Snapd API and wait

jocado · June 10, 2021, 6:02pm

Hi,

the snapd command has the wait arg.
Is it possible to use wait in the snapd API, with both the snapd and snapctl sockets ?

Or is wait just a cli wrapper for API polling in the background ?

Thanks !

Cheers,
Just

Indeed, wait is just a loop calling the /v2/snaps/system/conf endpoint:

	for {
		conf, err := x.client.Conf(snapName, []string{confKey})
		if err != nil && !isNoOption(err) {
			return err
		}
		res, err := trueishJSON(conf[confKey])
		if err != nil {
			return err
		}
		if res {
			break
		}
		time.Sleep(waitConfTimeout)
	}
