Yes, that's a correct behaviour in 3.4 and 3.5. See #20710 for details.

There is no bug here. `TarInfo.create_gnu_header` is an unbound method, that indeed requires first argument 'self'. `TarInfo.frombuf` is a classmethod, so it doesn't need a 'cls' arg. Signature, by default and by design, only shows arguments that need to be passed to correctly execute the given callable.

Yes, I think it should work. |
