Solve the following python programming problem given the following code:
def commit_on_success(using = None) : 
    '
    This decorator activates commit on response. This way, if the view function
    runs successfully, a commit is made.
if the viewfunc produces an exception,
    a rollback is made. This is one of the most common ways to do transaction
    control in Web apps.
    ' 
    warnings.warn ('commit_on_success is deprecated in favor of atomic.', PendingDeprecationWarning, stacklevel = 2) 
    def entering(using) : 
        enter_transaction_management (using = using) 
def exiting(exc_type, using) : 
        try : 
            if (exc_type is not None) : 
                if is_dirty (using = using) : 
                    rollback (using = using) 
else : 
                if is_dirty (using = using) : 
                    try : 
                        commit (using = using) 
except : 
                        rollback (using = using) 
                        raise 
finally : 
            leave_transaction_management (using = using) 
return _transaction_func (entering, using, using) 

    
    

    Fix the buggy line: return _transaction_func (entering, using, using)
