Subject [jira] Created: (QPID-1488) QueuePolicy serialization fix for cluster braindump.
Date Wed, 26 Nov 2008 20:22:44 GMT
QueuePolicy serialization fix for cluster braindump.
----------------------------------------------------

                 Key: QPID-1488
                 URL: https://issues.apache.org/jira/browse/QPID-1488
             Project: Qpid
          Issue Type: Improvement
          Components: C++ Broker
         Environment: tested on F9
            Reporter: michael j. goulish
            Priority: Blocker


In cluster braindump (when a new member is being added to a cluster) the QueuePolicy is not
being serialized out as part of the brain dump.  As a result the newbie cluster can get a
mistaken idea of the queue size (in bytes).  
After many dequeues, the size can go negative, but since the queue size is an unsigned number
it wraps around and look like a large positive.  Which sets off the flow-to-disk code, because
it thinks that the queue has gotten too large.

This fix just adds a little serialization of the QueuePolicy on to the end of the serialization
of the Queue.
