[ http://issues.apache.org/jira/browse/DERBY-1015?page=comments#action_12420677 ]
David Van Couvering commented on DERBY-1015: -------------------------------------------- I looked at the patches, and they look quite good, very simple and direct, and creating what I think is a very useful and important abstraction between the network server and the engine. I think it would be good to complete the abstraction and not depend directly on any engine classes, including EmbedSQLException, but I would argue that should be a separate JIRA. I'll work on getting this committed. > Define interface between network server and engine through Java interfaces. > --------------------------------------------------------------------------- > > Key: DERBY-1015 > URL: http://issues.apache.org/jira/browse/DERBY-1015 > Project: Derby > Type: Improvement > Components: JDBC > Reporter: Daniel John Debrunner > Assignee: Daniel John Debrunner > Fix For: 10.2.0.0 > Attachments: Derby1015.p2.diff.txt, derby1015.diff.txt, > derby1015.p2.stat.txt, derby1015.stat.txt > > API between the network server and engine is not well defined, leading to > inconsistent & multiple ways of handling the different objects returned, such > as reflection, explicit casting etc. This in turn has lead to bugs such as > DERBY-966 . DERBY-1005, and DERBY-1006, and access to underlying objects by > the application that should be hidden. > Define interfaces, such as EngineConnection, that both EmbedConnection and > BrokeredConnection implement. Thus the network server can rely on the fact > that any connection it obtains will implement EngineConnection, and call the > required methods through that interface. > Most likely will need EngineConnection, EnginePreparedStatement and > EngineResultSet.. These interfaces would be internal to derby and not exposed > to applications. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
