2022-09-22 r/4958 fix(tvix/eval): support string identifiers in inheritsVincent Ambo1-61/+89
This updates rnix-parser to a version where inherits provide an iterator over `ast::Attr` instead of `ast::Ident`, which mirrors the behaviour of Nix (inherits can have (statically known) strings as their identifiers). This actually required some fairly significant code reshuffling in the compiler, as there was an implicit assumption in many places that we would have an `ast::Ident` node available when dealing with variable access (which is then explicitly only not true in this case).

2022-09-18 r/4907 refactor(tvix/eval): clone the Arc<codemap::File> for the compilerVincent Ambo1-5/+6
This disconnects ownership of the `File` reference in a compiler from the calling scope, which is required for when we implement `import`. `import` will need to carry an `Rc<RefCell<CodeMap>>` (or maybe, in the future, Arc) to give us the ability to add new detected code files at runtime. Note that the choice of `Arc` over `Rc` here is not ours - it's the codemap crate's.

This trait can be used to convert most structures from rnix-parser into a codemap::Span. It uses a macro to implement the trait for the various expression types in the rnix AST, as Rust's silly semantic versioning restriction stops us from doing a blanket implementation. This will be used in the next commit to clean up the span handling in the compiler a bit.

Yep. This is kind of ugly right now. The idea is that the recursive_scope compilation function is used for recursive sets as well by emitting the keys. The rest of the logic is pretty much identical. There is quite a lot of code here that can be cleaned up (duplication between attrs and let, duplication inside of the recursive scope compilation function etc.), but I'd like to get it working first and then make it nice. Note that nested keys are *not* supported yet.

With this puzzle piece of string compilation in place, `compile_str` becomes less redundant, as every part now needs to be compiled the same. The thunking logic becomes a bit trickier, since we need to thunk even in the case of `count == 1` if the single part is interpolating. Splitting the inner (shared) code in a separate function turned out to be easier for making rustc content.

If we have multiple string parts, we need to thunk assembling the string. If we have a single literal, it is strict (like all literals), but a single interpolation part may compile to a thunk, depending on how the expression inside is compiled – we can avoid forcing to early here compared to the previous behavior. Note that this CL retains the bug that `"${x}"` is erroneously translated to `x`, implying e.g. `"${12}" == 12`. The use of `parts.len()` is unproblematic, since normalized_parts() builds a `Vec` instead of returning an iterator.

This very closely follows the way it's done for warnings, but errors have a lot more information available in some cases which we do not surface yet. Note also that due to requiring the `CodeMap`, this is not yet called from eval.rs as the way that is threaded through needs to be refactored, so only the method for reporting these errors as strings is implemented so far. Next steps for this will be to add a generic diagnostics module that reduces some of the boilerplate for this between warnings & errors, and which will also give us a good point in the future to switch to a fancier diagnostics crate.

Refactors the methods used for determining whether an identifier in a binding (i.e. an `rnix::Attr` node) is a static string, and extracting it. Previously all uses of this logic were for `let`-expressions, where dynamic attributes are always an error. However, we need the same logic to properly implement the phase separation of attribute set compilation. To facilitate this, the actual core logic of these methods now return `Option`, and are only converted to errors in cases where the errors are actually required.

We need to make sure that we compile all plain inherits in a let expression before declaring any other locals. Plain inherits are special in the sense that they can never be recursive, instead resolving to a higher scope. Thus we need to compile their value, before declaring them. If we don't do that, before any other local can be declared, we cause a situation where the plain inherits' values are placed into other locals' stack slots. Note that we can't integrate the plain inherit compilation into the regular 2-3 phase model where we defer the compilation of the value or we'd compile `let inherit x; in …` as `let x = x; in …`.

2022-09-11 r/4805 fix(tvix/eval): declare let inherit (from) locals before compilingsterni1-47/+49
The recent change that split declaration of let based locals and the compilation of their values did not touch locals bound by inherit in let. These were previously declared and compiled immediately before starting to work on the other locals introduced in a let. In the case of plain inherits, this behavior is kept in this change, because there's nothing wrong with it: The value of a plain inherit will always resolve to a higher scope, either statically or dynamically. Since inherit (from) expression might refer to other locals bound in the same let, we need to handle them in the same three steps as ordinary let based locals: 1. We need to declare the (uninitialised) locals. 2. We need to compile the expression that obtains their value. For this, we create a new thunk, since the from expression may very well return a thunk which we need to force before selecting the value we are interested in. 3. Thunks need to be finalised. For 1., we create an extra pass over the inherits that already declares and initialises plain inherits and notes inherit (from) expressions in the entries vector after declaring them. 2. only needs a bit of adapting to create the thunks for selecting if appropriate, the rest of the existing code can be reused.

2022-09-08 r/4770 feat(tvix/eval): thunk binary operations and select expressionsVincent Ambo1-2/+14
With this, most cases of `fix` in attribute sets will work correctly. A simple test exercising both has been added. Change-Id: I70fd431177bb6e48ecb33a87518b050c4c3d1c09 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6437 Reviewed-by: sterni <sternenseemann@systemli.org> Tested-by: BuildkiteCI
2022-09-08 r/4768 feat(tvix/eval): print lambda memory adresses in disassemblerVincent Ambo1-15/+10
This makes it easier to track exactly which lambda is which when inspecting e.g. the concrete representation of a thunk. At runtime all lambdas live in an Rc. To make this print the right address, the construction of these Rcs had to be moved up right to the point where the lambda is first emitted (and disassembled).

2022-09-08 r/4762 fix(tvix/eval): consider local depth when deciding to deferVincent Ambo1-5/+8
Deferred local upvalues can *only* occur at the same depth as the thing that is closing over them, but there are various situations with scope nesting where the actual stack indexes of the local and the closer look like a deferred value is being accessed. To fix this, simply compare the depth as well.

2022-09-08 r/4760 refactor(tvix/eval): clean up logic in Compiler::end_scopeVincent Ambo1-5/+3
The condition here was extremely hard to read prior to this change. As the locals vector is now guaranteed to never be empty (there is always at least a phantom for the current chunk's root expression), the logic here can be simplified to just dropping tailing locals entries while their depth matches that of the scope being closed.
