When using a temporary queue with a `temporary-queue-namespace` the
`AddressSettings` lookup wasn't correct. This commit fixes that and
refactors `QueueImpl` a bit so that it holds a copy of its
`AddressSettings` rather than looking them up all the time. If any
relevant `AddressSettings` changes the
`HierarchicalRepositoryChangeListener` implementation will still
refresh the `QueueImpl` appropriately.
The `QueueControlImpl` was likewise changed to get the dead-letter
address and expiry address directly from the `QueueImpl` rather than
looking them up in the `AddressSettings` repository.
I modified some code that came from ARTEMIS-734, but I ran the test that
was associated with that Jira (i.e.
`o.a.a.a.t.i.c.d.ExpireWhileLoadBalanceTest`) and it passed so I think
that should be fine. There actually was no test included with the
original commit. One was added later so it's hard to say for sure it
exactly captures the original issue.
It sometimes makes sense to set an acceptor's port to 0 to allow the JVM
to select an ephemeral port (e.g. in embedded integration tests). This
commit adds a new getter on NettyAcceptor so tests can programmtically
determine the actual port used by the acceptor.
This commit also changes the ACCEPTOR_STARTED notification and the
related logging to clarify the actual port value where clients can
connect.
The auto-create-jms-queues, auto-delete-jms-queues,
auto-create-jms-topics, and auto-delete-jms-topics address settings
were deprecated in ARTEMIS-881 way back in 2016. There's no need to keep
them in the default broker.xml at this point.
JGroups 3.x hasn't been updated in some time now. The last release was
in April 2020 almost 2 years ago. Lots of protocols have been updated
and added and users are wanting to use them. There is also increasing
concern about using older components triggered mainly by other
recently-discovered high-profile vulnerabilities in the wider Open
Source Java community.
This commit bumps JGroups up to the latest release - 5.2.0.Final.
However, there is a cost associated with upgrading.
The old-style properties configuration is no longer supported. I think
it's unlikely that end-users are leveraging this because it is not
exposed via broker.xml. The JGroups XML configuration has been around
for a long time, is widely adopted, and is still supported. I expect
most (if not all) users are using this. However, a handful of tests
needed to be updated and/or removed to deal with this absence.
Some protocols and/or protocol properties are no longer supported. This
means that users may have to change their JGroups stack configurations
when they upgrade. For example, our own clustered-jgroups example had to
be updated or it wouldn't run properly.
MQTT 5 is an OASIS standard which debuted in March 2019. It boasts
numerous improvments over its predecessor (i.e. MQTT 3.1.1) which will
benefit users. These improvements are summarized in the specification
at:
https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html#_Toc3901293
The specification describes all the behavior necessary for a client or
server to conform. The spec is highlighted with special "normative"
conformance statements which distill the descriptions into concise
terms. The specification provides a helpful summary of all these
statements. See:
https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html#_Toc3901292
This commit implements all of the mandatory elements from the
specification and provides tests which are identified using the
corresponding normative conformance statement. All normative
conformance statements either have an explicit test or are noted in
comments with an explanation of why an explicit test doesn't exist. See
org.apache.activemq.artemis.tests.integration.mqtt5 for all those
details.
This commit also includes documentation about how to configure
everything related to the new MQTT 5 features.
The address-setting config-delete-diverts is not being applied correctly
hierarchically because it's not included in the merge() method. It is
also not being persisted to disk either. This commit fixes both issues.
scenario - avoid paging, if address is full chain another broker and produce to the head, consume from the tail using producer and consumer roles to partition connections. When tail is drained, drop it.
- adds a option to treat an idle consumer as slow
- adds basic support for credit based address blocking ARTEMIS-2097
- adds some more visiblity to address memory usage and balancer attribute modifier operations
