conflict between HighLine and Mechanize

[bleything]

I'm not really sure what's happening here:

#!/usr/bin/env ruby -w

require 'rubygems'
require 'mechanize'
require 'highline'
require 'highline/import'

WWW::Mechanize.new.get "http://gooogle.com"
ask "wha?"

yields:

wha?
/Library/Ruby/Gems/1.8/gems/highline-1.5.1/lib/highline.rb:603:in `get_line': The input stream is exhausted. (EOFError)
    from /Library/Ruby/Gems/1.8/gems/highline-1.5.1/lib/highline.rb:624:in `get_response'
    from /Library/Ruby/Gems/1.8/gems/highline-1.5.1/lib/highline.rb:218:in `ask'
    from /tmp/foo.rb:7

I'm at a loss here :(

This is a known issue caused by some oddities in Ruby's threading model (Mechanize uses threads). We did a bunch of experiments when we first spotted it and the behavior can change depending on whether or not Ruby was compiled with pthread support and whether or not any thread had been started before HighLine was first invoked. It's pretty odd stuff and I have reported it to the core team.

We did add an option to help with this though. You can shut off HighLine's EOF tracking with:

HighLine.track_eof = false

That should eliminate the error for you.

Oh wow. That's brutal. I googled around a bit but didn't find anything.

I'm glad to hear that option is present, I'll check it out. Thanks, James!
