162 * alloc.c (listn): Fix the order the arguments are consed onto the
165 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
166 enumeration constants, as PURE and HEAP are too general, and clash
167 with other headers and sources, such as gmalloc.c and the
168 MS-Windows system headers. All users changed.
170 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

185 Improve GDB symbol export (Bug#12036).
186 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
187 arms of an 'if', not using conditional expressions; otherwise GDB
188 complains about the types in the unevaluated arm when the argument
189 is an integer literal.
190 (xgetint): Simplify expression.
191 * alloc.c (gdb_make_enums_visible): New constant. This ports to
192 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
193 Zaretskii in <http://bugs.gnu.org/12036#13>.
194 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer

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

254 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
255 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
256 not be usable in #if. This simplifies things.
258 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
260 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
262 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

265 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
266 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
267 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
268 Adjust to changes in lisp.h and emacs.c, by using
269 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
270 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
271 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
272 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
273 instead of gdb_valbits.
274 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
275 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
276 instead of gdb_array_mark_flag.
277 (xboolvector): Get size from $->size, not $->header.size.
278 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
279 (xreload, hook-run, hookpost-run): Remove.
280 * emacs.c: Include <verify.h>.
281 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
282 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
284 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
285 (gdb_USE_LSB_TAG): New enum constants.
286 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

289 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
290 as constants, so they're visible to GDB.
291 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

293 Now enum constants, not macros, so they're visible to GDB.
294 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
295 more convenient now. All uses changed.
296 (VALMASK) [USE_LSB_TAG]: Also define in this case.

307 add argument, tune behavior, and adjust all callers.
309 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
311 Use typedef for EMACS_INT, EMACS_UINT.
312 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
313 than macros. This simplifies debugging in the usual case, since
314 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
315 and it allows expressions involving EMACS_INT casts.
316 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
318 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

331 * buffer.c (Fkill_buffer): Adjust indirection counters when the
332 buffer is definitely dead. This should really fix an issue reported
333 by Christoph Scholtes again. (Bug#12007).
334 (init_buffer_once): Initialize indirection counters of
335 buffer_defaults and buffer_local_symbols (for sanity and safety).
337 2012-07-24 Eli Zaretskii <eliz@gnu.org>
339 * xdisp.c (init_iterator): Don't compute dimensions of truncation
340 and continuation glyphs on tooltip frames, leave them at zero.
341 Avoids continued lines in tooltips. (Bug#11832)
343 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
345 Simplify copy_overlay.
346 * buffer.c (copy_overlay): Simplify. Use build_marker.

370 Swap buffer text indirection counters in Fbuffer_swap_text.
371 * buffer.c (Fbuffer_swap_text): Swap indirections too.
372 This avoids crash reported by Christoph Scholtes at
373 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
375 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
377 * nsmenu.m (Popdown_data): New struct.
378 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
380 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

400 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
402 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
403 as it's limited by the amount of memory, not by INT_MAX.
405 2012-07-21 Eli Zaretskii <eliz@gnu.org>
407 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
408 in special-event-map. See the discussion at

955 glyph of a suitably computed width, to align the special glyphs at
956 the window margin. Code moved from display_line. (Bug#11832)

1131 * s/aix4-2.h (unix): Remove; no longer needed.
1133 EMACS_TIME simplification (Bug#11875).
1134 This replaces macros (which typically do not work in GDB)

1136 The functional style also makes code easier to read and maintain.
1137 * systime.h: Include <sys/time.h> on all hosts, not just if
1138 WINDOWSNT, since 'struct timeval' is needed in general.

1154 (add_emacs_time, sub_emacs_time): New functions.
1155 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1178 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1179 Prefer snprintf to strncpy.
1180 * nsterm.m (ns_term_init):
1181 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1182 * nsterm.m (ns_term_init):
1183 Avoid the need for strncpy, by using build_string or
1184 make_unibyte_string directly. Use dtoastr, not snprintf.
1185 * process.c (Fmake_network_process): Diagnose service names that
1186 are too long, rather than silently truncating them or creating
1187 non-null-terminated names.

1204 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1205 where argument type is known to be a Lisp_Cons.

1262 Stop ns builds setting the EMACSLOADPATH environment variable.
1263 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1264 Now it does not set EMACSLOADPATH, just returns the load-path string.

1266 * lread.c [HAVE_NS]: Include nsterm.h.
1267 (init_lread) [HAVE_NS]: Use ns_load_path.

1277 (ns_init_paths): Do not set EMACSPATH.

1337 Move marker debugging code under MARKER_DEBUG.
1338 * marker.c (MARKER_DEBUG): Move marker debugging code under

1379 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1380 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1381 Remove unused local.
1382 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1383 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1384 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1385 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1386 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1387 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1388 Fix pointer signedness problem.
1389 * xfaces.c (FRAME_X_FONT_TABLE):
1390 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1392 2012-07-07 Glenn Morris <rgm@gnu.org>
1394 * lread.c (load_path_check): New function, split from init_lread.
1395 (init_lread): Reorganize. Motivation:
1396 If EMACSLOADPATH is set, check/warn about that rather than the
1397 defaults, which we are not going to use. Hence we can remove
1398 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1399 Don't warn if site-lisp directories are missing.
1400 If not installed, start from a blank load-path, since
1401 PATH_LOADSEARCH refers to the eventual installation directories.
1403 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1405 Support truncation and continuation glyphs on GUI frames, when
1406 fringes are disabled. (Bug#11832)
1407 * xdisp.c (init_iterator): Get dimensions of truncation and
1408 continuation glyphs even if on GUI frames. Adjust
1409 it->last_visible_x on GUI frames when the left or right fringes,
1410 or both, are absent.
1411 (start_display, move_it_in_display_line_to): Handle the case of a
1412 GUI frame without a fringe to display continuation or truncation
1414 (insert_left_trunc_glyphs): Support GUI frames: make sure
1415 truncation glyphs overwrite enough glyphs from the current line to
1416 have sufficient space in pixels.
1417 (display_line): Support truncation and continuation glyphs on GUI
1418 frames. If some spare pixels are left on the line after inserting
1419 the truncation glyphs, fill that space with a stretch glyph of a
1420 suitably computed width.
1422 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1423 produce_glyphs, to support GUI sessions.
1425 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1427 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1429 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1431 Do not require float-time's arg to fit in time_t (Bug#11825).
1432 This works better on hosts where time_t is unsigned, and where
1433 float-time is applied to the (negative) difference between two times.
1434 * editfns.c (decode_time_components): Last arg is now double *,
1435 not int *, and means to store all the result as a double, without
1436 worrying about whether the seconds part fits in time_t.
1437 All callers changed.
1438 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1439 All callers changed.
1440 (Ffloat_time): Do not fail merely because the specified time falls
1441 outside of time_t range.
1443 2012-07-07 Glenn Morris <rgm@gnu.org>
1445 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1446 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

1451 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1452 Update dependencies.
1454 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1456 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1458 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1459 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1460 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1461 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1462 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1463 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1465 * xfont.c (compare_font_names): Redo to omit the need for casts.
1467 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1469 * xfns.c (Fx_change_window_property): Doc fix.
1470 * w32fns.c (Fx_change_window_property): Doc fix.
1472 * w32fns.c (Fx_window_property): Accept the same arguments as the
1473 X Windows version. Doc fix.
1474 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1476 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1477 Eli Zaretskii <eliz@gnu.org>
1479 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1480 Windows-specific code from nt/config.nt moved here.
1481 Obsolete settings removed.
1483 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1485 * process.c: Avoid unnecessary calls to gettime.
1486 (wait_reading_process_output): Don't get the time of day
1487 when gobbling data immediately and not waiting, as there's no need
1488 for it in that case. This removes a FIXME.
1490 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1492 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1493 is defined (Bug#11768).
1495 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1497 Fix marker debugging code.
1498 * marker.c (byte_char_debug_check): Do not perform the check
1499 if buffer is not multibyte.
1500 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1501 Call byte_char_debug_check with correct arguments.
1503 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1505 Compile marker debugging code only if ENABLE_CHECKING is defined.
1506 * marker.c (byte_char_debug_check, count_markers):
1507 Use only if ENABLE_CHECKING is defined.
1508 (byte_debug_flag): Remove.
1509 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1510 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1512 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1514 Avoid code repetition in marker-related functions.
1515 * marker.c (attach_marker): New function.
1516 (Fset_marker, set_marker_restricted, set_marker_both)
1517 (set_marker_restricted_both): Use it.
1518 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1519 Consistently rename charno to charpos.
1520 (marker_position): Add eassert.
1521 (marker_byte_position): Convert to eassert.
1523 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1525 Simplify list operations in unchain_overlay and unchain_marker.

1533 * lisp.h (build_marker): New prototype.
1534 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1535 * composite.c (autocmp_chars): Likewise.
1536 * editfns.c (buildmark): Remove.
1537 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1538 (save_restriction_save): Use build_marker.
1539 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1540 * window.c (save_window_save): Likewise.
1542 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1544 Do not use Fdelete_overlay in delete_all_overlays
1545 to avoid redundant calls to unchain_overlay.
1546 * buffer.c (drop_overlay): New function.
1547 (delete_all_overlays, Fdelete_overlay): Use it.
1548 * minibuf.c (get_minibuffer): Fix comment.
1550 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1552 Port to OpenBSD 5.1 amd64.
1553 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1554 This is needed for OpenBSD, and should be harmless on all BSD systems.
1555 Also, include <sys/sysctl.h>, as it should be available on all
1556 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1557 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1558 use p_pid member, not kp_proc.pid.
1560 2012-07-06 Glenn Morris <rgm@gnu.org>
1562 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1564 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1566 More xmalloc and related cleanup.
1567 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1568 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

1574 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1575 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1577 Omit needless casts involving void * pointers and allocation.
1578 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1579 as the former is more robust if P's type is changed.
1580 Prefer xzalloc to xmalloc + memset 0.
1581 Simplify malloc-or-realloc to realloc.
1582 Don't worry about xmalloc returning a null pointer.
1583 Prefer xstrdup to xmalloc + strcpy.
1584 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1586 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1587 alloca of a constant.
1589 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1591 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1592 hscroll is larger than the line width. Fixes long and futile
1593 looping inside extend_face_to_end_of_line (on a TTY) producing
1594 glyphs that are not needed and thrown away.
1596 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1598 * marker.c (set_marker_restricted_both): Simplify by using
1601 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

1610 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1611 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1612 followed by gtk_box_set_homogeneous (Bug#11768).
1613 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1614 (update_theme_scrollbar_width, xg_create_scroll_bar):
1615 Use gtk_scrollbar_new (Bug#11768).
1616 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1617 (is_box_type): New function (Bug#11768).
1618 (xg_tool_item_stale_p): Call is_box_type.
1619 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1620 with default display (Bug#11768).
1622 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1624 * xdisp.c (window_hscroll_limited): New function.
1625 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1626 coordinates when window's hscroll is set to insanely large
1629 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1631 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1632 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1634 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1637 * lisp.h (xzalloc): New prototype. Omit needless casts.
1638 * alloc.c (xzalloc): New function. Omit needless casts.

1690 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1692 * fileio.c (time_error_value): Check the right error number.
1693 Problem reported by Troels Nielsen in
1694 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1696 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1698 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1699 This should be fixed in a better way; see Eli Zaretskii in
1700 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1701 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1703 * fileio.c (time_error_value): Rename from special_mtime.
1704 The old name's problems were noted by Eli Zaretskii in
1705 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1707 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1708 This variable's comment says Emacs needs at least one GDB-visible
1709 symbol of type enum pvec_type, to work around GDB problems.
1710 The symbol's value doesn't matter.
1712 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1713 that causes compilation to fail on pre-C99 compilers.
1715 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1717 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1718 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1720 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1722 * buffer.c (init_buffer_once): Fix initialization of
1723 headers for buffer_defaults and buffer_local_symbols.
1724 Reported by Juanma Barranquero <lekktu@gmail.com>.
1726 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1728 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1729 * lisp.h (enum pvec_type): Use fewer bits.
1730 (PSEUDOVECTOR_SIZE_BITS): New constant.
1731 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1732 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1733 change in pvec_type.
1734 (PSEUDOVECTOR_TYPEP): New macro.
1735 (TYPED_PSEUDOVECTORP): Use it.
1736 * fns.c (internal_equal): Adapt code to extract pvectype.
1737 * emacs.c (gdb_pvec_type): Update type.
1738 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1739 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1740 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1741 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1742 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1743 abusing vector->header.next.nbytes.
1744 (live_vector_p): Use PVEC_TYPE.
1745 (mark_object): Adapt code to extract pvectype. Use switch.
1747 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1749 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1750 Tighten new eassert a bit.
1752 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1754 Fix compilation with --enable-gcc-warnings and -O1
1756 * doprnt.c (doprnt): Change type of tem to int, initialize
1757 to avoid compiler warning. Add eassert.
1758 * search.c (simple_search): Initialize match_byte to avoid
1759 compiler warning. Add eassert.
1761 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1763 Avoid weird behavior with large horizontal scrolls.
1764 Without this change, for example, large hscroll values would
1765 mess up Emacs's display on Fedora 15 x86, presumably due to
1766 overflows in int calculations in the display code.
1767 Also, if buffers had long lines, Emacs would freeze.
1768 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1769 (set_window_hscroll): New function, containing the old guts of
1770 Fset_window_hscroll. Return the clipped value.
1771 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1772 This avoids the need to check against PTRDIFF_MAX.
1774 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1776 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1778 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1780 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1782 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1783 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1784 since GCC 4.4.6 issues a bogus warning for them.
1786 Fix bugs in file timestamp newness comparisons.
1787 * fileio.c (Ffile_newer_than_file_p):
1788 * lread.c (Fload): Use full timestamp resolution of files,
1789 not just the 1-second resolution, so that files that are only
1790 slightly newer still count as newer.
1791 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1792 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1794 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1796 * fileio.c: Improve handling of file time marker. (Bug#11852)
1797 (special_mtime): New function.
1798 (Finsert_file_contents, Fverify_visited_file_modtime):
1799 Use it to set special mtime values consistently.
1801 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1803 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1804 marker for non-existing file. (Bug#11852)
1806 2012-07-03 Glenn Morris <rgm@gnu.org>
1808 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1809 and did not make it into globals.h).
1811 2012-07-03 Tom Tromey <tromey@redhat.com>
1813 * window.c (Fset_window_margins, Fset_window_fringes)

1849 2012-07-03 Glenn Morris <rgm@gnu.org>
1851 * lisp.h (Frandom): Make it visible to C.
1852 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1853 buffer for invisible buffers. (Bug#1229)

1857 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1858 values which aren't power of 2.
1859 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1860 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1863 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1865 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1867 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1869 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1871 * alloc.c (allocate_vector_block): Remove redundant
1872 calls to mallopt if DOUG_LEA_MALLOC is defined.
1873 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1874 avoid calls to mallopt if zero_vector is returned.
1876 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1878 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1879 is enabled, avoid dereferencing NULL current_sblock if
1882 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1884 Cleanup basic buffer management.
1885 * buffer.h (struct buffer): Change layout to use generic vector
1886 marking code. Fix some comments. Change type of 'clip_changed'
1887 to bitfield. Remove unused #ifndef old.
1888 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1889 (GET_OVERLAYS_AT): Fix indentation.
1890 (for_each_per_buffer_object_at): New macro.
1891 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

1894 * alloc.c (allocate_buffer): Adjust to match new layout of
1895 struct buffer. Fix comment.
1896 (mark_overlay): New function.

1898 Lisp area of struct buffer.
1899 (mark_object): Use it. Adjust marking of misc objects
1900 and related comments.
1902 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1904 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1905 wrapper that is not needed because the wrapped code is a no-op (zero
1906 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1907 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1909 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1911 * alloc.c (mark_buffer): Simplify. Remove prototype.
1912 (mark_object): Add comment. Reorganize marking of vector-like
1913 objects. Use CHECK_LIVE for all vector-like objects except buffers
1914 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1915 redundant calls to mark_vectorlike for bool vectors.
1917 2012-06-30 Glenn Morris <rgm@gnu.org>
1919 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1921 * epaths.in (PATH_SITELOADSEARCH): New.
1922 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1923 This is rather than relying on --enable-locallisppath elements
1924 having "site-lisp" in their names. (Bug#10208#25, 11658)
1926 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1928 * w32proc.c (sys_select): Accept and ignore one more argument.
1930 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1932 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1933 (pselect) [!MS_DOS]: Redirect to sys_select.
1935 * sysdep.c: Don't include dos.h and dosfns.h.
1937 * process.c (sys_select):
1938 * msdos.c (sys_select): Accept one more argument and ignore it.
1940 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1941 adapt data types and code to that.
1944 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1945 which clashes with the gnulib function of the same name.
1947 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1949 * font.c (font_style_to_value, font_style_symbolic)
1950 (font_prop_validate_style): Add type checks for values in
1953 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1955 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1958 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1960 * xdisp.c (try_window_id): Undo last change.
1962 * w32.c (getwd): Adjust commentary about startup_dir.
1963 (init_environment): Always call sys_access, even in non-MSVC
1964 builds. Don't chdir to the directory of the Emacs executable.
1965 This undoes code from 1997 which was justified by the need to
1966 "avoid conflicts when removing and renaming directories". But its
1967 downside was that every relative file name was being interpreted
1968 relative to the directory of the Emacs executable, which can never
1969 be TRT. In particular, it broke sys_access when called with
1970 relative file names.
1971 (sys_access): Map GetLastError to errno.
1973 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1975 * window.h (struct window): Change type of 'fringes_outside_margins'

1979 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1982 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

1985 Add QUIT to make the loop interruptible.
1987 2012-06-29 Glenn Morris <rgm@gnu.org>
1989 * charset.c (init_charset): Make lack of etc/charsets fatal.
1991 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1993 * editfns.c (region_limit): Fix type mismatch.
1995 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1997 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1998 undefined. Convert from xassert to eassert.
1999 * nsmenu.m: Convert from xassert to eassert.
2000 * nsterm.m: Likewise.
2002 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

2006 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2008 Avoid integer overflow on scroll-left and scroll-right.
2009 * window.c (HSCROLL_MAX): New macro.
2010 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

2015 * window.h (struct window): Change type of 'hscroll',
2016 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2017 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2018 Adjust users accordingly.
2019 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2020 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2021 from EMACS_INT to ptrdiff_t.
2022 (make_window): Omit redundant initialization.
2024 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2028 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2030 * window.h (struct window): Change type of 'use_time' and

2097 * alloc.c (allocate_string): Omit intervals initialization.
2098 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2099 as in make_pure_string and make_pure_c_string.

2157 a better opportunity to optimize away calls to strlen when the
2158 function is called with compile-time constant argument.
2159 * image.c (imagemagick_error): Convert to build_string.
2160 * w32proc.c (sys_spawnve): Likewise.

2163 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2165 Use sprintf return value instead of invoking strlen on result.
2166 In the old days this wasn't portable, since some sprintf
2167 implementations returned char *. But they died out years ago and
2168 Emacs already assumes sprintf returns int.
2169 Similarly for float_to_string.
2170 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2171 * ccl.c (ccl_driver):

2177 * xfns.c (syms_of_xfns):
2178 Use sprintf or float_to_string result to avoid need to call strlen.
2179 * data.c (Fnumber_to_string):
2180 Use make_unibyte_string, since the string must be ASCII.
2181 * lisp.h, print.c (float_to_string): Now returns int length.
2182 * term.c (produce_glyphless_glyph):
2183 Use sprintf result rather than recomputing it.
2185 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2186 * Makefile.in (ALL_CFLAGS):

2216 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2218 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2221 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2223 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2224 instead of truncating it to 63 (admittedly a generous limit).
2226 * process.c: Fix spelling and caps in comments.
2228 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2230 * emacs.c (setpgrp): Remove definition, unused.

2284 * keyboard.c (kbd_buffer_get_event):
2285 * process.c (Faccept_process_output):

2288 when time_t is unsigned and as wide as intmax_t.
2289 See <http://bugs.gnu.org/9000#51>.

2300 * makefile.w32-in: Update dependencies.

2307 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2308 Privately reported by Herbert J. Skuhra.
2309 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2311 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

2344 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
2346 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2347 Privately reported by Herbert J. Skuhra.
2348 [__FreeBSD__]: Remove "*/" typo after "#include".
2349 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2350 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2351 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2352 Don't assume EMACS_TIME and struct timeval are the same type.
2354 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2356 Support higher-resolution time stamps (Bug#9000).
2357 The time stamps are only nanosecond-resolution at the C level,
2358 since that's the best that any real-world system supports now.
2359 But they are picosecond-resolution at the Lisp level, as that's
2360 easy, and leaves room for future OS improvements.
2362 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2365 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2366 Don't get current time unless it's needed.
2368 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2369 now provides it if it's absent.
2370 (start_atimer): Port to higher-res time stamps.
2371 Check for time stamp overflow. Don't get current time more
2372 often than is needed.
2374 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2375 Include systime.h, not time.h.
2376 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

2382 (struct image): Timestamp now has higher resolution.
2384 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2385 has at least microseconds now. All uses removed.
2386 (update_frame, update_single_window, update_window, update_frame_1)
2387 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2389 * editfns.c (time_overflow): Now extern.
2390 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2396 (make_time): Now static.
2397 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2398 Report an error if the time is invalid, rather than having the caller
2401 * fileio.c: Include <stat-time.h>
2402 (Fcopy_file): Copy higher-resolution time stamps.
2403 Prefer to set the time stamp via a file descriptor if that works.

2405 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2406 (Fvisited_file_modtime, Fset_visited_file_modtime):
2407 Support higher-resolution time stamps.
2409 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2411 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2413 * image.c (prepare_image_for_display, clear_image_cache)
2414 (lookup_image): Port to higer-resolution time stamps.
2416 * keyboard.c (start_polling, bind_polling_period):
2417 Check for time stamp overflow.
2418 (read_char, kbd_buffer_get_event, timer_start_idle)
2419 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2420 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2421 Port to higher-resolution time stamps. Do not assume time_t is signed.
2422 (decode_timer): New function. Timers are now vectors of length 9,
2423 not 8, to accommodate the picosecond component.
2424 (timer_check_2): Use it.
2426 * nsterm.m (select_timeout, timeval_subtract): Remove.
2427 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2428 as they're a bit more accurate and handle overflow better.
2429 (ns_select): Change prototype to be compatible with pselect.
2430 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2431 * nsterm.h (ns_select): Adjust prototype.
2433 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2434 us-resolution time stamps.
2435 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2437 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2439 * lisp.h (time_overflow): New decl.
2440 (wait_reading_process_output): First arg is now intmax_t, not int,
2441 to accommodate larger waits.
2443 * process.h (struct Lisp_Process.read_output_delay):
2444 Now counts nanoseconds, not microseconds.
2445 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2447 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2448 (wait_reading_process_output):
2449 Port to ns-resolution time stamps.
2450 (Faccept_process_output, wait_reading_process_output):
2451 Check for time stamp overflow. Do not assume time_t is signed.
2452 (select_wrapper): Remove; we now use pselect.
2453 (Fprocess_attributes): Now generates ns-resolution time stamps.
2455 * sysdep.c: Include utimens.h. Don't include utime.h
2456 or worry about struct utimbuf; gnulib does that for us now.
2457 (gettimeofday): Remove; gnulib provides a substitute.
2458 (make_timeval): New function.
2459 (set_file_times): Now sets ns-resolution time stamps.
2460 New arg FD; all uses changed.
2461 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2462 (system_process_attributes):
2463 Now returns ns-resolution time stamp. All uses changed.
2464 Check for time stamp overflow.
2466 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2467 provides a substitute now.
2469 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2470 since it guarantees struct timespec.
2471 (EMACS_TIME): Now struct timespec, so that we can support
2472 ns-resolution time stamps.
2473 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2474 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2475 (EMACS_USECS): Remove.
2476 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2477 so multiply the arg by 1000 before storing it.
2478 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2480 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2481 Port to ns-resolution time stamps.
2482 (EMACS_TIME_NEG_P): Remove; replaced by....
2483 (EMACS_TIME_SIGN): New macro.

