mono/mcs/class/corlib/System.Threading/ChangeLog

2009-04-21  Mark Probst  <[email protected]>

	* Thread.cs: Make the execution context field thread-static to
	avoid it being shared between app domains.

2009-04-20  Rolf Bjarne Kvinge  <[email protected]>

	* Thread.cs: For 2.1 ensure exceptions in threads are handled using the
	UnhandledException event mechanism in System.Windows.Application instead
	of crashing the application.

2009-04-18  Mark Probst  <[email protected]>

	* Thread.cs: Don't keep the current number formatter here because
	it's shared between app domains.

2009-04-18  Mark Probst  <[email protected]>

	* Thread.cs: Make the abort exception state a GC handle, to
	properly separate AppDomains.  Add internal method for getting the
	state object.

	* ThreadAbortException.cs: Get the abort exception state via the
	method in Thread.

2009-04-12 Gonzalo Paniagua Javier <[email protected]>

	* WaitHandle.cs: implemented 2 missing WaitAny overloads.

2009-03-05 Rolf Bjarne Kvinge  <[email protected]>

	* WaitHandle.cs: implemented SignalAndWait.

2009-02-18  Jb Evain  <[email protected]>

	* SynchronizationContext.cs: add NET_2_1 SetThreadStaticContext
	method, even if already obsolete.

2009-01-30  Andreia Gaita  <[email protected]>

	* SynchronizationContext.cs: Remove moonlight hacks, dispatcher should
	be able to handle this now.

2008-12-20  Miguel de Icaza  <[email protected]>

	* WaitHandle.cs: Add two overloads that were introduced in 3.5.

2008-11-25  Geoff Norton  <[email protected]>

	* SynchronizationContext.cs: A temporary horrible hack to SyncContext
	to hard-wire all calls back to the main thread (moonlight-only) so that
	we can use our unit test harness.  This will be fixed for 2.1 when we
	implement Dispatcher properly.

2008-10-30 Gonzalo Paniagua Javier <[email protected]>

	* Interlocked.cs: make CompareExchange internal in 1.1 for use by the
	runtime.

2008-09-19  Miguel de Icaza  <[email protected]>

	* WaitHandle.cs (WaitOne): Add new 3.5 SP1 overload.

Tue Sep 16 21:02:59 CEST 2008 Paolo Molaro <[email protected]>

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

	* Timer.cs: use a separate queue for timers that are far in the future
	so they don't need to be looked at as often (bug #418272).
	Better precision of recheduling time.

2008-07-02  Zoltan Varga  <[email protected]>

	* Timer.cs (SchedulerThread): Iterate through the keys of the hashtable instead
	of key-value pairs.

2008-06-18  Kornél Pál  <[email protected]>

	* Thread.cs: Implement BeginThreadAffinity and EndThreadAffinity as no-op
	because managed and native threads are currently bound together.

2008-06-14  Zoltan Varga  <[email protected]>

	* Thread.cs: Sync layout with unmanaged side.

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

	* Monitor.cs: Implement Enter/Exit directly as icalls without managed wrapper
	methods.

2008-04-11  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.

Tue Feb 26 17:51:58 CET 2008 Paolo Molaro <[email protected]>

	* Timer.cs: use a monotonic clock to schedule timers
	(fixes part of bug#347476).

Fri Feb 22 11:23:53 CET 2008 Paolo Molaro <[email protected]>

	* Thread.cs: implemented Begin/EndCriticalRegion.

2008-02-03  Sebastien Pouliot  <[email protected]>

	* WaitHandle.cs: Ifdef out some unused code (found by Gendarme).

2008-01-06  Zoltan Varga  <[email protected]>

	* Thread.cs (set_CurrentCulture): If the culture is read-only, cache the result
	of serializing it.
	(set_CurrentUICulture): Ditto.

2008-01-03  Zoltan Varga  <[email protected]>

	* Thread.cs (set_CurrentCulture): Avoid the serialization overhead if
	the new culture is equal to the old one.

2007-12-27  Zoltan Varga  <[email protected]>

	unmanaged definition.

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

	* ReaderWriterLock.cs : ... and avoid extra finalizer call.

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]>

	* SynchronizationContext.cs : removed SendOrPost().

Wed Oct 17 13:24:33 CEST 2007 Paolo Molaro <[email protected]>

Tue Oct 16 17:22:15 CEST 2007 Paolo Molaro <[email protected]>

	* Timer.cs: remove expired timers from the the jobs list.

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  Dick Porter  <[email protected]>

	Thread.  Patch from [email protected] fixing bugs 325367 and
	325566.

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.

2007-05-09  Jonathan Chambers  <[email protected]>

	* Thread.cs: Implement ApartmentState related items.

2007-05-02  Dick Porter  <[email protected]>

	* WaitHandle.cs (CheckArray): Avoid using reflection unless we
	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]>

	garbage collected if the user doesn't keep a reference to them.

2006-02-09  Miguel de Icaza  <[email protected]>

	* Monitor.cs: Patch from Thong Nguyen, Wait (.., Timeout) method
	should allow a -1 (Timeout.Infinite) to mean indefinite wait (the

	being used in System.Web.Services.

2005-05-26  Sebastien Pouliot  <[email protected]>

	stack propagation).
	* Thread.cs: Made ExecutionContext field accessible from the runtime.
	Added stack propagation when Thread.Start is called.
	* ThreadPool.cs: QueueUserWorkItem now does stack propagation (done in
	the runtime), so I "fixed" UnsafeQueueUserWorkItem not to do so.

2005-05-19  Miguel de Icaza  <[email protected]>

	* Thread.cs: REmove warnings.

2005-05-16 Gonzalo Paniagua Javier <[email protected]>

	does all work.

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
	(Mainsoft). Fixes 74598.

2005-01-27  Sebastien Pouliot  <[email protected]>

	* Overlapped.cs: Added check for ControlPolicy and ControlEvidence for
	Unsafe pack. Added MonoTODO for missing security stack propagation.

	  keep track of threads ready to get the reader lock.

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

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]>

	  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]>

	more fields needed by the runtime.

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

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]>
