[jboss-remoting-issues] [JBoss JIRA] Closed: (JBREM-956) Make LeasePinger timeout separately configurable

Make LeasePinger timeout separately configurable ------------------------------------------------ Key: JBREM-956 URL: http://jira.jboss.com/jira/browse/JBREM-956 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Components: transport Affects Versions: 2.2.2.SP2, 2.2.2.SP1, 2.2.2.GA, 2.2.1.GA, 2.2.0.GA (Bluto), 2.4.0.CR1 (Pinto), 2.4.0.Beta2 (Pinto), 2.2.2.SP5, 2.4.0.Beta1 (Pinto), 2.2.2.SP4, 2.2.2.GA_CP03, 2.2.2.GA_CP02, 2.2.2.GA_CP01, 2.2.0.SP4, 2.2.0.SP3, 2.2.0.SP2, 2.2.0.SP1, 2.0.0.GA (Boon) Environment: JBoss 4.2.1, Windows XP SP2, Redhat Enterprise Linux 3.0 Reporter: Guy Nir Assigned To: Ron Sigal Fix For: 2.4.0.CR2 When a client and server resides on different machines and server suddenly disconnected from the network (i.e.: cable disconnected or host is cord-reseted/power down brutely) the client side does not recognize this situation and remains blocking. The main reason for this behavior is that TCP does not provide direct indication that a connection is dropped (unless a probe such as KeepAlive is activated). The LeasePinger class should resolve this issue, however, the invocation of sendClientPing() method remains blocking as well. A different shorter timeout should be placed for sendClientPing() (perhaps timeout-per-invocation approach ?). For example, instead of using the following implementation (taken from sendClientPing) : Map clientsClone = new ConcurrentHashMap(clients); Map requestClients = new ConcurrentHashMap(); requestClients.put(ClientHolder.CLIENT_HOLDER_KEY, clientsClone); InvocationRequest ir = new InvocationRequest(invokerSessionID, null, "$PING$", requestClients, null, null); invoker.invoke(ir); It is possible to use: int clientPingLeaseTimeout = ......; Map clientsClone = new ConcurrentHashMap(clients); Map requestClients = new ConcurrentHashMap(); requestClients.put(ClientHolder.CLIENT_HOLDER_KEY, clientsClone); requestClients.put(ServerInvoker.TIMEOUT, clientPingLeaseTimeout); InvocationRequest ir = new InvocationRequest(invokerSessionID, null, "$PING$", requestClients, null, null); invoker.invoke(ir);
