bpo-42576: Raise TypeError when passing in keyword arguments to GenericAlias (GH-23656)

2020-12-05T16:24:38+00:00

Use `_PyArg_NoKeywords` instead of `_PyArg_NoKwnames` when checking the `kwds` tuple when creating `GenericAlias`. This fixes an interpreter crash when passing in keyword arguments to `GenericAlias`'s constructor.

Needs backport to 3.9.

[3.9] bpo-41116: Fix setup.py test for macOS Tcl/Tk frameworks (GH-23649) (GH-23650)

2020-12-05T04:26:59+00:00

If no explicit macOS SDK was specified, setup.py should check for
Tcl and TK frameworks in /Library/Frameworks; the previous commit
inadvertently broke that test.
