	(ccl_driver): Use them to check for integer overflow when
	decoding a CCL program.  Many of the new checks are whether XINT (x)
	fits in int; it doesn't always, on 64-bit hosts.  The new version
	doesn't catch all possible integer overflows, but it's an

87 88 89
	* alloc.c (make_event_array): Use XINT, not XUINT.
	There's no need for unsigned here.

90 91 92 93
	* mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
	This follows up to the 2011-05-06 change that substituted uintptr_t
	for EMACS_INT.  This case wasn't caught back then.

	Rework Fformat to avoid integer overflow issues.
	* editfns.c: Include <float.h> unconditionally, as it's everywhere
	now (part of C89).  Include <verify.h>.
	(MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
	(pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
	(Fformat): Avoid the prepass trying to compute sizes; it was only
	approximate and thus did not catch overflow reliably.  Instead, walk
	through the format just once, formatting and computing sizes as we go,
	checking for integer overflow at every step, and allocating a larger
	buffer as needed.  Keep track separately whether the format is
	multibyte.  Keep only the most-recently calculated precision, rather
	than them all.  Record whether each argument has been converted to
	string.  Use EMACS_INT, not int, for byte and char and arg counts.
	Support field widths and precisions larger than INT_MAX.  Avoid
	sprintf's undefined behavior with conversion specifications such as %#d
	and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
	flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
	formatting out-of-range floating point numbers with int
	formats. (Bug#8668)

114 115
	* lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.

116 117 118 119 120 121 122 123 124
	* data.c: Avoid integer truncation in expressions involving floats.
	* data.c: Include <intprops.h>.
	(arith_driver): When there's an integer overflow in an expression
	involving floating point, convert the integers to floating point
	so that the resulting value does not suffer from catastrophic
	integer truncation.  For example, on a 64-bit host (* 4
	most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
	Do not rely on undefined behavior after integer overflow.

	merge count_size_as_multibyte, parse_str_to_multibyte
	* character.c, character.h (count_size_as_multibyte):
	Renamed from parse_str_to_multibyte; all uses changed.
	Check for integer overflow.
	* insdel.c, lisp.h (count_size_as_multibyte): Remove,
	since it's now a duplicate of the other.  This is more of
	a character than a buffer op, so better that it's in character.c.
	* fns.c, print.c: Adjust to above changes.

2011-05-27  Stefan Monnier  <monnier@iro.umontreal.ca>

	(Fx_clipboard_manager_save): Rename local to avoid shadowing.

145 146 147 148

	Fix some integer overflow issues, such as string length overflow.

317 318
	* insdel.c (count_size_as_multibyte): Check for string overflow.

319 320 321 322 323 324 325 326 327
	* character.c (lisp_string_width): Check for string overflow.
	Use EMACS_INT, not int, for string indexes and lengths; in
	particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
	the resulting string length overflows an EMACS_INT; instead,
	report a string overflow if no precision given.  When checking for
	precision exhaustion, use a check that cannot possibly have
	integer overflow.  (Bug#8675)
	* character.h (lisp_string_width): Adjust to new signature.

328 329 330 331 332 333
	* alloc.c (string_overflow): New function.
	(Fmake_string): Use it.  This doesn't change behavior, but saves
	a few bytes and will simplify future changes.
	* character.c (string_escape_byte8): Likewise.
	* lisp.h (string_overflow): New decl.

334 335 336
	Fixups, following up to the user-interface timestamp change.
	* nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
	for UI timestamps, instead of unsigned long.
337 338
	* msdos.c (mouse_get_pos): Likewise.
	* w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
339 340 341

	declaring it ourselves.  (Bug#8664)

342 343 344
	* dispextern.h (struct image): Don't assume time_t <= unsigned long.
	* image.c (clear_image_cache): Likewise.

345 346
	* term.c (term_mouse_position): Don't assume time_t wraparound.

