2022-09-17	r/4886 test(tvix/eval): Add the start of a nix oracle test suite	Griffin Smith	1	-30/+93
	Add the start of a test suite that compares tvix eval results against nix, using the string repr of the value as the comparison. This shells out to a nix-instantiate binary, which is configurable as an environment variable, to eval - there's some extra machinery there to setup a new nix store as a tempdir to allow running this test inside the nix build for tvix-eval itself. Currently this has a macro that'll allow writing lots and lots of hardcoded tests, but going forward I'm also going to be looking into adding proptest-based generation of expressions to compare.

2022-09-13	r/4827 chore(tvix/eval): add dependency on codemap-diagnostic	Vincent Ambo	1	-0/+21
	This is a crate for source-span based error reporting. Since all of our spans are already codemap spans, it is a good starting point. We have to figure out quite a bit of logic for neat error printing; later on if we want fancier presentation we might want to look at one of the other libraries in this space like miette.

2022-09-07	r/4707 chore(tvix/eval): add codemap dependency	Vincent Ambo	1	-0/+7
	This will be used to track source spans when emitting bytecode. The codemap is a data structure which tracks all the source files visited by an evaluation, and makes it possible to represent locations across all of the files using a simple span (i.e. pair of offsets). When reporting errors, this even contains enough information to reconstruct the rnix AST to create fancier reporting in certain cases if desired.

2022-09-01	r/4569 chore(tvix/eval): bump rnix-parser to latest master	Vincent Ambo	1	-1/+1
	In this commit, the string interpolation parsing is identical to nixpkgs which makes some of the upstream Nix tests for interpolation-related weirdness pass.

2022-09-01	r/4567 refactor(tvix/eval): Upgrade to latest rnix-parser	Vincent Ambo	1	-26/+15
	Since the latest published version of rnix-parser on crates.io, the crate has undergone major changes which are only available in the git repository at the moment. This commit updates the compiler to this newer version of rnix. Most notably, the entire AST provided by rnix is now wrapped in the AST type system. As a result of this traversal is much nicer in many places, especially for things like nested attribute selection. There are a handful of smaller features missing for full feature parity with the previous version, especially handling of path literals, but PRs for these already exist in rnix-parser.

2022-08-30	r/4533 feat(tvix/eval): implement optional runtime tracing	Vincent Ambo	1	-0/+10
	This adds a `disassembler` feature to the crate configuration that traces the operations executed and the state of the stack at runtime. This can be enabled by compiling with `--feature disassembler`. This will also gain a more sensible layout of code slices eventually.

2022-08-28	r/4520 fix(tvix/eval): use path_clean instead of fs::canonicalize for paths	Vincent Ambo	1	-0/+7
	Canonicalisation performs much more functionality than what C++ Nix implements for paths, and causes some undesirable behaviour (e.g. handling non-existant files becomes difficult, but should be possible in literals). Instead, the path_clean crate provides a pure normalisation method. There is an intention to add this to Rust itself: https://github.com/rust-lang/rfcs/issues/2208 Change-Id: I775d238136db0a52cf6b12a68985833c8fb32882 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6186 Tested-by: BuildkiteCI Reviewed-by: sterni <sternenseemann@systemli.org>

2022-08-26	r/4498 refactor(tvix/value): replace static representation with SmolStr	Vincent Ambo	1	-0/+1
	The only uses of the static variant were for `"name"` and `"value"`, which are both small enough to fit into a SmolStr. The size of NixString accomodates `String` anyways, so we may as well inline them. Additionally smol_str is already in the dependency graph because rnix uses it, and using it for representations of identifiers is sensible.
