The problem is not to be observed anymore, it works fine!!!

I found and fixed 2 BTree bugs introduced in 3.9.0c2 that probably account for the problem you're seeing. Could you test against the 3.9 branch: svn://svn.zope.org/repos/main/ZODB/branches/3.9 and let me know if the fix corrects the problem you're seeing?

ContainedProxy isn't a container type. It is a generic proxy that ads __parent__ and __named__ attributes. Does it actually proxy a Python dict? What does foo.__class__ return where foo is one of these containers?

[ZODB-Dev] Strange lookup error...
Hello, I have just subscribed this list, to describe a strange error that occured for me. In the bugtrack people seem to be very precise in describing where the error is, I have no idea about where the error is, so I will not polute the bugtrack :-) I am sorry if writing to this list is not the right thing to do, feel free to guide me then :-). Background: --- After update of - an application, with some modules being renamed - python from 2.5 to 2.6 - zodb an updatescript is called to refresh the broken objects. The objects are stored in dict of type with a simple unicode key to the object mapping. The refresh of a broken object precedure is : - identify broken object - identify correct type - create an instance of that type - transfer state from the broken object to the new instance - reassign the new object in the dict. ( myDict[ id ] = newInstance ) --- Observation: --- Within the same transaction as the broken objects are refreshed, I can verify that I can lookup all objects.. After a commit, and close / open of the connection, I can not lookup some objects. But if I make a list of all items like : allItems = list( myDict.items() ) all ids and objects are represented in the allItems, and NO objects are broken, they look all fine. But for some ids amongst the allItems, "myDict[ id ]" throws a KeyError ( and "id in myDict" returns False )... It is about 25 objects or so out of a few tusind that fails I can not see anything special with those objects The FileStorage is last updated with a zodb3 version 3.8.0 --- The precedure is used to work fine, I have tried with different version of zodb3 from pypi, #bad zodb3 = 3.9.2 #bad zodb3 = 3.9.1 #bad zodb3 = 3.9.0 #bad zodb3 = 3.9.0c2 #ok zodb3 = 3.9.0c1 #ok zodb3 = 3.9.0b5 #ok zodb3 = 3.9.0a12 and it says, until version 3.9.0c1, it worked, but with 3.9.0c2 it started to fail. System Linux : - Python 2.6.2 - uname -iorm -> 2.6.27-gentoo-r8 x86_64 AuthenticAMD GNU/Linux Am I violating some rules of migration, or is it a bug introduced by version 3.9.0c2?? If it is an interesting bug to catch ( for me it is very interesting :-) ), I can test versions or patches.
