If we're testing through dist, we're testing the implementation of Go, so we're interested in any package failing with potential runtime issues. In these cases, we'd like to have as much relevant detail as possible, but currently runtime stack frames and goroutines are suppressed due to the default GOTRACEBACK setting. So, try to set GOTRACEBACK to system if it's unset. Check if it's unset first so we don't override the user asking for a lower or higher level. This change was brought up in the context of #45916, since there's an apparent deadlock (or something!) in the runtime that appears when running other code, but it's difficult to see exactly where it's blocked. However, this change is very generally useful. This change also runs scripted tests with GOTRACEBACK=system, upgrading from GOTRACEBACK=all. Often, script tests can trigger failures deep in the runtime in interesting ways because they start many individual Go processes, so being able to identify points of interest in the runtime is quite useful. For #45916. Change-Id: I3d50658d0d0090fb4c9182b87200d266c7f8f915 Reviewed-on: https://go-review.googlesource.com/c/go/+/316469 Trust: Michael Knyszek <mknyszek@google.com> Trust: Bryan C.
