# Python 3 Upgrade for Django Droplet
# Will update the "Django on 14.04" Digital Ocean image.
# Run as root.

# Grab psycopg2 and pip
apt-get install python3-pip python3-psycopg2

# Remove the Python 2.7 version of gunicorn, so we can...
pip uninstall gunicorn

# Install the Python 3 version of gunicorn, and a couple of dependencies.
pip3 install gunicorn tornado django
# Sadly, at time of writing, gevent isn't Python 3 compatible... But tornado is!
# So, switch them out with a little sed magic
sed 's/worker_class = '\''gevent'\''/worker_class='\''tornado'\''/' /etc/gunicorn.d/gunicorn.py -i.orig

# Restart gunicorn to make the changes take effect...
service gunicorn restart

# And we're good!
