2001-10-25	* barrier.c: Move _LONG and _LPLONG defines into	rpj
	implement.h; rename to PTW32_INTERLOCKED_LONG and PTW32_INTERLOCKED_LPLONG respectively. * spin.c: Likewise; ptw32_interlocked_compare_exchange used in place of InterlockedCompareExchange directly. * global.c (ptw32_interlocked_compare_exchange): Add prototype for this new routine pointer to be used when InterlockedCompareExchange isn't supported by Windows. * nonportable.c (pthread_win32_process_attach_np): Check for support of InterlockedCompareExchange in kernel32 and assign its address to ptw32_interlocked_compare_exchange if it exists, or our own ix86 specific implementation ptw32_InterlockedCompareExchange. private.c (ptw32_InterlockedCompareExchange): An implementation of InterlockedCompareExchange() which is specific to ix86; written directly in assembler for either MSVC or GNU C; needed because Windows 95 doesn't support InterlockedCompareExchange(). sched.c (sched_get_priority_min): Extend to return THREAD_PRIORITY_IDLE. (sched_get_priority_max): Extend to return THREAD_PRIORITY_CRITICAL.
2001-07-18	Fix potential NULL pointer dereferences.	rpj
	Contributed by - "Scott McCaskill" <scott@magruder.org> * mutex.c (pthread_mutexattr_init): Return ENOMEM immediately and don't dereference the NULL pointer if calloc fails. (pthread_mutexattr_getpshared): Don't dereference a pointer that is possibly NULL. * barrier.c (pthread_barrierattr_init): Likewise (pthread_barrierattr_getpshared): Don't dereference a pointer that is possibly NULL. * condvar.c (pthread_condattr_getpshared): Don't dereference a pointer that is possibly NULL.
2001-07-11	Fixed cast; tests passed.	rpj

2001-07-10	Untested revamp of barrier.c.	rpj
	* barrier.c: Still more revamping. The exclusive access mutex isn't really needed so it has been removed and replaced by an InterlockedDecrement(). nSerial has been removed. iStep is now dual-purpose. The process shared attribute is now stored in the barrier struct. * implement.h (pthread_barrier_t_): Lost some/gained one elements. * private.c (ptw32_threadStart): Removed some comments.
2001-07-09	* barrier.c: Revamped to fix the race condition. Two alternating	rpj
	semaphores are used instead of the PulseEvent. Also improved overall throughput by returning PTHREAD_BARRIER_SERIAL_THREAD to the first waking thread. * implement.h (pthread_barrier_t_): Revamped.
2001-07-08	Barriers fixed and tested more extensively.	rpj
	* barrier.c: Fix several bugs in all routines. Now passes tests/barrier5.c which is fairly rigorous. There is still a non-optimal work-around for a race condition between the barrier breeched event signal and event wait. Basically the last (signalling) thread to hit the barrier yields to allow any other threads, which may have lost the race, to complete. tests/ChangeLog: * barrier3.c: Fixed. * barrier4.c: Fixed. * barrier5.c: New; proves that all threads in the group reaching the barrier wait and then resume together. Repeats the test using groups of 1 to 16 threads. Each group of threads must negotiate a large number of barriers (10000). * spin4.c: Fixed. * test.h (error_string): Modified the success (0) value.
2001-07-06	Spinlocks and barriers fixed and working. Beta level.	rpj
	* spin.c: Revamped and working; included static initialiser. * barrier.c: Likewise. * condvar.c: Macro constant change; inline auto init routine. * mutex.c: Likewise. * rwlock.c: Likewise. * private.c: Add support for spinlock initialiser. * global.c: Likewise. * implement.h: Likewise. * pthread.h (PTHREAD_SPINLOCK_INITIALIZER): Fix typo. tests/ChangeLog: * spin3.c: Changed test and fixed. * spin4.c: Fixed. * barrier3.c: Fixed. * barrier4.c: Fixed.
2001-07-05	Fixups to last commit.	rpj

2001-07-05	* barrier.c: Remove static initialisation - irrelevent	rpj
	for this object. * pthread.h (PTHREAD_BARRIER_INITIALIZER): Removed. * rwlock.c (pthread_rwlock_wrlock): This routine is not a cancelation point - disable deferred cancelation around call to pthread_cond_wait(). tests/ChangeLog: * spin1.c: New; testing spinlocks. * spin2.c: New; testing spinlocks. * spin3.c: New; testing spinlocks. * spin4.c: New; testing spinlocks. * barrier1.c: New; testing barriers. * barrier2.c: New; testing barriers. * barrier3.c: New; testing barriers. * barrier4.c: New; testing barriers. * GNUmakefile: Add new tests. * Makefile: Add new tests.
