bitmap_bits): Remove; no longer needed.
3148 All uses replaced with definiens.
3149 * xterm.c: Include "bitmaps/gray.xbm".
3151 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3153 Clean up __executable_start, monstartup when --enable-profiling.
3154 The following changes affect the code only when profiling.
3155 * dispnew.c (__executable_start): Rename from safe_bcopy.
3156 Define only on platforms that need it.
3157 * emacs.c: Include <sys/gmon.h> when profiling.
3158 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3159 (__executable_start): Remove decl, since lisp.h does it now.
3160 (safe_bcopy): Remove decl; no longer has that name.
3161 (main): Coalesce #if into single bit of code, for simplicity.
3162 Cast pointers to uintptr_t, since standard libraries want integers

3191 Do not create empty overlays with the evaporate property (Bug#9642).
3192 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3193 Bug#9642, but explicitly check that the buffer the overlay would
3194 be moved to is live and rearrange lines to make sure that errors
3195 will not put the overlay in an inconsistent state.
3196 (Fdelete_overlay): Cosmetics.
3198 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3200 * w32term.c (my_bring_window_to_top): New function.
3201 (x_raise_frame): Use handle returned by DeferWindowPos, which

3206 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3207 by calling BringWindowToTop.

3212 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3214 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3215 This avoids undefined behavior that might cause the eassert
3216 to not catch an out-of-range value.
3218 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3220 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3232 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3234 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3235 Only r_alloc_inhibit_buffer_relocation needed to be added;
3236 the others were already declared.
3238 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3239 before checking whether it's out of range. Put the check inside
3241 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3243 2012-05-27 Ken Brown <kbrown@cornell.edu>
3245 * callproc.c (Fcall_process): Restore a line that was accidentally
3246 commented out in the 2011-02-13 change (bug#11547).

3250 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3251 defined on ralloc.c.
3253 * buffer.c [REL_ALLOC]: Remove prototypes of
3254 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3255 they are now on lisp.h.
3257 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3259 * search.c (search_buffer): Use it to inhibit relocation of buffer
3260 text while re_search_2 is doing its job, because re_search_2 is
3261 passed C pointers to buffer text. (Bug#11519)
3263 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3266 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3267 state after an additional call to move_it_in_display_line_to, keep
3268 the values of it->max_ascent and it->max_descent found for the
3270 (pos_visible_p): Revert the comparison against bottom_y to what it
3271 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3274 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3276 Fix coding-related core dumps with gcc -ftrapv.
3277 The code was computing A - B, where A and B are pointers, and B is
3278 random garbage. This can lead to core dumps on platforms that
3279 have special pointer registers, and it also leads to core dumps on
3280 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3281 A - B only when B is initialized properly.

3305 gen_help_event to produce help-echo message in the echo area.
3306 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3309 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3311 * lread.c (read1): Simplify slightly to avoid an overflow warning
3312 with GCC 4.7.0 on x86-64.
3314 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3316 * bidi.c (bidi_mirror_char): Revert last change: an int is
3317 definitely wide enough here.
3319 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3321 Fix integer width and related bugs (Bug#9874).

3333 Use int, not EMACS_INT, where int is wide enough.

3353 (Foverlay_recenter, last_overlay_modification_hooks_used)
3354 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3355 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3356 (validate_region): Omit unnecessary test for b <= e,
3357 since that's guaranteed by the previous test.
3358 (adjust_overlays_for_delete): Avoid pos + length overflow.
3359 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3360 (report_overlay_modification):
3361 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3362 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3371 not int, to avoid needless 32-bit limit on 64-bit hosts.
3372 (exec_byte_code): Use tighter memory-full test, one that checks
3373 for alloca overflow. Don't compute the address of the object just
3374 before an array, as that's not portable. Use EMACS_INT, not
3375 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3376 * callint.c (Fcall_interactively):
3377 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3389 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3390 (casify_object): Avoid integer overflow when overallocating buffer.
3391 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3394 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3395 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3398 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3399 For CCL_MapSingle, check that content and value are in int range.

3401 Check that Vcode_version_map_vector is a vector.
3402 (resolve_symbol_ccl_program): Check that vector header is in range.
3403 Always copy the vector, so that we can check its contents reliably
3404 now rather than having to recheck each instruction as it's being
3405 executed. Check that vector words fit in 'int'.
3406 (ccl_get_compiled_code, Fregister_ccl_program)
3407 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3408 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3410 contents are in range.
3411 (Fccl_execute_on_string): Check that status is in range.
3412 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3413 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3414 Accept and return EMACS_INT, not int, because callers can pass values

3420 (string_escape_byte8, Fget_byte):
3421 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3423 avoid mishandling large integers.
3424 * character.h: Adjust decls to match defn changes elsewhere.

3434 Don't rely on undefined behavior with signed left shift overflow.
3435 Don't assume unsigned int fits into fixnum, or that fixnum fits
3436 into unsigned int. Don't require max_code to be a valid fixnum;
3437 that's not true for gb10830 4-byte on a 32-bit host. Allow
3438 invalid_code to be a cons, for the same reason. Require code_offset
3439 to be a character. Avoid int overflow if max_char is close
3441 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3442 this is intended anyway and avoids some undefined behavior.
3443 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3444 INDEX_TO_CODE_POINT, as that's what it expects.
3445 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3446 * charset.h (DECODE_CHAR): Return int, not unsigned;
3447 this is what was intended anyway, and it avoids undefined behavior.
3448 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3449 integer-overflow issues.
3450 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3451 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3452 where the argument is EMACS_INT, and this behavior is not intended.
3453 * chartab.c (Fmake_char_table, Fset_char_table_range)
3454 (uniprop_get_decoder, uniprop_get_encoder):
3455 Don't assume fixnum fits in int.
3456 * cmds.c (move_point): New function, that does the gist of
3457 Fforward_char and Fbackward_char, but does so while checking
3458 for integer overflow more accurately.
3459 (Fforward_char, Fbackward_char): Use it.
3460 (Fforward_line, Fend_of_line, internal_self_insert)
3461 (internal_self_insert):
3462 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4243 2012-05-14 Glenn Morris <rgm@gnu.org>
4245 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4246 Put "libexec" before "bin", for the sake of init_callproc_1.
4248 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4250 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

4253 (report_error, report_error_1, make_hdr, copy_sym)
4254 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4255 Make arguments const char *, not char *, to avoid violations of C
4256 standard and to fix some AIX warnings reported by Gilles Pion.
4258 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4260 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4261 already have overlays loaded.
4262 (handle_single_display_spec): Before returning without displaying
4263 fringe bitmap, synchronize the bidi iterator with the main display
4264 iterator, by calling iterate_out_of_display_property.
4265 (iterate_out_of_display_property): Detect buffer iteration by
4266 testing that it->string is a Lisp string.
4267 (get_next_display_element): When the current object is exhausted,
4268 and there's something on it->stack, call set_iterator_to_next to
4269 proceed with what's on the stack, instead of returning zero.
4270 (set_iterator_to_next): If called at the end of a Lisp string,
4271 proceed to consider_string_end without incrementing string
4272 position. Don't increment display vector index past the end of
4273 the display vector. (Bug#11417)
4274 (pos_visible_p): Don't report a position visible when move_it_to
4275 stopped at the last line of window, which happens to be scanned
4276 backwards by the bidi iteration. (Bug#11464)
4278 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4280 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4281 and right-margin display specs even if the spec is invalid or we
4282 are on a TTY, and thus unable to display on the fringes.
4283 That's because the text with the property will not be displayed anyway,
4284 so we need to signal to the caller that this is a "replacing"
4285 display spec. This fixes display when the spec is invalid or we
4288 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4290 * unexaix.c (make_hdr): Fix typo in prototype.
4291 This bug broke the build on AIX. Problem reported by Gilles Pion.
4293 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4295 * keyboard.c (kbd_buffer_get_event): Read special events also in
4296 batch mode. (Bug#11415)
4298 2012-05-12 Glenn Morris <rgm@gnu.org>

4306 2012-05-12 Glenn Morris <rgm@gnu.org>
4308 * Makefile.in (MKDIR_P): New, set by configure.
4309 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4311 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

4321 Update dependencies.
4323 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4325 * xgselect.c (xg_select): Put maxfds+1 into a var.
4326 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4328 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4330 2012-05-10 Dave Abrahams <dave@boostpro.com>
4332 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4333 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4335 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4337 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4338 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4339 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4340 Initialize xd_registered_buses.
4342 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4344 Untag more efficiently if USE_LSB_TAG.
4345 This is based on a proposal by YAMAMOTO Mitsuharu in
4346 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4347 For an admittedly artificial (nth 8000 longlist) benchmark on
4348 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4349 Emacs's overall text size by 1%.
4350 * lisp.h (XUNTAG): New macro.
4351 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4352 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4353 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4354 * eval.c (Fautoload):
4355 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4356 * frame.h (XFRAME): Use XUNTAG.
4358 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4359 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4360 Remove unportable assumptions about print widths of types like
4362 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4363 intptr_t when converting between pointer and integer, to avoid GCC
4364 warnings about wrong width.
4366 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4368 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4369 stack for each reader_thread, instead of defaulting to 8MB
4370 determined by the linker. This avoids failures in creating
4371 subprocesses on Windows 7, see the discussion in this thread:
4372 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4374 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4376 Fix up display of the *Minibuf-0* buffer in the mini window.
4377 * keyboard.c (read_char): Don't clear the echo area if there's no
4379 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4380 contents of *Minibuf-0*) if there's no message displayed in its stead.
4382 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4384 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4387 2012-05-06 Chong Yidong <cyd@gnu.org>
4389 * lisp.mk (lisp): Update.
4391 2012-05-05 Jim Meyering <meyering@redhat.com>
4393 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4395 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4397 * data.c (PUT_ERROR): New macro.
4398 (syms_of_data): Use it. Add new error type `user-error'.
4399 * undo.c (user_error): New function.
4400 (Fprimitive_undo): Use it.
4401 * print.c (print_error_message): Adjust print style for `user-error'.
4402 * keyboard.c (user_error): New function.
4403 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.

4407 Do not limit current-time-string to years 1000..9999.
4408 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4409 (Fcurrent_time_string): Support any year that is supported by the
4410 underlying localtime representation. Don't use asctime, as it
4411 has undefined behavior for years outside the range -999..9999.
4413 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4415 Fix race conditions involving setenv, gmtime, localtime, asctime.
4416 Without this fix, interrupts could mess up code that uses these
4417 nonreentrant functions, since setting TZ invalidates existing
4418 tm_zone or tzname values, and since most of these functions return
4419 pointers to static storage.
4420 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4421 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4422 Grow the critical sections to include not just invoking
4423 localtime/gmtime, but also accessing these functions' results
4424 including their tm_zone values if any, and any related TZ setting.
4425 (format_time_string): Last arg is now struct tm *, not struct tm **,
4426 so that the struct tm is saved in the critical section.
4427 All callers changed. Simplify allocation of initial buffer, partly
4428 motivated by the fact that memory allocation needs to be outside
4429 the critical section.
4431 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4433 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4434 with RESET_INTERVAL.
4436 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4437 Remove duplicated buffer name initialization.
4439 2012-05-02 Jim Meyering <jim@meyering.net>
4441 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4443 * xfns.c (x_window): Use xstrdup (Bug#11375).
4445 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4447 * xdisp.c (pos_visible_p): If already at a newline from the
4448 display string before the 'while' loop, don't walk back the glyphs
4449 from it3.glyph_row. Solves assertion violation when the display
4450 string begins with a newline (egg.el). (Bug#11367)
4452 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4454 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4457 2012-05-01 Glenn Morris <rgm@gnu.org>
4459 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4460 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4461 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4462 All were removed before 23.1.
4464 * dispnew.c: Remove HAVE_LIBNCURSES test;
4465 it is always true on relevant platforms.
4467 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4468 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4470 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4472 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4474 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4475 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4478 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4480 Do not avoid creating empty evaporating overlays (Bug#9642).
4481 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4482 That is, do not delete an evaporating overlay if it becomes
4483 empty after its bounds are adjusted to fit within its buffer.
4484 This fix caused other problems, and I'm reverting it until we get
4485 to the bottom of them.
4487 2012-04-27 Chong Yidong <cyd@gnu.org>
4489 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4491 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4493 * xdisp.c (pos_visible_p): If the window start position is beyond
4494 ZV, start the display from buffer beginning. Prevents assertion
4495 violation in init_iterator when the minibuffer window is scrolled
4498 * window.c (window_scroll_pixel_based): Likewise.
4500 2012-04-27 Chong Yidong <cyd@gnu.org>
4502 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4504 2012-04-27 Glenn Morris <rgm@gnu.org>
4506 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4507 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4509 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4511 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4512 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4514 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4516 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4517 display element, check also the underlying string or buffer
4518 character. (Bug#11341)
4520 * w32menu.c: Include w32heap.h.
4521 (add_menu_item): If the call to AppendMenuW (via
4522 unicode_append_menu) fails, disable Unicode menus only if we are
4523 running on Windows 9X/Me.
4525 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4527 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4528 (xgetint): Add missing shift for LSB tags.
4530 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4532 * keyboard.c (read_char): Don't wipe echo area for select window
4533 events: These might get delayed via `mouse-autoselect-window'
4536 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4538 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4539 manipulation of :loaded-from data.
4541 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4543 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4544 now a cons (bug#11311).
4546 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4548 Do not create empty overlays with the evaporate property (Bug#9642).
4549 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4550 if it becomes empty after its bounds are adjusted to fit within
4551 its buffer. Without this fix, in a nonempty buffer (let ((o
4552 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4553 yields an empty overlay that has the evaporate property, which is
4554 not supposed to happen.
4556 Fix minor GTK3 problems found by static checking.
4557 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4558 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4559 (struct _EmacsFixedClass, emacs_fixed_get_type):

4572 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4574 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4576 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4577 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4578 (__malloc_size_t, __malloc_ptrdiff_t):
4579 Remove. All uses removed, replaced by the definiens if needed,
4580 since we can assume C89 or better now.
4581 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4582 (protect_malloc_state, align, get_contiguous_space)

4591 Define using prototypes, not old style.
4592 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4593 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4594 (align): Don't assume that signed integer overflow wraps around.
4595 Omit unused local var.
4596 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

4658 since the two debugging options are incompatible.
4659 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4661 (mem_init, mem_insert, mem_insert_fixup):
4662 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4671 * sysdep.c [__FreeBSD__]: Minor cleanups.
4672 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4673 Use Emacs indenting style more consistently. Avoid some casts.
4674 Use 'double' consistently rather than mixing 'float' and 'double'.
4676 2012-04-21 Eduard Wiebe <usenet@pusto.de>
4678 * sysdep.c (list_system_processes, system_process_attributes):
4679 Add implementation for FreeBSD (Bug#5243).

4692 * print.c (print_preprocess): Only check print_depth if print-circle
4694 (print_object): Check for cycles even when print-circle is nil and
4695 print-gensym is t, but only check print_depth if print-circle is nil.
4697 2012-04-20 Chong Yidong <cyd@gnu.org>
4699 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4700 set the status to "failed" and ensure that sentinel is run.

4715 farther than the first row after the header line, if any.
4716 Don't consider the header-line row as "partially visible", even if
4717 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

4755 New extern decls, to avoid calling undeclared functions.
4756 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4757 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4758 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4759 (NEED_MEM_INSERT): New macro.
4760 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4761 Remove one incorrect comment and fix another.

4775 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4776 Remove decls. This fixes an "It stinks!".
4778 * alloc.c (which_symbols): Fix alignment issue / type clash.
4780 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4782 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4793 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4795 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4796 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4797 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4798 * s/netbsd.h, s/sol2-6.h:
4799 Remove definition of GC_MARK_STACK, since the default now works.
4800 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4801 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4802 no longer the default.
4803 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4805 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4807 * lread.c (lisp_file_lexically_bound_p):

4828 2012-04-11 Daniel Colascione <dancol@dancol.org>
4830 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4831 against is gone. It's better to use vfork now so that when Cygwin
4832 gains a new, working vfork, we use it automatically (bug#10398).
4834 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4836 * window.c (save_window_save): Obey window-point-insertion-type.

4855 being loaded (bug#10424).
4857 2012-04-09 Glenn Morris <rgm@gnu.org>
4859 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4860 not just in the obarray, before snarfing them. (Bug#11036)
4862 * Makefile.in ($(leimdir)/leim-list.el):
4863 Pass EMACS rather than BUILT_EMACS.
4865 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4867 * process.c (make_process):
4868 * process.h: Add integer `gnutls_handshakes_tried' member to
4871 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4872 Add convenience `GNUTLS_LOG2i' macro.
4874 * gnutls.c (gnutls_log_function2i): Convenience log function.
4875 (emacs_gnutls_read): Use new log functions,
4876 `gnutls_handshakes_tried' process member, and
4877 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4878 attempts per process (connection).
4880 2012-04-09 Chong Yidong <cyd@gnu.org>
4882 * eval.c (Fuser_variable_p, user_variable_p_eh)

4887 * minibuf.c (Fread_variable): Callers changed.
4889 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4891 * xdisp.c (set_cursor_from_row): If the display string appears in
4892 the buffer at position that is closer to point than the position
4893 after the display string, display the cursor on the first glyph of
4894 the display string. Fixes cursor display when a 'display' text
4895 property immediately follows invisible text. (Bug#11094)
4897 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4899 composite.c: use 'double' consistently
4900 * composite.c (get_composition_id): Use 'double' consistently
4901 instead of converting 'float' to 'double' and vice versa; this is
4902 easier to understand and avoids a GCC warning.
4904 2012-04-09 Glenn Morris <rgm@gnu.org>
4906 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4907 preparation for dumping it with emacs. (Bug#4789)
4908 (leimdir): New variable.
4909 ($(leimdir)/leim-list.el): New rule.

