2024-08-28 r/8602 fix(tvix/nix-compat-derive): Get rid of external feature flagBrian Olsen5-56/+3
The external feature flag was there because I couldn't find a way to refer to crate and nix-compat with the same name so that the generated code could be the same. In essence `use nix_compat::nix_daemon::de::NixDeserialize` is an error when used inside nix_compat crate. So my best fix was the external feature flag until I found the solution used here which also removes the flag completely.

tonic-reflection 0.12.x moved from the v1alpha to v1 of the reflection protocol. However, most clients, like Postman, Kreya and evans don't support that one yet.

2024-08-21 r/8547 feat(nix-compat/nix_http): init parse_nar[info]_strFlorian Klink13-104/+433
This moves the URL component parsing code we had in nar-bridge to nix-compat. We change the function signature to return an Option, not a Result<_, StatusCode>. This allows returning more appropriate error codes, as we can ok_or(…) at the callsite, which we now do: on an upload to an invalid path, we now return "unauthorized", while on a GET/HEAD, we return "not found". This also adds support to parse compression suffixes. While not supported in nar-bridge, other users of nix-compat might very well want to parse these paths. Also fix the error message when parsing NAR urls, it mentioned 32, not 52, which is a copypasta error from the narinfo URL parsing code.

2024-08-20 r/8545 refactor(nix-compat/store_path): make StorePath generic on SFlorian Klink15-294/+280
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.

Tests are added for this new feature for a positive and a negative check. In addition, a path validation test was added.

2024-08-19 r/8540 feat(nix-compat/narinfo/signature): generalize name fieldFlorian Klink9-45/+117
Requiring `name` to be a `&str` means it'll get annoying to pass around `Signature`, but being able to pass them around in an owned fashion is kinda a requirement for a stronger typed `PathInfo` struct, where we want to have full ownership. Rework the `Signature` struct to become generic over the type of the `name` field. This means, it becomes possible to have owned versions of it. We don't want to impose `String` or `SmolStr` for example, but want to leave it up to the nix-compat user to decide. Provide a type alias for the existing `&str` variant (`SignatureRef`), and use it where we previously used the non-generic `Signature` one. Add some tests to ensure it's possible to *use* `Signature` with both `String` and `SmolStr` (but only pull in `smol_str` as dev dependency for the tests). Also, add some more docstrings, these were a bit sparse.

2024-08-19 r/8520 refactor(tvix/eval): remove use of imbl::VectorVincent Ambo4-47/+46
This vector type has served us well for now, but it contains internal refcounts which are incompatible with upcoming changes related to garbage collection. The performance impact of this change within all benchmarks I ran was within the margin of error: [nix-shell:/tmp/perf]$ hyperfine "./before -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings" Benchmark 1: ./u64 -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 7.528 s ± 0.272 s [User: 6.578 s, System: 0.631 s] Range (min … max): 7.160 s … 8.012 s 10 runs nix-shell:/tmp/perf]$ hyperfine "./std-vec -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings" Benchmark 1: ./std-vec -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 7.515 s ± 0.178 s [User: 6.508 s, System: 0.652 s] Range (min … max): 7.276 s … 7.861 s 10 runs Change-Id: Ib95f871956e336a1e5771f6293583854b1efb276 Reviewed-on: https://cl.tvl.fyi/c/depot/+/12197 Reviewed-by: aspen <root@gws.fyi> Tested-by: BuildkiteCI
2024-08-19 r/8519 refactor(tvix/eval): ensure VM operations fit in a single byteVincent Ambo12-572/+771
This replaces the OpCode enum with a new Op enum which is guaranteed to fit in a single byte. Instead of carrying enum variants with data, every variant that has runtime data encodes it into the `Vec<u8>` that a `Chunk` now carries. This has several advantages: * Less stack space is required at runtime, and fewer allocations are required while compiling. * The OpCode doesn't need to carry "weird" special-cased data variants anymore. * It is faster (albeit, not by much). On my laptop, results consistently look approximately like this: Benchmark 1: ./before -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 8.224 s ± 0.272 s [User: 7.149 s, System: 0.688 s] Range (min … max): 7.759 s … 8.583 s 10 runs Benchmark 2: ./after -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 8.000 s ± 0.198 s [User: 7.036 s, System: 0.633 s] Range (min … max): 7.718 s … 8.334 s 10 runs See notes below for why the performance impact might be less than expected. * It is faster while at the same time dropping some optimisations we previously performed. This has several disadvantages: * The code is closer to how one would write it in C or Go. * Bit shifting! * There is (for now) slightly more code than before. On performance I have the following thoughts at the moment: In order to prepare for adding GC, there's a couple of places in Tvix where I'd like to fence off certain kinds of complexity (such as mutating bytecode, which, for various reaons, also has to be part of data that is subject to GC). With this change, we can drop optimisations like retroactively modifying existing bytecode and *still* achieve better performance than before. I believe that this is currently worth it to pave the way for changes that are more significant for performance. In general this also opens other avenues of optimisation: For example, we can profile which argument sizes actually exist and remove the copy overhead of varint decoding (which does show up in profiles) by using more adequately sized types for, e.g., constant indices. Known regressions: * Op::Constant is no longer printing its values in disassembly (this can be fixed, I just didn't get around to it, will do separately).

The boot tests are sometimes flaky, and we don't want them to periodically fail other build. Have Buildkite auto-retry them 2 times on failure. Logs for individual failures are still available, so it won't hinder flakiness debuggability. See https://buildkite.com/docs/pipelines/command-step#retry-attributes for a documentation of a parameter, and cl/8983 for the introduction of that feature to //nix/buildkite.
