32 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
33
34 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
35 Suggested by Stefan Monnier in
36 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
37 * alloc.c (widen_to_Lisp_Object): New static function.
38 (mark_memory): Also mark Lisp_Objects by fetching pointer words
39 and widening them to Lisp_Objects. This would work even if
40 USE_LSB_TAG is defined and wide integers are used, which might
41 happen in a future version of Emacs.
42
43 2012-02-25 Chong Yidong <cyd@gnu.org>
44
45 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

50 before saving to clipboard manager.
51
52 2012-02-24 Chong Yidong <cyd@gnu.org>
53

59 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
60 call when setting menu-bar-lines and tool-bar-lines parameters.
61 (unwind_create_frame_1): New helper function.

82 when computing $valmask.
83
84 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
85 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
86 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
87 It's useless in that case, and it can cause problems on hosts
88 that allocate halves of EMACS_INT values separately.
89 Reported by Dan Horák. Diagnosed by Andreas Schwab in
90 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
91 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
92 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
93 it avoids undefined behavior on hosts where shifting right by more
94 than the word width has undefined behavior.
95
96 2012-02-19 Chong Yidong <cyd@gnu.org>
97
98 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

135
136 2012-02-12 Chong Yidong <cyd@gnu.org>
137
138 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
139 as that creates a dangerous corner case.
140
141 * window.c (Fdelete_window_internal): Invalidate the mouse
142 highlight (Bug#9904).
143
144 2012-02-12 Glenn Morris <rgm@gnu.org>

220 * character.c (char_width): Return EMACS_INT, not int.
221 (char_width, c_string_width): Check for overflow when
222 computing the width; this is possible now that individual
223 characters can have unbounded width. Problem introduced
224 by merge from Emacs 23 on 2012-01-19.
225
226 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

247
248 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
249 NULL (Bug#6988).
250 (x_produce_glyphs): If the component of a composition is a null
251 string, set it->pixel_width to 1 to avoid zero-width glyph.
252
253 2012-02-01 Eli Zaretskii <eliz@gnu.org>
254
255 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its

257 output from a subprocess an order of magnitude faster on
258 MS-Windows, where all sbrk'ed memory is always contiguous.

716
717 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.

873 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
874 Otherwise, valgrind does not work on some platforms.
875 Problem reported by Andreas Schwab in
876 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
877 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
878 is set, removing the need for VIRT_ADDRESS_VARIES.
879 (PURE_P): Use a more-efficient implementation that needs just one
880 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
881 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
882 to 4 (xorl, subq, cmpq, setbe).
883 * alloc.c (pure): Always extern now, since that's the
884 VIRT_ADDR_VARIES behavior.
885 (PURE_POINTER_P): Use a single comparison, not two, for
886 consistency with the new puresize.h.
887 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
888 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
889 Remove VIRT_ADDR_VARIES no longer needed.

894 (erase_phys_cursor, update_window_cursor, show_mouse_face)
895 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
896 behave as if the cursor position were at the window margin.
897
898 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
899 and the cursor position is out of bounds, behave as if the cursor
900 position were at the window margin. (Bug#10075)

972
973 * xdisp.c (display_line): Move the call to
974 highlight_trailing_whitespace before the call to
975 compute_line_metrics, since the latter needs to see the final
976 faces of all the glyphs to compute ROW's hash value.
977 Fixes assertion violations in row_equal_p. (Bug#10035)
978
979 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

985
986 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs

1119 (window_box_right, window_box_right_offset): Declare extern.
1120 Otherwise, these inline functions do not conform to C99 and
1121 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
1122 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.

1330 2011-10-28 Eli Zaretskii <eliz@gnu.org>
1331
1332 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
1333 possible random value that matches one of those tested as
1334 condition to clear the mouse face.
1335
1336 2011-10-28 Chong Yidong <cyd@gnu.org>
1337

1352 2011-10-28 Eli Zaretskii <eliz@gnu.org>
1353
1354 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
1355 <oslsachem@gmail.com> for helping to debug this.
1356
1357 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

1360 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
1361 (GetGlyphOutlineW_Proc): New typedefs.
1362 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
1363 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
1364 New functions.
1365 (w32font_open_internal, compute_metrics):
1366 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
1367 instead of calling the "wide" APIs directly.
1368
1369 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
1370
1371 * w32.h (syms_of_w32font): Add prototype.
1372
1373 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

1377 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
1378 (Fmove_to_window_line): Doc fix.
1379
1380 2011-10-27 Chong Yidong <cyd@gnu.org>
1381
1382 * process.c (make_process): Set gnutls_state to NULL.
1383
1384 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
1385 non-NULL, regardless of GNUTLS_INITSTAGE.
1386 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
1387 an error. Set process slots as soon as we allocate them.
1388
1389 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
1390
1391 2011-10-27 Chong Yidong <cyd@gnu.org>
1392
1393 * gnutls.c (emacs_gnutls_deinit): New function.
1394 Deallocate credentials structures as well as calling gnutls_deinit.
1395 (Fgnutls_deinit, Fgnutls_boot): Use it.
1396
1397 * process.c (make_process): Initialize GnuTLS credentials to NULL.
1398 (deactivate_process): Call emacs_gnutls_deinit.

1412
1413 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
1414
1415 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
1416
1417 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
1418

1421
1422 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
1423

1425 terminal (Bug#6649).
1426
1427 2011-10-20 Eli Zaretskii <eliz@gnu.org>
1428
1429 * dispextern.h (struct bidi_it): New member next_en_type.
1430
1431 * bidi.c (bidi_line_init): Initialize the next_en_type member.
1432 (bidi_resolve_explicit_1): When next_en_pos is valid for the
1433 current character, check also for next_en_type being WEAK_EN.
1434 (bidi_resolve_weak): Don't enter the expensive loop if the current
1435 position is before next_en_pos. Record the bidi type of the first
1436 non-ET, non-BN character we find, in addition to its position.
1437 (bidi_level_of_next_char): Invalidate next_en_type when
1438 next_en_pos is over-stepped.
1439
1440 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
1441
1442 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
1443 * editfns.c: Rewrite current-time-zone so that it invokes
1444 the equivalent of (format-time-string "%Z") to get the time zone name.
1445 This fixes a bug when the time zone name contains characters that
1446 need converting from the system time locale to Emacs internal format.
1447 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
1448 that patch fixed format-time-string to do the conversion, but
1449 I forgot to fix current-time-zone.
1450 (format_time_string): New function, containing most of
1451 what Fformat_time_string used to contain.
1452 (Fformat_time_string): Rewrite in terms of format_time_string.
1453 This doesn't change this function's behavior.
1454 (current-time-zone): Rewrite to use format_time_string.
1455 This fixes the bug reported by Michael Schierl in
1456 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
1457 Jason Rumney's 2007-06-07 change worked around this bug, but
1458 didn't fix it.
1459 * systime.h (tzname, timezone): Remove no-longer-used declarations.
1460
1461 2011-10-19 Eli Zaretskii <eliz@gnu.org>
1462
1463 * xdisp.c (start_display): If the character at POS is displayed
1464 via a display vector, reset IT->current.dpvec_index to zero.
1465 (try_window_reusing_current_matrix): If a line ends in a display
1466 vector or the next line starts in a display vector, continue
1467 redrawing the window even though the character position of
1468 start_row was reached.
1469 (Bug#9771, part 2)
1470
1471 2011-10-18 Chong Yidong <cyd@gnu.org>
1472
1473 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
1474 with nobreak-char-display too.
1475
1476 2011-10-18 Eli Zaretskii <eliz@gnu.org>
1477
1478 Fix part 3 of bug#9771.
1479 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
1480 (bidi_resolve_neutral): Don't enter the expensive loop looking for
1481 non-neutral characters if the current character is a paragraph
1482 separator (a.k.a. Newline). This avoids running the same
1483 expensive loop twice, once when we consume the preceding newline
1484 and the other time when the line actually needs to be displayed.
1485 Avoid the loop when we see neutrals on the base embedding level
1486 following a character whose directionality is the same as the
1487 paragraph's. This avoids running the expensive loop when a line
1488 ends in a long sequence of neutrals, like control characters.
1489 Add assertion against STRONG_AL type. Slightly rearrange code
1490 that determines the type of a neutral given the first non-neutral
1491 that follows it.
1492 (bidi_level_of_next_char): Set next_en_pos to zero when
1493 invalidating its info.
1494
1495 2011-10-17 Eli Zaretskii <eliz@gnu.org>
1496
1497 * xdisp.c (push_display_prop): Determine whether to record string
1498 or buffer position by IT->string, not by IT->method. Allow
1499 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
1500 (move_it_vertically_backward): Don't look for character position
1501 immediately after the newline when in a continuation line.
1502 (Bug#9771, part 1)
1503
1504 2011-10-15 Martin Rudalics <rudalics@gmx.at>
1505
1506 * window.c (coordinates_in_window): Rewrite and delabelize
1507 vertical border check. (Bug#5357) (Bug#9618)
1508
1509 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
1510
1511 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
1512 errors in XSetWindowBorder (bug#9310).
1513
1514 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
1515
1516 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
1517 avoid crash when xmalloc overrun checking is enabled.
1518
1519 2011-10-13 Eli Zaretskii <eliz@gnu.org>
1520
1521 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
1522 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
1523 cursor motion with <left> and <right> arrow keys.
1524
1525 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
1526 some callers set that themselves.
1527
1528 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1529
1530 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
1531 display string and the previous row comes from the same string and
1532 is empty. (Bug#9739) (Bug#9738)
1533
1534 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
1535
1536 * doc.c (get_doc_string): Encode file name (bug#9735).
1537
1538 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1539
1540 * bidi.c (bidi_level_of_next_char):
1541 * xdisp.c (get_visually_first_element): Remove old incorrect
1542 comments regarding the Unicode Line Separator character.
1543
1544 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
1545
1546 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
1547
1548 * alloc.c (Fgc_status): Do not access beyond zombies array
1549 boundary if nzombies > MAX_ZOMBIES.
1550 * alloc.c (dump_zombies): Add missing format specifier.
1551
1552 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
1553
1554 * xdisp.c (set_cursor_from_row): Simplify conditionals,
1555 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
1556
1557 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
1558 Some packages use them to denote characters with modifiers.
1559
1560 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
1561
1562 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
1563 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
1564 matching a pp-number. Rename parameter var to var1.
1565
1566 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
1567
1568 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
1569
1570 2011-10-08 Glenn Morris <rgm@gnu.org>
1571
1572 * callint.c (Fcall_interactively): Give a more explicit error for the
1573 'c' case with a non-character input. (Bug#8479)
1574
1575 2011-10-08 Eli Zaretskii <eliz@gnu.org>
1576
1577 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
1578 lines.
1579 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
1580 lines that are hscrolled on the left.
1581
1582 * dispnew.c (buffer_posn_from_coords): Account for a possible
1583 presence of header-line. (Bug#4426)
1584
1585 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
1586
1587 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
1588 Don't advertise functionality which we discourage or doesn't work.
1589
1590 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
1591
1592 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
1593 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
1594 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
1595 this makes Emacs dump core during garbage collection on rare
1596 occasions. sizeof is obviously inferior to offsetof here, so
1597 stick with offsetof.
1598 (GC_POINTER_ALIGNMENT): New macro.
1599 (mark_memory): Omit 3rd (offset) arg; caller changed.
1600 Don't assume EMACS_INT alignment is the same as pointer alignment.
1601
1602 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
1603
1604 * keyboard.c (read_key_sequence_remapped): New var.
1605 (read_key_sequence): Compute remapping in the right buffer.
1606 (command_loop_1): Use read_key_sequence's remapping directly.
1607
1608 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1609
1610 * dired.c (file_name_completion): Don't expand file name.
1611 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
1612 before checking file name handler.
1613
1614 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
1615 they've been requested explicitly (bug#9591).
1616
1617 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
1618
1619 * keymap.c (Fsingle_key_description): Use make_specified_string
1620 instead of build_string to build string from push_key_description.
1621 (Bug#5193)
1622
1623 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1624
1625 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
1626 This fixes a Y2038 bug on 64-bit hosts.
1627 * buffer.c (reset_buffer):
1628 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
1629 (Fclear_buffer_auto_save_failure):
1630 Use 0, not -1, to represent an unset failure time, since time_t
1631 might not be signed.
1632
1633 Remove dependency on glibc malloc internals.
1634 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1635 Move back here from lisp.h, but with their new implementations.
1636 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1637 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
1638 * charset.c (charset_table_init): New static var.
1639 (syms_of_charset): Use it instead of xmalloc. This removes a
1640 dependency on glibc malloc internals. See Eli Zaretskii's comment in
1641 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
1642 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1643 Move back to alloc.c.
1644 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1645 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
1646
1647 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
1648
1649 * nsterm.m (windowDidResize): Call x_set_window_size only when
1650 ns_in_resize is true. Otherwise set pixelwidth/height and
1651 call change_frame_size (Bug#9628).
1652
1653 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1654
1655 Port --enable-checking=all to Fedora 14 x86-64.
1656 * charset.c (syms_of_charset): Also account for glibc malloc's
1657 internal overhead when calculating the initial malloc maximum.
1658
1659 Port --enable-checking=all to Fedora 14 x86.
1660 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1661 Move to lisp.h.
1662 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
1663 (overrun_check_realloc, overrun_check_free):
1664 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
1665 That way, xmalloc returns a properly-aligned pointer even if
1666 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
1667 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
1668 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
1669 into account when calculating the initial malloc maximum.
1670 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1671 Move here from alloc.c, so that charset.c can use it too.
1672 Properly align; the old code wasn't right for common 32-bit hosts
1673 when configured with --enable-checking=all.
1674 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1675 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
1676
1677 2011-09-29 Eli Zaretskii <eliz@gnu.org>
1678
1679 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
1680 use EDOM.
1681
1682 2011-09-28 Eli Zaretskii <eliz@gnu.org>
1683
1684 * xdisp.c (compute_display_string_end): If there's no display
1685 string at CHARPOS, return -1.
1686
1687 * bidi.c (bidi_fetch_char): When compute_display_string_end
1688 returns a negative value, treat the character as a normal
1689 character not covered by a display string. (Bug#9624)
1690
1691 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
1692
1693 * lread.c (Fread_from_string): Fix typo in docstring.
1694
1695 2011-09-27 Eli Zaretskii <eliz@gnu.org>
1696
1697 * xdisp.c (handle_invisible_prop): If invisible text ends on a
1698 newline, reseat the iterator instead of bidi-iterating there one
1699 character at a time. (Bug#9610)
1700 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
1701 TO_CHARPOS if the bidi iterator is at base embedding level.
1702
1703 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
1704
1705 * lread.c (readevalloop): Use correct code for NBSP.
1706 (read1): Likewise. (Bug#9608)
1707
1708 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
1709
1710 * dbusbind.c (Fdbus_register_signal): When service is not
1711 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
1712
1713 2011-09-25 Glenn Morris <rgm@gnu.org>
1714
1715 * buffer.c (truncate-lines): Doc fix.

1720 (Fset_window_next_buffers): Doc fix.
1721
1722 2011-09-24 Glenn Morris <rgm@gnu.org>
1723
1724 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
1725
1726 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
1727
1728 Fix minor problems found by static checking.
1729 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.

1732 2011-09-24 Eli Zaretskii <eliz@gnu.org>
1733
1734 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
1735 Default value is now t. Doc fix.
1736
1737 * indent.c (Fvertical_motion): Compute and apply the overshoot
1738 logic when moving up, not only when moving down. Fix the
1739 confusing name and values of the it_overshoot_expected variable;
1740 logic changes accordingly. (Bug#9254) (Bug#9549)
1741
1742 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
1743 CHARPOS is covered by a display string which includes newlines.
1744 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
1745 is covered by a display string with embedded newlines.

1755
1756 do not ignore write error for any output size
1757 The previous change was incomplete.
1758 While it makes emacs --batch detect the vast majority of stdout
1759 write failures, errors were still ignored whenever the output size is
1760 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
1761 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
1762 && echo FAIL: ignored write error
1763 FAIL: ignored write error
1764 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
1765 && echo FAIL: ignored write error
1766 FAIL: ignored write error
1767 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
1768
1769 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
1770
1771 * emacs.c (Fkill_emacs): In noninteractive mode exit
1772 non-successfully if a write error occurred on stdout. (Bug#9574)
1773
1774 2011-09-21 Eli Zaretskii <eliz@gnu.org>
1775
1776 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
1777 the xassert test.
1778
1779 * dispextern.h (struct it): Update the comment documenting what
1780 can it->OBJECT be.
1781
1782 2011-09-20 Eli Zaretskii <eliz@gnu.org>
1783
1784 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
1785 a display string, extend search for cursor position to end of row.
1786 (find_row_edges): If the row ends in a newline from a display
1787 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
1788 Handle the case of a display string with multiple newlines.
1789 (Fcurrent_bidi_paragraph_direction): Fix search for previous
1790 non-empty line. Fixes confusing cursor motion with arrow keys at
1791 the beginning of a line that starts with whitespace.
1792
1793 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1794

1804
1805 * xdisp.c (display_line): Record maximum and minimum buffer
1806 positions even if no glyphs were produced (e.g., by a zero-width
1807 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
1808 buffer positions that will be removed from the glyph row because
1809 they don't fit.
1810 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
1811 column is beyond frame width: don't subtract 1 "pixel" when
1812 computing width of the stretch.
1813 (reseat_at_next_visible_line_start): Undo the change made on
1814 2011-09-17 that saved paragraph information and restored it after
1815 the call to `reseat'. (Bug#9545)
1816
1817 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1818
1819 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
1820 and turn window cursor on if cleared (Bug#9415).
1821
1822 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
1823
1824 * search.c (boyer_moore): Take unibyte characters from pattern
1825 literally. (Bug#9458)

1831 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
1832
1833 Fix minor problem found by static checking.
1834 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
1835 initialized, to pacify gcc -Wuninitialized.
1836
1837 * fileio.c: Report proper errno when syscall falls.
1838 (Finsert_file_contents): Save and restore errno,
1839 so that report_file_error outputs the correct diagnostic.
1840 (Fwrite_region) [CLASH_DETECTION]: Likewise.
1841
1842 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1843

1845
1846 2011-09-17 Eli Zaretskii <eliz@gnu.org>
1847
1848 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

1850
1851 2011-09-17 Eli Zaretskii <eliz@gnu.org>
1852
1853 * xdisp.c (reseat_at_next_visible_line_start): Keep information
1854 about the current paragraph and restore it after the call to reseat.
1855
1856 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
1857 (bidi_find_paragraph_start): Search back for paragraph beginning
1858 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
1859 (bidi_move_to_visually_next): Only trigger paragraph-related
1860 computations when the last character is a newline or at EOB, not
1861 just any NEUTRAL_B. (Bug#9470)
1862
1863 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
1864 truncated lines if point is covered by a display string. (Bug#9524)
1865
1866 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
1867
1868 * xselect.c: Relax test for outgoing X longs (Bug#9498).
1869 (cons_to_x_long): New function.
1870 (lisp_data_to_selection_data): Use it. Correct the test for
1871 short-versus-long data; it was negated. Break out of vector
1872 loop, for efficiency, when a long datum is discovered.
1873
1874 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
1875
1876 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
1877
1878 2011-09-16 Eli Zaretskii <eliz@gnu.org>
1879
1880 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
1881 GCC PR/17406) by declaring this function with external scope.
1882
1883 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
1884
1885 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
1886 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
1887
1888 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
1889

1903
1904 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
1905 This occurs when processing a multibyte format.
1906 Problem reported by Wolfgang Jenker.
1907
1908 2011-09-15 Johan Bockgård <bojohan@gnu.org>
1909

1912
1913 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
1914
1915 Remove unused external symbols.

