Locking interceptor should check the topology before acquiring locks -------------------------------------------------------------------- Key: ISPN-10041 URL: https://issues.jboss.org/browse/ISPN-10041 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.2.11.Final, 9.3.6.Final, 10.0.0.Beta2, 9.4.9.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 10.0.0.Beta4 The distribution interceptors check the command topology is the same as the current topology before sending a command to remote nodes, but the locking interceptors do not have any check. On a remote node, this means the inbound invocation handler acquires some locks in topology {{T}}, then the locking interceptor acquires other locks in topology {{T+1}}, and finally the distribution interceptor throws {{OutdatedTopologyException}} and releases the locks. In older versions there is also a potential for blocking a remote executor thread while waiting for the lock, but luckily that is not a problem in 9.4+. It would be more efficient if the locking interceptor was throwing {{OutdatedTopologyException}} instead.
