Dag H. Wanvik commented on DERBY-4186:
--------------------------------------
Thanks for noticing the duplicate, Kathey. I closed DERBY-3915 as dup, since I
already had started making comments on this issue.
> After failover, test fails when it succeeds in connecting early to failed

> Key: DERBY-4186
> URL: https://issues.apache.org/jira/browse/DERBY-4186
> Project: Derby
> Issue Type: Bug
> Components: Replication, Test
> Affects Versions: 10.6.0.0
> Reporter: Dag H. Wanvik

> Occasionally I see this error in ReplicationRun_Local_3_p3:
> 1)
> testReplication_Local_3_p3_StateNegativeTests(org.apache.derbyTesting.functionTests.tests.replicationTests.ReplicationRun_Local_3_p3)junit.framework.AssertionFailedError:

> In the code, after a stopMaster is given to the master (should lead to
> fail-over),
> the tests expects to see CANNOT_CONNECT_TO_DB_IN_SLAVE_MODE (08004.C.7),
> which will only succeed if
> the tests gets to try to connect before the failover has started. This seems
> wrong. If the failover has completed, it should expect a successful
> connect (which boots the database, btw, since its shut down after auccessful
> failover).
> Quote from code:
> waitForSQLState("08004", 100L, 20, // 08004.C.7 -
> CANNOT_CONNECT_TO_DB_IN_SLAVE_MODE
> slaveDatabasePath + FS + slaveDbSubPath + FS + replicatedDb,
> slaveServerHost, slaveServerPort); // _failOver above fails...
> There is a race between the failover on the slave and the test here I think.
