I've added a field to all PyObjects in the interpreter which is of type PyObject*. Most of the time this pointer is NULL but occassionally I want to track some information in there. The problem I'm running into is that I can add a reference to a PyObject inside any of my PyObjects, but it seems that there isn't any one path that all objects follow on destruction so that I can later Py_DECREF that reference.
Eventually most of the types seem to call PyObject_Free, but this gets called with void* and it seems it isn't always the case that PyObject*s are passed in. Where is the best place to implement something like this? It really won't work to implement this in the destructor of each of the individual types because other types added later won't know to DECREF this field on destruction. Any hints would be appreciated. Hopefully I'm just missing something simple. -- http://mail.python.org/mailman/listinfo/python-list
