我创建谁接受所有的连接，并执行进来的数据具有命令行TCP服务器，但是当我发出“退出”到的TCPSocket，过程和插座不密妥
# main.cr
require "socket"
PORT = 2022
def handle_connection(socket)
Process.run("/bin/sh", input: socket, output: socket, error: socket)
end
server = TCPServer.new(PORT)
loop do
if socket = server.accept?
spawn handle_connection(socket)
else
break
end
end
例如，下面的代码工作精细，发送“退出”到STDIN后，外壳退出“过程结束”被printedand程序密切
channel = Channel(Nil).new
spawn do
Process.run("/bin/sh", input: STDIN, output: STDOUT, error: STDERR)
puts "process ending"
channel.send(nil)
end
channel.receive
对于debuggin目的，我已经测试此代码太多，但“结束进程”从来没有打印，直到我手动关闭TCP套接字
# main.cr
require "socket"
PORT = 2022
def handle_connection(socket)
Process.run("/bin/sh", input: socket, output: socket, error: socket)
puts "process ending"
end
server = TCPServer.new(PORT)
loop do
if socket = server.accept?
spawn handle_connection(socket)
else
break
end
end
当我运行main.cr， nc localhost 2022和发送“退出”我预计接近插槽正确，但他不，当我发送更多的指令中的程序产生错误
