The Butler and the Snake - Continuous Integration for Python

Continuous Integration is a software development practice where members of a team integrate their work frequently, leading to multiple integrations per day. Each integration is verified by an automated process (including tests) to detect integration errors as quickly as possible.

This talk will introduce the basic principles for building an effective Continuous Integration system for Python-based projects. It will present the lessons learned from building a Jenkins-based CI system for an Open Source project with a distributed team of more than 340 core developers that ranks among the top 2% of all open source projects worldwide (Plone).
