------------------------------
Summary: Add test to WANRollingUpgradeDUnitTest to detect
serialization changes to GatewaySenderEventImpl
Key: GEODE-4886
URL: https://issues.apache.org/jira/browse/GEODE-4886
Project: Geode
Issue Type: Bug
Components: wan
Reporter: nabarun
GatewaySenderEventImpl types are added to the queue. When rolling upgrade
occurs, these events are gii'd/distributed as region data/ not as messages.
That means the toData_version and fromData_version code does not get executed.
We should have a test (or two) in WANRollingUpgradeDUnitTest that can detect
this scenario.
I believe the scenario is trying to get a new sender to deserialize an old
event:
1.create a sender, pause
2.do puts, build up the queue.
3. roll to current
4.start senders on current
The second scenario is to get new events to flow back to the old member and
have the old member try to deserialize the new event
1.)create a sender, pause
2.)do puts, build up the queue.
3.) roll to current
4.) do additional puts that get queued in the new member with a redundant copy
on the old member
5.) remove the new member
6.) start sender on old member
