181 * alloc.c (listn): Fix the order the arguments are consed onto the
184 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
185 enumeration constants, as PURE and HEAP are too general, and clash
186 with other headers and sources, such as gmalloc.c and the
187 MS-Windows system headers. All users changed.
189 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

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

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

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

273 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
274 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
275 not be usable in #if. This simplifies things.
277 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
279 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
281 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

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

314 more convenient now. All uses changed.
315 (VALMASK) [USE_LSB_TAG]: Also define in this case.

326 add argument, tune behavior, and adjust all callers.
328 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
330 Use typedef for EMACS_INT, EMACS_UINT.
331 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
332 than macros. This simplifies debugging in the usual case, since
333 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
334 and it allows expressions involving EMACS_INT casts.
335 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
337 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

350 * buffer.c (Fkill_buffer): Adjust indirection counters when the
351 buffer is definitely dead. This should really fix an issue reported
352 by Christoph Scholtes again. (Bug#12007).
353 (init_buffer_once): Initialize indirection counters of
354 buffer_defaults and buffer_local_symbols (for sanity and safety).
356 2012-07-24 Eli Zaretskii <eliz@gnu.org>
358 * xdisp.c (init_iterator): Don't compute dimensions of truncation
359 and continuation glyphs on tooltip frames, leave them at zero.
360 Avoids continued lines in tooltips. (Bug#11832)
362 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
364 Simplify copy_overlay.
365 * buffer.c (copy_overlay): Simplify. Use build_marker.

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

419 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
421 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
422 as it's limited by the amount of memory, not by INT_MAX.
424 2012-07-21 Eli Zaretskii <eliz@gnu.org>
426 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
427 in special-event-map. See the discussion at

1150 * s/aix4-2.h (unix): Remove; no longer needed.
1152 EMACS_TIME simplification (Bug#11875).
1153 This replaces macros (which typically do not work in GDB)

1155 The functional style also makes code easier to read and maintain.
1156 * systime.h: Include <sys/time.h> on all hosts, not just if
1157 WINDOWSNT, since 'struct timeval' is needed in general.

1173 (add_emacs_time, sub_emacs_time): New functions.
1174 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1197 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1198 Prefer snprintf to strncpy.
1199 * nsterm.m (ns_term_init):
1200 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1201 * nsterm.m (ns_term_init):
1202 Avoid the need for strncpy, by using build_string or
1203 make_unibyte_string directly. Use dtoastr, not snprintf.
1204 * process.c (Fmake_network_process): Diagnose service names that
1205 are too long, rather than silently truncating them or creating
1206 non-null-terminated names.
1207 (Fnetwork_interface_info): Likewise, for interface names.
1208 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1209 Prefer sprintf to strncat.

1223 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1224 where argument type is known to be a Lisp_Cons.

1279 O_RDONLY already includes it).
1281 Stop ns builds setting the EMACSLOADPATH environment variable.
1282 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1283 Now it does not set EMACSLOADPATH, just returns the load-path string.

1285 * lread.c [HAVE_NS]: Include nsterm.h.
1286 (init_lread) [HAVE_NS]: Use ns_load_path.

1296 (ns_init_paths): Do not set EMACSPATH.

1356 Move marker debugging code under MARKER_DEBUG.
1357 * marker.c (MARKER_DEBUG): Move marker debugging code under
1358 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1359 for bootstrap with --enable-checking (~3x slowdown reported

1372 (display_line): Add commentary about displaying truncation glyphs
1374 (produce_special_glyphs): Move here from term.c.
1376 * term.c (produce_special_glyphs): Move to xdisp.c.
1378 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1381 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1383 * xdisp.c (display_line): Avoid warning about implicit declaration
1386 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1388 * lisp.h: Remove empty conditional.
1390 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1392 * lread.c (load_path_check): Now static.
1394 Fix some minor --with-ns problems found by static checking.
1395 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1396 (x_set_font) [!HAVE_X_WINDOWS]:
1397 * image.c (xpm_load_image) [HAVE_NS]:
1398 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1399 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1400 Remove unused local.
1401 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1402 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1403 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1404 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1405 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1406 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1407 Fix pointer signedness problem.
1408 * xfaces.c (FRAME_X_FONT_TABLE):
1409 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1411 2012-07-07 Glenn Morris <rgm@gnu.org>
1413 * lread.c (load_path_check): New function, split from init_lread.
1414 (init_lread): Reorganize. Motivation:
1415 If EMACSLOADPATH is set, check/warn about that rather than the
1416 defaults, which we are not going to use. Hence we can remove
1417 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1418 Don't warn if site-lisp directories are missing.
1419 If not installed, start from a blank load-path, since
1420 PATH_LOADSEARCH refers to the eventual installation directories.
1422 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1424 Support truncation and continuation glyphs on GUI frames, when
1425 fringes are disabled. (Bug#11832)
1426 * xdisp.c (init_iterator): Get dimensions of truncation and
1427 continuation glyphs even if on GUI frames. Adjust
1428 it->last_visible_x on GUI frames when the left or right fringes,
1429 or both, are absent.
1430 (start_display, move_it_in_display_line_to): Handle the case of a
1431 GUI frame without a fringe to display continuation or truncation
1433 (insert_left_trunc_glyphs): Support GUI frames: make sure
1434 truncation glyphs overwrite enough glyphs from the current line to
1435 have sufficient space in pixels.
1436 (display_line): Support truncation and continuation glyphs on GUI
1437 frames. If some spare pixels are left on the line after inserting
1438 the truncation glyphs, fill that space with a stretch glyph of a
1439 suitably computed width.
1441 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1442 produce_glyphs, to support GUI sessions.
1444 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1446 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1448 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1450 Do not require float-time's arg to fit in time_t (Bug#11825).
1451 This works better on hosts where time_t is unsigned, and where
1452 float-time is applied to the (negative) difference between two times.
1453 * editfns.c (decode_time_components): Last arg is now double *,
1454 not int *, and means to store all the result as a double, without
1455 worrying about whether the seconds part fits in time_t.
1456 All callers changed.
1457 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1458 All callers changed.
1459 (Ffloat_time): Do not fail merely because the specified time falls
1460 outside of time_t range.
1462 2012-07-07 Glenn Morris <rgm@gnu.org>
1464 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1465 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1466 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1468 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1470 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1471 Update dependencies.
1473 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1475 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1477 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1478 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1479 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1480 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1481 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1482 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1484 * xfont.c (compare_font_names): Redo to omit the need for casts.
1486 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1488 * xfns.c (Fx_change_window_property): Doc fix.
1489 * w32fns.c (Fx_change_window_property): Doc fix.
1491 * w32fns.c (Fx_window_property): Accept the same arguments as the
1492 X Windows version. Doc fix.
1493 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1495 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1496 Eli Zaretskii <eliz@gnu.org>
1498 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1499 Windows-specific code from nt/config.nt moved here.
1500 Obsolete settings removed.
1502 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1504 * process.c: Avoid unnecessary calls to gettime.
1505 (wait_reading_process_output): Don't get the time of day
1506 when gobbling data immediately and not waiting, as there's no need
1507 for it in that case. This removes a FIXME.
1509 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1511 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1512 is defined (Bug#11768).
1514 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1516 Fix marker debugging code.
1517 * marker.c (byte_char_debug_check): Do not perform the check
1518 if buffer is not multibyte.
1519 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1520 Call byte_char_debug_check with correct arguments.
1522 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1524 Compile marker debugging code only if ENABLE_CHECKING is defined.
1525 * marker.c (byte_char_debug_check, count_markers):
1526 Use only if ENABLE_CHECKING is defined.
1527 (byte_debug_flag): Remove.
1528 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1529 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1531 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1533 Avoid code repetition in marker-related functions.
1534 * marker.c (attach_marker): New function.
1535 (Fset_marker, set_marker_restricted, set_marker_both)
1536 (set_marker_restricted_both): Use it.
1537 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1538 Consistently rename charno to charpos.
1539 (marker_position): Add eassert.
1540 (marker_byte_position): Convert to eassert.
1542 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1544 Simplify list operations in unchain_overlay and unchain_marker.
1545 * buffer.c (unchain_overlay): Simplify. Add comment.
1546 * marker.c (unchain_marker): Simplify. Fix comments.
1548 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1550 Introduce fast path for the widely used marker operation.
1551 * alloc.c (build_marker): New function.
1552 * lisp.h (build_marker): New prototype.
1553 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1554 * composite.c (autocmp_chars): Likewise.
1555 * editfns.c (buildmark): Remove.
1556 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1557 (save_restriction_save): Use build_marker.
1558 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1559 * window.c (save_window_save): Likewise.
1561 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1563 Do not use Fdelete_overlay in delete_all_overlays
1564 to avoid redundant calls to unchain_overlay.
1565 * buffer.c (drop_overlay): New function.
1566 (delete_all_overlays, Fdelete_overlay): Use it.
1567 * minibuf.c (get_minibuffer): Fix comment.
1569 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1571 Port to OpenBSD 5.1 amd64.
1572 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1573 This is needed for OpenBSD, and should be harmless on all BSD systems.
1574 Also, include <sys/sysctl.h>, as it should be available on all
1575 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1576 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1577 use p_pid member, not kp_proc.pid.
1579 2012-07-06 Glenn Morris <rgm@gnu.org>
1581 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1583 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1585 More xmalloc and related cleanup.
1586 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1587 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
1588 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

1590 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
1591 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
1592 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
1593 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1594 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1596 Omit needless casts involving void * pointers and allocation.
1597 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1598 as the former is more robust if P's type is changed.
1599 Prefer xzalloc to xmalloc + memset 0.
1600 Simplify malloc-or-realloc to realloc.
1601 Don't worry about xmalloc returning a null pointer.
1602 Prefer xstrdup to xmalloc + strcpy.
1603 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1605 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1606 alloca of a constant.
1608 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1610 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1611 hscroll is larger than the line width. Fixes long and futile
1612 looping inside extend_face_to_end_of_line (on a TTY) producing
1613 glyphs that are not needed and thrown away.
1615 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1617 * marker.c (set_marker_restricted_both): Simplify by using
1620 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1622 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1624 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1626 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
1627 not defined (Bug#11768).
1628 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1629 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1630 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1631 followed by gtk_box_set_homogeneous (Bug#11768).
1632 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1633 (update_theme_scrollbar_width, xg_create_scroll_bar):
1634 Use gtk_scrollbar_new (Bug#11768).
1635 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1636 (is_box_type): New function (Bug#11768).
1637 (xg_tool_item_stale_p): Call is_box_type.
1638 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1639 with default display (Bug#11768).
1641 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1643 * xdisp.c (window_hscroll_limited): New function.
1644 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1645 coordinates when window's hscroll is set to insanely large
1648 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1650 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1651 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1653 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1656 * lisp.h (xzalloc): New prototype. Omit needless casts.
1657 * alloc.c (xzalloc): New function. Omit needless casts.
1658 * charset.c: Omit needless casts. Convert all calls to
1659 xmalloc with following memset to xzalloc.

1709 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1711 * fileio.c (time_error_value): Check the right error number.
1712 Problem reported by Troels Nielsen in
1713 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1715 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1717 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1718 This should be fixed in a better way; see Eli Zaretskii in
1719 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1720 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1722 * fileio.c (time_error_value): Rename from special_mtime.
1723 The old name's problems were noted by Eli Zaretskii in
1724 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1726 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1727 This variable's comment says Emacs needs at least one GDB-visible
1728 symbol of type enum pvec_type, to work around GDB problems.
1729 The symbol's value doesn't matter.
1731 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1732 that causes compilation to fail on pre-C99 compilers.
1734 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1736 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1737 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1739 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1741 * buffer.c (init_buffer_once): Fix initialization of
1742 headers for buffer_defaults and buffer_local_symbols.
1743 Reported by Juanma Barranquero <lekktu@gmail.com>.
1745 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1747 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1748 * lisp.h (enum pvec_type): Use fewer bits.
1749 (PSEUDOVECTOR_SIZE_BITS): New constant.
1750 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1751 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1752 change in pvec_type.
1753 (PSEUDOVECTOR_TYPEP): New macro.
1754 (TYPED_PSEUDOVECTORP): Use it.
1755 * fns.c (internal_equal): Adapt code to extract pvectype.
1756 * emacs.c (gdb_pvec_type): Update type.
1757 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1758 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1759 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1760 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1761 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1762 abusing vector->header.next.nbytes.
1763 (live_vector_p): Use PVEC_TYPE.
1764 (mark_object): Adapt code to extract pvectype. Use switch.
1766 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1768 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1769 Tighten new eassert a bit.
1771 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1773 Fix compilation with --enable-gcc-warnings and -O1
1775 * doprnt.c (doprnt): Change type of tem to int, initialize
1776 to avoid compiler warning. Add eassert.
1777 * search.c (simple_search): Initialize match_byte to avoid
1778 compiler warning. Add eassert.
1780 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1782 Avoid weird behavior with large horizontal scrolls.
1783 Without this change, for example, large hscroll values would
1784 mess up Emacs's display on Fedora 15 x86, presumably due to
1785 overflows in int calculations in the display code.
1786 Also, if buffers had long lines, Emacs would freeze.
1787 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1788 (set_window_hscroll): New function, containing the old guts of
1789 Fset_window_hscroll. Return the clipped value.
1790 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1791 This avoids the need to check against PTRDIFF_MAX.
1793 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1795 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1797 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1799 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1801 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1802 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1803 since GCC 4.4.6 issues a bogus warning for them.
1805 Fix bugs in file timestamp newness comparisons.
1806 * fileio.c (Ffile_newer_than_file_p):
1807 * lread.c (Fload): Use full timestamp resolution of files,
1808 not just the 1-second resolution, so that files that are only
1809 slightly newer still count as newer.
1810 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1811 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1813 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1815 * fileio.c: Improve handling of file time marker. (Bug#11852)
1816 (special_mtime): New function.
1817 (Finsert_file_contents, Fverify_visited_file_modtime):
1818 Use it to set special mtime values consistently.
1820 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1822 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1823 marker for non-existing file. (Bug#11852)
1825 2012-07-03 Glenn Morris <rgm@gnu.org>
1827 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1828 and did not make it into globals.h).
1830 2012-07-03 Tom Tromey <tromey@redhat.com>
1832 * window.c (Fset_window_margins, Fset_window_fringes)

1876 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1877 values which aren't power of 2.
1878 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1879 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1882 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1884 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1886 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1888 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1890 * alloc.c (allocate_vector_block): Remove redundant
1891 calls to mallopt if DOUG_LEA_MALLOC is defined.
1892 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1893 avoid calls to mallopt if zero_vector is returned.
1895 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1897 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1898 is enabled, avoid dereferencing NULL current_sblock if
1901 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1903 Cleanup basic buffer management.
1904 * buffer.h (struct buffer): Change layout to use generic vector
1905 marking code. Fix some comments. Change type of 'clip_changed'
1906 to bitfield. Remove unused #ifndef old.
1907 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1908 (GET_OVERLAYS_AT): Fix indentation.
1909 (for_each_per_buffer_object_at): New macro.
1910 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

1913 * alloc.c (allocate_buffer): Adjust to match new layout of
1914 struct buffer. Fix comment.
1915 (mark_overlay): New function.

1917 Lisp area of struct buffer.
1918 (mark_object): Use it. Adjust marking of misc objects
1919 and related comments.
1921 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1923 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1924 wrapper that is not needed because the wrapped code is a no-op (zero
1925 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1926 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1928 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1930 * alloc.c (mark_buffer): Simplify. Remove prototype.
1931 (mark_object): Add comment. Reorganize marking of vector-like
1932 objects. Use CHECK_LIVE for all vector-like objects except buffers
1933 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1934 redundant calls to mark_vectorlike for bool vectors.
1936 2012-06-30 Glenn Morris <rgm@gnu.org>
1938 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1940 * epaths.in (PATH_SITELOADSEARCH): New.
1941 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1942 This is rather than relying on --enable-locallisppath elements
1943 having "site-lisp" in their names. (Bug#10208#25, 11658)
1945 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1947 * w32proc.c (sys_select): Accept and ignore one more argument.
1949 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1951 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1952 (pselect) [!MS_DOS]: Redirect to sys_select.
1954 * sysdep.c: Don't include dos.h and dosfns.h.
1956 * process.c (sys_select):
1957 * msdos.c (sys_select): Accept one more argument and ignore it.
1959 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1960 adapt data types and code to that.
1963 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1964 which clashes with the gnulib function of the same name.
1966 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1968 * font.c (font_style_to_value, font_style_symbolic)
1969 (font_prop_validate_style): Add type checks for values in
1972 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1974 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1977 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1979 * xdisp.c (try_window_id): Undo last change.
1981 * w32.c (getwd): Adjust commentary about startup_dir.
1982 (init_environment): Always call sys_access, even in non-MSVC
1983 builds. Don't chdir to the directory of the Emacs executable.
1984 This undoes code from 1997 which was justified by the need to
1985 "avoid conflicts when removing and renaming directories". But its
1986 downside was that every relative file name was being interpreted
1987 relative to the directory of the Emacs executable, which can never
1988 be TRT. In particular, it broke sys_access when called with
1989 relative file names.
1990 (sys_access): Map GetLastError to errno.
1992 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1994 * window.h (struct window): Change type of 'fringes_outside_margins'

1998 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2001 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

2010 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2012 * editfns.c (region_limit): Fix type mismatch.
2014 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2016 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2017 undefined. Convert from xassert to eassert.
2018 * nsmenu.m: Convert from xassert to eassert.

2027 Avoid integer overflow on scroll-left and scroll-right.
2028 * window.c (HSCROLL_MAX): New macro.
2029 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

2034 * window.h (struct window): Change type of 'hscroll',
2035 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2036 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2037 Adjust users accordingly.
2038 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2039 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2040 from EMACS_INT to ptrdiff_t.
2041 (make_window): Omit redundant initialization.

2047 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2116 * alloc.c (allocate_string): Omit intervals initialization.
2117 * alloc.c (make_uninit_multibyte_string): Initialize intervals

2176 a better opportunity to optimize away calls to strlen when the
2177 function is called with compile-time constant argument.
2178 * image.c (imagemagick_error): Convert to build_string.
2179 * w32proc.c (sys_spawnve): Likewise.

2182 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2184 Use sprintf return value instead of invoking strlen on result.
2185 In the old days this wasn't portable, since some sprintf
2186 implementations returned char *. But they died out years ago and
2187 Emacs already assumes sprintf returns int.
2188 Similarly for float_to_string.
2189 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2190 * ccl.c (ccl_driver):

2196 * xfns.c (syms_of_xfns):
2197 Use sprintf or float_to_string result to avoid need to call strlen.
2198 * data.c (Fnumber_to_string):
2199 Use make_unibyte_string, since the string must be ASCII.
2200 * lisp.h, print.c (float_to_string): Now returns int length.
2201 * term.c (produce_glyphless_glyph):
2202 Use sprintf result rather than recomputing it.
2204 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

2235 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2237 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2240 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2242 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2243 instead of truncating it to 63 (admittedly a generous limit).
2245 * process.c: Fix spelling and caps in comments.
2247 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2249 * emacs.c (setpgrp): Remove definition, unused.

2303 * keyboard.c (kbd_buffer_get_event):

2319 * makefile.w32-in: Update dependencies.

2326 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2327 Privately reported by Herbert J. Skuhra.
2328 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2330 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

2339 language ID in the event parameters.
2341 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2342 event.code, not the obscure "character set ID".
2344 2012-06-23 Chong Yidong <cyd@gnu.org>

2365 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2366 Privately reported by Herbert J. Skuhra.
2367 [__FreeBSD__]: Remove "*/" typo after "#include".
2368 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2369 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2370 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2371 Don't assume EMACS_TIME and struct timeval are the same type.
2373 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2375 Support higher-resolution time stamps (Bug#9000).
2376 The time stamps are only nanosecond-resolution at the C level,
2377 since that's the best that any real-world system supports now.
2378 But they are picosecond-resolution at the Lisp level, as that's
2379 easy, and leaves room for future OS improvements.
2381 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2384 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2385 Don't get current time unless it's needed.
2387 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2388 now provides it if it's absent.
2389 (start_atimer): Port to higher-res time stamps.
2390 Check for time stamp overflow. Don't get current time more
2391 often than is needed.
2393 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2394 Include systime.h, not time.h.
2395 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2397 * dired.c: Include stat-time.h.
2398 (Ffile-attributes): File times now have higher resolution.
2400 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2401 (struct image): Timestamp now has higher resolution.
2403 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2404 has at least microseconds now. All uses removed.
2405 (update_frame, update_single_window, update_window, update_frame_1)
2406 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2408 * editfns.c (time_overflow): Now extern.
2409 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2410 (float-time, Fformat_time_string, Fcurrent_time_string)
2411 (Fcurrent_time_zone): Accept and generate higher-resolution

2414 (decode_time_components, lisp_seconds_argument): New functions.
2415 (make_time): Now static.
2416 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2417 Report an error if the time is invalid, rather than having the caller
2420 * fileio.c: Include <stat-time.h>
2421 (Fcopy_file): Copy higher-resolution time stamps.
2422 Prefer to set the time stamp via a file descriptor if that works.
2423 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2424 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2425 (Fvisited_file_modtime, Fset_visited_file_modtime):
2426 Support higher-resolution time stamps.
2428 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2430 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2432 * image.c (prepare_image_for_display, clear_image_cache)
2433 (lookup_image): Port to higer-resolution time stamps.
2435 * keyboard.c (start_polling, bind_polling_period):
2436 Check for time stamp overflow.
2437 (read_char, kbd_buffer_get_event, timer_start_idle)
2438 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2439 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2440 Port to higher-resolution time stamps. Do not assume time_t is signed.
2441 (decode_timer): New function. Timers are now vectors of length 9,
2442 not 8, to accommodate the picosecond component.
2443 (timer_check_2): Use it.
2445 * nsterm.m (select_timeout, timeval_subtract): Remove.
2446 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2447 as they're a bit more accurate and handle overflow better.
2448 (ns_select): Change prototype to be compatible with pselect.
2449 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2450 * nsterm.h (ns_select): Adjust prototype.
2452 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2453 us-resolution time stamps.
2454 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2456 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2458 * lisp.h (time_overflow): New decl.
2459 (wait_reading_process_output): First arg is now intmax_t, not int,
2460 to accommodate larger waits.
2462 * process.h (struct Lisp_Process.read_output_delay):
2463 Now counts nanoseconds, not microseconds.
2464 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2466 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2467 (wait_reading_process_output):
2468 Port to ns-resolution time stamps.
2469 (Faccept_process_output, wait_reading_process_output):
2470 Check for time stamp overflow. Do not assume time_t is signed.
2471 (select_wrapper): Remove; we now use pselect.
2472 (Fprocess_attributes): Now generates ns-resolution time stamps.
2474 * sysdep.c: Include utimens.h. Don't include utime.h
2475 or worry about struct utimbuf; gnulib does that for us now.
2476 (gettimeofday): Remove; gnulib provides a substitute.
2477 (make_timeval): New function.
2478 (set_file_times): Now sets ns-resolution time stamps.
2479 New arg FD; all uses changed.
2480 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2481 (system_process_attributes):
2482 Now returns ns-resolution time stamp. All uses changed.
2483 Check for time stamp overflow.
2485 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2486 provides a substitute now.
2488 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2489 since it guarantees struct timespec.
2490 (EMACS_TIME): Now struct timespec, so that we can support
2491 ns-resolution time stamps.
2492 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2493 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2494 (EMACS_USECS): Remove.
2495 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2496 so multiply the arg by 1000 before storing it.
2497 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2499 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2500 Port to ns-resolution time stamps.
2501 (EMACS_TIME_NEG_P): Remove; replaced by....
2502 (EMACS_TIME_SIGN): New macro.
2503 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2504 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2505 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2506 (make_timeval, make_lisp_time, decode_time_components): New decls.
2507 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2508 that it mishandled time_t overflow. You can't compare by subtracting!
2509 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2510 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2512 * term.c: Include <sys/time.h>.
2513 (timeval_to_Time): New function, for proper overflow wraparound.
2514 (term_mouse_position, term_mouse_click): Use it.

