Here's an idea: create a simple script that manufactured a module which set up the Zope configuration, "filled in" for BTree in sys.modules, and got a hold of Zope.app(), causing ZGlobals to be replaced by a new-style BTree due to the above magic. People upgrading to 2.8 with databases created by Zope versions older than 2.3 would still need to run convertBTrees inside a different Zope version, but people upgrading databases created in versions equalling or later than 2.3 wouldn't because we stopped using the old BTree module for anything except ZGlobals after 2.3 AFAICT.
Actually, given my findings later in this email, this isn't even
necessary.
Right. Whew.
I checked in the necessary fix for PersistentMapping. There was a change in the data structure and I had to add some logic to convert some old state.
I also had to check in a %$#@ travesty because Data.fs.in still has references to BoboPOS.
With these changes, I can create a database with 2.6 and open it with the head.
Thanks Chris for helping us figure out that this was easier than we thought. :)
