The first part of the issue with the functional tests is that there's a trailing whitespace in the key of the map here (which was very obscure to find; note the "/trace "):

etcd/pkg/debugutil/pprof.go

Line 39 in 5161b74

m[HTTPPrefixPProf+"/trace "] = http.HandlerFunc(pprof.Trace)

It should be

m[HTTPPrefixPProf+"/trace"] = http.HandlerFunc(pprof.Trace)

After fixing that, there are still more test failures 😅

LGTM. Thanks, Henry.

Thanks for digging into this @ivanvc !!

It's actually the only part besides the linter issue which blocked the CI!

Yes, I realized later that some local changes were the cause of my other errors 🙊
