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.

Constant Summary

GemHelpers - Included

GENERICS, GENERIC_CACHE

Class Method Summary

Instance Attribute Summary

FetchMetadata - Included

#matches_current_ruby?

A fallback is included because the original version of the specification API didn’t include that field, so some marshalled specs in the index have it set to nil.
#matches_current_rubygems?

MatchMetadata - Included

#matches_current_ruby?, #matches_current_rubygems?

Instance Method Summary

MatchPlatform - Included

#match_platform

GemHelpers - Included

#generic, #generic_local_platform, #local_platform, #platform_specificity_match, #same_deps, #same_specificity, #select_best_platform_match, #sort_best_platform_match

Dynamic Method Handling

  

    This class handles dynamic methods through the method_missing method

# File 'lib/bundler/remote_specification.rb', line 108



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 43



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 54



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 102



def _remote_specification
  @_remote_specification ||= @spec_fetcher.fetch_spec([@name, @version, @original_platform])
  @_remote_specification || raise(GemspecError, "Gemspec data for #{full_name} was" \
    " missing from the server!")
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

# File 'lib/bundler/remote_specification.rb', line 28



def fetch_platform
  @platform = _remote_specification.platform

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
    

    
  
    •
