Restore availability of pprof in the debug server
What does this MR do?
Restore pprof
debugging endpoint that was removed by mistake when workingon !934 (merged)
Why was this MR needed?
With !934 (merged) we've changed how the debug server is started. It can be seen at !934 (diffs):
+ mux := http.NewServeMux()
+
go func() {
- log.Fatalln(http.Serve(listener, nil))
+ log.Fatalln(http.Serve(listener, mux))
}()
Instead of relaying on the http.DefaultServeMux
(which is used when
http.Serve(listener, nil)
is called), we're creating our own ServeMux
which next is used for handling requests.
Unfortunately this breaks automatic registration of pprof handlers,
which in net/http/pprof
's init()
are using http.Handle()
, which
registers the handlers in http.DefaultServeMux
.
Are there points in the code the reviewer needs to double check?
Does this MR meet the acceptance criteria?
