Robert Stupp created CASSANDRA-13443:
----------------------------------------
Summary: 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
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}}.
