Ruby中的多線程

Question

我有一個用ruby制作的TCPserver，該服務器似乎正常工作，可以看到兩個或多個客戶端可以連接並由該服務器提供服務，但是有時它們會卡住（因為需要等待另一個客戶端斷開連接或只是變得不響應），通常在“ pass_ok”位之后，僅與一個客戶端連接時，我看不到此問題。

這是我的代碼：

  def self.main_server
    begin
      server = TCPServer.open(@port)
    rescue Exception => e
      CoreLogging.syslog_error("Cant start server: #{e}")
    end
    @main_pid = Process.pid
    # Main Loop
    Thread.abort_on_exception = true
    while true
      Thread.fork(server.accept) do |client|
        @client = client
        sock_domain, remote_port, remote_hostname, remote_ip = @client.peeraddr # Get some info on the incoming connection
        CoreLogging.syslog_error("Got new connection from #{@client.peeraddr[3]} Handeled by Thread: #{Thread.current}") # Log incoming connection 
        @client.puts "Please enter password: " # Password testing (later will be from a config file or DB)
        action = @client.gets(4096).chomp # get client password response 'chomp' is super important 
        if action == @password 
          # what to do when password is right
          pass_ok
          Thread.exit
        else 
          # what to do when password is wrong
          pass_fail
          Thread.exit
        end
      end

      begin
        CoreLogging.syslog_error("Thread Ended (SOFT)")
      rescue Exception => e
        CoreLogging.syslog_error("Thread was killed (HARD)")
      end
    end
  end

我將其留在此處以供將來參考，希望親近的人會發現它有用。

問題是全局@client變量，該變量將覆蓋每個新線程，然后繼承到該線程內的子類。

使用本地客戶端變量（不帶“ @”）可使它按預期工作。
