Broken ssl module: TypeError: __init__() got an unexpected keyword argument 'server_hostname'

[Glandos]

This is a continuation of what I am experiencing in #92 .

Here is the complete stacktrace, for reference:

I am using a virtualenv on an up-to-date Debian/testing (jessie).

It seems that grequests redefined an ssl module, that want to have the same API as Python 2.7. Unfortunately, they introduced server_hostname and other niceties in Python 2.7.9 that seem to have been backported in Debian. And the wrapper is now broken.
Maybe I'm missing something, somewhere… But now, I am unable to have results for all HTTPS sites. This is quite annoying 😄

It's because Urllib3/gevent became incompatible with the latest python2.7.8 version. There is an open urllib3 issue about it: urllib3/urllib3#482 .

[Glandos]

OK, that confirms my debugging session. But now, I have to sit and wait, cause I have no time to change something in a library I know nothing about…

[Cqoicebordel]

I have the same issue.
Is there a way to circumvent it ? Because in the meantime, we can't use searx...

[asciimoo]

Downgrading python to the previous (<=2.7.7) version solves the problem

fixed: d959cb1

[Cqoicebordel]

Confirmé.
(Youhou !!!)

[Glandos]

Woohooo! Partytime, I can use my own Searx again!
Thanks a lot for the (not so obvious) fix.

I had this same problem.

I was using gunicorn and moving away from gevent workers was the fix I went with.

I think this problem still persists at least with python 2.7.9(atleast, on heroku).
A workaround is to degrade to python version 2.7.8 or lower.

[avelino]

Is expected when resolves in Python version 2.7.9?

[FuqiangZhu]

I'm sorry.
