This can be avoided by setting `recursive' to False. `exclude' is a function that should return True for each filename to be excluded. `filter' is a function that expects a TarInfo object argument and returns the changed TarInfo object, if it returns None the TarInfo object will be excluded from the archive. r� Nr z use the filter argument insteadr ztarfile: Excluded %rztarfile: Skipped %rr z tarfile: Unsupported type %rr� �filter)r� �warnings�warn�DeprecationWarning�_dbgr� r� r r� r� rN r� �addfiler� r> �listdir�addrs ) r� r� r� � recursive�excluder� r� r� �fr5 r5 r6 r� � sD * *z TarFile.addc C s� | j d � t j | � } | j | j | j | j � } | j j | � | j t | � 7_ | d k r� t | | j | j � t | j t � \ } } | d k r� | j j t t | � | d 7} n | j | t 7_ n | j j | � d S)a] Add the TarInfo object `tarinfo' to the archive.
