2012-03-20	Clean up unnecessary prototypes. Pointed out by brad@	Philip Guenthe

2012-03-20	Permit recursive locking in _rthread_dl_lock(), as an so's destructor	Philip Guenthe
	may need to call dlclose(). problem observed by Antti Harri (iku at openbsd.fi), ok kurt@
2012-03-14	Force sched_yield() to be resolved before calling dlctl(DL_SET*LCK) with	Philip Guenthe
	a function that can call sched_yield(), to avoid recursion ok kurt@ kettenis@
2012-03-13	Don't trust the environment if issetugid()	Philip Guenthe

2012-03-03	Sync the assembly statements with <machine/lock.h> for consistency.	Miod Vallat

2012-03-03	Bump minor for recent additions	Philip Guenthe

2012-03-03	sem_timedwait() should return ETIMEDOUT instead of EWOULDBLOCK on timeout	Philip Guenthe

2012-03-03	Add sem_timewait() and fix sem_wait()'s handling of signals, so	Philip Guenthe
	that it resumes waiting unless the thread was canceled. As part of this, change the internal _sem_wait() function to return zero on success and an errno value on failure instead of 1 on success and zero on failure.
2012-03-02	fix check when setting the contention scope. harmless atm but still wrong.	Federico G. Schwindt
	guenther@ ok.
2012-03-02	for readability, put the label on it's own line.	Federico G. Schwindt

2012-03-02	_SPINLOCK_UNLOCKED isn't zero everywhere (coughhppacough), so	Philip Guenthe
	sem_init() can't assume that calloc will leave the embedded spinlock in the unlocked state ok miod@ otto@
2012-02-28	Our default mutex type is PTHREAD_MUTEX_ERRORCHECK, for which trying	Philip Guenthe
	to unlock an uninitialized mutex is required to return EPERM, so add the necessary checks. For recursive mutexes, return an error from pthread_mutex_lock() if the count would overflow. problem observed in glib testing by aja@
2012-02-27	fix __errno symbol name	Miod Vallat

2012-02-26	Fix buglets.	Miod Vallat

2012-02-26	__cerror gets invoked with errno in v0, not a0.	Miod Vallat

2012-02-26	Fix label for threaded binaries to link.	Miod Vallat

2012-02-24	sched_yield() is the standard name while pthread_yield() is the	Philip Guenthe
	non-standard alias, so prefer the former
2012-02-23	PTHREAD_MUTEX_NORMAL mutexes are supposed to self-deadlock, not abort.	Philip Guenthe
	That deadlock can be exited via a timeout for pthread_mutex_timedlock(). Unwind all the state when pthread_mutex_timedlock() times out
2012-02-23	Add pthread_condattr_{get,set}clock(), requested by aja@	Philip Guenthe
	Add pthread_mutex_timedlock(), requested by dcoppa@
2012-02-21	Make pthread_suspend_np() and pthread_resume_np() simply fail instead	Philip Guenthe
	of doing the Wrong Thing.
2012-02-19	Fix problems revealed by regress/lib/libpthread/stack/stack.c	Philip Guenthe

2012-02-19	Use 'base' as an intermediate char* variable to avoid void* arithmetic	Philip Guenthe

2012-02-19	Extend miod's fix CFLAGS fix to all gcc2 platforms (suggested by Tobias	Philip Guenthe
	Ulmer). Only pull in bsd.lib.mk once to avoid linking objects twice
2012-02-19	Use a form of designated initializer that works with gcc2	Philip Guenthe
	lint doesn't understand designated initializers, so hide them from it
2012-02-19	Validate in pthread_attr_set{scope,sched{param,policy},inheritsched}()	Philip Guenthe
	the requested new value
2012-02-18	Fix previous commit: _rthread_init() was static.	Philip Guenthe
	Improve consistency of error naming
2012-02-18	Before using _thread_pagesize, make sure _rthread_init() has been called	Philip Guenthe

