Error in python 3.6 ssl.py: [...] File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 737, in __init__ self._context.verify_mode = cert_reqs File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 479, in verify_mode super(SSLContext, SSLContext).verify_mode.__set__(self, value) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 479, in verify_mode super(SSLContext, SSLContext).verify_mode.__set__(self, value) [Repeated] Crash is infinite recursion on super calls having to do with the verify_mode property Crash found when creating an SSL context for eventlet with flask-socketio, unfortunately easiest way to reproduce involves installing eventlet, flask, flask-socketio, and pyopenssl. I've included the smallest working example of the crash in python 3.6, attached code works in python 3.5. Note: I'm attempting to create a dependency-free version of the file which exhibits the same behavior, it's tricky to unwrap all the libraries leading to the issue. See https://github.com/miguelgrinberg/Flask-SocketIO/issues/193 for original post discovering bug. |

Attached a simpler version of the code with same error using only eventlet. |

It's a bug in eventlet's monkey patch, not a bug in Python's ssl module. I've seen a similar issue with gevent's monkey patch. |
