#2460 assigned enhancement

Build a plugin architecture

Reported by: dustin Owned by: sa2ajj
Priority: minor Milestone: 0.9.+
Version: Keywords: plugins
Cc: hithwen@…, rutsky.vladimir@…

Description (last modified by dustin)

It should be possible for users to add extra functionality to Buildbot by installing additional packages from pypi. The extra functionality should include

  • change sources
  • build steps
  • status plugins
  • web UI components
  • utility scripts (#1828)

The setuptools entry-points support can help here.

Once this is complete, long-term unmaintained code currently distributed with Buildbot should be moved to external projects (still in the Buildbot github organization) where it can be maintained - or not - by its users.

We should produce simple "hello-world" templates for each type of plugin, so that users have somewhere to start.


This project will involve understanding how Python packages are built, tested, documented, and distributed.

I did some coding in (documentation is still needed as well as some tests, though I have no clue how to provide mock data for pkg_resources).

Any candidates for "long-term unmaintained code"?

BitKeeper? is a decent example of long-term-unmaintained. Also, stuff from contrib/.

As for testing, if you moved the pkg_resources stuff into wrapper functions, you could mock out those functions. Does that help?

  • Type changed from project-idea to enhancement

For the record, the code (docs is a bit behind) is available in

In that PR utility scripts are not going to be implemented (that's gonna be next step together with one more utilty script to show plugins available for Buildbot).

There could be some nits for the documentation, otherwise I think it's complete.

The main part is done, the rest is not that major (and part of that activity is to review sub-tickets).
