[docs] [issue10436] tarfile.extractfile in "r|" stream mode fails with filenames or members from getmembers()

[flying sheep]

flying sheep added the comment:

well, we should just allow

extractall(members=['foo', 'bar'])

currently members only accepts TarInfo objects, not filenames, but it’s easy to accept both.

https://github.com/python/cpython/blob/74683fc6247c522ae955a6e7308b8ff51def35d8/Lib/tarfile.py#L1991-L1999

sth like:

filenames = set()
for member in members:
    if isinstance(member, TarInfo):
        # do what’s done now
    else:
        filenames.add(member)

for tarinfo in self:
    if tarinfo.name in filenames:
        self.extract(tarinfo)
