2024-04-13 r/7890 feat(tvix/nix-compat): implement Serialize, Deserialize for NixHashFlorian Klink1-1/+1
We use the (slightly more tolerant) from_str to deserialize, and serialize out as SRI. Change-Id: If76b0ed2d4e243904f02df34f6c90b976c0bab8c Reviewed-on: https://cl.tvl.fyi/c/depot/+/11393 Tested-by: BuildkiteCI Reviewed-by: raitobezarius <tvl@lahfa.xyz>
2024-03-14 r/7694 refactor(nix-compat/derivation): emphasize aterm_bytesFlorian Klink1-12/+13
derivation_or_fod_hash constructs ATerm bytes and feeds them to sha256. input_derivations being slightly modified is an implementation detail, so move the BTreeMap construction inline, and have aterm_bytes in a let binding (and feed it to the hash function directly while constructing it). This makes it a bit more understandable what's going on.

2024-03-14 r/7691 refactor(nix-compat/store_path): take [u8;32] for outer fingerprintFlorian Klink3-22/+18
The outer fingerprint used for store path calculation is always a sha256 digest. This includes both input and output-addressed store paths. We used a NixHash here, which can also represent other hash types, and that had a bunch of annoyances: - Whenever we had the bytes, we had to wrap them in a NixHash::Sha256(). - Things like AtermWriteable had to be implemented on NixHash, even though we then had an assertion it was only called in the NixHash::Sha256 case.

2024-03-03 r/7633 fix(tvix/nix-compat): Make CAHash deserialize more formatsBrian Olsen1-0/+30
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.

2023-08-20 r/6512 refactor(tvix/nix-compat/nixhash): validate digest lengthsFlorian Klink2-10/+19
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 Lahfa1-1/+111
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.

This `.into_iter()` call is equivalent to `.iter()` and will not consume the `BTreeMap`. Change-Id: Ie26637ebecb0bea5b09c447cc45ed207f8b50913 Reviewed-on: https://cl.tvl.fyi/c/depot/+/9088 Autosubmit: flokli <flokli@flokli.de> Reviewed-by: raitobezarius <tvl@lahfa.xyz> Tested-by: BuildkiteCI
