Subject [jira] [Created] (ZOOKEEPER-2420) Autopurge deletes log file prior to oldest retained snapshot even though restore would need it

----------------------------------

             Summary: Autopurge deletes log file prior to oldest retained snapshot even though
restore would need it
                 Key: ZOOKEEPER-2420
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2420
             Project: ZooKeeper
          Issue Type: Bug
          Components: server
            Reporter: Ed Rowe


Autopurge retains all log files whose zxid are >= the zxid of the oldest log file that
it is going to retain (in PurgeTxnLog retainNRecentSnapshots()). Given that loading the database
from snapshots/logs will start with the log file _prior_ to the snapshot's zxid, autopurge
should retain this log file as well unless it verifies that it contains no zxids beyond what
the snapshot contains.
