[jira] [Updated] (QPID-2576) Standardise queue Ownership across
protocols
[ https://issues.apache.org/jira/browse/QPID-2576?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Justin Ross updated QPID-2576:
------------------------------
Component/s: Java Broker
> Standardise queue Ownership across protocols
> --------------------------------------------
>
> Key: QPID-2576
> URL: https://issues.apache.org/jira/browse/QPID-2576
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Martin Ritchie
> Assignee: Martin Ritchie
>
> Currently the broker does not have a consistent view of who the queue Owner is. The 0-8/0-9/0-91 code path uses client id.
> The 0-10 code path uses the authenticated user name.
> In a number of locations such as:
> DerbyMessageStore uses the authenticated Principal name.
> QueueDeclareHandler compares principal name against getOwner for exclusive queue checks.
> (This will only work if a 0-10 client created the queue as it will set the owner name to the principal name, see sub jira on this issue)
> From the JMS Spec 4.3.2
> The purpose of the client identifier is to associate a connection and its objects
> with a state maintained on behalf of the client by a provider. By definition, the
> client state identified by a client identifier can be `in use' by only one client at
> a time. A JMS provider must prevent concurrently executing clients from using
> it.
> Which suggests that it could be used to perform exclusive queue detection rather than the authenticated user that could log in more than once. This will need more discussion on dev.
> First step is to ensure the code all uses getOwner even if the 0-10 version currently sets that to the authenticated Principal.