1922
1923 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
1924
1925 * xselect.c: Use signed conversions more consistently (Bug#9498).
1926 (selection_data_to_lisp_data): Assume incoming selection data are
1927 signed integers, not unsigned. This is to be consistent with
1928 outgoing selection data, which was modified to use signed integers
1929 in as part of the fix to Bug#9196 in response to Jan D.'s comment
1930 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
1931 expects long, not unsigned long.
1932
1933 2011-09-14 Eli Zaretskii <eliz@gnu.org>
1934
1935 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect

1954 * minibuf.c (Fread_from_minibuffer): Doc fix.
1955
1956 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1957
1958 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
1959 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
1960
1961 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
1962
1963 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
1964 value for non-existent files.
1965
1966 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1967
1968 * fileio.c (Finsert_file_contents): If the file cannot be opened,
1969 set its "size" to -1. This will set the modtime_size field of
1970 the corresponding buffer to -1, which is what
1971 verify-visited-file-modtime expects for files that do not exist.
1972 (Bug#9139)
1973
1974 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
1975
1976 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
1977 here ...
1978 * lisp.h: ... from here. push_key_description is no longer
1979 defined in keyboard.c, so its declaration should not be in
1980 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
1981 logically belongs with push_key_description.
1982
1983 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
1984
1985 * buffer.h: Include <sys/types.h> instead of <time.h>.
1986 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
1987 Problem reported by Herbert J. Skuhra.

2002 redisplay in small windows.
2003
2004 2011-09-09 Eli Zaretskii <eliz@gnu.org>
2005

2009
2010 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
2011 Operate on live windows only.
2012
2013 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
2014
2015 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.

2017 2011-09-07 Eli Zaretskii <eliz@gnu.org>
2018

2026 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2027
2028 isnan: Fix porting problem to Solaris 10 with bundled gcc.
2029 Without this fix, the command to link temacs failed due to an
2030 undefined symbol __builtin_isnan. This is because
2031 /usr/include/iso/math_c99.h #defines isnan(x) to
2032 __builtin_isnan(x), but the bundled gcc, which identifies itself
2033 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
2034 a __builtin_isnan.
2035 * floatfns.c (isnan): #undef, and then #define to a clone of
2036 what's in data.c.
2037 (Fisnan): Always define, since it's always available now.
2038 (syms_of_floatfns): Always define isnan at the Lisp level.
2039
2040 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2041
2042 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
2043
2044 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2045
2046 * fileio.c: Fix bugs with large file offsets (Bug#9428).
2047 The previous code assumed that file offsets (off_t values) fit in
2048 EMACS_INT variables, which is not true on typical 32-bit hosts.
2049 The code messed up by falsely reporting buffer overflow in cases
2050 such as (insert-file-contents "big" nil 1 2) into an empty buffer
2051 when "big" contains more than 2**29 bytes, even though this
2052 inserts just one byte and does not overflow the buffer.
2053 (Finsert_file_contents): Store file offsets as off_t
2054 values, not as EMACS_INT values. Check for overflow when
2055 converting between EMACS_INT and off_t. When checking for
2056 buffer overflow or for overlap, take the offsets into account.
2057 Don't use EMACS_INT for small values where int suffices.
2058 When checking for overlap, fix a typo: ZV was used where
2059 ZV_BYTE was intended.
2060 (Fwrite_region): Don't assume off_t fits into 'long'.
2061 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
2062
2063 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
2064
2065 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
2066
2067 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2068
2069 sprintf-related integer and memory overflow issues (Bug#9412).
2070
2071 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
2072 (esprintf, exprintf, evxprintf): New functions.
2073 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
2074 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
2075 (modify_event_symbol): Do not assume that the length of
2076 name_alist_or_stem is safe to alloca and fits in int.
2077 (Fexecute_extended_command): Likewise for function name and binding.
2078 (Frecursion_depth): Wrap around reliably on integer overflow.
2079 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
2080 since some callers pass EMACS_INT values.
2081 (Fsingle_key_description): Don't crash if symbol name contains more
2082 than MAX_ALLOCA bytes.
2083 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
2084 (get_minibuffer): Arg is now EMACS_INT, not int.
2085 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
2086 (esprintf, exprintf, evxprintf): New decls.
2087 * window.h (command_loop_level, minibuf_level): Reflect API changes.
2088
2089 * dbusbind.c (signature_cat): New function.
2090 (xd_signature, Fdbus_register_signal):
2091 Do not overrun buffer; instead, report string overflow.
2092
2093 * dispnew.c (add_window_display_history): Don't overrun buffer.
2094 Truncate instead; this is OK since it's just a log.
2095
2096 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
2097 even if the time zone offset is outlandishly large.
2098 Don't mishandle offset == INT_MIN.
2099
2100 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
2101 when creating daemon; the previous buffer-overflow check was incorrect.
2102
2103 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
2104 which has the guts of the old verror function.
2105
2106 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
2107 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
2108
2109 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
2110 (font_unparse_xlfd): Don't blindly alloca long strings.
2111 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
2112 fits in int, when using sprintf. Use single snprintf to count
2113 length of string rather than counting it via multiple sprintfs;
2114 that's simpler and more reliable.
2115 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
2116 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
2117 sprintf, in case result does not fit in int.
2118
2119 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
2120 (fontset_from_font): Print it.
2121
2122 * frame.c (tty_frame_count): Now printmax_t, not int.
2123 (make_terminal_frame, set_term_frame_name): Print it.
2124 (x_report_frame_params): In X, window IDs are unsigned long,
2125 not signed long, so print them as unsigned.
2126 (validate_x_resource_name): Check for implausibly long names,
2127 and don't assume name length fits in 'int'.
2128 (x_get_resource_string): Don't blindly alloca invocation name;
2129 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
2130 not fit in int.
2131
2132 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
2133 (xg_check_special_colors, xg_set_geometry):
2134 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
2135
2136 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
2137 Use esprintf, not sprintf, in case result does not fit in int.
2138
2139 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2140 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
2141 it as a large positive number.
2142 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
2143 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2144
2145 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
2146 in case result does not fit in int.
2147
2148 * print.c (float_to_string): Detect width overflow more reliably.
2149 (print_object): Make sprintf buffer a bit bigger, to avoid potential
2150 buffer overrun. Don't assume list length fits in 'int'. Treat
2151 print length of 0 as 0, not as infinity; to be consistent with other
2152 uses of print length in this function. Don't overflow print length
2153 index. Don't assume hash table size fits in 'long', or that
2154 vectorlike size fits in 'unsigned long'.
2155
2156 * process.c (make_process): Use printmax_t, not int, to format
2157 process-name gensyms.
2158
2159 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
2160
2161 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
2162 to avoid potential buffer overrun.
2163
2164 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
2165 if X resource line is longer than 512 bytes.
2166
2167 * xfns.c (x_window): Make sprintf buffer a bit bigger
2168 to avoid potential buffer overrun.
2169
2170 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
2171
2172 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.

2175
2176 Integer overflow fixes for scrolling, etc.
2177 Without these, Emacs silently mishandles large integers sometimes.
2178 For example, "C-u 4294967297 M-x recenter" was treated as if
2179 it were "C-u 1 M-x recenter" on a typical 64-bit host.
2180
2181 * xdisp.c (try_window_id): Check Emacs fixnum range before
2182 converting to 'int'.
2183
2184 * window.c (window_scroll_line_based, Frecenter):
2185 Check that an Emacs fixnum is in range before assigning it to 'int'.
2186 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
2187 values converted from Emacs fixnums.
2188 (Frecenter): Don't wrap around a line count if it is out of 'int'
2189 range; instead, treat it as an extreme value.
2190 (Fset_window_configuration, compare_window_configurations):
2191 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
2192
2193 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
2194 that can exceed INT_MAX. Check that EMACS_INT value is in range
2195 before assigning it to the (possibly-narrower) index.
2196 (match_limit): Don't assume that a fixnum can fit in 'int'.
2197
2198 * print.c (print_object): Use ptrdiff_t, not int, for index that can
2199 exceed INT_MAX.
2200
2201 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
2202 (Fvertical_motion): Don't wrap around LINES values that don't fit
2203 in 'int'. Instead, treat them as extreme values. This is good
2204 enough for windows, which can't have more than INT_MAX lines anyway.
2205
2206 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
2207
2208 * Require libxml/parser.h to avoid compilation warning.
2209
2210 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
2211
2212 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
2213 since this reportedly can destroy thread storage.
2214
2215 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
2216
2217 * syntax.c (find_defun_start): Update all cache variables if
2218 exiting early (Bug#9401).
2219
2220 2011-08-30 Eli Zaretskii <eliz@gnu.org>
2221
2222 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
2223
2224 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
2225 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
2226 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
2227
2228 * term.c (tty_append_glyph): New function.
2229 (produce_stretch_glyph): Static function and its prototype deleted.
2230
2231 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
2232 Add prototypes.
2233
2234 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
2235
2236 * image.c (parse_image_spec): Check for nonnegative, not for positive,
2237 when checking :margin (Bug#9390).
2238 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
2239 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
2240 so that the name doesn't mislead. All uses changed.
2241
2242 2011-08-28 Johan Bockgård <bojohan@gnu.org>
2243
2244 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
2245 set_tty_hooks.
2246
2247 2011-08-27 Eli Zaretskii <eliz@gnu.org>
2248
2249 * xdisp.c (move_it_to): Don't bail out early when reaching
2250 position beyond to_charpos, if we are scanning backwards.
2251 (move_it_vertically_backward): When DY == 0, make sure we get to
2252 the first character in the line after the newline.
2253
2254 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
2255
2256 * ccl.c: Improve and simplify overflow checking (Bug#9196).
2257 (ccl_driver): Do not generate an out-of-range pointer.
2258 (Fccl_execute_on_string): Remove unnecessary check for
2259 integer overflow, noted by Stefan Monnier in
2260 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
2261 Remove a FIXME that didn't need fixing.
2262 Simplify the newly-introduced buffer reallocation code.
2263
2264 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
2265
2266 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
2267
2268 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
2269
2270 Integer and memory overflow issues (Bug#9196).
2271
2272 * doc.c (get_doc_string): Rework so that
2273 get_doc_string_buffer_size is the actual buffer size, rather than
2274 being 1 less than the actual buffer size; this makes xpalloc more
2275 convenient.
2276
2277 * image.c (x_allocate_bitmap_record, cache_image):
2278 * xselect.c (Fx_register_dnd_atom):
2279 Simplify previous changes by using xpalloc.
2280
2281 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
2282 since either will do and ptrdiff_t is convenient with xpalloc.
2283
2284 * charset.c (charset_table_size)
2285 (struct charset_sort_data.priority): Now ptrdiff_t.
2286 (charset_compare): Don't overflow if priorities differ greatly.
2287 (Fsort_charsets): Don't assume list length fits in int.
2288 Check for size-calculation overflow when allocating sort data.
2289 (syms_of_charset): Allocate an initial charset table that is
2290 just under 64 KiB, to avoid problems with glibc malloc and mmap.
2291
2292 * cmds.c (internal_self_insert): Check for size-calculation overflow.
2293
2294 * composite.h (struct composition.glyph_len): Now int, not unsigned.
2295 The actual value is always <= INT_MAX, and leaving it unsigned made
2296 overflow checking harder.
2297
2298 * dispextern.h (struct glyph_matrix.rows_allocated)
2299 (struct face_cache.size): Now ptrdiff_t, for convenience in use
2300 with xpalloc. The values are still always <= INT_MAX.
2301
2302 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
2303
2304 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
2305 (SAFE_NALLOCA): New macro.
2306
2307 * region-cache.c (struct boundary.pos, find_cache_boundary)
2308 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
2309 (set_cache_region, invalidate_region_cache)
2310 (revalidate_region_cache, know_region_cache, region_cache_forward)
2311 (region_cache_backward, pp_cache):
2312 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
2313 so that ptrdiff_t * can be passed to xpalloc.
2314 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
2315 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
2316 (pp_cache): Don't assume cache_len fits in int.
2317 * region-cache.h: Adjust extern decls to match.
2318
2319 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
2320 EMACS_INT, since either will do, for xpalloc.
2321
2322 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
2323 (xnmalloc, xnrealloc, xpalloc): New functions.
2324
2325 * bidi.c (bidi_shelve_header_size): New constant.
2326 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
2327 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
2328
2329 * bidi.c (bidi_cache_shrink):
2330 * buffer.c (overlays_at, overlays_in, record_overlay_string)
2331 (overlay_strings):
2332 Don't update size of array until after memory allocation succeeds,
2333 because xmalloc/xrealloc may not return.
2334 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
2335 now that we have proper integer overflow checking.
2336 (record_overlay_string, overlay_strings): Catch overflows when
2337 calculating size of overlay_str_buf.
2338
2339 * callproc.c (Fcall_process): Check for size overflow when
2340 calculating size of args2.
2341 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
2342 Normally we prefer signed values, but sticking with ptrdiff_t would
2343 require adding more-complicated checks.
2344
2345 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
2346 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
2347 Redo buffer-overflow calculations to avoid integer overflow.
2348 Add a FIXME comment where memory seems to be over-allocated.
2349
2350 * character.c (Fstring): Check for size-calculation overflow.
2351
2352 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
2353 unnecessary integer overflow. Check for size overflow.
2354 (encode_coding_object): Don't update size until xmalloc succeeds.
2355
2356 * composite.c (get_composition_id): Check for overflow in glyph
2357 length calculations.
2358
2359 Integer and memory overflow fixes for display code.
2360 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
2361 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
2362 (scrolling_window): Check for overflow in size calculations.
2363 (line_draw_cost, realloc_glyph_pool, add_row_entry):
2364 Don't assume glyph table len fits in int.
2365 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
2366 (row_table_size): Now ptrdiff_t, not int.
2367 (scrolling_window): Avoid overflow in size calculations.
2368 Don't update size until allocation succeeds.
2369 * fns.c (concat): Check for overflow in size calculations.
2370 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
2371 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
2372 (NEXT_ALMOST_PRIME_LIMIT): New constant.
2373
2374 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
2375 (get_doc_string): Check for size calculation overflow.
2376 Don't update size until allocation succeeds.
2377 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
2378 EMACS_INT, where ptrdiff_t will do.
2379 (Fsubstitute_command_keys): Check for string overflow.
2380
2381 * editfns.c (set_time_zone_rule): Don't assume environment length
2382 fits in int.
2383 (message_length): Now ptrdiff_t, not int.
2384 (Fmessage_box): Don't update size until allocation succeeds.
2385 Don't assume message length fits in int.
2386 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
2387
2388 * emacs.c (main): Do not reallocate argv, since there is a null at
2389 the end that can be overwritten, and this way there's no need to
2390 worry about size-calculation overflow.
2391 (sort_args): Check for size-calculation overflow.
2392
2393 * eval.c (init_eval_once, grow_specpdl): Don't update size until
2394 alloc succeeds.
2395 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
2396
2397 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
2398 (x_set_scroll_bar_width, x_figure_window_size):
2399 Check for integer overflow.
2400 (x_set_alpha): Do not assume XINT fits in int.
2401
2402 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
2403 This is for the members text_lines, text_cols, total_lines, total_cols,
2404 where the system imposes an 'int' limit.
2405
2406 * fringe.c (Fdefine_fringe_bitmap):
2407 Don't update size until alloc works.
2408
2409 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
2410 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
2411
2412 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
2413 Check for size-calculation overflow.
2414 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
2415 do, as we prefer signed integers.
2416 (id_to_widget.max_size, id_to_widget.used)
2417 (xg_store_widget_in_map, xg_remove_widget_from_map)
2418 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
2419 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
2420 Use and return ptrdiff_t, not int.
2421 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
2422 * gtkutil.h: Change prototypes to match the above.
2423
2424 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
2425 are duplicate now that they've been promoted to lisp.h.
2426 (x_allocate_bitmap_record, x_alloc_image_color)
2427 (make_image_cache, cache_image, xpm_load):
2428 Don't update size until alloc is done.
2429 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
2430 (x_detect_edges):
2431 Check for size calculation overflow.
2432 (ct_colors_allocated_max): New constant.
2433 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
2434 overflow.
2435
2436 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
2437 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
2438 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
2439 Use ptrdiff_t, not int, to count maps.
2440 (read_char_minibuf_menu_prompt): Check for overflow in size
2441 calculations. Don't update size until allocation succeeds.
2442 Redo calculations to avoid overflow.
2443 * keyboard.h: Change prototypes to match the above.
2444
2445 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
2446 to count maps.
2447 (current_minor_maps): Check for size calculation overflow.
2448 * keymap.h: Change prototypes to match the above.
2449
2450 * lread.c (read1, init_obarray): Don't update size until alloc done.
2451
2452 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
2453 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
2454

2456 Now ptrdiff_t, not int.
2457 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
2458 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
2459

2464
2465 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
2466 overflow. Don't bother calling xmalloc when xrealloc will do.
2467
2468 * search.c (Freplace_match): Check for size calculation overflow.
2469 (Fset_match_data): Don't assume list lengths fit in 'int'.
2470
2471 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
2472 for command line length. Do not attempt to address one before the
2473 beginning of an array, as that's not portable.
2474
2475 * term.c (max_frame_lines): Remove; unused.
2476 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
2477 not int.
2478 (encode_terminal_code, calculate_costs): Check for size
2479 calculation overflow.
2480 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
2481 table lengths and related sizes. Don't update size until alloc
2482 done. Redo calculations to avoid overflow.
2483 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
2484
2485 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
2486 subtracting pointers.
2487 (gobble_line): Check for overflow more carefully. Don't update size
2488 until alloc done.
2489
2490 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
2491 Don't update size until alloc done.
2492 Redo size calculations to avoid overflow.
2493 Check for size calculation overflow.
2494 (main) [DEBUG]: Fix typo in invoking tparam1.
2495
2496 * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
2497 Use ptrdiff_t, not int, for sizes.

2500 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
2501 Use ptrdiff_t, not int, for sizes.
2502 (Finternal_make_lisp_face, cache_face):
2503 Check for size calculation overflow.
2504 (cache_face): Treat size calculation overflows as if they were
2505 memory exhaustion (the usual treatment), rather than aborting.
2506
2507 * xfns.c (x_encode_text, x_set_name_internal)
2508 (Fx_change_window_property): Use ptrdiff_t, not int, to count
2509 sizes, since they can exceed INT_MAX in size. Check for size
2510 calculation overflow.
2511
2512 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
2513 (xg_select): Check for size calculation overflow.
2514 Don't update size until alloc done.
2515
2516 * xrdb.c (get_environ_db): Don't assume path length fits in int,
2517 as sprintf is limited to int lengths.
2518
2519 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
2520 (X_LONG_MIN): New macros.
2521 Use them to make the following changes clearer.
2522 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
2523 This change doesn't affect the value now, but it may help remind
2524 future maintainers not to raise the value too much later.
2525 (SELECTION_QUANTUM): Remove, replacing with ...
2526 (selection_quantum): ... new function, which avoids overflow.
2527 All uses changed.
2528 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
2529 assumption that selection length fits in 'int'.
2530 (x_reply_selection_request, x_handle_selection_request)
2531 (x_get_window_property, receive_incremental_selection)
2532 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
2533 (lisp_data_to_selection_data, clean_local_selection_data):
2534 Use ptrdiff_t, not int, to record length of selection.
2535 (x_reply_selection_request, x_get_window_property)
2536 (receive_incremental_selection, x_property_data_to_lisp):
2537 Redo calculations to avoid overflow.
2538 (x_reply_selection_request): When sending hint, ceiling it at
2539 X_LONG_MAX rather than relying on wraparound overflow to send
2540 something.
2541 (x_get_window_property, receive_incremental_selection)
2542 (lisp_data_to_selection_data, x_property_data_to_lisp):
2543 Check for size-calculation overflow.
2544 (x_get_window_property, receive_incremental_selection)
2545 (lisp_data_to_selection_data, Fx_register_dnd_atom):
2546 Don't store size until memory allocation succeeds.
2547 (x_get_window_property): Plug memory leak on memory exhaustion.
2548 Don't double-block input; malloc is safe here. Don't assume 2**34
2549 - 4 fits in unsigned long. Add an xassert to check
2550 XGetWindowProperty overflow. Be more careful about overflow
2551 calculations, and distinguish size from memory overflow better.
2552 (receive_incremental_selection): When tracing, don't assume
2553 unsigned int is less than INT_MAX.
2554 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
2555 harmful) conversions of unsigned short to int.
2556 (lisp_data_to_selection_data): Don't assume that integers
2557 in the range -65535 through -1 fit in an X unsigned short.
2558 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
2559 result parameters unless successful. Rely on cons_to_unsigned
2560 to report problems with elements; the old code wasn't right anyway.
2561 (x_check_property_data): Check for int overflow; we cannot use
2562 a wider type due to X limits.
2563 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
2564
2565 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
2566
2567 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
2568 (x_term_init): Check for size calculation overflow.
2569 (x_color_cells): Don't store size until memory allocation succeeds.
2570 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
2571 Don't assume alloca size is less than MAX_ALLOCA.
2572 (x_term_init): Don't assume length fits in int (sprintf is limited
2573 to int size).
2574
2575 Use ptrdiff_t for composition IDs.

