Subject [jira] Commented: (DERBY-1180) Add vacuous implementations of missing JDBC4 methods
Date Mon, 01 May 2006 13:43:47 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1180?page=comments#action_12377221 ] 

Rick Hillegas commented on DERBY-1180:
--------------------------------------

Committed 4c at subversion revision 398594. Derbyall ran cleanly with 4a before the MessageId
migration and I did not rerun it against 4c. I did rerun the jdbc4 tests against 4c and they
passed.

Unfortunately, this patch introduces another instance of the following build warning which
has been discussed on derby-dev. I believe that Knut Anders has a plan for fixing these:

    [javac] /home/rh161140/derby/mainline/trunk/java/client/org/apache/derby/client/am/LogicalConnection40.java:43:
warn
ing: getTypeMap() in org.apache.derby.client.am.LogicalConnection implements getTypeMap()
in java.sql.Connection; return
 type requires unchecked conversion
    [javac] found   : java.util.Map
    [javac] required: java.util.Map<java.lang.String,java.lang.Class<?>>
    [javac] public class LogicalConnection40

> If you run the VerifySignatures test, you will see a lot of JDBC4 methods which don't
appear in our implementation yet. We need to add vacuous implementations for these methods
which raise SQLFeatureNotSupportedExceptions. Most of these methods won't need any more attention
because they refer to features (like xml and national strings) which we don't support. We
will open additional JIRAs for the methods which need non-vacuous implementations.
