eventmachine

I am running a Sinatra app within an EventMachine.run loop and in my ws.onopen method I wish to check the handshake header's cookie to ensure that the incoming request is coming from a registered user of my webapp. My Sinatra app includes the following: use Rack::Session::Cookie, :key => COOKIE_KEY, :path => '/', :expire_after => 2592000, #30 days :secret => COOKIE_SECRET and my ws.onopen method looks like this (trimmed) ws.onopen { |handshake| cookie, bakesale = handshake.headers['Cookie'].split('=') rack_cookie = Rack::Session::Cookie.new(MyApp, { :key => COOKIE_KEY, :path => '/', :expire

Update: the eventmachine gem is installed and in my gemfile: eventmachine (1.0.0, 0.12.10) Please help! Trying to create a database with the following: Fitzs-MacBook-Pro:twilio_insanity Fitz$ rake db:create' Returns the following error: Unable to load the EventMachine C extension; To use the pure-ruby reactor, require 'em/pure_ruby' rake aborted! cannot load such file -- rubyeventmachine /Users/Fitz/.rvm/gems/ruby-1.9.3-p327@rails3tutorial2ndEd/gems/eventmachine-1.0.0/lib/eventmachine.rb:8:in require' /Users/Fitz/.rvm/gems/ruby-1.9.3-p327@rails3tutorial2ndEd/gems/eventmachine-1.0.0/lib

In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitely is). Open the file for reading and read a chunk on each tick (but how much to read? too much and it'll block the reactor, too little and reading will get slower than necessary). EM.popen('cat some/file', FileReader) feels really weird, but works better than the

I have been using Sinatra for sometime now and I would like to add some realtime features to my web-app by pushing the data via websockets. I have successfully used the gem 'em-websocket' on its own, but have not been able to write one ruby file that has a sinatra web server AND a web-socket server. I've tried spinning the run! or start! methods off in separate threads with no success. Has anyone gotten this to work? I want to have them in the same file as I can then share variables between the two servers. Thanks! Konstantin Haase Did not try it, but should not be too hard: require 'em

From the wikipedia Reactor Pattern article: The reactor design pattern is an event handling pattern for handling service requests delivered concurrently to a service handler by one or more inputs. It named a few examples, e.g. nodejs , twisted , eventmachine But what I understand that above is popular event driven framework, so make them also a reactor pattern framework? How to differentiate between these two? Or they are the same? The reactor pattern is more specific than "event driven programming". It is a specific implementation technique used when doing event driven programming. However,

When I run an app on Lion OS X, I get this error: Unable to load the EventMachine C extension; To use the pure-ruby reactor, require 'em/pure_ruby' /Users/adam/.rvm/gems/ruby-1.9.2-p290/gems/eventmachine-1.0.0/lib/eventmachine.rb:8:in `require': no such file to load -- rubyeventmachine (LoadError) from /Users/adam/.rvm/gems/ruby-1.9.2-p290/gems/eventmachine-1.0.0/lib/eventmachine.rb:8:in `<top (required)>' from /Users/adam/.rvm/gems/ruby-1.9.2-p290@global/gems/bundler-1.0.21/lib/bundler/runtime.rb:68:in `require' from /Users/adam/.rvm/gems/ruby-1.9.2-p290@global/gems/bundler-1.0.21/lib/bundler
