backport_base_dir() click to toggle source

This backports base_dir which replaces installation path Rubygems 1.8+

# File lib/bundler/rubygems_integration.rb, line 279
def backport_base_dir
  Gem::Specification.send(:define_method, :base_dir) do
    return Gem.dir unless loaded_from

    @cache_file ||= File.join cache_dir, "#{full_name}.gem"
  end
end
backport_segment_generation() click to toggle source

This backports the correct segment generation code from Rubygems 1.4+ by monkeypatching it into the method in Rubygems 1.3.6 and 1.3.7.

# File lib/bundler/rubygems_integration.rb, line 260
def backport_segment_generation
  Gem::Version.send(:define_method, :segments) do

    @spec_file ||= File.join spec_dir, "#{full_name}.gemspec"
  end
end
backport_yaml_initialize() click to toggle source

This backport fixes the marshaling of @segments.

replace_bin_path(specs) click to toggle source

Used to make bin stubs that are not created by bundler work under bundler. The new Gem.bin_path only considers gems in specs

  gem_class.send(:remove_method, :bin_path)

    if exec_name == 'bundle'
      return ENV['BUNDLE_BIN_PATH']
    end

    spec = nil

    if exec_name
      spec = specs.find { |s| s.executables.include?(exec_name) }
      spec or raise Gem::Exception, "can't find executable #{exec_name}"

end
replace_entrypoints(specs) click to toggle source

Replace or hook into Rubygems to provide a bundlerized view of the world.

      return
    end

replace_refresh() click to toggle source

Because Bundler has a static view of what specs are available, we don't refresh, so stub it out.
