Serhiy Storchaka added the comment: Issue23403. But looks it is early yet for this. Note that this patch doesn't modify protocols. It just makes the pickler more smart and able to serialize more objects with existing protocols. It is the same as add pickle support for some type that didn't support the pickling before. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23611 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor added the comment: It is used in multiprocessing and this is not configurable. Oh, it would be nice to switch to version 4 by default, or make it configurable. I read that the version 4 is faster. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23611 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Serhiy Storchaka added the comment: Pickle is backward compatible and Python 2 usually is able to unpickle data pickled by Python 3 with protocol 3. The patch doesn't break compatibility. Current default protocol is 3 for compatibility with older Python 3 versions. It is used in multiprocessing and this is not configurable. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23611 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue23611] Pickle nested names with protocols 4
STINNER Victor added the comment: Hum, I don't know well the pickle module. Is it backward compatible? Should Python 2 be able to unserialize data serialized by Python 3? If yes, can you patch break this compatibility? It is unclear to me if it makes sense to even modify protocols different than the latest version. -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23611 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23611] Pickle nested names with protocols 4
New submission from Serhiy Storchaka: Proposed patch allows Python implementation of the pickle module to pickle nested names (e.g. methods) with protocols 4. Pickled data is compatible with old releases. If this is good I'll write C implementation. -- components: Library (Lib) files: pickle_nested_names.patch keywords: patch messages: 237548 nosy: alexandre.vassalotti, pitrou, serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Pickle nested names with protocols 4 type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file38390/pickle_nested_names.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23611 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