2485 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2486 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2487 (make_timeval, make_lisp_time, decode_time_components): New decls.
2488 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2489 that it mishandled time_t overflow. You can't compare by subtracting!
2490 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2491 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2493 * term.c: Include <sys/time.h>.
2494 (timeval_to_Time): New function, for proper overflow wraparound.

2502 (w32_get_internal_run_time):
2503 Port to higher-resolution Emacs time stamps.
2504 (ltime): Now accepts single 64-bit integer, as that's more convenient
2507 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2509 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2510 for compatibility with pselect. Support ns-resolution time stamps.
2512 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2514 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2515 Check for time stamp overflow, and support ns-resolution time stamps.
2517 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2518 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2519 (timeval_subtract): Remove; no longer needed.
2520 (XTflash, XTring_bell, x_wait_for_event):
2521 Port to ns-resolution time stamps. Don't assume time_t is signed.
2523 2012-06-22 Chong Yidong <cyd@gnu.org>

2527 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2529 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2530 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2531 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2532 staticidx goes up to 1597 out of 1600 = 0x640.)
2534 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2536 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2537 Otherwise, the umask might be mistakenly 0 while handling input signals.

2570 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2571 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2572 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2573 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2574 (METER_1, METER_2): Simplify.
2576 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

2580 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2582 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2583 gets killed during executing of this function (Bug#11665).
2584 Try to always return Qt when the buffer has been actually killed.
2585 (Vkill_buffer_query_functions): In doc-string say that functions
2586 run by this hook should not change the current buffer.
2588 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2590 Fix recently-introduced process.c problems found by static checking.

2608 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2610 * lisp.h (eassert): Assume C89 or later.
2611 This removes the need for CHECK.
2612 (CHECK): Remove. Its comments about always evaluating its
2613 argument were confusing, as 'eassert' typically does not evaluate
2616 * coding.c (produce_chars): Use ptrdiff_t, not int.
2618 * xterm.c (x_draw_underwave): Check for integer overflow.
2619 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2803 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2804 code works fine either way, and efficiency is not a concern here,
2805 as the union type is for debugging, not for production.
2806 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2807 Use an inline function on all platforms when using the union type,
2808 since this is simpler and 'static inline' can be used portably
2810 (LISP_INITIALLY_ZERO): New macro.
2811 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2812 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

2915 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2917 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2919 * alloc.c (allocate_vectorlike): Fix last change.

2950 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2952 * doprnt.c (doprnt): Truncate multibyte char correctly.
2953 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2954 would mishandle a string argument "Xc" if X was a multibyte
2955 character of length 2: it would truncate after X's first byte
2956 rather than including all of X.
2958 2012-06-06 Chong Yidong <cyd@gnu.org>
2960 * buffer.c (word_wrap): Doc fix.

3009 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3010 Convert pctcpu and pctmem to Lisp float properly.
3011 Let the compiler fold better, as 100.0/0x8000 is exact.
3013 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3015 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3018 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3020 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3022 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3024 For a 'struct window', replace some Lisp_Object fields to
3025 bitfields where appropriate, remove unused fields.
3026 * window.h (struct window): Remove unused 'last_mark_x' and
3027 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3028 change it's type from Lisp_Object to bitfield.
3029 Change type of 'force_start', 'optional_new_start',
3030 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3031 fields from Lisp_Object to bitfield. Adjust users accordingly.
3033 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3035 Pacify gcc -Wdouble-precision when using Xaw.
3036 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3037 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3038 Use 'float' consistently, rather than 'float' in most places
3039 and 'double' in a couple of places.
3041 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3043 * xdisp.c (handle_stop): Detect whether we have overlay strings
3044 loaded by testing it->current.overlay_string_index to be
3045 non-negative, instead of checking whether n_overlay_strings is
3046 positive. (Bug#11587)
3048 2012-05-31 Chong Yidong <cyd@gnu.org>
3050 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3052 * doc.c (Fsubstitute_command_keys): Doc fix.
3054 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3056 * search.c (search_buffer): Remove calls to
3057 r_alloc_inhibit_buffer_relocation, as it is now called by
3058 maybe_unify_char, which was the cause of relocation of buffer text
3061 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3063 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3064 for the duration of call to load_charset, to avoid problems with
3065 callers of maybe_unify_char that access buffer text through C
3068 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3069 decrement the inhibition flag, instead of just setting or
3072 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3074 Remove obsolete '#define static' cruft.
3075 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3076 This #undef was "temporary" in 2000; it is no longer needed
3077 now that '#define static' has gone away.
3078 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3079 (gray_bitmap_bits): Remove; no longer needed.
3080 All uses replaced with definiens.
3081 * xterm.c: Include "bitmaps/gray.xbm".
3083 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3085 Clean up __executable_start, monstartup when --enable-profiling.
3086 The following changes affect the code only when profiling.
3087 * dispnew.c (__executable_start): Rename from safe_bcopy.
3088 Define only on platforms that need it.
3089 * emacs.c: Include <sys/gmon.h> when profiling.
3090 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

3092 (safe_bcopy): Remove decl; no longer has that name.
3093 (main): Coalesce #if into single bit of code, for simplicity.

3123 Do not create empty overlays with the evaporate property (Bug#9642).
3124 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3125 Bug#9642, but explicitly check that the buffer the overlay would
3126 be moved to is live and rearrange lines to make sure that errors
3127 will not put the overlay in an inconsistent state.
3128 (Fdelete_overlay): Cosmetics.
3130 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3132 * w32term.c (my_bring_window_to_top): New function.
3133 (x_raise_frame): Use handle returned by DeferWindowPos, which

3144 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3146 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3147 This avoids undefined behavior that might cause the eassert
3148 to not catch an out-of-range value.
3150 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3152 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3164 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3166 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3167 Only r_alloc_inhibit_buffer_relocation needed to be added;
3168 the others were already declared.
3170 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3171 before checking whether it's out of range. Put the check inside
3173 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3175 2012-05-27 Ken Brown <kbrown@cornell.edu>
3177 * callproc.c (Fcall_process): Restore a line that was accidentally
3178 commented out in the 2011-02-13 change (bug#11547).

3182 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3183 defined on ralloc.c.
3185 * buffer.c [REL_ALLOC]: Remove prototypes of
3186 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3187 they are now on lisp.h.
3189 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3191 * search.c (search_buffer): Use it to inhibit relocation of buffer
3192 text while re_search_2 is doing its job, because re_search_2 is
3193 passed C pointers to buffer text. (Bug#11519)
3195 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3198 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3199 state after an additional call to move_it_in_display_line_to, keep
3200 the values of it->max_ascent and it->max_descent found for the
3202 (pos_visible_p): Revert the comparison against bottom_y to what it
3203 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3206 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3208 Fix coding-related core dumps with gcc -ftrapv.
3209 The code was computing A - B, where A and B are pointers, and B is
3210 random garbage. This can lead to core dumps on platforms that
3211 have special pointer registers, and it also leads to core dumps on
3212 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3213 A - B only when B is initialized properly.
3214 * coding.c (coding_set_source, coding_set_destination): Return void.
3215 (coding_change_source, coding_change_destinations): New functions,
3216 with the old behaviors of coding_set_source and coding_set_destination.
3217 All callers that need an offset changed to use these new functions.

3221 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3223 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3225 Extend mouse support on W32 text-mode console.
3226 * xdisp.c (draw_row_with_mouse_face):
3227 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3229 * w32console.c: Include window.h.
3230 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3232 (initialize_w32_display): Initialize mouse-highlight data.
3234 * w32inevt.c: Include termchar.h and window.h.
3235 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3236 moves, call note_mouse_highlight. If help_echo changed, call
3237 gen_help_event to produce help-echo message in the echo area.
3238 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3241 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3243 * lread.c (read1): Simplify slightly to avoid an overflow warning
3244 with GCC 4.7.0 on x86-64.
3246 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3248 * bidi.c (bidi_mirror_char): Revert last change: an int is
3249 definitely wide enough here.
3251 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3253 Fix integer width and related bugs (Bug#9874).

3260 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3261 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3263 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3264 (allocate_pseudovector):
3265 Use int, not EMACS_INT, where int is wide enough.
3266 (inhibit_garbage_collection, Fgarbage_collect):
3267 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3268 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3269 int might not be wide enough.
3270 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3273 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3274 (bidi_level_of_next_char, bidi_move_to_visually_next):
3275 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3288 (validate_region): Omit unnecessary test for b <= e,
3289 since that's guaranteed by the previous test.

3291 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)

3294 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3296 after the EMACS_INT -> ptrdiff_t change.

3298 * buffer.h: Adjust decls to match defn changes elsewhere.

3303 not int, to avoid needless 32-bit limit on 64-bit hosts.
3304 (exec_byte_code): Use tighter memory-full test, one that checks
3305 for alloca overflow. Don't compute the address of the object just
3306 before an array, as that's not portable. Use EMACS_INT, not
3307 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3308 * callint.c (Fcall_interactively):
3309 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3322 (casify_object): Avoid integer overflow when overallocating buffer.

3326 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3327 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3330 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3331 For CCL_MapSingle, check that content and value are in int range.

3334 (resolve_symbol_ccl_program): Check that vector header is in range.
3335 Always copy the vector, so that we can check its contents reliably
3336 now rather than having to recheck each instruction as it's being
3337 executed. Check that vector words fit in 'int'.
3338 (ccl_get_compiled_code, Fregister_ccl_program)
3339 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for

3345 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

3366 Don't rely on undefined behavior with signed left shift overflow.
3367 Don't assume unsigned int fits into fixnum, or that fixnum fits
3368 into unsigned int. Don't require max_code to be a valid fixnum;
3369 that's not true for gb10830 4-byte on a 32-bit host. Allow
3370 invalid_code to be a cons, for the same reason. Require code_offset
3371 to be a character. Avoid int overflow if max_char is close
3373 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3374 this is intended anyway and avoids some undefined behavior.
3375 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3376 INDEX_TO_CODE_POINT, as that's what it expects.
3377 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3378 * charset.h (DECODE_CHAR): Return int, not unsigned;
3379 this is what was intended anyway, and it avoids undefined behavior.
3380 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3381 integer-overflow issues.
3382 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3383 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3384 where the argument is EMACS_INT, and this behavior is not intended.

3996 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
3997 (handle_tool_bar_click):

3999 doesn't matter here.
4000 (get_next_display_element, next_element_from_display_vector):
4001 Use int, not EMACS_INT, when int is wide enough.

4041 * xterm.c (x_x_to_emacs_modifiers):
4042 Don't assume EMACS_INT overflows nicely into int.

4048 * xterm.h: Adjust decls to match defn changes elsewhere.
4049 (struct scroll_bar): Use struct vectorlike_header
4050 rather than rolling our own approximation.
4051 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4053 2012-05-25 Glenn Morris <rgm@gnu.org>
4055 * lisp.mk (lisp): Update for more files being compiled now.
4057 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
4059 * lread.c: Remove `read_pure' which makes no difference.
4060 (read_pure): Remove var.
4061 (unreadpure): Remove function.
4062 (readevalloop): Don't call read_list with -1 flag.

4077 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4080 This directory predates autoconf and is no longer needed nowadays.
4081 Move its few remaining bits of functionality to where they're needed.
4082 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

4092 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4093 (BITS_PER_EMACS_INT): New constants, replacing
4094 what used to be in config.h, but not useful in #if.
4095 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4096 define them any more.
4097 (VAL_MAX): New macro.
4099 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4100 BITS_PER_EMACS_INT, in #if.
4101 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4102 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4103 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4104 * s/ms-w32.h (DATA_START):
4105 Move here from removed file m/intel386.h.
4106 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4107 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4109 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4111 Assume C89 or later.

4121 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4122 * xterm.c (input_signal_count): Assume volatile works.
4124 2012-05-21 Ken Brown <kbrown@cornell.edu>
4126 * xgselect.c (xg_select): Fix first argument in call to 'select'
4129 2012-05-20 Ken Brown <kbrown@cornell.edu>
4131 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4132 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4134 2012-05-19 Ken Brown <kbrown@cornell.edu>
4136 * xfns.c (x_in_use): Remove `static' qualifier.
4137 * xterm.h (x_in_use): Declare.
4138 * xgselect.c: Include xterm.h.
4139 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4140 and `display_arg' (bug#9754).
4142 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4144 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4146 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4147 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4149 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4151 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4153 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4154 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4156 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4157 reference to image_cache->refcount.
4158 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4160 2012-05-17 Juri Linkov <juri@jurta.org>
4162 * search.c (Fword_search_regexp, Fword_search_backward)
4163 (Fword_search_forward, Fword_search_backward_lax)
4164 (Fword_search_forward_lax): Move functions to isearch.el
4165 (bug#10145, bug#11381).
4167 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4169 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4171 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4173 * lread.c (init_obarray): Declare Qt and Qnil as special.
4175 2012-05-14 Glenn Morris <rgm@gnu.org>
4177 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4178 Put "libexec" before "bin", for the sake of init_callproc_1.
4180 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4182 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4184 * unexaix.c: Port to more-recent AIX compilers.
4185 (report_error, report_error_1, make_hdr, copy_sym)
4186 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4187 Make arguments const char *, not char *, to avoid violations of C
4188 standard and to fix some AIX warnings reported by Gilles Pion.
4190 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4192 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4193 already have overlays loaded.
4194 (handle_single_display_spec): Before returning without displaying
4195 fringe bitmap, synchronize the bidi iterator with the main display
4196 iterator, by calling iterate_out_of_display_property.
4197 (iterate_out_of_display_property): Detect buffer iteration by
4198 testing that it->string is a Lisp string.
4199 (get_next_display_element): When the current object is exhausted,
4200 and there's something on it->stack, call set_iterator_to_next to
4201 proceed with what's on the stack, instead of returning zero.
4202 (set_iterator_to_next): If called at the end of a Lisp string,
4203 proceed to consider_string_end without incrementing string
4204 position. Don't increment display vector index past the end of
4205 the display vector. (Bug#11417)
4206 (pos_visible_p): Don't report a position visible when move_it_to
4207 stopped at the last line of window, which happens to be scanned
4208 backwards by the bidi iteration. (Bug#11464)
4210 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4212 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4213 and right-margin display specs even if the spec is invalid or we
4214 are on a TTY, and thus unable to display on the fringes.
4215 That's because the text with the property will not be displayed anyway,
4216 so we need to signal to the caller that this is a "replacing"
4217 display spec. This fixes display when the spec is invalid or we
4220 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4222 * unexaix.c (make_hdr): Fix typo in prototype.
4223 This bug broke the build on AIX. Problem reported by Gilles Pion.
4225 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4227 * keyboard.c (kbd_buffer_get_event): Read special events also in
4228 batch mode. (Bug#11415)
4230 2012-05-12 Glenn Morris <rgm@gnu.org>
4232 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4234 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4236 * lisp.mk (lisp): Add newcomment.elc.
4238 2012-05-12 Glenn Morris <rgm@gnu.org>
4240 * Makefile.in (MKDIR_P): New, set by configure.
4241 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4243 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4245 Remove unused function hourglass_started.
4246 * dispextern.h (hourglass_started):
4247 * w32fns.c (hourglass_started):
4248 * xdisp.c (hourglass_started): Remove.
4250 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4252 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4253 Update dependencies.
4255 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4257 * xgselect.c (xg_select): Put maxfds+1 into a var.
4258 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4260 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4262 2012-05-10 Dave Abrahams <dave@boostpro.com>
4264 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4265 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4267 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4269 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4270 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4271 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4272 Initialize xd_registered_buses.
4274 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4276 Untag more efficiently if USE_LSB_TAG.
4277 This is based on a proposal by YAMAMOTO Mitsuharu in
4278 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4279 For an admittedly artificial (nth 8000 longlist) benchmark on
4280 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4281 Emacs's overall text size by 1%.
4282 * lisp.h (XUNTAG): New macro.
4283 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4284 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4285 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4286 * eval.c (Fautoload):
4287 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4288 * frame.h (XFRAME): Use XUNTAG.
4290 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4291 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4292 Remove unportable assumptions about print widths of types like
4294 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4295 intptr_t when converting between pointer and integer, to avoid GCC
4296 warnings about wrong width.
4298 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4300 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4301 stack for each reader_thread, instead of defaulting to 8MB
4302 determined by the linker. This avoids failures in creating
4303 subprocesses on Windows 7, see the discussion in this thread:
4304 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4306 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4308 Fix up display of the *Minibuf-0* buffer in the mini window.
4309 * keyboard.c (read_char): Don't clear the echo area if there's no
4311 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4312 contents of *Minibuf-0*) if there's no message displayed in its stead.
4314 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4316 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4319 2012-05-06 Chong Yidong <cyd@gnu.org>
4321 * lisp.mk (lisp): Update.
4323 2012-05-05 Jim Meyering <meyering@redhat.com>
4325 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4327 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4329 * data.c (PUT_ERROR): New macro.
4330 (syms_of_data): Use it. Add new error type `user-error'.
4331 * undo.c (user_error): New function.
4332 (Fprimitive_undo): Use it.
4333 * print.c (print_error_message): Adjust print style for `user-error'.
4334 * keyboard.c (user_error): New function.
4335 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4337 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4339 Do not limit current-time-string to years 1000..9999.
4340 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4341 (Fcurrent_time_string): Support any year that is supported by the
4342 underlying localtime representation. Don't use asctime, as it
4343 has undefined behavior for years outside the range -999..9999.
4345 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4347 Fix race conditions involving setenv, gmtime, localtime, asctime.
4348 Without this fix, interrupts could mess up code that uses these
4349 nonreentrant functions, since setting TZ invalidates existing
4350 tm_zone or tzname values, and since most of these functions return
4351 pointers to static storage.
4352 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4353 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4354 Grow the critical sections to include not just invoking
4355 localtime/gmtime, but also accessing these functions' results
4356 including their tm_zone values if any, and any related TZ setting.
4357 (format_time_string): Last arg is now struct tm *, not struct tm **,
4358 so that the struct tm is saved in the critical section.
4359 All callers changed. Simplify allocation of initial buffer, partly
4360 motivated by the fact that memory allocation needs to be outside
4361 the critical section.
4363 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4365 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4366 with RESET_INTERVAL.
4368 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4369 Remove duplicated buffer name initialization.
4371 2012-05-02 Jim Meyering <jim@meyering.net>
4373 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4375 * xfns.c (x_window): Use xstrdup (Bug#11375).
4377 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4379 * xdisp.c (pos_visible_p): If already at a newline from the
4380 display string before the 'while' loop, don't walk back the glyphs
4381 from it3.glyph_row. Solves assertion violation when the display
4382 string begins with a newline (egg.el). (Bug#11367)
4384 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4386 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4389 2012-05-01 Glenn Morris <rgm@gnu.org>
4391 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4392 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4393 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4394 All were removed before 23.1.
4396 * dispnew.c: Remove HAVE_LIBNCURSES test;
4397 it is always true on relevant platforms.
4399 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4400 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4402 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4404 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4406 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4407 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4410 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4412 Do not avoid creating empty evaporating overlays (Bug#9642).
4413 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4414 That is, do not delete an evaporating overlay if it becomes
4415 empty after its bounds are adjusted to fit within its buffer.
4416 This fix caused other problems, and I'm reverting it until we get
4417 to the bottom of them.
4419 2012-04-27 Chong Yidong <cyd@gnu.org>
4421 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4425 * xdisp.c (pos_visible_p): If the window start position is beyond
4426 ZV, start the display from buffer beginning. Prevents assertion
4427 violation in init_iterator when the minibuffer window is scrolled
4430 * window.c (window_scroll_pixel_based): Likewise.
4432 2012-04-27 Chong Yidong <cyd@gnu.org>
4434 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4436 2012-04-27 Glenn Morris <rgm@gnu.org>
4438 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4439 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4441 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4443 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4444 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4446 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4448 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4449 display element, check also the underlying string or buffer
4450 character. (Bug#11341)
4452 * w32menu.c: Include w32heap.h.
4453 (add_menu_item): If the call to AppendMenuW (via
4454 unicode_append_menu) fails, disable Unicode menus only if we are
4455 running on Windows 9X/Me.
4457 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4459 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4462 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4464 * keyboard.c (read_char): Don't wipe echo area for select window
4465 events: These might get delayed via `mouse-autoselect-window'

4470 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4471 manipulation of :loaded-from data.
4473 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4475 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4476 now a cons (bug#11311).
4478 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4480 Do not create empty overlays with the evaporate property (Bug#9642).
4481 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4482 if it becomes empty after its bounds are adjusted to fit within
4483 its buffer. Without this fix, in a nonempty buffer (let ((o
4484 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4485 yields an empty overlay that has the evaporate property, which is
4486 not supposed to happen.
4488 Fix minor GTK3 problems found by static checking.
4489 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4626 (print_object): Check for cycles even when print-circle is nil and
4627 print-gensym is t, but only check print_depth if print-circle is nil.
4629 2012-04-20 Chong Yidong <cyd@gnu.org>
4631 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4632 set the status to "failed" and ensure that sentinel is run.

