2024-04-30 r/8042 refactor(nix-compat/wire): drop primitive functionsedef1-3/+5
These may as well be inlined, and hardly need tests, since they just alias AsyncReadExt::read_u64_le / AsyncWriteExt::write_u64_le. Boolean reading is worth making explicit, since callers may differ on how they want to handle values other than 0 and 1. Boolean writing simplifies to `.write_u64_le(x as u64)`, which is also fine to inline.

2024-04-13 r/7897 refactor(tvix/nix-compat): move worker_protocol into nix_daemon modFlorian Klink1-4/+2
This doesn't have much to do with the plain "wire" format, it's merely one user of it. Also, use the more "public" `wire::` API to read/write bytes, strings, bools and u64s.

2024-04-13 r/7896 refactor(tvix/nix-compat): reorganize wire and bytesFlorian Klink1-3/+3
Move everything bytes-related into its own module, and re-export both bytes and primitive in a flat space from wire/mod.rs. Expose this if a `wire` feature flag is set. We only have `async` stuff in here.

2024-04-08 r/7876 refactor(tvix/nix-compat): move handshake function to nix-compatPicnoir1-119/+19
Moving out the handshake route out of tvix-daemon to nix-compat. We're bumping the protocol to version 37. It does not change anything for us. Version 37 introduced a change in the build result serialization. We do not implement that for now. Tested tvix-daemon against Nix via the integration test to make sure we did not break anything in the process. Taking advantage of this refactor to remove the unused anyhow dependency in tvix-daemon.

2024-04-08 r/7875 refactor(tvix/nix-compat/wire): express magics as u64Florian Klink1-13/+10
This allows using read_u64, write_u64, which is a bit easier to juggle with. Also, update names to align with the nix codebase, which makes it easier to spot both the constant name as well as the value. Leave the ASCII interpretation as a comment afterwards.

2024-04-07 r/7868 feat(users/picnoir/tvix-daemon): implement set_options operationPicnoir1-9/+52
The protocol is more stateful than I initially thought. We need to keep track to a bunch of things, including but not limited to: the client settings, the client version. I moved things around a bit to keep this state along with the client socket.

2024-04-03 r/7845 feat(users/picnoir/tvix-daemon): parse up to the operationPicnoir1-11/+32
Using all the primitives recently implemented to nix-compat to reach the point where the Nix client start to send us operation requests. Using a small integration test script (or the VM test, but let's face it, it's too slow to be useful), we manage to reach the point where we're able to read a store operation: 2024-03-21T18:53:27.624876Z INFO tvix_daemon: Incoming connection addr=unix 2024-03-21T18:53:27.625312Z INFO worker:perform_init_handshake: tvix_daemon: Trust sent conn=Connection(unix) conn=Connection(unix) 2024-03-21T18:53:27.625406Z INFO worker: tvix_daemon: Client hanshake succeeded conn=Connection(unix) 2024-03-21T18:53:27.625488Z INFO worker: tvix_daemon: Operation received op=SetOptions conn=Connection(unix) We had to take some shortcuts wrt. stderr/log management. The CPP Nix codebase is a bit confusing in that area. I'll need to spend more time reading this to fully understand what's happening there. For now, sending the STDERR_LAST command to the client does the trick.

2024-03-19 r/7742 feat(users/picnoir/tvix-daemon): introduce tvix-daemonPicnoir1-0/+89
This daemon is a re-implementation of the Nix daemon except it uses tvix-store as a remote store. For now, it's very barebones, this is just a quick and dirty setup to get started with the project. We bind to the unix socket provided by systemd, wait for cpp Nix to send the magic hello bytes, respond with the magic hello bytes and call it a day. Storing this under my username for now, the project is mostly irrelevant as it is. We'll move it to Tvix if it gets complete and relevant at some point.
