When I ported offlineimap from Python 2 to Python 3 I removed the Debug for
IMAP (imaplib2).
The reason was offlineimap was setting the Debug directly in imaplib2,
not using the proper way (using the IMAP4 argument). Because we are
removing the virtual_imaplib2, I removed this option.
I removed this line in offlineimap/init.py:303:
---8<---
300 dtype = dtype.strip()
301 self.ui.add_debug(dtype)
302 if dtype.lower() == u'imap':
-303 imaplib.Debug = 5
304
305 if options.runonce:
306 # Must kill the possible default option.
---8<---
With this patch, the debug level 5 is restored in imaplib if the user
set the -d ALL or -d imap in offlineimap.
