* Cluster handle connection-negotiation phase in local broker.Alan Conway2010-06-081-9/+4
| | | | | | | | | | | | | | | | | The connection negotiation phase up to the "open" or "open-ok" frame establishes whether/what encryption to use for the rest of the connection. With this patch a cluster broker completes the initial negotiation with its local clients and only then begins multicasting to other brokers. The local broker decrypts if necessary and multicasts in the clear. This replaces a problematic locking scheme that was formerly in place which caused deadlocks. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@952692 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------------- * initial observation of a problem was a 2% failure rate in perftests of 20,000 messages against a cluster with security enabled. Problem was occasional receit of encrypted frames before the security codec had been enabled. This is fixed with locking in cluster code (no new locks in broker code) and a callback that is fired by broker::ConnectionHandler::Handler to tell the cluster code when the opening handshake has finished. This was never a problem in the non-clustered broker before because everything happened in a single thread. * the brokers that "shadow" the connection must not have null authenticators rather than real ones, so that they go through all the motions but don't do anythig. Only the directly-connected broker can perform the security handshake. * once the directly-connected broker receives the real user ID from its callback, it mcasts that ID to all other brokers. Otherwise the shadowing brokers will al think that the user ID is "anonymous". Check this by doing a substantial perftest, and using qpid-stat -c localhost:PORT to confirm that the brokers all have the same userID for the same connection. * the user ID, negotiated during the Sasl security startup, is communicated from the directly connected broker to all other cluster brokers. * If security is *not* being used, then this code should *not* tell the brokers anything about the userID -- or it will step on the value that is being set by other code pathways. * test program at cpp/src/tests/cluster_authentication_soak is not yet fully automated -- run it with something like "sudo ./cluster_authentication_soak 500" git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@944158 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | | | | | 1) Durability for federation links (broker-to-broker connections) 2) Improved handling of federation links: a) Links can be created even if the remote broker is not reachable b) If links are lost, re-establishment will occur using an exponential back-off algorithm 3) Durability of exchanges is now viewable through management 4) ManagementAgent API has been moved to an interface class to reduce coupling between the broker and manageable plug-ins. 5) General configuration storage capability has been added to the store/recover interface. This is used for federation links. 6) Management object-ids for durable objects are now themselves durable.
