452
453 Fast save_excursion_save and save_excursion_restore.
454 * lisp.h (struct Lisp_Excursion): New data type.
455 (PVEC_EXCURSION): New pseudovector type.
456 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
457 to deal with it. Adjust comments.

4682012-07-26 Paul Eggert <eggert@cs.ucla.edu>
469
470 Fix export of symbols to GDB (Bug#12036).
471 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
472 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
473 emacs.c, as this is a more-suitable home. Had this been done earlier
474 the fix for 12036 would have avoided some of the problems noted in
475 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
476 would have been more obvious.
477 * emacs.c: Do not include <verify.h>; no longer needed.
478 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
479 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
480 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
481 Remove; now done in lisp.h.
482 * lisp.h (PUBLISH_TO_GDB): New macro.
483 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
484 (DATA_SEG_BITS): Use it.
485 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
486 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
487 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
488 not be usable in #if. This simplifies things.
489
4902012-07-26 Juanma Barranquero <lekktu@gmail.com>
491
492 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
493
4942012-07-26 Paul Eggert <eggert@cs.ucla.edu>

497 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
498 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
499 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
500 Adjust to changes in lisp.h and emacs.c, by using
501 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
502 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
503 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
504 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
505 instead of gdb_valbits.
506 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
507 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
508 instead of gdb_array_mark_flag.
509 (xboolvector): Get size from $->size, not $->header.size.
510 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
511 (xreload, hook-run, hookpost-run): Remove.
512 * emacs.c: Include <verify.h>.
513 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
514 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
515 Remove.
516 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
517 (gdb_USE_LSB_TAG): New enum constants.
518 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
519 Also define these as enum constants, so they're visible to GDB.
520 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
521 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
522 as constants, so they're visible to GDB.
523 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
524 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
525 Now enum constants, not macros, so they're visible to GDB.
526 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
527 more convenient now. All uses changed.
528 (VALMASK) [USE_LSB_TAG]: Also define in this case.
529 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
530

537
538 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
539 add argument, tune behavior, and adjust all callers.
540
5412012-07-25 Paul Eggert <eggert@cs.ucla.edu>
542
543 Use typedef for EMACS_INT, EMACS_UINT.
544 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
545 than macros. This simplifies debugging in the usual case, since
546 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
547 and it allows expressions involving EMACS_INT casts.
548 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
549
5502012-07-25 Jan Djärv <jan.h.d@swipnet.se>

557 * frame.c (Fredirect_frame_focus): In doc-string don't mention
558 that FOCUS-FRAME can be omitted.
559
5602012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
561
562 Adjust buffer text indirection counters at the end of Fkill_buffer.
563 * buffer.c (Fkill_buffer): Adjust indirection counters when the
564 buffer is definitely dead. This should really fix an issue reported
565 by Christoph Scholtes again. (Bug#12007).
566 (init_buffer_once): Initialize indirection counters of
567 buffer_defaults and buffer_local_symbols (for sanity and safety).
568
5692012-07-24 Eli Zaretskii <eliz@gnu.org>
570
571 * xdisp.c (init_iterator): Don't compute dimensions of truncation
572 and continuation glyphs on tooltip frames, leave them at zero.
573 Avoids continued lines in tooltips. (Bug#11832)
574
5752012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

584 or invalid. (Bug#12025)
585
586 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
587 it signals an error when a tooltip frame is being created.
588
5892012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
590
591 Cleanup miscellaneous objects allocation and initialization.

599
6002012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
601
602 Swap buffer text indirection counters in Fbuffer_swap_text.
603 * buffer.c (Fbuffer_swap_text): Swap indirections too.
604 This avoids crash reported by Christoph Scholtes at
605 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
606
6072012-07-22 Jan Djärv <jan.h.d@swipnet.se>

638
639 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

642 for the reasons.
643
644 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
645 info.dwItemData. Fixes crashes on 64-bit Windows. Suggested by

701 Adjust users accordingly.
702 * font.h (font_open_by_name): Adjust prototype.
703
7042012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

721 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
722 'for_each_per_buffer_object_at'.

772 as this interval's total length doesn't change in that case. See
773 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
774
7752012-07-18 Paul Eggert <eggert@cs.ucla.edu>
776
777 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
778 when invoking (make-bool-vector N t) and N is a positive
779 multiple of 8 -- the last 8 bits were mistakenly cleared.
780
781 Remove some struct layout assumptions in bool vectors.
782 * alloc.c (bool_header_size): New constant.
783 (header_size, word_size): Move earlier, as they're now used earlier.
784 Use 'word_size' in a few more places, where it's appropriate.
785 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
786 padding before the data member of a bool vector.
787 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
788 than doing the check by hand with an abort ().
789
7902012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
791
792 * eval.c (Fdefvar): Don't check constants since we only set the var if

1290
12912012-07-11 Glenn Morris <rgm@gnu.org>
1292
1293 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
1294 since nothing has defined it on these platforms.
1295
1296 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
1297 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

13082012-07-11 John Wiegley <johnw@newartisans.com>
1309
1310 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
1311 function attribute, so we only use it if it exists in the
1312 compiler.
1313
13142012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
1315
1316 Avoid call to strlen in fast_c_string_match_ignore_case.
1317 * search.c (fast_c_string_match_ignore_case): Change to use
1318 length argument. Adjust users accordingly.
1319 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
1320
13212012-07-11 Paul Eggert <eggert@cs.ucla.edu>

1331 * s/hpux10-20.h (HAVE_PERROR): Remove.
1332 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
1333 Remove dummy definition, as this problem was obsolete long ago.
1334
1335 Assume strerror.
1336 * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
1337
13382012-07-11 Dmitry Antipov <dmantipov@yandex.ru>

13602012-07-10 Paul Eggert <eggert@cs.ucla.edu>
1361
1362 Remove "#define unix" that is no longer needed (Bug#11905).
1363 * s/aix4-2.h (unix): Remove; no longer needed.
1364
1365 EMACS_TIME simplification (Bug#11875).
1366 This replaces macros (which typically do not work in GDB)
1367 with functions, typedefs and enums, making the code easier to debug.
1368 The functional style also makes code easier to read and maintain.
1369 * systime.h: Include <sys/time.h> on all hosts, not just if
1370 WINDOWSNT, since 'struct timeval' is needed in general.
1371 (EMACS_TIME): Now a typedef, not a macro.
1372 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1373 not macros.
1374 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
1375 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

1379 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1380 which are not functions. All uses rewritten to use:
1381 (make_emacs_time): New function.
1382 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1383 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1384 not functions. All uses rewritten to use the following, respectively:
1385 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1386 (add_emacs_time, sub_emacs_time): New functions.
1387 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1388 * fileio.c (Fcopy_file):
1389 * xterm.c (XTflash): Get the current time closer to when it's used.
1390 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
1391
1392 * bytecode.c (targets): Suppress -Woverride-init warnings.

1399 * lread.c (openp):
1400 * nsmenu.m (ns_update_menubar):
1401 * regex.c (regerror):
1402 Prefer memcpy to strncpy and strncat when either will do.
1403 * fileio.c (Fsubstitute_in_file_name):
1404 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1405 (menu_separator_name_p):
1406 * nsmenu.m (ns_update_menubar):
1407 Prefer memcmp to strncmp when either will do.
1408 * nsterm.m: Include <ftoastr.h>.
1409 (ns_get_color):
1410 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1411 Prefer snprintf to strncpy.
1412 * nsterm.m (ns_term_init):
1413 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1414 * nsterm.m (ns_term_init):
1415 Avoid the need for strncpy, by using build_string or
1416 make_unibyte_string directly. Use dtoastr, not snprintf.
1417 * process.c (Fmake_network_process): Diagnose service names that
1418 are too long, rather than silently truncating them or creating
1419 non-null-terminated names.
1420 (Fnetwork_interface_info): Likewise, for interface names.
1421 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1422 Prefer sprintf to strncat.
1423 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1424 Prefer vsnprintf to vsprintf + strncpy.
1425
14262012-07-10 Glenn Morris <rgm@gnu.org>
1427
1428 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1429 Clarify fallback case.
1430
14312012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1432
1433 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1434 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1435 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1436 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1437 where argument type is known to be a Lisp_Cons.
1438
14392012-07-10 Tom Tromey <tromey@redhat.com>
1440
1441 * bytecode.c (BYTE_CODE_THREADED): New macro.
1442 (BYTE_CODES): New macro. Replaces all old byte-code defines.
1443 (enum byte_code_op): New type.
1444 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

1446
14472012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1448
1449 Optimize pure C strings initialization.
1450 * lisp.h (make_pure_string): Fix prototype.
1451 (build_pure_c_string): New function, defined as static inline. This
1452 provides a better opportunity to optimize away calls to strlen when
1453 the function is called with compile-time constant argument.
1454 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1455 argument, adjust users accordingly. Use build_pure_c_string where
1456 appropriate.
1457 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1458 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1459 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1460
14612012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1462
1463 Avoid calls to strlen in miscellaneous functions.
1464 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1465 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1466 * lread.c (openp): Likewise.
1467
14682012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1469
1470 Avoid calls to strlen in path processing functions.
1471 * fileio.c (file_name_as_directory): Add comment. Change to add
1472 srclen argument and return the length of result. Adjust users
1473 accordingly.
1474 (directory_file_name): Fix comment. Change to add srclen argument,
1475 swap 1st and 2nd arguments to obey the common convention. Adjust
1476 users accordingly.
1477 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1478
14792012-07-10 Glenn Morris <rgm@gnu.org>
1480
1481 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1482 Move PENDING_OUTPUT_COUNT definition to configure.
1483
1484 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1485 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1486 * s/gnu.h (DATA_START): Move definitions to configure.
1487
1488 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1489 We include usg5-4-common.h, which defines them both.
1490
1491 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1492 O_RDONLY already includes it).
1493
1494 Stop ns builds setting the EMACSLOADPATH environment variable.
1495 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1496 Now it does not set EMACSLOADPATH, just returns the load-path string.
1497 * nsterm.h: Update accordingly.
1498 * lread.c [HAVE_NS]: Include nsterm.h.
1499 (init_lread) [HAVE_NS]: Use ns_load_path.
1500 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1501
15022012-07-09 Glenn Morris <rgm@gnu.org>
1503
1504 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1505 since the included bsd-common.h does so.
1506
1507 Stop ns builds setting the EMACSPATH environment variable.
1508 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1509 (ns_init_paths): Do not set EMACSPATH.
1510 * nsterm.h (ns_exec_path): Add it.
1511 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:

1513
1514 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1515
15162012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1517
1518 * process.c (wait_reading_process_output): 'waitchannels' was unset
1519 when read_kbd || !NILP (wait_for_cell); fix this.
1520
1521 Add GCC-style 'const' attribute to functions that can use it.
1522 * character.h (char_resolve_modifier_mask):
1523 * keyboard.h (make_ctrl_char):
1524 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1525 (init_character_once, next_almost_prime, init_fns, init_image)
1526 (flush_pending_output, init_sound):
1527 * mem-limits.h (start_of_data):
1528 * menu.h (finish_menu_items):
1529 Add ATTRIBUTE_CONST.
1530 * emacs.c (DEFINE_DUMMY_FUNCTION):
1531 Declare the dummy function with ATTRIBUTE_CONST.
1532 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1533 Add decls with ATTRIBUTE_CONST.
1534
1535 Minor improvements to make_formatted_string.
1536 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1537 where int is good enough, as vsprintf returns an int.
1538 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1539
15402012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1541
1542 Use make_formatted_string to avoid double length calculation.
1543 * lisp.h (make_formatted_string): New prototype.
1544 * alloc.c (make_formatted_string): New function.
1545 * buffer.c (Fgenerate_new_buffer_name): Use it.

1556 * xsettings.c (apply_xft_settings): Likewise.
1557
15582012-07-09 Glenn Morris <rgm@gnu.org>
1559
1560 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
1561 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
1562 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1563 * nsterm.h (ns_etc_directory): Add it.
1564 * callproc.c [HAVE_NS]: Include nsterm.h.
1565 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1566
15672012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1568
1569 Move marker debugging code under MARKER_DEBUG.
1570 * marker.c (MARKER_DEBUG): Move marker debugging code under
1571 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1572 for bootstrap with --enable-checking (~3x slowdown reported
1573 by Juanma Barranquero <lekktu@gmail.com>).
1574 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1575
15762012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1577
1578 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1579 See <http://bugs.gnu.org/11825#29>.
1580
15812012-07-08 Eli Zaretskii <eliz@gnu.org>
1582
1583 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1584 has no font, use the frame's font. (Bug#11813)
1585 (display_line): Add commentary about displaying truncation glyphs
1586 on GUI frames.
1587 (produce_special_glyphs): Move here from term.c.
1588
1589 * term.c (produce_special_glyphs): Move to xdisp.c.
1590
1591 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1592 section.
1593
15942012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1595
1596 * xdisp.c (display_line): Avoid warning about implicit declaration
1597 of FRAME_FONT.
1598
1599 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1600
1601 * lisp.h: Remove empty conditional.
1602
16032012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1604
1605 * lread.c (load_path_check): Now static.
1606
1607 Fix some minor --with-ns problems found by static checking.
1608 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1609 (x_set_font) [!HAVE_X_WINDOWS]:
1610 * image.c (xpm_load_image) [HAVE_NS]:
1611 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1612 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1613 Remove unused local.
1614 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1615 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1616 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1617 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1618 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1619 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1620 Fix pointer signedness problem.
1621 * xfaces.c (FRAME_X_FONT_TABLE):
1622 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1623
16242012-07-07 Glenn Morris <rgm@gnu.org>
1625
1626 * lread.c (load_path_check): New function, split from init_lread.
1627 (init_lread): Reorganize. Motivation:
1628 If EMACSLOADPATH is set, check/warn about that rather than the
1629 defaults, which we are not going to use. Hence we can remove
1630 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1631 Don't warn if site-lisp directories are missing.
1632 If not installed, start from a blank load-path, since
1633 PATH_LOADSEARCH refers to the eventual installation directories.
1634
16352012-07-07 Eli Zaretskii <eliz@gnu.org>
1636
1637 Support truncation and continuation glyphs on GUI frames, when
1638 fringes are disabled. (Bug#11832)
1639 * xdisp.c (init_iterator): Get dimensions of truncation and
1640 continuation glyphs even if on GUI frames. Adjust
1641 it->last_visible_x on GUI frames when the left or right fringes,
1642 or both, are absent.
1643 (start_display, move_it_in_display_line_to): Handle the case of a
1644 GUI frame without a fringe to display continuation or truncation
1645 glyphs.
1646 (insert_left_trunc_glyphs): Support GUI frames: make sure
1647 truncation glyphs overwrite enough glyphs from the current line to
1648 have sufficient space in pixels.
1649 (display_line): Support truncation and continuation glyphs on GUI
1650 frames. If some spare pixels are left on the line after inserting
1651 the truncation glyphs, fill that space with a stretch glyph of a
1652 suitably computed width.
1653
1654 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1655 produce_glyphs, to support GUI sessions.
1656
16572012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1658
1659 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1660
1661 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1662
1663 Do not require float-time's arg to fit in time_t (Bug#11825).
1664 This works better on hosts where time_t is unsigned, and where
1665 float-time is applied to the (negative) difference between two times.
1666 * editfns.c (decode_time_components): Last arg is now double *,
1667 not int *, and means to store all the result as a double, without
1668 worrying about whether the seconds part fits in time_t.
1669 All callers changed.
1670 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1671 All callers changed.
1672 (Ffloat_time): Do not fail merely because the specified time falls
1673 outside of time_t range.
1674
16752012-07-07 Glenn Morris <rgm@gnu.org>

1684 Update dependencies.
1685
1686 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1687
16882012-07-06 Paul Eggert <eggert@cs.ucla.edu>

1709 Eli Zaretskii <eliz@gnu.org>
1710
1711 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

1713 Obsolete settings removed.
1714
17152012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1716
1717 * process.c: Avoid unnecessary calls to gettime.
1718 (wait_reading_process_output): Don't get the time of day
1719 when gobbling data immediately and not waiting, as there's no need
1720 for it in that case. This removes a FIXME.
1721
17222012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1723
1724 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1725 is defined (Bug#11768).
1726
17272012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1728
1729 Fix marker debugging code.
1730 * marker.c (byte_char_debug_check): Do not perform the check
1731 if buffer is not multibyte.
1732 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1733 Call byte_char_debug_check with correct arguments.
1734
17352012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1736
1737 Compile marker debugging code only if ENABLE_CHECKING is defined.
1738 * marker.c (byte_char_debug_check, count_markers):
1739 Use only if ENABLE_CHECKING is defined.
1740 (byte_debug_flag): Remove.
1741 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1742 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1743
17442012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1745
1746 Avoid code repetition in marker-related functions.

17742012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1775

1777 to avoid redundant calls to unchain_overlay.
1778 * buffer.c (drop_overlay): New function.
1779 (delete_all_overlays, Fdelete_overlay): Use it.
1780 * minibuf.c (get_minibuffer): Fix comment.
1781
17822012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1783
1784 Port to OpenBSD 5.1 amd64.
1785 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1786 This is needed for OpenBSD, and should be harmless on all BSD systems.
1787 Also, include <sys/sysctl.h>, as it should be available on all
1788 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1789 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1790 use p_pid member, not kp_proc.pid.
1791
17922012-07-06 Glenn Morris <rgm@gnu.org>
1793
1794 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

1808 * xterm.c:
1809 Omit needless casts involving void * pointers and allocation.
1810 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1811 as the former is more robust if P's type is changed.
1812 Prefer xzalloc to xmalloc + memset 0.
1813 Simplify malloc-or-realloc to realloc.
1814 Don't worry about xmalloc returning a null pointer.

1822
1823 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1824 hscroll is larger than the line width. Fixes long and futile
1825 looping inside extend_face_to_end_of_line (on a TTY) producing
1826 glyphs that are not needed and thrown away.
1827
18282012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1829
1830 * marker.c (set_marker_restricted_both): Simplify by using
1831 clip_to_bounds.
1832
18332012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1834
1835 * editfns.c (region_limit): Simplify by using clip_to_bounds.

1849 (is_box_type): New function (Bug#11768).
1850 (xg_tool_item_stale_p): Call is_box_type.
1851 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1852 with default display (Bug#11768).
1853
18542012-07-05 Eli Zaretskii <eliz@gnu.org>
1855
1856 * xdisp.c (window_hscroll_limited): New function.
1857 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1858 coordinates when window's hscroll is set to insanely large
1859 values. (Bug#11857)
1860
18612012-07-05 Juanma Barranquero <lekktu@gmail.com>

1925 Problem reported by Troels Nielsen in
1926 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1927
19282012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1929
1930 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1931 This should be fixed in a better way; see Eli Zaretskii in
1932 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1933 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1934
1935 * fileio.c (time_error_value): Rename from special_mtime.
1936 The old name's problems were noted by Eli Zaretskii in
1937 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1938
1939 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1940 This variable's comment says Emacs needs at least one GDB-visible
1941 symbol of type enum pvec_type, to work around GDB problems.
1942 The symbol's value doesn't matter.
1943
1944 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1945 that causes compilation to fail on pre-C99 compilers.
1946
19472012-07-04 Juanma Barranquero <lekktu@gmail.com>
1948
1949 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1962 (PSEUDOVECTOR_SIZE_BITS): New constant.
1963 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1964 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1965 change in pvec_type.

1972 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1973 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1974 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1975 abusing vector->header.next.nbytes.
1976 (live_vector_p): Use PVEC_TYPE.
1977 (mark_object): Adapt code to extract pvectype. Use switch.
1978
19792012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1980
1981 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1982 Tighten new eassert a bit.
1983
19842012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1985
1986 Fix compilation with --enable-gcc-warnings and -O1
1987 optimization level.
1988 * doprnt.c (doprnt): Change type of tem to int, initialize
1989 to avoid compiler warning. Add eassert.
1990 * search.c (simple_search): Initialize match_byte to avoid
1991 compiler warning. Add eassert.
1992
19932012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1994
1995 Avoid weird behavior with large horizontal scrolls.
1996 Without this change, for example, large hscroll values would
1997 mess up Emacs's display on Fedora 15 x86, presumably due to
1998 overflows in int calculations in the display code.
1999 Also, if buffers had long lines, Emacs would freeze.
2000 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2001 (set_window_hscroll): New function, containing the old guts of
2002 Fset_window_hscroll. Return the clipped value.
2003 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2004 This avoids the need to check against PTRDIFF_MAX.
2005
2006 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2007
20082012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

2011
20122012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2013
2014 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2015 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2016 since GCC 4.4.6 issues a bogus warning for them.
2017
2018 Fix bugs in file timestamp newness comparisons.
2019 * fileio.c (Ffile_newer_than_file_p):
2020 * lread.c (Fload): Use full timestamp resolution of files,
2021 not just the 1-second resolution, so that files that are only
2022 slightly newer still count as newer.
2023 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2024 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2025
20262012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2027
2028 * fileio.c: Improve handling of file time marker. (Bug#11852)

2037
20382012-07-03 Glenn Morris <rgm@gnu.org>
2039
2040 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2041 and did not make it into globals.h).
2042
20432012-07-03 Tom Tromey <tromey@redhat.com>

2089 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2090 values which aren't power of 2.
2091 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2092 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2093 accordingly.
2094
20952012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2096
2097 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2098
2099 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2100
21012012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2102
2103 * alloc.c (allocate_vector_block): Remove redundant
2104 calls to mallopt if DOUG_LEA_MALLOC is defined.
2105 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2106 avoid calls to mallopt if zero_vector is returned.
2107
21082012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2109
2110 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2111 is enabled, avoid dereferencing NULL current_sblock if
2112 running undumped.
2113

2115
2116 Cleanup basic buffer management.
2117 * buffer.h (struct buffer): Change layout to use generic vector
2118 marking code. Fix some comments. Change type of 'clip_changed'
2119 to bitfield. Remove unused #ifndef old.
2120 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2121 (GET_OVERLAYS_AT): Fix indentation.
2122 (for_each_per_buffer_object_at): New macro.
2123 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2124 (Fbuffer_local_variables): Use it.
2125 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2126 * alloc.c (allocate_buffer): Adjust to match new layout of
2127 struct buffer. Fix comment.
2128 (mark_overlay): New function.

2132 and related comments.
2133
21342012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2135
2136 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2137 wrapper that is not needed because the wrapped code is a no-op (zero
2138 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2139 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2140
21412012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2142
2143 * alloc.c (mark_buffer): Simplify. Remove prototype.
2144 (mark_object): Add comment. Reorganize marking of vector-like
2145 objects. Use CHECK_LIVE for all vector-like objects except buffers
2146 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2147 redundant calls to mark_vectorlike for bool vectors.
2148
21492012-06-30 Glenn Morris <rgm@gnu.org>
2150
2151 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2152
2153 * epaths.in (PATH_SITELOADSEARCH): New.
2154 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2155 This is rather than relying on --enable-locallisppath elements
2156 having "site-lisp" in their names. (Bug#10208#25, 11658)
2157
21582012-06-30 Eli Zaretskii <eliz@gnu.org>
2159
2160 * w32proc.c (sys_select): Accept and ignore one more argument.
2161
2162 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2163
2164 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2165 (pselect) [!MS_DOS]: Redirect to sys_select.
2166
2167 * sysdep.c: Don't include dos.h and dosfns.h.
2168
2169 * process.c (sys_select):
2170 * msdos.c (sys_select): Accept one more argument and ignore it.
2171
2172 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2173 adapt data types and code to that.
2174
2175 * dosfns.c:
2176 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2177 which clashes with the gnulib function of the same name.
2178
21792012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2180
2181 * font.c (font_style_to_value, font_style_symbolic)
2182 (font_prop_validate_style): Add type checks for values in
2183 font_style_table.
2184
2185 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2186 argument.
2187 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2188 uses.
2189
21902012-06-29 Eli Zaretskii <eliz@gnu.org>
2191
2192 * xdisp.c (try_window_id): Undo last change.
2193
2194 * w32.c (getwd): Adjust commentary about startup_dir.
2195 (init_environment): Always call sys_access, even in non-MSVC
2196 builds. Don't chdir to the directory of the Emacs executable.
2197 This undoes code from 1997 which was justified by the need to
2198 "avoid conflicts when removing and renaming directories". But its
2199 downside was that every relative file name was being interpreted
2200 relative to the directory of the Emacs executable, which can never
2201 be TRT. In particular, it broke sys_access when called with
2202 relative file names.
2203 (sys_access): Map GetLastError to errno.
2204
22052012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2206

2208 to bitfield. Fix comment. Adjust users accordingly.
2209 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2210 Adjust comment.
2211 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2212 to ptrdiff_t.
2213
22142012-06-29 Andreas Schwab <schwab@linux-m68k.org>

2229 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2230 undefined. Convert from xassert to eassert.
2231 * nsmenu.m: Convert from xassert to eassert.
2232 * nsterm.m: Likewise.

22382012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2239
2240 Avoid integer overflow on scroll-left and scroll-right.
2241 * window.c (HSCROLL_MAX): New macro.

2243 overflow when requested scroll falls outside ptrdiff_t range.
2244
22452012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2246
2247 * window.h (struct window): Change type of 'hscroll',
2248 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2249 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2250 Adjust users accordingly.
2251 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2252 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2253 from EMACS_INT to ptrdiff_t.

2272 enabled with --enable-checking=[all,glyphs] configure option.
2273 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2274 adjust comments accordingly.

2367
23682012-06-26 Dmitry Antipov <dmantipov@yandex.ru>

2386
2387 * alloc.c: Remove build_string.
2388 * lisp.h: Define build_string as static inline. This provides

2396
2397 Use sprintf return value instead of invoking strlen on result.
2398 In the old days this wasn't portable, since some sprintf
2399 implementations returned char *. But they died out years ago and
2400 Emacs already assumes sprintf returns int.
2401 Similarly for float_to_string.
2402 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2403 * ccl.c (ccl_driver):

2410 Use sprintf or float_to_string result to avoid need to call strlen.
2411 * data.c (Fnumber_to_string):
2412 Use make_unibyte_string, since the string must be ASCII.
2413 * lisp.h, print.c (float_to_string): Now returns int length.
2414 * term.c (produce_glyphless_glyph):
2415 Use sprintf result rather than recomputing it.
2416
2417 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2418 * Makefile.in (ALL_CFLAGS):

2442
2443 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2444 sprintf already null-terminates its output.
2445
2446 * xfns.c (x_window): Remove redundant cast.
2447
24482012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2449
2450 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2454
2455 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2456 instead of truncating it to 63 (admittedly a generous limit).

2516 * keyboard.c (kbd_buffer_get_event):
2517 * process.c (Faccept_process_output):

2540 Privately reported by Herbert J. Skuhra.
2541 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2542 All uses changed.
2543 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2544 not make_lisp_timeval, when the argument is of type EMACS_TIME.

