Open-uri timeout

ruby-talk

I love open-uri, but does anyone know how to configure the time-out
before open() will throw a Timeout::Error? I'd like to make it
shorter.

I'm trying to download some documents from a server that sometimes
works fine, but other times seems to ignore HTTP requests entirely. If
a download doesn't begin after a few seconds, I want to give up on the
request and try again. Ideas are welcome.

the simple way is

   require 'timeout'

   retries = 42

   begin
     Timeout::timeout(s){
       open('http://a.url.com') do |f|
         # ... stuff with f
       end
     }
   rescue Timeout::Error
     retries -= 1
     if retry > 0
       sleep 0.42 and retry
     else
       raise
     end
   end

Thanks, that's great. It seems to be working.
