New Revision: 557788
URL: http://svn.apache.org/viewvc?view=rev&rev=557788
Log:
* Summary:
- Connect cluster handlers into broker handler chains.
- Progress on wiring replication.
* src/tests/cluster.mk: Temporarily disabled Cluster test.
* src/tests/Cluster.h, cpp, Cluster_child.cpp: Updated to use UUIDs.
* src/qpidd.cpp:
- Load optional libs (cluster)
- Include plugin config in options.parse.
* src/qpid/cluster/SessionManager.h:
- Create sessions, update handler chains (as HandlerUpdater)
- Handle frames from cluster.
* src/qpid/cluster/ClusterPlugin.h, .cpp:
- renamed from ClusterPluginProvider
- Create and connect Cluster and SessionManager.
- Register SessionManager as HandlerUpdater.
* src/qpid/cluster/Cluster.h, .cpp: Refactor as SessionFrameHandler.
* src/qpid/broker/Connection.cpp: Apply HandlerUpdaters.
* src/qpid/broker/Broker.h, .cpp:
- Initialize plugins
- Apply HandlerUpdaters
* src/qpid/Plugin.h, .cpp: Simplified plugin framework.
