2024-08-20 r/8545 refactor(nix-compat/store_path): make StorePath generic on SFlorian Klink2-11/+11
Similar to how cl/12253 already did this for `Signature`, we apply the same logic to `StorePath`. `StorePathRef<'a>'` is now a `StorePath<&'a str>`, and there's less redundant code for the two different implementation. `.as_ref()` returns a `StorePathRef<'_>`, `.to_owned()` gives a `StorePath<String>` (for now). I briefly thought about only publicly exporting `StorePath<String>` as `StorePath`, but the diff is not too large and this will make it easier to gradually introduce more flexibility in which store paths to accept. Also, remove some silliness in `StorePath::from_absolute_path_full`, which now doesn't allocate anymore.

Add a `SymlinkTarget` type to represent validated symlink targets.

2024-08-17 r/8504 refactor(tvix/castore): remove `name` from NodesFlorian Klink2-15/+6
Nodes only have names if they're contained inside a Directory, or if they're a root node and have something else possibly giving them a name externally. This removes all `name` fields in the three different Nodes, and instead maintains it inside a BTreeMap inside the Directory. It also removes the NamedNode trait (they don't have a get_name()), as well as Node::rename(self, name), and all [Partial]Ord implementations for Node (as they don't have names to use for sorting). The `nodes()`, `directories()`, `files()` iterators inside a `Directory` now return a tuple of Name and Node, as does the RootNodesProvider. The different {Directory,File,Symlink}Node struct constructors got simpler, and the {Directory,File}Node ones became infallible - as there's no more possibility to represent invalid state. The proto structs stayed the same - there's now from_name_and_node and into_name_and_node to convert back and forth between the two `Node` structs. Some further cleanups: The error types for Node validation were renamed. Everything related to names is now in the DirectoryError (not yet happy about the naming) There's some leftover cleanups to do: - There should be a from_(sorted_)iter and into_iter in Directory, so we can construct and deconstruct in one go. That should also enable us to implement conversions from and to the proto representation that moves, rather than clones. - The BuildRequest and PathInfo structs are still proto-based, so we still do a bunch of conversions back and forth there (and have some ugly expect there). There's not much point for error handling here, this will be moved to stricter types in a followup CL.

2024-08-13 r/8486 refactor(tvix/castore): move *Node and Directory to crate rootFlorian Klink2-3/+2
*Node and Directory are types of the tvix-castore model, not the tvix DirectoryService model. A DirectoryService only happens to send Directories. Move types into individual files in a nodes/ subdirectory, as it's gotten too cluttered in a single file, and (re-)export all types from the crate root. This has the effect that we now cannot poke at private fields directly from other files inside `crate::directoryservice` (as it's not all in the same file anymore), but that's a good thing, it now forces us to go through the proper accessors. For the same reasons, we currently also need to introduce the `rename` functions on each *Node directly. A followup is gonna move the names out of the individual enum kinds, so we can better represent "unnamed nodes".

2024-08-13 r/8484 refactor(tvix/castore): use Directory struct separate from proto oneYureka2-22/+19
This uses our own data type to deal with Directories in the castore model. It makes some undesired states unrepresentable, removing the need for conversions and checking in various places: - In the protobuf, blake3 digests could have a wrong length, as proto doesn't know fixed-size fields. We now use `B3Digest`, which makes cloning cheaper, and removes the need to do size-checking everywhere. - In the protobuf, we had three different lists for `files`, `symlinks` and `directories`. This was mostly a protobuf size optimization, but made interacting with them a bit awkward. This has now been replaced with a list of enums, and convenience iterators to get various nodes, and add new ones.

The "path" key in the arguments to builtins.path supports any path-coercible type (a string, a path...). Coerce it to a path in the argument rather than just requiring it already be one and throwing an error if it's not.

Make constructing of a new Evaluation use the builder pattern rather than setting public mutable fields. This is currently a pure refactor (no functionality has changed) but has a few advantages: - We've encapsulated the internals of the fields in Evaluation, meaning we can change them without too much breakage of clients - We have type safety that prevents us from ever changing the fields of an Evaluation after it's built (which matters more in a world where we reuse Evaluations). More importantly, this paves the road for doing different things with the construction of an Evaluation - notably, sharing certain things like the GlobalsMap across subsequent evaluations in eg the REPL.

This shouldn't be part of the PathInfoService trait.

Move it out into its own NarCalculationService trait, defined somewhere at tvix_store::nar, and have everyone who wants to trigger nar calculation use nar_calculation_service directly, which now is an additional field in TvixStoreIO for example. It being moved outside the PathInfoService trait doesn't prohibit specific implementations to implement it (like the GRPC client for the `PathInfoService` does.

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.

(Our only) one of these seekable source implementations is now doing exactly that. We produce a stream of futures, and then use [StreamExt::buffered] to process more than one, concurrently.

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. This is (unfortunately) not easy to test in an automated way, but I've tested it manually for now and it seems to work: tvix-repl> (import ../. {}).third_party.nixpkgs.hello.outPath => "/nix/store/dbghhbq1x39yxgkv3vkgfwbxrmw9nfzi-hello-2.12.1" :: string Co-authored-by: Connor Brewster <cbrewster@hey.com> Change-Id: I57afc6b91bad617a608a35bb357861e782a864c8 Reviewed-on: https://cl.tvl.fyi/c/depot/+/11020 Autosubmit: aspen <root@gws.fyi> Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI
2024-04-19 r/7979 refactor(tvix/castore): generalize store ingestion streamsConnor Brewster1-23/+5
Previously the store ingestion code was coupled to `walkdir::DirEntry`s produced by the `walkdir` crate which made it impossible to reuse ingesting from other sources like tarballs or NARs. This introduces a `IngestionEntry` which carries enough information for store ingestion and a future for computing the Blake3 digest of files. This allows the producer to perform file uploads in a way that makes sense for the source, ie. the filesystem upload could concurrently upload multiple files at the same time, while the NAR ingestor will need to ingest the entire blob before yielding the next blob in the stream. In the future we can buffer small blobs and upload them concurrently, but the full blob still needs to be read from the NAR before advancing.

2024-04-13 r/7899 feat(tvix/eval): contextful JSON operationsRyan Lahfa1-4/+3
`toJSON` transform a Nix structure into a JSON string. For each context in that Nix structure, the JSON string must possess it. Thus, it is necessary to take the union of all contexts and attach it to the final structure. Unfortunately, the return type of `into_json` is a serde's JSON object, not a string. Therefore, it is not possible to reuse `NixString` machinery. Context tests are reinforced as Nix does not test those behaviors. Fixes b/393.

2024-04-09 r/7882 fix(tvix): Avoid buffering file into memory in builtins.hashFileConnor Brewster1-3/+3
Right now `builtins.hashFile` always reads the entire file into memory before hashing, which is not ideal for large files. This replaces `read_to_string` with `open_file` which allows calculating the hash of the file without buffering it entirely into memory. Other callers can continue to buffer into memory if they choose, but they still use the `open_file` VM request and then call `read_to_string` or `read_to_end` on the `std::io::Reader`.

2024-03-11 r/7678 feat(tvix/glue): Implement builtins.fetchurlAspen Smith5-45/+322
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.

2024-02-21 r/7591 feat(tvix/eval): Store string context alongside dataAspen Smith2-16/+12
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.
