Clear the thread state after finishing a work item. We were only
	resetting the background state.

Bump the size of the epoll threads to 256k on 64 bit systems to avoid problems on ppc64 with 64k page sizes.

	AppDomainUnloadedException is also ignored when thrown in a threadpool
	thread.

	* threadpool.c: ignore ThreadAbortException when it is unhandled in a
	threadpool thread.

	* threadpool.c: the calls to wsq_create, wsq_destroy and wsq_cleanup
	are inside a lock now to avoid race conditions upon shut down. Fixes
	bug #625359.

	* mono/tests/threadpool-exceptions[1-4].cs: new tests
	* mono/tests/threadpool.cs: fix typo.
	* mono/metadata/threadpool.c: starting in .NET 2.0, unhandled exceptions
	in the threadpool can cause a crash in a running program. From now on,
	we are compatible.

These exception were being thrown, sometimes, in a threadpool thread and then
ignored.

Until now exceptions thrown from a threadpool work item were ignored.
From now on they will propagate to the domain's UnhandledException event
and then to the root AppDomain. If they are not handled, they will cause
the program to abort.

	* threadpool.c: use a monitor thread to start up new ones when needed.
	Fixes bug #622398.

	* threadpool.c: Fix the DISABLE_SOCKETS build.

svn path=/trunk/mono/; revision=157708

	* threadpool.c: patch from Robert Nagy that fixes a nullref and
	uses mono_sem_wait instead of mono_sem_timedwait for openbsd.


svn path=/trunk/mono/; revision=156012

	* domain-internals.h: made threadpool_jobs volatile.
	* mono-wsq.c: add an assert to verify that the threadpool cleaned up
	all local jobs.
	* threadpool.c:
		-When two threads try to initialize the socket IO pool,
		the second one waits until the intialization is finished
		instead of continuing right away.
		-Add checks for domain unload: no items added in this case.
		-Only measure the time every 10 elements added to the queue.
		This is an experiment since linux x86 gettimeofday() sucks.
		-Create new thread if there are none waiting for work items.
		-There was a missing decrement of the busy threads.
		-Make sure the local queue is cleaned up before exiting the
		thread when the program ends.

	* threadpool.c: don't attempt to close the pipe when it has not been
	created.


svn path=/trunk/mono/; revision=154820

svn path=/trunk/mono/; revision=154812

	* threadpool.c: if there are no waiting threads, try to start a new
	one. This fixes the not-so-random hangs in System.ServiceModel tests.
	No need to use InterlockedCompareExchange to read volatile variables.


svn path=/trunk/mono/; revision=154811

	* threadpool.c: threadpool threads wait is alertable.
	Fixes bug #592264.
	Reduced the stack size of the *poll_wait thread.


svn path=/trunk/mono/; revision=154645

	* threadpool.c: don't try executing items from domains being
	unloaded. Fixes appdomain-async-invoke test.


svn path=/trunk/mono/; revision=154324

	* threadpool.c: spin while the threadpool initializes.
	* mono-wsq.c: if the WSQ has not been initialized or has been shut
	down, don't do anything.


svn path=/trunk/mono/; revision=154321

	* threadpool.c: reset 'state' to avoid returning non-null when the
	event type is not found.

	* mempool.c, class-internals.h, class.c, icall.c, metadata.c,
	object-internals.h, object.c, reflection.c, threadpool.c:
	reduce resource usage when the small config is selected.
	In particular, up to 64K of methods/fields/properties/events
	are allowed and "other" methods in events are ignored.

	* appdomain.c, domain.c, icall.c, image.c, marshal.c, object.c,
	reflection.c, socket-io.c, threadpool.c, threads.c: removed 1.1/1.0
	support.

svn path=/trunk/mono/; revision=146644

	* threadpool.[ch]: added hooks for thread start/finish and item
	processing begin/end. For monotouch use only.


svn path=/trunk/mono/; revision=144807

svn path=/trunk/mono/; revision=144416

	* threadpool.c: one more...


svn path=/trunk/mono/; revision=143285

	* threadpool.c: forgot a LeaveCriticalSection when telling the idle
	threads to die because we're shutting down. delgate5.exe works again.


svn path=/trunk/mono/; revision=143284

svn path=/trunk/mono/; revision=142928

	* threadpool.c: fixed the order in which 'completed' and the wait
	handle, if any, are set.  Fixes bug #542933 and delegate2.exe
	No need to use the wait_handle field of ASyncCall. Make sure the
	threadpool is active when adding a job or queueing an idle thread.


svn path=/trunk/mono/; revision=142927

	* sgen-gc.c: New debug option "xdomain-checks", which scans the
	whole heap for cross-domain references before each collection.