2595 * lisp.h (hash_lookup, hash_put):
2596 * minibuf.c (Ftest_completion):
2597 Use ptrdiff_t for hash table indexes, not int (which is too
2598 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
2599 32-bit --with-wide-int hosts).
2600
2601 * charset.c (Fdefine_charset_internal): Check for integer overflow.
2602 Add a FIXME comment about memory leaks.
2603 (syms_of_charset): Don't assume xmalloc returns.

2629
2630 * xterm.c: Don't go over XClientMessageEvent limit.
2631 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
2632 (x_send_scroll_bar_event): Likewise. Check that the size does not
2633 exceed limits imposed by XClientMessageEvent, as well as the usual
2634 ptrdiff_t and size_t limits.
2635
2636 * keyboard.c: Overflow, signedness and related fixes.
2637 (make_lispy_movement): Use same integer type in forward decl
2638 that is used in the definition.
2639 (read_key_sequence, keyremap_step):
2640 Change bufsize argument back to int, undoing my 2011-03-30 change.
2641 We prefer signed types, and int is wide enough here.
2642 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
2643 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
2644 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
2645 length, not size_t. Use ptrdiff_t for index, not int.
2646 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
2647 possibility of integer overflow.

2668 when the callers expect that.
2669 (image_ascent): Redo ascent calculation to avoid int overflow.
2670 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
2671 (lookup_image): Remove unnecessary tests.
2672 (xbm_image_p): Locals are now of int, not EMACS_INT,
2673 since parse_image_check makes sure they fit into int.
2674 (png_load, gif_load, svg_load_image):
2675 Prefer int to unsigned where either will do.
2676 (tiff_handler): New function, combining the cores of the
2677 old tiff_error_handler and tiff_warning_handler.
2678 This function is rewritten to use vsnprintf and thereby avoid
2679 stack buffer overflows. It uses only the features of vsnprintf
2680 that are common to both POSIX and native Microsoft.
2681 (tiff_error_handler, tiff_warning_handler): Use it.
2682 (tiff_load, gif_load, imagemagick_load_image):
2683 Don't assume :index value fits in 'int'.
2684 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

2686 the integer types that MagickCropImage accepts. Don't assume
2687 Vimagemagick_render_type has a nonnegative value. Don't assume

2698
2699 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
2700 the display spec is of the form `(space ...)'.
2701 (handle_display_spec): Return the value returned by
2702 handle_single_display_spec, not just 1 or zero.
2703 (handle_single_display_spec): If the display spec is of the form
2704 `(space ...)', and specifies display in the text area, return 2
2705 rather than 1.
2706 (try_cursor_movement): Check for the need to scroll more
2707 accurately, and prefer exact match for point under bidi.
2708 Don't advance `row' beyond the last row of the window.
2709
2710 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
2711 into disp_prop; all users changed.
2712

2726 buffers, return left-to-right.
2727 (set_cursor_from_row): Consider candidate row a win if its glyph
2728 represents a newline and point is on that newline. Fixes cursor
2729 positioning on the newline at EOL of R2L text within L2R
2730 paragraph, and vice versa.
2731 (try_cursor_movement): Check continued rows, in addition to
2732 continuation rows. Fixes unwarranted scroll when point enters a
2733 continued line of R2L text within an L2R paragraph, or vice versa.
2734 (cursor_row_p): Consider the case of point being equal to
2735 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
2736 from the end of a short line to the beginning of a continued line
2737 of R2L text within L2R paragraph.
2738 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
2739 composed characters.

2760
2761 * xdisp.c (redisplay_window): When computing centering_position,
2762 account for the height of the header line. (Bug#8874)
2763
2764 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
2765 instead of CHAR_TO_BYTE. Fixes a crash when a completion
2766 candidate is selected by the mouse, and that candidate has a
2767 composed character under the mouse.
2768
2769 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
2770 coordinates reported by pos-visible-in-window-p for a composed
2771 character in column zero.

2777 2011-08-22 Eli Zaretskii <eliz@gnu.org>
2778
2779 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
2780 consider it a hit if to_charpos is anywhere in the range of the
2781 composed buffer positions.
2782
2783 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
2784
2785 * image.c (gif_load): Don't assume that each subimage has the same
2786 dimensions as the base image. Handle disposal method that is
2787 "undefined" by the gif spec (Bug#9335).
2788
2789 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
2790

2795
2796 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
2797 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
2798 from an Org mode buffer to a Speedbar frame.
2799
2800 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
2801 a composition, take its buffer position from IT->cmp_it.charpos.
2802 Fixes cursor positioning at the beginning of a line that begins
2803 with a composed character.
2804
2805 2011-08-18 Eli Zaretskii <eliz@gnu.org>
2806
2807 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
2808 character bidirectional type, use STRONG_L instead. Fixes crashes
2809 in a buffer produced by `describe-categories'.
2810
2811 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
2812 members before the level stack, so they would be saved and
2813 restored when copying iterator state. Fixes incorrect reordering
2814 around TABs covered by display properties.
2815
2816 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
2817

2902 the event loop. Get status from as_status (Bug#7276).
2903
2904 * nsterm.m (sendEvent): If event is NSApplicationDefined and
2905 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
2906 the event loop (Bug#7276).

2941
2942 * xdisp.c (iterate_out_of_display_property): xassert that
2943 IT->position is set to within IT->object's boundaries. Break from
2944 the loop as soon as EOB is reached; avoids infloops in redisplay
2945 when IT->position is set up wrongly due to some bug.
2946 Set IT->current to match the bidi iterator unconditionally.
2947 (push_display_prop): Allow GET_FROM_STRING as IT->method on
2948 entry. Force push_it to save on the stack the current
2949 buffer/string position, to be restored by pop_it. Fix flags in
2950 the iterator structure wrt the object coming from a display
2951 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
2952 properties. (Bug#9284)
2953
2954 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
2955

2993 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
2994 display property strides EOL and includes a newline, as in
2995 longlines-mode. (Bug#9254)
2996 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
2997 word-wrap under bidirectional display. (Bug#9224)
2998
2999 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
3000 is non-zero, even if the data buffer is NULL. Fixes a crash in
3001 vertical-motion with longlines-mode. (Bug#9254)
3002
3003 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3004
3005 * bidi.c <bidi_cache_total_alloc>: Now static.
3006 (bidi_initialize): Initialize bidi_cache_total_alloc.
3007
3008 * xdisp.c (display_line): Release buffer allocated for shelved bidi
3009 cache. (Bug#9221)
3010
3011 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
3012 amount allocated this far in `bidi_cache_total_alloc'.
3013 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
3014 non-zero, only free the data buffer without restoring the cache
3015 contents. All callers changed.
3016
3017 * dispextern.h (bidi_unshelve_cache): Update prototype.
3018
3019 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
3020 (move_it_in_display_line, move_it_to)
3021 (move_it_vertically_backward, move_it_by_lines): Replace the call
3022 to xfree to an equivalent call to bidi_unshelve_cache.
3023 (move_it_in_display_line_to): Fix logic of returning
3024 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
3025
3026 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3027
3028 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
3029 came from a string character with a `cursor' property. (Bug#9229)
3030
3031 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3032
3033 * Makefile.in (LIB_PTHREAD): New variable.
3034 (LIBES): Add LIB_PTHREAD (Bug#9216).
3035
3036 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
3037 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
3038
3039 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
3040
3041 * regex.c (re_iswctype): Remove some redundant boolean conversions.
3042
3043 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3044
3045 * xterm.c (x_find_topmost_parent): New function.
3046 (x_set_frame_alpha): Find topmost parent window with
3047 x_find_topmost_parent and set the property there also (bug#9181).
3048 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
3049
3050 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
3051
3052 * callproc.c (Fcall_process): Avoid vfork clobbering
3053 the local vars buffer, coding_systems, current_dir.
3054
3055 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
3056
3057 * keymap.c (Fmake_composed_keymap): Move to subr.el.
3058
3059 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
3060
3061 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
3062 so that it is not optimized away.
3063
3064 * xdisp.c (compute_display_string_pos): Remove unused local.
3065
3066 2011-08-02 Eli Zaretskii <eliz@gnu.org>
3067
3068 Fix slow cursor motion and scrolling in large buffers with
3069 selective display, like Org Mode buffers. (Bug#9218)
3070
3071 * dispextern.h (struct bidi_it): New member disp_prop_p.
3072
3073 * xdisp.c: Remove one-slot cache of display string positions.
3074 (compute_display_string_pos): Accept an additional argument
3075 DISP_PROP_P; callers changed. Scan at most 5K characters forward
3076 for a display string or property. If found, set DISP_PROP_P
3077 non-zero.
3078
3079 * bidi.c (bidi_fetch_char): Accept an additional argument
3080 DISP_PROP_P, and pass it to compute_display_string_pos.
3081 Only handle text covered by a display string if DISP_PROP_P is returned
3082 non-zero. All callers of bidi_fetch_char changed.
3083
3084 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
3085
3086 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
3087
3088 2010-12-03 Don March <don@ohspite.net>
3089
3090 * keymap.c (Fdefine_key): Fix non-prefix key error message when
3091 last character M-[char] is translated to ESC [char] (bug#7541).
3092
3093 2011-08-02 Kenichi Handa <handa@m17n.org>
3094
3095 * lisp.h (uniprop_table): Extern it.
3096
3097 * chartab.c (uniprop_table): Make it non-static.
3098
3099 2011-08-01 Eli Zaretskii <eliz@gnu.org>
3100
3101 * xdisp.c (forward_to_next_line_start): Accept additional argument
3102 BIDI_IT_PREV, and store into it the state of the bidi iterator had
3103 on the newline.
3104 (reseat_at_next_visible_line_start): Use the bidi iterator state
3105 returned by forward_to_next_line_start to restore the state of
3106 it->bidi_it after backing up to previous newline. (Bug#9212)
3107
3108 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
3109
3110 * regex.c (re_comp): Protoize.
3111 (re_exec): Fix return type.
3112 (regexec): Fix type of `ret'. (Bug#9203)
3113
3114 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3115
3116 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
3117 This is needed if max-image-size is a floating-point number.
3118
3119 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3120
3121 * print.c (print_object): Print empty symbol as ##.
3122
3123 * lread.c (read1): Read ## as empty symbol.
3124
3125 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3126
3127 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
3128 setting frame foreground color (Bug#9175).
3129 (x_set_background_color): Likewise.
3130
3131 * nsmenu.m (-setText): Size tooltip dimensions precisely to
3132 contents (Bug#9176).
3133 (EmacsTooltip -init): Remove bezels and add shadows to
3134 tooltip windows.
3135
3136 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
3137 or scroll bar (Bug#8470).
3138
3139 * nsfont.m (nsfont_open): Remove assignment to voffset and
3140 unnecessary vars hshink, expand, hd, full_height, min_height.
3141 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
3142
3143 * nsterm.h (nsfont_info): Remove voffset field.
3144
3145 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3146
3147 Implement strike-through and overline on NextStep (Bug#8863).
3148
3149 * nsfont.m (nsfont_open): Use underline position provided by font,
3150 instead of hard-coded value of 2.
3151 (nsfont_draw): Call ns_draw_text_decoration instead.
3152
3153 * nsterm.h: Add declaration for ns_draw_text_decoration.
3154
3155 * nsterm.m (ns_draw_text_decoration): New function for drawing
3156 underline, overline, and strike-through.
3157 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
3158 ns_draw_text_decoration. Change treatment of cursor drawing to
3159 accommodate underlining, etc.
3160
3161 2011-07-28 Eli Zaretskii <eliz@gnu.org>
3162
3163 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
3164 default.
3165
3166 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3167
3168 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
3169 Without this fix, if a signal arrives just after memory fills up,
3170 'malloc' might be invoked reentrantly.
3171
3172 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
3173 In other words, assume that every image size is allowed, on non-X
3174 hosts. This assumption is probably wrong, but it lets Emacs compile.
3175
3176 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3177
3178 * regex.c (re_iswctype): Convert return values to boolean.
3179
3180 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
3181
3182 * xdisp.c (compute_display_string_pos): Don't use cached display
3183 string position if the buffer had its restriction changed.
3184 (Bug#9184)
3185
3186 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3187
3188 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3189
3190 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3191
3192 Integer signedness and overflow and related fixes. (Bug#9079)
3193
3194 * bidi.c: Integer size and overflow fixes.
3195 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
3196 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
3197 (bidi_cache_find_level_change, bidi_cache_ensure_space)
3198 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
3199 (bidi_find_other_level_edge):
3200 Use ptrdiff_t instead of EMACS_INT where either will do.
3201 This works better on 32-bit hosts configured --with-wide-int.
3202 (bidi_cache_ensure_space): Check for size-calculation overflow.
3203 Use % rather than repeated addition, for better worst-case speed.
3204 Don't set bidi_cache_size until after xrealloc returns, because it
3205 might not return.
3206 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
3207 (bidi_cache_ensure_space): Also check that the bidi cache size
3208 does not exceed that of the largest Lisp string or buffer. See Eli
3209 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
3210
3211 * alloc.c (__malloc_size_t): Remove.
3212 All uses replaced by size_t. See Andreas Schwab's note
3213 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
3214
3215 * image.c: Improve checking for integer overflow.
3216 (check_image_size): Assume that f is nonnull, since
3217 it is always nonnull in practice. This is one less thing to
3218 worry about when checking for integer overflow later.
3219 (x_check_image_size): New function, which checks for integer
3220 overflow issues inside X.
3221 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
3222 This removes the need for a memory_full check.
3223 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
3224 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
3225 (xbm_read_bitmap_data): Change locals back to 'int', since
3226 their values must fit in 'int'.
3227 (xpm_load_image, png_load, tiff_load):
3228 Invoke x_create_x_image_and_pixmap earlier,
3229 to avoid much needless work if the image is too large.
3230 (tiff_load): Treat overly large images as if
3231 x_create_x_image_and_pixmap failed, not as malloc failures.
3232 (gs_load): Use x_check_image_size.
3233
3234 * gtkutil.c: Omit integer casts.
3235 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
3236 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
3237
3238 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
3239
3240 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
3241 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
3242 would wrongly return t on a 64-bit host.
3243
3244 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
3245 The plain *_OVERFLOW macros run afoul of GCC bug 49705
3246 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
3247 and therefore cause GCC to emit a bogus diagnostic in some cases.
3248
3249 * image.c: Integer signedness and overflow and related fixes.
3250 This is not an exhaustive set of fixes, but it's time to
3251 record what I've got.
3252 (lookup_pixel_color, check_image_size): Remove redundant decls.
3253 (check_image_size): Don't assume that arbitrary EMACS_INT values
3254 fit in 'int', or that arbitrary 'double' values fit in 'int'.
3255 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
3256 (tiff_load, imagemagick_load_image):
3257 Check for overflow in size calculations.
3258 (x_create_x_image_and_pixmap): Remove unnecessary test for
3259 xmalloc returning NULL; that can't happen.
3260 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
3261 (xpm_color_bucket): Use better integer hashing function.
3262 (xpm_cache_color): Don't possibly over-allocate memory.
3263 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
3264 (gif_memory_source):
3265 Use ptrdiff_t, not int or size_t, to record sizes.
3266 (png_load): Don't assume values greater than 2**31 fit in 'int'.
3267 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
3268 either works, as we prefer signed integers.
3269 (tiff_read_from_memory, tiff_write_from_memory):
3270 Return tsize_t, not size_t, since that's what the TIFF API wants.
3271 (tiff_read_from_memory): Don't fail simply because the read would
3272 go past EOF; instead, return a short read.
3273 (tiff_load): Omit no-longer-needed casts.
3274 (Fimagemagick_types): Don't assume size fits into 'int'.
3275
3276 Improve hashing quality when configured --with-wide-int.
3277 * fns.c (hash_string): New function, taken from sxhash_string.
3278 Do not discard information about ASCII character case; this
3279 discarding is no longer needed.
3280 (sxhash-string): Use it. Change sig to match it. Caller changed.
3281 * lisp.h: Declare it.
3282 * lread.c (hash_string): Remove, since we now use fns.c's version.
3283 The fns.c version returns a wider integer if --with-wide-int is
3284 specified, so this should help the quality of the hashing a bit.
3285
3286 * emacs.c: Integer overflow minor fix.
3287 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
3288 Define only if GNU_LINUX.
3289 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
3290
3291 * dispnew.c: Integer signedness and overflow fixes.
3292 Remove unnecessary forward decls, that were a maintenance hassle.
3293 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
3294 All uses changed.
3295 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
3296 (scrolling_window): Use ptrdiff_t, not int, for byte count.
3297 (prepare_desired_row, line_draw_cost):
3298 Use int, not unsigned, where either works.
3299 (save_current_matrix, restore_current_matrix):
3300 Use ptrdiff_t, not size_t, where either works.
3301 (init_display): Check for overflow more accurately, and without
3302 relying on undefined behavior.
3303
3304 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
3305 Remove, replacing with the new symbols in lisp.h. All uses changed.
3306 * fileio.c (make_temp_name):
3307 * filelock.c (lock_file_1, lock_file):
3308 * xdisp.c (message_dolog):
3309 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
3310 Use pMd etc. instead.
3311 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
3312 replacing the pWIDE etc. symbols removed from editfns.c.
3313
3314 * keyboard.h (num_input_events): Now uintmax_t.
3315 This is (very slightly) less likely to mess up due to wraparound.
3316 All uses changed.
3317
3318 * buffer.c: Integer signedness fixes.
3319 (alloc_buffer_text, enlarge_buffer_text):
3320 Use ptrdiff_t rather than size_t when either will do, as we prefer
3321 signed integers.
3322
3323 * alloc.c: Integer signedness and overflow fixes.
3324 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
3325 (__malloc_size_t): Default to size_t, not to int.
3326 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
3327 (Fgarbage_collect, mark_object_loop_halt, mark_object):
3328 Prefer ptrdiff_t to size_t when either would do, as we prefer
3329 signed integers.
3330 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
3331 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
3332 Now const. Initialize with values that are in range even if char
3333 is signed.
3334 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
3335 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
3336 These functions do the right thing with sizes > 2**32.
3337 (check_depth): Now ptrdiff_t, not int.
3338 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
3339 Adjust to new way of storing sizes. Check for size overflow bugs
3340 in rest of code.
3341 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
3342 slightly wrong anyway, as it missed one instance of
3343 XMALLOC_OVERRUN_CHECK_OVERHEAD.
3344 (refill_memory_reserve): Omit needless cast to size_t.
3345 (mark_object_loop_halt): Mark as externally visible.
3346
3347 * xselect.c: Integer signedness and overflow fixes.
3348 (Fx_register_dnd_atom, x_handle_dnd_message):
3349 Use ptrdiff_t, not size_t, since we prefer signed.
3350 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
3351 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
3352 x_dnd_atoms_size and x_dnd_atoms_length.
3353
3354 * doprnt.c: Prefer signed to unsigned when either works.
3355 * eval.c (verror):
3356 * doprnt.c (doprnt):
3357 * lisp.h (doprnt):
3358 * xdisp.c (vmessage):
3359 Use ptrdiff_t, not size_t, when using or implementing doprnt,
3360 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
3361 prefer signed arithmetic to avoid comparison confusion.
3362 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
3363 but is a bit tricky.
3364
3365 Assume freestanding C89 headers, string.h, stdlib.h.
3366 * data.c, doprnt.c, floatfns.c, print.c:
3367 Include float.h unconditionally.
3368 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
3369 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
3370 * regex.c: Likewise for stddef.h, string.h.
3371 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
3372 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
3373 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
3374 (STDC_HEADERS): Remove obsolete defines.
3375 * sysdep.c: Include limits.h unconditionally.
3376
3377 Assume support for memcmp, memcpy, memmove, memset.
3378 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
3379 * regex.c (memcmp, memcpy):
3380 Remove; we assume C89 now.
3381
3382 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
3383 (__malloc_safe_bcopy): Remove; no longer needed.
3384
3385 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
3386 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
3387 well either way, and we prefer signed to unsigned.
3388
3389 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
3390
3391 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
3392 closes the connection while we're reading (bug#9182).
3393
3394 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
3395
3396 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
3397 are specified (Bug#9168).
3398
3399 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
3400
3401 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
3402 Found by GCC static checking and --with-wide-int on a 32-bit host.
3403
3404 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3405
3406 * xdisp.c (compute_display_string_pos): Fix logic of caching
3407 previous display string position. Initialize cached_prev_pos to
3408 -1. Fixes slow-down at the beginning of a buffer.
3409
3410 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3411
3412 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3413 for attrs[LFACE_FONTSET_INDEX].
3414