4926 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4928 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
4929 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4930 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4931 objects, as mark_maybe_pointer will catch them otherwise.
4932 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4933 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4935 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4937 Fix typo that broke non-Windows builds.
4938 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

4944 * makefile.w32-in (OBJ2): Add xml.$(O).
4945 (GLOBAL_SOURCES): Add xml.c.
4946 ($(BLD)/xml.$(O)): New dependency list.
4948 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
4949 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4950 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4951 [!WINDOWSNT]: New macros.
4952 (init_libxml2_functions, libxml2_loaded_p): New functions.
4953 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4954 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4955 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4956 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4958 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4959 Call init_libxml2_functions before calling libxml2 functions.
4960 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4962 * emacs.c: Don't include libxml/parser.h.
4963 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4964 xmlCleanupParser directly.
4966 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4968 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4970 * indent.c (Fvertical_motion): If there is a display string at
4971 point, use it.vpos to compute how many lines to backtrack after
4972 move_it_to point. (Bug#11133)
4974 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4976 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4977 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4978 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4979 macros related to unification of CJK characters. For the details,
4980 see the discussion following the message here:
4981 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4983 2012-04-04 Chong Yidong <cyd@gnu.org>
4985 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4987 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4989 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4990 instead of alloca. (Bug#11138)
4992 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4994 * w32menu.c (is_simple_dialog): Properly check lisp types.
4997 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4999 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5000 position we get to after a call to move_it_to fails the
5001 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5002 only if we wind up in a string from display property. (Bug#11063)
5004 * window.c (Fdelete_other_windows_internal): Invalidate the row
5005 and column information about mouse highlight, so that redisplay
5006 restores it after reallocating the glyph matrices. (Bug#7464)
5008 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5009 string comes from a `display' text property, use the buffer
5010 position of that property as if we actually saw that position in
5012 (move_it_by_lines): Remove the assertion that
5013 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5014 violated when there's a before-string at the beginning of a line.
5017 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5019 * xdisp.c (append_space_for_newline): If the default face was
5020 remapped, use the remapped face for the appended newline.
5021 (extend_face_to_end_of_line): Use the remapped default face for
5022 extending the face to the end of the line.
5023 (display_line): Call extend_face_to_end_of_line when the default
5024 face was remapped. (Bug#11068)
5026 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5028 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5030 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5032 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5034 2012-03-27 Glenn Morris <rgm@gnu.org>
5036 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5039 2012-03-26 Kenichi Handa <handa@m17n.org>
5041 * dispextern.h (struct glyph): Fix previous change. Change the
5042 bit length of glyphless.ch to 25 (Bug#11082).
5044 2012-03-26 Chong Yidong <cyd@gnu.org>
5046 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5047 (command_loop_1): Use it; inhibit selection update for
5048 handle-select-window too (Bug#8996).
5050 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5052 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5054 2012-03-25 Kenichi Handa <handa@m17n.org>
5056 * dispextern.h (struct glyph): Change the bit length of
5057 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5059 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5061 * s/ms-w32.h (tzname): Include time.h before redirecting to
5062 _tzname. Fixes the MSVC build. (Bug#9960)
5064 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5066 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5069 * xterm.c (XTread_socket): Only modify handling_signal if
5070 !SYNC_INPUT. (Bug#11080)
5072 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5074 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5075 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5076 when fetching a multibyte character consumes more bytes than
5077 CHAR_BYTES returns, due to unification of CJK characters in
5078 string_char. (Bug#11073)
5080 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5082 * process.c (wait_reading_process_output): Handle pty disconnect
5083 by refraining from sending oneself a SIGCHLD (bug#10933).
5085 2012-03-22 Chong Yidong <cyd@gnu.org>
5087 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5089 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5090 Mark string as coming from a prefix property.
5091 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5092 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5094 2012-03-21 Chong Yidong <cyd@gnu.org>
5096 * xfaces.c (Vface_remapping_alist): Doc fix.
5098 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5100 * w32proc.c (Fw32_set_console_codepage)
5101 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5104 2012-03-20 Chong Yidong <cyd@gnu.org>
5106 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5107 to reflect default non-nil value of redisplay-dont-pause.
5109 2012-03-19 Kenichi Handa <handa@m17n.org>
5111 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5112 it fit in a valid range (Bug#11003).
5114 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5116 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5117 that is not from display property, accept the row as a "cursor
5118 row" if one of the string's character has a non-nil `cursor'
5119 property. Fixes cursor positioning when there are newlines in
5120 overlay strings, e.g. in icomplete.el. (Bug#11035)
5122 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5124 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5126 2012-03-12 Chong Yidong <cyd@gnu.org>
5128 * eval.c (inhibit_lisp_code): Rename from
5129 inhibit_window_configuration_change_hook; move from window.c.
5131 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5132 * window.c (run_window_configuration_change_hook)
5133 (syms_of_window): Callers changed.
5135 2012-03-11 Chong Yidong <cyd@gnu.org>

5144 is visible (Bug#10955).
5146 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5148 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5150 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5152 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5153 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5156 2012-03-03 Glenn Morris <rgm@gnu.org>
5158 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5160 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5162 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5163 position past the first glyph_row that ends at ZV. (Bug#10902)
5164 (redisplay_window, next_element_from_string): Fix typos in
5166 (redisplay_window): Pass to move_it_vertically the margin in
5167 pixels, not in screen lines.
5169 2012-03-02 Glenn Morris <rgm@gnu.org>
5171 * buffer.c (buffer-list-update-hook): Doc fix.
5173 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5175 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5176 push_it before setting up the iterator for the first overlay
5177 string, even if we have an empty string loaded.
5178 (next_overlay_string): If there's an empty string on the iterator
5179 stack, pop the stack. (Bug#10903)
5181 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5183 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5184 Suggested by Stefan Monnier in
5185 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5186 * alloc.c (widen_to_Lisp_Object): New static function.
5187 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5188 and widening them to Lisp_Objects. This would work even if
5189 USE_LSB_TAG is defined and wide integers are used, which might
5190 happen in a future version of Emacs.
5192 2012-02-25 Chong Yidong <cyd@gnu.org>
5194 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5197 * xselect.c (Fx_selection_exists_p): Doc fix.
5198 (x_clipboard_manager_save_all): Print an informative message
5199 before saving to clipboard manager.
5201 2012-02-24 Chong Yidong <cyd@gnu.org>
5203 * keyboard.c (process_special_events): Handle all X selection
5204 requests in kbd_buffer, not just the next one (Bug#8869).
5206 2012-02-23 Chong Yidong <cyd@gnu.org>
5208 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5209 call when setting menu-bar-lines and tool-bar-lines parameters.
5210 (unwind_create_frame_1): New helper function.
5212 * window.c (inhibit_window_configuration_change_hook): New var.
5213 (run_window_configuration_change_hook): Obey it.
5214 (syms_of_window): Initialize it.
5216 2012-02-22 Chong Yidong <cyd@gnu.org>

5231 when computing $valmask.
5233 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5234 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5235 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5236 It's useless in that case, and it can cause problems on hosts
5237 that allocate halves of EMACS_INT values separately.
5238 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5239 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5240 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5241 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5242 it avoids undefined behavior on hosts where shifting right by more
5243 than the word width has undefined behavior.
5245 2012-02-19 Chong Yidong <cyd@gnu.org>
5247 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5248 (Funhandled_file_name_directory, Ffile_name_as_directory)

5251 return values (Bug#10845).
5253 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5255 * .gdbinit (pitx): Fix incorrect references to fields of the
5258 2012-02-17 Chong Yidong <cyd@gnu.org>

5265 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5267 2012-02-15 Chong Yidong <cyd@gnu.org>
5269 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5270 marked as special. Also, starting docstrings with * is obsolete.
5272 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

5285 2012-02-12 Chong Yidong <cyd@gnu.org>
5287 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5288 as that creates a dangerous corner case.
5290 * window.c (Fdelete_window_internal): Invalidate the mouse
5291 highlight (Bug#9904).
5293 2012-02-12 Glenn Morris <rgm@gnu.org>
5295 * xselect.c (Fx_own_selection_internal)
5296 (Fx_get_selection_internal, Fx_disown_selection_internal)
5297 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5298 * nsselect.m (Fx_own_selection_internal)
5299 (Fx_disown_selection_internal, Fx_selection_exists_p)
5300 (Fx_selection_owner_p, Fx_get_selection_internal):
5301 Sync docs and argument specs with the xselect.c versions.
5303 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5305 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5307 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5309 * w32select.c (Fx_selection_exists_p): Sync doc string and

5323 2012-02-07 Chong Yidong <cyd@gnu.org>
5325 * buffer.c (Fbuffer_local_variables)
5326 (buffer_lisp_local_variables): Handle unbound vars correctly;
5327 don't let Qunbound leak into Lisp.
5329 2012-02-07 Glenn Morris <rgm@gnu.org>
5331 * image.c (Fimagemagick_types): Doc fix.
5333 * image.c (imagemagick-render-type): Change it from a lisp object
5334 to an integer. Move the doc here from the lisp manual.

5339 * doc.c (store_function_docstring): Avoid applying docstring of
5340 alias to base function (Bug#2603).

5895 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
5896 of scroll runs so as to avoid assigning disabled bogus rows and
5897 unnecessary graphics copy operations.
5899 2011-11-27 Eli Zaretskii <eliz@gnu.org>
5901 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
5902 (snprintf) [_MSC_VER]: Redirect to _snprintf.

5904 (malloc, free, realloc, calloc): Redirect to e_* only when
5907 * lisp.h (GCTYPEBITS): Move before first use.
5908 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
5909 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
5910 this macro definition.
5912 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
5915 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

5933 Indent for consistency with usual Emacs style.
5935 2011-11-25 Eli Zaretskii <eliz@gnu.org>
5937 * xdisp.c (redisplay_window): If cursor row is not fully visible
5938 after recentering, and scroll-conservatively is set to a large
5939 number, scroll window by a few more lines to make the cursor fully
5940 visible and out of scroll-margin. (Bug#10105)
5941 (start_display): Don't move to the next line if the display should
5942 start at a newline that is part of a display vector or an overlay

6024 Problem reported by Andreas Schwab in
6025 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6026 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6027 is set, removing the need for VIRT_ADDRESS_VARIES.
6028 (PURE_P): Use a more-efficient implementation that needs just one
6029 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6030 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6031 to 4 (xorl, subq, cmpq, setbe).
6032 * alloc.c (pure): Always extern now, since that's the
6033 VIRT_ADDR_VARIES behavior.
6034 (PURE_POINTER_P): Use a single comparison, not two, for
6035 consistency with the new puresize.h.
6036 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6037 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6043 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6044 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6045 behave as if the cursor position were at the window margin.
6047 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6048 and the cursor position is out of bounds, behave as if the cursor
6049 position were at the window margin. (Bug#10075)
6051 2011-11-18 Chong Yidong <cyd@gnu.org>
6053 * window.c (Fwindow_combination_limit): Make first argument
6054 non-optional, since it is meaningless for live windows like the

6070 (copy_row_except_pointers): Preserve the used[] arrays and the
6071 hash values of the two rows. (Bug#10035)
6072 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6074 * xdisp.c (row_hash): New function, body extracted from
6075 compute_line_metrics.
6076 (compute_line_metrics): Call row_hash, instead of computing the
6079 * dispnew.c (verify_row_hash): Call row_hash for computing the
6080 hash code of a row, instead of duplicating code from xdisp.c.
6082 * dispextern.h (row_hash): Add prototype.
6084 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6086 * frame.c (delete_frame): Don't delete the terminal when the last
6087 X frame is closed if emacs is built with GTK toolkit.

6110 (Vwindow_nest): Rename to Vwindow_combination_limit.
6111 (recombine_windows, make_parent_window, make_window)
6112 (Fsplit_window_internal, saved_window)
6113 (Fset_window_configuration, save_window_save): Rename all
6114 occurrences of window_nest to window_combination_limit.
6116 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6118 * image.c (imagemagick_load_image): Fix typo.
6120 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6122 * xdisp.c (display_line): Move the call to
6123 highlight_trailing_whitespace before the call to
6124 compute_line_metrics, since the latter needs to see the final
6125 faces of all the glyphs to compute ROW's hash value.
6126 Fixes assertion violations in row_equal_p. (Bug#10035)
6128 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6130 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6135 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6136 with user-defined heap size. Bump the default size of the temacs
6137 heap to 27MB, to avoid memory warning when running temacs.
6138 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6140 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6187 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6189 Avoid some portability problems by eschewing 'extern inline' functions.
6190 The trivial performance wins aren't worth the portability hassles; see
6191 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6193 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6194 (window_box_width, window_box_left, window_box_left_offset)
6195 (window_box_right, window_box_right_offset): Undo previous change,
6196 by removing the "extern"s.
6197 * intervals.c (adjust_intervals_for_insertion)
6198 (adjust_intervals_for_deletion): Undo previous change,
6199 making these static again.
6200 (offset_intervals, temp_set_point_both, temp_set_point)
6201 (copy_intervals_to_string): No longer inline.
6202 * xdisp.c (window_text_bottom_y, window_box_width)

6241 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6242 This is also needed for porting to any host where GC_MARK_STACK is
6243 not GC_MAKE_GCPROS_NOOPS.
6244 (which_symbols): Use it.
6246 2011-11-07 Kenichi Handa <handa@m17n.org>

6259 * xmenu.c (cleanup_widget_value_tree): New function.
6260 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6267 (window_box_width, window_box_left, window_box_left_offset)
6268 (window_box_right, window_box_right_offset): Declare extern.
6269 Otherwise, these inline functions do not conform to C99 and
6270 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6271 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6272 * intervals.c (adjust_intervals_for_insertion)
6273 (adjust_intervals_for_deletion): Now extern, because otherwise the
6274 extern inline functions 'offset_intervals' couldn't refer to it.
6275 (static_offset_intervals): Remove.
6276 (offset_intervals): Rewrite using the old contents of
6277 static_offset_intervals. The old version didn't conform to C99
6278 because an extern inline function contained a reference to an
6279 identifier with static linkage.
6281 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6283 * keyboard.c (interrupt_signal): Don't call kill-emacs while in
6286 2011-11-06 Eli Zaretskii <eliz@gnu.org>

6299 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
6300 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6301 (Fwindow_vscroll): Doc fix.
6302 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6303 argument, since it makes no sense to pass a live window and for
6304 consistency with window-child.

6414 (mouse_face_from_buffer_pos, note_mouse_highlight):
6415 Rename cover_string to disp_string.
6417 2011-11-01 Martin Rudalics <rudalics@gmx.at>

6454 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6456 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6458 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6477 Not clear what it was for, and it causes various bugs. (Bug#9839)
6479 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6481 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6482 possible random value that matches one of those tested as
6483 condition to clear the mouse face.
6485 2011-10-28 Chong Yidong <cyd@gnu.org>
6487 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6507 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6508 (g_b_init_get_glyph_outline_w): New static variables.
6509 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

6511 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6512 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6514 (w32font_open_internal, compute_metrics):
6515 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6516 instead of calling the "wide" APIs directly.
6518 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6520 * w32.h (syms_of_w32font): Add prototype.
6522 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6524 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6525 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6526 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6534 non-NULL, regardless of GNUTLS_INITSTAGE.
6535 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

6556 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6558 * w32fns.c (w32_default_color_map): New function,
6559 extracted from Fw32_default_color_map.
6560 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6562 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6564 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6566 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6568 * keyboard.c (test_undefined): New function (bug#9751).
6569 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6571 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6573 * sysdep.c (init_sys_modes): Fix the check for the controlling
6574 terminal (Bug#6649).
6576 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6578 * dispextern.h (struct bidi_it): New member next_en_type.
6580 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6581 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6582 current character, check also for next_en_type being WEAK_EN.
6583 (bidi_resolve_weak): Don't enter the expensive loop if the current
6584 position is before next_en_pos. Record the bidi type of the first
6585 non-ET, non-BN character we find, in addition to its position.
6586 (bidi_level_of_next_char): Invalidate next_en_type when
6587 next_en_pos is over-stepped.
6589 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6591 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6592 * editfns.c: Rewrite current-time-zone so that it invokes
6593 the equivalent of (format-time-string "%Z") to get the time zone name.
6594 This fixes a bug when the time zone name contains characters that
6595 need converting from the system time locale to Emacs internal format.
6596 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6597 that patch fixed format-time-string to do the conversion, but
6598 I forgot to fix current-time-zone.
6599 (format_time_string): New function, containing most of
6600 what Fformat_time_string used to contain.
6601 (Fformat_time_string): Rewrite in terms of format_time_string.
6602 This doesn't change this function's behavior.
6603 (current-time-zone): Rewrite to use format_time_string.
6604 This fixes the bug reported by Michael Schierl in
6605 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6606 Jason Rumney's 2007-06-07 change worked around this bug, but
6608 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6610 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6612 * xdisp.c (start_display): If the character at POS is displayed
6613 via a display vector, reset IT->current.dpvec_index to zero.
6614 (try_window_reusing_current_matrix): If a line ends in a display
6615 vector or the next line starts in a display vector, continue
6616 redrawing the window even though the character position of
6617 start_row was reached.
6620 2011-10-18 Chong Yidong <cyd@gnu.org>
6622 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6623 with nobreak-char-display too.
6625 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6627 Fix part 3 of bug#9771.
6628 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6629 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6630 non-neutral characters if the current character is a paragraph
6631 separator (a.k.a. Newline). This avoids running the same
6632 expensive loop twice, once when we consume the preceding newline
6633 and the other time when the line actually needs to be displayed.
6634 Avoid the loop when we see neutrals on the base embedding level
6635 following a character whose directionality is the same as the
6636 paragraph's. This avoids running the expensive loop when a line
6637 ends in a long sequence of neutrals, like control characters.
6638 Add assertion against STRONG_AL type. Slightly rearrange code
6639 that determines the type of a neutral given the first non-neutral
6641 (bidi_level_of_next_char): Set next_en_pos to zero when
6642 invalidating its info.
6644 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6646 * xdisp.c (push_display_prop): Determine whether to record string
6647 or buffer position by IT->string, not by IT->method. Allow
6648 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6649 (move_it_vertically_backward): Don't look for character position
6650 immediately after the newline when in a continuation line.
6653 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6655 * window.c (coordinates_in_window): Rewrite and delabelize
6656 vertical border check. (Bug#5357) (Bug#9618)
6658 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6660 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6661 errors in XSetWindowBorder (bug#9310).
6663 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6665 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6666 avoid crash when xmalloc overrun checking is enabled.
6668 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6670 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6671 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6672 cursor motion with <left> and <right> arrow keys.
6674 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6675 some callers set that themselves.
6677 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6679 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6680 display string and the previous row comes from the same string and
6681 is empty. (Bug#9739) (Bug#9738)
6683 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6685 * doc.c (get_doc_string): Encode file name (bug#9735).
6687 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6689 * bidi.c (bidi_level_of_next_char):
6690 * xdisp.c (get_visually_first_element): Remove old incorrect
6691 comments regarding the Unicode Line Separator character.
6693 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6695 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6697 * alloc.c (Fgc_status): Do not access beyond zombies array
6698 boundary if nzombies > MAX_ZOMBIES.
6699 * alloc.c (dump_zombies): Add missing format specifier.
6701 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6703 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6704 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6706 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6707 Some packages use them to denote characters with modifiers.
6709 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6711 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6712 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6713 matching a pp-number. Rename parameter var to var1.
6715 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6717 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6719 2011-10-08 Glenn Morris <rgm@gnu.org>
6721 * callint.c (Fcall_interactively): Give a more explicit error for the
6722 'c' case with a non-character input. (Bug#8479)
6724 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6726 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6728 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6729 lines that are hscrolled on the left.
6731 * dispnew.c (buffer_posn_from_coords): Account for a possible
6732 presence of header-line. (Bug#4426)
6734 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6736 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6737 Don't advertise functionality which we discourage or doesn't work.
6739 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6741 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6742 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6743 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6744 this makes Emacs dump core during garbage collection on rare
6745 occasions. sizeof is obviously inferior to offsetof here, so
6746 stick with offsetof.
6747 (GC_POINTER_ALIGNMENT): New macro.
6748 (mark_memory): Omit 3rd (offset) arg; caller changed.
6749 Don't assume EMACS_INT alignment is the same as pointer alignment.
6751 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6753 * keyboard.c (read_key_sequence_remapped): New var.
6754 (read_key_sequence): Compute remapping in the right buffer.
6755 (command_loop_1): Use read_key_sequence's remapping directly.
6757 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6759 * dired.c (file_name_completion): Don't expand file name.
6760 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6761 before checking file name handler.
6763 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6764 they've been requested explicitly (bug#9591).
6766 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6768 * keymap.c (Fsingle_key_description): Use make_specified_string
6769 instead of build_string to build string from push_key_description.
6772 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6774 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6775 This fixes a Y2038 bug on 64-bit hosts.
6776 * buffer.c (reset_buffer):
6777 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6778 (Fclear_buffer_auto_save_failure):
6779 Use 0, not -1, to represent an unset failure time, since time_t
6780 might not be signed.
6782 Remove dependency on glibc malloc internals.
6783 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6784 Move back here from lisp.h, but with their new implementations.
6785 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6786 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6787 * charset.c (charset_table_init): New static var.
6788 (syms_of_charset): Use it instead of xmalloc. This removes a
6789 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6790 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6791 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6792 Move back to alloc.c.
6793 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6794 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6796 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6798 * nsterm.m (windowDidResize): Call x_set_window_size only when
6799 ns_in_resize is true. Otherwise set pixelwidth/height and
6800 call change_frame_size (Bug#9628).
6802 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6804 Port --enable-checking=all to Fedora 14 x86-64.
6805 * charset.c (syms_of_charset): Also account for glibc malloc's
6806 internal overhead when calculating the initial malloc maximum.
6808 Port --enable-checking=all to Fedora 14 x86.
6809 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6811 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6812 (overrun_check_realloc, overrun_check_free):
6813 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6814 That way, xmalloc returns a properly-aligned pointer even if
6815 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6816 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6817 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6818 into account when calculating the initial malloc maximum.
6819 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6820 Move here from alloc.c, so that charset.c can use it too.
6821 Properly align; the old code wasn't right for common 32-bit hosts
6822 when configured with --enable-checking=all.
6823 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6824 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6826 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6828 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6831 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6833 * xdisp.c (compute_display_string_end): If there's no display
6834 string at CHARPOS, return -1.
6836 * bidi.c (bidi_fetch_char): When compute_display_string_end
6837 returns a negative value, treat the character as a normal
6838 character not covered by a display string. (Bug#9624)
6840 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6842 * lread.c (Fread_from_string): Fix typo in docstring.
6844 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6846 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6847 newline, reseat the iterator instead of bidi-iterating there one
6848 character at a time. (Bug#9610)
6849 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6850 TO_CHARPOS if the bidi iterator is at base embedding level.
6852 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6854 * lread.c (readevalloop): Use correct code for NBSP.
6855 (read1): Likewise. (Bug#9608)
6857 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6859 * dbusbind.c (Fdbus_register_signal): When service is not
6860 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6862 2011-09-25 Glenn Morris <rgm@gnu.org>
6864 * buffer.c (truncate-lines): Doc fix.
6866 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6868 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6869 (Fset_window_next_buffers): Doc fix.
6871 2011-09-24 Glenn Morris <rgm@gnu.org>
6873 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6875 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6877 Fix minor problems found by static checking.
6878 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6879 * indent.c (Fvertical_motion): Fix == vs = typo.
6881 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6883 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6884 Default value is now t. Doc fix.
6886 * indent.c (Fvertical_motion): Compute and apply the overshoot
6887 logic when moving up, not only when moving down. Fix the
6888 confusing name and values of the it_overshoot_expected variable;
6889 logic changes accordingly. (Bug#9254) (Bug#9549)
6891 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6892 CHARPOS is covered by a display string which includes newlines.
6893 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6894 is covered by a display string with embedded newlines.
6896 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6898 * dbusbind.c (Fdbus_register_signal): Add match rule to
6899 Vdbus_registered_objects_table. (Bug#9581)
6900 (Fdbus_register_method, Vdbus_registered_objects_table):
6903 2011-09-24 Jim Meyering <meyering@redhat.com>
6905 do not ignore write error for any output size
6906 The previous change was incomplete.
6907 While it makes emacs --batch detect the vast majority of stdout
6908 write failures, errors were still ignored whenever the output size is
6909 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6910 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6911 && echo FAIL: ignored write error
6912 FAIL: ignored write error
6913 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6914 && echo FAIL: ignored write error
6915 FAIL: ignored write error
6916 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6918 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6920 * emacs.c (Fkill_emacs): In noninteractive mode exit
6921 non-successfully if a write error occurred on stdout. (Bug#9574)
6923 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6925 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6928 * dispextern.h (struct it): Update the comment documenting what
6931 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6933 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6934 a display string, extend search for cursor position to end of row.
6935 (find_row_edges): If the row ends in a newline from a display
6936 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6937 Handle the case of a display string with multiple newlines.
6938 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6939 non-empty line. Fixes confusing cursor motion with arrow keys at
6940 the beginning of a line that starts with whitespace.
6942 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6944 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6947 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6949 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6952 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6954 * xdisp.c (display_line): Record maximum and minimum buffer
6955 positions even if no glyphs were produced (e.g., by a zero-width
6956 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6957 buffer positions that will be removed from the glyph row because
6959 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6960 column is beyond frame width: don't subtract 1 "pixel" when
6961 computing width of the stretch.
6962 (reseat_at_next_visible_line_start): Undo the change made on
6963 2011-09-17 that saved paragraph information and restored it after
6964 the call to `reseat'. (Bug#9545)
6966 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6968 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6969 and turn window cursor on if cleared (Bug#9415).
6971 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6973 * search.c (boyer_moore): Take unibyte characters from pattern
6974 literally. (Bug#9458)
6976 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6978 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6980 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6982 Fix minor problem found by static checking.
6983 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6984 initialized, to pacify gcc -Wuninitialized.
6986 * fileio.c: Report proper errno when syscall falls.
6987 (Finsert_file_contents): Save and restore errno,
6988 so that report_file_error outputs the correct diagnostic.
6989 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6991 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6993 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6995 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6997 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6998 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7000 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7002 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7003 about the current paragraph and restore it after the call to reseat.
7005 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7006 (bidi_find_paragraph_start): Search back for paragraph beginning
7007 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7008 (bidi_move_to_visually_next): Only trigger paragraph-related
7009 computations when the last character is a newline or at EOB, not
7010 just any NEUTRAL_B. (Bug#9470)
7012 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7013 truncated lines if point is covered by a display string. (Bug#9524)
7015 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7017 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7018 (cons_to_x_long): New function.
7019 (lisp_data_to_selection_data): Use it. Correct the test for
7020 short-versus-long data; it was negated. Break out of vector
7021 loop, for efficiency, when a long datum is discovered.
7023 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7025 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7027 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7029 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7030 GCC PR/17406) by declaring this function with external scope.
7032 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7034 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7035 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7037 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7039 * editfns.c (Fformat): Correctly handle text properties on "%%".

