I have a bit of code using a simple tcp socket setup to test something.
We run pylint --errors-only
on our python files, generally as a way to validate all our code
using the trick defined in http://www.logilab.org/blogentry/78354, we could start adding to pylint a generic astng plugin that would help him to understand such things from the stdlib (there is also various tickets/comments about hashlib in the tracker).
That would be a great improvment indeed. Any volunteer ? :)
Beside this, I don't think there is other options than disabling the message.