2518 (Fprimitive_undo): Use them when restoring time stamps.
2520 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2521 (w32_get_internal_run_time):
2522 Port to higher-resolution Emacs time stamps.
2523 (ltime): Now accepts single 64-bit integer, as that's more convenient
2526 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2528 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2529 for compatibility with pselect. Support ns-resolution time stamps.
2531 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2533 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2534 Check for time stamp overflow, and support ns-resolution time stamps.
2536 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2537 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2538 (timeval_subtract): Remove; no longer needed.
2539 (XTflash, XTring_bell, x_wait_for_event):
2540 Port to ns-resolution time stamps. Don't assume time_t is signed.
2542 2012-06-22 Chong Yidong <cyd@gnu.org>

2546 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2548 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2549 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2550 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2551 staticidx goes up to 1597 out of 1600 = 0x640.)
2553 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2555 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2556 Otherwise, the umask might be mistakenly 0 while handling input signals.

2578 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2580 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

2589 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2590 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2591 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2592 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2593 (METER_1, METER_2): Simplify.
2595 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

2599 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2601 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2602 gets killed during executing of this function (Bug#11665).
2603 Try to always return Qt when the buffer has been actually killed.
2604 (Vkill_buffer_query_functions): In doc-string say that functions
2605 run by this hook should not change the current buffer.
2607 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2609 Fix recently-introduced process.c problems found by static checking.

2627 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2629 * lisp.h (eassert): Assume C89 or later.
2630 This removes the need for CHECK.
2631 (CHECK): Remove. Its comments about always evaluating its
2632 argument were confusing, as 'eassert' typically does not evaluate
2635 * coding.c (produce_chars): Use ptrdiff_t, not int.
2637 * xterm.c (x_draw_underwave): Check for integer overflow.
2638 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2807 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
2809 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
2811 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2812 * alloc.c (make_number) [!defined make_number]:
2813 Remove, as lisp.h always defines this now.
2814 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
2815 (roundup_size): Verify that it is a power of 2.
2816 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
2817 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
2818 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
2819 -DUSE_LSB_TAG=0, to override the automatically-selected default.
2820 USE_LSB_TAG now is always defined to be either 0 or 1.
2822 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2823 code works fine either way, and efficiency is not a concern here,
2824 as the union type is for debugging, not for production.
2825 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2826 Use an inline function on all platforms when using the union type,
2827 since this is simpler and 'static inline' can be used portably
2829 (LISP_INITIALLY_ZERO): New macro.
2830 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2831 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
2833 2012-06-12 Glenn Morris <rgm@gnu.org>

2848 MagickMergeImageLayers is undefined. Use pixel pusher loop if
2849 MagickExportImagePixels is undefined.

2857 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
2858 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
2859 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
2860 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
2862 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
2864 * alloc.c (make_byte_code): New function.

2897 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
2899 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
2900 dbus_type_is_basic if available.
2901 (xd_extract_signed, xd_extract_unsigned): Rename from
2902 extract_signed and extract_unsigned, respectively. Adapt callers.
2904 2012-06-09 Chong Yidong <cyd@gnu.org>
2906 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).
2908 * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive
2911 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
2913 * xdisp.c (vmessage): Treat frame message as multibyte.
2914 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2915 would generate the diagnostic "Making \302\247 buffer-local while
2918 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2920 * dispnew.c (showing_window_margins_p): Undo last change, which

2931 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
2933 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
2934 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2936 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2938 * alloc.c (allocate_vectorlike): Fix last change.
2940 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2942 Block-based vector allocation of small vectors.
2943 * lisp.h (struct vectorlike_header): New field `nbytes',
2944 adjust comment accordingly.
2945 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
2946 to denote vector blocks. Adjust users (live_vector_p,
2947 mark_maybe_pointer, valid_lisp_object_p) accordingly.
2948 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
2949 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
2950 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
2951 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
2952 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

2967 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2969 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2971 * doprnt.c (doprnt): Truncate multibyte char correctly.
2972 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2973 would mishandle a string argument "Xc" if X was a multibyte
2974 character of length 2: it would truncate after X's first byte
2975 rather than including all of X.
2977 2012-06-06 Chong Yidong <cyd@gnu.org>
2979 * buffer.c (word_wrap): Doc fix.
2981 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

3026 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3028 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3029 Convert pctcpu and pctmem to Lisp float properly.
3030 Let the compiler fold better, as 100.0/0x8000 is exact.
3032 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3034 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3037 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3039 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3041 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3043 For a 'struct window', replace some Lisp_Object fields to
3044 bitfields where appropriate, remove unused fields.
3045 * window.h (struct window): Remove unused 'last_mark_x' and
3046 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3047 change it's type from Lisp_Object to bitfield.
3048 Change type of 'force_start', 'optional_new_start',
3049 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3050 fields from Lisp_Object to bitfield. Adjust users accordingly.
3052 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3054 Pacify gcc -Wdouble-precision when using Xaw.
3055 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3056 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3057 Use 'float' consistently, rather than 'float' in most places
3058 and 'double' in a couple of places.
3060 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3062 * xdisp.c (handle_stop): Detect whether we have overlay strings
3063 loaded by testing it->current.overlay_string_index to be
3064 non-negative, instead of checking whether n_overlay_strings is
3065 positive. (Bug#11587)
3067 2012-05-31 Chong Yidong <cyd@gnu.org>
3069 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3071 * doc.c (Fsubstitute_command_keys): Doc fix.
3073 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3075 * search.c (search_buffer): Remove calls to
3076 r_alloc_inhibit_buffer_relocation, as it is now called by
3077 maybe_unify_char, which was the cause of relocation of buffer text
3080 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3082 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3083 for the duration of call to load_charset, to avoid problems with
3084 callers of maybe_unify_char that access buffer text through C
3087 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3088 decrement the inhibition flag, instead of just setting or
3091 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3093 Remove obsolete '#define static' cruft.
3094 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3095 This #undef was "temporary" in 2000; it is no longer needed
3096 now that '#define static' has gone away.
3097 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3098 (gray_bitmap_bits): Remove; no longer needed.
3099 All uses replaced with definiens.
3100 * xterm.c: Include "bitmaps/gray.xbm".
3102 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3104 Clean up __executable_start, monstartup when --enable-profiling.
3105 The following changes affect the code only when profiling.
3106 * dispnew.c (__executable_start): Rename from safe_bcopy.
3107 Define only on platforms that need it.
3108 * emacs.c: Include <sys/gmon.h> when profiling.
3109 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3110 (__executable_start): Remove decl, since lisp.h does it now.
3111 (safe_bcopy): Remove decl; no longer has that name.
3112 (main): Coalesce #if into single bit of code, for simplicity.
3113 Cast pointers to uintptr_t, since standard libraries want integers

3138 * lread.c (read1): Tiny simplification.
3140 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3142 Do not create empty overlays with the evaporate property (Bug#9642).
3143 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3144 Bug#9642, but explicitly check that the buffer the overlay would
3145 be moved to is live and rearrange lines to make sure that errors
3146 will not put the overlay in an inconsistent state.
3147 (Fdelete_overlay): Cosmetics.
3149 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3151 * w32term.c (my_bring_window_to_top): New function.
3152 (x_raise_frame): Use handle returned by DeferWindowPos, which
3153 could be different from the original one.

3157 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3158 by calling BringWindowToTop.

3163 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3165 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3166 This avoids undefined behavior that might cause the eassert
3167 to not catch an out-of-range value.
3169 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3171 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3183 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3185 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3186 Only r_alloc_inhibit_buffer_relocation needed to be added;
3187 the others were already declared.
3189 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3190 before checking whether it's out of range. Put the check inside
3192 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3194 2012-05-27 Ken Brown <kbrown@cornell.edu>
3196 * callproc.c (Fcall_process): Restore a line that was accidentally
3197 commented out in the 2011-02-13 change (bug#11547).

3201 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3202 defined on ralloc.c.
3204 * buffer.c [REL_ALLOC]: Remove prototypes of
3205 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3206 they are now on lisp.h.
3208 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3210 * search.c (search_buffer): Use it to inhibit relocation of buffer
3211 text while re_search_2 is doing its job, because re_search_2 is
3212 passed C pointers to buffer text. (Bug#11519)
3214 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3217 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3218 state after an additional call to move_it_in_display_line_to, keep
3219 the values of it->max_ascent and it->max_descent found for the
3221 (pos_visible_p): Revert the comparison against bottom_y to what it
3222 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3225 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3227 Fix coding-related core dumps with gcc -ftrapv.
3228 The code was computing A - B, where A and B are pointers, and B is
3229 random garbage. This can lead to core dumps on platforms that
3230 have special pointer registers, and it also leads to core dumps on
3231 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3232 A - B only when B is initialized properly.
3233 * coding.c (coding_set_source, coding_set_destination): Return void.
3234 (coding_change_source, coding_change_destinations): New functions,
3235 with the old behaviors of coding_set_source and coding_set_destination.
3236 All callers that need an offset changed to use these new functions.
3238 2012-05-26 Glenn Morris <rgm@gnu.org>
3240 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3242 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3244 Extend mouse support on W32 text-mode console.
3245 * xdisp.c (draw_row_with_mouse_face):
3246 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3248 * w32console.c: Include window.h.
3249 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3251 (initialize_w32_display): Initialize mouse-highlight data.
3253 * w32inevt.c: Include termchar.h and window.h.
3254 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3255 moves, call note_mouse_highlight. If help_echo changed, call
3256 gen_help_event to produce help-echo message in the echo area.
3257 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3260 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3262 * lread.c (read1): Simplify slightly to avoid an overflow warning
3263 with GCC 4.7.0 on x86-64.
3265 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3267 * bidi.c (bidi_mirror_char): Revert last change: an int is
3268 definitely wide enough here.
3270 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3272 Fix integer width and related bugs (Bug#9874).
3273 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3274 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3275 (string_bytes, check_sblock, allocate_string_data):
3276 (compact_small_strings, Fmake_bool_vector, make_string)
3277 (make_unibyte_string, make_multibyte_string)
3278 (make_string_from_bytes, make_specified_string)
3279 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3280 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)

3304 (Foverlay_recenter, last_overlay_modification_hooks_used)
3305 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3306 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3307 (validate_region): Omit unnecessary test for b <= e,
3308 since that's guaranteed by the previous test.

3310 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3311 (report_overlay_modification):

3313 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3317 * buffer.h: Adjust decls to match defn changes elsewhere.

3322 not int, to avoid needless 32-bit limit on 64-bit hosts.
3323 (exec_byte_code): Use tighter memory-full test, one that checks
3324 for alloca overflow. Don't compute the address of the object just
3325 before an array, as that's not portable. Use EMACS_INT, not
3326 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3327 * callint.c (Fcall_interactively):
3328 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3341 (casify_object): Avoid integer overflow when overallocating buffer.
3342 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3345 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3346 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3349 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3350 For CCL_MapSingle, check that content and value are in int range.

3352 Check that Vcode_version_map_vector is a vector.
3353 (resolve_symbol_ccl_program): Check that vector header is in range.
3354 Always copy the vector, so that we can check its contents reliably
3355 now rather than having to recheck each instruction as it's being
3356 executed. Check that vector words fit in 'int'.
3357 (ccl_get_compiled_code, Fregister_ccl_program)
3358 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3359 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3361 contents are in range.
3362 (Fccl_execute_on_string): Check that status is in range.
3363 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3364 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3365 Accept and return EMACS_INT, not int, because callers can pass values

3372 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3374 avoid mishandling large integers.

3385 Don't rely on undefined behavior with signed left shift overflow.
3386 Don't assume unsigned int fits into fixnum, or that fixnum fits
3387 into unsigned int. Don't require max_code to be a valid fixnum;
3388 that's not true for gb10830 4-byte on a 32-bit host. Allow
3389 invalid_code to be a cons, for the same reason. Require code_offset
3390 to be a character. Avoid int overflow if max_char is close
3392 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3393 this is intended anyway and avoids some undefined behavior.
3394 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3395 INDEX_TO_CODE_POINT, as that's what it expects.
3396 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3397 * charset.h (DECODE_CHAR): Return int, not unsigned;
3398 this is what was intended anyway, and it avoids undefined behavior.
3399 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3400 integer-overflow issues.
3401 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3402 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3403 where the argument is EMACS_INT, and this behavior is not intended.
3404 * chartab.c (Fmake_char_table, Fset_char_table_range)
3405 (uniprop_get_decoder, uniprop_get_encoder):
3406 Don't assume fixnum fits in int.
3407 * cmds.c (move_point): New function, that does the gist of
3408 Fforward_char and Fbackward_char, but does so while checking
3409 for integer overflow more accurately.
3410 (Fforward_char, Fbackward_char): Use it.
3411 (Fforward_line, Fend_of_line, internal_self_insert)
3412 (internal_self_insert):
3413 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4069 rather than rolling our own approximation.
4070 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4072 2012-05-25 Glenn Morris <rgm@gnu.org>
4074 * lisp.mk (lisp): Update for more files being compiled now.
4076 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
4078 * lread.c: Remove `read_pure' which makes no difference.
4079 (read_pure): Remove var.
4080 (unreadpure): Remove function.
4081 (readevalloop): Don't call read_list with -1 flag.
4082 (read1, read_vector): Don't test read_pure any more.
4083 (read_list): Simplify.

4094 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
4096 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4099 This directory predates autoconf and is no longer needed nowadays.
4100 Move its few remaining bits of functionality to where they're needed.
4101 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
4102 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

4106 * lisp.h (USE_LSB_TAG):
4107 * mem-limits.h (EXCEEDS_LISP_PTR):
4108 Use VAL_MAX, not VALBITS, in #if.
4109 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4110 (EMACS_UINT): Define unconditionally now.
4111 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4112 (BITS_PER_EMACS_INT): New constants, replacing
4113 what used to be in config.h, but not useful in #if.
4114 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4115 define them any more.
4116 (VAL_MAX): New macro.
4118 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4119 BITS_PER_EMACS_INT, in #if.
4120 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4121 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4122 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4123 * s/ms-w32.h (DATA_START):
4124 Move here from removed file m/intel386.h.
4125 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4126 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4128 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4130 Assume C89 or later.
4131 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

4138 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4139 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4140 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4141 * xterm.c (input_signal_count): Assume volatile works.
4143 2012-05-21 Ken Brown <kbrown@cornell.edu>
4145 * xgselect.c (xg_select): Fix first argument in call to 'select'
4148 2012-05-20 Ken Brown <kbrown@cornell.edu>
4150 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4151 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4153 2012-05-19 Ken Brown <kbrown@cornell.edu>
4155 * xfns.c (x_in_use): Remove `static' qualifier.
4156 * xterm.h (x_in_use): Declare.
4157 * xgselect.c: Include xterm.h.
4158 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4159 and `display_arg' (bug#9754).
4161 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4163 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4165 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4166 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4168 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4170 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4172 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4173 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4175 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4176 reference to image_cache->refcount.
4177 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4179 2012-05-17 Juri Linkov <juri@jurta.org>
4181 * search.c (Fword_search_regexp, Fword_search_backward)
4182 (Fword_search_forward, Fword_search_backward_lax)
4183 (Fword_search_forward_lax): Move functions to isearch.el
4184 (bug#10145, bug#11381).
4186 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4188 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4190 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4192 * lread.c (init_obarray): Declare Qt and Qnil as special.
4194 2012-05-14 Glenn Morris <rgm@gnu.org>
4196 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4197 Put "libexec" before "bin", for the sake of init_callproc_1.
4199 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4201 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4203 * unexaix.c: Port to more-recent AIX compilers.
4204 (report_error, report_error_1, make_hdr, copy_sym)
4205 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4206 Make arguments const char *, not char *, to avoid violations of C
4207 standard and to fix some AIX warnings reported by Gilles Pion.
4209 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4211 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4212 already have overlays loaded.
4213 (handle_single_display_spec): Before returning without displaying
4214 fringe bitmap, synchronize the bidi iterator with the main display
4215 iterator, by calling iterate_out_of_display_property.
4216 (iterate_out_of_display_property): Detect buffer iteration by
4217 testing that it->string is a Lisp string.
4218 (get_next_display_element): When the current object is exhausted,
4219 and there's something on it->stack, call set_iterator_to_next to
4220 proceed with what's on the stack, instead of returning zero.
4221 (set_iterator_to_next): If called at the end of a Lisp string,
4222 proceed to consider_string_end without incrementing string
4223 position. Don't increment display vector index past the end of
4224 the display vector. (Bug#11417)
4225 (pos_visible_p): Don't report a position visible when move_it_to
4226 stopped at the last line of window, which happens to be scanned
4227 backwards by the bidi iteration. (Bug#11464)
4229 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4231 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4232 and right-margin display specs even if the spec is invalid or we
4233 are on a TTY, and thus unable to display on the fringes.
4234 That's because the text with the property will not be displayed anyway,
4235 so we need to signal to the caller that this is a "replacing"
4236 display spec. This fixes display when the spec is invalid or we
4239 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4241 * unexaix.c (make_hdr): Fix typo in prototype.
4242 This bug broke the build on AIX. Problem reported by Gilles Pion.
4244 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4246 * keyboard.c (kbd_buffer_get_event): Read special events also in
4247 batch mode. (Bug#11415)
4249 2012-05-12 Glenn Morris <rgm@gnu.org>
4251 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4253 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4255 * lisp.mk (lisp): Add newcomment.elc.
4257 2012-05-12 Glenn Morris <rgm@gnu.org>
4259 * Makefile.in (MKDIR_P): New, set by configure.
4260 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4262 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4264 Remove unused function hourglass_started.
4265 * dispextern.h (hourglass_started):
4266 * w32fns.c (hourglass_started):
4267 * xdisp.c (hourglass_started): Remove.
4269 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4271 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4272 Update dependencies.
4274 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4276 * xgselect.c (xg_select): Put maxfds+1 into a var.
4277 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4279 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4281 2012-05-10 Dave Abrahams <dave@boostpro.com>
4283 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4284 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4286 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4288 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4289 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4290 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4291 Initialize xd_registered_buses.
4293 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4295 Untag more efficiently if USE_LSB_TAG.
4296 This is based on a proposal by YAMAMOTO Mitsuharu in
4297 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4298 For an admittedly artificial (nth 8000 longlist) benchmark on
4299 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4300 Emacs's overall text size by 1%.
4301 * lisp.h (XUNTAG): New macro.
4302 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4303 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4304 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4305 * eval.c (Fautoload):
4306 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4307 * frame.h (XFRAME): Use XUNTAG.
4309 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4310 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4311 Remove unportable assumptions about print widths of types like
4313 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4314 intptr_t when converting between pointer and integer, to avoid GCC
4315 warnings about wrong width.
4317 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4319 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4320 stack for each reader_thread, instead of defaulting to 8MB
4321 determined by the linker. This avoids failures in creating
4322 subprocesses on Windows 7, see the discussion in this thread:
4323 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4325 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4327 Fix up display of the *Minibuf-0* buffer in the mini window.
4328 * keyboard.c (read_char): Don't clear the echo area if there's no
4330 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4331 contents of *Minibuf-0*) if there's no message displayed in its stead.
4333 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4335 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4338 2012-05-06 Chong Yidong <cyd@gnu.org>
4340 * lisp.mk (lisp): Update.
4342 2012-05-05 Jim Meyering <meyering@redhat.com>
4344 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4346 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4348 * data.c (PUT_ERROR): New macro.
4349 (syms_of_data): Use it. Add new error type `user-error'.
4350 * undo.c (user_error): New function.
4351 (Fprimitive_undo): Use it.
4352 * print.c (print_error_message): Adjust print style for `user-error'.
4353 * keyboard.c (user_error): New function.
4354 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4356 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4358 Do not limit current-time-string to years 1000..9999.
4359 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4360 (Fcurrent_time_string): Support any year that is supported by the
4361 underlying localtime representation. Don't use asctime, as it
4362 has undefined behavior for years outside the range -999..9999.
4364 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4366 Fix race conditions involving setenv, gmtime, localtime, asctime.
4367 Without this fix, interrupts could mess up code that uses these
4368 nonreentrant functions, since setting TZ invalidates existing
4369 tm_zone or tzname values, and since most of these functions return
4370 pointers to static storage.
4371 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4372 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4373 Grow the critical sections to include not just invoking
4374 localtime/gmtime, but also accessing these functions' results
4375 including their tm_zone values if any, and any related TZ setting.
4376 (format_time_string): Last arg is now struct tm *, not struct tm **,
4377 so that the struct tm is saved in the critical section.
4378 All callers changed. Simplify allocation of initial buffer, partly
4379 motivated by the fact that memory allocation needs to be outside
4380 the critical section.
4382 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4384 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4385 with RESET_INTERVAL.
4387 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4388 Remove duplicated buffer name initialization.
4390 2012-05-02 Jim Meyering <jim@meyering.net>
4392 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4394 * xfns.c (x_window): Use xstrdup (Bug#11375).
4396 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4398 * xdisp.c (pos_visible_p): If already at a newline from the
4399 display string before the 'while' loop, don't walk back the glyphs
4400 from it3.glyph_row. Solves assertion violation when the display
4401 string begins with a newline (egg.el). (Bug#11367)
4403 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4405 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4408 2012-05-01 Glenn Morris <rgm@gnu.org>
4410 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4411 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4412 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4413 All were removed before 23.1.
4415 * dispnew.c: Remove HAVE_LIBNCURSES test;
4416 it is always true on relevant platforms.
4418 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4419 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4421 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

4429 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4431 Do not avoid creating empty evaporating overlays (Bug#9642).
4432 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4433 That is, do not delete an evaporating overlay if it becomes
4434 empty after its bounds are adjusted to fit within its buffer.
4435 This fix caused other problems, and I'm reverting it until we get
4436 to the bottom of them.
4438 2012-04-27 Chong Yidong <cyd@gnu.org>
4440 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4442 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4444 * xdisp.c (pos_visible_p): If the window start position is beyond
4445 ZV, start the display from buffer beginning. Prevents assertion
4446 violation in init_iterator when the minibuffer window is scrolled
4449 * window.c (window_scroll_pixel_based): Likewise.
4451 2012-04-27 Chong Yidong <cyd@gnu.org>

4465 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4467 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4468 display element, check also the underlying string or buffer
4469 character. (Bug#11341)
4471 * w32menu.c: Include w32heap.h.
4472 (add_menu_item): If the call to AppendMenuW (via
4473 unicode_append_menu) fails, disable Unicode menus only if we are
4474 running on Windows 9X/Me.
4476 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4478 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4481 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4483 * keyboard.c (read_char): Don't wipe echo area for select window
4484 events: These might get delayed via `mouse-autoselect-window'

4489 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4490 manipulation of :loaded-from data.
4492 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4494 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4495 now a cons (bug#11311).
4497 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4499 Do not create empty overlays with the evaporate property (Bug#9642).
4500 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4501 if it becomes empty after its bounds are adjusted to fit within
4502 its buffer. Without this fix, in a nonempty buffer (let ((o
4503 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4504 yields an empty overlay that has the evaporate property, which is
4505 not supposed to happen.
4507 Fix minor GTK3 problems found by static checking.
4508 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4523 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4525 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4527 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4528 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4529 (__malloc_size_t, __malloc_ptrdiff_t):

4542 Define using prototypes, not old style.
4543 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4544 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

4609 since the two debugging options are incompatible.
4610 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4612 (mem_init, mem_insert, mem_insert_fixup):
4613 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4622 * sysdep.c [__FreeBSD__]: Minor cleanups.
4623 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4624 Use Emacs indenting style more consistently. Avoid some casts.
4625 Use 'double' consistently rather than mixing 'float' and 'double'.
4627 2012-04-21 Eduard Wiebe <usenet@pusto.de>
4629 * sysdep.c (list_system_processes, system_process_attributes):
4630 Add implementation for FreeBSD (Bug#5243).

4645 (print_object): Check for cycles even when print-circle is nil and
4646 print-gensym is t, but only check print_depth if print-circle is nil.
4648 2012-04-20 Chong Yidong <cyd@gnu.org>
4650 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4651 set the status to "failed" and ensure that sentinel is run.

