Subject [jira] Commented: (DERBY-3037) Language ResultSet.finish() is called even when the ResultSet is going to be re-used.
Date Thu, 06 Dec 2007 19:49:43 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12549155

Mamta A. Satoor commented on DERBY-3037:

I committed a change(601830) into trunk with following commit comments


This commit makes sure that EmbeddedResultSet.close() calls Language Resultset.close rather
than Language 
Resultset.finish. This change caused few tests to fail. The tests had runtime statistics on
but the code to dump 
the runtime statistics was in Language Resutlset.finish and not in Language Resultset.close.
To fix this, I have 
moved the code to dump runtime statistics from Language Resutlset.finish into Lanugage ResultSet.close
This has 
fixed the test failures. 

As for the 2nd part of this jira entry which is to have activation.close() call Language Resultset.finish().
already happens in impl.sql.execute.BaseActivation.close() and hence no work was needed for
the 2nd part.

Will merge this change into 10.3 codeline soon.

> DERBY-827 (correctly) changed the lifetime of the language ResultSet tree to be the lifetime
of the activation, but did not fix up the correct calls to ResultSet.close() and ResultSet.finish().
> A language ResultSet's lifetime should be driven by the activation, so activation.close()
should call finish() on its ResultSet.
> EmbedResultSet should call close on its language ResultSet (theResults field) when the
JDBC ResultSet is closed, it should not be calling finish() on its ResultSet.
> See comments in DERBY-827 for some more details and issues.
