2005-03-09  Marius Vollmer  <mvo@zagadka.de>

	* script.c (scm_compile_shell_switches): Added 2005 to Copyright
	years.

2005-03-09  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc-card.c (scm_i_sweep_card): Do not increase/decrease
	scm_gc_running_p.  Sweeping can happen in parallel with
	allocation.

	* inline.h: Updated comments for current threading implementation.

	* threads.h, threads.c (scm_i_frame_single_threaded): Removed.
	(scm_i_thread): Removed unused signal_asyncs field.
	(threads_mark): Do not mark it.
	(guilify_self_1): Do not initialize it.  Do initialize
	continuation_root field.
	(do_thread_exit): Do not remove thread from all_threads list.
	(on_thread_exit): Do it here, after leaving guile mode.
	(sleep_level): Removed.
	(scm_i_thread_put_to_sleep): Leave thread_admin_mutex locked when
	returning.  Do not support recursive sleeps.
	(scm_i_thread_wake_up): Expect thread_admin_mutex to be locked on
	entry.  Do not support recursive sleeps.

	* fluids.c (ensure_state_size, ensure_all_state_sizes,
	resize_all_states): Collapsed ensure_state_size and
	ensure_all_state_sizes into one function named resize_all_states.
	Allocate new vectors outside of single threaded region.  Do only
	simple things inside that region.
	 (scm_make_fluid, scm_make_dynamic_state): Lock fluid_admin_mutex
	while adding to the global lists.
	

2005-03-08  Marius Vollmer  <mvo@zagadka.de>

	libltdl is no longer distributed.  We expect it to be installed
	already.
	
	* Makefile.am (INCLUDES): Removed @LTDLINCL@.

	* threads.h, async.h, threads.c (SCM_CRITICAL_SECTION_START,
	SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
	they also block/unblock execution of asyncs and call
	scm_async_click which is declared in async.h but threads.h can not
	include async.h since async.h already includes threads.h.
	(scm_i_critical_section_level): New, for checking mistakes in the
	use of the SCM_CRITICAL_SECTION_* macros.
	(scm_i_critical_section_mutex): Make it a recursive mutex so that
	critical sections can be nested.

	not zero.
	
	* threads.h, threads.c (scm_frame_lock_mutex): New.
	(scm_frame_critical_section): Take mutex as argument.
	(framed_critical_section_mutex): New, used as default for above.
	(scm_init_threads): Initialize it.
	(scm_threads_prehistory): Do not initialize thread_admin_mutex and
	scm_i_critical_section_mutex; both are initialized statically.
	
	* continuation.c, deprecated.c, goops.c, guardians.c keywords.c,
	libguile_la-arrays.loT, objprop.c, ports.c, smob.c, sort.s,
	srcprop.c, stime.c, struct.c, throw.c, regex-posix.c: Include
	"libguile/async.h" for SCM_CRITICAL_SECTION_START/END.

	* debug.c (scm_debug_options): Replace
	SCM_CRITICAL_SECTION_START/END with a frame and
	scm_frame_critical_section.

	* continuations.c (scm_make_continuation): No longer a critical
	section.

	* threads.c (scm_try_mutex): Renamed argument for consistency.

	* root.c (scm_call_with_dynamic_root): New docstring.

	* eval.c: Define _GNU_SOURCE.

2005-03-02  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	Big merge from the mvo-thread-cleanup branch. The main changes
	are:
	
	- The dynamic roots functionality has been split into dynamic
	  states and continuations barriers.  Fluids have been
	  reimplemented and can now be garbage collected.
	
	- Initialization of Guile now works in a multi-thread friendly
	  manner.  Threads can freely enter and leave guile mode.

	- Blocking on mutexes or condition variables or while selecting
	  can now be reliably interrupted via system asyncs.

	- The low-level threading interface has been removed.

	- Signals are delivered via a pipe to a dedicated 'signal delivery
	  thread'.
	
	- SCM_DEFER_INTS, SCM_ALLOW_INTS etc have been deprecated.

	* throw.c (scm_handle_by_message): Exit only the current thread,
	not the whole process.
	(scm_handle_by_message_noexit): Exit when catching 'quit.

2005-02-27  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	block.

2005-02-25  Marius Vollmer  <mvo@zagadka.de>

	so that no two weak alist vectors share a spine.
	(scm_hash_fn_create_handle_x): Deal with a possible rehashing
	during GC before inserting the new alist cell.

2005-02-23  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* unif.c (prototype_to_type): Bugfix: Don't compare prototype to
	the prototypical examples mentioned in the old reference manual.
	Instead keep the old semantics of dispatching on type.  (Yes, this

	interface is not to break old code.)

