	Do not create empty overlays with the evaporate property (Bug#9642).
4 5 6 7 8 9
	* buffer.c (Fmove_overlay): Reinstate the earlier fix for
	Bug#9642, but explicitly check that the buffer the overlay would
	be moved to is live and rearrange lines to make sure that errors
	will not put the overlay in an inconsistent state.
	(Fdelete_overlay): Cosmetics.

	* w32term.c (my_bring_window_to_top): New function.
	(x_raise_frame): Use handle returned by DeferWindowPos, which
	could be different from the original one.  Call
	my_bring_window_to_top instead of my_set_foreground_window.
	(Bug#11513)

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

	* w32term.h (WM_EMACS_BRINGTOTOP): New message.
	(WM_EMACS_END): Increase by one.

2012-05-28  Paul Eggert  <eggert@cs.ucla.edu>

	* bidi.c (bidi_mirror_char): Put eassert before conversion to int.
	This avoids undefined behavior that might cause the eassert
	to not catch an out-of-range value.

46 47 48 49
	* lisp.h [REL_ALLOC]: Omit duplicate prototypes.
	Only r_alloc_inhibit_buffer_relocation needed to be added;
	the others were already declared.

50 51 52 53 54
	* bidi.c (bidi_mirror_char): Don't possibly truncate the integer
	before checking whether it's out of range.  Put the check inside
	eassert.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

	* lisp.h [REL_ALLOC]: Add prototypes for external functions
	defined on ralloc.c.

	* buffer.c [REL_ALLOC]: Remove prototypes of
	r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
	they are now on lisp.h.

	* ralloc.c (r_alloc_inhibit_buffer_relocation): New function.

	* search.c (search_buffer): Use it to inhibit relocation of buffer
	text while re_search_2 is doing its job, because re_search_2 is
	passed C pointers to buffer text.  (Bug#11519)

75 76 77
	* msdos.c (internal_terminal_init) <Vwindow_system_version>:
	Update value to 24.

78 79 80 81 82 83 84 85
	* xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
	state after an additional call to move_it_in_display_line_to, keep
	the values of it->max_ascent and it->max_descent found for the
	entire line.
	(pos_visible_p): Revert the comparison against bottom_y to what it
	was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
	(Bug#11464)

2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>

	Fix coding-related core dumps with gcc -ftrapv.
	The code was computing A - B, where A and B are pointers, and B is
	random garbage.  This can lead to core dumps on platforms that
	have special pointer registers, and it also leads to core dumps on
	x86-64 when compiled with gcc -ftrapv.  The fix is to compute
	A - B only when B is initialized properly.
	* coding.c (coding_set_source, coding_set_destination): Return void.
	(coding_change_source, coding_change_destinations): New functions,
	with the old behaviors of coding_set_source and coding_set_destination.
	All callers that need an offset changed to use these new functions.

99 100 101 102
2012-05-26  Glenn Morris  <rgm@gnu.org>

	* nsterm.m (ns_init_paths): Don't mess with INFOPATH.  (Bug#2791)

106 107 108 109 110 111 112 113
	* xdisp.c (draw_row_with_mouse_face): Call
	tty_draw_row_with_mouse_face for WINDOWSNT as well.

	* w32console.c: Include window.h.
	(w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face): New
	functions.
	(initialize_w32_display): Initialize mouse-highlight data.

114 115 116 117 118 119 120
	* w32inevt.c: Include termchar.h and window.h.
	(do_mouse_event): Support mouse-autoselect-window.  When the mouse
	moves, call note_mouse_highlight.  If help_echo changed, call
	gen_help_event to produce help-echo message in the echo area.
	Call clear_mouse_face if mouse_face_hidden is set in the mouse
	highlight info.

121 122 123 124 125
2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>

	* lread.c (read1): Simplify slightly to avoid an overflow warning
	with GCC 4.7.0 on x86-64.