4666 farther than the first row after the header line, if any.
4667 Don't consider the header-line row as "partially visible", even if

4706 New extern decls, to avoid calling undeclared functions.
4707 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4708 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4709 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4710 (NEED_MEM_INSERT): New macro.
4711 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4712 Remove one incorrect comment and fix another.

4724 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
4725 [REL_ALLOC]: ... to here, to check interface.
4726 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4727 Remove decls. This fixes an "It stinks!".
4729 * alloc.c (which_symbols): Fix alignment issue / type clash.
4731 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4733 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4750 Remove definition of GC_MARK_STACK, since the default now works.
4751 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4752 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4753 no longer the default.
4754 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4756 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4758 * lread.c (lisp_file_lexically_bound_p):

4779 2012-04-11 Daniel Colascione <dancol@dancol.org>
4781 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4782 against is gone. It's better to use vfork now so that when Cygwin
4783 gains a new, working vfork, we use it automatically (bug#10398).
4785 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4787 * window.c (save_window_save): Obey window-point-insertion-type.

4806 being loaded (bug#10424).
4808 2012-04-09 Glenn Morris <rgm@gnu.org>
4810 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4811 not just in the obarray, before snarfing them. (Bug#11036)

4823 Add convenience `GNUTLS_LOG2i' macro.
4825 * gnutls.c (gnutls_log_function2i): Convenience log function.
4826 (emacs_gnutls_read): Use new log functions,
4827 `gnutls_handshakes_tried' process member, and
4828 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4829 attempts per process (connection).
4831 2012-04-09 Chong Yidong <cyd@gnu.org>

4838 * minibuf.c (Fread_variable): Callers changed.
4840 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4842 * xdisp.c (set_cursor_from_row): If the display string appears in
4843 the buffer at position that is closer to point than the position
4844 after the display string, display the cursor on the first glyph of
4845 the display string. Fixes cursor display when a 'display' text
4846 property immediately follows invisible text. (Bug#11094)
4848 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4850 composite.c: use 'double' consistently
4851 * composite.c (get_composition_id): Use 'double' consistently
4852 instead of converting 'float' to 'double' and vice versa; this is
4853 easier to understand and avoids a GCC warning.
4855 2012-04-09 Glenn Morris <rgm@gnu.org>
4857 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4858 preparation for dumping it with emacs. (Bug#4789)

4880 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4881 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4882 objects, as mark_maybe_pointer will catch them otherwise.
4883 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4884 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

4902 [!WINDOWSNT]: New macros.
4903 (init_libxml2_functions, libxml2_loaded_p): New functions.
4904 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4905 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4906 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4907 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4909 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4910 Call init_libxml2_functions before calling libxml2 functions.

4915 xmlCleanupParser directly.
4917 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4919 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4921 * indent.c (Fvertical_motion): If there is a display string at
4922 point, use it.vpos to compute how many lines to backtrack after

4927 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4928 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4929 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4930 macros related to unification of CJK characters. For the details,
4931 see the discussion following the message here:
4932 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4934 2012-04-04 Chong Yidong <cyd@gnu.org>
4936 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4938 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4940 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

4945 * w32menu.c (is_simple_dialog): Properly check lisp types.
4948 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4950 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4951 position we get to after a call to move_it_to fails the
4952 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4953 only if we wind up in a string from display property. (Bug#11063)
4955 * window.c (Fdelete_other_windows_internal): Invalidate the row
4956 and column information about mouse highlight, so that redisplay
4957 restores it after reallocating the glyph matrices. (Bug#7464)
4959 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4960 string comes from a `display' text property, use the buffer
4961 position of that property as if we actually saw that position in
4963 (move_it_by_lines): Remove the assertion that
4964 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4965 violated when there's a before-string at the beginning of a line.
4968 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4970 * xdisp.c (append_space_for_newline): If the default face was
4971 remapped, use the remapped face for the appended newline.
4972 (extend_face_to_end_of_line): Use the remapped default face for
4973 extending the face to the end of the line.
4974 (display_line): Call extend_face_to_end_of_line when the default
4975 face was remapped. (Bug#11068)
4977 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4979 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

4990 2012-03-26 Kenichi Handa <handa@m17n.org>
4992 * dispextern.h (struct glyph): Fix previous change. Change the
4993 bit length of glyphless.ch to 25 (Bug#11082).
4995 2012-03-26 Chong Yidong <cyd@gnu.org>
4997 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4998 (command_loop_1): Use it; inhibit selection update for
4999 handle-select-window too (Bug#8996).
5001 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5003 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5005 2012-03-25 Kenichi Handa <handa@m17n.org>
5007 * dispextern.h (struct glyph): Change the bit length of
5008 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5010 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5012 * s/ms-w32.h (tzname): Include time.h before redirecting to
5013 _tzname. Fixes the MSVC build. (Bug#9960)
5015 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5017 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5020 * xterm.c (XTread_socket): Only modify handling_signal if
5021 !SYNC_INPUT. (Bug#11080)
5023 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5025 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5026 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5027 when fetching a multibyte character consumes more bytes than
5028 CHAR_BYTES returns, due to unification of CJK characters in
5029 string_char. (Bug#11073)
5031 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5033 * process.c (wait_reading_process_output): Handle pty disconnect
5034 by refraining from sending oneself a SIGCHLD (bug#10933).
5036 2012-03-22 Chong Yidong <cyd@gnu.org>

5049 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5051 * w32proc.c (Fw32_set_console_codepage)
5052 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5057 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5058 to reflect default non-nil value of redisplay-dont-pause.
5060 2012-03-19 Kenichi Handa <handa@m17n.org>

5063 it fit in a valid range (Bug#11003).
5065 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5067 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5068 that is not from display property, accept the row as a "cursor
5069 row" if one of the string's character has a non-nil `cursor'
5070 property. Fixes cursor positioning when there are newlines in
5071 overlay strings, e.g. in icomplete.el. (Bug#11035)
5073 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5075 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5077 2012-03-12 Chong Yidong <cyd@gnu.org>
5079 * eval.c (inhibit_lisp_code): Rename from
5080 inhibit_window_configuration_change_hook; move from window.c.
5082 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5083 * window.c (run_window_configuration_change_hook)
5084 (syms_of_window): Callers changed.
5086 2012-03-11 Chong Yidong <cyd@gnu.org>

5095 is visible (Bug#10955).
5097 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5099 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5101 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5103 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5104 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5107 2012-03-03 Glenn Morris <rgm@gnu.org>
5109 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5111 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5113 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5114 position past the first glyph_row that ends at ZV. (Bug#10902)
5115 (redisplay_window, next_element_from_string): Fix typos in
5117 (redisplay_window): Pass to move_it_vertically the margin in
5118 pixels, not in screen lines.
5120 2012-03-02 Glenn Morris <rgm@gnu.org>
5122 * buffer.c (buffer-list-update-hook): Doc fix.
5124 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5126 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5127 push_it before setting up the iterator for the first overlay
5128 string, even if we have an empty string loaded.
5129 (next_overlay_string): If there's an empty string on the iterator
5130 stack, pop the stack. (Bug#10903)
5132 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5134 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5135 Suggested by Stefan Monnier in
5136 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5137 * alloc.c (widen_to_Lisp_Object): New static function.
5138 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5139 and widening them to Lisp_Objects. This would work even if
5140 USE_LSB_TAG is defined and wide integers are used, which might
5141 happen in a future version of Emacs.
5143 2012-02-25 Chong Yidong <cyd@gnu.org>
5145 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5148 * xselect.c (Fx_selection_exists_p): Doc fix.
5149 (x_clipboard_manager_save_all): Print an informative message
5150 before saving to clipboard manager.
5152 2012-02-24 Chong Yidong <cyd@gnu.org>
5154 * keyboard.c (process_special_events): Handle all X selection
5155 requests in kbd_buffer, not just the next one (Bug#8869).
5157 2012-02-23 Chong Yidong <cyd@gnu.org>
5159 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5160 call when setting menu-bar-lines and tool-bar-lines parameters.
5161 (unwind_create_frame_1): New helper function.
5163 * window.c (inhibit_window_configuration_change_hook): New var.
5164 (run_window_configuration_change_hook): Obey it.
5165 (syms_of_window): Initialize it.
5167 2012-02-22 Chong Yidong <cyd@gnu.org>
5169 * xterm.c (x_draw_image_relief): Add missing type check for
5170 Vtool_bar_button_margin (Bug#10743).

5174 * fileio.c (Vfile_name_handler_alist): Doc fix.
5176 * buffer.c (Fget_file_buffer): Protect against invalid file
5177 handler return value.
5179 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5181 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5182 when computing $valmask.
5184 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5185 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5186 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5187 It's useless in that case, and it can cause problems on hosts
5188 that allocate halves of EMACS_INT values separately.
5189 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5190 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5191 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5192 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5193 it avoids undefined behavior on hosts where shifting right by more
5194 than the word width has undefined behavior.
5196 2012-02-19 Chong Yidong <cyd@gnu.org>
5198 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5199 (Funhandled_file_name_directory, Ffile_name_as_directory)
5200 (Fdirectory_file_name, Fexpand_file_name)
5201 (Fsubstitute_in_file_name): Protect against invalid file handler
5202 return values (Bug#10845).
5204 2012-02-18 Eli Zaretskii <eliz@gnu.org>

5216 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5218 2012-02-15 Chong Yidong <cyd@gnu.org>
5220 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5221 marked as special. Also, starting docstrings with * is obsolete.

5232 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5234 * keymap.c (Fsingle_key_description): Handle char ranges.
5236 2012-02-12 Chong Yidong <cyd@gnu.org>
5238 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5239 as that creates a dangerous corner case.
5241 * window.c (Fdelete_window_internal): Invalidate the mouse
5242 highlight (Bug#9904).
5244 2012-02-12 Glenn Morris <rgm@gnu.org>
5246 * xselect.c (Fx_own_selection_internal)
5247 (Fx_get_selection_internal, Fx_disown_selection_internal)
5248 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5249 * nsselect.m (Fx_own_selection_internal)
5250 (Fx_disown_selection_internal, Fx_selection_exists_p)
5251 (Fx_selection_owner_p, Fx_get_selection_internal):
5252 Sync docs and argument specs with the xselect.c versions.
5254 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5256 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5258 2012-02-11 Eli Zaretskii <eliz@gnu.org>

5274 2012-02-07 Chong Yidong <cyd@gnu.org>
5276 * buffer.c (Fbuffer_local_variables)
5277 (buffer_lisp_local_variables): Handle unbound vars correctly;
5278 don't let Qunbound leak into Lisp.
5280 2012-02-07 Glenn Morris <rgm@gnu.org>
5282 * image.c (Fimagemagick_types): Doc fix.
5284 * image.c (imagemagick-render-type): Change it from a lisp object
5285 to an integer. Move the doc here from the lisp manual.

5290 * doc.c (store_function_docstring): Avoid applying docstring of
5291 alias to base function (Bug#2603).
5293 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5295 * .gdbinit (pp1, pv1): Remove redundant defines.
5298 2012-02-04 Chong Yidong <cyd@gnu.org>
5300 * nsterm.m: Declare a global (Bug#10694).
5302 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5304 * w32.c (get_emacs_configuration_options):
5305 Include --enable-checking, if specified, in the return value.
5307 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5309 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5310 after rounding frame sizes. (Bug#9723)
5312 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5314 * keyboard.c (adjust_point_for_property): Don't position point
5315 before BEGV. (Bug#10696)
5317 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5319 Handle overflow when computing char display width (Bug#9496).
5320 * character.c (char_width): Return EMACS_INT, not int.
5321 (char_width, c_string_width): Check for overflow when
5322 computing the width; this is possible now that individual
5323 characters can have unbounded width. Problem introduced
5324 by merge from Emacs 23 on 2012-01-19.
5326 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5328 * dbusbind.c (Fdbus_register_method): Mention the return value

5341 2012-02-02 Kenichi Handa <handa@m17n.org>
5343 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5344 0, do not call append_composite_glyph.
5346 2012-02-02 Kenichi Handa <handa@m17n.org>
5348 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5350 (x_produce_glyphs): If the component of a composition is a null
5351 string, set it->pixel_width to 1 to avoid zero-width glyph.
5353 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5355 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5356 first 2 arguments are identical. This makes inserting large

5888 * xdisp.c (redisplay_window): If cursor row is not fully visible
5889 after recentering, and scroll-conservatively is set to a large
5890 number, scroll window by a few more lines to make the cursor fully
5891 visible and out of scroll-margin. (Bug#10105)
5892 (start_display): Don't move to the next line if the display should
5893 start at a newline that is part of a display vector or an overlay

5977 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5978 is set, removing the need for VIRT_ADDRESS_VARIES.
5979 (PURE_P): Use a more-efficient implementation that needs just one
5980 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5981 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5982 to 4 (xorl, subq, cmpq, setbe).
5983 * alloc.c (pure): Always extern now, since that's the
5984 VIRT_ADDR_VARIES behavior.
5985 (PURE_POINTER_P): Use a single comparison, not two, for
5986 consistency with the new puresize.h.
5987 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

5994 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5995 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5996 behave as if the cursor position were at the window margin.
5998 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5999 and the cursor position is out of bounds, behave as if the cursor
6000 position were at the window margin. (Bug#10075)
6002 2011-11-18 Chong Yidong <cyd@gnu.org>
6004 * window.c (Fwindow_combination_limit): Make first argument

6026 compute_line_metrics.
6027 (compute_line_metrics): Call row_hash, instead of computing the
6030 * dispnew.c (verify_row_hash): Call row_hash for computing the
6031 hash code of a row, instead of duplicating code from xdisp.c.
6033 * dispextern.h (row_hash): Add prototype.
6035 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6064 (Fset_window_configuration, save_window_save): Rename all
6065 occurrences of window_nest to window_combination_limit.
6067 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6069 * image.c (imagemagick_load_image): Fix typo.
6071 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6073 * xdisp.c (display_line): Move the call to
6074 highlight_trailing_whitespace before the call to
6075 compute_line_metrics, since the latter needs to see the final
6076 faces of all the glyphs to compute ROW's hash value.
6077 Fixes assertion violations in row_equal_p. (Bug#10035)
6079 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6081 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6086 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6087 with user-defined heap size. Bump the default size of the temacs
6088 heap to 27MB, to avoid memory warning when running temacs.
6089 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6091 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6138 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6140 Avoid some portability problems by eschewing 'extern inline' functions.
6141 The trivial performance wins aren't worth the portability hassles; see
6142 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6144 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6146 (window_box_right, window_box_right_offset): Undo previous change,
6147 by removing the "extern"s.
6148 * intervals.c (adjust_intervals_for_insertion)
6149 (adjust_intervals_for_deletion): Undo previous change,
6150 making these static again.
6151 (offset_intervals, temp_set_point_both, temp_set_point)
6152 (copy_intervals_to_string): No longer inline.
6153 * xdisp.c (window_text_bottom_y, window_box_width)

6218 (window_box_width, window_box_left, window_box_left_offset)
6219 (window_box_right, window_box_right_offset): Declare extern.
6220 Otherwise, these inline functions do not conform to C99 and
6221 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6222 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6223 * intervals.c (adjust_intervals_for_insertion)
6224 (adjust_intervals_for_deletion): Now extern, because otherwise the

6226 (static_offset_intervals): Remove.
6227 (offset_intervals): Rewrite using the old contents of
6228 static_offset_intervals. The old version didn't conform to C99
6229 because an extern inline function contained a reference to an
6230 identifier with static linkage.
6232 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6234 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6252 (Fwindow_vscroll): Doc fix.
6253 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6254 argument, since it makes no sense to pass a live window and for
6255 consistency with window-child.

6283 (unwind_create_frame): New function (Bug#9943).
6284 (Fx_create_frame): Restructure code to be more similar to the one in
6285 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6286 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6287 Move terminal->reference_count++ just before making the frame official

6291 (x_destroy_window): Move code to x_free_frame_resources.
6293 * xfns.c (unwind_create_frame): Fix comment.

6330 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
6332 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
6334 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6336 * xdisp.c (note_mouse_highlight): If either of
6337 previous/next-single-property-change returns nil, treat that as
6338 the beginning or the end of the buffer. (Bug#9955)
6340 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
6342 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
6343 label is not null (Bug#9951).
6344 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl

6354 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
6356 * w32fns.c (unwind_create_frame): If needed, free the glyph
6357 matrices of the partially constructed frame. (Bug#9943)
6358 * xfns.c (unwind_create_frame): Likewise.
6360 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6362 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6363 Don't stop backward scan on the continuation glyph, even though
6364 its CHARPOS is positive.
6365 (mouse_face_from_buffer_pos, note_mouse_highlight):
6366 Rename cover_string to disp_string.
6368 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6370 * window.c (temp_output_buffer_show): Don't use
6371 Vtemp_buffer_show_specifiers.
6372 (Vtemp_buffer_show_specifiers): Remove unused variable.
6374 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6376 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6377 past the beginning of the current glyph matrix.
6379 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6381 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6382 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6383 HAVE_GTK3 (Bug#9869).
6385 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6386 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6388 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6390 * xterm.c: Declare x_handle_net_wm_state to return int.
6391 (handle_one_xevent): Check if we are iconified but don't have
6392 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6393 (get_current_wm_state): Return non-zero if not hidden,
6394 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6395 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6396 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6397 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6399 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6401 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6402 so that this new function doesn't get optimized away by a
6403 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6405 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6407 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6409 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6411 Fix the `xbytecode' command.
6412 * .gdbinit (xprintbytestr): New command.
6413 (xwhichsymbols): Rename from `which'; all callers changed.
6414 (xbytecode): Print the byte-code string as well.
6416 2011-10-29 Kim Storm <storm@cua.dk>
6418 * alloc.c (which_symbols): New function.
6420 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6422 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6425 2011-10-29 Glenn Morris <rgm@gnu.org>
6427 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6428 Not clear what it was for, and it causes various bugs. (Bug#9839)
6430 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6432 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6433 possible random value that matches one of those tested as
6434 condition to clear the mouse face.
6436 2011-10-28 Chong Yidong <cyd@gnu.org>
6438 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6440 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6442 * window.c (make_window): Initialize phys_cursor_on_p.
6444 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6446 * lisp.h (struct Lisp_Symbol): Update comments.
6448 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6450 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6452 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6454 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6455 <oslsachem@gmail.com> for helping to debug this.
6457 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6458 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6459 (g_b_init_get_glyph_outline_w): New static variables.
6460 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6461 (GetGlyphOutlineW_Proc): New typedefs.
6462 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6463 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6465 (w32font_open_internal, compute_metrics):
6466 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6467 instead of calling the "wide" APIs directly.
6469 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6471 * w32.h (syms_of_w32font): Add prototype.
6473 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6475 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6476 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6477 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6478 (Fmove_to_window_line): Doc fix.
6480 2011-10-27 Chong Yidong <cyd@gnu.org>
6482 * process.c (make_process): Set gnutls_state to NULL.
6484 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6485 non-NULL, regardless of GNUTLS_INITSTAGE.
6486 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6487 an error. Set process slots as soon as we allocate them.
6489 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6491 2011-10-27 Chong Yidong <cyd@gnu.org>

6495 (Fgnutls_deinit, Fgnutls_boot): Use it.
6497 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6498 (deactivate_process): Call emacs_gnutls_deinit.
6500 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6503 * w32.c (sys_rename, w32_delayed_load):
6504 * w32font.c (fill_in_logfont):
6505 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6507 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6509 * w32fns.c (w32_default_color_map): New function,
6510 extracted from Fw32_default_color_map.
6511 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6513 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6515 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6517 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6519 * keyboard.c (test_undefined): New function (bug#9751).
6520 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6522 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6524 * sysdep.c (init_sys_modes): Fix the check for the controlling
6525 terminal (Bug#6649).
6527 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6529 * dispextern.h (struct bidi_it): New member next_en_type.
6531 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6532 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6533 current character, check also for next_en_type being WEAK_EN.
6534 (bidi_resolve_weak): Don't enter the expensive loop if the current
6535 position is before next_en_pos. Record the bidi type of the first
6536 non-ET, non-BN character we find, in addition to its position.
6537 (bidi_level_of_next_char): Invalidate next_en_type when
6538 next_en_pos is over-stepped.
6540 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6542 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6543 * editfns.c: Rewrite current-time-zone so that it invokes
6544 the equivalent of (format-time-string "%Z") to get the time zone name.
6545 This fixes a bug when the time zone name contains characters that
6546 need converting from the system time locale to Emacs internal format.
6547 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6548 that patch fixed format-time-string to do the conversion, but
6549 I forgot to fix current-time-zone.
6550 (format_time_string): New function, containing most of
6551 what Fformat_time_string used to contain.
6552 (Fformat_time_string): Rewrite in terms of format_time_string.
6553 This doesn't change this function's behavior.
6554 (current-time-zone): Rewrite to use format_time_string.
6555 This fixes the bug reported by Michael Schierl in
6556 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6557 Jason Rumney's 2007-06-07 change worked around this bug, but
6559 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6561 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6563 * xdisp.c (start_display): If the character at POS is displayed
6564 via a display vector, reset IT->current.dpvec_index to zero.
6565 (try_window_reusing_current_matrix): If a line ends in a display
6566 vector or the next line starts in a display vector, continue
6567 redrawing the window even though the character position of
6568 start_row was reached.
6571 2011-10-18 Chong Yidong <cyd@gnu.org>
6573 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6574 with nobreak-char-display too.
6576 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6578 Fix part 3 of bug#9771.
6579 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6580 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6581 non-neutral characters if the current character is a paragraph
6582 separator (a.k.a. Newline). This avoids running the same
6583 expensive loop twice, once when we consume the preceding newline
6584 and the other time when the line actually needs to be displayed.
6585 Avoid the loop when we see neutrals on the base embedding level
6586 following a character whose directionality is the same as the
6587 paragraph's. This avoids running the expensive loop when a line
6588 ends in a long sequence of neutrals, like control characters.
6589 Add assertion against STRONG_AL type. Slightly rearrange code
6590 that determines the type of a neutral given the first non-neutral
6592 (bidi_level_of_next_char): Set next_en_pos to zero when
6593 invalidating its info.
6595 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6597 * xdisp.c (push_display_prop): Determine whether to record string
6598 or buffer position by IT->string, not by IT->method. Allow
6599 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6600 (move_it_vertically_backward): Don't look for character position
6601 immediately after the newline when in a continuation line.
6604 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6606 * window.c (coordinates_in_window): Rewrite and delabelize
6607 vertical border check. (Bug#5357) (Bug#9618)
6609 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6611 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6612 errors in XSetWindowBorder (bug#9310).
6614 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6616 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6617 avoid crash when xmalloc overrun checking is enabled.
6619 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6621 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6622 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6623 cursor motion with <left> and <right> arrow keys.
6625 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6626 some callers set that themselves.
6628 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6630 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6631 display string and the previous row comes from the same string and
6632 is empty. (Bug#9739) (Bug#9738)
6634 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6636 * doc.c (get_doc_string): Encode file name (bug#9735).
6638 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6640 * bidi.c (bidi_level_of_next_char):
6641 * xdisp.c (get_visually_first_element): Remove old incorrect
6642 comments regarding the Unicode Line Separator character.
6644 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6646 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6648 * alloc.c (Fgc_status): Do not access beyond zombies array
6649 boundary if nzombies > MAX_ZOMBIES.
6650 * alloc.c (dump_zombies): Add missing format specifier.
6652 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6654 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6655 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6657 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6658 Some packages use them to denote characters with modifiers.
6660 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6662 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6663 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6664 matching a pp-number. Rename parameter var to var1.
6666 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6668 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6670 2011-10-08 Glenn Morris <rgm@gnu.org>
6672 * callint.c (Fcall_interactively): Give a more explicit error for the
6673 'c' case with a non-character input. (Bug#8479)
6675 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6677 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6679 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6680 lines that are hscrolled on the left.
6682 * dispnew.c (buffer_posn_from_coords): Account for a possible
6683 presence of header-line. (Bug#4426)
6685 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6687 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6688 Don't advertise functionality which we discourage or doesn't work.
6690 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6692 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6693 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6694 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6695 this makes Emacs dump core during garbage collection on rare
6696 occasions. sizeof is obviously inferior to offsetof here, so
6697 stick with offsetof.
6698 (GC_POINTER_ALIGNMENT): New macro.
6699 (mark_memory): Omit 3rd (offset) arg; caller changed.
6700 Don't assume EMACS_INT alignment is the same as pointer alignment.
6702 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6704 * keyboard.c (read_key_sequence_remapped): New var.
6705 (read_key_sequence): Compute remapping in the right buffer.
6706 (command_loop_1): Use read_key_sequence's remapping directly.
6708 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6710 * dired.c (file_name_completion): Don't expand file name.
6711 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6712 before checking file name handler.
6714 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6715 they've been requested explicitly (bug#9591).
6717 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6719 * keymap.c (Fsingle_key_description): Use make_specified_string
6720 instead of build_string to build string from push_key_description.
6723 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6725 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6726 This fixes a Y2038 bug on 64-bit hosts.
6727 * buffer.c (reset_buffer):
6728 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6729 (Fclear_buffer_auto_save_failure):
6730 Use 0, not -1, to represent an unset failure time, since time_t
6731 might not be signed.
6733 Remove dependency on glibc malloc internals.
6734 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6735 Move back here from lisp.h, but with their new implementations.
6736 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6737 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6738 * charset.c (charset_table_init): New static var.
6739 (syms_of_charset): Use it instead of xmalloc. This removes a
6740 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6741 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6742 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6743 Move back to alloc.c.
6744 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6745 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6747 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6749 * nsterm.m (windowDidResize): Call x_set_window_size only when
6750 ns_in_resize is true. Otherwise set pixelwidth/height and
6751 call change_frame_size (Bug#9628).
6753 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6755 Port --enable-checking=all to Fedora 14 x86-64.
6756 * charset.c (syms_of_charset): Also account for glibc malloc's
6757 internal overhead when calculating the initial malloc maximum.
6759 Port --enable-checking=all to Fedora 14 x86.
6760 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6762 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6763 (overrun_check_realloc, overrun_check_free):
6764 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6765 That way, xmalloc returns a properly-aligned pointer even if
6766 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6767 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6768 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6769 into account when calculating the initial malloc maximum.
6770 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6771 Move here from alloc.c, so that charset.c can use it too.
6772 Properly align; the old code wasn't right for common 32-bit hosts
6773 when configured with --enable-checking=all.
6774 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6775 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6777 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6779 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6782 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6784 * xdisp.c (compute_display_string_end): If there's no display
6785 string at CHARPOS, return -1.
6787 * bidi.c (bidi_fetch_char): When compute_display_string_end
6788 returns a negative value, treat the character as a normal
6789 character not covered by a display string. (Bug#9624)

