(scm_make_regexp): Free rx on error, to avoid memory leak.

[bpt/guile.git] / libguile / ChangeLog

2004-07-10  Kevin Ryde  <user42@zip.com.au>

	* hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
	than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
	such a size causes divide-by-zeros in scm_hasher.

2004-07-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
	Rewritten using the same logic as scm_to_signed_integer and
	scm_to_unsigned_integer, respectively, which is better(tm).  Also,
	use CHAR_BIT instead of hardcoding 8.
	(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
	SCM_I_LLONG_MIN etc. instead.
	
	* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
	SCM_I_MAKINUM and changed all uses.
	* deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.

	* gen-scmconfig.c: Instead of hard-coding the numbers, compute
	them by assuming twos-complement.

2004-07-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
	configure now produces.
	* gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
	definitions, giving the limits of the integer types defined by
	Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
	LLONG_MIN or LONG_LONG_MIN is hard to get at.

	* numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
	SHORT_MIN.
	(scm_to_size_t): Use SIZE_MAX instead of cooking our own.
	(scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
	scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
	scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,
	scm_from_long_long, scm_from_ulong_long, scm_from_int8,
	scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
	scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
	scm_from_uintmax): New.
	
2004-07-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* tags.h (scm_is_eq): New.

	* deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
	SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
	"deprecated.h".  Replaced all uses with scm_is_false, scm_is_true,
	scm_from_bool, and scm_is_bool, respectively.

	* boolean.h (scm_is_bool): Fix bug in prototype.
	(scm_from_bool): The argument is "x" not "f", stupid.

	* boolean.c (scm_is_bool): Fix typo.

	* numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
	scm_is_unsigned_integer, scm_to_signed_integer,
	scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,
	scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong,
	scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar,
	scm_from_char, scm_from_short, scm_from_ushort, scm_from_int,
	scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t,
	scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
	New.
	
2004-07-05  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
	scm_to_bool): New.

2004-06-27  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* backtrace.c (display_expression, display_frame): Call
	scm_i_unmemoize_expr for unmemoizing a memoized object holding a
	single memoized expression.

	* debug.c (memoized_print): Don't try to unmemoize the memoized
	object, since we can't know whether it holds a single expression
	or a body.

	(scm_mem_to_proc): Removed check for lambda expression, since it
	was moot anyway.  Whoever uses these functions for debugging
	purposes should know what they do: Creating invalid memoized code
	will cause crashes, independent of whether this check is present
	or not.

	(scm_proc_to_mem): Take the closure's code as it is and don't
	append a SCM_IM_LAMBDA isym.  To allow easier debugging, the
	memoized code should not be modified.

	* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
	scm_unmemoize from public use, but made scm_i_unmemoize_expr
	available as a guile internal function instead.  However,
	scm_i_unmemoize_expr will only work on memoized objects that hold
	a single memoized expression.  It won't work with bodies.

	* debug.c (scm_procedure_source), macros.c (macro_print), print.c
	(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
	i. e. a list of expressions.

	* eval.c (unmemoize_exprs): Drop internal body markers from the
	output during unmemoization.

	* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
	scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
	but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
	as guile internal functions instead.  scm_i_unmemoize_expr will
	only work on a single memoized expression, while
	scm_i_unmemocopy_body will only work on bodies.

2004-06-21  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (unmemoize_exprs): Handle semi-memoized code.

	(scm_cons_source, scm_primitive_eval): Prefer higher level
	predicate SCM_FALSEP over SCM_IMP.

2004-06-15  Rob Browning  <rlb@defaultvalue.org>

	* script.c (scm_shell_usage): minor phrasing change.

	* gc_os_dep.c: update ifdefery for macosx.
	(scm_get_stack_base): separate result initialization from
	declaration to slience warnings with macosx and hp-ux using gcc
