Changes since the last snapshot
-------------------------------
-----------------------------------
-New: Spin locks (beta level code)
-----------------------------------
-These are part of POSIX 1003.1j.
-
- #define _POSIX_SPIN_LOCKS
- pthread_spin_init()
- pthread_spin_destroy()
- pthread_spin_lock()
- pthread_spin_unlock()
- pthread_spin_trylock()
- PTHREAD_SPINLOCK_INITIALIZER
-
-Spin_lock spins (busy-waits) if more than one processor is available
-to the process, othewise it is equivalent to a POSIX_MUTEX_DEFAULT
-mutex. The spinlock routines do minimal error checking.
-
---------------------------------
-New: Barriers (beta level code)
---------------------------------
-These are part of POSIX 1003.1j.
-
- #define _POSIX_BARRIERS
- pthread_barrier_init()
- pthread_barrier_destroy()
- pthread_barrier_wait()
- pthread_barrierattr_init()
- pthread_barrierattr_destroy()
- pthread_barrierattr_getpshared()
- pthread_barrierattr_setpshared()
+rwlocks
+-------
+Restored pthread_rwlock_wrlock() as a cancelation point as permitted
+by POSIX 1003.1j. (Was prematurely disabled in the the last snapshot.)
----------
Bug fixes
---------
-In pthread_mutex_lock, return the error if an
-auto-initialiser initialisation fails.
-
-_POSIX_READER_WRITER_LOCKS is now defined.
+Fixed potential NULL pointer dereferences in pthread_mutexattr_init,
+pthread_mutexattr_getpshared, pthread_barrierattr_init,
+pthread_barrierattr_getpshared, and pthread_condattr_getpshared.
+- Scott McCaskill <scott@magruder.org>
-pthread_rwlock_wrlock() was a cancelation point.
