builders.py should autogenerate the list of builders from the buildbot json

• Component: Tools / Tests
• Status: RESOLVED FIXED

We shouldn't need to manually keep this list up to date. We should grab the list of builders from the buildbot json and filter out the non-testers. The flakiness dashboard does this and it requires almost no manual maintenance. See requestBuilderList in http://trac.webkit.org/browser/trunk/Tools/TestResultServer/static-dashboards/builders.js#L134.

The only tricky bit here is that builders.py has extra metadata that we'd have to infer from the buildername, specifically port_name and specifiers. Actually, now that I think about this more, is this the only place we map builder name to port name? Maybe we do need this list after all. :( Dirk or Adam, WDYT?

While we're at it we probably want to improve the naming so that it's clear that this list only contains testers.

Yeah, I dont know how you'd grab that data otherwise. I suppose you could then fetch individual results.json from the bots and extract the port name from that, but I'm not convinced it's worth it.

This list doesn't change very often; I think trying to automatically generate it sounds like it's more trouble than it is worth.

Yeah, I just didn't think through this very clearly I think. Feel free to reopen if you think of a way to simplify maintaining this list.