2552 language ID in the event parameters.
2553
2554 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2555 event.code, not the obscure "character set ID".
2556
25572012-06-23 Chong Yidong <cyd@gnu.org>
2558
2559 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2560

2562
2563 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

25862012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2587
2588 Support higher-resolution time stamps (Bug#9000).
2589 The time stamps are only nanosecond-resolution at the C level,
2590 since that's the best that any real-world system supports now.
2591 But they are picosecond-resolution at the Lisp level, as that's
2592 easy, and leaves room for future OS improvements.
2593
2594 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2595 (LIBES): Use it.
2596
2597 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2598 Don't get current time unless it's needed.
2599
2600 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2601 now provides it if it's absent.
2602 (start_atimer): Port to higher-res time stamps.
2603 Check for time stamp overflow. Don't get current time more
2604 often than is needed.
2605
2606 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2607 Include systime.h, not time.h.
2608 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2609
2610 * dired.c: Include stat-time.h.
2611 (Ffile-attributes): File times now have higher resolution.
2612
2613 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2614 (struct image): Timestamp now has higher resolution.
2615
2616 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2617 has at least microseconds now. All uses removed.
2618 (update_frame, update_single_window, update_window, update_frame_1)
2619 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2620
2621 * editfns.c (time_overflow): Now extern.
2622 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2623 (float-time, Fformat_time_string, Fcurrent_time_string)
2624 (Fcurrent_time_zone): Accept and generate higher-resolution
2625 time stamps.
2626 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2627 (decode_time_components, lisp_seconds_argument): New functions.
2628 (make_time): Now static.
2629 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2630 Report an error if the time is invalid, rather than having the caller
2631 do that.
2632
2633 * fileio.c: Include <stat-time.h>
2634 (Fcopy_file): Copy higher-resolution time stamps.
2635 Prefer to set the time stamp via a file descriptor if that works.
2636 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2637 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2638 (Fvisited_file_modtime, Fset_visited_file_modtime):
2639 Support higher-resolution time stamps.
2640
2641 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2642
2643 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2644
2645 * image.c (prepare_image_for_display, clear_image_cache)
2646 (lookup_image): Port to higer-resolution time stamps.
2647
2648 * keyboard.c (start_polling, bind_polling_period):
2649 Check for time stamp overflow.
2650 (read_char, kbd_buffer_get_event, timer_start_idle)
2651 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2652 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2653 Port to higher-resolution time stamps. Do not assume time_t is signed.
2654 (decode_timer): New function. Timers are now vectors of length 9,
2655 not 8, to accommodate the picosecond component.
2656 (timer_check_2): Use it.
2657
2658 * nsterm.m (select_timeout, timeval_subtract): Remove.
2659 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2660 as they're a bit more accurate and handle overflow better.
2661 (ns_select): Change prototype to be compatible with pselect.
2662 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2663 * nsterm.h (ns_select): Adjust prototype.
2664
2665 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2666 us-resolution time stamps.
2667 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2668
2669 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2670
2671 * lisp.h (time_overflow): New decl.
2672 (wait_reading_process_output): First arg is now intmax_t, not int,
2673 to accommodate larger waits.
2674
2675 * process.h (struct Lisp_Process.read_output_delay):
2676 Now counts nanoseconds, not microseconds.
2677 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2678 EMACS_HAS_USECS.
2679 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2680 (wait_reading_process_output):
2681 Port to ns-resolution time stamps.
2682 (Faccept_process_output, wait_reading_process_output):
2683 Check for time stamp overflow. Do not assume time_t is signed.
2684 (select_wrapper): Remove; we now use pselect.
2685 (Fprocess_attributes): Now generates ns-resolution time stamps.
2686
2687 * sysdep.c: Include utimens.h. Don't include utime.h
2688 or worry about struct utimbuf; gnulib does that for us now.
2689 (gettimeofday): Remove; gnulib provides a substitute.
2690 (make_timeval): New function.
2691 (set_file_times): Now sets ns-resolution time stamps.
2692 New arg FD; all uses changed.
2693 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2694 (system_process_attributes):
2695 Now returns ns-resolution time stamp. All uses changed.
2696 Check for time stamp overflow.
2697
2698 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2699 provides a substitute now.
2700
2701 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2702 since it guarantees struct timespec.
2703 (EMACS_TIME): Now struct timespec, so that we can support
2704 ns-resolution time stamps.
2705 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2706 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2707 (EMACS_USECS): Remove.
2708 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2709 so multiply the arg by 1000 before storing it.
2710 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2711 New macros.
2712 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2713 Port to ns-resolution time stamps.
2714 (EMACS_TIME_NEG_P): Remove; replaced by....

2719 (make_timeval, make_lisp_time, decode_time_components): New decls.
2720 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2721 that it mishandled time_t overflow. You can't compare by subtracting!
2722 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2723 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2724
2725 * term.c: Include <sys/time.h>.
2726 (timeval_to_Time): New function, for proper overflow wraparound.
2727 (term_mouse_position, term_mouse_click): Use it.
2728
2729 * undo.c (record_first_change): Support higher-resolution time stamps
2730 in the undo buffer.
2731 (Fprimitive_undo): Use them when restoring time stamps.
2732
2733 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2734 (w32_get_internal_run_time):
2735 Port to higher-resolution Emacs time stamps.
2736 (ltime): Now accepts single 64-bit integer, as that's more convenient
2737 for callers.
2738
2739 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2740
2741 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2742 for compatibility with pselect. Support ns-resolution time stamps.
2743
2744 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2745
2746 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2747 Check for time stamp overflow, and support ns-resolution time stamps.
2748
2749 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2750 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2751 (timeval_subtract): Remove; no longer needed.
2752 (XTflash, XTring_bell, x_wait_for_event):
2753 Port to ns-resolution time stamps. Don't assume time_t is signed.
2754

27592012-06-22 Eli Zaretskii <eliz@gnu.org>
2760
2761 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2762 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2763 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2764 staticidx goes up to 1597 out of 1600 = 0x640.)
2765
27662012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2767
2768 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2769 Otherwise, the umask might be mistakenly 0 while handling input signals.

2778 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
2779 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2780 access to `contents' member of Lisp_Vector objects with AREF and ASET
2781 where appropriate.
2782

2792 Callers changed.
2793 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2794 since tty frames can be explicitly named.
2795 (prepare_menu_bars): Likewise.
2796
2797 * term.c (Ftty_top_frame): New function.
2798
27992012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2800
2801 Port byte-code-meter to modern targets.
2802 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2803 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2804 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2805 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2806 (METER_1, METER_2): Simplify.
2807
28082012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2809
2810 * data.c (Fdefalias): Return `symbol' (bug#11686).
2811
28122012-06-18 Martin Rudalics <rudalics@gmx.at>
2813
2814 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2815 gets killed during executing of this function (Bug#11665).
2816 Try to always return Qt when the buffer has been actually killed.
2817 (Vkill_buffer_query_functions): In doc-string say that functions
2818 run by this hook should not change the current buffer.
2819
28202012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2821
2822 Fix recently-introduced process.c problems found by static checking.

28402012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2841
2842 * lisp.h (eassert): Assume C89 or later.
2843 This removes the need for CHECK.
2844 (CHECK): Remove. Its comments about always evaluating its
2845 argument were confusing, as 'eassert' typically does not evaluate
2846 its argument.
2847
2848 * coding.c (produce_chars): Use ptrdiff_t, not int.
2849
2850 * xterm.c (x_draw_underwave): Check for integer overflow.

2973 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
2974 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
2975 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
2976 (INTTYPEBITS): New macro, for clarity.
2977 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
2978 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

2980 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
2981 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

2995 instead of union.
2996 (XLI, XIL): Define.
2997 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
2998 Use them.
2999 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
3000 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
3001 * alloc.c (widen_to_Lisp_Object): Remove.
3002 (mark_memory): Use XIL instead of widen_to_Lisp_Object.
3003 * frame.c (delete_frame): Remove outdated comment.
3004 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
3005 USE_LISP_UNION_TYPE.

3024 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3025 * alloc.c (make_number) [!defined make_number]:

3028 (roundup_size): Verify that it is a power of 2.
3029 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3030 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3031 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
3032 -DUSE_LSB_TAG=0, to override the automatically-selected default.
3033 USE_LSB_TAG now is always defined to be either 0 or 1.
3034 All uses changed.
3035 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3036 code works fine either way, and efficiency is not a concern here,
3037 as the union type is for debugging, not for production.
3038 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3039 Use an inline function on all platforms when using the union type,
3040 since this is simpler and 'static inline' can be used portably

3126 * xdisp.c (vmessage): Treat frame message as multibyte.
3127 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3128 would generate the diagnostic "Making \302\247 buffer-local while
3129 let-bound!".
3130
31312012-06-08 Eli Zaretskii <eliz@gnu.org>
3132
3133 * dispnew.c (showing_window_margins_p): Undo last change, which
3134 was done due to an inadvertent commit.

3183
3184 * doprnt.c (doprnt): Truncate multibyte char correctly.
3185 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3186 would mishandle a string argument "Xc" if X was a multibyte
3187 character of length 2: it would truncate after X's first byte
3188 rather than including all of X.
3189
31902012-06-06 Chong Yidong <cyd@gnu.org>
3191

3238
3239 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3240
3241 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3242 Convert pctcpu and pctmem to Lisp float properly.

3246
3247 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

3253
32542012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3255
3256 For a 'struct window', replace some Lisp_Object fields to
3257 bitfields where appropriate, remove unused fields.
3258 * window.h (struct window): Remove unused 'last_mark_x' and
3259 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3260 change it's type from Lisp_Object to bitfield.
3261 Change type of 'force_start', 'optional_new_start',
3262 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3263 fields from Lisp_Object to bitfield. Adjust users accordingly.
3264
32652012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3266
3267 Pacify gcc -Wdouble-precision when using Xaw.

3271 and 'double' in a couple of places.
3272
32732012-05-31 Eli Zaretskii <eliz@gnu.org>
3274
3275 * xdisp.c (handle_stop): Detect whether we have overlay strings
3276 loaded by testing it->current.overlay_string_index to be
3277 non-negative, instead of checking whether n_overlay_strings is
3278 positive. (Bug#11587)
3279

3287
3288 * search.c (search_buffer): Remove calls to
3289 r_alloc_inhibit_buffer_relocation, as it is now called by
3290 maybe_unify_char, which was the cause of relocation of buffer text
3291 in bug#11519.
3292
32932012-05-31 Eli Zaretskii <eliz@gnu.org>
3294
3295 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3296 for the duration of call to load_charset, to avoid problems with

3298 pointers.
3299
3300 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3301 decrement the inhibition flag, instead of just setting or

3324 (safe_bcopy): Remove decl; no longer has that name.
3325 (main): Coalesce #if into single bit of code, for simplicity.
3326 Cast pointers to uintptr_t, since standard libraries want integers

3358 be moved to is live and rearrange lines to make sure that errors
3359 will not put the overlay in an inconsistent state.
3360 (Fdelete_overlay): Cosmetics.
3361

3379 This avoids undefined behavior that might cause the eassert
3380 to not catch an out-of-range value.
3381
33822012-05-28 Juanma Barranquero <lekktu@gmail.com>
3383
3384 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

33872012-05-27 Eli Zaretskii <eliz@gnu.org>
3388
3389 * bidi.c (bidi_mirror_char): Fix last change.
3390
33912012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3392
3393 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3394 when referring to sectname field in printf format.
3395
33962012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3397
3398 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3399 Only r_alloc_inhibit_buffer_relocation needed to be added;
3400 the others were already declared.
3401
3402 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3403 before checking whether it's out of range. Put the check inside
3404 eassert. See
3405 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3406
34072012-05-27 Ken Brown <kbrown@cornell.edu>
3408
3409 * callproc.c (Fcall_process): Restore a line that was accidentally
3410 commented out in the 2011-02-13 change (bug#11547).
3411
34122012-05-27 Eli Zaretskii <eliz@gnu.org>
3413
3414 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3415 defined on ralloc.c.
3416
3417 * buffer.c [REL_ALLOC]: Remove prototypes of
3418 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3419 they are now on lisp.h.
3420
3421 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3422
3423 * search.c (search_buffer): Use it to inhibit relocation of buffer
3424 text while re_search_2 is doing its job, because re_search_2 is
3425 passed C pointers to buffer text. (Bug#11519)
3426
3427 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3428 Update value to 24.
3429
3430 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3431 state after an additional call to move_it_in_display_line_to, keep
3432 the values of it->max_ascent and it->max_descent found for the
3433 entire line.
3434 (pos_visible_p): Revert the comparison against bottom_y to what it
3435 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3436 (Bug#11464)
3437
34382012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3439
3440 Fix coding-related core dumps with gcc -ftrapv.
3441 The code was computing A - B, where A and B are pointers, and B is
3442 random garbage. This can lead to core dumps on platforms that
3443 have special pointer registers, and it also leads to core dumps on
3444 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3445 A - B only when B is initialized properly.
3446 * coding.c (coding_set_source, coding_set_destination): Return void.
3447 (coding_change_source, coding_change_destinations): New functions,
3448 with the old behaviors of coding_set_source and coding_set_destination.
3449 All callers that need an offset changed to use these new functions.
3450
34512012-05-26 Glenn Morris <rgm@gnu.org>
3452
3453 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3454
34552012-05-26 Eli Zaretskii <eliz@gnu.org>
3456
3457 Extend mouse support on W32 text-mode console.
3458 * xdisp.c (draw_row_with_mouse_face):
3459 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3460
3461 * w32console.c: Include window.h.
3462 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3463 New functions.
3464 (initialize_w32_display): Initialize mouse-highlight data.
3465
3466 * w32inevt.c: Include termchar.h and window.h.
3467 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3468 moves, call note_mouse_highlight. If help_echo changed, call
3469 gen_help_event to produce help-echo message in the echo area.
3470 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3471 highlight info.
3472
34732012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3474
3475 * lread.c (read1): Simplify slightly to avoid an overflow warning
3476 with GCC 4.7.0 on x86-64.
3477
34782012-05-26 Eli Zaretskii <eliz@gnu.org>
3479
3480 * bidi.c (bidi_mirror_char): Revert last change: an int is
3481 definitely wide enough here.
3482
34832012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3484
3485 Fix integer width and related bugs (Bug#9874).

3487 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3488 (string_bytes, check_sblock, allocate_string_data):

3493 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3494 (mark_vectorlike):
3495 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3496 (allocate_pseudovector):
3497 Use int, not EMACS_INT, where int is wide enough.
3498 (inhibit_garbage_collection, Fgarbage_collect):
3499 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3500 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3501 int might not be wide enough.
3502 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3503 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

3505 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3506 (bidi_level_of_next_char, bidi_move_to_visually_next):
3507 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3508 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3509 (Fkill_buffer, Fset_buffer_major_mode)
3510 (advance_to_char_boundary, Fbuffer_swap_text)
3511 (Fset_buffer_multibyte, overlays_at, overlays_in)
3512 (overlay_touches_p, struct sortvec, record_overlay_string)
3513 (overlay_strings, recenter_overlay_lists)

3516 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3517 (Foverlay_recenter, last_overlay_modification_hooks_used)
3518 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3519 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3520 (validate_region): Omit unnecessary test for b <= e,
3521 since that's guaranteed by the previous test.
3522 (adjust_overlays_for_delete): Avoid pos + length overflow.
3523 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3524 (report_overlay_modification):
3525 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3526 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3527 Omit pointer cast, which isn't needed anyway, and doesn't work
3528 after the EMACS_INT -> ptrdiff_t change.
3529 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3530 * buffer.h: Adjust decls to match defn changes elsewhere.
3531 (struct buffer_text, struct buffer):
3532 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3533 Use EMACS_INT, not int, where int might not be wide enough.
3534 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3535 not int, to avoid needless 32-bit limit on 64-bit hosts.
3536 (exec_byte_code): Use tighter memory-full test, one that checks
3537 for alloca overflow. Don't compute the address of the object just
3538 before an array, as that's not portable. Use EMACS_INT, not
3539 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3540 * callint.c (Fcall_interactively):
3541 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3542 * callproc.c (call_process_kill, Fcall_process):
3543 Don't assume pid_t fits into an Emacs fixnum.
3544 (call_process_cleanup, Fcall_process, child_setup):

3552 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3553 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3554 (casify_object): Avoid integer overflow when overallocating buffer.
3555 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3556 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3557 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3558 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3559 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3560 integers are now checked earlier. All uses replaced with XINT.
3561 (ccl_driver):
3562 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3563 For CCL_MapSingle, check that content and value are in int range.
3564 (ccl_driver, Fregister_code_conversion_map):
3565 Check that Vcode_version_map_vector is a vector.
3566 (resolve_symbol_ccl_program): Check that vector header is in range.
3567 Always copy the vector, so that we can check its contents reliably
3568 now rather than having to recheck each instruction as it's being
3569 executed. Check that vector words fit in 'int'.
3570 (ccl_get_compiled_code, Fregister_ccl_program)
3571 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3572 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3573 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3574 contents are in range.
3575 (Fccl_execute_on_string): Check that status is in range.
3576 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3577 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3578 Accept and return EMACS_INT, not int, because callers can pass values
3579 out of 'int' range.
3580 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3581 (multibyte_chars_in_text, parse_str_as_multibyte)

3583 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3584 (string_escape_byte8, Fget_byte):
3585 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3586 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3587 avoid mishandling large integers.
3588 * character.h: Adjust decls to match defn changes elsewhere.
3589 * charset.c (load_charset_map_from_file, find_charsets_in_text)
3590 (Ffind_charset_region):

3592 (load_charset_map_from_file): Redo idx calculation to avoid overflow.

3594 Don't assume fixnum fits in int.
3595 (load_charset_map_from_vector, Fmap_charset_chars):
3596 Remove now-unnecessary CHECK_NATNUMs.
3597 (Fdefine_charset_internal): Check ranges here, more carefully.
3598 Don't rely on undefined behavior with signed left shift overflow.
3599 Don't assume unsigned int fits into fixnum, or that fixnum fits
3600 into unsigned int. Don't require max_code to be a valid fixnum;
3601 that's not true for gb10830 4-byte on a 32-bit host. Allow
3602 invalid_code to be a cons, for the same reason. Require code_offset
3603 to be a character. Avoid int overflow if max_char is close
3604 to INT_MAX.
3605 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3606 this is intended anyway and avoids some undefined behavior.
3607 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3608 INDEX_TO_CODE_POINT, as that's what it expects.
3609 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3610 * charset.h (DECODE_CHAR): Return int, not unsigned;
3611 this is what was intended anyway, and it avoids undefined behavior.
3612 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3613 integer-overflow issues.
3614 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3615 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3616 where the argument is EMACS_INT, and this behavior is not intended.
3617 * chartab.c (Fmake_char_table, Fset_char_table_range)
3618 (uniprop_get_decoder, uniprop_get_encoder):
3619 Don't assume fixnum fits in int.
3620 * cmds.c (move_point): New function, that does the gist of
3621 Fforward_char and Fbackward_char, but does so while checking
3622 for integer overflow more accurately.
3623 (Fforward_char, Fbackward_char): Use it.
3624 (Fforward_line, Fend_of_line, internal_self_insert)
3625 (internal_self_insert):
3626 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3627 Fix a FIXME, by checking for integer overflow when calculating
3628 target_clm and actual_clm.

3663 Don't access memory outside of the args array.
3664 (Fdefine_coding_system_internal): Check for charset-id overflow.
3665 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
3666 result of ENCODE_CHAR.

3684 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3685 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
3686 Do not attempt to compute the address of the object just before a
3687 buffer; this is not portable.
3688 (Faref, Faset):
3689 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3690 (Faset): Use int, not EMACS_INT, where int is wide enough.

4417 (report_error, report_error_1, make_hdr, copy_sym)
4418 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4419 Make arguments const char *, not char *, to avoid violations of C

4421
44222012-05-14 Eli Zaretskii <eliz@gnu.org>
4423
4424 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4425 already have overlays loaded.
4426 (handle_single_display_spec): Before returning without displaying
4427 fringe bitmap, synchronize the bidi iterator with the main display
4428 iterator, by calling iterate_out_of_display_property.
4429 (iterate_out_of_display_property): Detect buffer iteration by
4430 testing that it->string is a Lisp string.
4431 (get_next_display_element): When the current object is exhausted,
4432 and there's something on it->stack, call set_iterator_to_next to
4433 proceed with what's on the stack, instead of returning zero.
4434 (set_iterator_to_next): If called at the end of a Lisp string,
4435 proceed to consider_string_end without incrementing string
4436 position. Don't increment display vector index past the end of
4437 the display vector. (Bug#11417)
4438 (pos_visible_p): Don't report a position visible when move_it_to
4439 stopped at the last line of window, which happens to be scanned
4440 backwards by the bidi iteration. (Bug#11464)
4441
44422012-05-14 Eli Zaretskii <eliz@gnu.org>
4443
4444 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4445 and right-margin display specs even if the spec is invalid or we
4446 are on a TTY, and thus unable to display on the fringes.
4447 That's because the text with the property will not be displayed anyway,
4448 so we need to signal to the caller that this is a "replacing"
4449 display spec. This fixes display when the spec is invalid or we
4450 are on a TTY.

44522012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4453
4454 * unexaix.c (make_hdr): Fix typo in prototype.
4455 This bug broke the build on AIX. Problem reported by Gilles Pion.
4456
44572012-05-14 Michael Albinus <michael.albinus@gmx.de>
4458
4459 * keyboard.c (kbd_buffer_get_event): Read special events also in
4460 batch mode. (Bug#11415)
4461
44622012-05-12 Glenn Morris <rgm@gnu.org>
4463
4464 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4465
44662012-05-12 Eli Zaretskii <eliz@gnu.org>
4467
4468 * lisp.mk (lisp): Add newcomment.elc.
4469
44702012-05-12 Glenn Morris <rgm@gnu.org>
4471
4472 * Makefile.in (MKDIR_P): New, set by configure.
4473 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4474
44752012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4476
4477 Remove unused function hourglass_started.
4478 * dispextern.h (hourglass_started):
4479 * w32fns.c (hourglass_started):
4480 * xdisp.c (hourglass_started): Remove.
4481
44822012-05-10 Juanma Barranquero <lekktu@gmail.com>
4483
4484 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4485 Update dependencies.
4486
44872012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4488
4489 * xgselect.c (xg_select): Put maxfds+1 into a var.
4490 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4491
4492 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4493
44942012-05-10 Dave Abrahams <dave@boostpro.com>
4495
4496 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4497 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4498
44992012-05-09 Michael Albinus <michael.albinus@gmx.de>
4500
4501 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4502 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4503 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4504 Initialize xd_registered_buses.
4505
45062012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4507
4508 Untag more efficiently if USE_LSB_TAG.
4509 This is based on a proposal by YAMAMOTO Mitsuharu in
4510 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4511 For an admittedly artificial (nth 8000 longlist) benchmark on
4512 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4513 Emacs's overall text size by 1%.
4514 * lisp.h (XUNTAG): New macro.
4515 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4516 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4517 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4518 * eval.c (Fautoload):
4519 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4520 * frame.h (XFRAME): Use XUNTAG.
4521
4522 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4523 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4524 Remove unportable assumptions about print widths of types like
4525 dbus_uint32_t.
4526 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4527 intptr_t when converting between pointer and integer, to avoid GCC
4528 warnings about wrong width.
4529
45302012-05-09 Eli Zaretskii <eliz@gnu.org>
4531
4532 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4533 stack for each reader_thread, instead of defaulting to 8MB
4534 determined by the linker. This avoids failures in creating
4535 subprocesses on Windows 7, see the discussion in this thread:
4536 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4537
45382012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4539
4540 Fix up display of the *Minibuf-0* buffer in the mini window.
4541 * keyboard.c (read_char): Don't clear the echo area if there's no
4542 message to clear.
4543 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4544 contents of *Minibuf-0*) if there's no message displayed in its stead.
4545
45462012-05-07 Michael Albinus <michael.albinus@gmx.de>
4547
4548 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4549 batch mode.
4550
45512012-05-06 Chong Yidong <cyd@gnu.org>
4552
4553 * lisp.mk (lisp): Update.
4554
45552012-05-05 Jim Meyering <meyering@redhat.com>
4556
4557 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4558
45592012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4560
4561 * data.c (PUT_ERROR): New macro.
4562 (syms_of_data): Use it. Add new error type `user-error'.
4563 * undo.c (user_error): New function.
4564 (Fprimitive_undo): Use it.
4565 * print.c (print_error_message): Adjust print style for `user-error'.
4566 * keyboard.c (user_error): New function.
4567 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4568
45692012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4570
4571 Do not limit current-time-string to years 1000..9999.
4572 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4573 (Fcurrent_time_string): Support any year that is supported by the
4574 underlying localtime representation. Don't use asctime, as it
4575 has undefined behavior for years outside the range -999..9999.
4576
45772012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4578
4579 Fix race conditions involving setenv, gmtime, localtime, asctime.
4580 Without this fix, interrupts could mess up code that uses these
4581 nonreentrant functions, since setting TZ invalidates existing
4582 tm_zone or tzname values, and since most of these functions return
4583 pointers to static storage.
4584 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4585 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4586 Grow the critical sections to include not just invoking
4587 localtime/gmtime, but also accessing these functions' results
4588 including their tm_zone values if any, and any related TZ setting.
4589 (format_time_string): Last arg is now struct tm *, not struct tm **,
4590 so that the struct tm is saved in the critical section.
4591 All callers changed. Simplify allocation of initial buffer, partly
4592 motivated by the fact that memory allocation needs to be outside
4593 the critical section.
4594
45952012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4596
4597 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4598 with RESET_INTERVAL.
4599
4600 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4601 Remove duplicated buffer name initialization.
4602
46032012-05-02 Jim Meyering <jim@meyering.net>
4604
4605 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4606
4607 * xfns.c (x_window): Use xstrdup (Bug#11375).
4608
46092012-05-02 Eli Zaretskii <eliz@gnu.org>
4610
4611 * xdisp.c (pos_visible_p): If already at a newline from the
4612 display string before the 'while' loop, don't walk back the glyphs
4613 from it3.glyph_row. Solves assertion violation when the display
4614 string begins with a newline (egg.el). (Bug#11367)
4615
46162012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4617
4618 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4619 Move to simple.el.
4620
46212012-05-01 Glenn Morris <rgm@gnu.org>
4622
4623 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4624 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4625 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4626 All were removed before 23.1.
4627
4628 * dispnew.c: Remove HAVE_LIBNCURSES test;
4629 it is always true on relevant platforms.
4630
4631 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4632 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4633
4634 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4635
46362012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4637
4638 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4639 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4640 Remove.
4641
46422012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4643
4644 Do not avoid creating empty evaporating overlays (Bug#9642).
4645 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4646 That is, do not delete an evaporating overlay if it becomes
4647 empty after its bounds are adjusted to fit within its buffer.
4648 This fix caused other problems, and I'm reverting it until we get
4649 to the bottom of them.
4650
46512012-04-27 Chong Yidong <cyd@gnu.org>
4652
4653 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4654
46552012-04-27 Eli Zaretskii <eliz@gnu.org>
4656
4657 * xdisp.c (pos_visible_p): If the window start position is beyond
4658 ZV, start the display from buffer beginning. Prevents assertion
4659 violation in init_iterator when the minibuffer window is scrolled
4660 via the scroll bar.
4661
4662 * window.c (window_scroll_pixel_based): Likewise.
4663
46642012-04-27 Chong Yidong <cyd@gnu.org>
4665
4666 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4667
46682012-04-27 Glenn Morris <rgm@gnu.org>
4669

4672
46732012-04-27 Eli Zaretskii <eliz@gnu.org>
4674
4675 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4676 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4677
46782012-04-26 Eli Zaretskii <eliz@gnu.org>
4679
4680 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4681 display element, check also the underlying string or buffer
4682 character. (Bug#11341)
4683
4684 * w32menu.c: Include w32heap.h.
4685 (add_menu_item): If the call to AppendMenuW (via
4686 unicode_append_menu) fails, disable Unicode menus only if we are
4687 running on Windows 9X/Me.
4688
46892012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4690

4692 (xgetint): Add missing shift for LSB tags.
4693
46942012-04-24 Martin Rudalics <rudalics@gmx.at>
4695
4696 * keyboard.c (read_char): Don't wipe echo area for select window
4697 events: These might get delayed via `mouse-autoselect-window'
4698 (Bug#11304).
4699
47002012-04-24 Juanma Barranquero <lekktu@gmail.com>
4701

4706
4707 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4708 now a cons (bug#11311).
4709
47102012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4711
4712 Do not create empty overlays with the evaporate property (Bug#9642).
4713 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4714 if it becomes empty after its bounds are adjusted to fit within
4715 its buffer. Without this fix, in a nonempty buffer (let ((o
4716 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4717 yields an empty overlay that has the evaporate property, which is
4718 not supposed to happen.
4719
4720 Fix minor GTK3 problems found by static checking.
4721 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4722 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4723 (struct _EmacsFixedClass, emacs_fixed_get_type):

4726 (emacs_fixed_class_init): Omit unused local.
4727 (emacs_fixed_child_type): Remove; unused.

