charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove unsafe Docker fallback that could kill wrong container in multi-run environments; containers have no run ID label so matching is impossible — replaced with a warning log - Add unsubscribeFromCancelCommands() to queue/cancel.ts so the Redis subscriber connection is properly closed on graceful shutdown - Replace misleading type hack (cancelSubscriber = true as unknown as ...) with a clear boolean flag (cancelSubscriberActive) - Remove redundant cascadeContainers.length > 0 check that was always true after the early return guard - Update tests to cover new warning-log behavior and verify shutdown properly calls unsubscribeFromCancelCommands Co-Authored-By: Claude Opus 4.6 --- src/queue/cancel.ts | 17 +++ src/router/cancel-listener.ts | 91 +++----------- tests/unit/router/cancel-listener.test.ts | 137 ++++++---------------- 3 files changed, 70 insertions(+), 175 deletions(-) diff --git a/src/queue/cancel.ts b/src/queue/cancel.ts index 559611cb..e517e391 100644 --- a/src/queue/cancel.ts +++ b/src/queue/cancel.ts @@ -91,3 +91,20 @@ export async function subscribeToCancelCommands(handler: CancelCommandHandler): await subscriber.subscribe(CANCEL_CHANNEL);
