[jira] [Created] (RATIS-443) FollowerState.inLogSync can be incorrectly cleared in appendEntriesAsync

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

             Summary: FollowerState.inLogSync can be incorrectly cleared in appendEntriesAsync
                 Key: RATIS-443
                 URL: https://issues.apache.org/jira/browse/RATIS-443
             Project: Ratis
          Issue Type: Bug
          Components: server
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


FollowerState.inLogSync is to indicate that the follower is write log/statemachine data so that it should not time out to start a leader election.  However, it is not working correctly in the async case: suppose there are two or more outstanding appendEntriesAsync calls, the first completed call will clear inLogSync even if the other calls are still in progress.
