[ZODB-Dev] problem with broken

[Adam GROSZER]

Hello,

I'm having a problem with broken objects here.
It's coming when I'm trying to evolve generations and the generation
just touches all objects in the ZODB to store them again with the
non-deprecated classes.

The code is like this:
    storage = context.connection._storage

    next_oid = None
    n = 0
    while True:
        oid, tid, data, next_oid = storage.record_iternext(next_oid)

        obj = context.connection.get(oid)
        # Make sure that we tell all objects that they have been changed. Who
        # cares whether it is true! :-)
        obj._p_activate()
        obj._p_changed = True
        
        if next_oid is None:
            break
