Problem: if you implement a frozendict type inheriting from dict in
Python, it is still possible to call dict methods (e.g.
dict.__setitem__()). To fix this issue, pysandbox removes all dict
methods modifying the dict: __setitem__, __delitem__, pop, etc. This
is a problem because untrusted code cannot use these methods on valid
dict created in the sandbox.
You can redefine dict.__setitem__.
oldsetitem = dict.__setitem__
def newsetitem(self, value):
# check if self is not frozendict
...
oldsetitem(self, value)
....
dict.__setitem__ = newsetitem
