Transaction sometimes does not work #22

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

The following code sometimes fails.

Entity entity = new Entity("Test", "k");
Datastore.put(entity);

Transaction tx = Datastore.beginTransaction();
entity.setProperty("p", 0);
Datastore.put(tx, entity);
Datastore.rollback(tx);

if (Datastore.get(entity.getKey()).getProperty("p") != null) {
    throw new IllegalStateException();
}

The cause is DatastoreUtil#createPutRequest().
DatastoreUtil#createPutRequest() assumes that transaction handle is
positive. But in fact, there are the cases transaction handle is negative.
