2023-09-04 r/6550 refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crateFlorian Klink1-0/+12
This trait is eval-specific, there's no point in dealing with these things in tvix-store. This implements the EvalIO interface for a Tvix store. The proper place for this glue code (for now) is tvix-cli, which knows about both tvix-store and tvix-eval. There's one annoyance with this move: The `tvix-store import` subcommand previously also used the TvixStoreIO implementation (because it conveniently did what we wanted). Some of this code had to be duplicated, mostly logic to calculate the NAR-based output path and create the PathInfo object. Some, but potentially more of this can be extracted into helper functions in a shared crate, and then be used from both TvixStoreIO in tvix-cli as well as the tvix-store CLI entrypoint.

2023-08-20 r/6512 refactor(tvix/nix-compat/nixhash): validate digest lengthsFlorian Klink5-38/+87
There was a NixHash::new() before, which didn't perform any validation of the digest length. We had some length validation when parsing nix hashes or SRI hashes, but some places didn't perform validation and/or constructed the struct directly. Replace NixHash::new() with a `impl TryFrom<(HashAlgo, Vec<u8>)> for NixHash`, which does do this validation, and update constructing code to use that, rather than populating structs directly. In some rare cases where we're sure the digest length is correct we still populate the struct manually. Fixes b/291.

2023-08-20 r/6494 feat(tvix/nix-compat): don't swallow hash validation errorsRyan Lahfa3-58/+208
Previously, Output deserialization would silence validation errors and provide `None` for `hash_with_mode` as soon as a validation error would happen inside of the `NixHashWithMode` deserialization, e.g. invalid hash length would not provide an validation error but a silent `None` value. This is problematic, we workaround a serde limitation here by writing our own Deserializer. As you can see, we write some boilerplate code unfortunately, as, for example: - `#[serde(fail_if_unparsed_as="Option::is_none")]` is not a thing, otherwise, we could have been able to just bubble up errors in case of "not fully parsed" (and not missing) values. - `From<&serde_json::Value> for serde::de::Unexpected` is not a thing, otherwise, we could just map invalid type errors and reuse the existing types instead of doing extremely bizarre things with `serde::de::Unexpected::Other`, note: this is a not problem for expected, we know what we expect, we don't know what we received in practice. I decided to write a `NixHashWithMode::from_map` which will eat a map deserialized via `serde_json`, so our serde magic is not totally "data model" agnostic. I wanted to go for data model agnosticity and enable maximal performance, e.g. building the structure as the map values are streamed in the Visitor, this is needlessly painful because `Output` and `NixHashWithMode` are in different files and this really makes sense only if we write the full implementation in one file, indeed, otherwise, you end up duplicating the work or having strange coupling. So, for now, we will allocate a full map of the fields inside the `Output`, i.e. if any "unknown field" is in that map, we will deserialize it for no reason. Doing it properly, as I repeat it in the code and to flokli at C3Camp 2023, requires to patch serde upstream IMHO.

Some paths might use names that are not valid UTF-8. We should be able to represent them.

This being a nested error makes things more complicated than necessary. Also, this caused BuildStorePathError to only hold NameError, so refactor these utility functions to either return Error, or BuildStorePathError.

2023-05-10 r/6129 feat(tvix/nix-compat/nar/writer): check for more data in readerFlorian Klink1-1/+14
We already returned UnexpectedEof in case the reader stopped returning bytes too early, but similarly we should also fail if there's still bytes left to be read in the reader passed. We normally use the NAR writer to produce new NAR files, so the readers point to the blobs we actually want to render, and having some data left in there should be an error. If for some reason the reader points to more data than just the blob, the `.take` method can be used to limit it to the (known) size.

2023-04-09 r/6088 refactor(nix-compat): Properly encapsulate store path constructionJohn Ericson7-112/+257
Before there was code scattered about (e.g. text hashing module and derivation output computation) constructing store paths from low level building blocks --- there was some duplication and it was easy to make nonsense store paths. Now, we have roughly the same "safe-ish" ways of constructing them as C++ Nix, and only those are exposed: - Make text hashed content-addressed store paths - Make other content-addressed store paths - Make input-addressed fixed output hashes Change-Id: I122a3ee0802b4f45ae386306b95b698991be89c8 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8411 Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI
