Add IdlewatcherNotifyConfig on IdlewatcherConfigBase so routes can opt into notifications for idlesleep state changes, and IdlewatcherDefaults for the matching global section. The config lives on the base rather than IdlewatcherConfig so it survives the base-only copy that NewWatcher does when reusing a watcher on reload. Enabled is a *bool alongside To because "notify all my channels" and "opt this route out of the global default" are both inexpressible with the acl.notify convention of treating a non-empty To as the opt-in, and the latter has no Docker label spelling at all. With Enabled unset, the acl ergonomic still applies: naming providers turns it on. Nothing dispatches yet; this only parses, validates and resolves.

Dispatch sleep/wake transitions through the configured notification providers. Idle routes previously sent no notifications of any kind: routeimpl assigns the watcher as the route's HealthMon instead of a health monitor, and the watcher's own monitor is never started, so notifyServiceUp/Down never fire for them. Hooks go on the four setX functions in state.go rather than on storeState, because teardown and the initial status store call storeState directly and must stay silent. Dispatch is edge triggered on a dedicated notifyPhase rather than on lastIdleAction, which sendEvent overwrites for every wake sub-event; on the request path it holds waiting_ready by the time setStarting runs and would fail to dedupe the setStarting that follows from the container event stream. The phase is recorded before the event filter so a filtered-out event still advances it. Also notify on the two wake() failure paths, which report through sendEvent but never reach setError, so a route whose dependency fails to start would otherwise report nothing at all.

Let sleep/wake notifications be turned on for every idle route at once, with routes still able to override in either direction. Defaults.Idlewatcher is a narrow IdlewatcherDefaults wrapper rather than IdlewatcherConfigBase on purpose: a global idle_timeout default would silently satisfy Route.UseIdleWatcher for every container-backed route. The merge only touches routes that already have an idlewatcher config, so `json:"idlewatcher,omitempty"` still holds for the rest. `to` is deliberately not cross-validated against providers.notification. initNotification runs as IssueDegraded, so a transiently broken provider would otherwise become a hard validation failure on every idle route. acl.notify.to is unvalidated for the same reason. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Expose sleep/wake notification config through container labels, so compose-only users can opt in per route instead of only globally through defaults.idlewatcher.notify. idlewatcherLabels values become dot separated key paths, and loadDeleteIdlewatcherLabels builds the intermediate objects, because notify is a nested object while the existing idlewatcher labels are all flat. serialization handles the rest: it recurses into map[string]any and splits comma separated strings into slices. The idle_ prefix scopes these against the existing un-namespaced idlewatcher labels, and leaves proxy.healthcheck_notify_* free later. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Picks up IdlewatcherNotifyConfig and IdlewatcherNotifyEvent, and the notify field on IdlewatcherConfig. The WebUI's src/lib/api.ts is generated from this file, and its route schema puts additionalProperties: false on the nested idlewatcher object, so without this the config editor would reject idlewatcher.notify. Generated with swag v1.16.6, which reproduces the previously committed output byte for byte apart from these additions. The load_avg key reordering is the generator's own alphabetical sort.

resolve() materialized the built-in [sleep, wake] set into Events, and it runs at deserialization time via the CustomValidator hook, before routevalidate.finalize gets to offer the globals. ApplyDefaults then saw a non-empty Events and skipped the inheritance, so defaults.idlewatcher.notify.events was never applied to any route. It applied to every route with an idlewatcher block, not just those declaring a notify block, because IdlewatcherConfig.validate() calls Notify.resolve() too. resolve() now computes the mask without touching Events, and ApplyDefaults materializes the built-in set only after the globals have had their turn. Also corrects the notification tests, which seeded no phase and so asserted that a watcher already in the asleep phase reports a sleep. It does not, by design: a container that was already stopped when the watcher was created has not transitioned. The helper now starts awake, which is the real precondition for observing a sleep, and the startup seeding keeps its own tests. Reported by CodeRabbit on yusing#264.

Thanks for the PR. It seems changing/adding much more code than needed for this feature... Opus 5 🤦. |
No behaviour change. - derive event bits from one ordered slice instead of a parallel map and a separate mask constant - fold the mask helper into resolve, and table-drive the per-event title, level and colour - collapse 17 notification test functions into a dispatch table plus the few cases needing their own assertions - merge three overlapping event-inheritance tests into one table Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Cuts the feature back to what was actually asked for: tell me when a
route sleeps or wakes.
Removed the `events` config field and its vocabulary, along with the
ready, error and sleep_failed notifications and their hooks. Those were
invented rather than requested, and they carried an enum, a bitmask,
validation, normalisation, a swagger definition and their own tests.
What remains is `notify: {enabled, to}`, per route or globally under
defaults.idlewatcher.notify, firing on sleep and wake.
Config surface, correctness and coverage are otherwise unchanged: the
phase edge-trigger, the startup seeding and the dependency suppression
all stay, since without them the notifications are simply wrong.
1406 -> 856 lines overall, 353 -> 212 of production code.

Fair, and thanks for looking. I went through it in two passes. First I tried to keep the functionality and just write it tighter — derived the event bits from one ordered slice instead of a parallel map, folded the mask helper into So I cut the surface. The 1406 → 856 lines; production code 353 → 212. What I kept, and would push back on cutting, is the phase edge-trigger, the startup seeding and the dependency suppression. They are not polish — without them you get duplicate alerts, a phantom wake for every already-running container at boot, and doubled notifications for anything used as a dependency. When I finally ran the tests, six of them failed on exactly the seeding semantics, so that one is load-bearing rather than theoretical. Also fixed the inheritance bug CodeRabbit caught, which was real and worse than reported: it affected every route with an Companion PR yusing/godoxy-webui#20 is updated to match.

Idlesleep transitions are currently only visible in the WebUI (per-watcher SSE and the Live Activity feed). This sends them through the existing
providers.notificationchannels, opt-in per route or globally.Worth noting: idle routes emit no notifications today.
routeimplassigns the watcher as the route'sHealthMoninstead of a health monitor, and the watcher's own monitor is never started, sonotifyServiceUp/Downnever fire for them. An operator running idlesleep gets silence.Config
