* bpo-44184: Apply GH-26274 to the non-GC-type branch of subtype_dealloc ↵Miss Islington (bot)2021-07-151-3/+11
| | | | | | | | | | | (GH-27165) (GH-27174) The non-GC-type branch of subtype_dealloc is using the type of an object after freeing in the same unsafe way as GH-26274 fixes. (I believe the old news entry covers this change well enough.) https://bugs.python.org/issue44184 (cherry picked from commit 074e7659f208051b6b973f7fdb654dd22b93aaa2) Co-authored-by: T.

* bpo-44647: Fix test_httpservers failing on Unicode characters in os.environ ↵Miss Islington (bot)2021-07-151-4/+13
| | | | | | | | on Windows (GH-27161) (#27169) GH-23638 introduced a new test for Accept: headers in CGI HTTP servers. This test serializes all of os.environ on the server side. For non-UTF8 locales this can fail for some Unicode characters found in environment variables. This change fixes the HTTP_ACCEPT test.

* bpo-42073: allow classmethod to wrap other classmethod-like descriptors ↵Miss Islington (bot)2021-07-153-1/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-27115) (GH-27162) Patch by Erik Welch. bpo-19072 (GH-8405) allows `classmethod` to wrap other descriptors, but this does not work when the wrapped descriptor mimics classmethod. The current PR fixes this. In Python 3.8 and before, one could create a callable descriptor such that this works as expected (see Lib/test/test_decorators.py for examples): ```python class A: @myclassmethod def f1(cls): return cls @classmethod @myclassmethod def f2(cls): return cls ``` In Python 3.8 and before, `A.f2()` return `A`. Currently in Python 3.9, it returns `type(A)`. This PR make `A.f2()` return `A` again. As of GH-8405, classmethod calls `obj.__get__(type)` if `obj` has `__get__`. This allows one to chain `@classmethod` and `@property` together. When using classmethod-like descriptors, it's the second argument to `__get__`--the owner or the type--that is important, but this argument is currently missing. Since it is None, the "owner" argument is assumed to be the type of the first argument, which, in this case, is wrong (we want `A`, not `type(A)`). This PR updates classmethod to call `obj.__get__(type, type)` if `obj` has `__get__`.

* [3.10] bpo-44630: Fix assertion errors in csv module (GH-27127) (GH-27129)Miss Islington (bot)2021-07-132-4/+14
| | | | | | | | | | | | | | | | | | | Fix incorrect handling of exceptions when interpreting dialect objects in the csv module. Not clearing exceptions between calls to PyObject_GetAttrString() causes assertion failures in pydebug mode (or with assertions enabled). Add a minimal test that would've caught this (passing None as dialect, or any object that isn't a csv.Dialect subclass, which the csv module allows and caters to, even though it is not documented.) In pydebug mode, the test triggers the assertion failure in the old code. Contributed-By: T. Wouters [Google] (cherry picked from commit 0093876328afa330224c9d887c18dee0b3117852) Co-authored-by: T.
