CommitCommand with replayed PrepareCommand executes rollback and then commit ---------------------------------------------------------------------------- Key: ISPN-3599 URL: https://issues.jboss.org/browse/ISPN-3599 Project: Infinispan Issue Type: Bug Components: State transfer, Transactions Affects Versions: 6.0.0.CR1 Reporter: Radim Vansa Assignee: Pedro Ruivo Priority: Critical Labels: 620, nbst Fix For: 6.0.0.Final During state-transfer in tx cache, the node can receive {{CommitCommand}} from other node. After the node gets transaction data for affected segments, it creates the transaction with {{missingLookedUpEntries=true}} and the {{CommitCommand}} can be executed. In this command's {{perform(...)}} the transaction is *first* marked as completed, then it enters the interceptor chain. There, the {{PrepareCommand}} is created in {{StateTransferInterceptor.visitCommitCommand}} but after this is processed the {{TxInterceptor}} finds out that the transaction is already completed and executes {{RollbackCommand}}, clearing locks etc. Nevertheless, {{StateTransferInterceptor}} executes the initial {{CommitCommand}} afterwards. I suspect that this may be executed without the locks held. Anyway, it is not correct to execute both commit and rollback on the same transaction.
