This commit fixes the following things:
- Moves connection audit logging to the resource audit logger instead
of using a dedicated logger as that would adversely impact upgrading
users, and arguably didn't make sense in the first place.
- Mitigates an potential NPE w.r.t. connection ID.
- Updates the "dummy" management connection to return a valid
connection ID.
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.
I am adding three attributes to Address-settings:
* page-limit-bytes: Number of bytes. We will convert this metric into max number of pages internally by dividing max-bytes / page-size. It will allow a max based on an estimate.
* page-limit-messages: Number of messages
* page-full-message-policy: fail or drop
We will now allow paging, until these max values and then fail or drop messages.
Once these values are retracted, the address will remain full until a period where cleanup is kicked in by paging. So these values may have a certain delay on being applied, but they should always be cleared once cleanup happened.
I am adding an option sync=true or false on mirror. if sync, any client blocking operation will wait a roundtrip to the mirror
acting like a sync replica.
Some LDAP servers (e.g. OpenLDAP) do not support the "persistent search"
feature and therefore the existing "listener" feature does not actually
fetch updates. This commit implements a "pull" feature controlled by a
configurable interval equivalent to what is implemented in the cached
LDAP authorization module from ActiveMQ "Classic."
Adds a new module 'artemis-junit-5' which adds JUnit 5 Extensions for
unit testing. For backwards compability, 'artemis-junit' still uses
JUnit 4. Common stuff has been moved to 'artemis-junit-commons'. Work is
based on the initial PR

Sometimes users want to perform custom client ID validation, and in the
case of an invalid client ID the proper reason code should be returned
in the CONNACK packet.
Currently the broker detects the presence of the web console by looking
for the name of a file (i.e. console.war). This is fragile because if
the file is renamed for any reason then the broker won't print the
status of the web console when it starts.
This commit improves web console detection by inspecting the
<display-name> tag in the war file's WEB-INF/web.xml. By default it
looks for "hawtio", but this can be customized using the system property
"org.apache.activemq.artemis.webConsoleDisplayName".
MQTT 3.1 and 3.1.1 clients using a clean session should have a
*non-durable* subscription queue. If the broker restarts the queue
should be removed. This is due to [MQTT-3.1.2-6] which states that the
session (and any state) must last only as long as the network
connection.
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.
Allow replication only certain addresses with mirror controller.
The configuration is similar to cluster address configuration.
