Closed
Description
This program runs correctly in Go 1.5: it exits 0. In Go 1.6 it dies because it detects the ReadAll succeeding despite having called Body.Close.
This was masking some bad code in go get but it's a real problem in its own right: Read after Close should fail.
package main
import (
"io/ioutil"
"log"
"net/http"
)
func main() {
resp, err := http.DefaultClient.Get("https://bazil.org/fuse/fs/fstestutil?go-get=1")
if err != nil {
log.Fatal(err)
}
resp.Body.Close()
data, err := ioutil.ReadAll(resp.Body)
if len(data) != 0 || err == nil {
log.Fatalf("ReadAll returned %q, %v", data, err)
}
}
