Storing a pointer to a stack value (Golang)

由 大憨熊 提交于 2021-01-27 06:33:12
问题 I'm trying an experiment in Go, to see what happens if I store a pointer to a variable on the stack, and then access that variable after the original variable has left scope. package main import "fmt" var p chan bool; // a temp struct type v struct { a int } func another_thread(vx *v) { // this code should be executed after a() returns so vx should be a pointer to a value that's no longer on the stack fmt.Printf("another_thread(): %p\n", vx); vx.a = 4 // am I updating a dangling pointer that

How to implement server side timeouts? (Confused about http.Server timeouts)

由 不羁的心 提交于 2021-01-27 06:32:32
问题 I'm trying to implement server-side timeouts for my service. If the request takes longer than X seconds, the server should return 503 Service Unavailable. I know that this can easily be accomplished by wrapping all of my endpoints in http.TimeoutHandler, but I'm confused why this isn't being done automatically by the Timeout fields of http.Server Here is a trivial example that I am using for testing. If I cURL or POSTman this server, it hangs forever, rather than the 5 seconds I expect.