4687 New extern decls, to avoid calling undeclared functions.
4688 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4689 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4690 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

4707 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4708 Remove decls. This fixes an "It stinks!".
4710 * alloc.c (which_symbols): Fix alignment issue / type clash.
4712 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4714 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4760 2012-04-11 Daniel Colascione <dancol@dancol.org>
4762 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4763 against is gone. It's better to use vfork now so that when Cygwin
4764 gains a new, working vfork, we use it automatically (bug#10398).
4766 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4806 * gnutls.c (gnutls_log_function2i): Convenience log function.
4807 (emacs_gnutls_read): Use new log functions,
4808 `gnutls_handshakes_tried' process member, and

4821 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4823 * xdisp.c (set_cursor_from_row): If the display string appears in
4824 the buffer at position that is closer to point than the position
4825 after the display string, display the cursor on the first glyph of
4826 the display string. Fixes cursor display when a 'display' text
4827 property immediately follows invisible text. (Bug#11094)
4829 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4831 composite.c: use 'double' consistently
4832 * composite.c (get_composition_id): Use 'double' consistently
4833 instead of converting 'float' to 'double' and vice versa; this is
4834 easier to understand and avoids a GCC warning.
4836 2012-04-09 Glenn Morris <rgm@gnu.org>
4838 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4839 preparation for dumping it with emacs. (Bug#4789)

4863 objects, as mark_maybe_pointer will catch them otherwise.
4864 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4865 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4867 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4869 Fix typo that broke non-Windows builds.
4870 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

4883 [!WINDOWSNT]: New macros.
4884 (init_libxml2_functions, libxml2_loaded_p): New functions.
4885 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4886 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4887 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4888 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4890 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4891 Call init_libxml2_functions before calling libxml2 functions.
4892 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4894 * emacs.c: Don't include libxml/parser.h.
4895 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4896 xmlCleanupParser directly.
4898 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4900 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4902 * indent.c (Fvertical_motion): If there is a display string at
4903 point, use it.vpos to compute how many lines to backtrack after
4904 move_it_to point. (Bug#11133)
4906 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4908 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4909 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4910 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4911 macros related to unification of CJK characters. For the details,
4912 see the discussion following the message here:
4913 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4915 2012-04-04 Chong Yidong <cyd@gnu.org>
4917 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4919 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4921 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4922 instead of alloca. (Bug#11138)
4924 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4926 * w32menu.c (is_simple_dialog): Properly check lisp types.
4929 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4931 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4932 position we get to after a call to move_it_to fails the
4933 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4934 only if we wind up in a string from display property. (Bug#11063)
4936 * window.c (Fdelete_other_windows_internal): Invalidate the row
4937 and column information about mouse highlight, so that redisplay
4938 restores it after reallocating the glyph matrices. (Bug#7464)
4940 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4941 string comes from a `display' text property, use the buffer
4942 position of that property as if we actually saw that position in
4944 (move_it_by_lines): Remove the assertion that
4945 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4946 violated when there's a before-string at the beginning of a line.
4949 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4951 * xdisp.c (append_space_for_newline): If the default face was
4952 remapped, use the remapped face for the appended newline.
4953 (extend_face_to_end_of_line): Use the remapped default face for
4954 extending the face to the end of the line.
4955 (display_line): Call extend_face_to_end_of_line when the default
4956 face was remapped. (Bug#11068)
4958 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4960 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4962 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4964 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4966 2012-03-27 Glenn Morris <rgm@gnu.org>
4968 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4971 2012-03-26 Kenichi Handa <handa@m17n.org>
4973 * dispextern.h (struct glyph): Fix previous change. Change the
4974 bit length of glyphless.ch to 25 (Bug#11082).
4976 2012-03-26 Chong Yidong <cyd@gnu.org>
4978 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4979 (command_loop_1): Use it; inhibit selection update for
4980 handle-select-window too (Bug#8996).
4982 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4984 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4986 2012-03-25 Kenichi Handa <handa@m17n.org>
4988 * dispextern.h (struct glyph): Change the bit length of
4989 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4991 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4993 * s/ms-w32.h (tzname): Include time.h before redirecting to
4994 _tzname. Fixes the MSVC build. (Bug#9960)
4996 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4998 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5001 * xterm.c (XTread_socket): Only modify handling_signal if
5002 !SYNC_INPUT. (Bug#11080)
5004 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5006 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5007 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5008 when fetching a multibyte character consumes more bytes than
5009 CHAR_BYTES returns, due to unification of CJK characters in
5010 string_char. (Bug#11073)
5012 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5014 * process.c (wait_reading_process_output): Handle pty disconnect
5015 by refraining from sending oneself a SIGCHLD (bug#10933).
5017 2012-03-22 Chong Yidong <cyd@gnu.org>
5019 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5021 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

5026 2012-03-21 Chong Yidong <cyd@gnu.org>
5028 * xfaces.c (Vface_remapping_alist): Doc fix.
5030 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5032 * w32proc.c (Fw32_set_console_codepage)
5033 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5036 2012-03-20 Chong Yidong <cyd@gnu.org>
5038 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5039 to reflect default non-nil value of redisplay-dont-pause.
5041 2012-03-19 Kenichi Handa <handa@m17n.org>
5043 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5044 it fit in a valid range (Bug#11003).
5046 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5048 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5049 that is not from display property, accept the row as a "cursor
5050 row" if one of the string's character has a non-nil `cursor'
5051 property. Fixes cursor positioning when there are newlines in
5052 overlay strings, e.g. in icomplete.el. (Bug#11035)
5054 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5056 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5058 2012-03-12 Chong Yidong <cyd@gnu.org>
5060 * eval.c (inhibit_lisp_code): Rename from
5061 inhibit_window_configuration_change_hook; move from window.c.
5063 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5064 * window.c (run_window_configuration_change_hook)
5065 (syms_of_window): Callers changed.
5067 2012-03-11 Chong Yidong <cyd@gnu.org>

5076 is visible (Bug#10955).
5078 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5080 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5082 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5084 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5085 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5088 2012-03-03 Glenn Morris <rgm@gnu.org>
5090 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5092 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5094 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5095 position past the first glyph_row that ends at ZV. (Bug#10902)
5096 (redisplay_window, next_element_from_string): Fix typos in
5098 (redisplay_window): Pass to move_it_vertically the margin in
5099 pixels, not in screen lines.
5101 2012-03-02 Glenn Morris <rgm@gnu.org>
5103 * buffer.c (buffer-list-update-hook): Doc fix.
5105 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5107 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5108 push_it before setting up the iterator for the first overlay
5109 string, even if we have an empty string loaded.
5110 (next_overlay_string): If there's an empty string on the iterator
5111 stack, pop the stack. (Bug#10903)
5113 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5115 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5116 Suggested by Stefan Monnier in
5117 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5118 * alloc.c (widen_to_Lisp_Object): New static function.
5119 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5120 and widening them to Lisp_Objects. This would work even if
5121 USE_LSB_TAG is defined and wide integers are used, which might
5122 happen in a future version of Emacs.
5124 2012-02-25 Chong Yidong <cyd@gnu.org>
5126 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5129 * xselect.c (Fx_selection_exists_p): Doc fix.
5130 (x_clipboard_manager_save_all): Print an informative message
5131 before saving to clipboard manager.
5133 2012-02-24 Chong Yidong <cyd@gnu.org>
5135 * keyboard.c (process_special_events): Handle all X selection
5136 requests in kbd_buffer, not just the next one (Bug#8869).
5138 2012-02-23 Chong Yidong <cyd@gnu.org>
5140 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5141 call when setting menu-bar-lines and tool-bar-lines parameters.
5142 (unwind_create_frame_1): New helper function.
5144 * window.c (inhibit_window_configuration_change_hook): New var.
5145 (run_window_configuration_change_hook): Obey it.
5146 (syms_of_window): Initialize it.
5148 2012-02-22 Chong Yidong <cyd@gnu.org>
5150 * xterm.c (x_draw_image_relief): Add missing type check for
5151 Vtool_bar_button_margin (Bug#10743).
5153 2012-02-21 Chong Yidong <cyd@gnu.org>
5155 * fileio.c (Vfile_name_handler_alist): Doc fix.
5157 * buffer.c (Fget_file_buffer): Protect against invalid file
5158 handler return value.
5160 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5162 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5163 when computing $valmask.
5165 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5166 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5167 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5168 It's useless in that case, and it can cause problems on hosts
5169 that allocate halves of EMACS_INT values separately.
5170 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5171 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5172 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5173 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5174 it avoids undefined behavior on hosts where shifting right by more
5175 than the word width has undefined behavior.
5177 2012-02-19 Chong Yidong <cyd@gnu.org>
5179 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5180 (Funhandled_file_name_directory, Ffile_name_as_directory)
5181 (Fdirectory_file_name, Fexpand_file_name)
5182 (Fsubstitute_in_file_name): Protect against invalid file handler
5183 return values (Bug#10845).
5185 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5187 * .gdbinit (pitx): Fix incorrect references to fields of the
5190 2012-02-17 Chong Yidong <cyd@gnu.org>
5192 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5194 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5196 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5197 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5199 2012-02-15 Chong Yidong <cyd@gnu.org>
5201 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5202 marked as special. Also, starting docstrings with * is obsolete.
5204 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5206 * gnutls.c (emacs_gnutls_write): Fix last change.
5208 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5213 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5215 * keymap.c (Fsingle_key_description): Handle char ranges.
5217 2012-02-12 Chong Yidong <cyd@gnu.org>
5219 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5220 as that creates a dangerous corner case.
5222 * window.c (Fdelete_window_internal): Invalidate the mouse
5223 highlight (Bug#9904).
5225 2012-02-12 Glenn Morris <rgm@gnu.org>
5227 * xselect.c (Fx_own_selection_internal)
5228 (Fx_get_selection_internal, Fx_disown_selection_internal)
5229 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5230 * nsselect.m (Fx_own_selection_internal)
5231 (Fx_disown_selection_internal, Fx_selection_exists_p)
5232 (Fx_selection_owner_p, Fx_get_selection_internal):
5233 Sync docs and argument specs with the xselect.c versions.
5235 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5237 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5239 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5241 * w32select.c (Fx_selection_exists_p): Sync doc string and
5242 argument list with xselect.c. (Bug#10783)
5244 * w16select.c (Fx_selection_exists_p): Sync doc string and
5245 argument list with xselect.c. (Bug#10783)

5255 2012-02-07 Chong Yidong <cyd@gnu.org>
5257 * buffer.c (Fbuffer_local_variables)
5258 (buffer_lisp_local_variables): Handle unbound vars correctly;
5259 don't let Qunbound leak into Lisp.
5261 2012-02-07 Glenn Morris <rgm@gnu.org>
5263 * image.c (Fimagemagick_types): Doc fix.
5265 * image.c (imagemagick-render-type): Change it from a lisp object
5266 to an integer. Move the doc here from the lisp manual.

5269 2012-02-06 Chong Yidong <cyd@gnu.org>
5271 * doc.c (store_function_docstring): Avoid applying docstring of
5272 alias to base function (Bug#2603).
5274 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5276 * .gdbinit (pp1, pv1): Remove redundant defines.
5279 2012-02-04 Chong Yidong <cyd@gnu.org>
5281 * nsterm.m: Declare a global (Bug#10694).
5283 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5285 * w32.c (get_emacs_configuration_options):
5286 Include --enable-checking, if specified, in the return value.
5288 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5290 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5291 after rounding frame sizes. (Bug#9723)
5293 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5295 * keyboard.c (adjust_point_for_property): Don't position point
5296 before BEGV. (Bug#10696)
5298 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5300 Handle overflow when computing char display width (Bug#9496).
5301 * character.c (char_width): Return EMACS_INT, not int.
5302 (char_width, c_string_width): Check for overflow when
5303 computing the width; this is possible now that individual
5304 characters can have unbounded width. Problem introduced
5305 by merge from Emacs 23 on 2012-01-19.
5307 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5309 * dbusbind.c (Fdbus_register_method): Mention the return value

5322 2012-02-02 Kenichi Handa <handa@m17n.org>
5324 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5325 0, do not call append_composite_glyph.
5327 2012-02-02 Kenichi Handa <handa@m17n.org>
5329 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5331 (x_produce_glyphs): If the component of a composition is a null
5332 string, set it->pixel_width to 1 to avoid zero-width glyph.
5334 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5336 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5337 first 2 arguments are identical. This makes inserting large
5338 output from a subprocess an order of magnitude faster on
5339 MS-Windows, where all sbrk'ed memory is always contiguous.
5341 2012-01-31 Glenn Morris <rgm@gnu.org>

5869 * xdisp.c (redisplay_window): If cursor row is not fully visible
5870 after recentering, and scroll-conservatively is set to a large
5871 number, scroll window by a few more lines to make the cursor fully
5872 visible and out of scroll-margin. (Bug#10105)
5873 (start_display): Don't move to the next line if the display should
5874 start at a newline that is part of a display vector or an overlay

5958 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5959 is set, removing the need for VIRT_ADDRESS_VARIES.
5960 (PURE_P): Use a more-efficient implementation that needs just one
5961 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5962 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5963 to 4 (xorl, subq, cmpq, setbe).
5964 * alloc.c (pure): Always extern now, since that's the
5965 VIRT_ADDR_VARIES behavior.
5966 (PURE_POINTER_P): Use a single comparison, not two, for
5967 consistency with the new puresize.h.
5968 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5969 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

5975 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5976 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5977 behave as if the cursor position were at the window margin.
5979 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5980 and the cursor position is out of bounds, behave as if the cursor
5981 position were at the window margin. (Bug#10075)
5983 2011-11-18 Chong Yidong <cyd@gnu.org>
5985 * window.c (Fwindow_combination_limit): Make first argument

6007 compute_line_metrics.
6008 (compute_line_metrics): Call row_hash, instead of computing the
6011 * dispnew.c (verify_row_hash): Call row_hash for computing the
6012 hash code of a row, instead of duplicating code from xdisp.c.
6014 * dispextern.h (row_hash): Add prototype.
6016 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

6045 (Fset_window_configuration, save_window_save): Rename all
6046 occurrences of window_nest to window_combination_limit.
6048 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6050 * image.c (imagemagick_load_image): Fix typo.
6052 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6054 * xdisp.c (display_line): Move the call to
6055 highlight_trailing_whitespace before the call to
6056 compute_line_metrics, since the latter needs to see the final
6057 faces of all the glyphs to compute ROW's hash value.
6058 Fixes assertion violations in row_equal_p. (Bug#10035)
6060 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6062 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6067 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6068 with user-defined heap size. Bump the default size of the temacs
6069 heap to 27MB, to avoid memory warning when running temacs.
6070 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6072 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6119 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6121 Avoid some portability problems by eschewing 'extern inline' functions.
6122 The trivial performance wins aren't worth the portability hassles; see
6123 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6125 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6127 (window_box_right, window_box_right_offset): Undo previous change,
6128 by removing the "extern"s.
6129 * intervals.c (adjust_intervals_for_insertion)
6130 (adjust_intervals_for_deletion): Undo previous change,
6131 making these static again.
6132 (offset_intervals, temp_set_point_both, temp_set_point)
6133 (copy_intervals_to_string): No longer inline.
6134 * xdisp.c (window_text_bottom_y, window_box_width)

6200 (window_box_right, window_box_right_offset): Declare extern.
6201 Otherwise, these inline functions do not conform to C99 and
6202 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6203 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6204 * intervals.c (adjust_intervals_for_insertion)

6207 (static_offset_intervals): Remove.
6208 (offset_intervals): Rewrite using the old contents of
6209 static_offset_intervals. The old version didn't conform to C99
6210 because an extern inline function contained a reference to an
6211 identifier with static linkage.

6233 (Fwindow_vscroll): Doc fix.
6234 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6235 argument, since it makes no sense to pass a live window and for

6264 (unwind_create_frame): New function (Bug#9943).
6265 (Fx_create_frame): Restructure code to be more similar to the one in
6266 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6267 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6268 Move terminal->reference_count++ just before making the frame official

6333 2011-11-03 Eli Zaretskii <eliz@gnu.org>
6335 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
6337 * w32fns.c (unwind_create_frame): If needed, free the glyph
6338 matrices of the partially constructed frame. (Bug#9943)
6339 * xfns.c (unwind_create_frame): Likewise.
6341 2011-11-01 Eli Zaretskii <eliz@gnu.org>
6343 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
6344 Don't stop backward scan on the continuation glyph, even though
6345 its CHARPOS is positive.
6346 (mouse_face_from_buffer_pos, note_mouse_highlight):
6347 Rename cover_string to disp_string.
6349 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6351 * window.c (temp_output_buffer_show): Don't use
6352 Vtemp_buffer_show_specifiers.
6353 (Vtemp_buffer_show_specifiers): Remove unused variable.
6355 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6357 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
6358 past the beginning of the current glyph matrix.
6360 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
6362 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6363 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6364 HAVE_GTK3 (Bug#9869).
6366 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6367 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6369 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6371 * xterm.c: Declare x_handle_net_wm_state to return int.
6372 (handle_one_xevent): Check if we are iconified but don't have
6373 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6374 (get_current_wm_state): Return non-zero if not hidden,
6375 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6376 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6377 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6378 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6380 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6382 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6383 so that this new function doesn't get optimized away by a
6384 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6386 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6388 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6390 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6392 Fix the `xbytecode' command.
6393 * .gdbinit (xprintbytestr): New command.
6394 (xwhichsymbols): Rename from `which'; all callers changed.
6395 (xbytecode): Print the byte-code string as well.
6397 2011-10-29 Kim Storm <storm@cua.dk>
6399 * alloc.c (which_symbols): New function.
6401 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6403 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6406 2011-10-29 Glenn Morris <rgm@gnu.org>
6408 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6409 Not clear what it was for, and it causes various bugs. (Bug#9839)
6411 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6413 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6414 possible random value that matches one of those tested as
6415 condition to clear the mouse face.
6417 2011-10-28 Chong Yidong <cyd@gnu.org>
6419 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6421 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6423 * window.c (make_window): Initialize phys_cursor_on_p.
6425 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6427 * lisp.h (struct Lisp_Symbol): Update comments.
6429 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6431 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6433 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6435 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6436 <oslsachem@gmail.com> for helping to debug this.
6438 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6439 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6440 (g_b_init_get_glyph_outline_w): New static variables.
6441 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6442 (GetGlyphOutlineW_Proc): New typedefs.
6443 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6444 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6446 (w32font_open_internal, compute_metrics):
6447 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6448 instead of calling the "wide" APIs directly.
6450 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6452 * w32.h (syms_of_w32font): Add prototype.
6454 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6456 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6457 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6458 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6459 (Fmove_to_window_line): Doc fix.
6461 2011-10-27 Chong Yidong <cyd@gnu.org>
6463 * process.c (make_process): Set gnutls_state to NULL.
6465 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6466 non-NULL, regardless of GNUTLS_INITSTAGE.
6467 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6468 an error. Set process slots as soon as we allocate them.
6470 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6472 2011-10-27 Chong Yidong <cyd@gnu.org>
6474 * gnutls.c (emacs_gnutls_deinit): New function.

6476 (Fgnutls_deinit, Fgnutls_boot): Use it.
6478 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6479 (deactivate_process): Call emacs_gnutls_deinit.
6481 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6484 * w32.c (sys_rename, w32_delayed_load):
6485 * w32font.c (fill_in_logfont):
6486 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6488 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6490 * w32fns.c (w32_default_color_map): New function,
6491 extracted from Fw32_default_color_map.
6492 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6494 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6496 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6498 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6500 * keyboard.c (test_undefined): New function (bug#9751).
6501 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6503 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6505 * sysdep.c (init_sys_modes): Fix the check for the controlling
6506 terminal (Bug#6649).
6508 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6510 * dispextern.h (struct bidi_it): New member next_en_type.
6512 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6513 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6514 current character, check also for next_en_type being WEAK_EN.
6515 (bidi_resolve_weak): Don't enter the expensive loop if the current
6516 position is before next_en_pos. Record the bidi type of the first
6517 non-ET, non-BN character we find, in addition to its position.
6518 (bidi_level_of_next_char): Invalidate next_en_type when
6519 next_en_pos is over-stepped.
6521 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6523 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6524 * editfns.c: Rewrite current-time-zone so that it invokes
6525 the equivalent of (format-time-string "%Z") to get the time zone name.
6526 This fixes a bug when the time zone name contains characters that
6527 need converting from the system time locale to Emacs internal format.
6528 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6529 that patch fixed format-time-string to do the conversion, but
6530 I forgot to fix current-time-zone.
6531 (format_time_string): New function, containing most of
6532 what Fformat_time_string used to contain.
6533 (Fformat_time_string): Rewrite in terms of format_time_string.
6534 This doesn't change this function's behavior.
6535 (current-time-zone): Rewrite to use format_time_string.
6536 This fixes the bug reported by Michael Schierl in
6537 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6538 Jason Rumney's 2007-06-07 change worked around this bug, but
6540 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6542 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6544 * xdisp.c (start_display): If the character at POS is displayed
6545 via a display vector, reset IT->current.dpvec_index to zero.
6546 (try_window_reusing_current_matrix): If a line ends in a display
6547 vector or the next line starts in a display vector, continue
6548 redrawing the window even though the character position of
6549 start_row was reached.
6552 2011-10-18 Chong Yidong <cyd@gnu.org>
6554 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6555 with nobreak-char-display too.
6557 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6559 Fix part 3 of bug#9771.
6560 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6561 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6562 non-neutral characters if the current character is a paragraph
6563 separator (a.k.a. Newline). This avoids running the same
6564 expensive loop twice, once when we consume the preceding newline
6565 and the other time when the line actually needs to be displayed.
6566 Avoid the loop when we see neutrals on the base embedding level
6567 following a character whose directionality is the same as the
6568 paragraph's. This avoids running the expensive loop when a line
6569 ends in a long sequence of neutrals, like control characters.
6570 Add assertion against STRONG_AL type. Slightly rearrange code
6571 that determines the type of a neutral given the first non-neutral
6573 (bidi_level_of_next_char): Set next_en_pos to zero when
6574 invalidating its info.
6576 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6578 * xdisp.c (push_display_prop): Determine whether to record string
6579 or buffer position by IT->string, not by IT->method. Allow
6580 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6581 (move_it_vertically_backward): Don't look for character position
6582 immediately after the newline when in a continuation line.
6585 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6587 * window.c (coordinates_in_window): Rewrite and delabelize
6588 vertical border check. (Bug#5357) (Bug#9618)
6590 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6592 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6593 errors in XSetWindowBorder (bug#9310).
6595 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6597 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6598 avoid crash when xmalloc overrun checking is enabled.
6600 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6602 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6603 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6604 cursor motion with <left> and <right> arrow keys.
6606 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6607 some callers set that themselves.
6609 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6611 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6612 display string and the previous row comes from the same string and
6613 is empty. (Bug#9739) (Bug#9738)
6615 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6617 * doc.c (get_doc_string): Encode file name (bug#9735).
6619 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6621 * bidi.c (bidi_level_of_next_char):
6622 * xdisp.c (get_visually_first_element): Remove old incorrect
6623 comments regarding the Unicode Line Separator character.
6625 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6627 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6629 * alloc.c (Fgc_status): Do not access beyond zombies array
6630 boundary if nzombies > MAX_ZOMBIES.
6631 * alloc.c (dump_zombies): Add missing format specifier.
6633 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6635 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6636 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6638 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6639 Some packages use them to denote characters with modifiers.
6641 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6643 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6644 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6645 matching a pp-number. Rename parameter var to var1.
6647 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6649 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6651 2011-10-08 Glenn Morris <rgm@gnu.org>
6653 * callint.c (Fcall_interactively): Give a more explicit error for the
6654 'c' case with a non-character input. (Bug#8479)
6656 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6658 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6660 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6661 lines that are hscrolled on the left.
6663 * dispnew.c (buffer_posn_from_coords): Account for a possible
6664 presence of header-line. (Bug#4426)
6666 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6668 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6669 Don't advertise functionality which we discourage or doesn't work.
6671 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6673 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6674 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6675 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6676 this makes Emacs dump core during garbage collection on rare
6677 occasions. sizeof is obviously inferior to offsetof here, so
6678 stick with offsetof.
6679 (GC_POINTER_ALIGNMENT): New macro.
6680 (mark_memory): Omit 3rd (offset) arg; caller changed.
6681 Don't assume EMACS_INT alignment is the same as pointer alignment.
6683 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6685 * keyboard.c (read_key_sequence_remapped): New var.
6686 (read_key_sequence): Compute remapping in the right buffer.
6687 (command_loop_1): Use read_key_sequence's remapping directly.
6689 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6691 * dired.c (file_name_completion): Don't expand file name.
6692 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6693 before checking file name handler.
6695 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6696 they've been requested explicitly (bug#9591).
6698 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6700 * keymap.c (Fsingle_key_description): Use make_specified_string
6701 instead of build_string to build string from push_key_description.
6704 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6706 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6707 This fixes a Y2038 bug on 64-bit hosts.
6708 * buffer.c (reset_buffer):
6709 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6710 (Fclear_buffer_auto_save_failure):
6711 Use 0, not -1, to represent an unset failure time, since time_t
6712 might not be signed.
6714 Remove dependency on glibc malloc internals.
6715 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6716 Move back here from lisp.h, but with their new implementations.
6717 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6718 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6719 * charset.c (charset_table_init): New static var.
6720 (syms_of_charset): Use it instead of xmalloc. This removes a
6721 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6722 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6723 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6724 Move back to alloc.c.
6725 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6726 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6728 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6730 * nsterm.m (windowDidResize): Call x_set_window_size only when
6731 ns_in_resize is true. Otherwise set pixelwidth/height and
6732 call change_frame_size (Bug#9628).
6734 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6736 Port --enable-checking=all to Fedora 14 x86-64.
6737 * charset.c (syms_of_charset): Also account for glibc malloc's
6738 internal overhead when calculating the initial malloc maximum.
6740 Port --enable-checking=all to Fedora 14 x86.
6741 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6743 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6744 (overrun_check_realloc, overrun_check_free):
6745 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6746 That way, xmalloc returns a properly-aligned pointer even if
6747 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6748 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6749 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6750 into account when calculating the initial malloc maximum.
6751 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6752 Move here from alloc.c, so that charset.c can use it too.
6753 Properly align; the old code wasn't right for common 32-bit hosts
6754 when configured with --enable-checking=all.
6755 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6756 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6758 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6760 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6763 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6765 * xdisp.c (compute_display_string_end): If there's no display
6766 string at CHARPOS, return -1.
6768 * bidi.c (bidi_fetch_char): When compute_display_string_end
6769 returns a negative value, treat the character as a normal
6770 character not covered by a display string. (Bug#9624)
6772 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6774 * lread.c (Fread_from_string): Fix typo in docstring.
6776 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6778 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6779 newline, reseat the iterator instead of bidi-iterating there one
6780 character at a time. (Bug#9610)
6781 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6782 TO_CHARPOS if the bidi iterator is at base embedding level.
6784 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6786 * lread.c (readevalloop): Use correct code for NBSP.
6787 (read1): Likewise. (Bug#9608)
6789 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6791 * dbusbind.c (Fdbus_register_signal): When service is not
6792 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)

