migrate to sing-box v1.13.19 typed-options - #612
Conversation
Bump sing-box to v1.13.19-lantern and lantern-box, and replace the map[string]any / libbox JSON handling with typed option.Options decoded through box.Context. - peer: build the box with sbox.New instead of libbox.NewServiceWithContext; validate abuse rules against typed option.Options; extract newPeerBoxContext and cover it (log factory, registries, caller cancellation) with tests. - peer: create the VPN-bypass route block when the config lacks one so auto_detect_interface is always set; OR-accumulate the static reject canaries; cancel runCtx on the verify-failure path. - servers: hold the registry context on Manager and read it through a nil-safe accessor so a directly constructed Manager still (un)marshals. - vpn: derive the box context with box.Context; drop the libbox.Setup base/temp paths; align the ad-block ruleset test with the JSON round-trip's default reject method.
RunOfflineURLTests rooted its context at context.Background(), so the only way to cancel an in-flight test was VPNClient.Connect. On macOS and mobile the tunnel lives in the extension process while the UI process runs its own LocalBackend; closing that backend on tunnel-up did not reach the test, leaving probe dials in flight. Once the extension's TUN came up they were captured by it and re-proxied, corrupting server selection. Thread a context through RunOfflineURLTests and pass r.ctx so closing the backend cancels the tests. Also defer the cancel so the context is released on normal completion instead of leaking.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The typed-options migration and backend-cancellation changes are mergeable with owner awareness, but the default build commands currently enable different feature sets and one validation test fixture should be corrected so it exercises the intended rule checks.

Pull request overview
This PR migrates Radiance’s sing-box integration to the v1.13.19 typed-options flow (decoding option.Options via box.Context), and fixes an operational issue where offline URL tests could continue dialing after the backend was closed (leading to server-selection corruption).
Changes:
- Switches VPN and peer box setup from JSON/map-based option handling to typed
option.Options, constructing boxes withsbox.New. - Threads backend lifetime context into
RunOfflineURLTestsand ensures cancellation/cleanup on backend close. - Updates sing-box option-building and (un)marshalling paths to use
box.Contextand round-trip options through JSON to populate defaults.

vpn/tunnel.go:293
- This start path still uses "libbox" in the trace span name and error strings after switching from libbox.BoxService to *sbox.Box. Updating these messages will keep traces and logs accurate.
if err := traceSpan(ctx, "libbox.BoxService.Start", func() error {
return t.boxInstance.Start()
}); err != nil {
slog.Error("Failed to start libbox service", "error", err)
return fmt.Errorf("starting libbox service: %w", err)

Summary
Migrates radiance to sing-box v1.13.19-lantern and lantern-box, replacing the
map[string]any/ libbox JSON handling with typedoption.Optionsdecodedthrough

Changes
to v1.13.19-lantern and switches to typed
option.Optionsdecoded throughbox.Context:peer: builds the box withsbox.Newinstead oflibbox.NewServiceWithContext; validates abuse rules against typedoption.Options; extracts and testsnewPeerBoxContext(log factory,registries, caller cancellation).
servers: holds the registry context onManager, read through anil-safe accessor so a directly constructed