6793 * lread.c (Fread_from_string): Fix typo in docstring.
6795 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6797 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6798 newline, reseat the iterator instead of bidi-iterating there one
6799 character at a time. (Bug#9610)
6800 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6801 TO_CHARPOS if the bidi iterator is at base embedding level.
6803 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6805 * lread.c (readevalloop): Use correct code for NBSP.
6806 (read1): Likewise. (Bug#9608)
6808 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6810 * dbusbind.c (Fdbus_register_signal): When service is not
6811 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6813 2011-09-25 Glenn Morris <rgm@gnu.org>
6815 * buffer.c (truncate-lines): Doc fix.
6817 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

6832 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6834 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6835 Default value is now t. Doc fix.
6837 * indent.c (Fvertical_motion): Compute and apply the overshoot
6838 logic when moving up, not only when moving down. Fix the
6839 confusing name and values of the it_overshoot_expected variable;
6840 logic changes accordingly. (Bug#9254) (Bug#9549)
6842 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6843 CHARPOS is covered by a display string which includes newlines.
6844 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6845 is covered by a display string with embedded newlines.
6847 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6849 * dbusbind.c (Fdbus_register_signal): Add match rule to
6850 Vdbus_registered_objects_table. (Bug#9581)
6851 (Fdbus_register_method, Vdbus_registered_objects_table):
6854 2011-09-24 Jim Meyering <meyering@redhat.com>
6856 do not ignore write error for any output size
6857 The previous change was incomplete.
6858 While it makes emacs --batch detect the vast majority of stdout
6859 write failures, errors were still ignored whenever the output size is
6860 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6861 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6862 && echo FAIL: ignored write error
6863 FAIL: ignored write error
6864 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6865 && echo FAIL: ignored write error
6866 FAIL: ignored write error
6867 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6869 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6871 * emacs.c (Fkill_emacs): In noninteractive mode exit
6872 non-successfully if a write error occurred on stdout. (Bug#9574)
6874 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6876 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6879 * dispextern.h (struct it): Update the comment documenting what
6882 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6884 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6885 a display string, extend search for cursor position to end of row.
6886 (find_row_edges): If the row ends in a newline from a display
6887 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6888 Handle the case of a display string with multiple newlines.
6889 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6890 non-empty line. Fixes confusing cursor motion with arrow keys at
6891 the beginning of a line that starts with whitespace.
6893 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6895 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6898 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6900 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6903 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6905 * xdisp.c (display_line): Record maximum and minimum buffer
6906 positions even if no glyphs were produced (e.g., by a zero-width
6907 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6908 buffer positions that will be removed from the glyph row because
6910 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6911 column is beyond frame width: don't subtract 1 "pixel" when
6912 computing width of the stretch.
6913 (reseat_at_next_visible_line_start): Undo the change made on
6914 2011-09-17 that saved paragraph information and restored it after
6915 the call to `reseat'. (Bug#9545)
6917 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6919 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6920 and turn window cursor on if cleared (Bug#9415).

6924 * search.c (boyer_moore): Take unibyte characters from pattern
6925 literally. (Bug#9458)
6927 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6929 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6931 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6933 Fix minor problem found by static checking.
6934 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6935 initialized, to pacify gcc -Wuninitialized.
6937 * fileio.c: Report proper errno when syscall falls.
6938 (Finsert_file_contents): Save and restore errno,
6939 so that report_file_error outputs the correct diagnostic.
6940 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6942 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6944 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6946 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6948 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6949 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6951 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6953 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6954 about the current paragraph and restore it after the call to reseat.
6956 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6957 (bidi_find_paragraph_start): Search back for paragraph beginning
6958 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6959 (bidi_move_to_visually_next): Only trigger paragraph-related
6960 computations when the last character is a newline or at EOB, not
6961 just any NEUTRAL_B. (Bug#9470)
6963 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6964 truncated lines if point is covered by a display string. (Bug#9524)
6966 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6968 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6969 (cons_to_x_long): New function.
6970 (lisp_data_to_selection_data): Use it. Correct the test for
6971 short-versus-long data; it was negated. Break out of vector
6972 loop, for efficiency, when a long datum is discovered.
6974 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6976 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6978 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6980 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6981 GCC PR/17406) by declaring this function with external scope.
6983 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6985 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6986 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6988 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6990 * editfns.c (Fformat): Correctly handle text properties on "%%".

7000 of TAB characters in a composition.
7002 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7004 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7005 This occurs when processing a multibyte format.
7006 Problem reported by Wolfgang Jenker.
7008 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7010 * xdisp.c (try_cursor_movement): Only check for exact match if
7011 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7013 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7015 Remove unused external symbols.
7016 * dispextern.h (calc_pixel_width_or_height): Remove decl.

7018 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7019 * indent.c (check_display_width):
7020 * w32term.c: Fix comment to match code.
7021 * xterm.c, xterm.h (x_catching_errors): Remove.
7023 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7025 * xselect.c: Use signed conversions more consistently (Bug#9498).
7026 (selection_data_to_lisp_data): Assume incoming selection data are
7027 signed integers, not unsigned. This is to be consistent with
7028 outgoing selection data, which was modified to use signed integers
7029 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7030 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7031 expects long, not unsigned long.
7033 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7035 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7036 computation of loop end. Reported by Johan Bockgård
7039 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7041 * frame.c (Fother_visible_frames_p): Function deleted.
7043 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7045 * indent.c (compute_motion): Process display vector front to back
7046 rather than the other way around. (Bug#2496)
7048 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7050 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7052 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7054 * minibuf.c (Fread_from_minibuffer): Doc fix.
7056 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7058 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7059 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7061 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7063 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7064 value for non-existent files.
7066 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7068 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7069 set its "size" to -1. This will set the modtime_size field of
7070 the corresponding buffer to -1, which is what
7071 verify-visited-file-modtime expects for files that do not exist.
7074 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7076 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7078 * lisp.h: ... from here. push_key_description is no longer
7079 defined in keyboard.c, so its declaration should not be in
7080 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7081 logically belongs with push_key_description.
7083 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7085 * buffer.h: Include <sys/types.h> instead of <time.h>.
7086 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7087 Problem reported by Herbert J. Skuhra.
7089 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7091 * xml.c (parse_region): Make the parsing work for
7092 non-comment-starting XML files again (bug#9144).
7094 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7096 * image.c (gif_load): Fix calculation of bottom and right corner.
7099 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7101 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7102 redisplay in small windows.
7104 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7106 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7108 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7110 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7111 Operate on live windows only.
7113 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7115 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7117 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7119 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7120 only under bidi iteration.
7122 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7124 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7126 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7128 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7129 Without this fix, the command to link temacs failed due to an
7130 undefined symbol __builtin_isnan. This is because
7131 /usr/include/iso/math_c99.h #defines isnan(x) to
7132 __builtin_isnan(x), but the bundled gcc, which identifies itself
7133 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7135 * floatfns.c (isnan): #undef, and then #define to a clone of
7137 (Fisnan): Always define, since it's always available now.
7138 (syms_of_floatfns): Always define isnan at the Lisp level.
7140 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7142 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7144 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7146 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7147 The previous code assumed that file offsets (off_t values) fit in
7148 EMACS_INT variables, which is not true on typical 32-bit hosts.
7149 The code messed up by falsely reporting buffer overflow in cases
7150 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7151 when "big" contains more than 2**29 bytes, even though this
7152 inserts just one byte and does not overflow the buffer.
7153 (Finsert_file_contents): Store file offsets as off_t
7154 values, not as EMACS_INT values. Check for overflow when
7155 converting between EMACS_INT and off_t. When checking for
7156 buffer overflow or for overlap, take the offsets into account.
7157 Don't use EMACS_INT for small values where int suffices.
7158 When checking for overlap, fix a typo: ZV was used where
7159 ZV_BYTE was intended.
7160 (Fwrite_region): Don't assume off_t fits into 'long'.
7161 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7163 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7165 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7167 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7169 sprintf-related integer and memory overflow issues (Bug#9412).
7171 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7172 (esprintf, exprintf, evxprintf): New functions.
7173 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7174 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7175 (modify_event_symbol): Do not assume that the length of
7176 name_alist_or_stem is safe to alloca and fits in int.
7177 (Fexecute_extended_command): Likewise for function name and binding.
7178 (Frecursion_depth): Wrap around reliably on integer overflow.
7179 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7180 since some callers pass EMACS_INT values.
7181 (Fsingle_key_description): Don't crash if symbol name contains more
7182 than MAX_ALLOCA bytes.
7183 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7184 (get_minibuffer): Arg is now EMACS_INT, not int.
7185 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7186 (esprintf, exprintf, evxprintf): New decls.
7187 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7189 * dbusbind.c (signature_cat): New function.
7190 (xd_signature, Fdbus_register_signal):
7191 Do not overrun buffer; instead, report string overflow.
7193 * dispnew.c (add_window_display_history): Don't overrun buffer.
7194 Truncate instead; this is OK since it's just a log.
7196 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7197 even if the time zone offset is outlandishly large.
7198 Don't mishandle offset == INT_MIN.
7200 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7201 when creating daemon; the previous buffer-overflow check was incorrect.
7203 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7204 which has the guts of the old verror function.
7206 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7207 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7209 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7210 (font_unparse_xlfd): Don't blindly alloca long strings.
7211 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7212 fits in int, when using sprintf. Use single snprintf to count
7213 length of string rather than counting it via multiple sprintfs;
7214 that's simpler and more reliable.
7215 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7216 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7217 sprintf, in case result does not fit in int.
7219 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7220 (fontset_from_font): Print it.
7222 * frame.c (tty_frame_count): Now printmax_t, not int.
7223 (make_terminal_frame, set_term_frame_name): Print it.
7224 (x_report_frame_params): In X, window IDs are unsigned long,
7225 not signed long, so print them as unsigned.
7226 (validate_x_resource_name): Check for implausibly long names,
7227 and don't assume name length fits in 'int'.
7228 (x_get_resource_string): Don't blindly alloca invocation name;
7229 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7232 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7233 (xg_check_special_colors, xg_set_geometry):
7234 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7236 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7237 Use esprintf, not sprintf, in case result does not fit in int.
7239 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7240 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7241 it as a large positive number.
7242 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7243 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7245 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7246 in case result does not fit in int.
7248 * print.c (float_to_string): Detect width overflow more reliably.
7249 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7250 buffer overrun. Don't assume list length fits in 'int'. Treat
7251 print length of 0 as 0, not as infinity; to be consistent with other
7252 uses of print length in this function. Don't overflow print length
7253 index. Don't assume hash table size fits in 'long', or that
7254 vectorlike size fits in 'unsigned long'.
7256 * process.c (make_process): Use printmax_t, not int, to format
7257 process-name gensyms.
7259 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7261 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7262 to avoid potential buffer overrun.
7264 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7265 if X resource line is longer than 512 bytes.
7267 * xfns.c (x_window): Make sprintf buffer a bit bigger
7268 to avoid potential buffer overrun.
7270 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7272 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7274 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7276 Integer overflow fixes for scrolling, etc.
7277 Without these, Emacs silently mishandles large integers sometimes.
7278 For example, "C-u 4294967297 M-x recenter" was treated as if
7279 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7281 * xdisp.c (try_window_id): Check Emacs fixnum range before
7282 converting to 'int'.
7284 * window.c (window_scroll_line_based, Frecenter):
7285 Check that an Emacs fixnum is in range before assigning it to 'int'.
7286 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7287 values converted from Emacs fixnums.
7288 (Frecenter): Don't wrap around a line count if it is out of 'int'
7289 range; instead, treat it as an extreme value.
7290 (Fset_window_configuration, compare_window_configurations):
7291 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7293 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7294 that can exceed INT_MAX. Check that EMACS_INT value is in range
7295 before assigning it to the (possibly-narrower) index.
7296 (match_limit): Don't assume that a fixnum can fit in 'int'.
7298 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7301 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7302 (Fvertical_motion): Don't wrap around LINES values that don't fit
7303 in 'int'. Instead, treat them as extreme values. This is good
7304 enough for windows, which can't have more than INT_MAX lines anyway.
7306 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7308 * Require libxml/parser.h to avoid compilation warning.
7310 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7312 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7313 since this reportedly can destroy thread storage.
7315 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7317 * syntax.c (find_defun_start): Update all cache variables if
7318 exiting early (Bug#9401).
7320 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7322 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7324 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7325 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7326 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7328 * term.c (tty_append_glyph): New function.
7329 (produce_stretch_glyph): Static function and its prototype deleted.
7331 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7334 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7336 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7337 when checking :margin (Bug#9390).
7338 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7339 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7340 so that the name doesn't mislead. All uses changed.
7342 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7344 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7347 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7349 * xdisp.c (move_it_to): Don't bail out early when reaching
7350 position beyond to_charpos, if we are scanning backwards.
7351 (move_it_vertically_backward): When DY == 0, make sure we get to
7352 the first character in the line after the newline.
7354 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7356 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7357 (ccl_driver): Do not generate an out-of-range pointer.
7358 (Fccl_execute_on_string): Remove unnecessary check for
7359 integer overflow, noted by Stefan Monnier in
7360 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7361 Remove a FIXME that didn't need fixing.
7362 Simplify the newly-introduced buffer reallocation code.
7364 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7366 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7368 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7370 Integer and memory overflow issues (Bug#9196).
7372 * doc.c (get_doc_string): Rework so that
7373 get_doc_string_buffer_size is the actual buffer size, rather than
7374 being 1 less than the actual buffer size; this makes xpalloc more
7377 * image.c (x_allocate_bitmap_record, cache_image):
7378 * xselect.c (Fx_register_dnd_atom):
7379 Simplify previous changes by using xpalloc.
7381 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7382 since either will do and ptrdiff_t is convenient with xpalloc.
7384 * charset.c (charset_table_size)
7385 (struct charset_sort_data.priority): Now ptrdiff_t.
7386 (charset_compare): Don't overflow if priorities differ greatly.
7387 (Fsort_charsets): Don't assume list length fits in int.
7388 Check for size-calculation overflow when allocating sort data.
7389 (syms_of_charset): Allocate an initial charset table that is
7390 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7392 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7394 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7395 The actual value is always <= INT_MAX, and leaving it unsigned made
7396 overflow checking harder.
7398 * dispextern.h (struct glyph_matrix.rows_allocated)
7399 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7400 with xpalloc. The values are still always <= INT_MAX.
7402 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7404 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7405 (SAFE_NALLOCA): New macro.
7407 * region-cache.c (struct boundary.pos, find_cache_boundary)
7408 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7409 (set_cache_region, invalidate_region_cache)
7410 (revalidate_region_cache, know_region_cache, region_cache_forward)
7411 (region_cache_backward, pp_cache):
7412 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7413 so that ptrdiff_t * can be passed to xpalloc.
7414 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7415 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7416 (pp_cache): Don't assume cache_len fits in int.
7417 * region-cache.h: Adjust extern decls to match.
7419 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7420 EMACS_INT, since either will do, for xpalloc.
7422 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7423 (xnmalloc, xnrealloc, xpalloc): New functions.
7425 * bidi.c (bidi_shelve_header_size): New constant.
7426 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7427 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7429 * bidi.c (bidi_cache_shrink):
7430 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7432 Don't update size of array until after memory allocation succeeds,
7433 because xmalloc/xrealloc may not return.
7434 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7435 now that we have proper integer overflow checking.
7436 (record_overlay_string, overlay_strings): Catch overflows when
7437 calculating size of overlay_str_buf.
7439 * callproc.c (Fcall_process): Check for size overflow when
7440 calculating size of args2.
7441 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7442 Normally we prefer signed values, but sticking with ptrdiff_t would
7443 require adding more-complicated checks.
7445 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7446 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7447 Redo buffer-overflow calculations to avoid integer overflow.
7448 Add a FIXME comment where memory seems to be over-allocated.
7450 * character.c (Fstring): Check for size-calculation overflow.
7452 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7453 unnecessary integer overflow. Check for size overflow.
7454 (encode_coding_object): Don't update size until xmalloc succeeds.
7456 * composite.c (get_composition_id): Check for overflow in glyph
7457 length calculations.
7459 Integer and memory overflow fixes for display code.
7460 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7461 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7462 (scrolling_window): Check for overflow in size calculations.
7463 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7475 (get_doc_string): Check for size calculation overflow.
7476 Don't update size until allocation succeeds.
7477 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7478 EMACS_INT, where ptrdiff_t will do.
7479 (Fsubstitute_command_keys): Check for string overflow.
7481 * editfns.c (set_time_zone_rule): Don't assume environment length
7483 (message_length): Now ptrdiff_t, not int.
7484 (Fmessage_box): Don't update size until allocation succeeds.
7485 Don't assume message length fits in int.
7486 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7488 * emacs.c (main): Do not reallocate argv, since there is a null at
7489 the end that can be overwritten, and this way there's no need to
7490 worry about size-calculation overflow.
7491 (sort_args): Check for size-calculation overflow.
7493 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7495 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7497 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7498 (x_set_scroll_bar_width, x_figure_window_size):
7499 Check for integer overflow.
7500 (x_set_alpha): Do not assume XINT fits in int.
7502 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7503 This is for the members text_lines, text_cols, total_lines, total_cols,
7504 where the system imposes an 'int' limit.
7506 * fringe.c (Fdefine_fringe_bitmap):
7507 Don't update size until alloc works.
7509 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7510 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7512 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7513 Check for size-calculation overflow.
7514 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7515 do, as we prefer signed integers.
7516 (id_to_widget.max_size, id_to_widget.used)
7517 (xg_store_widget_in_map, xg_remove_widget_from_map)
7518 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7519 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7520 Use and return ptrdiff_t, not int.
7521 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7522 * gtkutil.h: Change prototypes to match the above.
7524 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7525 are duplicate now that they've been promoted to lisp.h.
7526 (x_allocate_bitmap_record, x_alloc_image_color)
7527 (make_image_cache, cache_image, xpm_load):
7528 Don't update size until alloc is done.

7538 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7539 Use ptrdiff_t, not int, to count maps.
7540 (read_char_minibuf_menu_prompt): Check for overflow in size
7541 calculations. Don't update size until allocation succeeds.

7568 * search.c (Freplace_match): Check for size calculation overflow.
7569 (Fset_match_data): Don't assume list lengths fit in 'int'.
7571 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7572 for command line length. Do not attempt to address one before the
7573 beginning of an array, as that's not portable.

7576 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7578 (encode_terminal_code, calculate_costs): Check for size
7579 calculation overflow.

7581 table lengths and related sizes. Don't update size until alloc
7582 done. Redo calculations to avoid overflow.
7583 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7585 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7601 Use ptrdiff_t, not int, for sizes.
7602 (Finternal_make_lisp_face, cache_face):
7603 Check for size calculation overflow.
7604 (cache_face): Treat size calculation overflows as if they were
7605 memory exhaustion (the usual treatment), rather than aborting.
7607 * xfns.c (x_encode_text, x_set_name_internal)
7608 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7609 sizes, since they can exceed INT_MAX in size. Check for size
7610 calculation overflow.

7613 (xg_select): Check for size calculation overflow.
7614 Don't update size until alloc done.
7616 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7617 as sprintf is limited to int lengths.
7619 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7620 (X_LONG_MIN): New macros.
7621 Use them to make the following changes clearer.
7622 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7623 This change doesn't affect the value now, but it may help remind
7624 future maintainers not to raise the value too much later.
7625 (SELECTION_QUANTUM): Remove, replacing with ...
7626 (selection_quantum): ... new function, which avoids overflow.
7628 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7629 assumption that selection length fits in 'int'.
7630 (x_reply_selection_request, x_handle_selection_request)

7637 Redo calculations to avoid overflow.
7638 (x_reply_selection_request): When sending hint, ceiling it at
7639 X_LONG_MAX rather than relying on wraparound overflow to send

7642 (lisp_data_to_selection_data, x_property_data_to_lisp):
7643 Check for size-calculation overflow.

7646 Don't store size until memory allocation succeeds.
7647 (x_get_window_property): Plug memory leak on memory exhaustion.
7648 Don't double-block input; malloc is safe here. Don't assume 2**34
7649 - 4 fits in unsigned long. Add an xassert to check
7650 XGetWindowProperty overflow. Be more careful about overflow
7651 calculations, and distinguish size from memory overflow better.
7652 (receive_incremental_selection): When tracing, don't assume
7653 unsigned int is less than INT_MAX.
7654 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7655 harmful) conversions of unsigned short to int.
7656 (lisp_data_to_selection_data): Don't assume that integers
7657 in the range -65535 through -1 fit in an X unsigned short.
7658 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7659 result parameters unless successful. Rely on cons_to_unsigned
7660 to report problems with elements; the old code wasn't right anyway.
7661 (x_check_property_data): Check for int overflow; we cannot use
7662 a wider type due to X limits.
7663 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7694 * image.c (xpm_get_color_table_h):
7695 * lisp.h (hash_lookup, hash_put):
7696 * minibuf.c (Ftest_completion):
7697 Use ptrdiff_t for hash table indexes, not int (which is too
7698 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7699 32-bit --with-wide-int hosts).
7701 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7702 Add a FIXME comment about memory leaks.

7707 * character.h (CHAR_WIDTH):
7708 * indent.c (MULTIBYTE_BYTES_WIDTH):
7709 Use sanitize_char_width to avoid undefined and/or bad behavior
7710 with outlandish widths.
7711 * character.h (sanitize_tab_width): Rename from sanitize_width,
7712 now that we have two such functions. All uses changed.
7713 (sanitize_char_width): New inline function.
7715 Don't assume that tab-width fits in int.
7716 * character.h (sanitize_width): New inline function.
7717 (SANE_TAB_WIDTH): New macro.

