class Bundler::RemoteSpecification

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.

Public Instance Methods

<=>(other) click to toggle source

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.

Calls superclass method Object#<=>
# 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) click to toggle source

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

# File lib/bundler/remote_specification.rb, line 54
def __swap__(spec)
  SharedHelpers.ensure_same_dependencies(self, dependencies, spec.dependencies)
  @_remote_specification = spec
end

# File lib/bundler/remote_specification.rb, line 99
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

    # allow us to handle when the specs dependencies are an array of array of string
    # see https://github.com/bundler/bundler/issues/5797
    deps = deps.map {|d| d.is_a?(Gem::Dependency) ? d : Gem::Dependency.new(*d) }

    deps
  end
end
fetch_platform() click to toggle source

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

def fetch_platform
  @platform = _remote_specification.platform
end

sort_obj() click to toggle source

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.

@see #<=> @see Gem::Specification#sort_obj

@return [Array] an object you can use to compare and sort this

specification against other specifications
