When resource audit logging is enabled STOMP is completely inoperable
due to an NPE during the protocol handshake. Unfortunately the failure
is completely silent. There are no logs to indicate a problem.
This commit fixes this problem via the following changes:
- Mitigate the original NPE via a check for null
- Move the logic necessary to set the "protocol connection" on the
"transport connection" to a class shared by all implementations.
- Add exception handling to log failures like this in the future.
- Add tests to ensure the audit logging is correct.
Continually read from the compressed byte[] into
the decompressed object
Add test to validate large (>1024 bytes) compressed data can be
deserialized properly
During redistribution, we should not copy all message annotations.
In particular we should not copy any of the x-opt-ORIG annotations used on DLQ and other copies.
this was broken after f632e8104b (ARTEMIS-3833 Preserve JMSCorrelationID of distributed AMQP large messages)
The change preserved too much, and as a result of that AmqpLargeMessageRedistributionTest::testSendMessageToBroker0GetFromBroker2 is intermittently failing.
There is no test in this commit as this is fixing AmqpLargeMessageRedistributionTest
When sending, for example, to a predefined anycast address and queue
from a multicast (JMS topic) producer, the routed count on the address
is incremented, but the message count on the matching queue is not. No
indication is given at the client end that the messages failed to get
routed - the messages are just silently dropped.
Fixing this problem requires a slight semantic change. The broker is now
more strict in what it allows specifically with regards to
auto-creation. If, for example, a JMS application attempts to send a
message to a topic and the corresponding multicast address doesn't exist
already or the broker cannot automatically create it or update it then
sending the message will fail.
Also, part of this commit moves a chunk of auto-create logic into
ServerSession and adds an enum for auto-create results. Aside from
helping fix this specific issue this can serve as a foundation for
de-duplicating the auto-create logic spread across many of the protocol
implementations.
- activemq.notifications are being transferred to the target node, unless an ignore is setup
- topics are being duplicated after redistribution
- topics sends are being duplicated when a 2 node cluster mirrors to another 2 node cluster, and both nodes are mirrored.
- interrupted message breaking reference counting
After the server writing to the client is interrupted in AMQP, the reference counting was broken what would require the server restarted
in order to cleanup the files of any interrupted sends.
- Removed consumer during large message delivery damaging large messages
If the consumer failed to deliver messages for any reason, the message on the queue would be duplicated. what would wipe out the body of the message
and other journal errors would happen because of this.
extra debug capabilities added into RefCountMessage as part of ARTEMIS-4206 in order to identify these issues
This fix is scanning journal and paging for existing large messages. We will remove any large messages that do not have a corresponding record in journals or paging.
there are two leaks here:
* QueueImpl::delivery might create a new iterator if a delivery happens right after a consumer was removed, and that iterator might belog to a consumer that was already closed
as a result of that, the iterator may leak messages and hold references until a reboot is done. I have seen scenarios where messages would not be dleivered because of this.
* ProtonTransaction holding references: the last transaction might hold messages in the memory longer than expected. In tests I have performed the messages were accumulating in memory. and I cleared it here.
o.a.a.a.c.p.o.a.AMQConsumer#init will *always* try to create a core
queue when creating a consumer for a JMS queue. However, this is
already done in o.a.a.a.c.p.o.a.AMQSession#createConsumer.
The issue identified with AMQP was under Transaction usage, and while opening and closing sessions.
It seems the leak would be released once the connection is closed.
We added a new testsuite under ./tests/leak-tests To fix and validate these issues
For pipelined open cases the events processing should ignore additional begin
and attach events if the open event handler closes the connection to avoid the
processing throwing additional exceptions and replacing the error condition in
the connection with an unrelated error about NPE from the additional events.
o.a.a.a.c.p.m.MQTTSubscriptionManager#removeSubscription() had a chunk
of code from 971f673c60 removed. That code
was added under the assumption that there should only ever be one
consumer per queue. That was true for MQTT 3.x, but it's not always true
for MQTT 5 due to shared subscriptions. However, the tests from that
commit all still pass even with it removed now (as well as all the other
MQTT tests) so I think it's safe.
If the client is using address prefixes to define the routing type along with
durable subscriptions then on re-attach the compairon to check if the subscription
address has changed needs to remove the prefix when comparing against the address
since the prefix isn't propagated when creating the address and will always fail
resulting in the subscription queue being deleted in error.
When an AMQP client subscribes to a new address (non-existing) with a receiver link, the
address is created with routing type ANYCAST regardles of the default address creation
configuration of the broker, and ignores even the broker wide default of MULTICAST.
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.
