Some paths might use names that are not valid UTF-8. We should be able to represent them. We don't actually need to touch the PathInfo structures, as they need to represent StorePaths, which come with their own harder restrictions, which can't encode non-UTF8 data. While this doesn't change any of the wire format of the gRPC messages, it does however change the interface of tvix_eval::EvalIO - its read_dir() method does now return a list of Vec<u8>, rather than SmolStr. Maybe this should be OsString instead?

2023-03-13 r/5964 refactor(tvix/eval): flatten call stack of VM using generatorsVincent Ambo2-291/+301
Warning: This is probably the biggest refactor in tvix-eval history, so far. This replaces all instances of trampolines and recursion during evaluation of the VM loop with generators. A generator is an asynchronous function that can be suspended to yield a message (in our case, vm::generators::GeneratorRequest) and receive a response (vm::generators::GeneratorResponsee). The `genawaiter` crate provides an interpreter for generators that can drive their execution and lets us move control flow between the VM and suspended generators. To do this, massive changes have occured basically everywhere in the code. On a high-level: 1. The VM is now organised around a frame stack. A frame is either a call frame (execution of Tvix bytecode) or a generator frame (a running or suspended generator). The VM has an outer loop that pops a frame off the frame stack, and then enters an inner loop either driving the execution of the bytecode or the execution of a generator. Both types of frames have several branches that can result in the frame re-enqueuing itself, and enqueuing some other work (in the form of a different frame) on top of itself. The VM will eventually resume the frame when everything "above" it has been suspended. In this way, the VM's new frame stack takes over much of the work that was previously achieved by recursion. 2. All methods previously taking a VM have been refactored into async functions that instead emit/receive generator messages for communication with the VM. Notably, this includes *all* builtins. This has had some other effects: - Some test have been removed or commented out, either because they tested code that was mostly already dead (nix_eq) or because they now require generator scaffolding which we do not have in place for tests (yet). - Because generator functions are technically async (though no async IO is involved), we lose the ability to use much of the Rust standard library e.g. in builtins. This has led to many algorithms being unrolled into iterative versions instead of iterator combinations, and things like sorting had to be implemented from scratch. - Many call sites that previously saw a `Result<..., ErrorKind>` bubble up now only see the result value, as the error handling is encapsulated within the generator loop. This reduces number of places inside of builtin implementations where error context can be attached to calls that can fail. Currently what we gain in this tradeoff is significantly more detailed span information (which we still need to bubble up, this commit does not change the error display). We'll need to do some analysis later of how useful the errors turn out to be and potentially introduce some methods for attaching context to a generator frame again. This change is very difficult to do in stages, as it is very much an "all or nothing" change that affects huge parts of the codebase. I've tried to isolate changes that can be isolated into the parent CLs of this one, but this change is still quite difficult to wrap one's mind and I'm available to discuss it and explain things to any reviewer. Fixes: b/238, b/237, b/251 and potentially others.

2023-02-02 r/5825 refactor(tvix/cli): use Wu-Manber string scanning for drv referencesVincent Ambo3-58/+34
Switch out the string-scanning algorithm used in the reference scanner. The construction of aho-corasick automata made up the vast majority of runtime when evaluating nixpkgs previously. While the actual scanning with a constructed automaton is relatively fast, we almost never scan for the same set of strings twice and the cost is not worth it. An algorithm that better matches our needs is the Wu-Manber multiple string match algorithm, which works efficiently on *long* and *random* strings of the *same length*, which describes store paths (up to their hash component). This switches the refscanner crate to a Rust implementation[0][1] of this algorithm. This has several implications: 1. This crate does not provide a way to scan streams. I'm not sure if this is an inherent problem with the algorithm (probably not, but it would need buffering). Either way, related functions and tests (which were actually unused) have been removed. 2. All strings need to be of the same length. For this reason, we truncate the known paths after their hash part (they are still unique, of course). 3. Passing an empty set of matches, or a match that is shorter than the length of a store path, causes the crate to panic. We safeguard against this by completely skipping the refscanning if there are no known paths (i.e. when evaluating the first derivation of an eval), and by bailing out of scanning a string that is shorter than a store path. On the upside, this reduces overall runtime to less 1/5 of what it was before when evaluating `pkgs.stdenv.drvPath`. [0]: Frankly, it's a random, research-grade MIT-licensed crate that I found on Github: https://github.com/jneem/wu-manber [1]: We probably want to rewrite or at least fork the above crate, and add things like a three-byte wide scanner. Evaluating large portions of nixpkgs can easily lead to more than 65k derivations being scanned for.

We only do logic here if algo and hash_mode are Some(_) (and there's an `out` output). The fact we don't do anything in all in other cases is a bit hidden at the bottom. Use if let for the destructuring, and drop the other case.

2023-01-27 r/5772 fix(tvix/cli): handle SRI hashes in outputHashFlorian Klink2-18/+140
Instead of being called with `md5`, `sha1`, `sha256` or `sha512`, `fetchurl.nix` (from corepkgs / `<nix`) can also be called with a `hash` attribute, being an SRI hash. In that case, `builtin.derivation` is called with `outputHashAlgo` being an empty string, and `outputHash` being an SRI hash string. In other cases, an SRI hash is passed as outputHash, but outputHashAlgo is set too. Nix does modify these values in (single, fixed) output specification it serializes to ATerm, but keeps it unharmed in `env`. Move this into a construct_output_hash helper function, that can be tested better in isolation.

2023-01-27 r/5769 feat(tvix/cli): implement `builtins.derivation`Vincent Ambo3-0/+41
This uses the actual upstream Nix code for `builtins.derivation` (which is not a primop in C++ Nix) to implement `builtins.derivation` as a wrapper around `builtins.derivationStrict`. We're doing it this way to ensure that our thunking logic is correct. An initial Rust-native rewrite (see e.g. cl/7363) is pretty difficult to debug while there are still other issues to root out, but eventually we might want to turn this into native code.
