2009-11-02  Sebastien Pouliot  <sebastien@ximian.com>

        * Thread.cs (set_CurrentUICulture): Delay setting in_currentculture
        to true until after the null check and the return statement.

2009-10-21  Sebastien Pouliot  <sebastien@ximian.com>

        * WaitHandle.cs: Add missing validations for 'millisecondsTimeout'
        in Wait[One|Any|All]. Also call the overloaded (bool) methods for
        WaitAll to reduce code duplication.

2009-10-20  Sebastien Pouliot  <sebastien@ximian.com>

        * Timer.cs: Always call Init from every constructors to avoid 
        duplicate checks. Fix validations on different dueTime and period
        (ctor and Change methods). Seal private TimerComparer class and
        avoid multiple (identical) casts in its Compare method. Seal 
        private Scheduler class.

2009-10-20 Gonzalo Paniagua Javier <gonzalo@novell.com>

        * Timer.cs: make sure we don't insert 2 timers with the same key.

2009-10-20  Jb Evain  <jbevain@novell.com>

        * Thread.cs: change type of the current_appcontext field to object
        to avoid triggering static constructors unless explicitely required.

2009-10-16 Gonzalo Paniagua Javier <gonzalo@novell.com>

        * Timer.cs: looks like any negative value is treated as Infinite.

2009-10-07  Sebastien Pouliot  <sebastien@ximian.com>

        * Thread.cs: Remove LocalDataStoreSlot-related methods from
        Moonlight build

        * Thread.cs: StartSafe: ignore ThreadAbortExceptions.

2009-09-27 Gonzalo Paniagua Javier <gonzalo@novell.com>

        * Timer.cs: account for the time spent sending jobs to the queue.

2009-09-26  Mark Probst  <mark.probst@gmail.com>

        * Thread.cs: Serialize the principal so as not to make it cross
        appdomains.  Two new internal calls for copying byte arrays
        between domains.

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

        * Thread.cs: 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.

        * Environment.cs: Corlib version bump.

2009-09-24 Gonzalo Paniagua Javier <gonzalo@novell.com>

        * Timer.cs: no need to wake up the scheduler when removing the next
        scheduled item.

2009-09-23 Gonzalo Paniagua Javier <gonzalo@novell.com>

        * Timer.cs: rewritten. It only has one queue now and it is sorted by
        due time. Before this changes, it was using a lot of CPU when there
        were a lot of 'future' timers.

2009-09-23  Sebastien Pouliot  <sebastien@ximian.com>

        * ExecutionContext.cs: Don't use SecurityContext and don't expose
        AsyncFlowControl for NET_2_1
        * ThreadAbortException.cs: Remove ExceptionState from NET_2_1
        * Thread.cs: Don't expose ApartmentState and remove Suspend and
        Resume methods for NET_2_1
        * ThreadPool.cs: Remove GetAvailableThreads and Unsafe* methods
        for NET_2_1

2009-09-22  Jb Evain  <jbevain@novell.com>

        * Timer.cs: MONOTOUCH doesn't support remoting, so do not pass
        true to exitContext when calling WaitOne on a WaitHandle.

2009-09-22  Sebastien Pouliot  <sebastien@ximian.com>

        * Thread.cs: Remove [Get|Set]CompressedStack for NET_2_1

2009-09-21  Sebastien Pouliot  <sebastien@ximian.com>

        * Thread.cs: Remove CurrentPrincipal property for NET_2_1
        * ExecutionContext.cs: Remove Run method for NET_2_1

2009-08-19  Jérémie Laval  <jeremie.laval@gmail.com>

        * ParallelLoopState.cs: Take in account that
        AtomicBoolean is a class.

2009-08-19  Jérémie Laval  <jeremie.laval@gmail.com>

        * AtomicBoolean.cs: Turn it into a class
        * CountdownEvent.cs: Work on cached variable. Make sure
        count doesn't go under 0.

2009-08-11  Jérémie Laval  <jeremie.laval@gmail.com>

        * Watch.cs:

2009-08-11  Jérémie Laval  <jeremie.laval@gmail.com>

        * Parallel.cs: Disable While method.
        * CountdownEvent.cs: Fix method signature.
        * Barrier.cs: Moved type.
        * AggregateException.cs: Moved type.

