Module: Hudkins::HostLookup

Defined in:
lib/hudkins/restclient.rb

Overview

the idea behind this is that if the hudson server isn’t available, getaddrinfo has a really long timeout.. like over 20 seconds! This is really a DNS issue, but I still don’t want to wait that long and I couldn’t figure out how to set a better timeout.
