Tests sporadically timing out on 1.11

[christiangnrd]

I was able to reproduce on main. For a CI run that fails in this way, see https://buildkite.com/julialang/metal-dot-jl/builds/935#018ec983-4e76-42ab-bc96-fb795c07e721.

I can't reproduce this locally. Let's see if #330 reveals anything.

Local stacktraces from main (not #321).

Hmm, that's not terribly useful. It looks like its stuck without hitting a yield, so we don't get a backtrace for the active tasks. Could you maybe do so manually from LLDB by calling jl_print_task_backtraces(0)? For that, maybe get rid of the kill and replace it with a @show pid and sleep, or something like that.

[christiangnrd]

I'm not sure I did exactly what you were looking for but I got something.

[maleadt]

That is the correct output, however seeing the remotecalls in there I think you attached to the parent process, and not the process that actually timed out (we spawn multiple processes during testing).

You can find out the PID of the child process in htop, or by logging it here:

Metal.jl/test/runtests.jl

Lines 245 to 247 in 7042281

	pid = remotecall_fetch(getpid, wrkr)
	timer = Timer(480) do _
	@warn "Test timed out: $test"

. However, for that logging to be useful (i.e., the child process staying alive after the log message for you to attach) you'd need to disable the kills below.

I'd look into this myself but so far haven't been able to reproduce...

[christiangnrd]

I think this is the right thing. I've never used lldb before but I found JuliaLang/julia#47928 which has a usage example.

[maleadt]

I haven't seen this recently anymore, maybe this was a bug in Julia?

[christiangnrd]

Maybe? It happened with 1.11 beta1 though so I don’t know what would have changed for it to stop happening.

[christiangnrd]

Somewhat related but do you know why testing time in 1.11 is ~1.5x the 1.10 time?

[christiangnrd]

Closing as the recent sporadic failures seem different.
