[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1341) Eviction treats FIFO as LRU

Eviction treats FIFO as LRU --------------------------- Key: ISPN-1341 URL: https://issues.jboss.org/browse/ISPN-1341 Project: Infinispan Issue Type: Bug Components: Eviction Affects Versions: 5.0.0.FINAL Reporter: Jozef Vilkolak Assignee: Manik Surtani When a cache is created with eviction strategy set to FIFO it is actually treated as being LRU. This can be seen in org.infinispan.container.DefaultDataContainer.java. Functional test for FIFO eviction can be found at [https://svn.devel.redhat.com/repos/jboss-qa/edg/edg-functional-tests/trunk/] in the eviction-strategy module. Basically what the test does is insert 3 values into the cache then retrieves the first value(to differentiate FIFO and LRU) and inserts 4th value which sets eviction in motion because of maxEntries=3. I would expect the first entered value ("A") to be evicted instead it evicts the second ("B"). It uses the following cache configuration: {code:xml} <local-cache name="fifo" start="EAGER" batching="false" indexing="NONE"> <locking isolation="REPEATABLE_READ" acquire-timeout="20000" concurrency-level="500" striping="false" /> <eviction strategy="FIFO" max-entries="3" interval="2000"/> </local-cache> {code}
