2023-08-20 r/6494 feat(tvix/nix-compat): don't swallow hash validation errorsRyan Lahfa3-58/+208
Previously, Output deserialization would silence validation errors and provide `None` for `hash_with_mode` as soon as a validation error would happen inside of the `NixHashWithMode` deserialization, e.g. invalid hash length would not provide an validation error but a silent `None` value. This is problematic, we workaround a serde limitation here by writing our own Deserializer. As you can see, we write some boilerplate code unfortunately, as, for example: - `#[serde(fail_if_unparsed_as="Option::is_none")]` is not a thing, otherwise, we could have been able to just bubble up errors in case of "not fully parsed" (and not missing) values. - `From<&serde_json::Value> for serde::de::Unexpected` is not a thing, otherwise, we could just map invalid type errors and reuse the existing types instead of doing extremely bizarre things with `serde::de::Unexpected::Other`, note: this is a not problem for expected, we know what we expect, we don't know what we received in practice. I decided to write a `NixHashWithMode::from_map` which will eat a map deserialized via `serde_json`, so our serde magic is not totally "data model" agnostic. I wanted to go for data model agnosticity and enable maximal performance, e.g. building the structure as the map values are streamed in the Visitor, this is needlessly painful because `Output` and `NixHashWithMode` are in different files and this really makes sense only if we write the full implementation in one file, indeed, otherwise, you end up duplicating the work or having strange coupling. So, for now, we will allocate a full map of the fields inside the `Output`, i.e. if any "unknown field" is in that map, we will deserialize it for no reason. Doing it properly, as I repeat it in the code and to flokli at C3Camp 2023, requires to patch serde upstream IMHO.

Some paths might use names that are not valid UTF-8. We should be able to represent them. We don't actually need to touch the PathInfo structures, as they need to represent StorePaths, which come with their own harder restrictions, which can't encode non-UTF8 data. While this doesn't change any of the wire format of the gRPC messages, it does however change the interface of tvix_eval::EvalIO - its read_dir() method does now return a list of Vec<u8>, rather than SmolStr. Maybe this should be OsString instead?

The primary constructor for this is now from_bytes, from_string is simply calling .as_bytes() on the string, passing it along. The InvalidName error now contains a Vec<u8>, to encode the invalid name (which might not be a string anymore). from_absolute_path now accepts a &[u8] (even though we might want to make this a OSString of some sort). StorePath::validate_name has been degraded to a pub(crate) function. It's still used in src/derivation, even though it probably shouldn't at all - that cleanup is left for cl/8412 though.

2023-07-21 r/6432 feat(tvix/nix-compat): fold NameError into ErrorFlorian Klink4-39/+27
This being a nested error makes things more complicated than necessary. Also, this caused BuildStorePathError to only hold NameError, so refactor these utility functions to either return Error, or BuildStorePathError.

2023-07-11 r/6405 docs(tvix): document when pointer equality is preserved in C++ Nixsterni5-6/+169
This explicitly documents behavior of C++ Nix that goes against the intuition you'd gather from this document: that e.g. a simple select from an attribute set causes a value to no longer be pointer equal to its former self. The point of documenting this is that we can show in a to be written section on the use of pointer equality in nixpkgs that pointer equality is only needed in a limited sense for evaluating it (C++ Nix's exterior pointer equality). Tvix's pointer equality is far more powerful since value identity preserving operations also preserve pointer equality, generally speaking (this is because we implement interior pointer equality in my made up terminology). This should eventually also be documented.

2023-07-11 r/6404 fix(tvix/eval): use byte, not codepoint index for slicing in escapesterni3-1/+12
This fixes a subtle issue which would occasionally lead to a crash (e.g. when evaluating (pkgs.systemd.outPath with --trace-runtime): With each character in the string that has a multi byte representation in UTF-8, the actual byte position and what tvix thought it was would get out of sync. This could either lead to * Tvix swallowing characters or jumbling characters if multi byte characters would cause the tracked index to become out of sync with the byte position before the first character to be escaped, or * Tvix crashing if (in the same situation) the out of sync index would be within a UTF-8 byte sequence. Luckily, std's `char_indices()` iterator implements exactly what `nix_escape_char()`'s original author had in mind with `.chars().enumerate()`. Using `i + 1` for continuing is safe, since all characters that need (in fact, can) to be escaped in Nix are represented as a single byte in UTF-8.
