I'm getting the error below when trying to boot up a zope 2.13.7 using a Data.fs I took from a zope 2.8.12 instance. Having Products.ZSQLMethods-2.13.3 installed or not installed doesn't appear to be relevant. The fortunate thing, in this instance, is that the SQLMethods in that instance are not important to me so I'd be happy to delete them if I could. However, I tried with ./bin/zopectl debug

...

...

del app.www['id_of_a_zsql_method'] but that raises the same TypeError.

Any ideas? 2011-06-03 11:36:27 ERROR ZODB.Connection Couldn't load state for 0x5528 Traceback (most recent call last): File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/Connection.py", line 856, in setstate self._setstate(obj) File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/Connection.py", line 910, in _setstate self._reader.setGhostState(obj, p) File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/serialize.py", line 612, in setGhostState state = self.getState(pickle) File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/serialize.py", line 605, in getState return unpickler.load() TypeError: ('argument list must be a tuple', <class 'Shared.DC.ZRDB.DA.SQL'>, None) -- Peter Bengtsson, home www.peterbe.com fun donecal.com work www.mozilla.com
