unable to update machine IP in database: %w
Error message
unable to update machine IP in database: %w
What it means
UpdateMachineIP returns the raw ent error when Machine.UpdateOneID(id).SetIpAddress(ipAddr).Save(ctx) fails. Like the scenarios updater, it runs during Authenticator; ent returns a not-found error if the row id no longer exists, or a driver error if the DB is unavailable.

Solutions
- Read the wrapped ent error to distinguish not-found from driver failure
- Treat ent not-found as benign (machine gone) and return/refresh state
- Re-query the machine by machine_id and retry the update with fresh data
- Check DB connectivity and lock contention if errors are frequent
Defensive patterns
Strategy: try-catch
Validate before calling
m, err := db.QueryMachineByID(ctx, machineID)
if err != nil { return err }
_ = m.ID // fresh id guaranteed present before UpdateMachineIP Try / catch
if err := db.UpdateMachineIP(ctx, ip, id); err != nil {
// unwrap and log; if ent not-found, refresh the machine row and retry once
return fmt.Errorf("ip update for machine %d: %v", id, err)
} Prevention
- Fetch rows via QueryMachineByID immediately before id-based writes
- Serialize prune with authentication traffic or tolerate benign not-found
- Use a server DB to reduce SQLite lock failures on busy LAPIs
- Log the underlying ent error, not just the wrapper
When it happens
Trigger: Authenticator updates the watcher's IP on each successful auth; fails when the machine row was deleted concurrently, the DB is locked/down, or the new ipAddr violates a column constraint.
Common situations: Prune removing unvalidated machines mid-auth; watcher IP changed behind NAT/proxy triggering an update against a stale id; SQLite write contention.
