dovecot - Sep 2010 - Vpopmail support broken

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

My apologies if I'm posting for information which has already been
supplied to the list.  I searched and all I found was people talking
about the change in 2.0.3, but no details on the commit other than "I
was tired of people telling me it crashes".

We have not received any reports for the 5.4 or 5.5 branch of vpopmail
causing crashes in Dovecot.  That being said, if there is a problem,
we would like to provide a fix.

Again, if details on the specifics of the problem have been supplied,
I apologize.  Can anyone please provide me some reproduction details
for Dovecot 2.0.3's vpopmail plugin compiled against vpopmail 5.4.30+
or 5.5.0?

Removing the "vpopmail support broken" line from the configure script,
compiling and running seemed to work short-term.  I was able to
authenticate against the vpopmail plugin.  I tested with vpopmail
5.4.32 and 5.5.0 using the cdb authentication module.

Thanks!

I guess the problem started when people started trying vpopmail 5.5:

http://markmail.org/message/ylt62t2yyqqfc7dg
http://markmail.org/message/ykb7qujikzlsvvbe
http://markmail.org/message/3cjscs7wgvbj65dw

I tried to fix 5.5 with this change:

http://hg.dovecot.org/dovecot-1.2/rev/597e18c0bc7e

But I heard that it's now crashing when doing that call. (I'm not sure
which ones of those above problems are with this change and which ones
aren't.) And apparently that also completely broke 5.4.

I'm not entirely sure about 5.4 problems. I think I remember someone
saying that even when reverting the above change it didn't work.

I guess the problem is with MySQL.
