* [3.10] bpo-44594: fix (Async)ExitStack handling of __context__ (gh-27089) ↵John Belmonte2021-10-051-0/+35
| | | | | | | | | | | | | | (GH-28730) Make enter_context(foo()) / enter_async_context(foo()) equivalent to `[async] with foo()` regarding __context__ when an exception is raised. Previously exceptions would be caught and re-raised with the wrong context when explicitly overriding __context__ with None..

* bpo-41229: Update docs for explicit aclose()-required cases and add ↵Joongi Kim2020-11-021-1/+58
| | | | | | | | | | | | | | | | | | | contextlib.aclosing() method (GH-21545) This is a PR to: * Add `contextlib.aclosing` which ia analogous to `contextlib.closing` but for async-generators with an explicit test case for [bpo-41229]() * Update the docs to describe when we need explicit `aclose()` invocation. which are motivated by the following issues, articles, and examples: * [bpo-41229]() * https://github.com/njsmith/async_generator * https://vorpus.org/blog/some-thoughts-on-asynchronous-api-design-in-a-post-asyncawait-world/#cleanup-in-generators-and-async-generators * https://www.python.org/dev/peps/pep-0533/ * https://github.com/achimnol/aiotools/blob/ef7bf0cea7af/src/aiotools/context.py#L152 Particuarly regarding [PEP-533](https://www.python.org/dev/peps/pep-0533/), its acceptance (`__aiterclose__()`) would make this little addition of `contextlib.aclosing()` unnecessary for most use cases, but until then this could serve as a good counterpart and analogy to `contextlib.closing()`. The same applies for `contextlib.closing` with `__iterclose__()`. Also, still there are other use cases, e.g., when working with non-generator objects with `aclose()` methods.
* [3.9] bpo-37116: Use PEP 570 syntax for positional-only parameters. (GH-12620)Serhiy Storchaka2019-06-051-2/+2
| | | Turn deprecation warnings added in 3.8 into TypeError.
* bpo-36492: Deprecate passing some arguments as keyword arguments. (GH-12637)Serhiy Storchaka2019-04-011-0/+10
| | | | | | | | | | | | | | | | | | | | | | 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.