	Be more systematic about user-interface timestamps.
	Before, the code sometimes used 'Time', sometimes 'unsigned long',
	and sometimes 'EMACS_UINT', to represent these timestamps.  This
	change causes it to use 'Time' uniformly, as that's what X uses.
	This makes the code easier to follow, and makes it easier to catch
	integer overflow bugs such as Bug#8664.
	* frame.c (Fmouse_position, Fmouse_pixel_position):
	Use Time, not unsigned long, for user-interface timestamps.
	* keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
	(button_down_time, make_lispy_position, make_lispy_movement): Likewise.
	* keyboard.h (last_event_timestamp): Likewise.
	* menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
	* menu.h (xmenu_show): Likewise.
	* term.c (term_mouse_position): Likewise.
	* termhooks.h (struct input_event.timestamp): Likewise.
	(struct terminal.mouse_position_hook): Likewise.
	* xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
	* xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
	* systime.h (Time): New decl.  Pull it in from <X11/X.h> if
	HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
	what it was before.
	* menu.h, termhooks.h: Include "systime.h", for Time.

370 371 372 373 374 375 376
	* keyboard.c (make_lispy_event): Fix problem in integer overflow.
	Don't assume that the difference between two unsigned long values
	can fit into an integer.  At this point, we know button_down_time
	<= event->timestamp, so the difference must be nonnegative, so
	there's no need to cast the result if double-click-time is
	nonnegative, as it should be; check that it's nonnegative, just in
	case.  This bug is triggered when events are more than 2**31 ms

381

382 383 384
	* xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
	that always fit in int.  Use a sentinel instead of a counter, to
	avoid a temp and to allay GCC's concerns about possible int overflow.
385 386
	* frame.h (struct frame): Use int for menu_bar_items_used

	* xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
	Before, the code was not consistent.  These values cannot exceed
	2**31 - 1 so there's no need to make them unsigned.
	(x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
	(x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
	(x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
	as modifiers.
	* xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.

401 402 403 404 405
	* lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
	(XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
	Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
	presumably because the widths might not match.

406 407
	* window.c (size_window): Avoid needless test at loop start.

	(Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
	child process will be redirected to a file specified with `:file'.

2011-05-07  Ben Key  <bkey76@gmail.com>

	* makefile.w32-in: The bootstrap-temacs rule now makes use of
	one of two shell specific rules, either bootstrap-temacs-CMD or
	bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
	to the previous implementation of the bootstrap-temacs rule.
	The bootstrap-temacs-CMD rule is similar to the previous
	implementation of the bootstrap-temacs rule except that it
	makes use of the ESC_CFLAGS variable instead of the CFLAGS
	variable.

	These changes, along with some changes to nt/configure.bat,
	nt/gmake.defs, and nt/nmake.defs, are required to extend my
	earlier fix to add support for --cflags and --ldflags options
	that include quotes so that it works whether make uses cmd or
	sh as the shell.

	a string.  Handle both cases.
	(Fdbus_call_method_asynchronously, Fdbus_register_signal)

	* dispnew.c (scrolling_window): Return 1 if we scrolled,
	to match comment at start of function.  This also removes a
	GCC warning about overflow in a 32+64-bit port.

535 536
	* lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

537 538 539
	* dbusbind.c: Do not use XPNTR on a value that may be an integer.
	Reported by Stefan Monnier in

540 541

	Use SYMBOLP-guarded XSYMBOL, not XPNTR.
542

543 544 545
	* lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
	(EMACS_UINTPTR): Likewise, with uintptr_t.

546 547 548 549
	* lisp.h: Prefer 64-bit EMACS_INT if available.
	(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
	on 32-bit hosts that have 64-bit int, so that they can access
	large files.
550 551
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.
552

553 554
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584
	Prefer intptr_t/uintptr_t for integers the same widths as pointers.
	This removes an assumption that EMACS_INT and long are the same
	width as pointers.  The assumption is true for Emacs porting targets
	now, but we want to make other targets possible.
	* lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
	(EMACS_INTPTR, EMACS_UINTPTR): New macros.
	In the rest of the code, change types of integers that hold casted
	pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
	replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
	(XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
	(XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
	No need to cast type when ORing.
	(XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
	* alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
	* doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
	assume EMACS_INT is the same width as char *.
	* gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
	(xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
	Remove no-longer-needed casts.
	(xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
	(xg_tool_bar_help_callback, xg_make_tool_item):
	Use EMACS_INTPTR to hold an integer
	that will be cast to void *; this can avoid a GCC warning
	if EMACS_INT is not the same width as void *.
	* menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
	* xdisp.c (display_echo_area_1, resize_mini_window_1):
	(current_message_1, set_message_1):
	Use a local to convert to proper width without a cast.
	* xmenu.c (dialog_selection_callback): Likewise.