7730 * xterm.c: Don't go over XClientMessageEvent limit.
7731 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7732 (x_send_scroll_bar_event): Likewise. Check that the size does not
7733 exceed limits imposed by XClientMessageEvent, as well as the usual
7734 ptrdiff_t and size_t limits.
7736 * keyboard.c: Overflow, signedness and related fixes.
7737 (make_lispy_movement): Use same integer type in forward decl
7738 that is used in the definition.
7739 (read_key_sequence, keyremap_step):
7740 Change bufsize argument back to int, undoing my 2011-03-30 change.
7741 We prefer signed types, and int is wide enough here.
7742 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7743 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7744 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7745 length, not size_t. Use ptrdiff_t for index, not int.
7746 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7747 possibility of integer overflow.
7749 Overflow, signedness and related fixes for images.
7751 * dispextern.h (struct it.stack[0].u.image.image_id)
7752 (struct_it.image_id, struct image.id, struct image_cache.size)

7758 * nsmenu.m (update_frame_tool_bar):
7759 * xdisp.c (calc_pixel_width_or_height):
7760 * xfns.c (image_cache_refcount):

7768 when the callers expect that.
7769 (image_ascent): Redo ascent calculation to avoid int overflow.
7770 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7771 (lookup_image): Remove unnecessary tests.
7772 (xbm_image_p): Locals are now of int, not EMACS_INT,
7773 since parse_image_check makes sure they fit into int.
7774 (png_load, gif_load, svg_load_image):
7775 Prefer int to unsigned where either will do.
7776 (tiff_handler): New function, combining the cores of the
7777 old tiff_error_handler and tiff_warning_handler.
7778 This function is rewritten to use vsnprintf and thereby avoid
7779 stack buffer overflows. It uses only the features of vsnprintf
7780 that are common to both POSIX and native Microsoft.
7781 (tiff_error_handler, tiff_warning_handler): Use it.
7782 (tiff_load, gif_load, imagemagick_load_image):
7783 Don't assume :index value fits in 'int'.
7784 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7785 (imagemagick_load_image): Check that crop parameters fit into
7786 the integer types that MagickCropImage accepts. Don't assume
7787 Vimagemagick_render_type has a nonnegative value. Don't assume
7788 size_t fits in 'long'.
7789 (gs_load): Use printmax_t to print the widest integers possible.
7790 Check for integer overflow when computing image height and width.
7792 2011-08-26 Eli Zaretskii <eliz@gnu.org>

7802 handle_single_display_spec, not just 1 or zero.
7803 (handle_single_display_spec): If the display spec is of the form
7804 `(space ...)', and specifies display in the text area, return 2
7806 (try_cursor_movement): Check for the need to scroll more
7807 accurately, and prefer exact match for point under bidi.
7808 Don't advance `row' beyond the last row of the window.
7810 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7811 into disp_prop; all users changed.
7813 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7814 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7815 for the text covered by the display property.
7817 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7819 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7825 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7826 buffers, return left-to-right.
7827 (set_cursor_from_row): Consider candidate row a win if its glyph
7828 represents a newline and point is on that newline. Fixes cursor
7829 positioning on the newline at EOL of R2L text within L2R
7830 paragraph, and vice versa.
7831 (try_cursor_movement): Check continued rows, in addition to
7832 continuation rows. Fixes unwarranted scroll when point enters a
7833 continued line of R2L text within an L2R paragraph, or vice versa.
7834 (cursor_row_p): Consider the case of point being equal to
7835 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7836 from the end of a short line to the beginning of a continued line
7837 of R2L text within L2R paragraph.
7838 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7839 composed characters.
7841 * bidi.c (bidi_check_type): Use xassert.
7842 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7845 2011-08-23 Eli Zaretskii <eliz@gnu.org>

7850 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7852 * nsfont.m (ns_otf_to_script): Fix typo.
7854 2011-08-22 Kenichi Handa <handa@m17n.org>
7856 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7857 extra slot even if the purpose is char-code-property-table.
7859 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7861 * xdisp.c (redisplay_window): When computing centering_position,
7862 account for the height of the header line. (Bug#8874)
7864 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7865 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7866 candidate is selected by the mouse, and that candidate has a
7867 composed character under the mouse.
7869 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7870 coordinates reported by pos-visible-in-window-p for a composed
7871 character in column zero.

7875 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7877 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7879 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7880 consider it a hit if to_charpos is anywhere in the range of the
7881 composed buffer positions.
7883 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7885 * image.c (gif_load): Don't assume that each subimage has the same
7886 dimensions as the base image. Handle disposal method that is
7887 "undefined" by the gif spec (Bug#9335).
7889 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7891 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7892 (Fcondition_case): Document `debug' symbol in error handler.
7894 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7896 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7897 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7898 from an Org mode buffer to a Speedbar frame.
7900 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7901 a composition, take its buffer position from IT->cmp_it.charpos.
7902 Fixes cursor positioning at the beginning of a line that begins
7903 with a composed character.
7905 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7907 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7908 character bidirectional type, use STRONG_L instead. Fixes crashes
7909 in a buffer produced by `describe-categories'.
7911 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7912 members before the level stack, so they would be saved and
7913 restored when copying iterator state. Fixes incorrect reordering
7914 around TABs covered by display properties.
7916 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7918 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8002 the event loop. Get status from as_status (Bug#7276).
8004 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8005 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8006 the event loop (Bug#7276).

8032 (Fnetwork_interface_list): Allocate in increments of bytes instead
8033 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8034 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

8037 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8038 Get hardware address with getifaddrs if available.
8040 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8042 * xdisp.c (iterate_out_of_display_property): xassert that
8043 IT->position is set to within IT->object's boundaries. Break from
8044 the loop as soon as EOB is reached; avoids infloops in redisplay

8046 Set IT->current to match the bidi iterator unconditionally.
8047 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8048 entry. Force push_it to save on the stack the current
8049 buffer/string position, to be restored by pop_it. Fix flags in
8050 the iterator structure wrt the object coming from a display
8051 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8052 properties. (Bug#9284)
8054 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8056 * fontset.c (fontset_get_font_group): Add proper type checks.

8097 word-wrap under bidirectional display. (Bug#9224)
8099 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8100 is non-zero, even if the data buffer is NULL. Fixes a crash in
8101 vertical-motion with longlines-mode. (Bug#9254)
8103 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8105 * bidi.c <bidi_cache_total_alloc>: Now static.

8111 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8112 amount allocated this far in `bidi_cache_total_alloc'.
8113 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if

8210 * regex.c (re_comp): Protoize.
8211 (re_exec): Fix return type.
8212 (regexec): Fix type of `ret'. (Bug#9203)
8214 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8216 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8217 This is needed if max-image-size is a floating-point number.
8219 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8221 * print.c (print_object): Print empty symbol as ##.
8223 * lread.c (read1): Read ## as empty symbol.
8225 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8227 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8228 setting frame foreground color (Bug#9175).
8229 (x_set_background_color): Likewise.
8231 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8232 contents (Bug#9176).
8233 (EmacsTooltip -init): Remove bezels and add shadows to
8236 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8237 or scroll bar (Bug#8470).
8239 * nsfont.m (nsfont_open): Remove assignment to voffset and
8240 unnecessary vars hshink, expand, hd, full_height, min_height.
8241 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8243 * nsterm.h (nsfont_info): Remove voffset field.
8245 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8247 Implement strike-through and overline on NextStep (Bug#8863).
8249 * nsfont.m (nsfont_open): Use underline position provided by font,
8250 instead of hard-coded value of 2.
8251 (nsfont_draw): Call ns_draw_text_decoration instead.
8253 * nsterm.h: Add declaration for ns_draw_text_decoration.
8255 * nsterm.m (ns_draw_text_decoration): New function for drawing
8256 underline, overline, and strike-through.
8257 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8258 ns_draw_text_decoration. Change treatment of cursor drawing to
8259 accommodate underlining, etc.
8261 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8263 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8266 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8268 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8269 Without this fix, if a signal arrives just after memory fills up,
8270 'malloc' might be invoked reentrantly.
8272 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8273 In other words, assume that every image size is allowed, on non-X
8274 hosts. This assumption is probably wrong, but it lets Emacs compile.
8276 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8278 * regex.c (re_iswctype): Convert return values to boolean.
8280 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8282 * xdisp.c (compute_display_string_pos): Don't use cached display
8283 string position if the buffer had its restriction changed.
8286 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8288 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8290 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8292 Integer signedness and overflow and related fixes. (Bug#9079)
8294 * bidi.c: Integer size and overflow fixes.
8295 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8296 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8297 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8298 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8299 (bidi_find_other_level_edge):
8300 Use ptrdiff_t instead of EMACS_INT where either will do.
8301 This works better on 32-bit hosts configured --with-wide-int.
8302 (bidi_cache_ensure_space): Check for size-calculation overflow.
8303 Use % rather than repeated addition, for better worst-case speed.
8304 Don't set bidi_cache_size until after xrealloc returns, because it
8306 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8307 (bidi_cache_ensure_space): Also check that the bidi cache size
8308 does not exceed that of the largest Lisp string or buffer. See Eli
8309 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8311 * alloc.c (__malloc_size_t): Remove.
8312 All uses replaced by size_t. See Andreas Schwab's note
8313 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8315 * image.c: Improve checking for integer overflow.
8316 (check_image_size): Assume that f is nonnull, since
8317 it is always nonnull in practice. This is one less thing to
8318 worry about when checking for integer overflow later.
8319 (x_check_image_size): New function, which checks for integer
8320 overflow issues inside X.
8321 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8322 This removes the need for a memory_full check.
8323 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8324 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8325 (xbm_read_bitmap_data): Change locals back to 'int', since
8326 their values must fit in 'int'.
8327 (xpm_load_image, png_load, tiff_load):
8328 Invoke x_create_x_image_and_pixmap earlier,
8329 to avoid much needless work if the image is too large.
8330 (tiff_load): Treat overly large images as if
8331 x_create_x_image_and_pixmap failed, not as malloc failures.
8332 (gs_load): Use x_check_image_size.
8334 * gtkutil.c: Omit integer casts.
8335 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8336 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8338 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8340 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8341 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8342 would wrongly return t on a 64-bit host.
8344 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8345 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8346 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8347 and therefore cause GCC to emit a bogus diagnostic in some cases.
8349 * image.c: Integer signedness and overflow and related fixes.
8350 This is not an exhaustive set of fixes, but it's time to
8351 record what I've got.
8352 (lookup_pixel_color, check_image_size): Remove redundant decls.
8353 (check_image_size): Don't assume that arbitrary EMACS_INT values
8354 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8355 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8356 (tiff_load, imagemagick_load_image):
8357 Check for overflow in size calculations.
8358 (x_create_x_image_and_pixmap): Remove unnecessary test for
8359 xmalloc returning NULL; that can't happen.
8360 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8361 (xpm_color_bucket): Use better integer hashing function.
8362 (xpm_cache_color): Don't possibly over-allocate memory.
8363 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8364 (gif_memory_source):
8365 Use ptrdiff_t, not int or size_t, to record sizes.
8366 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8367 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8368 either works, as we prefer signed integers.
8369 (tiff_read_from_memory, tiff_write_from_memory):
8370 Return tsize_t, not size_t, since that's what the TIFF API wants.
8371 (tiff_read_from_memory): Don't fail simply because the read would
8372 go past EOF; instead, return a short read.
8373 (tiff_load): Omit no-longer-needed casts.
8374 (Fimagemagick_types): Don't assume size fits into 'int'.
8376 Improve hashing quality when configured --with-wide-int.
8377 * fns.c (hash_string): New function, taken from sxhash_string.
8378 Do not discard information about ASCII character case; this
8379 discarding is no longer needed.
8380 (sxhash-string): Use it. Change sig to match it. Caller changed.
8381 * lisp.h: Declare it.
8382 * lread.c (hash_string): Remove, since we now use fns.c's version.
8383 The fns.c version returns a wider integer if --with-wide-int is
8384 specified, so this should help the quality of the hashing a bit.
8386 * emacs.c: Integer overflow minor fix.
8387 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8388 Define only if GNU_LINUX.
8389 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8391 * dispnew.c: Integer signedness and overflow fixes.
8392 Remove unnecessary forward decls, that were a maintenance hassle.
8393 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8395 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8396 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8397 (prepare_desired_row, line_draw_cost):
8398 Use int, not unsigned, where either works.
8399 (save_current_matrix, restore_current_matrix):
8400 Use ptrdiff_t, not size_t, where either works.
8401 (init_display): Check for overflow more accurately, and without
8402 relying on undefined behavior.
8404 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8405 Remove, replacing with the new symbols in lisp.h. All uses changed.
8406 * fileio.c (make_temp_name):
8407 * filelock.c (lock_file_1, lock_file):
8408 * xdisp.c (message_dolog):
8409 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8410 Use pMd etc. instead.
8411 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8412 replacing the pWIDE etc. symbols removed from editfns.c.
8414 * keyboard.h (num_input_events): Now uintmax_t.
8415 This is (very slightly) less likely to mess up due to wraparound.
8418 * buffer.c: Integer signedness fixes.
8419 (alloc_buffer_text, enlarge_buffer_text):
8420 Use ptrdiff_t rather than size_t when either will do, as we prefer
8423 * alloc.c: Integer signedness and overflow fixes.
8424 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8425 (__malloc_size_t): Default to size_t, not to int.
8426 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8427 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8428 Prefer ptrdiff_t to size_t when either would do, as we prefer
8430 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8431 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8432 Now const. Initialize with values that are in range even if char
8434 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8435 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8436 These functions do the right thing with sizes > 2**32.
8437 (check_depth): Now ptrdiff_t, not int.
8438 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8439 Adjust to new way of storing sizes. Check for size overflow bugs
8441 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8442 slightly wrong anyway, as it missed one instance of
8443 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8444 (refill_memory_reserve): Omit needless cast to size_t.
8445 (mark_object_loop_halt): Mark as externally visible.
8447 * xselect.c: Integer signedness and overflow fixes.
8448 (Fx_register_dnd_atom, x_handle_dnd_message):
8449 Use ptrdiff_t, not size_t, since we prefer signed.
8450 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8451 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8452 x_dnd_atoms_size and x_dnd_atoms_length.
8454 * doprnt.c: Prefer signed to unsigned when either works.
8456 * doprnt.c (doprnt):
8458 * xdisp.c (vmessage):
8459 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8460 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8461 prefer signed arithmetic to avoid comparison confusion.
8462 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8463 but is a bit tricky.
8465 Assume freestanding C89 headers, string.h, stdlib.h.
8466 * data.c, doprnt.c, floatfns.c, print.c:
8467 Include float.h unconditionally.
8468 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8469 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8470 * regex.c: Likewise for stddef.h, string.h.
8471 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8472 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8473 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8474 (STDC_HEADERS): Remove obsolete defines.
8475 * sysdep.c: Include limits.h unconditionally.
8477 Assume support for memcmp, memcpy, memmove, memset.
8478 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8479 * regex.c (memcmp, memcpy):
8480 Remove; we assume C89 now.
8482 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8483 (__malloc_safe_bcopy): Remove; no longer needed.
8485 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8486 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8487 well either way, and we prefer signed to unsigned.
8489 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8491 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8492 closes the connection while we're reading (bug#9182).
8494 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8496 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8497 are specified (Bug#9168).
8499 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8501 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8502 Found by GCC static checking and --with-wide-int on a 32-bit host.
8504 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8506 * xdisp.c (compute_display_string_pos): Fix logic of caching
8507 previous display string position. Initialize cached_prev_pos to
8508 -1. Fixes slow-down at the beginning of a buffer.
8510 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8512 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8513 for attrs[LFACE_FONTSET_INDEX].
8515 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8517 * xml.c (parse_region): Remove unused local
8518 that was recently introduced.
8520 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8522 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8523 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8525 * xdisp.c (move_it_in_display_line_to): Record the best matching
8526 position for TO_CHARPOS while scanning the line, and restore it on
8527 exit if none of the characters scanned was an exact match.
8528 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8529 when exact match is impossible due to invisible text, and the
8530 lines are truncated.
8532 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8534 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8537 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8539 Fix a significant slow-down of cursor motion with C-n, C-p,
8540 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8541 auto-repeat under bidi redisplay in fontified buffers.
8542 * xdisp.c (compute_stop_pos_backwards): New function.
8543 (next_element_from_buffer): Call compute_stop_pos_backwards to
8544 find a suitable prev_stop when we find ourselves before
8546 (reseat): Don't look for prev_stop, as that could mean a very long
8548 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8549 <cached_disp_overlay_modiff>: Cache for last found display string
8551 (compute_display_string_pos): Return the cached position if asked
8552 about the same buffer in the same area of character positions, and
8553 the buffer wasn't changed since the time the display string
8554 position was cached.
8556 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8558 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8559 is an integer, which is important for empty lines. (Bug#9149)
8561 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8563 * frame.c (Fmodify_frame_parameters): In tty case, update the
8564 default face if necessary (Bug#4238).
8566 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8568 * editfns.c (Fstring_to_char): No need to explain what a character
8569 is in the docstring (Bug#6576).
8571 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8573 * xml.c (parse_region): Make sure we always return a tree.
8575 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8577 * xml.c (parse_region): If a document contains only comments,
8580 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8582 * xml.c (make_dom): Return comments, too.
8584 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8587 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8588 and the surrounding thread.
8589 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8590 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8591 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8593 * s/openbsd.h (BROKEN_SIGIO): Define.
8594 * unexelf.c (unexec) [__OpenBSD__]:
8595 Don't update the .mdebug section of the Alpha COFF symbol table.
8597 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8599 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8602 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8604 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8605 This fixes some race conditions on the permissions of any newly
8608 * alloc.c (valid_pointer_p): Use pipe, not open.
8609 This fixes some permissions issues when debugging.
8611 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8612 If fchown fails to set both uid and gid, try to set just gid,
8613 as that is sometimes allowed. Adjust the file's mode to eliminate
8614 setuid or setgid bits that are inappropriate if fchown fails.
8616 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8618 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8619 to compare Lisp_Objects.
8620 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8621 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8622 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8624 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8626 * lread.c (read_integer): Unread even EOF character.
8627 (read1): Likewise. Properly record start position of symbol.
8629 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8630 symbol character follows.
8632 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8634 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8635 This works around a problem with the previous change to Fcopy_file.
8636 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8637 and without this change, GCC might complain about discarding
8638 fchown's return value.
8640 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8642 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8644 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8646 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8648 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8650 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8651 it's used from the C level.
8653 * process.c: Use the same condition for POLL_FOR_INPUT in both
8654 keyboard.c and process.c (bug#1858).
8656 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8658 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8659 (Fgnutls_boot): Use it.
8661 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8663 * doc.c (Fsubstitute_command_keys): Revert last change.
8665 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8667 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8668 quotes the next character, and doesn't affect other longer
8669 sequences (bug#8935).
8671 * lread.c (syms_of_lread): Clarify that is isn't only

8736 the iterator is before prev_stop.
8737 (init_iterator): Initialize bidi_p from the default value of

9214 (clone_per_buffer_values): Don't assume that

9255 Random fixes. E.g., (random) never returned negative values.
9256 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9257 subseconds part to the entropy, as that's a bit more random.
9258 Prefer signed to unsigned, since the signedness doesn't matter and
9259 in general we prefer signed. When given a limit, use a
9260 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9261 latter isn't right if USE_2_TAGS_FOR_INTS.
9262 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9263 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9275 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9276 This is more efficient than Ffile_directory_p and avoids a minor race.
9278 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9280 * buffer.c (Foverlay_put): Say what the return value is
9283 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9284 is a directory before asking whether to use the file name
9286 (barf_or_query_if_file_exists): Make the "File is a directory"
9287 error be more correct.
9289 * fns.c (Frequire): Remove the mention of the .gz files, since
9290 that's installation-specific, but keep the mention of
9291 `get-load-suffixes'.
9293 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9295 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9306 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9307 Also (re)move comments that are misplaced or no longer relevant.

9408 * eval.c (struct backtrace): Simplify and port the data structure.
9409 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9410 signed bit field, as this assumption is not portable and it makes
9411 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9412 "char debug_on_exit : 1" as this is not portable either; instead,
9413 use the portable "unsigned int debug_on_exit : 1". Remove unused
9414 member evalargs. Remove obsolete comments about cc bombing out.
9416 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9578 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9580 Integer and buffer overflow fixes (Bug#8873).
9582 * print.c (printchar, strout): Check for string overflow.
9583 (PRINTPREPARE, printchar, strout):
9584 Don't set size unless allocation succeeds.

9590 * macros.c: Integer and buffer overflow fixes.
9591 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9592 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
9593 Use ptrdiff_t, not int, for sizes.
9594 Don't increment bufsize until after realloc succeeds.
9595 Check for size-calculation overflow.
9596 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
9598 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9600 * lread.c: Integer overflow fixes.
9601 (read_integer): Radix is now EMACS_INT, not int,
9602 to improve quality of diagnostics for out-of-range radices.
9603 Calculate buffer size correctly for out-of-range radices.
9604 (read1): Check for integer overflow in radices, and in
9605 read-circle numbers.
9606 (read_escape): Avoid int overflow.
9607 (Fload, openp, read_buffer_size, read1)
9608 (substitute_object_recurse, read_vector, read_list, map_obarray):
9609 Use ptrdiff_t, not int, for sizes.
9610 (read1): Use EMACS_INT, not int, for sizes.
9611 Check for size overflow.
9613 * image.c (cache_image): Check for size arithmetic overflow.
9615 * lread.c: Integer overflow issues.
9616 (saved_doc_string_size, saved_doc_string_length)
9617 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9618 Now ptrdiff_t, not int.
9619 (read1): Don't assume doc string length fits in int. Check for
9620 out-of-range doc string lengths.
9621 (read_list): Don't assume file position fits in int.
9622 (read_escape): Check for hex character overflow.
9624 2011-06-22 Leo Liu <sdl.web@gmail.com>
9626 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9627 Move to minibuffer.el.
9629 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9631 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9632 The following patches are for when GLYPH_DEBUG && !XASSERT.
9633 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9634 * dispnew.c (flush_stdout):
9635 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9636 Mark as externally visible.
9637 * dispnew.c (check_window_matrix_pointers): Now static.
9638 * dispnew.c (window_to_frame_vpos):
9639 * xfns.c (unwind_create_frame):
9640 * xterm.c (x_check_font): Remove unused local.
9641 * scroll.c (CHECK_BOUNDS):
9642 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9643 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9644 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9645 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9646 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9648 (debug_method_add): Use va_list and vsprintf rather than relying
9649 on undefined behavior with wrong number of arguments.
9650 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9651 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9652 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9653 since we're not interested in debugging glyphs with old libraries.
9654 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9655 GCC 4.6.0's static checking.
9657 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9659 Integer overflow and signedness fixes (Bug#8873).
9660 A few related buffer overrun fixes, too.