4730 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4731 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4732 (EMACS_FIXED_GET_CLASS): Remove; unused.
4733 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4734

4736 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4737
47382012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4739
4740 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4741 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4742 (__malloc_size_t, __malloc_ptrdiff_t):
4743 Remove. All uses removed, replaced by the definiens if needed,
4744 since we can assume C89 or better now.
4745 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4746 (protect_malloc_state, align, get_contiguous_space)
4747 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4819
4820 * alloc.c: Handle unusual debugging option combinations.
4821 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4822 since the two debugging options are incompatible.
4823 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4824 is defined.
4825 (mem_init, mem_insert, mem_insert_fixup):

4834
4835 * sysdep.c [__FreeBSD__]: Minor cleanups.
4836 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4837 Use Emacs indenting style more consistently. Avoid some casts.

4850
4851 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
4852 It is never used otherwise.

48612012-04-20 Chong Yidong <cyd@gnu.org>
4862
4863 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4864 set the status to "failed" and ensure that sentinel is run.
4865
48662012-04-20 Glenn Morris <rgm@gnu.org>
4867
4868 * process.c (Fset_process_inherit_coding_system_flag)

4871
48722012-04-20 Eli Zaretskii <eliz@gnu.org>
4873
4874 * xdisp.c (string_buffer_position_lim): Limit starting position to
4875 BEGV.
4876 (set_cursor_from_row): If called for a mode-line or header-line
4877 row, return zero immediately.
4878 (try_cursor_movement): If inside continuation line, don't back up
4879 farther than the first row after the header line, if any.
4880 Don't consider the header-line row as "partially visible", even if
4881 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4882
48832012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4897 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
4898 -Wunused-result, -Wunused-variable. This should go away once
4899 the Emacs and Gnulib regex code is merged.
4900 (xmalloc, xrealloc): Now static.
4901
49022012-04-17 Paul Eggert <eggert@cs.ucla.edu>

4919 New extern decls, to avoid calling undeclared functions.
4920 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4921 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4922 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4923 (NEED_MEM_INSERT): New macro.
4924 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4925 Remove one incorrect comment and fix another.
4926

4935 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
4936 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
4937 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
4938 [REL_ALLOC]: ... to here, to check interface.
4939 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:

4953 (MARKER_BLOCK_SIZE, struct marker_block): Use union
4954 aligned_Lisp_Misc instead of union Lisp_Misc.
4955 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
4956
49572012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4958
4959 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4960 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4961 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4962 * s/netbsd.h, s/sol2-6.h:
4963 Remove definition of GC_MARK_STACK, since the default now works.
4964 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4965 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's

4968
49692012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4991
49922012-04-11 Daniel Colascione <dancol@dancol.org>
4993
4994 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4995 against is gone. It's better to use vfork now so that when Cygwin
4996 gains a new, working vfork, we use it automatically (bug#10398).
4997
49982012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4999
5000 * window.c (save_window_save): Obey window-point-insertion-type.

5022
5023 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5024 not just in the obarray, before snarfing them. (Bug#11036)
5025
5026 * Makefile.in ($(leimdir)/leim-list.el):
5027 Pass EMACS rather than BUILT_EMACS.
5028

5030
5031 * process.c (make_process):
5032 * process.h: Add integer `gnutls_handshakes_tried' member to
5033 process struct.
5034
5035 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5036 Add convenience `GNUTLS_LOG2i' macro.
5037
5038 * gnutls.c (gnutls_log_function2i): Convenience log function.
5039 (emacs_gnutls_read): Use new log functions,
5040 `gnutls_handshakes_tried' process member, and
5041 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5042 attempts per process (connection).
5043
50442012-04-09 Chong Yidong <cyd@gnu.org>
5045
5046 * eval.c (Fuser_variable_p, user_variable_p_eh)
5047 (lisp_indirect_variable): Functions deleted.
5048 (Fdefvar): Caller changed.

5052
50532012-04-09 Eli Zaretskii <eliz@gnu.org>
5054
5055 * xdisp.c (set_cursor_from_row): If the display string appears in
5056 the buffer at position that is closer to point than the position
5057 after the display string, display the cursor on the first glyph of
5058 the display string. Fixes cursor display when a 'display' text
5059 property immediately follows invisible text. (Bug#11094)
5060
50612012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5062
5063 composite.c: use 'double' consistently
5064 * composite.c (get_composition_id): Use 'double' consistently
5065 instead of converting 'float' to 'double' and vice versa; this is
5066 easier to understand and avoids a GCC warning.
5067
50682012-04-09 Glenn Morris <rgm@gnu.org>
5069
5070 * Makefile.in: Generate leim-list with bootstrap-emacs, in

5093 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5094 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5095 objects, as mark_maybe_pointer will catch them otherwise.
5096 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5097 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

5100
5101 Fix typo that broke non-Windows builds.
5102 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5105
5106 Support building on MS-Windows with libxml2.

5115 [!WINDOWSNT]: New macros.
5116 (init_libxml2_functions, libxml2_loaded_p): New functions.
5117 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5118 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5119 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5120 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5121 linked in).
5122 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5123 Call init_libxml2_functions before calling libxml2 functions.
5124 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5125
5126 * emacs.c: Don't include libxml/parser.h.

5129
5130 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5131
51322012-04-07 Eli Zaretskii <eliz@gnu.org>
5133
5134 * indent.c (Fvertical_motion): If there is a display string at
5135 point, use it.vpos to compute how many lines to backtrack after
5136 move_it_to point. (Bug#11133)
5137
51382012-04-06 Eli Zaretskii <eliz@gnu.org>
5139
5140 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5141 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5142 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5143 macros related to unification of CJK characters. For the details,
5144 see the discussion following the message here:
5145 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5146
51472012-04-04 Chong Yidong <cyd@gnu.org>
5148
5149 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5150
51512012-04-01 Eli Zaretskii <eliz@gnu.org>

5160
51612012-03-31 Eli Zaretskii <eliz@gnu.org>
5162
5163 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5164 position we get to after a call to move_it_to fails the
5165 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5166 only if we wind up in a string from display property. (Bug#11063)
5167
5168 * window.c (Fdelete_other_windows_internal): Invalidate the row
5169 and column information about mouse highlight, so that redisplay
5170 restores it after reallocating the glyph matrices. (Bug#7464)
5171
5172 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5173 string comes from a `display' text property, use the buffer
5174 position of that property as if we actually saw that position in
5175 the row's glyphs.
5176 (move_it_by_lines): Remove the assertion that
5177 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5178 violated when there's a before-string at the beginning of a line.
5179 (Bug#11063)
5180
51812012-03-30 Eli Zaretskii <eliz@gnu.org>
5182
5183 * xdisp.c (append_space_for_newline): If the default face was
5184 remapped, use the remapped face for the appended newline.
5185 (extend_face_to_end_of_line): Use the remapped default face for
5186 extending the face to the end of the line.
5187 (display_line): Call extend_face_to_end_of_line when the default
5188 face was remapped. (Bug#11068)
5189
51902012-03-29 Eli Zaretskii <eliz@gnu.org>
5191
5192 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5202
52032012-03-26 Kenichi Handa <handa@m17n.org>
5204
5205 * dispextern.h (struct glyph): Fix previous change. Change the
5206 bit length of glyphless.ch to 25 (Bug#11082).

5209
5210 * keyboard.c (Vselection_inhibit_update_commands): New variable.

5212 handle-select-window too (Bug#8996).
5213
52142012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5215
5216 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5217
52182012-03-25 Kenichi Handa <handa@m17n.org>
5219
5220 * dispextern.h (struct glyph): Change the bit length of
5221 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5222
52232012-03-24 Eli Zaretskii <eliz@gnu.org>
5224
5225 * s/ms-w32.h (tzname): Include time.h before redirecting to
5226 _tzname. Fixes the MSVC build. (Bug#9960)
5227
52282012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5229

5235
52362012-03-23 Eli Zaretskii <eliz@gnu.org>
5237
5238 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5239 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5240 when fetching a multibyte character consumes more bytes than
5241 CHAR_BYTES returns, due to unification of CJK characters in
5242 string_char. (Bug#11073)
5243
52442012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5245
5246 * process.c (wait_reading_process_output): Handle pty disconnect

5272
52732012-03-19 Kenichi Handa <handa@m17n.org>
5274
5275 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make

5279
5280 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5281 that is not from display property, accept the row as a "cursor
5282 row" if one of the string's character has a non-nil `cursor'
5283 property. Fixes cursor positioning when there are newlines in
5284 overlay strings, e.g. in icomplete.el. (Bug#11035)
5285
52862012-03-12 Paul Eggert <eggert@cs.ucla.edu>

5291
5292 * eval.c (inhibit_lisp_code): Rename from

5315
5316 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5317 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5318 zero (Bug#10954).
5319
53202012-03-03 Glenn Morris <rgm@gnu.org>
5321

5327 position past the first glyph_row that ends at ZV. (Bug#10902)
5328 (redisplay_window, next_element_from_string): Fix typos in
5329 comments.
5330 (redisplay_window): Pass to move_it_vertically the margin in
5331 pixels, not in screen lines.
5332
53332012-03-02 Glenn Morris <rgm@gnu.org>
5334

5346
5347 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5348 Suggested by Stefan Monnier in
5349 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5350 * alloc.c (widen_to_Lisp_Object): New static function.
5351 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5352 and widening them to Lisp_Objects. This would work even if
5353 USE_LSB_TAG is defined and wide integers are used, which might
5354 happen in a future version of Emacs.
5355
53562012-02-25 Chong Yidong <cyd@gnu.org>
5357
5358 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5359 Doc fix.
5360
5361 * xselect.c (Fx_selection_exists_p): Doc fix.

5363 before saving to clipboard manager.
5364
53652012-02-24 Chong Yidong <cyd@gnu.org>
5366
5367 * keyboard.c (process_special_events): Handle all X selection
5368 requests in kbd_buffer, not just the next one (Bug#8869).
5369
53702012-02-23 Chong Yidong <cyd@gnu.org>
5371
5372 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5373 call when setting menu-bar-lines and tool-bar-lines parameters.
5374 (unwind_create_frame_1): New helper function.
5375
5376 * window.c (inhibit_window_configuration_change_hook): New var.

5378 (syms_of_window): Initialize it.
5379
53802012-02-22 Chong Yidong <cyd@gnu.org>
5381

5395 when computing $valmask.
5396
5397 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5398 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5399 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5400 It's useless in that case, and it can cause problems on hosts
5401 that allocate halves of EMACS_INT values separately.
5402 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5403 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5404 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5405 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5406 it avoids undefined behavior on hosts where shifting right by more
5407 than the word width has undefined behavior.
5408
54092012-02-19 Chong Yidong <cyd@gnu.org>
5410
5411 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

5429 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5430
54312012-02-15 Chong Yidong <cyd@gnu.org>
5432
5433 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

5453
5454 * window.c (Fdelete_window_internal): Invalidate the mouse
5455 highlight (Bug#9904).
5456
54572012-02-12 Glenn Morris <rgm@gnu.org>

5531
5532 Handle overflow when computing char display width (Bug#9496).
5533 * character.c (char_width): Return EMACS_INT, not int.
5534 (char_width, c_string_width): Check for overflow when
5535 computing the width; this is possible now that individual
5536 characters can have unbounded width. Problem introduced
5537 by merge from Emacs 23 on 2012-01-19.
5538
55392012-02-02 Michael Albinus <michael.albinus@gmx.de>

5679 (Fmake_directory_internal): Use it.
5680 (do_auto_save_make_dir): Set it, instead of invoking chmod after
5681 creating the directory. The old code temporarily assigns

6186 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
6187 Otherwise, valgrind does not work on some platforms.
6188 Problem reported by Andreas Schwab in
6189 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6190 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6191 is set, removing the need for VIRT_ADDRESS_VARIES.
6192 (PURE_P): Use a more-efficient implementation that needs just one
6193 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6194 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6195 to 4 (xorl, subq, cmpq, setbe).
6196 * alloc.c (pure): Always extern now, since that's the
6197 VIRT_ADDR_VARIES behavior.
6198 (PURE_POINTER_P): Use a single comparison, not two, for
6199 consistency with the new puresize.h.
6200 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6201 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
6202 Remove VIRT_ADDR_VARIES no longer needed.

6207 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6208 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6209 behave as if the cursor position were at the window margin.
6210
6211 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6212 and the cursor position is out of bounds, behave as if the cursor
6213 position were at the window margin. (Bug#10075)
6214
62152011-11-18 Chong Yidong <cyd@gnu.org>
6216
6217 * window.c (Fwindow_combination_limit): Make first argument
6218 non-optional, since it is meaningless for live windows like the
6219 selected window.

62212011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
6222
6223 * keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

6234 (copy_row_except_pointers): Preserve the used[] arrays and the
6235 hash values of the two rows. (Bug#10035)
6236 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6237
6238 * xdisp.c (row_hash): New function, body extracted from
6239 compute_line_metrics.
6240 (compute_line_metrics): Call row_hash, instead of computing the
6241 hash code inline.
6242
6243 * dispnew.c (verify_row_hash): Call row_hash for computing the

6283
62842011-11-14 Eli Zaretskii <eliz@gnu.org>
6285
6286 * xdisp.c (display_line): Move the call to
6287 highlight_trailing_whitespace before the call to
6288 compute_line_metrics, since the latter needs to see the final
6289 faces of all the glyphs to compute ROW's hash value.
6290 Fixes assertion violations in row_equal_p. (Bug#10035)
6291
62922011-11-14 Juanma Barranquero <lekktu@gmail.com>
6293
6294 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
6295 just return (bug#10044).
6296
62972011-11-12 Eli Zaretskii <eliz@gnu.org>
6298
6299 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6300 with user-defined heap size. Bump the default size of the temacs
6301 heap to 27MB, to avoid memory warning when running temacs.
6302 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6303
6304 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
6305 current_matrix and desired_matrix. (Bug#9990)
6306 (verify_row_hash) [XASSERTS]: New function.

6353 Avoid some portability problems by eschewing 'extern inline' functions.
6354 The trivial performance wins aren't worth the portability hassles; see
6355 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6356 et seq.
6357 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6389
63902011-11-07 Martin Rudalics <rudalics@gmx.at>
6391

6404
6405 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6406 This is also needed for porting to any host where GC_MARK_STACK is
6407 not GC_MAKE_GCPROS_NOOPS.
6408 (which_symbols): Use it.
6409
64102011-11-07 Kenichi Handa <handa@m17n.org>
6411
6412 * coding.c (coding_set_destination): Check coding->src_pos only
6413 when coding->src_object is a buffer (bug#9910).

6422
6423 * xmenu.c (cleanup_widget_value_tree): New function.
6424 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
6425 calling free_menubar_widget_value_tree directly (Bug#9830).

6431 (window_box_width, window_box_left, window_box_left_offset)
6432 (window_box_right, window_box_right_offset): Declare extern.
6433 Otherwise, these inline functions do not conform to C99 and
6434 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6435 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6436 * intervals.c (adjust_intervals_for_insertion)
6437 (adjust_intervals_for_deletion): Now extern, because otherwise the
6438 extern inline functions 'offset_intervals' couldn't refer to it.
6439 (static_offset_intervals): Remove.
6440 (offset_intervals): Rewrite using the old contents of
6441 static_offset_intervals. The old version didn't conform to C99
6442 because an extern inline function contained a reference to an
6443 identifier with static linkage.
6444
64452011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6446

6464 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6465 (Fwindow_vscroll): Doc fix.
6466 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6467 argument, since it makes no sense to pass a live window and for
6468 consistency with window-child.

6500 Move terminal->reference_count++ just before making the frame official
6501 (Bug#9943).
6502

6508 Move terminal->reference_count++ just before making the frame
6509 official. Move initialization of image_cache_refcount and
6510 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

65122011-11-05 Eli Zaretskii <eliz@gnu.org>
6513
6514 Support MSVC build with newer versions of Visual Studio.
6515 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

6572
65732011-11-01 Eli Zaretskii <eliz@gnu.org>
6574
6575 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6576 Don't stop backward scan on the continuation glyph, even though
6577 its CHARPOS is positive.

6579 Rename cover_string to disp_string.
6580
65812011-11-01 Martin Rudalics <rudalics@gmx.at>
6582
6583 * window.c (temp_output_buffer_show): Don't use

6595 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6596 HAVE_GTK3 (Bug#9869).
6597
6598 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6599 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6600
6601 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6602
6603 * xterm.c: Declare x_handle_net_wm_state to return int.
6604 (handle_one_xevent): Check if we are iconified but don't have
6605 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6606 (get_current_wm_state): Return non-zero if not hidden,
6607 check for _NET_WM_STATE_HIDDEN (Bug#9893).

6613
6614 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6615 so that this new function doesn't get optimized away by a
6616 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6617
66182011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6619

6642
66432011-10-28 Eli Zaretskii <eliz@gnu.org>
6644
6645 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6646 possible random value that matches one of those tested as
6647 condition to clear the mouse face.
6648
66492011-10-28 Chong Yidong <cyd@gnu.org>
6650

6676 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6677 New functions.
6678 (w32font_open_internal, compute_metrics):
6679 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6680 instead of calling the "wide" APIs directly.
6681
6682 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6683

6694
6695 * process.c (make_process): Set gnutls_state to NULL.
6696
6697 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6698 non-NULL, regardless of GNUTLS_INITSTAGE.
6699 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6700 an error. Set process slots as soon as we allocate them.
6701
6702 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6703
67042011-10-27 Chong Yidong <cyd@gnu.org>

6725
67262011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6727

6742 * dispextern.h (struct bidi_it): New member next_en_type.
6743
6744 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6745 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6746 current character, check also for next_en_type being WEAK_EN.
6747 (bidi_resolve_weak): Don't enter the expensive loop if the current
6748 position is before next_en_pos. Record the bidi type of the first
6749 non-ET, non-BN character we find, in addition to its position.
6750 (bidi_level_of_next_char): Invalidate next_en_type when
6751 next_en_pos is over-stepped.
6752
67532011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6754
6755 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6756 * editfns.c: Rewrite current-time-zone so that it invokes
6757 the equivalent of (format-time-string "%Z") to get the time zone name.
6758 This fixes a bug when the time zone name contains characters that
6759 need converting from the system time locale to Emacs internal format.
6760 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6761 that patch fixed format-time-string to do the conversion, but
6762 I forgot to fix current-time-zone.
6763 (format_time_string): New function, containing most of
6764 what Fformat_time_string used to contain.
6765 (Fformat_time_string): Rewrite in terms of format_time_string.
6766 This doesn't change this function's behavior.
6767 (current-time-zone): Rewrite to use format_time_string.
6768 This fixes the bug reported by Michael Schierl in
6769 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6770 Jason Rumney's 2007-06-07 change worked around this bug, but
6771 didn't fix it.
6772 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6773
67742011-10-19 Eli Zaretskii <eliz@gnu.org>
6775
6776 * xdisp.c (start_display): If the character at POS is displayed
6777 via a display vector, reset IT->current.dpvec_index to zero.
6778 (try_window_reusing_current_matrix): If a line ends in a display
6779 vector or the next line starts in a display vector, continue
6780 redrawing the window even though the character position of
6781 start_row was reached.
6782 (Bug#9771, part 2)
6783
67842011-10-18 Chong Yidong <cyd@gnu.org>
6785
6786 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6787 with nobreak-char-display too.
6788
67892011-10-18 Eli Zaretskii <eliz@gnu.org>
6790
6791 Fix part 3 of bug#9771.
6792 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6793 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6794 non-neutral characters if the current character is a paragraph
6795 separator (a.k.a. Newline). This avoids running the same
6796 expensive loop twice, once when we consume the preceding newline
6797 and the other time when the line actually needs to be displayed.
6798 Avoid the loop when we see neutrals on the base embedding level
6799 following a character whose directionality is the same as the
6800 paragraph's. This avoids running the expensive loop when a line
6801 ends in a long sequence of neutrals, like control characters.
6802 Add assertion against STRONG_AL type. Slightly rearrange code
6803 that determines the type of a neutral given the first non-neutral
6804 that follows it.
6805 (bidi_level_of_next_char): Set next_en_pos to zero when
6806 invalidating its info.
6807
68082011-10-17 Eli Zaretskii <eliz@gnu.org>
6809
6810 * xdisp.c (push_display_prop): Determine whether to record string
6811 or buffer position by IT->string, not by IT->method. Allow
6812 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6813 (move_it_vertically_backward): Don't look for character position
6814 immediately after the newline when in a continuation line.
6815 (Bug#9771, part 1)
6816
68172011-10-15 Martin Rudalics <rudalics@gmx.at>
6818
6819 * window.c (coordinates_in_window): Rewrite and delabelize
6820 vertical border check. (Bug#5357) (Bug#9618)

6825 errors in XSetWindowBorder (bug#9310).
6826
68272011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6828
6829 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6830 avoid crash when xmalloc overrun checking is enabled.
6831
68322011-10-13 Eli Zaretskii <eliz@gnu.org>
6833
6834 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6835 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6836 cursor motion with <left> and <right> arrow keys.
6837
6838 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6839 some callers set that themselves.
6840
68412011-10-12 Eli Zaretskii <eliz@gnu.org>
6842
6843 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6844 display string and the previous row comes from the same string and
6845 is empty. (Bug#9739) (Bug#9738)
6846
68472011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6848

6855 comments regarding the Unicode Line Separator character.
6856
6857 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6858
68592011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6860
6861 * alloc.c (Fgc_status): Do not access beyond zombies array
6862 boundary if nzombies > MAX_ZOMBIES.
6863 * alloc.c (dump_zombies): Add missing format specifier.
6864
68652011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6866
6867 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6868 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6869
6870 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6871 Some packages use them to denote characters with modifiers.
6872
68732011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6874
6875 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6876 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6877 matching a pp-number. Rename parameter var to var1.
6878
68792011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6880
6881 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6882
68832011-10-08 Glenn Morris <rgm@gnu.org>
6884
6885 * callint.c (Fcall_interactively): Give a more explicit error for the
6886 'c' case with a non-character input. (Bug#8479)
6887
68882011-10-08 Eli Zaretskii <eliz@gnu.org>
6889
6890 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6891 lines.
6892 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6893 lines that are hscrolled on the left.
6894
6895 * dispnew.c (buffer_posn_from_coords): Account for a possible
6896 presence of header-line. (Bug#4426)
6897
68982011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6899
6900 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6901 Don't advertise functionality which we discourage or doesn't work.
6902
69032011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6904
6905 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6906 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6907 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6908 this makes Emacs dump core during garbage collection on rare
6909 occasions. sizeof is obviously inferior to offsetof here, so
6910 stick with offsetof.
6911 (GC_POINTER_ALIGNMENT): New macro.
6912 (mark_memory): Omit 3rd (offset) arg; caller changed.
6913 Don't assume EMACS_INT alignment is the same as pointer alignment.
6914
69152011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6916
6917 * keyboard.c (read_key_sequence_remapped): New var.

6919 (command_loop_1): Use read_key_sequence's remapping directly.
6920
69212011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6922
6923 * dired.c (file_name_completion): Don't expand file name.
6924 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6925 before checking file name handler.
6926
6927 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6928 they've been requested explicitly (bug#9591).
6929
69302011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6931
6932 * keymap.c (Fsingle_key_description): Use make_specified_string
6933 instead of build_string to build string from push_key_description.
6934 (Bug#5193)
6935
69362011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6937
6938 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6939 This fixes a Y2038 bug on 64-bit hosts.
6940 * buffer.c (reset_buffer):
6941 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6942 (Fclear_buffer_auto_save_failure):
6943 Use 0, not -1, to represent an unset failure time, since time_t
6944 might not be signed.
6945
6946 Remove dependency on glibc malloc internals.
6947 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6948 Move back here from lisp.h, but with their new implementations.
6949 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6950 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6951 * charset.c (charset_table_init): New static var.
6952 (syms_of_charset): Use it instead of xmalloc. This removes a
6953 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6954 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6955 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6956 Move back to alloc.c.
6957 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6958 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6959
69602011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6961
6962 * nsterm.m (windowDidResize): Call x_set_window_size only when
6963 ns_in_resize is true. Otherwise set pixelwidth/height and
6964 call change_frame_size (Bug#9628).

6968 Port --enable-checking=all to Fedora 14 x86-64.
6969 * charset.c (syms_of_charset): Also account for glibc malloc's
6970 internal overhead when calculating the initial malloc maximum.
6971
6972 Port --enable-checking=all to Fedora 14 x86.
6973 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6974 Move to lisp.h.
6975 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6976 (overrun_check_realloc, overrun_check_free):
6977 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6978 That way, xmalloc returns a properly-aligned pointer even if
6979 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6980 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6981 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6982 into account when calculating the initial malloc maximum.
6983 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6984 Move here from alloc.c, so that charset.c can use it too.
6985 Properly align; the old code wasn't right for common 32-bit hosts
6986 when configured with --enable-checking=all.
6987 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6988 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6989
69902011-09-29 Eli Zaretskii <eliz@gnu.org>
6991
6992 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6993 use EDOM.
6994
69952011-09-28 Eli Zaretskii <eliz@gnu.org>
6996
6997 * xdisp.c (compute_display_string_end): If there's no display
6998 string at CHARPOS, return -1.
6999
7000 * bidi.c (bidi_fetch_char): When compute_display_string_end
7001 returns a negative value, treat the character as a normal
7002 character not covered by a display string. (Bug#9624)
7003
70042011-09-28 Juanma Barranquero <lekktu@gmail.com>
7005
7006 * lread.c (Fread_from_string): Fix typo in docstring.
7007
70082011-09-27 Eli Zaretskii <eliz@gnu.org>
7009
7010 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7011 newline, reseat the iterator instead of bidi-iterating there one
7012 character at a time. (Bug#9610)
7013 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7014 TO_CHARPOS if the bidi iterator is at base embedding level.
7015
70162011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7017
7018 * lread.c (readevalloop): Use correct code for NBSP.
7019 (read1): Likewise. (Bug#9608)
7020
70212011-09-25 Michael Albinus <michael.albinus@gmx.de>
7022
7023 * dbusbind.c (Fdbus_register_signal): When service is not
7024 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7025
70262011-09-25 Glenn Morris <rgm@gnu.org>
7027
7028 * buffer.c (truncate-lines): Doc fix.
7029
70302011-09-24 Chong Yidong <cyd@stupidchicken.com>
7031
7032 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7033 (Fset_window_next_buffers): Doc fix.
7034
70352011-09-24 Glenn Morris <rgm@gnu.org>
7036
7037 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7038
70392011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7040
7041 Fix minor problems found by static checking.
7042 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7043 * indent.c (Fvertical_motion): Fix == vs = typo.
7044
70452011-09-24 Eli Zaretskii <eliz@gnu.org>
7046
7047 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7048 Default value is now t. Doc fix.
7049
7050 * indent.c (Fvertical_motion): Compute and apply the overshoot
7051 logic when moving up, not only when moving down. Fix the
7052 confusing name and values of the it_overshoot_expected variable;
7053 logic changes accordingly. (Bug#9254) (Bug#9549)
7054
7055 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7056 CHARPOS is covered by a display string which includes newlines.
7057 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7058 is covered by a display string with embedded newlines.
7059
70602011-09-24 Michael Albinus <michael.albinus@gmx.de>
7061
7062 * dbusbind.c (Fdbus_register_signal): Add match rule to
7063 Vdbus_registered_objects_table. (Bug#9581)
7064 (Fdbus_register_method, Vdbus_registered_objects_table):
7065 Fix docstring.
7066
70672011-09-24 Jim Meyering <meyering@redhat.com>
7068
7069 do not ignore write error for any output size
7070 The previous change was incomplete.
7071 While it makes emacs --batch detect the vast majority of stdout
7072 write failures, errors were still ignored whenever the output size is
7073 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7074 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7075 && echo FAIL: ignored write error
7076 FAIL: ignored write error
7077 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7078 && echo FAIL: ignored write error
7079 FAIL: ignored write error
7080 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7081
70822011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7083
7084 * emacs.c (Fkill_emacs): In noninteractive mode exit
7085 non-successfully if a write error occurred on stdout. (Bug#9574)
7086
70872011-09-21 Eli Zaretskii <eliz@gnu.org>
7088
7089 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7090 the xassert test.
7091
7092 * dispextern.h (struct it): Update the comment documenting what
7093 can it->OBJECT be.
7094
70952011-09-20 Eli Zaretskii <eliz@gnu.org>
7096
7097 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7098 a display string, extend search for cursor position to end of row.
7099 (find_row_edges): If the row ends in a newline from a display
7100 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7101 Handle the case of a display string with multiple newlines.
7102 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7103 non-empty line. Fixes confusing cursor motion with arrow keys at
7104 the beginning of a line that starts with whitespace.
7105
71062011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7107
7108 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7109 (bug#9493).
7110
71112011-09-18 Chong Yidong <cyd@stupidchicken.com>
7112
7113 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7114 boolean (Bug#9154).
7115
71162011-09-18 Eli Zaretskii <eliz@gnu.org>
7117
7118 * xdisp.c (display_line): Record maximum and minimum buffer
7119 positions even if no glyphs were produced (e.g., by a zero-width
7120 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7121 buffer positions that will be removed from the glyph row because
7122 they don't fit.
7123 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7124 column is beyond frame width: don't subtract 1 "pixel" when
7125 computing width of the stretch.
7126 (reseat_at_next_visible_line_start): Undo the change made on
7127 2011-09-17 that saved paragraph information and restored it after
7128 the call to `reseat'. (Bug#9545)
7129
71302011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7131
7132 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7133 and turn window cursor on if cleared (Bug#9415).
7134
71352011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7136
7137 * search.c (boyer_moore): Take unibyte characters from pattern
7138 literally. (Bug#9458)
7139
71402011-09-18 Eli Zaretskii <eliz@gnu.org>

71442011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7145
7146 Fix minor problem found by static checking.
7147 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7148 initialized, to pacify gcc -Wuninitialized.
7149
7150 * fileio.c: Report proper errno when syscall falls.
7151 (Finsert_file_contents): Save and restore errno,
7152 so that report_file_error outputs the correct diagnostic.
7153 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7154
71552011-09-18 Eli Zaretskii <eliz@gnu.org>
7156

7158
71592011-09-17 Eli Zaretskii <eliz@gnu.org>
7160
7161 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7162 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7163
71642011-09-17 Eli Zaretskii <eliz@gnu.org>
7165
7166 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7167 about the current paragraph and restore it after the call to reseat.
7168
7169 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7170 (bidi_find_paragraph_start): Search back for paragraph beginning
7171 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7172 (bidi_move_to_visually_next): Only trigger paragraph-related
7173 computations when the last character is a newline or at EOB, not
7174 just any NEUTRAL_B. (Bug#9470)
7175
7176 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7177 truncated lines if point is covered by a display string. (Bug#9524)
7178
71792011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7180
7181 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7182 (cons_to_x_long): New function.
7183 (lisp_data_to_selection_data): Use it. Correct the test for
7184 short-versus-long data; it was negated. Break out of vector
7185 loop, for efficiency, when a long datum is discovered.
7186
71872011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7188
7189 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7190
71912011-09-16 Eli Zaretskii <eliz@gnu.org>
7192
7193 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7194 GCC PR/17406) by declaring this function with external scope.
7195
71962011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7197
7198 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7199 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7200
72012011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7202

7213 of TAB characters in a composition.
7214
72152011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7216
7217 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7218 This occurs when processing a multibyte format.
7219 Problem reported by Wolfgang Jenker.
7220
72212011-09-15 Johan Bockgård <bojohan@gnu.org>
7222
7223 * xdisp.c (try_cursor_movement): Only check for exact match if
7224 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7225
72262011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7227
7228 Remove unused external symbols.

