[jboss-jira] [JBoss JIRA] Closed: (JBCLUSTER-223) Support for distributed locking

Support for distributed locking ------------------------------- Key: JBCLUSTER-223 URL: https://jira.jboss.org/browse/JBCLUSTER-223 Project: JBoss Clustering Issue Type: Feature Request Security Level: Public(Everyone can see) Components: HA-Server-API Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: HA-Server-API 2.0.0.Beta1 Useful for clustered DeploymentRepository and for ensuring only one node accesses a web session or SFSB at a time. This actually exists in JBoss AS cluster module, so this JIRA is largely about extracting it out of the AS codebase. This is different from the JGroups DistributedLockManager isn two main respects: 1) Built on HAPartition instead of RpcDispatcher. This is actually a negative, but I want this to be able to use the same channel the AS's HAPartition uses. Perhaps we'll develop a separate API and an adapter implementation that directly uses RpcDispatcher to provide flexibility going forward (see JBAS-7850). 2) Acquiring a lock requires a callout to a pluggable LocalLockHandler. This is to support more sophisticated interaction with the service using the lock manager. It doesn't use the two-phase approach the JGroups DistributedLockManager adopts either.
