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� �fr6 r6 r7 r� � sD z TarFile.addc C s� | j d� tj|�}|j| j| j| j�}| jj|� | jt |�7 _|dk r�t || j|j � t |j t �\}}|dkr�| jjtt | � |d7 }| j|t 7 _| jj|� dS )a] Add the TarInfo object `tarinfo' to the archive.
