Fri Jul 31 14:00:29 1998  Ross Johnson  <[e-mail]>

	* cleanup.c (_pthread_destructor_push): Implement. This is just a
	call to _pthread_handler_push().
	(_pthread_destructor_pop_all): Implement. This is significantly
	different to _pthread_handler_pop_all().

	* Makefile (SRCS): Create. Preliminary.

	* windows.h: Create. Contains Win32 definitions for compile
	testing. This is just a standin for the real one.

	(_pthread_new_thread): Alter "if" flow to be more natural.

	* cleanup.c (_pthread_handler_push): Same as below.

	* create.c (pthread_create): Same as below.

	* private.c (_pthread_new_thread): Rename "new" to "new_thread".
	Since when has a C programmer been required to know C++?

Tue Jul 28 14:04:29 1998  Ross Johnson  <[e-mail]>

	* implement.h: Add _PTHREAD_VALID macro.

	* sync.c (pthread_join): Modify to use the new thread
	type and _pthread_delete_thread(). Rename "target" to "thread".
	Remove extra local variable "target".
	(pthread_detach): Ditto.

	* signal.c (pthread_sigmask): Move init of "us" out of inner block.
	Fix instance of "this" should have been "us". Rename "us" to "thread".

	* sched.c (pthread_setschedparam): Modify to use the new thread
	type.
	(pthread_getschedparam): Ditto.

	* private.c (_pthread_find_thread): Fix return type and arg.

	* implement.h: Remove _PTHREAD_YES and _PTHREAD_NO.
	(_pthread_new_thread): Add prototype.
	(_pthread_find_thread): Ditto.
	(_pthread_delete_thread): Ditto.
	(_pthread_new_thread_entry): Remove prototype.
	(_pthread_find_thread_entry): Ditto.
	(_pthread_delete_thread_entry): Ditto.
	(  _PTHREAD_NEW, _PTHREAD_INUSE, _PTHREAD_EXITED, _PTHREAD_REUSE):
	Add.


	* create.c (pthread_create): Minor rename "us" to "new" (I need
	these cues but it doesn't stop me coming out with some major bugs
	at times).
	Load start_routine and arg into the thread so the wrapper can
	call it.

	* exit.c (pthread_exit): Fix pthread_this should be pthread_self.

	* cancel.c (pthread_setcancelstate): Change
 	_pthread_threads_thread_t * to pthread_t and init with
 	pthread_this().
	(pthread_setcanceltype): Ditto.

Mon Jul 27 17:46:37 1998  Ross Johnson  <[e-mail]>

	* create.c (pthread_create): Start of rewrite. Not completed yet.

	* private.c (_pthread_new_thread_entry): Start of rewrite. Not
	complete.

	* implement.h (_pthread_threads_thread): Rename, remove thread
	member, add win32handle and ptstatus members.
	(_pthread_t): Add.

	* pthread.h: pthread_t is no longer mapped directly to a Win32
	HANDLE type. This is so we can let the Win32 thread terminate and
	reuse the HANDLE while pthreads holds it's own thread ID until
	the last waiting join exits.

Mon Jul 27 00:20:37 1998  Ross Johnson  <[e-mail]>

	* private.c (_pthread_delete_thread_entry): Destroy the thread
 	entry attribute object before deleting the thread entry itself.

	* attr.c (pthread_attr_init): Initialise cancel_pending = FALSE.
	(pthread_attr_setdetachstate): Rename "detached" to "detachedstate".
	(pthread_attr_getdetachstate): Ditto.

	* exit.c (_pthread_exit): Fix incorrect check for detachedstate.

Sun Jul 26 13:06:12 1998  Ross Johnson  <[e-mail]>

	* implement.h (_pthread_new_thread_entry): Fix prototype.
	(_pthread_find_thread_entry): Ditto.
	(_pthread_delete_thread_entry): Ditto.
	(_pthread_exit): Add prototype.

	* exit.c (_pthread_exit): New function. Called from pthread_exit()
	and _pthread_start_call() to exit the thread. It allows an extra
	argument which is the return code passed to _endthreadex().
	(_pthread_exit): Move thread entry delete call from _pthread_vacuum()
	into here. Add more explanation of thread entry deletion.
	(_pthread_exit): Clarify comment.

	* create.c (_pthread_start_call): Change pthread_exit() call to
	_pthread_exit() call.

