Dan Berindei created ISPN-4444: ---------------------------------- Summary: After state transfer, a node is able to read keys it no longer owns from its data container Key: ISPN-4444 URL: https://issues.jboss.org/browse/ISPN-4444 Project: Infinispan Issue Type: Bug Security Level: Public (Everyone can see) Components: Core, State Transfer Affects Versions: 7.0.0.Alpha4 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Critical Fix For: 7.0.0.Final When state transfer ends and each node receives a CH_UPDATE command from the coordinator, it first installs the new topology and then it starts invalidating entries it no longer owns. However, there are two cases when the node can still read its stale values: 1. If L1 is enabled, it will look in the local DataContainer first, regardless of the key's location. 2. If L1 is disabled, but the key was removed on the new owners, the node will still look up the key in the local DataContainer after receiving a null response. The problem can be reproduced with {{TxReadAfterLosingOwnershipTest}} and its subclasses, by replacing the {{operation.update(cache(1));}} line with {{operation.update(cache(0));}} -- This message was sent by Atlassian JIRA (v6.2.6#6264)