	(validate_region): Omit unnecessary test for b <= e,
	since that's guaranteed by the previous test.
170 171 172 173 174 175 176
	(adjust_overlays_for_delete): Avoid pos + length overflow.
	(Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
	(report_overlay_modification):
	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
	(Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
	Omit pointer cast, which isn't needed anyway, and doesn't work
	after the EMACS_INT -> ptrdiff_t change.
177
	(Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
178 179 180 181
	* buffer.h: Adjust decls to match defn changes elsewhere.
	(struct buffer_text, struct buffer):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	Use EMACS_INT, not int, where int might not be wide enough.
182 183 184 185 186 187
	* bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
	not int, to avoid needless 32-bit limit on 64-bit hosts.
	(exec_byte_code): Use tighter memory-full test, one that checks
	for alloca overflow.  Don't compute the address of the object just
	before an array, as that's not portable.  Use EMACS_INT, not
	ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.

	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
	* callproc.c (call_process_kill, Fcall_process):
	Don't assume pid_t fits into an Emacs fixnum.

	Don't assume pid_t fits into int.
	(call_process_cleanup, Fcall_process, delete_temp_file)

	Use int, not EMACS_INT, where int will do.
	* casefiddle.c (casify_object, casify_region, operate_on_word)
	(Fupcase_word, Fdowncase_word, Fcapitalize_word):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	(casify_object): Avoid integer overflow when overallocating buffer.
	* casetab.c (set_identity, shuffle): Prefer int to unsigned when
204
	either works.  Use lint_assume to convince GCC 4.6.1 that it's OK.

	(resolve_symbol_ccl_program): Check that vector header is in range.
	Always copy the vector, so that we can check its contents reliably
	now rather than having to recheck each instruction as it's being
	executed.  Check that vector words fit in 'int'.
	(ccl_get_compiled_code, Fregister_ccl_program)
	(Fregister_code_conversion_map): Use ptrdiff_t, not int, for
	program indexes, to avoid needless 32-bit limit on 64-bit hosts.
	(Fccl_execute, Fccl_execute_on_string): Check that initial reg
	contents are in range.
	(Fccl_execute_on_string): Check that status is in range.

	avoid mishandling large integers.

	* charset.c (load_charset_map_from_file, find_charsets_in_text)
	(Ffind_charset_region):
	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

246 247 248 249 250 251 252 253 254 255 256 257
	Don't rely on undefined behavior with signed left shift overflow.
	Don't assume unsigned int fits into fixnum, or that fixnum fits
	into unsigned int.  Don't require max_code to be a valid fixnum;
	that's not true for gb10830 4-byte on a 32-bit host.  Allow
	invalid_code to be a cons, for the same reason.  Require code_offset
	to be a character.  Avoid int overflow if max_char is close
	to INT_MAX.
	(CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
	this is intended anyway and avoids some undefined behavior.
	(load_charset_map): Pass unsigned, not int, as 2nd arg of
	INDEX_TO_CODE_POINT, as that's what it expects.
	(Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
258 259 260 261 262 263 264
	* charset.h (DECODE_CHAR): Return int, not unsigned;
	this is what was intended anyway, and it avoids undefined behavior.
	(CHARSET_OFFSET): Remove unused macro, instead of fixing its
	integer-overflow issues.
	(ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
	Formerly, it returned EMACS_INT on 64-bit hosts in the common case
	where the argument is EMACS_INT, and this behavior is not intended.
265 266 267 268 269 270
	* chartab.c (Fmake_char_table, Fset_char_table_range)
	(uniprop_get_decoder, uniprop_get_encoder):
	Don't assume fixnum fits in int.
	* cmds.c (move_point): New function, that does the gist of
	Fforward_char and Fbackward_char, but does so while checking
	for integer overflow more accurately.
271
	(Fforward_char, Fbackward_char): Use it.
272 273 274 275 276 277
	(Fforward_line, Fend_of_line, internal_self_insert)
	(internal_self_insert):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	Fix a FIXME, by checking for integer overflow when calculating
	target_clm and actual_clm.

	proceed with what's on the stack, instead of returning zero.

