Osvaldo Santana Neto added the comment: I agree with Jelle about the fix's implementation. But I disagree of suggestion to implement lock at the application side.
I disagree because some external libraries may want to access os.environ in a concurrent fashion without lock acquiring. That's the case reported in my previous comment: urllib/requests.py (https://github.com/python/cpython/blob/master/Lib/urllib/request.py#L2468) iterates over os.environ with no lock control. How could I handle this issue in this case? Would it be a good idea implement the lock mechanism in current os._Environ (https://github.com/python/cpython/blob/master/Lib/os.py#L666) mapping class? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30441> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
