Bug 188533 – [ews-build] Allow * as platform for builders and workers

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Aakash Jain]

When a worker (e.g.: webkit-misc) or builder (e.g.: Bindings-tests) do not need a very specific platform, we use * as the platform. However, loadConfig has a check to ensure that the platform matches for worker and platform. This prevents bot with * as platform to connect to multiple queues, or a builder with * as platform to connect to a worker with a specific platform.

We should allow the case when either worker or builder has * as platform, but the other has a specific platform. This would also help in testing (by allowing one bot to be used for testing multiple queues).

I'm not sure what our supported configurations might be, so my initial thought is to break this logic...

Is it possible we would have a configuration where either worker['platform'] was * OR builder['platform'] = * but not both?
In that case, would we prefer to do something like
and (worker['platform'] != '*' or builder['platform'] != '*')

Yes, Recently I have been using such a configuration on https://ews-build.webkit-uat.org, especially because I have limited bots for testing and I want a bot to process builds from multiple queues (both mac and ios). In this case worker['platform'] is * since worker can connect to multiple queues. builder['platform'] remains ios/mac accordingly. e.g.: https://bugs.webkit.org/show_bug.cgi?id=194304

This 'if' is to detect an error case, so it should be 'and' of all three conditions. The one in the patch has been working fine in my testing for a while.
