From 56f559128364b500d35fc28360ca40fb70c3ac59 Mon Sep 17 00:00:00 2001 From: iHsin Date: Fri, 5 Jun 2026 21:13:23 +0800 Subject: [PATCH 1/3] =?UTF-8?q?quality:=20PR5=20=E2=80=94=20perf,=20qualit?= =?UTF-8?q?y,=20and=20dead-code=20cleanups?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Last wave of the full-project review. Mostly small, low-risk janitorial changes; the perf ones (install_default OnceLock, the ACL format-* zero-alloc Display, the wind-naive per-packet allocations) actually move on a hot path. Perf / correctness * `TuicOutbound::new` now installs the rustls default crypto provider exactly once per process via a `static OnceLock<()>`. The previous `let _ = install_default()` ran on every new outbound and silently swallowed the post-first `Err`. * `tuic-server::acl::format_protocol` returns `&'static str` ("tcp/"/"udp/"/""), and `format_optional_parts` now returns an inline `Display`-impl wrapper instead of a `format!`-built `String`. Both were on the rule-pretty-print hot path. * `wind-core::dispatcher::rule_target_to_action` already preserved the outbound name's case in PR4; this PR keeps that and adds tests alongside the other PR4-A changes. Quality / safety * `wind-tuic` quinn `acceptor_loop` no longer logs `ApplicationClosed` / `LocallyClosed` / `TimedOut` as ERROR — those are benign connection-lifecycle events. Demoted to DEBUG so red- herring ERRORs disappear from logs. * `wind` `init_log` filter now lists every wind workspace crate (`wind_acme`, `wind_base`, `wind_dns`, `wind_naive` were missing and silently fell through to the default INFO). * `WIND_OVERRIVE_VERSION` typo: the canonical name is now `WIND_OVERRIDE_VERSION`; the old (misspelled) name still works as a fallback for one release so existing CI doesn't break. * `tuic-client::wind_adapter`: when `relay.sni` is unset AND `relay.server.0` is an IP literal, emit a loud warning and use a non-IP placeholder instead of stuffing the IP into the TLS SNI extension (rustls rejects that anyway). * `wind/main.rs` clap parsing: actual errors now go to stderr with a non-zero exit code via `Error::exit()` instead of `println!` + exit 0. Version/help still go to stdout cleanly. * `wind-socks::inbound::SocksInbound::new` is no longer `async` — it never awaited anything. Two callers updated. * `wind-socks::ext`: replaced the misleading `warn!("unreachable")` on the happy path with a clean-shutdown `debug!`. * `wind-tuic::proto::cmd`: dropped the typo'd rebind `assoc_id: assos_id` in the Packet/Dissociate encode arms. Dead code removed (~150 lines net) * `wind-tuic::quiche::tls::TlsConfig` (defined, never used). * `wind-core::outbound::compat::TokioTcpCompat` (defined, never used). * `wind-core::interface::StackPrefer` (duplicated — `utils::StackPrefer` was shadowing it via `pub use`; the two had different serde aliases). * `wind-tuic::quiche::utils::QuicheError` + `QuicheResult` (every variant unconstructed; whole quiche subsystem is still a placeholder). * `tuic-client::forward::UDP_SESSIONS` + `ForwardUdpSession` (the registry was being written but never read). * `tuic-server::tls` test helper: stray `key_pair.serialize_der()`. * `tuic-server::config`: a tautological `assert!(env_state.opt.is_none() || env_state.opt.is_some())`. Tests / fmt * +2 tuic-server unit tests for `format_protocol` / `format_optional_parts`. * cargo +nightly fmt --all clean. * Full workspace `cargo test --workspace --all-targets` green (~265 tests across 18 binaries, 0 failures).

That justification was thin: * `OVERRIVE` is a misspelling, not a deliberate name — there's no plausible reason anyone set it intentionally. * Even if some CI does use it, the fix is a one-line sed in the CI config. * Keeping the fallback normalizes the misspelling in source and forces every future reader to wonder which name wins. * The 3-arm `match` lives in the binary permanently. Just delete it. `WIND_OVERRIDE_VERSION` is now the only build-time override.
