Jon Meredith commented on CASSANDRA-16385:
------------------------------------------
I had a think about the patch and wasn't happy with passing the serializer
through everywhere.
I've gone back to updating the Message.java code as I think it is much cleaner.
I've pushed up a branch
[C16385-just-fix-serializer|https://github.com/jonmeredith/cassandra/tree/C16385-just-fix-serializer],
would you mind taking a look at that instead [~ifesdjeen] and [~yifanc]?
Just to note an alternate failed attempts, I tried a version where the
message/deliver calls did the filtering which was fine for pseudo-messaging,
but I got stuck trying to add a handler in the Netty pipeline between the
messaging serialization and framing steps to do the filtering.

> Key: CASSANDRA-16385
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16385
> Project: Cassandra
> Issue Type: Improvement
> Components: Test/dtest/java
> Reporter: Jon Meredith
> Assignee: Jon Meredith
> Priority: Normal
> Fix For: 4.0-beta
>
> Time Spent: 2h
> Remaining Estimate: 0h
>
> When receiving a message, a 4.0 dtest instance reserializes messages to pass
> them through the dtest message filtering.
>
> The 4.0 internode messaging refactor does not expect to have to re-serialize
> response
> messages, so the workaround in CASSANDRA-15946 was just to register the
> ReadResponse serializer for all REQUEST_RESPONSE messages, however request
> response is used for other responses too.
> I'm attaching a patch that demonstrates the issue by adding a simple Paxos
> upgrade test to generate a PrepareResponse message that crashes the
> ReadResponse serializer, then reverts CASSANDRA-15946 and re-users the
> messaging service serialization method that checks the request callback if a
> serializer is not defined.
