From ba6c2ac6baa53db0e8bf2d571adafddacf533782 Mon Sep 17 00:00:00 2001 From: efiten Date: Thu, 21 May 2026 20:39:43 +0200 Subject: [PATCH] feat: repeater liveness indicator with relay stats (#662) (#755) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - **Backend**: adds `relayTimes` in-memory index (sorted unix-millis per repeater pubkey), maintained in lockstep with `byPathHop`. Populated at startup from all packet observations (not just best), updated on ingest/evict/backfill. Exposes `relay_count_1h`, `relay_count_24h`, `last_relayed` in both `/api/nodes` (for repeaters) and `/api/nodes/{pubkey}/health`. - **Frontend**: `getNodeStatus` extended to three-state (`relaying` / `active` / `stale`) for repeaters based on relay_count_24h. `getStatusInfo` is the single source of truth for status label, explanation, and relay stats. Detail pane shows relay counts and last relayed time. Nodes list gets a status emoji column with hover tooltip showing relay info. - **Correctness fixes**: relay index scans all observations per packet (not just best); backfill now updates relay index after resolving paths; pubkeys lowercased consistently throughout index. ## Changes ### `cmd/server/store.go` - `relayTimes map[string][]int64` field added to `PacketStore` - `addTxToRelayTimeIndex` / `removeFromRelayTimeIndex`: scan all observations, idempotent sorted insert, lowercase keys - `relayMetrics(times, nowMs)`: returns `(count1h, count24h, lastRelayed)` - `buildPathHopIndex`: populates `relayTimes` at startup - `pollAndMerge`: updates relay index on ingest and eviction; new `else` branch for path-unchanged observations - `addTxToPathHopIndex` / `removeTxFromPathHopIndex`: lowercase resolved pubkeys (fixes casing mismatch with lookup) ### `cmd/server/routes.go` - `GetBulkHealth` / `GetNodeHealth`: include relay stats for repeater nodes - `handleNodes`: enriches repeater nodes with relay stats from `relayTimes` so list view has same data as detail pane ### `cmd/server/neighbor_persist.go` - `backfillResolvedPathsAsync`: calls `addTxToRelayTimeIndex` after `pickBestObservation` to capture newly resolved pubkeys ### `public/roles.js` - `getNodeStatus(role, lastSeenMs, relayCount24h)`: three-state logic for repeaters - `getStatusInfo(n)`: single source of truth returning status, label, explanation, relay counts, last relayed ### `public/nodes.js` - Detail pane: `n.stats` populated from health endpoint before `getStatusInfo` call - Nodes list: status emoji column with relay hover tooltip; status filter uses `getStatusInfo` ### Tests - `relay_liveness_test.go`: index functions, relay metrics, wiring integration, bulk/single health endpoints - `test-repeater-liveness.js`: three-state frontend logic, backward compat ## Test plan - [x] Repeater with recent relay traffic shows green relaying emoji in list and detail pane - [x] Repeater with no relay traffic in 24h shows yellow idle in both views - [x] Repeater not heard recently shows grey stale in both views - [x] Non-repeater nodes unaffected (no relay stats, no status change) - [x] Hover tooltip on list emoji shows relay count and last relayed time - [x] `go test ./...` passes - [x] `node test-repeater-liveness.js` passes 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Sonnet 4.6 Co-authored-by: openclaw-bot --- Dockerfile | 2 -
