net/http: log ServeContent errors reading from the content during Copy? #31932
func serveContent was used by docker distribution project,I get 'unexpect eof error 'when I pull image for registry server may be related the bad network(just 20mb bandwidth).I can'not find any error in registry server log,it alwayls return response complete and 200 http status code.so i found error in io.CopyN after debug,it just copy only part of entire content due to ceph( the regitry storage backend ) rst the connection(mayby slow network).
I found same issue in 9709 ,however ,If it's not worth the cost of adding return error,can add error in ResponseWriter.like this
