I don't know how you calibrate your expectations, Chris, but conflict
resolution is a property of (some) *storages*; the connectoins in
application servers have nothing to do with it. For objects served from
a ZEO storage, conflict resolution is only possible if:
- The underlying storage is conflict resolving (FileStorage is; none
of the others which ship with ZODB are).
- The storage server can import the class of the object under
conflict (this is why the BTrees code ships with ZODB, actually,
so that the storage server can use its conflict resolution hooks).
Installing the products containing application-defined conflict
resolution on the storage server is the only way to enable that conflict
resolution in a ZEO-backed deployment.
