Optimize 'string-hash'.

[bpt/guile.git] / libguile / ChangeLog-1996-1999

1999-12-28  Gary Houston  <ghouston@arglist.com>

	* posix.c (scm_waitpid): move the HAVE_WAITPID test out of the
	procedure body, so that the procedure is left undefined if waitpid
	is not available.  previously in this case the procedure was
	defined but would raise a system-error when called, which is
	pointless.  I intend to make the same change for other procedures
	and deprecate SCM_SYSMISSING and scm_sysmissing.
	
1999-12-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* feature.c (s_scm_add_hook_x): Call scm_wrong_type_arg instead of
	scm_misc_error when add-hook! is passed a procedure of wring
	arity.  (Thanks to Greg Harvey.)

1999-12-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* macros.c (scm_make_synt): Use scm_make_subr_opt to make the
	transformer subr.  (Thanks to Bill Schottstaedt.)

1999-12-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR
	setting struct table class.

Sun Dec 19 10:22:34 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* threads.c, mit-pthreads.c, list.c, coop.c:  Remove K&R
	prototypes; just use ANSI C prototypes.  I'm not sure how
	mit-pthreads.c ever compiled -- it still doesn't for me, but the
	normal make procedure does not try to build it anyway (even
	--with-threads I get the other threads code building) so I'm not
	too worried about it.

Sat Dec 18 16:58:34 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of
	SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP.  (SCM_CONSP) Define this
	in terms of SCM_SLOPPY_NCONSP instead of repeating the
	expression.

	* symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
	define latter in terms of sloppy variant.

	* strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
	define latter in terms of sloppy variant.

	* scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
 	out the commonality of the various basic SCM_VALIDATE_foop
 	macros. Use SCM_MAKE_VALIDATE macro where possible.  Fix
 	SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
 	coercion to an integer which is more advanced than desired and
 	SCM_NUM2ULONG provides that functionality.  Use SCM_ASSERT_RANGE
 	appropriately for the various _MIN, _MAX, _RANGE macros.  Drop
 	some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
 	SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
 	part of its SCM_CONSP test).

	* socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
	SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS. 

Sat Dec 18 15:33:05 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* dynl.c: Added #include "scm_validate.h"

Sat Dec 18 15:22:10 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use
 	SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of
	scm_num2long; SCM_WTA instead of scm_wta.  Only done for when
	FUNC_NAME was used as an argument of the macro and the formal
	argument name was the explicit argument in the old function call.
	These were just missed in my first pass of changes.

1999-12-18  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* guile-doc-snarf.in (filename): Strip path to source dir before
	touching the .x-files.

1999-12-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP.

	* eval.c (SCM_CEVAL): Removed check for unbound slot in
	SCM_IM_SLOT_REF.  (This is now handled in a smarter way in GOOPS.)

1999-12-17  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
	(SCM_ECONSP): Version which doesn't mix && and || without
	parenthesis.
	(SCM_NECONSP): Bugfree version.

Fri Dec 17 12:09:11 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
	SCM_NIMP test integrated into an || clause that I'd missed before
	and was causing a segfault in the regression tests.

	* symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not 
	(char *);  fixes a problem reported by the regression test
	ports.test.

	* ports.c: Fixed a couple of arg/number mismatches in
	SCM_VALIDATE_ macros.

	Now passes the (not-comprehensive) guile-modules test-suite again!

Thu Dec 16 12:41:22 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* coop-threads.c: Remove K&R function headers.

	* scm_validate.h: Added SCM_VALIDATE_THREAD.

	* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
	that SCM_FOOP macros all now include SCM_NIMP in their expansion.
	This simplifies lots of code, making it far more readable.

Wed Dec 15 19:45:14 1999  Greg J. Badros  <gjb@cs.washington.edu>

 	* *.h: Use SCM_NIMP(X) && in all the FOOP macros.

	* *.[ch]: Use do { ... } while (0) idiom in macros that expanded
 	to a bare block.

Tue Dec 14 10:53:14 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* snarf.h: Put SCM_PROC and SCM_PROC1 back in for
	backward-compatibility of packages that use Guile.  Internally
	Guile should not use them, though.  (Maybe enforce this with a new 
	-DBUILDING_GUILE compile-time flag?).

Tue Dec 14 09:41:01 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* backtrace.c (scm_set_print_params_x): Renamed from
	set_print_params_x.

	* guile-doc-snarf.in: Use guile-snarf.awk, not
	guile-doc-snarf.awk.  Pass the basename of $filename 

	* load.h: Added prototypes for scm_sys_library_dir,
	scm_sys_site_dir.

	* load.c (scm_sys_library_dir, scm_sys_site_dir):  Added these
	functions, and took out the old scm_library_dir, scm_site_dir,
	scm_pkgdata_dir.  Now the primitives are %package-data-dir
	(already existed), %library-dir, and %site-dir.

	* debug.c: Use SCM_MISC_ERROR when possible instead of using
	s_scm_* in a scm_misc_error() call.

	* Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk.  Make 
	using guile-doc-snarf send stdout to $@ to create the .x file like 
	guile-snarf does.

	* guile-snarf.awk.in: Added.

