2024-01-31 r/7460 fix(tvix): Represent strings as byte arraysAspen Smith1-31/+41
C++ nix uses C-style zero-terminated char pointers to represent strings internally - however, up to this point, tvix has used Rust `String` and `str` for string values. Since those are required to be valid utf-8, we haven't been able to properly represent all the string values that Nix supports. To fix that, this change converts the internal representation of the NixString struct from `Box<str>` to `BString`, from the `bstr` crate - this is a wrapper around a `Vec<u8>` with extra functions for treating that byte vector as a "morally string-like" value, which is basically exactly what we need. Since this changes a pretty fundamental assumption about a pretty core type, there are a *lot* of changes in a lot of places to make this work, but I've tried to keep the general philosophy and intent of most of the code in most places intact. Most notably, there's nothing that's been done to make the derivation stuff in //tvix/glue work with non-utf8 strings everywhere, instead opting to just convert to String/str when passing things into that - there *might* be something to be done there, but I don't know what the rules should be and I don't want to figure them out in this change. To deal with OS-native paths in a way that also works in WASM for tvixbolt, this also adds a dependency on the "os_str_bytes" crate.

2024-01-18 r/7410 feat(tvix/glue): use TvixStoreIO as derivation builtin stateRyan Lahfa1-5/+4
We propagate a `TvixStoreIO` as the `state` of our derivation-specific builtins in the glue crate. The evaluators `io_handle` itself is using a Rc<dyn EvalIO>. An earlier version of TvixStoreIO was also introducing generics over the different internal services themselves, but we opted for instead hardcoding this to Arc<dyn …> for the sake of less macro voodoo.

Rather than passing strings around, use a StorePathRef. This makes things a bit more typesafe, and more aligned with what we want to do in b/264.

2024-01-12 r/7376 feat(tvix/glue/derivationStrict): support __structuredAttrsFlorian Klink1-169/+190
This adds support to handle the __structuredAttrs argument, which can be passed to builtins.derivationStrict. If __structuredAttrs is passed, and set to true, most of the arguments passed to builtins.derivationStrict are not simply coerced to a string and passed down to "environments", but instead kept in a more structured fashion. Inside ATerm, which is what's relevant as far as path calculation is concerned, a virtual `__json` environment variable is present, containing these structured values. Inside Builds, these structured values are not made available as an environment variable, but a JSON file (and source-able bash script). This will need to be respected once we start emitting BuildRequests, and for that we can probably just parse the `__json` key in Derivation.environment again - or keep this additionally in non-serialized form around during Evaluation. No matter what, this is left for a followup CL. The existing handle_derivation_parameters and populate_outputs helper function were removed, as __structuredAttrs causes quite a change in behaviour, and so handling both in the same place makes it more readable. There's some open questions w.r.t. string contexts for structured attrs itself. A TODO is left for this, but at least path calculation for individual structured attrs derivations are correct now. Part of b/366. Change-Id: Ic293822266ced6f8c4826d8ef0d2e098a4adccaa Reviewed-on: https://cl.tvl.fyi/c/depot/+/10604 Tested-by: BuildkiteCI Reviewed-by: raitobezarius <tvl@lahfa.xyz>
2024-01-03 r/7338 feat(tvix/glue): contextful derivationRyan Lahfa1-64/+63
We calculate the input context by performing the union of context over all input of the derivation. Then, we just pass the rest of it to the remaining machinery. Finally, we re-emit an `outPath` and a `drvPath` containing the expected contexts.

2023-12-14 r/7218 fix(tvix/eval): remove incorrect imports when coercingsterni1-5/+14
The default behavior of string coercion in C++ Nix is to weakly coerce and import to store if necessary. There is a flag to make it strongly coerce (coerceMore) and a flag that controls whether path values have the corresponding file/directory imported into the store before returning the (store) path as a string (copyToStore). We need to implement our equivalent to the copyToStore (import_paths) flag for the benefit of weak coercions that don't import into the store (dirOf, baseNameOf, readFile, ...) and strong coercions that don't import into the store (toString). This makes coerce_to_string as well as CoercionKind weirder and more versatile, but prevents us from reimplementing parts of the coercion logic constantly as can be seen in the case of baseNameOf. Note that it is not possible to test this properly in //tvix/eval tests due to the lack of an appropriate EvalIO implementation being available. Tests should be added to //tvix/glue down the line.

This commit adjusts the error produced by STRUCTURED_ATTRS so that it is catchable. This way we are able to enumerate the release packageset, and the enumeration process will simply treat the few derivations using structured attributes as being broken, rather than killing the whole eval session.
