This affects more use cases than just is_tarfile() and getmembers() results. is_tarfile() calls open() which is the root cause of the issue. Calling open() 2+ times will also cause the same issue. In addition to getmembers(), extracting the tar will also silently fail. (and possibly other operations). I've suggested a different fix in the comment on the PR: https://github.com/python/cpython/pull/26488#issuecomment-989367707 ---------- nosy: +andrei.avk title: tarfile.is_tarfile() modifies file object's current position -> tarfile.is_tarfile() and tarfile.open() when used with file object may cause tarfile operations to fail _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44289> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