3416
3417 * xml.c (parse_region): Remove unused local
3418 that was recently introduced.
3419
3420 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3421
3422 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3423 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3424
3425 * xdisp.c (move_it_in_display_line_to): Record the best matching
3426 position for TO_CHARPOS while scanning the line, and restore it on
3427 exit if none of the characters scanned was an exact match.
3428 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3429 when exact match is impossible due to invisible text, and the
3430 lines are truncated.
3431
3432 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3433
3434 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3435 for OSX >= 10.7.
3436
3437 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3438
3439 Fix a significant slow-down of cursor motion with C-n, C-p,
3440 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3441 auto-repeat under bidi redisplay in fontified buffers.
3442 * xdisp.c (compute_stop_pos_backwards): New function.
3443 (next_element_from_buffer): Call compute_stop_pos_backwards to
3444 find a suitable prev_stop when we find ourselves before
3445 base_level_stop.
3446 (reseat): Don't look for prev_stop, as that could mean a very long
3447 run.
3448 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3449 <cached_disp_overlay_modiff>: Cache for last found display string
3450 position.
3451 (compute_display_string_pos): Return the cached position if asked
3452 about the same buffer in the same area of character positions, and
3453 the buffer wasn't changed since the time the display string
3454 position was cached.
3455
3456 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3457
3458 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3459 is an integer, which is important for empty lines. (Bug#9149)
3460
3461 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3462
3463 * frame.c (Fmodify_frame_parameters): In tty case, update the
3464 default face if necessary (Bug#4238).
3465
3466 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
3467
3468 * editfns.c (Fstring_to_char): No need to explain what a character
3469 is in the docstring (Bug#6576).
3470
3471 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3472
3473 * xml.c (parse_region): Make sure we always return a tree.
3474
3475 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
3476
3477 * xml.c (parse_region): If a document contains only comments,
3478 return that, too.
3479
3480 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3481
3482 * xml.c (make_dom): Return comments, too.
3483
3484 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
3485
3486 Port to OpenBSD.
3487 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
3488 and the surrounding thread.
3489 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
3490 rather than fgets, and retry after EINTR. Otherwise, 'emacs
3491 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
3492 timer goes off.
3493 * s/openbsd.h (BROKEN_SIGIO): Define.
3494 * unexelf.c (unexec) [__OpenBSD__]:
3495 Don't update the .mdebug section of the Alpha COFF symbol table.
3496
3497 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3498
3499 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
3500 (bug#8460).
3501
3502 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
3503
3504 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
3505 This fixes some race conditions on the permissions of any newly
3506 created file.
3507
3508 * alloc.c (valid_pointer_p): Use pipe, not open.
3509 This fixes some permissions issues when debugging.
3510
3511 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
3512 If fchown fails to set both uid and gid, try to set just gid,
3513 as that is sometimes allowed. Adjust the file's mode to eliminate
3514 setuid or setgid bits that are inappropriate if fchown fails.
3515
3516 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3517
3518 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
3519 to compare Lisp_Objects.
3520 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
3521 global_gnutls_log_level, don't mistake it for a Lisp_Object.
3522 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
3523
3524 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
3525
3526 * lread.c (read_integer): Unread even EOF character.
3527 (read1): Likewise. Properly record start position of symbol.
3528
3529 * lread.c (read1): Read `#:' as empty uninterned symbol if no
3530 symbol character follows.
3531
3532 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
3533
3534 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
3535 This works around a problem with the previous change to Fcopy_file.
3536 Recent glibc declares fchown with __attribute__((warn_unused_result)),
3537 and without this change, GCC might complain about discarding
3538 fchown's return value.
3539
3540 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
3541
3542 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
3543
3544 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
3545
3546 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
3547
3548 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
3549
3550 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
3551 it's used from the C level.
3552
3553 * process.c: Use the same condition for POLL_FOR_INPUT in both
3554 keyboard.c and process.c (bug#1858).
3555
3556 2011-07-09 Lawrence Mitchell <wence@gmx.li>
3557
3558 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
3559 (Fgnutls_boot): Use it.
3560
3561 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
3562
3563 * doc.c (Fsubstitute_command_keys): Revert last change.
3564
3565 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
3566
3567 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
3568 quotes the next character, and doesn't affect other longer
3569 sequences (bug#8935).
3570
3571 * lread.c (syms_of_lread): Clarify that is isn't only
3572 `eval-buffer' and `eval-defun' that's affected by
3573 `lexical-binding' (bug#8460).
3574
3575 2011-07-15 Eli Zaretskii <eliz@gnu.org>
3576
3577 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
3578 bidi redisplay when a line includes both an image and is truncated.
3579
3580 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
3581
3582 Fix minor problems found by static checking.
3583 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
3584 (elsz): Now a signed constant, not a size_t var. We prefer signed
3585 types to unsigned, to avoid integer comparison confusion. Without
3586 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
3587 "cannot optimize loop, the loop counter may overflow", a symptom
3588 of the confusion.
3589 * indent.c (Fvertical_motion): Mark locals as initialized.
3590 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
3591
3592 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
3593
3594 * search.c (Fre_search_backward): Mention `case-fold-search' in
3595 all the re_search_* functions (bug#8138).
3596
3597 * keyboard.c (Fopen_dribble_file): Document when the file is
3598 closed (bug#8056).

3602 * bidi.c (bidi_dump_cached_states): Fix format of displaying
3603 bidi_cache_idx.
3604
3605 Support bidi reordering of display and overlay strings.
3606 * xdisp.c (compute_display_string_pos)
3607 (compute_display_string_end): Accept additional argument STRING.
3608 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.

3612 NULL (avoids a crash in bidi_paragraph_init).
3613 Initialize itb.string.lstring.
3614 (init_iterator): Call bidi_init_it only of a valid
3615 buffer position was specified. Initialize paragraph_embedding to
3616 L2R.
3617 (reseat_to_string): Initialize the bidi iterator.
3618 (display_string): If we need to ignore text properties of
3619 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
3620 original value of -1 will not work with bidi.)
3621 (compute_display_string_pos): First arg is now struct
3622 `text_pos *'; all callers changed. Support display properties on
3623 Lisp strings.
3624 (compute_display_string_end): Support display properties on Lisp
3625 strings.
3626 (init_iterator, reseat_1, reseat_to_string): Initialize the
3627 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
3628 when iterating on a string not from display properties).
3629 (compute_display_string_pos, compute_display_string_end):
3630 Fix calculation of the object to scan. Fixes an error when using
3631 arrow keys.
3632 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
3633 base_level_stop; instead, set base_level_stop to BEGV.
3634 Fixes crashes in vertical-motion.
3635 (next_element_from_buffer): Improve commentary for when
3636 the iterator is before prev_stop.
3637 (init_iterator): Initialize bidi_p from the default value of
3638 bidi-display-reordering, not from buffer-local value. Use the
3639 buffer-local value only if initializing for buffer iteration.
3640 (handle_invisible_prop): Support invisible properties on strings
3641 that are being bidi-reordered.
3642 (set_iterator_to_next): Support bidi reordering of C strings and
3643 Lisp strings.

3647 (display_string): Support display of R2L glyph rows.
3648 Use IT_STRING_CHARPOS when displaying from a Lisp string.
3649 (init_iterator): Don't initialize it->bidi_p for strings
3650 here.
3651 (reseat_to_string): Initialize it->bidi_p for strings here.
3652 (next_element_from_string, next_element_from_c_string)

3655 structure.
3656 (face_before_or_after_it_pos): Support bidi iteration.
3657 (next_element_from_c_string): Handle the case of the first string
3658 character that is not the first one in the visual order.
3659 (get_visually_first_element): New function, refactored from common
3660 parts of next_element_from_buffer, next_element_from_string, and
3661 next_element_from_c_string.
3662 (tool_bar_lines_needed, redisplay_tool_bar)
3663 (display_menu_bar): Force left-to-right direction. Add a FIXME
3664 comment for making that be controlled by a user option.
3665 (push_it, pop_it): Save and restore the state of the
3666 bidi iterator. Save and restore the bidi_p flag.
3667 (pop_it): Iterate out of display property for string iteration as
3668 well.
3669 (iterate_out_of_display_property): Support iteration over strings.
3670 (handle_single_display_spec): Set up it->bidi_it for iteration
3671 over a display string, and call bidi_init_it.

3673 (get_overlay_strings_1, push_display_prop): Set up the bidi
3674 iterator for displaying display or overlay strings.
3675 (forward_to_next_line_start): Don't use the shortcut if
3676 bidi-iterating.
3677 (back_to_previous_visible_line_start): If handle_display_prop
3678 pushed the iterator stack, restore the internal state of the bidi
3679 iterator by calling bidi_pop_it same number of times.
3680 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
3681 and we are bidi-iterating, don't decrement the iterator position;
3682 instead, set the first_elt flag in the bidi iterator, to produce
3683 the same effect.
3684 (reseat_1): Remove redundant setting of string_from_display_prop_p.
3685 (push_display_prop): xassert that we are iterating a buffer.
3686 (push_it, pop_it): Save and restore paragraph_embedding member.
3687 (handle_single_display_spec, next_overlay_string)
3688 (get_overlay_strings_1, reseat_1, reseat_to_string)

3697 (pop_it): Call iterate_out_of_display_property only if we are
3698 popping after iteration over a string that came from a display
3699 property. Fix a typo in popping stretch info. Add an assertion
3700 for verifying that the iterator position is in sync with the bidi
3701 iterator.
3702 (handle_single_display_spec, get_overlay_strings_1)
3703 (push_display_prop): Fix initialization of paragraph direction for
3704 string when that of the parent object is not yet determined.
3705 (reseat_1): Call bidi_init_it to resync the bidi
3706 iterator with IT's position. (Bug#7616)
3707 (find_row_edges): If ROW->start.pos gives position
3708 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
3709 (handle_stop, back_to_previous_visible_line_start, reseat_1):
3710 Reset the from_disp_prop_p flag.
3711 (SAVE_IT, RESTORE_IT): New macros.

3716 (try_scrolling, redisplay_window, display_line): Use them when
3717 saving a temporary copy of the iterator and restoring it back.
3718 (back_to_previous_visible_line_start, reseat_1)
3719 (init_iterator): Empty the bidi cache "stack".
3720 (move_it_in_display_line_to): If iterator ended up at
3721 EOL, but we never saw any buffer positions smaller than
3722 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
3723 motion in bidi-reordered lines.
3724 (move_it_in_display_line_to): Record prev_method and prev_pos
3725 immediately before the call to set_iterator_to_next. Fixes cursor
3726 motion in bidi-reordered lines with stretch glyphs and strings
3727 displayed in margins. (Bug#8133) (Bug#8867)
3728 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
3729 TO_CHARPOS.
3730 (pos_visible_p): Support positions in bidi-reordered lines.
3731 Save and restore bidi cache.
3732
3733 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

3743 (bidi_move_to_visually_next): Compare cache index with
3744 bidi_cache_start rather than with zero.
3745 (bidi_fetch_char): Accept new argument STRING; all callers
3746 changed. Support iteration over a string. Support strings with
3747 display properties. Support unibyte strings. Fix the type of
3748 `len' according to what STRING_CHAR_AND_LENGTH expects.
3749 (bidi_paragraph_init, bidi_resolve_explicit_1)
3750 (bidi_resolve_explicit, bidi_resolve_weak)
3751 (bidi_level_of_next_char, bidi_move_to_visually_next):

3769 (bidi_initialize): Initialize the bidi cache start stack pointer.
3770 (bidi_cache_ensure_space): New function, refactored from part of

3785
3786 * dispextern.h (struct bidi_string_data): New structure.
3787 (struct bidi_it): New member `string'. Make flag members be 1-bit
3788 fields, and put them last in the struct.
3789 (compute_display_string_pos, compute_display_string_end):
3790 Update prototypes.
3791 (bidi_push_it, bidi_pop_it): Add prototypes.
3792 (struct iterator_stack_entry): New members bidi_p,
3793 paragraph_embedding, and from_disp_prop_p.

3844 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
3845
3846 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
3847 The old code sometimes used this field without initializing it.
3848
3849 * alloc.c (gc_sweep): Don't read past end of array.
3850 In theory, the old code could also have corrupted Emacs internals,
3851 though it'd be very unlikely.
3852
3853 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
3854
3855 * character.c (Fcharacterp): Don't advertise optional ignored

3951
3952 2011-07-08 Paul Eggert <eggert@cs.ucla.edu>
3953
3954 Use pthread_sigmask, not sigprocmask (Bug#9010).
3955 sigprocmask is portable only for single-threaded applications, and
3956 Emacs can be multi-threaded when it uses GTK.

4114 (clone_per_buffer_values): Don't assume that

4154
4155 Random fixes. E.g., (random) never returned negative values.
4156 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
4157 subseconds part to the entropy, as that's a bit more random.
4158 Prefer signed to unsigned, since the signedness doesn't matter and
4159 in general we prefer signed. When given a limit, use a
4160 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
4161 latter isn't right if USE_2_TAGS_FOR_INTS.
4162 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
4163 not 0..VALMASK. Don't discard "excess" bits that random () returns.

4173 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
4174
4175 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
4176 This is more efficient than Ffile_directory_p and avoids a minor race.
4177
4178 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
4179
4180 * buffer.c (Foverlay_put): Say what the return value is

4187 error be more correct.

4201 (syms_of_gnutls): Remove duplicate DEFSYM for
4202 Qgnutls_bootprop_verify_hostname_error, an error for
4203 Qgnutls_bootprop_verify_error (which is no longer used).
4204
4205 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
4206 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
4207 Also (re)move comments that are misplaced or no longer relevant.

4308 * eval.c (struct backtrace): Simplify and port the data structure.
4309 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a

4397
4398 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling

4502 to improve quality of diagnostics for out-of-range radices.
4503 Calculate buffer size correctly for out-of-range radices.
4504 (read1): Check for integer overflow in radices, and in
4505 read-circle numbers.
4506 (read_escape): Avoid int overflow.
4507 (Fload, openp, read_buffer_size, read1)
4508 (substitute_object_recurse, read_vector, read_list, map_obarray):

4531 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
4532 The following patches are for when GLYPH_DEBUG && !XASSERT.
4533 * dispextern.h (trace_redisplay_p, dump_glyph_string):
4534 * dispnew.c (flush_stdout):
4535 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
4536 Mark as externally visible.
4537 * dispnew.c (check_window_matrix_pointers): Now static.

4547 Now static.
4548 (debug_method_add): Use va_list and vsprintf rather than relying
4549 on undefined behavior with wrong number of arguments.
4550 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
4551 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
4552 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
4553 since we're not interested in debugging glyphs with old libraries.
4554 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
4555 GCC 4.6.0's static checking.
4556
4557 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

4617 Detect integer overflow in repeat count.
4618 (message_dolog): Don't assume print length fits in 39 bytes.
4619 (display_mode_element): Don't assume strlen fits in int.

