Subject [jira] Commented: (DERBY-412) Connection toString should show type information and the meaning of the identifier that it prints
Date Thu, 21 Jul 2005 17:45:49 GMT
    [ http://issues.apache.org/jira/browse/DERBY-412?page=comments#action_12316388 ] 

David Van Couvering commented on DERBY-412:
-------------------------------------------

Yes, you are right, the output doesn't match the agreed upon output.  I still have code in
 BrokeredConnection that just prints out the toString() of the connection it wraps. 

Looking at this more closely, however, it is probably useful to know the class of the connection
wrapped by BrokeredConnection.    And if we do that, I think it's important to provide a unique
id for each BrokeredConnection instance

So instead of 

"org.apache.derby.iapi.jdbc.BrokeredConnection30@54322190 (XID = 19), (SESSIONID = 1), (DATABASE
= wombat), (DRDAID = null) "

it should be

"org.apache.derby.iapi.jdbc.BrokeredConnection30@54322190 (ID=22), Wrapped Connection = org.apache.derby.impl.jdbc.EmbedConnection30@25197736
(XID = 19), (SESSIONID = 1), (DATABASE = wombat), (DRDAID = null) "

What do you think?

> After the change for DERBY-243 the  connection toString() output is  an integer which
correspond to SESSIONID.  The output should identify the type and also the meaning of the
identifier that it prints.  Perhaps a format that appends the default toString output with
the sessionid information as it prints in the derby.log would be more informative.

> Ultimately this could be expanded to included other diagnostic information e.g
