Initial step

The idea is simple. Let's say you have your svn repository at svn://svn.awesomefork.com/repo and you want to put your scripts in /trunk/tools/build.

Master

Create a build_internal directory that you can fetch with gclient; Create a master at this directory: svn://svn.awesomefork.com/repo/trunk/tools/build/masters/master.awesome. Then it's as you prefer. Either create a DEPS file or configure 2 solutions in gclient or simply sync manually with svn update.

Change the DEPS file for:

deps = {
  "build":
    "http://src.chromium.org/chrome/trunk/tools/build",
}

Slave

Copy the directory http://src.chromium.org/chrome/trunk/tools/buildbot/slave/ to svn://svn.awesomefork.com/repo/trunk/tools/buildbot/slave.

Create 

deps = {
  "build":
    "http://src.chromium.org/chrome/trunk/tools/build",
}

Private settings

Put private settings in build_internal/site_config/config.py.

Now what?

So you're set!
  • You can add other dependencies or use deps_os = { } to add OS specific dependencies to the DEPS files if you use DEPS files.
  • You may want to copy the whole directories or fetch specific revision with @revision notation in the .gclient files.

Run your fork

Master

gclient config svn://svn.awesomefork.com/repo/trunk/tools/build_internal
gclient sync
cd build_internal/master/master.awesome
make restart

Slave

gclient config svn://svn.awesomefork.com/repo/trunk/tools/build_internal
gclient sync
cd master
make restart

Maintain it

Now you only need to maintain your infrastructure.
