Hi!
I'm looking at trunk/Python/sysmodule.c, function PySys_SetArgv(). In that function, there is code like this:
PyObject* path = PySys_GetObject("path"); ... if (path != NULL) { ... }
My intuition says that if path==NULL, something is very wrong. At least I would expect to get 'None', but never NULL, except when out of memory. So, for the case that path==NULL', I would simply invoke Py_FatalError("no mem for sys.path"), similarly to the other call there.
PySys_GetObject may return NULL after the user has removed sys.path with delattr(sys, 'path'). There are valid applications for removing sys.path.
Or before sys.path is initialized using PySys_SetPath(). Trust me, this code is as it should be. -- --Guido van Rossum (home page: http://www.python.org/~guido/)
