problems with nnimap

problems with nnimap

[Joakim Verona]

Hello,

Im using a recent cvs gnus and I'm having some problems with nnimap. 

- gnus and the imapd doesnt have the same view of which messages are
  in my inbox. How can I sync them again? Preferrably without loosing
  my marks and so on if possible.

- when moving mail from one folder to another, a very very slow expire
  process starts. For each moved mail gnus counts from 0 to about
  90000. There are perhaps 500 messages in the folder, so this is odd.
  
  Is it possible to reset the message counter to some sane value?

I use a recent cvs gnu emacs and a recent cvs gnus. 
I use dovecot as imapd.

The above mentioned operations work well with for instance thunderbird
as imap client.

Cheers,
/Joakim

As a test, open the server buffer then turn off the agent for your
nnimap server.  Then open the summary buffer to see if all is well.
If that clears up the problem, then the agent's local cache is out of
sync with your nnimap server.  As a fix, locate and delete the agent's
.overview file for this mail box.

I checked in an update on 9 Sept that replaces the expiration function
with an optimized function.  If you're not using it, please give it a
try.

I use two different machines with different home directories but the
same gnus configuration (i.e. same IMAP servers, etc.).  With the
agent enabled it seems impossible to have either of the machines note
any changes to an IMAP folder made by the other machine.  In effect I
have to delete the agent .overview files each time I sit down at a
machine.

Is this the way it is supposed to be?

(As an aside, using the cache rather than the agent displays the same
problems.  At the moment I'm running without either.)

I don't think so. I have tried to provide more information to the
developers in this matter by activating the *imap-log* "(setq imap-log
t)" Unfortunately at the time I could not reproduce the error so I
gave up (just to be struck by the same problem the next session and
then I really gave up and disabled the agent for imap.)

So if you can reproduce the problem easily. It would be a good idea
to produce an *imap-log* while you are seeing this problem. I'm sure
the developers will have a better chance to fix this then.

It is certainly not the desired outcome.  However, nnimap and the
agent are functioning as intended.  The fix will require changes to
nnimap, the internals, the agent, and the cache.

Thanks for the answer.

At least now I know not to keep going back and trying again :-)

Probably not.  What files are shared between your machines?  If you
share some of Gnus' files, you might have to share all of them.  Best
is to not share anything, except possibly ~/.emacs and ~/.gnus.

And this isn't just the documented problem with the *Group* buffer
unread count being an estimate?

No files that gnus modifies itself as part of book-keeping.

That's the situation (i.e. I share only .emacs and .gnus).

No.

On machine A I enter a group, scan the list of articles then quit the
group.  On machine B I enter the same group, delete an article (using
B DEL) and quit.  On machine A I enter the group again and the article
deleted on machine B is still shown.  Attempting to read the article
gives the usual message about it having disappeared.

The only way I've found to get out of this has been to delete the
agent data on machine A.

Right.  I believe this should work.  Gnus on machine A searches for
which articles exist, when you enter the group, and should only show
those.  Machine A was online, right?  Not in disconnected mode, so it
was using the agent cache only?

Do (setq imap-log t) on machine B and collect the output generate
during B DEL, and then do (setq imap-log t) on machine A, and collect
the output generated when entering the group.

For the record: I do have the same problem for a while through Oort
and No Gnus.

I'll look into the imap logs (and send them) as Simon suggests, but I
had done that before (the "looking at").
