"""Unit tests for the per-worker active-call registry (deploy draining).
|
|
|
|
The registry backs GET /api/v1/health/active-calls, which scripts/rolling_update.sh
|
|
(and a k8s preStop hook) polls to wait for live calls to finish before stopping a
|
|
worker. The guarantees that matter for draining: register/unregister are
|
|
idempotent, and the count only reaches zero when every registered run is gone.
