simple process spawn() seemingly failing

[stochastic-thread]

a = spawn(fn -> receive do :arthur -> IO.puts(:hey) end end)
send a, :arthur

Erlang version: 19 Elixir version: 1.3.2 Notebook version 4.2.3

When I try to execute the above two lines, the notebook server prints the following out in the logs

2016-11-25 18:28:49.694 [error] Process #PID<0.201.0> raised an exception
** (ErlangError) erlang error: :terminated
    (stdlib) :io.put_chars(#PID<0.200.0>, :unicode, ["hey", 10])

When I try locally in an iex session, it works fine. Any idea what's the issue here? Does it not know that the notebook is stdout or something (just a guess...) ? I am pretty sure I've been able to do this previously, last time I messed around with IElixir

Hi @arthurcolle, can you test it one more time? I've fixed support for younger elixir/otp versions.

[pprzetacznik]

@arthurcolle I'm abandon supporting of 1.3.2 version of elixir. Could you try this with the newer version and report the problems as another ticket if needed?

thanks I'll check this out depressing this was two years ago feels like last week

[pprzetacznik]

@arthurcolle same here. I see this problem still occurs. I'll take a look at this closer.

@arthurcolle funny, it works fine when executed as two separated statements but not as one statement.

[stochastic-thread]

@pprzetacznik interesting...i vaguely recall observing that behavior any insight into elixir limitations that would/could cause this?

I am facing the same problem and I made it kind of work with :stderr

a = spawn(fn -> receive do :arthur -> IO.puts(:stderr, :hey) end end)
send a, :arthur

Maybe is something related with the :standard_io outside the notebook process??