585 586 587 588 589 590
	* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
	Also, don't assume VALBITS / RAND_BITS is less than 5,
	and don't rely on undefined behavior when shifting a 1 left into
	the sign bit.
	* lisp.h (get_random): Change signature to match.

591 592 593 594 595 596 597 598
	* lread.c (hash_string): Use size_t, not int, for hash computation.
	Normally we prefer signed values; but hashing is special, because
	it's better to use unsigned division on hash table sizes so that
	the remainder is nonnegative.  Also, size_t is the natural width
	for hashing into memory.  The previous code used 'int', which doesn't
	retain enough info to hash well into very large tables.
	(oblookup, oblookup_last_bucket_number, Funintern): Likewise.

599 600 601 602 603
	* dbusbind.c: Don't possibly lose pointer info when converting.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use XPNTR rather than XHASH, so that the high-order bits of
	the pointer aren't lost when converting through void *.

604 605
	* eval.c (Fautoload): Don't double-shift a pointer.

606 607
	* fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
844 845
	GCC 4.6.0 optimizes based on type-based alias analysis.
	For example, if b is of type struct buffer * and v of type struct
846 847 848 849 850
	Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
	!= &v->size, and therefore "v->size = 1; b->size = 2; return
	v->size;" must therefore return 1.  This assumption is incorrect
	for Emacs, since it type-puns struct Lisp_Vector * with many other
	types.  To fix this problem, this patch adds a new type struct

	* data.c (atof): Remove decl; no longer used or needed.
	(digit_to_number): Move to lread.c.
	(Fstring_to_number): Use new string_to_number function, to be
	consistent with how the Lisp reader treats infinities and NaNs.
	Do not assume that floating-point numbers represent EMACS_INT
	without losing information; this is not true on most 64-bit hosts.
	Avoid double-rounding errors, by insisting on integers when
	parsing non-base-10 numbers, as the documentation specifies.
	* lisp.h (string_to_number): New decl, replacing ...
	(isfloat_string): Remove.
906
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
907
	(read1): Do not accept +. and -. as integers; this
908 909 910 911 912 913 914
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report
	overflow for integer overflows unless the base is not 10 which
	means we have no simple and reliable way to continue.
	Break out the floating-point parsing into a new

	floating point numbers consistently with the Lisp reader.

	(digit_to_number): Move here from data.c.  Make it static inline.
916 917 918 919 920
	(E_CHAR, EXP_INT): Remove, replacing with ...
	(E_EXP): New macro, to solve the "1.0e+" problem mentioned below.

	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
921
	no longer mishandles examples like "1.0e+".  Use strtoumax,
922 923

	These assumptions hold on all porting targets that I know of, but
	they are not guaranteed, they're easy to remove, and removing them
	makes further changes easier.

	conversions.  Support %l conversion.  Don't assume an EMACS_INT
	argument for integer conversions and for %c.

	about invalid control letter, pass the character's codepoint, not
	a pointer to its multibyte form.  Improve display of the character
	in octal and display also its hex code.

	* character.c (char_string): Use %x to display the (unsigned)
	codepoint of an invalid character, to avoid displaying a bogus
	negative value.

	* font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
	`error', not SYMBOL_NAME itself.

	* coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
	character arguments to `error'.

	* charset.c (check_iso_charset_parameter): Fix incorrect argument
	to `error' in error message about FINAL_CHAR argument.  Make sure
	FINAL_CHAR is a character, and use %c when it is passed as
	argument to `error'.
