From Craig L Russell <craig.russ...@oracle.com>
Subject Minutes: JDO TCK Conference Call Friday, Mar 18, 9 am Pacific Time
Date Fri, 18 Mar 2011 16:43:19 GMT
Attendees: Michelle Caisse, Craig Russell

Agenda:

1. TCK State Transitions test: the way the test creates e.g.  
persistent dirty instances is to get a random persistent instance from  
the database, make it hollow, and then write the field. The  
specification states "A hollow instance transitions to persistent- 
dirty if a change is made to any managed field. " Does this apply if  
the value written is the same as the current value? It's deliberately  
vague. The test could be improved by implementing the  
getPersistentDirtyInstance to write the value of the static field into  
the persistent field instead of the value 23.

There are 50 instances created at the beginning of the test because at  
the time the test is run, you don't know how many instances are  
needed. It depends on the features supported by the iut.

Patches welcome.

2. Ability to mark a class as read-only - https://issues.apache.org/jira/browse/JDO-677

Nothing in the specification calls for writing to the database at the  
time the field is changed, so the checking probably should be done at  
flush/commit, even for datastore transactions.

3. Other issues

Action Items from weeks past:
