* bpo-44471: Change error type for bad objects in ExitStack.enter_context() ↵Serhiy Storchaka2021-06-291-1/+22
| | | | | | | | | (GH-26820) A TypeError is now raised instead of an AttributeError in ExitStack.enter_context() and AsyncExitStack.enter_async_context() for objects which do not support the context manager or asynchronous context manager protocols correspondingly.
* bpo-12022: Change error type for bad objects in "with" and "async with" ↵Serhiy Storchaka2021-06-291-2/+2
| | | | | | | | | (GH-26809) A TypeError is now raised instead of an AttributeError in "with" and "async with" statements for objects which do not support the context manager or asynchronous context manager protocols correspondingly.

* bpo-36492: Deprecate passing some arguments as keyword arguments. (GH-12637)Serhiy Storchaka2019-04-011-0/+11
| | | | | | | | | | | | | | | | | | | | | | Deprecated passing the following arguments as keyword arguments: - "func" in functools.partialmethod(), weakref.finalize(), profile.Profile.runcall(), cProfile.Profile.runcall(), bdb.Bdb.runcall(), trace.Trace.runfunc() and curses.wrapper(). - "function" in unittest.addModuleCleanup() and unittest.TestCase.addCleanup(). - "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor and concurrent.futures.ProcessPoolExecutor. - "callback" in contextlib.ExitStack.callback(), contextlib.AsyncExitStack.callback() and contextlib.AsyncExitStack.push_async_callback(). - "c" and "typeid" in the create() method of multiprocessing.managers.Server and multiprocessing.managers.SharedMemoryServer. - "obj" in weakref.finalize(). Also allowed to pass arbitrary keyword arguments (even "self" and "func") if the above arguments are passed as positional argument.

* bpo-30306: release arguments of contextmanager (GH-1500)Martin Teichmann2018-01-281-0/+47
| | | | | | | | | | | | | | | | The arguments to a generator function which is declared as a contextmanager are stored inside the context manager, and thus are kept alive, even when it is used as a regular context manager, and not as a function decorator (where it needs the original arguments to recreate the generator on each call). This is a possible unnecessary memory leak, so this changes contextmanager.__enter__ to release the saved arguments, as that method being called means that particular CM instance isn't going to need to recreate the underlying generator. Patch by Martin Teichmann.

* bpo-10049: Add a "no-op" (null) context manager to contextlib (GH-4464)Jesse-Bakker2017-11-231-0/+10
| | | | | Adds a simpler and faster alternative to ExitStack for handling single optional context managers without having to change the lexical structure of your code.
* bpo-31370: Remove support for threads-less builds (#3385)Antoine Pitrou2017-09-071-5/+1
| | | | | | * Remove Setup.config * Always define WITH_THREAD for compatibility.
* bpo-30266: support "= None" pattern in AbstractContextManager (#1448)Jelle Zijlstra2017-06-091-0/+10
| | | | | contextlib.AbstractContextManager now supports anti-registration by setting __enter__ = None or __exit__ = None, following the pattern introduced in bpo-25958.
* bpo-29692: contextlib.contextmanager may incorrectly unchain RuntimeError ↵svelankar2017-04-111-0/+23
| | | | | | | | | | (GH-949) contextlib._GeneratorContextManager.__exit__ includes a special case to deal with PEP 479 RuntimeErrors created when `StopIteration` is thrown into the context manager body. Previously this check was too permissive, and undid one level of chaining on *all* RuntimeError instances, not just those that wrapped a StopIteration instance.
