Migrating Python.org to Buildbot 9 and Python 3 by Craig Rodrigues

When developers make changes to core CPython, a set of scripts which builds the core Python code and runs tests on Linux, Windows, FreeBSD, and other platforms happens. These scripts run under a framework called Buildbot ( https://buildbot.net ).

For quite some time, Python was using an older version of Buildbot which only ran under Python 2.

This talk will cover my efforts to port the Buildbot to Python 3, and how I worked with the Python Buildbot team to help them upgrade their buildbot cluster at ( http://buildbot.python.org/all/ ) so that they use Buildbot running under Python 3.

Bio:
Craig Rodrigues is a software engineer who currently works as a QA automation engineer at an analytics startup. Originally from Toronto, Canada, Craig lived in Boston for many years before settling in the Bay Area 10 years ago. Craig is an avid open source contributor, and has contributed to such projects as Twisted, Buildbot and FreeBSD. Craig is passionate about using automation (especially with Python) to improve efficiency and build better software.

Main talk (~30 mins + Q&A)

Python 3 at Lyft
Lyft is a big fan of Python. It’s quite common for services to utilize NumPy, Pandas, and PuLP to serve requests via Flask, Gevent, and Gunicorn. We use SciPy to fight fraud, we use Salt to provision hosts. We’ve got hundreds of Python microservices totalling millions of lines of code and like most companies we were faced with a decision about what to do with Python 2. Do we push forward with the upgrade to Python 3 or do we explore re-writing in other languages? Lyft has been successfully migrating services over to Python 3 for the past 5 months. We've gotten the process of upgrading down to around a week worth of work per service through improvements in static analysis and building groundswell of support. In this talk we'll be sharing how we accomplished that and how you can use these same tools to make getting to Python 3 easy!
