I have seen a werid intermittent failure in the testsuite
caused by some race where the EMPTY_SET ends up Not Empty! Causing weird failures that were really difficult to be investigated
This fix is scanning journal and paging for existing large messages. We will remove any large messages that do not have a corresponding record in journals or paging.
This failure was because of a noise from the test itself. as the test is creating a producer, and it's measuring for a producer from the test.
it makes no sense to fix it for OverCore.. we just ignore it on UsingCore
This is just an annoying thing. as the functionality would work properly if there was a previous value.
No other harm other than the cannot find TX record on startup for this, hence I'm fixing it.
Fixes the CompareUpgradeTest by removing this unimportant difference from a fresh broker instances jolokia-access.xml file, given that we dont actually update jolokia-access.xml currently during upgrade.
Tweaks or unwinds earlier changes in aae65fd527 and 3e7cb24381
There are certain use-cases where addresses will be auto-created and
never have a direct binding created on them. Because of this they will
never be auto-deleted. If a large number of these addresses build up
they will consume a problematic amount of heap space.
One specific example of this use-case is an MQTT subscriber with a
wild-card subscription and a large number of MQTT producers sending one
or two messages a large number of different MQTT topics covered by the
wild-card. Since no bindings are ever created on any of these individual
addresses (e.g. from a subscription queue) they will never be
auto-deleted, but they will eventually consume a large amount of heap.
The only way to deal with these addresses is to manually delete them.
There are also situations where queues may be created and never have
any messages sent to them or never have a consumer connect. These
queues will never be auto-deleted so they must be deleted manually.
This commit adds the ability to configure the broker to skip the usage
check so that these kinds of addresses and queues can be deleted
automatically.
there are two leaks here:
* QueueImpl::delivery might create a new iterator if a delivery happens right after a consumer was removed, and that iterator might belog to a consumer that was already closed
as a result of that, the iterator may leak messages and hold references until a reboot is done. I have seen scenarios where messages would not be dleivered because of this.
* ProtonTransaction holding references: the last transaction might hold messages in the memory longer than expected. In tests I have performed the messages were accumulating in memory. and I cleared it here.
Previously, the code added a comment with the host name in it.
Sometimes hostnames don't follow the xml standards for comments.
Specifically, having a double dash ("--") in the host name would cause
an error when jolokia tried to load the config file - because it was
invalid xml.
The simple solution was to not put the host name into the comment.
A unit test has been included to ensure the same thing doesn't happen in the
future.

o.a.a.a.c.p.o.a.AMQConsumer#init will *always* try to create a core
queue when creating a consumer for a JMS queue. However, this is
already done in o.a.a.a.c.p.o.a.AMQSession#createConsumer.
The issue identified with AMQP was under Transaction usage, and while opening and closing sessions.
It seems the leak would be released once the connection is closed.
We added a new testsuite under ./tests/leak-tests To fix and validate these issues
