Timeout::timeout and Socket timeout

ruby-talk
1

Hi ..

I would like to suggest that Socket trap ETIMEDOUT and raise Timeout::Error
when a socket timeout occurs. This would allow the following:

   begin
     Timeout::timeout(to) do
         t = TCPSocket.new(host,port)

···

#
               # do socket stuff
               #
         t.close
      end
   rescue Timeout::Error => e
      p "Timeout --> #{e}"
   rescue Exception => e
        p "Exception --> #{e}"
   end

Rather than having a separate rescue clause.

Any thoughts?

Hi ..

when a socket timeout occurs.

I would oppose that.

These are two different error conditions: one is a socket error from the
kernel (the stack has failed to open a TCP connection), and the other is a
user-defined timeout. I'd certainly want to be able to distinguish them.

This would allow the following:

   begin
     Timeout::timeout(to) do
         t = TCPSocket.new(host,port)
               #
               # do socket stuff
               #
         t.close
      end
   rescue Timeout::Error => e
      p "Timeout --> #{e}"
   rescue Exception => e
        p "Exception --> #{e}"
   end

Rather than having a separate rescue clause.

Any thoughts?

Assyming you want both types of exception to hit the "Timeout --> #{e}"
line, then all you need to do is

   rescue Timeout::Error, Errno::ETIMEDOUT => e
      p "Timeout --> #{e}"

Brian.
