logging module LogRecord `__init__` mismatch

[aminalaee]

According to the Python docs for the LogRecord in logging module the msg argument and property is a string:
https://docs.python.org/3/library/logging.html#logging.LogRecord

In the typeshed, the attribute is set to a str:

typeshed/stdlib/logging/__init__.pyi

Line 392 in dd2818a

msg: str

But the msg input argument is set to object:

typeshed/stdlib/logging/__init__.pyi

Line 407 in dd2818a

msg: object,

And looking at the source the argument is not changed at all:
https://github.com/python/cpython/blob/7f760c2fca3dc5f46a518f5b7622783039bc8b7b/Lib/logging/__init__.py#L305

Unless this is for a backwards-compatible version, I guess this is a mismatch.

I think we should just use str everywhere. If you are passing a non-string, and it isn't converted to a string anywhere in logging, it may fail when some completely unrelated code handles the log records elsewhere. IMO this is exactly what type checking is supposed to avoid.

But in that case type checking is actually stricter than the implementation, and causes mismatch between typeshed and python docs and implementation.
