3 4 5 6
	* lisp.h (struct vectorlike_header, struct Lisp_Subr):  Signed sizes.
	Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
	well either way, and we prefer signed to unsigned.

7 8 9 10 11 12 13 14 15 16
	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.

	* textprop.c (text_property_stickiness):
	Obey Vtext_property_default_nonsticky.
	(syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
	* w32fns.c (syms_of_w32fns):
	* xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.

2011-07-04  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
	This is more efficient than Ffile_directory_p and avoids a minor race.

2011-07-04  Lars Magne Ingebrigtsen  <larsi@gnus.org>

32 33 34
	* buffer.c (Foverlay_put): Say what the return value is
	(bug#7835).

35 36 37

	is a directory before asking whether to use the file name
	(bug#7564).
38 39
	(barf_or_query_if_file_exists): Make the "File is a directory"
	error be more correct.

41 42 43 44

2011-07-04  Paul Eggert  <eggert@cs.ucla.edu>

	* gnutls.c (Fgnutls_boot): Don't mention :verify-error.
	(syms_of_gnutls): Remove duplicate DEFSYM for
	Qgnutls_bootprop_verify_hostname_error, an error for
	Qgnutls_bootprop_verify_error (which is no longer used).

57 58 59 60
	* 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):
	Mark as externally visible.
	* dispnew.c (check_window_matrix_pointers): Now static.
	* dispnew.c (window_to_frame_vpos):
	* xfns.c (unwind_create_frame):
	* xterm.c (x_check_font): Remove unused local.
	* scroll.c (CHECK_BOUNDS):
	* xfaces.c (cache_fache): Rename local to avoid shadowing.
	* xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
	* xdisp.c (check_window_end): Now a no-op if !XASSERTS.
	(debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
	(debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
	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.

801
	* floatfns.c (Fexpt):
802 803
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

804 805 806
	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

807 808
	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

809 810 811 812 813
	* 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.

814 815 816 817
	* 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.

818 819 820 821 822 823
	* 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.

824 825 826 827 828 829 830 831
	Make sure a 64-bit char is never passed to ENCODE_CHAR.
	This is for reasons similar to the recent CHAR_STRING fix.
	* charset.c (Fencode_char): Check that character arg is actually
	a character.  Pass an int to ENCODE_CHAR.
	* charset.h (ENCODE_CHAR): Verify that the character argument is no
	wider than 'int', as a compile-time check to prevent future regressions
	in this area.

832
	* character.c (char_string): Remove unnecessary casts.
833 834 835 836 837 838 839 840 841 842

	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,
	by silently ignoring the top 32 bits, allowing some values
	that were far too large to be valid characters.
	* character.h: Include <verify.h>.
	(CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
	arguments are no wider than unsigned, as a compile-time check
	to prevent future regressions in this area.

853 854 855 856 857
	Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.

	(n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)

	The definition here is exact; the one in lisp.h was approximate.
	(allocate_string_data): Check for string overflow.  This catches
	some instances we weren't catching before.  Also, it catches
	size_t overflow on (unusual) hosts where SIZE_MAX <= min
