I've this ruby code that connects to a TCP server (namely, netcat). It loops 20 times, and sends "ABCD ". If I kill netcat, it takes TWO iterations of the loop for an exception to be triggered. On the first loop after netcat is killed, no exception is triggered, and "send" reports that 5 bytes have been correctly written... Which in the end is not true, since of course the server never received them.
Is there a way to work around this issue ? Right now I'm losing data : since I think it's been correctly transfered, I'm not replaying it.
#!/usr/bin/env ruby
require 'rubygems'
require 'socket'
sock = TCPSocket.new('192.168.0.10', 5443)
sock.sync = true
20.times do
sleep 2
begin
count = sock.write("ABCD ")
puts "Wrote #{count} bytes"
rescue Exception => myException
puts "Exception rescued : #{myException}"
end
end
