I have a tar gz archive that fails to be extracted via tarfile.extractall(). By adding some debug code I found that at some point InvalidHeaderError is raised inside tarfile.next(). But the function just swallows the exception, because the offset isn't 0 (see https://github.com/python/cpython/blob/5368c2b6e23660cbce7e38dc68f859c66ac349ee/Lib/tarfile.py#L2334). Why does the function behave like this? I would expect an except rather than silently stopping extraction if the archive is damaged.