9664 * dispextern.h (struct face.stipple):
9665 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9666 (x_bitmap_mask, x_allocate_bitmap_record)
9667 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9668 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9669 (x_create_bitmap_from_xpm_data):
9670 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9671 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9673 * xfaces.c (load_pixmap):
9674 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9675 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9676 (.bitmaps_last, struct x_output.icon_bitmap):
9677 Use ptrdiff_t, not int, for bitmap indexes.
9678 (x_allocate_bitmap_record): Check for size overflow.
9679 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9681 Use ptrdiff_t, not int, for overlay counts.
9682 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9683 * editfns.c (overlays_around, get_pos_property):
9684 * textprop.c (get_char_property_and_overlay):
9685 * xdisp.c (next_overlay_change, note_mouse_highlight):
9686 * xfaces.c (face_at_buffer_position):
9687 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9688 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9689 (Fnext_overlay_change, Fprevious_overlay_change)
9690 (mouse_face_overlay_overlaps, Foverlays_in):
9691 Use ptrdiff_t, not int, for sizes.
9692 (overlays_at, overlays_in): Check for size-calculation overflow.
9694 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9696 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9697 (x_session_initialize): Do not assume string length fits in int.
9699 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9700 This is unlikely, but can occur if DPI is outlandish.
9702 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9703 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9705 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9706 * xrdb.c (magic_file_p, search_magic_path):
9707 Omit last arg SUFFIX; it was always 0. All callers changed.
9708 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9710 * xfont.c (xfont_match): Avoid need for strlen.
9712 * xfns.c: Don't assume strlen fits in int.
9713 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9715 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9716 not unsigned long, as we prefer signed integers. All callers changed.
9717 Detect integer overflow in repeat count.
9718 (message_dolog): Don't assume print length fits in 39 bytes.
9719 (display_mode_element): Don't assume strlen fits in int.
9721 * termcap.c: Don't assume sizes fit in int and never overflow.
9722 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9723 (gobble_line): Check for size-calculation overflow.
9725 * minibuf.c (Fread_buffer):
9726 * lread.c (intern, intern_c_string):
9727 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9728 Don't assume string length fits in int.
9730 * keyboard.c (parse_tool_bar_item):
9731 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9733 * font.c: Don't assume string length fits in int.
9734 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9735 Use ptrdiff_t, not int.
9736 (font_intern_prop): Don't assume string length fits in int.
9737 Don't assume integer property fits in fixnum.
9738 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9740 * filelock.c: Fix some buffer overrun and integer overflow issues.
9741 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9742 Reformulate so as not to need the command string.
9743 Invoke gzip -cd rather than gunzip, as it's more portable.
9744 (lock_info_type, lock_file_1, lock_file):
9745 Don't assume pid_t and time_t fit in unsigned long.
9746 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9747 (current_lock_owner): Prefer signed type for sizes.
9748 Use memcpy, not strncpy, where memcpy is what is really wanted.
9749 Don't assume (via atoi) that time_t and pid_t fit in int.
9750 Check for time_t and/or pid_t out of range, e.g., via a network share.
9751 Don't alloca where an auto var works fine.
9753 * fileio.c: Fix some integer overflow issues.
9754 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9755 Don't assume string length fits in int.
9756 (directory_file_name): Don't assume string length fits in long.
9757 (make_temp_name): Don't assume pid fits in int, or that its print
9758 length is less than 20.
9760 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9762 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9764 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9766 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9767 We prefer signed integers, even for size calculations.
9769 * emacs.c: Don't assume string length fits in 'int'.
9770 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9771 (main): Don't invoke strlen when not needed.
9773 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9774 (XD_DEBUG_MESSAGE): Don't waste a byte.
9776 * callproc.c (getenv_internal_1, getenv_internal)
9778 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9780 * lread.c (invalid_syntax): Omit length argument.
9781 All uses changed. This doesn't fix a bug, but it simplifies the
9782 code away from its former Hollerith-constant appearance, and it's
9783 one less 'int' to worry about when looking at integer-overflow issues.
9784 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9786 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9787 This didn't break anything, but it didn't help either.
9788 It's confusing to put a bogus integer in a place where the actual
9789 value does not matter.
9790 (LIST_END_P): Remove unused macro and its bogus comment.
9791 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9793 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9794 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9796 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9797 We prefer signed types, and the value cannot exceed the EMACS_INT
9798 range anyway (because otherwise the length would not be representable).
9799 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9800 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9801 This avoids a GCC warning when WIDE_EMACS_INT.
9803 * indent.c (sane_tab_width): New function.
9804 (current_column, scan_for_column, Findent_to, position_indentation)
9805 (compute_motion): Use it. This is just for clarity.
9806 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9808 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9810 * lisp.h (lint_assume): New macro.
9811 * composite.c (composition_gstring_put_cache):
9812 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9814 * editfns.c, insdel.c:
9815 Omit unnecessary forward decls, to simplify future changes.
9817 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9819 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9821 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9822 Use much-faster test for byte-length change.
9823 Don't assume string byte-length fits in 'int'.
9824 Check that character arg fits in 'int'.
9825 (mapcar1): Declare byte as byte, for clarity.
9827 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9829 * fns.c (concat): Catch string overflow earlier.
9830 Do not rely on integer wraparound.
9832 * dispextern.h (struct it.overlay_strings_charpos)
9833 (struct it.selective): Now EMACS_INT, not int.
9834 * xdisp.c (forward_to_next_line_start)
9835 (back_to_previous_visible_line_start)
9836 (reseat_at_next_visible_line_start, next_element_from_buffer):
9837 Don't arbitrarily truncate the value of 'selective' to int.
9839 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9841 * composite.c: Don't truncate sizes to 'int'.
9842 (composition_gstring_p, composition_reseat_it)
9843 (composition_adjust_point): Use EMACS_INT, not int.
9844 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9845 not EMACS_UINT, for indexes.
9847 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9849 * buffer.c: Include <verify.h>.
9850 (struct sortvec.priority, struct sortstr.priority):
9851 Now EMACS_INT, not int.
9852 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9853 (struct sortstr.size, record_overlay_string)
9854 (struct sortstrlist.size, struct sortlist.used):
9855 Don't truncate size to int.
9856 (record_overlay_string): Check for size-calculation overflow.
9857 (init_buffer_once): Check at compile-time, not run-time.
9859 2011-06-22 Jim Meyering <meyering@redhat.com>
9861 Don't leak an XBM-image-sized buffer
9862 * image.c (xbm_load): Free the image buffer after using it.
9864 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9867 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9868 that Sun C diagnosed.
9869 * fns.c (secure_hash): Fix pointer signedness issue.
9870 * intervals.c (static_offset_intervals): New function.
9871 (offset_intervals): Use it.
9873 2011-06-21 Leo Liu <sdl.web@gmail.com>
9876 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9879 * fns.c (secure_hash): Rename from crypto_hash_function and change
9880 the first arg to accept symbols.
9881 (Fsecure_hash): New primitive.
9882 (syms_of_fns): New symbols.
9884 2011-06-20 Deniz Dogan <deniz@dogan.se>
9886 * process.c (Fset_process_buffer): Clarify return value in
9889 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9891 * dispnew.c (add_window_display_history): Use BVAR.
9893 * xdisp.c (debug_method_add): Use BVAR.
9894 (check_window_end, dump_glyph_matrix, dump_glyph)
9895 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9897 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9900 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9901 check till after the cache is created in init_frame_faces.
9903 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9905 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9907 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9909 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9910 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9911 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9913 Improve buffer-overflow checking (Bug#8873).
9914 * fileio.c (Finsert_file_contents):
9915 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9916 Remove the old (too-loose) buffer overflow checks.
9917 They weren't needed, since make_gap checks for buffer overflow.
9918 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9919 The old code merely checked for Emacs fixnum overflow, and relied
9920 on undefined (wraparound) behavior. The new code avoids undefined
9921 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9923 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9924 Tune. Don't use wider integers than needed. Don't use alloca.
9925 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9927 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9929 * insdel.c, lisp.h (buffer_overflow): New function.
9930 (insert_from_buffer_1, replace_range, replace_range_2):
9931 * insdel.c (make_gap_larger):
9932 * editfns.c (Finsert_char):
9933 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9935 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9937 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9939 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9941 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9942 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9944 * fileio.c: Don't assume EMACS_INT fits in off_t.
9945 (emacs_lseek): New static function.
9946 (Finsert_file_contents, Fwrite_region): Use it.
9947 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9949 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9951 * fns.c: Don't overflow int when computing a list length.
9952 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9953 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9954 truncation on 64-bit hosts. Check for QUIT every
9955 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9956 faster and is responsive enough.
9957 (Flength): Report an error instead of overflowing an integer.
9958 (Fsafe_length): Return a float if the value is not representable
9959 as a fixnum. This shouldn't happen except in contrived situations.
9960 (Fnthcdr, Fsort): Don't assume list length fits in int.
9961 (Fcopy_sequence): Don't assume vector length fits in int.
9963 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9964 (header_size, word_size): New constants.
9965 (allocate_vectorlike): Don't check size overflow here.
9966 (allocate_vector): Check it here instead, since this is the only
9967 caller of allocate_vectorlike that could cause overflow.
9968 Check that the new vector's length is representable as a fixnum.
9970 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9971 The previous code was bogus. For example, next_almost_prime (32)
9972 returned 39, which is undesirable as it is a multiple of 3; and
9973 next_almost_prime (24) returned 25, which is a multiple of 5 so
9974 why was the code bothering to check for multiples of 7?
9976 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9978 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9980 Variadic C functions now count arguments with ptrdiff_t.
9981 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9982 Back then I didn't know that the Emacs coding style prefers signed int.
9983 Also, in the meantime I found a few more instances where arguments
9984 were being counted with int, which may truncate counts on 64-bit
9985 machines, or EMACS_INT, which may be unnecessarily wide.
9986 * lisp.h (struct Lisp_Subr.function.aMANY)
9987 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9988 Arg counts are now ptrdiff_t, not size_t.
9989 All variadic functions and their callers changed accordingly.
9990 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9991 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9992 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9993 * callint.c (Fcall_interactively): Check arg count for overflow,
9994 to avoid potential buffer overrun. Use signed char, not 'int',
9995 for 'varies' array, so that we needn't bother to check its size
9996 calculation for overflow.
9997 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9998 * eval.c (apply_lambda):
9999 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10000 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10001 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10003 * callint.c (Fcall_interactively): Don't use index var as event count.
10005 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10006 * mem-limits.h (SIZE): Remove; no longer used.
10008 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10010 Remove unnecessary casts.
10011 * xterm.c (x_term_init):
10012 * xfns.c (x_set_border_pixel):
10013 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10014 These aren't needed now that we assume ANSI C.
10016 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10017 It's more likely to cause problems (due to unsigned overflow)
10020 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10022 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10024 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10026 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10028 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10030 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10032 GLYPH_CODE_FACE returns EMACS_INT, not int.
10033 * dispextern.h (merge_faces):
10034 * xfaces.c (merge_faces):
10035 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10036 Don't assume EMACS_INT fits in int.
10038 * character.h (CHAR_VALID_P): Remove unused parameter.
10039 * fontset.c, lisp.h, xdisp.c: All uses changed.
10041 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10043 * fns.c (concat): Minor tuning based on overflow analysis.
10044 This doesn't fix any bugs. Use int to hold character, instead
10045 of constantly refetching from Emacs object. Use XFASTINT, not
10046 XINT, for value known to be a character. Don't bother comparing
10047 a single byte to 0400, as it's always less.
10049 * floatfns.c (Fexpt):
10050 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10052 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10055 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10057 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10058 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10059 incorrectly succeed when S was a string, because 4294967386 was
10060 truncated before it was used.
10062 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10063 Otherwise, an out-of-range integer could cause undefined behavior
10066 * composite.c: Use int, not EMACS_INT, for characters.
10067 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10068 EMACS_INT, for values that are known to be in character range.
10069 This doesn't fix any bugs but is the usual style inside Emacs and
10070 may generate better code on 32-bit machines.
10072 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10073 This is for reasons similar to the recent CHAR_STRING fix.
10074 * charset.c (Fencode_char): Check that character arg is actually
10075 a character. Pass an int to ENCODE_CHAR.
10076 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10077 wider than 'int', as a compile-time check to prevent future regressions
10080 * character.c (char_string): Remove unnecessary casts.
10082 Make sure a 64-bit char is never passed to CHAR_STRING.
10083 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10084 by silently ignoring the top 32 bits, allowing some values
10085 that were far too large to be valid characters.
10086 * character.h: Include <verify.h>.
10087 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10088 arguments are no wider than unsigned, as a compile-time check
10089 to prevent future regressions in this area.
10091 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10092 (Fsubst_char_in_region):
10094 * xdisp.c (decode_mode_spec_coding):
10095 Adjust to CHAR_STRING's new requirement.
10096 * editfns.c (Finsert_char, Fsubst_char_in_region):
10097 * fns.c (concat): Check that character args are actually
10098 characters. Without this test, these functions did the wrong
10099 thing with wildly out-of-range values on 64-bit hosts.
10101 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10102 These casts should not be needed on 32-bit hosts, either.
10103 * keyboard.c (read_char):
10104 * lread.c (Fload): Remove casts to unsigned.
10106 * lisp.h (UNSIGNED_CMP): New macro.
10107 This fixes comparison bugs on 64-bit hosts.
10108 (ASCII_CHAR_P): Use it.
10109 * casefiddle.c (casify_object):
10110 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10111 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10112 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10113 * dispextern.h (FACE_FROM_ID):
10114 * keyboard.c (read_char): Use UNSIGNED_CMP.
10116 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10117 not to EMACS_INT, to avoid GCC warning.
10119 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10121 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10122 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10123 isn't needed on 32-bit machines.
10125 * buffer.c (Fgenerate_new_buffer_name):
10126 Use EMACS_INT for count, not int.
10127 (advance_to_char_boundary): Return EMACS_INT, not int.
10129 * data.c (Qcompiled_function): Now static.
10131 * window.c (window_body_lines): Now static.
10133 * image.c (gif_load): Rename local to avoid shadowing.
10135 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10136 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10137 * alloc.c (make_save_value): Integer argument is now of type
10138 ptrdiff_t, not int.
10139 (mark_object): Use ptrdiff_t, not int.
10140 * lisp.h (pD): New macro.
10141 * print.c (print_object): Use it.
10143 * alloc.c: Use EMACS_INT, not int, to count objects.
10144 (total_conses, total_markers, total_symbols, total_vector_size)
10145 (total_free_conses, total_free_markers, total_free_symbols)
10146 (total_free_floats, total_floats, total_free_intervals)
10147 (total_intervals, total_strings, total_free_strings):
10148 Now EMACS_INT, not int. All uses changed.
10149 (Fgarbage_collect): Compute overall total using a double, so that
10150 integer overflow is less likely to be a problem. Check for overflow
10151 when converting back to an integer.
10152 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10153 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10154 These were 'int' variables that could overflow on 64-bit hosts;
10155 they were never used, so remove them instead of repairing them.
10156 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10157 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10158 Previously, this ceilinged at INT_MAX, but that doesn't work on
10160 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10162 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10163 (allocate_vectorlike): Check for ptrdiff_t overflow.
10164 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10165 when a (possibly-narrower) signed value would do just as well.
10166 We prefer using signed arithmetic, to avoid comparison confusion.
10168 * alloc.c: Catch some string size overflows that we were missing.
10169 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10170 for convenience in STRING_BYTES_MAX.
10171 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10172 The definition here is exact; the one in lisp.h was approximate.
10173 (allocate_string_data): Check for string overflow. This catches
10174 some instances we weren't catching before. Also, it catches
10175 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10176 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10177 and ptrdiff_t and EMACS_INT are both 64 bits.
10179 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10180 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10181 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10183 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10185 * alloc.c (Fmake_string): Check for out-of-range init.
10187 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10189 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10191 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10193 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

10204 and height if HAVE_GTK3 (Bug#8505).
10205 (scroll_bar_width_for_theme): New variable.
10206 (update_theme_scrollbar_width): New function.
10207 (xg_get_default_scrollbar_width): Move code to
10208 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

10211 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10213 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

10220 * window.c (temp_output_buffer_show): Call display_buffer with
10221 second argument Vtemp_buffer_show_specifiers and reset latter
10222 immediately after the call.
10223 (Vtemp_buffer_show_specifiers): New variable.
10224 (auto_window_vscroll_p, next_screen_context_lines)
10225 (Vscroll_preserve_screen_position): Remove leading asterisks from

10758 instead of using explicit *_CHAR codes.
10759 (bidi_resolve_explicit, bidi_resolve_weak):

10776 (display_prop_intangible_p): Reimplement to call
10777 handle_display_spec instead of single_display_spec_intangible_p.

10789 value of a `display' property is a "replacing spec".
10790 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10791 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10819 All callers changed. (Bug#8762)
10821 * gnutls.c: Use Emacs's memory allocators.
10822 Without this change, the gnutls library would invoke malloc etc.
10823 directly, which causes problems on non-SYNC_INPUT hosts, and which
10824 runs afoul of improving memory_full behavior. (Bug#8761)
10825 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10826 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10827 xfree instead of the default malloc, realloc, free.
10828 (Fgnutls_boot): No need to check for memory allocation failure,
10829 since xmalloc does that for us.

10854 Check for overflow in vector size calculations.
10855 * ccl.c (ccl_driver):
10856 Check for overflow when converting EMACS_INT to int.

10858 need to be updated by these changes.
10859 * fns.c (make_hash_table, maybe_resize_hash_table):
10860 Check for integer overflow with large hash tables.
10861 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10862 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10863 (SXHASH_REDUCE): New macro.
10864 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10865 Use it instead of discarding useful hash info with large hash values.
10866 (sxhash_float): New function.
10867 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10868 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10869 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10870 Rewrite to use FIXNUM_BITS, as this simplifies things.
10871 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10872 Adjust signatures to match updated version of code.
10873 (consing_since_gc): Now EMACS_INT, since a single hash table can
10874 use more than INT_MAX bytes.

