Phillip J. Eby	ccc7bb4ef2	More extensive comment on __exit__ handling, per Guido's request.	2006-03-25 04:32:12 +00:00
Phillip J. Eby	6edd258608	Fix a problem with @contextmanager not detecting a broken generator ... that yields after a throw(). Make @contextmanager not reraise exceptions, but return a false value in that case instead. Add test cases for both behaviors.	2006-03-25 00:28:24 +00:00
Guido van Rossum	f669436189	Um, I thought I'd already checked this in. ... Anyway, this is the changes to the with-statement so that __exit__ must return a true value in order for a pending exception to be ignored. The PEP (343) is already updated.	2006-03-10 02:28:35 +00:00
Guido van Rossum	a9f068726f	Fix a bug in nested() - if one of the sub-context-managers swallows the ... exception, it should not be propagated up. With unit tests.	2006-03-01 17:10:01 +00:00
Guido van Rossum	1a5e21e033	Updates to the with-statement: ... - New semantics for __exit__() -- it must re-raise the exception if type is not None; the with-statement itself doesn't do this. (See the updated PEP for motivation.) - Added context managers to: - file - thread.LockType - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore} - decimal.Context - Added contextlib.py, which defines @contextmanager, nested(), closing(). - Unit tests all around; bot no docs yet.	2006-02-28 21:57:43 +00:00
