Rewrite of kouko in Rust, for better performance!
Kiryuu powers http://tracker.mywaifu.best:6969/announce
Many thanks to horsie and anon from Discord, both of whom were extremely helpful in helping me get more familiar with rust, and for offering their heads as I bounced ideas across them.
The current release can be considered stable, but is not intended for use by others - it is not very customizable yet. That said, feel free to hack around with it if you like!
Best to build in release mode and target your CPU natively for better performance.
$ RUSTFLAGS="-C target-cpu=native" cargo build --release
Building a static binary is possible with the musl target, with something like:
$ cargo build --target=x86_64-unknown-linux-musl --release
Make sure you set a high ulimit for open files! By default some VPS might set this to 1024, and then kiryuu won't be able to handle high traffic.
If you've already started kiryuu, you can identify its PID and then set it via:
$ prlimit --pid PID_HERE --nofile=16384:16384
There are integration tests via Gauge that run in CI. The tests are located at https://github.com/ckcr4lyf/kiryuu-gauge
To run them locally, you could use:
$ docker run -e KIRYUU_HOST=http://172.17.0.1:6969 -e REDIS_HOST=redis://172.17.0.1:6379 ghcr.io/ckcr4lyf/kiryuu-gauge:master
(Make sure you've kiryuu running locally and redis as well!)
Or you can just send an example cURL
curl "localhost:6969/announce?info_hash=AAAAAAAAAAAAAAAAAAAA&port=1337&left=0"
To build with tracing, enable the tracing feature:
$ RUSTFLAGS="-C target-cpu=native" cargo build --release --features tracing
Kiryuu currently supports exporting traces via an OTLP endpoint. E.g. you can run a collector via The OTEL quick start.
Or use Grafana Cloud w/ Grafana Alloy.