6813 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6815 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6816 Default value is now t. Doc fix.
6818 * indent.c (Fvertical_motion): Compute and apply the overshoot
6819 logic when moving up, not only when moving down. Fix the
6820 confusing name and values of the it_overshoot_expected variable;
6821 logic changes accordingly. (Bug#9254) (Bug#9549)
6823 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6824 CHARPOS is covered by a display string which includes newlines.
6825 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6826 is covered by a display string with embedded newlines.
6828 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6830 * dbusbind.c (Fdbus_register_signal): Add match rule to
6831 Vdbus_registered_objects_table. (Bug#9581)
6832 (Fdbus_register_method, Vdbus_registered_objects_table):
6835 2011-09-24 Jim Meyering <meyering@redhat.com>
6837 do not ignore write error for any output size
6838 The previous change was incomplete.
6839 While it makes emacs --batch detect the vast majority of stdout
6840 write failures, errors were still ignored whenever the output size is
6841 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6842 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6843 && echo FAIL: ignored write error
6844 FAIL: ignored write error
6845 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6846 && echo FAIL: ignored write error
6847 FAIL: ignored write error
6848 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6850 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6852 * emacs.c (Fkill_emacs): In noninteractive mode exit
6853 non-successfully if a write error occurred on stdout. (Bug#9574)
6855 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6857 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6860 * dispextern.h (struct it): Update the comment documenting what
6863 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6865 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6866 a display string, extend search for cursor position to end of row.
6867 (find_row_edges): If the row ends in a newline from a display
6868 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6869 Handle the case of a display string with multiple newlines.
6870 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6871 non-empty line. Fixes confusing cursor motion with arrow keys at
6872 the beginning of a line that starts with whitespace.
6874 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6876 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is

6881 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6884 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6886 * xdisp.c (display_line): Record maximum and minimum buffer
6887 positions even if no glyphs were produced (e.g., by a zero-width
6888 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6889 buffer positions that will be removed from the glyph row because
6891 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6892 column is beyond frame width: don't subtract 1 "pixel" when
6893 computing width of the stretch.
6894 (reseat_at_next_visible_line_start): Undo the change made on
6895 2011-09-17 that saved paragraph information and restored it after
6896 the call to `reseat'. (Bug#9545)
6898 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6900 * xdisp.c (expose_window): Save original value of phys_cursor_on_p

6915 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6916 initialized, to pacify gcc -Wuninitialized.
6918 * fileio.c: Report proper errno when syscall falls.
6919 (Finsert_file_contents): Save and restore errno,
6920 so that report_file_error outputs the correct diagnostic.
6921 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6923 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6925 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6927 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6929 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6930 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6932 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6934 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6935 about the current paragraph and restore it after the call to reseat.
6937 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6938 (bidi_find_paragraph_start): Search back for paragraph beginning
6939 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6940 (bidi_move_to_visually_next): Only trigger paragraph-related
6941 computations when the last character is a newline or at EOB, not
6942 just any NEUTRAL_B. (Bug#9470)
6944 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6945 truncated lines if point is covered by a display string. (Bug#9524)
6947 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6949 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6950 (cons_to_x_long): New function.
6951 (lisp_data_to_selection_data): Use it. Correct the test for
6952 short-versus-long data; it was negated. Break out of vector
6953 loop, for efficiency, when a long datum is discovered.
6955 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6957 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

6981 of TAB characters in a composition.
6983 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6985 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6986 This occurs when processing a multibyte format.
6987 Problem reported by Wolfgang Jenker.
6989 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6991 * xdisp.c (try_cursor_movement): Only check for exact match if
6992 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6994 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6996 Remove unused external symbols.
6997 * dispextern.h (calc_pixel_width_or_height): Remove decl.

7001 * w32term.c: Fix comment to match code.
7002 * xterm.c, xterm.h (x_catching_errors): Remove.
7004 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7006 * xselect.c: Use signed conversions more consistently (Bug#9498).
7007 (selection_data_to_lisp_data): Assume incoming selection data are
7008 signed integers, not unsigned. This is to be consistent with
7009 outgoing selection data, which was modified to use signed integers
7010 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7011 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7012 expects long, not unsigned long.
7014 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7016 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7017 computation of loop end. Reported by Johan Bockgård
7020 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7022 * frame.c (Fother_visible_frames_p): Function deleted.
7024 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7026 * indent.c (compute_motion): Process display vector front to back
7027 rather than the other way around. (Bug#2496)
7029 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7031 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7033 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7035 * minibuf.c (Fread_from_minibuffer): Doc fix.
7037 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7039 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7040 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7042 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7044 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7045 value for non-existent files.
7047 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7049 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7050 set its "size" to -1. This will set the modtime_size field of
7051 the corresponding buffer to -1, which is what
7052 verify-visited-file-modtime expects for files that do not exist.
7055 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7057 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7059 * lisp.h: ... from here. push_key_description is no longer
7060 defined in keyboard.c, so its declaration should not be in
7061 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7062 logically belongs with push_key_description.
7064 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7066 * buffer.h: Include <sys/types.h> instead of <time.h>.
7067 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7068 Problem reported by Herbert J. Skuhra.
7070 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7072 * xml.c (parse_region): Make the parsing work for
7073 non-comment-starting XML files again (bug#9144).
7075 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7077 * image.c (gif_load): Fix calculation of bottom and right corner.
7080 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7082 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7083 redisplay in small windows.
7085 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7087 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7089 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7091 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7092 Operate on live windows only.
7094 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7096 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7098 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7100 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7101 only under bidi iteration.
7103 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7105 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7109 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7110 Without this fix, the command to link temacs failed due to an
7111 undefined symbol __builtin_isnan. This is because
7112 /usr/include/iso/math_c99.h #defines isnan(x) to
7113 __builtin_isnan(x), but the bundled gcc, which identifies itself
7114 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7116 * floatfns.c (isnan): #undef, and then #define to a clone of
7118 (Fisnan): Always define, since it's always available now.
7119 (syms_of_floatfns): Always define isnan at the Lisp level.
7121 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7123 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7125 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7127 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7128 The previous code assumed that file offsets (off_t values) fit in
7129 EMACS_INT variables, which is not true on typical 32-bit hosts.
7130 The code messed up by falsely reporting buffer overflow in cases
7131 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7132 when "big" contains more than 2**29 bytes, even though this
7133 inserts just one byte and does not overflow the buffer.
7134 (Finsert_file_contents): Store file offsets as off_t
7135 values, not as EMACS_INT values. Check for overflow when
7136 converting between EMACS_INT and off_t. When checking for
7137 buffer overflow or for overlap, take the offsets into account.
7138 Don't use EMACS_INT for small values where int suffices.
7139 When checking for overlap, fix a typo: ZV was used where
7140 ZV_BYTE was intended.
7141 (Fwrite_region): Don't assume off_t fits into 'long'.
7142 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7144 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7146 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7148 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7150 sprintf-related integer and memory overflow issues (Bug#9412).
7152 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7153 (esprintf, exprintf, evxprintf): New functions.
7154 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7155 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7156 (modify_event_symbol): Do not assume that the length of
7157 name_alist_or_stem is safe to alloca and fits in int.
7158 (Fexecute_extended_command): Likewise for function name and binding.
7159 (Frecursion_depth): Wrap around reliably on integer overflow.
7160 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7161 since some callers pass EMACS_INT values.
7162 (Fsingle_key_description): Don't crash if symbol name contains more
7163 than MAX_ALLOCA bytes.
7164 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7165 (get_minibuffer): Arg is now EMACS_INT, not int.
7166 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7167 (esprintf, exprintf, evxprintf): New decls.
7168 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7170 * dbusbind.c (signature_cat): New function.
7171 (xd_signature, Fdbus_register_signal):
7172 Do not overrun buffer; instead, report string overflow.
7174 * dispnew.c (add_window_display_history): Don't overrun buffer.
7175 Truncate instead; this is OK since it's just a log.
7177 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7178 even if the time zone offset is outlandishly large.
7179 Don't mishandle offset == INT_MIN.
7181 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7182 when creating daemon; the previous buffer-overflow check was incorrect.
7184 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7185 which has the guts of the old verror function.
7187 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7188 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7190 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7191 (font_unparse_xlfd): Don't blindly alloca long strings.
7192 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7193 fits in int, when using sprintf. Use single snprintf to count
7194 length of string rather than counting it via multiple sprintfs;
7195 that's simpler and more reliable.
7196 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7197 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7198 sprintf, in case result does not fit in int.
7200 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7201 (fontset_from_font): Print it.
7203 * frame.c (tty_frame_count): Now printmax_t, not int.
7204 (make_terminal_frame, set_term_frame_name): Print it.
7205 (x_report_frame_params): In X, window IDs are unsigned long,
7206 not signed long, so print them as unsigned.
7207 (validate_x_resource_name): Check for implausibly long names,
7208 and don't assume name length fits in 'int'.
7209 (x_get_resource_string): Don't blindly alloca invocation name;
7210 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7213 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7214 (xg_check_special_colors, xg_set_geometry):
7215 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7217 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7218 Use esprintf, not sprintf, in case result does not fit in int.
7220 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7221 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7222 it as a large positive number.
7223 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7224 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7226 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7227 in case result does not fit in int.
7229 * print.c (float_to_string): Detect width overflow more reliably.
7230 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7231 buffer overrun. Don't assume list length fits in 'int'. Treat
7232 print length of 0 as 0, not as infinity; to be consistent with other
7233 uses of print length in this function. Don't overflow print length
7234 index. Don't assume hash table size fits in 'long', or that
7235 vectorlike size fits in 'unsigned long'.
7237 * process.c (make_process): Use printmax_t, not int, to format
7238 process-name gensyms.
7240 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7242 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7243 to avoid potential buffer overrun.
7245 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7246 if X resource line is longer than 512 bytes.
7248 * xfns.c (x_window): Make sprintf buffer a bit bigger
7249 to avoid potential buffer overrun.
7251 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7253 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7255 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7257 Integer overflow fixes for scrolling, etc.
7258 Without these, Emacs silently mishandles large integers sometimes.
7259 For example, "C-u 4294967297 M-x recenter" was treated as if
7260 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7262 * xdisp.c (try_window_id): Check Emacs fixnum range before
7263 converting to 'int'.
7265 * window.c (window_scroll_line_based, Frecenter):
7266 Check that an Emacs fixnum is in range before assigning it to 'int'.
7267 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7268 values converted from Emacs fixnums.
7269 (Frecenter): Don't wrap around a line count if it is out of 'int'
7270 range; instead, treat it as an extreme value.
7271 (Fset_window_configuration, compare_window_configurations):
7272 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7274 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7275 that can exceed INT_MAX. Check that EMACS_INT value is in range
7276 before assigning it to the (possibly-narrower) index.
7277 (match_limit): Don't assume that a fixnum can fit in 'int'.
7279 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7282 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7283 (Fvertical_motion): Don't wrap around LINES values that don't fit
7284 in 'int'. Instead, treat them as extreme values. This is good
7285 enough for windows, which can't have more than INT_MAX lines anyway.
7287 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7289 * Require libxml/parser.h to avoid compilation warning.
7291 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7293 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7294 since this reportedly can destroy thread storage.
7296 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7298 * syntax.c (find_defun_start): Update all cache variables if
7299 exiting early (Bug#9401).
7301 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7303 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7305 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7306 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7307 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7309 * term.c (tty_append_glyph): New function.
7310 (produce_stretch_glyph): Static function and its prototype deleted.
7312 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7315 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7317 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7318 when checking :margin (Bug#9390).
7319 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7320 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7321 so that the name doesn't mislead. All uses changed.
7323 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7325 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7328 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7330 * xdisp.c (move_it_to): Don't bail out early when reaching
7331 position beyond to_charpos, if we are scanning backwards.
7332 (move_it_vertically_backward): When DY == 0, make sure we get to
7333 the first character in the line after the newline.
7335 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7337 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7338 (ccl_driver): Do not generate an out-of-range pointer.
7339 (Fccl_execute_on_string): Remove unnecessary check for
7340 integer overflow, noted by Stefan Monnier in
7341 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7342 Remove a FIXME that didn't need fixing.
7343 Simplify the newly-introduced buffer reallocation code.
7345 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7347 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7349 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7351 Integer and memory overflow issues (Bug#9196).
7353 * doc.c (get_doc_string): Rework so that
7354 get_doc_string_buffer_size is the actual buffer size, rather than
7355 being 1 less than the actual buffer size; this makes xpalloc more
7358 * image.c (x_allocate_bitmap_record, cache_image):
7359 * xselect.c (Fx_register_dnd_atom):
7360 Simplify previous changes by using xpalloc.
7362 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7363 since either will do and ptrdiff_t is convenient with xpalloc.
7365 * charset.c (charset_table_size)
7366 (struct charset_sort_data.priority): Now ptrdiff_t.
7367 (charset_compare): Don't overflow if priorities differ greatly.
7368 (Fsort_charsets): Don't assume list length fits in int.
7369 Check for size-calculation overflow when allocating sort data.
7370 (syms_of_charset): Allocate an initial charset table that is
7371 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7373 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7375 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7376 The actual value is always <= INT_MAX, and leaving it unsigned made
7377 overflow checking harder.
7379 * dispextern.h (struct glyph_matrix.rows_allocated)
7380 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7381 with xpalloc. The values are still always <= INT_MAX.
7383 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7385 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7386 (SAFE_NALLOCA): New macro.
7388 * region-cache.c (struct boundary.pos, find_cache_boundary)
7389 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7390 (set_cache_region, invalidate_region_cache)
7391 (revalidate_region_cache, know_region_cache, region_cache_forward)
7392 (region_cache_backward, pp_cache):
7393 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7394 so that ptrdiff_t * can be passed to xpalloc.
7395 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7396 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7397 (pp_cache): Don't assume cache_len fits in int.
7398 * region-cache.h: Adjust extern decls to match.
7400 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7401 EMACS_INT, since either will do, for xpalloc.
7403 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7404 (xnmalloc, xnrealloc, xpalloc): New functions.
7406 * bidi.c (bidi_shelve_header_size): New constant.
7407 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7408 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7410 * bidi.c (bidi_cache_shrink):
7411 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7413 Don't update size of array until after memory allocation succeeds,
7414 because xmalloc/xrealloc may not return.
7415 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7416 now that we have proper integer overflow checking.
7417 (record_overlay_string, overlay_strings): Catch overflows when
7418 calculating size of overlay_str_buf.
7420 * callproc.c (Fcall_process): Check for size overflow when
7421 calculating size of args2.
7422 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7423 Normally we prefer signed values, but sticking with ptrdiff_t would
7424 require adding more-complicated checks.
7426 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7427 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7428 Redo buffer-overflow calculations to avoid integer overflow.
7429 Add a FIXME comment where memory seems to be over-allocated.
7431 * character.c (Fstring): Check for size-calculation overflow.
7433 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7434 unnecessary integer overflow. Check for size overflow.
7435 (encode_coding_object): Don't update size until xmalloc succeeds.
7437 * composite.c (get_composition_id): Check for overflow in glyph
7438 length calculations.
7440 Integer and memory overflow fixes for display code.

7456 (get_doc_string): Check for size calculation overflow.
7457 Don't update size until allocation succeeds.
7458 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7459 EMACS_INT, where ptrdiff_t will do.
7460 (Fsubstitute_command_keys): Check for string overflow.
7462 * editfns.c (set_time_zone_rule): Don't assume environment length
7464 (message_length): Now ptrdiff_t, not int.
7465 (Fmessage_box): Don't update size until allocation succeeds.
7466 Don't assume message length fits in int.
7467 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7469 * emacs.c (main): Do not reallocate argv, since there is a null at
7470 the end that can be overwritten, and this way there's no need to
7471 worry about size-calculation overflow.
7472 (sort_args): Check for size-calculation overflow.
7474 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7476 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7478 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7479 (x_set_scroll_bar_width, x_figure_window_size):
7480 Check for integer overflow.
7481 (x_set_alpha): Do not assume XINT fits in int.
7483 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7484 This is for the members text_lines, text_cols, total_lines, total_cols,
7485 where the system imposes an 'int' limit.
7487 * fringe.c (Fdefine_fringe_bitmap):
7488 Don't update size until alloc works.
7490 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7491 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7493 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7494 Check for size-calculation overflow.
7495 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7496 do, as we prefer signed integers.
7497 (id_to_widget.max_size, id_to_widget.used)
7498 (xg_store_widget_in_map, xg_remove_widget_from_map)
7499 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7500 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7501 Use and return ptrdiff_t, not int.
7502 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7503 * gtkutil.h: Change prototypes to match the above.
7505 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7506 are duplicate now that they've been promoted to lisp.h.
7507 (x_allocate_bitmap_record, x_alloc_image_color)
7508 (make_image_cache, cache_image, xpm_load):
7509 Don't update size until alloc is done.

7519 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7520 Use ptrdiff_t, not int, to count maps.

7537 Now ptrdiff_t, not int.
7538 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

7550 (Fset_match_data): Don't assume list lengths fit in 'int'.
7552 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7553 for command line length. Do not attempt to address one before the

7559 (encode_terminal_code, calculate_costs): Check for size
7560 calculation overflow.

7584 Check for size calculation overflow.
7585 (cache_face): Treat size calculation overflows as if they were

7588 * xfns.c (x_encode_text, x_set_name_internal)
7589 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7590 sizes, since they can exceed INT_MAX in size. Check for size

7601 (X_LONG_MIN): New macros.
7602 Use them to make the following changes clearer.
7603 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7604 This change doesn't affect the value now, but it may help remind
7605 future maintainers not to raise the value too much later.
7606 (SELECTION_QUANTUM): Remove, replacing with ...
7607 (selection_quantum): ... new function, which avoids overflow.
7609 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

7618 Redo calculations to avoid overflow.
7619 (x_reply_selection_request): When sending hint, ceiling it at
7620 X_LONG_MAX rather than relying on wraparound overflow to send

7623 (lisp_data_to_selection_data, x_property_data_to_lisp):
7624 Check for size-calculation overflow.

7627 Don't store size until memory allocation succeeds.
7628 (x_get_window_property): Plug memory leak on memory exhaustion.
7629 Don't double-block input; malloc is safe here. Don't assume 2**34
7630 - 4 fits in unsigned long. Add an xassert to check
7631 XGetWindowProperty overflow. Be more careful about overflow
7632 calculations, and distinguish size from memory overflow better.
7633 (receive_incremental_selection): When tracing, don't assume
7634 unsigned int is less than INT_MAX.
7635 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7636 harmful) conversions of unsigned short to int.
7637 (lisp_data_to_selection_data): Don't assume that integers
7638 in the range -65535 through -1 fit in an X unsigned short.
7639 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7640 result parameters unless successful. Rely on cons_to_unsigned
7641 to report problems with elements; the old code wasn't right anyway.
7642 (x_check_property_data): Check for int overflow; we cannot use
7643 a wider type due to X limits.
7644 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7676 * lisp.h (hash_lookup, hash_put):
7677 * minibuf.c (Ftest_completion):
7678 Use ptrdiff_t for hash table indexes, not int (which is too
7679 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7680 32-bit --with-wide-int hosts).
7682 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7683 Add a FIXME comment about memory leaks.

7688 * character.h (CHAR_WIDTH):
7689 * indent.c (MULTIBYTE_BYTES_WIDTH):
7690 Use sanitize_char_width to avoid undefined and/or bad behavior
7691 with outlandish widths.
7692 * character.h (sanitize_tab_width): Rename from sanitize_width,
7693 now that we have two such functions. All uses changed.
7694 (sanitize_char_width): New inline function.
7696 Don't assume that tab-width fits in int.

7718 (make_lispy_movement): Use same integer type in forward decl
7719 that is used in the definition.
7720 (read_key_sequence, keyremap_step):
7721 Change bufsize argument back to int, undoing my 2011-03-30 change.
7722 We prefer signed types, and int is wide enough here.
7723 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7724 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7725 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7726 length, not size_t. Use ptrdiff_t for index, not int.
7727 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7728 possibility of integer overflow.
7730 Overflow, signedness and related fixes for images.

7756 Prefer int to unsigned where either will do.
7757 (tiff_handler): New function, combining the cores of the
7758 old tiff_error_handler and tiff_warning_handler.
7759 This function is rewritten to use vsnprintf and thereby avoid
7760 stack buffer overflows. It uses only the features of vsnprintf
7761 that are common to both POSIX and native Microsoft.
7762 (tiff_error_handler, tiff_warning_handler): Use it.
7763 (tiff_load, gif_load, imagemagick_load_image):

7767 the integer types that MagickCropImage accepts. Don't assume
7768 Vimagemagick_render_type has a nonnegative value. Don't assume
7769 size_t fits in 'long'.
7770 (gs_load): Use printmax_t to print the widest integers possible.

7784 (handle_single_display_spec): If the display spec is of the form
7785 `(space ...)', and specifies display in the text area, return 2
7787 (try_cursor_movement): Check for the need to scroll more
7788 accurately, and prefer exact match for point under bidi.
7789 Don't advance `row' beyond the last row of the window.
7791 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7792 into disp_prop; all users changed.

7807 buffers, return left-to-right.
7808 (set_cursor_from_row): Consider candidate row a win if its glyph
7809 represents a newline and point is on that newline. Fixes cursor
7810 positioning on the newline at EOL of R2L text within L2R
7811 paragraph, and vice versa.
7812 (try_cursor_movement): Check continued rows, in addition to
7813 continuation rows. Fixes unwarranted scroll when point enters a
7814 continued line of R2L text within an L2R paragraph, or vice versa.
7815 (cursor_row_p): Consider the case of point being equal to
7816 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7817 from the end of a short line to the beginning of a continued line
7818 of R2L text within L2R paragraph.
7819 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7820 composed characters.
7822 * bidi.c (bidi_check_type): Use xassert.

7837 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7838 extra slot even if the purpose is char-code-property-table.
7840 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7842 * xdisp.c (redisplay_window): When computing centering_position,
7843 account for the height of the header line. (Bug#8874)
7845 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7846 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7847 candidate is selected by the mouse, and that candidate has a
7848 composed character under the mouse.
7850 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7851 coordinates reported by pos-visible-in-window-p for a composed
7852 character in column zero.

