Celery: L'arrêt à chaud ne fonctionne pas comme prévu depuis la v4

Étapes à reproduire

Lancez simplement une simple configuration de céleri et essayez Ctrl^C pour simuler un comportement d'arrêt à chaud avec la dernière version de Celery. Cela [ne fonctionne pas comme annoncé] : (http://docs.celeryproject.org/en/latest/userguide/workers.html#stopping-the-worker) le travailleur ne peut pas attendre que toutes les tâches soient terminées car le processus principal se termine brusquement avec une exception. Voir la sortie du journal ci-dessous où je soumets une simple tâche d'ajout qui dort 30 secondes plusieurs fois afin que je puisse simuler une tâche de longue durée et si elle se poursuivrait lorsque le processus principal recevrait un SIGTERM .

[2018-12-26 14:59:13,109: DEBUG/MainProcess] removing tasks from inqueue until task handler finished

J'ai essayé exactement la même configuration avec la version 3.1.25 et cela semble fonctionner très bien, le travailleur principal attend la fin de toutes les tâches, puis se termine.

Cela est devenu un problème critique pour nous depuis la mise à niveau vers la dernière version de Celery, car nous ne sommes plus en mesure de déployer de manière fiable pour les travailleurs. Bien que recommandé, malheureusement, toutes nos tâches ne sont pas idempotentes, donc une tâche qui est tuée au milieu de l'exécution est un gros problème.