	* guile-doc-snarf.awk.in: Removed (sorry to back out a recent
	commit; if we're going to switch to guile-snarf I figure it makes
	sense to get this right now-- I'd already had the change in my
	working copy when the below commit happened).

1999-12-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* guile-doc-snarf.awk: Removed.

	* guile-doc-snarf.awk.in: Added.
	
	* ports.c (s_scm_pt_member): Fixed validation.

	* guile-doc-snarf.in (filename): Use basename in order to strip
	away path.

	* debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
	semicolon.
	(scm_memcons, scm_memcons, mem_to_proc): Renamed function name
	strings to new form.

	* backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.

	* tags.h (SCM_UNBOUND): New iflag which is needed for some time to
	mark the unboundness of a GOOPS slot.  (Added now in order to
	correct a oversight.  Should probably be removed again and
	replaced with SCM_UNDEFINED when the corresponding code in GOOPS
	is rewritten.)

	* print.c (scm_isymnames): Added printed representation for
	SCM_UNBOUND.

	* eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
	SCM_IM_SLOT_REF.

Mon Dec 13 17:23:22 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* strings.c: Fixed mistaken default value in
	scm_make_shared_substring; thanks Eric Moore!

Mon Dec 13 16:29:13 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
	replacement for docstrings.  Fixes problem Ryan Yeske observed
	with using mawk on his system.  Thanks Ryan!

Mon Dec 13 13:30:06 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* guile-doc-snarf.in: Do not echo to stdout since the output now
	gets stuck directly in the files instead of redirected from
	stdout. 

	* guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
	Yeske. Use print instead of printf to prime the .x file since
	AIX's cpp has problems with #include-ing empty files (according to 
	the old guile-snarf.in file).
	
Sun Dec 12 19:39:00 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
 	GUILE_PROC1.  Build guile-procedures.txt, and add that file to
 	pkgdata_DATA.

	* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
	primitives.

	* guile-doc-snarf.awk: Drop trailing space when no arguments:
	e.g., "(foo )" is now "(foo)".

	* *.c, alist.c: moved all the documentation for primitives from
 	guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
  	This leaves about half of the primitives undocumented.  Also, all
 	the markup is currently still texinfo.  I don't have a problem
 	with texinfo per se, but the markup is not very descriptive or
 	accurate.

Sun Dec 12 16:50:26 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
 	SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
 	argument mismatches (along with the FUNC_NAME macro checking) by a
 	static tool that runs directly over the .c files.

	* snarf.h: Handle SCM_REGISTER_PROC better when snarfing.  The
	docstring is still missing from the .doc file;  it just gives the
	name of the C function that gets called instead.

	* guile-doc-snarf.awk: Be sure to touch the output files to help
	make out.  Also handle SCM_REGISTER_PROC better, and change the
	output format slightly.

Sun Dec 12 15:33:40 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
	guile-doc-snarf script.

	* guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
	extraction system.  Builds foo.x, foo.doc from foo.{c,cc}.
	There are dependencies between these files and snarf.h.  This
	replaces guile-snarf.

	* guile-snarf.in: Drop everything after $$$ for the new snarf.h
	macros.  This is obsoleted by guile-doc-snarf, but kept here for
	now for good measure.

	* Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
	bin_SCRIPTS.  Added .doc to SUFFIXES, and give rule for creating
	.doc files to use guile-doc-snarf.  Update the rule for creating
	.x files to use guile-doc-snarf.

Sun Dec 12 12:31:38 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* *.c: Finish replacing K&R style prototypes with ANSI C
	prototypes.

	* eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
	char *.  ANSI prototypes caught this.

	* strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
	that I missed.

	* scm_validate.h: Use SCM_BOOLP for validating bools.  Do not
	expand macros if SCM_DOCSTRING_SNARF.

Sun Dec 12 11:23:22 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
	SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
	SCM_BOOL_T).

Sun Dec 12 11:08:51 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
	from scm_validate.h.

	* scm_validate.h: Moved above out into boolean.h, fix typo in
	SCM_VALIDATE_NIM macro.

Sun Dec 12 10:29:12 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
 	(none of the other validate macros have the trailing P).

Sun Dec 12 10:07:29 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* scm_validate.h: Added the FSF copyright to the top.

	* strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of 
	SCM_ASSERT w/ SCM_OUT_OF_RANGE.

Sat Dec 11 18:34:12 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* Makefile.am: Added scm_validate.h to modinclude_HEADERS.

	* *.c: Pervasive software-engineering-motivated rewrite of
 	function headers and argument checking.  Switched SCM_PROC,
 	SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
 	later, but was useful to keep old versions around while migrate)
 	that has docstrings and argument lists embedded in the GUILE_PROC
 	macro invocations that expand into a function header.  Use lots of
 	new SCM_VALIDATE_* macros to simplify error checking and reduce
 	tons of redundancy.  This is very similar to what I did for Scwm.

	Note that none of the extraction of the docstrings, nor software
 	engineering checks of Scwm is yet added to Guile.  I'll work on
 	that tomorrow, I expect.

	* chars.c: Added docstrings for the primitives defined in here.

