Advantages of Jenkins over Buildbot

​Jenkins and ​Buildbot are both continuous-integration servers. WebKit currently uses Buildbot at ​http://build.webkit.org/. This page lists some advantages switching to Jenkins would bring.

Annotating build failures

As described in ​bug 59527, we'd like to be able to annotate build failures to show whether someone is working on them. Jenkins's ​Claim plugin would let us do just that.

Build times

Jenkins has built-in support for tracking the length of the build over time and graphing it.

Code coverage statistics

Jenkins's ​Cobertura plugin combined with ​coverage.py would allow us to track code coverage statistics for our Python unit tests. See ​an example from Apache's Jenkins server.

Determining when a test started failing

Jenkins has built-in support for determining when a test started failing, and will link you right to that build. See ​an example from Apache's Jenkins server. The "Age" column contains links to the first build in which each test failed.

Graphs of test failures over time

Jenkins has built-in support for tracking the number of failing tests over time and graphing it. See ​an example from Apache's Jenkins server.
