[Mailman-Users] Adding Mhonarc to existing Mailman installation

2007-02-20 Thread vancleef 
I am building a new Mailman 2.1.9 installation tree, and want to configure
it with Mhonarc and Mnogosearch.  I notice that the Mhonarc patches
change the config.pck version number from 96 to 96.2 because there
seem to be some changes to the file definition.

I have signed up on the mmi  mailman-mnogosearch mail list and see
what's involved, but have mailman-specific questions.

What happens if I move a config.pck running on stock 2.1.9 (version
96) to this new tree?  Is there something in Mailman that figures out
how to remunge the config.pck file?

Yes! This is the key to migrating a list to a new version in any
context. See the definition of CheckVersion() in Mailman/MailList.py.

Whenever a list is loaded from config.pck (or even a 2.0.x config.db),
the data version from the file is compared to the version of the
installation, and if it is less, Update is imported from
Mailman/versions.py and called to migrate the list data to the current
version. This is why you can drop a config.pck from an older version
into a running newer version and it just works.
