STINNER Victor <[email protected]> added the comment:
I'm not sure that it could work because many C functions use caches using
static variables.
Just a random example:
int
_PyUnicode_HasNULChars(PyObject* s)
{
static PyObject *nul = NULL;
if (nul == NULL)
nul = PyUnicode_FromStringAndSize("\0", 1);
if (nul == NULL)
return -1;
return PyUnicode_Contains(s, nul);
}
If hash(nul) is computed in an interpreter, the same hash value will be used by
all interpreters. If interpreters use a different hash secret, you will have a
problem.
