2005-08-12  Marius Vollmer  <mvo@zagadka.de>

	* numbers.c: Use scm_from_bool instead of SCM_BOOL.  Thanks to
	Peter Gavin!

2005-08-06  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_any, scm_string_every, scm_string_tabulate,
	scm_string_trim, scm_string_trim_right, scm_string_trim_both,
	scm_string_index, scm_string_index_right, scm_string_skip,
	scm_string_skip_right, scm_string_count, scm_string_map,
	scm_string_map_x, scm_string_for_each, scm_string_for_each_index,
	scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for
	procedures called in loops.

2005-08-02  Kevin Ryde  <user42@zip.com.au>

	* strports.c (st_flush): Increase buffer by 1.5x when growing, to
	avoid lots of copying where previoulsy growing by only 80 bytes at a
	time.

2005-08-01  Marius Vollmer  <mvo@zagadka.de>

	* modules.h, modules.c (scm_eval_closure_module): Removed, we
	already have scm_lookup_closure_module, which does the same thing.
	
2005-08-01  Marius Vollmer  <mvo@zagadka.de>

	New marking algorithm for weak hashtables that fixes the problem
	that references from the non-weak value to the associated weak
	key (for example) would prevent the entry from ever being dropped.

	Guardians have been changed back to their original semantics and
	are no longer greedy and no longer drop cycles.
	
	* gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
	hashtable and guardian machinery but call the relevant functions
	directly.

	* guardians.h, guardians.c, deprecated.h,
	deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
	scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
	Deprecated and moved into deprecated.[ch].

	* guardians.h, guardians.c: Mostly rewritten.
	(scm_i_init_guardians_for_gc,
	scm_i_identify_inaccessible_guardeds,
	scm_i_mark_inaccessible_guardeds): New.
	(scm_make_guardian): Removed greedy_p argument.
	
	* weaks.h, weaks.c (SCM_I_WVECT_TYPE, SCM_I_SET_WVECT_TYPE): New.
	(SCM_I_WVECT_N_ITEMS, SCM_I_SET_WVECT_N_ITEMS): New.
	(SCM_WVECTF_NOSCAN, SCM_WVECT_NOSCAN_P): Removed.
	(scm_weaks_prehistory): Removed.
	(scm_i_init_weak_vectors_for_gc, scm_i_mark_weak_vector,
	scm_i_mark_weak_vectors_non_weaks,
	scm_i_remove_weaks_from_weak_vectors, scm_i_remove_weaks): New.
	(scm_weak_vector_gc_init, scm_mark_weak_vector_spines,
	scm_scan_weak_vectors): Removed.
	
	* hashtab.h (scm_i_scan_weak_hashtables): New.
	* hashtab.c (make_hash_table, scm_i_rehash): Do not use
	SCM_WVECTF_NOSCAN.
	(hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of
	t->n_items.
	(scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
	to latter.  Do not scan the alists themselves, this is done by the
	weak vector code now.  Just update the element count.

	* vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
	to latter.  The type is now only part of the cell word.
	(SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise.

	* init.c (scm_i_init_guile): Do not call scm_weaks_prehistory.

2005-07-18  Mikael Djurfeldt  <mdj@d14n36.pdc.kth.se>

	Some changes towards making it possible to run Guile on the EM64T
	platform.

	* gc.c (scm_gc_stats): Bugfix: Measure size of the type we are
	mallocating for (unsigned long *bounds).

	* hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to
	scm_t_bits before storing them in the type word.
	
	* gc.c (tag_table_to_type_alist): Modified type of c_tag from
	scm_t_bits to int.

2005-07-12  Kevin Ryde  <user42@zip.com.au>

	* eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and
	SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy.
	* pairs.c (scm_error_pair_access): Use scm_from_locale_string rather
	than scm_makfrom0str.
	Reported by Ken Raeburn.
	
	* gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to
	scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when
	returning SCM_GC_CARD_BVEC.
	
	* pairs.c (scm_error_pair_access): Plain ascii ' in error message
	rather than latin-1 acute accent, the latter may not print on all
	terminals.

	* srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and
	trailing deletions, so as to return a substring if those are the only
	changes.

2005-07-10  Kevin Ryde  <user42@zip.com.au>

	* socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
	for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
	(scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
	scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.

