Attendees: Michael Bouschen, Tilmann Zäschke, Craig Russell Agenda:
1. EMail "A new general method to update object databases / Should it be included in Java Data Objects, JDO ?” There has been no more discussion; it’s not clear that the author understands JDO, especially how JDO manages objects in memory organized in a graph. 2. Discussion "EmbeddedPCMapping cannot be cast to PersistableMapping” Probably not related to optional. Seems to be a bug in datanucleus. AI Michael update query test case to specifically test for “double NOT” and file a bug. Possible test scenarios: !(field != value) !(field != null) !!(field != value) !!(field != null) !!!(field != value) !!!(field != null) 3. New patch JDO-751 "Support for Java8 Optional" https://issues.apache.org/jira/browse/JDO-751 Reviewed Tilmann’s message from June 1: query #2= "optionalPC.get().id == " + DUMMY_ID returns the dummy object instead of the object that references the dummy object; probably a bug in datanucleus query: "optionalPC == null” returns objects in the datastore that either have optionalPC empty or null; datanucleus stores empty objects as null in the datastore; ok behavior query "!(optionalPC == null)” returns objects in the datastore that have optionalPC not null but not objects where optionalPC empty; ok behavior because datanucleus stores empty objects as null do we really need to have jdoql implement optional.orElse? the test case for orElse doesn’t make a strong case for it. The use of orElse in Java is not in question, but we should try to find a good use-case for it in jdoql. Need proposed specification changes. AI Craig 4.