7049 of TAB characters in a composition.
7051 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7053 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7054 This occurs when processing a multibyte format.
7055 Problem reported by Wolfgang Jenker.
7057 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7059 * xdisp.c (try_cursor_movement): Only check for exact match if
7060 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7062 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7064 Remove unused external symbols.
7065 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7066 * xdisp.c (calc_pixel_width_or_height): Now static.
7067 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7068 * indent.c (check_display_width):
7069 * w32term.c: Fix comment to match code.
7070 * xterm.c, xterm.h (x_catching_errors): Remove.
7072 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7074 * xselect.c: Use signed conversions more consistently (Bug#9498).
7075 (selection_data_to_lisp_data): Assume incoming selection data are
7076 signed integers, not unsigned. This is to be consistent with
7077 outgoing selection data, which was modified to use signed integers
7078 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7079 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7080 expects long, not unsigned long.
7082 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7084 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7085 computation of loop end. Reported by Johan Bockgård
7088 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7090 * frame.c (Fother_visible_frames_p): Function deleted.
7092 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7094 * indent.c (compute_motion): Process display vector front to back
7095 rather than the other way around. (Bug#2496)
7097 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7099 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7101 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7103 * minibuf.c (Fread_from_minibuffer): Doc fix.
7105 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7107 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7108 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7110 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7112 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7113 value for non-existent files.
7115 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7117 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7118 set its "size" to -1. This will set the modtime_size field of
7119 the corresponding buffer to -1, which is what
7120 verify-visited-file-modtime expects for files that do not exist.
7123 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7125 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7127 * lisp.h: ... from here. push_key_description is no longer
7128 defined in keyboard.c, so its declaration should not be in
7129 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7130 logically belongs with push_key_description.
7132 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7134 * buffer.h: Include <sys/types.h> instead of <time.h>.
7135 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7136 Problem reported by Herbert J. Skuhra.
7138 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7140 * xml.c (parse_region): Make the parsing work for
7141 non-comment-starting XML files again (bug#9144).
7143 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7145 * image.c (gif_load): Fix calculation of bottom and right corner.
7148 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7150 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7151 redisplay in small windows.
7153 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7155 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7157 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7159 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7160 Operate on live windows only.
7162 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7164 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7166 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7168 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7169 only under bidi iteration.
7171 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7173 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7175 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7177 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7178 Without this fix, the command to link temacs failed due to an
7179 undefined symbol __builtin_isnan. This is because
7180 /usr/include/iso/math_c99.h #defines isnan(x) to
7181 __builtin_isnan(x), but the bundled gcc, which identifies itself
7182 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7184 * floatfns.c (isnan): #undef, and then #define to a clone of
7186 (Fisnan): Always define, since it's always available now.
7187 (syms_of_floatfns): Always define isnan at the Lisp level.
7189 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7191 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7193 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7195 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7196 The previous code assumed that file offsets (off_t values) fit in
7197 EMACS_INT variables, which is not true on typical 32-bit hosts.
7198 The code messed up by falsely reporting buffer overflow in cases
7199 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7200 when "big" contains more than 2**29 bytes, even though this
7201 inserts just one byte and does not overflow the buffer.
7202 (Finsert_file_contents): Store file offsets as off_t
7203 values, not as EMACS_INT values. Check for overflow when
7204 converting between EMACS_INT and off_t. When checking for
7205 buffer overflow or for overlap, take the offsets into account.
7206 Don't use EMACS_INT for small values where int suffices.
7207 When checking for overlap, fix a typo: ZV was used where
7208 ZV_BYTE was intended.
7209 (Fwrite_region): Don't assume off_t fits into 'long'.
7210 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7212 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7214 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7216 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7218 sprintf-related integer and memory overflow issues (Bug#9412).
7220 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7221 (esprintf, exprintf, evxprintf): New functions.
7222 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7223 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7224 (modify_event_symbol): Do not assume that the length of
7225 name_alist_or_stem is safe to alloca and fits in int.
7226 (Fexecute_extended_command): Likewise for function name and binding.
7227 (Frecursion_depth): Wrap around reliably on integer overflow.
7228 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7229 since some callers pass EMACS_INT values.
7230 (Fsingle_key_description): Don't crash if symbol name contains more
7231 than MAX_ALLOCA bytes.
7232 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7233 (get_minibuffer): Arg is now EMACS_INT, not int.
7234 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7235 (esprintf, exprintf, evxprintf): New decls.
7236 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7238 * dbusbind.c (signature_cat): New function.
7239 (xd_signature, Fdbus_register_signal):
7240 Do not overrun buffer; instead, report string overflow.
7242 * dispnew.c (add_window_display_history): Don't overrun buffer.
7243 Truncate instead; this is OK since it's just a log.
7245 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7246 even if the time zone offset is outlandishly large.
7247 Don't mishandle offset == INT_MIN.
7249 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7250 when creating daemon; the previous buffer-overflow check was incorrect.
7252 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7253 which has the guts of the old verror function.
7255 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7256 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7258 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7259 (font_unparse_xlfd): Don't blindly alloca long strings.
7260 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7261 fits in int, when using sprintf. Use single snprintf to count
7262 length of string rather than counting it via multiple sprintfs;
7263 that's simpler and more reliable.
7264 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7265 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7266 sprintf, in case result does not fit in int.
7268 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7269 (fontset_from_font): Print it.
7271 * frame.c (tty_frame_count): Now printmax_t, not int.
7272 (make_terminal_frame, set_term_frame_name): Print it.
7273 (x_report_frame_params): In X, window IDs are unsigned long,
7274 not signed long, so print them as unsigned.
7275 (validate_x_resource_name): Check for implausibly long names,
7276 and don't assume name length fits in 'int'.
7277 (x_get_resource_string): Don't blindly alloca invocation name;
7278 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7281 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7282 (xg_check_special_colors, xg_set_geometry):
7283 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7285 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7286 Use esprintf, not sprintf, in case result does not fit in int.
7288 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7289 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7290 it as a large positive number.
7291 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7292 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7294 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7295 in case result does not fit in int.
7297 * print.c (float_to_string): Detect width overflow more reliably.
7298 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7299 buffer overrun. Don't assume list length fits in 'int'. Treat
7300 print length of 0 as 0, not as infinity; to be consistent with other
7301 uses of print length in this function. Don't overflow print length
7302 index. Don't assume hash table size fits in 'long', or that
7303 vectorlike size fits in 'unsigned long'.
7305 * process.c (make_process): Use printmax_t, not int, to format
7306 process-name gensyms.
7308 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7310 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7311 to avoid potential buffer overrun.
7313 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7314 if X resource line is longer than 512 bytes.
7316 * xfns.c (x_window): Make sprintf buffer a bit bigger
7317 to avoid potential buffer overrun.
7319 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7323 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7325 Integer overflow fixes for scrolling, etc.
7326 Without these, Emacs silently mishandles large integers sometimes.
7327 For example, "C-u 4294967297 M-x recenter" was treated as if
7328 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7330 * xdisp.c (try_window_id): Check Emacs fixnum range before
7331 converting to 'int'.
7333 * window.c (window_scroll_line_based, Frecenter):
7334 Check that an Emacs fixnum is in range before assigning it to 'int'.
7335 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7336 values converted from Emacs fixnums.
7337 (Frecenter): Don't wrap around a line count if it is out of 'int'
7338 range; instead, treat it as an extreme value.
7339 (Fset_window_configuration, compare_window_configurations):
7340 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7342 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7343 that can exceed INT_MAX. Check that EMACS_INT value is in range
7344 before assigning it to the (possibly-narrower) index.
7345 (match_limit): Don't assume that a fixnum can fit in 'int'.
7347 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7350 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7351 (Fvertical_motion): Don't wrap around LINES values that don't fit
7352 in 'int'. Instead, treat them as extreme values. This is good
7353 enough for windows, which can't have more than INT_MAX lines anyway.
7355 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7357 * Require libxml/parser.h to avoid compilation warning.
7359 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7361 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7362 since this reportedly can destroy thread storage.
7364 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7366 * syntax.c (find_defun_start): Update all cache variables if
7367 exiting early (Bug#9401).
7369 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7371 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7373 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7374 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7375 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7377 * term.c (tty_append_glyph): New function.
7378 (produce_stretch_glyph): Static function and its prototype deleted.
7380 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7383 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7385 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7386 when checking :margin (Bug#9390).
7387 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7388 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7389 so that the name doesn't mislead. All uses changed.
7391 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7393 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7396 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7398 * xdisp.c (move_it_to): Don't bail out early when reaching
7399 position beyond to_charpos, if we are scanning backwards.
7400 (move_it_vertically_backward): When DY == 0, make sure we get to
7401 the first character in the line after the newline.
7403 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7405 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7406 (ccl_driver): Do not generate an out-of-range pointer.
7407 (Fccl_execute_on_string): Remove unnecessary check for
7408 integer overflow, noted by Stefan Monnier in
7409 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7410 Remove a FIXME that didn't need fixing.
7411 Simplify the newly-introduced buffer reallocation code.
7413 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7415 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7417 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7419 Integer and memory overflow issues (Bug#9196).
7421 * doc.c (get_doc_string): Rework so that
7422 get_doc_string_buffer_size is the actual buffer size, rather than
7423 being 1 less than the actual buffer size; this makes xpalloc more
7426 * image.c (x_allocate_bitmap_record, cache_image):
7427 * xselect.c (Fx_register_dnd_atom):
7428 Simplify previous changes by using xpalloc.
7430 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7431 since either will do and ptrdiff_t is convenient with xpalloc.
7433 * charset.c (charset_table_size)
7434 (struct charset_sort_data.priority): Now ptrdiff_t.
7435 (charset_compare): Don't overflow if priorities differ greatly.
7436 (Fsort_charsets): Don't assume list length fits in int.
7437 Check for size-calculation overflow when allocating sort data.
7438 (syms_of_charset): Allocate an initial charset table that is
7439 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7441 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7443 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7444 The actual value is always <= INT_MAX, and leaving it unsigned made
7445 overflow checking harder.
7447 * dispextern.h (struct glyph_matrix.rows_allocated)
7448 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7449 with xpalloc. The values are still always <= INT_MAX.
7451 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7453 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7454 (SAFE_NALLOCA): New macro.
7456 * region-cache.c (struct boundary.pos, find_cache_boundary)
7457 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7458 (set_cache_region, invalidate_region_cache)
7459 (revalidate_region_cache, know_region_cache, region_cache_forward)
7460 (region_cache_backward, pp_cache):
7461 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7462 so that ptrdiff_t * can be passed to xpalloc.
7463 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7464 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7465 (pp_cache): Don't assume cache_len fits in int.
7466 * region-cache.h: Adjust extern decls to match.
7468 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7469 EMACS_INT, since either will do, for xpalloc.
7471 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7472 (xnmalloc, xnrealloc, xpalloc): New functions.
7474 * bidi.c (bidi_shelve_header_size): New constant.
7475 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7476 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7478 * bidi.c (bidi_cache_shrink):
7479 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7481 Don't update size of array until after memory allocation succeeds,
7482 because xmalloc/xrealloc may not return.
7483 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7484 now that we have proper integer overflow checking.
7485 (record_overlay_string, overlay_strings): Catch overflows when
7486 calculating size of overlay_str_buf.
7488 * callproc.c (Fcall_process): Check for size overflow when
7489 calculating size of args2.
7490 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7491 Normally we prefer signed values, but sticking with ptrdiff_t would
7492 require adding more-complicated checks.
7494 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7495 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7496 Redo buffer-overflow calculations to avoid integer overflow.
7497 Add a FIXME comment where memory seems to be over-allocated.
7499 * character.c (Fstring): Check for size-calculation overflow.
7501 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7502 unnecessary integer overflow. Check for size overflow.
7503 (encode_coding_object): Don't update size until xmalloc succeeds.
7505 * composite.c (get_composition_id): Check for overflow in glyph
7506 length calculations.
7508 Integer and memory overflow fixes for display code.
7509 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7510 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7511 (scrolling_window): Check for overflow in size calculations.
7512 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7524 (get_doc_string): Check for size calculation overflow.
7525 Don't update size until allocation succeeds.
7526 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7527 EMACS_INT, where ptrdiff_t will do.
7528 (Fsubstitute_command_keys): Check for string overflow.
7530 * editfns.c (set_time_zone_rule): Don't assume environment length
7532 (message_length): Now ptrdiff_t, not int.
7533 (Fmessage_box): Don't update size until allocation succeeds.
7534 Don't assume message length fits in int.
7535 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7537 * emacs.c (main): Do not reallocate argv, since there is a null at
7538 the end that can be overwritten, and this way there's no need to
7539 worry about size-calculation overflow.
7540 (sort_args): Check for size-calculation overflow.
7542 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7544 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7546 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7547 (x_set_scroll_bar_width, x_figure_window_size):
7548 Check for integer overflow.
7549 (x_set_alpha): Do not assume XINT fits in int.
7551 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7552 This is for the members text_lines, text_cols, total_lines, total_cols,
7553 where the system imposes an 'int' limit.
7555 * fringe.c (Fdefine_fringe_bitmap):
7556 Don't update size until alloc works.
7558 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7559 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7561 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7562 Check for size-calculation overflow.
7563 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7564 do, as we prefer signed integers.
7565 (id_to_widget.max_size, id_to_widget.used)
7566 (xg_store_widget_in_map, xg_remove_widget_from_map)
7567 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7568 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7569 Use and return ptrdiff_t, not int.
7570 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7571 * gtkutil.h: Change prototypes to match the above.
7573 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7574 are duplicate now that they've been promoted to lisp.h.
7575 (x_allocate_bitmap_record, x_alloc_image_color)
7576 (make_image_cache, cache_image, xpm_load):
7577 Don't update size until alloc is done.
7578 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7580 Check for size calculation overflow.
7581 (ct_colors_allocated_max): New constant.
7582 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

7587 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7588 Use ptrdiff_t, not int, to count maps.
7589 (read_char_minibuf_menu_prompt): Check for overflow in size
7590 calculations. Don't update size until allocation succeeds.

7602 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7604 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7605 Now ptrdiff_t, not int.
7606 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

7617 * search.c (Freplace_match): Check for size calculation overflow.
7618 (Fset_match_data): Don't assume list lengths fit in 'int'.
7620 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7621 for command line length. Do not attempt to address one before the
7622 beginning of an array, as that's not portable.

7625 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7627 (encode_terminal_code, calculate_costs): Check for size
7628 calculation overflow.

7630 table lengths and related sizes. Don't update size until alloc
7631 done. Redo calculations to avoid overflow.
7632 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7634 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7650 Use ptrdiff_t, not int, for sizes.
7651 (Finternal_make_lisp_face, cache_face):
7652 Check for size calculation overflow.
7653 (cache_face): Treat size calculation overflows as if they were
7654 memory exhaustion (the usual treatment), rather than aborting.
7656 * xfns.c (x_encode_text, x_set_name_internal)
7657 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7658 sizes, since they can exceed INT_MAX in size. Check for size
7659 calculation overflow.
7661 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
7662 (xg_select): Check for size calculation overflow.
7663 Don't update size until alloc done.
7665 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7666 as sprintf is limited to int lengths.
7668 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7669 (X_LONG_MIN): New macros.
7670 Use them to make the following changes clearer.
7671 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7672 This change doesn't affect the value now, but it may help remind
7673 future maintainers not to raise the value too much later.
7674 (SELECTION_QUANTUM): Remove, replacing with ...
7675 (selection_quantum): ... new function, which avoids overflow.
7677 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7678 assumption that selection length fits in 'int'.
7679 (x_reply_selection_request, x_handle_selection_request)
7680 (x_get_window_property, receive_incremental_selection)
7681 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7682 (lisp_data_to_selection_data, clean_local_selection_data):

7684 (x_reply_selection_request, x_get_window_property)
7685 (receive_incremental_selection, x_property_data_to_lisp):
7686 Redo calculations to avoid overflow.
7687 (x_reply_selection_request): When sending hint, ceiling it at
7688 X_LONG_MAX rather than relying on wraparound overflow to send
7690 (x_get_window_property, receive_incremental_selection)
7691 (lisp_data_to_selection_data, x_property_data_to_lisp):
7692 Check for size-calculation overflow.
7693 (x_get_window_property, receive_incremental_selection)

7695 Don't store size until memory allocation succeeds.
7696 (x_get_window_property): Plug memory leak on memory exhaustion.
7697 Don't double-block input; malloc is safe here. Don't assume 2**34
7698 - 4 fits in unsigned long. Add an xassert to check
7699 XGetWindowProperty overflow. Be more careful about overflow
7700 calculations, and distinguish size from memory overflow better.
7701 (receive_incremental_selection): When tracing, don't assume
7702 unsigned int is less than INT_MAX.
7703 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7704 harmful) conversions of unsigned short to int.
7705 (lisp_data_to_selection_data): Don't assume that integers
7706 in the range -65535 through -1 fit in an X unsigned short.
7707 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7708 result parameters unless successful. Rely on cons_to_unsigned
7709 to report problems with elements; the old code wasn't right anyway.
7710 (x_check_property_data): Check for int overflow; we cannot use
7711 a wider type due to X limits.
7712 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7744 * lisp.h (hash_lookup, hash_put):
7745 * minibuf.c (Ftest_completion):
7746 Use ptrdiff_t for hash table indexes, not int (which is too
7747 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7748 32-bit --with-wide-int hosts).
7750 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7751 Add a FIXME comment about memory leaks.
7752 (syms_of_charset): Don't assume xmalloc returns.
7754 Don't assume that stated character widths fit in int.

