Timeout exceptions

ruby-talk

I'm trying to figure out how to handle and exception..

I have the following code:
def whois_info
  begin
    Timout::timeout(5) do
      File.read("urls.txt").each_line do |lookup| #file containing urls
        info = system("whois #{lookup}")
        File.open("whois_log.txt", "a+") {|whois| whois.puts(info)}
      end
    end
  rescue #what I want to do is rescue exception to have it skip the line and move onto the next one.

How do I do this..?
I've tried
rescue Timeout::Error
  next

But that just throws invalid next; compile error

Next can only be used inside of a loop/block. You're not because your begin/rescue is outside of all of them. Your layer logic is incorrect. Put the timeout at the right level and it'll work fine.

What would the correct level look like?

Well... what are you trying to time out? Put that inside and have everything else outside.

So something along the lines of:

File.read("urls.txt").each_line do |lookup|
  Timeout::timeout(5) do
     begin
       Whois lookup
       save to file
    rescue Timeout::Error
      next
    end
  end
end

Does that look about right?
