build(gemfile, lockfile, unlock) click to toggle source

Given a gemfile and lockfile creates a Bundler definition

@param gemfile [Pathname] Path to Gemfile @param lockfile [Pathname,nil] Path to Gemfile.lock @param unlock [Hash, Boolean, nil] Gems that have been requested

to be updated or true if all gems should be updated

How does the new system work?

  • Load information from Gemfile and Lockfile

  • Invalidate stale locked specs

  • All specs from stale source are stale

  • All specs that are reachable only through a stale dependency are stale.

  • If all fresh dependencies are satisfied by the locked

specs, then we can try to resolve locally.
