[go-nuts] Type pointer pesistence

The garbage collector collects garbage (its name is accurate). Your
LiveObj is not garbage because there is a running goroutine holding a
reference to it.

So yes, you can assume this behavior, but it is a fundamental property and
I'm unsure why you need to ask. It implies something else is going on, at
least in your understanding.

Habits Rob, habits...
I was unsure how goroutines treat member functions, and their "self"
pointer lifetime. Thanks.

Hello, I Have the following code fragment. My question is: Can I assume
LiveObj is not garbage collected while it has running goroutine associated
with it, or it is just coincidence?

Thank you.

`package main

import "fmt"
import "time"
import "runtime"

type LiveObj struct {
}

func (self *LiveObj) run() {
for {
time.Sleep(1 * time.Second)
fmt.Println("Hello, LiveObj")
}
}

func main() {
fmt.Println("Hello, playground")
{
l := &LiveObj{}
go l.run()
}
runtime.GC()

time.Sleep(1 * time.Minute)
}`

Output:

`Hello, playground
Hello, LiveObj
Hello, LiveObj
.... (for 1 minute)

Program exited.`
