2022-09-11 r/4823 refactor(tvix/eval): remove `todo!()` calls in compilerVincent Ambo1-3/+18
It is impossible for tvixbolt to recover from panics, so the user experience of typing an expression using an unsupported feature was that it would get sad and stop responding to input. Instead, raise a normal value-level error of a new variant and continue where possible.

2022-09-11 r/4811 refactor(tvix/eval): refactor methods for parsing static identsVincent Ambo1-22/+39
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.

2022-09-11 r/4809 fix(tvix/eval): place plain inherits in correct stack slotssterni1-27/+41
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.

This completely rewrites the handling of "dynamic upvalues" to, instead of resolving them at thunk/closure instantiation time (which forces some values too early), capture the entire with stack of parent contexts if it exists.

Similar to setting up a phantom slot when compiling the root value of a file, closures and thunks need to have a phantom stack slot for the root of the expression yielded by their thunk to make all accounting work correctly. The tricky thing here is that closures & thunks *escape* their inner lambda context (that's the point!), so the functions emitting them need to know both the *inner* slot (to resolve everything correctly while compiling the slot) and the *outer* slot (to correctly emit instructions for closing over upvalues).

Instead of using sentinel values and an additional bool, this tracks the identifier of a local as an enum that is either a statically known name, or a phantom.

Phantom values are now not initialised by default, but the only current call site of phantoms (`with` expression compilation) performs the initialisation right away. This commit changes no actual functionality right now, but paves the way for fixing an issue related to `let` bodies.

2022-09-08 r/4741 feat(tvix/eval): ensure all errors always carry a spanVincent Ambo1-8/+9
Previously error spans were optional because the information about code spans was not available at runtime. Now that this information has been added, the error type will always carry a span. This change is very invasive all throughout the codebase. This is due to the fact that many functions that are called *by* the VM expected to return `EvalResult`, but this no longer works as the span information is not available to those functions - only to the VM itself. To work around this the majority of these functions have been changed to return `Result<T, ErrorKind>` instead and an accompanying macro in the VM constructs the "real" error. Note that this implementatino currently has a bug where errors occuring within thunks will yield the location at which the thunk was forced, not the location at which the error occured within the code. This will be fixed soon, but the commit is large enough as is.
