Laravel非重叠计划作业未执行 [英] Laravel non-overlapping scheduled job not executing

问题描述

我有一个Laravel Scheduled作业，它在Kernel.php中定义，就像这样

I have a Laravel Scheduled job which is defined in Kernel.php like so

$schedule->call('\App\Http\Controllers\ScheduleController@processQueuedMessages')
    ->everyFiveMinutes()
    ->name('process_queued_messages')
    ->withoutOverlapping();

在开发过程中，由于语法错误，我的工作引发了异常.我更正了该错误，然后尝试再次执行该错误；但由于某种原因，它不会.

During development, my job threw an exception due to a syntax error. I corrected the error and tried executing it again; but for some reason it won't.

我尝试了artisan down，然后尝试了artisan up.我也尝试过重新启动服务器实例.但是没有任何帮助.作业只是没有执行(也没有例外).

I tried artisan down and then artisan up. I also tried restarting the server instance. But nothing would help. The job just didn't get executed (there was no exception either).

我意识到问题出在->withoutOverlapping()上. Laravel调度程序以某种方式认为该作业已经在运行，因此不再执行.

I realize that the problem is due to ->withoutOverlapping(). Somehow, Laravel scheduler is thinking that the job is already running and hence is not executing it again.

推荐答案

我通过查看供应商代码找到了解决方案.

I found the solution by looking at the vendor code.

Illuminate\Console\Scheduling\CallbackEvent.php

它将在本地存储中创建一个名为schedule-*的文件.

It creates a file in local storage with the name schedule-*.

public function withoutOverlapping()
{
    if ( ! isset($this->description))
    {
        throw new LogicException(
            "A scheduled event name is required to prevent overlapping. Use the 'name' method before 'withoutOverlapping'."
        );
    }

    return $this->skip(function()
        {
            return file_exists($this->mutexPath());
        });
}

protected function mutexPath()
{
    return storage_path().'/framework/schedule-'.md5($this->description);
}

在storage/framework处删除文件schedule-*解决了该问题.

Deleting the file schedule-* at storage/framework resolved the issue.
