`inspect.getmembers_static` triggers `__getattribute__`

Bug report

inspect.getmembers_static is documented as not triggering __getattribute__, but it can trigger it via dir. For example the following hits the recursion limit:

class A:
    def __getattribute__(self, name: str) -> Any:
        getmembers_static(self)
        return "all attrs exist!"

A().anything

(A workaround for examples like this one is to add the base cases required by dir to __getattribute__:

if name in ("__dict__", "__class__"):
    return object.__getattribute__(self, name)

(The __dict__ case is not always needed depending on the __dir__ implementation.))

Switching getmembers_static to use dir_static (gh-55979) would fix this problem, I believe. getmembers_static already documents that it can't find the dynamically created attributes, etc. that getattr_static can't find, so I don't think such a change would be breaking.

Your environment

• CPython versions tested on: 3.11.0
• Operating system and architecture: Linux-based, x86_64

inspect.getmembers_static の実装と、gh-55979 で参照されている dir_static の作業から始めてください。再帰の例を再現し、その後、メンバーの検査で dir を介して getattribute が呼び出されなくなったことを確認してください。報告された動作が修正され、動的に作成される属性に関する文書化された制限を変更していなければ完了です。