7861 consider it a hit if to_charpos is anywhere in the range of the
7862 composed buffer positions.
7864 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7866 * image.c (gif_load): Don't assume that each subimage has the same
7867 dimensions as the base image. Handle disposal method that is
7868 "undefined" by the gif spec (Bug#9335).
7870 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

7877 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7878 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7879 from an Org mode buffer to a Speedbar frame.
7881 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7882 a composition, take its buffer position from IT->cmp_it.charpos.
7883 Fixes cursor positioning at the beginning of a line that begins
7884 with a composed character.
7886 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7888 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7889 character bidirectional type, use STRONG_L instead. Fixes crashes
7890 in a buffer produced by `describe-categories'.
7892 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7893 members before the level stack, so they would be saved and
7894 restored when copying iterator state. Fixes incorrect reordering
7895 around TABs covered by display properties.

8030 buffer/string position, to be restored by pop_it. Fix flags in
8031 the iterator structure wrt the object coming from a display
8032 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8033 properties. (Bug#9284)

8092 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8093 amount allocated this far in `bidi_cache_total_alloc'.
8094 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if

8209 setting frame foreground color (Bug#9175).
8210 (x_set_background_color): Likewise.
8212 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8213 contents (Bug#9176).
8214 (EmacsTooltip -init): Remove bezels and add shadows to
8217 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8218 or scroll bar (Bug#8470).
8220 * nsfont.m (nsfont_open): Remove assignment to voffset and
8221 unnecessary vars hshink, expand, hd, full_height, min_height.
8222 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8224 * nsterm.h (nsfont_info): Remove voffset field.
8226 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8228 Implement strike-through and overline on NextStep (Bug#8863).
8230 * nsfont.m (nsfont_open): Use underline position provided by font,
8231 instead of hard-coded value of 2.
8232 (nsfont_draw): Call ns_draw_text_decoration instead.
8234 * nsterm.h: Add declaration for ns_draw_text_decoration.
8236 * nsterm.m (ns_draw_text_decoration): New function for drawing
8237 underline, overline, and strike-through.
8238 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8239 ns_draw_text_decoration. Change treatment of cursor drawing to
8240 accommodate underlining, etc.
8242 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8244 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8247 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8249 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8250 Without this fix, if a signal arrives just after memory fills up,
8251 'malloc' might be invoked reentrantly.
8253 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8254 In other words, assume that every image size is allowed, on non-X
8255 hosts. This assumption is probably wrong, but it lets Emacs compile.
8257 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8259 * regex.c (re_iswctype): Convert return values to boolean.
8261 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8263 * xdisp.c (compute_display_string_pos): Don't use cached display
8264 string position if the buffer had its restriction changed.
8267 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8269 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8271 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8273 Integer signedness and overflow and related fixes. (Bug#9079)
8275 * bidi.c: Integer size and overflow fixes.
8276 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8277 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8278 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8279 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8280 (bidi_find_other_level_edge):
8281 Use ptrdiff_t instead of EMACS_INT where either will do.
8282 This works better on 32-bit hosts configured --with-wide-int.
8283 (bidi_cache_ensure_space): Check for size-calculation overflow.
8284 Use % rather than repeated addition, for better worst-case speed.
8285 Don't set bidi_cache_size until after xrealloc returns, because it
8287 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8288 (bidi_cache_ensure_space): Also check that the bidi cache size
8289 does not exceed that of the largest Lisp string or buffer. See Eli
8290 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8292 * alloc.c (__malloc_size_t): Remove.
8293 All uses replaced by size_t. See Andreas Schwab's note
8294 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8296 * image.c: Improve checking for integer overflow.
8297 (check_image_size): Assume that f is nonnull, since
8298 it is always nonnull in practice. This is one less thing to
8299 worry about when checking for integer overflow later.
8300 (x_check_image_size): New function, which checks for integer
8301 overflow issues inside X.
8302 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8303 This removes the need for a memory_full check.
8304 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8305 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8306 (xbm_read_bitmap_data): Change locals back to 'int', since
8307 their values must fit in 'int'.
8308 (xpm_load_image, png_load, tiff_load):
8309 Invoke x_create_x_image_and_pixmap earlier,
8310 to avoid much needless work if the image is too large.
8311 (tiff_load): Treat overly large images as if
8312 x_create_x_image_and_pixmap failed, not as malloc failures.
8313 (gs_load): Use x_check_image_size.
8315 * gtkutil.c: Omit integer casts.
8316 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8317 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8319 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8321 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8322 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8323 would wrongly return t on a 64-bit host.
8325 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8326 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8327 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8328 and therefore cause GCC to emit a bogus diagnostic in some cases.
8330 * image.c: Integer signedness and overflow and related fixes.
8331 This is not an exhaustive set of fixes, but it's time to
8332 record what I've got.
8333 (lookup_pixel_color, check_image_size): Remove redundant decls.
8334 (check_image_size): Don't assume that arbitrary EMACS_INT values
8335 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8336 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8337 (tiff_load, imagemagick_load_image):
8338 Check for overflow in size calculations.
8339 (x_create_x_image_and_pixmap): Remove unnecessary test for
8340 xmalloc returning NULL; that can't happen.
8341 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8342 (xpm_color_bucket): Use better integer hashing function.
8343 (xpm_cache_color): Don't possibly over-allocate memory.
8344 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8345 (gif_memory_source):
8346 Use ptrdiff_t, not int or size_t, to record sizes.
8347 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8348 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8349 either works, as we prefer signed integers.
8350 (tiff_read_from_memory, tiff_write_from_memory):
8351 Return tsize_t, not size_t, since that's what the TIFF API wants.
8352 (tiff_read_from_memory): Don't fail simply because the read would
8353 go past EOF; instead, return a short read.
8354 (tiff_load): Omit no-longer-needed casts.
8355 (Fimagemagick_types): Don't assume size fits into 'int'.
8357 Improve hashing quality when configured --with-wide-int.
8358 * fns.c (hash_string): New function, taken from sxhash_string.
8359 Do not discard information about ASCII character case; this
8360 discarding is no longer needed.
8361 (sxhash-string): Use it. Change sig to match it. Caller changed.
8362 * lisp.h: Declare it.
8363 * lread.c (hash_string): Remove, since we now use fns.c's version.
8364 The fns.c version returns a wider integer if --with-wide-int is
8365 specified, so this should help the quality of the hashing a bit.
8367 * emacs.c: Integer overflow minor fix.
8368 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8369 Define only if GNU_LINUX.
8370 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8372 * dispnew.c: Integer signedness and overflow fixes.
8373 Remove unnecessary forward decls, that were a maintenance hassle.
8374 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8376 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8377 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8378 (prepare_desired_row, line_draw_cost):
8379 Use int, not unsigned, where either works.
8380 (save_current_matrix, restore_current_matrix):
8381 Use ptrdiff_t, not size_t, where either works.
8382 (init_display): Check for overflow more accurately, and without
8383 relying on undefined behavior.
8385 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8386 Remove, replacing with the new symbols in lisp.h. All uses changed.
8387 * fileio.c (make_temp_name):
8388 * filelock.c (lock_file_1, lock_file):
8389 * xdisp.c (message_dolog):
8390 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8391 Use pMd etc. instead.
8392 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8393 replacing the pWIDE etc. symbols removed from editfns.c.
8395 * keyboard.h (num_input_events): Now uintmax_t.
8396 This is (very slightly) less likely to mess up due to wraparound.
8399 * buffer.c: Integer signedness fixes.
8400 (alloc_buffer_text, enlarge_buffer_text):
8401 Use ptrdiff_t rather than size_t when either will do, as we prefer
8404 * alloc.c: Integer signedness and overflow fixes.
8405 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8406 (__malloc_size_t): Default to size_t, not to int.
8407 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8408 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8409 Prefer ptrdiff_t to size_t when either would do, as we prefer
8411 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8412 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8413 Now const. Initialize with values that are in range even if char
8415 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8416 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8417 These functions do the right thing with sizes > 2**32.
8418 (check_depth): Now ptrdiff_t, not int.
8419 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8420 Adjust to new way of storing sizes. Check for size overflow bugs
8422 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8423 slightly wrong anyway, as it missed one instance of
8424 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8425 (refill_memory_reserve): Omit needless cast to size_t.
8426 (mark_object_loop_halt): Mark as externally visible.
8428 * xselect.c: Integer signedness and overflow fixes.
8429 (Fx_register_dnd_atom, x_handle_dnd_message):
8430 Use ptrdiff_t, not size_t, since we prefer signed.
8431 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8432 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8433 x_dnd_atoms_size and x_dnd_atoms_length.
8435 * doprnt.c: Prefer signed to unsigned when either works.
8437 * doprnt.c (doprnt):
8439 * xdisp.c (vmessage):
8440 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8441 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8442 prefer signed arithmetic to avoid comparison confusion.
8443 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8444 but is a bit tricky.
8446 Assume freestanding C89 headers, string.h, stdlib.h.
8447 * data.c, doprnt.c, floatfns.c, print.c:
8448 Include float.h unconditionally.
8449 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8450 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8451 * regex.c: Likewise for stddef.h, string.h.
8452 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8453 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8454 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8455 (STDC_HEADERS): Remove obsolete defines.
8456 * sysdep.c: Include limits.h unconditionally.
8458 Assume support for memcmp, memcpy, memmove, memset.
8459 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8460 * regex.c (memcmp, memcpy):
8461 Remove; we assume C89 now.
8463 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8464 (__malloc_safe_bcopy): Remove; no longer needed.
8466 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8467 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8468 well either way, and we prefer signed to unsigned.
8470 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8472 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8473 closes the connection while we're reading (bug#9182).
8475 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8477 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8478 are specified (Bug#9168).
8480 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8482 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8483 Found by GCC static checking and --with-wide-int on a 32-bit host.
8485 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8487 * xdisp.c (compute_display_string_pos): Fix logic of caching
8488 previous display string position. Initialize cached_prev_pos to
8489 -1. Fixes slow-down at the beginning of a buffer.
8491 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8493 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8494 for attrs[LFACE_FONTSET_INDEX].
8496 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8498 * xml.c (parse_region): Remove unused local
8499 that was recently introduced.
8501 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8503 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8504 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8506 * xdisp.c (move_it_in_display_line_to): Record the best matching
8507 position for TO_CHARPOS while scanning the line, and restore it on
8508 exit if none of the characters scanned was an exact match.
8509 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8510 when exact match is impossible due to invisible text, and the
8511 lines are truncated.
8513 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8515 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8518 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8520 Fix a significant slow-down of cursor motion with C-n, C-p,
8521 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8522 auto-repeat under bidi redisplay in fontified buffers.
8523 * xdisp.c (compute_stop_pos_backwards): New function.
8524 (next_element_from_buffer): Call compute_stop_pos_backwards to
8525 find a suitable prev_stop when we find ourselves before
8527 (reseat): Don't look for prev_stop, as that could mean a very long
8529 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8530 <cached_disp_overlay_modiff>: Cache for last found display string
8532 (compute_display_string_pos): Return the cached position if asked
8533 about the same buffer in the same area of character positions, and
8534 the buffer wasn't changed since the time the display string
8535 position was cached.
8537 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8539 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8540 is an integer, which is important for empty lines. (Bug#9149)
8542 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8544 * frame.c (Fmodify_frame_parameters): In tty case, update the
8545 default face if necessary (Bug#4238).
8547 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8549 * editfns.c (Fstring_to_char): No need to explain what a character
8550 is in the docstring (Bug#6576).
8552 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8554 * xml.c (parse_region): Make sure we always return a tree.
8556 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8558 * xml.c (parse_region): If a document contains only comments,
8561 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8563 * xml.c (make_dom): Return comments, too.
8565 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8568 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8569 and the surrounding thread.
8570 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8571 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8572 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8574 * s/openbsd.h (BROKEN_SIGIO): Define.
8575 * unexelf.c (unexec) [__OpenBSD__]:
8576 Don't update the .mdebug section of the Alpha COFF symbol table.
8578 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8580 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8583 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8585 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8586 This fixes some race conditions on the permissions of any newly
8589 * alloc.c (valid_pointer_p): Use pipe, not open.
8590 This fixes some permissions issues when debugging.
8592 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8593 If fchown fails to set both uid and gid, try to set just gid,
8594 as that is sometimes allowed. Adjust the file's mode to eliminate
8595 setuid or setgid bits that are inappropriate if fchown fails.
8597 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8599 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8600 to compare Lisp_Objects.
8601 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8602 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8603 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8605 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8607 * lread.c (read_integer): Unread even EOF character.
8608 (read1): Likewise. Properly record start position of symbol.
8610 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8611 symbol character follows.
8613 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8615 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8616 This works around a problem with the previous change to Fcopy_file.
8617 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8618 and without this change, GCC might complain about discarding
8619 fchown's return value.
8621 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8623 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8625 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8627 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8629 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8631 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8632 it's used from the C level.
8634 * process.c: Use the same condition for POLL_FOR_INPUT in both
8635 keyboard.c and process.c (bug#1858).
8637 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8639 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8640 (Fgnutls_boot): Use it.
8642 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8644 * doc.c (Fsubstitute_command_keys): Revert last change.
8646 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8648 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8649 quotes the next character, and doesn't affect other longer
8650 sequences (bug#8935).
8652 * lread.c (syms_of_lread): Clarify that is isn't only
8653 `eval-buffer' and `eval-defun' that's affected by
8654 `lexical-binding' (bug#8460).
8656 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8658 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8659 bidi redisplay when a line includes both an image and is truncated.
8661 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8663 Fix minor problems found by static checking.
8664 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8665 (elsz): Now a signed constant, not a size_t var. We prefer signed
8666 types to unsigned, to avoid integer comparison confusion. Without
8667 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8668 "cannot optimize loop, the loop counter may overflow", a symptom

9195 (clone_per_buffer_values): Don't assume that

9236 Random fixes. E.g., (random) never returned negative values.
9237 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9238 subseconds part to the entropy, as that's a bit more random.
9239 Prefer signed to unsigned, since the signedness doesn't matter and
9240 in general we prefer signed. When given a limit, use a
9241 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9242 latter isn't right if USE_2_TAGS_FOR_INTS.
9243 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9244 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9257 This is more efficient than Ffile_directory_p and avoids a minor race.
9259 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9261 * buffer.c (Foverlay_put): Say what the return value is
9264 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9265 is a directory before asking whether to use the file name
9267 (barf_or_query_if_file_exists): Make the "File is a directory"
9268 error be more correct.
9270 * fns.c (Frequire): Remove the mention of the .gz files, since
9271 that's installation-specific, but keep the mention of
9272 `get-load-suffixes'.
9274 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9276 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9287 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9288 Also (re)move comments that are misplaced or no longer relevant.

9389 * eval.c (struct backtrace): Simplify and port the data structure.
9390 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9391 signed bit field, as this assumption is not portable and it makes
9392 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9393 "char debug_on_exit : 1" as this is not portable either; instead,
9394 use the portable "unsigned int debug_on_exit : 1". Remove unused
9395 member evalargs. Remove obsolete comments about cc bombing out.

9587 (read_escape): Avoid int overflow.
9588 (Fload, openp, read_buffer_size, read1)
9589 (substitute_object_recurse, read_vector, read_list, map_obarray):
9590 Use ptrdiff_t, not int, for sizes.
9591 (read1): Use EMACS_INT, not int, for sizes.
9592 Check for size overflow.
9594 * image.c (cache_image): Check for size arithmetic overflow.
9596 * lread.c: Integer overflow issues.
9597 (saved_doc_string_size, saved_doc_string_length)
9598 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9599 Now ptrdiff_t, not int.
9600 (read1): Don't assume doc string length fits in int. Check for
9601 out-of-range doc string lengths.
9602 (read_list): Don't assume file position fits in int.
9603 (read_escape): Check for hex character overflow.
9605 2011-06-22 Leo Liu <sdl.web@gmail.com>
9607 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9608 Move to minibuffer.el.
9610 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9612 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9613 The following patches are for when GLYPH_DEBUG && !XASSERT.
9614 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9615 * dispnew.c (flush_stdout):
9616 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9617 Mark as externally visible.
9618 * dispnew.c (check_window_matrix_pointers): Now static.
9619 * dispnew.c (window_to_frame_vpos):
9620 * xfns.c (unwind_create_frame):
9621 * xterm.c (x_check_font): Remove unused local.
9622 * scroll.c (CHECK_BOUNDS):
9623 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9624 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9625 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9626 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9627 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9629 (debug_method_add): Use va_list and vsprintf rather than relying
9630 on undefined behavior with wrong number of arguments.
9631 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9632 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9633 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9634 since we're not interested in debugging glyphs with old libraries.
9635 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9636 GCC 4.6.0's static checking.
9638 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9640 Integer overflow and signedness fixes (Bug#8873).
9641 A few related buffer overrun fixes, too.

