2022-12-21 r/5459 feat(tvix/eval): add EvalIO to public crate APIVincent Ambo6-14/+42
This lets users set the `io_handle` field on an `Evaluation`, which is then propagated to the VM. Change-Id: I616d7140724fb2b4db47c2ebf95451d5303a487a Reviewed-on: https://cl.tvl.fyi/c/depot/+/7566 Reviewed-by: grfn <grfn@gws.fyi> Tested-by: BuildkiteCI
2022-12-21 r/5458 feat(tvix/eval): introduce initial EvalIO traitVincent Ambo2-0/+53
This trait is going to be used to abstract filesystem interactions in Tvix. For now, it only contains a `read_to_string` method that closely mirrors `std::fs::read_to_string`. As a first step, to see how this works in practice, we will thread through only this function to the various relevant parts. Two implementations are provided in tvix-eval itself: A dummy implementation (which just returns ErrorKind::NotImplemented for all operations), and a std implementation which delegates to `std` functions.

2022-12-21 r/5457 refactor(tvix/eval): add a LightSpan type for lighter span trackingVincent Ambo5-12/+61
This type carries the information required for calculating a span (i.e. the chunk and offset), instead of the span itself. The span is then only calculated in cases where it is required (when throwing errors). This reduces the eval time for `builtins.length (builtins.attrNames (import <nixpkgs> {}))` by *one third*! The data structure in chunks that carries span information reduces in-memory size by trading off the speed of retrieving span information. This is because the span information is only actually required when throwing errors (or emitting warnings). However, somewhere along the way we grew a dependency on carrying span information in thunks (for correctly reporting error chains). Hitting the code paths for span retrieval was expensive, and carrying the spans in a different way would still be less cache-efficient. This change is the best tradeoff I could come up with.

2022-12-21 r/5454 refactor(tvix/eval): add name-based index over compiler's localsVincent Ambo2-34/+108
Instead of finding locals by doing 2x O(n) walks over the compiler's locals list, use a secondary name-based index for resolving locals by name. Previously, almost 60% (!!) of eval time on some expressions over nixpkgs was spent in `Local::has_name`. This function doesn't even exist anymore now, and eval speed about doubles as a result. Note that this doesn't exactly make the locals code easier to read, but I'm also not sure what we can simplify in there in general. This fixes b/227.

2022-12-21 r/5440 refactor(tvix): split binary (REPL etc.) out from evaluator libraryVincent Ambo9-198/+105
The tvix-eval project is independent from any *uses* of the evaluator, such as the tvix-repl. This functionality has been split out into a separate "tvix-cli" crate. Note that this doesn't have to mean that this CLI crate is the "final" CLI crate for tvix, the point of this is not "getting the CLI structure right" but rather "getting the evaluator structure right". This reshuffling is part of restructuring the way that functionality like store communication is injected into language evaluation. Note that at this commit the new CLI crate is not at feature-parity.

2022-12-21 r/5438 feat(tvix/eval): begin introducing new public APIVincent Ambo1-2/+154
A step towards something more like how I imagine the future public API for tvix-eval. Please note that this is definitely not the final version yet, but it's better than the previous API that either exposed a side-effecting blackbox, or a very low-level "interface". The basic idea is that an evaluation of some Nix code is requested by a caller with various parameters, but not all callers are interested in all of these parameters. There are also some bits of information that are returned from an evaluation that are not necessarily relevant to all callers. To support this somewhat ergonomically, the API is built around an `Evaluation` struct that is configured by the caller with the various parameters and then "executed".

2022-12-15 r/5420 refactor(tvix): build Rust projects using crate2nixVincent Ambo11-56/+6345
Introduces granular dependency builds using crate2nix, bootstrapped off the generated configuration from the newly introduced workspace (see cl/7533). This commit checks in the generated Cargo.nix file which can be regenerated with a parameterless invocation of `crate2nix generate` in `//tvix`. I tried generating this in IFD, but it turned out to be harder than what seemed worthwhile for now. In this setup, the various build targets for Rust projects end up being attributes of the imported `Cargo.nix` file at the `tvix.crates` attribute. These still lack configuration, however, which has been fixed in the various `default.nix` files of individual projects. Note that we (temporarily) lose the ability to build tvix-eval's benchmarks in CI. I haven't figured out what magic incantation summons them from the void again ... The `eval-okay-readDir` tests from both test suites have been disabled because they fail for unknown reasons when run in this new derivation. Somebody will have to debug it!

