> OpenWrapper was added in ce3a72aec6eaa0293c397c8d0407f7afe0072b2f (issue1267) > and was only used to set __builtin__.open It is useless in CPython, since CPython always use the C implementation of the io module, and in the io module, io.OpenWrapper is just an alias to io.open. $ python3 Python 3.9.2 (default, Feb 20 2021, 00:00:00) >>> import io >>> io.OpenWrapper is io.open True > (I suppose that at thet moment dumbdbm.py still set open as a class > attribute). I failed to find where in Lib/dbm/dumb.py the open() function is used to define a method. Maybe the code changed since OpenWrapper was added? At commit ce3a72aec6eaa0293c397c8d0407f7afe0072b2f, the io module was only implemented in Python (Lib/io.py, _io exist didn't exist). It was reimplemented in C in Python 3.1. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43680> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
