----------------------------------
Summary: State transfer doesn't replace L1 entry with regular entry
Key: ISPN-8237
URL: https://issues.jboss.org/browse/ISPN-8237
Project: Infinispan
Issue Type: Bug
Components: Core
Affects Versions: 9.1.0.Final
Reporter: Dan Berindei
Assignee: Dan Berindei
An L1 entry is preserved when the local node becomes an owner, it is only removed if the application removes the key explicitly. Otherwise state transfer overwrites the L1 entry with the entry received from a previous owner, making it immortal (assuming the original entry didn't have a lifespan/maxIdle).
A transaction writing to a key while the local node is only a write owner will not remove the L1 metadata from the entry either, but it will set the {{PUT_FOR_STATE_TRANSFER}} flag in {{CommitManager}}. Since state transfer doesn't overwrite an entry tracked in {{CommitManager}}, that means the L1 entry is never replaced with an immortal entry.
This started appearing in {{ConcurrentNonOverlappingLeaveTest}} once I changed {{TxDistributionInterceptor}} to cause a retry when the topology changes during commit (for ISPN-8195). There, the entry is first wrapped on the originator before it becomes the primary owner, and the commit happens multiple times, but neither seems to be required.
