ipfs daemon shutdown command

[whyrusleeping]

It would be useful to have a command to be able to halt the daemon programmatically, either ipfs daemon stop or ipfs daemon shutdown.

This is not an issue, but more of a query. I am sorry if this is not the right forum for it but as its specific to this command I was hoping to get some help here.

I am working on something where I programatically start the ipfs node. I was trying to understand the shutdown code.

    Run: func(req *cmds.Request, re cmds.ResponseEmitter, env cmds.Environment) error {

	nd, err := cmdenv.GetNode(env)
	if err != nil {
		return err
	}

	if !nd.IsDaemon {
		return cmds.Errorf(cmds.ErrClient, "daemon not running")
	}

	if err := nd.Close(); err != nil {
		log.Error("error while shutting down ipfs daemon:", err)
	}

	return nil
},

The ipfs daemon is running in a separate process. How is this able to stop the same running node? Is there some way this cmdenv is able to share memory between processes?

I might have to go much deeper in code to understand this, so if anyone knows it on the top of their head I would really appreciate it!

As of ipfs version 0.8.0-dev, ipfs shutdown works, but ipfs help doesn't show it. People like me therefore keep trying ipfs stop, ipfs quit, ipfs terminate, ...

@jcomeauictx please file a new bug. It looks like this was never actually added to the help text.

Thanks, I'll pass for now. If I'm going to file a bug I might as well fix it and submit a pull request, and my plate is already overfull.
