[Python-apps-team] Bug#590600: rdiff-backup to an nfs

[Denys Gavrysh]

I confirm this bug in version 1.2.8.
NFS share mounted on /backup. Output:


# rdiff-backup /bin/ /backup/
Exception '[Errno 116] Stale NFS file handle:

I just commented this lines in rpath.py file and exception has disappeared:


         if os.name != 'nt':
                 try:
                         return C.make_file_dict(filename)
                 except OSError, error:
                         # Unicode filenames should be process by the 
Python version
                         if error.errno != errno.EILSEQ and error.errno 
!= errno.EINVAL:
                                 raise