7759 with outlandish widths.
7760 * character.h (sanitize_tab_width): Rename from sanitize_width,
7761 now that we have two such functions. All uses changed.
7762 (sanitize_char_width): New inline function.

7780 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7781 (x_send_scroll_bar_event): Likewise. Check that the size does not
7782 exceed limits imposed by XClientMessageEvent, as well as the usual
7783 ptrdiff_t and size_t limits.
7785 * keyboard.c: Overflow, signedness and related fixes.
7786 (make_lispy_movement): Use same integer type in forward decl
7787 that is used in the definition.
7788 (read_key_sequence, keyremap_step):
7789 Change bufsize argument back to int, undoing my 2011-03-30 change.
7790 We prefer signed types, and int is wide enough here.
7791 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7792 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7793 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7794 length, not size_t. Use ptrdiff_t for index, not int.
7795 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7796 possibility of integer overflow.
7798 Overflow, signedness and related fixes for images.

7819 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7820 (lookup_image): Remove unnecessary tests.
7821 (xbm_image_p): Locals are now of int, not EMACS_INT,
7822 since parse_image_check makes sure they fit into int.
7823 (png_load, gif_load, svg_load_image):
7824 Prefer int to unsigned where either will do.
7825 (tiff_handler): New function, combining the cores of the
7826 old tiff_error_handler and tiff_warning_handler.
7827 This function is rewritten to use vsnprintf and thereby avoid
7828 stack buffer overflows. It uses only the features of vsnprintf
7829 that are common to both POSIX and native Microsoft.
7830 (tiff_error_handler, tiff_warning_handler): Use it.
7831 (tiff_load, gif_load, imagemagick_load_image):
7832 Don't assume :index value fits in 'int'.
7833 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7834 (imagemagick_load_image): Check that crop parameters fit into
7835 the integer types that MagickCropImage accepts. Don't assume
7836 Vimagemagick_render_type has a nonnegative value. Don't assume
7837 size_t fits in 'long'.
7838 (gs_load): Use printmax_t to print the widest integers possible.

7849 the display spec is of the form `(space ...)'.
7850 (handle_display_spec): Return the value returned by
7851 handle_single_display_spec, not just 1 or zero.
7852 (handle_single_display_spec): If the display spec is of the form
7853 `(space ...)', and specifies display in the text area, return 2
7855 (try_cursor_movement): Check for the need to scroll more
7856 accurately, and prefer exact match for point under bidi.
7857 Don't advance `row' beyond the last row of the window.
7859 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7860 into disp_prop; all users changed.
7862 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

7875 buffers, return left-to-right.
7876 (set_cursor_from_row): Consider candidate row a win if its glyph
7877 represents a newline and point is on that newline. Fixes cursor
7878 positioning on the newline at EOL of R2L text within L2R
7879 paragraph, and vice versa.
7880 (try_cursor_movement): Check continued rows, in addition to
7881 continuation rows. Fixes unwarranted scroll when point enters a
7882 continued line of R2L text within an L2R paragraph, or vice versa.
7883 (cursor_row_p): Consider the case of point being equal to
7884 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7885 from the end of a short line to the beginning of a continued line
7886 of R2L text within L2R paragraph.
7887 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7888 composed characters.
7890 * bidi.c (bidi_check_type): Use xassert.

7903 2011-08-22 Kenichi Handa <handa@m17n.org>
7905 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7906 extra slot even if the purpose is char-code-property-table.
7908 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7910 * xdisp.c (redisplay_window): When computing centering_position,
7911 account for the height of the header line. (Bug#8874)
7913 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7914 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7915 candidate is selected by the mouse, and that candidate has a
7916 composed character under the mouse.
7918 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7919 coordinates reported by pos-visible-in-window-p for a composed
7920 character in column zero.

7926 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7928 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7929 consider it a hit if to_charpos is anywhere in the range of the
7930 composed buffer positions.
7932 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7934 * image.c (gif_load): Don't assume that each subimage has the same
7935 dimensions as the base image. Handle disposal method that is
7936 "undefined" by the gif spec (Bug#9335).
7938 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7940 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

7943 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7945 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7946 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7947 from an Org mode buffer to a Speedbar frame.
7949 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7950 a composition, take its buffer position from IT->cmp_it.charpos.
7951 Fixes cursor positioning at the beginning of a line that begins
7952 with a composed character.
7954 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7956 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7957 character bidirectional type, use STRONG_L instead. Fixes crashes
7958 in a buffer produced by `describe-categories'.
7960 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7961 members before the level stack, so they would be saved and
7962 restored when copying iterator state. Fixes incorrect reordering
7963 around TABs covered by display properties.
7965 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7967 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7975 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7977 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7978 has no `load' handler, try opening the file locally. (Bug#9311)

8039 ppos_it. Fixes vertical cursor motion when line beginning is
8040 covered by an image. (Bug#9296)
8042 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8044 * nsterm.h (ns_run_ascript): Declare.

8048 (ns_run_ascript): New function.
8049 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8050 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8051 the event loop. Get status from as_status (Bug#7276).
8053 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8054 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8055 the event loop (Bug#7276).

8081 (Fnetwork_interface_list): Allocate in increments of bytes instead
8082 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8083 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8085 (struct ifflag_def): notrailers is smart on OSX.
8086 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8087 Get hardware address with getifaddrs if available.
8089 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8091 * xdisp.c (iterate_out_of_display_property): xassert that
8092 IT->position is set to within IT->object's boundaries. Break from
8093 the loop as soon as EOB is reached; avoids infloops in redisplay
8094 when IT->position is set up wrongly due to some bug.
8095 Set IT->current to match the bidi iterator unconditionally.
8096 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8097 entry. Force push_it to save on the stack the current
8098 buffer/string position, to be restored by pop_it. Fix flags in
8099 the iterator structure wrt the object coming from a display
8100 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8101 properties. (Bug#9284)
8103 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8105 * fontset.c (fontset_get_font_group): Add proper type checks.

8113 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8115 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8117 * xdisp.c (forward_to_next_line_start): Allow to use the
8118 no-display-properties-and-no-overlays under bidi display.
8119 Set disp_pos in the bidi iterator to avoid searches for display
8120 properties and overlays.
8122 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8124 * editfns.c (Fset_time_zone_rule): Document relationship with the

8133 restore_point_unwind (Bug#5984).
8135 2011-08-07 Juri Linkov <juri@jurta.org>
8137 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8138 to show the arg `TIME' instead of `TIMEVAL'.
8140 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8142 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a

8144 longlines-mode. (Bug#9254)
8145 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8146 word-wrap under bidirectional display. (Bug#9224)
8148 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8149 is non-zero, even if the data buffer is NULL. Fixes a crash in
8150 vertical-motion with longlines-mode. (Bug#9254)
8152 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8154 * bidi.c <bidi_cache_total_alloc>: Now static.

8157 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8160 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8161 amount allocated this far in `bidi_cache_total_alloc'.
8162 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8163 non-zero, only free the data buffer without restoring the cache
8164 contents. All callers changed.
8166 * dispextern.h (bidi_unshelve_cache): Update prototype.
8168 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8169 (move_it_in_display_line, move_it_to)
8170 (move_it_vertically_backward, move_it_by_lines): Replace the call
8171 to xfree to an equivalent call to bidi_unshelve_cache.
8172 (move_it_in_display_line_to): Fix logic of returning
8173 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8175 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8177 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8178 came from a string character with a `cursor' property. (Bug#9229)

8199 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8201 * callproc.c (Fcall_process): Avoid vfork clobbering
8202 the local vars buffer, coding_systems, current_dir.
8204 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8206 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8208 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8210 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8211 so that it is not optimized away.
8213 * xdisp.c (compute_display_string_pos): Remove unused local.
8215 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8217 Fix slow cursor motion and scrolling in large buffers with
8218 selective display, like Org Mode buffers. (Bug#9218)
8220 * dispextern.h (struct bidi_it): New member disp_prop_p.
8222 * xdisp.c: Remove one-slot cache of display string positions.
8223 (compute_display_string_pos): Accept an additional argument
8224 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8225 for a display string or property. If found, set DISP_PROP_P
8228 * bidi.c (bidi_fetch_char): Accept an additional argument
8229 DISP_PROP_P, and pass it to compute_display_string_pos.
8230 Only handle text covered by a display string if DISP_PROP_P is returned
8231 non-zero. All callers of bidi_fetch_char changed.
8233 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8235 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8237 2010-12-03 Don March <don@ohspite.net>
8239 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8240 last character M-[char] is translated to ESC [char] (bug#7541).
8242 2011-08-02 Kenichi Handa <handa@m17n.org>
8244 * lisp.h (uniprop_table): Extern it.
8246 * chartab.c (uniprop_table): Make it non-static.
8248 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8250 * xdisp.c (forward_to_next_line_start): Accept additional argument
8251 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8253 (reseat_at_next_visible_line_start): Use the bidi iterator state
8254 returned by forward_to_next_line_start to restore the state of
8255 it->bidi_it after backing up to previous newline. (Bug#9212)
8257 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8259 * regex.c (re_comp): Protoize.
8260 (re_exec): Fix return type.
8261 (regexec): Fix type of `ret'. (Bug#9203)
8263 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8265 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8266 This is needed if max-image-size is a floating-point number.
8268 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8270 * print.c (print_object): Print empty symbol as ##.
8272 * lread.c (read1): Read ## as empty symbol.
8274 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8276 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8277 setting frame foreground color (Bug#9175).
8278 (x_set_background_color): Likewise.
8280 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8281 contents (Bug#9176).
8282 (EmacsTooltip -init): Remove bezels and add shadows to
8285 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8286 or scroll bar (Bug#8470).
8288 * nsfont.m (nsfont_open): Remove assignment to voffset and
8289 unnecessary vars hshink, expand, hd, full_height, min_height.
8290 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8292 * nsterm.h (nsfont_info): Remove voffset field.
8294 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8296 Implement strike-through and overline on NextStep (Bug#8863).
8298 * nsfont.m (nsfont_open): Use underline position provided by font,
8299 instead of hard-coded value of 2.
8300 (nsfont_draw): Call ns_draw_text_decoration instead.
8302 * nsterm.h: Add declaration for ns_draw_text_decoration.
8304 * nsterm.m (ns_draw_text_decoration): New function for drawing
8305 underline, overline, and strike-through.
8306 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8307 ns_draw_text_decoration. Change treatment of cursor drawing to
8308 accommodate underlining, etc.
8310 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8312 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8315 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8317 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8318 Without this fix, if a signal arrives just after memory fills up,
8319 'malloc' might be invoked reentrantly.
8321 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8322 In other words, assume that every image size is allowed, on non-X
8323 hosts. This assumption is probably wrong, but it lets Emacs compile.
8325 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8327 * regex.c (re_iswctype): Convert return values to boolean.
8329 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8331 * xdisp.c (compute_display_string_pos): Don't use cached display
8332 string position if the buffer had its restriction changed.
8335 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8337 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8339 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8341 Integer signedness and overflow and related fixes. (Bug#9079)
8343 * bidi.c: Integer size and overflow fixes.
8344 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8345 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8346 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8347 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8348 (bidi_find_other_level_edge):
8349 Use ptrdiff_t instead of EMACS_INT where either will do.
8350 This works better on 32-bit hosts configured --with-wide-int.
8351 (bidi_cache_ensure_space): Check for size-calculation overflow.
8352 Use % rather than repeated addition, for better worst-case speed.
8353 Don't set bidi_cache_size until after xrealloc returns, because it
8355 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8356 (bidi_cache_ensure_space): Also check that the bidi cache size
8357 does not exceed that of the largest Lisp string or buffer. See Eli
8358 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8360 * alloc.c (__malloc_size_t): Remove.
8361 All uses replaced by size_t. See Andreas Schwab's note
8362 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8364 * image.c: Improve checking for integer overflow.
8365 (check_image_size): Assume that f is nonnull, since
8366 it is always nonnull in practice. This is one less thing to
8367 worry about when checking for integer overflow later.
8368 (x_check_image_size): New function, which checks for integer
8369 overflow issues inside X.
8370 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8371 This removes the need for a memory_full check.
8372 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8373 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8374 (xbm_read_bitmap_data): Change locals back to 'int', since
8375 their values must fit in 'int'.
8376 (xpm_load_image, png_load, tiff_load):
8377 Invoke x_create_x_image_and_pixmap earlier,
8378 to avoid much needless work if the image is too large.
8379 (tiff_load): Treat overly large images as if
8380 x_create_x_image_and_pixmap failed, not as malloc failures.
8381 (gs_load): Use x_check_image_size.
8383 * gtkutil.c: Omit integer casts.
8384 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8385 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8387 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8389 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8390 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8391 would wrongly return t on a 64-bit host.
8393 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8394 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8395 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8396 and therefore cause GCC to emit a bogus diagnostic in some cases.
8398 * image.c: Integer signedness and overflow and related fixes.
8399 This is not an exhaustive set of fixes, but it's time to
8400 record what I've got.
8401 (lookup_pixel_color, check_image_size): Remove redundant decls.
8402 (check_image_size): Don't assume that arbitrary EMACS_INT values
8403 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8404 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8405 (tiff_load, imagemagick_load_image):
8406 Check for overflow in size calculations.
8407 (x_create_x_image_and_pixmap): Remove unnecessary test for
8408 xmalloc returning NULL; that can't happen.
8409 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8410 (xpm_color_bucket): Use better integer hashing function.
8411 (xpm_cache_color): Don't possibly over-allocate memory.
8412 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8413 (gif_memory_source):
8414 Use ptrdiff_t, not int or size_t, to record sizes.
8415 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8416 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8417 either works, as we prefer signed integers.
8418 (tiff_read_from_memory, tiff_write_from_memory):
8419 Return tsize_t, not size_t, since that's what the TIFF API wants.
8420 (tiff_read_from_memory): Don't fail simply because the read would
8421 go past EOF; instead, return a short read.
8422 (tiff_load): Omit no-longer-needed casts.
8423 (Fimagemagick_types): Don't assume size fits into 'int'.
8425 Improve hashing quality when configured --with-wide-int.
8426 * fns.c (hash_string): New function, taken from sxhash_string.
8427 Do not discard information about ASCII character case; this
8428 discarding is no longer needed.
8429 (sxhash-string): Use it. Change sig to match it. Caller changed.
8430 * lisp.h: Declare it.
8431 * lread.c (hash_string): Remove, since we now use fns.c's version.
8432 The fns.c version returns a wider integer if --with-wide-int is
8433 specified, so this should help the quality of the hashing a bit.
8435 * emacs.c: Integer overflow minor fix.
8436 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8437 Define only if GNU_LINUX.
8438 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8440 * dispnew.c: Integer signedness and overflow fixes.
8441 Remove unnecessary forward decls, that were a maintenance hassle.
8442 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8444 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8445 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8446 (prepare_desired_row, line_draw_cost):
8447 Use int, not unsigned, where either works.
8448 (save_current_matrix, restore_current_matrix):
8449 Use ptrdiff_t, not size_t, where either works.
8450 (init_display): Check for overflow more accurately, and without
8451 relying on undefined behavior.
8453 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8454 Remove, replacing with the new symbols in lisp.h. All uses changed.
8455 * fileio.c (make_temp_name):
8456 * filelock.c (lock_file_1, lock_file):
8457 * xdisp.c (message_dolog):
8458 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8459 Use pMd etc. instead.
8460 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8461 replacing the pWIDE etc. symbols removed from editfns.c.
8463 * keyboard.h (num_input_events): Now uintmax_t.
8464 This is (very slightly) less likely to mess up due to wraparound.
8467 * buffer.c: Integer signedness fixes.
8468 (alloc_buffer_text, enlarge_buffer_text):
8469 Use ptrdiff_t rather than size_t when either will do, as we prefer
8472 * alloc.c: Integer signedness and overflow fixes.
8473 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8474 (__malloc_size_t): Default to size_t, not to int.
8475 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8476 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8477 Prefer ptrdiff_t to size_t when either would do, as we prefer
8479 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8480 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8481 Now const. Initialize with values that are in range even if char
8483 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8484 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8485 These functions do the right thing with sizes > 2**32.
8486 (check_depth): Now ptrdiff_t, not int.
8487 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8488 Adjust to new way of storing sizes. Check for size overflow bugs
8490 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8491 slightly wrong anyway, as it missed one instance of
8492 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8493 (refill_memory_reserve): Omit needless cast to size_t.
8494 (mark_object_loop_halt): Mark as externally visible.
8496 * xselect.c: Integer signedness and overflow fixes.
8497 (Fx_register_dnd_atom, x_handle_dnd_message):
8498 Use ptrdiff_t, not size_t, since we prefer signed.
8499 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8500 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8501 x_dnd_atoms_size and x_dnd_atoms_length.
8503 * doprnt.c: Prefer signed to unsigned when either works.
8505 * doprnt.c (doprnt):
8507 * xdisp.c (vmessage):
8508 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8509 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8510 prefer signed arithmetic to avoid comparison confusion.
8511 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8512 but is a bit tricky.
8514 Assume freestanding C89 headers, string.h, stdlib.h.
8515 * data.c, doprnt.c, floatfns.c, print.c:
8516 Include float.h unconditionally.
8517 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8518 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8519 * regex.c: Likewise for stddef.h, string.h.
8520 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8521 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8522 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8523 (STDC_HEADERS): Remove obsolete defines.
8524 * sysdep.c: Include limits.h unconditionally.
8526 Assume support for memcmp, memcpy, memmove, memset.
8527 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8528 * regex.c (memcmp, memcpy):
8529 Remove; we assume C89 now.
8531 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8532 (__malloc_safe_bcopy): Remove; no longer needed.
8534 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8535 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8536 well either way, and we prefer signed to unsigned.
8538 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8540 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8541 closes the connection while we're reading (bug#9182).
8543 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8545 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8546 are specified (Bug#9168).
8548 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8550 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8551 Found by GCC static checking and --with-wide-int on a 32-bit host.
8553 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8555 * xdisp.c (compute_display_string_pos): Fix logic of caching
8556 previous display string position. Initialize cached_prev_pos to
8557 -1. Fixes slow-down at the beginning of a buffer.
8559 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8561 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8562 for attrs[LFACE_FONTSET_INDEX].
8564 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8566 * xml.c (parse_region): Remove unused local
8567 that was recently introduced.
8569 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8571 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8572 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8574 * xdisp.c (move_it_in_display_line_to): Record the best matching
8575 position for TO_CHARPOS while scanning the line, and restore it on
8576 exit if none of the characters scanned was an exact match.
8577 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8578 when exact match is impossible due to invisible text, and the
8579 lines are truncated.
8581 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8583 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8586 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8588 Fix a significant slow-down of cursor motion with C-n, C-p,
8589 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8590 auto-repeat under bidi redisplay in fontified buffers.
8591 * xdisp.c (compute_stop_pos_backwards): New function.
8592 (next_element_from_buffer): Call compute_stop_pos_backwards to
8593 find a suitable prev_stop when we find ourselves before
8595 (reseat): Don't look for prev_stop, as that could mean a very long
8597 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8598 <cached_disp_overlay_modiff>: Cache for last found display string
8600 (compute_display_string_pos): Return the cached position if asked
8601 about the same buffer in the same area of character positions, and
8602 the buffer wasn't changed since the time the display string
8603 position was cached.
8605 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8607 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8608 is an integer, which is important for empty lines. (Bug#9149)
8610 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8612 * frame.c (Fmodify_frame_parameters): In tty case, update the
8613 default face if necessary (Bug#4238).
8615 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8617 * editfns.c (Fstring_to_char): No need to explain what a character
8618 is in the docstring (Bug#6576).
8620 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8622 * xml.c (parse_region): Make sure we always return a tree.
8624 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8626 * xml.c (parse_region): If a document contains only comments,
8629 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8631 * xml.c (make_dom): Return comments, too.
8633 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8636 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8637 and the surrounding thread.
8638 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8639 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8640 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8642 * s/openbsd.h (BROKEN_SIGIO): Define.
8643 * unexelf.c (unexec) [__OpenBSD__]:
8644 Don't update the .mdebug section of the Alpha COFF symbol table.
8646 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8648 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8651 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8653 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8654 This fixes some race conditions on the permissions of any newly
8657 * alloc.c (valid_pointer_p): Use pipe, not open.
8658 This fixes some permissions issues when debugging.
8660 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8661 If fchown fails to set both uid and gid, try to set just gid,
8662 as that is sometimes allowed. Adjust the file's mode to eliminate
8663 setuid or setgid bits that are inappropriate if fchown fails.
8665 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>

8683 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8684 This works around a problem with the previous change to Fcopy_file.
8685 Recent glibc declares fchown with __attribute__((warn_unused_result)),

8687 fchown's return value.
8689 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8691 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

8716 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8717 quotes the next character, and doesn't affect other longer
8718 sequences (bug#8935).

