[issue15198] multiprocessing Pipe send of non-picklable objects doesn't raise error
Richard Oudkerk shibt...@gmail.com added the comment: Then I doubt this is a bug in Python. If your class does not override __reduce__, __reduce_ex__ or __getstate__/__setstate__, then it is probably one of the attributes of your instance which is causing the problem. You could try to find out which one by trying cPickle.loads(cPickle.dumps(attribute, -1)) for each attribute of an instance of your class to see if it raises an error. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15198 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

What do you mean by hang? Do you mean that send() succeeds and recv() raises an error. That might cause your *program* to hang, but send() itself should not hang. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15198 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Richard Oudkerk shibt...@gmail.com added the comment: What type of object did you try to send, and how can the problem be reproduced? There are plenty of types which don't support pickling, and where pickling only succeeds in producing invalid data which cannot be successfully unpickled. The exception raised when unpickling will depend on the type of the object. -- type: crash - behavior ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15198 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
