* [3.9] bpo-46032: Check types in singledispatch's register() at declaration ↵Miss Islington (bot)2021-12-261-1/+69
| | | | | | | | | | | | | | time (GH-30050) (GH-30254) (GH-30255) The registry() method of functools.singledispatch() functions checks now the first argument or the first parameter annotation and raises a TypeError if it is not supported. Previously unsupported "types" were ignored (e.g. typing.List[int]) or caused an error at calling time (e.g. list[int]). (cherry picked from commit 078abb676cf759b1e960f78390b6e80f256f0255) (cherry picked from commit 03c7449fbc7c57f5e0365f234a0b65c1dde763f2) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* [3.9] bpo-45678: Fix `singledispatchmethod` `classmethod`/`staticmethod` bug ↵Alex Waygood2021-11-041-1/+140
| | | | | | | | | | | (GH-29394) This PR fixes a bug in the 3.9 branch where ``functools.singledispatchmethod`` did not properly wrap attributes such as ``__name__``, ``__doc__`` and ``__module__`` of the target method. It also backports tests already merged into the 3.11 and 3.10 branches in #29328 and #29390. Co-authored-by: Łukasz Langa <lukasz@langa.pl>
* [3.9] bpo-39679: Fix `singledispatchmethod` `classmethod`/`staticmethod` bug ↵Alex Waygood2021-10-281-0/+42
| | | | | | | | | | | | | (GH-29087) This commit fixes a bug in the 3.9 branch where stacking `@functools.singledispatchmethod` on top of `@classmethod` or `@staticmethod` caused an exception to be raised if the method was registered using type-annotations rather than `@method.register(int)`. Tests for this scenario were added to the 3.11 and 3.10 branches in #29034 and #29072; this commit also backports those tests to the 3.9 branch.

* bpo-17005: Move topological sort functionality to its own module (GH-20558)Miss Islington (bot)2020-06-011-270/+1
| | | | | | | | | The topological sort functionality that was introduced initially in the functools module has been moved to a new graphlib module to better accommodate the new tools and keep the original scope of the functools module.

* 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.
