Make multiplex server invoker more robust
-----------------------------------------
Key: JBREM-729
URL: http://jira.jboss.com/jira/browse/JBREM-729
Project: JBoss Remoting
Issue Type: Task
Security Level: Public (Everyone can see)
Affects Versions: 2.4.0.Beta1 (Pinto)
Reporter: Ron Sigal
Assigned To: Ron Sigal
Fix For: 2.4.0.Beta1 (Pinto)
Claudia Richter has reported some problems using Remoting JNDI detection with multiplex transport. If the JNDI heartbeat is looking for an old socket invoker at an address and port where a multiplex invoker currently runs, the multiplex invoker can get hung up trying to process in invocation intended for the socket invoker. It should be able to tolerate unexpected inputs. In particular, MultiplexServerInvoker should set a timeout on the MasterServerSocket so that it doesn't get hung up in accept().

[JBoss JIRA] Created: (JBAS-4176) Error in delist masks the real error creating the connection handle in BaseConnectionManager2

Error in delist masks the real error creating the connection handle in BaseConnectionManager2
---------------------------------------------------------------------------------------------
Key: JBAS-4176
URL: http://jira.jboss.com/jira/browse/JBAS-4176
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: JCA service
Reporter: Adrian Brock
Assigned To: Weston Price
Fix For: JBossAS-4.2.0.CR1
There is a problem with the error reporting in BaseConnectionManager2.allocationConnection().
When it can't get a connection handle, it invokes managedConnectionDisconnected() to
make sure any work already done is undone, e.g. delist the resource and return to the pool.
The problem is that an error thrown from managedConnectionDisconnected()
will be given to the user rather than the original error thrown when getting the handle.
// Ask the managed connection for a connection
Object connection = null;
try
{
connection = cl.getManagedConnection().getConnection(subject, cri);
}
catch (Throwable t)
{
// HERE: Error from this method
managedConnectionDisconnected(cl);
// Means this original error is not thrown
JBossResourceException.rethrowAsResourceException(
"Unchecked throwable in ManagedConnection.getConnection() cl=" + cl, t);
}
In fact, if we do get an error asking for a handle, we should probably just quietly (no logging above DEBUG)
destroy the connection and then rethrow the original error.
i.e.
catch (Throwable t)
{
// HERE: Destroy the connection
returnManagedConnection(cl, true);
JBossResourceException.rethrowAsResourceException(
"Unchecked throwable in ManagedConnection.getConnection() cl=" + cl, t);
}
