Tue Sep 9 15:19:48 CEST 2008 Paolo Molaro <[email protected]>

2008-06-07  Zoltan Varga  <[email protected]>

	  thread so it can reused for performint ToString conversions.

2008-03-26  Massimiliano Mantione <[email protected]>
	* Thread.cs: Renamed "unused6" because it will be used to hold
	the "mono_thread_manage" callback.

2007-11-20  Atsushi Enomoto  <[email protected]>

	* ReaderWriterLock.cs : adding missing 2.0 destructor (does nothing).

Thu Nov 8 18:36:25 CET 2007 Paolo Molaro <[email protected]>

	* Timer.cs: if period is 0 with a non-infinite due time, we
	run the callback just once (bug #340212).

2007-10-24  Dick Porter  <[email protected]>

	* Thread.cs: Call Thread_init on the new 2.0 constructors too.

2007-10-24  Dick Porter  <[email protected]>

	* Thread.cs: Assign the ManagedThreadId when it is asked for,
	rather than in the constructor, so ThreadPool threads also work.
	Fixes bug 335579 (and doesn't break 325367 or 325566)

2007-10-24  Atsushi Enomoto  <[email protected]>

Tue Oct 16 12:14:43 CEST 2007 Paolo Molaro <[email protected]>

	* Timer.cs: rewrote to use threadpool threads to invoke the callbacks,
	avoid Thread.Abort and Thread.Interrupt and use a single scheduler
	thread, partially from the patch of Rafael Ferreira in bug #315999.
	Fixes bug #315999, #332206.

2007-10-15  Dick Porter  <[email protected]>

	* Thread.cs: Initialise synch_cs to null now we aren't using it as
	a monitor lock

2007-09-25  Jonathan Pobst  <[email protected]>

	* SynchronizationContext.cs: Implement SetSynchronizationContext.

2007-09-06  Dick Porter  <[email protected]>

	* Timer.cs: Only hold a WeakReference to the runner thread, to
	work around an issue when finalizing at shutdown or (I think)
	appdomain unload.  (Basically, the Thread was being finalized
	first, but the Timer's finalizer was still trying to reference it
	subsequently.)

2007-08-10  Gert Driesen  <[email protected]>

	* Thread.cs: Throw ThreadStateException when retrieving ApartmentState
	or IsBackground if thread is stopped. Fixes bug #81658.

2007-08-08  Zoltan Varga  <[email protected]>

	* Thread.cs: Add a fixme.

2007-07-21  Miguel de Icaza  <[email protected]>

	* WaitHandle.cs (Handle): It turns out that we should never create
	new SafeWaitHandles, as applications will assume that a
	SafeWaitHandle pulled from this will be the same after a Handle
	update (from Gert's test):

	
                AutoResetEvent are1 = new AutoResetEvent (false);
                AutoResetEvent are2 = new AutoResetEvent (false);
                SafeWaitHandle swh1 = are1.SafeWaitHandle;
                Console.WriteLine ("#A1:" + !swh1.IsClosed);
                Console.WriteLine ("#A2:" + !swh1.IsInvalid);
                IntPtr dummyHandle = (IntPtr) 2;
                are1.Handle = dummyHandle;
                Console.WriteLine ("#A3:" + (are1.Handle == dummyHandle));
                Console.WriteLine ("#A4:" + !swh1.IsClosed);
                Console.WriteLine ("#A5:" + !swh1.IsClosed);
                Console.WriteLine ("#A6:" + !swh1.IsInvalid);
                Console.WriteLine ("#A7:" + !are1.SafeWaitHandle.IsClosed);
                Console.WriteLine ("#A8:" +
	        !are1.SafeWaitHandle.IsInvalid);

	We would return in A4, A5, A6 true, even when we have set the
	Handle ourselves. 

	* 

2007-07-18  Miguel de Icaza  <[email protected]>

	* WaitHandle.cs (Handle): in the 2.0 profile, explicitly dispose
	the old SafeWaitHandle, do not wait for the finalizer to run;

	Take ownership of the handle;   The docs did not say that
	assigning to this value would lead to a leak, the docs said that
	in the 1.0 and 1.1 profiles assigning to this property might lead
	to a leak.   My mistake. 

	Fixes: 82134
	
2007-07-09  Atsushi Enomoto  <[email protected]>

	* LockCookie.cs, AsyncFlowControl.cs :
	  added missing operator == and !=.

2007-05-22  Jonathan Chambers  <[email protected]>

	* Thread.cs: Use & to check ThreadState rather than ==.
	Fixes AlbumSurfer regression.

	really need to.

2006-06-29  Duncan Mak  <[email protected]>

	* WaitHandle.cs (CheckArray): Throw NotSupportedException if the
	current thread is marked with the STAThreadAttribute. Fixes bug
	#78455.

2006-05-05  Sebastien Pouliot  <[email protected]>

2005-05-11  Sebastien Pouliot  <[email protected]> 

	* CompressedStack.cs: Allow merging of an existing CompressedStack
	with the actual stack of the current Thread.
	* Thread.cs: GetCompressedStack and SetCompressedStack are public 
	before 2.0 but couldn't be seen with mono-api-info because of it's 
	LinkDemand for the ECMA public key. Removed unused CompressedStack
	private field (now part of the ExecutionContext).

2005-05-09  Sebastien Pouliot  <[email protected]> 

	* CompressedStack.cs: GetCompressedStack is public before 2.0 but 
	couldn't be seen with mono-api-info because of it's LinkDemand for
	the ECMA public key. Stack capture occurs here if none exists on the
	current thread.

2005-04-28 Gonzalo Paniagua Javier <[email protected]>

	* ReaderWriterLock.cs: fix random ApplicationException errors. Tested
	with the System.Web.Cache stress program. Patch by Eyal Alayuf

	  Added internal interruption_requested field.

