# antifreeze

antifreeze is a package that detects goroutines that have been waiting for too long.

**Warning: this package is alpha and may not work as intended.**

You can exclude functions that may block forever with `antifreeze.Exclude` and `antifreeze.ExcludeNamed`.

Example program that will panic ~1min after you have made a request to it.

``` go

package main

import (

	"fmt"

	"net/http"

	"time"

	"github.com/egonelbre/antifreeze"

)

func init() {

	antifreeze.SetFrozenLimit(1 * time.Minute)

}

var ch = make(chan int)

func runner() {

	antifreeze.Exclude()

	<-ch

}

func main() {

	go runner()

	http.Handle("/", http.HandlerFunc(index))

	http.ListenAndServe(":8000", nil)

}

func index(w http.ResponseWriter, r *http.Request) {

	fmt.Println("R:", r)

	<-ch

}

```
