Private Instance Methods

download_cache_path(spec) click to toggle source

Returns the global cache path of the calling Rubygems::Source object.

Note that the Source determines the path’s subdirectory. We use this subdirectory in the global cache path so that gems with the same name – and possibly different versions – from different sources are saved to their respective subdirectories and do not override one another.

@param [Gem::Specification] specification

@return [Pathname] The global cache path.

download_gem(spec, download_cache_path, previous_spec = nil) click to toggle source

Checks if the requested spec exists in the global cache. If it does, we copy it to the download path, and if it does not, we download it.

@param [Specification] spec

the spec we want to download or retrieve from the cache.

@param [String] download_cache_path

the local directory the .gem will end up in.

@param [Specification] previous_spec

the spec previously locked
