New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>: In Python 3 different opcodes are used for pickling integers with protocol 1 and higher. But pickling with protocol 0 always uses the LONG opcode. In Python all such integers are unpickled to the long instances.
Proposed PR makes integers that fit in a signed 32-bit integer be pickled with the INT opcode. This will decrease the size of a pickle (minus one byte 'L' per integer), speeds up pickling and unpickling, and makes these integers be unpickled to int instances in Python 2, that will save a memory. ---------- assignee: serhiy.storchaka components: Library (Lib) messages: 306285 nosy: alexandre.vassalotti, serhiy.storchaka priority: normal severity: normal status: open title: Pickle 32-bit integers with protocol 0 as INT instead of LONG type: enhancement versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32037> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
