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 File.dirname File.dirname loaded_from end end

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 @segments ||= @version.scan(%r[0-9]+|[a-z]+/).map do |s| %r^\d+$/ =~ s ? s.to_i : s end end end

Used to make bin stubs that are not created by bundler work under bundler.
The new Gem.bin_path only considers gems in specs
# File lib/bundler/rubygems_integration.rb, line 209 def replace_bin_path(specs) gem_class = (class << Gem ; self ; end) gem_class.send(:remove_method, :bin_path) gem_class.send(:define_method, :bin_path) do |name, *args| exec_name = args.first 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}" else spec = specs.find { |s| s.name == name } exec_name = spec.default_executable or raise Gem::Exception, "no default executable for #{spec.full_name}" end gem_bin = File.join(spec.full_gem_path, spec.bindir, exec_name) gem_from_path_bin = File.join(File.dirname(spec.loaded_from), spec.bindir, exec_name) File.exist?(gem_bin) ? gem_bin : gem_from_path_bin end end
Replace or hook into Rubygems to provide a bundlerized view of the world.

# File lib/bundler/rubygems_integration.rb, line 123 def replace_gem(specs) executables = specs.map { |s| s.executables }.flatten ::Kernel.send(:define_method, :gem) do |dep, *reqs| if executables.include? File.basename(caller.first.split(':').first) return end reqs.pop if reqs.last.is_a?(Hash) unless dep.respond_to?(:name) && dep.respond_to?(:requirement) dep = Gem::Dependency.new(dep, reqs) end spec = specs.find { |s| s.name == dep.name } if spec.nil? e = Gem::LoadError.new "#{dep.name} is not part of the bundle. Add it to Gemfile." e.name = dep.name if e.respond_to?(:requirement=) e.requirement = dep.requirement else e.version_requirement = dep.requirement end raise e elsif dep !~ spec e = Gem::LoadError.new "can't activate #{dep}, already activated #{spec.full_name}. " "Make sure all dependencies are added to Gemfile." e.name = dep.name if e.respond_to?(:requirement=) e.requirement = dep.requirement else e.version_requirement = dep.requirement end raise e end true end end
Because Bundler has a static view of what specs are available, we don’t refresh, so stub it out.
