Release Notes
Fixed
- M5 — a completely failed speed test now reports failure (exit 2) instead of a misleading "too slow" warning. When every speed-test provider errors out (or returns zero throughput),
diagnostics/speed.rs previously fell through determine_speed_status to the slow-link branch, producing a 0.00 Mbps down / up aggregate, a "Download too slow for most activities" warning, and exit 1. determine_speed_status now first checks whether any provider succeeded (no error) and reported positive throughput in either direction; if not, it returns the new SpeedStatus::Failed, which check() maps to a Fail-status diagnostic with an honest standalone summary ("Speed test failed — no provider returned a result", with no fabricated 0.00 Mbps line). A genuinely slow-but-working link (e.g. 0.3 Mbps from a successful provider) is unaffected — the positive-throughput guard keeps it Poor → Warn.
- L1 — the NDT7 speed test's per-direction safety timeout now actually fires. The NDT7 download loop (
speedtest/ndt7.rs) re-armed a fresh 30s tokio::time::sleep(SINGLE_TEST_TIMEOUT) on every tokio::select! iteration, so the safety cap could never elapse and was dead code. It is now a single pinned absolute deadline (Instant::from_std(start + SINGLE_TEST_TIMEOUT)) computed once before the loop and driven with sleep_until, mirroring the existing per-session deadline arm. The upload loop, which previously had no safety cap at all, gets a symmetric pinned cap so a wedged write.send is now bounded.
Changed (be aware if you script against the tool)
- The exit code for a fully-failed speed test (every provider errored / zero throughput) is now 2 (Fail) instead of 1 (Warn), and the
Speed diagnostic's summary is Speed test failed — no provider returned a result rather than a 0.00 Mbps … too slow line. A slow-but-working connection is unchanged (still Warn / exit 1).
Behind the scenes
- L5 — system-info lookups in the core diagnostics no longer briefly block the async runtime. The synchronous, potentially-blocking
sysinfo::Networks::new_with_refreshed_list() and default_net::get_default_gateway() calls in diagnostics/gateway.rs, diagnostics/public_ip.rs, diagnostics/interfaces.rs, and diagnostics/shared_cache.rs are now wrapped in tokio::task::spawn_blocking, returning owned Send data with a JoinError fallback to the pre-existing empty/None result (never an unwrap panic). interfaces.rs extracts owned per-interface fields (name, MAC bytes, IPs, rx/tx) inside the blocking closure and keeps its async, timeout-wrapped get_wifi_summary() call outside it; the is_up semantics (has an IP && rx > 0) are byte-for-byte preserved. Mirrors the existing spawn_blocking pattern in actions/fix/adapters.rs and diagnostics/vpn.rs.
Known limitations
- L2 (deferred) — localized (non-English) Windows. On non-English Windows display languages, some deep-diagnostic modules that parse localized
netsh / ipconfig / netstat output may return empty or partial results, because they match English labels and decode console output as UTF-8. This is tracked for a future locale-invariant parsing pass and is not addressed in this release.