2009-08-04 Jérémie Laval  <jeremie.laval@gmail.com>

        * SpinLock: Remove unused private methods.

2009-08-03  Zoltan Varga  <vargaz@gmail.com>

        * Thread.cs: Always call Thread_free_internal from the finalizer, since
        it frees other things besides the handle. Fixes #527576.

2009-07-31  Jérémie Laval  <jeremie.laval@gmail.com>

        * Snzi.cs:
        * Parallel.cs:

2009-07-30 Jérémie Laval  <jeremie.laval@gmail.com>

        * AggregateException.cs:
        * AtomicBoolean.cs:

        * Watch.cs: Add ParallelFx files for System.Threading namespace

2009-07-21  Jb Evain  <jbevain@novell.com>

        * ThreadPool.cs: avoid an unecessary method call when not running
        in moonlight.

2009-07-20  Jb Evain  <jbevain@novell.com>

        * Thread.cs: use the moonlight specific thread start
        hack for the net_2_1 profile exclusively.

2009-06-25  Miguel de Icaza  <miguel@novell.com>

        * Timer.cs: Throw ArgumentNullException if the callback is null. 

2009-06-22  Bill Holmes  <billholmes54@gmail.com>

        * Thread.cs : Adding interrupt_on_stop field.

        Contributed under MIT/X11 license.

2009-06-10  Rolf Bjarne Kvinge  <RKvinge@novell.com>

        * Thread.cs: MoonlightUnhandledException: ensure there's no way to
        reach native code with a managed exception.

2009-06-10  Sebastien Pouliot  <sebastien@ximian.com>

        * Thread.cs: Refactor calling Moonlight's OnUnhandledException to 
        make sur the delegate it not called from a [SecuritySafeCritical]
        caller.
        * ThreadPool.cs: Reuse the above code for QueueUserWorkItem. 
        Original patch from Alan McGovern

2009-06-10  Marek Safar  <marek.safar@gmail.com>

        * LockRecursionException.cs: New file.

2009-04-21  Mark Probst  <mark.probst@gmail.com>

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

2009-04-20  Rolf Bjarne Kvinge  <RKvinge@novell.com>

        * 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  <mark.probst@gmail.com>

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

2009-04-18  Mark Probst  <mark.probst@gmail.com>

        * 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 <gonzalo@novell.com>

        * WaitHandle.cs: implemented 2 missing WaitAny overloads.

2009-03-05 Rolf Bjarne Kvinge  <RKvinge@novell.com>

        * WaitHandle.cs: Added missing WaitOne overload.

2009-02-20 Gonzalo Paniagua Javier <gonzalo@novell.com>

        * WaitHandle.cs: implemented SignalAndWait.

2009-02-18  Jb Evain  <jbevain@novell.com>

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

2009-01-30  Andreia Gaita  <avidigal@novell.com>

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

2008-12-20  Miguel de Icaza  <miguel@novell.com>

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

2008-11-25  Geoff Norton  <gnorton@novell.com>

        * 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 <gonzalo@novell.com>

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

2008-09-19  Miguel de Icaza  <miguel@novell.com>

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

Tue Sep 16 21:02:59 CEST 2008 Paolo Molaro <lupus@ximian.com>

        * Thread.cs: fixed SpinWait() implementation (bug #423582).

Tue Sep 9 15:19:48 CEST 2008 Paolo Molaro <lupus@ximian.com>

        * 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.

2008-07-03  Andreas Nahr  <ClassDevelopment@A-SoftTech.com>

        * ThreadPool.cs:
        * LockCookie.cs:
        * Interlocked.cs:
        * ExecutionContext.cs:
        * AsyncFlowControl.cs:
        * AbandonedMutexException.cs: Fix parameter names

2008-07-02  Zoltan Varga  <vargaz@gmail.com>

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

2008-06-18  Kornél Pál  <kornelpal@gmail.com>

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

2008-06-14  Zoltan Varga  <vargaz@gmail.com>

        * Thread.cs: Sync layout with unmanaged side.

2008-06-07  Zoltan Varga  <vargaz@gmail.com>

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

2008-04-11  Zoltan Varga  <vargaz@gmail.com>

        * Thread.cs: Make in_currentculture non-static. Fixes #378892.

