Re: [rdiff-backup-users] Long path problem

I used a simple shell script on a Linux ext3 filesystem:

        while mkdir aaaaaaaa && cd aaaaaaaa; do true; done

The path got to nearly 8000 characters long, and although cd was giving 
warnings about "getcwd: path name too long", it was still going when I 
killed it.

When I try to back up the root of this huge tree with rdiff-backup, I get 
the following error:

Processing changed file aaaaaaaa/aaaaaaaa/.../aaaaaaaa
Exception '[Errno 36] File name too long: 'aaaaaaaa/.../aaaaaaaaa'' raised 
of class 'exceptions.OSError':
  File "/usr/lib/python2.3/site-packages/rdiff_backup/robust.py", line 32, 
in check_common_error
    try: return function(*args)
  File "/usr/lib/python2.3/site-packages/rdiff_backup/rpath.py", line 922, 
in append
    return self.__class__(self.conn, self.base, self.index + (ext,))
  File "/usr/lib/python2.3/site-packages/rdiff_backup/rpath.py", line 669, 
in __init__
    else: self.setdata()
  File "/usr/lib/python2.3/site-packages/rdiff_backup/rpath.py", line 693, 
in setdata
    self.data = self.conn.C.make_file_dict(self.path)

Hope this helps,

Cheers, Chris.
