2023-03-13 r/5967 refactor(tvix/eval): simplify NixString representation(s)Vincent Ambo3-65/+37
Instead of the two different representations (which we don't really use much), use a `Box<str>` (which potentially shaves another 8 bytes off `Value`). NixString values themselves are immutable anyways (which was a guarantee we already had with `SmolStr`), so this doesn't change anything else.

2023-03-13 r/5966 refactor(tvix/eval): wrap NixList in RcVincent Ambo2-14/+16
The size of a `Vector<Value>` is 64 *bytes*, which is quite large, and it bloated the entire Value type to this size. This change adds an indirection for the inner vector through Rc. Initially I tried to use a Box, but this breaks pointer equality guarantees for the Vector when it is small enough to be inlined. This reduces the size of Value from 64 to 32 bytes.

2023-03-13 r/5964 refactor(tvix/eval): flatten call stack of VM using generatorsVincent Ambo24-2677/+2500
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.

2023-03-13 r/5963 feat(tvix/eval): implement generator-based Nix equality logicVincent Ambo2-6/+182
Adds a `Value::neo_nix_eq` method (the `neo_` prefix will be dropped when we flip over to the generator implementation of the VM) which implements Nix equality semantics using async, generator-based comparisons. Instead of tracking the "kind" of equality that is being compared (see the pointer-equality doc) through a pair of booleans, I've introduced an enum that explicitly lists the possible comparisons.

2023-03-13 r/5961 feat(tvix/eval): implement asynchronous list sorting algorithmVincent Ambo1-0/+47
In order to implement an asynchronous builtins.sort (required for moving builtins to generators), we need an `async` sorting algorithm as our comparators involve invoking a Nix function. This commit implements a fairly simple, optimised bubble sort as the sorting algorithm used in our `async fn sort_by`. There don't seem to be any crates providing async versions of things like this, and they might actually be pretty hard to implement generically due to some constraints about how `async` works. Note that this algorithm is less efficient than the hybrid "timsort/mergesort/insert sort" used in the Rust standard library. I tried to write a merge sort implementation, but ran into isuses with the sort becoming unstable because our comparators can not yield equality. This is the simplest implementation which I know to be correct. Note that as of this commit this is *not* covered by the Tvix test suite, but it will be as soon as the rest of the generator code lands.

This was the last piece of code using BlobWriter. We can also use `read_all_and_chunk`, it's just requires a bit more plumbing: - The data coming from the client (stream) needs to be mapped (we extract the .data field). - The stream needs to be turned into an (async) reader - The reader needs to be made sync, and that code using the sync reader needs to be in a `task::spawn_blocking`.

This allows hiding to tests what exact implementation we're using, when testing things that do something with a store, but don't care what's used for underlying storage.

2023-03-10 r/5926 feat(tvix/store): do not buffer blob dataFlorian Klink2-73/+139
Use the FastCDC::cut function to ask fastcd for cutting points as we receive the data. Make sure to keep the last chunk in the temporary buffer, as we might not actually cut at the end. Also, use rayon to calculate the blake3 hash if the input data is > 128KiB.

2023-03-10 r/5925 feat(tvix/store): bump fastcdc, use v2020 versionFlorian Klink4-6/+6
This switches away from the less canonical "ronomon" version to the implementation as described in the [paper](https://ieeexplore.ieee.org/document/9055082) by Wen Xia, et al., in 2020. That version uses 64-bit hash values and tends to be faster than both the ronomon and v2016 versions, and produces the same chunking as the 2016 version. As per https://docs.rs/fastcdc/latest/fastcdc/#implementations-1, it's the recommended choice. The crate also gained support for streaming version of chunkers: https://docs.rs/fastcdc/latest/fastcdc/#large-data, which might be useful.
