The `im::OrdMap` is already small and cheap to copy while sharing memory, so this is not required anymore. Only the `KV` variant may have slightly larger content, but in practice this doesn't seem to make a difference when comparing the two variants and this one is less complicated.

2022-12-29 r/5541 refactor(tvix/eval): persistent, memory-sharing OrdMap for NixAttrsVincent Ambo1-1/+1
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.

To work around this we clone the values for now. There might be some optimisations possible like checking for thunk equality directly and short-circuiting on that (we have to check what Nix does).

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.

Lists are compared lexicographically in C++ nix as of [0], and our updated nix test suites depend on this. This implements comparison of list values in `Value::nix_cmp` using a very similar algorithm to what C++ does - similarly to there, this requires passing in the VM so we can force thunks in the list elements as we go.

This is done via a new `deepForce` function on Value. Since values can be cyclical (for example, see the test-case), we need to do some extra work to avoid RefCell borrow errors if we ever hit a graph cycle: While deep-forcing values, we keep a set of thunks that we have already seen and avoid doing any work on the same thunk twice. The set is encapsulated in a separate type to stop potentially invalid pointers from leaking out. Finally, since deep_force is conceptually similar to `VM::force_for_output` (but more suited to usage in eval since it doesn't clone the values) this removes the latter, replacing it with the former.

2022-10-10 r/5087 feat(tvix/eval): Initial resolution of `<...>` pathsGriffin Smith1-4/+4
This commit implements (lazy) resolution of `<...>` paths via either the NIX_PATH environment variable, or the -I command-line flag - both handled via EvalOptions. As a result, EvalOptions can no longer derive Copy, meaning we have to clone it at each line of the repl - this is probably not a huge deal as repl performance is not exactly an inner loop and we're not cloning very much. Internally, this works by creating a thunk which pushes a constant containing the string inside the brackets to the stack, then a new opcode to resolve that path via the `NixPath`. To get that opcode to work, we now have to pass in the NixPath when constructing the VM. This (intentionally) leaves out proper implementation of path resolution via `findFile` (cppnix just calls whatever identifier called findFile is in scope!!!) as that's widely considered a bit of a misfeature, but if we do decide to implement that down the road it likely wouldn't be more than a few extra ops within the thunk introduced here.

2022-10-10 r/5085 feat(tvix/eval): Allow adding strings to pathsGriffin Smith1-0/+6
Implement adding paths and strings via OpAdd. Since the nix rules are quite obscure, I'm electing to test this one with an oracle test to avoid the danger of getting the actual asserted result wrong.

Factor out the construction of Value::Attrs (including the Rc) into a new `attrs` constructor function, to abstract away the presence of the Rc itself.

2022-09-29 r/4990 chore(tvix/eval): remove existing nested key implementationVincent Ambo1-5/+1
This implementation, which only ever worked for non-recursive attribute sets, is no longer needed and thus removed here. We have a new implementation of these nested keys coming up instead.

2022-09-20 r/4943 refactor(tvix/eval): add VM::call_value helper methodVincent Ambo1-17/+3
This makes it possible to call a callable value (builtin or closure/lambda) directly, without unwrapping it first. This is needed for pretty much all higher-order functions to work correctly. This is mostly equivalent to the previous code in coerce_to_string for calling `__toString`, except it expects the argument(s) to already be placed on the stack. Note that the span for the `NotCallable` error is not currently guaranteed to make any sense, will experiment with this.
