indicates the object is in a state that is known to be acceptable for rollback() to be called. This does not necessarily mean rollback() will succeed or not raise an error, just that there is currently no state detected that indicates rollback() would fail or emit warnings. It also does not mean that there's a transaction in progress, as it is usually safe to call rollback() even if no transaction is present. .. versionadded:: 1.4.28
