| I think that is true. On the other hand, it was a bit of a surprise to | find a BTree in ZGlobals. Maybe they're hiding somewhere else, too. At least, the script didn't found another one. It did found 7800 objects total, of which one was a BTree (ZGlobals). Now, in 2.7 I get this output (starting zope via 'zopectl debug'):
app <Application instance at 414c8c80> app._p_jar <Connection at 414ac74c> app._p_jar.root() {'Application': <Application instance at 414c8c80>, 'ZGlobals': <OOBTree object at 0x414d1c60>, 'RefreshData': {'auto': {'CCHS': 1}, 'products': {'Archetypes': {'dependent_products': ('CCHS',)}}}}
Which looks sane to me. But if I copy the same Data.fs to another instance with Zope HEAD, the "AttributeError: data" is there again. It *seems* to me that the root PersistentMapping is not being unpickled correctly.
