Sorry, I couldn't find a Trak site or anything.
Working on deploying a project to Engine Yard using Webistrano (1.0
and 1.1). Deploys were "failing" in sudo_behavior_callback
(invocation.rb) on receiving an empty prompt from the server, in the
"else fallback.call..." portion of the method.
Since I couldn't figure out where "fallback" was supposed to be set,
and I couldn't imagine how anything useful could be done with an empty
prompt anyway, I patch the line
fallback.call(ch, stream, out)
to read
fallback.call(ch, stream, out) unless out.nil? || out.strip.empty?
I thought this might be helpful to someone else.
