Stefania commented on CASSANDRA-13443:
--------------------------------------
Nice catch, +1, provided tests pass.
> V5 protocol flags decoding broken
> ---------------------------------
>
> Key: CASSANDRA-13443
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13443
> Project: Cassandra
> Issue Type: Bug
> Reporter: Robert Stupp
> Assignee: Robert Stupp
> Priority: Minor
> Fix For: 3.11.0, 4.0
>
>
> Since native protocol version 5 we deserialize the flags in
> {{org.apache.cassandra.cql3.QueryOptions.Codec#decode}} as follows:
> {code}
> EnumSet<Flag> flags =
> Flag.deserialize(version.isGreaterOrEqualTo(ProtocolVersion.V5)
> ?
> (int)body.readUnsignedInt()
> : (int)body.readByte());
> {code}
> This works until the highest bit (0x80) is not used. {{readByte}} must be
> changed to {{readUnsignedByte}}.
