Bug in WriteLock recipe implementation?

                 Key: ZOOKEEPER-645
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-645
             Project: Zookeeper
          Issue Type: Bug
    Affects Versions: 3.2.2
         Environment: 3.2.2 java 1.6.0_12
            Reporter: Jaakko Laine
            Priority: Minor

Not sure, but there seem to be two issues in the example WriteLock:

(1) ZNodeName is sorted according to session ID first, and then according to 
znode sequence number. This might cause starvation as lower session IDs always 
get priority. WriteLock is not thread-safe in the first place, so having 
session ID involved in compare operation does not seem to make sense.

(2) if findPrefixInChildren finds previous ID, it should add dir in front of 
the ID
