Can still retrieve a P_DELETED object via getObjectById when deleted non-transactional

[GoogleCodeExporter]

Hi, 
I have this test (I am creating object, persist it and trying to 
remove it) and it is failing on "fail("not supposed to get here");" 
line. Is it bug in GAE JDO or JDO is supposed to work in this way? 

Lines from test:

private final LocalServiceTestHelper helper = new 
LocalServiceTestHelper( 
                        new LocalDatastoreServiceTestConfig()); 
@Before 
        public void setUp() { 
                helper.setUp(); 
        } 
        @After 
        public void tearDown() { 
                helper.tearDown(); 
        } 
@Test 
        public void testBasicDelete() { 
                Properties newProperties = new Properties(); 
                newProperties 
                                .put("javax.jdo.PersistenceManagerFactoryClass", 
                                                "org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory" ); 
                newProperties.put("javax.jdo.option.ConnectionURL", "appengine"); 
                newProperties.put("javax.jdo.option.NontransactionalRead", "true"); 
                newProperties.put("javax.jdo.option.NontransactionalWrite", "true");

                                .getPersistenceManagerFactory(newProperties); 
                PersistenceManager pm = pmf.getPersistenceManager(); 
                JDOMockBasicObject m = new JDOMockBasicObject(); 
                pm.makePersistent(m); 
                long id = m.getId(); 
                assertTrue(id > 0); 
                JDOMockBasicObject k = (JDOMockBasicObject) pm.getObjectById( 
                                JDOMockBasicObject.class, id); 
                pm.deletePersistent(k); 
                Query query = pm.newQuery(JDOMockBasicObject.class); 
                query.setFilter("key == k"); 
                query.declareParameters("com.google.appengine.api.datastore.Key k"); 
                query.deletePersistentAll(k.getKey());

                        fail("not supposed to get here"); 
                } catch (JDOObjectNotFoundException e) { 
                }

And if you call pm.evictAll() after the deletePersistent() then it isn't in the 
L1 cache (in state P_DELETED), and consequently you don't find it. Ample 
workarounds

• Changed title: Can still retrieve a P_DELETED object via getObjectById when deleted non-transactional

[GoogleCodeExporter]

Actually, when SVN trunk is run with current DataNucleus any nontx deleted 
objects are no longer in the L1 cache, so no object is found from getObjectById
