[appengine-java] Persisting and deleting objects using same PersistanceManager
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?
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);
newProperties.put(javax.jdo.option.RetainValues, true);
newProperties.put(datanucleus.appengine.autoCreateDatastoreTxns,
true);
newProperties.put(datanucleus.appengine.autoCreateDatastoreTxns,
true);
PersistenceManagerFactory pmf = JDOHelper
.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());
try {
JDOMockBasicObject l = (JDOMockBasicObject)
pm.getObjectById(
JDOMockBasicObject.class, id);
fail(not supposed to get here);
} catch (JDOObjectNotFoundException e) {
}
}
// Mock class:
import javax.jdo.annotations.IdGeneratorStrategy;

public class JDOMockBasicObject {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
public Long getId(){
return key.getId();
}
public Key getKey(){