2005-07-01  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* gc-card.c (scm_i_card_statistics): init tag.

	* gc.c (tag_table_to_type_alist): check type of tag. Should be integer.

2005-06-18  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* fports.c (s_scm_open_file): add the b flag for binary to the doc
	string.

2005-06-25  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
	last change, use plain copy-on-write substrings, the individual
	descriptions in the srfi don't mention shared storage (only the
	introduction does).

	* strings.c (scm_take_locale_stringn): Use realloc to make room for
	null-terminator, rather than mallocing a whole new block.
	(scm_take_locale_string): Use scm_take_locale_stringn len==-1.

2005-06-12  Marius Vollmer  <mvo@zagadka.de>

	* ramap.c (scm_array_index_map_x): First test for real arrays,
	then check for generalized vectors.  This ensures that the
	generalized vector case need only work with zero-origin ranges.
	(scm_ra_eqp, scm_ra_compare): Use the new array handle functions
	to access the target array, making these functions work with all
	kinds of arrays, not just bit arrays.

	* gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
	gh_list.c, gh_predicates.c: Deprecated everything.

	* environments.c (environment_default_folder,
	environment_default_observer): Do not use gh_call3, gh_call1.

2005-06-10  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* modules.c (s_scm_eval_closure_module): new function. Return the
	module inside an eval-closure.

	* gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
	table. This means that procedure properties are GC'd if the
	procedure dies.

2005-06-11  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_filter, scm_string_delete): For char and
	charset cases, count chars kept and build a string in a second pass,
	rather than using a cons cell for every char kept.  Use a shared
	substring when nothing removed (such sharing is allowed by the srfi).

2005-06-09  Han-Wen Nienhuys  <hanwen@xs4all.nl>

	* gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
	string, so live object stats can be sorted with string<?. 

2005-06-06  Marius Vollmer  <mvo@zagadka.de>

	* print.c (iprin1): When writing a string, collect all characters
	that can be printed directly into one call to scm_lfwrite.
	Previously, every character was output with its own call to
	write(2) on unbuffered ports.

	* eval.c (scm_eval_options_interface): Use
	scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
	and SCM_CRITICAL_SECTION_END.

	* unif.c (scm_array_in_bounds_p): First test for real arrays, then
	check for generalized vectors.  This ensures that the generalized
	vector case need only work with zero-origin ranges.

2005-06-06  Kevin Ryde  <user42@zip.com.au>

	* srfi-13.c (scm_string_split): Compare char/char in scan.  Mixing an
	unsigned int SCM_CHAR and a char string meant an 8-bit char was never
	matched.

2005-06-05  Marius Vollmer  <mvo@zagadka.de>

	* eval.c: Added comment on how to make case 1.1 of
	r5rs_pitfall.test succeed.

	From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!

 	* hashtab.h: Bugfix: use SCM_API (WAS: extern).
 
 	* socket.c: Remove obsolete comment about socklen_t.
 	(s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code.
 
 	* numbers.h (isnan)[__MINGW32__]: Remove.
 
 	* Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add
 	DEFAULT_INCLUDES when cross compiling.
 
 	* threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines.

 	* stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use
	SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS.  (Changed slightly
	from Jan's patch.)
 
2005-05-22  Marius Vollmer  <mvo@zagadka.de>

	* unif.c (scm_make_shared_array): Add old base to new base since
	scm_array_handle_pos does not include the base.
	(scm_aind): Likewise.

	* ports.c (scm_putc, scm_puts): Assert that the port argument is a
	output port.

2005-05-12  Neil Jerram  <neil@ossau.uklinux.net>

	Mac OS X compile warning fixes, reported by Richard Todd.
	
	* unif.c (scm_i_read_array): Declare rank as ssize_t, to guarantee
	that it is signed.

	* strports.c (st_resize_port): Add unsigned char cast.
	(scm_mkstrport): Make read/write_buf cast unsigned.

	* srfi-13.c (string_titlecase_x): Add unsigned char cast.

	* rdelim.c (scm_read_line): Initialize slen.

	* load.c (scm_search_path): Remove weird >=1, and add
	parentheses to clarify conditions.

	* hash.c (scm_hasher): Add const unsigned char cast.

	* gh_data.c (gh_chars2byvect): Add scm_t_int8 cast.
