-------------------------------------------
Summary: Restore check for consistent native protocol versions for
connection
Key: CASSANDRA-16374
URL: https://issues.apache.org/jira/browse/CASSANDRA-16374
Project: Cassandra
Issue Type: Bug
Components: Messaging/Client
Reporter: Sam Tunnicliffe
In protocol v4 and earlier, the frame header is checked during deserialization
to ensure that the version matches the one negotiated for the connection.
The original intention was to remove this version id from the frame (renamed to
envelope in v5) header. However, there is value in keeping this check as well
as the the one for the beta flag, so it remains in the frame/envelope format.
The validation itself however, was removed by some refactoring as part of
CASSANDRA-15299 and should be added back for all protocol versions before
finalizing v5 and cutting a release candidate. The text detailing its removal
also remains in the proposed spec update attached to CASSANDRA-14688, which
also needs to be updated.
