https://go.dev/wiki/SlowBots currently says:

For the main Go repository, the terms after TRY= can also be:

  • x/repo, where repo is one of the golang.org/x repositories whose tests should be executed. This runs a default builder for the given repo (linux-amd64 as of writing).
  • x/repo@builder, where repo is as above, and builder is a builder name from the builder list. This runs the specified builder for the given repo. For example, x/sys@linux-arm64-aws.

I attempted to use that functionality in https://go-review.googlesource.com/c/go/+/403694/1#message-384468da277d8d207745408ee312e594834c0c3b, with the line

TRY=longtest,windows-amd64-longtest,x/sys@longtest,x/sys@windows-amd64-longtest

I expected that that would run the usual TryBots, plus longtest and windows-amd64-longtest SlowBots for the go repo, plus longtest and windows-amd64-longtest SlowBots for the x/sys repo.

However, the x/sys SlowBots were not included in that run, and the Coordinator didn't reply with any kind of error message for the TRY= line.

I tried again in https://go-review.googlesource.com/c/go/+/403694/1#message-e384c689409e2701273d9ea9e87a132aee29c93b with just

TRY=x/sys@windows-amd64-longtest

but that doesn't seem to have worked either. This is making it difficult to verify the fix for #52666.

The reason for this is likely that windows-amd64-longtest is not a TryBot, which is currently required:
https://cs.opensource.google/go/x/build/+/master:cmd/coordinator/coordinator.go;l=1312;drc=993f2c6f22a69963d73f42c2712c601bff8c3939

Unfortunately, it is only surfaced in logs, and not in a message back to the CL.

This actually came up in chat recently: I think we don't actually need to impose this restriction.

Reopening until the coordinator is deployed.

As a follow-up, I'll try to include more details about parsing failures / invalid slowbots in the starting message.

I'll redeploy coordinator with this change after https://farmer.golang.org/#remote reaches 0 active gomote sessions.
