[bpt/guile.git] / libguile / ChangeLog

2004-05-18  Marius Vollmer  <mvo@zagadka.de>

	* hashtab.c (rehash_after_gc): Bug fix: properly link the
	processed hashtables back into the weak_hashtables list.  Thanks
	to Bill Schottstaedt!

2004-05-16  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* eval.c (unmemoize_quote): New static function.

	(scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
	representation of 'quote' and '@slot-ref' to an improper list.
	This reduces execution time, the number of cells used to hold the
	memoized code, and thus also reduces garbage collection time.

	(scm_unmemocopy): Use unmemoize_quote for quote expressions.

	(SCM_CEVAL): Changed macro handling to also work with macros that
	return improper lists.  Added an assertion, that the code returned
	by a macro transformer will not lead to cycles in the memoized
	code.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	No functional change, just rearrangements of functions within the
	file.

	* eval.c (scm_ilookup, scm_unbound_variable_key,
	error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
	the definitions used for execution, since that's where they will
	belong to later.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* numbers.h (SCM_SLOPPY_FRACTIONP): Removed.  It was not used
	throughout guile, has not been part of an official release yet,
	and the concept of sloppy predicates has never been a good idea.

	(SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
	SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
	Simplified.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
	to make explicit what happens.

2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
	explicit what happens.

	* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
	SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.

2004-05-11  Marius Vollmer  <mvo@zagadka.de>

	* scmsigs.c (scm_sigaction_for_thread): Validate that the handler
	is indeed a procedure when it isn't a number.

2004-05-10  Marius Vollmer  <mvo@zagadka.de>

	Convert floating point numbers into strings with an arbitrary
	radix.  Thanks to Richard Todd!
	
	* numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
	fit.
	(fx): Removed.
	(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
	number_chars): New, to support variable radices.
	(idbl2str): Use above instead of the old base-10 only tables.
	(iflo2str): Pass on new RADIX argument to idbl2str.
	(scm_number_to_string): Pass radix to iflo2str.
	(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
	iflo2str.
	(scm_init_numbers): Call init_dblprec and init_fx_radix for all
	possible radices.

2004-05-10  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_logbit_p): Correction to test above the end of an
	inum.  Reported by Jan Konecny.

2004-05-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc.h (scm_t_cell): Fields are now of type SCM instead of
	scm_t_bits.  Updated all users.
	(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
	duplicating the code.
	(SCM_CELL_OBJECT_LOC): New.
	(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
	(SCM_CELL_WORD_LOC): Moved to "deprecated.h".

	* smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
	SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
	SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
	SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
	SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
	SCM_SMOB_OBJECT_3_LOC): New.
	* smob.c (scm_i_set_smob_flags): New function.

	* dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
	hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
	random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
	Use SCM_SMOB_* instead of SCM_CELL_* as appropriate.  Use
	SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
	zeroth word directly.  Use SCM_SMOB_PREDICATE as appropriate.

	* numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
	taking the address of SCM_CELL_WORD_1, the latter being no longer
	an lvalue.

	* variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
	of casting SCM_CELL_WORD_LOC.

2004-05-02  Kevin Ryde  <user42@zip.com.au>

	* eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
