MountedFileStorage, 0.02.
Ok, so the DC guys have been talking about allowing multiple ZODB support, but I couldn't see a way to use it. A bit of trawling through the CVS and I found the guts of a MountedItem object which has now been removed. Using that as inspiration and a source of pointers, I've bolted together a really simple Product for mounting multiple ZODB files onto a Zope installation.
You should also check out the MountedDatabases section of the ZODB Wiki.
First of all, you need to be running a really really recent CVS version of Zope. 2.2alpha1 isn't good enough. Then install this product (it unpacks in lib/python/Products/MountedFileStorage).
Select Mounted FileStorage from the product add list.
Mounted FileStorage
For file put nifty.fs. Leave path blank, and put nifty as the id, click create.
file
path
nifty
create
You've now got an empty ZODB installed.
_WARNING_: This is really really untested stuff. It Works For Me. Not To Be Taken Internally. Do Not Come Crying To Me If It Breaks Your Zope Install.
If you want to play with this stuff, you really should back up your Data.fs first.
For more info, see the online Help. In particular, check out the known bugs and problems section.
Security Issues: There probably are some. I've no idea what they might be. The product makes a really simple-minded effort to not allow badness through (any filename with a / or \ in it). Don't give access to the permission Mount FileStorages to anyone that you don't trust, though. Note that this includes anyone with Manager role on the system. Note also, though that you can only mount existing files that are in var/.
