Skia Buildbots

Overview

Like the Chromium team, the Skia team uses buildbot to run continuous builds and tests.

Here is a link to our main status page: https://status.skia.org/

There are also Skia client, compile, Android, and FYI console pages for a detailed view of those results:

Architecture

The buildbot system consists of these elements: (see http://buildbot.net/buildbot/docs/current/manual/introduction.html#system-architecture for more detail)

  • builder

    • one repeatable build and/or test configuration on a given platform.
    • each builder maintains its own local checkout of the Skia repo
    • only one builder is running at any given time on any single buildslave; otherwise, different builders could interfere with each other's performance numbers

  • buildbot master

    • watches for new commits to land in the Skia repository (https://skia.googlesource.com/skia)
    • whenever a new commit lands, it tells buildbot slaves to start building and testing the latest revision
    • serves up status pages whenever anybody requests them

  • buildslave (or “buildbot slave”)

    • a process on a machine that builds and runs code as directed by the buildbot master
    • one or more builders run on each buildslave

  • build

    • one run of a particular builder, at a particular code revision

Status View

The status view shows a table with builders, grouped by test type and platform, on the X-axis and commits on the Y-axis. The cells are colored according to the status of the build for each commit: green indicates success, red indicates failure, light orange indicates an in-progress build, and white indicates that no build has started yet for a given revision. Commits are listed by author, and the branch on which the commit was made is shown on the very left.

For more detail, you can click on an individual cell to get a summary of the steps which ran for that build. You can also click one of the white bars at the top of each column to see a summary of recent builds for a given builder.
