2000-01-18  Ulrich Drepper  <drepper@cygnus.com>

2000-01-12  Ulrich Drepper  <drepper@cygnus.com>

	* internals.h (pthread_readlock_info): New structure.
	(_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
	p_untracked_readlock_count.
	* pthread.c (__pthread_initial_thread, pthread_manager_thread):

	* internals.h (struct _pthread_descr_struct): Move new elements to
	the end.

2000-01-03  Kaz Kylheku  <kaz@ashi.footprints.net>

	Redesigned how cancellation unblocks a thread from internal
	cancellation points (sem_wait, pthread_join,
	pthread_cond_{wait,timedwait}).
	Cancellation won't eat a signal in any of these functions
	(*required* by POSIX and Single Unix Spec!).
	* condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
	simultaneous condition variable signal (not required by POSIX
	or Single Unix Spec, but nice).
	* spinlock.c: __pthread_lock queues back any received restarts
	that don't belong to it instead of assuming ownership of lock
	upon any restart; fastlock can no longer be acquired by two threads
	simultaneously.
	* restart.h: Restarts queue even on kernels that don't have
	queued real time signals (2.0, early 2.1), thanks to atomic counter,
	avoiding a rare race condition in pthread_cond_timedwait.

1999-12-31  Andreas Jaeger  <aj@suse.de>

	* internals.h: Remove duplicate prototype declarations.

	* weaks.c: Remove __THROW from prototypes since the file is not

	* wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
	pwrite64, lseek64, open64, and __open64.

	* manager.c (pthread_allocate_stack): Correct computation of
	new_thread_bottom.  Correct handling of stack size and when the
	rlimit method to guard for stack growth is used.
	* pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
	minus one pagesize (not two).

1999-12-03  Andreas Jaeger  <aj@suse.de>

	* Versions: Add __res_state with version GLIBC_2.2.

	* errno.c (__res_state): New function to return thread specific
	resolver state.

	* pthread.c (pthread_initialize): Initialize p_resp.
	(__pthread_reset_main_thread): Also set p_resp.

	* sysdeps/i386/pt-machine.h: Move stack_pointer definition to the
	beginning.
	* sysdeps/i386/i686/pt-machine.h: Likewise.
