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
Components: Core, State Transfer
Affects Versions: 7.0.0.Alpha4
Reporter: Dan Berindei
Priority: Critical
Fix For: 7.1.0.Alpha1
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));}}
