-------------------------------------
Summary: JRuby 1.9 mode require does multiple requires and extra
file system searching
Key: JRUBY-6610
URL: https://jira.codehaus.org/browse/JRUBY-6610
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.6.7
Reporter: Thomas E Enebo
Priority: Blocker
Fix For: JRuby 1.7
Our 1.9 logic seems to be searching through filesystem to try and determine the
canonical path we are storing our loads under in features. It appears MRI is
not doing this. This little program (make an 'a' and 'b' directory both
containing a 'test.rb' with different contents) demonstrates us double loading
where MRI will not (tried against MRI 1.9.2 and 1.9.3):
{noformat}
$LOAD_PATH << 'a'
require 'test'
$LOAD_PATH[0] = 'b'
require 'test'
{noformat}
Our resolution process may be a significant load cost for things like rails
which has a lot of the same requires sprinkled around their codebase.
