Cache dependency tree #114

Open russellpierce opened 7 years ago

russellpierce commented 7 years ago

Just walking the dependency tree for a lockfile can take a while. This makes starting up with lockbox a tad slow. It seems like one could digest the lockfile and store a cache of the dependency tree for subsequent start-ups to allow things to go a bit faster.

Agreed, this should be specifiable by an option. In our use case, we update dependencies of dependencies frequently and typically the full walk is preferred on every startup, but I understand this is atypical for most environments.

For a given .yml the dependency tree may change:

  1. If autoinstall: true
  2. When package A depends on B and A is in the yml but B is not and B is updated between runs?

... Are there some other cases that immediately occur to you?