8732 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8733 (elsz): Now a signed constant, not a size_t var. We prefer signed
8734 types to unsigned, to avoid integer comparison confusion. Without
8735 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8736 "cannot optimize loop, the loop counter may overflow", a symptom
8738 * indent.c (Fvertical_motion): Mark locals as initialized.
8739 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8741 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8743 * search.c (Fre_search_backward): Mention `case-fold-search' in
8744 all the re_search_* functions (bug#8138).

8785 the iterator is before prev_stop.
8786 (init_iterator): Initialize bidi_p from the default value of
8787 bidi-display-reordering, not from buffer-local value. Use the
8788 buffer-local value only if initializing for buffer iteration.

9304 Random fixes. E.g., (random) never returned negative values.
9305 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9306 subseconds part to the entropy, as that's a bit more random.
9307 Prefer signed to unsigned, since the signedness doesn't matter and
9308 in general we prefer signed. When given a limit, use a
9309 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9310 latter isn't right if USE_2_TAGS_FOR_INTS.
9311 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9312 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9325 This is more efficient than Ffile_directory_p and avoids a minor race.
9327 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9329 * buffer.c (Foverlay_put): Say what the return value is
9332 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9335 (barf_or_query_if_file_exists): Make the "File is a directory"
9336 error be more correct.
9338 * fns.c (Frequire): Remove the mention of the .gz files, since
9339 that's installation-specific, but keep the mention of
9340 `get-load-suffixes'.
9342 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9344 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9355 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9457 * eval.c (struct backtrace): Simplify and port the data structure.
9458 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9459 signed bit field, as this assumption is not portable and it makes
9460 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9461 "char debug_on_exit : 1" as this is not portable either; instead,
9462 use the portable "unsigned int debug_on_exit : 1". Remove unused

9627 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9629 Integer and buffer overflow fixes (Bug#8873).
9631 * print.c (printchar, strout): Check for string overflow.
9632 (PRINTPREPARE, printchar, strout):
9633 Don't set size unless allocation succeeds.
9635 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9636 for sizes. Check for string overflow more accurately.
9637 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
9639 * macros.c: Integer and buffer overflow fixes.
9640 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9641 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
9642 Use ptrdiff_t, not int, for sizes.
9643 Don't increment bufsize until after realloc succeeds.
9644 Check for size-calculation overflow.
9645 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
9647 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9649 * lread.c: Integer overflow fixes.
9650 (read_integer): Radix is now EMACS_INT, not int,
9651 to improve quality of diagnostics for out-of-range radices.
9652 Calculate buffer size correctly for out-of-range radices.
9653 (read1): Check for integer overflow in radices, and in
9654 read-circle numbers.
9655 (read_escape): Avoid int overflow.
9656 (Fload, openp, read_buffer_size, read1)
9657 (substitute_object_recurse, read_vector, read_list, map_obarray):
9658 Use ptrdiff_t, not int, for sizes.
9659 (read1): Use EMACS_INT, not int, for sizes.
9660 Check for size overflow.
9662 * image.c (cache_image): Check for size arithmetic overflow.

9665 (saved_doc_string_size, saved_doc_string_length)
9666 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9667 Now ptrdiff_t, not int.
9668 (read1): Don't assume doc string length fits in int. Check for
9669 out-of-range doc string lengths.
9670 (read_list): Don't assume file position fits in int.
9671 (read_escape): Check for hex character overflow.
9673 2011-06-22 Leo Liu <sdl.web@gmail.com>
9675 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9676 Move to minibuffer.el.
9678 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9680 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9681 The following patches are for when GLYPH_DEBUG && !XASSERT.
9682 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9683 * dispnew.c (flush_stdout):
9684 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9685 Mark as externally visible.
9686 * dispnew.c (check_window_matrix_pointers): Now static.
9687 * dispnew.c (window_to_frame_vpos):
9688 * xfns.c (unwind_create_frame):
9689 * xterm.c (x_check_font): Remove unused local.
9690 * scroll.c (CHECK_BOUNDS):
9691 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9692 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9693 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9694 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9695 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9697 (debug_method_add): Use va_list and vsprintf rather than relying
9698 on undefined behavior with wrong number of arguments.
9699 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9700 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9701 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9702 since we're not interested in debugging glyphs with old libraries.
9703 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9704 GCC 4.6.0's static checking.
9706 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9708 Integer overflow and signedness fixes (Bug#8873).
9709 A few related buffer overrun fixes, too.
9711 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
9713 * dispextern.h (struct face.stipple):
9714 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9715 (x_bitmap_mask, x_allocate_bitmap_record)
9716 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9717 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9718 (x_create_bitmap_from_xpm_data):
9719 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9720 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9722 * xfaces.c (load_pixmap):
9723 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9724 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9725 (.bitmaps_last, struct x_output.icon_bitmap):
9726 Use ptrdiff_t, not int, for bitmap indexes.
9727 (x_allocate_bitmap_record): Check for size overflow.
9728 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9730 Use ptrdiff_t, not int, for overlay counts.
9731 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9732 * editfns.c (overlays_around, get_pos_property):
9733 * textprop.c (get_char_property_and_overlay):
9734 * xdisp.c (next_overlay_change, note_mouse_highlight):
9735 * xfaces.c (face_at_buffer_position):
9736 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9737 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9738 (Fnext_overlay_change, Fprevious_overlay_change)
9739 (mouse_face_overlay_overlaps, Foverlays_in):
9740 Use ptrdiff_t, not int, for sizes.
9741 (overlays_at, overlays_in): Check for size-calculation overflow.
9743 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9745 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9746 (x_session_initialize): Do not assume string length fits in int.
9748 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9749 This is unlikely, but can occur if DPI is outlandish.
9751 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9752 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9754 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9755 * xrdb.c (magic_file_p, search_magic_path):
9756 Omit last arg SUFFIX; it was always 0. All callers changed.
9757 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9759 * xfont.c (xfont_match): Avoid need for strlen.
9761 * xfns.c: Don't assume strlen fits in int.
9762 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9764 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9765 not unsigned long, as we prefer signed integers. All callers changed.
9766 Detect integer overflow in repeat count.
9767 (message_dolog): Don't assume print length fits in 39 bytes.
9768 (display_mode_element): Don't assume strlen fits in int.
9770 * termcap.c: Don't assume sizes fit in int and never overflow.
9771 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9772 (gobble_line): Check for size-calculation overflow.
9774 * minibuf.c (Fread_buffer):
9775 * lread.c (intern, intern_c_string):
9776 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9777 Don't assume string length fits in int.
9779 * keyboard.c (parse_tool_bar_item):
9780 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9782 * font.c: Don't assume string length fits in int.
9783 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9784 Use ptrdiff_t, not int.
9785 (font_intern_prop): Don't assume string length fits in int.
9786 Don't assume integer property fits in fixnum.
9787 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9789 * filelock.c: Fix some buffer overrun and integer overflow issues.
9790 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9791 Reformulate so as not to need the command string.
9792 Invoke gzip -cd rather than gunzip, as it's more portable.
9793 (lock_info_type, lock_file_1, lock_file):
9794 Don't assume pid_t and time_t fit in unsigned long.
9795 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9796 (current_lock_owner): Prefer signed type for sizes.
9797 Use memcpy, not strncpy, where memcpy is what is really wanted.
9798 Don't assume (via atoi) that time_t and pid_t fit in int.
9799 Check for time_t and/or pid_t out of range, e.g., via a network share.
9800 Don't alloca where an auto var works fine.
9802 * fileio.c: Fix some integer overflow issues.
9803 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9804 Don't assume string length fits in int.
9805 (directory_file_name): Don't assume string length fits in long.
9806 (make_temp_name): Don't assume pid fits in int, or that its print
9807 length is less than 20.
9809 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9811 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9813 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9815 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9816 We prefer signed integers, even for size calculations.
9818 * emacs.c: Don't assume string length fits in 'int'.
9819 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9820 (main): Don't invoke strlen when not needed.
9822 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9823 (XD_DEBUG_MESSAGE): Don't waste a byte.
9825 * callproc.c (getenv_internal_1, getenv_internal)
9827 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9829 * lread.c (invalid_syntax): Omit length argument.
9830 All uses changed. This doesn't fix a bug, but it simplifies the
9831 code away from its former Hollerith-constant appearance, and it's
9832 one less 'int' to worry about when looking at integer-overflow issues.
9833 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9835 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9836 This didn't break anything, but it didn't help either.
9837 It's confusing to put a bogus integer in a place where the actual
9838 value does not matter.
9839 (LIST_END_P): Remove unused macro and its bogus comment.
9840 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9842 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9843 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9845 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9846 We prefer signed types, and the value cannot exceed the EMACS_INT
9847 range anyway (because otherwise the length would not be representable).
9848 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9849 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9850 This avoids a GCC warning when WIDE_EMACS_INT.
9852 * indent.c (sane_tab_width): New function.
9853 (current_column, scan_for_column, Findent_to, position_indentation)
9854 (compute_motion): Use it. This is just for clarity.
9855 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9857 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9859 * lisp.h (lint_assume): New macro.
9860 * composite.c (composition_gstring_put_cache):
9861 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9863 * editfns.c, insdel.c:
9864 Omit unnecessary forward decls, to simplify future changes.
9866 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9868 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9870 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9871 Use much-faster test for byte-length change.
9872 Don't assume string byte-length fits in 'int'.
9873 Check that character arg fits in 'int'.
9874 (mapcar1): Declare byte as byte, for clarity.
9876 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9878 * fns.c (concat): Catch string overflow earlier.
9879 Do not rely on integer wraparound.
9881 * dispextern.h (struct it.overlay_strings_charpos)
9882 (struct it.selective): Now EMACS_INT, not int.
9883 * xdisp.c (forward_to_next_line_start)
9884 (back_to_previous_visible_line_start)
9885 (reseat_at_next_visible_line_start, next_element_from_buffer):
9886 Don't arbitrarily truncate the value of 'selective' to int.
9888 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9890 * composite.c: Don't truncate sizes to 'int'.
9891 (composition_gstring_p, composition_reseat_it)
9892 (composition_adjust_point): Use EMACS_INT, not int.
9893 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9894 not EMACS_UINT, for indexes.
9896 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9898 * buffer.c: Include <verify.h>.
9899 (struct sortvec.priority, struct sortstr.priority):
9900 Now EMACS_INT, not int.
9901 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9902 (struct sortstr.size, record_overlay_string)
9903 (struct sortstrlist.size, struct sortlist.used):
9904 Don't truncate size to int.
9905 (record_overlay_string): Check for size-calculation overflow.
9906 (init_buffer_once): Check at compile-time, not run-time.
9908 2011-06-22 Jim Meyering <meyering@redhat.com>
9910 Don't leak an XBM-image-sized buffer
9911 * image.c (xbm_load): Free the image buffer after using it.
9913 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9916 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9917 that Sun C diagnosed.
9918 * fns.c (secure_hash): Fix pointer signedness issue.
9919 * intervals.c (static_offset_intervals): New function.
9920 (offset_intervals): Use it.
9922 2011-06-21 Leo Liu <sdl.web@gmail.com>
9925 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9928 * fns.c (secure_hash): Rename from crypto_hash_function and change
9929 the first arg to accept symbols.
9930 (Fsecure_hash): New primitive.
9931 (syms_of_fns): New symbols.
9933 2011-06-20 Deniz Dogan <deniz@dogan.se>
9935 * process.c (Fset_process_buffer): Clarify return value in
9938 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9940 * dispnew.c (add_window_display_history): Use BVAR.
9942 * xdisp.c (debug_method_add): Use BVAR.
9943 (check_window_end, dump_glyph_matrix, dump_glyph)
9944 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9946 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9949 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9950 check till after the cache is created in init_frame_faces.
9952 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9954 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9956 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9958 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9959 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9960 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9962 Improve buffer-overflow checking (Bug#8873).
9963 * fileio.c (Finsert_file_contents):
9964 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9965 Remove the old (too-loose) buffer overflow checks.
9966 They weren't needed, since make_gap checks for buffer overflow.
9967 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9968 The old code merely checked for Emacs fixnum overflow, and relied
9969 on undefined (wraparound) behavior. The new code avoids undefined
9970 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9972 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9973 Tune. Don't use wider integers than needed. Don't use alloca.
9974 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9976 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9978 * insdel.c, lisp.h (buffer_overflow): New function.
9979 (insert_from_buffer_1, replace_range, replace_range_2):
9980 * insdel.c (make_gap_larger):
9981 * editfns.c (Finsert_char):
9982 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9984 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9986 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9988 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9990 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9991 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9993 * fileio.c: Don't assume EMACS_INT fits in off_t.
9994 (emacs_lseek): New static function.
9995 (Finsert_file_contents, Fwrite_region): Use it.
9996 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9998 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10000 * fns.c: Don't overflow int when computing a list length.
10001 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10002 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10003 truncation on 64-bit hosts. Check for QUIT every
10004 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10005 faster and is responsive enough.
10006 (Flength): Report an error instead of overflowing an integer.
10007 (Fsafe_length): Return a float if the value is not representable
10008 as a fixnum. This shouldn't happen except in contrived situations.
10009 (Fnthcdr, Fsort): Don't assume list length fits in int.
10010 (Fcopy_sequence): Don't assume vector length fits in int.
10012 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10013 (header_size, word_size): New constants.
10014 (allocate_vectorlike): Don't check size overflow here.
10015 (allocate_vector): Check it here instead, since this is the only
10016 caller of allocate_vectorlike that could cause overflow.
10017 Check that the new vector's length is representable as a fixnum.
10019 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10020 The previous code was bogus. For example, next_almost_prime (32)
10021 returned 39, which is undesirable as it is a multiple of 3; and
10022 next_almost_prime (24) returned 25, which is a multiple of 5 so
10023 why was the code bothering to check for multiples of 7?
10025 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10027 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10029 Variadic C functions now count arguments with ptrdiff_t.
10030 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10031 Back then I didn't know that the Emacs coding style prefers signed int.
10032 Also, in the meantime I found a few more instances where arguments
10033 were being counted with int, which may truncate counts on 64-bit
10034 machines, or EMACS_INT, which may be unnecessarily wide.
10035 * lisp.h (struct Lisp_Subr.function.aMANY)
10036 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10037 Arg counts are now ptrdiff_t, not size_t.
10038 All variadic functions and their callers changed accordingly.
10039 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10040 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10041 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10042 * callint.c (Fcall_interactively): Check arg count for overflow,
10043 to avoid potential buffer overrun. Use signed char, not 'int',
10044 for 'varies' array, so that we needn't bother to check its size
10045 calculation for overflow.
10046 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10047 * eval.c (apply_lambda):
10048 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10049 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10050 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10052 * callint.c (Fcall_interactively): Don't use index var as event count.
10054 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10055 * mem-limits.h (SIZE): Remove; no longer used.
10057 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10059 Remove unnecessary casts.
10060 * xterm.c (x_term_init):
10061 * xfns.c (x_set_border_pixel):
10062 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10063 These aren't needed now that we assume ANSI C.
10065 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10066 It's more likely to cause problems (due to unsigned overflow)
10069 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10071 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10073 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10075 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10077 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10079 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10081 GLYPH_CODE_FACE returns EMACS_INT, not int.
10082 * dispextern.h (merge_faces):
10083 * xfaces.c (merge_faces):
10084 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10085 Don't assume EMACS_INT fits in int.
10087 * character.h (CHAR_VALID_P): Remove unused parameter.
10088 * fontset.c, lisp.h, xdisp.c: All uses changed.
10090 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10092 * fns.c (concat): Minor tuning based on overflow analysis.
10093 This doesn't fix any bugs. Use int to hold character, instead
10094 of constantly refetching from Emacs object. Use XFASTINT, not
10095 XINT, for value known to be a character. Don't bother comparing
10096 a single byte to 0400, as it's always less.
10098 * floatfns.c (Fexpt):
10099 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10101 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10104 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10106 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10107 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10108 incorrectly succeed when S was a string, because 4294967386 was
10109 truncated before it was used.
10111 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10112 Otherwise, an out-of-range integer could cause undefined behavior
10115 * composite.c: Use int, not EMACS_INT, for characters.
10116 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10117 EMACS_INT, for values that are known to be in character range.
10118 This doesn't fix any bugs but is the usual style inside Emacs and
10119 may generate better code on 32-bit machines.
10121 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10122 This is for reasons similar to the recent CHAR_STRING fix.
10123 * charset.c (Fencode_char): Check that character arg is actually
10124 a character. Pass an int to ENCODE_CHAR.
10125 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10126 wider than 'int', as a compile-time check to prevent future regressions
10129 * character.c (char_string): Remove unnecessary casts.
10131 Make sure a 64-bit char is never passed to CHAR_STRING.
10132 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10133 by silently ignoring the top 32 bits, allowing some values
10134 that were far too large to be valid characters.
10135 * character.h: Include <verify.h>.
10136 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10137 arguments are no wider than unsigned, as a compile-time check
10138 to prevent future regressions in this area.
10140 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10141 (Fsubst_char_in_region):
10143 * xdisp.c (decode_mode_spec_coding):
10144 Adjust to CHAR_STRING's new requirement.
10145 * editfns.c (Finsert_char, Fsubst_char_in_region):
10146 * fns.c (concat): Check that character args are actually
10147 characters. Without this test, these functions did the wrong
10148 thing with wildly out-of-range values on 64-bit hosts.
10150 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10151 These casts should not be needed on 32-bit hosts, either.
10152 * keyboard.c (read_char):
10153 * lread.c (Fload): Remove casts to unsigned.
10155 * lisp.h (UNSIGNED_CMP): New macro.
10156 This fixes comparison bugs on 64-bit hosts.
10157 (ASCII_CHAR_P): Use it.
10158 * casefiddle.c (casify_object):
10159 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10160 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10161 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10162 * dispextern.h (FACE_FROM_ID):
10163 * keyboard.c (read_char): Use UNSIGNED_CMP.
10165 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10166 not to EMACS_INT, to avoid GCC warning.
10168 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10170 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10171 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10172 isn't needed on 32-bit machines.
10174 * buffer.c (Fgenerate_new_buffer_name):
10175 Use EMACS_INT for count, not int.
10176 (advance_to_char_boundary): Return EMACS_INT, not int.
10178 * data.c (Qcompiled_function): Now static.
10180 * window.c (window_body_lines): Now static.
10182 * image.c (gif_load): Rename local to avoid shadowing.
10184 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10185 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10186 * alloc.c (make_save_value): Integer argument is now of type
10187 ptrdiff_t, not int.
10188 (mark_object): Use ptrdiff_t, not int.
10189 * lisp.h (pD): New macro.
10190 * print.c (print_object): Use it.
10192 * alloc.c: Use EMACS_INT, not int, to count objects.
10193 (total_conses, total_markers, total_symbols, total_vector_size)
10194 (total_free_conses, total_free_markers, total_free_symbols)
10195 (total_free_floats, total_floats, total_free_intervals)
10196 (total_intervals, total_strings, total_free_strings):
10197 Now EMACS_INT, not int. All uses changed.
10198 (Fgarbage_collect): Compute overall total using a double, so that
10199 integer overflow is less likely to be a problem. Check for overflow
10200 when converting back to an integer.
10201 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10202 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10203 These were 'int' variables that could overflow on 64-bit hosts;
10204 they were never used, so remove them instead of repairing them.
10205 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10206 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10207 Previously, this ceilinged at INT_MAX, but that doesn't work on
10209 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10211 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10212 (allocate_vectorlike): Check for ptrdiff_t overflow.
10213 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10214 when a (possibly-narrower) signed value would do just as well.
10215 We prefer using signed arithmetic, to avoid comparison confusion.
10217 * alloc.c: Catch some string size overflows that we were missing.
10218 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10219 for convenience in STRING_BYTES_MAX.
10220 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10221 The definition here is exact; the one in lisp.h was approximate.
10222 (allocate_string_data): Check for string overflow. This catches
10223 some instances we weren't catching before. Also, it catches
10224 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10225 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10226 and ptrdiff_t and EMACS_INT are both 64 bits.
10228 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10229 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10230 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10232 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10234 * alloc.c (Fmake_string): Check for out-of-range init.
10236 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10238 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10240 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10242 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10243 xg_get_default_scrollbar_width.
10245 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10246 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10247 (style_changed_cb): Call update_theme_scrollbar_width and call
10248 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10249 all frames (Bug#8505).
10250 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10251 Call gtk_window_set_resizable if HAVE_GTK3.

