Establishing new TCP Socket connection

ruby-talk
1

Hi,

If I want to establish a new TCP connection every time I need to
access data (the server doesn't want to keep old connetions around),
is there any reason why I can't do something like:

def send_message_and_recv_response
  server = TCPSocket.new @server_ip, @server_port
  server.puts "the message"
  result = server.recv
end

No response needed on this... it all seems to work ok.

You could be more friendly to the other end by adding an explicit close:

def do_the_stuff
   sock = TCPSocket.new @ip, @port
   sock.puts "message"
   return sock.recv
ensure
   sock.close unless sock.nil?
end

Sure, except you should explicitly close the connection as well at the end of your block rather than letting the socket object's finalizer do it whenever the GC gets around to calling it. So, something like:

def send_message_and_recv_response
   server = nil
   server = TCPSocket.new @server_ip, @server_port
   server.puts "the message"
   result = server.recv
ensure
   server.close if server
end
