Yii2 队列扩展，Redis 驱动中，info 命令打印关于队列状态的信息时，reserved 状态的队列的删除

• 编程笔记

1、查看 log 表，其 message 字段内容如下：

2、分析发现，发布文章队列事件处理器，发布文章队列的作业执行失败后，common/components/queue/PubArticleEventHandler::afterError(ExecEvent $event)，在此方法中抛出异常，一旦抛出异常，进而便会导致此发布文章队列的状态一直处于：reserved，因此，应该尽可能避免在此方法中抛出异常

3、Yii2 队列扩展，Redis 驱动中，info 命令打印关于队列状态的信息时，reserved 状态的队列数量为 33，如图1

[root@cc121bb54862 /]# cd /mcloud/www/channel-pub-api/
[root@cc121bb54862 channel-pub-api]# ./yii copy-asset-queue/info --color=0
Jobs
- waiting: 0
- delayed: 0
- reserved: 0
- done: 146
[root@cc121bb54862 channel-pub-api]# ./yii upload-asset-queue/info --color=0
Jobs
- waiting: 0

[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/info --color=0
Jobs

Jobs
- waiting: 0
- delayed: 0

4、由于 Supervisor 仅启动 1 个 queue/listen，因此，一旦某一队列处于 reserved，则其他队列只好一直处于 waiting 状态，所以，临时决定 remove 命令删除作业，以启动程序的继续正常运转，查看 log 表，其 message 字段内容，可以确定队列 ID 值为：159，info 命令打印关于队列状态的信息时，reserved 状态的队列数量减少 1，done 状态的队列数量增加 1，符合预期，如图2

5、基于以上流程，重复地分别执行 remove 命令删除作业，等待一段时间后，info 命令打印关于队列状态的信息时，reserved 状态的队列数量持续减少中，done 状态的队列数量持续增加中，符合预期

[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/info --color=0

- delayed: 0
- reserved: 33
- done: 164
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/remove 184
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/info --color=0
Jobs
- waiting: 17
- delayed: 0
- reserved: 33
- done: 165
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/remove 175
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/info --color=0
Jobs
- waiting: 18
- delayed: 0
- reserved: 30
- done: 167
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/remove 141
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/info --color=0
Jobs
- waiting: 18
- delayed: 0
- reserved: 29
- done: 168
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/remove 168
[root@cc121bb54862 channel-pub-api]# ./yii pub-article-queue/info --color=0