	* exit.c (_pthread_vacuum): Add thread entry deletion code
	moved from _pthread_start_call(). See next item.
	(pthread_exit): Remove longjmp(). Add mutex lock around thread table
	manipulation code. This routine now calls _enthreadex().

	* create.c (_pthread_start_call): Remove setjmp() call and move
	cleanup code out. Call pthread_exit(NULL) to terminate the thread.

1998-07-26  Ben Elliston  <[e-mail]>

	* tsd.c (pthread_getspecific): Update comments.

	* mutex.c (pthread_mutexattr_setpshared): Not supported; remove.
	(pthread_mutexattr_getpshared): Likewise.

	* pthread.h (pthread_mutexattr_setpshared): Remove prototype.
	(pthread_mutexattr_getpshared): Likewise.

Sun Jul 26 00:09:59 1998  Ross Johnson  <[e-mail]>

	* sync.c: Rename all instances of _pthread_count_mutex to
	_pthread_table_mutex.

	* implement.h: Rename _pthread_count_mutex to
	_pthread_table_mutex.

	* global.c: Rename _pthread_count_mutex to
	_pthread_table_mutex.

	* create.c (pthread_create): Add critical sections.
	(_pthread_start_call): Rename _pthread_count_mutex to
	_pthread_table_mutex.

	* cancel.c (pthread_setcancelstate): Fix indirection bug and rename
	"this" to "us".

	* signal.c (pthread_sigmask): Rename "this" to "us" and fix some
	minor syntax errors. Declare "us" and initialise it.

	* sync.c (pthread_detach): Rename "this" to "target".

	* pthread.h: Converting PTHREAD_* defines to alias the (const int)
	values in global.c.

	* global.c: Started converting PTHREAD_* defines to (const int) as
 	a part of making the eventual pthreads DLL binary compatible
 	through version changes.

	* condvar.c (cond_wait): Add cancelation point. This applies the
	point to both pthread_cond_wait() and pthread_cond_timedwait().

	* exit.c (pthread_exit): Rename "this" to "us".

	* implement.h: Add comment.

	* sync.c (pthread_join): I've satisfied myself that pthread_detach()
	does set the detached attribute in the thread entry attributes
	to PTHREAD_CREATE_DETACHED. "if" conditions were changed to test
	that attribute instead of a separate flag.

	* create.c (pthread_create): Rename "this" to "us".
	(pthread_create): cancelstate and canceltype are not attributes
	so the copy to thread entry attribute storage was removed.
	Only the thread itself can change it's cancelstate or canceltype,
	ie. the thread must exist already.

	* private.c (_pthread_delete_thread_entry): Mutex locks removed.
	Mutexes must be applied at the caller level.
	(_pthread_new_thread_entry): Ditto.
	(_pthread_new_thread_entry): Init cancelstate, canceltype, and
	cancel_pending to default values.
	(_pthread_new_thread_entry): Rename "this" to "new".
	(_pthread_find_thread_entry): Rename "this" to "entry".
	(_pthread_delete_thread_entry): Rename "thread_entry" to "entry".

	* create.c (_pthread_start_call): Mutexes changed to
	_pthread_count_mutex. All access to the threads table entries is
	under the one mutex. Otherwise chaos reigns.

Sat Jul 25 23:16:51 1998  Ross Johnson  <[e-mail]>

	* implement.h (_pthread_threads_thread): Move cancelstate and
 	canceltype members out of pthread_attr_t into here.

	* fork.c (fork): Add comment.

1998-07-25  Ben Elliston  <[e-mail]>

	* fork.c (fork): Autoconfiscate.

Sat Jul 25 00:00:13 1998  Ross Johnson  <[e-mail]>

	* create.c (_pthread_start_call): Set thread priority.  Ensure our
 	thread entry is removed from the thread table but only if
 	pthread_detach() was called and there are no waiting joins.
	(pthread_create): Set detach flag in thread entry if the 
	thread is created PTHREAD_CREATE_DETACHED.

	changed from -1 to NULL.

Fri Jul 24 23:09:33 1998  Ross Johnson  <[e-mail]>

	* create.c (pthread_create): Change . to -> in sigmask memcpy() args.

	* pthread.h: (pthread_cancel): Add function prototype.
	(pthread_testcancel): Ditto.

1998-07-24  Ben Elliston  <[e-mail]>

	* pthread.h (pthread_condattr_t): Rename dummy st
