Example 36 with RequestHeader

use of org.apache.zookeeper.proto.RequestHeader in project zookeeper by apache.

the class SessionInvalidationTest method testCreateAfterCloseShouldFail.

/**
 * Test solution for ZOOKEEPER-1208. Verify that operations are not
 * accepted after a close session.
 *
 * We're using our own marshalling here in order to force an operation
 * after the session is closed (ZooKeeper.class will not allow this). Also
 * by filling the pipe with operations it increases the likelyhood that
 * the server will process the create before FinalRequestProcessor
 * removes the session from the tracker.
