description

Implements and reviews dubbo-admin EventBus dispatching. Use when the user asks about Event, Emitter, Subscriber, SubscriptionManager, EventBus component registration, Subscribe or Unsubscribe behavior, Send dispatch rules, subscriber ProcessEvent flow, resource-kind based routing, or event error handling under pkg/core/events/. Do not use for a domain subscriber unless the task changes the event bus contract or dispatch semantics.

dubbo-admin Events

Purpose

Use this skill to modify or explain the shared EventBus contract used by discovery, engine, informers, and subscribers.

When to use

Use for EventBus interfaces, resource-kind dispatching, subscriber registration uniqueness, synchronous processing, and event dispatch error behavior.

Do not use for business logic inside a single subscriber unless EventBus semantics change.

Inputs

Required:

• EventBus behavior, interface, or dispatch problem.
• Event producer or subscriber involved.

Optional:

• Event type.
• Old and new resource objects.
• Subscriber names for the same resource kind.

If missing, inspect pkg/core/events/eventbus.go and pkg/core/events/component.go first.

Workflow

1. Read pkg/core/events/eventbus.go for Event, Emitter, Subscriber, SubscriptionManager, and EventBus interfaces.
2. Read pkg/core/events/component.go for the concrete EventBus implementation.
3. Trace producers that call events.NewResourceChangedEvent and Emitter.Send.
4. Trace consumers implementing ResourceKind, Name, and ProcessEvent.
5. Read references/eventbus-dispatch.md before changing dispatch semantics.
