If possible, include a link to a program on play.golang.org. This can be done with three files: http://play.golang.org/p/bxMjv7H1cw 1. create server.go and `go run` it 2. create race.go and race_test.go in a different directory 3. go test -race What happened? $ go test -race ================== WARNING: DATA RACE Write by goroutine 6: strings.(*Reader).Read() /usr/local/go/src/pkg/strings/reader.go:32 +0x6f go.(*struct { *strings.Reader; io.Closer }).Read() /usr/local/go/src/pkg/net/http/chunked.go:1 +0x90 net/http.(*bodyEOFSignal).Read() /usr/local/go/src/pkg/net/http/transport.go:1123 +0x278 io/ioutil.devNull.ReadFrom() /usr/local/go/src/pkg/io/ioutil/ioutil.go:151 +0xda io.Copy() /usr/local/go/src/pkg/io/io.go:349 +0x156 _/home/twmb/testing.request() /home/twmb/testing/race.go:16 +0x1aa Previous write by goroutine 7: strings.(*Reader).Read() /usr/local/go/src/pkg/strings/reader.go:32 +0x6f go.(*struct { *strings.Reader; io.Closer }).Read() /usr/local/go/src/pkg/net/http/chunked.go:1 +0x90 net/http.(*bodyEOFSignal).Read() /usr/local/go/src/pkg/net/http/transport.go:1123 +0x278 io/ioutil.devNull.ReadFrom() /usr/local/go/src/pkg/io/ioutil/ioutil.go:151 +0xda io.Copy() /usr/local/go/src/pkg/io/io.go:349 +0x156 _/home/twmb/testing.request() /home/twmb/testing/race.go:16 +0x1aa Goroutine 6 (running) created at: _/home/twmb/testing.RaceTest() /home/twmb/testing/race.go:28 +0x94 _/home/twmb/testing.TestRaceTest() /home/twmb/testing/race_test.go:8 +0x2b testing.tRunner() /usr/local/go/src/pkg/testing/testing.go:422 +0x10f Goroutine 7 (finished) created at: _/home/twmb/testing.RaceTest() /home/twmb/testing/race.go:29 +0xc3 _/home/twmb/testing.TestRaceTest() /home/twmb/testing/race_test.go:8 +0x2b testing.tRunner() /usr/local/go/src/pkg/testing/testing.go:422 +0x10f ================== PASS Found 1 data race(s) exit status 66 FAIL _/home/twmb/testing 1.028s What should have happened instead?
