2024-06-06 r/8222 feat(tvix): Switch to jemallocAspen Smith1-0/+6
Switch tvix to using jemalloc as the default global allocator on supported (eg, non-msvc) platforms. This gives a pretty reasonable performance boost basically for free: int time: [24.361 µs 24.386 µs 24.418 µs] change: [-19.355% -18.859% -18.527%] (p = 0.00 < 0.05) Performance has improved. merge small attrs time: [37.201 µs 37.328 µs 37.442 µs] change: [-24.609% -24.266% -23.982%] (p = 0.00 < 0.05) Performance has improved. merge large attrs with small attrs time: [20.030 ms 20.135 ms 20.251 ms] change: [-4.2811% -3.2549% -2.3807%] (p = 0.00 < 0.05) Performance has improved. hello outpath time: [967.91 ms 974.07 ms 983.33 ms] change: [-5.5008% -4.4552% -3.4099%] (p = 0.00 < 0.05) Performance has improved.

2024-05-11 r/8103 refactor(tvix/store): drop calculate_nar from PathInfoServiceFlorian Klink1-15/+9
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.

2024-02-21 r/7588 revert(tvix): don't use Rc::clone explicitlyaspen1-2/+2
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>
2024-02-20 r/7578 feat(tvix/eval): implement `builtins.filterSource`Ryan Lahfa1-2/+3
We add a new set of builtins called `import_builtins`, which will contain import-related builtins, such as `builtins.path` and `builtins.filterSource`. Both can import paths into the store, with various knobs to alter the result, e.g. filtering, renaming, expected hashes. We introduce `filtered_ingest` which will drive the filtered ingestion via the Nix function via the generator machinery, and then we register the root node to the path info service inside the store. `builtins.filterSource` is very simple, `builtins.path` is a more complicated model requiring the same logic albeit more sophisticated with name customization, file ingestion method and expected SHA-256.

Initialize a new empty builtins module `fetcher_builtins`, which will contain the builtins which fetch URLs from the internet: * fetchurl * fetchGit * fetchTarball * fetchTree (maybe? this is experimental) These builtins are all implemented in CPP nix at: https://github.com/NixOS/nix/blob/2.20.2/src/libexpr/primops/fetchTree.cc These builtins are added to the evaluation context using a similar mechanism to the derivation builtins, and have been added everywhere derivation builtins were previously being added.

2024-01-18 r/7410 feat(tvix/glue): use TvixStoreIO as derivation builtin stateRyan Lahfa1-12/+17
We propagate a `TvixStoreIO` as the `state` of our derivation-specific builtins in the glue crate. The evaluators `io_handle` itself is using a Rc<dyn EvalIO>. An earlier version of TvixStoreIO was also introducing generics over the different internal services themselves, but we opted for instead hardcoding this to Arc<dyn …> for the sake of less macro voodoo.

2024-01-03 r/7338 feat(tvix/glue): contextful derivationRyan Lahfa1-10/+7
We calculate the input context by performing the union of context over all input of the derivation. Then, we just pass the rest of it to the remaining machinery. Finally, we re-emit an `outPath` and a `drvPath` containing the expected contexts.

2023-12-31 r/7289 refactor(tvix/eval): remove code and location from structFlorian Klink1-2/+2
Instead, it's passed in the evaluate/compile_only functions, which feels more naturally. It lets us set up the Evaluation struct long before we actually feed it with data to evaluate. Now that Evaluation::new() would be accepting an empty list of arguments, we can simply implement Default, making things a bit more idiomatic.

2023-12-12 r/7161 feat(tvix/glue): add nixpkgs eval benchmarkFlorian Klink1-0/+68
This adds a criterion.rs-based testbench into tvix-glue. It can be invoked by running `cargo bench` from inside the `tvix-glue` crate. `target/criterion/report/index.html` contains nice graphs. It's able to diff against the previous run, so you can invoke `cargo bench` before and after a certain change to reason about the impact in evaluation performance. Currently, we need to create a bunch of Evaluator resources inside the benchmark loop itself, which is a bit annoying, as it leaks into the things we benchmark. This should become better with b/262. Fixes b/322.
