Overview

The Base dispatcher simply makes it easier to write dispatchers by inheriting from it. It creates a Waves request, ensures the request processing is done within a mutex, benchmarks the request processing, logs it, and handles common exceptions and redirects. Derived classes need only process the request within their safe method, which takes a Waves::Request and returns a Waves::Response.

def call( env )
  Waves::Application.instance.synchronize do
    request = Waves::Request.new( env )
    response = request.response
    t = Benchmark.realtime do
      begin
        safe( request )
      rescue Dispatchers::Redirect => redirect
        response.status = redirect.status
        response.location = redirect.path
      end
    end
    Waves::Logger.info "#{request.method}: #{request.url} handled in #{(t*1000).round} ms."
    response.finish
  end
end

#deferred?(env) ⇒ Boolean

Called by event driven servers like thin and ebb. Return true if the server should run the request in a separate thread.

Returns:

  • (Boolean)
