I've been trying to get basic async HTTP calls to work in my app.
I've tried using some code in my app from the Rails 3 async stack demo: http://github.com/igrigorik/async-rails, but I'm getting "can't yield from root fiber" and I have no idea where to go from here. Here's the top of my trace:
(eval):10:in `yield'
(eval):10:in `get'
app/controllers/home_controller.rb:62:in `index'
/Users/ct/.rvm/gems/ruby-1.9.2-rc2@og/gems/actionpack-3.0.0.beta4/lib/action_controller/metal/implicit_render.rb:4:in `send_action'
/Users/ct/.rvm/gems/ruby-1.9.2-rc2@og/gems/actionpack-3.0.0.beta4/lib/abstract_controller/base.rb:145:in `process_action'
my index controller method is simply:
def index
http = EM::HttpRequest.new("http://www.google.com/").get
render :text => http.response
end
I've got all the right gems, I've got 1.9.2-rc2, rails 3 beta 4, and I'm running thin. I also got the async-rails app itself to run fine using the same rvm and gemset. The eventmachine reactor is definitely running in my app. I'd love any hints about how to get this working properly!
