QPID-7658: [Java Broker] Improve LinkRegistry. Propagate errors during attach
back to remote endpoint.
> [Java Broker] Improve LinkRegistry
> ----------------------------------
>
> Key: QPID-7658
> URL: https://issues.apache.org/jira/browse/QPID-7658
> Project: Qpid
> Issue Type: Task
> Components: Java Broker
> Reporter: Lorenz Quack
> Fix For: qpid-java-broker-7.0.0
>
>
> Currently the AbstractVirtualHost has a Map<remoteContainerId, LinkRegistry>.
> The handling of the remoteContainerId should also be encapsulated in the
> LinkRegistry giving each VH only a single LinkRegistry.
> The LinkRegistry is responsible for ensuring Link uniqueness and persistence
> (separate JIRA).
> Furthermore, the following change to the LinkRegistry is proposed:
> * LinkRegistry.getSendvingLink(String remoteContrainerId, String linkName) ->
> Link
> * LinkRegistry.getReceivingLink(String remoteContrainerId, String linkName)
> -> Link
> These should always return a non-null Link. The caller (session) is
> responsible for checking that the link has valid Source and Targets.
> They also need to be thread-safe (e.g., two calls with the same arguments
> should return the same object).
> The LinkRegistry should also provide facilities to the Link to remove itself
> from the Registry (for example on Link close, or error) and to update the
> Termini upon resuming a Link.
> If possible this should not be part of the public API. possible API:
> * LinkRegistry.removeSendingLink(String localContainerId, String
> remoteContrainerId, String linkName)
> * LinkRegistry.removeReceivingLink(String localContainerId, String
> remoteContrainerId, String linkName)
> * LinkRegistry.updateLinkTermini(Link link, Source source, Target target)
> The implementation of which must be thread-safe because the LinkRegistry will
> be accessed on multiple threads concurrently.
