2022-09-02 r/4588 feat(tvix/eval): introduce mechanism for defining builtinsVincent Ambo5-6/+48
Adds a new builtins module in which builtins can be constructed. The functions in this module should return a correctly structured value to be passed to the compiler's `globals`. This is wired up all the way to the compiler with an example `toString` builtin, available as a global. Note that this does not yet actually behave like the real toString, which has some differences from `Display`.

2022-09-02 r/4587 refactor(tvix/eval): handle scope poisoning & globals dynamicallyVincent Ambo1-61/+125
Previously, the tokens that could poison a scope (`true`, `false`, `null`) had individual fields in the scope to track whether or not they were poisoned. This commit sets up new machinery that instead tracks scope poisoning dynamically using a HashMap, and which makes it possible to introduce additional tokens to the top-level ("global") scope that are directly resolved by the compiler by passing a map of runtime values to be used. With this solution, the compiler now contains all machinery required for wiring up builtins resolution. The set of builtins to be exposed at runtime must, however, be constructed *outside* of the compiler and passed in. Everything is prepared for this, but it is not yet wired up (so the only existing builtins are the ones we already had before). Note that this technically opens up an optimisation potential when compiling selection operations, where the attribute set being selected from is `builtins`. The compiler could directly resolve the builtins and place the right values on the stack.

2022-09-02 r/4583 feat(tvix/eval): implement opcode for function calls in VMVincent Ambo3-8/+30
Nix functions always have a single argument and we do not yet make efforts to optimise this in Tvix for known multi-argument functions being directly applied. For this reason, the call instruction is fairly simple and just calls out to construct a new call frame. Note that the logic for terminating the run loop has moved to the top of the dispatch; this is because the loop run needs to be skipped if the call frame for the current lambda has just been dropped.

Since the latest published version of rnix-parser on crates.io, the crate has undergone major changes which are only available in the git repository at the moment. This commit updates the compiler to this newer version of rnix. Most notably, the entire AST provided by rnix is now wrapped in the AST type system. As a result of this traversal is much nicer in many places, especially for things like nested attribute selection. There are a handful of smaller features missing for full feature parity with the previous version, especially handling of path literals, but PRs for these already exist in rnix-parser.

This is supposed to help with resource wasting in situations when multiple dynamic steps depend on a failing derivation. Cost of failure currently is `C = T * D` where: - T -> time to compile the failing derivation - D -> amount of CI targets depending on a failing derivation Switching to `Fail Fast` limits it to just T (time of a single failure). Which helps a lot, especially while upgrading nixpkgs. Fast fail at this moment is in preview, so to enable it: - Enable `Fail Fast` feature at pipeline or organization level - Set `cancelOnBuildFailing` parameter to true for `mkPipeline` Change-Id: I4373a46633522d21e94cfa8bac35243b4eeb0b9c Reviewed-on: https://cl.tvl.fyi/c/depot/+/6243 Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>

2022-08-30 r/4544 fix(tvix/eval): `?` operator should use OpAttrsOrNotFoundVincent Ambo3-1/+5
Using `OpAttrSelect`, the ? operator will fail when encountering a nested value that is not an attribute set. This however breaks valid code, such as: { bs = 42; } ? bs.a.b The fix is simply to use the same operator used in the `or` statement, which leaves a sentinal on the stack if a field is not found or the value is not an attribute set.

2022-08-30 r/4543 fix(tvix/eval): `or` should handle non-attrset values, tooVincent Ambo3-5/+12
If a nested attrpath encounters a non-set value, the sentinel value denoting a lack of next values should be emitted. This mirrors the behaviour of Nix.

2022-08-30 r/4542 fix(tvix/eval): allow use of ? operator on non-set typesVincent Ambo4-4/+14
Nix allows this, but always returns false. Tvix needs to do the same. Change-Id: Ic9eec90834a0d0969eea5316d5c25032d3691d94 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6209 Reviewed-by: grfn <grfn@gws.fyi> Tested-by: BuildkiteCI
