- we do the following:
-
- - For all paths still to be processed (‘todo’), we add all
- paths for which we need info to the set ‘query’. For an
- unbuilt derivation this is the output paths; otherwise, it's
- the path itself.
-
- - We get info about all paths in ‘query’ in parallel.
-
- - We process the results and add new items to ‘todo’ if
- necessary. E.g. if a path is substitutable, then we need to
- get info on its references.
-
- - Repeat until ‘todo’ is empty.
