2023-01-25 r/5754 feat(tvix/eval): implement builtins.fromTOMLFlorian Klink7-3/+220
This allows parsing TOML from Tvix. We can enable the eval-okay-fromTOML testcase from nix_tests. It uses the `toml` crate, and the serde integration it brings with it.

2023-01-25 r/5753 feat(tvix/eval): use lexical-core to format floatFlorian Klink6-4/+411
Apparently our naive implementation of float formatting, which simply used {:.5}, and trimmed trailing "0" strings not sufficient. It wrongly trimmed numbers with zeroes but no decimal point, like `10000` got trimmed to `1`. Nix uses `std::to_string` on the double, which according to https://en.cppreference.com/w/cpp/string/basic_string/to_string is equivalent to `std::sprintf(buf, "%f", value)`. https://en.cppreference.com/w/cpp/io/c/fprintf mentions this is treated like this: > Precision specifies the exact number of digits to appear after > the decimal point character. The default precision is 6. In the > alternative implementation decimal point character is written even if > no digits follow it. For infinity and not-a-number conversion style > see notes. This doesn't seem to be the case though, and Nix uses scientific notation in some cases. There's a whole bunch of strategies to determine which is a more compact notation, and which notation should be used for a given number. https://github.com/rust-lang/rust/issues/24556 provides some pointers into various rabbit holes for those interested. This gist seems to be that currently a different formatting is not exposed in rust directly, at least not for public consumption. There is the [lexical-core](https://github.com/Alexhuszagh/rust-lexical) crate though, which provides a way to format floats with various strategies and formats. Change our implementation of `TotalDisplay` for the `Value::Float` case to use that. We still need to do some post-processing, because Nix always adds the sign in scientific notation (and there's no way to configure lexical-core to do that), and lexical-core in some cases keeps the trailing zeros. Even with all that in place, there as a difference in `eval-okay- fromjson.nix` (from tvix-tests), which I couldn't get to work. I updated the fixture to a less problematic number. With this, the testsuite passes again, and does for the upcoming CL introducing builtins.fromTOML, and enabling the nix testsuite bits for it, too.

Two main reasons: 1. Traversing the structure to do this optimisation is actually *slower* than not optimising it. 2. There are literally hundreds of thousands of incidences of this in nixpkgs, and with some of the weird code there some of these (functionally) useless parens are actually required for readability reasons.

All of these occurences are actually sha256 digests of some fingerprint - which means there's not a lot of need to do the hashing outside. Instead of passing in a digest, keep the sha256 hasher in the function, and pass in a fingerprint. This makes it much easier to construct fingerprints using format!() in all consumers, because we need don't need to juggle with the hasher anymore.

2023-01-21 r/5721 refactor(tvix/eval): administer antidote for poisonAdam Joseph8-135/+49
The codebase contains a lot of complexity and odd roundabout handling for shadowing globals. I'm pretty sure none of this is necessary, and all of it disappears if you simply make the globals part of the ordinary identifier resolution chain, with their own scope up above the root scope. Then the ordinary shadowing routines do the right thing, and no special cases or new terminology are required. This commit does that. Note by tazjin: This commit was originally abandoned when Adam decided not to take away reviewer bandwidth for this at the time (eval was still in a much earlier stage). As we've recently done some significant refactoring of globals initialisation this came up again, and it seems we can easily cover the use-cases of the poison tracking in other ways now, so I've rebased, updated and resurrected the CL.

2023-01-17 r/5669 feat(tvix/cli): add known_paths moduleVincent Ambo3-5/+143
This module implements types used to track the set of known paths in the context of an evaluation. These are used to determine the build references of a derivation.

2023-01-16 r/5666 chore(tvix/derivation): drop TODOs related to stripping outputsFlorian Klink1-2/+0
Different to the go-nix implementation, we don't have a custom "writing mode" where output paths are omitted from output, but we simply run the serialization with these fields unpopulated (during construction). This means, there's no need for a custom writing mode that strips outputs, so we can drop the comments.

2023-01-16 r/5665 feat(tvix/eval): add error variant for threading through errorsVincent Ambo1-2/+17
This variant is required for external builtins (which in our case includes `derivation`) to thread through reasonable error messages. This has some potential for improvement, but it's an improvement over the status quo of panicking in the external builtins when no appropriate error is available.

2023-01-16 r/5662 docs(tvix): add reconstructed changelog for the Nix languagesterni1-0/+60
This was put together by digging through the C++ Nix git history as described in the second paragraph. Note that this is only based on changes given when the language version was actually increased. There is no guarantee that there have been no other changes inbetween that would have warranted an increase as well.
