2024-04-29 r/8030 refactor(nix-compat/wire/bytes): fold TrailerReader into BytesReaderedef2-91/+41
The TrailerReader has no purpose separate from BytesReader, and the code gets a fair bit simpler this way. EOF handling is simplified, since we just rely on the implicit behaviour of the existing case.

The poisoning API is now always available, whether debug_assertions is enabled or not. When debug assertions are not enabled, it is equivalent to a unit struct, and is always considered ready and unpoisoned.

2024-04-26 r/8016 feat(nix-compat/wire/bytes/reader): split out reading the trailer blockedef1-56/+134
We separate ingesting the trailer block into a Future of its own, parametrised on the specifics of the trailer pattern. This is intended to be used for future work on an async NAR reader, which needs to read a terminating parenthesis as well as the regular padding. Thanks to @griff for suggesting separating the ingestion into its own Future.

We now *never* return the final bytes until we've read the padding in full, so read_exact is safe to use. This is implemented by TrailerReader, which splits the phases of reading (and validating) the final 8-byte block, and providing the contained payload bytes to the caller.

This isn't used anywhere so far, and if someone really wants to, they can simply make the range open-ended. Change-Id: Iae9bcaa1f7ea032dd3ee76c8c142a38b6b72894d Reviewed-on: https://cl.tvl.fyi/c/depot/+/11373 Reviewed-by: picnoir picnoir <picnoir@alternativebit.fr> Tested-by: BuildkiteCI
2024-04-07 r/7869 fix(nix-compat/store_path): fix Deserialize with borrowFlorian Klink1-3/+37
We were wrongly using `'de` as a lifetime for both `Deserializer` and `StorePathRef`. This prevented Deserializing into a struct containing `StorePathRef`. See https://serde.rs/lifetimes.html#the-deserializede-lifetime, the last part of the paragraph: The 'de lifetime should not appear in the type to which the Deserialize impl applies. - // Do not do this. Sooner or later you will be sad. - impl<'de> Deserialize<'de> for Q<'de> { + // Do this instead. + impl<'de: 'a, 'a> Deserialize<'de> for Q<'a> { This fixes it, and adds a test, deserializing into a `Container` struct. It also fixes the existing test cases, deserialize_ref was actually deserialize_owned, and deserialize_owned didn't exist yet - but they alone are not enough to provoke the lifetime issues.

2024-04-07 r/7867 feat(tvix/nix-compat): read client setting from wirePicnoir2-3/+225
Add the primitives necessary to read the client settings from the Nix daemon wire protocol. Introducing the read_string primitive. This trivial primitive parses a read_bytes call, check the bytes are valid utf-8 bytes and wraps the result in a String.

2024-04-06 r/7857 feat(tvix/nix-compat/wire): introduce BytesWriterFlorian Klink3-1/+524
This deals with writing byte packets of larger sizes to an underlying AsyncWrite. Its constructor receives the expected size. It also deals with writing padding if flush/shutdown is called after writing all the payload.
