2023-01-31 r/5794 feat(tvix/store): add write_nar functionFlorian Klink6-22/+351
This adds a function that consumes a [proto::node::Node] pointing to the root of a (store) path, and writes the contents in NAR serialization to the passed [std::io::Write]. We need this in various places: - tvix-store's calculate_nar() RPC method needs to render a NAR stream to get the nar hash, which is necessary to give things imported in the store a "NAR-based" store path. - communication with (remote) Nix (via daemon protocol) needs a NAR representation. - Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a NAR representation.

2023-01-27 r/5772 fix(tvix/cli): handle SRI hashes in outputHashFlorian Klink5-38/+573
Instead of being called with `md5`, `sha1`, `sha256` or `sha512`, `fetchurl.nix` (from corepkgs / `<nix`) can also be called with a `hash` attribute, being an SRI hash. In that case, `builtin.derivation` is called with `outputHashAlgo` being an empty string, and `outputHash` being an SRI hash string. In other cases, an SRI hash is passed as outputHash, but outputHashAlgo is set too. Nix does modify these values in (single, fixed) output specification it serializes to ATerm, but keeps it unharmed in `env`. Move this into a construct_output_hash helper function, that can be tested better in isolation.

We're doing it this way to ensure that our thunking logic is correct.

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.

2023-01-23 r/5747 chore(tvix/eval): delete "useless parenthesis" warning/optimisationVincent Ambo2-30/+0
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.

2023-01-23 r/5746 fix(tvix/eval): force functors before applying themVincent Ambo3-0/+12
call_value in the VM expects the callable to be forced when calling it, which was not the case for functors. Change-Id: Id55a2fe32a9573be42aef8669e268df519a989cd Reviewed-on: https://cl.tvl.fyi/c/depot/+/7909 Tested-by: BuildkiteCI Reviewed-by: sterni <sternenseemann@systemli.org>

2023-01-23 r/5739 refactor(tvix/derivation): remove DOT_FILE_EXT constFlorian Klink3-13/+3
This is used in few enough places to just inline it. It felt a bit alien in the ATerm construction aswell. write.rs now pleasantly only includes tokens that occur in the ATerm representation.

2023-01-23 r/5738 refactor(tvix/derivation): pass fingerprint to build_store_pathFlorian Klink2-66/+51
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.

2023-01-23 r/5737 feat(tvix/derivation): add `path_with_references`Vincent Ambo3-1/+63
This allows the calculation of a store path for a plain string that potentially contains references. These paths are used for `builtins.toFile` (and potentially other features of C++ Nix).
