python - django-q 任务队列：失败的任务会一直处理下去

问题描述

任何使用 django-q 任务调度程序的人：https ://github.com/Koed00/django-q ？

（不是数据库相关Q库）

我有一堆失败的任务。每次我运行 django-q 时，这些失败的任务都会不断弹出：

18:06:14 [Q] INFO Process-1:9 processing [apart-sixteen-butter-friend]
18:06:14 [Q] INFO Process-1:10 processing [single-mississippi-bravo-fillet]

18:06:15 [Q] ERROR reincarnated worker Process-1:4 after death

这些失败任务中提到的相关问题已得到修复。然而，失败的任务不断出现。即使我从数据库（django_q_task表）中删除失败的条目，每次运行qcluster命令时都会重新创建它们。

如何处理此问题并阻止这些错误出现在输出中？

解决方案

它是新添加的配置：您可以根据此拉取请求attempt_count设置为 1 。

max_attempts不够好且令人困惑 -因为最小重试次数为 1 - 所以失败任务的总调用次数为 2。

'ack_failures': True请记住，如果引发 an ，您还需要设置Exception- 以确认失败。

令人困惑但可行的是：

Q_CLUSTER = {
    'name': 'DjangORM',
    'workers': 1,
    'timeout': 600,
    'orm': 'default',
    'save_limit': 0,
    'ack_failures': True,
    'max_attempts': 1,
    'attempt_count': 1
}
