Add WorkerdDebugPort interface for dynamic RPC entrypoint access Introduces a new privileged debug port interface that enables dynamic access to worker entrypoints at runtime. Currently, service bindings between workerd processes must be configured at startup in the config file. Changing binding targets requires a full process restart. This is problematic for local development tools like Miniflare, which need to dynamically re-target RPC connections at runtime. Today, Miniflare works around this by running a Node.js TCP server that sits between workerd processes and manually re-routes RPC traffic. This adds significant complexity and overhead. This commit implements the WorkerdDebugPort interface which exposes all service entrypoints in a process through a privileged RPC interface. External tools can now: - Get direct access to any entrypoint with custom props at runtime - Start events and invoke methods via JS RPC without HTTP overhead - Dynamically switch between entrypoints without process restarts This enables Miniflare to eliminate its TCP proxy layer and handle dynamic RPC routing natively through workerd. ``` interface WorkerdDebugPort { getEntrypoint(service, entrypoint, props) -> (worker) getActor(service, entrypoint, actorId) -> (actor); } ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
