[jira] [Commented] (QPID-7138) [Java Broker] Broker should detect
duplicate IDs in configured objects
[ https://issues.apache.org/jira/browse/QPID-7138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15241023#comment-15241023 ]
Keith Wall commented on QPID-7138:
----------------------------------
Change {{ACO#onOpen()} to locate the tree's root, and then traverse the whole tree looking for a duplicate UUIDs. If a duplicate UUID is encountered then the object should go into an ERRORed state. We need to ensure that two virtualhosts, racing cannot both succeed in adding say a Queue with the same UUID to the tree at the same moment. This might require that we hold global lock whilst registering a child's UUID, or traversing the tree.

> Key: QPID-7138
> URL: https://issues.apache.org/jira/browse/QPID-7138
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Affects Versions: 0.28, 0.30, 0.32, qpid-java-6.0, qpid-java-6.0.1
> Reporter: Alex Rudyy
> Fix For: qpid-java-6.1

> Currently UUID uniqueness is enforced only amongst immediate siblings. This means that, say, a virtual host with queue with UUID A would reject a second queue with the same UUID A. Currently if a second virtual host had a queue with same UUID A, this would be allowed. This presents a problem for clients (including the Web Management Console) that expect UUID to be universally unique.
> Change ACO so that object UUID are universally so. The validatation would need to be applied as new objects are created, as the Broker starts up and as Virtualhosts are recovered. This latter may or may not be at start-up time.
