Review request for geode, Alexander Murmann, Barry Oglesby, Galen O'Sullivan,
Hitesh Khamesra, and Brian Rowe.
Changes
-------
adding a second current-version server to the test, as suggested by Galen and
Brian
Bugs: GEODE-3153
https://issues.apache.org/jira/browse/GEODE-3153
Repository: geode
Description
-------
Another problem was found in backward-compatibility testing. If a 1.0.0 client
was receiving subscription events generated by a 1.0.0 peer "feeder" member and
the events were routed through a 1.0.0 server the client might see duplicate
events when the server is stopped and the client fails over to a 1.2.0 server
holding its redundant subscription queue. This is especially possible if a
large "ack" period is established in the client.
The problem stems from the EventID deserialization/reserialization of the
memberID bytes when sending to a 1.0 client. It was deserializing using
Version.CURRENT, which ignores the UUID bytes in the serialized ID. Then it
serialized the identifier using the client's version, which includes the UUID
bytes but which are zero due to the version used in deserialization.
