Currently the buildbots are configured with a couple of giant JSON files.

This makes it extremely easy to edit the config for the wrong bot as you could have just paged up or down to far.

Because so much of the JSON file is also repeated between the bots it also makes the diffs problematic as they can frequently apply to multiple locations inside.

Having everything in the same file also makes it impossible to diff the config between two builders.

It would be much easier if the JSON file was split into one per bot. IE Something like;

  testing/buildbot/chromium.webkit/WebKit Linux Trusty.json
  testing/buildbot/chromium.webkit/WebKit Linux Trusty (dbg).json

The only real complication is the special characters (like brackets) in some builder names.

You could then do things like;

 diff "testing/buildbot/chromium.webkit/WebKit Linux Trusty.json" "testing/buildbot/chromium.webkit/WebKit Linux Trusty (dbg).json"

I know there are plans to replace / fix / modify this file in some way. However, this would be a relatively small change which would drastically improve the editing experience here.

As an example, I made a couple of mistakes editing this file last night while deploying layout tests on swarming that were not caught by myself or reviewers. I doubt I'm the only person who will end up making mistakes like this before these files are replaced.
