Description

Context

In config/cache.php you can define a separate connection to use for locks:
https://github.com/laravel/laravel/blob/f6e4638ee6ca1cd40aa7c56311d89ea3d91a24f8/config/cache.php#L74-L78

This makes it possible to run cache:clear without losing mutexes and atomic locks.
The lock_connection is used when calling

• Cache::lock(...)->get()
• Schedule::command(...)->withoutOverlapping()

It might be used in other contexts too, but those are the ones I'm aware of.

The problem

Schedule::command(...)->onOneServer() creates the lock on the regular cache connection via

framework/src/Illuminate/Console/Scheduling/CacheSchedulingMutex.php

Lines 41 to 46 in bcc9220

	public function create(Event $event, DateTimeInterface $time)
	{
	return $this->cache->store($this->store)->add(
	$event->mutexName().$time->format('Hi'), true, 3600
	);
	}

Which means that cache:clear will wipe those locks and allow another server to pick up the task.

Thoughts

I'm not familiar enough with the source to send a PR, and I don't know if there's a good reason for this behavior. Naively I would assume that onOneServer() should use CacheEventMutex in stead of CacheSchedulingMutex(which is apparently only used in this context).

Steps To Reproduce

1. Use a cache driver with a separate lock_connection
2. Configure a scheduled job with onOneServer(), which calls sleep(60).
3. Run schedule:run
4. Observe where the lock is stored.
