bsddb in python 2.5.1

[BjornT]

Have a rather big problem with bsddb I can't figure out. I upgraded an
Ubuntu machine from 7.05 to 7.10 which upgraded python to 2.5.1

I run a local website that uses bsddb, and suddenly I get a version
mismatch error with bsddb and I can't access my database anymore

I noticed in the 2.5.1 release notes:

- fixed a bug with bsddb.DB.stat: the flags and txn keyword arguments
were transposed.

- Added support for linking the bsddb module against BerkeleyDB 4.5.x.

I know that when you upgrade Berkeley DB you're supposed to go through
steps solving this problem,but I wasn't expecting an upgrade. I've
tried to use different versions bsddb3, 4.4 and 4.5, (instead of bsddb
that comes with python 2.5.1) with different versions of Berkeley DB
installs (4.5 and 4.4 - built from source into /usr/local). But this
isn't working.

I can't seem a way to figure out how to recover my data. Please help. :

I have two versions of bsddb3 installed (only one is active) this is

from /usr/lib/python2.5/site-packages:
drwxr-xr-x 3 root root 4096 2007-11-03 15:01 bsddb3
-rw-r--r-- 1 root root 905 2007-11-03 15:39 bsddb3-4.4.2.egg-info
-rw-r--r-- 1 root root 905 2007-11-03 15:49 bsddb3-4.5.0.egg-info

This makes two installations, but how do you know that they really link
with two different versions of Berkeley DB?

I'm really at a loss of what I could do, except for reverting
back to Ubuntu 7.05.

What's wrong with upgrading the database files to 4.5? Just run the
proper db_upgrade binary.
