Due to the changes in 682f505e32 we now
send "Last Will & Testament" MQTT messages via ServerSession. This means
sending will fail if the disk is full. For MQTT this triggers a
connection failure which in turns triggers sending an LWT message. This
process will recurse infinitely until it results in a
java.lang.StackOverflowError.
This commit fixes that by tracking whether or not sending a LWT message
is already in progress.
org.apache.activemq.artemis.spi.core.protocol.RemotingConnection has a
number of implementations most notably an abstract version which
provides many methods shared among the implementations. The sharing
could be improved to eliminate duplicate code.
This commit eliminates more than 700 lines of unnecessary code.
There should be no semantic changes.
When a message is sent to an anycast queue via FQQN on one node of a
cluster and then a consumer is created on that same anycast queue via
FQQN on another node in the cluster the message is not redistributed to
the node with the consumer.
This commit fixes this use-case primarily by including the FQQN info in
the notification messages sent to other nodes in the cluster.
Messages without a last-value property sent to an LVQ are being pruned
rather than just passing through. Only messages with a non-null
last-value property should be subject to pruning.
Running HorizontalPagingTest with these variables would make the test to fail unless these changes are applied.

We were lucky that processReferences was pretty much a static operation, hence I am moving it away from RoutingContext both for clarity and avoiding state being needed on that method.
If state was needed as part of processReferences you would had a pretty nasty bug as the IOCallback could introduce a race where a send would change the state while the IO was pending.
Both audit logging and logging from the LoggingActiveMQServerPlugin are
unclear as they relate to transactional sends and acks. Both essentially
ignore the transaction which makes it appear that an operation has taken
place when, in fact, it hasn't (e.g. a transactional ack is rolled back
but the log indicates the ack went through).
This commit fix this with the following changes:
- Log details when a send or ack is added to a transaction.
- Log details when the transaction is committed.
- Log when the transaction is rolled back.
- Include transaction details in the relevant DEBUG logs.
- Simplify INFO level logging for sends & acks in
LoggingActiveMQServerPlugin. Ensure details are in the DEBUG logs.
Other changes:
- Make capitalization more consistent in a handful of audit logs.
AddressControl has 2 methods to get same metric. Both
getNumberOfMessages() and getMessageCount() return the same metric
albeit in different ways.
Also, getNumberOfMessages() inspects both "local" and "remote" queue
bindings which is wrong.
This commit fixes these issues via the following changes:
- Deprecate getNumberOfMessages().
- Change getNumberOfMessages() to invoke getMessageCount().
- Add a test to ensure getNumberOfMessages() does not count remote
queue bindings.
- Simplify getMessageCount(DurabilityType).
This is caused by too many entries on the HashMap for ThreadLocals.
Also: I'm reviewing some readlock usage on the StorageManager to simplify things a little bit.
It would be useful to be able to cycle the embedded web server if, for
example, one needed to renew the SSL certificates. To support
functionality I made a handful of changes, e.g.:
- Refactoring WebServerComponent so that all the necessary
configuration would happen in the start() method.
- Refactoring WebServerComponentTest to re-use code.