7234 * xterm.c, xterm.h (x_catching_errors): Remove.
7235
72362011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7237
7238 * xselect.c: Use signed conversions more consistently (Bug#9498).
7239 (selection_data_to_lisp_data): Assume incoming selection data are
7240 signed integers, not unsigned. This is to be consistent with
7241 outgoing selection data, which was modified to use signed integers
7242 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7243 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7244 expects long, not unsigned long.
7245
72462011-09-14 Eli Zaretskii <eliz@gnu.org>
7247
7248 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect

7251
72522011-09-13 Chong Yidong <cyd@stupidchicken.com>
7253
7254 * frame.c (Fother_visible_frames_p): Function deleted.
7255
72562011-09-12 Eli Zaretskii <eliz@gnu.org>
7257
7258 * indent.c (compute_motion): Process display vector front to back
7259 rather than the other way around. (Bug#2496)
7260
72612011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7262
7263 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7264
72652011-09-11 Chong Yidong <cyd@stupidchicken.com>
7266
7267 * minibuf.c (Fread_from_minibuffer): Doc fix.
7268
72692011-09-11 Eli Zaretskii <eliz@gnu.org>
7270
7271 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7272 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7273
72742011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7275
7276 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7277 value for non-existent files.
7278
72792011-09-11 Eli Zaretskii <eliz@gnu.org>
7280
7281 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7282 set its "size" to -1. This will set the modtime_size field of
7283 the corresponding buffer to -1, which is what
7284 verify-visited-file-modtime expects for files that do not exist.
7285 (Bug#9139)
7286
72872011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7288
7289 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7290 here ...
7291 * lisp.h: ... from here. push_key_description is no longer
7292 defined in keyboard.c, so its declaration should not be in
7293 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7294 logically belongs with push_key_description.
7295
72962011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7297
7298 * buffer.h: Include <sys/types.h> instead of <time.h>.
7299 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.

7301
73022011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>

7306
73072011-09-10 Andreas Schwab <schwab@linux-m68k.org>

7314 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7315 redisplay in small windows.
7316
73172011-09-09 Eli Zaretskii <eliz@gnu.org>
7318

7320
73212011-09-08 Martin Rudalics <rudalics@gmx.at>
7322
7323 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7324 Operate on live windows only.
7325
73262011-09-08 Juanma Barranquero <lekktu@gmail.com>
7327
7328 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.

73392011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7340
7341 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7342 Without this fix, the command to link temacs failed due to an
7343 undefined symbol __builtin_isnan. This is because
7344 /usr/include/iso/math_c99.h #defines isnan(x) to
7345 __builtin_isnan(x), but the bundled gcc, which identifies itself
7346 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7347 a __builtin_isnan.
7348 * floatfns.c (isnan): #undef, and then #define to a clone of
7349 what's in data.c.
7350 (Fisnan): Always define, since it's always available now.
7351 (syms_of_floatfns): Always define isnan at the Lisp level.
7352
73532011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7354
7355 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7356
73572011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7358
7359 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7360 The previous code assumed that file offsets (off_t values) fit in
7361 EMACS_INT variables, which is not true on typical 32-bit hosts.
7362 The code messed up by falsely reporting buffer overflow in cases
7363 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7364 when "big" contains more than 2**29 bytes, even though this
7365 inserts just one byte and does not overflow the buffer.
7366 (Finsert_file_contents): Store file offsets as off_t
7367 values, not as EMACS_INT values. Check for overflow when
7368 converting between EMACS_INT and off_t. When checking for
7369 buffer overflow or for overlap, take the offsets into account.
7370 Don't use EMACS_INT for small values where int suffices.
7371 When checking for overlap, fix a typo: ZV was used where
7372 ZV_BYTE was intended.
7373 (Fwrite_region): Don't assume off_t fits into 'long'.
7374 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7375
73762011-09-05 Michael Albinus <michael.albinus@gmx.de>
7377
7378 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7379
73802011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7381
7382 sprintf-related integer and memory overflow issues (Bug#9412).
7383
7384 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7385 (esprintf, exprintf, evxprintf): New functions.
7386 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7387 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7388 (modify_event_symbol): Do not assume that the length of
7389 name_alist_or_stem is safe to alloca and fits in int.
7390 (Fexecute_extended_command): Likewise for function name and binding.
7391 (Frecursion_depth): Wrap around reliably on integer overflow.
7392 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7393 since some callers pass EMACS_INT values.
7394 (Fsingle_key_description): Don't crash if symbol name contains more
7395 than MAX_ALLOCA bytes.
7396 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7397 (get_minibuffer): Arg is now EMACS_INT, not int.
7398 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7399 (esprintf, exprintf, evxprintf): New decls.
7400 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7401
7402 * dbusbind.c (signature_cat): New function.
7403 (xd_signature, Fdbus_register_signal):
7404 Do not overrun buffer; instead, report string overflow.
7405
7406 * dispnew.c (add_window_display_history): Don't overrun buffer.
7407 Truncate instead; this is OK since it's just a log.
7408
7409 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7410 even if the time zone offset is outlandishly large.
7411 Don't mishandle offset == INT_MIN.
7412
7413 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7414 when creating daemon; the previous buffer-overflow check was incorrect.
7415
7416 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7417 which has the guts of the old verror function.
7418
7419 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7420 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7421
7422 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7423 (font_unparse_xlfd): Don't blindly alloca long strings.
7424 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7425 fits in int, when using sprintf. Use single snprintf to count
7426 length of string rather than counting it via multiple sprintfs;
7427 that's simpler and more reliable.
7428 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7429 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7430 sprintf, in case result does not fit in int.
7431
7432 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7433 (fontset_from_font): Print it.
7434
7435 * frame.c (tty_frame_count): Now printmax_t, not int.
7436 (make_terminal_frame, set_term_frame_name): Print it.
7437 (x_report_frame_params): In X, window IDs are unsigned long,
7438 not signed long, so print them as unsigned.
7439 (validate_x_resource_name): Check for implausibly long names,
7440 and don't assume name length fits in 'int'.
7441 (x_get_resource_string): Don't blindly alloca invocation name;
7442 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7443 not fit in int.
7444
7445 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7446 (xg_check_special_colors, xg_set_geometry):
7447 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7448
7449 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7450 Use esprintf, not sprintf, in case result does not fit in int.
7451
7452 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7453 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7454 it as a large positive number.
7455 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7456 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7457
7458 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7459 in case result does not fit in int.
7460
7461 * print.c (float_to_string): Detect width overflow more reliably.
7462 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7463 buffer overrun. Don't assume list length fits in 'int'. Treat
7464 print length of 0 as 0, not as infinity; to be consistent with other
7465 uses of print length in this function. Don't overflow print length
7466 index. Don't assume hash table size fits in 'long', or that
7467 vectorlike size fits in 'unsigned long'.
7468
7469 * process.c (make_process): Use printmax_t, not int, to format
7470 process-name gensyms.
7471
7472 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7473
7474 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7475 to avoid potential buffer overrun.
7476
7477 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7478 if X resource line is longer than 512 bytes.
7479
7480 * xfns.c (x_window): Make sprintf buffer a bit bigger
7481 to avoid potential buffer overrun.
7482
7483 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7488
7489 Integer overflow fixes for scrolling, etc.
7490 Without these, Emacs silently mishandles large integers sometimes.
7491 For example, "C-u 4294967297 M-x recenter" was treated as if
7492 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7493
7494 * xdisp.c (try_window_id): Check Emacs fixnum range before
7495 converting to 'int'.
7496
7497 * window.c (window_scroll_line_based, Frecenter):
7498 Check that an Emacs fixnum is in range before assigning it to 'int'.
7499 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7500 values converted from Emacs fixnums.
7501 (Frecenter): Don't wrap around a line count if it is out of 'int'
7502 range; instead, treat it as an extreme value.
7503 (Fset_window_configuration, compare_window_configurations):
7504 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7505
7506 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7507 that can exceed INT_MAX. Check that EMACS_INT value is in range
7508 before assigning it to the (possibly-narrower) index.
7509 (match_limit): Don't assume that a fixnum can fit in 'int'.
7510
7511 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7512 exceed INT_MAX.
7513
7514 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7515 (Fvertical_motion): Don't wrap around LINES values that don't fit
7516 in 'int'. Instead, treat them as extreme values. This is good
7517 enough for windows, which can't have more than INT_MAX lines anyway.
7518
75192011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7520
7521 * Require libxml/parser.h to avoid compilation warning.
7522
7523 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7524
7525 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7526 since this reportedly can destroy thread storage.
7527
75282011-08-30 Chong Yidong <cyd@stupidchicken.com>
7529
7530 * syntax.c (find_defun_start): Update all cache variables if
7531 exiting early (Bug#9401).
7532
75332011-08-30 Eli Zaretskii <eliz@gnu.org>
7534
7535 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7536
7537 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7538 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7539 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7540
7541 * term.c (tty_append_glyph): New function.
7542 (produce_stretch_glyph): Static function and its prototype deleted.
7543
7544 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7545 Add prototypes.
7546
75472011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7548
7549 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7550 when checking :margin (Bug#9390).
7551 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7552 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7553 so that the name doesn't mislead. All uses changed.
7554
75552011-08-28 Johan Bockgård <bojohan@gnu.org>
7556
7557 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7558 set_tty_hooks.
7559
75602011-08-27 Eli Zaretskii <eliz@gnu.org>
7561
7562 * xdisp.c (move_it_to): Don't bail out early when reaching
7563 position beyond to_charpos, if we are scanning backwards.
7564 (move_it_vertically_backward): When DY == 0, make sure we get to
7565 the first character in the line after the newline.
7566
75672011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7568
7569 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7570 (ccl_driver): Do not generate an out-of-range pointer.
7571 (Fccl_execute_on_string): Remove unnecessary check for
7572 integer overflow, noted by Stefan Monnier in
7573 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7574 Remove a FIXME that didn't need fixing.
7575 Simplify the newly-introduced buffer reallocation code.
7576
75772011-08-27 Juanma Barranquero <lekktu@gmail.com>
7578
7579 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7580
75812011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7582
7583 Integer and memory overflow issues (Bug#9196).
7584
7585 * doc.c (get_doc_string): Rework so that
7586 get_doc_string_buffer_size is the actual buffer size, rather than
7587 being 1 less than the actual buffer size; this makes xpalloc more
7588 convenient.
7589
7590 * image.c (x_allocate_bitmap_record, cache_image):
7591 * xselect.c (Fx_register_dnd_atom):
7592 Simplify previous changes by using xpalloc.
7593
7594 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7595 since either will do and ptrdiff_t is convenient with xpalloc.
7596
7597 * charset.c (charset_table_size)
7598 (struct charset_sort_data.priority): Now ptrdiff_t.
7599 (charset_compare): Don't overflow if priorities differ greatly.
7600 (Fsort_charsets): Don't assume list length fits in int.
7601 Check for size-calculation overflow when allocating sort data.
7602 (syms_of_charset): Allocate an initial charset table that is
7603 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7604
7605 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7606
7607 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7608 The actual value is always <= INT_MAX, and leaving it unsigned made
7609 overflow checking harder.
7610
7611 * dispextern.h (struct glyph_matrix.rows_allocated)
7612 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7613 with xpalloc. The values are still always <= INT_MAX.
7614
7615 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7616
7617 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7618 (SAFE_NALLOCA): New macro.
7619
7620 * region-cache.c (struct boundary.pos, find_cache_boundary)
7621 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7622 (set_cache_region, invalidate_region_cache)
7623 (revalidate_region_cache, know_region_cache, region_cache_forward)
7624 (region_cache_backward, pp_cache):
7625 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7626 so that ptrdiff_t * can be passed to xpalloc.
7627 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7628 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7629 (pp_cache): Don't assume cache_len fits in int.
7630 * region-cache.h: Adjust extern decls to match.
7631
7632 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7633 EMACS_INT, since either will do, for xpalloc.
7634
7635 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7636 (xnmalloc, xnrealloc, xpalloc): New functions.
7637
7638 * bidi.c (bidi_shelve_header_size): New constant.
7639 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7640 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7641
7642 * bidi.c (bidi_cache_shrink):
7643 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7644 (overlay_strings):
7645 Don't update size of array until after memory allocation succeeds,
7646 because xmalloc/xrealloc may not return.
7647 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7648 now that we have proper integer overflow checking.
7649 (record_overlay_string, overlay_strings): Catch overflows when
7650 calculating size of overlay_str_buf.
7651
7652 * callproc.c (Fcall_process): Check for size overflow when
7653 calculating size of args2.
7654 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7655 Normally we prefer signed values, but sticking with ptrdiff_t would
7656 require adding more-complicated checks.
7657
7658 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7659 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7660 Redo buffer-overflow calculations to avoid integer overflow.
7661 Add a FIXME comment where memory seems to be over-allocated.
7662
7663 * character.c (Fstring): Check for size-calculation overflow.
7664
7665 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7666 unnecessary integer overflow. Check for size overflow.
7667 (encode_coding_object): Don't update size until xmalloc succeeds.
7668
7669 * composite.c (get_composition_id): Check for overflow in glyph
7670 length calculations.
7671
7672 Integer and memory overflow fixes for display code.
7673 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7674 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7675 (scrolling_window): Check for overflow in size calculations.
7676 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7687 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7688 (get_doc_string): Check for size calculation overflow.
7689 Don't update size until allocation succeeds.
7690 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7691 EMACS_INT, where ptrdiff_t will do.
7692 (Fsubstitute_command_keys): Check for string overflow.
7693
7694 * editfns.c (set_time_zone_rule): Don't assume environment length
7695 fits in int.
7696 (message_length): Now ptrdiff_t, not int.
7697 (Fmessage_box): Don't update size until allocation succeeds.
7698 Don't assume message length fits in int.
7699 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7700
7701 * emacs.c (main): Do not reallocate argv, since there is a null at
7702 the end that can be overwritten, and this way there's no need to
7703 worry about size-calculation overflow.
7704 (sort_args): Check for size-calculation overflow.
7705
7706 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7707 alloc succeeds.
7708 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7709
7710 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7711 (x_set_scroll_bar_width, x_figure_window_size):
7712 Check for integer overflow.
7713 (x_set_alpha): Do not assume XINT fits in int.
7714
7715 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7716 This is for the members text_lines, text_cols, total_lines, total_cols,
7717 where the system imposes an 'int' limit.
7718
7719 * fringe.c (Fdefine_fringe_bitmap):
7720 Don't update size until alloc works.
7721
7722 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7723 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7724
7725 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7726 Check for size-calculation overflow.
7727 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7728 do, as we prefer signed integers.
7729 (id_to_widget.max_size, id_to_widget.used)
7730 (xg_store_widget_in_map, xg_remove_widget_from_map)
7731 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7732 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7733 Use and return ptrdiff_t, not int.
7734 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7735 * gtkutil.h: Change prototypes to match the above.
7736
7737 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7738 are duplicate now that they've been promoted to lisp.h.
7739 (x_allocate_bitmap_record, x_alloc_image_color)
7740 (make_image_cache, cache_image, xpm_load):
7741 Don't update size until alloc is done.
7742 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7743 (x_detect_edges):
7744 Check for size calculation overflow.
7745 (ct_colors_allocated_max): New constant.
7746 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
7747 overflow.
7748
7749 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
7750 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
7751 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7752 Use ptrdiff_t, not int, to count maps.
7753 (read_char_minibuf_menu_prompt): Check for overflow in size
7754 calculations. Don't update size until allocation succeeds.
7755 Redo calculations to avoid overflow.
7756 * keyboard.h: Change prototypes to match the above.
7757
7758 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
7759 to count maps.
7760 (current_minor_maps): Check for size calculation overflow.

7782 (Fset_match_data): Don't assume list lengths fit in 'int'.
7783
7784 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7785 for command line length. Do not attempt to address one before the
7786 beginning of an array, as that's not portable.
7787
7788 * term.c (max_frame_lines): Remove; unused.
7789 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7790 not int.

7797
7798 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7801 until alloc done.
7802
7803 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
7804 Don't update size until alloc done.
7805 Redo size calculations to avoid overflow.
7806 Check for size calculation overflow.
7807 (main) [DEBUG]: Fix typo in invoking tparam1.
7808

7812
7813 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
7814 Use ptrdiff_t, not int, for sizes.
7815 (Finternal_make_lisp_face, cache_face):
7816 Check for size calculation overflow.
7817 (cache_face): Treat size calculation overflows as if they were
7818 memory exhaustion (the usual treatment), rather than aborting.
7819
7820 * xfns.c (x_encode_text, x_set_name_internal)
7821 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7822 sizes, since they can exceed INT_MAX in size. Check for size
7823 calculation overflow.
7824
7825 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
7826 (xg_select): Check for size calculation overflow.
7827 Don't update size until alloc done.
7828
7829 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7830 as sprintf is limited to int lengths.
7831
7832 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7833 (X_LONG_MIN): New macros.
7834 Use them to make the following changes clearer.
7835 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7836 This change doesn't affect the value now, but it may help remind
7837 future maintainers not to raise the value too much later.
7838 (SELECTION_QUANTUM): Remove, replacing with ...
7839 (selection_quantum): ... new function, which avoids overflow.
7840 All uses changed.
7841 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7842 assumption that selection length fits in 'int'.
7843 (x_reply_selection_request, x_handle_selection_request)
7844 (x_get_window_property, receive_incremental_selection)
7845 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7846 (lisp_data_to_selection_data, clean_local_selection_data):
7847 Use ptrdiff_t, not int, to record length of selection.
7848 (x_reply_selection_request, x_get_window_property)
7849 (receive_incremental_selection, x_property_data_to_lisp):
7850 Redo calculations to avoid overflow.
7851 (x_reply_selection_request): When sending hint, ceiling it at
7852 X_LONG_MAX rather than relying on wraparound overflow to send
7853 something.
7854 (x_get_window_property, receive_incremental_selection)
7855 (lisp_data_to_selection_data, x_property_data_to_lisp):
7856 Check for size-calculation overflow.
7857 (x_get_window_property, receive_incremental_selection)
7858 (lisp_data_to_selection_data, Fx_register_dnd_atom):
7859 Don't store size until memory allocation succeeds.
7860 (x_get_window_property): Plug memory leak on memory exhaustion.
7861 Don't double-block input; malloc is safe here. Don't assume 2**34
7862 - 4 fits in unsigned long. Add an xassert to check
7863 XGetWindowProperty overflow. Be more careful about overflow
7864 calculations, and distinguish size from memory overflow better.
7865 (receive_incremental_selection): When tracing, don't assume
7866 unsigned int is less than INT_MAX.
7867 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7868 harmful) conversions of unsigned short to int.
7869 (lisp_data_to_selection_data): Don't assume that integers
7870 in the range -65535 through -1 fit in an X unsigned short.
7871 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7872 result parameters unless successful. Rely on cons_to_unsigned
7873 to report problems with elements; the old code wasn't right anyway.
7874 (x_check_property_data): Check for int overflow; we cannot use
7875 a wider type due to X limits.
7876 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7877
7878 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7879
7880 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7881 (x_term_init): Check for size calculation overflow.
7882 (x_color_cells): Don't store size until memory allocation succeeds.
7883 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
7884 Don't assume alloca size is less than MAX_ALLOCA.
7885 (x_term_init): Don't assume length fits in int (sprintf is limited
7886 to int size).
7887
7888 Use ptrdiff_t for composition IDs.
7889 * character.c (lisp_string_width):
7890 * composite.c (composition_table_size, n_compositions)

7907 * image.c (xpm_get_color_table_h):
7908 * lisp.h (hash_lookup, hash_put):
7909 * minibuf.c (Ftest_completion):
7910 Use ptrdiff_t for hash table indexes, not int (which is too
7911 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7912 32-bit --with-wide-int hosts).
7913
7914 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7915 Add a FIXME comment about memory leaks.
7916 (syms_of_charset): Don't assume xmalloc returns.
7917
7918 Don't assume that stated character widths fit in int.
7919 * character.c (Fchar_width, c_string_width, lisp_string_width):
7920 * character.h (CHAR_WIDTH):
7921 * indent.c (MULTIBYTE_BYTES_WIDTH):
7922 Use sanitize_char_width to avoid undefined and/or bad behavior
7923 with outlandish widths.
7924 * character.h (sanitize_tab_width): Rename from sanitize_width,
7925 now that we have two such functions. All uses changed.
7926 (sanitize_char_width): New inline function.
7927
7928 Don't assume that tab-width fits in int.
7929 * character.h (sanitize_width): New inline function.

7936 * fileio.c: Integer overflow issues with file modes.
7937 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7938
7939 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
7940 Remove unreachable code.
7941 (read_hex, load_charset_map_from_file): Check for integer overflow.
7942
7943 * xterm.c: Don't go over XClientMessageEvent limit.
7944 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7945 (x_send_scroll_bar_event): Likewise. Check that the size does not
7946 exceed limits imposed by XClientMessageEvent, as well as the usual
7947 ptrdiff_t and size_t limits.
7948
7949 * keyboard.c: Overflow, signedness and related fixes.
7950 (make_lispy_movement): Use same integer type in forward decl
7951 that is used in the definition.
7952 (read_key_sequence, keyremap_step):
7953 Change bufsize argument back to int, undoing my 2011-03-30 change.
7954 We prefer signed types, and int is wide enough here.
7955 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7956 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7957 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7958 length, not size_t. Use ptrdiff_t for index, not int.
7959 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7960 possibility of integer overflow.
7961
7962 Overflow, signedness and related fixes for images.

7971 * nsmenu.m (update_frame_tool_bar):
7972 * xdisp.c (calc_pixel_width_or_height):
7973 * xfns.c (image_cache_refcount):
7974 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7975 on typical 64-bit hosts.
7976
7977 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7978 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7979 Omit unnecessary casts to int.

7981 when the callers expect that.
7982 (image_ascent): Redo ascent calculation to avoid int overflow.
7983 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7984 (lookup_image): Remove unnecessary tests.
7985 (xbm_image_p): Locals are now of int, not EMACS_INT,
7986 since parse_image_check makes sure they fit into int.
7987 (png_load, gif_load, svg_load_image):
7988 Prefer int to unsigned where either will do.
7989 (tiff_handler): New function, combining the cores of the
7990 old tiff_error_handler and tiff_warning_handler.
7991 This function is rewritten to use vsnprintf and thereby avoid
7992 stack buffer overflows. It uses only the features of vsnprintf
7993 that are common to both POSIX and native Microsoft.
7994 (tiff_error_handler, tiff_warning_handler): Use it.
7995 (tiff_load, gif_load, imagemagick_load_image):
7996 Don't assume :index value fits in 'int'.
7997 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7998 (imagemagick_load_image): Check that crop parameters fit into
7999 the integer types that MagickCropImage accepts. Don't assume
8000 Vimagemagick_render_type has a nonnegative value. Don't assume
8001 size_t fits in 'long'.
8002 (gs_load): Use printmax_t to print the widest integers possible.
8003 Check for integer overflow when computing image height and width.

8006
8007 * xdisp.c (redisplay_window): Don't force window start if point
8008 will be invisible in the resulting window. (Bug#9324)
8009
80102011-08-25 Eli Zaretskii <eliz@gnu.org>
8011
8012 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8013 the display spec is of the form `(space ...)'.
8014 (handle_display_spec): Return the value returned by
8015 handle_single_display_spec, not just 1 or zero.
8016 (handle_single_display_spec): If the display spec is of the form
8017 `(space ...)', and specifies display in the text area, return 2
8018 rather than 1.
8019 (try_cursor_movement): Check for the need to scroll more
8020 accurately, and prefer exact match for point under bidi.
8021 Don't advance `row' beyond the last row of the window.
8022
8023 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8024 into disp_prop; all users changed.
8025
8026 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8027 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character

8039 buffers, return left-to-right.
8040 (set_cursor_from_row): Consider candidate row a win if its glyph
8041 represents a newline and point is on that newline. Fixes cursor
8042 positioning on the newline at EOL of R2L text within L2R
8043 paragraph, and vice versa.
8044 (try_cursor_movement): Check continued rows, in addition to
8045 continuation rows. Fixes unwarranted scroll when point enters a
8046 continued line of R2L text within an L2R paragraph, or vice versa.
8047 (cursor_row_p): Consider the case of point being equal to
8048 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8049 from the end of a short line to the beginning of a continued line
8050 of R2L text within L2R paragraph.
8051 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8052 composed characters.

8073
8074 * xdisp.c (redisplay_window): When computing centering_position,
8075 account for the height of the header line. (Bug#8874)
8076
8077 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8078 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8079 candidate is selected by the mouse, and that candidate has a
8080 composed character under the mouse.
8081
8082 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8083 coordinates reported by pos-visible-in-window-p for a composed
8084 character in column zero.

