Bug report received in Debian. User is having occasional trouble with Gmail
driver crashing, indicates problem may have started after switching to Gmail.
Gmail driver merged to tree in 81b86fb74 on 2008-01-03 and recently released
in beta tarballs.
BT shows:
File "/var/lib/python-support/python2.4/offlineimap/folder/Gmail.py", line 102, in processmessagesflags
attributehash = imaputil.flags2hash(imaputil.imapsplit(result)[1])
File "/var/lib/python-support/python2.4/offlineimap/imaputil.py", line 88, in imapsplit
for i in range(len(imapstring)):
TypeError: len() of unsized object
imap debug log shows:
imap: 29:58.16 > BEAL75 UID STORE 4887 +FLAGS (\Deleted)
imap: 29:58.47 < BEAL75 OK Success
imap: 29:58.47 matched r'(?P<tag>BEAL\d+) (?P<type>[A-Z]+) (?P<data>.*)' => ('BEAL75', 'OK', 'Success')
imap: imapsplit() called with input: None
imap: imapsplit() got a non-string input; working around.
looking at code for Gmail.py processmessagesflags, comments from Ricardo
indicate it was copied from the same function in folder/IMAP.py.
However, folder/IMAP.py has checks for this, added 2002-07-12 in
5342dacc & 817a10ce. Suspect that Gmail author believed those checks
superfluous for Gmail.
Copied checks from folder/IMAP.py to folder/Gmail.py.
New repository/folder classes to support "real deletion" of messages
thorugh Gmail's IMAP interface: to really delete a message in Gmail,
one has to move it to the Trash folder, rather than EXPUNGE it.
