From Craig L Russell <Craig.Russ...@Sun.COM>
Subject Minutes: JDO TCK Conference Call Friday, Aug 15, 9 am PDT
Date Fri, 15 Aug 2008 17:11:44 GMT
Attendees: Richard Schilling, Michelle Caisse, Craig Russell


1. Control over transaction isolation level. There does not appear to  
be agreement over whether it is possible to completely define  
transactional behavior of a jdo implementation. While it is possible  
for the implementation to use a user-specified transaction isolation  
level for the underlying datastore, it's still not possible to mandate  
the behavior associated with, e.g., read-uncommitted.

2. Other issues

Richard downloaded Grails and was impressed. The separation of  
persistence specification from the actual class was not so great, but  
the overall experience was excellent.

Release schedule for JDO 2.2. Looks like most of the issues can be  
done by end of September, so let's try for at least a preview by then.  
The last release was done in March, so six month schedule would have a  
new release in September. There are some JCP gating processes so we  
should try to close on the specification issues soon.

Re: https://issues.apache.org/jira/browse/JDO-556 assigned temporarily  
to Craig to add a requirement for a no-args constructor for PMF as a  
prerequisite for ServiceLoader.

Action Items from weeks past:

[Feb 1 2008] AI  Matthew see what would be needed to update the PMF  
contract to support  ServiceLoader.

[Nov 30 2007] AI Christiaan propose more details on Update/copy by  
query for post-JDO 2.1.

[May 25 2007]  AI everyone download the Grails demo from grails.org   
and check it out. Also look at Grails/Groovy ExpandoMetaClass that   
has the magic to avoid reflection and enhancement.

[May 25 2007] AI Matthew Adams prepare a proposal with just the basics  
of schema synchronization with jdo and orm metadata.

[Aug 11 2006] AI Craig propose some semantics for behavior if user  
tries to add to a list where the ordering element is incorrect.

[Sep 2 2005] AI: To recruit members:  Articles on  TheServerSide  
directing attention to the site. T-shirts.  AI:   Craig write a  
ServerSide article.