2022-12-15 r/5419 refactor(tvix): share a Cargo.lock file between Rust projectsVincent Ambo10-1707/+262
This relates to the (abandoned) cl/7256. Introduces a Cargo workspace at //tvix that is primarily intended to be used as a workaround for the annoying Nix+Rust tooling while having a consistent set of dependencies. This is driven in part by a desire to adopt crate2nix and get more granular Nix builds for Tvix's Rust projects, and in part by a need to split //tvix/eval into something providing the CLI (REPL etc.), and a library providing eval, without significantly altering the structure of build targets. To accomplish this the workspace has been designed to allow projects to remain independent build targets. I want to avoid lumping all the projects together - something like //tvix/eval should always be independent of other parts of tvix. A helper function in //tvix/default.nix lets downstream naersk projects construct a sparse root for the project which combines the workspace's `Cargo.lock` with the project's own `Cargo.toml`. Note that cargo commands in the workspace itself require the build dependencies of _all_ projects to be present, which is currently a bit annoying to accomplish. This introduces some breakage: 1. It breaks usage of rust-analyser without being in a shell with the dependencies of *all* Tvix projects, as it is not capable of respecting only the subset of dependencies for a part of the workspace. 2. It is no longer possible to run tests using `cargo test`, as the test generation crate we use does not work with workspaces: https://github.com/frehberg/test-generator/issues/6 This still works in the Nix build as we construct a Cargo project that looks like it's not in a workspace there. Until somebody fixes that crate / writes a new macro / does something else with the test suite, the way to run the tests is through the Nix build. Long-term we'll probably want to get rid of cargo completely, it's just a big wart and most tooling works without it if correctly configured, but we don't have time for that now.

2022-12-15 r/5418 fix(tvix): remove disruptive .envrc fileVincent Ambo1-7/+0
This .envrc file causes additional software to be loaded, but there is no way to opt-out even if the software is not desired: 1. If I opt-in (i.e. `direnv allow`) the file, additional stuff that I don't need is injected into my environment in a blocking way. 2. If I opt-out, *all* of the depot configuration (including `mg`) is unloaded, as direnv configurations do not trivially nest. I have to work around this constantly by making the file contain just the line `source_up` and then setting `--assume-unchanged` on the git index to avoid accidentally committing the file changes. This is kind of silly, the people who *want* this stuff to be loaded should devise a mechanism that loads it automatically but is opt-in. This could be done e.g. by gating something on environment variables, or having a shell hook, or whatever. Breaking expectations that hold elsewhere in depot is not okay, however. If you manually want a shell for a project, run `mg shell` either with a target specification for that project (e.g. `mg shell //tvix/store`) or in the project's folder. You can also just use standard nix-shell invocations.

2022-11-26 r/5340 feat(tvix/eval): use backtrace-on-stack-overflow crateAdam Joseph3-116/+238
The backtrace-on-stack-overflow create provides best-effort stack traces when a stack overflow happens. Since it's running on the (usually tiny) signal alternate stack this isn't easy. This is guarded by a new `backtrace_overflow` feature flag and never enabled (even if that feature is selected) for release builds. This is strictly for debugging; there's crazy unsafe voodoo in there. https://lib.rs/crates/backtrace-on-stack-overflow Example output: ``` Stack Overflow: 0: backtrace_on_stack_overflow::handle_sigsegv at /home/amjoseph/.cargo/registry/src/github.com-1ecc6299db9ec823/backtrace-on-stack-overflow-0.2.0/src/lib.rs:93:40 1: <unknown> 2: __rust_probestack 3: tvix_eval::vm::VM::run_op at src/vm.rs:399 4: tvix_eval::vm::VM::run at src/vm.rs:388:23 5: tvix_eval::vm::VM::enter_frame at src/vm.rs:360:22 6: tvix_eval::value::thunk::Thunk::force at src/value/thunk.rs:116:25 7: tvix_eval::vm::VM::run_op at src/vm.rs:801:37 8: tvix_eval::vm::VM::run at src/vm.rs:388:23 9: tvix_eval::vm::VM::enter_frame at src/vm.rs:360:22 10: tvix_eval::value::thunk::Thunk::force at src/value/thunk.rs:116:25 ... ``` Signed-off-by: Adam Joseph <adam@westernsemico.com> Change-Id: I1d8a2017f836be7bf91a2223e7adacb86fa1dbb2 Reviewed-on: https://cl.tvl.fyi/c/depot/+/7354 Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>
