Hello all, The following is the best test case I have so far for bug 1783. The behavior of the bug is that no CMethods from Persistent can be called indirectly when the __call_method__ hook is present. This means that I can't override any of __getstate__, __setstate__, _p_deactivate. #!/usr/bin/python import ZODB from Persistence import Persistent class P(Persistent): def __call_method__(self, meth, methArgs, methKW={}): return apply(meth, methArgs, methKW) p = P() p.__getstate__() #This throws exception! Persistent.__getstate__(p) TypeError: function requires exactly 0 arguments; 1 given -- . . . . . . . . . . . . . . . . . . . . . . . . John D.
