ruby - ruby 中的 TCPServer，代码卡住了

Question

我正在用 ruby​​ 构建一个小游戏来练习编程，到目前为止一切顺利，但我正在尝试实现多人游戏支持，我可以连接到服务器并且可以发送信息但是当我尝试从服务器读取时它只是卡住，我的屏幕完全变黑。我找不到原因，我阅读了用于 TCP 的 gem 的文档，但我不知道，也许我错过了一些东西，但如果你们中的任何人有一些见解，我将非常感激

如果这段代码还不够，这里是repo

这是客户端代码

class Client
  include Celluloid::IO
  def initialize(server, port)
    begin
      @socket = TCPSocket.new(server, port)
    rescue
      $error_message = "Cannot find game server."
    end
  end
  def send_message(message)
    @socket.write(message) if @socket
  end
  def read_message
    @socket.readpartial(4096) if @socket
  end
end

这是游戏服务器

require 'celluloid/autostart'
require 'celluloid/io'
class Server
  include Celluloid::IO
  finalizer :shutdown
  def initialize(host, port)
    puts "Starting Server on #{host}:#{port}."
    @server = TCPServer.new(host, port)
    @objects = Hash.new
    @players = Hash.new
    async.run
  end
  def shutdown
    @server.close if @server
  end
  def run
    loop { async.handle_connection @server.accept }
  end
  def handle_connection(socket)
    _, port, host = socket.peeraddr
    user = "#{host}:#{port}"
    puts "#{user} has joined the arena."
    loop do
      data = socket.readpartial(4096)
      data_array = data.split("\n")
      if data_array and !data_array.empty?
        begin
          data_array.each do |row|
            message = row.split("|")
            if message.size == 10
              case message[0] 
              when 'obj'
                @players[user] = message[1..9] unless @players[user]
                @objects[message[1]] = message[1..9]
              when 'del'
                @objects.delete message[1]
              end
            end
            response = String.new
            @objects.each_value do |obj|
              (response << obj.join("|") << "\n") if obj
            end
            socket.write response
          end
        rescue Exception => exception
          puts exception.backtrace
        end
      end # end data
    end # end loop
  rescue EOFError => err
    player = @players[user]
    puts "#{player[3]} has left"
    @objects.delete player[0]
    @players.delete user
    socket.close
  end
end
server, port = ARGV[0] || "0.0.0.0", ARGV[1] || 1234
supervisor = Server.supervise(server, port.to_i)
trap("INT") do
  supervisor.terminate
  exit
end
sleep

it just freezes and my screen goes completely black. and i cant find the cause

您可以看看的一个好技巧是使用 rbspy 附加到您的进程或 rbtrace看看它卡住时是怎么回事。

您也可以先尝试减少此处的依赖性，然后使用简单的线程池执行此操作，然后再与赛璐珞或事件机器完全异步。
