Channel doesn't shutdown

[Piotr Zolnierek]

I have this code below, where I am appending to a list in a channel, but sending -1 won't shutdown, and the app never exits. What am I doing wrong?

require channels

append(msg) =>

  -1                                  : @shutdown

  @print                              : print(mem[@values])

  *         | mem[@values] == Nothing : mem[@values] = [msg]

            | else                    : push(mem[@values], msg) 

  where

    mem     : channel_memory() 

  

main ->

  channel(@bucket, append, { @serialize: true}),

  @bucket.send(i) for i in [1..10],

  @bucket.send(@print),

  @bucket.send(-1)

Hmm, can you verify that it is not shutting down? i.e. try sending it a print command after the -1.

I suspect this may be because the global threadpool gets spun up and then is keeping main open as it is a daemon pool. In this case, a simple fix would be to call exit(0) instead of returning @shutdown.

Both are true... Printing after -1 works.

I added the exit to the event in the function, but that exits the app altogether, so that won't work if I just want to shutdown this one channel
