Reverting commit because allowing 0 doesn't actually set the usage to
0 size. It ends up disabling the check all together which was the
opposite intention of the commit.
This reverts commit 3b658f8e1a.
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.
resolves#123
This commit resolves an issue where unmatched acknowledgement
messages could be received when running a MDB consumer and
sending messages with a short TTL. The expiration logic when
receiveing an expired Message Ack will now only expire messages
in dispatch relating to the received ack, not all expired messages
in the dispatch list.
Use the latest openwire version marshallers in the KahaDB store when
starting from a clean install, drop back to the version used in the
existing store if one is found.
This commit adds an Inflight message size statistic to SubscriptionStatistics
so we can know the size of all the messages that are inflight, besides just the count.
Added a getMessageSize method to MessageStore to support retrieving the
total message size of all stored messages for a destination. Added a
new storeMessageSize statistic to DestinationStatistics.
Remove of a durable subscription when the keepDurableSubActive flag is
true (default) did not actually stop and cleanup the still active cursor
due to the fact that the cursor checks the flag of its subscription to
see if it should stay active when its stop method is called. The
subscription needs to disable that flag when the subscription is being
removed so that the cursor will correctly shutdown.
A QueueBrowser no longer checks expiry on messages to prevent a
browser from hanging in between the hasMoreElements check and actually
getting a message. This means that if messages were in the queue when
the browser started it will receive messages even if they are now
expired. Even though the browser will get the expired message, the
broker will still expire it to prevent future access to it.
Thanks to Henno Vermeulen for providing a test case.
This commit is based off a patch submitted by admin@int3solutions.com.
It fixes several locations in the code where there are potential resource leaks.
fix for incorrect logic in reconnect attempt limits and also fix a case
where an NPE could occur (saw in the tests). Based on patch provided
by Benoit Wiart
Introduce OpenWire v11 which adds noLocal to the SubscriptionInfo, if
configured KahaDB can store that version and the noLocal value is
recovered from the store.
Adding a new property on PolicyEntry called includeBodyForAdvisory which will
include the original message body when sending advisory messages that include
the original message, instead of clearing it out. This is turned off by
default.
Adding a property called schedulePeriodForDiskUsageCheck which can be set
to a time period to periodically check disk usage limits and adjust if
the amount of disk space has been reduced.
Don't dip into the store to recover durable topic subscriptions or queue
subscriptions depending on the subscription strategy in use. The needed
information is always kept in either TopicRegion or QueueRegion even
after restart as all stored destinations are reloaded as the broker is
started.
