4.92.00 April 2 2016

Important notes (changes that may break existing code)
======================================================
* Changed TkbmMWAfterMessageProcessedEvent by adding argument
var AAction:TkbmMWMessageProcessingSuccessAction

New stuff
=========
- Added AWaitUntilConnected (default false) and
AWaitUntilDisconnected (default false) to TkbmMWAMQPClient Connect/
and Disconnect methods.
- Generally slightly improved C++ support.
- Added new TkbmMWDependency class for guaranteeing initialization and
finalization order of units. Units depended on are initialized first
and finalized later. Modified all kbmMW code to use dependency
class.
- Added new TkbmMWDebugMemory class for keeping track of memory
allocations and leak detection. Enterprise Edition only.
Include kbmMWDebugMemory as early as possible in your uses clause
(but after FastMM if you are specifying that).
See demo project (debugmemory) for usage.
- Added compact stack version of TkbmMDebugStackTrace not requiring
addition memory allocations while running.
- Added support for global function in TkbmMWScheduler.Schedule.
- Added PrevRunStamp in TkbmMWScheduledEvent.
- Added TkbmMWInterlocked.Increment/Decrement for uint64.
- Added TkbmMWLockFreeHashArray<T> where a custom value type can be
used. key is still cardinal/uint64.
- Added TkbmMWLockFreeHashArray64 (64 bit data value).
- Added ResetEnum, Enum, Capacity, Count, AssignValue to all
TkbmMWLockFreeHashArray implementations.
- Added optional argument ACount:integer=0 to
TkbmMWCustomThreadPool.PreAllocate.
Can ask for preallocation of ACount instances (will be limited by
max count defined for thread pool).
- Added new TkbmMWLog data type: mwldtAllocation. It will be used by
memory leak detection for reporting allocation leaks.
- Added mwldtAllocation to TkbmMWLogDataType. Its used for filtering
out memory allocation logs.
- Added support for specifying max file size (in kB) for log and
audit files in IkbmMWLocalFileLogManager. Default 1024 for log
files and no max for audit.
If file size is exceeded current file is renamed to .bak
and a new file created. Only one backup file can currently exist.
- Added support in IkbmMWTeeLogManager for AddLogManager and
RemoveLogManagers.
Allows for dynamically add and remove logmanagers to the tee log
manager.
Currently max 10 concurrent logmanagers are supported to be
referenced by a tee log manager.
Added overloaded constructors for referencing 0 to 4 exisitng log
manager instances when creating a tee logmanager instance.
- Added Tag:integer and Data:variant properties to
IkbmMWScheduledEvent.
Allows for tagging custom data to a scheduled event.
Matching methods WithTag(..) and WithData(..) added for fluently
typing.
- Added PrevRunStamp:int64 property to IkbmMWScheduledEvent for
obtaining info for when last run happened.
- Added Schedule(AGlobalFunction:TkbmMWOnScheduledFunction) to
TkbmMWScheduler.
- Added ASpaceAsPlus:boolean (default true) to kbmMWEncodeEscapes
method in kbmMWHTMLUtils.pas. If set to false, will not replace
space with +.
- Added delayed commit to TkbmMWCustomSAFServerTransport.
This is to fix that message pops should not be committed until
message has truely been processed. This especially relates to
request that are looped thru the TkbmMWServer application server
functionality. Earlier it was possible that messages were put into
a holding pattern in the TkbmMWServer (while waiting to be
processed) but thus have been popped off the inbound queue and
committed and thus removed from it, before the application server
actually had processed or failed processing the message.
- Added server queue congestrion support on
TkbmMWCustomSAFServerTransport.
This ensures that request/service call messages will not overwhelm
the server queue. Default is
mwmqoFailOnCongestion,mwmqoDeleteInvalidMessage
and max CPUCount*10 messages in queue. Default component name for
the server queue is transport name+'_'+KBMMW_DEFAULT_SERVER_QUEUE.
If congestion happens, the push on the server queue fails and
message will automatically be rolledback on the source queue
(typically the inbound queue) to ensure no messages are lost.
- Added TkbmMWDebugStack.StackTraceAsString function to easily
convert collected stack to printable string.
- Added more features for obtaining a stacktrace.
- Added TkbmMWInterlocked.Increment2,Decrement2,Exchange2,
Add2,CompareAndExchange2 supporting TkbmNativeUInt.
- Added TkbmMWInterlocked.Increment,Decrement supporting uint64.
- Added TkbmMWLockFreeHashArray2<T> to kbmMWGlobal, which takes
2 TkbmNativeUInt keys to reference data of type <T>.
- Added TkbmMWDynamicLockFreeHashArray<T> descending from
TkbmMWLockFreeHashArray<T>. It auto resizes to 150%
when its getting to more than 60% of capacity.
- Added TkbmMWLockFreeHashArrayNative descending from
TkbmMWLockFreeHashArray2 referencing TkbmNativeUInt.
- Performance optimized kbmMWGetCurrentThreadID for x86 and x64.
- Added procedures LockedFreeNotification(AComponent: TComponent) and
procedure LockedRemoveFreeNotification(AComponent: TComponent)
to TkbmMWCustomConnectionPool. Use these instead of FreeNotification
and RemoveFreeNotification to ensure threadsafety.
- Added AddBatchedMessage method to IkbmMWCustomTransportStream.
- Added DelayedCommitOwner property to IkbmMWCustomTransportStream.
This can be used to identify the original source (holding) queue
for the message.
- Added mwmqoFailOnCongestion to TkbmMWMessageQueueOption.
If a queue is getting congested this will lead to push returning
false, and message not being pushed on queue.
- Added IkbmMWMessageQueueCustomAction and descendants
IkbmMWMessageQueuePushAction,
IkbmMWMessageQueueTentativelyPopAction,
IkbmMWMessageQueueCommitAction, IkbmMWMessageQueueRollbackAction,
IkbmMWMessageQueueDeleteAction, IkbmMWMessageQueueRejectAction,
IkbmMWMessageQueueStalledAction, IkbmMWMessageQueueCongestionAction,
IkbmMWMessageQueueClearAction,
IkbmMWMessageQueueTentativelyPushAction,
IkbmMWMessageQueueCommitPushAction,
IkbmMWMessageQueueRollbackPushAction
Allows for any class to subscribe for various events on a
message queue.
- Added events OnPush,OnTentativelyPop,OnCommit,OnRollback,OnDelete,
OnReject,OnStalled,OnCongestion,OnClear,OnTentativelyPush,
OnCommitPush,OnRollbackPush to TkbmMWCustomMessageQueueAction.
- Added mwpsaRetry to TkbmMWMessageProcessingSuccessAction.
Controls if a failed message processing operation should be retried.

