Subject [jira] Commented: (DERBY-2532) Client does not return SQLException on XAConnection.getXAResource() on a closed connection, Embedded does
Date Mon, 29 Dec 2008 16:12:47 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12659574#action_12659574

Kristian Waagan commented on DERBY-2532:

Thanks for the patch and the repro, Sabari.

I had a look at the patch and have the following comments;
 a) There is no SQLState associated with the exception being thrown. It would be wise to use
the existing framework to throw an exception with the SQLState specified by SQLState.NO_CURRENT_CONNECTION
(08003). This would also match the embedded driver. You should find examples of this in the
client code, otherwise just ask.

 b) Can you regenerate the patch using 'svn diff'? To make it easier for everyone to apply
the patch, this should be done from the root directory of the source tree (i.e. /my/home/trunk).

 c) The community has agreed to use spaces (4) instead of tabs for indentation.

 d) (Tiny nit) If you want to use the full name for physicalConnection, it makes more sense
to me to use 'super' instead of 'this'. What do you think?

Have you run the regression tests? BTW, they do take some hours to run.
I think the patch will be ready for commit when the mentioned issues have been addressed.