	* sgen-scan-object.h: The scan action can now use SCAN to scan the
	object.

	* threadpool-internals.h, threadpool.c: New function
	mono_thread_pool_is_queue_array() for checking whether a given
	array is used as a (cross-domain) queue by the thread pool code.

svn path=/trunk/mono/; revision=142674

	* threadpool.c:
	* class-internals.h:
	* mono-perfcounters-def.h:
	* mono-perfcounters.c:
	-There is a list of idle threads
	-Each of those idle threads wait on their own WaitHandle instead
	of all of them using the same semaphore. When a new work item is
	added, the job is assigned directly to an idle thread or a newly
	created one if possible and then the handle for that thread is
	signaled. Compare that to the current approach where all the
	threads in the pool compete to dequeue a job from the same
	queue.
	-New struct ThreadPool that brings together the bunch of static
	variable for each threadpool (IO and regular).
	-New performance counters: # of items added and its rate per
	threadpool. The rate will be used later, perhaps together with
	other perf. counters, to decide when idle threads should exit.


svn path=/trunk/mono/; revision=142667

	* object-internals.h: The Thread class is split up into Thread and
	InternalThread now.  We have exactly one InternalThread per
	thread, and at most one Thread per appdomain per thread.  Most
	data is stored in InternalThread.  All InternalThread objects live
	in the root domain.

	* class-internals.h: Add internal_thread_class to MonoDefaults.

	* appdomain.c (mono_domain_unload), attach.c (receiver_thread),
	domain.c, gc.c, icall-def.h, monitor.c, object.c, sgen-gc.c,
	socket-io.c, threadpool.c, thread-types.h, threads.c: Changes
	resulting from the split of the Thread class.

	* gc-internal.h: Prototype for new function for checking whether a
	thread is the finalizer thread.

	* appdomain.c: Corlib version bump.

2009-09-25  Mark Probst  <mark.probst@gmail.com>

	* method-to-ir.c, mini.h, mini-alpha.c, mini-amd64.c, mini-arm.c,
	mini-hppa.c, mini-ia64.c, mini-mips.c, mini-ppc.c, mini-s390.c,
	mini-s390x.c, mini-sparc.c, mini-x86.c: Thread.get_CurrentThread
	works differently now and we don't handle it in the JIT anymore.

	* mini.c, mini-exceptions.c, mini-posix.c, debug-debugger.c,
	debug-mini.c, tramp-amd64.c, tramp-x86.c: Changes resulting from
	the Thread class split.

2009-09-25  Mark Probst  <mark.probst@gmail.com>

	* xdomain-threads.c: Test for checking whether Thread is correctly
	separated between appdomains.

	* Makefile.am: Test added.

svn path=/trunk/mono/; revision=142662

	* threadpool.c: actually use the minimum number of 'completion ports'
	(for us is just a potential worker thread).


svn path=/trunk/mono/; revision=142379

	* threadpool.c: remove ares_htable. It does not make sense any more
	since the same objects are now stored in GC-tracked arrays while they are
	in the queue.


svn path=/trunk/mono/; revision=142378

	* threadpool.c: increase the minimum length of the queues to 128.
	Remove warning.


svn path=/trunk/mono/; revision=142377

	* threadpool.c: make the Sleep() alertable to prevent delays exiting
	applications that take less than 2s to execute.
	Bug #524984 fixed.


svn path=/trunk/mono/; revision=141363

	* mono-hash.c: When creating a hash table, if the keys are managed
	objects, assert that we have a hash function.  Remove the
	rehashing after GC marking.

2009-08-21  Mark Probst  <mark.probst@gmail.com>

	* threadpool.c (mono_thread_pool_init): Use mono_object_hash() as
	the hash function for the ares_htable.
