[jira] [Commented] (DERBY-5686) multiple intermittent errors in nightly tests during DriverMgrAuthenticationTest test. reason: An SQL data change is not permitted for a read-only connection, user or database.

    [ https://issues.apache.org/jira/browse/DERBY-5686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248651#comment-13248651 ] 

Mike Matrigali commented on DERBY-5686:
---------------------------------------

I spent some time looking at code and the 4/4/2012 error.  I think we are seeing this error intermittently across builds and across jvms.  I had
been interpreting the read only message as something to do with left over files and maybe somehow booting on files being left over and still open
on windows and then derby falling over to readonly.  I see that the DriverMgrAuthenticationTest does as bunch of playing with readonly authentication,
and now am wondering if the setup and/or tearDown routines are somehow getting a left over readonly connection and fail since they need 
write access.

So for this case we have 8 errors and no failures, but each of the errors causes a whole test to just not run so more serious.  
>From this test run we have the following from test run:
(net)jdbcapi.AutoGenJDBC30Test.testUserGivenColumnsNull used 110 ms .
(emb)jdbcapi.DriverMgrAuthenticationTest.testConnectShutdownAuthentication used 12453 ms .
(emb)jdbcapi.DriverMgrAuthenticationTest.testUserFunctions used 1312 ms .
(emb)jdbcapi.DriverMgrAuthenticationTest.testNotFullAccessUsers used 2594 ms .
(emb)jdbcapi.DriverMgrAuthenticationTest.testChangePasswordAndDatabasePropertiesOnly used 1531 ms .

(emb)jdbcapi.DriverMgrAuthenticationTest.testGreekCharacters used 6453 ms .
(emb)jdbcapi.DriverMgrAuthenticationTest.testSystemShutdown used 6968 ms .
(net)jdbcapi.DriverMgrAuthenticationTest.testConnectShutdownAuthentication used 7921 ms .
(net)jdbcapi.DriverMgrAuthenticationTest.testUserFunctions used 2422 ms EEEEEEEE<assertDirectoryDeleted> attempt 1 left 2 files/dirs behind: 0=D:\jartest\JarResults.2012-04-05\ibm16_suites.All\system\singleUse\oneusec0\db.lck 1=D:\jartest\JarResults.2012-04-05\ibm16_suites.All\system\singleUse\oneusec0
.
(emb)jdbcapi.PoolDSAuthenticationTest.testConnectShutdownAuthentication used 19859 ms .

It looks to me like network version of testUserFunctions ran and then we started having problems setting up to run
network testNotFullAccessUsers, and all the rest of the tests left in the suite. 

The end of the testUserFunctions has the following code:
  // reset
  conn1 = openDefaultConnection("dan", ("dan" + PASSWORD_SUFFIX));
  setDatabaseProperty(
      "derby.database.defaultConnectionMode","fullAccess", conn1);
  setDatabaseProperty(
      "derby.connection.requireAuthentication","false", conn1);
  stmt = conn1.createStatement();
  assertUpdateCount(stmt, 0, "drop table APP.t1");
  conn1.commit();
  stmt.close();
  conn1.close();

I am tempted to add a shutdown database here, and reopen default connection to just make sure the next test's setup has the right
connection.  Or could add some retry logic in the setup and teardown - not sure how easy that would be.  But I don't want to mask a real code bug.  I am wondering if there is any sort of connection caching that we are doing that
might not be correctly clearing readonly access?  I seem to remember past bugs where a reused connection would have some left over attribute
sometimes that was not meant to be.  

I read the documentation and it doesn't explicitly say so, but it doesn't say not - so I assume that setting these database properties are
supposed to take effect immediately.  So my assumptions on derby correct behavior would be, but would appreciate opinions of those
with authentication expertise:

1) existing connections don't change their access authentication
2) new connections initiated after the commit of the database properties should pick up new default authentication.

The DatabasePropertyTestSetup.setUp code is going to use a connection that was produced from a getConnection() call which will use
existing test connection if it exists.

Of course this would be all easier to understand if I could reproduce, but I have not been able to in my environment so this is all from 
looking at static test results and the code.  Any opinions on next steps are appreciated.
