GC Operation on Unregistered Thread

[devn]

James seems to work, but I am getting a macruby 0.10 GC error. I installed using rvm version 1.9.2.

Here's the script I'm running via james time_dialog.rb

James.dialog do

  hear 'What time is it?' => :time

  state :time do
    hear ['What time is it?', 'And now?'] => :time
    into { time = Time.now; "It is currently #{time.hour} #{time.min}." }
    exit {} # Optional, listed for completeness.
  end

  hear 'Play nickle back' => :nickelback
  state :nickelback do
    hear ['Play nickelback', 'Play nickle back'] => :nickelback
    into { "Sir, your musical taste is lacking. Might I suggest Rick Astley instead?" }
  end

end

`~> james time_dialog.rb
James: Using dialogs in time_dialog.rb for our conversation, Sir.
Possibilities:

1. James?
2. Are you there, James?
3. Good night, James.
   Possibilities:
4. Play Nickelback
5. Thank you, James.
6. Go back.
7. I need some time alone, James.
8. Good night, James.

Note that James continues to /run/, I just keep seeing this error and am wondering what's going on.

Hi Devin!

Thanks for the well described issue.

I am afraid that I can't tell you much more than that I've filed a ticket with MacRuby: https://www.macruby.org/trac/ticket/1421

You'll find more information regarding this there. (Including a link back to this) In short: It is benign, but of course nothing nice to look at.

Cheers,
Florian

Hey Florian,

Thanks for filing an issue on my behalf. I had the sneaking suspicion this issue would be closed out of hand as a problem with MacRuby and not with james. Feel free to close this issue or leave it open if you think it will be beneficial for other users to see it front-and-center on james' issues page.

Regards,
Devin

Hey Devin,

I'll leave it open for now – the point you mention is a good one.

Cheers,
Florian

I'm seeing a similar issue, with a little more information that could be helpful. James seems to work fine aside from the warning.

Hi @daveshenk! Thanks a lot for reporting. It seems, MacRuby closed this as "wontfix" as the problem seems to be in an OSX framework, see https://www.macruby.org/trac/ticket/1375.
