2024-06-13 r/8263 fix(tvix/glue/tvix_store_io): disable concurrent fetches for nowFlorian Klink1-1/+3

We immediately reported "Building", even though then populated necessary inputs, which looked a bit odd. Make it clear we're still waiting, and update the spinner message once we have all inputs we were waiting for. In the future, we might want to have separate spans for this, so the timer gets reset, but that's something for later.

2024-06-12 r/8254 feat(tvix/glue): support builtin:fetchurlFlorian Klink5-15/+197
nixpkgs calls <nix/fetchurl.nix> during nixpkgs bootstrap. This produces a fake derivation with system = builtin and builder = builtin:fetchurl, and needs to download files from the internet. At the end of the Derivation construction, if we have such a derivation, also synthesize a `Fetch` struct, which we add to the known fetch paths. This will then cause these fetches to be picked up like all other fetches in TvixStoreIO.

This adds the necessary enum type and path calculation logic for it to the fetcher code. It also adds code to do the actual NAR fetching. The executable case is still stubbed out.

This shouldn't be part of the PathInfoService trait. Pretty much none of the PathInfoServices do implement it, and requiring them to implement it means they also cannot make use of this calculation already being done by other PathInfoServices. 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. This is currently wired together in a bit of a hacky fashion - as of now, everything uses the naive implementation that traverses blob and directoryservice, rather than composing it properly. I want to leave that up to a later CL, dealing with other parts of store composition too.

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.

Rather than carrying around an Future in the IngestionEntry::Regular, simply carry the plain B3Digest. Code reading through a non-seekable data stream has no choice but to read and upload blobs immediately, and code seeking through something seekable (like a filesystem) probably knows better what concurrency to pick when ingesting, rather than the consuming side. (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. We still keep the same order, to avoid shuffling things and violating the stream order. This also cleans up walk_path_for_ingestion in castore/import, as well as ingest_dir_entries in glue/tvix_store_io.

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. 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 Brewster2-34/+17
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 Lahfa5-6/+38
`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 Brewster3-33/+29
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`.

The most important part of this builtin is to perform all the relevant invariant validations to avoid letting the user craft invalid contexts which can never be built, e.g. invalid store paths, inexistent derivations, etc. This version is incomplete and full of TODOs, but passes all the Nix's context strings tests, so we turn them on.
