> AMQP: Problems with durable Topic subscription handling
> -------------------------------------------------------
>
> Key: ARTEMIS-799
> URL: https://issues.apache.org/jira/browse/ARTEMIS-799
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: AMQP
> Affects Versions: 1.4.0
> Reporter: Timothy Bish
>
> Handling of durable topic (pub/sub) subscription has a few issues:
> * Cannot reattach a durable subscription from the same connection where one
> was previously attached and then detached
> * A native AMQP client cannot remove a durable subscription it created simply
> by closing the link that created the subscription, it must close the link.
> lookup to subscription and then close the link again, although probably from
> a different connection given the issue above.
> * When an existing durable topic subscription is looked up it does not return
> in to the client the selector or noLocal filter that was previously
> configured on the connection which allows the client to rightly assume that
> what it got is not the original subscription it created.
> * Detached links are not freed (closed sessions aren't either) which leads to
> a slow memory leak given that the broker doesn't ever expect to recover these.
