Solve the following python programming problem given the following code:
def commit_on_success_unless_managed(using = None, savepoint = False) : 
    "
    Transitory API to preserve backwards-compatibility while refactoring.

    Once the legacy transaction management is fully deprecated, this should
    simply be replaced by atomic. Until then, it's necessary to guarantee that
    a commit occurs on exit, which atomic doesn't do when it's nested.

    Unlike atomic, savepoint defaults to False because that's closer to the
    legacy behavior.

    connection = get_connection (using) 
    if (connection.get_autocommit () or connection.in_atomic_block) : 
        return atomic (using, savepoint) 
else : 
        def entering(using) :

def exiting(exc_type, using) : 
            set_dirty (using = using)
