I'm not sure if it's related to this issue, or a separate issue, but there haven't been any plan9 builder results for any of the subrepos recently. I.e., https://build.golang.org/?repo=golang.org%2fx%2ftools has no entries for plan9/386, despite the configuration suggesting there should be:

https://github.com/golang/build/blob/0261b66eb04541491e09bffe4a6d212f9a76675b/dashboard/builders.go#L881

Yes, there is currently an issue happening on the plan9/386 builder. It started on 2019-02-01 approximately. I'll investigate.

What's the status here? I haven't seen a plan9/386 build pass in a long time.

I'm currently investigating an issue with the runtime/trace test running out of memory on the plan9/amd64 builder.

The issue on the plan9/386 builder is different. I've not been able to reproduce it yet, since it runs successfully on my 386 machines at home. I'll have to try on GCE.

There was something very odd on the plan9/386 builder during the past few months. The builder started to fail in early February, then after 4 weeks of failure, the tests passed successfully in early March during 8 days, then it started to fail again.

I'm going to have to stop the plan9 builders. It's a waste of resources & distracting to have them always building and resulting in crashes, loops, timeouts, or other failures.

Could you try to disable the runtime/trace tests? It may be the same issue I'm currently encountering on plan9/amd64.

After a few more tests, it seems unlikely that the issue may be caused by the runtime/trace test. I'm suspecting something else. Please hang on.

I ran all.rc in a loop on GCE (n1-highcpu-4) during the night and the tests always passed successfully, except fixedbugs/issue30908.go, which is a recent issue (issue #31503).
I'm still investigating.

The builders don't run all.rc or all.bash, etc. They run make.ext and then use go tool dist test to run the tests. Maybe something's broken with Plan 9's subprocess handling.

Could you give me a builder key so I could run the plan9/386 buildlet on my side and debug it?

You can use the buildlet & debugnewvm (perhaps modified) to test it.

I figured how to use debugnewvm, then ran the plan9/386 build. The tests passed successfully, except the issue30908 test (issue #31503). Now, I'm puzzled.

$ go run debugnewvm.go -host host-plan9-386-gce -run-build plan9-386

debugnewvm doesn't quite do what the coordinator does, either. It's much closer and is useful for debugging, but it's not 100% the same (yet?). It still runs all.rc instead of running each test separately. I wonder if that's related. I can't think of anything else.

@0intro, sure, send a CL to dashboard/builders.go adding the new host type & builder (host-plan9-386-0intro and plan9-386-0intro) and I'll send you the host key.
