First post, recursive references with pickle.

[mark starnes]

Hi everyone, this is my first post to this group, so please be gentle.

I've written a class which, when I attempt to pickle, gives the error:

*** RuntimeError: maximum recursion depth exceeded

Is there a way to make pickle display data about what it's trying
to do? I'm thinking that if so, the recursive component will be
immediately visible, easing the bug hunt.

Any help would be appreciated.

BR,

Mark.

How about commenting out one by one the attributes of the object
you're trying to pickle until you find the problematic one(s) ?
Something like:

class MyClass(object):
...
def __getstate__(self):
del self.foo
return self.__dict__

Then do the same to the class of self.foo, and so on recursively,
until you find the real culprit.

HTH,
