[infinispan-issues] [JBoss JIRA] (ISPN-2814) RpcManager doesn't return values properly

RpcManager doesn't return values properly ----------------------------------------- Key: ISPN-2814 URL: https://issues.jboss.org/browse/ISPN-2814 Project: Infinispan Issue Type: Bug Components: RPC Affects Versions: 5.1.5.FINAL Reporter: William Burns Assignee: Adrian Nistor Fix For: 5.3.0.Final We currently use some custom commands with Infinispan. We have since moved over to wanting to use a custom command with a return value for the response. We have tried using the various methods on the RpcManager and have found a few issues. 1. Map<Address, Response> invokeRemotely(Collection<Address> recipients, ReplicableCommand rpc, boolean sync, boolean usePriorityQueue) throws RpcException; This method always returns a null for cluster responses. This is a simple issue that can be solved with the following diff {code} diff --git a/core/src/main/java/org/infinispan/commands/remote/SingleRpcCommand. index bf369bc..79bc02e 100644 --- a/core/src/main/java/org/infinispan/commands/remote/SingleRpcCommand.java +++ b/core/src/main/java/org/infinispan/commands/remote/SingleRpcCommand.java @@ -107,6 +107,6 @@ public ReplicableCommand getCommand() { @Override public boolean isReturnValueExpected() { - return false; + return command.isReturnValueExpected(); } } {code} The SingleRpcCommand wraps the given command always forcing the return value expectation to be false. 2. Map<Address, Response> invokeRemotely(Collection<Address> recipients, ReplicableCommand rpcCommand, ResponseMode mode, long timeout); This method doesn't wrap the return value in a Response thus causing a ClassCastException when the client node gets the response back. I haven't looked into detail with this one yet. If needed I can send a sample project that shows the behavior.
