* QPID-3858: Updated code to include recent refactoring by Gordon (gsim) - see ↵Kim van der Riet2012-08-271-115/+0
| | | | | | QPID-4178. git-svn-id: https://svn.apache.org/repos/asf/qpid/branches/asyncstore@1377715 13f79535-47bb-0310-9956-ffa450edef68
* QPID-3652: Fix cluster authentication.Alan Conway2011-12-061-0/+2
| | | | | | | | | | | | | | | | | | | Only allow brokers that authenticate as the cluster-username to join a cluster. New broker first connects to a cluster broker authenticates as the cluster-username and sends its CPG member ID to the qpid.cluster-credentials exchange. The cluster broker that subsequently acts as updater verifies that the credentials are valid before connecting to give the update. NOTE 1: If you are using an ACL, the cluster-username must be allowed to publish to the qpid.cluster-credentials exchange. E.g. in your ACL file: acl allow foo@QPID publish exchange name=qpid.cluster-credentials NOTE 2: This changes the cluster initialization protocol, you will need to restart the cluster with all new version brokers. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1210989 13f79535-47bb-0310-9956-ffa450edef68
* QPID-3155: Install module libraries during install-exec phaseAlan Conway2011-03-181-3/+3
| | | | | | | | The C++ automake system has 2 install phases, exec and data. Module libraries are installed incorrectly in the data phase. Fix the makefiles to install them in the exec phase. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1083077 13f79535-47bb-0310-9956-ffa450edef68
* Modified cluster_tests causes broker shut down with invalid-argument error.Alan Conway2010-12-011-1/+3
| | | | | | | | | | Described in https://bugzilla.redhat.com/show_bug.cgi?id=655078. The management agent's deleted-object list was not being replicated to new members joining the cluster, so management generated fewer deleted object notifications on the newer member, causing it to fail with an invalid-argument error. The list is now being replicated correctly. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1041181 13f79535-47bb-0310-9956-ffa450edef68

* Cluster + SecurityMichael Goulish2010-05-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------------- * 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

* Cluster implementation of PeriodicTimer.Alan Conway2010-01-271-0/+2
| | | | | | | | | The cluster implementation multicast periodic-timer controls and executes the task when those controls are delivered, which is in the cluster delivery thread context and so consistent across the cluster. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@903867 13f79535-47bb-0310-9956-ffa450edef68

* Watchdog feature to remove unresponsive cluster nodes.Alan Conway2009-08-101-0/+9
| | | | | | | | | | | | | | | | | In some intstances (e.g. while resolving an error) it's possible for a hung process to hang the entire cluster as they wait for its response. The cluster can handle terminated processes but hung processes present a problem. If the watchdog plugin is loaded and --watchdog-interval is set then the broker forks a child process that runs a very simple watchdog program, and starts a timer in the broker process to signal the watchdog every interval/2 seconds. The watchdog kills its parent if it does not receive a signal for interval seconds. This allows a stuck broker to be removed from the cluster so other cluster members can continue. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@802927 13f79535-47bb-0310-9956-ffa450edef68

* Fix members joining cluster while cluster is handling client errors.Alan Conway2009-07-011-0/+2
| | | | | | | | | | | Previously cluster members could abort if a new member joins while existing members are handling a client error. Now if an update offer arrives while an error is in progress, the offering broker retracts the offer and the newcomer must try again. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@790163 13f79535-47bb-0310-9956-ffa450edef68

* Fixed issue with producer flow control in a cluster.Alan Conway2009-02-241-0/+1
| | | | | | | | | | | | | | | | | | Producer flow control uses a Timer and other clock-based calculations to send flow control commands. These commands are not predictably ordered from the clusters point of view. Added getClusterOrderProxy() to SessionState. In a cluster it returns a proxy that defers sending a command to the client until it is multicast to the cluster. In a stand alone broker it is just the normal proxy. Updated producer flow control to use this proxy. Cluster flow control is turned off in shadow connections. Only the directly connected node does flow control calculations and multicasts the commands to send. All nodes sending of the commands thru SessionState to ensure consistent session state (e.g. command numbering.) git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@747528 13f79535-47bb-0310-9956-ffa450edef68
