Thomas Kluyver added the comment: Here's a new version of the zf.open() patch following Martin's review (thanks Martin!). I agree that it feels a bit awkward having two completely different actions for zf.open(), but it is a familiar interface, and since the mode parameter is already there,

Martin Panter added the comment: I was mistaken about what test_wrong_cert() is doing. It tells the _server_ to check the _client’s_ certificate (the opposite way around from HTTPS for example). Now I understand this, I see it is fine for the client to raise ECONNRESET if the server rejected
