1999-08-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
	SCM_IM_HASH_DISPATCH.

	(scm_si_redfined, scm_si_hashsets): Moved.

	* objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
	flag which combines type and status info so that the class
	redefinition protocol has zero cost during normal execution.

1999-08-03  Gary Houston  <ghouston@easynet.co.uk>

	* ports.c (scm_puts): use ptob->write.
	* vports.c (scm_make_sfptob): set write proc in ptob.
	* strports.c (scm_make_stptob): set write proc in ptob.

1999-08-01  Jim Blandy  <jimb@savonarola.red-bean.com>

	* ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
	until we've verified that it is actually a port.  (Thanks to
	Lorentey Karoly.)

1999-07-31  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
	code, particularly an unnecessary test (len != size, where len ==
	size).  (Was this leftovers from debugging code, or have I missed
	something profound?)

	* hashtab.c: Bugfix: Don't declare s_hash_fold without storage
	size. (Thanks to James Dean Palmer.)

	* numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
	(Thanks to Lorentey Karoly.)

1999-07-30  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	New isym operations.

	* eval.h: Added prototypes for multi language support functions.

	* eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
	improper lists in the low-level representation, since that will
	cause a begin to be prepended at macro expansion.

	* eval.c (scm_cons_source): Version of cons which copies source
	properties from an existing cell.
	(scm_copy_tree, SCM_CEVAL): Use	scm_cons_source.

	* debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto

1998-10-25  Marius Vollmer  <mvo@zagadka.ping.de>

	Ported `internal defines' fix from SCM.  Original ChangeLog entry:

	    1998-07-09  Radey Shouman  <radey@colorage.com>

	    * eval.c (ceval_1): Modifications to allow rewriting of interal
	    DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
	    body of which it is the CAR is macro expanded by m_expand_body,
	    which rewrites internal DEFINE.

	    (m_expand_body): Added.

	    (m_macroexp1): Added argument to control error checking:
	    m_expand_body may speculatively expand forms in the wrong
	    environments.  Made argument number checks conditional on
	    RECKLESS.

	    (m_body): Added, error checks bodies and inserts the ISYM tokens.

	    (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
	    call m_body.

	    (m_cond): (m_case): (m_quote): Modified to avoid destructively
	    changing their argument forms.  Since m_expand_body
	    speculatively macro expands forms the process must be
	    reversible.

	    (m_ident_eqp): Fixed to use proper environment.

	    (renamed_ident): Added DEFER_INTS_EGC.

	    Added prototypes for static functions.

	* eval.c

	(undef_cell): New.
	
	(scm_lookupcar1, scm_lookupcar): Added CHECK argument.  When CHECK
	is false, do not produce an error for unbound variables, return a
	pointer to cell_undef instead.

	(EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.

	(scm_m_body): New.

	(scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
	destructively changing their argument forms.  Since m_expand_body
	speculatively macro expands forms the process must be reversible.

	(scm_m_lambda): Use scm_m_body instead of bodycheck.  Account for
	SCM_IM_LET introduced by named lets.

	(scm_m_letstar): Use scm_m_body instead of bodycheck.

	(scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
	scm_letrec.  scm_letrec1 does not check for a null binding and
	takes an additional argument to specify the ISYM of the body.  Use
	scm_m_body instead of bodycheck.

	(scm_m_let): Use scm_m_body instead of bodycheck.

	(scm_m_expand_body, scm_macroexp): New.

	(unmemocopy): Account for ISYMs introduced by scm_m_body.

	(ceval, deval): Call scm_m_expand_body.  Call scm_lookupcar with
	check=1.  Throw error for internal defined that have not been
	rewritten by scm_m_expand_body.

	* eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
	Removed prototype for SCM_APPLY.

	* tags.h: Added extern declaration of scm_isymnames.

1999-07-27  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.

	* lang.c: New file: Beginning of multi-language support.
	
	* init.c (scm_boot_guile_1): Added call to scm_init_lang ().

	* dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
	(scm_dynamic_wind): Added argument checking for the after guard so
	that we don't add garbage on the dynwind chain.
	(scm_swap_bindings): Added.

	* tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
	SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
	(scm_isymnames): New isyms for multi-language support.
	
 	* eval.c (scm_nil, scm_t): New symbols.
	(nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
	forms for multi-language support.

1999-07-25  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
	Added.
	Renamed functions in the random function library interface
	from scm_i_XXX --> scm_c_XXX.

1999-07-25  Gary Houston  <ghouston@easynet.co.uk>

	* ports.c (scm_putc): fix line-buffering.

1999-07-25  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
	scm_set_ptob_XXX --> scm_set_port_XXX.

