Persistent objects lose _p_uid attribute after commit #39

Closed michwill closed 8 years ago

michwill commented 8 years ago

When observed:

Get a list of objects: list(db[Model].query(...))
Do transaction.commit(), clear memory cache and gc.collect()
Bang. All objects without _p_uid o_O

This is observed only when actual changes to objects are committed. Example addition to test_db.py::test_all_uid which fails:

    objs = list(db[Page].all())
    obj = objs[0]
    obj.title += " temp"
    transaction.commit()
    for obj in objs:
        assert hasattr(obj, "_p_uid")

Oops, the fix fails in python3 (setattr falls into infinite recursion?)
