Async calling you must be running inside an eventmachine loop

[akshayrawat]

I'm using unicorn with trigger_async, and also have em-http-request in the Gemfile.

Running Rails, with pusher-gem (master), on Heroku.

I get:

Pusher::Error (In order to use async calling you must be running inside an eventmachine loop):

Yes, that's the way it works I'm afraid. Unicorn isn't built on top of eventmachine, thus you don't have the loop running.

It would be nice to support async triggering in rails that just works, but I haven't been able to devote any time to this as yet. For now, starting an eventmachine loop in a thread should work (Thread.new { EM.run }), but you should verify how this plays with the unicorn forking model.