2004-05-13  Sebastien Pouliot  <[email protected]>

	* CompressedStack.cs: Added an internal constructor so a default one
	doesn't appear with corcompare.
	* Thread.cs: Added missing MemoryBarrier (only for 1.1) and SpinWait to please
	corcompare. Both throw a NotImplementedException.

	In Dispose, notify the WaitHandle.

2004-04-11  Lluis Sanchez Gual <[email protected]>

	* ReaderWriterLock.cs: More fixes: never wait where acquiring a reader lock
	  if the thread already has the lock. Added readyWaitingReaders variable to
	  keep track of threads ready to get the reader lock.

2004-04-11  Lluis Sanchez Gual <[email protected]>

	* LockQueue.cs: Moved lockCount change inside the rwlock lock. Removed
	  lock(this) when entering the rwlock to avoid a deadlock.

2004-04-08  Lluis Sanchez Gual <[email protected]>

	* ReaderWriterLock.cs: Changed some methods to private.
	* WaitHandle.cs: In Wait methods, release the synchronization context when 
	  exitContext is true.

2004-04-08  Gonzalo Paniagua Javier <[email protected]>

	* Timer.cs: call Abort on the Runner instance too.

2004-04-07  Jackson Harper  <[email protected]>

	* Thread.cs: Use new culture info method for constructing the
	current culture.
	
2004-04-07  Lluis Sanchez Gual <[email protected]>

	* ReaderWriterLock.cs: When a thread holds a writer lock, a call to
	  AcquireReaderLock works like a call to AcquireWriterLock.

2004-04-06  Lluis Sanchez Gual <[email protected]>

	* Monitor.cs: In Wait(), release the synchronization context when 
	  exitContext is true.

2004-04-06  Lluis Sanchez Gual <[email protected]>

	* LockCookie.cs: Keep in this class the count of reader or writer locks
	  for a thread, not only whether it has locks or not.
	* LockQueue.cs: Added property for checking if a thread is waiting in
	  the queue. Wait now returns a boolean that set to false on timeout 
	  expiration.
	* ReaderWriterLock.cs: Started fixing bugs but I had to rewrite a lot of it.
	  The main change is that now it keeps a reader lock count for each
	  thread. This is needed since methods like ReleaseLock or

	  Also added support for recursive writer-lock requests.

2004-03-21  Gonzalo Paniagua Javier <[email protected]>

	* ThreadAbortException.cs: use same HResult as MS.

	FreeNamedDataSlot.

Wed Aug 20 12:01:36 CEST 2003 Paolo Molaro <[email protected]>

	* Thread.cs: put all the fields at the start and add
	more fields needed by the runtime.

2003-08-14  Lluis Sanchez Gual  <[email protected]>

	  if a dataslot has been allocated (value could be null).

2003-07-23  Duncan Mak  <[email protected]>

	milliseconds.

	* WaitHandle.cs: fixes for WaitAny/All and TimeSpan.

2003-06-06  Gonzalo Paniagua Javier <[email protected]>

	* WaitHandle.cs: checks and exceptions.

2003-06-02  Gonzalo Paniagua Javier <[email protected]>

	* WaitHandle.cs: call CloseEvent_internal when disposing.

2003-05-31  Gonzalo Paniagua Javier <[email protected]>

	* RegisteredWaitHandle.cs: check that the callback is not null before
	invoking.

	* ThreadPool.cs: fixed timeout -> TimeSpan conversions (closes bug
	#43963). Queue the item before setting the handle. If there's a timeout,
	avoid trying to Dequeue, getting the exception et al, just continue the
	loop.

Mon May 19 09:07:45 CEST 2003 Paolo Molaro <[email protected]>

	before the "if" that ensures the integrity. After this, the first of
	that two lines was producing a NullReferenceException.

2003-04-09  Dick Porter  <[email protected]>

	* Thread.cs: Make sure a reference to the ThreadStart delegate is
	held.  There's no telling how long it will be before
	Thread.Start() is called, and GC might destroy the delegate.
	Thread() and Start() need to be rewritten so that the runtime
	creates the new thread when Start() is called, which will simplify
	the code a great deal.

2003-03-20  Miguel de Icaza  <[email protected]>

	* Thread.cs (CurrentCuluture): use the invaraint culture instead
	of "" for the current_culture setting.

	ms, not Milliseconds.

2002-12-07  Martin Baulig  <[email protected]>

	* Timer.cs: Make it actually work; now it no longer sets your
	application on fire if you use a zero periode and Timer.Change()
	actually works.

2002-11-11  Gonzalo Paniagua Javier <[email protected]>

	* Timer.cs: implemented more stuff. It works now.

2002-10-25  Zoltan Varga  <[email protected]>

	* Thread.cs: Implement GetDomain() and GetDomainID().

2002-10-24  Gonzalo Paniagua Javier <[email protected]>

	* ThreadPool.cs: now the monitor thread is not sleeping and checking if
	more worker threads needed. It waits on _DataInQueue. If (and only if)
	there's data in the queue it checks if more worker threads needed and
	then sleeps 0.5s before waiting for queued data again.

2002-09-28  Gonzalo Paniagua Javier <[email protected]>

	internal calls.

2001-11-26  Dick Porter  <[email protected]>

	* Thread.cs: DataSlot uses a single system TLS slot, and a
	hashtable per thread.  Some minor changes to reflect the new
	internal calls using the new IO library, and the newly-supported
	bool returns from internal calls.

	* Monitor.cs: Use bool returns from internal calls now they are
	supported by the runtime.  Coalesce enter with the try_enter
	internal call.

Wed Nov 14 17:06:18 CET 2001 Paolo Molaro <[email protected]>
