New submission from Antoine Pitrou <pit...@free.fr>:
In issue39681 we reestablished the fallback to read() when a file-like object doesn't provide readinto() in _pickle.c. However, doing so leads to lower performance and all file-like object should nowadays provide readinto() (simply by deriving from the right base class - e.g. io.BufferedIOBase). I propose to issue a DeprecationWarning when the fallback behaviour is selected, so that one day we can finally remove it. ---------- components: Library (Lib) messages: 362547 nosy: ogrisel, pierreglaser, pitrou priority: low severity: normal status: open title: Deprecate readinto() fallback path in _pickle.c type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39734> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