10253 and height if HAVE_GTK3 (Bug#8505).
10254 (scroll_bar_width_for_theme): New variable.
10255 (update_theme_scrollbar_width): New function.
10256 (xg_get_default_scrollbar_width): Move code to
10257 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10258 (xg_initialize): Call update_theme_scrollbar_width.
10260 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10262 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10264 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10266 * frame.c (make_frame): Call other_buffer_safely instead of
10269 * window.c (temp_output_buffer_show): Call display_buffer with
10270 second argument Vtemp_buffer_show_specifiers and reset latter
10271 immediately after the call.
10272 (Vtemp_buffer_show_specifiers): New variable.
10273 (auto_window_vscroll_p, next_screen_context_lines)
10274 (Vscroll_preserve_screen_position): Remove leading asterisks from
10277 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10279 Fix minor problems found by GCC 4.6.0 static checking.

10281 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10282 (record_buffer): Remove unused local.
10283 * frame.c (other_visible_frames, frame_buffer_list): Now static.

10295 * widgetprv.h (emacsFrameClassRec): Remove decl.
10296 * window.c (delete_deletable_window): Now returns void, since it
10297 wasn't returning anything.
10298 (compare_window_configurations): Remove unused locals.
10299 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

10315 (syms_of_image): Use DEFSYM. New symbol `delay'.
10317 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10319 * window.c (delete_deletable_window): Re-add.
10320 (Fset_window_configuration): Rewrite to handle dead buffers and
10321 consequently deletable windows.
10322 (window_tree, Fwindow_tree): Remove. Supply functionality in
10324 (compare_window_configurations): Simplify code.

10335 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10336 Qclone_number. Remove external declaration of Qdelete_window.
10337 (Fbuffer_list): Rewrite doc-string. Minor restructuring of

10342 buffer list implementation.
10343 (other_buffer_safely): New function.

10452 2011-06-10 Martin Rudalics <rudalics@gmx.at>
10454 * window.c: Remove declarations of Qwindow_size_fixed,
10455 window_min_size_1, window_min_size_2, window_min_size,
10456 size_window, window_fixed_size_p, enlarge_window, delete_window.
10457 Remove static from declaration of Qdelete_window, it's
10458 temporarily needed by Fbury_buffer.
10459 (replace_window): Don't assign orig_top_line and
10461 (Fdelete_window, delete_window): Remove. Window deletion is

10463 (window_loop): Remove DELETE_OTHER_WINDOWS case.
10464 Replace Fdelete_window calls with calls to Qdelete_window.
10465 (Fdelete_other_windows): Remove. Deleting other windows is

10838 value of a `display' property is a "replacing spec".
10839 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10840 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10870 * gnutls.c: Use Emacs's memory allocators.
10871 Without this change, the gnutls library would invoke malloc etc.
10872 directly, which causes problems on non-SYNC_INPUT hosts, and which
10873 runs afoul of improving memory_full behavior. (Bug#8761)
10874 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10875 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10876 xfree instead of the default malloc, realloc, free.
10877 (Fgnutls_boot): No need to check for memory allocation failure,
10878 since xmalloc does that for us.

10906 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10907 need to be updated by these changes.
10908 * fns.c (make_hash_table, maybe_resize_hash_table):
10909 Check for integer overflow with large hash tables.
10910 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10911 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10912 (SXHASH_REDUCE): New macro.
10913 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10914 Use it instead of discarding useful hash info with large hash values.
10915 (sxhash_float): New function.
10916 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10917 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10918 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10919 Rewrite to use FIXNUM_BITS, as this simplifies things.
10920 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10921 Adjust signatures to match updated version of code.
10922 (consing_since_gc): Now EMACS_INT, since a single hash table can
10923 use more than INT_MAX bytes.
10925 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
10927 Make it possible to build with GCC-4.6+ -O2 -flto.
10929 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
10931 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
10933 * minibuf.c (get_minibuffer, read_minibuf_unwind):
10934 Call minibuffer-inactive-mode.
10936 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
10938 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
10939 Update dependencies.
10941 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10943 * data.c (init_data): Remove code for UTS, this system is not
10946 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10948 Don't force ./temacs to start in terminal mode.
10950 * frame.c (make_initial_frame): Initialize faces in all cases, not
10951 only when CANNOT_DUMP is defined.
10952 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10954 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10956 * dispnew.c (add_window_display_history): Use const for the string
10957 pointer. Remove declaration, not needed.
10959 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10961 Use 'inline', not 'INLINE'.
10962 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10963 * alloc.c, fontset.c (INLINE): Remove.
10964 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10965 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10966 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10967 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10968 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10970 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10972 Make it possible to run ./temacs.
10974 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10975 syms_of_callproc does the same thing. Remove test for
10976 "initialized", do it in the caller.
10977 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10979 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10981 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10982 (read_minibuf): Use get_minibuffer.
10983 (syms_of_minibuf): Use DEFSYM.
10984 (Qmetadata): New var.
10985 * data.c (Qbuffer): Don't make it static.
10986 (syms_of_data): Use DEFSYM.
10988 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10990 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10991 (CCL_CODE_MIN): New macro.
10993 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10995 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10997 * eval.c (Qdebug): Now static.
10998 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10999 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11000 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11002 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11004 * image.c: Various fixes to ImageMagick code comments.
11005 (Fimagemagick_types): Doc fix.
11007 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11009 Minor fixes prompted by GCC 4.6.0 warnings.
11011 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11013 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11014 (x_clipboard_manager_save_all): Move extern decl to ...
11015 * xterm.h: ... here, so that it can be checked for consistency.
11017 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11019 * xselect.c (x_clipboard_manager_save_frame)
11020 (x_clipboard_manager_save_all): New functions.
11021 (Fx_clipboard_manager_save): Lisp function deleted.
11023 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11024 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11026 * xterm.h: Update prototype.
11028 2011-05-28 William Xu <william.xwl@gmail.com>
11030 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11031 exiting (Bug#8239).
11033 2011-05-28 Jim Meyering <meyering@redhat.com>
11035 Avoid a sign-extension bug in crypto_hash_function.
11036 * fns.c (to_uchar): Define.
11037 (crypto_hash_function): Use it to convert some newly-signed
11038 variables to unsigned, to avoid sign-extension bugs. For example,
11039 without this change, (md5 "truc") would evaluate to
11040 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11041 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11042 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11046 Integer overflow fixes.
11048 * dbusbind.c: Serial number integer overflow fixes.
11049 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11050 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11051 to hold a serial number that is too large for a fixnum.
11052 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11053 Check for serial numbers out of range. Decode any serial number
11054 that was so large that it became a float. (Bug#8722)
11056 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11057 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11058 Use XFASTINT rather than XUINT when numbers are nonnegative.
11059 (xd_append_arg, Fdbus_method_return_internal):
11060 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11061 arguments, check that Lisp number is nonnegative, rather than
11062 silently wrapping negative numbers around. (Bug#8722)
11063 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11066 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11068 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11070 ccl: Add integer overflow checks.
11071 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11072 (IN_INT_RANGE): New macros.
11073 (ccl_driver): Use them to check for integer overflow when
11074 decoding a CCL program. Many of the new checks are whether XINT (x)
11075 fits in int; it doesn't always, on 64-bit hosts. The new version
11076 doesn't catch all possible integer overflows, but it's an
11077 improvement. (Bug#8719)
11079 * alloc.c (make_event_array): Use XINT, not XUINT.
11080 There's no need for unsigned here.
11082 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11083 This follows up to the 2011-05-06 change that substituted uintptr_t
11084 for EMACS_INT. This case wasn't caught back then.
11086 Rework Fformat to avoid integer overflow issues.
11087 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11088 now (part of C89). Include <verify.h>.
11089 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11090 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11091 (Fformat): Avoid the prepass trying to compute sizes; it was only
11092 approximate and thus did not catch overflow reliably. Instead, walk
11093 through the format just once, formatting and computing sizes as we go,
11094 checking for integer overflow at every step, and allocating a larger
11095 buffer as needed. Keep track separately whether the format is
11096 multibyte. Keep only the most-recently calculated precision, rather
11097 than them all. Record whether each argument has been converted to
11098 string. Use EMACS_INT, not int, for byte and char and arg counts.
11099 Support field widths and precisions larger than INT_MAX. Avoid
11100 sprintf's undefined behavior with conversion specifications such as %#d
11101 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11102 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11103 formatting out-of-range floating point numbers with int
11104 formats. (Bug#8668)
11106 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11108 * data.c: Avoid integer truncation in expressions involving floats.
11109 * data.c: Include <intprops.h>.
11110 (arith_driver): When there's an integer overflow in an expression
11111 involving floating point, convert the integers to floating point
11112 so that the resulting value does not suffer from catastrophic
11113 integer truncation. For example, on a 64-bit host (* 4
11114 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11115 Do not rely on undefined behavior after integer overflow.
11117 merge count_size_as_multibyte, parse_str_to_multibyte
11118 * character.c, character.h (count_size_as_multibyte):
11119 Rename from parse_str_to_multibyte; all uses changed.
11120 Check for integer overflow.
11121 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11122 since it's now a duplicate of the other. This is more of
11123 a character than a buffer op, so better that it's in character.c.
11124 * fns.c, print.c: Adjust to above changes.
11126 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11128 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11130 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11132 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11133 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11134 (x_clipboard_manager_save): Now static.
11135 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11137 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11138 (crypto_hash_function): Now static.
11139 Fix pointer signedness problems. Avoid unnecessary initializations.
11141 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11143 * termhooks.h (Vselection_alist): Make it terminal-local.
11145 * terminal.c (create_terminal): Initialize it.
11147 * xselect.c: Support for clipboard managers.
11148 (Vselection_alist): Move to termhooks.h as terminal-local var.
11149 (LOCAL_SELECTION): New macro.
11150 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11151 (symbol_to_x_atom): Remove gratuitous arg.
11152 (x_handle_selection_request, lisp_data_to_selection_data)
11153 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11154 (x_own_selection, x_get_local_selection, x_convert_selection):
11155 New arg, specifying work frame. Use terminal-local Vselection_alist.
11156 (some_frame_on_display): Delete unused function.
11157 (Fx_own_selection_internal, Fx_get_selection_internal)
11158 (Fx_disown_selection_internal, Fx_selection_owner_p)
11159 (Fx_selection_exists_p): New optional frame arg.
11160 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11161 (x_handle_selection_clear): Don't treat other terminals with the
11162 same keyboard specially. Use the terminal-local Vselection_alist.
11163 (x_clear_frame_selections): Use Frun_hook_with_args.
11165 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11167 * xterm.h: Add support for those atoms.
11169 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11171 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11172 (converted_selections, conversion_fail_tag): New global variables.
11173 (x_selection_request_lisp_error): Free the above.
11174 (x_get_local_selection): Remove unnecessary code.
11175 (x_reply_selection_request): Args changed; handle arbitrary array
11176 of converted selections stored in converted_selections.
11177 Separate the XChangeProperty and SelectionNotify steps.
11178 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11179 (x_convert_selection): New function.
11180 (x_handle_selection_event): Simplify.
11181 (x_get_foreign_selection): Don't ignore incoming requests while
11182 waiting for an answer; this will fail when we implement
11183 SAVE_TARGETS, and seems unnecessary anyway.
11184 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11185 (Vx_sent_selection_functions): Doc fix.
11187 2011-05-26 Leo Liu <sdl.web@gmail.com>
11189 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11191 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11193 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11195 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11196 for fringe update if it has periodic bitmap.
11197 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11198 and fringe_bitmap_periodic_p.
11200 * fringe.c (get_fringe_bitmap_data): New function.
11201 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11202 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11203 row. Mark glyph row for fringe update if periodicity changed.
11205 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11206 for fringe update unless it has periodic bitmap.
11208 2011-05-25 Kenichi Handa <handa@m17n.org>
11210 * xdisp.c (get_next_display_element): Set correct it->face_id for
11211 a static composition.
11213 2011-05-24 Leo Liu <sdl.web@gmail.com>
11216 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11218 * fns.c (crypto_hash_function, Fsha1): New function.
11219 (Fmd5): Use crypto_hash_function.
11220 (syms_of_fns): Add Ssha1.
11222 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11224 * gnutls.c: Remove unused macros.
11225 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11226 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11227 Remove macros that are defined and never used.
11228 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11230 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11232 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11233 (Fx_get_selection_internal): Minor cleanup.
11234 (Fx_own_selection_internal): Rename arguments for consistency with
11237 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11239 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11241 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11243 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11245 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11247 * dispnew.c (scrolling_window): Don't exclude the case that the
11248 last enabled row in the desired matrix touches the bottom boundary.
11250 2011-05-21 Glenn Morris <rgm@gnu.org>
11252 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11253 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11254 and add some more files.
11256 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11258 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11259 report_file_error introduced by the change from 2011-05-07.
11261 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11263 * systime.h (Time): Define only if emacs is defined.
11264 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11265 where the include path doesn't have X11/X.h by default. See
11266 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11268 2011-05-20 Kenichi Handa <handa@m17n.org>
11270 * composite.c (find_automatic_composition): Fix previous change.
11272 2011-05-20 Glenn Morris <rgm@gnu.org>
11274 * lisp.mk: New file, split from Makefile.in.
11275 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11276 (shortlisp): Remove.
11277 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11279 2011-05-19 Glenn Morris <rgm@gnu.org>
11281 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11282 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11283 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11284 (lisp): Set the order to that of loadup.el.
11285 (shortlisp): Make it a copy of $lisp.
11286 (SOME_MACHINE_LISP): Remove.
11287 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11288 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11290 2011-05-18 Kenichi Handa <handa@m17n.org>
11292 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11293 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11294 (find_automatic_composition): Mostly rewrite for efficiency.
11296 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11298 * makefile.w32-in: Update dependencies.
11300 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11302 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11303 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11305 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11307 Fix some integer overflow issues, such as string length overflow.
11309 * insdel.c (count_size_as_multibyte): Check for string overflow.
11311 * character.c (lisp_string_width): Check for string overflow.
11312 Use EMACS_INT, not int, for string indexes and lengths; in
11313 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11314 the resulting string length overflows an EMACS_INT; instead,
11315 report a string overflow if no precision given. When checking for
11316 precision exhaustion, use a check that cannot possibly have
11317 integer overflow. (Bug#8675)
11318 * character.h (lisp_string_width): Adjust to new signature.
11320 * alloc.c (string_overflow): New function.
11321 (Fmake_string): Use it. This doesn't change behavior, but saves
11322 a few bytes and will simplify future changes.
11323 * character.c (string_escape_byte8): Likewise.
11324 * lisp.h (string_overflow): New decl.
11326 Fixups, following up to the user-interface timestamp change.
11327 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11328 for UI timestamps, instead of unsigned long.
11329 * msdos.c (mouse_get_pos): Likewise.
11330 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11331 * w32gui.h (Time): Define by including "systime.h" rather than by
11332 declaring it ourselves. (Bug#8664)
11334 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11335 * image.c (clear_image_cache): Likewise.
11337 * term.c (term_mouse_position): Don't assume time_t wraparound.
11339 Be more systematic about user-interface timestamps.
11340 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11341 and sometimes 'EMACS_UINT', to represent these timestamps.
11342 This change causes it to use 'Time' uniformly, as that's what X uses.
11343 This makes the code easier to follow, and makes it easier to catch
11344 integer overflow bugs such as Bug#8664.
11345 * frame.c (Fmouse_position, Fmouse_pixel_position):
11346 Use Time, not unsigned long, for user-interface timestamps.
11347 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11348 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11349 * keyboard.h (last_event_timestamp): Likewise.
11350 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11351 * menu.h (xmenu_show): Likewise.
11352 * term.c (term_mouse_position): Likewise.
11353 * termhooks.h (struct input_event.timestamp): Likewise.
11354 (struct terminal.mouse_position_hook): Likewise.
11355 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11356 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11357 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11358 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11359 what it was before.
11360 * menu.h, termhooks.h: Include "systime.h", for Time.
11362 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11363 Don't assume that the difference between two unsigned long values
11364 can fit into an integer. At this point, we know button_down_time
11365 <= event->timestamp, so the difference must be nonnegative, so
11366 there's no need to cast the result if double-click-time is
11367 nonnegative, as it should be; check that it's nonnegative, just in
11368 case. This bug is triggered when events are more than 2**31 ms
11369 apart (about 25 days). (Bug#8664)
11371 * xselect.c (last_event_timestamp): Remove duplicate decl.
11372 (x_own_selection): Remove needless cast to unsigned long.
11374 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11375 that always fit in int. Use a sentinel instead of a counter, to
11376 avoid a temp and to allay GCC's concerns about possible int overflow.
11377 * frame.h (struct frame): Use int for menu_bar_items_used
11378 instead of EMACS_INT, since it always fits in int.
11380 * menu.c (grow_menu_items): Check for int overflow.
11382 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11384 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11385 Before, the code was not consistent. These values cannot exceed
11386 2**31 - 1 so there's no need to make them unsigned.
11387 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11388 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11389 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11391 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11393 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11394 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11395 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11396 presumably because the widths might not match.
11398 * window.c (size_window): Avoid needless test at loop start.
11400 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11402 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11404 2011-05-12 Drew Adams <drew.adams@oracle.com>
11406 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11408 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11410 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11411 `width' to `bar_area_x' and `bar_area_width', respectively.
11412 (x_scroll_run): Take account of fringe background extension.
11414 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11415 Rename local vars `left' and `width' to `bar_area_x' and
11416 `bar_area_width', respectively.
11417 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11418 background extension.
11420 2011-05-10 Jim Meyering <meyering@redhat.com>
11422 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11424 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11426 * image.c (Finit_image_library): Return t for built-in image types,
11427 like pbm and xbm. (Bug#8640)
11429 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11431 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11433 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11435 * w32console.c (Fset_screen_color): Doc fix.
11436 (Fget_screen_color): New function.
11437 (syms_of_ntterm): Defsubr it.
11439 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11440 unlink the temporary file if Fcall_process didn't create it in the
11442 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11443 child process will be redirected to a file specified with `:file'.
11444 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11445 cue to call_process_cleanup not to close that handle.
11447 2011-05-07 Ben Key <bkey76@gmail.com>
11449 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11450 one of two shell specific rules, either bootstrap-temacs-CMD or
11451 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11452 to the previous implementation of the bootstrap-temacs rule.
11453 The bootstrap-temacs-CMD rule is similar to the previous
11454 implementation of the bootstrap-temacs rule except that it
11455 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11458 These changes, along with some changes to nt/configure.bat,
11459 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11460 earlier fix to add support for --cflags and --ldflags options
11461 that include quotes so that it works whether make uses cmd or
11464 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11466 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11467 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11469 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11470 a string. Handle both cases.
11471 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11472 (Fdbus_register_method): Use Qinvalid_function.
11474 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11476 * makefile.w32-in: Update dependencies.
11477 (LISP_H): Add inttypes.h and stdin.h.
11478 (PROCESS_H): Add unistd.h.
11480 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11482 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11483 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11485 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11487 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11489 * term.c (vfatal): Remove stray call to va_end.
11490 It's not needed and the C Standard doesn't allow it here anyway.
11492 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11493 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11495 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11498 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11500 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11502 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11504 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11506 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11508 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11509 * charset.c (Fdefine_charset_internal): Don't initialize
11510 charset.code_space[15]. The value was garbage, on hosts with
11511 32-bit int (Bug#8600).
11513 * lread.c (read_integer): Be more consistent with string-to-number.
11514 Use string_to_number to do the actual conversion; this avoids
11515 rounding errors and fixes some other screwups. Without this fix,
11516 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11517 (digit_to_number): Move earlier, for benefit of read_integer.
11518 Return -1 if the digit is out of range for the base, -2 if it is
11519 not a digit in any supported base. (Bug#8602)
11521 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11523 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11524 to match comment at start of function. This also removes a
11525 GCC warning about overflow in a 32+64-bit port.
11527 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11529 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11530 Reported by Stefan Monnier in
11531 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11532 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11533 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11535 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11536 (EMACS_UINTPTR): Likewise, with uintptr_t.
11538 * lisp.h: Prefer 64-bit EMACS_INT if available.
11539 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11540 on 32-bit hosts that have 64-bit int, so that they can access
11542 However, temporarily disable this change unless the temporary
11543 symbol WIDE_EMACS_INT is defined.
11545 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11547 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11548 This removes an assumption that EMACS_INT and long are the same
11549 width as pointers. The assumption is true for Emacs porting targets
11550 now, but we want to make other targets possible.
11551 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11552 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11553 In the rest of the code, change types of integers that hold casted
11554 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11555 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11556 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11557 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11558 No need to cast type when ORing.
11559 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11560 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11561 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11562 assume EMACS_INT is the same width as char *.
11563 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11564 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11565 Remove no-longer-needed casts.
11566 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11567 (xg_tool_bar_help_callback, xg_make_tool_item):
11568 Use EMACS_INTPTR to hold an integer
11569 that will be cast to void *; this can avoid a GCC warning
11570 if EMACS_INT is not the same width as void *.
11571 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11572 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11573 (current_message_1, set_message_1):
11574 Use a local to convert to proper width without a cast.
11575 * xmenu.c (dialog_selection_callback): Likewise.
11577 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11578 Also, don't assume VALBITS / RAND_BITS is less than 5,
11579 and don't rely on undefined behavior when shifting a 1 left into
11581 * lisp.h (get_random): Change signature to match.
11583 * lread.c (hash_string): Use size_t, not int, for hash computation.
11584 Normally we prefer signed values; but hashing is special, because
11585 it's better to use unsigned division on hash table sizes so that
11586 the remainder is nonnegative. Also, size_t is the natural width
11587 for hashing into memory. The previous code used 'int', which doesn't
11588 retain enough info to hash well into very large tables.
11589 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11591 * dbusbind.c: Don't possibly lose pointer info when converting.
11592 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11593 Use XPNTR rather than XHASH, so that the high-order bits of
11594 the pointer aren't lost when converting through void *.
11596 * eval.c (Fautoload): Don't double-shift a pointer.
11598 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11600 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11602 * gnutls.c (DEF_GNUTLS_FN):
11603 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11605 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11607 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11610 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11612 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11613 New version that can reserve upto 2GB of heap space.
11615 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11617 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11619 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11621 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11622 `gnutls_certificate_set_x509_key_file'.
11624 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11626 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11627 Update dependencies.
11629 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11631 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11632 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11633 Remove unused parameter `fildes'.
11634 * process.c (read_process_output, send_process): Don't pass it.
11636 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11638 Fix previous change: the library cache is defined in w32.c.
11639 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11640 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11642 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11644 Implement dynamic loading of GnuTLS on Windows.
11646 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11647 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11648 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11651 * gnutls.c (Qgnutls_dll): Define.
11652 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11653 (gnutls_*): Declare function pointers.
11654 (init_gnutls_functions): New function to initialize function pointers.
11655 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11656 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11657 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11658 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11659 (emacs_gnutls_write, emacs_gnutls_read)
11660 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11661 (Fgnutls_available_p): New function.
11662 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11663 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11664 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11666 * image.c: Include w32.h.
11667 (Vimage_type_cache): Delete.
11668 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11669 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11670 (w32_delayed_load): Move to w32.c.
11672 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11674 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11675 (w32_delayed_load): Move from image.c. When loading a library, record
11676 its filename in the :loaded-from property of the library id.
11677 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11678 Initialize and staticpro them.
11679 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11681 * process.c: Include lisp.h before w32.h, not after.
11682 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11683 instead of gnutls_record_check_pending.
11685 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11687 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11689 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11690 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11693 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11695 * xterm.c (x_set_frame_alpha): Do not set property on anything
11696 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11698 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11700 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11702 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11704 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11705 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11711 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
11712 (Qgnutls_bootprop_callbacks_verify): Make static.
11714 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11716 * callproc.c: Indentation fixup.
11718 * sysdep.c (wait_for_termination_1): Make static.
11719 (wait_for_termination, interruptible_wait_for_termination):
11720 Move after wait_for_termination_1.
11722 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11724 * sysdep.c (interruptible_wait_for_termination): New function
11725 which is like wait_for_termination, but allows keyboard
11728 * callproc.c (Fcall_process): Add (:file "file") as an option for
11730 (Fcall_process_region): Ditto.
11732 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11734 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11735 rather than `XVECTOR (FOO)->size'.
11737 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11738 inttypes.h, as a gnulib replacement is used if it not available in
11741 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11743 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11744 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11745 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11747 * coding.c (coding_alloc_by_realloc): Error out if destination
11748 will grow beyond MOST_POSITIVE_FIXNUM.
11749 (decode_coding_emacs_mule): Abort if there isn't enough place in
11750 charbuf for the composition carryover bytes. Reserve an extra
11751 space for up to 2 characters produced in a loop.
11752 (decode_coding_iso_2022): Abort if there isn't enough place in
11753 charbuf for the composition carryover bytes.

