delta/python-packages/qpid-python.git/cpp/src/qpid/cluster/Multicaster.cpp, branch 0.6rc1

Support for restarting a persistent cluster.

2009-11-24T20:07:24+00:00

Option --cluster-size=N: members wait for N members before recovering store.
Stores marked as clean/dirty. Automatically recover from clean store on restart.
Stores marked with UUID to detect errors.

Not yet implemented: consistency checks, manual recovery from all dirty stores.

Removed LatencyTracker from cluster.

Turned out not to be very useful. Better to use profiling tools like systemtap.

Fix cluster race condition with connections closed by broker while in use.

2009-06-30T20:51:38+00:00

If a client is using a connection that is closed at the broker end
because of an error, there is a race condition that allows the
connection to be incorrectly re-created on replica brokers which can
cause those brokers to exit with an error that does not occur on the
directly connected broker.

The fix: explicitly announce new connections, shadow connections are no
longer implicitly created on first use. Make error-check a cluster
control so it can be handled independently of the lifecycle of the
connection where an error initially occured.

Fixed issue with producer flow control in a cluster.

2009-02-24T19:48:54+00:00

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.)
