Hello,

At the beginning - welcome everyone, as this is my first post here. I'm not=
 an active Python developer now, but I have general knowledge of the langua=
ge.=20

I'm trying to use locust (http://locust.io/) to run load test of one site w=
e're developing. Everything was running nice and smooth until we switch the=
 servers to use SNI. SNI is not officially supported in python 2.7.5 but Lo=
cust doesn't work on python3 as it uses gevent which AFAIK are supported fo=
r python2 only. I finally managed to run our scripts on local Ubuntu after =
upgrading python to 2.7.8 from utopic repository but I can't replicate the =
same on target CentOS where the scripts are supposed to be executed. I trie=
d compiling python from http://www.python.org/ftp/python/2.7.8/Python-2.7.8=
.tar.xz, I even tried unpacking sources of Ubuntu python2.7 package (from h=
ttp://se.archive.ubuntu.com/ubuntu/pool/main/p/python2.7/python2.7_2.7.8.or=
ig.tar.gz), patching them with TLS1_1 and TLS1_2 support from  https://bugs=
.python.org/file30761/python-2.7.5-tls1.1-and-tls1.2.patch) and still no lu=
ck. I do monkey patch in Locust startup file according to http://stackoverf=
low.com/a/19477363 (otherwise it wouldn't work on Ubuntu as well) but still=
 I get error stack as attached below. I also checked with pip list that all=
 python packages have the same versions on both systems. Any idea what I'm =
missing on the target load test system which I have in Ubuntu?=20

Regards,
Reddy
