2024-03-16 r/7701 fix(tvix): don't emit rerun-if-changedFlorian Klink3-6/+6
`build.rs` emits rerun-if-changed statements for all proto files, as well as all include paths we pass it. Unfortunately, due to protobufs include path rules, we need to specify the path to the depot root itself as an include path, at least when building impurely with `cargo`. This causes cargo to essentially always rebuild, as it also puts its own temporary files in there. Unfortunately, tonic-build does not chase down to individual .proto files that are included. Disable emitting these `rerun-if-changed` statements for now. This could cause cargo to not rebuild protos every time, causing stale data until the next local `cargo clean`, but considering the protos change not that frequently, and it'll immediately surface if trying to build via Nix (either locally or in CI), it's a good-enough compromise.

2024-03-15 r/7695 feat(nix-compat/wire): add low-level wire format primitives codeFlorian Klink6-4/+157
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.

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.

2024-03-11 r/7678 feat(tvix/glue): Implement builtins.fetchurlAspen Smith11-54/+454
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.

This change makes deserialize support any digest format (so hex, nixbase32 and base64) as well as flattens the deserialize code and error handling.

2024-02-29 r/7625 feat(tvix/eval): implement `builtins.hashFile`Padraic-O-Mhuiris6-25/+42
The primary addition is the `builtin_hashFile` function which attempts value-path coercion and on success reads the file to a nix_string. Similar to the `builtins_hashString` implementation, the hash is then derived using the `hash_nix_string` function in the introduced hash module which has extracted hashing functionality initially specified in cl/11005.

2024-02-21 r/7591 feat(tvix/eval): Store string context alongside dataAspen Smith9-79/+377
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.

This reverts commit d9565a4d0af3bffd735a77aa6f1fd0ec0e03b14a. Reason for revert: this was intentional - putting Rc::clone instead of .clone is a common Rust idiom, and makes it explicit that we're cloning a shared reference, not an underlying resource Change-Id: I41a5f323ee35d7025dc7bb02f7d5d05d0051798d Reviewed-on: https://cl.tvl.fyi/c/depot/+/10995 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de>
