Sun Oct 11 22:44:55 1998  Ross Johnson  <[e-mail]>

	* global.c (_pthread_tsd_key_table): Add new global.

	* implement.h (_pthread_tsd_key_t and struct _pthread_tsd_key):
	Add.
	(struct _pthread): Remove destructorstack.

 	global rather than per-thread. No longer removes destructor nodes
	from the stack. Comments updated.

1998-10-06  Ben Elliston  <[e-mail]>

	* condvar.c (cond_wait): Use POSIX, not Win32 mutex calls.
	(pthread_cond_broadcast): Likewise.
	(pthread_cond_signal): Likewise.

1998-10-05  Ben Elliston  <[e-mail]>

	* pthread.def: Update. Some functions aren't available yet, others
	are macros in <pthread.h>.

	* tests/join.c: Remove; useless.

Mon Oct  5 14:25:08 1998  Ross Johnson  <[e-mail]>

	* pthread.def: New file for building the DLL.

1998-10-05  Ben Elliston  <[e-mail]>

	* misc.c (pthread_equal): Correct inverted logic bug.
	(pthread_once): Use the POSIX mutex primitives, not Win32. Remove
	irrelevant FIXME comment.

	* global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h.

	* pthread.h (PTHREAD_MUTEX_INITIALIZER): Define.
	(pthread_mutex_t): Reimplement as a struct containing a valid
	flag. If the flag is ever down upon entry to a mutex operation,
	we call pthread_mutex_create() to initialise the object. This
	fixes the problem of how to handle statically initialised objects
	that can't call InitializeCriticalSection() due to their context.
	(PTHREAD_ONCE_INIT): Define.

	* mutex.c (pthread_mutex_init): Set valid flag.
	(pthread_mutex_destroy): Clear valid flag.
	(pthread_mutex_lock): Check and handle the valid flag.
	(pthread_mutex_unlock): Likewise.
	(pthread_mutex_trylock): Likewise.

	* tests/mutex3.c: New file; test for the static initialisation
	macro. Passes.

	* tests/create1.c: New file; test pthread_create(). Passes.
	
	* tests/equal.c: Poor test; remove.
	
	* tests/equal1.c New file; test pthread_equal(). Passes.

	* tests/once1.c: New file; test for pthread_once(). Passes.

	* tests/self.c: Remove; rename to self1.c.

	* tests/self1.c: This is the old self.c.

	* tests/self2.c: New file. Test pthread_self() with a single
	thread. Passes.

	* tests/self3.c: New file. Test pthread_self() with a couple of
	threads to ensure their thread IDs differ. Passes.
	
1998-10-04  Ben Elliston  <[e-mail]>

	* tests/mutex2.c: Test pthread_mutex_trylock(). Passes.

	* tests/mutex1.c: New basic test for mutex functions (it passes).
	(main): Eliminate warning.

	* configure.in: Test for __stdcall, not _stdcall. Typo.

	* configure: Regenerate.

	* attr.c (pthread_attr_setstackaddr): Remove FIXME comment. Win32
	does know about ENOSYS after all.
	(pthread_attr_setstackaddr): Likewise.

1998-10-03  Ben Elliston  <[e-mail]>

	* configure.in: Test for the `_stdcall' keyword.  Define `STDCALL'
	to `_stdcall' if we have it, null otherwise.

	* configure: Regenerate.

	* acconfig.h (STDCALL): New define.

	* config.h.in: Regenerate.

	* create.c (_pthread_start_call): Add STDCALL prefix.
	
	* mutex.c (pthread_mutex_init): Correct function signature.

	* attr.c (pthread_attr_init): Only zero out the `sigmask' member
	if we have the sigset_t type.

	* pthread.h: No need to include <unistd.h>.  It doesn't even exist
	on Win32! Again, an artifact of cross-compilation.	
	(pthread_sigmask): Only provide if we have the sigset_t type.

	* process.h: Remove. This was a stand-in before we started doing
	native compilation under Win32.

	* pthread.h (pthread_mutex_init): Make `attr' argument const.

1998-10-02  Ben Elliston  <[e-mail]>

	POSIX TSD on top of Win32 TLS.

1998-09-12  Ben Elliston  <[e-mail]>

	* signal.c (pthread_sigmask): Only provide if HAVE_SIGSET_T is
	defined.
 
	* config.h: #undef features, don't #define them.  This will be
	generated by autoconf very soon.
	
1998-08-11  Ben Elliston  <[e-mail]>

	* Makefile (LIB): Define.
	(clean): Define target.
	(all): Build a library not just the object files.

	* pthread.h: Provide a definition for struct timespec if we don't
	already have one.

	* windows.c (TlsGetValue): Bug fix.
