Establishing new TCP Socket connection

Joe Van Dyk

7/5/2005 9:03:00 PM

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

Trying? What's stopping him? He's been in office for 21 months.
Closing it was a high priority when he was campaigning. But how often
do you hear him talking about it these days? He probably spends
more time on putting greens at lavish country clubs than he spends
trying to close Gitmo.

You passionately demanded that it be closed when Bush was in
office. But you have sold your soul to protect Obama and the rest
of the party.

: He needs Congressional approval to relocate the prisoners, little right
: wing American coward. Why won't the cowards of the American right give
: that permission to him?

The looney tune brain dead lying fascist hate spewing loser lib dems had a
filibuster proof majority in congress. They could have passed anything they wanted
to pass and there would have been nothing the Republicans could have done to stop
them.