8091
8092 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8093 consider it a hit if to_charpos is anywhere in the range of the
8094 composed buffer positions.
8095
80962011-08-22 Chong Yidong <cyd@stupidchicken.com>
8097
8098 * image.c (gif_load): Don't assume that each subimage has the same
8099 dimensions as the base image. Handle disposal method that is
8100 "undefined" by the gif spec (Bug#9335).
8101
81022011-08-20 Chong Yidong <cyd@stupidchicken.com>

8116 with a composed character.
8117
81182011-08-18 Eli Zaretskii <eliz@gnu.org>
8119
8120 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8121 character bidirectional type, use STRONG_L instead. Fixes crashes
8122 in a buffer produced by `describe-categories'.
8123
8124 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8125 members before the level stack, so they would be saved and
8126 restored when copying iterator state. Fixes incorrect reordering
8127 around TABs covered by display properties.
8128

8229 (QCgnutls_bootprop_callbacks_verify): Rename from
8230 Qgnutls_bootprop_..., all uses changed.
8231
8232 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8233 uses changed.
8234
82352011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8236
8237 * xfaces.c (Qframe_set_background_mode): Now static.
8238 * dispextern.h (Qframe_set_background_mode): Remove decl.
8239
8240 * process.c (Fnetwork_interface_info): Declare local only if needed.
8241
82422011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8243
8244 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8245 (Fnetwork_interface_list): Allocate in increments of bytes instead
8246 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8247 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8248 sockaddr.
8249 (struct ifflag_def): notrailers is smart on OSX.
8250 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8251 Get hardware address with getifaddrs if available.
8252
82532011-08-12 Eli Zaretskii <eliz@gnu.org>
8254
8255 * xdisp.c (iterate_out_of_display_property): xassert that
8256 IT->position is set to within IT->object's boundaries. Break from
8257 the loop as soon as EOB is reached; avoids infloops in redisplay
8258 when IT->position is set up wrongly due to some bug.
8259 Set IT->current to match the bidi iterator unconditionally.
8260 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8261 entry. Force push_it to save on the stack the current
8262 buffer/string position, to be restored by pop_it. Fix flags in
8263 the iterator structure wrt the object coming from a display
8264 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8265 properties. (Bug#9284)
8266
82672011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8268
8269 * fontset.c (fontset_get_font_group): Add proper type checks.
8270 (Bug#9172)
8271
82722011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8273
8274 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8275 and LC_VERSION_MIN_MACOSX.
8276 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8277 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8278
82792011-08-08 Eli Zaretskii <eliz@gnu.org>
8280
8281 * xdisp.c (forward_to_next_line_start): Allow to use the
8282 no-display-properties-and-no-overlays under bidi display.
8283 Set disp_pos in the bidi iterator to avoid searches for display
8284 properties and overlays.
8285
82862011-08-08 Chong Yidong <cyd@stupidchicken.com>
8287
8288 * editfns.c (Fset_time_zone_rule): Document relationship with the
8289 setenv function.
8290
8291 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8292 the font entity extracted from the cache (Bug#8109).
8293
82942011-08-07 Chong Yidong <cyd@stupidchicken.com>
8295
8296 * composite.c (autocmp_chars): Don't reset point. That is done by
8297 restore_point_unwind (Bug#5984).
8298
82992011-08-07 Juri Linkov <juri@jurta.org>
8300
8301 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8302 to show the arg `TIME' instead of `TIMEVAL'.
8303
83042011-08-06 Eli Zaretskii <eliz@gnu.org>
8305
8306 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8307 display property strides EOL and includes a newline, as in
8308 longlines-mode. (Bug#9254)
8309 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8310 word-wrap under bidirectional display. (Bug#9224)
8311
8312 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8313 is non-zero, even if the data buffer is NULL. Fixes a crash in
8314 vertical-motion with longlines-mode. (Bug#9254)
8315
83162011-08-05 Eli Zaretskii <eliz@gnu.org>
8317
8318 * bidi.c <bidi_cache_total_alloc>: Now static.
8319 (bidi_initialize): Initialize bidi_cache_total_alloc.
8320
8321 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8322 cache. (Bug#9221)
8323
8324 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8325 amount allocated this far in `bidi_cache_total_alloc'.
8326 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8327 non-zero, only free the data buffer without restoring the cache
8328 contents. All callers changed.
8329
8330 * dispextern.h (bidi_unshelve_cache): Update prototype.
8331
8332 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8333 (move_it_in_display_line, move_it_to)
8334 (move_it_vertically_backward, move_it_by_lines): Replace the call
8335 to xfree to an equivalent call to bidi_unshelve_cache.
8336 (move_it_in_display_line_to): Fix logic of returning
8337 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8338
83392011-08-05 Eli Zaretskii <eliz@gnu.org>
8340
8341 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8342 came from a string character with a `cursor' property. (Bug#9229)
8343
83442011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8345
8346 * Makefile.in (LIB_PTHREAD): New variable.
8347 (LIBES): Add LIB_PTHREAD (Bug#9216).
8348
8349 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8350 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8351
83522011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8353
8354 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8355
83562011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8357
8358 * xterm.c (x_find_topmost_parent): New function.
8359 (x_set_frame_alpha): Find topmost parent window with
8360 x_find_topmost_parent and set the property there also (bug#9181).
8361 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8362
83632011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8364
8365 * callproc.c (Fcall_process): Avoid vfork clobbering
8366 the local vars buffer, coding_systems, current_dir.
8367
83682011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8369
8370 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8371
83722011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8373
8374 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8375 so that it is not optimized away.
8376
8377 * xdisp.c (compute_display_string_pos): Remove unused local.
8378
83792011-08-02 Eli Zaretskii <eliz@gnu.org>
8380
8381 Fix slow cursor motion and scrolling in large buffers with
8382 selective display, like Org Mode buffers. (Bug#9218)
8383
8384 * dispextern.h (struct bidi_it): New member disp_prop_p.
8385
8386 * xdisp.c: Remove one-slot cache of display string positions.
8387 (compute_display_string_pos): Accept an additional argument
8388 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8389 for a display string or property. If found, set DISP_PROP_P
8390 non-zero.
8391
8392 * bidi.c (bidi_fetch_char): Accept an additional argument
8393 DISP_PROP_P, and pass it to compute_display_string_pos.
8394 Only handle text covered by a display string if DISP_PROP_P is returned
8395 non-zero. All callers of bidi_fetch_char changed.
8396
83972011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8398
8399 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8400
84012010-12-03 Don March <don@ohspite.net>
8402
8403 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8404 last character M-[char] is translated to ESC [char] (bug#7541).
8405
84062011-08-02 Kenichi Handa <handa@m17n.org>
8407
8408 * lisp.h (uniprop_table): Extern it.
8409
8410 * chartab.c (uniprop_table): Make it non-static.
8411
84122011-08-01 Eli Zaretskii <eliz@gnu.org>
8413
8414 * xdisp.c (forward_to_next_line_start): Accept additional argument
8415 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8416 on the newline.
8417 (reseat_at_next_visible_line_start): Use the bidi iterator state
8418 returned by forward_to_next_line_start to restore the state of
8419 it->bidi_it after backing up to previous newline. (Bug#9212)
8420
84212011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8422
8423 * regex.c (re_comp): Protoize.
8424 (re_exec): Fix return type.
8425 (regexec): Fix type of `ret'. (Bug#9203)
8426
84272011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8428
8429 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8430 This is needed if max-image-size is a floating-point number.
8431
84322011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8433
8434 * print.c (print_object): Print empty symbol as ##.
8435
8436 * lread.c (read1): Read ## as empty symbol.
8437
84382011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8439
8440 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8441 setting frame foreground color (Bug#9175).
8442 (x_set_background_color): Likewise.
8443
8444 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8445 contents (Bug#9176).
8446 (EmacsTooltip -init): Remove bezels and add shadows to
8447 tooltip windows.
8448
8449 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8450 or scroll bar (Bug#8470).
8451
8452 * nsfont.m (nsfont_open): Remove assignment to voffset and
8453 unnecessary vars hshink, expand, hd, full_height, min_height.
8454 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8455
8456 * nsterm.h (nsfont_info): Remove voffset field.
8457
84582011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8459
8460 Implement strike-through and overline on NextStep (Bug#8863).
8461
8462 * nsfont.m (nsfont_open): Use underline position provided by font,
8463 instead of hard-coded value of 2.
8464 (nsfont_draw): Call ns_draw_text_decoration instead.
8465
8466 * nsterm.h: Add declaration for ns_draw_text_decoration.
8467
8468 * nsterm.m (ns_draw_text_decoration): New function for drawing
8469 underline, overline, and strike-through.
8470 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8471 ns_draw_text_decoration. Change treatment of cursor drawing to
8472 accommodate underlining, etc.
8473
84742011-07-28 Eli Zaretskii <eliz@gnu.org>
8475
8476 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8477 default.
8478
84792011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8480
8481 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8482 Without this fix, if a signal arrives just after memory fills up,
8483 'malloc' might be invoked reentrantly.
8484
8485 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8486 In other words, assume that every image size is allowed, on non-X
8487 hosts. This assumption is probably wrong, but it lets Emacs compile.
8488
84892011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8490
8491 * regex.c (re_iswctype): Convert return values to boolean.
8492
84932011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8494
8495 * xdisp.c (compute_display_string_pos): Don't use cached display
8496 string position if the buffer had its restriction changed.
8497 (Bug#9184)
8498
84992011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8500
8501 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8502
85032011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8504
8505 Integer signedness and overflow and related fixes. (Bug#9079)
8506
8507 * bidi.c: Integer size and overflow fixes.
8508 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8509 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8510 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8511 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8512 (bidi_find_other_level_edge):
8513 Use ptrdiff_t instead of EMACS_INT where either will do.
8514 This works better on 32-bit hosts configured --with-wide-int.
8515 (bidi_cache_ensure_space): Check for size-calculation overflow.
8516 Use % rather than repeated addition, for better worst-case speed.
8517 Don't set bidi_cache_size until after xrealloc returns, because it
8518 might not return.
8519 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8520 (bidi_cache_ensure_space): Also check that the bidi cache size
8521 does not exceed that of the largest Lisp string or buffer. See Eli
8522 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8523
8524 * alloc.c (__malloc_size_t): Remove.
8525 All uses replaced by size_t. See Andreas Schwab's note
8526 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8527
8528 * image.c: Improve checking for integer overflow.
8529 (check_image_size): Assume that f is nonnull, since
8530 it is always nonnull in practice. This is one less thing to
8531 worry about when checking for integer overflow later.
8532 (x_check_image_size): New function, which checks for integer
8533 overflow issues inside X.
8534 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8535 This removes the need for a memory_full check.
8536 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8537 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8538 (xbm_read_bitmap_data): Change locals back to 'int', since
8539 their values must fit in 'int'.
8540 (xpm_load_image, png_load, tiff_load):
8541 Invoke x_create_x_image_and_pixmap earlier,
8542 to avoid much needless work if the image is too large.
8543 (tiff_load): Treat overly large images as if
8544 x_create_x_image_and_pixmap failed, not as malloc failures.
8545 (gs_load): Use x_check_image_size.
8546
8547 * gtkutil.c: Omit integer casts.
8548 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8549 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8550
8551 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8552
8553 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8554 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8555 would wrongly return t on a 64-bit host.
8556
8557 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8558 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8559 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8560 and therefore cause GCC to emit a bogus diagnostic in some cases.
8561
8562 * image.c: Integer signedness and overflow and related fixes.
8563 This is not an exhaustive set of fixes, but it's time to
8564 record what I've got.
8565 (lookup_pixel_color, check_image_size): Remove redundant decls.
8566 (check_image_size): Don't assume that arbitrary EMACS_INT values
8567 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8568 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8569 (tiff_load, imagemagick_load_image):
8570 Check for overflow in size calculations.
8571 (x_create_x_image_and_pixmap): Remove unnecessary test for
8572 xmalloc returning NULL; that can't happen.
8573 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8574 (xpm_color_bucket): Use better integer hashing function.
8575 (xpm_cache_color): Don't possibly over-allocate memory.
8576 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8577 (gif_memory_source):
8578 Use ptrdiff_t, not int or size_t, to record sizes.
8579 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8580 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8581 either works, as we prefer signed integers.
8582 (tiff_read_from_memory, tiff_write_from_memory):
8583 Return tsize_t, not size_t, since that's what the TIFF API wants.
8584 (tiff_read_from_memory): Don't fail simply because the read would
8585 go past EOF; instead, return a short read.
8586 (tiff_load): Omit no-longer-needed casts.
8587 (Fimagemagick_types): Don't assume size fits into 'int'.
8588
8589 Improve hashing quality when configured --with-wide-int.
8590 * fns.c (hash_string): New function, taken from sxhash_string.
8591 Do not discard information about ASCII character case; this
8592 discarding is no longer needed.
8593 (sxhash-string): Use it. Change sig to match it. Caller changed.
8594 * lisp.h: Declare it.
8595 * lread.c (hash_string): Remove, since we now use fns.c's version.
8596 The fns.c version returns a wider integer if --with-wide-int is
8597 specified, so this should help the quality of the hashing a bit.
8598
8599 * emacs.c: Integer overflow minor fix.
8600 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8601 Define only if GNU_LINUX.
8602 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8603
8604 * dispnew.c: Integer signedness and overflow fixes.
8605 Remove unnecessary forward decls, that were a maintenance hassle.
8606 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8607 All uses changed.
8608 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8609 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8610 (prepare_desired_row, line_draw_cost):
8611 Use int, not unsigned, where either works.
8612 (save_current_matrix, restore_current_matrix):
8613 Use ptrdiff_t, not size_t, where either works.
8614 (init_display): Check for overflow more accurately, and without
8615 relying on undefined behavior.
8616
8617 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8618 Remove, replacing with the new symbols in lisp.h. All uses changed.
8619 * fileio.c (make_temp_name):
8620 * filelock.c (lock_file_1, lock_file):
8621 * xdisp.c (message_dolog):
8622 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8623 Use pMd etc. instead.
8624 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8625 replacing the pWIDE etc. symbols removed from editfns.c.
8626
8627 * keyboard.h (num_input_events): Now uintmax_t.
8628 This is (very slightly) less likely to mess up due to wraparound.
8629 All uses changed.
8630
8631 * buffer.c: Integer signedness fixes.
8632 (alloc_buffer_text, enlarge_buffer_text):
8633 Use ptrdiff_t rather than size_t when either will do, as we prefer
8634 signed integers.
8635
8636 * alloc.c: Integer signedness and overflow fixes.
8637 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8638 (__malloc_size_t): Default to size_t, not to int.
8639 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8640 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8641 Prefer ptrdiff_t to size_t when either would do, as we prefer
8642 signed integers.
8643 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8644 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8645 Now const. Initialize with values that are in range even if char
8646 is signed.
8647 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8648 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8649 These functions do the right thing with sizes > 2**32.
8650 (check_depth): Now ptrdiff_t, not int.
8651 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8652 Adjust to new way of storing sizes. Check for size overflow bugs
8653 in rest of code.
8654 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8655 slightly wrong anyway, as it missed one instance of
8656 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8657 (refill_memory_reserve): Omit needless cast to size_t.
8658 (mark_object_loop_halt): Mark as externally visible.
8659
8660 * xselect.c: Integer signedness and overflow fixes.
8661 (Fx_register_dnd_atom, x_handle_dnd_message):
8662 Use ptrdiff_t, not size_t, since we prefer signed.
8663 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8664 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8665 x_dnd_atoms_size and x_dnd_atoms_length.
8666
8667 * doprnt.c: Prefer signed to unsigned when either works.
8668 * eval.c (verror):
8669 * doprnt.c (doprnt):
8670 * lisp.h (doprnt):
8671 * xdisp.c (vmessage):
8672 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8673 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8674 prefer signed arithmetic to avoid comparison confusion.
8675 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8676 but is a bit tricky.
8677
8678 Assume freestanding C89 headers, string.h, stdlib.h.
8679 * data.c, doprnt.c, floatfns.c, print.c:
8680 Include float.h unconditionally.
8681 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8682 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8683 * regex.c: Likewise for stddef.h, string.h.
8684 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8685 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8686 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8687 (STDC_HEADERS): Remove obsolete defines.
8688 * sysdep.c: Include limits.h unconditionally.
8689
8690 Assume support for memcmp, memcpy, memmove, memset.
8691 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8692 * regex.c (memcmp, memcpy):
8693 Remove; we assume C89 now.
8694
8695 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8696 (__malloc_safe_bcopy): Remove; no longer needed.
8697
8698 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8699 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8700 well either way, and we prefer signed to unsigned.
8701
87022011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8703
8704 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8705 closes the connection while we're reading (bug#9182).
8706
87072011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8708
8709 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8710 are specified (Bug#9168).
8711
87122011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8713
8714 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8715 Found by GCC static checking and --with-wide-int on a 32-bit host.
8716
87172011-07-25 Eli Zaretskii <eliz@gnu.org>
8718
8719 * xdisp.c (compute_display_string_pos): Fix logic of caching
8720 previous display string position. Initialize cached_prev_pos to
8721 -1. Fixes slow-down at the beginning of a buffer.
8722
87232011-07-24 Eli Zaretskii <eliz@gnu.org>
8724
8725 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8726 for attrs[LFACE_FONTSET_INDEX].
8727
87282011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8729
8730 * xml.c (parse_region): Remove unused local
8731 that was recently introduced.
8732
87332011-07-23 Eli Zaretskii <eliz@gnu.org>
8734
8735 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8736 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8737
8738 * xdisp.c (move_it_in_display_line_to): Record the best matching
8739 position for TO_CHARPOS while scanning the line, and restore it on
8740 exit if none of the characters scanned was an exact match.
8741 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8742 when exact match is impossible due to invisible text, and the
8743 lines are truncated.
8744
87452011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8746
8747 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8748 for OSX >= 10.7.
8749
87502011-07-22 Eli Zaretskii <eliz@gnu.org>
8751
8752 Fix a significant slow-down of cursor motion with C-n, C-p,
8753 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8754 auto-repeat under bidi redisplay in fontified buffers.
8755 * xdisp.c (compute_stop_pos_backwards): New function.
8756 (next_element_from_buffer): Call compute_stop_pos_backwards to
8757 find a suitable prev_stop when we find ourselves before
8758 base_level_stop.
8759 (reseat): Don't look for prev_stop, as that could mean a very long
8760 run.
8761 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8762 <cached_disp_overlay_modiff>: Cache for last found display string
8763 position.
8764 (compute_display_string_pos): Return the cached position if asked
8765 about the same buffer in the same area of character positions, and
8766 the buffer wasn't changed since the time the display string
8767 position was cached.
8768
87692011-07-22 Eli Zaretskii <eliz@gnu.org>
8770
8771 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8772 is an integer, which is important for empty lines. (Bug#9149)
8773
87742011-07-22 Chong Yidong <cyd@stupidchicken.com>
8775
8776 * frame.c (Fmodify_frame_parameters): In tty case, update the
8777 default face if necessary (Bug#4238).
8778
87792011-07-21 Chong Yidong <cyd@stupidchicken.com>
8780
8781 * editfns.c (Fstring_to_char): No need to explain what a character
8782 is in the docstring (Bug#6576).
8783
87842011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8785
8786 * xml.c (parse_region): Make sure we always return a tree.
8787
87882011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8789
8790 * xml.c (parse_region): If a document contains only comments,
8791 return that, too.
8792
87932011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8794
8795 * xml.c (make_dom): Return comments, too.
8796
87972011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8798
8799 Port to OpenBSD.
8800 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8801 and the surrounding thread.
8802 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8803 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8804 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8805 timer goes off.
8806 * s/openbsd.h (BROKEN_SIGIO): Define.
8807 * unexelf.c (unexec) [__OpenBSD__]:
8808 Don't update the .mdebug section of the Alpha COFF symbol table.
8809
88102011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8811
8812 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8813 (bug#8460).
8814
88152011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8816
8817 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8818 This fixes some race conditions on the permissions of any newly
8819 created file.
8820
8821 * alloc.c (valid_pointer_p): Use pipe, not open.
8822 This fixes some permissions issues when debugging.
8823
8824 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8825 If fchown fails to set both uid and gid, try to set just gid,
8826 as that is sometimes allowed. Adjust the file's mode to eliminate
8827 setuid or setgid bits that are inappropriate if fchown fails.
8828
88292011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8830
8831 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8832 to compare Lisp_Objects.
8833 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8834 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8835 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8836
88372011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8838
8839 * lread.c (read_integer): Unread even EOF character.
8840 (read1): Likewise. Properly record start position of symbol.
8841
8842 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8843 symbol character follows.
8844
88452011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8846
8847 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8848 This works around a problem with the previous change to Fcopy_file.
8849 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8850 and without this change, GCC might complain about discarding
8851 fchown's return value.
8852
88532011-07-16 Juanma Barranquero <lekktu@gmail.com>
8854
8855 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8856
88572011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8858
8859 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8860
88612011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8862
8863 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8864 it's used from the C level.
8865
8866 * process.c: Use the same condition for POLL_FOR_INPUT in both
8867 keyboard.c and process.c (bug#1858).
8868
88692011-07-09 Lawrence Mitchell <wence@gmx.li>
8870
8871 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8872 (Fgnutls_boot): Use it.
8873
88742011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8875
8876 * doc.c (Fsubstitute_command_keys): Revert last change.
8877
88782011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8879
8880 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8881 quotes the next character, and doesn't affect other longer
8882 sequences (bug#8935).
8883
8884 * lread.c (syms_of_lread): Clarify that is isn't only
8885 `eval-buffer' and `eval-defun' that's affected by
8886 `lexical-binding' (bug#8460).
8887
88882011-07-15 Eli Zaretskii <eliz@gnu.org>
8889
8890 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8891 bidi redisplay when a line includes both an image and is truncated.
8892
88932011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8894
8895 Fix minor problems found by static checking.
8896 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8897 (elsz): Now a signed constant, not a size_t var. We prefer signed
8898 types to unsigned, to avoid integer comparison confusion. Without
8899 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8900 "cannot optimize loop, the loop counter may overflow", a symptom
8901 of the confusion.
8902 * indent.c (Fvertical_motion): Mark locals as initialized.
8903 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8904
89052011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8906
8907 * search.c (Fre_search_backward): Mention `case-fold-search' in
8908 all the re_search_* functions (bug#8138).
8909
8910 * keyboard.c (Fopen_dribble_file): Document when the file is
8911 closed (bug#8056).
8912
89132011-07-14 Eli Zaretskii <eliz@gnu.org>
8914
8915 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8916 bidi_cache_idx.
8917
8918 Support bidi reordering of display and overlay strings.
8919 * xdisp.c (compute_display_string_pos)
8920 (compute_display_string_end): Accept additional argument STRING.
8921 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8922 (reseat_to_string): Initialize bidi_it->string.s and
8923 bidi_it->string.schars.
8924 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8925 NULL (avoids a crash in bidi_paragraph_init).
8926 Initialize itb.string.lstring.
8927 (init_iterator): Call bidi_init_it only of a valid
8928 buffer position was specified. Initialize paragraph_embedding to
8929 L2R.
8930 (reseat_to_string): Initialize the bidi iterator.
8931 (display_string): If we need to ignore text properties of
8932 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8933 original value of -1 will not work with bidi.)
8934 (compute_display_string_pos): First arg is now struct
8935 `text_pos *'; all callers changed. Support display properties on
8936 Lisp strings.
8937 (compute_display_string_end): Support display properties on Lisp
8938 strings.
8939 (init_iterator, reseat_1, reseat_to_string): Initialize the
8940 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8941 when iterating on a string not from display properties).
8942 (compute_display_string_pos, compute_display_string_end):
8943 Fix calculation of the object to scan. Fixes an error when using
8944 arrow keys.
8945 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8946 base_level_stop; instead, set base_level_stop to BEGV.
8947 Fixes crashes in vertical-motion.
8948 (next_element_from_buffer): Improve commentary for when
8949 the iterator is before prev_stop.
8950 (init_iterator): Initialize bidi_p from the default value of
8951 bidi-display-reordering, not from buffer-local value. Use the
8952 buffer-local value only if initializing for buffer iteration.
8953 (handle_invisible_prop): Support invisible properties on strings
8954 that are being bidi-reordered.
8955 (set_iterator_to_next): Support bidi reordering of C strings and
8956 Lisp strings.
8957 (next_element_from_string): Support bidi reordering of Lisp
8958 strings.
8959 (handle_stop_backwards): Support Lisp strings as well.
8960 (display_string): Support display of R2L glyph rows.
8961 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8962 (init_iterator): Don't initialize it->bidi_p for strings
8963 here.
8964 (reseat_to_string): Initialize it->bidi_p for strings here.
8965 (next_element_from_string, next_element_from_c_string)
8966 (next_element_from_buffer): Add xassert's for correspondence
8967 between IT's object being iterated and it->bidi_it.string
8968 structure.
8969 (face_before_or_after_it_pos): Support bidi iteration.
8970 (next_element_from_c_string): Handle the case of the first string
8971 character that is not the first one in the visual order.
8972 (get_visually_first_element): New function, refactored from common
8973 parts of next_element_from_buffer, next_element_from_string, and
8974 next_element_from_c_string.
8975 (tool_bar_lines_needed, redisplay_tool_bar)
8976 (display_menu_bar): Force left-to-right direction. Add a FIXME
8977 comment for making that be controlled by a user option.
8978 (push_it, pop_it): Save and restore the state of the
8979 bidi iterator. Save and restore the bidi_p flag.
8980 (pop_it): Iterate out of display property for string iteration as
8981 well.
8982 (iterate_out_of_display_property): Support iteration over strings.
8983 (handle_single_display_spec): Set up it->bidi_it for iteration
8984 over a display string, and call bidi_init_it.
8985 (handle_single_display_spec, next_overlay_string)
8986 (get_overlay_strings_1, push_display_prop): Set up the bidi
8987 iterator for displaying display or overlay strings.
8988 (forward_to_next_line_start): Don't use the shortcut if
8989 bidi-iterating.
8990 (back_to_previous_visible_line_start): If handle_display_prop
8991 pushed the iterator stack, restore the internal state of the bidi
8992 iterator by calling bidi_pop_it same number of times.
8993 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8994 and we are bidi-iterating, don't decrement the iterator position;
8995 instead, set the first_elt flag in the bidi iterator, to produce
8996 the same effect.
8997 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8998 (push_display_prop): xassert that we are iterating a buffer.
8999 (push_it, pop_it): Save and restore paragraph_embedding member.
9000 (handle_single_display_spec, next_overlay_string)
9001 (get_overlay_strings_1, reseat_1, reseat_to_string)
9002 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9003 correctly. Don't assume unibyte strings are not bidi-reordered.
9004 (compute_display_string_pos)
9005 (compute_display_string_end): Fix handling the case of C string.
9006 (push_it, pop_it): Save and restore from_disp_prop_p.

9009 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9010 (pop_it): Call iterate_out_of_display_property only if we are
9011 popping after iteration over a string that came from a display
9012 property. Fix a typo in popping stretch info. Add an assertion
9013 for verifying that the iterator position is in sync with the bidi
9014 iterator.
9015 (handle_single_display_spec, get_overlay_strings_1)
9016 (push_display_prop): Fix initialization of paragraph direction for
9017 string when that of the parent object is not yet determined.
9018 (reseat_1): Call bidi_init_it to resync the bidi
9019 iterator with IT's position. (Bug#7616)
9020 (find_row_edges): If ROW->start.pos gives position
9021 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
9022 (handle_stop, back_to_previous_visible_line_start, reseat_1):
9023 Reset the from_disp_prop_p flag.
9024 (SAVE_IT, RESTORE_IT): New macros.
9025 (pos_visible_p, face_before_or_after_it_pos)
9026 (back_to_previous_visible_line_start)
9027 (move_it_in_display_line_to, move_it_in_display_line)
9028 (move_it_to, move_it_vertically_backward, move_it_by_lines)
9029 (try_scrolling, redisplay_window, display_line): Use them when
9030 saving a temporary copy of the iterator and restoring it back.
9031 (back_to_previous_visible_line_start, reseat_1)
9032 (init_iterator): Empty the bidi cache "stack".
9033 (move_it_in_display_line_to): If iterator ended up at
9034 EOL, but we never saw any buffer positions smaller than
9035 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9036 motion in bidi-reordered lines.
9037 (move_it_in_display_line_to): Record prev_method and prev_pos
9038 immediately before the call to set_iterator_to_next. Fixes cursor
9039 motion in bidi-reordered lines with stretch glyphs and strings
9040 displayed in margins. (Bug#8133) (Bug#8867)
9041 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9042 TO_CHARPOS.
9043 (pos_visible_p): Support positions in bidi-reordered lines.
9044 Save and restore bidi cache.
9045
9046 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9047 (bidi_paragraph_info): Delete unused struct.
9048 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9049 (bidi_cache_start): New variable.
9050 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
9051 to zero.

