Consider the case of a weakref proxy (the only proxy type in the stdlib): for that, you never want to serialise the proxy, you want to serialise the original object. To correctly serialise a proxy object, you have to somehow ensure: - the proxy gets serialised - the target gets serialised - the two get hooked up again at the far end Now consider what happens if you have *two* proxies both pointing at the same target: how do you ensure that, when deserialised, both proxies still share a target? In the general case, you can't - so pickle doesn't even try. Instead, serialising a proxy serialises the original object - if you want to do something else, you need to decide for yourself how to recreate the cross-references correctly on deserialisation. ---------- nosy: +ncoghlan _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14577> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