	* snarf.h:  Added GUILE_PROC, GUILE_PROC1.  Added
	SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
	still remains for now.  Changed naming convention for the s_foo
	string name of the primitive to be s_scm_foo for ease of use with
	the macro.

	* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
	argument checking through guile.  Maybe some of these should be
	folded into the header file for the types they check, but for now
	it was easiest to just stick them all in one place.

1999-12-10  Greg Harvey  <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)

	* smob.c (scm_smob_prehistory): initialize allocated smob

	* tags.h: new tag: scm_tc16_allocated

	* gc.c (scm_gc_for_newcell): set the car of the new cell
	to scm_tc16_allocated
	* pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
	(scm_gc_mark): mark allocated cells.

1999-12-09  Greg J. Badros  <gjb@cs.washington.edu>

	* strports.h, strports.c (scm_eval_0str): Fix constness.  Some
	thanks to Dirk Hermann.

	* gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
	gh_eval_str_with_standard_handler,
	gh_eval_str_with_stack_saving_handler): Fix constness.  Some
	thanks to Dirk Hermann.

	* gh_data.c (gh_str02scm): Fix constness.

	* gh.h: Fix constness of prototypes for the above.

	* vectors.c: Include "unif.h" to avoid a warning about missing
	prototype for scm_uniform_element_size().

1999-12-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
	Turned into primitive generics.	

1999-12-04  Gary Houston  <ghouston@freewire.co.uk>

	* ports.c (scm_port_closed_p): new procedure, implements 
	"port-closed?" suggested by Bernard Urban.
	ports.h: added prototype, removed the SCM_P macros.

1999-11-30  Gary Houston  <ghouston@freewire.co.uk>

	* unif.h: added some comments, removed the SCM_P macros.

1999-11-29  Gary Houston  <ghouston@freewire.co.uk>

	* vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
	(thanks to Daniel Skarda).

1999-11-22  Jim Blandy  <jimb@savonarola.red-bean.com>

	* gscm.c, gscm.h: Deleted.  They were unused.

1999-11-20  Gary Houston  <ghouston@freewire.co.uk>

	* unif.c (scm_list_to_uniform_array): call 
	scm_dimensions_to_uniform_array with a third argument of 
	SCM_UNDEFINED instead of SCM_EOL.

1999-11-19  Gary Houston  <ghouston@freewire.co.uk>

	* the following changes allow guile to be built with the array
	"module" omitted.  some of this stuff is just tc7 type support,
	which wouldn't be needed if uniform array types were converted
	to smobs.
	
	* tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
	HAVE_ARRAYS.
	(scm_tag): don't check array types unless HAVE_ARRAYS.

	* sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
	remove the unused array types.
	* (scm_stable_sort, scm_sort): don't support vectors if not
	HAVE_ARRAYS.  a bit excessive.

	* random.c (vector_scale, vector_sum_squares, 
	scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
	scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.

	* gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
	gh_longs2ivect,	gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
	gh_uniform_vector_length, gh_uniform_vector_ref):
	don't define unless HAVE_ARRAYS.
	(gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
	gh_scm2doubles):
	don't check vector types if not HAVE_ARRAYS.

	* eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
	gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
	don't support the array types unless HAVE_ARRAYS is defined.

	* tags.h: make nine tc7 types conditional on HAVE_ARRAYS.

	* read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is 
	defined (this should use read-hash-extend).

	* ramap.c, unif.c: don't check whether ARRAYS is defined.

	* vectors.c (scm_vector_set_length_x): moved here from unif.c.  call
	scm_uniform_element_size if HAVE_ARRAYS.
	vectors.h: prototype too.

	* unif.c (scm_uniform_element_size): new procedure.

	* init.c (scm_boot_guile_1): don't call scm_init_ramap or 
	scm_init_unif unless HAVE_ARRAYS is defined.

	* __scm.h: don't define ARRAYS.

	* Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
	moved here from	libguile_la_SOURCES.
	
1999-11-18  Gary Houston  <ghouston@freewire.co.uk>

	* socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
	functions for network data conversion.

	* numbers.c (scm_num2long, scm_num2longlong):
	throw out-of-range instead of wrong-type-arg if appropriate.
	(scm_iint2str): handle -2^31 correctly.
	(scm_num2long): handle -2^31 bignum correctly.
	(scm_num2long_long): rewrite the bigdig case: basically copied 
	from scm_num2long.
	numbers.h: (SCM_BITSPERLONGLONG): deleted.

	* unif.c (rapr1): use sprintf instead of intprint for unsigned
	longs: intprint can't cope with large values.

	* numbers.c (scm_num2ulong): check more consistently that the
	input is not negative.  if it is, throw out-of-range instead of 
	wrong-type-arg.

	* ramap.c (scm_array_fill_int): don't limit fill to INUM for 
	uvect, ivect or llvect.
	Check that fill doesn't overflow short uniform array.

	* __scm.h: add another long to the definition of long_long and
	ulong_long.

	* unif.c (scm_raprin1): use 'l' instead of "long_long" in the
	print representation of llvect.  read can't handle more than
	one character.
	(scm_dimensions_to_uniform_array): make "fill" an optional argument
	instead of a rest argument.

	* tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
	tag 29 for now.

	* __scm.h: don't mention LONGLONGS.

	* unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
	replace LONGLONGS with HAVE_LONG_LONGS as set by configure.

1999-11-17  Gary Houston  <ghouston@freewire.co.uk>

	* net_db.c (scm_inet_aton): throw errors using the misc-error key
	instead of system-error.  inet_aton doesn't set errno.
	system-error isn't right in gethost either, since it's throwing
	the value of h_errno instead of errno. so:
	(scm_host_not_found_key, scm_try_again_key,
	scm_no_recovery_key, scm_no_data_key): new error keys.
	(scm_resolv_error): new procedure, use the new keys.
	(scm_gethost): call scm_resolv_error not scm_syserror_msg.

1999-11-16  Gary Houston  <ghouston@freewire.co.uk>

	* error.c: (various): use scm_cons instead of scm_listify
	to build short lists.

1999-11-03  Gary Houston  <ghouston@freewire.co.uk>

	* socket.c (scm_fill_sockaddr): zero the address structure before
	use, in case it has a sin_len field and the OS doesn't like random
	values (thanks to Bertrand Petit).

1999-10-26  Mark Galassi  <rosalia@lanl.gov>

	* gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
	a const char * argument, upon suggestion from Lynn Winebarger.

1999-10-26  Gary Houston  <ghouston@freewire.co.uk>

	* strports.c (st_end_input): avoid dubious pointer arithmetic.

1999-10-24  Gary Houston  <ghouston@freewire.co.uk>

	* Move the responsibility for resetting port buffers from the
	caller of the ptob seek procedure to the implementation.  This
	gives more control in general to the ptob seek: in particular the
	change of 1999-10-20 can be made to work without breaking seek on
	string ports.  There's a comment in NEWS about upgrading port
	types.
	
	* ports.c (scm_seek): don't reset the port buffers here.

	* fports.c (fport_seek): reset the buffers, except for the
	0 SEEK_CUR case.

	* strports.c (st_end_input): (bug fix): decrement pt->read_pos by
	offset.  check that it's not less than read_buf.
	(st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
	case and currently reading.

1999-10-20  Gary Houston  <ghouston@freewire.co.uk>

	* ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
	so that unread chars are not needlessly discarded.  (thanks to
	Roland Orre).

1999-10-18  Gary Houston  <ghouston@freewire.co.uk>

	* fports.c (scm_fdes_to_port): always set rw_random if the fdes is
	random access.  rw_active needs to be maintained even for single
	directional ports, otherwise scm_seek and probably other things are
	broken.  (thanks to Roland Orre).

	* strports.c (scm_mkstrport): set rw_random to 1 unconditionally.

	* ports.c (scm_add_to_port_table): initialise rw_random to 0.

	* ports.h (scm_port): change the comments on rw_random and rw_active.

1999-10-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* ioext.c: Added #include "feature.h".

	These changes turns `delay' into a memoizing macro.  This is
	because it may be expanded before evaluation if it occurs at the
	beginning of a body.  (Thanks to Lauri Alanko.)
	
	* eval.c, eval.h (scm_sym_delay): New global symbol.

	* tags.h (SCM_IM_DELAY): New immediate symbol.

	* print.c (scm_isymnames): Printed representation.

	* eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
	(scm_m_delay): Turned into a memoizing macro.

	* Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.

1999-10-11  Jim Blandy  <jimb@savonarola.red-bean.com>

	* gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
	protected from GC while building the vector.  (Thanks to Bernard
	Urban and Greg Harvey.)

1999-10-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* throw.c (handler_message): Display backtrace if backtraces
	enabled.

1999-10-05  Jim Blandy  <jimb@savonarola.red-bean.com>

	the autogen.sh script to create generated files like these.

	* numbers.c (scm_string_to_number): Signal an error if radix is
	less than two.  (Thanks to Jorgen Schaefer.)

	* print.c (scm_write, scm_display, scm_newline, scm_write_char):
	Don't assume that the current output port is valid.  Somebody
	might close it.  (Thanks to Bernard Urban.)

1999-10-02  Jim Blandy  <jimb@zwingli.cygnus.com>

	* scmconfig.h.in: Regenerated.

	* Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.

Mon Sep 27 17:15:14 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* __scm.h: Fix a bunch of macros that were missing do-while(0)
	sandwiches. 

	* debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
	semicolon) exposed by the above change.

1999-09-27  Greg J. Badros  <gjb@cs.washington.edu>

	* stacks.c: Avoid compiler warning re: unitialized var.

	* scmconfig.h.in: Added DEBUG_FREELIST

	* pairs.h: Fix macro that was not do-while(0) sandwiched.

	* gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
 	scm_map_free_list

1999-09-23  Gary Houston  <ghouston@freewire.co.uk>

	* ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
	instead of in scm_init_filesys.

	* init.c (scm_boot_guile_1): don't call scm_init_posix or
	scm_init_filesys unless	HAVE_POSIX is defined.
	don't call scm_init_netdb or scm_init_socket unless
	HAVE_NETWORKING is defined.

	* Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
	net_db.c, socket.c: moved here from libguile_la_SOURCES.

1999-09-25  Jim Blandy  <jimb@savonarola.red-bean.com>

	* root.c (scm_make_root): Initialize all the fields of the new
	root.  GC could happen any time, you know.  (Thanks to Greg
	Harvey.)

	* numbers.c (scm_number_to_string): Signal an error if radix is
	less than two.  (Thanks to Jorgen Schaefer.)

	* Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
	so automake will actually generate rules for it.
	* Makefile.in: Regenerated.

1999-09-21  Jim Blandy  <jimb@savonarola.red-bean.com>

	* backtrace.c: #include "_scm.h" before testing whether
	HAVE_UNISTD_H is #defined.

1999-09-20  Jim Blandy  <jimb@savonarola.red-bean.com>

	* read.c (scm_read): Don't assume that scm_cur_inp is always open.
	* ports.c (scm_read_char): Same.
	* ioext.c (scm_read_line): Same.
	(Thanks to Bernard Urban.)

1999-09-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
	in SCM_ASSERT macro.
	numbers.c: Removed #ifndef SCM_RECKLESS at places where type
	checking may invoke a generic.  (Thanks to Michael Livshin.)

	* __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.

	* numbers.c (scm_max, scm_min, scm_sum, scm_difference,
	scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
	generic function if the asubr is called with only one arg.

1999-09-20  Gary Houston  <ghouston@freewire.co.uk>

	* scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
	HAVE_RESTARTABLE_SYSCALLS.
	(scm_init_scmsigs): use siginterrupt if it's available.  not
	everyone who has restartable syscalls has SA_RESTART it seems.

	(scm_sigaction): use scm_num2long/scm_long2num when converting
	SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM.  use
	scm_integer_p to test the type.

1999-09-18  Gary Houston  <ghouston@freewire.co.uk>

	* _scm.h, scmsigs.c: replace HAVE_RESTARTS with
	HAVE_RESTARTABLE_SYSCALLS.

	* strports.c (scm_strport_to_string): create the string from
	pt->read_buf instead of an expression that evaluates to the
	same thing.

	* gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
	from the port: the port's buffer may not be NUL terminated.

1999-09-16  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* Makefile.am (.c.x): Added missing semicolon after `false'.

1999-09-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* print.c (scm_iprin1): Turn `write' and `display' into
	primitive generics and use their associated generic functions in
	scm_iprin1 for GOOPS objects.

	* backtrace.c: #include <unistd.h> if present.

1999-09-14  Jim Blandy  <jimb@savonarola.red-bean.com>

	* Makefile.am (.c.x): Don't create a subshell just to delete the
	.x file and return false.
	* Makefile.in: Regenerated.

1999-09-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* feature.c (scm_create_hook): New function.  Replaces
	scm_make_named_hook which is now deprecated.
	(scm_make_hook_with_name): New primitive.
	(print_hook): Hooks now print in a fancy way.

1999-09-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
	dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
	feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
	procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
	struct.h: Updated copyright notices.

	* srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
	of SCM_NCONSP.  (Thanks to Greg Badros.)

	* gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
	the self subr.

	* eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.

	* backtrace.c: Keep backtraces within specified width by
	adaptively adjusting fancy printing parameters and cut output if
	necessary.
	(scm_display_application): Check args.

1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>

	Change the name of the objects returned by OPENDIR from
	"directory" to "directory stream".  A predicate named "directory?"
	would be confusing.
	* filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
	At the Scheme level, "directory?" -> "directory-stream?".
	(scm_dir_print): Use the phrase "directory stream" in printed form.
	* filesys.h (scm_directory_stream_p): Prototype renamed
	accordingly.

	* Makefile.am (CLEANFILES): Remove versiondat.h; that should only
	be removed by `make distclean', since it's generated by configure.
	* Makefile.in: Regenerated.
	(Thanks to Robert Bihlmeyer.)

	* strop.c (scm_substring_move_x): Signal an error if start1
	doesn't come before end1.  (Thanks to Karoly Lorentey).

	* numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
	calling SCM_NIMP.  (Thanks to Karoly Lorentey).

	* version.c (scm_libguile_config_stamp): Deleted.  See
	corresponding change to ../ice-9/boot-9.scm.
	* versiondat.h.in: Remove definition for GUILE_STAMP.
	* version.h: Delete prototype.
	* Makefile.in: Regenerated.

1999-09-11  Gary Houston  <ghouston@easynet.co.uk>

	* filesys.c (scm_directory_p): new procedure "directory?"  Returns
	a boolean indicating whether its argument is a directory
	port as returned by opendir (thanks to Dirk Herrmann for the
	suggestion.)

1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* backtrace.c (display_frame_expr): Don't print a newline.
	(display_frame): Print the newline here instead.
	(display_backtrace_body): Don't print "Backtrace:".
	(scm_backtrace): Print "Backtrace:" here instead.

1999-09-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* procs.c (scm_setter): Signal WTA if handed an entity or operator
	lacking a setter.

	* feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
	primitives. (Thanks to Greg Badros);
	(scm_hook_to_list): New primitive; Hooks are now smobs.

