filter argument to Tarfile.extractall not recognized

[jaraco]

The argument exists in Python 3.8 and is documented, yet mypy raises an error.

 draft @ cat ext.py
import tarfile

tf = tarfile.open('foo.tar.gz')
tf.extractall(filter='abc')

 draft @ mypy ext.py
ext.py:4: error: Unexpected keyword argument "filter" for "extractall" of "TarFile"  [call-arg]
Found 1 error in 1 file (checked 1 source file)

Yes, this is just because the mypy 1.5 release is quite delayed. You can see that mypy's vendored copy of typeshed's stubs includes the filter parameter for Tarfile.extractall on the mypy master branch: https://github.com/python/mypy/blob/a8467c43fb6423cc3f7f330f361e6b5af0bf284f/mypy/typeshed/stdlib/tarfile.pyi#L294-L302

And the parameter also exists on the release-1.5 branch: https://github.com/python/mypy/blob/2ff7c0de571d434a9a1f82fa183d32fa32999b40/mypy/typeshed/stdlib/tarfile.pyi#L295-L301

But not on the 1.4.1 tag (1.4.1 is the latest mypy version): https://github.com/python/mypy/blob/3534bacc4c0d3c4b1983a533e2a36cce43f2ec9d/mypy/typeshed/stdlib/tarfile.pyi#L278-L280

For now, you'll just have to type: ignore it, but you'll be able to remove the type: ignore once mypy 1.5 is released, with a more up-to-date vendored copy of typeshed's stubs.

python/mypy#15588 is the tracking issue for mypy v1.5. None of us at typeshed really have any power to make the release come any faster :)
