[Python-Dev] Py_ssize_t (original) (raw)

My suspicion is that building Python for an 64-bit address space is still a somewhat academic exercise. I know we don't do this at Google (we switch to other languages long before the datasets become so large we'd need a 64-bit address space for Python). What's your experience at EWT?

Two people had some difficulty building non-upgraded third-party modules with Py2.5 on 64-bit machines (I think wxPython was one of the problems) but they either gave up or switched machines before we could isolate the problem and say for sure whether Py_ssize_t was the culprit. I had remembered the PEP saying that there might be some issues for non-upgraded third-party modules and have wondered whether others were similarly affected.
