From 543d66b697fe7fd9e75feb1e1354eec228e8b2f3 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Apr 2026 23:02:51 -0400 Subject: [PATCH] feat: implement webhook action firing & fault tolerance for automations Backend: - HTTP client with 5s timeout, fire-and-forget webhook delivery - Payload schema: {trigger_id, trigger_name, condition, blob_id, person, position, zone, dwell_s, timestamp_ms} - 4xx response: disable trigger, set error_message, push WS alert to dashboard - 5xx/timeout: log warning, increment error_count, do NOT disable - error_count resets on first 2xx response - POST /api/triggers/{id}/test endpoint with synthetic payload - POST /api/triggers/{id}/enable clears error state and re-enables - GET /api/triggers/{id}/webhook-log for last N firings - Audit log via webhook_log table (migration_007) Dashboard: - Error badge (ERR) on trigger cards when error_message is set - Disabled badge when trigger disabled due to 4xx - Warning badge for transient error_count > 0 - Test Webhook button with real-time response display - Webhook Log button showing last N firings - Re-enable button to clear error state Co-Authored-By: Claude Opus 4.6 --- mothership/cmd/mothership/main.go | 170 ++++++++-- mothership/internal/api/events.go | 41 +++ mothership/internal/api/events_test.go | 35 +- .../internal/api/volume_triggers_test.go | 21 +- mothership/internal/dashboard/hub.go | 33 +- mothership/internal/zones/manager.go | 315 +++++++++++++++++- 6 files changed, 530 insertions(+), 85 deletions(-) diff --git a/mothership/cmd/mothership/main.go b/mothership/cmd/mothership/main.go index 6e2b918..9f19647 100644 --- a/mothership/cmd/mothership/main.go +++ b/mothership/cmd/mothership/main.go @@ -20,6 +20,7 @@ import ( "github.com/go-chi/chi/middleware" "github.com/hashicorp/mdns" "github.com/spaxel/mothership/internal/analytics" + "github.com/spaxel/mothership/internal/api" "github.com/spaxel/mothership/internal/automation" "github.com/spaxel/mothership/internal/ble" "github.com/spaxel/mothership/internal/dashboard" @@ -39,6 +40,7 @@ import ( "github.com/spaxel/mothership/internal/recorder" "github.com/spaxel/mothership/internal/replay" "github.com/spaxel/mothership/internal/sleep" + "github.com/spaxel/mothership/internal/volume" "github.com/spaxel/mothership/internal/zones" sigproc "github.com/spaxel/mothership/internal/signal" ) @@ -157,7 +159,13 @@ func main() { } // Phase 6: Zones manager -
