Fix intermittent test failures in pull consumer test by asserting that there
are the expected number of message on the queue before running the JMS consume
cycle to consume credit and trigger federation credit to flow.
Tests need to ensure federation links are up before sending to and address
or the sent message can get discarded before the federation consumer is there
to receive it.
When federation is configured in two directions between nodes for an address
the message can reflect from one node to another if max hops is not set or not
set correctly and in some federation topologies the max hops value can't solve
the issue and still result in a working configuration. This reflection should
be prevented at the federation consumer level for address consumers.
These tests are using an asynchronous feature. the check on Log has to use the Wait.assertEquals
I had to make a few changes to the methods to allow the use of Wait
Generate MQTT message IDs from full allowed range of 1-65535 and skip

little tool showing current folders on the CLI. Useful to figure out where you're at when using the shell.
I get myself typing pwd all the time I am using the CLI, trying to figure out what is my current location and broker being used.
this would be useful to make sure you are going to use the right broker when multiple CLI instances are running from multiple terminals.
When Queue consumers attach with filters use those instead of the Queue
filter to filter the messages that are federated to avoid stranding of
messages on the local broker. This will result in multiple federation
consumers if the various attached local consumers all use different
filters but does keep unwanted messages on the remote so that consumers
there can consume those.
Under some scenarios federation demand tracking is losing track of total demand
for a federated resource leading to teardown of federated links before all local
demand has been removed from the resource. This occurs most often if the attempts
to establish a federation link are refused because the resource hasn't yet been
created and an eventual attach succeeds, but can also occur in combination with
a plugin blocking or not blocking federation link creation in some cases.
Large message support was added to
o.a.a.a.c.s.f.FederatedQueueConsumerImpl#onMessage via cf85d35 for
ARTEMIS-3308. The problem with that change is that when onMessage
returns o.a.a.a.c.c.i.ClientConsumerImpl#callOnMessage will eventually
call o.a.a.a.c.c.i.ClientLargeMessageImpl#discardBody which eventually
ends up in o.a.a.a.c.c.i.LargeMessageControllerImpl#popPacket waiting 30
seconds (i.e. the default readTimeout) for more packets to arrive (which
never do). This happens because the FederatedQueueConsumer short-cuts
the "normal" process by using LargeMessageControllerImpl#take.
This commit fixes that by tracking the number of bytes "taken" and then
looking at that value later when discarding the body effectively
skipping the 30 second wait.
When an AMQP federation instance attempts to federate an address or queue
it can fail if the remote address or queue is not present or cannot be
created based on broker policy. A federation link can also closed if the
federated resource is removed from the remote broker by management etc.
In those cases the remote broker should note the resources that were
targets of federation and send alerts to the source federation broker to
notify it that these resources become available for federation and the
source should attempt again to create federation links if demand still
exists. This allows an AMQP federation instance to heal itself based on
updates from the remote.
No problems reported on this test.
I needed to validate rather if messages were being distributed correctly when either SNF or the final address itself was paged. Rather than throw away the test I decided to keep the validation here.
In rare cases the status is returning 'running' to a process that is
not Artemis. It was create a extra level of verification by validating
if the running process working directory is the
same of ${ARTEMIS_INSTANCE}.