9645 * dispextern.h (struct face.stipple):
9646 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9647 (x_bitmap_mask, x_allocate_bitmap_record)
9648 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9649 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9650 (x_create_bitmap_from_xpm_data):
9651 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9652 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9654 * xfaces.c (load_pixmap):
9655 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9656 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9657 (.bitmaps_last, struct x_output.icon_bitmap):
9658 Use ptrdiff_t, not int, for bitmap indexes.
9659 (x_allocate_bitmap_record): Check for size overflow.
9660 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9662 Use ptrdiff_t, not int, for overlay counts.
9663 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9664 * editfns.c (overlays_around, get_pos_property):
9665 * textprop.c (get_char_property_and_overlay):
9666 * xdisp.c (next_overlay_change, note_mouse_highlight):
9667 * xfaces.c (face_at_buffer_position):
9668 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9669 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9670 (Fnext_overlay_change, Fprevious_overlay_change)
9671 (mouse_face_overlay_overlaps, Foverlays_in):
9672 Use ptrdiff_t, not int, for sizes.
9673 (overlays_at, overlays_in): Check for size-calculation overflow.
9675 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9677 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9678 (x_session_initialize): Do not assume string length fits in int.
9680 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9681 This is unlikely, but can occur if DPI is outlandish.
9683 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9684 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9686 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9687 * xrdb.c (magic_file_p, search_magic_path):
9688 Omit last arg SUFFIX; it was always 0. All callers changed.
9689 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9691 * xfont.c (xfont_match): Avoid need for strlen.
9693 * xfns.c: Don't assume strlen fits in int.
9694 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9696 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9697 not unsigned long, as we prefer signed integers. All callers changed.
9698 Detect integer overflow in repeat count.
9699 (message_dolog): Don't assume print length fits in 39 bytes.
9700 (display_mode_element): Don't assume strlen fits in int.
9702 * termcap.c: Don't assume sizes fit in int and never overflow.
9703 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9704 (gobble_line): Check for size-calculation overflow.
9706 * minibuf.c (Fread_buffer):
9707 * lread.c (intern, intern_c_string):
9708 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9709 Don't assume string length fits in int.
9711 * keyboard.c (parse_tool_bar_item):
9712 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9714 * font.c: Don't assume string length fits in int.
9715 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9716 Use ptrdiff_t, not int.
9717 (font_intern_prop): Don't assume string length fits in int.
9718 Don't assume integer property fits in fixnum.
9719 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9721 * filelock.c: Fix some buffer overrun and integer overflow issues.
9722 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9723 Reformulate so as not to need the command string.
9724 Invoke gzip -cd rather than gunzip, as it's more portable.
9725 (lock_info_type, lock_file_1, lock_file):
9726 Don't assume pid_t and time_t fit in unsigned long.
9727 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9728 (current_lock_owner): Prefer signed type for sizes.
9729 Use memcpy, not strncpy, where memcpy is what is really wanted.
9730 Don't assume (via atoi) that time_t and pid_t fit in int.
9731 Check for time_t and/or pid_t out of range, e.g., via a network share.
9732 Don't alloca where an auto var works fine.
9734 * fileio.c: Fix some integer overflow issues.
9735 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9736 Don't assume string length fits in int.
9737 (directory_file_name): Don't assume string length fits in long.
9738 (make_temp_name): Don't assume pid fits in int, or that its print
9739 length is less than 20.
9741 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9743 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9745 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9747 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9748 We prefer signed integers, even for size calculations.
9750 * emacs.c: Don't assume string length fits in 'int'.
9751 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9752 (main): Don't invoke strlen when not needed.
9754 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9755 (XD_DEBUG_MESSAGE): Don't waste a byte.
9757 * callproc.c (getenv_internal_1, getenv_internal)
9759 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9761 * lread.c (invalid_syntax): Omit length argument.
9762 All uses changed. This doesn't fix a bug, but it simplifies the
9763 code away from its former Hollerith-constant appearance, and it's
9764 one less 'int' to worry about when looking at integer-overflow issues.
9765 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9767 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9768 This didn't break anything, but it didn't help either.
9769 It's confusing to put a bogus integer in a place where the actual
9770 value does not matter.
9771 (LIST_END_P): Remove unused macro and its bogus comment.
9772 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9774 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9775 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9777 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9778 We prefer signed types, and the value cannot exceed the EMACS_INT
9779 range anyway (because otherwise the length would not be representable).
9780 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9781 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9782 This avoids a GCC warning when WIDE_EMACS_INT.
9784 * indent.c (sane_tab_width): New function.
9785 (current_column, scan_for_column, Findent_to, position_indentation)
9786 (compute_motion): Use it. This is just for clarity.
9787 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9789 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9791 * lisp.h (lint_assume): New macro.
9792 * composite.c (composition_gstring_put_cache):
9793 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9795 * editfns.c, insdel.c:
9796 Omit unnecessary forward decls, to simplify future changes.
9798 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9800 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9802 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9803 Use much-faster test for byte-length change.
9804 Don't assume string byte-length fits in 'int'.
9805 Check that character arg fits in 'int'.
9806 (mapcar1): Declare byte as byte, for clarity.
9808 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9810 * fns.c (concat): Catch string overflow earlier.
9811 Do not rely on integer wraparound.
9813 * dispextern.h (struct it.overlay_strings_charpos)
9814 (struct it.selective): Now EMACS_INT, not int.
9815 * xdisp.c (forward_to_next_line_start)
9816 (back_to_previous_visible_line_start)
9817 (reseat_at_next_visible_line_start, next_element_from_buffer):
9818 Don't arbitrarily truncate the value of 'selective' to int.
9820 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9822 * composite.c: Don't truncate sizes to 'int'.
9823 (composition_gstring_p, composition_reseat_it)
9824 (composition_adjust_point): Use EMACS_INT, not int.
9825 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9826 not EMACS_UINT, for indexes.
9828 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9830 * buffer.c: Include <verify.h>.
9831 (struct sortvec.priority, struct sortstr.priority):
9832 Now EMACS_INT, not int.
9833 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9834 (struct sortstr.size, record_overlay_string)
9835 (struct sortstrlist.size, struct sortlist.used):
9836 Don't truncate size to int.
9837 (record_overlay_string): Check for size-calculation overflow.
9838 (init_buffer_once): Check at compile-time, not run-time.
9840 2011-06-22 Jim Meyering <meyering@redhat.com>
9842 Don't leak an XBM-image-sized buffer
9843 * image.c (xbm_load): Free the image buffer after using it.
9845 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9848 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9849 that Sun C diagnosed.
9850 * fns.c (secure_hash): Fix pointer signedness issue.
9851 * intervals.c (static_offset_intervals): New function.
9852 (offset_intervals): Use it.
9854 2011-06-21 Leo Liu <sdl.web@gmail.com>
9857 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9860 * fns.c (secure_hash): Rename from crypto_hash_function and change
9861 the first arg to accept symbols.
9862 (Fsecure_hash): New primitive.
9863 (syms_of_fns): New symbols.
9865 2011-06-20 Deniz Dogan <deniz@dogan.se>
9867 * process.c (Fset_process_buffer): Clarify return value in
9870 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9872 * dispnew.c (add_window_display_history): Use BVAR.
9874 * xdisp.c (debug_method_add): Use BVAR.
9875 (check_window_end, dump_glyph_matrix, dump_glyph)
9876 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9878 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9881 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9882 check till after the cache is created in init_frame_faces.
9884 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9886 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9888 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9890 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9891 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9892 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9894 Improve buffer-overflow checking (Bug#8873).
9895 * fileio.c (Finsert_file_contents):
9896 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9897 Remove the old (too-loose) buffer overflow checks.
9898 They weren't needed, since make_gap checks for buffer overflow.
9899 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9900 The old code merely checked for Emacs fixnum overflow, and relied
9901 on undefined (wraparound) behavior. The new code avoids undefined
9902 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9904 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9905 Tune. Don't use wider integers than needed. Don't use alloca.
9906 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9908 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9910 * insdel.c, lisp.h (buffer_overflow): New function.
9911 (insert_from_buffer_1, replace_range, replace_range_2):
9912 * insdel.c (make_gap_larger):
9913 * editfns.c (Finsert_char):
9914 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9916 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9918 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9920 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9922 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9923 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9925 * fileio.c: Don't assume EMACS_INT fits in off_t.
9926 (emacs_lseek): New static function.
9927 (Finsert_file_contents, Fwrite_region): Use it.
9928 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9930 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9932 * fns.c: Don't overflow int when computing a list length.
9933 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9934 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9935 truncation on 64-bit hosts. Check for QUIT every
9936 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9937 faster and is responsive enough.
9938 (Flength): Report an error instead of overflowing an integer.
9939 (Fsafe_length): Return a float if the value is not representable
9940 as a fixnum. This shouldn't happen except in contrived situations.
9941 (Fnthcdr, Fsort): Don't assume list length fits in int.
9942 (Fcopy_sequence): Don't assume vector length fits in int.
9944 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9945 (header_size, word_size): New constants.
9946 (allocate_vectorlike): Don't check size overflow here.
9947 (allocate_vector): Check it here instead, since this is the only
9948 caller of allocate_vectorlike that could cause overflow.
9949 Check that the new vector's length is representable as a fixnum.
9951 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9952 The previous code was bogus. For example, next_almost_prime (32)
9953 returned 39, which is undesirable as it is a multiple of 3; and
9954 next_almost_prime (24) returned 25, which is a multiple of 5 so
9955 why was the code bothering to check for multiples of 7?
9957 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9959 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9961 Variadic C functions now count arguments with ptrdiff_t.
9962 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9963 Back then I didn't know that the Emacs coding style prefers signed int.
9964 Also, in the meantime I found a few more instances where arguments
9965 were being counted with int, which may truncate counts on 64-bit
9966 machines, or EMACS_INT, which may be unnecessarily wide.
9967 * lisp.h (struct Lisp_Subr.function.aMANY)
9968 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9969 Arg counts are now ptrdiff_t, not size_t.
9970 All variadic functions and their callers changed accordingly.
9971 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9972 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9973 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9974 * callint.c (Fcall_interactively): Check arg count for overflow,
9975 to avoid potential buffer overrun. Use signed char, not 'int',
9976 for 'varies' array, so that we needn't bother to check its size
9977 calculation for overflow.
9978 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9979 * eval.c (apply_lambda):
9980 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9981 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9982 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9984 * callint.c (Fcall_interactively): Don't use index var as event count.
9986 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9987 * mem-limits.h (SIZE): Remove; no longer used.
9989 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9991 Remove unnecessary casts.
9992 * xterm.c (x_term_init):
9993 * xfns.c (x_set_border_pixel):
9994 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9995 These aren't needed now that we assume ANSI C.
9997 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9998 It's more likely to cause problems (due to unsigned overflow)
10001 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10003 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10005 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10007 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10009 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10011 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10013 GLYPH_CODE_FACE returns EMACS_INT, not int.
10014 * dispextern.h (merge_faces):
10015 * xfaces.c (merge_faces):
10016 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10017 Don't assume EMACS_INT fits in int.
10019 * character.h (CHAR_VALID_P): Remove unused parameter.
10020 * fontset.c, lisp.h, xdisp.c: All uses changed.
10022 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10024 * fns.c (concat): Minor tuning based on overflow analysis.
10025 This doesn't fix any bugs. Use int to hold character, instead
10026 of constantly refetching from Emacs object. Use XFASTINT, not
10027 XINT, for value known to be a character. Don't bother comparing
10028 a single byte to 0400, as it's always less.
10030 * floatfns.c (Fexpt):
10031 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10033 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10036 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10038 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10039 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10040 incorrectly succeed when S was a string, because 4294967386 was
10041 truncated before it was used.
10043 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10044 Otherwise, an out-of-range integer could cause undefined behavior
10047 * composite.c: Use int, not EMACS_INT, for characters.
10048 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10049 EMACS_INT, for values that are known to be in character range.
10050 This doesn't fix any bugs but is the usual style inside Emacs and
10051 may generate better code on 32-bit machines.
10053 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10054 This is for reasons similar to the recent CHAR_STRING fix.
10055 * charset.c (Fencode_char): Check that character arg is actually
10056 a character. Pass an int to ENCODE_CHAR.
10057 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10058 wider than 'int', as a compile-time check to prevent future regressions
10061 * character.c (char_string): Remove unnecessary casts.
10063 Make sure a 64-bit char is never passed to CHAR_STRING.
10064 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10065 by silently ignoring the top 32 bits, allowing some values
10066 that were far too large to be valid characters.
10067 * character.h: Include <verify.h>.
10068 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10069 arguments are no wider than unsigned, as a compile-time check
10070 to prevent future regressions in this area.
10072 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10073 (Fsubst_char_in_region):
10075 * xdisp.c (decode_mode_spec_coding):
10076 Adjust to CHAR_STRING's new requirement.
10077 * editfns.c (Finsert_char, Fsubst_char_in_region):
10078 * fns.c (concat): Check that character args are actually
10079 characters. Without this test, these functions did the wrong
10080 thing with wildly out-of-range values on 64-bit hosts.
10082 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10083 These casts should not be needed on 32-bit hosts, either.
10084 * keyboard.c (read_char):
10085 * lread.c (Fload): Remove casts to unsigned.
10087 * lisp.h (UNSIGNED_CMP): New macro.
10088 This fixes comparison bugs on 64-bit hosts.
10089 (ASCII_CHAR_P): Use it.
10090 * casefiddle.c (casify_object):
10091 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10092 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10093 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10094 * dispextern.h (FACE_FROM_ID):
10095 * keyboard.c (read_char): Use UNSIGNED_CMP.
10097 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10098 not to EMACS_INT, to avoid GCC warning.
10100 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10102 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10103 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10104 isn't needed on 32-bit machines.
10106 * buffer.c (Fgenerate_new_buffer_name):
10107 Use EMACS_INT for count, not int.
10108 (advance_to_char_boundary): Return EMACS_INT, not int.
10110 * data.c (Qcompiled_function): Now static.
10112 * window.c (window_body_lines): Now static.
10114 * image.c (gif_load): Rename local to avoid shadowing.
10116 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10117 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10118 * alloc.c (make_save_value): Integer argument is now of type
10119 ptrdiff_t, not int.
10120 (mark_object): Use ptrdiff_t, not int.
10121 * lisp.h (pD): New macro.
10122 * print.c (print_object): Use it.
10124 * alloc.c: Use EMACS_INT, not int, to count objects.
10125 (total_conses, total_markers, total_symbols, total_vector_size)
10126 (total_free_conses, total_free_markers, total_free_symbols)
10127 (total_free_floats, total_floats, total_free_intervals)
10128 (total_intervals, total_strings, total_free_strings):
10129 Now EMACS_INT, not int. All uses changed.
10130 (Fgarbage_collect): Compute overall total using a double, so that
10131 integer overflow is less likely to be a problem. Check for overflow
10132 when converting back to an integer.
10133 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10134 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10135 These were 'int' variables that could overflow on 64-bit hosts;
10136 they were never used, so remove them instead of repairing them.
10137 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10138 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10139 Previously, this ceilinged at INT_MAX, but that doesn't work on
10141 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10143 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10144 (allocate_vectorlike): Check for ptrdiff_t overflow.
10145 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10146 when a (possibly-narrower) signed value would do just as well.
10147 We prefer using signed arithmetic, to avoid comparison confusion.
10149 * alloc.c: Catch some string size overflows that we were missing.
10150 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10151 for convenience in STRING_BYTES_MAX.
10152 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10153 The definition here is exact; the one in lisp.h was approximate.
10154 (allocate_string_data): Check for string overflow. This catches
10155 some instances we weren't catching before. Also, it catches
10156 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10157 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10158 and ptrdiff_t and EMACS_INT are both 64 bits.
10160 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10161 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10162 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10164 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10166 * alloc.c (Fmake_string): Check for out-of-range init.
10168 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10170 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10172 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10174 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

10177 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10178 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10179 (style_changed_cb): Call update_theme_scrollbar_width and call
10180 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10181 all frames (Bug#8505).
10182 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10183 Call gtk_window_set_resizable if HAVE_GTK3.
10184 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10185 and height if HAVE_GTK3 (Bug#8505).
10186 (scroll_bar_width_for_theme): New variable.
10187 (update_theme_scrollbar_width): New function.
10188 (xg_get_default_scrollbar_width): Move code to
10189 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

10192 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10194 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10196 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10198 * frame.c (make_frame): Call other_buffer_safely instead of
10201 * window.c (temp_output_buffer_show): Call display_buffer with
10202 second argument Vtemp_buffer_show_specifiers and reset latter
10203 immediately after the call.
10204 (Vtemp_buffer_show_specifiers): New variable.
10205 (auto_window_vscroll_p, next_screen_context_lines)
10206 (Vscroll_preserve_screen_position): Remove leading asterisks from

10757 (display_prop_intangible_p): Reimplement to call
10758 handle_display_spec instead of single_display_spec_intangible_p.

10770 value of a `display' property is a "replacing spec".
10771 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10772 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10802 * gnutls.c: Use Emacs's memory allocators.
10803 Without this change, the gnutls library would invoke malloc etc.
10804 directly, which causes problems on non-SYNC_INPUT hosts, and which
10805 runs afoul of improving memory_full behavior. (Bug#8761)
10806 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10807 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10808 xfree instead of the default malloc, realloc, free.
10809 (Fgnutls_boot): No need to check for memory allocation failure,
10810 since xmalloc does that for us.

10839 need to be updated by these changes.
10840 * fns.c (make_hash_table, maybe_resize_hash_table):
10841 Check for integer overflow with large hash tables.
10842 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10843 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10844 (SXHASH_REDUCE): New macro.
10845 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10846 Use it instead of discarding useful hash info with large hash values.
10847 (sxhash_float): New function.
10848 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10849 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10850 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10851 Rewrite to use FIXNUM_BITS, as this simplifies things.
10852 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10853 Adjust signatures to match updated version of code.
10854 (consing_since_gc): Now EMACS_INT, since a single hash table can
10855 use more than INT_MAX bytes.

10904 Make it possible to run ./temacs.
10906 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10907 syms_of_callproc does the same thing. Remove test for
10908 "initialized", do it in the caller.
10909 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10911 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10913 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10914 (read_minibuf): Use get_minibuffer.
10915 (syms_of_minibuf): Use DEFSYM.
10916 (Qmetadata): New var.
10917 * data.c (Qbuffer): Don't make it static.
10918 (syms_of_data): Use DEFSYM.
10920 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10922 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10923 (CCL_CODE_MIN): New macro.
10925 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10927 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10929 * eval.c (Qdebug): Now static.
10930 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10931 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10932 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10934 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10936 * image.c: Various fixes to ImageMagick code comments.
10937 (Fimagemagick_types): Doc fix.
10939 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10941 Minor fixes prompted by GCC 4.6.0 warnings.
10943 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10945 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10946 (x_clipboard_manager_save_all): Move extern decl to ...
10947 * xterm.h: ... here, so that it can be checked for consistency.
10949 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10951 * xselect.c (x_clipboard_manager_save_frame)
10952 (x_clipboard_manager_save_all): New functions.
10953 (Fx_clipboard_manager_save): Lisp function deleted.
10955 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10956 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10958 * xterm.h: Update prototype.
10960 2011-05-28 William Xu <william.xwl@gmail.com>
10962 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10963 exiting (Bug#8239).
10965 2011-05-28 Jim Meyering <meyering@redhat.com>
10967 Avoid a sign-extension bug in crypto_hash_function.
10968 * fns.c (to_uchar): Define.
10969 (crypto_hash_function): Use it to convert some newly-signed
10970 variables to unsigned, to avoid sign-extension bugs. For example,
10971 without this change, (md5 "truc") would evaluate to
10972 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10973 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10974 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10976 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10978 Integer overflow fixes.
10980 * dbusbind.c: Serial number integer overflow fixes.
10981 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10982 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10983 to hold a serial number that is too large for a fixnum.
10984 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10985 Check for serial numbers out of range. Decode any serial number
10986 that was so large that it became a float. (Bug#8722)
10988 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10989 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10990 Use XFASTINT rather than XUINT when numbers are nonnegative.
10991 (xd_append_arg, Fdbus_method_return_internal):
10992 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10993 arguments, check that Lisp number is nonnegative, rather than
10994 silently wrapping negative numbers around. (Bug#8722)
10995 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10998 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11000 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11002 ccl: Add integer overflow checks.
11003 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11004 (IN_INT_RANGE): New macros.
11005 (ccl_driver): Use them to check for integer overflow when
11006 decoding a CCL program. Many of the new checks are whether XINT (x)
11007 fits in int; it doesn't always, on 64-bit hosts. The new version
11008 doesn't catch all possible integer overflows, but it's an
11009 improvement. (Bug#8719)
11011 * alloc.c (make_event_array): Use XINT, not XUINT.
11012 There's no need for unsigned here.
11014 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11015 This follows up to the 2011-05-06 change that substituted uintptr_t
11016 for EMACS_INT. This case wasn't caught back then.
11018 Rework Fformat to avoid integer overflow issues.
11019 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11020 now (part of C89). Include <verify.h>.
11021 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11022 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11023 (Fformat): Avoid the prepass trying to compute sizes; it was only
11024 approximate and thus did not catch overflow reliably. Instead, walk
11025 through the format just once, formatting and computing sizes as we go,
11026 checking for integer overflow at every step, and allocating a larger
11027 buffer as needed. Keep track separately whether the format is
11028 multibyte. Keep only the most-recently calculated precision, rather
11029 than them all. Record whether each argument has been converted to
11030 string. Use EMACS_INT, not int, for byte and char and arg counts.
11031 Support field widths and precisions larger than INT_MAX. Avoid
11032 sprintf's undefined behavior with conversion specifications such as %#d
11033 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11034 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11035 formatting out-of-range floating point numbers with int
11036 formats. (Bug#8668)
11038 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11040 * data.c: Avoid integer truncation in expressions involving floats.
11041 * data.c: Include <intprops.h>.
11042 (arith_driver): When there's an integer overflow in an expression
11043 involving floating point, convert the integers to floating point
11044 so that the resulting value does not suffer from catastrophic
11045 integer truncation. For example, on a 64-bit host (* 4
11046 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11047 Do not rely on undefined behavior after integer overflow.
11049 merge count_size_as_multibyte, parse_str_to_multibyte
11050 * character.c, character.h (count_size_as_multibyte):
11051 Rename from parse_str_to_multibyte; all uses changed.
11052 Check for integer overflow.
11053 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11054 since it's now a duplicate of the other. This is more of
11055 a character than a buffer op, so better that it's in character.c.
11056 * fns.c, print.c: Adjust to above changes.
11058 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11060 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11062 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11064 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11065 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11066 (x_clipboard_manager_save): Now static.
11067 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11069 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11070 (crypto_hash_function): Now static.
11071 Fix pointer signedness problems. Avoid unnecessary initializations.
11073 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11075 * termhooks.h (Vselection_alist): Make it terminal-local.
11077 * terminal.c (create_terminal): Initialize it.
11079 * xselect.c: Support for clipboard managers.
11080 (Vselection_alist): Move to termhooks.h as terminal-local var.
11081 (LOCAL_SELECTION): New macro.
11082 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11083 (symbol_to_x_atom): Remove gratuitous arg.
11084 (x_handle_selection_request, lisp_data_to_selection_data)
11085 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11086 (x_own_selection, x_get_local_selection, x_convert_selection):
11087 New arg, specifying work frame. Use terminal-local Vselection_alist.
11088 (some_frame_on_display): Delete unused function.
11089 (Fx_own_selection_internal, Fx_get_selection_internal)
11090 (Fx_disown_selection_internal, Fx_selection_owner_p)
11091 (Fx_selection_exists_p): New optional frame arg.
11092 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11093 (x_handle_selection_clear): Don't treat other terminals with the
11094 same keyboard specially. Use the terminal-local Vselection_alist.
11095 (x_clear_frame_selections): Use Frun_hook_with_args.
11097 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11099 * xterm.h: Add support for those atoms.
11101 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11103 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11104 (converted_selections, conversion_fail_tag): New global variables.
11105 (x_selection_request_lisp_error): Free the above.
11106 (x_get_local_selection): Remove unnecessary code.
11107 (x_reply_selection_request): Args changed; handle arbitrary array
11108 of converted selections stored in converted_selections.
11109 Separate the XChangeProperty and SelectionNotify steps.
11110 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11111 (x_convert_selection): New function.
11112 (x_handle_selection_event): Simplify.
11113 (x_get_foreign_selection): Don't ignore incoming requests while
11114 waiting for an answer; this will fail when we implement
11115 SAVE_TARGETS, and seems unnecessary anyway.
11116 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11117 (Vx_sent_selection_functions): Doc fix.
11119 2011-05-26 Leo Liu <sdl.web@gmail.com>
11121 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11123 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11125 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11127 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11128 for fringe update if it has periodic bitmap.
11129 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11130 and fringe_bitmap_periodic_p.
11132 * fringe.c (get_fringe_bitmap_data): New function.
11133 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11134 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11135 row. Mark glyph row for fringe update if periodicity changed.
11137 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11138 for fringe update unless it has periodic bitmap.
11140 2011-05-25 Kenichi Handa <handa@m17n.org>
11142 * xdisp.c (get_next_display_element): Set correct it->face_id for
11143 a static composition.
11145 2011-05-24 Leo Liu <sdl.web@gmail.com>
11148 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11150 * fns.c (crypto_hash_function, Fsha1): New function.
11151 (Fmd5): Use crypto_hash_function.
11152 (syms_of_fns): Add Ssha1.
11154 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11156 * gnutls.c: Remove unused macros.
11157 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11158 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11159 Remove macros that are defined and never used.
11160 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11162 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11164 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11165 (Fx_get_selection_internal): Minor cleanup.
11166 (Fx_own_selection_internal): Rename arguments for consistency with
11169 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11171 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11173 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11175 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11177 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11179 * dispnew.c (scrolling_window): Don't exclude the case that the
11180 last enabled row in the desired matrix touches the bottom boundary.
11182 2011-05-21 Glenn Morris <rgm@gnu.org>
11184 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11185 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11186 and add some more files.
11188 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11190 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11191 report_file_error introduced by the change from 2011-05-07.
11193 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11195 * systime.h (Time): Define only if emacs is defined.
11196 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11197 where the include path doesn't have X11/X.h by default. See
11198 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11200 2011-05-20 Kenichi Handa <handa@m17n.org>
11202 * composite.c (find_automatic_composition): Fix previous change.
11204 2011-05-20 Glenn Morris <rgm@gnu.org>
11206 * lisp.mk: New file, split from Makefile.in.
11207 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11208 (shortlisp): Remove.
11209 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11211 2011-05-19 Glenn Morris <rgm@gnu.org>
11213 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11214 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11215 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11216 (lisp): Set the order to that of loadup.el.
11217 (shortlisp): Make it a copy of $lisp.
11218 (SOME_MACHINE_LISP): Remove.
11219 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11220 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11222 2011-05-18 Kenichi Handa <handa@m17n.org>
11224 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11225 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11226 (find_automatic_composition): Mostly rewrite for efficiency.
11228 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11230 * makefile.w32-in: Update dependencies.
11232 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11234 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11235 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11237 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11239 Fix some integer overflow issues, such as string length overflow.
11241 * insdel.c (count_size_as_multibyte): Check for string overflow.
11243 * character.c (lisp_string_width): Check for string overflow.
11244 Use EMACS_INT, not int, for string indexes and lengths; in
11245 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11246 the resulting string length overflows an EMACS_INT; instead,
11247 report a string overflow if no precision given. When checking for
11248 precision exhaustion, use a check that cannot possibly have
11249 integer overflow. (Bug#8675)
11250 * character.h (lisp_string_width): Adjust to new signature.
11252 * alloc.c (string_overflow): New function.
11253 (Fmake_string): Use it. This doesn't change behavior, but saves
11254 a few bytes and will simplify future changes.
11255 * character.c (string_escape_byte8): Likewise.
11256 * lisp.h (string_overflow): New decl.
11258 Fixups, following up to the user-interface timestamp change.
11259 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11260 for UI timestamps, instead of unsigned long.
11261 * msdos.c (mouse_get_pos): Likewise.
11262 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11263 * w32gui.h (Time): Define by including "systime.h" rather than by
11264 declaring it ourselves. (Bug#8664)
11266 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11267 * image.c (clear_image_cache): Likewise.
11269 * term.c (term_mouse_position): Don't assume time_t wraparound.
11271 Be more systematic about user-interface timestamps.
11272 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11273 and sometimes 'EMACS_UINT', to represent these timestamps.
11274 This change causes it to use 'Time' uniformly, as that's what X uses.
11275 This makes the code easier to follow, and makes it easier to catch
11276 integer overflow bugs such as Bug#8664.
11277 * frame.c (Fmouse_position, Fmouse_pixel_position):
11278 Use Time, not unsigned long, for user-interface timestamps.
11279 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11280 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11281 * keyboard.h (last_event_timestamp): Likewise.
11282 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11283 * menu.h (xmenu_show): Likewise.
11284 * term.c (term_mouse_position): Likewise.
11285 * termhooks.h (struct input_event.timestamp): Likewise.
11286 (struct terminal.mouse_position_hook): Likewise.
11287 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11288 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11289 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11290 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11291 what it was before.
11292 * menu.h, termhooks.h: Include "systime.h", for Time.
11294 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11295 Don't assume that the difference between two unsigned long values
11296 can fit into an integer. At this point, we know button_down_time
11297 <= event->timestamp, so the difference must be nonnegative, so
11298 there's no need to cast the result if double-click-time is
11299 nonnegative, as it should be; check that it's nonnegative, just in
11300 case. This bug is triggered when events are more than 2**31 ms
11301 apart (about 25 days). (Bug#8664)
11303 * xselect.c (last_event_timestamp): Remove duplicate decl.
11304 (x_own_selection): Remove needless cast to unsigned long.
11306 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11307 that always fit in int. Use a sentinel instead of a counter, to
11308 avoid a temp and to allay GCC's concerns about possible int overflow.
11309 * frame.h (struct frame): Use int for menu_bar_items_used
11310 instead of EMACS_INT, since it always fits in int.
11312 * menu.c (grow_menu_items): Check for int overflow.
11314 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11316 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11317 Before, the code was not consistent. These values cannot exceed
11318 2**31 - 1 so there's no need to make them unsigned.
11319 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11320 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11321 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11323 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11325 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11326 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11327 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11328 presumably because the widths might not match.
11330 * window.c (size_window): Avoid needless test at loop start.
11332 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11334 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11336 2011-05-12 Drew Adams <drew.adams@oracle.com>
11338 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11340 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11342 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11343 `width' to `bar_area_x' and `bar_area_width', respectively.
11344 (x_scroll_run): Take account of fringe background extension.
11346 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11347 Rename local vars `left' and `width' to `bar_area_x' and
11348 `bar_area_width', respectively.
11349 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11350 background extension.
11352 2011-05-10 Jim Meyering <meyering@redhat.com>
11354 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11356 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11358 * image.c (Finit_image_library): Return t for built-in image types,
11359 like pbm and xbm. (Bug#8640)
11361 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11363 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11365 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11367 * w32console.c (Fset_screen_color): Doc fix.
11368 (Fget_screen_color): New function.
11369 (syms_of_ntterm): Defsubr it.
11371 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11372 unlink the temporary file if Fcall_process didn't create it in the
11374 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11375 child process will be redirected to a file specified with `:file'.
11376 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11377 cue to call_process_cleanup not to close that handle.
11379 2011-05-07 Ben Key <bkey76@gmail.com>
11381 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11382 one of two shell specific rules, either bootstrap-temacs-CMD or
11383 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11384 to the previous implementation of the bootstrap-temacs rule.
11385 The bootstrap-temacs-CMD rule is similar to the previous
11386 implementation of the bootstrap-temacs rule except that it
11387 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11390 These changes, along with some changes to nt/configure.bat,
11391 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11392 earlier fix to add support for --cflags and --ldflags options
11393 that include quotes so that it works whether make uses cmd or
11396 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11398 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11399 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11401 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11402 a string. Handle both cases.
11403 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11404 (Fdbus_register_method): Use Qinvalid_function.
11406 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11408 * makefile.w32-in: Update dependencies.
11409 (LISP_H): Add inttypes.h and stdin.h.
11410 (PROCESS_H): Add unistd.h.
11412 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11414 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11415 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11417 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11419 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11421 * term.c (vfatal): Remove stray call to va_end.
11422 It's not needed and the C Standard doesn't allow it here anyway.
11424 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11425 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11427 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11430 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11432 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11434 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11436 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11438 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11440 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11441 * charset.c (Fdefine_charset_internal): Don't initialize
11442 charset.code_space[15]. The value was garbage, on hosts with
11443 32-bit int (Bug#8600).
11445 * lread.c (read_integer): Be more consistent with string-to-number.
11446 Use string_to_number to do the actual conversion; this avoids
11447 rounding errors and fixes some other screwups. Without this fix,
11448 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11449 (digit_to_number): Move earlier, for benefit of read_integer.
11450 Return -1 if the digit is out of range for the base, -2 if it is
11451 not a digit in any supported base. (Bug#8602)
11453 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11455 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11456 to match comment at start of function. This also removes a
11457 GCC warning about overflow in a 32+64-bit port.
11459 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11461 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11462 Reported by Stefan Monnier in
11463 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11464 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11465 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11467 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11468 (EMACS_UINTPTR): Likewise, with uintptr_t.
11470 * lisp.h: Prefer 64-bit EMACS_INT if available.
11471 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11472 on 32-bit hosts that have 64-bit int, so that they can access
11474 However, temporarily disable this change unless the temporary
11475 symbol WIDE_EMACS_INT is defined.
11477 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11479 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11480 This removes an assumption that EMACS_INT and long are the same
11481 width as pointers. The assumption is true for Emacs porting targets
11482 now, but we want to make other targets possible.
11483 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11484 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11485 In the rest of the code, change types of integers that hold casted
11486 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11487 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11488 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11489 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11490 No need to cast type when ORing.
11491 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11492 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11493 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11494 assume EMACS_INT is the same width as char *.
11495 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11496 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11497 Remove no-longer-needed casts.
11498 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11499 (xg_tool_bar_help_callback, xg_make_tool_item):
11500 Use EMACS_INTPTR to hold an integer
11501 that will be cast to void *; this can avoid a GCC warning
11502 if EMACS_INT is not the same width as void *.
11503 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11504 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11505 (current_message_1, set_message_1):
11506 Use a local to convert to proper width without a cast.
11507 * xmenu.c (dialog_selection_callback): Likewise.
11509 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11510 Also, don't assume VALBITS / RAND_BITS is less than 5,
11511 and don't rely on undefined behavior when shifting a 1 left into
11513 * lisp.h (get_random): Change signature to match.
11515 * lread.c (hash_string): Use size_t, not int, for hash computation.
11516 Normally we prefer signed values; but hashing is special, because
11517 it's better to use unsigned division on hash table sizes so that
11518 the remainder is nonnegative. Also, size_t is the natural width
11519 for hashing into memory. The previous code used 'int', which doesn't
11520 retain enough info to hash well into very large tables.
11521 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11523 * dbusbind.c: Don't possibly lose pointer info when converting.
11524 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11525 Use XPNTR rather than XHASH, so that the high-order bits of
11526 the pointer aren't lost when converting through void *.
11528 * eval.c (Fautoload): Don't double-shift a pointer.
11530 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11532 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11534 * gnutls.c (DEF_GNUTLS_FN):
11535 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11537 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11539 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11542 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11544 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11545 New version that can reserve upto 2GB of heap space.
11547 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11549 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

