Sporadic NNIMAP error with CVS gnus

Sporadic NNIMAP error with CVS gnus

[Arcady Genkin]

After upgrading to the latest CVS gnus from the CVS copy from Spring,
I *sometimes* get the following when entering an NNIMAP group.  I have
captured NNIMAP log and can provide the contents if necessary.

Thanks!

I realize that the problem is intermittent, however if you do the 
following it will really help me.
First, please delete gnus-agent.elc.  Second, whenever you start gnus 
set debug-on-error to t {M-: (setq debug-on-error t)}.
After doing this, you can continue to use gnus as you would normally. 
 If this error repeats, you'll be kicking into the debugger.  At that 
point, I'd like

1) the stack trace displayed by the debugger.
2) The contents of " *nntpd*".  Actually, I don't need everything, just 
the line gnus-agent-braid-nov was trying to read.  You can get this by 
selecting the *nntpd* buffer from the debugger then copying the line 
containing point.  I'd also appreciate some sort of marker to indicate 
where point was positioned in that line.

The last few commands in the NNIMAP log may be of interest.  Please send 
them by PM.

What is the contents of the  *nntpd* buffer when this happens?

As I replied to Kevin in private mail, it's the following:

 # ( 1) [PasteMusic.com      ] Free CDs at Paste, Gift Subscriptions for Cheap/New PasteArtist Brad Yoder + Ryan Adams, etc.

and the point is in the third column (right after the `#' character).

p.s.  Damn spam!

In the *nntpd* buffer?  That looks really wrong, how did a summary
buffer line end up in the server buffer?  Do you have any summary
buffer customizations that may leave data in the server buffer?

By ``server buffer'' you mean the `` *nntpd*'' buffer?  It looked
alright, as far as I could tell, but I would not know if there were
anything wrong with the actual format.

Not sure.  I have the following lines in my .gnus; perhaps there is
something wrong...

(add-hook 'gnus-summary-mode-hook
          '(lambda ()
             (local-set-key [(alt delete)] (quote gnus-summary-delete-article))
             (setq gnus-summary-line-format "%U%R%z(%2t) %I%(%[%-20,20n%]%) %s\n

Arcady,
Pls check the contents of the .overview file for the group that is 
getting this error.  It should be located at 
News/agent/nnimap/MAIL_SERVER_NAME/MAIL_BOX_NAME/.overview.  Does the 
line, "Free CDs ..." appear in this file EXACTLY as shown below?

If it does, run (gnus-agent-regenerate-group "GROUP_NAME") to repair the 
.overview.  This should fix your problem for now.  I'll check in new 
code tomorrow to improve the error checking.  What we're seeing right 
now is a symptom.  It may take some time to find the cause.

Yup.

It should contain NNTP protocol style feedback, that line above looked
like a summary buffer line which is wrong.

Looks harmless.  If this is reproducable, you could try tracking down
exactly what code inserts the data in the server buffer...

Yes, it does, just like that.

This simply truncated the .overview file to zero-length.  However,
when I entered the group the usual way, the .overview file got filled,
and the problem is gone for now.
