2024-01-03 r/7338 feat(tvix/glue): contextful derivationRyan Lahfa1-123/+8
We calculate the input context by performing the union of context over all input of the derivation. Then, we just pass the rest of it to the remaining machinery. Finally, we re-emit an `outPath` and a `drvPath` containing the expected contexts.

2023-12-12 r/7160 chore(tvix/glue): allow unused_variablesFlorian Klink1-0/+1
cl/9364 did introduce a warning here, which is visible when building in release mode - or invoking `cargo bench` in tvix-glue.

2023-12-10 r/7142 fix(tvix/cli): panic on root cause of the fetchurl(non-boot) bugAdam Joseph1-1/+27
Currently we produce wrong drvPaths for a large number of packages that use fetchurl (but not fetchurlBoot, which is what stdenv uses). A simple reproducer is `pkgs.perl538`. I debugged this down to the root cause, which is the fact that tvix doesn't realize that the mapping from FOD-paths to outputHash is *NOT* a 1:1 mapping. It is a many-to-one mapping. You can have lots of different FODs with the same outputHash or even the same outPath. For example, perl538.src and perldevel.src use the same source tarball but a different `version`. Anyways, I have found the root cause but have run out of time for a while, so I've added a panic!() to in the spot where we have a logic bug in order to call it out.

2023-11-04 r/6936 refactor(tvix): move tvix glue code into glue crateFlorian Klink1-0/+186
There's various bits and pieces in tvix-cli that use both the store and evaluator, as well as nix-compat. For example, builtins.derivation, as well as the reference scanning implementation. This "glue code" currently isn't accessible from anywhere else, but it'd be very useful if it were. Move it out into a `glue` crate, and make `tvix-cli` a consumer of it. All the KnownPaths setup and passing around, as well as NIX_PATH handling is also something that should probably be moved into the glue crate as well, but that's something left for a future CL.
