Google Summer of Code 2018 Final Report: Automatic Builds with Clang using Open Build Service

14 August 2018

Project Overview Debian package builds with Clang were performed from time to time through massive rebuilds of the Debian archive on AWS. The results of these builds are published on clang.debian.net. This summer project aimed to automate Debian archive clang rebuilds by substituting the current clang builds in clang.debian.net with Open Build System (OBS) builds. Our final product consists of a repository with salt states to deploy an OBS instance which triggers Clang builds of Debian Unstable packages as soon as they get uploaded by their maintainers.

Some notes on the OBS Documentation

This is my fourth post of my Google Summer of Code 2018 series. Links for the previous posts can be found below: Post 1: My Google Summer of Code 2018 project Post 2: Setting up a local OBS development environment Post 3: Running OBS Workers and OBS staging instance Open Build Service Manuals OBS provides several manuals on their web site, including an admin and a user guide. Since I needed to travel to an academic conference last week (too many hours in airplanes), I took some time to read the full OBS documentation to have a better understanding of the tool we have been deploying.
