2023-01-23 r/5740 refactor(tvix/derivation): relax bounds for reference iteratorVincent Ambo1-2/+2
This makes it easier to pass owned strings if that's what we have. Change-Id: Ia7351ff2681292d16534ec50fe60b926b683bb9a Reviewed-on: https://cl.tvl.fyi/c/depot/+/7908 Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI
2023-01-23 r/5737 feat(tvix/derivation): add `path_with_references`Vincent Ambo1-0/+36
This allows the calculation of a store path for a plain string that potentially contains references. These paths are used for `builtins.toFile` (and potentially other features of C++ Nix).

2023-01-18 r/5700 feat(tvix/derivation): add validate_output_paths flag for validateFlorian Klink1-1/+1
This allows calling validate() on a derivation that doesn't have its output paths already calculated yet. It allows offloading some of the error checking in builtins.derivation* to be offloaded to that function.

2023-01-13 r/5657 refactor(tvix/derivation): use BTreeSet for derivation outputsVincent Ambo1-3/+5
When constructing derivations inside builtins.derivationStrict, we'd have to very frequently check whether certain outputs have already been inserted into the derivation inputs. Using a set type is much easier, especially as this has to be ordered and the source data that is being inserted also comes from a set, which might let us pass this more efficiently in the future. Note that the validate function no longer checks the order of the entries, as that is now guaranteed by the type.

2023-01-07 r/5623 feat(tvix/derivation): derive Default for DerivationFlorian Klink1-31/+20
Some of the fields in a Derivation struct stay empty, and manually creating BTreeMap or vec for it is annoying. Derive Default instead, so we can use the defaults instead of writing more by hand.

2023-01-06 r/5616 fix(tvix/derivation): fix build after StorePath renameVincent Ambo1-4/+3
This project was not previously covered by CI (fixed in this commit), so we didn't catch breakage due to a renamed module. This was noticed while rebasing a CL that has a dependency on this crate in its Nix build.

As discussed in #tvl, this is a more common term for it. Change-Id: I9b904222b8c076f82192c9b7f0b42be171614ab7 Reviewed-on: https://cl.tvl.fyi/c/depot/+/7776 Reviewed-by: tazjin <tazjin@tvl.su> Tested-by: BuildkiteCI
2023-01-06 r/5612 test(tvix/derivation): add output_path_construction testFlorian Klink1-1/+156
This exercises the output path calculation functions like a constructing client (an implementation of builtins.derivation) would do. It first assembles the bar derivation, does the output path calculation on it, then continues with the foo derivation. The code ensures the resulting Derivations match our fixtures.

This moves all the hash compression logic into a common helper function. Also update the docstring, which said "path" here, which could have been confused with output paths.

Use the #[serde(rename = "…")] field attributes to match the field names that Nix uses in its JSON output (nix show-derivation). This allows us to just re-use the exact same fixtures from go-nix, without manual post-massaging.
