Serhiy Storchaka added the comment: There is the _compat_pickle module that purposed to support backward and forward compatibility for renamed or moved classes and modules.
StringIO.StringIO in 2.x corresponds to io.StringIO or io.BytesIO. The problem is that we can't determine what of classes is a match in every concrete case, especially if StringIO.StringIO is empty. But since cStringIO.StringIO is not pickleable either, I now think that it is not worth to support to support compatibility with pickled StringIO.StringIO instances. ---------- resolution: -> wont fix stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22890> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
