2002-10-04  Marius Vollmer  <mvo@zagadka.ping.de>

	* scmsigs.h (scm_sigaction_for_thread): New prototype.
	* scmsigs.c (got_signal): Removed.
	(signal_handler_cells, signal_handler_threads): New.
	(take_signal): Queue the cell of the signal for the specified
	thread.  Reset the signal handler on systems that don't have
	sigaction.
	(sys_deliver_signals): Removed.
	(close_1): New.
	(scm_sigaction_for_thread): Renamed from scm_sigaction and
	extended to also set the thread of a signal and allocate a cell
	for it.  Keep the Scheme name "sigaction".  Check that signum is
	within range.  Also, use SCM_VECTOR_REF instead of SCM_VELTS.
	(scm_sigaction): Implement in terms of scm_sigaction_for_thread.
	(scm_init_scmsigs): Allocate signal_handler_cells and
	signal_handler_threads vectors.

	* async.c: Removed GUILE_OLD_ASYNC_CLICK code.  Reorganized so
	that system asnycs and user asyncs are separated.  Reimplemented
	system asyncs to work per-thread.

	* gc.c (scm_init_gc): Do not use scm_system_async.

	* async.h (scm_asyncs_pending, scm_set_tick_rate,
	scm_set_switch_rate, scm_system_async_mark_from_signal_handler):
	Removed prototypes.
	(scm_i_queue_async_cell): New.
	
	* __scm.h (scm_asyncs_pending_p): Removed.
	(SCM_ASYNC_CLICK): Check scm_active_asyncs instead of
	scm_asyncs_pending_p.

	* async.h (scm_system_async_mark_for_thread): New prototype.

	* __scm.h: Removed GUILE_OLD_ASYNC_CLICK code.

	* root.h (scm_root_state): Added new "active_asyncs" slot.
	* root.c (scm_make_root): Initialize it to SCM_EOL.

	* coop-defs.h (coop_t): Added new "handle" slot.
	* coop-threads.c (all_threads, scm_current_thread,
	scm_all_threads, scm_i_thread_root): New.
	(scm_threads_init): Add main thread to all_threads.
	(scheme_launch_thread): Remove thread from all_threads when it
	terminates.
	(scm_call_with_new_thread): Initialize handle slot of coop_t
	structure and add new thread to all_threads.
	(scm_spawn_thread): Likewise.

	* threads.h (scm_current_thread, scm_all_threads): New prototypes.
	* threads.c (scm_current_thread, scm_all_threads): Register as
	primitives.

	* dynl.c: Use scm_lt_ prefix for libltdl functions.

	* script.c (scm_compile_shell_switches): Fix bad spelling of
	`explicitly' in comment.

2002-09-28  Neil Jerram  <neil@ossau.uklinux.net>

	* posix.c (scm_geteuid, scm_getegid, scm_seteuid, scm_setegid):
	Refer to provided? in doc string rather than deprecated feature?.

2002-09-24  Gary Houston  <ghouston@arglist.com>

	* inline.h (scm_double_cell): prevent reordering of statements
	with any following code (for GCC 3 strict-aliasing).
	* numbers.c (scm_make_real), num2float.i.c (FLOAT2NUM): removed
	the earlier version of the reordering prevention.

2002-09-19  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* inline.h (scm_double_cell): move SET_GCMARK set out of if body.

	* gc-malloc.c (scm_gc_register_collectable_memory): more overflow
	protection.

2002-09-08  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* inline.h: include stdio.h

	* smob.c (free_print): abort if scm_debug_cell_accesses_p is set

2002-09-05  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* gc-segment.c (scm_i_make_initial_segment): check user settings
	for sanity.

	* gc-malloc.c (scm_gc_init_malloc): check user settings for

	* struct.h: change scm_structs_to_free to scm_i_structs_to_free

	* gc-malloc.c (scm_gc_register_collectable_memory): use floats;
	these won't ever wrap around with high memory usage. Thanks to
	Sven Hartrumpf for finding this.

	* gc-freelist.c: include <stdio.h>

	* gc-malloc.c: add DEBUGINFO for mtrigger GCs.

2002-09-01  Marius Vollmer  <mvo@zagadka.ping.de>

	* snarf.h (SCM_DEFINE_PUBLIC): New.

2002-08-30  Marius Vollmer  <mvo@zagadka.ping.de>

	* socket.c (scm_addr_vector): Added size of address to arguments.
	Use it to avoid accessing a non-existent path in a sockaddr_un.
	Changed all callers.

2002-08-29  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* gc.h: remove DOUBLECELL card flags.

	* gc-malloc.c (scm_calloc): try to use calloc() before calling
	scm_realloc().

	* gc-segment.c (scm_i_initialize_heap_segment_data): remove card
	init loop; handle this from scm_init_card_freelist()

	* gc-card.c (scm_init_card_freelist): init bit vector here.

	* numbers.c (scm_make_real): prevent reordering of statements
	num2float.i.c (FLOAT2NUM): idem
