[ruby-list:21252] [BUG] unsaved context

もりきゅうです。

osv.rb:16: [BUG] unsaved context

実行してからしばらく待つと落ちます。

-- osv.rb
require 'socket'

require 'hello'

class ObjectServer
  def initialize
    @thread = nil
    @socket = nil
  end
  def start(port)
    begin
      @socket = TCPserver.open(port)
      print "server opened\n"
      while true
        @thread = Thread.start do
          receive_object(@socket.accept)
        end
      end
    rescue
      print "server failed: #$!\n"
    ensure
      @socket.close
    end
  end
  def receive_object(socket)
    begin
      object = Marshal.load(socket)
      method = Marshal.load(socket)
#      p [object, method]
      object.send(method)
      socket.close
      print "object is received.\n"
    rescue
      print "receive_object failed: #$!\n"
    end
  end
end

begin
  port = (ARGV.shift || '10000').to_i
  osv = ObjectServer.new
  osv.start(port)
rescue
  print "Illegal Argument: #$!\n"
  exit(1)
end

ループ内を以下のように変更すれば大丈夫みたいです。
--
      while true
        ns = @socket.accept
        @thread = Thread.start do
          s = ns
          receive_object(s)
#         receive_object(@socket.accept)
        end
      end
