Ruby

Is there any way to catch Timeout::ERROR exception throw by timeout
() ?

====[cut here]======
#!/usr/bin/env ruby

require ‘open-uri’
require ‘timeout’

begin
open(“http://6.6.6.6/”){}
rescue => e
puts e.message
puts “I’m still running”
end
====[and here]====

output
/sw/lib/ruby/1.8/timeout.rb:42:in new': execution expired (Timeout::Error) from /sw/lib/ruby/1.8/net/protocol.rb:83:in connect’

Timeout::Error

rescue => e
rescue Timeout::Error => e

    puts e.message
    puts "I'm still running"

end

Beware!

You should use a subclass of Timeout::Error when nesting timeouts
(Net::HTTP has timeouts inside) so that you don’t trap the wrong
timeout in the wrong place and run forever:

irb(main):002:0> open(‘http://localhost:8080/’)
/usr/local/lib/ruby/1.8/timeout.rb:43:in `rbuf_fill’: execution
expired (Timeout::Error)
