Hi, I've started working on the integration of Zope 3.4 and ZODB 3.8 into Zope 2.11. I have a breaking test on ZClasses that I couldn't understand. I'd appreciate any help. The error is a max. recursion of an object that tries to load its state and something goes off. Here's a part of the traceback: File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZClasses/ZClass.txt", line 171, in ZClass.txt Failed example: c2 = test2.C() Exception raised: Traceback (most recent call last): File "/home/ctheune/Development/Zope2-upgrade/lib/python/zope/testing/doctest.py", line 1348, in __run compileflags, 1) in test.globs File "<doctest ZClass.txt[59]>", line 1, in ? c2 = test2.C() File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/Connection.py", line 801, in setstate self._setstate(obj) File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/Connection.py", line 859, in _setstate self._reader.setGhostState(obj, p) File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/serialize.py", line 604, in setGhostState state = self.getState(pickle) File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/serialize.py", line 597, in getState return unpickler.load() File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/serialize.py", line 471, in _persistent_load return self.load_oid(reference) File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/serialize.py", line 537, in load_oid return self._conn.get(oid) File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/Connection.py", line 235, in get obj = self._reader.getGhost(p) File "/home/ctheune/Development/Zope2-upgrade/lib/python/ZODB/serialize.py", line 569, in getGhost Christian -- gocept gmbh & co. kg - forsterstraße 29 - 06112 halle/saale - germany www.gocept.com - ct@gocept.com - phone +49 345 122 9889 7 - fax +49 345 122 9889 1 - zope and plone consulting and development