11758 aborting when %lld or %lll format is passed.
11759 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11760 %llo or %llx format is passed. (Bug#8545)
11762 * window.c (window_scroll_line_based): Use a marker instead of
11763 simple variables to record original value of point. (Bug#7952)
11765 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11766 produced by %s or %c overflows available buffer space. (Bug#8545)

11770 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11771 (SIZE_MAX): Move defn after all includes, as they might #define it.
11773 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11775 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11777 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11779 * keyboard.c (Qdelayed_warnings_hook): Define.
11780 (command_loop_1): Run `delayed-warnings-hook'
11781 if Vdelayed_warnings_list is non-nil.
11782 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11783 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11785 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11787 * doprnt.c (doprnt): Don't return value smaller than the buffer
11788 size if the message was truncated. (Bug#8545).
11790 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11792 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11793 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11795 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11797 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11799 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11801 * makefile.w32-in: Update dependencies.
11803 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11805 Improve `doprnt' and its usage. (Bug#8545)
11806 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11807 `format_end'. Remove support for %l as a conversion specifier.
11808 Don't use xrealloc. Improve diagnostics when the %l size modifier
11809 is used. Update the commentary.
11811 * eval.c (verror): Simplify calculation of size_t.
11813 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11816 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11818 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11821 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11823 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11824 This makes this file independent of the recent pseudovector change.
11826 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11828 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11830 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11831 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11832 Remove unused local.
11833 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11835 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11836 GCC 4.6.0 optimizes based on type-based alias analysis.
11837 For example, if b is of type struct buffer * and v of type struct
11838 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11839 != &v->size, and therefore "v->size = 1; b->size = 2; return
11840 v->size;" must therefore return 1. This assumption is incorrect
11841 for Emacs, since it type-puns struct Lisp_Vector * with many other
11842 types. To fix this problem, this patch adds a new type struct
11843 vectorlike_header that documents the constraints on layout of vectors
11844 and pseudovectors, and helps optimizing compilers not get fooled
11845 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11846 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11847 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11849 (XSETPVECTYPE): Rewrite in terms of new macro.
11850 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11851 This is a bit clearer, and further avoids the possibility of
11852 undesirable aliasing.
11853 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11854 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11855 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11856 since Lisp_Subr is a special case (no "next" field).
11857 (ASIZE): Now uses header.size rather than size.
11858 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11859 to avoid the hassle of writing XVECTOR (foo)->header.size.
11860 (struct vectorlike_header): New type.
11861 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11862 object, to help avoid aliasing.
11863 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11864 (SUBRP): Likewise, since Lisp_Subr is a special case.
11865 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11866 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11867 (struct Lisp_Hash_Table): Combine first two members into a single
11868 struct vectorlike_header member. All uses of "size" and "next" members
11869 changed to be "header.size" and "header.next".
11870 * buffer.h (struct buffer): Likewise.
11871 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11872 * frame.h (struct frame): Likewise.
11873 * process.h (struct Lisp_Process): Likewise.
11874 * termhooks.h (struct terminal): Likewise.
11875 * window.c (struct save_window_data, struct saved_window): Likewise.
11876 * window.h (struct window): Likewise.
11877 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11878 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11879 * buffer.c (init_buffer_once): Likewise.
11880 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11882 * process.c (Fformat_network_address): Use local var for size,
11885 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11887 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11888 * data.c (atof): Remove decl; no longer used or needed.
11889 (digit_to_number): Move to lread.c.
11890 (Fstring_to_number): Use new string_to_number function, to be
11891 consistent with how the Lisp reader treats infinities and NaNs.
11892 Do not assume that floating-point numbers represent EMACS_INT
11893 without losing information; this is not true on most 64-bit hosts.
11894 Avoid double-rounding errors, by insisting on integers when
11895 parsing non-base-10 numbers, as the documentation specifies.
11896 * lisp.h (string_to_number): New decl, replacing ...
11897 (isfloat_string): Remove.
11898 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11899 (read1): Do not accept +. and -. as integers; this
11900 appears to have been a coding error. Similarly, do not accept
11901 strings like +-1e0 as floating point numbers. Do not report
11902 overflow for integer overflows unless the base is not 10 which
11903 means we have no simple and reliable way to continue.
11904 Break out the floating-point parsing into a new
11905 function string_to_number, so that Fstring_to_number parses
11906 floating point numbers consistently with the Lisp reader.
11907 (digit_to_number): Move here from data.c. Make it static inline.
11908 (E_CHAR, EXP_INT): Remove, replacing with ...
11909 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11910 (string_to_number): New function, replacing isfloat_string.
11911 This function checks for valid syntax and produces the resulting
11912 Lisp float number too. Rework it so that string-to-number
11913 no longer mishandles examples like "1.0e+". Use strtoumax,
11914 so that overflow for non-base-10 numbers is reported only when
11915 there's no portable and simple way to convert to floating point.
11917 * textprop.c (set_text_properties_1): Rewrite for clarity,
11918 and to avoid GCC warning about integer overflow.
11920 * intervals.h (struct interval): Use EMACS_INT for members
11921 where EMACS_UINT might cause problems. See
11922 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11923 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11924 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11926 (offset_intervals): Tell GCC not to worry about length overflow
11927 when negating a negative length.
11929 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11930 (overrun_check_free): Likewise.
11932 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11933 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11936 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11937 (gnutls_make_error): Rename local to avoid shadowing.
11938 (gnutls_emacs_global_deinit): ifdef out; not used.
11939 (Fgnutls_boot): Use const for pointer to readonly storage.
11940 Comment out unused local. Fix pointer signedness problems.
11942 * lread.c (openp): Don't stuff size_t into an 'int'.
11943 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11944 about possible signed overflow.
11946 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11947 (GDK_KEY_g): Don't define if already defined.
11948 (xg_prepare_tooltip): Avoid pointer signedness problem.
11949 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11951 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11952 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11954 * xfns.c (Fx_window_property): Simplify a bit,
11955 to make a bit faster and to avoid GCC 4.6.0 warning.
11956 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11958 * fns.c (internal_equal): Don't assume size_t fits in int.
11960 * alloc.c (compact_small_strings): Tighten assertion a little.
11962 Replace pEd with more-general pI, and fix some printf arg casts.
11963 * lisp.h (pI): New macro, generalizing old pEd macro to other
11964 conversion specifiers. For example, use "...%"pI"d..." rather
11965 than "...%"pEd"...".
11966 (pEd): Remove. All uses replaced with similar uses of pI.
11967 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11968 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11969 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11970 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11971 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11972 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11973 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11975 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11976 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11977 * print.c (safe_debug_print, print_object): Likewise.
11978 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11980 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11981 avoiding the 0 flag, which is not portable.
11982 * process.c (Fmake_network_process): Use pI to avoid cast.
11983 * region-cache.c (pp_cache): Likewise.
11984 * xdisp.c (decode_mode_spec): Likewise.
11985 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11986 behavior on 64-bit hosts with printf arg.
11987 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11988 (x_stop_queuing_selection_requests): Likewise.
11989 (x_get_window_property): Don't truncate byte count to an 'int'
11992 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11993 here, since it parses constructs like leading '-' and spaces,
11994 which are not wanted; and it overflows with large numbers.
11995 Instead, simply match F[0-9]+, which is what is wanted anyway.
11997 * alloc.c: Remove unportable assumptions about struct layout.
11998 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11999 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12000 (allocate_vectorlike, make_pure_vector): Use the new macros,
12001 plus offsetof, to remove unportable assumptions about struct layout.
12002 These assumptions hold on all porting targets that I know of, but
12003 they are not guaranteed, they're easy to remove, and removing them
12004 makes further changes easier.
12006 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12007 This doesn't fix a bug but makes the code clearer.
12008 (string_overrun_cookie): Now const. Use initializers that
12009 don't formally overflow signed char, to avoid warnings.
12010 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12011 can cause Emacs to crash when string overrun checking is enabled.
12012 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12013 multiple of sizeof (EMACS_INT); it need not be, if
12014 alignof(EMACS_INT) < sizeof (EMACS_INT).
12015 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12017 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12024 supposed to be handshaking. (Bug#8556)
12025 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12027 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

12032 (handle_user_signal): Break into debugger when debug-on-event
12033 matches the current signal symbol.
12035 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12037 * alloc.c (check_sblock, check_string_bytes)
12038 (check_string_free_list): Convert to standard C.
12040 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12042 * w32.c (emacs_gnutls_push): Fix typo.
12044 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12046 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12047 "cast to pointer from integer of different size".
12049 Improve doprnt and its use in verror. (Bug#8545)
12050 * doprnt.c (doprnt): Document the set of format control sequences
12051 supported by the function. Use SAFE_ALLOCA instead of always
12054 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12055 is one byte too soon. Don't use xrealloc; instead xfree and
12058 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12060 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12063 * gnutls.c: Renamed global_initialized to
12064 gnutls_global_initialized. Added internals for the
12065 :verify-hostname-error, :verify-error, and :verify-flags
12066 parameters of `gnutls-boot' and documented those parameters in the
12067 docstring. Start callback support.
12068 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12069 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12070 on error. Return error code.

12072 (emacs_gnutls_read): Likewise.
12073 (Fgnutls_boot): Return handshake error code.

12141 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12142 * doprnt.c: Include limits.h.
12143 (SIZE_MAX): New macro.
12144 (doprnt): Return a size_t value. 2nd arg is now size_t.
12145 Many local variables are now size_t instead of int or unsigned.
12146 Improve overflow protection. Support `l' modifier for integer
12147 conversions. Support %l conversion. Don't assume an EMACS_INT
12148 argument for integer conversions and for %c.
12150 * lisp.h (doprnt): Restore prototype.
12152 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12153 $(SRC)/character.h.
12155 * Makefile.in (base_obj): Add back doprnt.o.
12157 * deps.mk (doprnt.o): Add back prerequisites.
12158 (callint.o): Depend on character.h.
12160 * eval.c (internal_lisp_condition_case): Include the handler
12161 representation in the error message.
12162 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12163 when breaking from the loop.
12165 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12167 * callint.c (Fcall_interactively): When displaying error message
12168 about invalid control letter, pass the character's codepoint, not
12169 a pointer to its multibyte form. Improve display of the character
12170 in octal and display also its hex code.
12172 * character.c (char_string): Use %x to display the (unsigned)
12173 codepoint of an invalid character, to avoid displaying a bogus
12176 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12177 `error', not SYMBOL_NAME itself.
12179 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12180 character arguments to `error'.
12182 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12183 to `error' in error message about FINAL_CHAR argument. Make sure
12184 FINAL_CHAR is a character, and use %c when it is passed as
12185 argument to `error'.
12187 2011-04-23 Eli Zaretskii <eliz@gnu.org>

12375 ns_descriptor_to_entity that were caused by using free to
12376 deallocate memory blocks that were allocated by xmalloc (via
12377 xstrdup). This caused Emacs to crash when compiled with
12378 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

12397 (emacs_read, emacs_write): Use it.
12398 * process.c (send_process): Adjust to the new signatures of
12399 emacs_write and emacs_gnutls_write. Do not attempt to store

12735 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12736 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12737 exported only to the debugger.

12740 * atimer.h (run_all_atimers): Remove; not exported.
12742 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12743 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12744 was inaccessible from Lisp.
12745 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12746 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12748 alloc.c: Import and export fewer symbols, and remove unused items.
12749 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12751 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12752 it's not optimized away by whole-program optimization.

12754 (catchlist, handlerlist, mark_backtrace):
12755 Declare only if BYTE_MARK_STACK.

12764 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12765 (mark_backtrace): Define only if BYTE_MARK_STACK.
12766 * xdisp.c (message_enable_multibyte): Now static.
12768 Declare Lisp_Object Q* variables to be 'static' if not exported.
12769 This makes it easier for human readers (and static analyzers)
12770 to see whether these variables are used from other modules.
12771 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12772 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

12781 Remove decls of unexported vars.
12782 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12784 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12786 Make Emacs functions such as Fatom 'static' by default.
12787 This makes it easier for human readers (and static analyzers)
12788 to see whether these functions can be called from other modules.
12789 DEFUN now defines a static function. To make the function external
12790 so that it can be used in other C modules, use the new macro DEFUE.
12791 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12792 (Finit_image_library):
12793 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

12796 Remove decls, since these functions are now static.
12797 (Funintern, Fget_internal_run_time): New decls, since these functions
12798 were already external.
12800 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

12808 Mark functions with DEFUE instead of DEFUN,
12809 if they are used in other modules.
12810 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12811 decls for now-static functions.
12812 * buffer.h (Fdelete_overlay): Remove decl.

12848 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12850 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12851 when at ZV. (Bug#8487)
12853 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12855 * charset.c (Fclear_charset_maps): Use xfree instead of free.

