Myrna van Lunteren commented on DERBY-3021:
-------------------------------------------

This patch/commit caused a failure in the tinderbox test:

1) test_errorcode(org.apache.derbyTesting.functionTests.tests.lang.ErrorCodeTest)junit.framework.AssertionFailedError:
Missing rows in ResultSet
	at org.apache.derbyTesting.junit.JDBC.assertUnorderedResultSet(JDBC.java:1044)

Is a new bug needed or is this already being worked on?

> The replication slave role includes many tasks:
> * set up a network connection with the master
> * receive chunks of log from the master, and parse these into individual log records
> * append log records to the local log file
> * make sure that the recovery process is not allowed to access the logfile we are currently
writing to
> * etc
> This issue is for adding a controller that will start/stop/initiate all services needed
for the replication slave role.
