The OpenTelemetry dependencies can be isolated to the `opentelemetry`
example in the `activemq-artemis-examples` repo. They aren't needed here
anymore.
Currently when an MQTT topic filter contains characters from the
configured wildcard syntax the conversion to/from this syntax breaks.
For example, when using the default wildcard syntax if an MQTT topic
filter contains a . the conversion from the MQTT wildcard syntax to the
core wildcard syntax and back will result in the `.` being replaced with
a `/.`.
This commit fixes that plus a few other things...
- Implements proper conversions to/from one WildcardConfiguration to
another.
- Refactors the MQTT code which invokes these conversion methods. This
includes simplifying a lot of test code.
- Adds lots of tests for everything.
- Clarifies some variable naming to better distinguish between core and
MQTT.
- Move ActiveMQTestBase to artemis-test-support.
- Add reduced parent for current artemis-server tests.
- Add a simpler test case parent class unit tests can use.
- Convert some existing checks into a rule for reuse.
- Move various rules/utils to artemis[-unit]-test-support module from where they can be used instead of from artemis-server.
This commit:
- Eliminates MQTT session storage on every successful connection.
Instead data is only written when subsriptions are created or
destroyed.
- Adds a configuration property for the storage timeout.
- Updates the documentation with relevant information.
- Refactors a few bits of code to eliminate unnecessary variables, etc.
If both scale-down and cluster-connection are using the same JGroups
discovery-group then when the cluster-connection stops it will close the
underlying org.jgroups.JChannel and when the scale-down process tries to
use it to find a server it will fail.
This commit ensures that the JGroupsBroadcastEndpoint implementation of
BroadcastEndpoint#openClient initializes the channel if it has been
closed.
Change from forcing a session start cycle on each consumer add
event and start only those consumers that were added which will
trigger a prompt delivery action on each. The session should be
marked started on create to account for the remove of the start
on each consumer add event.
PagingStroeImpl.checkReleasedMemory() will kick off
executor.execute(this::memoryReleased) to pull from the queue onMemoryFreedRunnables
asynchronously. If the executor fires the task too late, it can pick up one of the
late trackMemoryChecks runnable and increase its calls, making assertion fail.

When we know that a node leaves a clustercleanly we shouldn't log WARN
messages about it.

If the broker is embedded into a Jakarta environment then the existing
artemis-openwire-protocol module won't work because it uses javax
classes.
This commit adds a new Jakarta-specific module that can be used to
support OpenWire clients in Jakarta environments (e.g. Spring Boot 3).
Users will simply need to include this version on their classpath to
enable support.
Allows the configuration of AMQP Federation broker connections to be updated and
reloaded. This allows for update, add or remove of AMQP federation broker connections
as well as the basic AMQP sender and receiver broker connections. It checks for and
ignores changes in AMQP broker connections that are performing Mirroring as that
would lead to issues that can break mirroring.
I just did some static analysis of this code, and I believe it would be better to first add to the list
before setting the cancel task.
Reason for that is in case the Runnable is dequeued between the add in the deQueue and setting the cancel task.
Possibility is remote but my OCD wouldn't let me ignore this small possibility.
There is a race condition between ConnectionEntry.ttl and
FailureCheckAndFlushThread whereby an in-vm connection may get closed
inadvertently due to a TTL timeout. This is because ConnectionEntry.ttl
is initialized to 60000 and then later set to -1 upon the initial Ping.
If this update happens at *just* the right time in
FailureCheckAndFlushThread then the connection will be closed.
The fix ensures that the ConnectionEntry.ttl is set to -1 for in-vm
connections from the start. It also eliminates the possibility of the
race in FailureCheckAndFlushThread.
This fix is based on static analysis of the code. The timing window is
just too small to contruct a reliable test. The failure has only been
seen in the wild a handful of times.
When initially developed the expectation was that no more producers would keep connecting but in a scenario like this
the consumers could actually give up and things will just accumulate on the server.
We should cleanup these upon disconnect.
Mirror acks should be performed atomically with the storage of the source ACK. Both the send of the ack and the recording of the ack should be part of the same transaction (in case of transactional).
We are also adding support on transactions for an afterWired callback for the proper plug of OperationContext sync.
