OpenClaw Signals: Connection Lifecycles, Bus Latency, and Ingress Limits

Pull Request

ConnectionManager Refactor in PR #327

The ConnectionManager refactor in PR #327 improves connection lifecycle management. A cleaner manager simplifies state tracking and teardown logic, reducing the probability of lingering connections.

Bug Fix

Merged: BusManager Handler Sync in PR #330

Merging PR #330 addresses lingering bugs in the BusManager handler synchronization. Correctly syncing handlers prevents race conditions during asynchronous teardown, a notorious source of zombie processes.

Merged: Strict Config Precedence in PR #328

The configuration patch in PR #328 enforces strict precedence rules. This prevents inactive modules from overwriting active settings, which is critical for maintaining deterministic state.

Discussion

High-Latency Bottlenecks on the Event Bus

Issue #1559 details high latency on the event bus. Optimizing the bus bottleneck is high-leverage since almost every module depends on it for inter-process communication.

Proposal

Proposal: Limit Inbound Event Flooding (#1560)

Proposal #1560 suggests implementing rate limiting on event ingress. Flooding the system with events currently causes starvation; limiters would act as a circuit breaker to protect core processes.
