The code of `lib.closePropagation` was internally using a recursion on the dependencies and returns all the derivation directly or indirectly referenced by buildInputs. `lib.closeProgation` is implemented in pure nix and uses an unique function for list which is quadratic and does "true" equality, which needs deep set comparison. Instead, we use the `builtins.genericClosure` which is implemented as a builtin and uses a more efficient sorting feature. Note that `genericClosure` needs a `key` to discriminate the values, we used the `outPath` which is unique and orderable. On benchmarks, it performs up to 15x time faster on a benchmark related to haskellPackages.ghcWithPackages. |