	* xdisp.c (handle_single_display_spec): Return 1 for left-margin
	and right-margin display specs even if the spec is invalid or we
	are on a TTY, and thus unable to display on the fringes.  That's
	because the text with the property will not be displayed anyway,
	so we need to signal to the caller that this is a "replacing"
	display spec.  This fixes display when the spec is invalid or we
	are on a TTY.

	Untag more efficiently if USE_LSB_TAG.
	This is based on a proposal by YAMAMOTO Mitsuharu in
	<http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
	For an admittedly artificial (nth 8000 longlist) benchmark on
	Fedora 15 x86-64, this yields a 25% CPU speedup.  Also, it shrinks
	Emacs's overall text size by 1%.
	* lisp.h (XUNTAG): New macro.
	(XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
	(XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
	(XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
	* eval.c (Fautoload):
	* font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):

1170 1171 1172 1173 1174 1175 1176 1177
	Port recent dbusbind.c changes to 32-bit --with-wide-int.
	* dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
	Remove unportable assumptions about print widths of types like
	dbus_uint32_t.
	(xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
	intptr_t when converting between pointer and integer, to avoid GCC
	warnings about wrong width.

	* w32proc.c (new_child): Force Windows to reserve only 64KB of
	stack for each reader_thread, instead of defaulting to 8MB
	determined by the linker.  This avoids failures in creating
	subprocesses on Windows 7, see the discussion in this thread:
	http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.

	Fix up display of the *Minibuf-0* buffer in the mini window.
	* keyboard.c (read_char): Don't clear the echo area if there's no
	message to clear.
	* xdisp.c (redisplay_internal): Redisplay the mini window (with the
1192
	contents of *Minibuf-0*) if there's no message displayed in its stead.

2012-05-03  Paul Eggert  <eggert@cs.ucla.edu>

	Do not limit current-time-string to years 1000..9999.
	* editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
	(Fcurrent_time_string): Support any year that is supported by the
	underlying localtime representation.  Don't use asctime, as it
	has undefined behavior for years outside the range -999..9999.

1225 1226 1227 1228 1229 1230 1231 1232 1233 1234 1235 1236 1237
2012-05-02  Paul Eggert  <eggert@cs.ucla.edu>

	Fix race conditions involving setenv, gmtime, localtime, asctime.
	Without this fix, interrupts could mess up code that uses these
	nonreentrant functions, since setting TZ invalidates existing
	tm_zone or tzname values, and since most of these functions return
	pointers to static storage.
	* editfns.c (format_time_string, Fdecode_time, Fencode_time)
	(Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
	Grow the critical sections to include not just invoking
	localtime/gmtime, but also accessing these functions' results
	including their tm_zone values if any, and any related TZ setting.
	(format_time_string): Last arg is now struct tm *, not struct tm **,
1238 1239
	so that the struct tm is saved in the critical section.
	All callers changed.  Simplify allocation of initial buffer, partly
1240 1241 1242
	motivated by the fact that memory allocation needs to be outside
	the critical section.

	* xdisp.c (pos_visible_p): If already at a newline from the
	display string before the 'while' loop, don't walk back the glyphs
	from it3.glyph_row.  Solves assertion violation when the display
	string begins with a newline (egg.el).  (Bug#11367)

	and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
	All were removed before 23.1.

1276 1277 1278
	* dispnew.c: Remove HAVE_LIBNCURSES test;
	it is always true on relevant platforms.

1279 1280 1281

	Do not avoid creating empty evaporating overlays (Bug#9642).
	* buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
	That is, do not delete an evaporating overlay if it becomes
	empty after its bounds are adjusted to fit within its buffer.
	This fix caused other problems, and I'm reverting it until we get
	to the bottom of them.
