Why? We don't want it to crash the embedding app (which might be another python interpreter), but if the sandboxed interpreter itself crashes, is that so bad? The embedding app should just act as though that interpreter exited, possibly with a status code. > B.

Can't force a connection, so that the other interpreter is free to ignore them. Maybe even make it lockable, like sockets -- but it isn't something worth promising. > C.

Note that Brett's assumption of shared extension modules violates this -- but I'm not sure why he needs to assume that. (Because of the init-only-once semantics, I'm not even sure it is a good idea to share them.) > D. A given piece of Python code cannot access or communicate > with certain Python objects in the same interpreter. Why not? Is this just a way of allowing lightweight subinterpreters? Or do you really mean that they can't replace or modify certain objects, such as the permission-controlling code? > E.

Or are you just saying that it will behave as if its builtins were segregated, and not see changes made by another interpreter? -jJ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