10912 Use 'inline', not 'INLINE'.
10913 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10914 * alloc.c, fontset.c (INLINE): Remove.
10915 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10916 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10917 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10918 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10919 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10921 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10923 Make it possible to run ./temacs.
10925 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10926 syms_of_callproc does the same thing. Remove test for
10927 "initialized", do it in the caller.
10928 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10930 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10932 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10933 (read_minibuf): Use get_minibuffer.
10934 (syms_of_minibuf): Use DEFSYM.
10935 (Qmetadata): New var.
10936 * data.c (Qbuffer): Don't make it static.
10937 (syms_of_data): Use DEFSYM.
10939 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10941 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10942 (CCL_CODE_MIN): New macro.
10944 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10946 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10948 * eval.c (Qdebug): Now static.
10949 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10950 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10951 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10953 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10955 * image.c: Various fixes to ImageMagick code comments.
10956 (Fimagemagick_types): Doc fix.
10958 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10960 Minor fixes prompted by GCC 4.6.0 warnings.
10962 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10964 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10965 (x_clipboard_manager_save_all): Move extern decl to ...
10966 * xterm.h: ... here, so that it can be checked for consistency.
10968 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10970 * xselect.c (x_clipboard_manager_save_frame)
10971 (x_clipboard_manager_save_all): New functions.
10972 (Fx_clipboard_manager_save): Lisp function deleted.
10974 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10975 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10977 * xterm.h: Update prototype.
10979 2011-05-28 William Xu <william.xwl@gmail.com>
10981 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10982 exiting (Bug#8239).
10984 2011-05-28 Jim Meyering <meyering@redhat.com>
10986 Avoid a sign-extension bug in crypto_hash_function.
10987 * fns.c (to_uchar): Define.
10988 (crypto_hash_function): Use it to convert some newly-signed
10989 variables to unsigned, to avoid sign-extension bugs. For example,
10990 without this change, (md5 "truc") would evaluate to
10991 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10992 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10993 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10995 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10997 Integer overflow fixes.
10999 * dbusbind.c: Serial number integer overflow fixes.
11000 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11001 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11002 to hold a serial number that is too large for a fixnum.
11003 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11004 Check for serial numbers out of range. Decode any serial number
11005 that was so large that it became a float. (Bug#8722)
11007 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11008 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11009 Use XFASTINT rather than XUINT when numbers are nonnegative.
11010 (xd_append_arg, Fdbus_method_return_internal):
11011 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11012 arguments, check that Lisp number is nonnegative, rather than
11013 silently wrapping negative numbers around. (Bug#8722)
11014 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11017 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11019 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11021 ccl: Add integer overflow checks.
11022 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11023 (IN_INT_RANGE): New macros.
11024 (ccl_driver): Use them to check for integer overflow when
11025 decoding a CCL program. Many of the new checks are whether XINT (x)
11026 fits in int; it doesn't always, on 64-bit hosts. The new version
11027 doesn't catch all possible integer overflows, but it's an
11028 improvement. (Bug#8719)
11030 * alloc.c (make_event_array): Use XINT, not XUINT.
11031 There's no need for unsigned here.
11033 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11034 This follows up to the 2011-05-06 change that substituted uintptr_t
11035 for EMACS_INT. This case wasn't caught back then.
11037 Rework Fformat to avoid integer overflow issues.
11038 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11039 now (part of C89). Include <verify.h>.
11040 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11041 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11042 (Fformat): Avoid the prepass trying to compute sizes; it was only
11043 approximate and thus did not catch overflow reliably. Instead, walk
11044 through the format just once, formatting and computing sizes as we go,
11045 checking for integer overflow at every step, and allocating a larger
11046 buffer as needed. Keep track separately whether the format is
11047 multibyte. Keep only the most-recently calculated precision, rather
11048 than them all. Record whether each argument has been converted to
11049 string. Use EMACS_INT, not int, for byte and char and arg counts.
11050 Support field widths and precisions larger than INT_MAX. Avoid
11051 sprintf's undefined behavior with conversion specifications such as %#d
11052 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11053 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11054 formatting out-of-range floating point numbers with int
11055 formats. (Bug#8668)
11057 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11059 * data.c: Avoid integer truncation in expressions involving floats.
11060 * data.c: Include <intprops.h>.
11061 (arith_driver): When there's an integer overflow in an expression
11062 involving floating point, convert the integers to floating point
11063 so that the resulting value does not suffer from catastrophic
11064 integer truncation. For example, on a 64-bit host (* 4
11065 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11066 Do not rely on undefined behavior after integer overflow.
11068 merge count_size_as_multibyte, parse_str_to_multibyte
11069 * character.c, character.h (count_size_as_multibyte):
11070 Rename from parse_str_to_multibyte; all uses changed.
11071 Check for integer overflow.
11072 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11073 since it's now a duplicate of the other. This is more of
11074 a character than a buffer op, so better that it's in character.c.
11075 * fns.c, print.c: Adjust to above changes.
11077 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11079 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11081 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11083 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11084 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11085 (x_clipboard_manager_save): Now static.
11086 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11088 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11089 (crypto_hash_function): Now static.
11090 Fix pointer signedness problems. Avoid unnecessary initializations.
11092 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11094 * termhooks.h (Vselection_alist): Make it terminal-local.
11096 * terminal.c (create_terminal): Initialize it.
11098 * xselect.c: Support for clipboard managers.
11099 (Vselection_alist): Move to termhooks.h as terminal-local var.
11100 (LOCAL_SELECTION): New macro.
11101 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11102 (symbol_to_x_atom): Remove gratuitous arg.
11103 (x_handle_selection_request, lisp_data_to_selection_data)
11104 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11105 (x_own_selection, x_get_local_selection, x_convert_selection):
11106 New arg, specifying work frame. Use terminal-local Vselection_alist.
11107 (some_frame_on_display): Delete unused function.
11108 (Fx_own_selection_internal, Fx_get_selection_internal)
11109 (Fx_disown_selection_internal, Fx_selection_owner_p)
11110 (Fx_selection_exists_p): New optional frame arg.
11111 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11112 (x_handle_selection_clear): Don't treat other terminals with the
11113 same keyboard specially. Use the terminal-local Vselection_alist.
11114 (x_clear_frame_selections): Use Frun_hook_with_args.
11116 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11118 * xterm.h: Add support for those atoms.
11120 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11122 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11123 (converted_selections, conversion_fail_tag): New global variables.
11124 (x_selection_request_lisp_error): Free the above.
11125 (x_get_local_selection): Remove unnecessary code.
11126 (x_reply_selection_request): Args changed; handle arbitrary array
11127 of converted selections stored in converted_selections.
11128 Separate the XChangeProperty and SelectionNotify steps.
11129 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11130 (x_convert_selection): New function.
11131 (x_handle_selection_event): Simplify.
11132 (x_get_foreign_selection): Don't ignore incoming requests while
11133 waiting for an answer; this will fail when we implement
11134 SAVE_TARGETS, and seems unnecessary anyway.
11135 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11136 (Vx_sent_selection_functions): Doc fix.
11138 2011-05-26 Leo Liu <sdl.web@gmail.com>
11140 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11142 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11144 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11146 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11147 for fringe update if it has periodic bitmap.
11148 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11149 and fringe_bitmap_periodic_p.
11151 * fringe.c (get_fringe_bitmap_data): New function.
11152 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11153 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11154 row. Mark glyph row for fringe update if periodicity changed.
11156 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11157 for fringe update unless it has periodic bitmap.
11159 2011-05-25 Kenichi Handa <handa@m17n.org>
11161 * xdisp.c (get_next_display_element): Set correct it->face_id for
11162 a static composition.
11164 2011-05-24 Leo Liu <sdl.web@gmail.com>
11167 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11169 * fns.c (crypto_hash_function, Fsha1): New function.
11170 (Fmd5): Use crypto_hash_function.
11171 (syms_of_fns): Add Ssha1.
11173 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11175 * gnutls.c: Remove unused macros.
11176 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11177 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11178 Remove macros that are defined and never used.
11179 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11181 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11183 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11184 (Fx_get_selection_internal): Minor cleanup.
11185 (Fx_own_selection_internal): Rename arguments for consistency with
11188 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11190 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11192 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11194 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11196 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11198 * dispnew.c (scrolling_window): Don't exclude the case that the
11199 last enabled row in the desired matrix touches the bottom boundary.
11201 2011-05-21 Glenn Morris <rgm@gnu.org>
11203 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11204 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11205 and add some more files.
11207 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11209 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11210 report_file_error introduced by the change from 2011-05-07.
11212 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11214 * systime.h (Time): Define only if emacs is defined.
11215 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11216 where the include path doesn't have X11/X.h by default. See
11217 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11219 2011-05-20 Kenichi Handa <handa@m17n.org>
11221 * composite.c (find_automatic_composition): Fix previous change.
11223 2011-05-20 Glenn Morris <rgm@gnu.org>
11225 * lisp.mk: New file, split from Makefile.in.
11226 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11227 (shortlisp): Remove.
11228 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11230 2011-05-19 Glenn Morris <rgm@gnu.org>
11232 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11233 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11234 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11235 (lisp): Set the order to that of loadup.el.
11236 (shortlisp): Make it a copy of $lisp.
11237 (SOME_MACHINE_LISP): Remove.
11238 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11239 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11241 2011-05-18 Kenichi Handa <handa@m17n.org>
11243 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11244 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11245 (find_automatic_composition): Mostly rewrite for efficiency.
11247 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11249 * makefile.w32-in: Update dependencies.
11251 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11253 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11254 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11256 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11258 Fix some integer overflow issues, such as string length overflow.
11260 * insdel.c (count_size_as_multibyte): Check for string overflow.
11262 * character.c (lisp_string_width): Check for string overflow.
11263 Use EMACS_INT, not int, for string indexes and lengths; in
11264 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11265 the resulting string length overflows an EMACS_INT; instead,
11266 report a string overflow if no precision given. When checking for
11267 precision exhaustion, use a check that cannot possibly have
11268 integer overflow. (Bug#8675)
11269 * character.h (lisp_string_width): Adjust to new signature.
11271 * alloc.c (string_overflow): New function.
11272 (Fmake_string): Use it. This doesn't change behavior, but saves
11273 a few bytes and will simplify future changes.
11274 * character.c (string_escape_byte8): Likewise.
11275 * lisp.h (string_overflow): New decl.
11277 Fixups, following up to the user-interface timestamp change.
11278 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11279 for UI timestamps, instead of unsigned long.
11280 * msdos.c (mouse_get_pos): Likewise.
11281 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11282 * w32gui.h (Time): Define by including "systime.h" rather than by
11283 declaring it ourselves. (Bug#8664)
11285 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11286 * image.c (clear_image_cache): Likewise.
11288 * term.c (term_mouse_position): Don't assume time_t wraparound.
11290 Be more systematic about user-interface timestamps.
11291 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11292 and sometimes 'EMACS_UINT', to represent these timestamps.
11293 This change causes it to use 'Time' uniformly, as that's what X uses.
11294 This makes the code easier to follow, and makes it easier to catch
11295 integer overflow bugs such as Bug#8664.
11296 * frame.c (Fmouse_position, Fmouse_pixel_position):
11297 Use Time, not unsigned long, for user-interface timestamps.
11298 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11299 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11300 * keyboard.h (last_event_timestamp): Likewise.
11301 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11302 * menu.h (xmenu_show): Likewise.
11303 * term.c (term_mouse_position): Likewise.
11304 * termhooks.h (struct input_event.timestamp): Likewise.
11305 (struct terminal.mouse_position_hook): Likewise.
11306 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11307 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11308 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11309 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11310 what it was before.
11311 * menu.h, termhooks.h: Include "systime.h", for Time.
11313 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11314 Don't assume that the difference between two unsigned long values
11315 can fit into an integer. At this point, we know button_down_time
11316 <= event->timestamp, so the difference must be nonnegative, so
11317 there's no need to cast the result if double-click-time is
11318 nonnegative, as it should be; check that it's nonnegative, just in
11319 case. This bug is triggered when events are more than 2**31 ms
11320 apart (about 25 days). (Bug#8664)
11322 * xselect.c (last_event_timestamp): Remove duplicate decl.
11323 (x_own_selection): Remove needless cast to unsigned long.
11325 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11326 that always fit in int. Use a sentinel instead of a counter, to
11327 avoid a temp and to allay GCC's concerns about possible int overflow.
11328 * frame.h (struct frame): Use int for menu_bar_items_used
11329 instead of EMACS_INT, since it always fits in int.
11331 * menu.c (grow_menu_items): Check for int overflow.
11333 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11335 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11336 Before, the code was not consistent. These values cannot exceed
11337 2**31 - 1 so there's no need to make them unsigned.
11338 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11339 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11340 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11342 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11344 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11345 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11346 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11347 presumably because the widths might not match.
11349 * window.c (size_window): Avoid needless test at loop start.
11351 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11353 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11355 2011-05-12 Drew Adams <drew.adams@oracle.com>
11357 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11359 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11361 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11362 `width' to `bar_area_x' and `bar_area_width', respectively.
11363 (x_scroll_run): Take account of fringe background extension.
11365 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11366 Rename local vars `left' and `width' to `bar_area_x' and
11367 `bar_area_width', respectively.
11368 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11369 background extension.
11371 2011-05-10 Jim Meyering <meyering@redhat.com>
11373 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11375 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11377 * image.c (Finit_image_library): Return t for built-in image types,
11378 like pbm and xbm. (Bug#8640)
11380 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11382 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11384 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11386 * w32console.c (Fset_screen_color): Doc fix.
11387 (Fget_screen_color): New function.
11388 (syms_of_ntterm): Defsubr it.
11390 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11391 unlink the temporary file if Fcall_process didn't create it in the
11393 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11394 child process will be redirected to a file specified with `:file'.
11395 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11396 cue to call_process_cleanup not to close that handle.
11398 2011-05-07 Ben Key <bkey76@gmail.com>
11400 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11401 one of two shell specific rules, either bootstrap-temacs-CMD or
11402 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11403 to the previous implementation of the bootstrap-temacs rule.
11404 The bootstrap-temacs-CMD rule is similar to the previous
11405 implementation of the bootstrap-temacs rule except that it
11406 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11409 These changes, along with some changes to nt/configure.bat,
11410 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11411 earlier fix to add support for --cflags and --ldflags options
11412 that include quotes so that it works whether make uses cmd or
11415 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11417 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11418 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11420 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11421 a string. Handle both cases.
11422 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11423 (Fdbus_register_method): Use Qinvalid_function.
11425 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11427 * makefile.w32-in: Update dependencies.
11428 (LISP_H): Add inttypes.h and stdin.h.
11429 (PROCESS_H): Add unistd.h.
11431 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11433 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11434 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11436 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11438 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11440 * term.c (vfatal): Remove stray call to va_end.
11441 It's not needed and the C Standard doesn't allow it here anyway.
11443 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11444 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11446 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11449 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11451 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11453 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11455 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11457 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11459 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11460 * charset.c (Fdefine_charset_internal): Don't initialize
11461 charset.code_space[15]. The value was garbage, on hosts with
11462 32-bit int (Bug#8600).
11464 * lread.c (read_integer): Be more consistent with string-to-number.
11465 Use string_to_number to do the actual conversion; this avoids
11466 rounding errors and fixes some other screwups. Without this fix,
11467 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11468 (digit_to_number): Move earlier, for benefit of read_integer.
11469 Return -1 if the digit is out of range for the base, -2 if it is
11470 not a digit in any supported base. (Bug#8602)
11472 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11474 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11475 to match comment at start of function. This also removes a
11476 GCC warning about overflow in a 32+64-bit port.
11478 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11480 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11481 Reported by Stefan Monnier in
11482 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11483 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11484 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11486 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11487 (EMACS_UINTPTR): Likewise, with uintptr_t.
11489 * lisp.h: Prefer 64-bit EMACS_INT if available.
11490 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11491 on 32-bit hosts that have 64-bit int, so that they can access
11493 However, temporarily disable this change unless the temporary
11494 symbol WIDE_EMACS_INT is defined.
11496 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11498 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11499 This removes an assumption that EMACS_INT and long are the same
11500 width as pointers. The assumption is true for Emacs porting targets
11501 now, but we want to make other targets possible.
11502 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11503 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11504 In the rest of the code, change types of integers that hold casted
11505 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11506 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11507 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11508 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11509 No need to cast type when ORing.
11510 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11511 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11512 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11513 assume EMACS_INT is the same width as char *.
11514 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11515 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11516 Remove no-longer-needed casts.
11517 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11518 (xg_tool_bar_help_callback, xg_make_tool_item):
11519 Use EMACS_INTPTR to hold an integer
11520 that will be cast to void *; this can avoid a GCC warning
11521 if EMACS_INT is not the same width as void *.
11522 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11523 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11524 (current_message_1, set_message_1):
11525 Use a local to convert to proper width without a cast.
11526 * xmenu.c (dialog_selection_callback): Likewise.
11528 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11529 Also, don't assume VALBITS / RAND_BITS is less than 5,
11530 and don't rely on undefined behavior when shifting a 1 left into
11532 * lisp.h (get_random): Change signature to match.
11534 * lread.c (hash_string): Use size_t, not int, for hash computation.
11535 Normally we prefer signed values; but hashing is special, because
11536 it's better to use unsigned division on hash table sizes so that
11537 the remainder is nonnegative. Also, size_t is the natural width
11538 for hashing into memory. The previous code used 'int', which doesn't
11539 retain enough info to hash well into very large tables.
11540 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11542 * dbusbind.c: Don't possibly lose pointer info when converting.
11543 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11544 Use XPNTR rather than XHASH, so that the high-order bits of
11545 the pointer aren't lost when converting through void *.
11547 * eval.c (Fautoload): Don't double-shift a pointer.
11549 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11551 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11553 * gnutls.c (DEF_GNUTLS_FN):
11554 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11556 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11558 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11561 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11563 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11564 New version that can reserve upto 2GB of heap space.
11566 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11568 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

11575 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11577 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11578 Update dependencies.
11580 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11582 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11583 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11584 Remove unused parameter `fildes'.
11585 * process.c (read_process_output, send_process): Don't pass it.
11587 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11589 Fix previous change: the library cache is defined in w32.c.
11590 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11591 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11593 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11595 Implement dynamic loading of GnuTLS on Windows.
11597 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11598 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11599 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11602 * gnutls.c (Qgnutls_dll): Define.
11603 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11604 (gnutls_*): Declare function pointers.
11605 (init_gnutls_functions): New function to initialize function pointers.

11608 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11609 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11610 (emacs_gnutls_write, emacs_gnutls_read)
11611 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11612 (Fgnutls_available_p): New function.
11613 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

11625 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11626 (w32_delayed_load): Move from image.c. When loading a library, record
11627 its filename in the :loaded-from property of the library id.
11628 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11629 Initialize and staticpro them.
11630 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

11633 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11634 instead of gnutls_record_check_pending.
11636 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11638 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11640 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11641 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11644 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11646 * xterm.c (x_set_frame_alpha): Do not set property on anything

11669 * sysdep.c (wait_for_termination_1): Make static.
11670 (wait_for_termination, interruptible_wait_for_termination):
11671 Move after wait_for_termination_1.
11673 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11675 * sysdep.c (interruptible_wait_for_termination): New function
11676 which is like wait_for_termination, but allows keyboard
11679 * callproc.c (Fcall_process): Add (:file "file") as an option for
11681 (Fcall_process_region): Ditto.
11683 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11685 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11686 rather than `XVECTOR (FOO)->size'.
11688 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11689 inttypes.h, as a gnulib replacement is used if it not available in
11692 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11694 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11695 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11696 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11698 * coding.c (coding_alloc_by_realloc): Error out if destination
11699 will grow beyond MOST_POSITIVE_FIXNUM.
11700 (decode_coding_emacs_mule): Abort if there isn't enough place in

11713 * window.c (window_scroll_line_based): Use a marker instead of
11714 simple variables to record original value of point. (Bug#7952)
11716 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11717 produced by %s or %c overflows available buffer space. (Bug#8545)
11719 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11721 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11756 Improve `doprnt' and its usage. (Bug#8545)
11757 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11758 `format_end'. Remove support for %l as a conversion specifier.
11759 Don't use xrealloc. Improve diagnostics when the %l size modifier
11760 is used. Update the commentary.
11762 * eval.c (verror): Simplify calculation of size_t.
11764 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11767 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11769 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11772 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11774 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11775 This makes this file independent of the recent pseudovector change.
11777 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11779 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11781 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11782 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11783 Remove unused local.
11784 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11786 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11787 GCC 4.6.0 optimizes based on type-based alias analysis.
11788 For example, if b is of type struct buffer * and v of type struct
11789 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11790 != &v->size, and therefore "v->size = 1; b->size = 2; return
11791 v->size;" must therefore return 1. This assumption is incorrect
11792 for Emacs, since it type-puns struct Lisp_Vector * with many other
11793 types. To fix this problem, this patch adds a new type struct
11794 vectorlike_header that documents the constraints on layout of vectors
11795 and pseudovectors, and helps optimizing compilers not get fooled
11796 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11797 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11798 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11800 (XSETPVECTYPE): Rewrite in terms of new macro.
11801 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11802 This is a bit clearer, and further avoids the possibility of
11803 undesirable aliasing.
11804 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11805 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11806 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11807 since Lisp_Subr is a special case (no "next" field).
11808 (ASIZE): Now uses header.size rather than size.
11809 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11810 to avoid the hassle of writing XVECTOR (foo)->header.size.
11811 (struct vectorlike_header): New type.
11812 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11813 object, to help avoid aliasing.
11814 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11815 (SUBRP): Likewise, since Lisp_Subr is a special case.
11816 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11817 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11818 (struct Lisp_Hash_Table): Combine first two members into a single
11819 struct vectorlike_header member. All uses of "size" and "next" members
11820 changed to be "header.size" and "header.next".
11821 * buffer.h (struct buffer): Likewise.
11822 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11823 * frame.h (struct frame): Likewise.
11824 * process.h (struct Lisp_Process): Likewise.
11825 * termhooks.h (struct terminal): Likewise.
11826 * window.c (struct save_window_data, struct saved_window): Likewise.
11827 * window.h (struct window): Likewise.
11828 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11829 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11830 * buffer.c (init_buffer_once): Likewise.
11831 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11833 * process.c (Fformat_network_address): Use local var for size,
11836 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11838 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11839 * data.c (atof): Remove decl; no longer used or needed.
11840 (digit_to_number): Move to lread.c.
11841 (Fstring_to_number): Use new string_to_number function, to be
11842 consistent with how the Lisp reader treats infinities and NaNs.
11843 Do not assume that floating-point numbers represent EMACS_INT
11844 without losing information; this is not true on most 64-bit hosts.
11845 Avoid double-rounding errors, by insisting on integers when
11846 parsing non-base-10 numbers, as the documentation specifies.
11847 * lisp.h (string_to_number): New decl, replacing ...
11848 (isfloat_string): Remove.
11849 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11850 (read1): Do not accept +. and -. as integers; this
11851 appears to have been a coding error. Similarly, do not accept
11852 strings like +-1e0 as floating point numbers. Do not report
11853 overflow for integer overflows unless the base is not 10 which
11854 means we have no simple and reliable way to continue.
11855 Break out the floating-point parsing into a new
11856 function string_to_number, so that Fstring_to_number parses
11857 floating point numbers consistently with the Lisp reader.
11858 (digit_to_number): Move here from data.c. Make it static inline.
11859 (E_CHAR, EXP_INT): Remove, replacing with ...
11860 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11861 (string_to_number): New function, replacing isfloat_string.
11862 This function checks for valid syntax and produces the resulting
11863 Lisp float number too. Rework it so that string-to-number
11864 no longer mishandles examples like "1.0e+". Use strtoumax,
11865 so that overflow for non-base-10 numbers is reported only when
11866 there's no portable and simple way to convert to floating point.
11868 * textprop.c (set_text_properties_1): Rewrite for clarity,
11869 and to avoid GCC warning about integer overflow.
11871 * intervals.h (struct interval): Use EMACS_INT for members
11872 where EMACS_UINT might cause problems. See
11873 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11874 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11875 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11877 (offset_intervals): Tell GCC not to worry about length overflow
11878 when negating a negative length.
11880 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11881 (overrun_check_free): Likewise.
11883 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11884 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11887 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11888 (gnutls_make_error): Rename local to avoid shadowing.
11889 (gnutls_emacs_global_deinit): ifdef out; not used.
11890 (Fgnutls_boot): Use const for pointer to readonly storage.
11891 Comment out unused local. Fix pointer signedness problems.
11893 * lread.c (openp): Don't stuff size_t into an 'int'.
11894 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11895 about possible signed overflow.
11897 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11898 (GDK_KEY_g): Don't define if already defined.
11899 (xg_prepare_tooltip): Avoid pointer signedness problem.
11900 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11902 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11903 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11905 * xfns.c (Fx_window_property): Simplify a bit,
11906 to make a bit faster and to avoid GCC 4.6.0 warning.
11907 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11909 * fns.c (internal_equal): Don't assume size_t fits in int.
11911 * alloc.c (compact_small_strings): Tighten assertion a little.
11913 Replace pEd with more-general pI, and fix some printf arg casts.
11914 * lisp.h (pI): New macro, generalizing old pEd macro to other
11915 conversion specifiers. For example, use "...%"pI"d..." rather
11916 than "...%"pEd"...".
11917 (pEd): Remove. All uses replaced with similar uses of pI.
11918 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11919 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11920 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11921 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11922 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11923 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11924 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11926 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11927 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11928 * print.c (safe_debug_print, print_object): Likewise.
11929 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11931 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11932 avoiding the 0 flag, which is not portable.
11933 * process.c (Fmake_network_process): Use pI to avoid cast.
11934 * region-cache.c (pp_cache): Likewise.
11935 * xdisp.c (decode_mode_spec): Likewise.
11936 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11937 behavior on 64-bit hosts with printf arg.
11938 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11939 (x_stop_queuing_selection_requests): Likewise.
11940 (x_get_window_property): Don't truncate byte count to an 'int'
11943 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11944 here, since it parses constructs like leading '-' and spaces,
11945 which are not wanted; and it overflows with large numbers.
11946 Instead, simply match F[0-9]+, which is what is wanted anyway.
11948 * alloc.c: Remove unportable assumptions about struct layout.
11949 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11950 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11951 (allocate_vectorlike, make_pure_vector): Use the new macros,
11952 plus offsetof, to remove unportable assumptions about struct layout.
11953 These assumptions hold on all porting targets that I know of, but
11954 they are not guaranteed, they're easy to remove, and removing them
11955 makes further changes easier.
11957 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11958 This doesn't fix a bug but makes the code clearer.
11959 (string_overrun_cookie): Now const. Use initializers that
11960 don't formally overflow signed char, to avoid warnings.
11961 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11962 can cause Emacs to crash when string overrun checking is enabled.
11963 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11964 multiple of sizeof (EMACS_INT); it need not be, if
11965 alignof(EMACS_INT) < sizeof (EMACS_INT).
11966 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11968 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11975 supposed to be handshaking. (Bug#8556)
11976 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11978 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

11984 matches the current signal symbol.
11986 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11988 * alloc.c (check_sblock, check_string_bytes)
11989 (check_string_free_list): Convert to standard C.
11991 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11993 * w32.c (emacs_gnutls_push): Fix typo.
11995 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11997 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11998 "cast to pointer from integer of different size".
12000 Improve doprnt and its use in verror. (Bug#8545)
12001 * doprnt.c (doprnt): Document the set of format control sequences
12002 supported by the function. Use SAFE_ALLOCA instead of always
12005 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12006 is one byte too soon. Don't use xrealloc; instead xfree and
12009 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12011 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12014 * gnutls.c: Renamed global_initialized to
12015 gnutls_global_initialized. Added internals for the
12016 :verify-hostname-error, :verify-error, and :verify-flags
12017 parameters of `gnutls-boot' and documented those parameters in the
12018 docstring. Start callback support.
12019 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12020 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12021 on error. Return error code.

12088 <char-direction-table>: Deleted.
12090 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12092 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12093 * doprnt.c: Include limits.h.
12094 (SIZE_MAX): New macro.
12095 (doprnt): Return a size_t value. 2nd arg is now size_t.
12096 Many local variables are now size_t instead of int or unsigned.
12097 Improve overflow protection. Support `l' modifier for integer
12098 conversions. Support %l conversion. Don't assume an EMACS_INT
12099 argument for integer conversions and for %c.
12101 * lisp.h (doprnt): Restore prototype.
12103 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12104 $(SRC)/character.h.
12106 * Makefile.in (base_obj): Add back doprnt.o.
12108 * deps.mk (doprnt.o): Add back prerequisites.
12109 (callint.o): Depend on character.h.
12111 * eval.c (internal_lisp_condition_case): Include the handler
12112 representation in the error message.
12113 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12114 when breaking from the loop.
12116 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12118 * callint.c (Fcall_interactively): When displaying error message
12119 about invalid control letter, pass the character's codepoint, not
12120 a pointer to its multibyte form. Improve display of the character
12121 in octal and display also its hex code.
12123 * character.c (char_string): Use %x to display the (unsigned)
12124 codepoint of an invalid character, to avoid displaying a bogus
12127 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12128 `error', not SYMBOL_NAME itself.
12130 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12131 character arguments to `error'.
12133 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12134 to `error' in error message about FINAL_CHAR argument. Make sure
12135 FINAL_CHAR is a character, and use %c when it is passed as
12136 argument to `error'.

12200 Define only if needed.
12202 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12203 by pacifying GCC about it. Maybe it's time to retire it?
12204 * xfaces.c (USG, __TIMEVAL__): Likewise.
12206 * dispextern.h (struct redisplay_interface): Rename param
12207 to avoid shadowing.
12208 * termhooks.h (struct terminal): Likewise.
12209 * xterm.c (xembed_send_message): Likewise.
12211 * insdel.c (make_gap_smaller): Define only if
12212 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
12214 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
12217 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
12218 so that we aren't warned about unused symbols.
12220 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
12222 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
12224 * xfns.c (x_real_positions): Mark locals as initialized.

12671 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
12672 * ccl.c (Vccl_program_table): Now static.
12673 (check_ccl_update): Remove; unused.
12675 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
12676 * category.h: ... from here.
12677 * category.c (check_category_table, set_category_set): Now static.
12679 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
12680 * lisp.h: Remove these decls.
12682 * buffer.c (buffer_count): Remove unused var.
12684 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
12685 so that it's not optimized away.
12686 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12687 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12688 exported only to the debugger.
12690 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12691 * atimer.h (run_all_atimers): Remove; not exported.
12693 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12694 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12695 was inaccessible from Lisp.
12696 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12697 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12699 alloc.c: Import and export fewer symbols, and remove unused items.
12700 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12702 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12703 it's not optimized away by whole-program optimization.
12704 (message_enable_multibyte, free_misc): Remove.
12705 (catchlist, handlerlist, mark_backtrace):
12706 Declare only if BYTE_MARK_STACK.
12707 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
12708 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
12709 (message_enable_multibyte): Remove decl.
12710 (free_misc, interval_free_list, float_block, float_block_index):
12711 (n_float_blocks, float_free_list, cons_block, cons_block_index):
12712 (cons_free_list, last_marked_index):
12714 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
12715 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12716 (mark_backtrace): Define only if BYTE_MARK_STACK.
12717 * xdisp.c (message_enable_multibyte): Now static.
12719 Declare Lisp_Object Q* variables to be 'static' if not exported.
12720 This makes it easier for human readers (and static analyzers)
12721 to see whether these variables are used from other modules.
12722 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12723 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12724 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

12727 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
12728 * xmenu.c, xselect.c:
12729 Declare Q* vars static if they are not used in other modules.
12730 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
12731 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12732 Remove decls of unexported vars.
12733 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12735 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12737 Make Emacs functions such as Fatom 'static' by default.
12738 This makes it easier for human readers (and static analyzers)
12739 to see whether these functions can be called from other modules.
12740 DEFUN now defines a static function. To make the function external
12741 so that it can be used in other C modules, use the new macro DEFUE.
12742 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12743 (Finit_image_library):
12744 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12745 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12746 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12747 Remove decls, since these functions are now static.
12748 (Funintern, Fget_internal_run_time): New decls, since these functions
12749 were already external.
12751 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12752 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12758 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12759 Mark functions with DEFUE instead of DEFUN,
12760 if they are used in other modules.
12761 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12762 decls for now-static functions.
12763 * buffer.h (Fdelete_overlay): Remove decl.
12764 * callproc.c (Fgetenv_internal): Mark as internal.

