Buildbot

Buildbot Overview

We use Buildbot for automated building and testing of Fast Downward. The Buildbot master for Fast Downward is located at http://buildbot.fast-downward.org/.

Buildbot Configuration

Our Buildbot uses eight workers with different operating systems, compilers, and LP solvers:

• Ubuntu 16.04, GCC 5.4, CPLEX 12.8
• Ubuntu 16.04, GCC 5.4, no LP solver
• Ubuntu 18.04, GCC 8.2, CPLEX 12.8 (We call this worker the foreman and use it for builds that only need to run on a single worker)
• Ubuntu 18.04, GCC 8.2, no LP solver
• Ubuntu 18.04, clang 3.9, CPLEX 12.8
• Ubuntu 18.04, clang 3.9, no LP solver
• Windows 7, VS 2017, CPLEX 12.8

• macOS Sierra, AppleClang 8.0.0, no LP solver

On every commit on the default branch, we run the following tests

• A style check of the code (only on the foreman). If these tests fail, the others are not run.
• Build tests on all workers. These are slightly different for the different operating systems
  • All Linux workers

    • 32-bit tests: we test an incremental build of the release32 configuration, followed by clean builds of the release32 and debug32 configurations. We then run all our code tests.

    • 64-bit tests: if the 32-bit builds are successful, we test incremental builds of the release64 and debug64 configurations.

    • Autodoc: if the 32-bit builds are successful, we also update our documentation in this wiki. This is run only on the foreman.
  • Windows

    • Similar to the Linux setup, we start with in incremental build of the configuration release32nolp (32-bit configuration, ignoring the installed LP solver) followed by clean builds of release32nolp and debug32nolp. We then test clean builds of releasenative and debugnative, that use the native 64-bit build with an LP solver. We do not run any code tests on Windows.

  • macOS

    • We test an incremental build of the release32 configuration, followed by clean builds of the configurations release32, debug32, release64, and debug64. We then run exit code tests and test on some benchmark tasks. We do not include translator tests as on Linux, because we don't have a running Python3 installation.

In addition to the tests that run on every commit, we run a nightly and a weekly test, that both run some default configurations on the first problem of Gripper and Miconic to check for any performance regressions. We also have a builder that can only be triggered manually and recreates the baseline for these nightly/weekly tests.
