Add defer-recover to 11 goroutines across 4 files to prevent
ungoroutine panics from crashing the entire process:
- pkg/tools/toolloop.go: parallel tool execution
- pkg/channels/manager.go: HTTP server (x2), channel registration
- pkg/events/subscription.go: concurrent dispatch, timeout handler,
watchContext
- pkg/tools/shell.go: cmd.Wait, PTY cmd.Wait, PTY read, pipe read
Key design decisions:
- Recover handlers send fallback values to channels (shell done,
subscription done) to prevent deadlocks when the producer panics
- PTY cmd.Wait sets session.Status='error' on panic for consistency
- toolloop sets ErrorResult on panic so the LLM gets a meaningful
response instead of a nil result
- subscription.go uses log.Printf to match existing invokeHandler style
- Other files use project logger (ErrorCF) with stack traces
Refs: FIX-PLAN-0.3.0 #2
Add a non-blocking runtime publish path and switch hot-path publishers to it.
Enforce subscription timeout boundaries, keep ordered subscriber snapshots up to date on subscribe changes, expose all runtime kinds to process hooks, add safe log attrs for non-agent events, and close the gateway message bus on full shutdown.
Introduce pkg/events with filtered channels, subscription policies, backpressure, and stats. Wire AgentLoop to dual-publish legacy agent events into runtime events while preserving old event APIs.
Validation: go test ./pkg/events/... ./pkg/agent; go test -race ./pkg/events/...; make lint