9468 Random fixes. E.g., (random) never returned negative values.
9469 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9470 subseconds part to the entropy, as that's a bit more random.
9471 Prefer signed to unsigned, since the signedness doesn't matter and
9472 in general we prefer signed. When given a limit, use a
9473 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9474 latter isn't right if USE_2_TAGS_FOR_INTS.
9475 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9476 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9477
94782011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9479
9480 * textprop.c (text_property_stickiness):
9481 Obey Vtext_property_default_nonsticky.
9482 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
9483 * w32fns.c (syms_of_w32fns):
9484 * xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.
9485
94862011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9487
9488 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9489 This is more efficient than Ffile_directory_p and avoids a minor race.
9490
94912011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9492
9493 * buffer.c (Foverlay_put): Say what the return value is
9494 (bug#7835).
9495
9496 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9497 is a directory before asking whether to use the file name
9498 (bug#7564).
9499 (barf_or_query_if_file_exists): Make the "File is a directory"
9500 error be more correct.
9501
9502 * fns.c (Frequire): Remove the mention of the .gz files, since
9503 that's installation-specific, but keep the mention of
9504 `get-load-suffixes'.
9505
95062011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9507
9508 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9510
95112011-07-04 Juanma Barranquero <lekktu@gmail.com>
9512
9513 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
9514 (syms_of_gnutls): Remove duplicate DEFSYM for
9515 Qgnutls_bootprop_verify_hostname_error, an error for
9516 Qgnutls_bootprop_verify_error (which is no longer used).
9517
9518 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
9519 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9520 Also (re)move comments that are misplaced or no longer relevant.
9521
95222011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9523
9524 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9602 (emacs_settings_set_property, emacs_settings_class_init)
9603 (emacs_settings_init, gsettings_obj): Remove.

9621 * eval.c (struct backtrace): Simplify and port the data structure.
9622 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9623 signed bit field, as this assumption is not portable and it makes
9624 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9625 "char debug_on_exit : 1" as this is not portable either; instead,
9626 use the portable "unsigned int debug_on_exit : 1". Remove unused
9627 member evalargs. Remove obsolete comments about cc bombing out.
9628
96292011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9663 * makefile.w32-in: Redesign dependencies so they reflect more
9664 clearly which files are directly included by each source file,
9665 and not through other includes.
9666

9668
9669 * buffer.c (Qclone_number): Declare static and DEFSYM it.
9670 (sort_overlays, overlay_strings): When an overlay's clone number
9671 matches the window's clone number process the overlay even if
9672 the overlay's window property doesn't match the current window.
9673
9674 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
9675 (Fwindow_hchild): Rename to Fwindow_left_child.
9676 (Fwindow_next): Rename to Fwindow_next_sibling.

9700 frames size_hint to set minimum and natural (Bug#8919).
9701 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
9702 and use min_width/height from frames size_hint to set
9703 min_width/height (Bug#8919).
9704
9705 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
9706 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

9710
9711 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
9712 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

9815 to improve quality of diagnostics for out-of-range radices.
9816 Calculate buffer size correctly for out-of-range radices.
9817 (read1): Check for integer overflow in radices, and in
9818 read-circle numbers.
9819 (read_escape): Avoid int overflow.
9820 (Fload, openp, read_buffer_size, read1)
9821 (substitute_object_recurse, read_vector, read_list, map_obarray):
9822 Use ptrdiff_t, not int, for sizes.

98422011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9843
9844 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9845 The following patches are for when GLYPH_DEBUG && !XASSERT.
9846 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9847 * dispnew.c (flush_stdout):
9848 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9849 Mark as externally visible.
9850 * dispnew.c (check_window_matrix_pointers): Now static.
9851 * dispnew.c (window_to_frame_vpos):
9852 * xfns.c (unwind_create_frame):
9853 * xterm.c (x_check_font): Remove unused local.
9854 * scroll.c (CHECK_BOUNDS):
9855 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9856 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9857 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9858 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9859 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9860 Now static.
9861 (debug_method_add): Use va_list and vsprintf rather than relying
9862 on undefined behavior with wrong number of arguments.
9863 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9864 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9865 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9866 since we're not interested in debugging glyphs with old libraries.
9867 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9868 GCC 4.6.0's static checking.
9869
98702011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9871

9885 (.bitmaps_last):
9886 * xfaces.c (load_pixmap):
9887 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9888 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9889 (.bitmaps_last, struct x_output.icon_bitmap):
9890 Use ptrdiff_t, not int, for bitmap indexes.
9891 (x_allocate_bitmap_record): Check for size overflow.
9892 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9893
9894 Use ptrdiff_t, not int, for overlay counts.
9895 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9896 * editfns.c (overlays_around, get_pos_property):
9897 * textprop.c (get_char_property_and_overlay):
9898 * xdisp.c (next_overlay_change, note_mouse_highlight):
9899 * xfaces.c (face_at_buffer_position):
9900 * buffer.c (OVERLAY_COUNT_MAX): New macro.

9902 (Fnext_overlay_change, Fprevious_overlay_change)
9903 (mouse_face_overlay_overlaps, Foverlays_in):
9904 Use ptrdiff_t, not int, for sizes.
9905 (overlays_at, overlays_in): Check for size-calculation overflow.
9906
9907 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9908
9909 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9910 (x_session_initialize): Do not assume string length fits in int.
9911
9912 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9913 This is unlikely, but can occur if DPI is outlandish.
9914
9915 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9916 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9917
9918 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9919 * xrdb.c (magic_file_p, search_magic_path):
9920 Omit last arg SUFFIX; it was always 0. All callers changed.
9921 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9922
9923 * xfont.c (xfont_match): Avoid need for strlen.
9924
9925 * xfns.c: Don't assume strlen fits in int.
9926 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9927
9928 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9929 not unsigned long, as we prefer signed integers. All callers changed.
9930 Detect integer overflow in repeat count.
9931 (message_dolog): Don't assume print length fits in 39 bytes.
9932 (display_mode_element): Don't assume strlen fits in int.
9933
9934 * termcap.c: Don't assume sizes fit in int and never overflow.
9935 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9936 (gobble_line): Check for size-calculation overflow.
9937
9938 * minibuf.c (Fread_buffer):
9939 * lread.c (intern, intern_c_string):
9940 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9941 Don't assume string length fits in int.
9942
9943 * keyboard.c (parse_tool_bar_item):
9944 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9945
9946 * font.c: Don't assume string length fits in int.
9947 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9948 Use ptrdiff_t, not int.
9949 (font_intern_prop): Don't assume string length fits in int.
9950 Don't assume integer property fits in fixnum.
9951 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9952
9953 * filelock.c: Fix some buffer overrun and integer overflow issues.
9954 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9955 Reformulate so as not to need the command string.
9956 Invoke gzip -cd rather than gunzip, as it's more portable.
9957 (lock_info_type, lock_file_1, lock_file):
9958 Don't assume pid_t and time_t fit in unsigned long.
9959 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9960 (current_lock_owner): Prefer signed type for sizes.
9961 Use memcpy, not strncpy, where memcpy is what is really wanted.
9962 Don't assume (via atoi) that time_t and pid_t fit in int.
9963 Check for time_t and/or pid_t out of range, e.g., via a network share.
9964 Don't alloca where an auto var works fine.
9965
9966 * fileio.c: Fix some integer overflow issues.
9967 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9968 Don't assume string length fits in int.
9969 (directory_file_name): Don't assume string length fits in long.
9970 (make_temp_name): Don't assume pid fits in int, or that its print
9971 length is less than 20.
9972
9973 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9974
9975 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9976
9977 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9978
9979 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9980 We prefer signed integers, even for size calculations.
9981
9982 * emacs.c: Don't assume string length fits in 'int'.
9983 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9984 (main): Don't invoke strlen when not needed.
9985
9986 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9987 (XD_DEBUG_MESSAGE): Don't waste a byte.
9988
9989 * callproc.c (getenv_internal_1, getenv_internal)
9990 (Fgetenv_internal):
9991 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9992
9993 * lread.c (invalid_syntax): Omit length argument.
9994 All uses changed. This doesn't fix a bug, but it simplifies the
9995 code away from its former Hollerith-constant appearance, and it's
9996 one less 'int' to worry about when looking at integer-overflow issues.
9997 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9998
9999 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10000 This didn't break anything, but it didn't help either.
10001 It's confusing to put a bogus integer in a place where the actual
10002 value does not matter.
10003 (LIST_END_P): Remove unused macro and its bogus comment.
10004 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10005
10006 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10007 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10008 implementation.
10009 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10010 We prefer signed types, and the value cannot exceed the EMACS_INT
10011 range anyway (because otherwise the length would not be representable).
10012 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10013 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10014 This avoids a GCC warning when WIDE_EMACS_INT.
10015
10016 * indent.c (sane_tab_width): New function.
10017 (current_column, scan_for_column, Findent_to, position_indentation)
10018 (compute_motion): Use it. This is just for clarity.
10019 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10020
10021 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10022
10023 * lisp.h (lint_assume): New macro.
10024 * composite.c (composition_gstring_put_cache):
10025 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10026
10027 * editfns.c, insdel.c:
10028 Omit unnecessary forward decls, to simplify future changes.
10029
10030 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10031
10032 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10033
10034 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10035 Use much-faster test for byte-length change.
10036 Don't assume string byte-length fits in 'int'.
10037 Check that character arg fits in 'int'.
10038 (mapcar1): Declare byte as byte, for clarity.
10039
10040 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10041
10042 * fns.c (concat): Catch string overflow earlier.
10043 Do not rely on integer wraparound.
10044
10045 * dispextern.h (struct it.overlay_strings_charpos)
10046 (struct it.selective): Now EMACS_INT, not int.
10047 * xdisp.c (forward_to_next_line_start)
10048 (back_to_previous_visible_line_start)
10049 (reseat_at_next_visible_line_start, next_element_from_buffer):
10050 Don't arbitrarily truncate the value of 'selective' to int.
10051
10052 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10053
10054 * composite.c: Don't truncate sizes to 'int'.
10055 (composition_gstring_p, composition_reseat_it)
10056 (composition_adjust_point): Use EMACS_INT, not int.
10057 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10058 not EMACS_UINT, for indexes.
10059
10060 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10061
10062 * buffer.c: Include <verify.h>.
10063 (struct sortvec.priority, struct sortstr.priority):
10064 Now EMACS_INT, not int.
10065 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10066 (struct sortstr.size, record_overlay_string)
10067 (struct sortstrlist.size, struct sortlist.used):
10068 Don't truncate size to int.
10069 (record_overlay_string): Check for size-calculation overflow.
10070 (init_buffer_once): Check at compile-time, not run-time.
10071
100722011-06-22 Jim Meyering <meyering@redhat.com>
10073
10074 Don't leak an XBM-image-sized buffer
10075 * image.c (xbm_load): Free the image buffer after using it.
10076
100772011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10078
10079 Port to Sun C.
10080 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10081 that Sun C diagnosed.
10082 * fns.c (secure_hash): Fix pointer signedness issue.
10083 * intervals.c (static_offset_intervals): New function.
10084 (offset_intervals): Use it.
10085
100862011-06-21 Leo Liu <sdl.web@gmail.com>
10087
10088 * deps.mk (fns.o):
10089 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10090 sha512.h.
10091
10092 * fns.c (secure_hash): Rename from crypto_hash_function and change
10093 the first arg to accept symbols.
10094 (Fsecure_hash): New primitive.
10095 (syms_of_fns): New symbols.
10096
100972011-06-20 Deniz Dogan <deniz@dogan.se>
10098
10099 * process.c (Fset_process_buffer): Clarify return value in
10100 docstring.
10101
101022011-06-18 Chong Yidong <cyd@stupidchicken.com>
10103
10104 * dispnew.c (add_window_display_history): Use BVAR.
10105
10106 * xdisp.c (debug_method_add): Use BVAR.
10107 (check_window_end, dump_glyph_matrix, dump_glyph)
10108 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10109
10110 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10111 Likewise.
10112
10113 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10114 check till after the cache is created in init_frame_faces.
10115
101162011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10117
10118 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10119
101202011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10121
10122 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10123 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10124 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10125
10126 Improve buffer-overflow checking (Bug#8873).
10127 * fileio.c (Finsert_file_contents):
10128 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10129 Remove the old (too-loose) buffer overflow checks.
10130 They weren't needed, since make_gap checks for buffer overflow.
10131 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10132 The old code merely checked for Emacs fixnum overflow, and relied
10133 on undefined (wraparound) behavior. The new code avoids undefined
10134 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10135
10136 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10137 Tune. Don't use wider integers than needed. Don't use alloca.
10138 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10139
10140 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10141
10142 * insdel.c, lisp.h (buffer_overflow): New function.
10143 (insert_from_buffer_1, replace_range, replace_range_2):
10144 * insdel.c (make_gap_larger):
10145 * editfns.c (Finsert_char):
10146 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10147
10148 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10149
101502011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10151
10152 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10153
10154 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10155 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10156
10157 * fileio.c: Don't assume EMACS_INT fits in off_t.
10158 (emacs_lseek): New static function.
10159 (Finsert_file_contents, Fwrite_region): Use it.
10160 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10161
10162 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10163
10164 * fns.c: Don't overflow int when computing a list length.
10165 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10166 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10167 truncation on 64-bit hosts. Check for QUIT every
10168 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10169 faster and is responsive enough.
10170 (Flength): Report an error instead of overflowing an integer.
10171 (Fsafe_length): Return a float if the value is not representable
10172 as a fixnum. This shouldn't happen except in contrived situations.
10173 (Fnthcdr, Fsort): Don't assume list length fits in int.
10174 (Fcopy_sequence): Don't assume vector length fits in int.
10175
10176 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10177 (header_size, word_size): New constants.
10178 (allocate_vectorlike): Don't check size overflow here.
10179 (allocate_vector): Check it here instead, since this is the only
10180 caller of allocate_vectorlike that could cause overflow.
10181 Check that the new vector's length is representable as a fixnum.
10182
10183 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10184 The previous code was bogus. For example, next_almost_prime (32)
10185 returned 39, which is undesirable as it is a multiple of 3; and
10186 next_almost_prime (24) returned 25, which is a multiple of 5 so
10187 why was the code bothering to check for multiples of 7?
10188
10189 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10190
10191 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10192
10193 Variadic C functions now count arguments with ptrdiff_t.
10194 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10195 Back then I didn't know that the Emacs coding style prefers signed int.
10196 Also, in the meantime I found a few more instances where arguments
10197 were being counted with int, which may truncate counts on 64-bit
10198 machines, or EMACS_INT, which may be unnecessarily wide.
10199 * lisp.h (struct Lisp_Subr.function.aMANY)
10200 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10201 Arg counts are now ptrdiff_t, not size_t.
10202 All variadic functions and their callers changed accordingly.
10203 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10204 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10205 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10206 * callint.c (Fcall_interactively): Check arg count for overflow,
10207 to avoid potential buffer overrun. Use signed char, not 'int',
10208 for 'varies' array, so that we needn't bother to check its size
10209 calculation for overflow.
10210 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10211 * eval.c (apply_lambda):
10212 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10213 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10214 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10215
10216 * callint.c (Fcall_interactively): Don't use index var as event count.
10217
10218 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10219 * mem-limits.h (SIZE): Remove; no longer used.
10220
10221 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10222
10223 Remove unnecessary casts.
10224 * xterm.c (x_term_init):
10225 * xfns.c (x_set_border_pixel):
10226 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10227 These aren't needed now that we assume ANSI C.
10228
10229 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10230 It's more likely to cause problems (due to unsigned overflow)
10231 than to cure them.
10232
10233 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10234
10235 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10236
10237 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10238
10239 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10240
10241 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10242
10243 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10244
10245 GLYPH_CODE_FACE returns EMACS_INT, not int.
10246 * dispextern.h (merge_faces):
10247 * xfaces.c (merge_faces):
10248 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10249 Don't assume EMACS_INT fits in int.
10250
10251 * character.h (CHAR_VALID_P): Remove unused parameter.
10252 * fontset.c, lisp.h, xdisp.c: All uses changed.
10253
10254 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10255
10256 * fns.c (concat): Minor tuning based on overflow analysis.
10257 This doesn't fix any bugs. Use int to hold character, instead
10258 of constantly refetching from Emacs object. Use XFASTINT, not
10259 XINT, for value known to be a character. Don't bother comparing
10260 a single byte to 0400, as it's always less.
10261
10262 * floatfns.c (Fexpt):
10263 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10264
10265 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10266 for characters.
10267
10268 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10269
10270 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10271 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10272 incorrectly succeed when S was a string, because 4294967386 was
10273 truncated before it was used.
10274
10275 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10276 Otherwise, an out-of-range integer could cause undefined behavior
10277 on a 64-bit host.
10278
10279 * composite.c: Use int, not EMACS_INT, for characters.
10280 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10281 EMACS_INT, for values that are known to be in character range.
10282 This doesn't fix any bugs but is the usual style inside Emacs and
10283 may generate better code on 32-bit machines.
10284
10285 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10286 This is for reasons similar to the recent CHAR_STRING fix.
10287 * charset.c (Fencode_char): Check that character arg is actually
10288 a character. Pass an int to ENCODE_CHAR.
10289 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10290 wider than 'int', as a compile-time check to prevent future regressions
10291 in this area.
10292
10293 * character.c (char_string): Remove unnecessary casts.
10294
10295 Make sure a 64-bit char is never passed to CHAR_STRING.
10296 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10297 by silently ignoring the top 32 bits, allowing some values
10298 that were far too large to be valid characters.
10299 * character.h: Include <verify.h>.
10300 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10301 arguments are no wider than unsigned, as a compile-time check
10302 to prevent future regressions in this area.
10303 * data.c (Faset):
10304 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10305 (Fsubst_char_in_region):
10306 * fns.c (concat):
10307 * xdisp.c (decode_mode_spec_coding):
10308 Adjust to CHAR_STRING's new requirement.
10309 * editfns.c (Finsert_char, Fsubst_char_in_region):
10310 * fns.c (concat): Check that character args are actually
10311 characters. Without this test, these functions did the wrong
10312 thing with wildly out-of-range values on 64-bit hosts.
10313
10314 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10315 These casts should not be needed on 32-bit hosts, either.
10316 * keyboard.c (read_char):
10317 * lread.c (Fload): Remove casts to unsigned.
10318
10319 * lisp.h (UNSIGNED_CMP): New macro.
10320 This fixes comparison bugs on 64-bit hosts.
10321 (ASCII_CHAR_P): Use it.
10322 * casefiddle.c (casify_object):
10323 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10324 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10325 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10326 * dispextern.h (FACE_FROM_ID):
10327 * keyboard.c (read_char): Use UNSIGNED_CMP.
10328
10329 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10330 not to EMACS_INT, to avoid GCC warning.
10331
10332 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10333
10334 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10335 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10336 isn't needed on 32-bit machines.
10337
10338 * buffer.c (Fgenerate_new_buffer_name):
10339 Use EMACS_INT for count, not int.
10340 (advance_to_char_boundary): Return EMACS_INT, not int.
10341
10342 * data.c (Qcompiled_function): Now static.
10343
10344 * window.c (window_body_lines): Now static.
10345
10346 * image.c (gif_load): Rename local to avoid shadowing.
10347
10348 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10349 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10350 * alloc.c (make_save_value): Integer argument is now of type
10351 ptrdiff_t, not int.
10352 (mark_object): Use ptrdiff_t, not int.
10353 * lisp.h (pD): New macro.
10354 * print.c (print_object): Use it.
10355
10356 * alloc.c: Use EMACS_INT, not int, to count objects.
10357 (total_conses, total_markers, total_symbols, total_vector_size)
10358 (total_free_conses, total_free_markers, total_free_symbols)
10359 (total_free_floats, total_floats, total_free_intervals)
10360 (total_intervals, total_strings, total_free_strings):
10361 Now EMACS_INT, not int. All uses changed.
10362 (Fgarbage_collect): Compute overall total using a double, so that
10363 integer overflow is less likely to be a problem. Check for overflow
10364 when converting back to an integer.
10365 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10366 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10367 These were 'int' variables that could overflow on 64-bit hosts;
10368 they were never used, so remove them instead of repairing them.
10369 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10370 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10371 Previously, this ceilinged at INT_MAX, but that doesn't work on
10372 64-bit machines.
10373 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10374
10375 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10376 (allocate_vectorlike): Check for ptrdiff_t overflow.
10377 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10378 when a (possibly-narrower) signed value would do just as well.
10379 We prefer using signed arithmetic, to avoid comparison confusion.
10380
10381 * alloc.c: Catch some string size overflows that we were missing.
10382 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10383 for convenience in STRING_BYTES_MAX.
10384 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10385 The definition here is exact; the one in lisp.h was approximate.
10386 (allocate_string_data): Check for string overflow. This catches
10387 some instances we weren't catching before. Also, it catches
10388 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10389 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10390 and ptrdiff_t and EMACS_INT are both 64 bits.
10391
10392 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10393 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10394 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10395
10396 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10397
10398 * alloc.c (Fmake_string): Check for out-of-range init.
10399

10401
10402 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10403

10422 (xg_initialize): Call update_theme_scrollbar_width.
10423
10424 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10425
10426 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10427
104282011-06-12 Martin Rudalics <rudalics@gmx.at>
10429
10430 * frame.c (make_frame): Call other_buffer_safely instead of
10431 other_buffer.
10432

10897
10898 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).

10964 (bidi_level_of_next_char): Call bidi_fetch_char and
10965 bidi_fetch_char_advance instead of FETCH_CHAR and

10971 instead of using explicit *_CHAR codes.
10972 (bidi_resolve_explicit, bidi_resolve_weak):
10973 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10974 bidirectional text is supported only in multibyte buffers.

10983 were just reseat()'ed to a new position.
10984
10985 * xdisp.c (set_cursor_from_row): Set start and stop points
10986 according to the row's direction when priming the loop that looks
10987 for the glyph on which to display cursor.
10988 (single_display_spec_intangible_p): Function deleted.
10989 (display_prop_intangible_p): Reimplement to call
10990 handle_display_spec instead of single_display_spec_intangible_p.
10991 Accept 3 additional arguments needed by handle_display_spec.
10992 This fixes incorrect cursor motion across display property with complex
10993 values: lists, `(when COND...)' forms, etc.
10994 (single_display_spec_string_p): Support property values that are
10995 lists with the argument STRING its top-level element.
10996 (display_prop_string_p): Fix the condition for processing a
10997 property that is a list to be consistent with handle_display_spec.

11007 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11008 frame_window_p members of struct bidi_it.

11014
11015 * keyboard.c (adjust_point_for_property): Adjust the call to
11016 display_prop_intangible_p to its new signature.
11017
11018 * dispextern.h (struct bidi_it): New member frame_window_p.

11033
11034 * gnutls.c: Use Emacs's memory allocators.
11035 Without this change, the gnutls library would invoke malloc etc.
11036 directly, which causes problems on non-SYNC_INPUT hosts, and which
11037 runs afoul of improving memory_full behavior. (Bug#8761)
11038 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11039 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11040 xfree instead of the default malloc, realloc, free.
11041 (Fgnutls_boot): No need to check for memory allocation failure,
11042 since xmalloc does that for us.

11060 * image.c (make_image, search_image_cache, lookup_image)
11061 (xpm_put_color_table_h):
11062 * lisp.h (struct Lisp_Hash_Table):
11063 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11064 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11065 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11066 * alloc.c (allocate_vectorlike):
11067 Check for overflow in vector size calculations.
11068 * ccl.c (ccl_driver):
11069 Check for overflow when converting EMACS_INT to int.
11070 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11071 need to be updated by these changes.
11072 * fns.c (make_hash_table, maybe_resize_hash_table):
11073 Check for integer overflow with large hash tables.
11074 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11075 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11076 (SXHASH_REDUCE): New macro.
11077 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11078 Use it instead of discarding useful hash info with large hash values.
11079 (sxhash_float): New function.
11080 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11081 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11082 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11083 Rewrite to use FIXNUM_BITS, as this simplifies things.
11084 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11085 Adjust signatures to match updated version of code.
11086 (consing_since_gc): Now EMACS_INT, since a single hash table can
11087 use more than INT_MAX bytes.
11088

11135
11136 Make it possible to run ./temacs.
11137
11138 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11139 syms_of_callproc does the same thing. Remove test for
11140 "initialized", do it in the caller.
11141 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11142
111432011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11144
11145 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11146 (read_minibuf): Use get_minibuffer.

11148 (Qmetadata): New var.
11149 * data.c (Qbuffer): Don't make it static.
11150 (syms_of_data): Use DEFSYM.
11151
111522011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11153
11154 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11155 (CCL_CODE_MIN): New macro.
11156
111572011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11158
11159 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11160
11161 * eval.c (Qdebug): Now static.
11162 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11163 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11164 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11165
111662011-05-29 Chong Yidong <cyd@stupidchicken.com>
11167
11168 * image.c: Various fixes to ImageMagick code comments.
11169 (Fimagemagick_types): Doc fix.
11170
111712011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11172
11173 Minor fixes prompted by GCC 4.6.0 warnings.
11174
11175 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11176
11177 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11178 (x_clipboard_manager_save_all): Move extern decl to ...
11179 * xterm.h: ... here, so that it can be checked for consistency.
11180
111812011-05-29 Chong Yidong <cyd@stupidchicken.com>
11182
11183 * xselect.c (x_clipboard_manager_save_frame)
11184 (x_clipboard_manager_save_all): New functions.
11185 (Fx_clipboard_manager_save): Lisp function deleted.
11186
11187 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11188 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11189

11191
111922011-05-28 William Xu <william.xwl@gmail.com>
11193

11195 exiting (Bug#8239).
11196
111972011-05-28 Jim Meyering <meyering@redhat.com>
11198
11199 Avoid a sign-extension bug in crypto_hash_function.
11200 * fns.c (to_uchar): Define.
11201 (crypto_hash_function): Use it to convert some newly-signed
11202 variables to unsigned, to avoid sign-extension bugs. For example,
11203 without this change, (md5 "truc") would evaluate to
11204 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11205 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11206 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11207
112082011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11209
11210 Integer overflow fixes.
11211
11212 * dbusbind.c: Serial number integer overflow fixes.
11213 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11214 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11215 to hold a serial number that is too large for a fixnum.
11216 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11217 Check for serial numbers out of range. Decode any serial number
11218 that was so large that it became a float. (Bug#8722)
11219
11220 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11221 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11222 Use XFASTINT rather than XUINT when numbers are nonnegative.
11223 (xd_append_arg, Fdbus_method_return_internal):
11224 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11225 arguments, check that Lisp number is nonnegative, rather than
11226 silently wrapping negative numbers around. (Bug#8722)
11227 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11228 (Bug#8722)
11229
11230 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11231
11232 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11233
11234 ccl: Add integer overflow checks.
11235 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11236 (IN_INT_RANGE): New macros.
11237 (ccl_driver): Use them to check for integer overflow when
11238 decoding a CCL program. Many of the new checks are whether XINT (x)
11239 fits in int; it doesn't always, on 64-bit hosts. The new version
11240 doesn't catch all possible integer overflows, but it's an
11241 improvement. (Bug#8719)
11242
11243 * alloc.c (make_event_array): Use XINT, not XUINT.
11244 There's no need for unsigned here.
11245
11246 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11247 This follows up to the 2011-05-06 change that substituted uintptr_t
11248 for EMACS_INT. This case wasn't caught back then.
11249
11250 Rework Fformat to avoid integer overflow issues.
11251 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11252 now (part of C89). Include <verify.h>.
11253 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11254 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11255 (Fformat): Avoid the prepass trying to compute sizes; it was only
11256 approximate and thus did not catch overflow reliably. Instead, walk
11257 through the format just once, formatting and computing sizes as we go,
11258 checking for integer overflow at every step, and allocating a larger
11259 buffer as needed. Keep track separately whether the format is
11260 multibyte. Keep only the most-recently calculated precision, rather
11261 than them all. Record whether each argument has been converted to
11262 string. Use EMACS_INT, not int, for byte and char and arg counts.
11263 Support field widths and precisions larger than INT_MAX. Avoid
11264 sprintf's undefined behavior with conversion specifications such as %#d
11265 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11266 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11267 formatting out-of-range floating point numbers with int
11268 formats. (Bug#8668)
11269
11270 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11271
11272 * data.c: Avoid integer truncation in expressions involving floats.
11273 * data.c: Include <intprops.h>.
11274 (arith_driver): When there's an integer overflow in an expression
11275 involving floating point, convert the integers to floating point
11276 so that the resulting value does not suffer from catastrophic
11277 integer truncation. For example, on a 64-bit host (* 4
11278 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11279 Do not rely on undefined behavior after integer overflow.
11280
11281 merge count_size_as_multibyte, parse_str_to_multibyte
11282 * character.c, character.h (count_size_as_multibyte):
11283 Rename from parse_str_to_multibyte; all uses changed.
11284 Check for integer overflow.
11285 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11286 since it's now a duplicate of the other. This is more of
11287 a character than a buffer op, so better that it's in character.c.
11288 * fns.c, print.c: Adjust to above changes.
11289
112902011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11291
11292 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11293
112942011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11295
11296 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11297 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11298 (x_clipboard_manager_save): Now static.
11299 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11300
11301 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11302 (crypto_hash_function): Now static.
11303 Fix pointer signedness problems. Avoid unnecessary initializations.
11304
113052011-05-27 Chong Yidong <cyd@stupidchicken.com>
11306
11307 * termhooks.h (Vselection_alist): Make it terminal-local.
11308
11309 * terminal.c (create_terminal): Initialize it.
11310
11311 * xselect.c: Support for clipboard managers.

