Remote commands can access components before they are started ------------------------------------------------------------- Key: ISPN-9127 URL: https://issues.jboss.org/browse/ISPN-9127 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.2.2.Final, 9.3.0.Alpha1 Reporter: Dan Berindei Assignee: Dan Berindei Labels: testsuite_stability Fix For: 9.3.0.Final {{PerCacheInboundInvocationHandler.handle()}} may be called before the component was started, because {{GlobalInboundInvocationHandler}} fetches it from the component registry without any checks. {{CommandsFactoryImpl.initializeReplicableCommand()}} doesn't wait for the components that it injects into remote commands to be started, either. This started causing random test failures in {{ConcurrentStartForkChannelTest}} after ISPN-8515, which moved most initialization work from {{init()}} methods to {{start()}} methods. Because {{StateProviderImpl}} starts after {{StateTransferManagerImpl}}, it's possible for a node to receive a {{StateRequestCommand}} before {{StateProviderImpl}} has initialized: {noformat} 16:15:09,549 TRACE (remote-thread-Test-NodeB-p51957-t2:[org.infinispan.CONFIG]) [StateProviderImpl] Starting outbound transfer to node Test-NodeA for cache null, topology id 2, segments {0-255} 16:15:09,551 WARN (remote-thread-Test-NodeB-p51957-t2:[]) [NonTotalOrderPerCacheInboundInvocationHandler] ISPN000071: Caught exception when handling command StateRequestCommand{cache=org.infinispan.CONFIG, origin=Test-NodeA, type=START_STATE_TRANSFER, topologyId=2, segments={0-255}} java.lang.IllegalArgumentException: chunkSize must be greater than 0 at org.infinispan.statetransfer.OutboundTransferTask.<init>(OutboundTransferTask.java:114) ~[classes/:?] at org.infinispan.statetransfer.StateProviderImpl.startOutboundTransfer(StateProviderImpl.java:273) ~[classes/:?] at org.infinispan.statetransfer.StateRequestCommand.invokeAsync(StateRequestCommand.java:101) ~[classes/:?] at org.infinispan.remoting.inboundhandler.BasePerCacheInboundInvocationHandler.invokeCommand(BasePerCacheInboundInvocationHandler.java:94) ~[classes/:?] {noformat}
