Establishing new TCP Socket connection
 

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 =3D TCPSocket.new @server_ip, @server_port
server.puts "the message"
result =3D 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
