Go http标准库中的内存泄漏？

Go http标准库中的内存泄漏？

从

pprof

您在注释中提供的堆中，看来您正在通过

gorilla/sessions

和

gorilla/context

（将近400MB）泄漏内存。

请参阅以下ML线程：[https](https://groups.google.com/forum/#!msg/gorilla-

这是一个泄漏速度非常快的版本：

package mainimport (    "fmt"    // "github.com/gorilla/context"    "github.com/gorilla/sessions"    "net/http")var (    cookieStore = sessions.NewcookieStore([]byte("cookie-secret")))func main() {    http.HandleFunc("/", defaultHandler)    http.ListenAndServe(":8080", nil)}func defaultHandler(w http.ResponseWriter, r *http.Request) {    cookieStore.Get(r, "leak-test")    fmt.Fprint(w, "Hi there")}

这是一个清理并具有相对静态的RSS的示例：

package mainimport (    "fmt"    "github.com/gorilla/context"    "github.com/gorilla/sessions"    "net/http")var (    cookieStore = sessions.NewcookieStore([]byte("cookie-secret")))func main() {    http.HandleFunc("/", defaultHandler)    http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))}func defaultHandler(w http.ResponseWriter, r *http.Request) {    cookieStore.Get(r, "leak-test")    fmt.Fprint(w, "Hi there")}
