I've got a trouble importing a ZClass app to 2.9.8 from 2.6.1.
First, I've tried 2.8, and it worked but had the __new__ problem, so I've seen it is fixed in 2.9.8.
After the upgrade, all seemed to work. My ZClass is a container (with ExtFile). I've been able to create a new instance, then had trouble after uploading an ExtFile. The file is there, in the repository, but when I clicked over it, I get a fast scrolling in the log. After the restart, the ZClass instances and the Product in the control panel, gived me a maximun recursion depth, here the last part:
File "/usr/lib/zope2.9.8/lib/python/ZODB/serialize.py", line 597, in getState return unpickler.load() .... File "logging/__init__.py", line 1078, in _log File "logging/__init__.py", line 1064, in makeRecord File "logging/__init__.py", line 226, in __init__ # Must happen after ZopeStarter.setupInitialLogging() RuntimeError: maximum recursion depth exceeded in cmp
This is very strange: the traceback you show does not seem very deep. It should not raise a "maximum recursion depth exceeded". As always: when you see something which should not be there, debugging may be necessary for understanding... -- Dieter
