I tried to remove this earlier and it caused issues: #7872
I think the case this protects against is having opentracing installed, but disabled via the config.

Did you also remove the explicit scope.span.set_tag(...)?

In particular
start_active_spanreturns a scope, which is meant to be a context manager that returns itself, but it didn't. This fixes that.We also clean some other stuff up, we don't actually need to set
error=Truetag manually, that happens for us, and there is no point having the if opentracing guard there given we both have it up a layer andstart_active_spanreturns a null context manager anyway.Broke in #7872