4640 * filelock.c: Fix some buffer overrun and integer overflow issues.
4641 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
4642 Reformulate so as not to need the command string.
4643 Invoke gzip -cd rather than gunzip, as it's more portable.
4644 (lock_info_type, lock_file_1, lock_file):
4645 Don't assume pid_t and time_t fit in unsigned long.
4646 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
4647 (current_lock_owner): Prefer signed type for sizes.
4648 Use memcpy, not strncpy, where memcpy is what is really wanted.
4649 Don't assume (via atoi) that time_t and pid_t fit in int.
4650 Check for time_t and/or pid_t out of range, e.g., via a network share.
4651 Don't alloca where an auto var works fine.
4652
4653 * fileio.c: Fix some integer overflow issues.
4654 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
4655 Don't assume string length fits in int.
4656 (directory_file_name): Don't assume string length fits in long.
4657 (make_temp_name): Don't assume pid fits in int, or that its print
4658 length is less than 20.
4659
4660 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
4661
4662 * coding.c (make_subsidiaries): Don't assume string length fits in int.
4663
4664 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
4665
4666 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
4667 We prefer signed integers, even for size calculations.
4668
4669 * emacs.c: Don't assume string length fits in 'int'.
4670 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
4671 (main): Don't invoke strlen when not needed.
4672
4673 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
4674 (XD_DEBUG_MESSAGE): Don't waste a byte.
4675
4676 * callproc.c (getenv_internal_1, getenv_internal)
4677 (Fgetenv_internal):
4678 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
4679
4680 * lread.c (invalid_syntax): Omit length argument.
4681 All uses changed. This doesn't fix a bug, but it simplifies the
4682 code away from its former Hollerith-constant appearance, and it's
4683 one less 'int' to worry about when looking at integer-overflow issues.
4684 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
4685
4686 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4687 This didn't break anything, but it didn't help either.
4688 It's confusing to put a bogus integer in a place where the actual
4689 value does not matter.
4690 (LIST_END_P): Remove unused macro and its bogus comment.
4691 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
4692
4693 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
4694 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
4695 implementation.
4696 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
4697 We prefer signed types, and the value cannot exceed the EMACS_INT
4698 range anyway (because otherwise the length would not be representable).
4699 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
4700 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
4701 This avoids a GCC warning when WIDE_EMACS_INT.
4702
4703 * indent.c (sane_tab_width): New function.
4704 (current_column, scan_for_column, Findent_to, position_indentation)
4705 (compute_motion): Use it. This is just for clarity.
4706 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
4707
4708 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
4709
4710 * lisp.h (lint_assume): New macro.
4711 * composite.c (composition_gstring_put_cache):
4712 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
4713
4714 * editfns.c, insdel.c:
4715 Omit unnecessary forward decls, to simplify future changes.
4716
4717 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
4718
4719 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
4720
4721 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4722 Use much-faster test for byte-length change.
4723 Don't assume string byte-length fits in 'int'.
4724 Check that character arg fits in 'int'.
4725 (mapcar1): Declare byte as byte, for clarity.
4726
4727 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
4728
4729 * fns.c (concat): Catch string overflow earlier.
4730 Do not rely on integer wraparound.
4731
4732 * dispextern.h (struct it.overlay_strings_charpos)
4733 (struct it.selective): Now EMACS_INT, not int.
4734 * xdisp.c (forward_to_next_line_start)
4735 (back_to_previous_visible_line_start)
4736 (reseat_at_next_visible_line_start, next_element_from_buffer):
4737 Don't arbitrarily truncate the value of 'selective' to int.
4738
4739 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
4740
4741 * composite.c: Don't truncate sizes to 'int'.
4742 (composition_gstring_p, composition_reseat_it)
4743 (composition_adjust_point): Use EMACS_INT, not int.
4744 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
4745 not EMACS_UINT, for indexes.
4746
4747 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
4748
4749 * buffer.c: Include <verify.h>.
4750 (struct sortvec.priority, struct sortstr.priority):
4751 Now EMACS_INT, not int.
4752 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
4753 (struct sortstr.size, record_overlay_string)
4754 (struct sortstrlist.size, struct sortlist.used):
4755 Don't truncate size to int.
4756 (record_overlay_string): Check for size-calculation overflow.
4757 (init_buffer_once): Check at compile-time, not run-time.
4758
4759 2011-06-22 Jim Meyering <meyering@redhat.com>
4760
4761 Don't leak an XBM-image-sized buffer
4762 * image.c (xbm_load): Free the image buffer after using it.
4763
4764 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
4765
4766 Port to Sun C.
4767 * composite.c (find_automatic_composition): Omit needless 'return 0;'
4768 that Sun C diagnosed.
4769 * fns.c (secure_hash): Fix pointer signedness issue.
4770 * intervals.c (static_offset_intervals): New function.
4771 (offset_intervals): Use it.
4772
4773 2011-06-21 Leo Liu <sdl.web@gmail.com>
4774
4775 * deps.mk (fns.o):
4776 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
4777 sha512.h.
4778
4779 * fns.c (secure_hash): Rename from crypto_hash_function and change
4780 the first arg to accept symbols.
4781 (Fsecure_hash): New primitive.
4782 (syms_of_fns): New symbols.
4783
4784 2011-06-20 Deniz Dogan <deniz@dogan.se>
4785
4786 * process.c (Fset_process_buffer): Clarify return value in
4787 docstring.
4788
4789 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
4790
4791 * dispnew.c (add_window_display_history): Use BVAR.
4792
4793 * xdisp.c (debug_method_add): Use BVAR.
4794 (check_window_end, dump_glyph_matrix, dump_glyph)
4795 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
4796
4797 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
4798 Likewise.
4799
4800 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
4801 check till after the cache is created in init_frame_faces.
4802
4803 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
4804
4805 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
4806
4807 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
4808
4809 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
4810 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
4811 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
4812
4813 Improve buffer-overflow checking (Bug#8873).
4814 * fileio.c (Finsert_file_contents):
4815 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
4816 Remove the old (too-loose) buffer overflow checks.
4817 They weren't needed, since make_gap checks for buffer overflow.
4818 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
4819 The old code merely checked for Emacs fixnum overflow, and relied
4820 on undefined (wraparound) behavior. The new code avoids undefined
4821 behavior, and also checks for ptrdiff_t and/or size_t overflow.
4822
4823 * editfns.c (Finsert_char): Don't dump core with very negative counts.
4824 Tune. Don't use wider integers than needed. Don't use alloca.
4825 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
4826
4827 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
4828
4829 * insdel.c, lisp.h (buffer_overflow): New function.
4830 (insert_from_buffer_1, replace_range, replace_range_2):
4831 * insdel.c (make_gap_larger):
4832 * editfns.c (Finsert_char):
4833 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
4834
4835 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
4836
4837 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
4838
4839 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
4840
4841 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
4842 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
4843
4844 * fileio.c: Don't assume EMACS_INT fits in off_t.
4845 (emacs_lseek): New static function.
4846 (Finsert_file_contents, Fwrite_region): Use it.
4847 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
4848
4849 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
4850
4851 * fns.c: Don't overflow int when computing a list length.
4852 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
4853 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
4854 truncation on 64-bit hosts. Check for QUIT every
4855 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
4856 faster and is responsive enough.
4857 (Flength): Report an error instead of overflowing an integer.
4858 (Fsafe_length): Return a float if the value is not representable
4859 as a fixnum. This shouldn't happen except in contrived situations.
4860 (Fnthcdr, Fsort): Don't assume list length fits in int.
4861 (Fcopy_sequence): Don't assume vector length fits in int.
4862
4863 * alloc.c: Check that resized vectors' lengths fit in fixnums.
4864 (header_size, word_size): New constants.
4865 (allocate_vectorlike): Don't check size overflow here.
4866 (allocate_vector): Check it here instead, since this is the only
4867 caller of allocate_vectorlike that could cause overflow.
4868 Check that the new vector's length is representable as a fixnum.
4869
4870 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
4871 The previous code was bogus. For example, next_almost_prime (32)
4872 returned 39, which is undesirable as it is a multiple of 3; and
4873 next_almost_prime (24) returned 25, which is a multiple of 5 so
4874 why was the code bothering to check for multiples of 7?
4875
4876 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
4877
4878 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
4879
4880 Variadic C functions now count arguments with ptrdiff_t.
4881 This partly undoes my 2011-03-30 change, which replaced int with size_t.
4882 Back then I didn't know that the Emacs coding style prefers signed int.
4883 Also, in the meantime I found a few more instances where arguments
4884 were being counted with int, which may truncate counts on 64-bit
4885 machines, or EMACS_INT, which may be unnecessarily wide.
4886 * lisp.h (struct Lisp_Subr.function.aMANY)
4887 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
4888 Arg counts are now ptrdiff_t, not size_t.
4889 All variadic functions and their callers changed accordingly.
4890 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
4891 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
4892 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
4893 * callint.c (Fcall_interactively): Check arg count for overflow,
4894 to avoid potential buffer overrun. Use signed char, not 'int',
4895 for 'varies' array, so that we needn't bother to check its size
4896 calculation for overflow.
4897 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
4898 * eval.c (apply_lambda):
4899 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
4900 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
4901 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
4902
4903 * callint.c (Fcall_interactively): Don't use index var as event count.
4904
4905 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
4906 * mem-limits.h (SIZE): Remove; no longer used.
4907
4908 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
4909
4910 Remove unnecessary casts.
4911 * xterm.c (x_term_init):
4912 * xfns.c (x_set_border_pixel):
4913 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
4914 These aren't needed now that we assume ANSI C.
4915
4916 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
4917 It's more likely to cause problems (due to unsigned overflow)
4918 than to cure them.
4919
4920 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
4921
4922 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
4923
4924 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
4925
4926 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
4927
4928 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
4929
4930 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
4931
4932 GLYPH_CODE_FACE returns EMACS_INT, not int.
4933 * dispextern.h (merge_faces):
4934 * xfaces.c (merge_faces):
4935 * xdisp.c (get_next_display_element, next_element_from_display_vector):
4936 Don't assume EMACS_INT fits in int.
4937
4938 * character.h (CHAR_VALID_P): Remove unused parameter.
4939 * fontset.c, lisp.h, xdisp.c: All uses changed.
4940
4941 * editfns.c (Ftranslate_region_internal): Omit redundant test.
4942
4943 * fns.c (concat): Minor tuning based on overflow analysis.
4944 This doesn't fix any bugs. Use int to hold character, instead
4945 of constantly refetching from Emacs object. Use XFASTINT, not
4946 XINT, for value known to be a character. Don't bother comparing
4947 a single byte to 0400, as it's always less.
4948
4949 * floatfns.c (Fexpt):
4950 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
4951
4952 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
4953 for characters.
4954
4955 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
4956
4957 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
4958 Without this fix, on a 64-bit host (aset S 0 4294967386) would
4959 incorrectly succeed when S was a string, because 4294967386 was
4960 truncated before it was used.
4961
4962 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
4963 Otherwise, an out-of-range integer could cause undefined behavior
4964 on a 64-bit host.
4965
4966 * composite.c: Use int, not EMACS_INT, for characters.
4967 (fill_gstring_body, composition_compute_stop_pos): Use int, not
4968 EMACS_INT, for values that are known to be in character range.
4969 This doesn't fix any bugs but is the usual style inside Emacs and
4970 may generate better code on 32-bit machines.
4971
4972 Make sure a 64-bit char is never passed to ENCODE_CHAR.
4973 This is for reasons similar to the recent CHAR_STRING fix.
4974 * charset.c (Fencode_char): Check that character arg is actually
4975 a character. Pass an int to ENCODE_CHAR.
4976 * charset.h (ENCODE_CHAR): Verify that the character argument is no
4977 wider than 'int', as a compile-time check to prevent future regressions
4978 in this area.
4979
4980 * character.c (char_string): Remove unnecessary casts.
4981
4982 Make sure a 64-bit char is never passed to CHAR_STRING.
4983 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
4984 by silently ignoring the top 32 bits, allowing some values
4985 that were far too large to be valid characters.
4986 * character.h: Include <verify.h>.
4987 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
4988 arguments are no wider than unsigned, as a compile-time check
4989 to prevent future regressions in this area.
4990 * data.c (Faset):
4991 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
4992 (Fsubst_char_in_region):
4993 * fns.c (concat):
4994 * xdisp.c (decode_mode_spec_coding):
4995 Adjust to CHAR_STRING's new requirement.
4996 * editfns.c (Finsert_char, Fsubst_char_in_region):
4997 * fns.c (concat): Check that character args are actually
4998 characters. Without this test, these functions did the wrong
4999 thing with wildly out-of-range values on 64-bit hosts.
5000
5001 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
5002 These casts should not be needed on 32-bit hosts, either.
5003 * keyboard.c (read_char):
5004 * lread.c (Fload): Remove casts to unsigned.
5005
5006 * lisp.h (UNSIGNED_CMP): New macro.
5007 This fixes comparison bugs on 64-bit hosts.
5008 (ASCII_CHAR_P): Use it.
5009 * casefiddle.c (casify_object):
5010 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
5011 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
5012 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
5013 * dispextern.h (FACE_FROM_ID):
5014 * keyboard.c (read_char): Use UNSIGNED_CMP.
5015
5016 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
5017 not to EMACS_INT, to avoid GCC warning.
5018
5019 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
5020
5021 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
5022 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
5023 isn't needed on 32-bit machines.
5024
5025 * buffer.c (Fgenerate_new_buffer_name):
5026 Use EMACS_INT for count, not int.
5027 (advance_to_char_boundary): Return EMACS_INT, not int.
5028
5029 * data.c (Qcompiled_function): Now static.
5030
5031 * window.c (window_body_lines): Now static.
5032
5033 * image.c (gif_load): Rename local to avoid shadowing.
5034
5035 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
5036 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
5037 * alloc.c (make_save_value): Integer argument is now of type
5038 ptrdiff_t, not int.
5039 (mark_object): Use ptrdiff_t, not int.
5040 * lisp.h (pD): New macro.
5041 * print.c (print_object): Use it.
5042
5043 * alloc.c: Use EMACS_INT, not int, to count objects.
5044 (total_conses, total_markers, total_symbols, total_vector_size)
5045 (total_free_conses, total_free_markers, total_free_symbols)
5046 (total_free_floats, total_floats, total_free_intervals)
5047 (total_intervals, total_strings, total_free_strings):
5048 Now EMACS_INT, not int. All uses changed.
5049 (Fgarbage_collect): Compute overall total using a double, so that
5050 integer overflow is less likely to be a problem. Check for overflow
5051 when converting back to an integer.
5052 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
5053 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
5054 These were 'int' variables that could overflow on 64-bit hosts;
5055 they were never used, so remove them instead of repairing them.
5056 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.

5075 size_t overflow on (unusual) hosts where SIZE_MAX <= min
5076 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
5077 and ptrdiff_t and EMACS_INT are both 64 bits.

5648 Support character positions inside a run of characters covered by a
5649 display string.
5650 (bidi_paragraph_init, bidi_resolve_explicit_1)
5651 (bidi_level_of_next_char): Call bidi_fetch_char and

5658 instead of using explicit *_CHAR codes.
5659 (bidi_resolve_explicit, bidi_resolve_weak):
5660 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
5661 bidirectional text is supported only in multibyte buffers.

5670 were just reseat()'ed to a new position.
5671
5672 * xdisp.c (set_cursor_from_row): Set start and stop points
5673 according to the row's direction when priming the loop that looks
5674 for the glyph on which to display cursor.
5675 (single_display_spec_intangible_p): Function deleted.
5676 (display_prop_intangible_p): Reimplement to call
5677 handle_display_spec instead of single_display_spec_intangible_p.
5678 Accept 3 additional arguments needed by handle_display_spec.
5679 This fixes incorrect cursor motion across display property with complex
5680 values: lists, `(when COND...)' forms, etc.
5681 (single_display_spec_string_p): Support property values that are
5682 lists with the argument STRING its top-level element.
5683 (display_prop_string_p): Fix the condition for processing a
5684 property that is a list to be consistent with handle_display_spec.

5686 last portion of handle_display_prop.
5687 (compute_display_string_pos): Accept additional argument

5689 value of a `display' property is a "replacing spec".
5690 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
5691 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

5694 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
5695 frame_window_p members of struct bidi_it.
5696 (compute_display_string_pos, compute_display_string_end):

5719 All callers changed. (Bug#8762)
5720
5721 * gnutls.c: Use Emacs's memory allocators.
5722 Without this change, the gnutls library would invoke malloc etc.
5723 directly, which causes problems on non-SYNC_INPUT hosts, and which
5724 runs afoul of improving memory_full behavior. (Bug#8761)
5725 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
5726 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
5727 xfree instead of the default malloc, realloc, free.
5728 (Fgnutls_boot): No need to check for memory allocation failure,
5729 since xmalloc does that for us.

5751 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
5752 for hashes and hash indexes, instead of 'unsigned' and 'int'.
5753 * alloc.c (allocate_vectorlike):
5754 Check for overflow in vector size calculations.
5755 * ccl.c (ccl_driver):
5756 Check for overflow when converting EMACS_INT to int.

5758 need to be updated by these changes.
5759 * fns.c (make_hash_table, maybe_resize_hash_table):
5760 Check for integer overflow with large hash tables.
5761 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
5762 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
5763 (SXHASH_REDUCE): New macro.
5764 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
5765 Use it instead of discarding useful hash info with large hash values.
5766 (sxhash_float): New function.
5767 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
5768 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
5769 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
5770 Rewrite to use FIXNUM_BITS, as this simplifies things.
5771 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
5772 Adjust signatures to match updated version of code.
5773 (consing_since_gc): Now EMACS_INT, since a single hash table can
5774 use more than INT_MAX bytes.
5775

5885
5886 Avoid a sign-extension bug in crypto_hash_function.
5887 * fns.c (to_uchar): Define.
5888 (crypto_hash_function): Use it to convert some newly-signed
5889 variables to unsigned, to avoid sign-extension bugs. For example,
5890 without this change, (md5 "truc") would evaluate to
5891 45723a2aff78ff4fff7fff1114760e62 rather than the expected
5892 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
5893 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.

