2023-01-20 r/5715 refactor(tvix/eval): keep globals alive through VM structVincent Ambo2-7/+42
This forces users to pass the fully constructed set of globals to the VM, making it harder to accidentally "lose" the set while weak references to it still exist. This doesn't modify any functionality, but is laying the foundation for simplifying some of the builtins behaviour that has grown more complex again.

2023-01-20 r/5706 feat(tvix/eval): add error contexts to annotate error kindsVincent Ambo1-4/+2
This makes it possible for users to add additional context to an error, which will then be rendered as an additional secondary span in the formatted error output. We should strive to do this basically anywhere errors are raised that can occur multiple times, *especially* during type casts. This was triggered by me debugging a type cast error attached to a fairly large-ish span (a builtin invocation).

2023-01-17 r/5676 refactor(tvix/eval): non-hacky suspended native thunksVincent Ambo1-55/+35
Instead of having a representation of suspended native thunks that involves constructing a fake code chunk, make these thunks a first-class part of the internal thunk representation. The previous code was not that simple to understand, and actually contained a critical bug which could lead to Tvix crashes. This version fixes the particular instance of that bug, but instead uncovers another (b/238) which can still lead to Tvix crashes. Fixes: b/237.

Instead of going through Vec/BTreeMap for generating our internal types, use the proptest strategies from imbl. The one thing I couldn't figure out in the previous implementation is where the ranges/sizes of generated collections came from. The strategies in proptest use different types (Range, with an unknown default value, and SizeRange with 0..100). I've opted to specify 0..100 directly, but we can probably make it configurable.

The `im::OrdMap` is already small and cheap to copy while sharing memory, so this is not required anymore.

This uses the `im::OrdMap` for `NixAttrs` to enable sharing of memory between different iterations of a map. This slightly speeds up eval, but not significantly. Future work might include benchmarking whether using a `HashMap` and only ordering in cases where order is actually required would help. This switches to a fork of `im` that fixes some bugs with its OrdMap implementation.

The conversion from im::Vector -> Vec is cheaper for NixList construction (of course), so where possible we should make use of that. This updates most builtins dealing with lists to use Vector directly, and marks the function constructing NixList from Vec as deprecated so that we get appropriate warnings in places where it's still in use. These places are currently inside of JSON serialisation logic which is in flux right now, so lets leave them as-is until it's stabilised.

This is a persistent, structurally sharing data structure which is more efficient in some of our use-cases. I have verified the efficiency improvement using `hyperfine` repeatedly over expressions on nixpkgs. Lists are not the most performance-critical structure in Nix (that would be attribute sets), but we can already see a small (~5-10%) improvement. Note that there are a handful of cases where we still go via `Vec` that need to be fixed, most notable for `builtins.sort` which can not currently be implemented directly using `im::Vector` because of a restrictive type bound.

2022-12-21 r/5457 refactor(tvix/eval): add a LightSpan type for lighter span trackingVincent Ambo1-9/+12
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.

When we start unrecursivifying (sp?) things, Rust's borrow checker is going to be a headache; its magic only works when you use the CPU stack as your call stack. Fixing the borrow checker issues usually involves adding lots of `clone()`s. Right now `NixList` is the only variant of `Value` that isn't cheap to clone() -- all the others are either a wrapper around Rc or else are of bounded size. Note that this requires dropping the `DerefMut for NixList` instance and using `Vec<Value>` instead in those situations.

2022-11-08 r/5268 feat(tvix/eval): Give names to builtin argumentsGriffin Smith2-10/+16
Refactor the arguments of a Builtin to be a vec of a new BuiltinArgument struct, which contains the old strictness boolean and also a static `name` str - this is automatically determined via the ident for the corresponding function argument in the proc-macro case, and passed in in the cases where we're still manually calling Builtin::new. Currently this name is unused, but in the future this can be used as part of a documentation system for builtins.

2022-11-05 r/5250 refactor(tvix/eval): rename Opcode::DataLocalIdx to DataStackIdxAdam Joseph1-1/+1
It is very confusing that this opcode is called DataLocalIdx, but it carries a StackIdx rather than a LocalIdx. It seems like this really ought to be called DataStackIdx, but maybe I've misunderstood; if so please explain it to me.

2022-11-04 r/5241 fix(tvix/eval): quote keys which are not valid identifiersAdam Joseph1-1/+24
The impl Display for NixAttrs needs to wrap double quotes around any keys which are not valid Nix identifiers. This commit does that, and adds a test (which fails prior to this commit and passes after this commit).

2022-11-04 r/5236 fix(tvix/eval): remove impl PartialEq for ValueAdam Joseph6-22/+29
It isn't possible to implement PartialEq properly for Value, because any sensible implementation needs to force() thunks, which cannot be done without a `&mut VM`. The existing derive(PartialEq) has false negatives, which caused the bug which cl/7142 fixed. Fortunately that bug was easy to find, but a silent false negative deep within the bowels of nixpkgs could be a real nightmare to hunt down. Let's just remove the PartialEq impl for Value, and the other derive(PartialEq)'s that depend on it.

2022-10-31 r/5226 fix(tvix/eval): nix_eq() must recurseAdam Joseph1-3/+3
The current implementation of nix_eq will force one level of thunks and then switch to the (non-forcing) rust Eq::eq() method. This gives incorrect results for lists-of-thunks. This commit changes nix_eq() to be recursive. A regression test (which fails prior to this commit) is included. This fix also causes nix_tests/eval-okay-fromjson.nix to pass, so it is moved out of notyetpassing.

2022-10-29 r/5222 feat(tvix/eval): Implement builtins.sortGriffin Smith1-1/+7
This is a bit tricky because the comparator can throw errors, so we need to propagate them out if they exist and try to avoid sorting forever by returning a reasonable ordering in this case (as short-circuiting is not available).
