The sandbox code is there and "mostly working", but it is lacking a champion. It has been in this state for many years now (it is actually impressive that it still roughly works). Realistically, though, to answer the question of its prospects, it depends entirely on whether someone would be ready to become involved in PyPy and help maintain and develop it. As usual with Open Source, we can't predict when (and if) this will occur. From our point of view, it seems to attract occasional attention like yours, but we just have too many things to work on. > If anyone can suggest what I might be doing wrong, I would greatly > appreciate. You're not doing anything wrong, just stumbling on a mixture of old and new code. In the case of 'pypy_jit_depthmap_add', it's because we recently added vmprof support and didn't think about sandboxing. The fix is probably easy: we need a few "sandboxsafe=True" keyword arguments in rpython/jit/backend/llsupport/codemap.py. The issue with 'fcntl' is more obscure and involves much older code. In that case we need the sandboxed interpreter to ask the outside what to do---which should occur automatically, but doesn't, for reasons I'm still investigating. I suspect it's related to the XXX in the comment of select_function_code_generators() in rpython.translator.c.node. (I think with minimal effort we can finally get rid of the "oldstyle" functions mentioned there.) A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