5896
5897 Integer overflow fixes.
5898
5899 * dbusbind.c: Serial number integer overflow fixes.
5900 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
5901 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
5902 to hold a serial number that is too large for a fixnum.
5903 (Fdbus_method_return_internal, Fdbus_method_error_internal):
5904 Check for serial numbers out of range. Decode any serial number
5905 that was so large that it became a float. (Bug#8722)
5906
5907 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
5908 (Fdbus_call_method, Fdbus_call_method_asynchronously):
5909 Use XFASTINT rather than XUINT when numbers are nonnegative.
5910 (xd_append_arg, Fdbus_method_return_internal):
5911 (Fdbus_method_error_internal): Likewise. Also, for unsigned
5912 arguments, check that Lisp number is nonnegative, rather than
5913 silently wrapping negative numbers around. (Bug#8722)
5914 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
5915 (Bug#8722)
5916
5917 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
5918
5919 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
5920
5921 ccl: Add integer overflow checks.
5922 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
5923 (IN_INT_RANGE): New macros.
5924 (ccl_driver): Use them to check for integer overflow when
5925 decoding a CCL program. Many of the new checks are whether XINT (x)
5926 fits in int; it doesn't always, on 64-bit hosts. The new version
5927 doesn't catch all possible integer overflows, but it's an
5928 improvement. (Bug#8719)
5929
5930 * alloc.c (make_event_array): Use XINT, not XUINT.
5931 There's no need for unsigned here.
5932
5933 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
5934 This follows up to the 2011-05-06 change that substituted uintptr_t
5935 for EMACS_INT. This case wasn't caught back then.
5936
5937 Rework Fformat to avoid integer overflow issues.
5938 * editfns.c: Include <float.h> unconditionally, as it's everywhere
5939 now (part of C89). Include <verify.h>.
5940 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
5941 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
5942 (Fformat): Avoid the prepass trying to compute sizes; it was only
5943 approximate and thus did not catch overflow reliably. Instead, walk
5944 through the format just once, formatting and computing sizes as we go,
5945 checking for integer overflow at every step, and allocating a larger
5946 buffer as needed. Keep track separately whether the format is
5947 multibyte. Keep only the most-recently calculated precision, rather
5948 than them all. Record whether each argument has been converted to
5949 string. Use EMACS_INT, not int, for byte and char and arg counts.
5950 Support field widths and precisions larger than INT_MAX. Avoid
5951 sprintf's undefined behavior with conversion specifications such as %#d
5952 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
5953 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
5954 formatting out-of-range floating point numbers with int
5955 formats. (Bug#8668)
5956
5957 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
5958
5959 * data.c: Avoid integer truncation in expressions involving floats.
5960 * data.c: Include <intprops.h>.
5961 (arith_driver): When there's an integer overflow in an expression
5962 involving floating point, convert the integers to floating point
5963 so that the resulting value does not suffer from catastrophic
5964 integer truncation. For example, on a 64-bit host (* 4
5965 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
5966 Do not rely on undefined behavior after integer overflow.
5967
5968 merge count_size_as_multibyte, parse_str_to_multibyte
5969 * character.c, character.h (count_size_as_multibyte):
5970 Rename from parse_str_to_multibyte; all uses changed.
5971 Check for integer overflow.
5972 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
5973 since it's now a duplicate of the other. This is more of
5974 a character than a buffer op, so better that it's in character.c.
5975 * fns.c, print.c: Adjust to above changes.
5976
5977 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
5978
5979 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
5980
5981 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5982
5983 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5984 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
5985 (x_clipboard_manager_save): Now static.
5986 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
5987
5988 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5989 (crypto_hash_function): Now static.
5990 Fix pointer signedness problems. Avoid unnecessary initializations.
5991
5992 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
5993
5994 * termhooks.h (Vselection_alist): Make it terminal-local.
5995
5996 * terminal.c (create_terminal): Initialize it.
5997
5998 * xselect.c: Support for clipboard managers.
5999 (Vselection_alist): Move to termhooks.h as terminal-local var.
6000 (LOCAL_SELECTION): New macro.
6001 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
6002 (symbol_to_x_atom): Remove gratuitous arg.
6003 (x_handle_selection_request, lisp_data_to_selection_data)
6004 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
6005 (x_own_selection, x_get_local_selection, x_convert_selection):
6006 New arg, specifying work frame. Use terminal-local Vselection_alist.
6007 (some_frame_on_display): Delete unused function.
6008 (Fx_own_selection_internal, Fx_get_selection_internal)
6009 (Fx_disown_selection_internal, Fx_selection_owner_p)
6010 (Fx_selection_exists_p): New optional frame arg.
6011 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
6012 (x_handle_selection_clear): Don't treat other terminals with the
6013 same keyboard specially. Use the terminal-local Vselection_alist.
6014 (x_clear_frame_selections): Use Frun_hook_with_args.
6015
6016 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
6017
6018 * xterm.h: Add support for those atoms.
6019
6020 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
6021
6022 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
6023 (converted_selections, conversion_fail_tag): New global variables.
6024 (x_selection_request_lisp_error): Free the above.
6025 (x_get_local_selection): Remove unnecessary code.
6026 (x_reply_selection_request): Args changed; handle arbitrary array
6027 of converted selections stored in converted_selections.
6028 Separate the XChangeProperty and SelectionNotify steps.
6029 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
6030 (x_convert_selection): New function.
6031 (x_handle_selection_event): Simplify.
6032 (x_get_foreign_selection): Don't ignore incoming requests while
6033 waiting for an answer; this will fail when we implement
6034 SAVE_TARGETS, and seems unnecessary anyway.
6035 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
6036 (Vx_sent_selection_functions): Doc fix.
6037
6038 2011-05-26 Leo Liu <sdl.web@gmail.com>
6039
6040 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
6041
6042 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6043
6044 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
6045
6046 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
6047 for fringe update if it has periodic bitmap.
6048 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
6049 and fringe_bitmap_periodic_p.
6050
6051 * fringe.c (get_fringe_bitmap_data): New function.
6052 (draw_fringe_bitmap_1, update_window_fringes): Use it.
6053 (update_window_fringes): Record periodicity of fringe bitmap in glyph
6054 row. Mark glyph row for fringe update if periodicity changed.
6055
6056 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
6057 for fringe update unless it has periodic bitmap.
6058
6059 2011-05-25 Kenichi Handa <handa@m17n.org>
6060
6061 * xdisp.c (get_next_display_element): Set correct it->face_id for
6062 a static composition.
6063
6064 2011-05-24 Leo Liu <sdl.web@gmail.com>
6065
6066 * deps.mk (fns.o):
6067 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
6068
6069 * fns.c (crypto_hash_function, Fsha1): New function.
6070 (Fmd5): Use crypto_hash_function.
6071 (syms_of_fns): Add Ssha1.
6072
6073 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
6074
6075 * gnutls.c: Remove unused macros.
6076 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
6077 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
6078 Remove macros that are defined and never used.
6079 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
6080
6081 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
6082
6083 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
6084 (Fx_get_selection_internal): Minor cleanup.
6085 (Fx_own_selection_internal): Rename arguments for consistency with
6086 select.el.
6087
6088 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
6089
6090 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
6091
6092 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
6093
6094 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
6095
6096 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6097
6098 * dispnew.c (scrolling_window): Don't exclude the case that the
6099 last enabled row in the desired matrix touches the bottom boundary.
6100
6101 2011-05-21 Glenn Morris <rgm@gnu.org>
6102
6103 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
6104 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
6105 and add some more files.
6106
6107 2011-05-20 Eli Zaretskii <eliz@gnu.org>
6108
6109 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
6110 report_file_error introduced by the change from 2011-05-07.
6111
6112 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
6113
6114 * systime.h (Time): Define only if emacs is defined.
6115 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
6116 where the include path doesn't have X11/X.h by default. See
6117 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
6118
6119 2011-05-20 Kenichi Handa <handa@m17n.org>
6120
6121 * composite.c (find_automatic_composition): Fix previous change.
6122
6123 2011-05-20 Glenn Morris <rgm@gnu.org>
6124
6125 * lisp.mk: New file, split from Makefile.in.
6126 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
6127 (shortlisp): Remove.
6128 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
6129
6130 2011-05-19 Glenn Morris <rgm@gnu.org>
6131
6132 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
6133 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
6134 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
6135 (lisp): Set the order to that of loadup.el.
6136 (shortlisp): Make it a copy of $lisp.
6137 (SOME_MACHINE_LISP): Remove.
6138 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
6139 Use just $shortlisp, not $SOME_MACHINE_LISP too.
6140
6141 2011-05-18 Kenichi Handa <handa@m17n.org>
6142
6143 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
6144 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
6145 (find_automatic_composition): Mostly rewrite for efficiency.
6146
6147 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
6148
6149 * makefile.w32-in: Update dependencies.
6150
6151 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
6152
6153 * menu.c: Include limits.h (fixes the MS-Windows build broken by
6154 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
6155
6156 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
6157
6158 Fix some integer overflow issues, such as string length overflow.
6159
6160 * insdel.c (count_size_as_multibyte): Check for string overflow.
6161
6162 * character.c (lisp_string_width): Check for string overflow.
6163 Use EMACS_INT, not int, for string indexes and lengths; in
6164 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
6165 the resulting string length overflows an EMACS_INT; instead,
6166 report a string overflow if no precision given. When checking for
6167 precision exhaustion, use a check that cannot possibly have
6168 integer overflow. (Bug#8675)
6169 * character.h (lisp_string_width): Adjust to new signature.
6170
6171 * alloc.c (string_overflow): New function.
6172 (Fmake_string): Use it. This doesn't change behavior, but saves
6173 a few bytes and will simplify future changes.
6174 * character.c (string_escape_byte8): Likewise.
6175 * lisp.h (string_overflow): New decl.
6176
6177 Fixups, following up to the user-interface timestamp change.
6178 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
6179 for UI timestamps, instead of unsigned long.
6180 * msdos.c (mouse_get_pos): Likewise.
6181 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
6182 * w32gui.h (Time): Define by including "systime.h" rather than by
6183 declaring it ourselves. (Bug#8664)
6184
6185 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
6186 * image.c (clear_image_cache): Likewise.
6187
6188 * term.c (term_mouse_position): Don't assume time_t wraparound.
6189
6190 Be more systematic about user-interface timestamps.
6191 Before, the code sometimes used 'Time', sometimes 'unsigned long',
6192 and sometimes 'EMACS_UINT', to represent these timestamps.
6193 This change causes it to use 'Time' uniformly, as that's what X uses.
6194 This makes the code easier to follow, and makes it easier to catch
6195 integer overflow bugs such as Bug#8664.
6196 * frame.c (Fmouse_position, Fmouse_pixel_position):
6197 Use Time, not unsigned long, for user-interface timestamps.
6198 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
6199 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
6200 * keyboard.h (last_event_timestamp): Likewise.
6201 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
6202 * menu.h (xmenu_show): Likewise.
6203 * term.c (term_mouse_position): Likewise.
6204 * termhooks.h (struct input_event.timestamp): Likewise.
6205 (struct terminal.mouse_position_hook): Likewise.
6206 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
6207 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
6208 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
6209 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
6210 what it was before.
6211 * menu.h, termhooks.h: Include "systime.h", for Time.
6212
6213 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
6214 Don't assume that the difference between two unsigned long values
6215 can fit into an integer. At this point, we know button_down_time
6216 <= event->timestamp, so the difference must be nonnegative, so
6217 there's no need to cast the result if double-click-time is
6218 nonnegative, as it should be; check that it's nonnegative, just in
6219 case. This bug is triggered when events are more than 2**31 ms
6220 apart (about 25 days). (Bug#8664)
6221
6222 * xselect.c (last_event_timestamp): Remove duplicate decl.
6223 (x_own_selection): Remove needless cast to unsigned long.
6224
6225 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
6226 that always fit in int. Use a sentinel instead of a counter, to
6227 avoid a temp and to allay GCC's concerns about possible int overflow.
6228 * frame.h (struct frame): Use int for menu_bar_items_used
6229 instead of EMACS_INT, since it always fits in int.
6230
6231 * menu.c (grow_menu_items): Check for int overflow.
6232
6233 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
6234
6235 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
6236 Before, the code was not consistent. These values cannot exceed
6237 2**31 - 1 so there's no need to make them unsigned.
6238 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
6239 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
6240 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
6241 as modifiers.
6242 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
6243
6244 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
6245 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
6246 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
6247 presumably because the widths might not match.
6248
6249 * window.c (size_window): Avoid needless test at loop start.
6250
6251 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
6252
6253 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
6254
6255 2011-05-12 Drew Adams <drew.adams@oracle.com>
6256
6257 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
6258
6259 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6260
6261 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
6262 `width' to `bar_area_x' and `bar_area_width', respectively.
6263 (x_scroll_run): Take account of fringe background extension.
6264
6265 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
6266 Rename local vars `left' and `width' to `bar_area_x' and
6267 `bar_area_width', respectively.
6268 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
6269 background extension.
6270
6271 2011-05-10 Jim Meyering <meyering@redhat.com>
6272
6273 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
6274
6275 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
6276
6277 * image.c (Finit_image_library): Return t for built-in image types,
6278 like pbm and xbm. (Bug#8640)
6279
6280 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
6281
6282 * w32menu.c (set_frame_menubar): Fix submenu allocation.
6283
6284 2011-05-07 Eli Zaretskii <eliz@gnu.org>
6285
6286 * w32console.c (Fset_screen_color): Doc fix.
6287 (Fget_screen_color): New function.
6288 (syms_of_ntterm): Defsubr it.
6289
6290 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
6291 unlink the temporary file if Fcall_process didn't create it in the
6292 first place.
6293 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
6294 child process will be redirected to a file specified with `:file'.
6295 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
6296 cue to call_process_cleanup not to close that handle.
6297
6298 2011-05-07 Ben Key <bkey76@gmail.com>
6299
6300 * makefile.w32-in: The bootstrap-temacs rule now makes use of
6301 one of two shell specific rules, either bootstrap-temacs-CMD or
6302 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
6303 to the previous implementation of the bootstrap-temacs rule.
6304 The bootstrap-temacs-CMD rule is similar to the previous
6305 implementation of the bootstrap-temacs rule except that it
6306 makes use of the ESC_CFLAGS variable instead of the CFLAGS
6307 variable.
6308
6309 These changes, along with some changes to nt/configure.bat,
6310 nt/gmake.defs, and nt/nmake.defs, are required to extend my
6311 earlier fix to add support for --cflags and --ldflags options
6312 that include quotes so that it works whether make uses cmd or
6313 sh as the shell.
6314
6315 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
6316
6317 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
6318 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
6319 is a constant.
6320 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
6321 a string. Handle both cases.
6322 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
6323 (Fdbus_register_method): Use Qinvalid_function.
6324
6325 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6326
6327 * makefile.w32-in: Update dependencies.
6328 (LISP_H): Add inttypes.h and stdin.h.
6329 (PROCESS_H): Add unistd.h.
6330
6331 2011-05-06 Eli Zaretskii <eliz@gnu.org>
6332
6333 * lread.c: Include limits.h (fixes the MS-Windows build broken by
6334 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
6335
6336 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
6337
6338 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
6339
6340 * term.c (vfatal): Remove stray call to va_end.
6341 It's not needed and the C Standard doesn't allow it here anyway.
6342
6343 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
6344 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
6345
6346 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
6347 bytes.
6348
6349 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
6350
6351 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
6352
6353 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
6354
6355 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
6356
6357 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
6358
6359 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
6360 * charset.c (Fdefine_charset_internal): Don't initialize
6361 charset.code_space[15]. The value was garbage, on hosts with
6362 32-bit int (Bug#8600).
6363
6364 * lread.c (read_integer): Be more consistent with string-to-number.
6365 Use string_to_number to do the actual conversion; this avoids
6366 rounding errors and fixes some other screwups. Without this fix,
6367 for example, #x1fffffffffffffff was misread as -2305843009213693952.
6368 (digit_to_number): Move earlier, for benefit of read_integer.
6369 Return -1 if the digit is out of range for the base, -2 if it is
6370 not a digit in any supported base. (Bug#8602)
6371
6372 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
6373
6374 * dispnew.c (scrolling_window): Return 1 if we scrolled,
6375 to match comment at start of function. This also removes a
6376 GCC warning about overflow in a 32+64-bit port.
6377
6378 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
6379
6380 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
6381 Reported by Stefan Monnier in
6382 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
6383 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6384 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
6385
6386 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
6387 (EMACS_UINTPTR): Likewise, with uintptr_t.
6388
6389 * lisp.h: Prefer 64-bit EMACS_INT if available.
6390 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
6391 on 32-bit hosts that have 64-bit int, so that they can access
6392 large files.
6393 However, temporarily disable this change unless the temporary
6394 symbol WIDE_EMACS_INT is defined.
6395
6396 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
6397
6398 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
6399 This removes an assumption that EMACS_INT and long are the same
6400 width as pointers. The assumption is true for Emacs porting targets
6401 now, but we want to make other targets possible.
6402 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6403 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6404 In the rest of the code, change types of integers that hold casted
6405 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6406 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6407 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6408 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6409 No need to cast type when ORing.
6410 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6411 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6412 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6413 assume EMACS_INT is the same width as char *.
6414 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6415 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6416 Remove no-longer-needed casts.
6417 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6418 (xg_tool_bar_help_callback, xg_make_tool_item):
6419 Use EMACS_INTPTR to hold an integer
6420 that will be cast to void *; this can avoid a GCC warning
6421 if EMACS_INT is not the same width as void *.
6422 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6423 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6424 (current_message_1, set_message_1):
6425 Use a local to convert to proper width without a cast.
6426 * xmenu.c (dialog_selection_callback): Likewise.
6427
6428 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6429 Also, don't assume VALBITS / RAND_BITS is less than 5,
6430 and don't rely on undefined behavior when shifting a 1 left into
6431 the sign bit.
6432 * lisp.h (get_random): Change signature to match.
6433
6434 * lread.c (hash_string): Use size_t, not int, for hash computation.
6435 Normally we prefer signed values; but hashing is special, because
6436 it's better to use unsigned division on hash table sizes so that
6437 the remainder is nonnegative. Also, size_t is the natural width
6438 for hashing into memory. The previous code used 'int', which doesn't
6439 retain enough info to hash well into very large tables.
6440 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6441
6442 * dbusbind.c: Don't possibly lose pointer info when converting.
6443 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6444 Use XPNTR rather than XHASH, so that the high-order bits of
6445 the pointer aren't lost when converting through void *.
6446
6447 * eval.c (Fautoload): Don't double-shift a pointer.
6448
6449 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6450
6451 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6452
6453 * gnutls.c (DEF_GNUTLS_FN):

6456 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6457
6458 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6459 marker. (Bug#8610)
6460
6461 2011-05-05 Eli Zaretskii <eliz@gnu.org>

6483 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
6484 Remove unused parameter `fildes'.
6485 * process.c (read_process_output, send_process): Don't pass it.
6486

6490 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
6491 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
6492
6493 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6494
6495 Implement dynamic loading of GnuTLS on Windows.

6533 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
6534 instead of gnutls_record_check_pending.

6562 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
6563 (Qgnutls_bootprop_callbacks_verify): Make static.
6564
6565 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
6566
6567 * callproc.c: Indentation fixup.
6568
6569 * sysdep.c (wait_for_termination_1): Make static.
6570 (wait_for_termination, interruptible_wait_for_termination):
6571 Move after wait_for_termination_1.
6572
6573 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
6574
6575 * sysdep.c (interruptible_wait_for_termination): New function
6576 which is like wait_for_termination, but allows keyboard
6577 interruptions.
6578
6579 * callproc.c (Fcall_process): Add (:file "file") as an option for
6580 the STDOUT buffer.
6581 (Fcall_process_region): Ditto.
6582
6583 2011-04-30 Eli Zaretskii <eliz@gnu.org>

6602 space for up to 2 characters produced in a loop.
6603 (decode_coding_iso_2022): Abort if there isn't enough place in
6604 charbuf for the composition carryover bytes.

6639 size if the message was truncated. (Bug#8545).
6640
6641 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6642
6643 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
6644 (Fx_window_property): #if-0 the whole functions, not just the bodies.
6645
6646 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6647
6648 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
6649
6650 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
6651
6652 * makefile.w32-in: Update dependencies.
6653
6654 2011-04-27 Eli Zaretskii <eliz@gnu.org>
6655
6656 Improve `doprnt' and its usage. (Bug#8545)
6657 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
6658 `format_end'. Remove support for %l as a conversion specifier.
6659 Don't use xrealloc. Improve diagnostics when the %l size modifier
6660 is used. Update the commentary.
6661
6662 * eval.c (verror): Simplify calculation of size_t.
6663
6664 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
6665 messages.
6666
6667 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)

6683 Remove unused local.
6684 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
6685
6686 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
6687 GCC 4.6.0 optimizes based on type-based alias analysis.
6688 For example, if b is of type struct buffer * and v of type struct
6689 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
6690 != &v->size, and therefore "v->size = 1; b->size = 2; return
6691 v->size;" must therefore return 1. This assumption is incorrect
6692 for Emacs, since it type-puns struct Lisp_Vector * with many other
6693 types. To fix this problem, this patch adds a new type struct
6694 vectorlike_header that documents the constraints on layout of vectors
6695 and pseudovectors, and helps optimizing compilers not get fooled
6696 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
6697 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
6698 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
6699 the size member.
6700 (XSETPVECTYPE): Rewrite in terms of new macro.
6701 (XSETPVECTYPESIZE): New macro, specifying both type and size.
6702 This is a bit clearer, and further avoids the possibility of
6703 undesirable aliasing.
6704 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
6705 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
6706 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
6707 since Lisp_Subr is a special case (no "next" field).
6708 (ASIZE): Now uses header.size rather than size.
6709 All previous uses of XVECTOR (foo)->size replaced to use this macro,
6710 to avoid the hassle of writing XVECTOR (foo)->header.size.
6711 (struct vectorlike_header): New type.
6712 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
6713 object, to help avoid aliasing.
6714 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
6715 (SUBRP): Likewise, since Lisp_Subr is a special case.
6716 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
6717 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
6718 (struct Lisp_Hash_Table): Combine first two members into a single
6719 struct vectorlike_header member. All uses of "size" and "next" members
6720 changed to be "header.size" and "header.next".
6721 * buffer.h (struct buffer): Likewise.
6722 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
6723 * frame.h (struct frame): Likewise.
6724 * process.h (struct Lisp_Process): Likewise.
6725 * termhooks.h (struct terminal): Likewise.
6726 * window.c (struct save_window_data, struct saved_window): Likewise.
6727 * window.h (struct window): Likewise.
6728 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
6729 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
6730 * buffer.c (init_buffer_once): Likewise.
6731 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
6732 special case.
6733 * process.c (Fformat_network_address): Use local var for size,
6734 for brevity.
6735
6736 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
6737
6738 Make the Lisp reader and string-to-float more consistent (Bug#8525)
6739 * data.c (atof): Remove decl; no longer used or needed.
6740 (digit_to_number): Move to lread.c.
6741 (Fstring_to_number): Use new string_to_number function, to be
6742 consistent with how the Lisp reader treats infinities and NaNs.
6743 Do not assume that floating-point numbers represent EMACS_INT
6744 without losing information; this is not true on most 64-bit hosts.
6745 Avoid double-rounding errors, by insisting on integers when
6746 parsing non-base-10 numbers, as the documentation specifies.
6747 * lisp.h (string_to_number): New decl, replacing ...
6748 (isfloat_string): Remove.
6749 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
6750 (read1): Do not accept +. and -. as integers; this
6751 appears to have been a coding error. Similarly, do not accept
6752 strings like +-1e0 as floating point numbers. Do not report
6753 overflow for integer overflows unless the base is not 10 which
6754 means we have no simple and reliable way to continue.
6755 Break out the floating-point parsing into a new
6756 function string_to_number, so that Fstring_to_number parses
6757 floating point numbers consistently with the Lisp reader.
6758 (digit_to_number): Move here from data.c. Make it static inline.
6759 (E_CHAR, EXP_INT): Remove, replacing with ...
6760 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
6761 (string_to_number): New function, replacing isfloat_string.
6762 This function checks for valid syntax and produces the resulting
6763 Lisp float number too. Rework it so that string-to-number
6764 no longer mishandles examples like "1.0e+". Use strtoumax,
6765 so that overflow for non-base-10 numbers is reported only when
6766 there's no portable and simple way to convert to floating point.
6767
6768 * textprop.c (set_text_properties_1): Rewrite for clarity,
6769 and to avoid GCC warning about integer overflow.
6770
6771 * intervals.h (struct interval): Use EMACS_INT for members
6772 where EMACS_UINT might cause problems. See
6773 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
6774 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
6775 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
6776 All uses changed.
6777 (offset_intervals): Tell GCC not to worry about length overflow
6778 when negating a negative length.
6779
6780 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
6781 (overrun_check_free): Likewise.
6782
6783 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
6784 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
6785 word size.
6786
6787 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6788 (gnutls_make_error): Rename local to avoid shadowing.
6789 (gnutls_emacs_global_deinit): ifdef out; not used.
6790 (Fgnutls_boot): Use const for pointer to readonly storage.
6791 Comment out unused local. Fix pointer signedness problems.
6792
6793 * lread.c (openp): Don't stuff size_t into an 'int'.
6794 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
6795 about possible signed overflow.
6796
6797 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6798 (GDK_KEY_g): Don't define if already defined.
6799 (xg_prepare_tooltip): Avoid pointer signedness problem.
6800 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
6801
6802 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
6803 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
6804
6805 * xfns.c (Fx_window_property): Simplify a bit,
6806 to make a bit faster and to avoid GCC 4.6.0 warning.
6807 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
6808
6809 * fns.c (internal_equal): Don't assume size_t fits in int.
6810
6811 * alloc.c (compact_small_strings): Tighten assertion a little.
6812
6813 Replace pEd with more-general pI, and fix some printf arg casts.
6814 * lisp.h (pI): New macro, generalizing old pEd macro to other
6815 conversion specifiers. For example, use "...%"pI"d..." rather
6816 than "...%"pEd"...".
6817 (pEd): Remove. All uses replaced with similar uses of pI.
6818 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
6819 * alloc.c (check_pure_size): Don't overflow by converting size to int.
6820 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
6821 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
6822 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
6823 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
6824 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
6825 64-bit hosts.
6826 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
6827 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
6828 * print.c (safe_debug_print, print_object): Likewise.
6829 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
6830 to int.
6831 Use pI instead of if-then-else-abort. Use %p to avoid casts,
6832 avoiding the 0 flag, which is not portable.
6833 * process.c (Fmake_network_process): Use pI to avoid cast.
6834 * region-cache.c (pp_cache): Likewise.
6835 * xdisp.c (decode_mode_spec): Likewise.
6836 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
6837 behavior on 64-bit hosts with printf arg.
6838 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
6839 (x_stop_queuing_selection_requests): Likewise.
6840 (x_get_window_property): Don't truncate byte count to an 'int'
6841 when tracing.
6842
6843 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
6844 here, since it parses constructs like leading '-' and spaces,
6845 which are not wanted; and it overflows with large numbers.
6846 Instead, simply match F[0-9]+, which is what is wanted anyway.
6847
6848 * alloc.c: Remove unportable assumptions about struct layout.
6849 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
6850 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
6851 (allocate_vectorlike, make_pure_vector): Use the new macros,
6852 plus offsetof, to remove unportable assumptions about struct layout.
6853 These assumptions hold on all porting targets that I know of, but
6854 they are not guaranteed, they're easy to remove, and removing them
6855 makes further changes easier.
6856
6857 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
6858 This doesn't fix a bug but makes the code clearer.
6859 (string_overrun_cookie): Now const. Use initializers that
6860 don't formally overflow signed char, to avoid warnings.
6861 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
6862 can cause Emacs to crash when string overrun checking is enabled.
6863 (allocate_buffer): Don't assume sizeof (struct buffer) is a
6864 multiple of sizeof (EMACS_INT); it need not be, if
6865 alignof(EMACS_INT) < sizeof (EMACS_INT).
6866 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
6867
6868 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
6869
6870 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

