Adjust slow-consumer detection logic to use the number of messages in
the queue and not just the number of messages added since the last
check. This means the getRate() method now returns the rate of messages
which it *could* have dispatched since the last check rather than the
rate at which it received messages. This is a more reliable metric to
ensure the slow-consumer detection logic doesn't flag a consumer as
slow unfairly. Although the reliability will come at a performance cost
since getMessageCount() must lock the queue.
As part of my refactoring on AMQP, the broker shouldn't rely on Application properties
for any broker semantic changes on delivery.
I am removing any access to those now, so we can properly deal with this post 2.0.0.
Artemis expose createQueue() method to management console like Jon.
If the queue to be created already exists it throws an ActiveMQException
back to the console, which will get a ClassNotFoundException when
deserializing the exception.
The same issue goes also with AddressControl.sendMessage() method.
To fix that it should throw a common java exception like IllegalStateException.
with this we could send and receive message in their raw format,
without requiring conversions to Core.
- MessageImpl and ServerMessage are removed as part of this
- AMQPMessage and CoreMessage will have the specialized message format for each protocol
- The protocol manager is now responsible to send the message
- The message will provide an encoder for journal and paging
When openwire sends back an exception response, it doesn't set
the correct correlation id. This causes the client to miss the
response and the exception won't get caught.
To fix it we need to add the correlation id before sending.
When sending an empty ObjectMessage, broker doesn't
write a 'length' field to the message buffer. In delivery
the broker tries to read the length from the buffer, which
causes "IndexOutOfBoundsException".
To fix it, we need to check if the buffer is empty or not,
and only read it if the buffer is not empty.
When a producer sends a messages to a temp destination created from
another connection, it fails. The reason behind it is that the
producer's connection didn't receive the advisory message (notification)
from broker about this temp destination, and it will throw an exception
if it doesn't know this temp destination.
The fix is send the advisory to the client so that it knows this destination.
When creating a 'no-local' openwire consumer, it doesn't work,
meaning it can still receive messages from the same connection.
The fix is similar to what Artemis client does, which is adding
a 'filter' to the consumer/subscription.
The difference is that with OpenWire we have to do it on the
broker side.
Adds tests for handling of Rejected, Released and Modified outcomes for
a delivery sent to a receiver. Tests show that for the Modified outcome
the broker is redelivering the message to the same receiver when the
undeliverable here value is set which violates the AMQP 1.0 specified
handling of that field. Also for Rejected outcome the broker should
be sending the rejected message to the DLQ as Rejected is supposed to
be a terminal outcome.
Small fix included to not adjust the delivery count if the Modified
outcome does not indicate that the delivery failed.