Changes/minor additions
=======================
- Changed TkbmMWScheduler to preallocate at least 1 relaxed thread if
any relaxed events have been defined, even if they are not to run
yet. Purpose is to play nice with memory leak detection.
- Changed TkbmMWLockFreeHashArray to inherit from generic version,
and be named TkbmMWLockFreeHashArray32.
- Changed TkbmMWCustomTransportStream to allow for BatchedMessages=nil
to improve performance and memory usage.
- Added check for out of memory conditions in TkbmMWBufferPages.
- Added missing Occurs(const AOccurance:TkbmMWScheduleOccurance)
method to IkbmMWScheduledEvent to be able to type fluently.
- Changed KBMMW_THREAD_TIMEOUT_GRANULARITY to 50ms instead
of 2000ms to ensure more smooth shutdown of threads.
- Changed so TkbmMWThreadEntry.Create do not autostart inner thread.
- Changed TkbmMWCustomThreadPool.Create to allow for specifying if to
autostart threads created via pool.
- Changed TkbmMWCustomThreadPool.PreAllocate to take optional
arguments setting pool size and autostart option.
- Improved early error detection in ReadSubjectHeader.
- Changed TkbmMWAfterMessageProcessedEvent by adding argument
var AAction:TkbmMWMessageProcessingSuccessAction
- Changed TkbmMWCustomGroupedMultithreadMessageQueueProcessor by
adding setters to numerous properties.
- Changed TkbmMWMemoryQueue options to default not batch any messages.
- Changed TkbmMWGroupedMessageQueueProcessorThread to default
congest at 10 messages for normal priority messages.
The default congestion treshold will be overwritten with QueueSize
setting when the processor is started.
- Improved Firemonkey support for TkbmMWJPEG.

Fixes
=====
- Fixed problems with TkbmMWDateTime due to threadsafety issues in
Embarcadero's TTimeZone.Local implementation, which could lead to
various exceptions on some OS versions.
- Fixed issue with SendPing resulting in index out of range due to
missing unstreaming of request values.
- Fixed multithreaded race condition on unhooking components from
connectionpool.
- Fixed bug where not all properties of a scheduled event was
considered.
- Fixed bug in TkbmMWScheduledEvents where precise event thread was
not guaranteed started immediately.
- Fixed shutdown problem in Indy 10 due to TerminateYarn bug.
- Fixed potential race condition bug in TkbmMWFilePool.
- Fixed bug in TkbmMWMREWLock and performance optimized it. Added a
number of introspecting functions:
ReadLockedBy, WriteLockedBy, LockedByAsString,
WriteLockRecursiveCount, ReaderLockCount which can be used to query
current status of a lock.
Now kbmMW default uses TkbmMWMREWLock for all locking.
This can be disabled by commenting
{$IFDEF KBMMW_SUPPORT_FASTMRWSLOCK}
in kbmMWConfig.inc.
- Fixed memory leak in TkbmMWHashBuckets.
- Fixed TkbmMWMemoryStream.Read when attempting to read 0 bytes.
- Fixed bugs in TkbmMWCustomThread.Stop.
- Fixed TkbmMWCipherCustomDES, TkbmMWCipherRijndael (AES) and
TkbmMWCipherIDEA on 64 bit platforms.
- Fixed TkbmMWCustomClient.SendPing without arguments not correctly
sending NULL.
- Fixed ftDateTime bug in UniDAC adapter.
