Summary: AttributeError, get_statistics_start_date

Initial Comment:
python2.5 in Ubuntu I start sb_server and just enter the remove server and remote proxy and press the Save button. Then I get this error:


500 Server error

Traceback (most recent call last):

Wow, this is an ugly one (quote from spambayes.message.Message: This whole
message info database thing is a real mess). Anyway, the fix is to do this
in State.close() method of sb_server.py:

spambayes.message.Message().message_info_db = None

instead of this:

spambayes.message.Message.message_info_db = None

Notice the difference? spambayes.message.Message.message_info_db should be
a class attribute, but it's a property (see the Message class for the messy
details). The latter statement creates a class attribute, which blows away
the property object. At that point the logic to create a new
message_info_db is hidden forever in Message._get_class_message_info_db()
which will never be called again. It would probably be good to at least
make a set of public class methods on Message for managing the
message_info_db so we don't need to use such a hackish way to discard the
old one and/or create a new one.

I ran into this today too. I tracked it down to sbserver.py, the close()
function of the State class:

        if self.mdb is not None:
            self.mdb.store()
            self.mdb.close()
            self.mdb = None
            spambayes.message.Message.message_info_db = None

Commenting out the "self.mdb.close()" and
"spambayes.message.Message.message_info_db = None" lines fixes the problem.
I'm not certain that the close line has to be removed yet, though I suspect
it does.

How do we get this fixed in the next release?
