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

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.
	* ThreadPool.cs: Added missing UnsafeRegisterWaitForSingleObject methods (4
	overloads) to please corcompare. All throw a NotImplementedException.

2004-05-12  Zoltan Varga  <[email protected]>

	* CompressedStack.cs: New file.

2004-04-15  Lluis Sanchez Gual <[email protected]>

	* ThreadPool.cs: Added GetMinThreads and SetMinThreads.
	* Timer.cs: In Change, return false if the timer has been disposed.
	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.
	* ReaderWriterLock.cs: In AcquireWriterLock, queue the thread if the queue
	  is not empty (even if state==0).

2004-04-09  Zoltan Varga  <[email protected]>

	* Timer.cs: Call the callback immediately if dueTime is 0. Fixes
	#56728.

2004-04-08  Jackson Harper  <[email protected]>

	* ReaderWriterLock.cs: Fix tyop
	
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 
	  UpgradeToWriterLock need to return a per-thread status in LockCookie.
	  Also added support for recursive writer-lock requests.

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

	* ThreadAbortException.cs: use same HResult as MS.
	* Timer.cs: abort the running thread when disposing the Timer. This
	fixes NullRefs when finishing xsp.

	([email protected]). Fix finalization problems during appdomain unload.

2004-02-23  Jackson Harper <[email protected]>

	* LockCookie.cs: Add some fields for restoring locks.
	* ReaderWriterLock.cs: Implement
	* LockQueue.cs: New File - used for queueing thread locks in
	ReaderWriterLock.
	
2004-02-19  Jackson Harper <[email protected]>

	* Monitor.cs: Fix spelleng.
	
2004-02-09  Zoltan Varga  <[email protected]>

	* Thread.cs: Add fields added to unmanaged MonoThread here as well.
	Fixes random errors caused by memory corruption.

2004-02-06  Zoltan Varga  <[email protected]>

	* Thread.cs: Store the thread name in unmanaged memory, since the
	thread object is shared between appdomains.

2004-02-05  Sebastien Pouliot  <[email protected]>

	* Thread.cs: Implemented CurrentPrincipal.

2004-01-22  Gonzalo Paniagua Javier <[email protected]>

	* Thread.cs: delayed thread creation until Start is called. If we

	step towards fixing bug #53078. 

2003-12-02  Dick Porter  <[email protected]>

	  methods. They are used in CrossAppDomainChannel to save and restore
	  thread's local data when switching between domains.

2003-10-08  Gonzalo Paniagua Javier <[email protected]>

	* ManualResetEvent.cs: added check for disposed.
	* Thread.cs: no need to init this field.

2003-10-01  Zoltan Varga  <[email protected]>

	* Thread.cs: Add locking to AllocateNamedDataSlot and 
	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]>

	* Thread.cs: SetData() method: use Hashtable.Contains to check
	  if a dataslot has been allocated (value could be null).

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

	* WaitHandle.cs (CheckDisposed): This method is not in the public
	API, mark it as 'internal'.

2003-07-01  Dick Porter  <[email protected]>

	* Thread.cs: Throw an exception if thread creation failed.
	(Better than just blowing up later.)

2003-06-27  Dietmar Maurer  <[email protected]>

	* ThreadPool.cs: use async delegate invoke.

2003-06-25  Dick Porter  <[email protected]>

	* WaitHandle.cs: Default handle value should be InvalidHandle, not
	Zero.

2003-06-21  Gonzalo Paniagua Javier <[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]>

	* NativeEventCalls.cs: added CloseEvent_intenal.
	* 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]>

	* Monitor.cs: removed test_owner, the check is already done in the
	icall.

Tue May 13 15:34:29 CEST 2003 Paolo Molaro <[email protected]>

	a new field to support thread-static data.

2003-04-17  Pedro Mart�ez Juli� <[email protected]>

	* Timer.cs: Change the position of two lines because they were
	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.

2003-03-25  Zoltan Varga  <[email protected]>

	* Thread.cs: Fix visibility of ResetAbort().

	* Thread.cs: Changed implementation of CurrentContext, adapted to the changes
	  in the runtime.

	* Thread.cs: implemented CurrentContext.

2003-02-17  Gonzalo Paniagua Javier <[email protected]>

	* Thread.cs: made the thread_id for the current thread accesible through
	an internal property.  

2003-02-17  Dick Porter  <[email protected]>

	* Thread.cs: Added the Start semaphore field to the class.  Update
	the thread state after Start() has returned, not before.

2003-02-13  Zoltan Varga  <[email protected]>

	* Thread.cs (Sleep): Timeout.Infinite is a value argument.

2003-02-11  Dick Porter  <[email protected]>

	* ThreadPool.cs: Temporary removed the usage of monitor thread, implemented a 
                    model more equal to the MS one.

	* Monitor.cs:
	* Thread.cs:
	* ThreadPool.cs:
	* Timer.cs:
	* WaitHandle.cs: Use TotalMilliseconds to convert a TimeSpan to
	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]>

	* ThreadPool.cs: set IsThreadPoolThread before starting the worker.

2002-09-11  Dick Porter  <[email protected]>

	* WaitHandle.cs: Implemented WaitAll(), WaitAny() and WaitOne() as
	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.
