listen() click to toggle source

Sets up signals and starts the DRb service. If it’s successful, it doesn’t return. Not ever. You don’t need to override this.

    # File lib/spork/server.rb, line 24
24:   def listen
25:     raise RuntimeError, "you must call Spork.using_spork! before starting the server" unless Spork.using_spork?
26:     trap("SIGINT") { sig_int_received }
27:     trap("SIGTERM") { abort; exit!(0) }
28:     trap("USR2") { abort; restart } if Signal.list.has_key?("USR2")
29:     @drb_service = DRb.start_service("druby://127.0.0.1:#{port}", self)
30:     Spork.each_run { @drb_service.stop_service } if @run_strategy.class == Spork::RunStrategy::Forking
31:     stderr.puts "Spork is ready and listening on #{port}!"
32:     stderr.flush
33:     DRb.thread.join
34:   end

run(argv, stderr, stdout) click to toggle source

This is the public facing method that is served up by DRb. To use it from the client side (in a testing framework):

  DRb.start_service("druby://localhost:0") # this allows Ruby to do some magical stuff so you can pass an output stream over DRb.
                                           # see http://redmine.ruby-lang.org/issues/show/496 to see why localhost:0 is used.
  spec_server = DRbObject.new_with_uri("druby://127.0.0.1:8989")
  spec_server.run(options.argv, $stderr, $stdout)

When implementing a test server, don’t override this method: override run_tests instead.

    # File lib/spork/server.rb, line 46
46:   def run(argv, stderr, stdout)
47:     run_strategy.run(argv, stderr, stdout)
48:   end
