PageSubscriptionImpl::ackTx is already performing a counter update
using the message persistent size: the size can be reused on
PagePosition::setPersistentSize, avoiding to query the page cache just
to compute it.
These improvements were also part of this task:
- Routing is now cached as much as possible.
- A new Runnable is avoided for each individual message,
since we use the Netty executor to perform delivery
https://issues.apache.org/jira/browse/ARTEMIS-2205
TransactionImpl::properties are often not used and could be
avoided to be allocated.
OperationContextImpl.TaskHolders instances are turned into static
classes to avoid refecencing back the context, making the life
easier for the GC.
OperationContexImpl volatile loads can be reduced to make the
code faster on the hot path.
When a receiving transaction is committed in a paging situation,
if a page happens to be completed and it will be deleted in a
transaction operation (PageCursorTx). The other tx operation
RefsOperation needs to access the page (in PageCache) to finish
its job. There is a chance that the PageCursorTx removes the
page before RefsOperation and it will cause the RefsOperation
failed to find a message in a page.
When a node tries to reconnects to another node in a scale down cluster,
the reconnect request gets denied by the other node and keeps retrying,
which causes tasks in the ordered executor accumulate and eventually OOM.
The fix is to change the ActiveMQPacketHandler#handleCheckForFailover
to allow reconnect if the scale down node is the node itself.
Not closing the InputStream makes this test flaky on Windows. The test
breaks because FileMoveManager::delete(java.io.File) Line 221 fails
to delete the file if it's still "owned" by the JVM process on Windows.
With AMQP protocol when some messages are received in a transaction,
calling JMX QueueControl.listDeliveringMessages() returns empty list
before the transaction is committed.
Add test cases
Add GroupSequence to Message Interface
Implement Support closing/reset group in queue impl
Update Documentation (copy from activemq5)
Change/Fix OpenWireMessageConverter to use default of 0 if not set, for OpenWire as per documentation http://activemq.apache.org/activemq-message-properties.html
Implement custom LVQ Key and Non-Destructive in broker - protocol agnostic
Make feature configurable via broker.xml, core apis and activemqservercontrol
Add last-value-key test cases
Add non-destructive with lvq test cases
Add non-destructive with expiry-delay test cases
Update documents
Add new methods to support create, update with new attributes
Refactor to pass through queue-attributes in client side methods to reduce further method changes for adding new attributes in future and avoid methods with endless parameters. (note: in future this should prob be done server side too)
Update existing test cases and fake impls for new methods/attributes
