2022-09-07 r/4703 fix(tvix/eval): thread Display & PartialEq through to thunk valuesVincent Ambo2-1/+21
If a thunk is already evaluated, there are cases where due to the memoisation implementation something might observe a value wrapped in a thunk. In these cases, the implementation of `Display` and `PartialEq` must delegate to the underlying value. Note that there are a handful of other cases like these which we need to cover. It is a little tricky to write integration tests for these directly, especially as some of the open-upvalue optimisations coming down the pipe will reduce the number of observable thunks. One test that covers a part of this behaviour is currently disabled (needs some more machinery), but it's being brought back in the next commits.

These static strings show up a bunch when dealing with the internals of attribute sets, and having them available as static references is required. Due to the way const expressions are evaluated, taking a reference to the existing NixString::NAME / NixString::VALUE items does not work and the references themselves need to be const-evaluated.

The VM previously took care of repeatedly forcing a thunk until it reached an evaluated state. This logic is now encapsulated inside of the `Thunk::force` implementation. In addition, force no longer returns a reference to the value by default, leaving it up to callers to decide whether they want to borrow the value or not (a helper is provided for this).

2022-09-06 r/4659 fix(tvix/eval): instantiate *new* closures from blueprints each timeVincent Ambo2-5/+8
The previous closure refactoring introduced a bug in which the same closure object would get mutated constantly for each instance of a closure, which is incorrect behaviour. This commit instead introduces an explicit new Value variant for the internal "blueprint" that the compiler generates (essentially just the lambda) and uses this variant to construct the closure at runtime. If the blueprint ever leaks out to a user somehow that is a critical bug and tvix-eval will panic. As a ~treat~ test for this, the fibonacci function is being used as it is a self-recursive closure (i.e. different instantiations of the same "blueprint") getting called with different values and it's good to have it around.

2022-09-06 r/4658 fix(tvix/eval): correctly thread through dynamic upvaluesVincent Ambo1-1/+7
This puts together the puzzle pieces for threading dynamic upvalues (that is, upvalues resolved from the `with`-stack) all the way through. Reading the test case enclosed in this commit and walking through it is recommended to understand what problem is being tackled here. In short, because the compiler can not statically know *which* with-scope a dynamic argument is resolved from it needs to lay the groundwork for resolving from *all* possible scopes. There are multiple different approaches to doing this. The approach chosen in this commit is that if a dynamic upvalue is detected, the compiler will emit instructions to close over this dynamic value in *all* enclosing lambda contexts. It uses a new instruction for this that will leave around a sentinel value in case an identifier could not be resolved, and wire the location of this found value (or sentinel) up through the upvalues to the next level of nesting. In this tradeoff, tvix potentially closes over more upvalues than are needed (but in practice, how often do people create *really* deep `with`-stacks? and in *this* kind of code situation? maybe we should even warn for this!) but avoids keeping the entire attribute sets themselves around. Looking at the test case, each surrounding closure will close over *all* dynamic identifiers that are referenced later on visible to it, but only the last one for each identifier will actually end up being used. This also covers our bases for an additional edge-case this creates, in which an identifier potentially resolves to a dynamic upvalue *and* to a dynamic value within the function's own scope (again, would anyone really do this?) by introducing a resolution instruction for that particular case. There is likely some potential for cleaning up this code which is quite ugly in some parts, but as this implementation is now carefully calibrated to work I decided it is time to commit it and clean it up in subsequent commits.

2022-09-03 r/4625 feat(tvix/eval): compile creation of closure objectsVincent Ambo1-1/+11
Fully implements the instructions for compiling closure objects (without runtime handling yet). Closure (and thunk) objects are created at runtime by capturing all known upvalues. To represent this, the instructions for creating them need to have a variable number of arguments. Due to that, this commit introduces new variants in OpCode that are not actually operations, but data. If the VM is implemented correctly, the instruction pointer should never point at these. Due to this, the VM will panic if it sees a data operand during an execution run.

2022-09-03 r/4616 refactor(tvix/eval): avoid cloning in NixAttrs::update if possibleVincent Ambo1-20/+27
Refactors the update function to take the attribute sets by value instead. To facilitate this, we use an equivalent of the currently unstable `Rc::clone_or_unwrap` in the VM when encountering attribute sets, so that in cases where the only references to the attrs being updated are the ones on the stack those clones are avoided completely. This does make update() a little bit more tricky internally, as some optimised branches can directly return the moved value, and others need to destructure with ownership. For this reason there are now two different match statements handling the different ownership cases.

This way users will still eventually be able to add additional builtins, HOWEVER they will not be able to leak them into the global scope.
