Class Method Details

.start(app, given_options = nil) ⇒ Object

Pass given app to the Handler, handler is chosen based on config.adapter option. If there is a method named start_name_of_adapter it will be run instead of the default run method of the handler, this makes it easy to define custom startup of handlers for your server of choice.

def self.start(app, given_options = nil)
  options.merge!(given_options) if given_options

  handler = options[:handler].to_s.downcase
  config = { :Host => options[:host], :Port => options[:port] }

  Log.debug "Using #{handler}"

  if respond_to?(method = "start_#{handler}")
    send(method, app, config)
  else
    Rackup::Handler.get(handler).run(app, config)
  end
end

.start_ebb(app, config) ⇒ Object

Due to buggy autoload on Ruby 1.8 we have to require ‘ebb’ manually. This most likely happens because autoload doesn’t respect the require of rubygems and uses the C require directly.

def self.start_ebb(app, config)
  require 'ebb'
  # Rack doesn't ship with ebb handler, but it doesn't get picked up under some
  # circumstances, so we do that here.
  # Jruby Rack doesn't have the Handler::register method, so we have to check.
  # This has changed since Rack moved Handler to Rackup.  Not sure about JRuby
  if Rackup::Handler.respond_to?(:register)
    Rackup::Handler.register('ebb', 'Rackup::Handler::Ebb')
  end
  Rackup::Handler.get('ebb').run(app, config)
end

.start_thin(app, config) ⇒ Object

Thin shouldn’t give excessive output, especially not to $stdout