2005-02-08  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* deprecated.h (SCM_ARRAY_DIMS): Rename scm_i_attay_dims -->
	scm_i_array_dims.

	* numbers.c (scm_ash): Rewrite using shifts, much faster than
	integer-expt and multiply/divide.  Inexacts and fractions no longer
	supported (they happened to work before for left shifts, but not
	right).  Don't really need inexacts and fractions, since ash is
	documented as a "bitwise operation", and all the rest of those only
	take exact integers.

2005-01-24  Kevin Ryde  <user42@zip.com.au>

	* posix.c (scm_setlocale): Force errno=EINVAL for an error, since
	POSIX and C99 don't document errno being set.  Reported by Bruno
	Haible.
	(scm_flock): Update docstring from manual.

	* random.c (scm_i_init_rstate): Compare w to -1 not 0xffffffffUL, now
	that it's an scm_t_int32.  Otherwise gcc 3.4 says it's always false on
	a 64-bit system.

	* scmsigs.c (scm_sigaction_for_thread): Use scm_to_long for
	sa_handler, needs to be a long on 64-bit systems where int is only 32

	scm_class_unknown, scm_port_class, scm_smob_class,
	scm_no_applicable_method, scm_class_of): Moved from objects to
	goops since they are only useable once goops has been loaded.
	(scm_classes_initialized): Removed.
	(scm_class_of): Do not check it.
	(create_standard_classes): Do not set it.
	
2005-01-17  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	its value.

	Enclosed arrays are now their own smob.  This has been done to
	make the code more explicit about them and to prepare for the time
	when generalized vectors include arbitrary one-dimensional

	use of an array as their storage 'vector'.  When all generalized
	vectors are allowed as storage, including one-dimensional arrays,

2004-11-10  Marius Vollmer  <mvo@zagadka.de>

	* ramap.c (cind): Changed second arg to be pointer to long instead
	of uniform vector.
	(scm_ramapc): Allocate index vector with scm_malloc and not as
	uniform vector.  Wrap it in a frame so that it gets properly freed.
	(scm_array_index_map_x): Likewise.

	* unif.c: Changed all uses of scm_array_prototype to
	scm_array_creator. (scm_i_get_old_prototype): Signal error when no
	prototype is known.
	(scm_uniform_array_read_x, scm_uniform_array_write): Reimplemented
	in terms of scm_uniform_vector_read_x and
	scm_uniform_vector_write, respectively.  Strings and
	bitvector support has been dropped.
	
	* srfi-4.h, srfi-4.c: Do not include <libguile.h>, include the
	needed files directly.  Include config.h, <unistd.h> and <io.h>
	when available.
	(scm_uniform_vector_read_x, scm_uniform_vector_write): New.

2004-11-09  Marius Vollmer  <mvo@zagadka.de>

	* gh_data.c (gh_uniform_vector_length): Properly use
	scm_c_uniform_vector_length instead of scm_uniform_vector_length.

	(make_uvec): ...but not here.
	(coerce_to_uvec): Use new generalized vector functions to handle
	all kinds of vectors in one go.
	
	* tags.h (scm_tc7_bvect): Renamed to scm_tc7_unused7, renaming the
	remaining scm_tc7_unused tags to get a neatly ordered list.

	(scm_bit_count, scm_bit_position, scm_bit_set_star_x,
	scm_bit_count_star, scm_bit_invert_x, scm_istr2bve): Rewritten
	using the new C API for bitvectors and maybe count_ones or
	find_first_one, as appropriate.
	(SCM_I_MAX_LENGTH, SCM_BITVECTOR_P, SCM_BITVECTOR_BASE,
	SCM_SET_BITVECTOR_BASE, SCM_BITVECTOR_MAX_LENGTH,
	SCM_BITVECTOR_LENGTH, SCM_MAKE_BITVECTOR_TAG,

	(scm_raprin1): Only print enclosed arrays.

	* Makefile.am (DOT_DOC_FILES): Added srfi-4.doc.

2004-11-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* srfi-4.c (make_uvec): Use SCM_I_SIZE_MAX instead of SIZE_MAX for
	added portability.

	* chars.c (scm_charnames, scm_charnums): Added "sp" as an alias
	for "space".  Thanks to Bruce Korb!

	* rw.c (scm_read_string_x_partial): Bugfix, apply offset to dest
	only after dest has been set.  Thanks to Hyper Division!

	* gh_data.c (gh_uniform_vector_length): Use
	scm_uniform_vector_length instead of SCM_UVECTOR_LENGTH.

2004-11-03  Marius Vollmer  <mvo@zagadka.de>