6873
6874 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
6875 supposed to be handshaking. (Bug#8556)
6876 Reported by Paul Eggert <eggert@cs.ucla.edu>.
6877
6878 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
6879
6880 * lisp.h (Qdebug): List symbol.
6881 * eval.c (Qdebug): Restore global linkage.
6882 * keyboard.c (debug-on-event): New variable.
6883 (handle_user_signal): Break into debugger when debug-on-event
6884 matches the current signal symbol.
6885
6886 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
6887
6888 * alloc.c (check_sblock, check_string_bytes)
6889 (check_string_free_list): Convert to standard C.
6890
6891 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

6893 * w32.c (emacs_gnutls_push): Fix typo.
6894
6895 2011-04-25 Eli Zaretskii <eliz@gnu.org>
6896
6897 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
6898 "cast to pointer from integer of different size".
6899
6900 Improve doprnt and its use in verror. (Bug#8545)
6901 * doprnt.c (doprnt): Document the set of format control sequences
6902 supported by the function. Use SAFE_ALLOCA instead of always
6903 using `alloca'.
6904
6905 * eval.c (verror): Don't limit the buffer size at size_max-1, that
6906 is one byte too soon. Don't use xrealloc; instead xfree and
6907 xmalloc anew.
6908
6909 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
6910
6911 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
6912 callbacks stage.
6913
6914 * gnutls.c: Renamed global_initialized to
6915 gnutls_global_initialized. Added internals for the
6916 :verify-hostname-error, :verify-error, and :verify-flags
6917 parameters of `gnutls-boot' and documented those parameters in the
6918 docstring. Start callback support.
6919 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
6920 unless a fatal error occurred. Call gnutls_alert_send_appropriate
6921 on error. Return error code.
6922 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
6923 (emacs_gnutls_read): Likewise.
6924 (Fgnutls_boot): Return handshake error code.
6925 (emacs_gnutls_handle_error): New function.

6937 buffered some data internally if no FDs are set for TLS
6938 connections.
6939

6945
6946 * xdisp.c (handle_single_display_spec): Rename the
6947 display_replaced_before_p argument into display_replaced_p, to
6948 make it consistent with the commentary. Fix typos in the
6949 commentary.
6950
6951 * textprop.c (syms_of_textprop): Remove dead code.
6952 (copy_text_properties): Delete obsolete commentary about an
6953 interface that was deleted long ago. Fix typos in the description
6954 of arguments.

6957 to changes in oldXMenu/XMenu.h from 2011-04-16.
6958 <menu_help_message, prev_menu_help_message>: Constify.
6959 (IT_menu_make_room): menu->help_text is now `const char **';
6960 adjust.
6961
6962 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
6963 to changes in oldXMenu/XMenu.h from 2011-04-16.

6972
6973 * doprnt.c (doprnt): Improve commentary.
6974
6975 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
6976
6977 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
6978 them with etags.
6979
6980 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
6981 changes in globals.h immediately force recompilation.
6982 (TAGS): Depend on $(CURDIR)/m/intel386.h and
6983 $(CURDIR)/s/ms-w32.h.
6984 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
6985
6986 * character.c (Fchar_direction): Function deleted.
6987 (syms_of_character): Don't defsubr it.
6988 <char-direction-table>: Deleted.
6989
6990 2011-04-23 Eli Zaretskii <eliz@gnu.org>
6991
6992 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
6993 * doprnt.c: Include limits.h.
6994 (SIZE_MAX): New macro.
6995 (doprnt): Return a size_t value. 2nd arg is now size_t.
6996 Many local variables are now size_t instead of int or unsigned.
6997 Improve overflow protection. Support `l' modifier for integer
6998 conversions. Support %l conversion. Don't assume an EMACS_INT
6999 argument for integer conversions and for %c.
7000
7001 * lisp.h (doprnt): Restore prototype.
7002
7003 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
7004 $(SRC)/character.h.
7005

7009 (callint.o): Depend on character.h.
7010
7011 * eval.c (internal_lisp_condition_case): Include the handler
7012 representation in the error message.
7013 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
7014 when breaking from the loop.
7015
7016 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
7017
7018 * callint.c (Fcall_interactively): When displaying error message
7019 about invalid control letter, pass the character's codepoint, not
7020 a pointer to its multibyte form. Improve display of the character
7021 in octal and display also its hex code.
7022
7023 * character.c (char_string): Use %x to display the (unsigned)
7024 codepoint of an invalid character, to avoid displaying a bogus
7025 negative value.
7026
7027 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
7028 `error', not SYMBOL_NAME itself.
7029
7030 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
7031 character arguments to `error'.
7032
7033 * charset.c (check_iso_charset_parameter): Fix incorrect argument
7034 to `error' in error message about FINAL_CHAR argument. Make sure
7035 FINAL_CHAR is a character, and use %c when it is passed as
7036 argument to `error'.
7037

7079
7080 * dispextern.h (FACE_SUITABLE_FOR_ASCII_CHAR_P): Add missing
7081 definition for no-X builds.
7082
7083 2011-04-16 Paul Eggert <eggert@cs.ucla.edu>
7084
7085 Static checks with GCC 4.6.0 and non-default toolkits.
7086
7087 * s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF): Protoize decl.
7088
7089 * process.c (keyboard_bit_set): Define only if SIGIO.

7091 (send_process): Repair possible setjmp clobbering.
7092
7093 * s/usg5-4-common.h (SETUP_SLAVE_PTY): Don't pass extra arg to 'fatal'.
7094
7095 * eval.c: Include <stdio.h>, for vsnprintf on non-GNU/Linux hosts.
7096
7097 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.
7098
7099 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
7100 Define only if needed.
7101
7102 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
7103 by pacifying GCC about it. Maybe it's time to retire it?
7104 * xfaces.c (USG, __TIMEVAL__): Likewise.
7105
7106 * dispextern.h (struct redisplay_interface): Rename param
7107 to avoid shadowing.

7224
7225 * nsfont.m: Fixed bugs in ns_get_family and
7226 ns_descriptor_to_entity that were caused by using free to
7227 deallocate memory blocks that were allocated by xmalloc (via
7228 xstrdup). This caused Emacs to crash when compiled with
7229 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
7230 --enable-checking=xmallocoverrun). xfree is now used to
7231 deallocate these memory blocks.

7582 * buffer.c (buffer_count): Remove unused var.
7583
7584 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
7585 so that it's not optimized away.
7586 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
7587 * dispextern.h (bidi_dump_cached_states): Remove, since it's
7588 exported only to the debugger.
7589
7590 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
7591 * atimer.h (run_all_atimers): Remove; not exported.
7592
7593 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
7594 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
7595 was inaccessible from Lisp.
7596 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
7597 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
7598
7599 alloc.c: Import and export fewer symbols, and remove unused items.
7600 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
7601 is defined.
7602 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
7603 it's not optimized away by whole-program optimization.
7604 (message_enable_multibyte, free_misc): Remove.
7605 (catchlist, handlerlist, mark_backtrace):
7606 Declare only if BYTE_MARK_STACK.

7616 (mark_backtrace): Define only if BYTE_MARK_STACK.
7617 * xdisp.c (message_enable_multibyte): Now static.
7618
7619 Declare Lisp_Object Q* variables to be 'static' if not exported.
7620 This makes it easier for human readers (and static analyzers)
7621 to see whether these variables are used from other modules.
7622 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
7623 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
7624 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

7632 Remove decls of unexported vars.
7633 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
7634
7635 * lisp.h (DEFINE_FUNC): Make sname 'static'.
7636
7637 Make Emacs functions such as Fatom 'static' by default.
7638 This makes it easier for human readers (and static analyzers)
7639 to see whether these functions can be called from other modules.
7640 DEFUN now defines a static function. To make the function external
7641 so that it can be used in other C modules, use the new macro DEFUE.
7642 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
7643 (Finit_image_library):
7644 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
7645 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
7646 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
7647 Remove decls, since these functions are now static.
7648 (Funintern, Fget_internal_run_time): New decls, since these functions
7649 were already external.
7650
7651 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

7657 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
7658 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
7659 Mark functions with DEFUE instead of DEFUN,
7660 if they are used in other modules.
7661 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
7662 decls for now-static functions.
7663 * buffer.h (Fdelete_overlay): Remove decl.
7664 * callproc.c (Fgetenv_internal): Mark as internal.
7665 * composite.c (Fremove_list_of_text_properties): Remove decl.

7676 (Fremove_list_of_text_properties): Remove decls.
7677 * keyboard.c (Fthis_command_keys): Remove decl.
7678 (Fcommand_execute): New forward static decl.
7679 * keymap.c (Flookup_key): New forward static decl.
7680 (Fcopy_keymap): Now static.
7681 * keymap.h (Flookup_key): Remove decl.
7682 * process.c (Fget_process): New forward static decl.
7683 (Fprocess_datagram_address): Mark as internal.

7691

7693
7694 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
7695
7696 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
7697 change. (Bug#8496)
7698
7699 2011-04-13 Eli Zaretskii <eliz@gnu.org>
7700
7701 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
7702 when at ZV. (Bug#8487)
7703
7704 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
7705
7706 * charset.c (Fclear_charset_maps): Use xfree instead of free.
7707 (Bug#8437)
7708 * keyboard.c (parse_tool_bar_item): Likewise.
7709 * sound.c (sound_cleanup, alsa_close): Likewise.
7710 * termcap.c (tgetent): Likewise.
7711 * xfns.c (x_default_font_parameter): Likewise.
7712 * xsettings.c (read_and_apply_settings): Likewise.
7713
7714 * alloc.c (overrun_check_malloc, overrun_check_realloc)
7715 (overrun_check_free): Protoize.
7716
7717 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
7718
7719 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
7720 since callers should never pass a negative size.
7721 Change the signature to match that of plain 'read' and 'write'; see
7722 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
7723 * lisp.h: Update prototypes of emacs_write and emacs_read.
7724
7725 2011-04-11 Eli Zaretskii <eliz@gnu.org>
7726
7727 * xdisp.c (redisplay_window): Don't try to determine the character
7728 position of the scroll margin if the window start point w->startp
7729 is outside the buffer's accessible region. (Bug#8468)
7730
7731 2011-04-10 Eli Zaretskii <eliz@gnu.org>
7732
7733 Fix write-region and its subroutines for buffers > 2GB.
7734 * fileio.c (a_write, e_write): Modify declaration of arguments and
7735 local variables to support buffers larger than 2GB.
7736 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
7737
7738 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
7739 argument, local variables, and return value.
7740
7741 * lisp.h: Update prototypes of emacs_write and emacs_read.
7742
7743 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
7744
7745 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
7746
7747 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
7748
7749 Fix more problems found by GCC 4.6.0's static checks.
7750
7751 * xdisp.c (vmessage): Use a better test for character truncation.
7752
7753 * charset.c (load_charset_map): <, not <=, for optimization,
7754 and to avoid potential problems with integer overflow.
7755 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
7756 * casetab.c (set_identity, shuffle): Likewise.
7757 * editfns.c (Fformat): Likewise.
7758 * syntax.c (skip_chars): Likewise.
7759
7760 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
7761 This also lets GCC 4.6.0 generate slightly better loop code.
7762
7763 * callint.c (Fcall_interactively): <, not <=, for optimization.
7764 (Fcall_interactively): Count the number of arguments produced,
7765 not the number of arguments given. This is simpler and lets GCC
7766 4.6.0 generate slightly better code.
7767
7768 * ftfont.c: Distingish more carefully between FcChar8 and char.
7769 The previous code passed unsigned char * to a functions like
7770 strlen and xstrcasecmp that expect char *, which does not
7771 conform to the C standard.
7772 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
7773 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
7774 char * when the C standard requires it.
7775
7776 * keyboard.c (read_char): Remove unused var.
7777
7778 * eval.c: Port to Windows vsnprintf (Bug#8435).
7779 Include <limits.h>.
7780 (SIZE_MAX): Define if the headers do not.
7781 (verror): Do not give up if vsnprintf returns a negative count.
7782 Instead, grow the buffer. This ports to Windows vsnprintf, which
7783 does not conform to C99. Problem reported by Eli Zaretskii.
7784 Also, simplify the allocation scheme, by avoiding the need for
7785 calling realloc, and removing the ALLOCATED variable.
7786
7787 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
7788
7789 Remove invocations of doprnt, as Emacs now uses vsnprintf.
7790 But keep the doprint source code for now, as we might revamp it
7791 and use it again (Bug#8435).
7792 * lisp.h (doprnt): Remove.
7793 * Makefile.in (base_obj): Remove doprnt.o.
7794 * deps.mk (doprnt.o): Remove.
7795
7796 error: Print 32- and 64-bit integers portably (Bug#8435).
7797 Without this change, on typical 64-bit hosts error ("...%d...", N)
7798 was used to print both 32- and 64-bit integers N, which relied on
7799 undefined behavior.
7800 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
7801 * lisp.h (error, verror): Mark as printf-like functions.
7802 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
7803 Report overflow in size calculations when allocating printf buffer.
7804 Do not truncate output string at its first null byte.
7805 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
7806 Truncate the output at a character boundary, since vsnprintf does not
7807 do that.
7808 * charset.c (check_iso_charset_parameter): Convert internal
7809 character to string before calling 'error', since %c now has the
7810 printf meaning.
7811 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
7812 overflow when computing char to be passed to 'error'. Do not
7813 pass Lisp_Object to 'error'; pass the integer instead.
7814 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
7815 formatted with plain %d.
7816
7817 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
7818
7819 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
7820
7821 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
7822
7823 * xterm.c (x_catch_errors): Remove duplicate declaration.
7824
7825 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
7826
7827 * xdisp.c, lisp.h (message_nolog): Remove; unused.
7828
7829 2011-04-10 Jim Meyering <meyering@redhat.com>
7830
7831 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
7832 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
7833 return ssize_t not "int", and use size_t as the buffer length.
7834 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
7835 * gnutls.h: Update declarations.
7836 * process.c (read_process_output): Use ssize_t, to match.
7837 (send_process): Likewise.
7838
7839 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
7840
7841 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
7842
7843 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
7844
7845 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
7846 Use unsigned char, to match FcChar8 type definition.
7847
7848 * xterm.c (handle_one_xevent):
7849 * xmenu.c (create_and_show_popup_menu):
7850 * xselect.c (x_decline_selection_request)
7851 (x_reply_selection_request): Avoid type-punned deref of X events.
7852
7853 2011-04-09 Eli Zaretskii <eliz@gnu.org>
7854
7855 Fix some uses of `int' instead of EMACS_INT.
7856 * search.c (string_match_1, fast_string_match)
7857 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
7858 (scan_buffer, find_next_newline_no_quit)
7859 (find_before_next_newline, search_command, Freplace_match)
7860 (Fmatch_data): Make some `int' variables be EMACS_INT.
7861
7862 * xdisp.c (display_count_lines): 3rd argument and return value now
7863 EMACS_INT. All callers changed.
7864 (pint2hrstr): Last argument is now EMACS_INT.
7865
7866 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
7867 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
7868 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
7869 (decode_coding_utf_16, decode_coding_emacs_mule)
7870 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
7871 (decode_coding_ccl, decode_coding_charset)

7873 (decode_coding_iso_2022, decode_coding_emacs_mule)
7874 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
7875 <char_offset, last_offset>: Declare EMACS_INT.
7876 (encode_coding_utf_8, encode_coding_utf_16)
7877 (encode_coding_emacs_mule, encode_invocation_designation)
7878 (encode_designation_at_bol, encode_coding_iso_2022)
7879 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
7880 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
7881 Declare EMACS_INT.
7882 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
7883 (encode_invocation_designation): Last argument P_NCHARS is now
7884 EMACS_INT.
7885 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
7886 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
7887
7888 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
7889 All users changed.
7890
7891 * ccl.c (Fccl_execute_on_string): Declare some variables
7892 EMACS_INT.
7893
7894 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
7895

7903
7904 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
7905
7906 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
7907
7908 * keyboard.c (read_char): Call Lisp function help-form-show,
7909 instead of using internal_with_output_to_temp_buffer.
7910 (Qhelp_form_show): New var.
7911 (syms_of_keyboard): Use DEFSYM macro.
7912

7943
7944 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
7945 printf-like functions.
7946 (tiff_load): Add casts to remove these marks before passing them

7949 * eval.c (Fsignal): Remove excess argument to 'fatal'.
7950
7951 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
7952 This avoids several warnings with gcc -Wstrict-overflow.
7953 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
7954 directly, rather than having caller test rule sign. This avoids
7955 some unnecessary tests.
7956 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
7957 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
7958 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
7959
7960 * xfont.c (xfont_text_extents): Remove var that was set but not used.
7961 (xfont_open): Avoid unnecessary tests.
7962
7963 * composite.c (composition_gstring_put_cache): Use unsigned integer.
7964
7965 * composite.h, composite.c (composition_gstring_put_cache):
7966 Use EMACS_INT, not int, for length.
7967
7968 * composite.h (COMPOSITION_DECODE_REFS): New macro,
7969 breaking out part of COMPOSITION_DECODE_RULE.
7970 (COMPOSITION_DECODE_RULE): Use it.
7971 * composite.c (get_composition_id): Remove unused local vars,
7972 by using the new macro.
7973
7974 * textprop.c (set_text_properties_1): Change while to do-while,
7975 since the condition is always true at first.
7976
7977 * intervals.c (graft_intervals_into_buffer): Mark var as used.
7978 (interval_deletion_adjustment): Return unsigned value.
7979 All uses changed.
7980
7981 * process.c (list_processes_1, create_pty, read_process_output):
7982 (exec_sentinel): Remove vars that were set but not used.
7983 (create_pty): Remove unnecessary "volatile"s.
7984 (Fnetwork_interface_info): Avoid possibility of int overflow.

