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.

Constructor Details

.new(name, version, platform, spec_fetcher) ⇒ RemoteSpecification

[ GitHub ]

  
# File 'lib/bundler/remote_specification.rb', line 16

def initialize(name, version, platform, spec_fetcher)
  @name         = name
  @version      = Gem::Version.create version

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &blk) (private)

[ GitHub ]

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

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

def dependencies
  @dependencies ||= begin
    deps = method_missing(:dependencies)

    # allow us to handle when the specs dependencies are an array of array of string
    # in order to delay the crash to `#__swap__` where it results in a friendlier error
    # see https://github.com/rubygems/bundler/issues/5797
    deps = deps.map {|d| d.is_a?(Gem::Dependency) ? d : Gem::Dependency.new(*d) }

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.

[ 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)

[ GitHub ]

  
# 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

#full_name

[ GitHub ]

  
# File 'lib/bundler/remote_specification.rb', line 30

def full_name
  if platform == Gem::Platform::RUBY || platform.nil?
    "#{@name}-#{@version}"
  else
    "#{@name}-#{@version}-#{platform}"
  end
end

#git_version

[ GitHub ]

  
# File 'lib/bundler/remote_specification.rb', line 89

def git_version
  return unless loaded_from && source.is_a?(Bundler::Source::Git)
  " #{source.revision[0..6]}"
end

#respond_to?(method, include_all = false) ⇒ Boolean

[ GitHub ]

  
# 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_objArray

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