1999-07-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* ports.c, ports.h (scm_make_port_type): New interface for
	creation of port types (replaces scm_newptob).  Just as for the
	smobs, we need to separate the internal representation of smob
	types from the interface, so that we easily can add new fields and
	rearrange things without caring about backward compatibility.
	This change was forced by the need in GOOPS to create classes
	representing port types.
	(scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
	scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
	scm_set_ptob_seek, scm_set_ptob_truncate,
	scm_set_ptob_input_waiting_p): New setters.
	(scm_newptob): Rewritten to use scm_make_port_type.  For backward
	compatibility.
	(scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
	(scm_prinport): Removed.
	(scm_port_print): Added.
	(scm_print_port_mode): Added.
	(void_port_ptob, print_void_port, close_void_port, noop0):
	Removed.  Removed #include "genio.h" Added #include "objects.h",
	#include "smobs.h"

	* fports.c (prinfport): Moved code from ports.c.
	(local_free): Added.
	(scm_fptob): Removed.  Instead use new interface.
	(scm_make_fptob): Added.  (Need to create basic ports in a
	specific order in ports.c.)
	
	* strports.c (scm_stptob, prinstpt, noop0): Removed
	(scm_make_stptob): Added.

	* vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
	(scm_make_sfport): Added.
	
	* filesys.c (scm_dir_print): Don't use the port printing code.
	Instead provide specific directory printer.
	
	* gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.

	* ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
	scm_ptob_descriptor.

	* smob.c (scm_smob_print): Handle non-existing type name nicely.
	Removed #include "genio.h"

	* objects.c (scm_make_port_classes): New function ptr.

1999-07-24  Gary Houston  <ghouston@easynet.co.uk>

	* gdbint.c (gdb_print, gdb_read): call scm_truncate_file.

	* ports.c (scm_truncate_file): renamed from scm_ftruncate.
	allow the 1st argument to be a fdes or filename as well as a
	port (as in the filesys.c version).

	* filesys.c (scm_truncate_file): removed.

1999-07-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* readline.c, readline.h: Removed.

	* objects.c, objects.h (scm_port_class): Added.
	(scm_class_of): Look up port class in scm_port_class.
	(SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
	SCM_INOUT_PCLASS_INDEX): Added.

	
	* Makefile.am: Removed genio.c, genio.x.

	* genio.c: Removed.

1999-07-23  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* init.c: Make sure that scm_post_boot_init_modules is called only
	once.  (Important when using a dumped image.; Thanks to Bernard
	Urban.)

1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>

	* guardians.c (scm_guardian_zombify): Separate scanning for
	zombies from marking the pairs of the free list.
	
	* guardians.c (scm_guardian_zombify): Don't set marks manually ---
	use the macros.  (Thanks to Michael Livshin.)

	* eval.c (scm_m_lambda): Let bodycheck check the body of the
	lambda.  Let your sins be purified by the blood of the lambda.
	(Thanks to Eric Hanchrow.)

	* net_db.c (h_errno): Don't declare this if it's #defined.  Eew.
	(Thanks to Valdis Kletnieks.)

	106
	107	* eval.c (ceval_1): Modifications to allow rewriting of interal

	214
	215	* ports.c, ports.h (scm_make_port_type): New interface for
	216	creation of port types (replaces scm_newptob). Just as for the
	217	smobs, we need to separate the internal representation of smob
	218	types from the interface, so that we easily can add new fields and
	219	rearrange things without caring about backward compatibility.
	220	This change was forced by the need in GOOPS to create classes
	221	representing port types.
	222	(scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
	223	scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
	224	scm_set_ptob_seek, scm_set_ptob_truncate,
	225	scm_set_ptob_input_waiting_p): New setters.
	226	(scm_newptob): Rewritten to use scm_make_port_type. For backward
	227	compatibility.
	228	(scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
	229	(scm_prinport): Removed.
	230	(scm_port_print): Added.
	231	(scm_print_port_mode): Added.
	232	(void_port_ptob, print_void_port, close_void_port, noop0):
	233	Removed. Removed #include "genio.h" Added #include "objects.h",

	235
	236	* fports.c (prinfport): Moved code from ports.c.
	237	(local_free): Added.
	238	(scm_fptob): Removed. Instead use new interface.
	239	(scm_make_fptob): Added. (Need to create basic ports in a
	240	specific order in ports.c.)
	241
	242	* strports.c (scm_stptob, prinstpt, noop0): Removed
	243	(scm_make_stptob): Added.
	244
	245	* vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
	246	(scm_make_sfport): Added.
	247
	248	* filesys.c (scm_dir_print): Don't use the port printing code.
	249	Instead provide specific directory printer.
	250
	251	* gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
	252
	253	* ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
	254	scm_ptob_descriptor.
	255

	257	Removed #include "genio.h"
	258
	259	* objects.c (scm_make_port_classes): New function ptr.
	260
69bc9ff3 GH	261	1999-07-24 Gary Houston <ghouston@easynet.co.uk>
	262
	263	* gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
	264
	265	* ports.c (scm_truncate_file): renamed from scm_ftruncate.
	266	allow the 1st argument to be a fdes or filename as well as a
	267	port (as in the filesys.c version).
	268
	269	* filesys.c (scm_truncate_file): removed.
	270

	287	* init.c: Make sure that scm_post_boot_init_modules is called only
	288	once. (Important when using a dumped image.; Thanks to Bernard
	289	Urban.)