11553 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11554 `gnutls_certificate_set_x509_key_file'.
11556 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11558 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11559 Update dependencies.
11561 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11563 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11564 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11565 Remove unused parameter `fildes'.
11566 * process.c (read_process_output, send_process): Don't pass it.
11568 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11570 Fix previous change: the library cache is defined in w32.c.
11571 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11572 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11574 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11576 Implement dynamic loading of GnuTLS on Windows.
11578 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11579 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11580 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11583 * gnutls.c (Qgnutls_dll): Define.
11584 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11585 (gnutls_*): Declare function pointers.
11586 (init_gnutls_functions): New function to initialize function pointers.

11589 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11590 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11591 (emacs_gnutls_write, emacs_gnutls_read)
11592 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11593 (Fgnutls_available_p): New function.
11594 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11595 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11596 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11598 * image.c: Include w32.h.
11599 (Vimage_type_cache): Delete.
11600 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11601 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11602 (w32_delayed_load): Move to w32.c.
11604 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11606 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11607 (w32_delayed_load): Move from image.c. When loading a library, record
11608 its filename in the :loaded-from property of the library id.
11609 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11610 Initialize and staticpro them.
11611 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11613 * process.c: Include lisp.h before w32.h, not after.
11614 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11615 instead of gnutls_record_check_pending.
11617 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11619 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11621 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11622 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11625 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11627 * xterm.c (x_set_frame_alpha): Do not set property on anything
11628 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11630 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11632 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11634 2011-05-02 Juanma Barranquero <lekktu@gmail.com>

11644 (Qgnutls_bootprop_callbacks_verify): Make static.
11646 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11648 * callproc.c: Indentation fixup.
11650 * sysdep.c (wait_for_termination_1): Make static.
11651 (wait_for_termination, interruptible_wait_for_termination):
11652 Move after wait_for_termination_1.
11654 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11656 * sysdep.c (interruptible_wait_for_termination): New function
11657 which is like wait_for_termination, but allows keyboard
11660 * callproc.c (Fcall_process): Add (:file "file") as an option for
11662 (Fcall_process_region): Ditto.
11664 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11666 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11667 rather than `XVECTOR (FOO)->size'.
11669 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11670 inttypes.h, as a gnulib replacement is used if it not available in
11673 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11675 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11676 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11677 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11679 * coding.c (coding_alloc_by_realloc): Error out if destination
11680 will grow beyond MOST_POSITIVE_FIXNUM.
11681 (decode_coding_emacs_mule): Abort if there isn't enough place in
11682 charbuf for the composition carryover bytes. Reserve an extra
11683 space for up to 2 characters produced in a loop.
11684 (decode_coding_iso_2022): Abort if there isn't enough place in
11685 charbuf for the composition carryover bytes.
11687 2011-04-21 Eli Zaretskii <eliz@gnu.org>

11690 aborting when %lld or %lll format is passed.
11691 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11692 %llo or %llx format is passed. (Bug#8545)
11694 * window.c (window_scroll_line_based): Use a marker instead of
11695 simple variables to record original value of point. (Bug#7952)
11697 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11698 produced by %s or %c overflows available buffer space. (Bug#8545)
11700 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11702 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11703 (SIZE_MAX): Move defn after all includes, as they might #define it.
11705 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11707 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11709 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11711 * keyboard.c (Qdelayed_warnings_hook): Define.
11712 (command_loop_1): Run `delayed-warnings-hook'
11713 if Vdelayed_warnings_list is non-nil.
11714 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11715 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11717 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11719 * doprnt.c (doprnt): Don't return value smaller than the buffer
11720 size if the message was truncated. (Bug#8545).
11722 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11724 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11725 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11727 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11729 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11731 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11733 * makefile.w32-in: Update dependencies.
11735 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11737 Improve `doprnt' and its usage. (Bug#8545)
11738 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11739 `format_end'. Remove support for %l as a conversion specifier.
11740 Don't use xrealloc. Improve diagnostics when the %l size modifier
11741 is used. Update the commentary.
11743 * eval.c (verror): Simplify calculation of size_t.
11745 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11748 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11750 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11753 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11755 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11756 This makes this file independent of the recent pseudovector change.
11758 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11760 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11762 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11763 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11764 Remove unused local.
11765 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11767 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11768 GCC 4.6.0 optimizes based on type-based alias analysis.
11769 For example, if b is of type struct buffer * and v of type struct
11770 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11771 != &v->size, and therefore "v->size = 1; b->size = 2; return
11772 v->size;" must therefore return 1. This assumption is incorrect
11773 for Emacs, since it type-puns struct Lisp_Vector * with many other
11774 types. To fix this problem, this patch adds a new type struct
11775 vectorlike_header that documents the constraints on layout of vectors
11776 and pseudovectors, and helps optimizing compilers not get fooled
11777 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11778 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11779 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11781 (XSETPVECTYPE): Rewrite in terms of new macro.
11782 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11783 This is a bit clearer, and further avoids the possibility of
11784 undesirable aliasing.
11785 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11786 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11787 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11788 since Lisp_Subr is a special case (no "next" field).
11789 (ASIZE): Now uses header.size rather than size.
11790 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11791 to avoid the hassle of writing XVECTOR (foo)->header.size.
11792 (struct vectorlike_header): New type.
11793 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11794 object, to help avoid aliasing.
11795 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11796 (SUBRP): Likewise, since Lisp_Subr is a special case.
11797 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11798 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11799 (struct Lisp_Hash_Table): Combine first two members into a single
11800 struct vectorlike_header member. All uses of "size" and "next" members
11801 changed to be "header.size" and "header.next".
11802 * buffer.h (struct buffer): Likewise.
11803 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11804 * frame.h (struct frame): Likewise.
11805 * process.h (struct Lisp_Process): Likewise.
11806 * termhooks.h (struct terminal): Likewise.
11807 * window.c (struct save_window_data, struct saved_window): Likewise.
11808 * window.h (struct window): Likewise.
11809 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11810 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11811 * buffer.c (init_buffer_once): Likewise.
11812 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11814 * process.c (Fformat_network_address): Use local var for size,
11817 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11819 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11820 * data.c (atof): Remove decl; no longer used or needed.
11821 (digit_to_number): Move to lread.c.
11822 (Fstring_to_number): Use new string_to_number function, to be
11823 consistent with how the Lisp reader treats infinities and NaNs.
11824 Do not assume that floating-point numbers represent EMACS_INT
11825 without losing information; this is not true on most 64-bit hosts.
11826 Avoid double-rounding errors, by insisting on integers when
11827 parsing non-base-10 numbers, as the documentation specifies.
11828 * lisp.h (string_to_number): New decl, replacing ...
11829 (isfloat_string): Remove.
11830 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11831 (read1): Do not accept +. and -. as integers; this
11832 appears to have been a coding error. Similarly, do not accept
11833 strings like +-1e0 as floating point numbers. Do not report
11834 overflow for integer overflows unless the base is not 10 which
11835 means we have no simple and reliable way to continue.
11836 Break out the floating-point parsing into a new
11837 function string_to_number, so that Fstring_to_number parses
11838 floating point numbers consistently with the Lisp reader.
11839 (digit_to_number): Move here from data.c. Make it static inline.
11840 (E_CHAR, EXP_INT): Remove, replacing with ...
11841 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11842 (string_to_number): New function, replacing isfloat_string.
11843 This function checks for valid syntax and produces the resulting
11844 Lisp float number too. Rework it so that string-to-number
11845 no longer mishandles examples like "1.0e+". Use strtoumax,
11846 so that overflow for non-base-10 numbers is reported only when
11847 there's no portable and simple way to convert to floating point.
11849 * textprop.c (set_text_properties_1): Rewrite for clarity,
11850 and to avoid GCC warning about integer overflow.
11852 * intervals.h (struct interval): Use EMACS_INT for members
11853 where EMACS_UINT might cause problems. See
11854 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11855 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11856 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11858 (offset_intervals): Tell GCC not to worry about length overflow
11859 when negating a negative length.
11861 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11862 (overrun_check_free): Likewise.
11864 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11865 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11868 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11869 (gnutls_make_error): Rename local to avoid shadowing.
11870 (gnutls_emacs_global_deinit): ifdef out; not used.
11871 (Fgnutls_boot): Use const for pointer to readonly storage.
11872 Comment out unused local. Fix pointer signedness problems.
11874 * lread.c (openp): Don't stuff size_t into an 'int'.
11875 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11876 about possible signed overflow.
11878 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11879 (GDK_KEY_g): Don't define if already defined.
11880 (xg_prepare_tooltip): Avoid pointer signedness problem.
11881 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11883 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11884 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11886 * xfns.c (Fx_window_property): Simplify a bit,
11887 to make a bit faster and to avoid GCC 4.6.0 warning.
11888 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11890 * fns.c (internal_equal): Don't assume size_t fits in int.
11892 * alloc.c (compact_small_strings): Tighten assertion a little.
11894 Replace pEd with more-general pI, and fix some printf arg casts.
11895 * lisp.h (pI): New macro, generalizing old pEd macro to other
11896 conversion specifiers. For example, use "...%"pI"d..." rather
11897 than "...%"pEd"...".
11898 (pEd): Remove. All uses replaced with similar uses of pI.
11899 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11900 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11901 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11902 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11903 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11904 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11905 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11907 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11908 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11909 * print.c (safe_debug_print, print_object): Likewise.
11910 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11912 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11913 avoiding the 0 flag, which is not portable.
11914 * process.c (Fmake_network_process): Use pI to avoid cast.
11915 * region-cache.c (pp_cache): Likewise.
11916 * xdisp.c (decode_mode_spec): Likewise.
11917 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11918 behavior on 64-bit hosts with printf arg.
11919 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11920 (x_stop_queuing_selection_requests): Likewise.
11921 (x_get_window_property): Don't truncate byte count to an 'int'
11924 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11925 here, since it parses constructs like leading '-' and spaces,
11926 which are not wanted; and it overflows with large numbers.
11927 Instead, simply match F[0-9]+, which is what is wanted anyway.
11929 * alloc.c: Remove unportable assumptions about struct layout.
11930 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11931 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11932 (allocate_vectorlike, make_pure_vector): Use the new macros,
11933 plus offsetof, to remove unportable assumptions about struct layout.
11934 These assumptions hold on all porting targets that I know of, but
11935 they are not guaranteed, they're easy to remove, and removing them
11936 makes further changes easier.
11938 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11939 This doesn't fix a bug but makes the code clearer.
11940 (string_overrun_cookie): Now const. Use initializers that
11941 don't formally overflow signed char, to avoid warnings.
11942 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11943 can cause Emacs to crash when string overrun checking is enabled.
11944 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11945 multiple of sizeof (EMACS_INT); it need not be, if
11946 alignof(EMACS_INT) < sizeof (EMACS_INT).
11947 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11949 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11956 supposed to be handshaking. (Bug#8556)
11957 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11959 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

11969 * alloc.c (check_sblock, check_string_bytes)
11970 (check_string_free_list): Convert to standard C.
11972 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11974 * w32.c (emacs_gnutls_push): Fix typo.
11976 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11978 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11979 "cast to pointer from integer of different size".
11981 Improve doprnt and its use in verror. (Bug#8545)
11982 * doprnt.c (doprnt): Document the set of format control sequences
11983 supported by the function. Use SAFE_ALLOCA instead of always
11986 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11987 is one byte too soon. Don't use xrealloc; instead xfree and
11990 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11992 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11995 * gnutls.c: Renamed global_initialized to
11996 gnutls_global_initialized. Added internals for the
11997 :verify-hostname-error, :verify-error, and :verify-flags
11998 parameters of `gnutls-boot' and documented those parameters in the
11999 docstring. Start callback support.
12000 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12001 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12002 on error. Return error code.

12004 (emacs_gnutls_read): Likewise.
12005 (Fgnutls_boot): Return handshake error code.

12062 changes in globals.h immediately force recompilation.
12063 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12064 $(CURDIR)/s/ms-w32.h.

12069 <char-direction-table>: Deleted.
12071 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12073 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12074 * doprnt.c: Include limits.h.
12075 (SIZE_MAX): New macro.
12076 (doprnt): Return a size_t value. 2nd arg is now size_t.
12077 Many local variables are now size_t instead of int or unsigned.
12078 Improve overflow protection. Support `l' modifier for integer
12079 conversions. Support %l conversion. Don't assume an EMACS_INT
12080 argument for integer conversions and for %c.
12082 * lisp.h (doprnt): Restore prototype.
12084 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12085 $(SRC)/character.h.
12087 * Makefile.in (base_obj): Add back doprnt.o.
12089 * deps.mk (doprnt.o): Add back prerequisites.
12090 (callint.o): Depend on character.h.
12092 * eval.c (internal_lisp_condition_case): Include the handler
12093 representation in the error message.
12094 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12095 when breaking from the loop.
12097 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12099 * callint.c (Fcall_interactively): When displaying error message
12100 about invalid control letter, pass the character's codepoint, not
12101 a pointer to its multibyte form. Improve display of the character
12102 in octal and display also its hex code.
12104 * character.c (char_string): Use %x to display the (unsigned)
12105 codepoint of an invalid character, to avoid displaying a bogus
12108 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12109 `error', not SYMBOL_NAME itself.
12111 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12112 character arguments to `error'.
12114 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12115 to `error' in error message about FINAL_CHAR argument. Make sure
12116 FINAL_CHAR is a character, and use %c when it is passed as
12117 argument to `error'.

12181 Define only if needed.
12183 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12184 by pacifying GCC about it. Maybe it's time to retire it?
12185 * xfaces.c (USG, __TIMEVAL__): Likewise.
12187 * dispextern.h (struct redisplay_interface): Rename param
12188 to avoid shadowing.
12189 * termhooks.h (struct terminal): Likewise.
12190 * xterm.c (xembed_send_message): Likewise.
12192 * insdel.c (make_gap_smaller): Define only if
12193 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
12195 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
12198 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
12199 so that we aren't warned about unused symbols.
12201 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
12203 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
12205 * xfns.c (x_real_positions): Mark locals as initialized.
12207 * xmenu.c (xmenu_show): Don't use uninitialized vars.
12209 * xterm.c: Fix problems found by static analysis with other toolkits.
12210 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
12211 (x_dispatch_event): Declare static if USE_GTK, and
12212 define if USE_GTK || USE_X_TOOLKIT.
12213 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
12214 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
12215 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
12216 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
12218 * xmenu.c (menu_help_callback): Pointer type fixes.
12219 Use const pointers when pointing at readonly data. Avoid pointer
12220 signedness clashes.
12221 (FALSE): Remove unused macro.

12306 * nsfont.m: Fixed bugs in ns_get_family and
12307 ns_descriptor_to_entity that were caused by using free to
12308 deallocate memory blocks that were allocated by xmalloc (via

12311 --enable-checking=xmallocoverrun). xfree is now used to
12312 deallocate these memory blocks.

12663 * buffer.c (buffer_count): Remove unused var.
12665 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
12666 so that it's not optimized away.
12667 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12668 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12669 exported only to the debugger.
12671 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12672 * atimer.h (run_all_atimers): Remove; not exported.
12674 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12675 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12676 was inaccessible from Lisp.
12677 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12678 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12680 alloc.c: Import and export fewer symbols, and remove unused items.
12681 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12683 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12684 it's not optimized away by whole-program optimization.
12685 (message_enable_multibyte, free_misc): Remove.
12686 (catchlist, handlerlist, mark_backtrace):
12687 Declare only if BYTE_MARK_STACK.
12688 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
12689 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
12690 (message_enable_multibyte): Remove decl.
12691 (free_misc, interval_free_list, float_block, float_block_index):
12692 (n_float_blocks, float_free_list, cons_block, cons_block_index):
12693 (cons_free_list, last_marked_index):
12695 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
12696 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12697 (mark_backtrace): Define only if BYTE_MARK_STACK.
12698 * xdisp.c (message_enable_multibyte): Now static.
12700 Declare Lisp_Object Q* variables to be 'static' if not exported.
12701 This makes it easier for human readers (and static analyzers)
12702 to see whether these variables are used from other modules.
12703 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12704 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12705 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
12706 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
12707 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
12708 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
12709 * xmenu.c, xselect.c:
12710 Declare Q* vars static if they are not used in other modules.
12711 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
12712 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12713 Remove decls of unexported vars.
12714 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12716 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12718 Make Emacs functions such as Fatom 'static' by default.
12719 This makes it easier for human readers (and static analyzers)
12720 to see whether these functions can be called from other modules.
12721 DEFUN now defines a static function. To make the function external
12722 so that it can be used in other C modules, use the new macro DEFUE.
12723 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12724 (Finit_image_library):
12725 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12726 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12727 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12728 Remove decls, since these functions are now static.
12729 (Funintern, Fget_internal_run_time): New decls, since these functions
12730 were already external.
12732 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12733 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
12734 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
12735 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
12736 * keyboard.c, keymap.c, lread.c:
12737 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
12738 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
12739 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12740 Mark functions with DEFUE instead of DEFUN,
12741 if they are used in other modules.
12742 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12743 decls for now-static functions.
12744 * buffer.h (Fdelete_overlay): Remove decl.
12745 * callproc.c (Fgetenv_internal): Mark as internal.
12746 * composite.c (Fremove_list_of_text_properties): Remove decl.

12750 * doc.c (Fdocumntation_property): New forward static decl.
12751 * eval.c (Ffetch_bytecode): New forward static decl.
12752 (Funintern): Remove extern decl; now in .h file where it belongs.
12753 * fileio.c (Fmake_symbolic_link): New forward static decl.
12754 * image.c (Finit_image_library): New forward static decl.
12755 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12756 * intervals.h (Fprevious_property_change):
12757 (Fremove_list_of_text_properties): Remove decls.
12758 * keyboard.c (Fthis_command_keys): Remove decl.
12759 (Fcommand_execute): New forward static decl.
12760 * keymap.c (Flookup_key): New forward static decl.
12761 (Fcopy_keymap): Now static.
12762 * keymap.h (Flookup_key): Remove decl.
12763 * process.c (Fget_process): New forward static decl.
12764 (Fprocess_datagram_address): Mark as internal.
12765 * syntax.c (Fsyntax_table_p): New forward static decl.
12766 (skip_chars): Remove duplicate decl.

