The five counts the cache_stats table held are now Prometheus counters in memory, as fields of the cache. NewCache makes them and registers them on the registry it is given. pixad gives it Prometheus' default registry, which /metrics serves; each test gives it a new one. The Increment methods add to their cache's counters, so counting makes no database call. cache_stats, Cache.Stats, Service.Stats, CacheStats and the pending counts are gone, with their tests. The background goroutine now writes only access times, and its names say so: StartPendingAccessTimeWrites, StopPendingAccessTimeWrites and pendingaccesstimes.go. The two stop tests whose write under way was a count now use access times. Model: opus-5-5