1999-09-08  Gary Houston  <ghouston@easynet.co.uk>

	* stime.c (bdtime2c): rewrite the ASSERTs.  Accept a value
	of #f for the 10th vector element to avoid an exception
	seen by Bernard Urban.
	(scm_mktime): unneeded ASSERT removed.

1999-09-07  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* eval.c (scm_map, scm_for_each): Converted to dispatch on generic
	if args don't match.

	* __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.

1999-09-06  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* numbers.c: Converted comparison operations to dispatch on
	generic if args don't match.

	* Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.

1999-09-06  James Blandy  <jimb@mule.m17n.org>

	* guile-snarf.c: Deleted.  Snarfing should respect CPP
	conditionals, so it needs to actually run CPP.  Bleah.

1999-09-05  James Blandy  <jimb@mule.m17n.org>

	Handle errors properly in guile-snarf.  (Thanks to Han-Wen Nienhuys.)
	* guile-snarf.in: Be sure to exit with an error if CPP does.
	* Makefile.am (.c.x): Delete the .x file and exit with an error
	status if guile-snarf exits with an error status.
	* Makefile.in: Regenerated.

	* snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
	scm_makekey, which doesn't exist any more.  Guess nobody's using
	this.

	* guile-snarf.c: New implementation of guile-snarf, meant to be
	more robust than the shell script.  I think it's complete, but I
	haven't tested it at all, and I haven't changed the build process
	to actually use it.  We should compare its output against that of
	the existing shell script, for all source files.

	* guile-snarf.c (parse_args): Abort if we haven't handled some
	character type.

1999-09-03  James Blandy  <jimb@mule.m17n.org>

	* load.c (scm_search_path): If the filename has any extension at
	all, ignore the entire list of extensions.  Also, don't check whether
	the file is accessible.  If the file exists, accessible or not, we
	should return it.  Inaccessible files should cause an error later.
	(Thanks to Keisuke Nishida for the suggestions.)

1999-09-02  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* gc.c (cleanup, scm_init_storage): Use on_exit if present and
	atexit not available.  (sunos4.1.4 needs it.)

1999-09-01  James Blandy  <jimb@mule.m17n.org>

	I take it all back --- bcopy does handle overlapping source and
	destination areas correctly.  At least on every system I could
	find.  But it is better to use AC_REPLACE_FUNCS than to introduce
	new CPP conditionals.
	* memmove.c: New file, implementing memmove in terms of bcopy.
	* scmconfig.h.in: Regenerated.

	Allocators should use the `void *' type for generic pointers.
	* gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
	argument and return types.
	* gc.h: Corresponding changes to prototypes.
	(Thanks to Forcer.)

1999-08-31  James Blandy  <jimb@mule.m17n.org>

	* numbers.c (scm_init_numbers): Claim to support the `complex'
	feature, as expected by (ice-9 format).  (Thanks to Ceri Storey.)

	* Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
	find (ice-9 boot-9) when Guile was compiled in a separate
	directory from the source.  (Thanks to Rodney Brown.)
	* Makefile.in: Regenerated.

	* procs.c (scm_make_subr_opt): Fix typo.  Remember to multiply
	table lengths by the size of a single element when growing the
	table.  (Thanks to Bill Schottstaedt.)

1999-08-30  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
	SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
	since that cuts down the time for type dispatch by 50%.

1999-08-30  James Blandy  <jimb@mule.m17n.org>

	* gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
	not a correct substitute for memmove, because it doesn't handle
	overlapping source and destination areas on many platforms.
	Overlaps are the primary reason to use memmove in the first place.
	* ports.c (scm_ungetc): Same.
	* strop.c (scm_substring_move_x): Same.

1999-08-30  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* gc.c (scm_init_storage): Skip registration of cleanup on systems
	which lack atexit.  (Is it important that cleanup is made
	properly? Maybe we should replace all `exit' with `scm_exit' and
	call cleanup there?)

	* struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
	scm_struct_free_standard, scm_struct_free_entity): Declared to
	return scm_sizet instead of size_t.

	* gdbint.c, strports.c: #include <unistd.h>.  (SEEK_SET is defined
	there on sunos4.1.4.)

1999-08-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
	Account for the case when second argument is unbound.

	* strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
	(Thanks to Karoly Lorentey.)

	* gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
	isn't present.  (Thanks to Suzuki Toshiya.)

	* ports.c: Use ANSI C prototypes in definitions.  (Thanks to
	Bernard Urban.)

	* filesys.c (scm_stat2scm): Conditionally use S_ISLNK.  (Thanks to
	Bernard Urban.)

	* dynl-dl.c (RTLD_GLOBAL): Define if non-existent.  (Thanks to
	Bernard Urban and Ian Grant.)

	* Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
	again.  (1.3.4 will be binary incompatible with 1.3.2 because of a
	change in the representation of entities and operators.)

1999-08-29  Gary Houston  <ghouston@easynet.co.uk>

	* ports.c (scm_ungetc): bugfix: if putback_buf is NULL 
	don't allocate zero bytes (thanks to Bill Schottstaedt).

1999-08-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* procs.c (scm_setter): Converted to use generic dispatch.

	* eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
	correctly.

	* load.c (scm_search_path): Don't try extensions which already are
	present at the end of the filename.
        (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)

	* stacks.c (scm_sym_apply): Removed.  (Thanks to Ken Raeburn.)

	Cleanup and simplification of generic method dispatch.
	Also, the quadruple representation of entity and operator
	procedures has been replaced with single.
	
	* tags.h (SCM_IM_HASH_DISPATCH): Removed.
	
	* print.c (scm_isymnames): Removed #@hash-dispatch.

	* objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
	from eval.c; Support 0 arity methods.
	(scm_set_object_procedure_x): Removed scm_sym_atdispatch;
	(scm_apply_generic_env): Removed.
	Replaced slots proc0-3 with procedure.
	
	* objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
	SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
	SCM_OPERATOR_PROCEDURE.
	(SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
	SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
	
	* struct.c, struct.h: Replace 4 procedure slots with one.
	(scm_struct_i_procedure): Replaces scm_struct_i_procedure.

	* gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
	4.

	* eval.c (scm_sym_args): Removed.
	(SCM_CEVAL): Simplified entity application.
	Moved dispatch code to objects.c.

	* procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
	
1999-08-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* sort.c (closureless): Use scm_eval_body.

	* eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
	with a symbol as last form was first called normally and then via
	`map' or some other mechanism using primitive apply, an ILOC was
	returned.

1999-08-26  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	This change extends the representation of primitive procedures
	with more data fields, e.g. a place for documentation and true
	procedure properties.
	
	* procs.c, procs.h (scm_subr_entry): New type: Stores data
	associated with subrs.
	(SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
	SCM_SUBR_DOC): New macros.
	(scm_subr_table): New variable.
	(scm_mark_subr_table): New function.
	
	* init.c (scm_boot_guile_1): Call scm_init_subr_table.

	* gc.c (scm_gc_mark): Don't mark subr names here.
	(scm_igc): Call scm_mark_subr_table.


	This change implements a scheme for letting a generic work as a
	shadow for a primitive procedure.  If the primitive procedure
	can't dispatch on its arguments, control is left over to the
	generic.  Normal wrong type arg errors will be generated until the
	user has hung the first method on the primitive.

	* snarf.h (SCM_GPROC, SCM_GPROC1): New macros.

	* procs.c, procs.h (scm_subr_p): New function (used internally).

	* gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.

	* objects.c, objects.h (scm_primitive_generic): New class.

	* objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.

	* print.c (scm_iprin1): Print primitive-generics.

	* __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
	SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
	
	* eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
	SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
	primitives).  NOTE: This means that it is now *required* to use
	SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
	obscured representation that will be removed in the future anyway,
	so backward compatibility is no problem here).

	* numbers.c: Converted most numeric primitives (all but bit
	comparison operations and bit operations) to dispatch on generic
	if args don't match.

	
	Better support for applying generic functions.

	* eval.c, eval.h (scm_eval_body): New function.

	* objects.c (scm_call_generic_0, scm_call_generic_1,
	scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
	functions.
	
	
	Optimization of the generic function dispatch mechanism.
	
	* eval.c (SCM_CEVAL): Apply the cmethod directly after having
	called scm_memoize_method instead of doing a second lookup.

	* objects.h (scm_memoize_method): Now returns the memoized cmethod.


	Bugfix

	* procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
	scm_sysintern so that the binding connected with the subr name
	isn't cleared when we give set = 0.

	
1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	More transparent handling of ports with print states.
	
	* print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
	SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
	instead of a pair of a port and a print state.  We'll need to cons
	once extra in scm_printer_apply but the type system will be
	cleaner, it will mix better with GOOPS, and, it will be even more
	transparent to the user.

	* print.c (scm_get_print_state): New procedure: Given an output
	port, return the print state associated to it in the current print
	chain, if one exists;
	(scm_port_with_print_state): New procedure: Associate a
	print-state with a port.
	(scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
	(scm_printer_apply): Wrap port and pstate as a smob;
	(print_state_printer): Removed.
	
	* objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.

	* eval.c (scm_init_eval): Use scm_make_smob_type instead of
	scm_newsmob.

	* ports.c (scm_output_port_p): Bugfix: Coerce output port before
	testing (otherwise the port-print-state trick won't be transparent
	to the user; one example where this caused problems was in the
	(ice-9 format) module).

1999-08-23  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
	SCM_UNSPECIFIED instead of the set value.

1999-08-20  James Blandy  <jimb@mule.m17n.org>

	* load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.

	* ports.h (enum scm_port_rw_active): New enum, containing
	SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
	zero).  The debugger knows about enums, but doesn't know about
	#defines.
	(typedef scm_port): Declare rw_active member to be an enum
	scm_port_rw_active.
	* fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
	instead of zero.
	* ports.c (scm_add_to_port_table): Same.
	* strports.c (st_flush, st_end_input): Same.

	* ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
	scm_must_realloc, and scm_done_malloc as appropriate.

	evaluating closures.

1999-08-18  Gary Houston  <ghouston@easynet.co.uk>

	* fports.c (fport_write): use memcpy instead of strncpy, in case
	the data contains NUL.

