Overview

Represents a lazily loaded gem specification, where the full specification is on the source server in rubygems’ “quick” index. The proxy object is to be seeded with what we’re given from the source’s abbreviated index - the full specification will only be fetched when necessary.

Dynamic Method Handling

  

    This class handles dynamic methods through the method_missing method

# File 'lib/bundler/remote_specification.rb', line 106



def method_missing(method, *args, &blk)
  _remote_specification.send(method, *args, &blk)
end

Instance Method Details



  

    #<=>(other)  
  



  

    

Compare this specification against another object. Using sort_obj is compatible with ::Gem::Specification and other ::Bundler or RubyGems objects. Otherwise, use the default Object comparison.


  



  [ GitHub ]


  

  


# File 'lib/bundler/remote_specification.rb', line 41



def <=>(other)
  if other.respond_to?(:sort_obj)
    sort_obj <=> other.sort_obj
  else
    super
  end
end


  








  

    #__swap__(spec)  
  



  

    

Because Rubyforge cannot be trusted to provide valid specifications once the remote gem is downloaded, the backend specification will be swapped out.


  





  
Raises:





  [ GitHub ]


  

  


# File 'lib/bundler/remote_specification.rb', line 52



def __swap__(spec)
  raise APIResponseInvalidDependenciesError unless spec.dependencies.all? {|d| d.is_a?(Gem::Dependency) }

  SharedHelpers.ensure_same_dependencies(self, dependencies, spec.dependencies)
  @_remote_specification = spec
end


  








  

    #_remote_specification   (private)

# File 'lib/bundler/remote_specification.rb', line 100



def _remote_specification
  @_remote_specification ||= @spec_fetcher.fetch_spec([@name, @version, @platform])
  @_remote_specification || raise(GemspecError, "Gemspec data for #{full_name} was" \
    " missing from the server! Try installing with `--full-index` as a workaround.")
end


  








  

    #fetch_platform  
  



  

    

Needed before installs, since the arch matters then and quick specs don’t bother to include the arch in the platform string


  



  [ GitHub ]


  

  


# File 'lib/bundler/remote_specification.rb', line 26



def fetch_platform
  @platform = _remote_specification.platform
end

  if platform == Gem::Platform::RUBY || platform.nil?

# File 'lib/bundler/remote_specification.rb', line 110



def respond_to?(method, include_all = false)
  super || _remote_specification.respond_to?(method, include_all)
end


  








  

    #sort_obj  ⇒ Array 
  



  

    

Create a delegate used for sorting. This strategy is copied from RubyGems 2.23 and ensures that Bundler’s specifications can be compared and sorted with RubyGems’ own specifications.


  





  
Returns:


    
  
  • 
    (Array)
—    
    

    an object you can use to compare and sort this specification against other specifications
    

    
  
    •