7991 (update_syntax_table): Use unsigned instead of int.
7992
7993 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
7994 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
7995 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
7996
7997 * print.c (print_error_message): Avoid int overflow.
7998
7999 * font.c (font_list_entities): Redo for clarity,
8000 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
8001
8002 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
8003 (font_score): Avoid potential overflow in diff calculation.
8004
8005 * fns.c (substring_both): Remove var that is set but not used.
8006 (sxhash): Redo loop for clarity and to avoid wraparound warning.
8007
8008 * eval.c (funcall_lambda): Rename local to avoid shadowing.
8009
8010 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
8011 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
8012 can always succeed if overflow has undefined behavior.
8013
8014 * search.c (boyer_moore, wordify): Remove vars set but not used.
8015 (wordify): Omit three unnecessary tests.
8016
8017 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

8021
8022 * dired.c (file_name_completion): Remove var that is set but not used.

8029 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
8030 Check for integer overflow on size calculations.
8031
8032 * buffer.c (Fprevious_overlay_change): Remove var that is set
8033 but not used.
8034
8035 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
8036 Remove vars that are set but not used.
8037 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

8039
8040 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
8041
8042 * image.c (lookup_image): Remove var that is set but not used.
8043 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
8044
8045 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
8046 that are set but not used.
8047
8048 * xfns.c (make_invisible_cursor): Don't return garbage
8049 if XCreateBitmapFromData fails (Bug#8410).
8050
8051 * xselect.c (x_get_local_selection, x_handle_property_notify):
8052 Remove vars that are set but not used.
8053
8054 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
8055 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
8056
8057 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
8058 Remove var that is set but not used.
8059 (scroll_bar_windows_size): Now size_t, not int.
8060 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
8061 Check for overflow.
8062
8063 * xfaces.c (realize_named_face): Remove vars that are set but not used.
8064 (map_tty_color) [!defined MSDOS]: Likewise.
8065
8066 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
8067
8068 * coding.c: Remove vars that are set but not used.
8069 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
8070 All callers changed.
8071 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
8072 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
8073 (decode_coding_charset): Remove vars that are set but not used.
8074
8075 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
8076 that is set but not used.
8077
8078 * print.c (print_object): Remove var that is set but not used.
8079
8080 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
8081 The gnulib version avoids calling malloc in the usual case,
8082 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
8083 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
8084 * filelock.c (current_lock_owner): Likewise.
8085 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
8086 * sysdep.c: Include allocator.h, careadlinkat.h.
8087 (emacs_no_realloc_allocator): New static constant.
8088 (emacs_readlink): New function.
8089 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
8090 ../lib/careadlinkat.h.
8091
8092 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
8093
8094 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
8095 first non-nil return value).
8096
8097 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
8098
8099 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
8100 if not defined (Bug#8403).
8101
8102 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
8103
8104 * xdisp.c (display_count_lines): Remove parameter `start',
8105 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
8106 (get_char_face_and_encoding): Remove parameter `multibyte_p',
8107 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

8115
8116 do not dereference NULL upon failed strdup
8117 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
8118 (ns_get_family): Likewise.
8119
8120 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
8121
8122 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
8123
8124 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
8125
8126 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
8127 later (Bug#8403).
8128
8129 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
8130
8131 Add lexical binding.
8132
8133 * window.c (Ftemp_output_buffer_show): New fun.
8134 (Fsave_window_excursion):
8135 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
8136
8137 * lread.c (lisp_file_lexically_bound_p): New function.
8138 (Fload): Bind Qlexical_binding.
8139 (readevalloop): Remove `evalfun' arg.
8140 Bind Qinternal_interpreter_environment.
8141 (Feval_buffer): Bind Qlexical_binding.
8142 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
8143 Mark as dynamic.
8144 (syms_of_lread): Declare `lexical-binding'.
8145
8146 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
8147
8148 * keyboard.c (eval_dyn): New fun.
8149 (menu_item_eval_property): Use it.
8150
8151 * image.c (parse_image_spec): Use Ffunctionp.
8152
8153 * fns.c (concat, mapcar1): Accept byte-code-functions.
8154
8155 * eval.c (Fsetq): Handle lexical vars.
8156 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
8157 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
8158 (FletX, Flet): Obey lexical binding.
8159 (Fcommandp): Handle closures.
8160 (Feval): New `lexical' arg.
8161 (eval_sub): New function extracted from Feval. Use it almost
8162 everywhere where Feval was used. Look up vars in lexical env.
8163 Handle closures.
8164 (Ffunctionp): Move from subr.el.
8165 (Ffuncall): Handle closures.
8166 (apply_lambda): Remove `eval_flags'.
8167 (funcall_lambda): Handle closures and new byte-code-functions.
8168 (Fspecial_variable_p): New function.
8169 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
8170 but without exporting it to Lisp.
8171
8172 * doc.c (Fdocumentation, store_function_docstring):
8173 * data.c (Finteractive_form): Handle closures.
8174
8175 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
8176 interactive spec.
8177
8178 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
8179 New byte-codes.
8180 (exec_byte_code): New function extracted from Fbyte_code to handle new
8181 calling convention for byte-code-functions. Add new byte-codes.
8182
8183 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
8184
8185 * alloc.c (Fmake_symbol): Init new `declared_special' field.
8186
8187 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8188
8189 * xdisp.c (redisplay_internal): Fix prototype.
8190
8191 2011-03-31 Eli Zaretskii <eliz@gnu.org>
8192
8193 * xdisp.c (SCROLL_LIMIT): New macro.
8194 (try_scrolling): Use it when setting scroll_limit.
8195 Limit scrolling to 100 screen lines.
8196 (redisplay_window): Even when falling back on "recentering",
8197 position point in the window according to scroll-conservatively,
8198 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
8199
8200 (try_scrolling): When point is above the window, allow searching
8201 as far as scroll_max, or one screenful, to compute vertical
8202 distance from PT to the scroll margin position. This prevents
8203 try_scrolling from unnecessarily failing when
8204 scroll-conservatively is set to a value slightly larger than the
8205 window height. Clean up the case of PT below the margin at bottom
8206 of window: scroll_max can no longer be INT_MAX. When aggressive
8207 scrolling is in use, don't let point enter the opposite scroll
8208 margin as result of the scroll.
8209 (syms_of_xdisp) <scroll-conservatively>: Document the
8210 threshold of 100 lines for never-recentering scrolling.
8211
8212 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8213
8214 * dispextern.h (move_it_by_lines):
8215 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
8216 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
8217 (message_log_check_duplicate): Remove parameters `prev_bol' and
8218 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
8219 (redisplay_internal): Remove parameter `preserve_echo_area',
8220 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
8221
8222 * indent.c (Fvertical_motion):
8223 * window.c (window_scroll_pixel_based, Frecenter):
8224 Don't pass `need_y_p' to `move_it_by_lines'.
8225
8226 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
8227
8228 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
8229 steal a few bits to be more compact.
8230 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
8231 Remove unneeded casts.
8232
8233 * bytecode.c (Fbyte_code): CAR and CDR can GC.
8234
8235 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
8236
8237 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
8238 binding" message (bug#7967).
8239
8240 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
8241
8242 Fix more problems found by GCC 4.6.0's static checks.
8243
8244 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
8245 Remove unused local var.
8246
8247 * editfns.c (Fmessage_box): Remove unused local var.
8248
8249 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
8250 (note_mode_line_or_margin_highlight, note_mouse_highlight):
8251 Omit unused local vars.
8252 * window.c (shrink_windows): Omit unused local var.
8253 * menu.c (digest_single_submenu): Omit unused local var.
8254 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
8255 Omit unused local var.
8256
8257 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
8258 Don't assume string length fits in int.
8259 (keyremap_step, read_key_sequence): Use size_t for sizes.
8260 (read_key_sequence): Don't check last_real_key_start redundantly.
8261
8262 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
8263 instead of alloca (Bug#8344).
8264
8265 * eval.c (Fbacktrace): Don't assume nargs fits in int.
8266 (Fbacktrace_frame): Don't assume nframes fits in int.
8267
8268 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
8269
8270 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
8271 concerns.
8272
8273 * term.c (produce_glyphless_glyph): Remove unnecessary test.
8274
8275 * cm.c (calccost): Turn while-do into do-while, for clarity.
8276
8277 * keyboard.c (syms_of_keyboard): Use the same style as later
8278 in this function when indexing through an array. This also
8279 works around GCC bug 48267.
8280
8281 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
8282
8283 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
8284
8285 * chartab.c (sub_char_table_ref_and_range): Redo for slight
8286 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
8287
8288 * keyboard.c, keyboard.h (num_input_events): Now size_t.
8289 This avoids undefined behavior on integer overflow, and is a bit
8290 more convenient anyway since it is compared to a size_t variable.
8291
8292 Variadic C functions now count arguments with size_t, not int.
8293 This avoids an unnecessary limitation on 64-bit machines, which
8294 caused (substring ...) to crash on large vectors (Bug#8344).
8295 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
8296 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
8297 All variadic functions and their callers changed accordingly.
8298 (struct gcpro.nvars): Now size_t, not int. All uses changed.
8299 * data.c (arith_driver, float_arith_driver): Likewise.
8300 * editfns.c (general_insert_function): Likewise.
8301 * eval.c (struct backtrace.nargs, interactive_p)
8302 (internal_condition_case_n, run_hook_with_args, apply_lambda)
8303 (funcall_lambda, mark_backtrace): Likewise.
8304 * fns.c (concat): Likewise.
8305 * frame.c (x_set_frame_parameters): Likewise.
8306 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
8307 0 if not found, not -1. All callers changed.
8308
8309 * alloc.c (garbage_collect): Don't assume stack size fits in int.
8310 (stack_copy_size): Now size_t, not int.
8311 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
8312
8313 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
8314
8315 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
8316 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
8317 All callers changed.
8318
8319 * lisp.h (multibyte_char_to_unibyte):
8320 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
8321 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
8322 * character.h (CHAR_TO_BYTE8):
8323 * cmds.c (internal_self_insert):
8324 * editfns.c (general_insert_function):
8325 * keymap.c (push_key_description):
8326 * search.c (Freplace_match):
8327 * xdisp.c (message_dolog, set_message_1): All callers changed.
8328
8329 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8330
8331 * keyboard.c (safe_run_hook_funcall): New function.
8332 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
8333 don't set the hook to nil, but remove the offending function instead.
8334 (Qcommand_hook_internal): Remove, unused.
8335 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define

8523
8524 Fix more problems found by GCC 4.5.2's static checks.
8525
8526 * coding.c (encode_coding_raw_text): Avoid unnecessary test
8527 the first time through the loop, since we know p0 < p1 then.
8528 This also avoids a gcc -Wstrict-overflow warning.
8529
8530 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
8531 leading to a memory leak, possible in functions like
8532 load_charset_map_from_file that can allocate an unbounded number
8533 of objects (Bug#8318).
8534
8535 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
8536 that could (at least in theory) be that large.
8537
8538 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
8539 This is less likely to overflow, and avoids undefined behavior if
8540 overflow does occur. All callers changed. Use strtoul to scan
8541 for the unsigned long integer.

8557
8558 * process.c (Fmake_network_process): Use socklen_t, not int,
8559 where POSIX says socklen_t is required in portable programs.
8560 This fixes a porting bug on hosts like 64-bit HP-UX, where
8561 socklen_t is wider than int (Bug#8277).
8562 (Fmake_network_process, server_accept_connection):
8563 (wait_reading_process_output, read_process_output):
8564 Likewise.
8565
8566 * process.c: Rename or move locals to avoid shadowing.

8574 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
8575
8576 Make tparam.h and terminfo.c consistent.
8577 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
8578 Include tparam.h instead, since it declares them.
8579 * cm.h (PC): Remove extern decl; tparam.h now does this.
8580 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
8581 * terminfo.c: Include tparam.h, to check interfaces.
8582 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
8583 (tparam): Adjust signature to match interface in tparam.h;
8584 this removes some undefined behavior. Check that outstring and len
8585 are zero, which they always are with Emacs.
8586 * tparam.h (PC, BC, UP): New extern decls.
8587
8588 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

8609 with a FIXME (Bug#8290).
8610
8611 character.h: Rename locals to avoid shadowing.
8612 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
8613 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
8614 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
8615 (BUF_DEC_POS): Be more systematic about renaming local temporaries
8616 to avoid shadowing.

8625 Rename locals to avoid shadowing.
8626
8627 * sound.c (wav_play, au_play, Fplay_sound_internal):
8628 Fix pointer signedness.
8629 (alsa_choose_format): Remove unused local var.
8630 (wav_play): Initialize a variable to 0, to prevent undefined
8631 behavior (Bug#8278).
8632
8633 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
8634
8635 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
8636
8637 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
8638 clobbering (Bug#8298).
8639 * sysdep.c (sys_subshell): Likewise.
8640 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
8641
8642 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
8643 This should get cleaned up, so that child_setup has the
8644 same signature on all platforms.
8645
8646 * callproc.c (call_process_cleanup): Now static.
8647 (relocate_fd): Rename locals to avoid shadowing.

8649 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
8650
8651 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
8652 not to be necessary, and produces flickering.

8760 * lisp.h: ... to here, so that it can be checked.
8761

8769 (Fcall_interactively): Rename locals to avoid shadowing.
8770 Use const pointer when appropriate.
8771
8772 * lisp.h (get_system_name, get_operating_system_release):
8773 Move decls here, to check interfaces.
8774 * process.c (get_operating_system_release): Move decl to lisp.h.
8775 * xrdb.c (get_system_name): Likewise.
8776 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
8777 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
8778 some of which prompt warnings from gcc -Wbad-function-cast.
8779 (Fformat_time_string, Fencode_time, Finsert_char):
8780 (Ftranslate_region_internal, Fformat):
8781 Rename or remove local vars to avoid shadowing.

8783
8784 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
8785 avoid shadowing.
8786
8787 * lisp.h (eassert): Check that the argument compiles, even if
8788 ENABLE_CHECKING is not defined.
8789
8790 * data.c (Findirect_variable): Name an expression, to avoid
8791 gcc -Wbad-function-cast warning.

8799 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
8800 Rename locals to avoid shadowing.

8802 they're used.
8803 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

8806 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
8807 (GC_STRING_CHARS): Remove; not used.
8808 (Fmemory_limit): Cast sbrk's returned value to char *.
8809
8810 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
8811 avoids undefined behavior in theory.
8812
8813 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
8814
8815 Use functions, not macros, for up- and down-casing (Bug#8254).
8816 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8817 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
8818 to use the following functions instead of these macros.
8819 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
8820 EMACS_INT, since callers assume the returned value fits in int.
8821 (upcase1): Likewise, for UPCASE_TABLE.
8822 (uppercasep, lowercasep, upcase): New static inline functions.
8823 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

8827 Rename locals to avoid shadowing.

8829 (regex_compile, re_search_2, re_match_2_internal):
8830 Remove unused local vars.
8831 (FREE_VAR): Rewrite so as not to use empty "else",
8832 which gcc can warn about.
8833 (regex_compile, re_match_2_internal): Mark locals as initialized.
8834 (RETALLOC_IF): Define only if needed.
8835 (WORDCHAR_P): Likewise. This one is never needed, but is used
8836 only in a comment talking about a compiler bug, so put inside
8837 the #if 0 of that comment.
8838 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
8839 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
8840 Remove; unused.
8841
8842 * search.c (boyer_moore): Rename locals to avoid shadowing.

8851
8852 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
8853
8854 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
8855 All uses changed.
8856 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
8857 Rename locals to avoid shadowing.
8858 (Fvertical_motion): Mark locals as initialized.
8859
8860 * casefiddle.c (casify_object, casify_region): Now static.
8861 (casify_region): Mark local as initialized.
8862
8863 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
8864
8865 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
8866 New macros, so that the caller can use some names other than
8867 gcpro1, gcpro2, etc.
8868 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
8869 of the new macros.
8870 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
8871 argument, for consistency with GCPRO2_VAR, etc: it is now the
8872 prefix of the variable, not the variable itself. All uses
8873 changed.
8874 * dired.c (directory_files_internal, file_name_completion):
8875 Rename locals to avoid shadowing.
8876
8877 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
8878 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
8879 dired.c's scmp function, had undefined behavior.
8880 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8881 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
8882 * buffer.h: ... to here, because these macros use current_buffer,
8883 and the new implementation with inline functions needs to have
8884 current_buffer in scope now, rather than later when the macros
8885 are used.
8886 (downcase, upcase1): New static inline functions.
8887 (DOWNCASE, UPCASE1): Reimplement using these functions.
8888 This avoids undefined behavior in expressions like
8889 DOWNCASE (x) == DOWNCASE (y), which previously suffered
8890 from race conditions in accessing the global variables
8891 case_temp1 and case_temp2.
8892 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
8893 * lisp.h (case_temp1, case_temp2): Remove their decls.
8894 * character.h (ASCII_CHAR_P): Move from here ...
8895 * lisp.h: ... to here, so that the inline functions mentioned
8896 above can use them.
8897
8898 * dired.c (directory_files_internal_unwind): Now static.
8899
8900 * fileio.c (file_name_as_directory, directory_file_name):
8901 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
8902 Now static.
8903 (file_name_as_directory): Use const pointers when appropriate.
8904 (Fexpand_file_name): Likewise. In particular, newdir might
8905 point at constant storage, so make it a const pointer.
8906 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
8907 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
8908 signedness issues.
8909 (Fset_file_times, Finsert_file_contents, auto_save_error):
8910 Rename locals to avoid shadowing.

8913 (Ftry_completion, Fall_completions): Rename or remove locals
8914 to avoid shadowing.
8915
8916 * marker.c (bytepos_to_charpos): Remove; unused.
8917
8918 * lisp.h (verify_bytepos, count_markers): New decls,
8919 so that gcc does not warn that these functions aren't declared.
8920
8921 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
8922 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
8923 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
8924 (copy_text): Remove unused local var.
8925
8926 * filelock.c (within_one_second): Now static.
8927 (lock_file_1): Rename local to avoid shadowing.
8928
8929 * buffer.c (fix_overlays_before): Mark locals as initialized.
8930 (fix_start_end_in_overlays): Likewise. This function should be
8931 simplified by using pointers-to-pointers, but that's a different
8932 matter.
8933 (switch_to_buffer_1): Now static.
8934 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
8935 (report_overlay_modification): Rename locals to avoid shadowing.
8936
8937 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
8938 Fix pointer signedness issue.
8939 (sys_subshell): Mark local as volatile if checking for lint,
8940 to suppress a gcc -Wclobbered warning that does not seem to be right.
8941 (MAXPATHLEN): Define only if needed.
8942
8943 * process.c (serial_open, serial_configure): Move decls from here ...
8944 * systty.h: ... to here, so that they can be checked.
8945
8946 * fns.c (get_random, seed_random): Move extern decls from here ...
8947 * lisp.h: ... to here, so that they can be checked.
8948
8949 * sysdep.c (reset_io): Now static.
8950 (wait_for_termination_signal): Remove; unused.
8951
8952 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
8953 (copy_keymap_item, append_key, push_text_char_description):
8954 Now static.
8955 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
8956 (DENSE_TABLE_SIZE): Remove; unused.
8957 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
8958 (describe_map_tree):
8959 Rename locals to avoid shadowing.
8960
8961 * keyboard.c: Declare functions static if they are not used elsewhere.
8962 (echo_char, echo_dash, cmd_error, top_level_2):
8963 (poll_for_input, handle_async_input): Now static.
8964 (read_char, kbd_buffer_get_event, make_lispy_position):
8965 (make_lispy_event, make_lispy_movement, apply_modifiers):
8966 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

8977
8978 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
8979 (DEFINE_DUMMY_FUNCTION): New macro.
8980 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
8981 Use it.
8982 (main): Add casts to avoid warnings
8983 if GCC considers string literals to be constants.
8984
8985 * lisp.h (fatal_error_signal): Add decl, since it's exported.
8986
8987 * dbusbind.c: Pointer signedness fixes.

9108 For example, without this patch (encode-time 0 0 0 1 1
9109 1152921504606846976) returns the obviously-bogus value (-948597
9110 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
9111 reports time overflow. See
9112 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