1999-08-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* gh.h (gh_vector_to_list): Bugfix.  (Thanks to Frank Cieslok.)
	
	* backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
	read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
	scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
	scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
	scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
	scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
	scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
	scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
	scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
	scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
	scm_sym_ as prefix for symbols.

	* debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.

	* eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
	scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
	scm_sym_define, scm_sym_letrec, scm_sym_atapply,
	scm_sym_atcall_cc): Made global.
		
1999-08-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c (scm_sym_args): Made global.

	* objects.c (scm_set_object_procedure_x): Disallow setting of
	procedures for pure generic functions.

1999-08-12  Gary Houston  <ghouston@easynet.co.uk>

	* ports.c (scm_seek): one more: was scm_lseek.  Also changed the
	Scheme name from lseek to seek, but lseek was added recently so
	it shouldn't be a big problem.
	* ports.c, gdbint.c, ioext.c: changed callers.

1999-08-11  Gary Houston  <ghouston@easynet.co.uk>

	* fports.c (fport_input_waiting): if select is used, return 1
	instead of whatever FD_ISSET expands to.  maybe it will be useful
	to interpret the value from the input_waiting ptob procedure as a
	lower bound on the number of bytes available.

	* Mikael asked for a few names to be changed...

	* ports.c (scm_make_port_type): take the write procedure as the 
	second argument instead of the flush procedure.
	* ports.h (scm_ptob_descriptor): rename the ptob procedures:
	fflush -> flush,  read_flush -> end_input,  fclose -> close,
	fill_buffer -> fill_input,  ftruncate -> truncate,
	input_waiting_p -> input_waiting.

	* ports.c (end_input_void_port): was read_flush_void_port.
	(scm_set_port_end_input): was scm_set_port_flush_input.
	(scm_set_port_flush): was scm_set_port_write.
	(scm_set_port_input_waiting): was scm_set_port_input_waiting_p
	(scm_end_input): was scm_read_flush.
	(scm_fill_input): was scm_fill_buffer.
	(scm_flush): was scm_fflush.
	* fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
	(fport_end_input): was local_read_flush.
	(fport_flush): was local_fflush.
	(fport_close): was local_fclose.
	(fport_truncate): was local_ftruncate.

	(st_truncate): was st_ftruncate.
	* vports.c: (sf_flush): was sfflush.
	(sf_close): was sfclose.
	(sf_fill_input): was sf_fill_buffer.
	
	* ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
	change callers.

1999-08-06  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol.  Dispatch
	forms now contain the expressions to be dispatched upon instead of
	depending on a surrounding lambda or let; Generic function
	dispatch has been optimized; `apply' on a generic function now
	works a little bit strangely.  It uses a trick so that the type
	dispatch code in SCM_CEVAL can be reused.

	* objects.h, objects.c (scm_apply_generic_env): Added (used by
	apply).
	(scm_operator_p): Added.
	(scm_sym_atdispatch): Added.
	(scm_set_object_procedure_x): Modified to handle the new style
	generic functions.
	(scm_object_procedures): New debugging procedure.

1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c, eval.h (scm_sym_args): Added.

	* objects.h (SCM_CLASSF_PURE_GENERIC): Added.

	* feature.c, feature.h (scm_c_run_hook): Added.

	* eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
	cdrxnoap and loopnoap instead of begin and loop.

1999-08-04  Gary Houston  <ghouston@easynet.co.uk>

	* ports.c (scm_putc, scm_puts),
	* unif.c (scm_uniform_array_write): use scm_lfwrite.
	* ports.c (scm_putc): change type of first argument from int to	char.
	
1999-08-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

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

	* objects.h (SCM_CLASSF_GOOPS_VALID): Added.
	(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.h (scm_ptob_descriptor): include a write procedure again.
	it's more efficient for unbuffered fports (e.g., sockets.)

	* 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.
	* ports.c (write_void_port): new procedure.
	* vports.c (sf_write): new procedure.
	* ports.c (scm_lfwrite): use ptob->write.
	* strports.c (st_write): new procedure.
	* fports.c (fport_write): new procedure.
	(scm_make_fptob): set write in ptob to fport_write.
	* ports.h: prototype for scm_set_port_write.
	* ports.c (scm_make_port_type): initialise ptob write procedure.
	(scm_set_port_write): new proc.

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>

	* eval.c (scm_m_expand_body): Use scm_cons_source.

	* struct.c (scm_print_struct): Use vtable name.

	* print.c (scm_init_print): Set name of print state type.

	* stacks.c (scm_init_stacks): Set name of stack type.

1999-07-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* eval.c (SCM_CEVAL): Removed old implementation of internal
	define.

	* gsubr.c, procprop.h (scm_i_inner_name): Removed.

	* debug.c, debug.h (scm_reverse_lookup): Added.
	(scm_procedure_name): Use scm_reverse_lookup to lookup the name of
	internal procedure definitions; Don't use scm_i_inner_name.

	* eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
	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
	procedure source before calling scm_unmemocopy instead of faking
	an environment.

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.)
