2024-02-20 r/7578 feat(tvix/eval): implement `builtins.filterSource`Ryan Lahfa9-69/+521
We add a new set of builtins called `import_builtins`, which will contain import-related builtins, such as `builtins.path` and `builtins.filterSource`. Both can import paths into the store, with various knobs to alter the result, e.g. filtering, renaming, expected hashes. We introduce `filtered_ingest` which will drive the filtered ingestion via the Nix function via the generator machinery, and then we register the root node to the path info service inside the store. `builtins.filterSource` is very simple, `builtins.path` is a more complicated model requiring the same logic albeit more sophisticated with name customization, file ingestion method and expected SHA-256.

2024-02-20 r/7577 fix(tvix/eval): propagate catchable errors at the top of an evalVincent Ambo3-6/+46
(Re-)Adds an error variant that wraps a catchable error kind, which is used for returning the result of an evaluation. Previously this would return the internal catchable value, which would lead to panics if users tried to use these. Somehow this was missed; I think we need error output tests.

Makes use of the SourceCode field now being stored directly in errors (see parent CL). With this change, the default `Display` implementation can now format errors correctly, and there is no need to keep a `SourceCode` around just for error formatting. Updates dependent crates (CLI, serde, tvixbolt) to use this correctly.

With this change it's no longer necessary to track the SourceCode struct separately from the evaluation for error reporting: It's just stored directly in the errors. This also ends up resolving an issue in compiler::bindings, where we cloned the Arc containing file references way too often. In fact those clones probably compensate for all additional SourceCode clones during error construction now.

The client is doing a get_recursive anyways to reduce the number of roundtrips. By documenting the fact we don't need to support looking up intermediate Directory messages, we can just batch all directories into the same object, keyed by the root.

2024-02-18 r/7551 feat(tvix/glue): drive builds on IOFlorian Klink5-13/+192
That's one possible abstraction to drive builds. Whenever IO into a store path is requested, we look up the root node, and in case we don't have it in PathInfoService, but KnownPaths gives us a Derivation for that output path, trigger a build and await the result. This recursively might trigger builds for parent paths if they haven't been built yet. Another option would be to simply expose a PathInfoService interface for a builder too, and loop all building into IO via PathInfoService composition - but let's start with something. Note tvix-cli doesn't have a configurable BuildService yet, it's plugged to the DummyBuildService, so whenever it needs to do a build, it'll fail, but that's how it can be provoked: ``` (builtins.readFile (import <nixpkgs> {}).hello.outPath + "/bin/hello") […] error[E029]: I/O error: /nix/store/cg8a576pz2yfc1wbhxm1zy4x7lrk8pix-hello-2.12.1: builds are not supported with DummyBuildService --> [code]:1:2 | 1 | (builtins.readFile (import <nixpkgs> {}).hello.outPath + "/bin/hello") | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ``` Note how this fails, while pure output path calculation (`(import <nixpkgs> {}).hello.outPath + "/bin/hello")`) still succeeds.

2024-02-17 r/7531 feat(nix-compat/derivation): simplify derivation_or_fod_hashFlorian Klink1-29/+22
Populate the input_derivations struct field in-place, using self.input_derivations.from_iter, which seems a bit more readable.

This is was dropped accidentially, but we actually want to run tests in debug mode, to check for overflows.

2024-02-13 r/7509 test(tvix/eval): Add test asserting size of ValueAspen Smith1-0/+8
Now that I've done a ton of things to make sure Value is small on the stack (16 bytes, which is a perfectly reasonable size for a programming language Value enum), add a test asserting it stays that way. These size improvements have a measurable impact, too - here's the `hello outpath` benchmark compared between canon (as of r/7495) and this commit: hello outpath time: [990.56 ms 995.83 ms 1.0070 s] change: [-7.1397% -6.1302% -5.1651%] (p = 0.00 < 0.05) Performance has improved.

2024-02-13 r/7508 feat(tvix/eval): Box Value::CatchableAspen Smith11-40/+45
This is now the only enum variant for Value that is larger than 8 bytes (it's 16 bytes), so boxing it (especially since it's not perf-critical) allows us to get the Value size down to only 16 bytes!

2024-02-13 r/7507 revert(tvix/eval): Don't double-box Path valuesAspen Smith6-23/+20
This reverts commit d3d41552cf1f6485f8ebc597a2128a0d15b030a5. This was well-intentioned, but now the boxed Path values are actually the *largest* Value enum variants, at 16 bytes (because they're fat-pointers, with a len) instead of 8 bytes like all the other values. Having the double reference is a reasonable price to pay (it seems; more benchmarks may end up disagreeing) for a smaller Value repr.

2024-02-13 r/7506 fix(tvix/eval): Replace inner NixString repr with Box<Bstr>Aspen Smith5-65/+92
Storing a full BString here incurs the extra overhead of the capacity for the inner byte-vector, which we basically never use as Nix strings are immutable (and we don't do any mutation / sharing analysis). Switching to a Box<BStr> cuts us from 72 bytes to 64 bytes per string (and there are a lot of strings!)

2024-02-10 r/7497 refactor(tvix/eval): Box the strings in CatchableErrorKindAspen Smith3-13/+14
These strings are allocated once and never changed, so they don't need the additional overhead of a capacity given by String - instead, we can use Box<str> and save on 16 bytes for each of these, *and* for each Value since this is currently the largest Value variant.
