which version of curio are you using? I am not aware of this issue.

The direct problem here is that sock in your context is a coroutine, which of course doesn't have a bind method.

But, I don't know why sock = socket.socket() returns a coroutine. It's only possible if curio API changed.

Can you paste your code?

The above exception was the direct cause of the following exception:

curio.version
'0.7'

This is the ssl.py in Curio.

Your problem is related with issue 225 in Curio, which I just opened.

You can either switch to wip branch or change the source code of hyper2web.

Just in case you are new to coroutines, this is a great tutorial from the author of Curio.

Anyway, thank you very much for trying out my framework. Your feedback is the most valuable. Feel free to discuss anything related to this framework. (Feature requests, docs ...)

Answer 7 · 2017-07-22T05:59:16.000Z

The issue has been fixed in master branch sslsocket.py

        csock = ssl_context.wrap_socket(sock)
        while True:
            try:
                csock.send(None)
            except StopIteration as e:
                sock = e.value
                sock.bind(address)
                sock.listen()
                return sock

I have not updated the repo on pypi yet. Will close this issue after pypi update.

Has pushed the fix to pypi
