2011-07-05  Paul Eggert  <eggert@cs.ucla.edu>

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

220 221 222 223
	* eval.c (find_handler_clause): Remove parameters `sig' and `data',
	unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.  All callers changed.
	Also (re)move comments that are misplaced or no longer relevant.

2011-07-01  Paul Eggert  <eggert@cs.ucla.edu>

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

	The following patches are for when GLYPH_DEBUG && !XASSERT.
	* dispextern.h (trace_redisplay_p, dump_glyph_string):
	* dispnew.c (flush_stdout):
	* xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):

	Now static.
	(debug_method_add): Use va_list and vsprintf rather than relying
	on undefined behavior with wrong number of arguments.
	(dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
	Don't assume ptrdiff_t and EMACS_INT are the same width as int.
	In this code, it's OK to assume C99 behavior for ptrdiff_t formats
	since we're not interested in debugging glyphs with old libraries.
	* xfaces.c (cache_face): Move debugging code earlier; this pacifies
	GCC 4.6.0's static checking.

	Don't assume pid_t and time_t fit in unsigned long.
	(LOCK_PID_MAX): Remove; we now use more-reliable bounds.
	(current_lock_owner): Prefer signed type for sizes.
	Use memcpy, not strncpy, where memcpy is what is really wanted.
	Don't assume (via atoi) that time_t and pid_t fit in int.
	Check for time_t and/or pid_t out of range, e.g., via a network share.
	Don't alloca where an auto var works fine.

701 702 703 704
	* lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
	This didn't break anything, but it didn't help either.
	It's confusing to put a bogus integer in a place where the actual
	value does not matter.
705

711 712 713
	(struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
	We prefer signed types, and the value cannot exceed the EMACS_INT

714 715 716
	(XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,

	* fileio.c (Finsert_file_contents):
	* insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
	Remove the old (too-loose) buffer overflow checks.
	They weren't needed, since make_gap checks for buffer overflow.
	* insdel.c (make_gap_larger): Catch buffer overflows that were missed.
	The old code merely checked for Emacs fixnum overflow, and relied
	on undefined (wraparound) behavior.  The new code avoids undefined
	behavior, and also checks for ptrdiff_t and/or size_t overflow.

838
	* editfns.c (Finsert_char): Don't dump core with very negative counts.
839 840
	Tune.  Don't use wider integers than needed.  Don't use alloca.

859 860 861 862 863
	* fileio.c: Don't assume EMACS_INT fits in off_t.
	(emacs_lseek): New static function.
	(Finsert_file_contents, Fwrite_region): Use it.
	Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

864 865
	* fns.c (Fload_average): Don't assume 100 * load average fits in int.

866 867 868 869 870 871 872 873 874
	* fns.c: Don't overflow int when computing a list length.
	* fns.c (QUIT_COUNT_HEURISTIC): New constant.
	(Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
	truncation on 64-bit hosts.  Check for QUIT every
	QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
	faster and is responsive enough.
	(Flength): Report an error instead of overflowing an integer.
	(Fsafe_length): Return a float if the value is not representable
	as a fixnum.  This shouldn't happen except in contrived situations.
875
	(Fnthcdr, Fsort): Don't assume list length fits in int.
876
	(Fcopy_sequence): Don't assume vector length fits in int.

878 879 880 881 882 883 884
	* alloc.c: Check that resized vectors' lengths fit in fixnums.
	(header_size, word_size): New constants.
	(allocate_vectorlike): Don't check size overflow here.
	(allocate_vector): Check it here instead, since this is the only
	caller of allocate_vectorlike that could cause overflow.
	Check that the new vector's length is representable as a fixnum.

885 886 887 888 889 890
	* fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
	The previous code was bogus.  For example, next_almost_prime (32)
	returned 39, which is undesirable as it is a multiple of 3; and
	next_almost_prime (24) returned 25, which is a multiple of 5 so
	why was the code bothering to check for multiples of 7?

891 892
	* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

893 894
	* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

895 896 897 898
	Variadic C functions now count arguments with ptrdiff_t.
	This partly undoes my 2011-03-30 change, which replaced int with size_t.
	Back then I didn't know that the Emacs coding style prefers signed int.
	Also, in the meantime I found a few more instances where arguments
899 900
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.

	* lisp.h (struct Lisp_Subr.function.aMANY)
	(DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
	Arg counts are now ptrdiff_t, not size_t.
	All variadic functions and their callers changed accordingly.
	(struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
	* bytecode.c (exec_byte_code): Check maxdepth for overflow,
	to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
	* callint.c (Fcall_interactively): Check arg count for overflow,
	to avoid potential buffer overrun.  Use signed char, not 'int',
	for 'varies' array, so that we needn't bother to check its size
	calculation for overflow.
	* editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
	* eval.c (apply_lambda):
	* fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
	(struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.

958 959 960 961 962 963
	* fns.c (concat): Minor tuning based on overflow analysis.
	This doesn't fix any bugs.  Use int to hold character, instead
	of constantly refetching from Emacs object.  Use XFASTINT, not
	XINT, for value known to be a character.  Don't bother comparing

	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

972 973 974 975 976
	* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
	Without this fix, on a 64-bit host (aset S 0 4294967386) would
	incorrectly succeed when S was a string, because 4294967386 was
	truncated before it was used.

977 978 979 980
	* chartab.c (Fchar_table_range): Use CHARACTERP to check range.
	Otherwise, an out-of-range integer could cause undefined behavior
	on a 64-bit host.

981 982 983 984 985 986
	* composite.c: Use int, not EMACS_INT, for characters.
	(fill_gstring_body, composition_compute_stop_pos): Use int, not
	EMACS_INT, for values that are known to be in character range.
	This doesn't fix any bugs but is the usual style inside Emacs and
	may generate better code on 32-bit machines.

987 988 989 990 991 992 993 994
	Make sure a 64-bit char is never passed to ENCODE_CHAR.
	This is for reasons similar to the recent CHAR_STRING fix.

	* charset.h (ENCODE_CHAR): Verify that the character argument is no

	Make sure a 64-bit char is never passed to CHAR_STRING.
	Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
