module Bundler
  # The CompactIndexClient is responsible for fetching and parsing the compact index.
  #
  # The compact index is a set of caching optimized files that are used to fetch gem information.
  # The files are:
  # - names: a list of all gem names
  # - versions: a list of all gem versions
  # - info/[gem]: a list of all versions of a gem
  #
  # The client is instantiated with:
  # - `directory`: the root directory where the cache files are stored.
  # - `fetcher`: (optional) an object that responds to #call(uri_path, headers) and returns an http response.
  # If the `fetcher` is not provided, the client will only read cached files from disk.
  #
  # The client is organized into:
  # - `Updater`: updates the cached files on disk using the fetcher.
  # - `Cache`: calls the updater, caches files, read and return them from disk
  # - `Parser`: parses the compact index file data
  # - `CacheFile`: a concurrency safe file reader/writer that verifies checksums
  #
  # The client is intended to optimize memory usage and performance.
  # It is called 100s or 1000s of times, parsing files with hundreds of thousands of lines.
  # It may be called concurrently without global interpreter lock in some Rubies.
  # As a result, some methods may look more complex than necessary to save memory or time.

    # because we use it to generate the etag on first request during the upgrade
    # to the compact index client that uses opaque etags saved to files.
    # Remove once 2.5.0 has been out for a while.
