From Craig L Russell <Craig.Russ...@Sun.COM>
Subject Minutes: JDO TCK Conference Call Friday, Dec 4, 9 am PDT
Date Fri, 05 Dec 2008 18:09:43 GMT
Attendees: Michael Bouschen, Michelle Caisse, Craig Russell


1. (JDO-615) MetaData specification API: Discussion in the JIRA is on  
factory methods for single-valued properties; using bean property  
patterns for factory methods; setting parent automatically versus  
explicitly; provide methods for modifying the structure (remove  
methods, unset methods); should factory methods for items that have  
required attributes like name also require the attribute as a  
parameter; should boolean properties strictly follow the bean pattern.  
AI Michael add comments to JIRA.

2. (JDO-591) Enhancer Invocation API: JDO RI now implements the new  
API; this JIRA should be closed and new JIRAs opened for follow-on  
work. For example, adding a utility Main class in javax.jdo to parse  
command line and call the enhancer; adding plugins for eclipse, maven,  
netbeans, etc.

3. (JDO-617) JDOQL : Bulk Update and Delete Operations: It would be  
nice for this feature to have some justification. AI Craig update JIRA  
with more specific comments.

4. (JDO-620) datastore identifier needed for improving replication of  
objects: This needs some more discussion to see if JDO is an  
appropriate technology for low-level operations like replication.

5. (JDO-619) API required for enabling/disabling FOR UPDATE locking  
for SELECTs: It seems useful for real applications. Maybe we can  
augment the fetch plan and/or metadata. If set in metadata, and not  
overridden at runtime, all getObejctById, navigation, and query would  
use the FOR UPDATE. If set in fetch plan, only operations that use the  
fetch plan would be affected. AI discuss further on JIRA.

6. Other issues: none

Action Items from weeks past:

[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.

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