[3.9] bpo-46032: Check types in singledispatch's register() at declaration time (GH-30050) (GH-30254) (GH-30255)

2021-12-26T12:23:23+00:00

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]).

[3.10] bpo-27718: Fix help for the signal module (GH-30063) (GH-30080)

2021-12-13T10:43:13+00:00

Functions signal(), getsignal(), pthread_sigmask(), sigpending(),
sigwait() and valid_signals() were omitted.

correct __module__.