2008-04-07  Dick Porter  <dick@ximian.com>

        * Thread.cs: Fix throwing of exceptions when manipulating
        ApartmentState.  Fixes part of bug 324338.

2008-04-01: Eyal Alaluf <eyala@mainsoft.com>

        * Thread.cs: Put a NumberFormatter instance as a member of the current
          thread so it can reused for performint ToString conversions.

2008-03-26  Massimiliano Mantione <massi@ximian.com>
        * 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 <lupus@ximian.com>

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

Fri Feb 22 11:23:53 CET 2008 Paolo Molaro <lupus@ximian.com>

        * Thread.cs: implemented Begin/EndCriticalRegion.

2008-02-03  Sebastien Pouliot  <sebastien@ximian.com>

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

2008-01-06  Zoltan Varga  <vargaz@gmail.com>

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

2008-01-03  Zoltan Varga  <vargaz@gmail.com>

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

2007-12-27  Zoltan Varga  <vargaz@gmail.com>

        * Thread.cs: Change the type of synch_cs to an IntPtr to be in synch with the
        unmanaged definition.

2007-11-20  Atsushi Enomoto  <atsushi@ximian.com>

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

2007-11-20  Atsushi Enomoto  <atsushi@ximian.com>

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

Thu Nov 8 18:36:25 CET 2007 Paolo Molaro <lupus@ximian.com>

        * 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  <dick@ximian.com>

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

2007-10-24  Dick Porter  <dick@ximian.com>

        * 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  <atsushi@ximian.com>

        * SynchronizationContext.cs : removed SendOrPost().

Wed Oct 17 13:24:33 CEST 2007 Paolo Molaro <lupus@ximian.com>

        * Timer.cs: better cleanup test for the expired array.

Tue Oct 16 17:22:15 CEST 2007 Paolo Molaro <lupus@ximian.com>

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

Tue Oct 16 12:14:43 CEST 2007 Paolo Molaro <lupus@ximian.com>

        * 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  <dick@ximian.com>

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

2007-09-25  Dick Porter  <dick@ximian.com>

        * Thread.cs: Keep ManagedThreadId constant over the lifetime of a
        Thread.  Patch from jlarimer@gmail.com fixing bugs 325367 and
        325566.

2007-09-25  Jonathan Pobst  <monkey@jpobst.com>

        * SynchronizationContext.cs: Implement SetSynchronizationContext.

2007-09-06  Dick Porter  <dick@ximian.com>

        * 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  <drieseng@users.sourceforge.net>

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

2007-08-08  Zoltan Varga  <vargaz@gmail.com>

        * Thread.cs: Add a fixme.

2007-07-21  Miguel de Icaza  <miguel@novell.com>

        * 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.

        * 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.

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

2006-02-09  Miguel de Icaza  <miguel@novell.com>

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

2005-05-20  Sebastien Pouliot  <sebastien@ximian.com>

        * AsyncFlowControl.cs: Now available, as internal, in NET_1_1. This is
        required to get some methods from SecurityContext and ExecutionContext
        working.
        * CompressedStack.cs: Now includes the current CompressedStack in a new
        Capture.
        * ExecutionContext.cs: Includes more methods in NET_1_1 to enable 
        ThreadPool.UnsafeQueueUserWorkItem to work properly (i.e. without

        * 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

        * 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  <sebastien@ximian.com> 

        * 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 <gonzalo@ximian.com>

        * ReaderWriterLock.cs: fix random ApplicationException errors. Tested

        before NET_2_0.

2005-04-28  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * AsyncFlowControl.cs: Updated wrt beta2.
        * ExecutionContext.cs: Updated wrt beta2. Class is now internal in 
        NET_1_1 to allow the compressed stack propagation to other threads.
        * CompressedStack.cs: Updated wrt beta2. Class is internal in NET_1_1 
        to allow the compressed stack propagation to other threads.

        wide) mutexes.
        * Thread.cs: Added LinkDemand for ECMA public key on [Get|Set]
        CompressedStack methods.
        * WaitHandle.cs: Added LinkDemand and InheritanceDemand for

2004-06-11  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * Thread.cs:
        (CurrentPrincipal): lock on CurrentThread, not typeof (Thread) and set
        the thread IPrincipal if we get it from the AppDomain.