12861 * xsettings.c (read_and_apply_settings): Likewise.
12863 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12864 (overrun_check_free): Protoize.
12866 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12868 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12869 since callers should never pass a negative size.
12870 Change the signature to match that of plain 'read' and 'write'; see
12871 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12872 * lisp.h: Update prototypes of emacs_write and emacs_read.
12874 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12876 * xdisp.c (redisplay_window): Don't try to determine the character
12877 position of the scroll margin if the window start point w->startp
12878 is outside the buffer's accessible region. (Bug#8468)
12880 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12882 Fix write-region and its subroutines for buffers > 2GB.
12883 * fileio.c (a_write, e_write): Modify declaration of arguments and
12884 local variables to support buffers larger than 2GB.
12885 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12887 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12888 argument, local variables, and return value.
12890 * lisp.h: Update prototypes of emacs_write and emacs_read.
12892 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12894 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12896 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12898 Fix more problems found by GCC 4.6.0's static checks.
12900 * xdisp.c (vmessage): Use a better test for character truncation.
12902 * charset.c (load_charset_map): <, not <=, for optimization,
12903 and to avoid potential problems with integer overflow.
12904 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12905 * casetab.c (set_identity, shuffle): Likewise.
12906 * editfns.c (Fformat): Likewise.
12907 * syntax.c (skip_chars): Likewise.
12909 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12910 This also lets GCC 4.6.0 generate slightly better loop code.
12912 * callint.c (Fcall_interactively): <, not <=, for optimization.
12913 (Fcall_interactively): Count the number of arguments produced,
12914 not the number of arguments given. This is simpler and lets GCC
12915 4.6.0 generate slightly better code.
12917 * ftfont.c: Distingish more carefully between FcChar8 and char.
12918 The previous code passed unsigned char * to a functions like
12919 strlen and xstrcasecmp that expect char *, which does not
12920 conform to the C standard.
12921 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12922 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12923 char * when the C standard requires it.
12925 * keyboard.c (read_char): Remove unused var.
12927 * eval.c: Port to Windows vsnprintf (Bug#8435).
12928 Include <limits.h>.
12929 (SIZE_MAX): Define if the headers do not.
12930 (verror): Do not give up if vsnprintf returns a negative count.
12931 Instead, grow the buffer. This ports to Windows vsnprintf, which
12932 does not conform to C99. Problem reported by Eli Zaretskii.
12933 Also, simplify the allocation scheme, by avoiding the need for
12934 calling realloc, and removing the ALLOCATED variable.
12936 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12938 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12939 But keep the doprint source code for now, as we might revamp it
12940 and use it again (Bug#8435).
12941 * lisp.h (doprnt): Remove.
12942 * Makefile.in (base_obj): Remove doprnt.o.
12943 * deps.mk (doprnt.o): Remove.
12945 error: Print 32- and 64-bit integers portably (Bug#8435).
12946 Without this change, on typical 64-bit hosts error ("...%d...", N)
12947 was used to print both 32- and 64-bit integers N, which relied on
12948 undefined behavior.
12949 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12950 * lisp.h (error, verror): Mark as printf-like functions.
12951 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12952 Report overflow in size calculations when allocating printf buffer.
12953 Do not truncate output string at its first null byte.
12954 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12955 Truncate the output at a character boundary, since vsnprintf does not
12957 * charset.c (check_iso_charset_parameter): Convert internal
12958 character to string before calling 'error', since %c now has the
12960 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12961 overflow when computing char to be passed to 'error'. Do not
12962 pass Lisp_Object to 'error'; pass the integer instead.
12963 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12964 formatted with plain %d.
12966 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12968 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12970 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12972 * xterm.c (x_catch_errors): Remove duplicate declaration.
12974 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12976 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12978 2011-04-10 Jim Meyering <meyering@redhat.com>
12980 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12981 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12982 return ssize_t not "int", and use size_t as the buffer length.
12983 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12984 * gnutls.h: Update declarations.
12985 * process.c (read_process_output): Use ssize_t, to match.
12986 (send_process): Likewise.
12988 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12990 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12992 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12994 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12995 Use unsigned char, to match FcChar8 type definition.
12997 * xterm.c (handle_one_xevent):
12998 * xmenu.c (create_and_show_popup_menu):
12999 * xselect.c (x_decline_selection_request)
13000 (x_reply_selection_request): Avoid type-punned deref of X events.
13002 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13004 Fix some uses of `int' instead of EMACS_INT.
13005 * search.c (string_match_1, fast_string_match)
13006 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13007 (scan_buffer, find_next_newline_no_quit)
13008 (find_before_next_newline, search_command, Freplace_match)
13009 (Fmatch_data): Make some `int' variables be EMACS_INT.
13011 * xdisp.c (display_count_lines): 3rd argument and return value now
13012 EMACS_INT. All callers changed.
13013 (pint2hrstr): Last argument is now EMACS_INT.
13015 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13016 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13017 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13028 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13029 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13031 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13032 (encode_invocation_designation): Last argument P_NCHARS is now
13034 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13035 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13037 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13040 * ccl.c (Fccl_execute_on_string): Declare some variables
13043 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13045 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13047 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13049 * process.c (Fformat_network_address): Doc fix.
13051 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13053 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13055 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13057 * keyboard.c (read_char): Call Lisp function help-form-show,
13058 instead of using internal_with_output_to_temp_buffer.
13059 (Qhelp_form_show): New var.
13060 (syms_of_keyboard): Use DEFSYM macro.
13062 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13073 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13075 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13077 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13079 Fix more problems found by GCC 4.6.0's static checks.
13081 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

13094 printf-like functions.
13095 (tiff_load): Add casts to remove these marks before passing them
13096 to system-supplied API.
13098 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13100 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13101 This avoids several warnings with gcc -Wstrict-overflow.
13102 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13103 directly, rather than having caller test rule sign. This avoids
13104 some unnecessary tests.
13105 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13106 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13107 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13109 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13110 (xfont_open): Avoid unnecessary tests.
13112 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13114 * composite.h, composite.c (composition_gstring_put_cache):
13115 Use EMACS_INT, not int, for length.
13117 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13118 breaking out part of COMPOSITION_DECODE_RULE.
13119 (COMPOSITION_DECODE_RULE): Use it.
13120 * composite.c (get_composition_id): Remove unused local vars,
13121 by using the new macro.
13123 * textprop.c (set_text_properties_1): Change while to do-while,
13124 since the condition is always true at first.
13126 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13127 (interval_deletion_adjustment): Return unsigned value.
13130 * process.c (list_processes_1, create_pty, read_process_output):
13131 (exec_sentinel): Remove vars that were set but not used.
13132 (create_pty): Remove unnecessary "volatile"s.
13133 (Fnetwork_interface_info): Avoid possibility of int overflow.
13134 (read_process_output): Do adaptive read buffering even if carryover.
13135 (read_process_output): Simplify nbytes computation if buffered.

13143 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13144 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13146 * print.c (print_error_message): Avoid int overflow.
13148 * font.c (font_list_entities): Redo for clarity,
13149 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13151 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13152 (font_score): Avoid potential overflow in diff calculation.
13154 * fns.c (substring_both): Remove var that is set but not used.
13155 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13157 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13159 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13160 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13161 can always succeed if overflow has undefined behavior.
13163 * search.c (boyer_moore, wordify): Remove vars set but not used.
13164 (wordify): Omit three unnecessary tests.
13166 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13167 All callers changed. This avoids the need for an unused var.

13171 * dired.c (file_name_completion): Remove var that is set but not used.
13173 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13175 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13176 (Finsert_file_contents): Remove unnecessary code checking fd.
13178 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13179 Check for integer overflow on size calculations.
13181 * buffer.c (Fprevious_overlay_change): Remove var that is set
13184 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13185 Remove vars that are set but not used.
13186 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13187 (timer_check_2): Mark vars as initialized.
13189 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13191 * image.c (lookup_image): Remove var that is set but not used.
13192 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13194 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13195 that are set but not used.
13197 * xfns.c (make_invisible_cursor): Don't return garbage
13198 if XCreateBitmapFromData fails (Bug#8410).
13200 * xselect.c (x_get_local_selection, x_handle_property_notify):
13201 Remove vars that are set but not used.
13203 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13204 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13206 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13207 Remove var that is set but not used.
13208 (scroll_bar_windows_size): Now size_t, not int.
13209 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13210 Check for overflow.
13212 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13213 (map_tty_color) [!defined MSDOS]: Likewise.
13215 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13217 * coding.c: Remove vars that are set but not used.
13218 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13219 All callers changed.
13220 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13221 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13222 (decode_coding_charset): Remove vars that are set but not used.
13224 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13225 that is set but not used.
13227 * print.c (print_object): Remove var that is set but not used.
13229 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13230 The gnulib version avoids calling malloc in the usual case,
13231 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13232 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13233 * filelock.c (current_lock_owner): Likewise.
13234 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13235 * sysdep.c: Include allocator.h, careadlinkat.h.
13236 (emacs_no_realloc_allocator): New static constant.
13237 (emacs_readlink): New function.
13238 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13239 ../lib/careadlinkat.h.
13241 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13243 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13244 first non-nil return value).
13246 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13248 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13249 if not defined (Bug#8403).
13251 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13253 * xdisp.c (display_count_lines): Remove parameter `start',
13254 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13255 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13256 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13258 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13259 and thereabouts. All callers changed.
13260 (get_per_char_metric): Remove parameter `f', unused since
13261 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13263 2011-04-02 Jim Meyering <meyering@redhat.com>
13265 do not dereference NULL upon failed strdup
13266 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13267 (ns_get_family): Likewise.
13269 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13271 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13273 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13275 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13278 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13280 Add lexical binding.
13282 * window.c (Ftemp_output_buffer_show): New fun.
13283 (Fsave_window_excursion):
13284 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13286 * lread.c (lisp_file_lexically_bound_p): New function.
13287 (Fload): Bind Qlexical_binding.
13288 (readevalloop): Remove `evalfun' arg.
13289 Bind Qinternal_interpreter_environment.
13290 (Feval_buffer): Bind Qlexical_binding.
13291 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13293 (syms_of_lread): Declare `lexical-binding'.
13295 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13297 * keyboard.c (eval_dyn): New fun.
13298 (menu_item_eval_property): Use it.
13300 * image.c (parse_image_spec): Use Ffunctionp.
13302 * fns.c (concat, mapcar1): Accept byte-code-functions.
13304 * eval.c (Fsetq): Handle lexical vars.
13305 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13306 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13307 (FletX, Flet): Obey lexical binding.
13308 (Fcommandp): Handle closures.
13309 (Feval): New `lexical' arg.
13310 (eval_sub): New function extracted from Feval. Use it almost
13311 everywhere where Feval was used. Look up vars in lexical env.
13313 (Ffunctionp): Move from subr.el.
13314 (Ffuncall): Handle closures.
13315 (apply_lambda): Remove `eval_flags'.
13316 (funcall_lambda): Handle closures and new byte-code-functions.
13317 (Fspecial_variable_p): New function.
13318 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13319 but without exporting it to Lisp.
13321 * doc.c (Fdocumentation, store_function_docstring):
13322 * data.c (Finteractive_form): Handle closures.
13324 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13327 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13329 (exec_byte_code): New function extracted from Fbyte_code to handle new
13330 calling convention for byte-code-functions. Add new byte-codes.
13332 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13334 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13336 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13338 * xdisp.c (redisplay_internal): Fix prototype.
13340 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13342 * xdisp.c (SCROLL_LIMIT): New macro.
13343 (try_scrolling): Use it when setting scroll_limit.
13344 Limit scrolling to 100 screen lines.
13345 (redisplay_window): Even when falling back on "recentering",
13346 position point in the window according to scroll-conservatively,
13347 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13349 (try_scrolling): When point is above the window, allow searching
13350 as far as scroll_max, or one screenful, to compute vertical
13351 distance from PT to the scroll margin position. This prevents
13352 try_scrolling from unnecessarily failing when
13353 scroll-conservatively is set to a value slightly larger than the
13354 window height. Clean up the case of PT below the margin at bottom
13355 of window: scroll_max can no longer be INT_MAX. When aggressive
13356 scrolling is in use, don't let point enter the opposite scroll
13357 margin as result of the scroll.
13358 (syms_of_xdisp) <scroll-conservatively>: Document the
13359 threshold of 100 lines for never-recentering scrolling.
13361 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13363 * dispextern.h (move_it_by_lines):
13364 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

13366 (message_log_check_duplicate): Remove parameters `prev_bol' and
13367 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13368 (redisplay_internal): Remove parameter `preserve_echo_area',
13369 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13371 * indent.c (Fvertical_motion):
13372 * window.c (window_scroll_pixel_based, Frecenter):
13373 Don't pass `need_y_p' to `move_it_by_lines'.
13375 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13377 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13378 steal a few bits to be more compact.
13379 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13380 Remove unneeded casts.
13382 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13384 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13386 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13387 binding" message (bug#7967).
13389 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13391 Fix more problems found by GCC 4.6.0's static checks.
13393 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13394 Remove unused local var.
13396 * editfns.c (Fmessage_box): Remove unused local var.
13398 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13399 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13400 Omit unused local vars.
13401 * window.c (shrink_windows): Omit unused local var.
13402 * menu.c (digest_single_submenu): Omit unused local var.
13403 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13404 Omit unused local var.
13406 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13407 Don't assume string length fits in int.
13408 (keyremap_step, read_key_sequence): Use size_t for sizes.
13409 (read_key_sequence): Don't check last_real_key_start redundantly.
13411 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13412 instead of alloca (Bug#8344).
13414 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13415 (Fbacktrace_frame): Don't assume nframes fits in int.
13417 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13419 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13422 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13424 * cm.c (calccost): Turn while-do into do-while, for clarity.
13426 * keyboard.c (syms_of_keyboard): Use the same style as later
13427 in this function when indexing through an array. This also
13428 works around GCC bug 48267.
13430 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13432 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13434 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13435 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13437 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13438 This avoids undefined behavior on integer overflow, and is a bit
13439 more convenient anyway since it is compared to a size_t variable.
13441 Variadic C functions now count arguments with size_t, not int.
13442 This avoids an unnecessary limitation on 64-bit machines, which
13443 caused (substring ...) to crash on large vectors (Bug#8344).
13444 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13445 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13453 * fns.c (concat): Likewise.
13454 * frame.c (x_set_frame_parameters): Likewise.
13455 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13456 0 if not found, not -1. All callers changed.
13458 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13459 (stack_copy_size): Now size_t, not int.
13460 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13462 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13464 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13465 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13466 All callers changed.
13468 * lisp.h (multibyte_char_to_unibyte):
13469 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13470 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13478 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13480 * keyboard.c (safe_run_hook_funcall): New function.
13481 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13482 don't set the hook to nil, but remove the offending function instead.
13483 (Qcommand_hook_internal): Remove, unused.
13484 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13485 Vcommand_hook_internal.
13487 * eval.c (enum run_hooks_condition): Remove.
13488 (funcall_nil, funcall_not): New functions.
13489 (run_hook_with_args): Call each function through a `funcall' argument.
13490 Remove `cond' argument, now redundant.
13491 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13492 (Frun_hook_with_args_until_failure): Adjust accordingly.
13493 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

13503 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13504 All callers changed.
13506 * w32.c (_wsa_errlist): Use braces for struct initializers.
13508 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13509 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13510 All callers changed.

13666 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13668 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13669 unconditionally since it does the check itself.
13671 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13673 Fix more problems found by GCC 4.5.2's static checks.
13675 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13676 the first time through the loop, since we know p0 < p1 then.
13677 This also avoids a gcc -Wstrict-overflow warning.
13679 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13680 leading to a memory leak, possible in functions like
13681 load_charset_map_from_file that can allocate an unbounded number
13682 of objects (Bug#8318).
13684 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13685 that could (at least in theory) be that large.
13687 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13688 This is less likely to overflow, and avoids undefined behavior if
13689 overflow does occur. All callers changed. Use strtoul to scan
13690 for the unsigned long integer.
13691 (pint2hrstr): Simplify and tune code slightly.
13692 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13702 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13705 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13707 * process.c (Fmake_network_process): Use socklen_t, not int,
13708 where POSIX says socklen_t is required in portable programs.
13709 This fixes a porting bug on hosts like 64-bit HP-UX, where
13710 socklen_t is wider than int (Bug#8277).
13711 (Fmake_network_process, server_accept_connection):
13712 (wait_reading_process_output, read_process_output):
13715 * process.c: Rename or move locals to avoid shadowing.

13725 Make tparam.h and terminfo.c consistent.
13726 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13727 Include tparam.h instead, since it declares them.
13728 * cm.h (PC): Remove extern decl; tparam.h now does this.
13729 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13730 * terminfo.c: Include tparam.h, to check interfaces.
13731 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13732 (tparam): Adjust signature to match interface in tparam.h;
13733 this removes some undefined behavior. Check that outstring and len
13734 are zero, which they always are with Emacs.
13735 * tparam.h (PC, BC, UP): New extern decls.
13737 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13738 (xftfont_open): Rename locals to avoid shadowing.
13740 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

13752 * composite.c (composition_compute_stop_pos): Rename local to
13754 (composition_reseat_it): Remove unused locals.
13755 (find_automatic_composition, composition_adjust_point): Likewise.
13756 (composition_update_it): Mark var as initialized.
13757 (find_automatic_composition): Mark vars as initialized,
13758 with a FIXME (Bug#8290).

13762 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13763 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13764 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13765 to avoid shadowing.
13767 * textprop.c (property_change_between_p): Remove; unused.
13769 * intervals.c (interval_start_pos): Now static.
13771 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13777 Fix pointer signedness.
13778 (alsa_choose_format): Remove unused local var.
13779 (wav_play): Initialize a variable to 0, to prevent undefined
13780 behavior (Bug#8278).
13782 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13784 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13786 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13787 clobbering (Bug#8298).
13788 * sysdep.c (sys_subshell): Likewise.
13789 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13791 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13792 This should get cleaned up, so that child_setup has the
13793 same signature on all platforms.
13795 * callproc.c (call_process_cleanup): Now static.
13796 (relocate_fd): Rename locals to avoid shadowing.
13798 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13800 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13801 not to be necessary, and produces flickering.
13803 2011-03-20 Glenn Morris <rgm@gnu.org>
13805 * config.in: Remove file.
13807 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13809 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13810 are now in src/globals.h.
13811 (syms_of_minibuf): Remove spurious & from previous change.

13837 (sigchld_handler): Now static.
13839 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13840 That way, the code declares only the vars that it needs.

13850 (CONSTANTLIM): Remove; unused.
13851 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13852 Define only if needed.
13854 * unexelf.c (unexec): Name an expression,
13855 to avoid gcc -Wbad-function-cast warning.
13856 Use a different way to cause a compilation error if anyone uses
13857 n rather than nn, a way that does not involve shadowing.
13858 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13860 * deps.mk (unexalpha.o): Remove; unused.
13862 New file unexec.h, the (simple) interface for unexec (Bug#8267).

13937 ENABLE_CHECKING is not defined.
13939 * data.c (Findirect_variable): Name an expression, to avoid
13940 gcc -Wbad-function-cast warning.

13982 (regex_compile, re_match_2_internal): Mark locals as initialized.
13983 (RETALLOC_IF): Define only if needed.
13984 (WORDCHAR_P): Likewise. This one is never needed, but is used
13985 only in a comment talking about a compiler bug, so put inside
13986 the #if 0 of that comment.
13987 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13988 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13991 * search.c (boyer_moore): Rename locals to avoid shadowing.

14016 gcpro1, gcpro2, etc.
14017 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14019 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14020 argument, for consistency with GCPRO2_VAR, etc: it is now the

14024 Rename locals to avoid shadowing.
14026 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14027 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14028 dired.c's scmp function, had undefined behavior.

14030 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14031 * buffer.h: ... to here, because these macros use current_buffer,
14032 and the new implementation with inline functions needs to have
14033 current_buffer in scope now, rather than later when the macros
14035 (downcase, upcase1): New static inline functions.
14036 (DOWNCASE, UPCASE1): Reimplement using these functions.
14037 This avoids undefined behavior in expressions like
14038 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14039 from race conditions in accessing the global variables
14040 case_temp1 and case_temp2.
14041 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

14052 (file_name_as_directory): Use const pointers when appropriate.
14053 (Fexpand_file_name): Likewise. In particular, newdir might
14054 point at constant storage, so make it a const pointer.

14058 (Fset_file_times, Finsert_file_contents, auto_save_error):

14063 to avoid shadowing.
14065 * marker.c (bytepos_to_charpos): Remove; unused.
14067 * lisp.h (verify_bytepos, count_markers): New decls,
14068 so that gcc does not warn that these functions aren't declared.

14071 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14072 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14073 (copy_text): Remove unused local var.

14078 * buffer.c (fix_overlays_before): Mark locals as initialized.
14079 (fix_start_end_in_overlays): Likewise. This function should be
14080 simplified by using pointers-to-pointers, but that's a different
14082 (switch_to_buffer_1): Now static.
14083 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14084 (report_overlay_modification): Rename locals to avoid shadowing.

14087 Fix pointer signedness issue.
14088 (sys_subshell): Mark local as volatile if checking for lint,
14089 to suppress a gcc -Wclobbered warning that does not seem to be right.
14090 (MAXPATHLEN): Define only if needed.
14092 * process.c (serial_open, serial_configure): Move decls from here ...
14093 * systty.h: ... to here, so that they can be checked.
14095 * fns.c (get_random, seed_random): Move extern decls from here ...
14096 * lisp.h: ... to here, so that they can be checked.
14098 * sysdep.c (reset_io): Now static.
14099 (wait_for_termination_signal): Remove; unused.
14101 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

14107 (describe_map_tree):
14108 Rename locals to avoid shadowing.
14110 * keyboard.c: Declare functions static if they are not used elsewhere.
