bcmills · 2023-06-30T16:26:44Z

I wonder if this is related to #18717. Do we know if cgo_yield is non-nil on darwin when the race detector is enabled?

bcmills · 2023-06-30T16:31:06Z

The answer as of https://go.dev/cl/451055 seems to be no.

So, that's my theory: the TSAN runtime is deferring signals as described in #18717, but the workaround added to the runtime package for #18717 is no longer in effect because runtime/race/race.go is no longer used on darwin, which causes runtime/cgo not to be linked in, which causes _cgo_yield to be nil.

bcmills · 2023-06-30T16:33:25Z

One possible fix, in the spirit of https://go.dev/cl/451055, would be to have runtime/race provide a libc-but-not-cgo definition of _cgo_yield.

gopherbot · 2023-06-30T16:51:57Z

Change https://go.dev/cl/507356 mentions this issue: runtime/pprof: use testenv.Command in tests instead of exec.Command

bcmills · 2023-06-30T16:59:47Z

@cherrymui notes:

I think C TSAN intercepts signals but the Go race detector doesn't (when it bundles TSAN it doesn't include the signal interceptor code). So for non-cgo build it shouldn't matter?

But I wonder: since we're linking against libc on macOS, do we use our bundled TSAN implementation, or the one provided by the system C toolchain? 🤔

cherrymui · 2023-06-30T17:24:02Z

I think we use the bundled TSAN implementation from the race syso files. I don't think the libc we use contains TSAN.

If the test is about to time out, testenv.Command sends SIGQUIT to the child process. The runtime's SIGQUIT goroutine dump should help us to determine whether the hangs observed in TestCPUProfileWithFork are a symptom of #60108 or a separate bug. For #59995. Updates #60108.
