What

The SubManagedCycle IPC handler called ForceCycle() synchronously, which chains through runCycle → fetchMembers → ListNodes — a network call to the registry with no timeout. A hung or slow registry would wedge the IPC handler goroutine indefinitely.

Fix

Wrap the ForceCycle call in a background goroutine with a 5-second context.WithTimeout. On timeout, the handler returns an error to the client; the background goroutine completes the cycle asynchronously so peer state is still eventually refreshed.

Verification

  • go build ./...
  • go vet ./...
  • go test -parallel 4 -count=1 -timeout 900s ./pkg/daemon/ ✅ (58.9s, all pass)

Scope

  • 1 file, +23/-6 — small tier

Closes PILOT-309

ForceCycle called from the IPC handler was a synchronous call to
runCycle → fetchMembers → ListNodes, which is a network call with no
timeout. A hung or slow registry would wedge the IPC handler goroutine
indefinitely, denying service to that IPC client.

Wrap the ForceCycle call in a background goroutine with a 5-second
context deadline. On timeout, the handler returns an error to the
client; the background goroutine completes the cycle asynchronously
so peer state is still eventually refreshed.

Closes PILOT-309

🔍 PR Explanation — #202 PILOT-309

What this does

Wraps the SubManagedCycle IPC handler's ForceCycle() call in a background goroutine with a 5-second timeout, preventing a hung or slow registry from wedging the IPC handler indefinitely.

The problem

SubManagedCycle called ForceCycle() synchronously, which chains through runCycle → fetchMembers → ListNodes — a network call to the registry with no timeout. A hung or slow registry would wedge the IPC handler goroutine indefinitely.

The fix

In pkg/daemon/ipc.go (+31/−8):

  • Creates a context.WithTimeout(ctx, 5*time.Second) for the force-cycle operation
  • Runs ForceCycle() in a background goroutine
  • Selects between the done channel and ctx.Done():
    • On timeout: returns an error to the IPC client immediately; the background goroutine still completes the cycle asynchronously
    • On success: returns nil

Design choices

  • 5-second timeout provides ample headroom for normal registry responses while preventing indefinite hangs
  • Background goroutine continues cycle completion even after timeout — peer state eventually converges
  • Non-blocking behavior for the IPC client — they get immediate feedback instead of hanging

Scope

  • 1 file, +31/−8 — small tier (≤3 files, ≤50 LoC)

📋 PR Explanation — PilotProtocol #202

What: Adds a 5-second timeout to the SubManagedCycle IPC handler in the daemon.

Why (PILOT-309): Without a timeout, the IPC handler for managed-cycle subscription can block indefinitely if the remote end fails to respond, tying up a goroutine and potential resources. The fix wraps the blocking send with context.WithTimeout.

Risk: Low (the timeout is generous at 5s; normal IPC completes in milliseconds).

Review focus: pkg/daemon/ipc.go — the SubManagedCycle method, where the context timeout is added around the blocking IPC call.
