Hi, When you call extractfile() on a TarFile, the result is a buffered version of a _FileInFile pseudo-file. When fileno() is called on this resulting file, fileno() it not exist (understandably) and an AttributeError is raised. I would like to suggest raising an io.UnsupportedOperation instead, so that file would act more like other file-like objects. _______________________________________________ Python-Dev mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/JP4EYNRQOZ6PSEVYUJKS5HBHDR6VSKWF/ Code of Conduct: http://python.org/psf/codeofconduct/