11317 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11318 (x_own_selection, x_get_local_selection, x_convert_selection):
11319 New arg, specifying work frame. Use terminal-local Vselection_alist.
11320 (some_frame_on_display): Delete unused function.
11321 (Fx_own_selection_internal, Fx_get_selection_internal)
11322 (Fx_disown_selection_internal, Fx_selection_owner_p)
11323 (Fx_selection_exists_p): New optional frame arg.
11324 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11325 (x_handle_selection_clear): Don't treat other terminals with the
11326 same keyboard specially. Use the terminal-local Vselection_alist.
11327 (x_clear_frame_selections): Use Frun_hook_with_args.
11328
11329 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11330
11331 * xterm.h: Add support for those atoms.
11332
113332011-05-26 Chong Yidong <cyd@stupidchicken.com>
11334
11335 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11336 (converted_selections, conversion_fail_tag): New global variables.
11337 (x_selection_request_lisp_error): Free the above.
11338 (x_get_local_selection): Remove unnecessary code.
11339 (x_reply_selection_request): Args changed; handle arbitrary array
11340 of converted selections stored in converted_selections.
11341 Separate the XChangeProperty and SelectionNotify steps.
11342 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11343 (x_convert_selection): New function.
11344 (x_handle_selection_event): Simplify.
11345 (x_get_foreign_selection): Don't ignore incoming requests while
11346 waiting for an answer; this will fail when we implement
11347 SAVE_TARGETS, and seems unnecessary anyway.
11348 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11349 (Vx_sent_selection_functions): Doc fix.
11350
113512011-05-26 Leo Liu <sdl.web@gmail.com>
11352
11353 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)

11365 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11366 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11367 row. Mark glyph row for fringe update if periodicity changed.

11391 Remove macros that are defined and never used.
11392 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

11426
11427 * systime.h (Time): Define only if emacs is defined.
11428 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11429 where the include path doesn't have X11/X.h by default. See
11430 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

11447 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11448 (lisp): Set the order to that of loadup.el.
11449 (shortlisp): Make it a copy of $lisp.
11450 (SOME_MACHINE_LISP): Remove.
11451 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.

11470
11471 Fix some integer overflow issues, such as string length overflow.
11472
11473 * insdel.c (count_size_as_multibyte): Check for string overflow.
11474
11475 * character.c (lisp_string_width): Check for string overflow.
11476 Use EMACS_INT, not int, for string indexes and lengths; in
11477 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11478 the resulting string length overflows an EMACS_INT; instead,
11479 report a string overflow if no precision given. When checking for
11480 precision exhaustion, use a check that cannot possibly have
11481 integer overflow. (Bug#8675)
11482 * character.h (lisp_string_width): Adjust to new signature.
11483
11484 * alloc.c (string_overflow): New function.
11485 (Fmake_string): Use it. This doesn't change behavior, but saves
11486 a few bytes and will simplify future changes.
11487 * character.c (string_escape_byte8): Likewise.
11488 * lisp.h (string_overflow): New decl.
11489
11490 Fixups, following up to the user-interface timestamp change.
11491 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11492 for UI timestamps, instead of unsigned long.
11493 * msdos.c (mouse_get_pos): Likewise.
11494 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11495 * w32gui.h (Time): Define by including "systime.h" rather than by
11496 declaring it ourselves. (Bug#8664)
11497
11498 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11499 * image.c (clear_image_cache): Likewise.
11500
11501 * term.c (term_mouse_position): Don't assume time_t wraparound.
11502
11503 Be more systematic about user-interface timestamps.
11504 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11505 and sometimes 'EMACS_UINT', to represent these timestamps.
11506 This change causes it to use 'Time' uniformly, as that's what X uses.
11507 This makes the code easier to follow, and makes it easier to catch
11508 integer overflow bugs such as Bug#8664.
11509 * frame.c (Fmouse_position, Fmouse_pixel_position):
11510 Use Time, not unsigned long, for user-interface timestamps.
11511 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11512 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11513 * keyboard.h (last_event_timestamp): Likewise.
11514 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11515 * menu.h (xmenu_show): Likewise.
11516 * term.c (term_mouse_position): Likewise.
11517 * termhooks.h (struct input_event.timestamp): Likewise.
11518 (struct terminal.mouse_position_hook): Likewise.
11519 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11520 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11521 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11522 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11523 what it was before.
11524 * menu.h, termhooks.h: Include "systime.h", for Time.
11525
11526 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11527 Don't assume that the difference between two unsigned long values
11528 can fit into an integer. At this point, we know button_down_time
11529 <= event->timestamp, so the difference must be nonnegative, so
11530 there's no need to cast the result if double-click-time is
11531 nonnegative, as it should be; check that it's nonnegative, just in
11532 case. This bug is triggered when events are more than 2**31 ms
11533 apart (about 25 days). (Bug#8664)
11534
11535 * xselect.c (last_event_timestamp): Remove duplicate decl.
11536 (x_own_selection): Remove needless cast to unsigned long.
11537
11538 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11539 that always fit in int. Use a sentinel instead of a counter, to
11540 avoid a temp and to allay GCC's concerns about possible int overflow.
11541 * frame.h (struct frame): Use int for menu_bar_items_used
11542 instead of EMACS_INT, since it always fits in int.
11543
11544 * menu.c (grow_menu_items): Check for int overflow.
11545
11546 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11547
11548 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11549 Before, the code was not consistent. These values cannot exceed
11550 2**31 - 1 so there's no need to make them unsigned.
11551 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11552 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11553 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11554 as modifiers.
11555 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11556
11557 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11558 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11559 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11560 presumably because the widths might not match.
11561
11562 * window.c (size_window): Avoid needless test at loop start.
11563
115642011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11565
11566 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11567
115682011-05-12 Drew Adams <drew.adams@oracle.com>
11569
11570 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11571
115722011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11573
11574 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11575 `width' to `bar_area_x' and `bar_area_width', respectively.
11576 (x_scroll_run): Take account of fringe background extension.
11577
11578 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11579 Rename local vars `left' and `width' to `bar_area_x' and
11580 `bar_area_width', respectively.
11581 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11582 background extension.
11583
115842011-05-10 Jim Meyering <meyering@redhat.com>
11585
11586 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11587
115882011-05-10 Juanma Barranquero <lekktu@gmail.com>
11589
11590 * image.c (Finit_image_library): Return t for built-in image types,
11591 like pbm and xbm. (Bug#8640)
11592
115932011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11594
11595 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11596
115972011-05-07 Eli Zaretskii <eliz@gnu.org>
11598
11599 * w32console.c (Fset_screen_color): Doc fix.
11600 (Fget_screen_color): New function.
11601 (syms_of_ntterm): Defsubr it.
11602
11603 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11604 unlink the temporary file if Fcall_process didn't create it in the
11605 first place.
11606 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11607 child process will be redirected to a file specified with `:file'.
11608 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11609 cue to call_process_cleanup not to close that handle.
11610
116112011-05-07 Ben Key <bkey76@gmail.com>
11612
11613 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11614 one of two shell specific rules, either bootstrap-temacs-CMD or
11615 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11616 to the previous implementation of the bootstrap-temacs rule.
11617 The bootstrap-temacs-CMD rule is similar to the previous
11618 implementation of the bootstrap-temacs rule except that it
11619 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11620 variable.
11621
11622 These changes, along with some changes to nt/configure.bat,
11623 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11624 earlier fix to add support for --cflags and --ldflags options
11625 that include quotes so that it works whether make uses cmd or
11626 sh as the shell.
11627
116282011-05-06 Michael Albinus <michael.albinus@gmx.de>
11629
11630 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11631 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11632 is a constant.
11633 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11634 a string. Handle both cases.
11635 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11636 (Fdbus_register_method): Use Qinvalid_function.
11637
116382011-05-06 Juanma Barranquero <lekktu@gmail.com>
11639
11640 * makefile.w32-in: Update dependencies.
11641 (LISP_H): Add inttypes.h and stdin.h.
11642 (PROCESS_H): Add unistd.h.
11643
116442011-05-06 Eli Zaretskii <eliz@gnu.org>
11645
11646 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11647 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11648
116492011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11650
11651 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11652
11653 * term.c (vfatal): Remove stray call to va_end.
11654 It's not needed and the C Standard doesn't allow it here anyway.
11655
11656 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11657 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11658
11659 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11660 bytes.
11661
11662 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11663
11664 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11665
11666 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11667
11668 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11669
11670 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11671
11672 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11673 * charset.c (Fdefine_charset_internal): Don't initialize
11674 charset.code_space[15]. The value was garbage, on hosts with
11675 32-bit int (Bug#8600).
11676
11677 * lread.c (read_integer): Be more consistent with string-to-number.
11678 Use string_to_number to do the actual conversion; this avoids
11679 rounding errors and fixes some other screwups. Without this fix,
11680 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11681 (digit_to_number): Move earlier, for benefit of read_integer.
11682 Return -1 if the digit is out of range for the base, -2 if it is
11683 not a digit in any supported base. (Bug#8602)
11684
11685 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11686
11687 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11688 to match comment at start of function. This also removes a
11689 GCC warning about overflow in a 32+64-bit port.
11690
11691 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11692
11693 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11694 Reported by Stefan Monnier in
11695 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11696 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11697 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11698
11699 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11700 (EMACS_UINTPTR): Likewise, with uintptr_t.
11701
11702 * lisp.h: Prefer 64-bit EMACS_INT if available.
11703 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11704 on 32-bit hosts that have 64-bit int, so that they can access
11705 large files.
11706 However, temporarily disable this change unless the temporary
11707 symbol WIDE_EMACS_INT is defined.
11708
11709 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11710
11711 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11712 This removes an assumption that EMACS_INT and long are the same
11713 width as pointers. The assumption is true for Emacs porting targets
11714 now, but we want to make other targets possible.
11715 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11716 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11717 In the rest of the code, change types of integers that hold casted
11718 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11719 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11720 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11721 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11722 No need to cast type when ORing.
11723 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11724 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11725 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11726 assume EMACS_INT is the same width as char *.
11727 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11728 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11729 Remove no-longer-needed casts.
11730 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11731 (xg_tool_bar_help_callback, xg_make_tool_item):
11732 Use EMACS_INTPTR to hold an integer
11733 that will be cast to void *; this can avoid a GCC warning
11734 if EMACS_INT is not the same width as void *.
11735 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11736 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11737 (current_message_1, set_message_1):
11738 Use a local to convert to proper width without a cast.
11739 * xmenu.c (dialog_selection_callback): Likewise.
11740
11741 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11742 Also, don't assume VALBITS / RAND_BITS is less than 5,
11743 and don't rely on undefined behavior when shifting a 1 left into
11744 the sign bit.
11745 * lisp.h (get_random): Change signature to match.
11746
11747 * lread.c (hash_string): Use size_t, not int, for hash computation.
11748 Normally we prefer signed values; but hashing is special, because
11749 it's better to use unsigned division on hash table sizes so that
11750 the remainder is nonnegative. Also, size_t is the natural width
11751 for hashing into memory. The previous code used 'int', which doesn't
11752 retain enough info to hash well into very large tables.
11753 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11754
11755 * dbusbind.c: Don't possibly lose pointer info when converting.
11756 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11757 Use XPNTR rather than XHASH, so that the high-order bits of
11758 the pointer aren't lost when converting through void *.
11759
11760 * eval.c (Fautoload): Don't double-shift a pointer.
11761
11762 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11763
117642011-05-06 Juanma Barranquero <lekktu@gmail.com>
11765
11766 * gnutls.c (DEF_GNUTLS_FN):
11767 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11768
117692011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11770
11771 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11772 marker. (Bug#8610)
11773
117742011-05-05 Eli Zaretskii <eliz@gnu.org>
11775
11776 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11777 New version that can reserve upto 2GB of heap space.
11778
117792011-05-05 Chong Yidong <cyd@stupidchicken.com>
11780
11781 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11782
117832011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11784
11785 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11786 `gnutls_certificate_set_x509_key_file'.
11787
117882011-05-05 Juanma Barranquero <lekktu@gmail.com>
11789
11790 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11791 Update dependencies.
11792
117932011-05-04 Juanma Barranquero <lekktu@gmail.com>
11794
11795 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11796 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11797 Remove unused parameter `fildes'.
11798 * process.c (read_process_output, send_process): Don't pass it.
11799
118002011-05-04 Juanma Barranquero <lekktu@gmail.com>
11801
11802 Fix previous change: the library cache is defined in w32.c.
11803 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11804 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11805
118062011-05-04 Juanma Barranquero <lekktu@gmail.com>
11807
11808 Implement dynamic loading of GnuTLS on Windows.
11809
11810 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11811 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11812 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11813 Declare.
11814
11815 * gnutls.c (Qgnutls_dll): Define.
11816 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11817 (gnutls_*): Declare function pointers.
11818 (init_gnutls_functions): New function to initialize function pointers.
11819 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11820 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11821 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11822 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11823 (emacs_gnutls_write, emacs_gnutls_read)
11824 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11825 (Fgnutls_available_p): New function.
11826 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11827 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11828 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11829
11830 * image.c: Include w32.h.
11831 (Vimage_type_cache): Delete.
11832 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11833 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11834 (w32_delayed_load): Move to w32.c.
11835
11836 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11837
11838 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11839 (w32_delayed_load): Move from image.c. When loading a library, record
11840 its filename in the :loaded-from property of the library id.
11841 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11842 Initialize and staticpro them.
11843 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

11899 rather than `XVECTOR (FOO)->size'.
11900
11901 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11902 inttypes.h, as a gnulib replacement is used if it not available in

11969 Improve `doprnt' and its usage. (Bug#8545)
11970 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11971 `format_end'. Remove support for %l as a conversion specifier.
11972 Don't use xrealloc. Improve diagnostics when the %l size modifier
11973 is used. Update the commentary.
11974
11975 * eval.c (verror): Simplify calculation of size_t.

11983 change.
11984
119852011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11986
11987 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11988 This makes this file independent of the recent pseudovector change.
11989
119902011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11991
11992 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11993
11994 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11995 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11996 Remove unused local.
11997 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11998
11999 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12000 GCC 4.6.0 optimizes based on type-based alias analysis.
12001 For example, if b is of type struct buffer * and v of type struct
12002 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12003 != &v->size, and therefore "v->size = 1; b->size = 2; return
12004 v->size;" must therefore return 1. This assumption is incorrect
12005 for Emacs, since it type-puns struct Lisp_Vector * with many other
12006 types. To fix this problem, this patch adds a new type struct
12007 vectorlike_header that documents the constraints on layout of vectors
12008 and pseudovectors, and helps optimizing compilers not get fooled
12009 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12010 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12011 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12012 the size member.
12013 (XSETPVECTYPE): Rewrite in terms of new macro.
12014 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12015 This is a bit clearer, and further avoids the possibility of
12016 undesirable aliasing.
12017 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12018 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12019 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12020 since Lisp_Subr is a special case (no "next" field).
12021 (ASIZE): Now uses header.size rather than size.
12022 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12023 to avoid the hassle of writing XVECTOR (foo)->header.size.
12024 (struct vectorlike_header): New type.
12025 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12026 object, to help avoid aliasing.
12027 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12028 (SUBRP): Likewise, since Lisp_Subr is a special case.
12029 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12030 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12031 (struct Lisp_Hash_Table): Combine first two members into a single
12032 struct vectorlike_header member. All uses of "size" and "next" members
12033 changed to be "header.size" and "header.next".
12034 * buffer.h (struct buffer): Likewise.
12035 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12036 * frame.h (struct frame): Likewise.
12037 * process.h (struct Lisp_Process): Likewise.
12038 * termhooks.h (struct terminal): Likewise.
12039 * window.c (struct save_window_data, struct saved_window): Likewise.
12040 * window.h (struct window): Likewise.
12041 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12042 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12043 * buffer.c (init_buffer_once): Likewise.
12044 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12045 special case.
12046 * process.c (Fformat_network_address): Use local var for size,
12047 for brevity.
12048
12049 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12050
12051 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12052 * data.c (atof): Remove decl; no longer used or needed.
12053 (digit_to_number): Move to lread.c.
12054 (Fstring_to_number): Use new string_to_number function, to be
12055 consistent with how the Lisp reader treats infinities and NaNs.
12056 Do not assume that floating-point numbers represent EMACS_INT
12057 without losing information; this is not true on most 64-bit hosts.
12058 Avoid double-rounding errors, by insisting on integers when
12059 parsing non-base-10 numbers, as the documentation specifies.
12060 * lisp.h (string_to_number): New decl, replacing ...
12061 (isfloat_string): Remove.
12062 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12063 (read1): Do not accept +. and -. as integers; this
12064 appears to have been a coding error. Similarly, do not accept
12065 strings like +-1e0 as floating point numbers. Do not report
12066 overflow for integer overflows unless the base is not 10 which
12067 means we have no simple and reliable way to continue.
12068 Break out the floating-point parsing into a new
12069 function string_to_number, so that Fstring_to_number parses
12070 floating point numbers consistently with the Lisp reader.
12071 (digit_to_number): Move here from data.c. Make it static inline.
12072 (E_CHAR, EXP_INT): Remove, replacing with ...
12073 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12074 (string_to_number): New function, replacing isfloat_string.
12075 This function checks for valid syntax and produces the resulting
12076 Lisp float number too. Rework it so that string-to-number
12077 no longer mishandles examples like "1.0e+". Use strtoumax,
12078 so that overflow for non-base-10 numbers is reported only when
12079 there's no portable and simple way to convert to floating point.
12080
12081 * textprop.c (set_text_properties_1): Rewrite for clarity,
12082 and to avoid GCC warning about integer overflow.
12083
12084 * intervals.h (struct interval): Use EMACS_INT for members
12085 where EMACS_UINT might cause problems. See
12086 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12087 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12088 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12089 All uses changed.
12090 (offset_intervals): Tell GCC not to worry about length overflow
12091 when negating a negative length.
12092
12093 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12094 (overrun_check_free): Likewise.
12095
12096 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12097 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12098 word size.
12099
12100 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12101 (gnutls_make_error): Rename local to avoid shadowing.
12102 (gnutls_emacs_global_deinit): ifdef out; not used.
12103 (Fgnutls_boot): Use const for pointer to readonly storage.
12104 Comment out unused local. Fix pointer signedness problems.
12105
12106 * lread.c (openp): Don't stuff size_t into an 'int'.
12107 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12108 about possible signed overflow.
12109
12110 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12111 (GDK_KEY_g): Don't define if already defined.
12112 (xg_prepare_tooltip): Avoid pointer signedness problem.
12113 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12114
12115 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12116 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12117
12118 * xfns.c (Fx_window_property): Simplify a bit,
12119 to make a bit faster and to avoid GCC 4.6.0 warning.
12120 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12121
12122 * fns.c (internal_equal): Don't assume size_t fits in int.
12123
12124 * alloc.c (compact_small_strings): Tighten assertion a little.
12125
12126 Replace pEd with more-general pI, and fix some printf arg casts.
12127 * lisp.h (pI): New macro, generalizing old pEd macro to other
12128 conversion specifiers. For example, use "...%"pI"d..." rather
12129 than "...%"pEd"...".
12130 (pEd): Remove. All uses replaced with similar uses of pI.
12131 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12132 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12133 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12134 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12135 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12136 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12137 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12138 64-bit hosts.
12139 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12140 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12141 * print.c (safe_debug_print, print_object): Likewise.
12142 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12143 to int.
12144 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12145 avoiding the 0 flag, which is not portable.
12146 * process.c (Fmake_network_process): Use pI to avoid cast.
12147 * region-cache.c (pp_cache): Likewise.
12148 * xdisp.c (decode_mode_spec): Likewise.
12149 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12150 behavior on 64-bit hosts with printf arg.
12151 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12152 (x_stop_queuing_selection_requests): Likewise.
12153 (x_get_window_property): Don't truncate byte count to an 'int'
12154 when tracing.
12155
12156 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12157 here, since it parses constructs like leading '-' and spaces,
12158 which are not wanted; and it overflows with large numbers.
12159 Instead, simply match F[0-9]+, which is what is wanted anyway.
12160
12161 * alloc.c: Remove unportable assumptions about struct layout.
12162 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12163 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12164 (allocate_vectorlike, make_pure_vector): Use the new macros,
12165 plus offsetof, to remove unportable assumptions about struct layout.
12166 These assumptions hold on all porting targets that I know of, but
12167 they are not guaranteed, they're easy to remove, and removing them
12168 makes further changes easier.
12169
12170 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12171 This doesn't fix a bug but makes the code clearer.
12172 (string_overrun_cookie): Now const. Use initializers that
12173 don't formally overflow signed char, to avoid warnings.
12174 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12175 can cause Emacs to crash when string overrun checking is enabled.
12176 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12177 multiple of sizeof (EMACS_INT); it need not be, if
12178 alignof(EMACS_INT) < sizeof (EMACS_INT).
12179 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12180
121812011-04-26 Juanma Barranquero <lekktu@gmail.com>
12182
12183 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12184
121852011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12186
12187 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12188 supposed to be handshaking. (Bug#8556)
12189 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12190
121912011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12192
12193 * lisp.h (Qdebug): List symbol.
12194 * eval.c (Qdebug): Restore global linkage.
12195 * keyboard.c (debug-on-event): New variable.
12196 (handle_user_signal): Break into debugger when debug-on-event
12197 matches the current signal symbol.
12198
121992011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12200
12201 * alloc.c (check_sblock, check_string_bytes)
12202 (check_string_free_list): Convert to standard C.
12203
122042011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12205
12206 * w32.c (emacs_gnutls_push): Fix typo.
12207
122082011-04-25 Eli Zaretskii <eliz@gnu.org>
12209
12210 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12211 "cast to pointer from integer of different size".
12212
12213 Improve doprnt and its use in verror. (Bug#8545)
12214 * doprnt.c (doprnt): Document the set of format control sequences
12215 supported by the function. Use SAFE_ALLOCA instead of always
12216 using `alloca'.
12217
12218 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12219 is one byte too soon. Don't use xrealloc; instead xfree and
12220 xmalloc anew.
12221
122222011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12223
12224 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12225 callbacks stage.
12226
12227 * gnutls.c: Renamed global_initialized to
12228 gnutls_global_initialized. Added internals for the

