[jira] [Created] (ZOOKEEPER-1790) Deal with special ObserverId in QuorumCnxManager.receiveConnection

Alexander Shraer created ZOOKEEPER-1790:
-------------------------------------------

             Summary: Deal with special ObserverId in QuorumCnxManager.receiveConnection
                 Key: ZOOKEEPER-1790
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1790
             Project: ZooKeeper
          Issue Type: Bug
          Components: server
    Affects Versions: 3.4.6, 3.5.0
            Reporter: Alexander Shraer
            Assignee: Alexander Shraer
             Fix For: 3.4.6, 3.5.0


QuorumCnxManager.receiveConnection assumes that a negative sid means that this is a 3.5.0 server, which has a different communication protocol. This doesn't account for the fact that ObserverId = -1 is a special id that may be used by observers and is also negative. 

This requires a fix to trunk and a separate fix to 3.4 branch, where this function is different (see ZOOKEEPER-1633)
