Re: [Duplicity-talk] Status of imap support?

[Michael Schneider]

I just replaced the google imap server by my providers server (imap.alice-dsl.net) in gmailbackend

result:

1.) imap.alice-dsl.net does not like SSL connects, duplicity fails with:

  File "/usr/lib/python2.6/site-packages/duplicity/backend.py", line 93, in get_backend
    return _backends[pu.scheme](pu)
  File "/usr/lib/python2.6/site-packages/duplicity/backends/gmailimapbackend.py", line 32, in __init__
    self._conn = cl('imap.alice-dsl.net', 993)
  File "/usr/lib/python2.6/imaplib.py", line 1137, in __init__
    IMAP4.__init__(self, host, port)
  File "/usr/lib/python2.6/imaplib.py", line 163, in __init__
    self.open(host, port)
  File "/usr/lib/python2.6/imaplib.py", line 1149, in open
    self.sock.connect((host, port))
  File "<string>", line 1, in connect
timeout: timed out

2.) after forcing port 143, another problem surfaces:
IMAP LIST: duplicity-full.2009-01-21T20:06:18+01:00.vol1.difftar.gpg test
Traceback (most recent call last):

  File "/usr/bin/duplicity", line 558, in main

    subj = m.getheaders("subject")[0]
IndexError: list index out of range


m.getheaders returns an empty list. Not being an IMAP expert, I cannot judge whether is behaviour is correct.
Is it save to skip empty headers when iterating over the messages in list() ?

I have no way to test this at all.  If someone has the means to test
against a generic IMAP server, please let us know how it works.
