I didn't say it was important not to call them; I said it was important to be able to *tell* whether any of the __exit__ methods had actually failed, since this indicates a critical failure of transaction rollback. That is, there was some part of the transaction that could not be rolled back. This is a distinct issue from whatever caused the transaction to be aborted. Also, the __exit__ methods that failed should be logged, but not the __exit__ methods that are simply propagating an exception after performing their rollback behavior. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