13014 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13015 when at ZV. (Bug#8487)
13016
130172011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13018
13019 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13020 (Bug#8437)
13021 * keyboard.c (parse_tool_bar_item): Likewise.
13022 * sound.c (sound_cleanup, alsa_close): Likewise.
13023 * termcap.c (tgetent): Likewise.
13024 * xfns.c (x_default_font_parameter): Likewise.
13025 * xsettings.c (read_and_apply_settings): Likewise.
13026
13027 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13028 (overrun_check_free): Protoize.
13029
130302011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13031
13032 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13033 since callers should never pass a negative size.
13034 Change the signature to match that of plain 'read' and 'write'; see
13035 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13036 * lisp.h: Update prototypes of emacs_write and emacs_read.
13037
130382011-04-11 Eli Zaretskii <eliz@gnu.org>
13039
13040 * xdisp.c (redisplay_window): Don't try to determine the character
13041 position of the scroll margin if the window start point w->startp
13042 is outside the buffer's accessible region. (Bug#8468)
13043
130442011-04-10 Eli Zaretskii <eliz@gnu.org>
13045
13046 Fix write-region and its subroutines for buffers > 2GB.
13047 * fileio.c (a_write, e_write): Modify declaration of arguments and
13048 local variables to support buffers larger than 2GB.
13049 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13050
13051 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13052 argument, local variables, and return value.
13053
13054 * lisp.h: Update prototypes of emacs_write and emacs_read.
13055
13056 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13057
130582011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13059
13060 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13061
13062 Fix more problems found by GCC 4.6.0's static checks.
13063
13064 * xdisp.c (vmessage): Use a better test for character truncation.
13065
13066 * charset.c (load_charset_map): <, not <=, for optimization,
13067 and to avoid potential problems with integer overflow.
13068 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13069 * casetab.c (set_identity, shuffle): Likewise.
13070 * editfns.c (Fformat): Likewise.
13071 * syntax.c (skip_chars): Likewise.
13072
13073 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13074 This also lets GCC 4.6.0 generate slightly better loop code.
13075
13076 * callint.c (Fcall_interactively): <, not <=, for optimization.
13077 (Fcall_interactively): Count the number of arguments produced,
13078 not the number of arguments given. This is simpler and lets GCC
13079 4.6.0 generate slightly better code.
13080
13081 * ftfont.c: Distingish more carefully between FcChar8 and char.
13082 The previous code passed unsigned char * to a functions like
13083 strlen and xstrcasecmp that expect char *, which does not
13084 conform to the C standard.
13085 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13086 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13087 char * when the C standard requires it.
13088
13089 * keyboard.c (read_char): Remove unused var.
13090
13091 * eval.c: Port to Windows vsnprintf (Bug#8435).
13092 Include <limits.h>.
13093 (SIZE_MAX): Define if the headers do not.
13094 (verror): Do not give up if vsnprintf returns a negative count.
13095 Instead, grow the buffer. This ports to Windows vsnprintf, which
13096 does not conform to C99. Problem reported by Eli Zaretskii.
13097 Also, simplify the allocation scheme, by avoiding the need for
13098 calling realloc, and removing the ALLOCATED variable.
13099
13100 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13101
13102 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13103 But keep the doprint source code for now, as we might revamp it
13104 and use it again (Bug#8435).
13105 * lisp.h (doprnt): Remove.
13106 * Makefile.in (base_obj): Remove doprnt.o.
13107 * deps.mk (doprnt.o): Remove.
13108
13109 error: Print 32- and 64-bit integers portably (Bug#8435).
13110 Without this change, on typical 64-bit hosts error ("...%d...", N)
13111 was used to print both 32- and 64-bit integers N, which relied on
13112 undefined behavior.
13113 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13114 * lisp.h (error, verror): Mark as printf-like functions.
13115 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13116 Report overflow in size calculations when allocating printf buffer.
13117 Do not truncate output string at its first null byte.
13118 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13119 Truncate the output at a character boundary, since vsnprintf does not
13120 do that.
13121 * charset.c (check_iso_charset_parameter): Convert internal
13122 character to string before calling 'error', since %c now has the
13123 printf meaning.
13124 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13125 overflow when computing char to be passed to 'error'. Do not
13126 pass Lisp_Object to 'error'; pass the integer instead.
13127 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13128 formatted with plain %d.
13129
13130 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13131
13132 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13133
13134 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13135
13136 * xterm.c (x_catch_errors): Remove duplicate declaration.
13137
13138 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13139
13140 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13141
131422011-04-10 Jim Meyering <meyering@redhat.com>
13143
13144 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13145 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13146 return ssize_t not "int", and use size_t as the buffer length.
13147 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13148 * gnutls.h: Update declarations.
13149 * process.c (read_process_output): Use ssize_t, to match.
13150 (send_process): Likewise.
13151
131522011-04-09 Chong Yidong <cyd@stupidchicken.com>
13153
13154 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13155
131562011-04-09 Chong Yidong <cyd@stupidchicken.com>
13157
13158 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13159 Use unsigned char, to match FcChar8 type definition.
13160
13161 * xterm.c (handle_one_xevent):
13162 * xmenu.c (create_and_show_popup_menu):
13163 * xselect.c (x_decline_selection_request)
13164 (x_reply_selection_request): Avoid type-punned deref of X events.
13165
131662011-04-09 Eli Zaretskii <eliz@gnu.org>
13167
13168 Fix some uses of `int' instead of EMACS_INT.
13169 * search.c (string_match_1, fast_string_match)
13170 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13171 (scan_buffer, find_next_newline_no_quit)
13172 (find_before_next_newline, search_command, Freplace_match)
13173 (Fmatch_data): Make some `int' variables be EMACS_INT.
13174
13175 * xdisp.c (display_count_lines): 3rd argument and return value now
13176 EMACS_INT. All callers changed.
13177 (pint2hrstr): Last argument is now EMACS_INT.
13178
13179 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13180 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13181 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13182 (decode_coding_utf_16, decode_coding_emacs_mule)
13183 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13184 (decode_coding_ccl, decode_coding_charset)
13185 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13186 (decode_coding_iso_2022, decode_coding_emacs_mule)
13187 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13188 <char_offset, last_offset>: Declare EMACS_INT.
13189 (encode_coding_utf_8, encode_coding_utf_16)
13190 (encode_coding_emacs_mule, encode_invocation_designation)
13191 (encode_designation_at_bol, encode_coding_iso_2022)
13192 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13193 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13194 Declare EMACS_INT.
13195 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13196 (encode_invocation_designation): Last argument P_NCHARS is now
13197 EMACS_INT.
13198 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13199 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13200
13201 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13202 All users changed.
13203
13204 * ccl.c (Fccl_execute_on_string): Declare some variables
13205 EMACS_INT.
13206
132072011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13208
13209 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13210
132112011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13212
13213 * process.c (Fformat_network_address): Doc fix.
13214
132152011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13216
13217 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13218
132192011-04-08 Chong Yidong <cyd@stupidchicken.com>
13220
13221 * keyboard.c (read_char): Call Lisp function help-form-show,
13222 instead of using internal_with_output_to_temp_buffer.
13223 (Qhelp_form_show): New var.
13224 (syms_of_keyboard): Use DEFSYM macro.
13225
13226 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13227
13228 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13229
132302011-04-06 Chong Yidong <cyd@stupidchicken.com>
13231
13232 * process.c (Flist_processes): Remove to Lisp.
13233 (list_processes_1): Delete.
13234
132352011-04-06 Eli Zaretskii <eliz@gnu.org>
13236
13237 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13238
13239 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13240
132412011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13242
13243 Fix more problems found by GCC 4.6.0's static checks.
13244
13245 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13246
13247 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13248
13249 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13250
13251 * xdisp.c (vmessage): Mark as a printf-like function.
13252
13253 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13254
13255 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13256
13257 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13258 printf-like functions.
13259 (tiff_load): Add casts to remove these marks before passing them
13260 to system-supplied API.
13261
13262 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13263
13264 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13265 This avoids several warnings with gcc -Wstrict-overflow.
13266 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13267 directly, rather than having caller test rule sign. This avoids
13268 some unnecessary tests.
13269 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13270 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13271 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13272
13273 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13274 (xfont_open): Avoid unnecessary tests.
13275
13276 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13277
13278 * composite.h, composite.c (composition_gstring_put_cache):
13279 Use EMACS_INT, not int, for length.
13280
13281 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13282 breaking out part of COMPOSITION_DECODE_RULE.
13283 (COMPOSITION_DECODE_RULE): Use it.
13284 * composite.c (get_composition_id): Remove unused local vars,
13285 by using the new macro.
13286
13287 * textprop.c (set_text_properties_1): Change while to do-while,
13288 since the condition is always true at first.
13289
13290 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13291 (interval_deletion_adjustment): Return unsigned value.
13292 All uses changed.
13293
13294 * process.c (list_processes_1, create_pty, read_process_output):
13295 (exec_sentinel): Remove vars that were set but not used.
13296 (create_pty): Remove unnecessary "volatile"s.
13297 (Fnetwork_interface_info): Avoid possibility of int overflow.
13298 (read_process_output): Do adaptive read buffering even if carryover.
13299 (read_process_output): Simplify nbytes computation if buffered.
13300
13301 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
13302
13303 * syntax.c (scan_words): Remove var that was set but not used.
13304 (update_syntax_table): Use unsigned instead of int.
13305
13306 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13307 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13308 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13309
13310 * print.c (print_error_message): Avoid int overflow.
13311
13312 * font.c (font_list_entities): Redo for clarity,
13313 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13314
13315 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13316 (font_score): Avoid potential overflow in diff calculation.
13317
13318 * fns.c (substring_both): Remove var that is set but not used.
13319 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13320
13321 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13322
13323 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13324 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13325 can always succeed if overflow has undefined behavior.
13326
13327 * search.c (boyer_moore, wordify): Remove vars set but not used.
13328 (wordify): Omit three unnecessary tests.
13329
13330 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13331 All callers changed. This avoids the need for an unused var.
13332
13333 * casefiddle.c (casify_region): Remove var that is set but not used.
13334
13335 * dired.c (file_name_completion): Remove var that is set but not used.
13336
13337 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13338
13339 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13340 (Finsert_file_contents): Remove unnecessary code checking fd.
13341
13342 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13343 Check for integer overflow on size calculations.
13344
13345 * buffer.c (Fprevious_overlay_change): Remove var that is set
13346 but not used.
13347
13348 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13349 Remove vars that are set but not used.
13350 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13351 (timer_check_2): Mark vars as initialized.
13352
13353 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13354
13355 * image.c (lookup_image): Remove var that is set but not used.
13356 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13357
13358 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13359 that are set but not used.
13360
13361 * xfns.c (make_invisible_cursor): Don't return garbage
13362 if XCreateBitmapFromData fails (Bug#8410).
13363
13364 * xselect.c (x_get_local_selection, x_handle_property_notify):
13365 Remove vars that are set but not used.
13366
13367 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13368 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13369
13370 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13371 Remove var that is set but not used.
13372 (scroll_bar_windows_size): Now size_t, not int.
13373 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13374 Check for overflow.
13375
13376 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13377 (map_tty_color) [!defined MSDOS]: Likewise.
13378
13379 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13380
13381 * coding.c: Remove vars that are set but not used.
13382 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13383 All callers changed.
13384 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13385 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):

13387
13388 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13389 that is set but not used.
13390
13391 * print.c (print_object): Remove var that is set but not used.
13392
13393 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13394 The gnulib version avoids calling malloc in the usual case,
13395 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13396 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13397 * filelock.c (current_lock_owner): Likewise.
13398 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13399 * sysdep.c: Include allocator.h, careadlinkat.h.
13400 (emacs_no_realloc_allocator): New static constant.
13401 (emacs_readlink): New function.
13402 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13403 ../lib/careadlinkat.h.
13404
134052011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13406
13407 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13408 first non-nil return value).
13409
134102011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13411
13412 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13413 if not defined (Bug#8403).
13414
134152011-04-02 Juanma Barranquero <lekktu@gmail.com>
13416
13417 * xdisp.c (display_count_lines): Remove parameter `start',
13418 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13419 (get_char_face_and_encoding): Remove parameter `multibyte_p',

13440 later (Bug#8403).
13441
134422011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13443

13458
13459 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13460
13461 * keyboard.c (eval_dyn): New fun.
13462 (menu_item_eval_property): Use it.
13463
13464 * image.c (parse_image_spec): Use Ffunctionp.
13465
13466 * fns.c (concat, mapcar1): Accept byte-code-functions.
13467
13468 * eval.c (Fsetq): Handle lexical vars.
13469 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13470 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13471 (FletX, Flet): Obey lexical binding.
13472 (Fcommandp): Handle closures.
13473 (Feval): New `lexical' arg.
13474 (eval_sub): New function extracted from Feval. Use it almost
13475 everywhere where Feval was used. Look up vars in lexical env.
13476 Handle closures.
13477 (Ffunctionp): Move from subr.el.
13478 (Ffuncall): Handle closures.
13479 (apply_lambda): Remove `eval_flags'.
13480 (funcall_lambda): Handle closures and new byte-code-functions.
13481 (Fspecial_variable_p): New function.
13482 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13483 but without exporting it to Lisp.
13484
13485 * doc.c (Fdocumentation, store_function_docstring):
13486 * data.c (Finteractive_form): Handle closures.
13487
13488 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13489 interactive spec.

13492 New byte-codes.
13493 (exec_byte_code): New function extracted from Fbyte_code to handle new
13494 calling convention for byte-code-functions. Add new byte-codes.
13495
13496 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13497
13498 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13499
135002011-03-31 Juanma Barranquero <lekktu@gmail.com>
13501
13502 * xdisp.c (redisplay_internal): Fix prototype.
13503
135042011-03-31 Eli Zaretskii <eliz@gnu.org>
13505
13506 * xdisp.c (SCROLL_LIMIT): New macro.
13507 (try_scrolling): Use it when setting scroll_limit.
13508 Limit scrolling to 100 screen lines.
13509 (redisplay_window): Even when falling back on "recentering",
13510 position point in the window according to scroll-conservatively,
13511 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13512
13513 (try_scrolling): When point is above the window, allow searching
13514 as far as scroll_max, or one screenful, to compute vertical
13515 distance from PT to the scroll margin position. This prevents
13516 try_scrolling from unnecessarily failing when
13517 scroll-conservatively is set to a value slightly larger than the
13518 window height. Clean up the case of PT below the margin at bottom
13519 of window: scroll_max can no longer be INT_MAX. When aggressive
13520 scrolling is in use, don't let point enter the opposite scroll
13521 margin as result of the scroll.
13522 (syms_of_xdisp) <scroll-conservatively>: Document the
13523 threshold of 100 lines for never-recentering scrolling.

13532 (redisplay_internal): Remove parameter `preserve_echo_area',
13533 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13534
13535 * indent.c (Fvertical_motion):
13536 * window.c (window_scroll_pixel_based, Frecenter):
13537 Don't pass `need_y_p' to `move_it_by_lines'.
13538
135392011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13540
13541 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13542 steal a few bits to be more compact.
13543 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13544 Remove unneeded casts.
13545
13546 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13547
135482011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13549

13551 binding" message (bug#7967).
13552
135532011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13554
13555 Fix more problems found by GCC 4.6.0's static checks.
13556
13557 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13558 Remove unused local var.
13559
13560 * editfns.c (Fmessage_box): Remove unused local var.
13561
13562 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13563 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13564 Omit unused local vars.
13565 * window.c (shrink_windows): Omit unused local var.
13566 * menu.c (digest_single_submenu): Omit unused local var.
13567 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13568 Omit unused local var.
13569
13570 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13571 Don't assume string length fits in int.
13572 (keyremap_step, read_key_sequence): Use size_t for sizes.
13573 (read_key_sequence): Don't check last_real_key_start redundantly.
13574
13575 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13576 instead of alloca (Bug#8344).
13577
13578 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13579 (Fbacktrace_frame): Don't assume nframes fits in int.
13580
13581 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13582
13583 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13584 concerns.
13585
13586 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13587
13588 * cm.c (calccost): Turn while-do into do-while, for clarity.
13589
13590 * keyboard.c (syms_of_keyboard): Use the same style as later
13591 in this function when indexing through an array. This also
13592 works around GCC bug 48267.
13593
13594 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13595
13596 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

13599 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13600
13601 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13602 This avoids undefined behavior on integer overflow, and is a bit
13603 more convenient anyway since it is compared to a size_t variable.
13604
13605 Variadic C functions now count arguments with size_t, not int.
13606 This avoids an unnecessary limitation on 64-bit machines, which
13607 caused (substring ...) to crash on large vectors (Bug#8344).
13608 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13609 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13613 * editfns.c (general_insert_function): Likewise.
13614 * eval.c (struct backtrace.nargs, interactive_p)

13616 (funcall_lambda, mark_backtrace): Likewise.
13617 * fns.c (concat): Likewise.
13618 * frame.c (x_set_frame_parameters): Likewise.
13619 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13620 0 if not found, not -1. All callers changed.
13621
13622 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13623 (stack_copy_size): Now size_t, not int.
13624 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

13647 (Qcommand_hook_internal): Remove, unused.
13648 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13649 Vcommand_hook_internal.

13714 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13715
137162011-03-26 Juanma Barranquero <lekktu@gmail.com>
13717
13718 * w32.c (read_unc_volume): Use parameter `henum', instead of

13806 (fill_in_menu): Remove unused variable `items_added'.
13807
13808 * w32term.c (last_mouse_press_frame): Remove static global variable.
13809 (w32_clip_to_row): Remove unused variable `f'.
13810 (x_delete_terminal): Remove unused variable `i'.

13818
13819 * term.c (Fsuspend_tty, Fresume_tty):
13820 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13821 * window.c (temp_output_buffer_show):
13822 * insdel.c (signal_before_change):
13823 * frame.c (Fhandle_switch_frame):
13824 * fileio.c (Fdo_auto_save):
13825 * emacs.c (Fkill_emacs):
13826 * editfns.c (save_excursion_restore):
13827 * cmds.c (internal_self_insert):
13828 * callint.c (Fcall_interactively):
13829 * buffer.c (Fkill_all_local_variables):
13830 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13831 Use Frun_hooks.
13832 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13833 unconditionally since it does the check itself.
13834
138352011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13836
13837 Fix more problems found by GCC 4.5.2's static checks.
13838
13839 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13840 the first time through the loop, since we know p0 < p1 then.
13841 This also avoids a gcc -Wstrict-overflow warning.
13842
13843 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13844 leading to a memory leak, possible in functions like
13845 load_charset_map_from_file that can allocate an unbounded number
13846 of objects (Bug#8318).
13847
13848 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13849 that could (at least in theory) be that large.
13850
13851 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13852 This is less likely to overflow, and avoids undefined behavior if
13853 overflow does occur. All callers changed. Use strtoul to scan
13854 for the unsigned long integer.
13855 (pint2hrstr): Simplify and tune code slightly.
13856 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13857
13858 * scroll.c (do_scrolling): Work around GCC bug 48228.
13859 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13860
13861 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13862 This also avoids a warning with gcc -Wstrict-overflow.
13863 (validate_x_resource_name): Simplify count usage.
13864 This also avoids a warning with gcc -Wstrict-overflow.
13865
13866 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13867 fail (Bug#8306).
13868
13869 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13870
13871 * process.c (Fmake_network_process): Use socklen_t, not int,
13872 where POSIX says socklen_t is required in portable programs.
13873 This fixes a porting bug on hosts like 64-bit HP-UX, where
13874 socklen_t is wider than int (Bug#8277).
13875 (Fmake_network_process, server_accept_connection):
13876 (wait_reading_process_output, read_process_output):
13877 Likewise.
13878
13879 * process.c: Rename or move locals to avoid shadowing.
13880 (list_processes_1, Fmake_network_process):
13881 (read_process_output_error_handler, exec_sentinel_error_handler):
13882 Rename or move locals.
13883 (Fmake_network_process): Define label "retry_connect" only if needed.
13884 (Fnetwork_interface_info): Fix pointer signedness.
13885 (process_send_signal): Add cast to avoid pointer signedness problem.
13886 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13887 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13888
13889 Make tparam.h and terminfo.c consistent.
13890 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13891 Include tparam.h instead, since it declares them.
13892 * cm.h (PC): Remove extern decl; tparam.h now does this.
13893 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13894 * terminfo.c: Include tparam.h, to check interfaces.
13895 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13896 (tparam): Adjust signature to match interface in tparam.h;
13897 this removes some undefined behavior. Check that outstring and len
13898 are zero, which they always are with Emacs.
13899 * tparam.h (PC, BC, UP): New extern decls.
13900
13901 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13902 (xftfont_open): Rename locals to avoid shadowing.
13903
13904 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13905 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13906 (OTF_TAG_SYM): Omit macro if not needed.
13907 (ftfont_list): Remove unused local.
13908 (get_adstyle_property, ftfont_pattern_entity):
13909 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13910 Rename locals to avoid shadowing.
13911
13912 * xfont.c (xfont_list_family): Mark var as initialized.
13913
13914 * xml.c (make_dom): Now static.
13915
13916 * composite.c (composition_compute_stop_pos): Rename local to
13917 avoid shadowing.
13918 (composition_reseat_it): Remove unused locals.
13919 (find_automatic_composition, composition_adjust_point): Likewise.
13920 (composition_update_it): Mark var as initialized.
13921 (find_automatic_composition): Mark vars as initialized,
13922 with a FIXME (Bug#8290).
13923
13924 character.h: Rename locals to avoid shadowing.
13925 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13926 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13927 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13928 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13929 to avoid shadowing.
13930
13931 * textprop.c (property_change_between_p): Remove; unused.
13932
13933 * intervals.c (interval_start_pos): Now static.
13934
13935 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13936
13937 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13938 Rename locals to avoid shadowing.
13939
13940 * sound.c (wav_play, au_play, Fplay_sound_internal):
13941 Fix pointer signedness.
13942 (alsa_choose_format): Remove unused local var.
13943 (wav_play): Initialize a variable to 0, to prevent undefined
13944 behavior (Bug#8278).
13945
13946 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13947
13948 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13949
13950 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13951 clobbering (Bug#8298).
13952 * sysdep.c (sys_subshell): Likewise.
13953 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13954
13955 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13956 This should get cleaned up, so that child_setup has the
13957 same signature on all platforms.
13958
13959 * callproc.c (call_process_cleanup): Now static.
13960 (relocate_fd): Rename locals to avoid shadowing.
13961
139622011-03-22 Chong Yidong <cyd@stupidchicken.com>
13963
13964 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13965 not to be necessary, and produces flickering.
13966
139672011-03-20 Glenn Morris <rgm@gnu.org>
13968
13969 * config.in: Remove file.
13970
139712011-03-20 Juanma Barranquero <lekktu@gmail.com>
13972
13973 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13974 are now in src/globals.h.
13975 (syms_of_minibuf): Remove spurious & from previous change.
13976
139772011-03-20 Leo Liu <sdl.web@gmail.com>
13978
13979 * minibuf.c (completing-read-function): New variable.
13980 (completing-read-default): Rename from completing-read.
13981 (completing-read): Call completing-read-function.
13982
139832011-03-19 Juanma Barranquero <lekktu@gmail.com>
13984
13985 * xfaces.c (Fx_load_color_file):
13986 Read color file from absolute filename (bug#8250).
13987
139882011-03-19 Juanma Barranquero <lekktu@gmail.com>
13989
13990 * makefile.w32-in: Update dependencies.
13991
139922011-03-17 Eli Zaretskii <eliz@gnu.org>
13993
13994 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
13995
139962011-03-17 Paul Eggert <eggert@cs.ucla.edu>
13997
13998 Fix more problems found by GCC 4.5.2's static checks.
13999
14000 * process.c (make_serial_process_unwind, send_process_trap):
14001 (sigchld_handler): Now static.
14002
14003 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14004 That way, the code declares only the vars that it needs.
14005 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14006 * s/cygwin.h (PTY_ITERATION): Likewise.
14007 * s/darwin.h (PTY_ITERATION): Likewise.
14008 * s/gnu-linux.h (PTY_ITERATION): Likewise.
14009
14010 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.

14019 to avoid gcc -Wbad-function-cast warning.
14020 Use a different way to cause a compilation error if anyone uses
14021 n rather than nn, a way that does not involve shadowing.
14022 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14023
14024 * deps.mk (unexalpha.o): Remove; unused.
14025

14029 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14030 Depend on unexec.h.
14031 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14032 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
14033 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
14034 Change as necessary to match prototype in unexec.h.
14035
14036 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
14037 shadowing.
14038 (back_comment, skip_chars): Mark vars as initialized.
14039
14040 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

14045
14046 * print.c (Fredirect_debugging_output): Fix pointer signedess.
14047
14048 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
14049 warning when compiling print.c.
14050
14051 * font.c (font_unparse_fcname): Abort in an "impossible" situation
14052 instead of using an uninitialized var.
14053 (font_sort_entities): Mark var as initialized.
14054
14055 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
14056

14058 pointers to constants.
14059 (font_parse_fcname): Remove unused vars.
14060 (font_delete_unmatched): Now static.
14061 (font_get_spec): Remove; unused.
14062 (font_style_to_value, font_prop_validate_style, font_unparse_fcname):
14063 (font_update_drivers, Ffont_get_glyphs, font_add_log):
14064 Rename or move locals to avoid shadowing.
14065
14066 * fns.c (require_nesting_list, require_unwind): Now static.
14067 (Ffillarray): Rename locals to avoid shadowing.
14068
14069 * floatfns.c (domain_error2): Define only if needed.
14070 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
14071
14072 * alloc.c (mark_backtrace): Move decl from here ...
14073 * lisp.h: ... to here, so that it can be checked.
14074
14075 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
14076 (Fdefvar): Rewrite so as not to use empty "else".
14077 (lisp_indirect_variable): Name an expression,
14078 to avoid gcc -Wbad-function-cast warning.
14079 (Fdefvar): Rename locals to avoid shadowing.
14080
14081 * callint.c (quotify_arg, quotify_args): Now static.
14082 (Fcall_interactively): Rename locals to avoid shadowing.
14083 Use const pointer when appropriate.
14084
14085 * lisp.h (get_system_name, get_operating_system_release):
14086 Move decls here, to check interfaces.
14087 * process.c (get_operating_system_release): Move decl to lisp.h.
14088 * xrdb.c (get_system_name): Likewise.
14089 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14090 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14091 some of which prompt warnings from gcc -Wbad-function-cast.
14092 (Fformat_time_string, Fencode_time, Finsert_char):
14093 (Ftranslate_region_internal, Fformat):
14094 Rename or remove local vars to avoid shadowing.
14095 (Ftranslate_region_internal): Mark var as initialized.
14096
14097 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14098 avoid shadowing.
14099
14100 * lisp.h (eassert): Check that the argument compiles, even if
14101 ENABLE_CHECKING is not defined.
14102
14103 * data.c (Findirect_variable): Name an expression, to avoid
14104 gcc -Wbad-function-cast warning.
14105 (default_value, arithcompare, arith_driver, arith_error): Now static.
14106 (store_symval_forwarding): Rename local to avoid shadowing.

14114 (mark_stack): Move local variables into the #ifdef region where
14115 they're used.
14116 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14117 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14118 needed otherwise.
14119 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14120 (GC_STRING_CHARS): Remove; not used.
14121 (Fmemory_limit): Cast sbrk's returned value to char *.
14122
14123 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14124 avoids undefined behavior in theory.
14125
14126 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14127
14128 Use functions, not macros, for up- and down-casing (Bug#8254).
14129 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14130 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14131 to use the following functions instead of these macros.
14132 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14133 EMACS_INT, since callers assume the returned value fits in int.
14134 (upcase1): Likewise, for UPCASE_TABLE.
14135 (uppercasep, lowercasep, upcase): New static inline functions.
14136 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14137 the race-condition problem in the old DOWNCASE.
14138
14139 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14140 Rename locals to avoid shadowing.
14141 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14142 (regex_compile, re_search_2, re_match_2_internal):
14143 Remove unused local vars.
14144 (FREE_VAR): Rewrite so as not to use empty "else",
14145 which gcc can warn about.
14146 (regex_compile, re_match_2_internal): Mark locals as initialized.
14147 (RETALLOC_IF): Define only if needed.
14148 (WORDCHAR_P): Likewise. This one is never needed, but is used
14149 only in a comment talking about a compiler bug, so put inside
14150 the #if 0 of that comment.
14151 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14152 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14153 Remove; unused.
14154
14155 * search.c (boyer_moore): Rename locals to avoid shadowing.
14156 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14157 (PREV_CHAR_BOUNDARY): Likewise.
14158
14159 * search.c (simple_search): Remove unused var.
14160
14161 * dired.c (compile_pattern): Move decl from here ...
14162 * lisp.h: ... to here, so that it can be checked.
14163 (struct re_registers): New forward decl.
14164
14165 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
14166
14167 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14168 All uses changed.
14169 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14170 Rename locals to avoid shadowing.
14171 (Fvertical_motion): Mark locals as initialized.
14172
14173 * casefiddle.c (casify_object, casify_region): Now static.
14174 (casify_region): Mark local as initialized.
14175
14176 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14177
14178 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14179 New macros, so that the caller can use some names other than
14180 gcpro1, gcpro2, etc.
14181 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14182 of the new macros.
14183 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14184 argument, for consistency with GCPRO2_VAR, etc: it is now the
14185 prefix of the variable, not the variable itself. All uses
14186 changed.
14187 * dired.c (directory_files_internal, file_name_completion):
14188 Rename locals to avoid shadowing.
14189
14190 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14191 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14192 dired.c's scmp function, had undefined behavior.
14193 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14194 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14195 * buffer.h: ... to here, because these macros use current_buffer,
14196 and the new implementation with inline functions needs to have
14197 current_buffer in scope now, rather than later when the macros
14198 are used.
14199 (downcase, upcase1): New static inline functions.
14200 (DOWNCASE, UPCASE1): Reimplement using these functions.
14201 This avoids undefined behavior in expressions like
14202 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14203 from race conditions in accessing the global variables
14204 case_temp1 and case_temp2.
14205 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14206 * lisp.h (case_temp1, case_temp2): Remove their decls.
14207 * character.h (ASCII_CHAR_P): Move from here ...
14208 * lisp.h: ... to here, so that the inline functions mentioned
14209 above can use them.
14210

14600 Use "else { /* comment */ }" rather than "else /* comment */;"
14601 for clarity, and to avoid gcc -Wempty-body warning.
14602 (Fdefine_coding_system_internal): Don't redeclare 'i' inside
14603 a block, when the outer 'i' will do.

14609 Rename locals to avoid shadowing.
14610 * character.h (FETCH_STRING_CHAR_ADVANCE): Likewise.
14611 * coding.c (emacs_mule_char, encode_invocation_designation):
14612 Now static, since they're not used elsewhere.
14613 (decode_coding_iso_2022): Add "default: abort ();" as a safety check.
14614 (decode_coding_object, encode_coding_object, detect_coding_system):
14615 (decode_coding_emacs_mule): Mark variables that gcc
14616 -Wuninitialized does not deduce are never used uninitialized.
14617 (detect_coding_iso_2022): Initialize a local variable that might
14618 be used uninitialized. Leave a FIXME because it's not clear that
14619 this initialization is needed. (Bug#8211)
14620 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
14621 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

14652 Move these decls to tparam.h, and make them agree with what
14653 is actually in tparam.c. The previous trick of using incompatible
14654 decls in different modules does not conform to the C standard.