2004-06-09  Gert Driesen <drieseng@users.sourceforge.net>

        * CompressedStack.cs: Added finalizer to match public API of
        MS.NET

2004-05-19  Lluis Sanchez Gual <lluis@ximian.com>

        * Thread.cs: Some fixes in Abort. Implemented Suspend and Resume.
          Added internal interruption_requested field.

2004-05-13  Sebastien Pouliot  <sebastien@ximian.com>

        * 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  <vargaz@freemail.hu>

        * CompressedStack.cs: New file.

2004-04-15  Lluis Sanchez Gual <lluis@ximian.com>

        * 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 <lluis@ximian.com>

        * 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 <lluis@ximian.com>

        * 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  <vargaz@freemail.hu>

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

2004-04-08  Jackson Harper  <jackson@ximian.com>

        * ReaderWriterLock.cs: Fix tyop
        
2004-04-08  Lluis Sanchez Gual <lluis@ximian.com>

        * 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 <gonzalo@ximian.com>

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

2004-04-07  Jackson Harper  <jackson@ximian.com>

        * Thread.cs: Use new culture info method for constructing the
        current culture.
        
2004-04-07  Lluis Sanchez Gual <lluis@ximian.com>

        * 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 <lluis@ximian.com>

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

2004-04-06  Lluis Sanchez Gual <lluis@ximian.com>

        * 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 <gonzalo@ximian.com>

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

2004-03-15  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * NativeOverlapped.cs: added 2 new internal fields.
        * Overlapped.cs: implemented, but it's not used.

        * ThreadPool.cs: implemented BindHandle.

2004-03-08  Zoltan Varga  <vargaz@freemail.hu>

        * Timer.cs (Dispose): Applied patch from Jaroslaw Kowalski 
        (jaak@zd.com.pl). Fix finalization problems during appdomain unload.

2004-02-23  Jackson Harper <jackson@ximian.com>

        * 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 <jackson@ximian.com>

        * Monitor.cs: Fix spelleng.
        
2004-02-09  Zoltan Varga  <vargaz@freemail.hu>

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

2004-02-06  Zoltan Varga  <vargaz@freemail.hu>

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

2004-02-05  Sebastien Pouliot  <sebastien@ximian.com>

        * Thread.cs: Implemented CurrentPrincipal.

2004-01-22  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * Thread.cs: delayed thread creation until Start is called. If we
        don't do that and Start() is not called, the thread is leaked. First
        step towards fixing bug #53078. 

2003-12-02  Dick Porter  <dick@ximian.com>

        * Thread.cs: Throw InvalidOperationException if Thread.Name is
        already set.

2003-12-01  Dick Porter  <dick@ximian.com>

        * Thread.cs: Implement CurrentCulture and CurrentUICulture

2003-11-12  Miguel de Icaza  <miguel@ximian.com>

        * Thread.cs: Add new VolatileRead/VolatileWrite methods from 1.1

2003-10-23  Lluis Sanchez Gual  <lluis@ximian.com>

        * Thread.cs: Added ResetDataStoreStatus and RestoreDataStoreStatus
          methods. They are used in CrossAppDomainChannel to save and restore
          thread's local data when switching between domains.

2003-10-08  Gonzalo Paniagua Javier <gonzalo@ximian.com>

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

2003-10-01  Zoltan Varga  <vargaz@freemail.hu>

        * Thread.cs: Add locking to AllocateNamedDataSlot and 
        FreeNamedDataSlot.

Wed Aug 20 12:01:36 CEST 2003 Paolo Molaro <lupus@ximian.com>

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

2003-08-14  Lluis Sanchez Gual  <lluis@ximian.com>

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

2003-07-23  Duncan Mak  <duncan@ximian.com>

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

2003-07-01  Dick Porter  <dick@ximian.com>

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

2003-06-27  Dietmar Maurer  <dietmar@ximian.com>

        * ThreadPool.cs: use async delegate invoke.

