Description

Graceful is a Go 1.3+ package enabling graceful shutdown of http.Handler servers.

Behaviour

When Graceful is sent a SIGINT or SIGTERM (possibly from ^C or a kill command), it:

1. Disables keepalive connections.
2. Closes the listening socket, allowing another process to listen on that port immediately.
3. Starts a timer of timeout duration to give active requests a chance to finish.
4. When timeout expires, closes all active connections.
5. Closes the stopChan, waking up any blocking goroutines.
6. Returns from the function, allowing the server to terminate.

Notes

If the timeout argument to Run is 0, the server never times out, allowing all active requests to complete.

If you wish to stop the server in some way other than an OS signal, you may call the Stop() function. This function stops the server, gracefully, using the new timeout value you provide. The StopChan() function returns a channel on which you can block while waiting for the server to stop. This channel will be closed when the server is stopped, allowing your execution to proceed. Multiple goroutines can block on this channel at the same time and all will be signalled when stopping is complete.

Usage

package main

import (
	"github.com/kataras/iris"
	"gopkg.in/tylerb/graceful.v1"
	"time"
)

func main() {
	api := iris.New()
	api.Get("/home", func(c *iris.Context) {
		c.Write("Hello from the /home")
	})

	graceful.Run(":8080", 10*time.Second, api)
}
