2024-05-06 r/8080 feat(tvix/store): use async nar reader for ingest_narFlorian Klink1-3/+5
Rename read_nar to ingest_nar, and have it use the async nar reader version, and the ingest_entries machinery. This means we can now drop all code dealing with manually assembling castore nodes. Update our consumer, NixHTTPPathInfoService to use the new API. As we now accept an AsyncRead, we don't need to do any blocking here anymore, and can use the same async-compression crate as in the fetching logic (and support some more compression formats out of the box).

2024-04-23 r/7996 feat(tvix/glue/fetchers): support file:// URLsFlorian Klink1-0/+1
Nix supports file:// - URLs for `fetchurl` and `fetchTarball`. Convert the enums and function arguments to hold a URL type. reqwest::Url is a re-export of the url crate, but they don't re-export the parsing errors, and as we want to hold these in our Error types, add it to Cargo.toml explicitly. The Fetcher::download function now checks on the scheme, and either opens the file locally, or does do a HTTP request as before. Fetch gets its custom debug impl, removing potentially sensitive username and password out of URLs.

2024-04-23 r/7993 refactor(tvix/glue): move Fetch[er] into its own types, fetch lazilyFlorian Klink1-0/+2
We actually want to delay fetching until we actually need the file. A simple evaluation asking for `.outPath` or `.drvPath` should work even in a pure offline environment. Before this CL, the fetching logic was quite distributed between tvix_store_io, and builtins/fetchers.rs. Rather than having various functions and conversions between structs, describe a Fetch as an enum type, with the fields describing the fetch. Define a store_path() function on top of `Fetch` which can be used to ask for the calculated store path (if the digest has been provided upfront). Have a `Fetcher` struct, and give it a `fetch_and_persist` function, taking a `Fetch` as well as a desired name, and have it deal with all the logic of persisting the PathInfos. It also returns a StorePathRef, similar to the `.store_path()` method on a `Fetch` struct. In a followup CL, we can extend KnownPaths to track fetches AND derivations, and then use `Fetcher` when we need to do IO into that store path.

Implement a first pass at the fetchTarball builtin. This uses much of the same machinery as fetchUrl, but has the extra complexity that tarballs have to be extracted and imported as store paths (into the directory- and blob-services) before hashing. That's reasonably involved due to the structure of those two services.

2024-04-15 r/7928 fix(tvix/castore/directory): fix graph traversalFlorian Klink1-0/+1
Use a proper graph library to ensure all nodes are reachable from the root. We had a bit of that handrolled during add(), as well as later, which had an annoying bug: Redundant nodes were omitted during insert, but when returning the list during finalize, we did not properly account they need to be introduced before their parents are sent. We now simply populate a petgraph DiGraph during insert (skipping inserting nodes we already saw), and use petgraph's DfsPostOrder to traverse the graph during finalize. If the number of returned indices equals the total number of nodes in the graph, all nodes are reachable from the root, we can consume the graph and return the nodes as a vec, in the same order as the traversal (and insertion). Providing a regression test for the initial bug is challenging, as the current code uses a bunch of HashSets. I manually tested ingesting a full NixOS closure using this mechanism (via gRPC, which exposes this problem, as it validates twice), and it now works.

This allows copying individual store paths from the local /nix/store into tvix-store. As we don't support getting this information from Nix yet, we currently expect metadata to be provided externally: Nix' `exportReferencesGraph` feature contains pretty much all data we need for this. Expect a list of this information at a well-known key (`closure`, similar to nixpkgs' `pkgs/build-support/binary-cache/ default.nix`). We currently simply upload all store paths sequentially, without any parallelism or awareness in how the reference graph looks like. As long as the connected stores don't enforce this, this is fine, at least for now.

This brings some initial Nix wire format parsing code, used in the nix daemon protocol, remote store/builder protocol, as well as the NAR format itself (note we already have more specialized code for the last one). Thanks to embr, this code already exists, in https://codeberg.org/gorgon/gorgon/src/branch/main/nix-daemon/src/wire.rs, and we can vendor it into here, as EUPL is compatible with GPL (in that direction). The code uses the tokio::io Reader and Writer traits, not the ones from the `futures` crate, as they provide some more convenient `read_u64_le` functions. More application-specific parsing code, as well as code to read strings, or bytes are left out for now, as we want to be be more restrictive w.r.t allowed max sizes, and need to parse bytes, not strings. The code slightly diverges, as we have clippy looped into CI. `Ok(…?)` can be turned into just the inner expression, and some .and_then can be expressed in a simpler fashion.

2024-03-11 r/7678 feat(tvix/glue): Implement builtins.fetchurlAspen Smith1-0/+2
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.

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.

2024-02-18 r/7551 feat(tvix/glue): drive builds on IOFlorian Klink1-0/+2
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.

2024-01-31 r/7460 fix(tvix): Represent strings as byte arraysAspen Smith1-0/+12
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.

This is an additional test suite on the top of the Nix ones for context strings matters. It already smoked out multiple mistakes and potential bugs and non-deterministic result from the evaluator. It uses a similar technology as the one in the tvix-eval albeit we instantiate a fully fledged evaluator with in-memory store. We copy the files instead of symlinking them because crates are built in isolation, so symlinks cannot work.

2024-01-17 r/7403 fix(tvix/eval): `getContext` merges underlying valuesRyan Lahfa1-533/+445
Previously, we were assembling very naively an attribute set composed of context we saw. But it was forgetting that `"${drv}${drv.drvPath}"` would contain 2 contexts with the same key, but with different values, one with `outputs = [ "out" ];` and `allOutputs = true;`. Following this reasoning and comparing with what Nix does, we ought to merge underlying values systematically. Hence, I bring `itertools` to perform a group by on the key and merge everything on the fly, it's not beautiful but it's the best I could find, notice that I don't use `group_by` but I talk about group by, that is, because `group_by` is a `group_by_consecutive`, see https://github.com/rust-itertools/itertools/issues/374. Initially, I tried to do it without a `into_grouping_map_by`, it was akin to assemble the final `NixAttrs` directly, it was less readable and harder to pull out because we don't have a lot of in-place mutable functions on our data structures.

2024-01-12 r/7376 feat(tvix/glue/derivationStrict): support __structuredAttrsFlorian Klink1-10/+13
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.
