Go backend:
- Add OTel SDK + otelhttp middleware deps (go.mod)
- New internal/otelsetup package: init OTLP/HTTP TracerProvider from env vars
- cmd/backend/main.go: call otelsetup.Init() after logger + ctx setup
- internal/backend/server.go: wrap mux with otelhttp.NewHandler() before
sentryhttp, so all HTTP spans are recorded
SvelteKit UI:
- Add @opentelemetry/sdk-node, exporter-trace-otlp-http, resources,
semantic-conventions
- hooks.server.ts: init NodeSDK when OTEL_EXPORTER_OTLP_ENDPOINT is set;
graceful shutdown on SIGTERM/SIGINT
Config:
- docker-compose.yml: pass OTEL_EXPORTER_OTLP_ENDPOINT + OTEL_SERVICE_NAME
to backend, runner, and ui services
- homelab/docker-compose.yml: fix runner OTel endpoint to HTTP port 4318
- Doppler prd: OTEL_EXPORTER_OTLP_ENDPOINT=https://otel.libnovel.cc
- Doppler prd_homelab: OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4318
All services no-op gracefully when the env var is unset (local dev).
Two bugs caused audio tasks to loop endlessly:
1. claimRecord never set heartbeat_at — newly claimed tasks had
heartbeat_at=null, which matched the reaper's stale filter
(heartbeat_at=null || heartbeat_at<threshold). Tasks were reaped
and reset to pending within seconds of being claimed, before the
30s heartbeat goroutine had a chance to write a timestamp.
Fix: set heartbeat_at=now() in claimRecord alongside status=running.
2. Audio semaphore was checked AFTER claiming the task. When the
semaphore was full the select/break only broke the inner select,
not the for loop — the code fell through and launched an uncapped
goroutine that blocked forever on <-audioSem drain. The task also
stayed status=running with no heartbeat, feeding bug #1.
Fix: pre-acquire a semaphore slot BEFORE claiming the task; release
it immediately if the queue is empty or claim fails.
- Runner fetches 9 browse combos (genre×sort×status) every 6h and stores
JSON snapshots in MinIO libnovel-browse bucket (browse_refresh.go)
- Backend handleBrowse reads page-1 results from MinIO first; falls back
to live novelfire.net fetch; returns empty+cached:false on total failure
instead of 502
- Add BrowseStore interface (bookstore.go), MinIO put/get helpers (minio.go),
Store methods + compile-time assertion (store.go), BucketBrowse config,
wiring in cmd/backend and cmd/runner, docker-compose-new bucket init
- Fix ReapStaleTasks: PocketBase datetime fields require heartbeat_at=null
(not heartbeat_at="") in filter expressions, and nil (not "") in patch
payload — was causing 400 errors on every reap cycle
- backend/: Go API server and runner binaries with PocketBase + MinIO storage
- ui-v2/: SvelteKit frontend rewrite
- docker-compose-new.yml: compose file for the v2 stack
- .gitea/workflows/release-v2.yaml: CI/CD for backend, runner, and ui-v2 Docker Hub images
- scripts/pb-init.sh: migrate from wget to curl, add superuser bootstrap for fresh installs
- .env.example: document DOCKER_BUILDKIT=1 for Colima users
