FineGrainedAtomicMap implementation fails to consider removal of elements ------------------------------------------------------------------------- Key: ISPN-2149 URL: https://issues.jboss.org/browse/ISPN-2149 Project: Infinispan Issue Type: Bug Components: Core API Affects Versions: 5.1.5.FINAL, 5.2.0.ALPHA1 Reporter: Sanne Grinovero Assignee: Vladimir Blagojevic Priority: Blocker Labels: affects_OGM Fix For: 5.2.0.Alpha4, 5.2.0.Final Most methods in the {{org.infinispan.atomic.FineGrainedAtomicHashMapProxy<K, V>}} implementation seem to ignore the use case of removing keys from the map. {{keySet()}}, {{values()}}, {{entrySet()}}, {{size()}}, {{isEmpty()}} all ignore the fact that values in the uncommitted map might have been *removed* in the current transaction, or have *intersections* with existing keys. Note that failing to consider intersections has it return the wrong entries as committed values overwrite the in-flight values. Methods like {{containsKey}} don't check if the matched key is in fact stored in the {{DeltaAwareCacheEntry}} as a deleted entry.
