Switching addMessageLast to tryAddMessageLast when messages are added
to a Queue pending cursor to allow a potential deadlock to be
avoided. There is more work to be done here but this will at least
prevent a deadlock from occurring.
Fix and test based off of a patch created by Timothy Bish.
Adding support for consumers on virtual destinations to create network
demand. This behavior is turned off by default but can be enabled.
For example, if a consumer comes online for a queue that is part of a
VirtualTopic, this will cause a network of brokers to forward messages
because a demand subscription will be created. Same for if a consumer
comes online for a forwarded destination from a composite
destination.
There is also an option to enable flow based on the existence of a
virtual destination if the virtual destination is forwarding to a
Queue.
Full configuration instructions for this feature will be on the wiki page.
Improving the warning message for a percent disk usage check so it is
more clear what the original limit was set to and what the current
limit is being set to.
When possible check for noLocl changes on durable subscription
reactivation and recreate the durable sub if it changes. For both
selector change and noLocal change also update the AbstractSubscription
selectorExpression so it matches with what was requested.
Adding metrics to track the pending message size for a queue and for
subscribers. This is useful so that not only the pending count is
known but also the total message size left to consume. Also improving
the message size store tests as well.
-Cleaned up missing license headers and refactored packages.
-Added configuration options for a protocol detection timeout and
for the max number of connections accepted at the same time.
-Fixed a regression with connection counts
-Also added some more tests
Adding support for auto detection of wire protocols over a transport.
OpenWire, AMQP, STOMP, and MQTT can all be detected and the broker
will properly handle each one over a given Transport. Currently
auto TCP, NIO, SSL, and NIO+SSL transports can handle auto-detection
of the wire format and client but support could be added in the
future for other transports like websockets.
Updating MemoryTopicMessageStore to decrement store statistics on cache
eviction. Updating KahaDBMessageStoreSizeStatTest to account for the
fact that a LRU cache is used so the last 100 messages are kept in
memroy.
Switching to a List to track dispatched messages in a TopicSubscription
to be consistent with a PrefetchSubscription and to prevent an error
in case acks come back out of order.
Apply patch from Ganesh Murthy to resolve issue of creation of durable
subscriber fails via broker AdminView due to lack of SecurityContext on
ConnectionContext
Reworking DurableConduitBridge to look up subscriptions from the
TopicRegion instead of the RegionBroker since inactive subscriptions
need to be looked at as well when dynamicOnly is false for a
network bridge.
