Bug #2758: NoMethodError instead of Errno::ECONNREFUSED when Net::HTTP cannot connect
http://redmine.ruby-lang.org/issues/show/2758

Author: Mitch Williams
Status: Open, Priority: Normal
ruby -v: ruby 1.8.7 (2009-12-24 patchlevel 248) [i686-darwin10.2.0], MBARI 0x6770, Ruby Enterprise Edition 2010.01

The code:

require net/http.rb
n = Net::HTTP.new('server-that-is-not-listening-on-port-eighty')
n.request_head('/')

Used to throw: "Errno::ECONNREFUSED: Connection refused - connect(2)"

But after http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=25851 the code throws: "NoMethodError: undefined method `closed?' for nil:NilClass"

From line 1060 of net/http.rb.  It looks like the code was intended to close sockets in the event of an error, but it assumes the socket actually exists.
