Three tests for the previous two commits, next to the existing abandon tests in multipath.rs: - abandoned_path_in_flight_retransmits_after_pto_delay: stream data lost on path 0, path 0 abandoned, all server-to-client traffic dropped from then on so the PathDrained cleanup never arms. Only the declare-in-flight-lost timer can free the data; asserts it has not fired below the 2*PTO lower bound (probed via handle_timeout without advancing the clock) and that the data arrives over path 1 after it. Fails on main (data stranded forever) and on the immediate variant (retransmit before the deadline). - abandoned_path_acked_in_flight_not_retransmitted: the flight's delayed acknowledgment is in the client's inbound queue when the path is abandoned; processing it during the window leaves nothing to declare lost, so no stream frame is sent twice. Fails on the immediate variant - this is the reason the declare-lost is deferred. - abandoned_path_partially_acked_retransmits_only_rest: two flights in the air at abandon time, the first acknowledged mid-window and the second lost; exactly one stream frame is retransmitted. Also covers the deadline surviving mid-window ACK processing (set_loss_detection_timer leaving abandoned paths alone). Verified against both predecessors: on main (5cf07f483) the first test fails, on the immediate declare-lost variant (630db780d) all three fail; on this branch 390/390 pass.
noq
General purpose implementation of the QUIC transport
protocol in pure
Rust. Noq is built as an async-friendly API in the noq crate on top
of a sans-io protocol library in noq-proto.
Noq started out as a fork of the excellent Quinn project. The main focus of development has been towards adding support for more QUIC (draft) extensions:
Features
- Easy to use futures-based async API.
- Client and server server functionality.
- 0-RTT and 0.5-RTT data support.
- Ordered and unordered stream reads.
- Custom and zero-length connection identifiers.
- Fully pluggable crypto API with a Rustls implementation using ring or aws-lc-rs provided by default for convenience.
- Broad platform support, including Linux, Windows, macOS, android, iOS and wasm.
Standards
The noq library aims to be correct implementation of various QUIC standards:
- Supports the core QUIC specifications:
- The standardised QUIC extensions:
- Draft extensions:
- qlog: Structured Logging for Network Protocols.
- QUIC Multipath.
- With experimental qlog support.
- QUIC Address Discovery (QAD).
- Using QUIC to traverse NATs (QNT).
Getting started
Examples at https://github.com/n0-computer/noq/blob/main/noq/examples
$ cargo run --example server ./
$ cargo run --example client https://localhost:4433/Cargo.toml
This launches an HTTP 0.9 server over the QUIC transport on the loopback address serving the current working directory, with the client fetching ./Cargo.toml. By default, the server generates a self-signed certificate and stores it to disk, where the client will automatically find and trust it.