2012-02-18	id tag.	Federico G. Schwindt

2012-02-18	Fix the handling of the stackaddr, stacksize, and guardsize attributes:	Philip Guenthe
	don't try to merge values, round the sizes separately, and don't try to unmap application-supplied stacks. Copy from uthread the caching of default-sized stacks. Have pthread_attr_init() and pthread_create() get the default attributes from staticly allocated pthread_attr_t. Cache the pagesize in _rthread_init() and provide a macro for rounding to it based on suggestions from kettenis@ and tedu@, ok kettenis@
2012-02-18	Missing cerror bits.	Miod Vallat

2012-02-18	Work around compiler confusion while building rthread.o on vax.	Miod Vallat

2012-02-18	Initialize the scope, policy, and inherit members in pthread_attr_init()	Philip Guenthe
	so that their pthread_attr_get* don't return bogus values. issue noted and tested by aja@
2012-02-17	Allow librthread to build on mips64.	Miod Vallat

2012-02-16	Set __isthreaded in pthread_create() instead of _rthread_init() such that it	Mark Kettenis
	properly represents whether a process is multi-threaded or not. This fixes a bug where if a forked child would create a new thread we would not set __isthreaded. ok guenther@
2012-02-15	Nothing important, just switching from pthreads to rthreads	Philip Guenthe

2012-02-15	Bump major to be current libpthread major +1, so we can switch over cleanly.	Philip Guenthe
	If we have to revert to user-space threads, we'll do another major bump of libpthread going back
2012-02-15	Add pthread_rwlockattr_{get,set}pshared() and	Philip Guenthe
	pthread_mutexattr_{get,set}kind_np() tweaked diff from brad
2012-01-25	@($*& Merging patches resulted in a line being duplicated instead of	Philip Guenthe
	moved. Unlocking a spinlock twice is bad, mmkay?
2012-01-17	Reimplement mutexes, condvars, and rwlocks to eliminate bugs,	Philip Guenthe
	particularly the "consume the signal you just sent" hang, and putting the wait queues in userspace. Do cancellation handling in pthread_cond_wait(), pthread_join(), and sem_wait(). Add __ prefix to thr{sleep,wakeup,exit,sigdivert}() syscalls; add 'abort" argument to thrsleep to close cancellation race; make thr{sleep,wakeup} return errno values via retval to avoid touching userspace errno.
2012-01-04	Fix $OpenBSD tag	Philip Guenthe

2012-01-04	Add some sanity checks, set errno accordingly to POSIX and add the named	Martin Pieuchot
	semaphore stubs already provided by libpthread. We may move them in their own file in the future when we figure out a real implementation. Discussed with and looks ok to guenther@
2012-01-04	Split out the semaphore functions.	Martin Pieuchot
	ok guenther@
2012-01-04	Delete some parameter names and extra semicolons that slipped through	Philip Guenthe

2011-12-28	pthread_self() may be much cheaper and never more expensive than getthrid()	Philip Guenthe
	so prefer it for identifying the current thread
2011-12-27	Don't let applications block, wait for, or handle SIGTHR, as the	Philip Guenthe
	thread library uses it internally for cancellation.
2011-12-27	On failure, pthread_kill() should return the errno, not -1	Philip Guenthe

2011-12-24	formatting errors, found using freebsd's "igor";	Jason McIntyre

2011-12-22	Add pthread_mutex_{get,set}prioceiling()	Philip Guenthe

2011-12-21	Split out the pthread_rwlock* and pthread_once() functions from rthread_sync.c	Philip Guenthe
	to new files rthread_rwlock.c, rthread_rwlockattr.c, and rthread_once.c
2011-12-21	Split out the pthread_mutexattr_* functions from rthread_sync.c to	Philip Guenthe
	new file rthread_mutexattr.c. Add basic implementations of pthread_mutexattr_{set,get}{protocol,prioceiling} Requested by aja
