Still TODO:

  • Deprecating more of the "constituents" feature which we can't support with nix-eval-jobs (and isn't used on h.n.o anyway).
  • Finding a way to forbid IFD per-eval (h-e-j has a flag, n-e-j doesn't)

Future improvements: actually streaming the n-e-j results instead of parsing the whole output at once at the end!

For consistency with other Lix forks of Nix ecosystems projects, e.g.
nix-eval-jobs.

The feature cannot easily be ported to nix-eval-jobs since it requires
deep integration into the evaluator, and h.n.o doesn't use it. Later
more of this will be ripped out.

nix-eval-jobs streams output, unlike hydra-eval-jobs. Now that we've
migrated, we can use this to:

1. Use less RAM by avoiding buffering a whole eval's worth of metadata
   into a Perl string and an array of JSON objects.
2. Make evals latency a bit lower by allowing the queue runner to start
   ingesting builds faster.
