[infinispan-issues] [JBoss JIRA] (ISPN-2546) StateChunk with isLastChunk=true not sent when all entries are sent ahead

StateChunk with isLastChunk=true not sent when all entries are sent ahead ------------------------------------------------------------------------- Key: ISPN-2546 URL: https://issues.jboss.org/browse/ISPN-2546 Project: Infinispan Issue Type: Bug Components: State transfer Affects Versions: 5.2.0.Beta4 Reporter: Radim Vansa Assignee: Adrian Nistor Priority: Blocker Fix For: 5.2.0.Beta5, 5.2.0.Final During a state transfer the entries are sent batched to chunks. However, if all entries are sent in the non-last chunk, the list in entriesBySegment.get(segmentId) is empty. The code for sending last chunks is following: {code:title=OutboundTransferTask.sendEntries(...)} ... if (isLast) { for (int segmentId : segments) { List<InternalCacheEntry> entries = entriesBySegment.get(segmentId); if (entries == null) { chunks.add(new StateChunk(segmentId, InfinispanCollections.<InternalCacheEntry>emptyList(), true)); } } } ... {code} See that the check is {{entries == null}} but not {{entries.isEmpty()}}. This causes to leave some segments unfinished, never finishing the state transfer.
