* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | - Moved BrokerChannel functionality into Session. - Moved ChannelHandler methods handling into SessionAdapter. - Updated all handlers to use session. (We're still using AMQP channel methods in SessionAdapter) Roles & responsibilities: Session: - represents an _open_ session, may be active or suspended. - ows all session state including handler chains. - attahced to SessionAdapter when active, not when suspended. SessionAdapter: - reprents the association of a channel with a session. - owned by Connection, kept in the session map. - channel open == SessionAdapter.getSessio() != 0 Anything that depends on attachment to a channel, connection or protocol should be in SessionAdpater. Anything that suvives a session suspend belongs in Session. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@571575 13f79535-47bb-0310-9956-ffa450edef68
