Stop polling server for playlist.

[vrtisworks]

I am writing a script that will go ask a server for the next song to play.

It works fine, as long as the http server is up and running when I start up liquid soap. If the server is not up, or crashes, there doesn't seem to be a way to tell Liquidsoap to quit trying to load the playlist. I put a little timer on the back for testing, and even after I issue the source.shutdown, the log still shows that Liquidsoap is trying to ask the server for a file.

Can somebody tell me what I'm doing wrong? Or how I can start and stop Liquidsoap polling the server for the file?

I am running 1.0.1 on a Raspberry Pi if that makes a difference.

Thanks.

#!/usr/bin/liquidsoap
#
#Put the log file in some directory where
#you have permission to write.
#set("log.file.path","./liquidtesting.log")
set("log.file",false)
#Print log messages to the console,
set("log.stdout", true)
#Use the telnet server for requests while testing
set("server.telnet", true)

#We have a dummy/blank source/output to keep things running
blanksource = blank(id='blanksource')
output.dummy(fallible=false, blanksource);

#A few functions/stuff we need to control the player
#we need a boolean reference to set (true|false), initially false
player_on = ref false
thelist = ref playlist("")

def turn_player_on()
    #Only turn it on if it is currently off
    log("Turning player on")
    if !player_on == false then
        #set the flag it is on
        player_on := true
        #create the playlist and then output it to the speakers.
        pl=playlist(id="url_list", mode="normal", reload=1, reload_mode="rounds","http://localhost:3000/getNextSongFileName")
        thelist := pl
        #radio=fallback(id="the_radio",track_sensitive=false,
        #    [pl,blanksource])
        myout =  output.alsa(id='localAudio', device="hw: Set",pl)
    end
end

#A function to create 'thelist' playlist when we have node all up and ready
def turn_player_off()
    #Only turn it off if it is already on
    log ("Turning Player off")
    if !player_on == true then
        #set the flag it is off
        player_on := false
        #Shutdown the node source
        source.shutdown(!thelist)
        log (source.id(!thelist))
    else
        shutdown()
    end
    #add_timeout expects a function that will return a float
    0.5
end

turn_player_on()
add_timeout(0.5,turn_player_off)

Apparently the trick is that you have to shutdown BOTH the playlist AND the output. Then the playlist tries one more time and gives up.