12775 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12777 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12780 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12782 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12783 when at ZV. (Bug#8487)
12785 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12787 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12789 * keyboard.c (parse_tool_bar_item): Likewise.
12790 * sound.c (sound_cleanup, alsa_close): Likewise.
12791 * termcap.c (tgetent): Likewise.
12792 * xfns.c (x_default_font_parameter): Likewise.
12793 * xsettings.c (read_and_apply_settings): Likewise.
12795 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12796 (overrun_check_free): Protoize.
12798 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12800 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12801 since callers should never pass a negative size.
12802 Change the signature to match that of plain 'read' and 'write'; see
12803 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12804 * lisp.h: Update prototypes of emacs_write and emacs_read.
12806 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12808 * xdisp.c (redisplay_window): Don't try to determine the character
12809 position of the scroll margin if the window start point w->startp
12810 is outside the buffer's accessible region. (Bug#8468)
12812 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12814 Fix write-region and its subroutines for buffers > 2GB.
12815 * fileio.c (a_write, e_write): Modify declaration of arguments and
12816 local variables to support buffers larger than 2GB.
12817 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12819 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12820 argument, local variables, and return value.
12822 * lisp.h: Update prototypes of emacs_write and emacs_read.
12824 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12826 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12828 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12830 Fix more problems found by GCC 4.6.0's static checks.
12832 * xdisp.c (vmessage): Use a better test for character truncation.
12834 * charset.c (load_charset_map): <, not <=, for optimization,
12835 and to avoid potential problems with integer overflow.
12836 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12837 * casetab.c (set_identity, shuffle): Likewise.
12838 * editfns.c (Fformat): Likewise.
12839 * syntax.c (skip_chars): Likewise.
12841 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12842 This also lets GCC 4.6.0 generate slightly better loop code.
12844 * callint.c (Fcall_interactively): <, not <=, for optimization.
12845 (Fcall_interactively): Count the number of arguments produced,
12846 not the number of arguments given. This is simpler and lets GCC
12847 4.6.0 generate slightly better code.
12849 * ftfont.c: Distingish more carefully between FcChar8 and char.
12850 The previous code passed unsigned char * to a functions like
12851 strlen and xstrcasecmp that expect char *, which does not
12852 conform to the C standard.
12853 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12854 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12855 char * when the C standard requires it.
12857 * keyboard.c (read_char): Remove unused var.
12859 * eval.c: Port to Windows vsnprintf (Bug#8435).
12860 Include <limits.h>.
12861 (SIZE_MAX): Define if the headers do not.
12862 (verror): Do not give up if vsnprintf returns a negative count.
12863 Instead, grow the buffer. This ports to Windows vsnprintf, which
12864 does not conform to C99. Problem reported by Eli Zaretskii.
12865 Also, simplify the allocation scheme, by avoiding the need for
12866 calling realloc, and removing the ALLOCATED variable.
12868 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12870 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12871 But keep the doprint source code for now, as we might revamp it
12872 and use it again (Bug#8435).
12873 * lisp.h (doprnt): Remove.
12874 * Makefile.in (base_obj): Remove doprnt.o.
12875 * deps.mk (doprnt.o): Remove.
12877 error: Print 32- and 64-bit integers portably (Bug#8435).
12878 Without this change, on typical 64-bit hosts error ("...%d...", N)
12879 was used to print both 32- and 64-bit integers N, which relied on
12880 undefined behavior.
12881 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12882 * lisp.h (error, verror): Mark as printf-like functions.
12883 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12884 Report overflow in size calculations when allocating printf buffer.
12885 Do not truncate output string at its first null byte.
12886 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12887 Truncate the output at a character boundary, since vsnprintf does not
12889 * charset.c (check_iso_charset_parameter): Convert internal
12890 character to string before calling 'error', since %c now has the
12892 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12893 overflow when computing char to be passed to 'error'. Do not
12894 pass Lisp_Object to 'error'; pass the integer instead.
12895 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12896 formatted with plain %d.
12898 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12900 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12902 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12904 * xterm.c (x_catch_errors): Remove duplicate declaration.
12906 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12908 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12910 2011-04-10 Jim Meyering <meyering@redhat.com>
12912 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12913 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12914 return ssize_t not "int", and use size_t as the buffer length.
12915 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12916 * gnutls.h: Update declarations.
12917 * process.c (read_process_output): Use ssize_t, to match.
12918 (send_process): Likewise.
12920 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12922 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12924 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12926 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12927 Use unsigned char, to match FcChar8 type definition.
12929 * xterm.c (handle_one_xevent):
12930 * xmenu.c (create_and_show_popup_menu):
12931 * xselect.c (x_decline_selection_request)
12932 (x_reply_selection_request): Avoid type-punned deref of X events.
12934 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12936 Fix some uses of `int' instead of EMACS_INT.
12937 * search.c (string_match_1, fast_string_match)
12938 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12939 (scan_buffer, find_next_newline_no_quit)
12940 (find_before_next_newline, search_command, Freplace_match)
12941 (Fmatch_data): Make some `int' variables be EMACS_INT.
12943 * xdisp.c (display_count_lines): 3rd argument and return value now
12944 EMACS_INT. All callers changed.
12945 (pint2hrstr): Last argument is now EMACS_INT.
12947 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12948 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12949 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12950 (decode_coding_utf_16, decode_coding_emacs_mule)
12951 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12952 (decode_coding_ccl, decode_coding_charset)
12953 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12954 (decode_coding_iso_2022, decode_coding_emacs_mule)
12955 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12956 <char_offset, last_offset>: Declare EMACS_INT.

12960 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12961 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12963 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12964 (encode_invocation_designation): Last argument P_NCHARS is now
12966 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12967 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12969 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12972 * ccl.c (Fccl_execute_on_string): Declare some variables
12975 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12977 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12979 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12981 * process.c (Fformat_network_address): Doc fix.
12983 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12985 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12987 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12989 * keyboard.c (read_char): Call Lisp function help-form-show,
12990 instead of using internal_with_output_to_temp_buffer.
12991 (Qhelp_form_show): New var.
12992 (syms_of_keyboard): Use DEFSYM macro.
12994 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13001 (list_processes_1): Delete.
13003 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13005 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13007 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13009 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13011 Fix more problems found by GCC 4.6.0's static checks.
13013 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13015 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13017 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13019 * xdisp.c (vmessage): Mark as a printf-like function.
13021 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13023 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13025 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13026 printf-like functions.

13028 to system-supplied API.
13030 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13032 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13033 This avoids several warnings with gcc -Wstrict-overflow.
13034 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13035 directly, rather than having caller test rule sign. This avoids
13036 some unnecessary tests.
13037 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13038 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13039 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13041 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13042 (xfont_open): Avoid unnecessary tests.
13044 * composite.c (composition_gstring_put_cache): Use unsigned integer.

13053 by using the new macro.
13055 * textprop.c (set_text_properties_1): Change while to do-while,
13056 since the condition is always true at first.
13058 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13059 (interval_deletion_adjustment): Return unsigned value.
13062 * process.c (list_processes_1, create_pty, read_process_output):
13063 (exec_sentinel): Remove vars that were set but not used.
13064 (create_pty): Remove unnecessary "volatile"s.

13078 * print.c (print_error_message): Avoid int overflow.
13080 * font.c (font_list_entities): Redo for clarity,
13081 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13083 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13084 (font_score): Avoid potential overflow in diff calculation.
13086 * fns.c (substring_both): Remove var that is set but not used.
13087 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13089 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13091 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13092 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13093 can always succeed if overflow has undefined behavior.
13095 * search.c (boyer_moore, wordify): Remove vars set but not used.
13096 (wordify): Omit three unnecessary tests.
13098 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13099 All callers changed. This avoids the need for an unused var.
13101 * casefiddle.c (casify_region): Remove var that is set but not used.
13103 * dired.c (file_name_completion): Remove var that is set but not used.
13105 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13107 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13108 (Finsert_file_contents): Remove unnecessary code checking fd.
13110 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13111 Check for integer overflow on size calculations.
13113 * buffer.c (Fprevious_overlay_change): Remove var that is set
13116 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13117 Remove vars that are set but not used.
13118 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13119 (timer_check_2): Mark vars as initialized.
13121 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13123 * image.c (lookup_image): Remove var that is set but not used.
13124 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13126 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13127 that are set but not used.
13129 * xfns.c (make_invisible_cursor): Don't return garbage
13130 if XCreateBitmapFromData fails (Bug#8410).
13132 * xselect.c (x_get_local_selection, x_handle_property_notify):
13133 Remove vars that are set but not used.
13135 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13136 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13138 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13139 Remove var that is set but not used.
13140 (scroll_bar_windows_size): Now size_t, not int.
13141 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13142 Check for overflow.
13144 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13145 (map_tty_color) [!defined MSDOS]: Likewise.
13147 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13149 * coding.c: Remove vars that are set but not used.
13150 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13151 All callers changed.
13152 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13153 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13154 (decode_coding_charset): Remove vars that are set but not used.
13156 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13157 that is set but not used.
13159 * print.c (print_object): Remove var that is set but not used.
13161 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13162 The gnulib version avoids calling malloc in the usual case,
13163 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13164 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13165 * filelock.c (current_lock_owner): Likewise.
13166 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13167 * sysdep.c: Include allocator.h, careadlinkat.h.
13168 (emacs_no_realloc_allocator): New static constant.
13169 (emacs_readlink): New function.
13170 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13171 ../lib/careadlinkat.h.
13173 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13175 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13176 first non-nil return value).

13187 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13188 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13190 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13191 and thereabouts. All callers changed.
13192 (get_per_char_metric): Remove parameter `f', unused since
13193 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13195 2011-04-02 Jim Meyering <meyering@redhat.com>
13197 do not dereference NULL upon failed strdup
13198 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13199 (ns_get_family): Likewise.
13201 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13203 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13205 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13207 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13210 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13212 Add lexical binding.
13214 * window.c (Ftemp_output_buffer_show): New fun.
13215 (Fsave_window_excursion):
13216 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13218 * lread.c (lisp_file_lexically_bound_p): New function.
13219 (Fload): Bind Qlexical_binding.
13220 (readevalloop): Remove `evalfun' arg.
13221 Bind Qinternal_interpreter_environment.
13222 (Feval_buffer): Bind Qlexical_binding.
13223 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13225 (syms_of_lread): Declare `lexical-binding'.
13227 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13229 * keyboard.c (eval_dyn): New fun.
13230 (menu_item_eval_property): Use it.
13232 * image.c (parse_image_spec): Use Ffunctionp.
13234 * fns.c (concat, mapcar1): Accept byte-code-functions.
13236 * eval.c (Fsetq): Handle lexical vars.
13237 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13238 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13239 (FletX, Flet): Obey lexical binding.
13240 (Fcommandp): Handle closures.
13241 (Feval): New `lexical' arg.
13242 (eval_sub): New function extracted from Feval. Use it almost
13243 everywhere where Feval was used. Look up vars in lexical env.
13245 (Ffunctionp): Move from subr.el.
13246 (Ffuncall): Handle closures.
13247 (apply_lambda): Remove `eval_flags'.
13248 (funcall_lambda): Handle closures and new byte-code-functions.
13249 (Fspecial_variable_p): New function.
13250 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13251 but without exporting it to Lisp.
13253 * doc.c (Fdocumentation, store_function_docstring):
13254 * data.c (Finteractive_form): Handle closures.
13256 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13259 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13261 (exec_byte_code): New function extracted from Fbyte_code to handle new
13262 calling convention for byte-code-functions. Add new byte-codes.
13264 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13266 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13268 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13270 * xdisp.c (redisplay_internal): Fix prototype.
13272 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13274 * xdisp.c (SCROLL_LIMIT): New macro.
13275 (try_scrolling): Use it when setting scroll_limit.
13276 Limit scrolling to 100 screen lines.
13277 (redisplay_window): Even when falling back on "recentering",
13278 position point in the window according to scroll-conservatively,
13279 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13281 (try_scrolling): When point is above the window, allow searching
13282 as far as scroll_max, or one screenful, to compute vertical
13283 distance from PT to the scroll margin position. This prevents
13284 try_scrolling from unnecessarily failing when
13285 scroll-conservatively is set to a value slightly larger than the
13286 window height. Clean up the case of PT below the margin at bottom
13287 of window: scroll_max can no longer be INT_MAX. When aggressive
13288 scrolling is in use, don't let point enter the opposite scroll
13289 margin as result of the scroll.
13290 (syms_of_xdisp) <scroll-conservatively>: Document the
13291 threshold of 100 lines for never-recentering scrolling.
13293 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

13298 (message_log_check_duplicate): Remove parameters `prev_bol' and
13299 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13300 (redisplay_internal): Remove parameter `preserve_echo_area',
13301 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13303 * indent.c (Fvertical_motion):
13304 * window.c (window_scroll_pixel_based, Frecenter):
13305 Don't pass `need_y_p' to `move_it_by_lines'.
13307 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13309 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13310 steal a few bits to be more compact.
13311 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13312 Remove unneeded casts.
13314 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13316 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13318 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13319 binding" message (bug#7967).
13321 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13323 Fix more problems found by GCC 4.6.0's static checks.
13325 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13326 Remove unused local var.
13328 * editfns.c (Fmessage_box): Remove unused local var.
13330 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13331 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13332 Omit unused local vars.
13333 * window.c (shrink_windows): Omit unused local var.
13334 * menu.c (digest_single_submenu): Omit unused local var.
13335 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13336 Omit unused local var.
13338 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13339 Don't assume string length fits in int.
13340 (keyremap_step, read_key_sequence): Use size_t for sizes.
13341 (read_key_sequence): Don't check last_real_key_start redundantly.
13343 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13344 instead of alloca (Bug#8344).
13346 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13347 (Fbacktrace_frame): Don't assume nframes fits in int.
13349 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13351 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13354 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13356 * cm.c (calccost): Turn while-do into do-while, for clarity.
13358 * keyboard.c (syms_of_keyboard): Use the same style as later
13359 in this function when indexing through an array. This also
13360 works around GCC bug 48267.
13362 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13364 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13366 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13367 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13369 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13370 This avoids undefined behavior on integer overflow, and is a bit
13371 more convenient anyway since it is compared to a size_t variable.
13373 Variadic C functions now count arguments with size_t, not int.
13374 This avoids an unnecessary limitation on 64-bit machines, which
13375 caused (substring ...) to crash on large vectors (Bug#8344).

13385 * fns.c (concat): Likewise.
13386 * frame.c (x_set_frame_parameters): Likewise.
13387 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13388 0 if not found, not -1. All callers changed.
13390 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13391 (stack_copy_size): Now size_t, not int.
13392 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13394 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13396 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13397 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13398 All callers changed.
13400 * lisp.h (multibyte_char_to_unibyte):
13401 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13402 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13413 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13414 don't set the hook to nil, but remove the offending function instead.
13415 (Qcommand_hook_internal): Remove, unused.
13416 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13417 Vcommand_hook_internal.

13420 (funcall_nil, funcall_not): New functions.
13421 (run_hook_with_args): Call each function through a `funcall' argument.

13435 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13436 All callers changed.
13438 * w32.c (_wsa_errlist): Use braces for struct initializers.
13440 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

13506 * keyboard.c (readable_events):
13507 * process.c (wait_reading_process_output):
13508 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

13556 Remove unused variable `width'.
13558 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
13560 * w32term.c (x_set_glyph_string_clipping):
13561 Don't pass uninitialized region to CombineRgn.

13585 2011-03-23 Julien Danjou <julien@danjou.info>
13587 * term.c (Fsuspend_tty, Fresume_tty):
13588 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13589 * window.c (temp_output_buffer_show):
13590 * insdel.c (signal_before_change):
13591 * frame.c (Fhandle_switch_frame):
13592 * fileio.c (Fdo_auto_save):

13595 * cmds.c (internal_self_insert):
13596 * callint.c (Fcall_interactively):
13597 * buffer.c (Fkill_all_local_variables):
13598 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13600 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13601 unconditionally since it does the check itself.
13603 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13605 Fix more problems found by GCC 4.5.2's static checks.
13607 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13608 the first time through the loop, since we know p0 < p1 then.
13609 This also avoids a gcc -Wstrict-overflow warning.
13611 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13612 leading to a memory leak, possible in functions like
13613 load_charset_map_from_file that can allocate an unbounded number
13614 of objects (Bug#8318).
13616 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13617 that could (at least in theory) be that large.
13619 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13620 This is less likely to overflow, and avoids undefined behavior if
13621 overflow does occur. All callers changed. Use strtoul to scan
13622 for the unsigned long integer.
13623 (pint2hrstr): Simplify and tune code slightly.
13624 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13626 * scroll.c (do_scrolling): Work around GCC bug 48228.
13627 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

13632 This also avoids a warning with gcc -Wstrict-overflow.
13634 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13637 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13639 * process.c (Fmake_network_process): Use socklen_t, not int,
13640 where POSIX says socklen_t is required in portable programs.
13641 This fixes a porting bug on hosts like 64-bit HP-UX, where
13642 socklen_t is wider than int (Bug#8277).
13643 (Fmake_network_process, server_accept_connection):
13644 (wait_reading_process_output, read_process_output):
13647 * process.c: Rename or move locals to avoid shadowing.

13657 Make tparam.h and terminfo.c consistent.
13658 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13659 Include tparam.h instead, since it declares them.
13660 * cm.h (PC): Remove extern decl; tparam.h now does this.
13661 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13662 * terminfo.c: Include tparam.h, to check interfaces.
13663 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13664 (tparam): Adjust signature to match interface in tparam.h;
13665 this removes some undefined behavior. Check that outstring and len
13666 are zero, which they always are with Emacs.
13667 * tparam.h (PC, BC, UP): New extern decls.
13669 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13670 (xftfont_open): Rename locals to avoid shadowing.
13672 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13673 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13674 (OTF_TAG_SYM): Omit macro if not needed.

13682 * xml.c (make_dom): Now static.
13684 * composite.c (composition_compute_stop_pos): Rename local to
13686 (composition_reseat_it): Remove unused locals.
13687 (find_automatic_composition, composition_adjust_point): Likewise.
13688 (composition_update_it): Mark var as initialized.
13689 (find_automatic_composition): Mark vars as initialized,
13690 with a FIXME (Bug#8290).

13693 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13694 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13695 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13696 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13697 to avoid shadowing.
13699 * textprop.c (property_change_between_p): Remove; unused.
13701 * intervals.c (interval_start_pos): Now static.
13703 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13706 Rename locals to avoid shadowing.
13708 * sound.c (wav_play, au_play, Fplay_sound_internal):
13709 Fix pointer signedness.
13710 (alsa_choose_format): Remove unused local var.
13711 (wav_play): Initialize a variable to 0, to prevent undefined
13712 behavior (Bug#8278).
13714 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13716 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13718 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13719 clobbering (Bug#8298).
13720 * sysdep.c (sys_subshell): Likewise.
13721 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13723 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13724 This should get cleaned up, so that child_setup has the
13725 same signature on all platforms.
13727 * callproc.c (call_process_cleanup): Now static.
13728 (relocate_fd): Rename locals to avoid shadowing.
13730 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13732 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13733 not to be necessary, and produces flickering.
13735 2011-03-20 Glenn Morris <rgm@gnu.org>
13737 * config.in: Remove file.
13739 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13741 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13742 are now in src/globals.h.
13743 (syms_of_minibuf): Remove spurious & from previous change.
13745 2011-03-20 Leo Liu <sdl.web@gmail.com>
13747 * minibuf.c (completing-read-function): New variable.
13748 (completing-read-default): Rename from completing-read.
13749 (completing-read): Call completing-read-function.
13751 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13753 * xfaces.c (Fx_load_color_file):
13754 Read color file from absolute filename (bug#8250).
13756 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13758 * makefile.w32-in: Update dependencies.
13760 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13762 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13769 (sigchld_handler): Now static.
13771 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13772 That way, the code declares only the vars that it needs.
13773 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13774 * s/cygwin.h (PTY_ITERATION): Likewise.
13775 * s/darwin.h (PTY_ITERATION): Likewise.

13782 (CONSTANTLIM): Remove; unused.
13783 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13784 Define only if needed.
13786 * unexelf.c (unexec): Name an expression,
13787 to avoid gcc -Wbad-function-cast warning.
13788 Use a different way to cause a compilation error if anyone uses
13789 n rather than nn, a way that does not involve shadowing.
13790 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13792 * deps.mk (unexalpha.o): Remove; unused.
13794 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13795 * unexec.h: New file.
13796 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13797 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13798 Depend on unexec.h.
13799 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13800 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13801 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
13802 Change as necessary to match prototype in unexec.h.
13804 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
13806 (back_comment, skip_chars): Mark vars as initialized.

13821 (font_sort_entities): Mark var as initialized.
13823 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
13825 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

13857 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13858 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13859 some of which prompt warnings from gcc -Wbad-function-cast.
13860 (Fformat_time_string, Fencode_time, Finsert_char):
13861 (Ftranslate_region_internal, Fformat):
13862 Rename or remove local vars to avoid shadowing.
13863 (Ftranslate_region_internal): Mark var as initialized.
13865 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13868 * lisp.h (eassert): Check that the argument compiles, even if
13869 ENABLE_CHECKING is not defined.
13871 * data.c (Findirect_variable): Name an expression, to avoid
13872 gcc -Wbad-function-cast warning.

13884 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13885 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13887 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13888 (GC_STRING_CHARS): Remove; not used.
13889 (Fmemory_limit): Cast sbrk's returned value to char *.
13891 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13892 avoids undefined behavior in theory.

13897 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13898 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13899 to use the following functions instead of these macros.
13900 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13901 EMACS_INT, since callers assume the returned value fits in int.
13902 (upcase1): Likewise, for UPCASE_TABLE.
13903 (uppercasep, lowercasep, upcase): New static inline functions.
13904 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13905 the race-condition problem in the old DOWNCASE.

13908 Rename locals to avoid shadowing.
13909 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13910 (regex_compile, re_search_2, re_match_2_internal):
13911 Remove unused local vars.
13912 (FREE_VAR): Rewrite so as not to use empty "else",
13913 which gcc can warn about.
13914 (regex_compile, re_match_2_internal): Mark locals as initialized.
13915 (RETALLOC_IF): Define only if needed.
13916 (WORDCHAR_P): Likewise. This one is never needed, but is used
13917 only in a comment talking about a compiler bug, so put inside
13918 the #if 0 of that comment.
13919 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13920 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13923 * search.c (boyer_moore): Rename locals to avoid shadowing.
13924 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
13925 (PREV_CHAR_BOUNDARY): Likewise.
13927 * search.c (simple_search): Remove unused var.
13929 * dired.c (compile_pattern): Move decl from here ...

13935 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13937 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13938 Rename locals to avoid shadowing.
13939 (Fvertical_motion): Mark locals as initialized.
13941 * casefiddle.c (casify_object, casify_region): Now static.
13942 (casify_region): Mark local as initialized.
13944 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13946 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13947 New macros, so that the caller can use some names other than
13948 gcpro1, gcpro2, etc.
13949 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13951 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13952 argument, for consistency with GCPRO2_VAR, etc: it is now the
13953 prefix of the variable, not the variable itself. All uses
13955 * dired.c (directory_files_internal, file_name_completion):
13956 Rename locals to avoid shadowing.
13958 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13959 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13960 dired.c's scmp function, had undefined behavior.
13961 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13962 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13963 * buffer.h: ... to here, because these macros use current_buffer,
13964 and the new implementation with inline functions needs to have
13965 current_buffer in scope now, rather than later when the macros
13967 (downcase, upcase1): New static inline functions.
13968 (DOWNCASE, UPCASE1): Reimplement using these functions.
13969 This avoids undefined behavior in expressions like
13970 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13971 from race conditions in accessing the global variables
13972 case_temp1 and case_temp2.
13973 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13974 * lisp.h (case_temp1, case_temp2): Remove their decls.
13975 * character.h (ASCII_CHAR_P): Move from here ...
13976 * lisp.h: ... to here, so that the inline functions mentioned
13977 above can use them.
