The built-in ``@contextmanager`` utility does not work well when wrapping other contexts, as the traceback is wrong when the wrapped context raises. This solves this problem and can be used instead of ``@contextmanager`` in this example:: @contextmanager def connection_or_default_connection(connection=None): if connection: # user already has a connection, shouldn't close # after use yield connection else: # must've new connection, and also close the connection # after the block returns with create_new_connection() as connection: yield connection This wrapper can be used instead for the above like this:: def connection_or_default_connection(connection=None): return FallbackContext(connection, create_new_connection) cOs"||_||_||_||_d|_dSr)providedfallbackfb_args fb_kwargs_context)r rrr r!r r r rJs  zFallbackContext.__init__cCs2|jdur|jS|j|ji|j}|_|Sr)rrr r! __enter__r")r contextr r r r#Qs zFallbackContext.__enter__cGs|jdur |jj|SdSr)r"__exit__)r exc_infor r r r%Ys  zFallbackContext.__exit__N)rrrrrr#r%r r r r r.s  rc@s4eZdZdZd ddZddZd ddZd d ZdS) raAttribute -> dict key descriptor.
