Azure DevOps: Python Wheels

This is the third post in a series about Azure DevOps. This one is about making Python wheels. If you want to play nice with Python users, or you have a complex build, this will make your package far more accessible to users. They are faster to install and to use and more secure. We will quickly cover making universal wheels, then we will move on to fully compiled binaries, including C++14, manylinux2010, and other hot topics. This series was developed to update the testing and releasing of Python packages for Scikit-HEP. The results of this tutorial can be seen in the boost-histogram repository, under the .ci folder.

Azure DevOps: Releases

This is the second post in a series about Azure DevOps. This one is about release pipelines; if you use Azure to build packages (like binaries, etc.), how do you push them to a final endpoint? In this example, we will be building a simple pure Python package, and pushing the result to Test-PyPI. You can adapt it to your situation, however. The third post will cover building Python binaries. This series was developed to update the testing and releasing of Python packages for Scikit-HEP. Several of the projects in SciKit-HEP are using release pipelines, include boost-histogram and Particle.

Azure DevOps: Introduction

Continuous Integration (CI) is fantastic for software development and deployment. One of the newest entries into the CI market1 is Microsoft’s Azure DevOps. Their Open Source support is impressive; it is likely part of the recent push2 by Microsoft to be more Open Source friendly. Open Source projects get 10 parallel builds, unlimited build minutes, 6 hour job timeouts, and incredibly fast jobs on macOS, Linux, and Windows, all via a single platform. Quite a few major projects3 have been moving to Azure since the initial release in December 2018. The configuration of DevOps is second only to GitLab CI in ease of use and possibly the most expressive system available. The multiple pipeline support also scales well to complicated procedures.

This is the first in a series of posts covering an introduction to setting up projects in Azure DevOps, developed to update the testing and releasing of Python packages for Scikit-HEP, a project for a coherent High Energy Physics Python analysis toolset. The second post covers release pipelines, and the third covers building binary Python packages using DevOps.
