The actions can be "enable", "disable", or "auto". If the action changes the status, a message will be broadcast over the network. Note that enabling / disabling a channel using this command ONLY affects what's advertised over the network. For example, disabling a channel using this command does not close it. If a channel is manually disabled, automatic / background requests to re-enable the channel will be ignored. However, if a channel is manually enabled, automatic / background requests to disable the channel will succeed (such requests are usually made on channel close or when the peer is down). The "auto" action restores automatic channel state management. Per the behavior described above, it's only needed to undo the effect of a prior "disable" action, and will be a no-op otherwise.`, ArgsUsage: "funding_txid [output_index] action", Flags: []cli.Flag{ cli.StringFlag{ Name: "funding_txid", Usage: "the txid of the channel's funding transaction", }, cli.IntFlag{ Name: "output_index", Usage: "the output index for the funding output of the funding " + "transaction", }, cli.StringFlag{ Name: "action", Usage: `the action to take: must be one of "enable", "disable", ` + `or "auto"`, }, }, Action: actionDecorator(updateChanStatus), } func updateChanStatus(ctx *cli.Context) error { ctxc := getContext() conn := getClientConn(ctx, false) defer conn.Close() if ctx.NArg() == 0 && ctx.NumFlags() == 0 { _ = cli.ShowCommandHelp(ctx, "updatechanstatus") return nil } channelPoint, err := parseChannelPoint(ctx) if err != nil { return err } var action routerrpc.ChanStatusAction switch ctx.String("action") { case "enable": action = routerrpc.ChanStatusAction_ENABLE case "disable": action = routerrpc.ChanStatusAction_DISABLE case "auto": action = routerrpc.ChanStatusAction_AUTO default: return errors.New(`action must be one of "enable", "disable", ` + `or "auto"`) } req := &routerrpc.UpdateChanStatusRequest{ ChanPoint: channelPoint, Action: action, } client := routerrpc.NewRouterClient(conn) resp, err := client.UpdateChanStatus(ctxc, req) if err != nil { return err } printRespJSON(resp) return nil }
