[jruby-dev] [jira] (JRUBY-7122) File.realpath does not handle classpath:/ path on Windows

Sat, 09 Mar 2013 09:28:03 -0800

Issue Type: Bug Bug
Affects Versions: JRuby 1.7.3
Assignee: Unassigned
Components: Core Classes/Modules
Created: 09/Mar/13 11:27 AM
Description:

I am running JRuby inside OSGi bundle which starts JRuby scripting container from jruby-complete-1.7.3.jar. In this case jar is not extracted in filesystem, all files are required from class path. As a result $LOAD_PATH is set to

["classpath:/META-INF/jruby.home/lib/ruby/1.9/site_ruby",
 "classpath:/META-INF/jruby.home/lib/ruby/shared",
 "classpath:/META-INF/jruby.home/lib/ruby/1.9"]



On Linux and Mac OS X everything is working fine but on Windows




require "openssl"




is raising exception




org.jruby.rack.RackInitializationException: No such file or directory - classpath:C:/META-INF/jruby.home/lib/ruby/shared/krypt.rb
	from org/jruby/RubyFile.java:760:in `realpath'






It is happening because on Windows File.realpath is not handling path which starts with "classpath:/..." (pointing to file that should be required from class path and not from file system). And File.realpath is used by require_relative which is used by krypt.rb.



The problem can be demonstrated with the following test which is working without problems on Linux or Mac OS X:




$ java -cp jruby-complete-1.7.3.jar org.jruby.Main -S jirb
>> File.realpath("classpath:/META-INF/jruby.home/lib/ruby/shared/krypt.rb")
=> "classpath:/META-INF/jruby.home/lib/ruby/shared/krypt.rb"
>> require "classpath:/META-INF/jruby.home/lib/ruby/shared/krypt.rb"
=> true






But on Windows it is giving exception:




C:\>java -cp jruby-complete-1.7.3.jar org.jruby.Main -S jirb
irb(main):001:0> File.realpath("classpath:/META-INF/jruby.home/lib/ruby/shared/krypt.rb")

As you can see on Windows C:/ is inserted in classpath:/META-INF/... path.



As I understand the cause for this is in Windows specific code in RubyFile.java method expandPathInternal but I have not yet debugged to exact line in this method which is causing this.