12771 (Funintern): Remove extern decl; now in .h file where it belongs.
12772 * fileio.c (Fmake_symbolic_link): New forward static decl.
12773 * image.c (Finit_image_library): New forward static decl.
12774 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12775 * intervals.h (Fprevious_property_change):
12776 (Fremove_list_of_text_properties): Remove decls.
12777 * keyboard.c (Fthis_command_keys): Remove decl.
12778 (Fcommand_execute): New forward static decl.
12779 * keymap.c (Flookup_key): New forward static decl.

12796 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12799 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12801 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12802 when at ZV. (Bug#8487)
12804 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12806 * charset.c (Fclear_charset_maps): Use xfree instead of free.

12809 * sound.c (sound_cleanup, alsa_close): Likewise.
12810 * termcap.c (tgetent): Likewise.
12811 * xfns.c (x_default_font_parameter): Likewise.
12812 * xsettings.c (read_and_apply_settings): Likewise.
12814 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12815 (overrun_check_free): Protoize.
12817 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12819 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12820 since callers should never pass a negative size.
12821 Change the signature to match that of plain 'read' and 'write'; see
12822 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12823 * lisp.h: Update prototypes of emacs_write and emacs_read.
12825 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12827 * xdisp.c (redisplay_window): Don't try to determine the character
12828 position of the scroll margin if the window start point w->startp
12829 is outside the buffer's accessible region. (Bug#8468)
12831 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12833 Fix write-region and its subroutines for buffers > 2GB.
12834 * fileio.c (a_write, e_write): Modify declaration of arguments and
12835 local variables to support buffers larger than 2GB.
12836 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12838 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12839 argument, local variables, and return value.
12841 * lisp.h: Update prototypes of emacs_write and emacs_read.
12843 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12845 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12847 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12849 Fix more problems found by GCC 4.6.0's static checks.
12851 * xdisp.c (vmessage): Use a better test for character truncation.
12853 * charset.c (load_charset_map): <, not <=, for optimization,
12854 and to avoid potential problems with integer overflow.
12855 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12856 * casetab.c (set_identity, shuffle): Likewise.
12857 * editfns.c (Fformat): Likewise.
12858 * syntax.c (skip_chars): Likewise.
12860 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12861 This also lets GCC 4.6.0 generate slightly better loop code.
12863 * callint.c (Fcall_interactively): <, not <=, for optimization.
12864 (Fcall_interactively): Count the number of arguments produced,
12865 not the number of arguments given. This is simpler and lets GCC
12866 4.6.0 generate slightly better code.
12868 * ftfont.c: Distingish more carefully between FcChar8 and char.
12869 The previous code passed unsigned char * to a functions like
12870 strlen and xstrcasecmp that expect char *, which does not
12871 conform to the C standard.
12872 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12873 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12874 char * when the C standard requires it.
12876 * keyboard.c (read_char): Remove unused var.
12878 * eval.c: Port to Windows vsnprintf (Bug#8435).
12879 Include <limits.h>.
12880 (SIZE_MAX): Define if the headers do not.
12881 (verror): Do not give up if vsnprintf returns a negative count.
12882 Instead, grow the buffer. This ports to Windows vsnprintf, which
12883 does not conform to C99. Problem reported by Eli Zaretskii.
12884 Also, simplify the allocation scheme, by avoiding the need for
12885 calling realloc, and removing the ALLOCATED variable.
12887 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12889 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12890 But keep the doprint source code for now, as we might revamp it
12891 and use it again (Bug#8435).
12892 * lisp.h (doprnt): Remove.
12893 * Makefile.in (base_obj): Remove doprnt.o.
12894 * deps.mk (doprnt.o): Remove.
12896 error: Print 32- and 64-bit integers portably (Bug#8435).
12897 Without this change, on typical 64-bit hosts error ("...%d...", N)
12898 was used to print both 32- and 64-bit integers N, which relied on
12899 undefined behavior.
12900 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12901 * lisp.h (error, verror): Mark as printf-like functions.
12902 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12903 Report overflow in size calculations when allocating printf buffer.
12904 Do not truncate output string at its first null byte.
12905 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12906 Truncate the output at a character boundary, since vsnprintf does not
12908 * charset.c (check_iso_charset_parameter): Convert internal
12909 character to string before calling 'error', since %c now has the
12911 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12912 overflow when computing char to be passed to 'error'. Do not
12913 pass Lisp_Object to 'error'; pass the integer instead.
12914 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12915 formatted with plain %d.
12917 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12919 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12921 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12923 * xterm.c (x_catch_errors): Remove duplicate declaration.
12925 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12927 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12929 2011-04-10 Jim Meyering <meyering@redhat.com>
12931 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12932 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12933 return ssize_t not "int", and use size_t as the buffer length.
12934 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12935 * gnutls.h: Update declarations.
12936 * process.c (read_process_output): Use ssize_t, to match.
12937 (send_process): Likewise.
12939 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12941 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12943 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12945 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12946 Use unsigned char, to match FcChar8 type definition.
12948 * xterm.c (handle_one_xevent):
12949 * xmenu.c (create_and_show_popup_menu):
12950 * xselect.c (x_decline_selection_request)
12951 (x_reply_selection_request): Avoid type-punned deref of X events.
12953 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12955 Fix some uses of `int' instead of EMACS_INT.
12956 * search.c (string_match_1, fast_string_match)
12957 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12958 (scan_buffer, find_next_newline_no_quit)
12959 (find_before_next_newline, search_command, Freplace_match)
12960 (Fmatch_data): Make some `int' variables be EMACS_INT.
12962 * xdisp.c (display_count_lines): 3rd argument and return value now
12963 EMACS_INT. All callers changed.
12964 (pint2hrstr): Last argument is now EMACS_INT.
12966 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12967 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12968 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12969 (decode_coding_utf_16, decode_coding_emacs_mule)

12971 (decode_coding_ccl, decode_coding_charset)
12972 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12973 (decode_coding_iso_2022, decode_coding_emacs_mule)
12974 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12975 <char_offset, last_offset>: Declare EMACS_INT.

12979 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12980 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12982 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12983 (encode_invocation_designation): Last argument P_NCHARS is now
12985 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12986 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12988 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12991 * ccl.c (Fccl_execute_on_string): Declare some variables
12994 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12996 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12998 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13000 * process.c (Fformat_network_address): Doc fix.
13002 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13004 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13006 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13008 * keyboard.c (read_char): Call Lisp function help-form-show,
13009 instead of using internal_with_output_to_temp_buffer.
13010 (Qhelp_form_show): New var.
13011 (syms_of_keyboard): Use DEFSYM macro.
13013 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13020 (list_processes_1): Delete.
13022 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13024 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13026 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13028 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13030 Fix more problems found by GCC 4.6.0's static checks.
13032 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13034 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13036 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13038 * xdisp.c (vmessage): Mark as a printf-like function.
13040 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13042 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13044 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13045 printf-like functions.
13046 (tiff_load): Add casts to remove these marks before passing them
13047 to system-supplied API.
13049 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13051 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13052 This avoids several warnings with gcc -Wstrict-overflow.
13053 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13054 directly, rather than having caller test rule sign. This avoids
13055 some unnecessary tests.
13056 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13057 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13058 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13060 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13061 (xfont_open): Avoid unnecessary tests.
13063 * composite.c (composition_gstring_put_cache): Use unsigned integer.

13072 by using the new macro.
13074 * textprop.c (set_text_properties_1): Change while to do-while,
13075 since the condition is always true at first.
13077 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13078 (interval_deletion_adjustment): Return unsigned value.
13081 * process.c (list_processes_1, create_pty, read_process_output):
13082 (exec_sentinel): Remove vars that were set but not used.
13083 (create_pty): Remove unnecessary "volatile"s.

13094 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13095 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13097 * print.c (print_error_message): Avoid int overflow.
13099 * font.c (font_list_entities): Redo for clarity,
13100 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

13110 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13111 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13112 can always succeed if overflow has undefined behavior.

13115 (wordify): Omit three unnecessary tests.
13117 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13118 All callers changed. This avoids the need for an unused var.
13120 * casefiddle.c (casify_region): Remove var that is set but not used.
13122 * dired.c (file_name_completion): Remove var that is set but not used.
13124 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13126 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13127 (Finsert_file_contents): Remove unnecessary code checking fd.
13129 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13130 Check for integer overflow on size calculations.
13132 * buffer.c (Fprevious_overlay_change): Remove var that is set
13135 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13136 Remove vars that are set but not used.
13137 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13138 (timer_check_2): Mark vars as initialized.
13140 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13142 * image.c (lookup_image): Remove var that is set but not used.
13143 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13145 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13146 that are set but not used.
13148 * xfns.c (make_invisible_cursor): Don't return garbage
13149 if XCreateBitmapFromData fails (Bug#8410).
13151 * xselect.c (x_get_local_selection, x_handle_property_notify):
13152 Remove vars that are set but not used.
13154 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13155 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13157 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13158 Remove var that is set but not used.
13159 (scroll_bar_windows_size): Now size_t, not int.
13160 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13161 Check for overflow.
13163 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13164 (map_tty_color) [!defined MSDOS]: Likewise.
13166 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13168 * coding.c: Remove vars that are set but not used.
13169 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13170 All callers changed.
13171 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13172 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13173 (decode_coding_charset): Remove vars that are set but not used.
13175 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13176 that is set but not used.
13178 * print.c (print_object): Remove var that is set but not used.
13180 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13181 The gnulib version avoids calling malloc in the usual case,
13182 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13183 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13184 * filelock.c (current_lock_owner): Likewise.
13185 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13186 * sysdep.c: Include allocator.h, careadlinkat.h.
13187 (emacs_no_realloc_allocator): New static constant.
13188 (emacs_readlink): New function.
13189 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13190 ../lib/careadlinkat.h.
13192 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13194 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13195 first non-nil return value).

13204 * xdisp.c (display_count_lines): Remove parameter `start',
13205 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13206 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13207 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13209 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13210 and thereabouts. All callers changed.
13211 (get_per_char_metric): Remove parameter `f', unused since
13212 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13214 2011-04-02 Jim Meyering <meyering@redhat.com>
13216 do not dereference NULL upon failed strdup
13217 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13218 (ns_get_family): Likewise.
13220 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13222 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13224 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13226 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13229 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13231 Add lexical binding.
13233 * window.c (Ftemp_output_buffer_show): New fun.
13234 (Fsave_window_excursion):
13235 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13237 * lread.c (lisp_file_lexically_bound_p): New function.
13238 (Fload): Bind Qlexical_binding.
13239 (readevalloop): Remove `evalfun' arg.
13240 Bind Qinternal_interpreter_environment.
13241 (Feval_buffer): Bind Qlexical_binding.
13242 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13244 (syms_of_lread): Declare `lexical-binding'.
13246 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13248 * keyboard.c (eval_dyn): New fun.
13249 (menu_item_eval_property): Use it.
13251 * image.c (parse_image_spec): Use Ffunctionp.
13253 * fns.c (concat, mapcar1): Accept byte-code-functions.
13255 * eval.c (Fsetq): Handle lexical vars.
13256 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13257 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13258 (FletX, Flet): Obey lexical binding.
13259 (Fcommandp): Handle closures.
13260 (Feval): New `lexical' arg.
13261 (eval_sub): New function extracted from Feval. Use it almost
13262 everywhere where Feval was used. Look up vars in lexical env.
13264 (Ffunctionp): Move from subr.el.
13265 (Ffuncall): Handle closures.
13266 (apply_lambda): Remove `eval_flags'.
13267 (funcall_lambda): Handle closures and new byte-code-functions.
13268 (Fspecial_variable_p): New function.
13269 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13270 but without exporting it to Lisp.
13272 * doc.c (Fdocumentation, store_function_docstring):
13273 * data.c (Finteractive_form): Handle closures.
13275 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13278 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13280 (exec_byte_code): New function extracted from Fbyte_code to handle new
13281 calling convention for byte-code-functions. Add new byte-codes.
13283 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13285 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13287 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13289 * xdisp.c (redisplay_internal): Fix prototype.
13291 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13293 * xdisp.c (SCROLL_LIMIT): New macro.
13294 (try_scrolling): Use it when setting scroll_limit.
13295 Limit scrolling to 100 screen lines.
13296 (redisplay_window): Even when falling back on "recentering",
13297 position point in the window according to scroll-conservatively,
13298 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13300 (try_scrolling): When point is above the window, allow searching
13301 as far as scroll_max, or one screenful, to compute vertical
13302 distance from PT to the scroll margin position. This prevents
13303 try_scrolling from unnecessarily failing when
13304 scroll-conservatively is set to a value slightly larger than the
13305 window height. Clean up the case of PT below the margin at bottom
13306 of window: scroll_max can no longer be INT_MAX. When aggressive
13307 scrolling is in use, don't let point enter the opposite scroll
13308 margin as result of the scroll.
13309 (syms_of_xdisp) <scroll-conservatively>: Document the
13310 threshold of 100 lines for never-recentering scrolling.
13312 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13314 * dispextern.h (move_it_by_lines):

13317 (message_log_check_duplicate): Remove parameters `prev_bol' and
13318 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13319 (redisplay_internal): Remove parameter `preserve_echo_area',
13320 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13322 * indent.c (Fvertical_motion):
13323 * window.c (window_scroll_pixel_based, Frecenter):
13324 Don't pass `need_y_p' to `move_it_by_lines'.
13326 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13328 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13329 steal a few bits to be more compact.
13330 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13331 Remove unneeded casts.
13333 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13335 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13337 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13338 binding" message (bug#7967).
13340 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13342 Fix more problems found by GCC 4.6.0's static checks.
13344 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13345 Remove unused local var.
13347 * editfns.c (Fmessage_box): Remove unused local var.
13349 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13350 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13351 Omit unused local vars.
13352 * window.c (shrink_windows): Omit unused local var.
13353 * menu.c (digest_single_submenu): Omit unused local var.
13354 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13355 Omit unused local var.
13357 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13358 Don't assume string length fits in int.
13359 (keyremap_step, read_key_sequence): Use size_t for sizes.
13360 (read_key_sequence): Don't check last_real_key_start redundantly.
13362 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13363 instead of alloca (Bug#8344).
13365 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13366 (Fbacktrace_frame): Don't assume nframes fits in int.
13368 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13370 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13373 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13375 * cm.c (calccost): Turn while-do into do-while, for clarity.
13377 * keyboard.c (syms_of_keyboard): Use the same style as later
13378 in this function when indexing through an array. This also
13379 works around GCC bug 48267.
13381 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13383 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13385 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13386 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13388 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13389 This avoids undefined behavior on integer overflow, and is a bit
13390 more convenient anyway since it is compared to a size_t variable.
13392 Variadic C functions now count arguments with size_t, not int.
13393 This avoids an unnecessary limitation on 64-bit machines, which
13394 caused (substring ...) to crash on large vectors (Bug#8344).
13395 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13396 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13404 * fns.c (concat): Likewise.
13405 * frame.c (x_set_frame_parameters): Likewise.
13406 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13407 0 if not found, not -1. All callers changed.
13409 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13410 (stack_copy_size): Now size_t, not int.
13411 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13413 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13415 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13416 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13417 All callers changed.
13419 * lisp.h (multibyte_char_to_unibyte):
13420 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13421 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13432 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13433 don't set the hook to nil, but remove the offending function instead.
13434 (Qcommand_hook_internal): Remove, unused.
13435 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13436 Vcommand_hook_internal.
13438 * eval.c (enum run_hooks_condition): Remove.
13439 (funcall_nil, funcall_not): New functions.
13440 (run_hook_with_args): Call each function through a `funcall' argument.
13441 Remove `cond' argument, now redundant.

13454 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13455 All callers changed.
13457 * w32.c (_wsa_errlist): Use braces for struct initializers.
13459 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

13512 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
13514 * keyboard.c (timer_check): Remove parameter `do_it_now',
13515 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

13521 * xmenu.c (show_help_event, menu_help_callback):
13522 Adjust calls to `show_help_echo'.

13577 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
13579 * w32term.c (x_set_glyph_string_clipping):
13580 Don't pass uninitialized region to CombineRgn.

13606 * term.c (Fsuspend_tty, Fresume_tty):
13607 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13608 * window.c (temp_output_buffer_show):
13609 * insdel.c (signal_before_change):
13610 * frame.c (Fhandle_switch_frame):

13615 * callint.c (Fcall_interactively):
13616 * buffer.c (Fkill_all_local_variables):
13617 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13619 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13620 unconditionally since it does the check itself.
13622 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13624 Fix more problems found by GCC 4.5.2's static checks.
13626 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13627 the first time through the loop, since we know p0 < p1 then.
13628 This also avoids a gcc -Wstrict-overflow warning.
13630 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13631 leading to a memory leak, possible in functions like
13632 load_charset_map_from_file that can allocate an unbounded number
13633 of objects (Bug#8318).
13635 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13636 that could (at least in theory) be that large.
13638 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13639 This is less likely to overflow, and avoids undefined behavior if
13640 overflow does occur. All callers changed. Use strtoul to scan
13641 for the unsigned long integer.
13642 (pint2hrstr): Simplify and tune code slightly.
13643 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13645 * scroll.c (do_scrolling): Work around GCC bug 48228.
13646 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

13653 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13656 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13658 * process.c (Fmake_network_process): Use socklen_t, not int,
13659 where POSIX says socklen_t is required in portable programs.
13660 This fixes a porting bug on hosts like 64-bit HP-UX, where
13661 socklen_t is wider than int (Bug#8277).
13662 (Fmake_network_process, server_accept_connection):
13663 (wait_reading_process_output, read_process_output):
13666 * process.c: Rename or move locals to avoid shadowing.

13676 Make tparam.h and terminfo.c consistent.
13677 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13678 Include tparam.h instead, since it declares them.
13679 * cm.h (PC): Remove extern decl; tparam.h now does this.
13680 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13681 * terminfo.c: Include tparam.h, to check interfaces.
13682 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13683 (tparam): Adjust signature to match interface in tparam.h;
13684 this removes some undefined behavior. Check that outstring and len
13685 are zero, which they always are with Emacs.
13686 * tparam.h (PC, BC, UP): New extern decls.
13688 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13689 (xftfont_open): Rename locals to avoid shadowing.
13691 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13692 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

13703 * composite.c (composition_compute_stop_pos): Rename local to
13705 (composition_reseat_it): Remove unused locals.
13706 (find_automatic_composition, composition_adjust_point): Likewise.
13707 (composition_update_it): Mark var as initialized.
13708 (find_automatic_composition): Mark vars as initialized,
13709 with a FIXME (Bug#8290).

13713 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13714 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13715 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13716 to avoid shadowing.
13718 * textprop.c (property_change_between_p): Remove; unused.
13720 * intervals.c (interval_start_pos): Now static.
13722 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13725 Rename locals to avoid shadowing.
13727 * sound.c (wav_play, au_play, Fplay_sound_internal):
13728 Fix pointer signedness.
13729 (alsa_choose_format): Remove unused local var.
13730 (wav_play): Initialize a variable to 0, to prevent undefined
13731 behavior (Bug#8278).
13733 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13735 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13737 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13738 clobbering (Bug#8298).
13739 * sysdep.c (sys_subshell): Likewise.
13740 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13742 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13743 This should get cleaned up, so that child_setup has the
13744 same signature on all platforms.
13746 * callproc.c (call_process_cleanup): Now static.
13747 (relocate_fd): Rename locals to avoid shadowing.
13749 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13751 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13752 not to be necessary, and produces flickering.
13754 2011-03-20 Glenn Morris <rgm@gnu.org>
13756 * config.in: Remove file.
13758 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13760 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13761 are now in src/globals.h.
13762 (syms_of_minibuf): Remove spurious & from previous change.
13764 2011-03-20 Leo Liu <sdl.web@gmail.com>
13766 * minibuf.c (completing-read-function): New variable.
13767 (completing-read-default): Rename from completing-read.
13768 (completing-read): Call completing-read-function.
13770 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13772 * xfaces.c (Fx_load_color_file):
13773 Read color file from absolute filename (bug#8250).
13775 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13777 * makefile.w32-in: Update dependencies.
13779 2011-03-17 Eli Zaretskii <eliz@gnu.org>

13788 (sigchld_handler): Now static.
13790 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13791 That way, the code declares only the vars that it needs.

13802 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13803 Define only if needed.
13805 * unexelf.c (unexec): Name an expression,
13806 to avoid gcc -Wbad-function-cast warning.
13807 Use a different way to cause a compilation error if anyone uses
13808 n rather than nn, a way that does not involve shadowing.
13809 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13811 * deps.mk (unexalpha.o): Remove; unused.
13813 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13814 * unexec.h: New file.

13884 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13887 * lisp.h (eassert): Check that the argument compiles, even if
13888 ENABLE_CHECKING is not defined.
13890 * data.c (Findirect_variable): Name an expression, to avoid
13891 gcc -Wbad-function-cast warning.

13903 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13904 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13906 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13907 (GC_STRING_CHARS): Remove; not used.
13908 (Fmemory_limit): Cast sbrk's returned value to char *.
13910 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

13916 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13917 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13918 to use the following functions instead of these macros.
13919 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13920 EMACS_INT, since callers assume the returned value fits in int.
13921 (upcase1): Likewise, for UPCASE_TABLE.

13923 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13933 (regex_compile, re_match_2_internal): Mark locals as initialized.
13934 (RETALLOC_IF): Define only if needed.
13935 (WORDCHAR_P): Likewise. This one is never needed, but is used
13936 only in a comment talking about a compiler bug, so put inside
13937 the #if 0 of that comment.
13938 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13939 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

13965 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13966 New macros, so that the caller can use some names other than
13967 gcpro1, gcpro2, etc.
13968 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13970 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13971 argument, for consistency with GCPRO2_VAR, etc: it is now the
13972 prefix of the variable, not the variable itself. All uses
13974 * dired.c (directory_files_internal, file_name_completion):
13975 Rename locals to avoid shadowing.
13977 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13978 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13979 dired.c's scmp function, had undefined behavior.
13980 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13981 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13982 * buffer.h: ... to here, because these macros use current_buffer,
13983 and the new implementation with inline functions needs to have
13984 current_buffer in scope now, rather than later when the macros
13986 (downcase, upcase1): New static inline functions.
13987 (DOWNCASE, UPCASE1): Reimplement using these functions.
13988 This avoids undefined behavior in expressions like

14041 (MAXPATHLEN): Define only if needed.
14043 * process.c (serial_open, serial_configure): Move decls from here ...
14044 * systty.h: ... to here, so that they can be checked.

14407 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
14408 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
14409 (SHIFT_OUT_OK, ENCODE_CONTROL_SEQUENCE_INTRODUCER):
14410 (ENCODE_DIRECTION_R2L, ENCODE_DIRECTION_L2R):
14411 Remove unused macros.
14413 * category.c (hash_get_category_set): Remove unused local var.
14414 (copy_category_table): Now static, since it's not used elsewhere.

14439 Move these decls to tparam.h, and make them agree with what
14440 is actually in tparam.c. The previous trick of using incompatible
14441 decls in different modules does not conform to the C standard.
14442 All callers of tparam changed to use tparam's actual API.
