From Craig L Russell <Craig.Russ...@Sun.COM>
Subject Minutes: JDO TCK Conference Call Friday, Feb 13, 9 am PST
Date Fri, 13 Feb 2009 18:07:35 GMT
Attendees: Matthew Adams, Michael Bouschen, Michelle Caisse, Craig  


1.  Enhancer specification proposal. 1. -ecp is good but inconsistent  
in the text. 2. Should describe options in the same order as listed in  
both places. AI Craig write an enhancer Main class and upload to  
JIRA.  Feedback needed from other experts.

2. Other issues

Query.cancel changes have been checked in. Don't appear to be any  
issues. AI Craig update the spec and make clear the relationship  
between Query.cancel and multithreading (multithreaded flag doesn't  
need to be true to perform a Query.cancel).

How might an application dynamically tune itself by tracking field  
access by use-case? Need a few things: 1. identify which use case  
you're in; might have to analyze the stack frames at the time a use- 
case was needed, e.g. whenever an instance needed to be fetched or a  
query executed 2. associate a use case with a fetch plan 3. modify the  
fetch plan based on runtime experience, e.g. which fields were  
accessed by the use-case. AI Matthew discuss on email.

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.
