Vincent Ambo b9646ab40c feat(tvix/eval): add builtins to builtins
This is a somewhat terrifying hack that enables us to support
`builtins.builtins`, by running a "fake compilation" inside of a
suspended native thunk that can resolve the weak pointer to the
globals.

With this implementation, the thunk at `builtins.builtins` actually
resolves to the "real" `builtins` (verified with a new test).

This is kind of ugly, and it's something users shouldn't use, but
bubbling a warning out of this is difficult at the moment due to a
little bit of trickery with how the spans in suspended native thunks
work (they don't) (see b/237, b/238)

Tvix

For more information about Tvix, contact one of the project owners. We are interested in people who would like to help us review designs, brainstorm and describe requirements that we may not yet have considered.

Rust projects

Some parts of Tvix are written in Rust. To simplify the dependency management on the Nix side of these builds, we use crate2nix in a single Rust workspace in //tvix to maintain the Nix build configuration.

When making changes to Cargo dependency configuration in any of the Rust projects under //tvix, be sure to run mg run //tvix:crate2nixGenerate -- in //tvix itself and commit the changes to the generated Cargo.nix file.

License structure

All code implemented for Tvix is licensed under the GPL-3.0, with the exception of the protocol buffer definitions used for communication between services which are available under a more permissive license (MIT).

The idea behind this structure is that any direct usage of our code (e.g. linking to it, embedding the evaluator, etc.) will fall under the terms of the GPL3, but users are free to implement their own components speaking these protocols under the terms of the MIT license.