2003-06-25  Dick Porter  <dick@ximian.com>

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

2003-06-21  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * ThreadPool.cs: correctly create a TimeSpan with provided the number of
        milliseconds.

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

2003-06-06  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * WaitHandle.cs: checks and exceptions.

2003-06-02  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * NativeEventCalls.cs: added CloseEvent_intenal.
        * WaitHandle.cs: call CloseEvent_internal when disposing.

2003-05-31  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <lupus@ximian.com>

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

Tue May 13 15:34:29 CEST 2003 Paolo Molaro <lupus@ximian.com>

        * Thread.cs: added missing field used by the runtime and
        a new field to support thread-static data.

2003-04-17  Pedro Mart?ez Juli? <yoros@wanadoo.es>

        * 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  <dick@ximian.com>

        * 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  <miguel@ximian.com>

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

2003-03-25  Zoltan Varga  <vargaz@freemail.hu>

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

2003-03-18  Dick Porter  <dick@ximian.com>

        * Thread.cs: Keep the thread state updated in all the places that
        require it.  (Suspend, Resume and Interrupt not handled yet)

2003-03-03  Lluis Sanchez Gual <lluis@ideary.com>

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

2003-02-19  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * Thread.cs: implemented CurrentContext.

2003-02-17  Gonzalo Paniagua Javier <gonzalo@ximian.com>

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

2003-02-17  Dick Porter  <dick@ximian.com>

        * 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  <vargaz@freemail.hu>

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

2003-02-11  Dick Porter  <dick@ximian.com>

        * Monitor.cs: Infinite wait is Infinite, not 0 ms

2003-02-10  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * Thread.cs: fixed bug #37759.

2003-02-07  Patrik Torstensson

        * Timer.cs: Set the Background thread flag for the timer thread

2003-02-05  Patrik Torstensson

        * ThreadPool.cs: Reformated and fixed issue that made all thread exit the pool. 

2003-02-04  Lluis Sanchez Gual <lluis@ideary.com>

        * ThreadPool.cs: Implemented RegisterWaitForSingleObject methods.

Tue Jan 28 17:55:59 CET 2003 Paolo Molaro <lupus@ximian.com>

        * Thread.cs: delay-init datastorehash.

2003-01-10  Patrik Torstensson  <totte@race-x-change.com>

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

2002-12-10  Dick Porter  <dick@ximian.com>

        * 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  <martin@ximian.com>

        * 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 <gonzalo@ximian.com>

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

2002-10-25  Zoltan Varga  <vargaz@freemail.hu>

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

2002-10-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <gonzalo@ximian.com>

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

2002-09-11  Dick Porter  <dick@ximian.com>

        * Mutex.cs: 
        * ManualResetEvent.cs:

        before adding a new one.

        Use the Thread object destructor to tell the runtime to close the
        thread handle.

2002-04-14 Patrik Torstensson <patrik.torstensson@labs2.com>

        * Interlocked.cs: made all methods icalls.

2002-04-14  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * IOCompletionCallback.cs: added attributes to the delegate
        (CLSCompliant(false) and Serializable).

2002-04-14 Patrik Torstensson <patrik.torstensson@labs2.com>
        * Thread.cs: Fixed IsThreadPoolThread to use a internal property instead of extending 
                                 the threadstate enum.
        * ThreadPool.cs: Now using the internal Isthreadpoolthread property
        * ThreadState.cs: removed non-standard enum (ThreadPoolThread)

2002-04-14 Patrik Torstensson <patrik.torstensson@labs2.com>

        * ThreadState.cs: Added enum for threadpool thread
        * Thread.cs: changed the set/clr_state to be internal (used from threadpool)
        * Thread.cs: Added IsThreadPoolThread
        * ThreadPool.cs: Implementation of QueueUserWorkItem

                     and the ReleaseMutex)

2002-01-15  Dick Porter  <dick@ximian.com>

        * WaitHandle.cs:

        with the class library's

2002-01-10  Dick Porter  <dick@ximian.com>

        * WaitHandle.cs: Added checks for too many handles and null
        handles in WaitAll() and WaitAny
        

2002-01-05  Ravi Pratap  <ravi@ximian.com>

        * AutoResetEvent.cs, ManualResetEvent.cs, Monitor.cs : MonoTODO

        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
