2024-03-11 r/7678 feat(tvix/glue): Implement builtins.fetchurlAspen Smith11-54/+454
Implement the fetchurl builtin, and lay the groundwork for implementing the fetchTarball builtin (which works very similarly, and is implemented using almost the same code in C++ nix). An overview of how this works: 1. First, we check if the store path that *would* result from the download already exists in the store - if it does, we just return that 2. If we need to download the URL, TvixStoreIO has an `http_client: reqwest::Client` field now which we use to make the request 3. As we're downloading the blob, we hash the data incrementally into a SHA256 hasher 4. We compare the hash against the expected hash (if any) and bail out if it doesn't match 5. Finally, we put the blob in the store and return the store path Since the logic is very similar, this commit also implements a *chunk* of `fetchTarball` (though the actual implementation will likely include a refactor to some of the code reuse here). The main thing that's missing here is caching of downloaded blobs when fetchurl is called without a hash - I've opened b/381 to track the TODO there. Adding the `SSL_CERT_FILE` here is necessary to teach reqwest how to load it during tests - see 1c16dee20 (feat(tvix/store): use reqwests' rustls-native-roots feature, 2024-03-03) for more info.

This makes reqwest honor `SSL_CERT_FILE` - previously it was using the chain bundled in webpki-roots. `object_store` pulls in `reqwest` with this feature, and the cargo solver will enable that feature globally as soon as we pull it in, as it assumes features are additive. This requires setting `SSL_CERT_FILE` when running tests, otherwise they'll fail with the unhelpful "NotFound" error. This was quite some fun to debug, why adding `object_store` to tvix-castore suddenly made tvix-store tests fail!

2024-03-03 r/7633 fix(tvix/nix-compat): Make CAHash deserialize more formatsBrian Olsen3-67/+230
Currently CAHash only deserializes the hash in hex code while the serializer outputs a nixbase32 hash. This means that you can't currently deserialize what has been serialized. This change makes deserialize support any digest format (so hex, nixbase32 and base64) as well as flattens the deserialize code and error handling. It also implements serde methods of HashAlgo directly using Display and TryFrom implementations because otherwise these would get serialized as eg. Sha256 instead of sha256 which also broke CAHash serialize/deserialize.

2024-02-21 r/7591 feat(tvix/eval): Store string context alongside dataAspen Smith9-79/+377
Previously, Nix strings were represented as a Box (within Value) pointing to a tuple of an optional context, and another Box pointing to the actual string allocation itself. This is pretty inefficient, both in terms of memory usage (we use 48 whole bytes for a None context!) and in terms of the extra indirection required to get at the actual data. It was necessary, however, because with native Rust DSTs if we had something like `struct NixString(Option<NixContext>, BStr)` we could only pass around *fat* pointers to that value (with the length in the pointer) and that'd make Value need to be bigger (which is a waste of both memory and cache space, since that memory would be unused for all other Values). Instead, this commit implements *manual* allocation of a packed string representation, with the length *in the allocation* as a field past the context. This requires a big old pile of unsafe Rust, but the payoff is clear: hello outpath time: [882.18 ms 897.16 ms 911.23 ms] change: [-15.143% -13.819% -12.500%] (p = 0.00 < 0.05) Performance has improved. Fortunately this change can be localized entirely within value/string.rs, since we were abstracting things out nicely.

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.

2024-02-20 r/7575 feat(tvix/serde): add an example using nixpkgs/libVincent Ambo1-0/+34
This displays how users can configure an impure evaluation for tvix-serde, which makes it possible to use e.g. `nixpkgs/lib`. We might want to add an example showing how the full Nix-glue compatibility stuff can be added here, too.

2024-02-20 r/7574 fix(tvix/eval): make path resolution work by default in impure modeVincent Ambo1-0/+6
The previous behaviour (enabling `import`, but not allowing e.g. `<nixpkgs/lib>` to resolve) was very confusing. Now imports from NIX_PATH become enabled by default, unless the user already overrode that behaviour with something else by setting `Evaluation::nix_path` manually.

2024-02-20 r/7572 refactor(tvix/eval): use internal SourceCode field in error printersVincent Ambo4-27/+21
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.

2024-02-20 r/7571 refactor(tvix/eval): add SourceCode directly into error typesVincent Ambo6-40/+67
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.

Some implementations of DirectoryService might not allow retrieval of intermediate Directory nodes, that are not at the "root". Think about an object store implementation. 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.
