Python 2.7 and PROTOCOL_TLSv1_2

[cwurld]

The Python 2.7 ssl module does not have a ssl.PROTOCOL_TLSv1_2. This causes django-sslserver version 0.20 to fail. This error goes away when I revert to version 0.19

What version of 2.7? 2.7.9 (released three years ago) should have this.

https://docs.python.org/2/library/ssl.html#ssl.PROTOCOL_TLSv1_2

2.7.6 - I guess I should update it.

I'm having the same problem on macos sierra with python 2.7.10

AttributeError: 'module' object has no attribute 'PROTOCOL_TLSv1_2'

✗ python

0.19 works fine.

I'm running into this problem with 2.7.14 and it looks to me like it's because PROTOCOL_TLSv1_2 is deprecated as of 2.7.13: https://docs.python.org/2/library/ssl.html#ssl.PROTOCOL_TLSv1_2

You can see in a IDLE session that my SSL configuration is working normally and the suggested replacement works fine, but PROTOCOL_TLSv1_2 can't be imported as it's deprecated:

but PROTOCOL_TLSv1_2 can't be imported as it's deprecated:

That's strange as "deprecated" just means "you shouldn't use this any more, it could be removed in the future" not, "this is gone."

That sounds like a Python bug report that either the implementation or docs need to be updated.

Yup you are right! This python installation had issues with TLS 1.2 and everything is working after recompiling python with the proper flags. Thank you for the helpful tool!

Great, just watch out for #64, my server will freeze when using django-sslserver if too many concurrent requests happen at once.
