ruby-xz breaks Resolv.getaddress in ruby 2.2.x about ruby-xz

[Quintus]

Weird. I just tested your script, and I can reproduce the problem. However, I don’t think it is related to io-like, because this works as intended:

#!/usr/bin/env ruby
require 'resolv'
require "io/like"
puts Resolv.getaddress('google.com')

$ ruby -v
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

This will require some debugging. Thanks for reporting!

Oh yes. Such a great bug. This was the cause:

class XZ::StreamReader < XZ::Stream
  # ...
  self.class.send(:alias_method, :open, :new)
  # ...
end

What this intended to do is to alias a class method. However, self is XZ::StreamReader in this context (the class object), so self.class is Class (the Ruby class for class objects). So what the code really did was redefining Class#open, which in turn seems to have quite nasty side effects.

However, it appears I accidentally fixed the problem already in commit a4ec945, where I removed that statement and replaced it with an explicit method definition, because I wanted to add a deprecation warning for a certain use of that alias. So, could you please test with current devel again? If you need a gem, you can run rake gem to build one.

After running bundle clean, I was able to verify this bug is fixed with the following Gemfile:

source 'https://rubygems.org'
ruby '2.2.0'
gem 'ruby-xz', :git => 'https://github.com/Quintus/ruby-xz.git', :ref => '48e1fe2f2898056275eba73725d6e0df0eefb0dd'

Thanks for the fix! Looking forward to the released gem :)

Okay, thanks for testing. It will be included into the next release 0.2.2 then.

Do you have an ETA for a 0.2.2 release?

[Quintus]

Thanks for reminding me. I just released 0.2.2 and pushed it to rubygems.org.

Happy coding!

Thanks!

Due to a documentation error, I also released 0.2.3. The source code of 0.2.2 and 0.2.3 is otherwise identical.
