Driver [redis-sentinel] is not supported.

[adamzwakk]

Hey guys,

Just installing the driver and setting the .env files, and I'm getting the error Driver [redis-sentinel] is not supported. on my Laraval 5.5 instance (it seems to hit that in Illuminate/Cache/CacheManager.php)

I'm using the default vars

CACHE_DRIVER=redis-sentinel
SESSION_DRIVER=redis-sentinel
QUEUE_DRIVER=redis-sentinel
REDIS_DRIVER=redis-sentinel

REDIS_HOST=localhost
REDIS_PORT=26379
REDIS_SENTINEL_SERVICE=mymaster
REDIS_CACHE_DATABASE=1
REDIS_SESSION_DATABASE=2
REDIS_QUEUE_DATABASE=3

with localhost being where redis/redis-sentinel is installed, but it doesn't seem to see the driver. Any ideas? Did I miss something?

Hey Adam, the package's service provider needs to boot() before the drivers become available. Laravel does this automatically, but the cache service cannot find the Sentinel driver if something in the application tries to access the cache before that happens (for example, if another service provider uses the cache in its register() method).

If you're using Laravel 5.5's package autoloading to register this package's service provider, and your project uses another package with a service provider that happens to autoload before this one (and it uses the cache), the driver may not be available yet because Laravel executes the other one first. You can manually register this package's service provider in config/app.php to fix the dependency order.

I've added it to "dont-discover" list in composer.json, and trying to load it manually at the top of app.php, same result.

What's interesting though if I don't have the provider entry, the error turns into Cache store [redis-sentinel] is not defined. which is expected, but with the entry, I get Driver [redis-sentinel] is not supported.

So it's definitely being detected in some way anyways, I'll keep poking at it

[cyrossignol]

As you found, putting it at the top of the 'providers' array in config/app.php before Laravel's built-in service providers won't work because the binding gets wiped out when Laravel's own cache service provider executes afterward.

Try putting the entry after Laravel's built-in providers, but before any other package or app-specific providers. The scenarios you described above seem to validate the theory that something's trying to access the cache service before the package's provider boots. If you get the same error after this, try to find a service provider that uses the cache in its register() method. If you find one, you may need to move that logic to the provider's boot() method. The stack trace should help to identify where the cache is being accessed from.

The offending package seems to be Waavi/translation, commenting out that package in favor the default one seems to let sentinel load :)

I'll poke them and ref this issue, thanks for the help!

I'm also running into this issue with Lumen 5.7. The update defers the provider boot until passed to the Kernel/router to handle, that breaks the Kernel as it references Cache prior to booting the providers as part of setting up the schedule (https://github.com/laravel/lumen-framework/blob/26e830b9e81eb4dff2b1df0f5b0755cb7a5e9cbe/src/Console/Kernel.php#L97-L99).

Previous versions booted providers immediately so there wasn't any issue. I'm working around it by booting the providers before handing off to the Kernel but given how vital cache is it might be worth setting up immediately instead of deferring?

[cyrossignol]

Dave, thanks for bringing that up. I'd consider that a bug in Lumen--the framework isn't respecting the convention that Laravel sets for the interoperability of its service providers. At this point, however, it's probably easier to to just update the package.

Personally, I don't mind booting the drivers during provider registration. I considered writing the package that way initially, but I followed Laravel's convention instead. This is a breaking change, though. I think we can add a config directive at first (redis-sentinel.auto_boot = true) and refactor the package later if we can get rid of the overhead.

Let me know your thoughts.

[dave-lang]

Thanks for the quick reply, I agree - it's a Lumen issue and I've logged it on the framework (laravel/lumen-framework#844).

I think an auto boot config for would be a good addition, not just for framework issues but for handling inter-op issues with other providers and packages that don't follow the recommended register/boot convention.

It should be a simple, if autoboot set (config or env) boot the provider, if booting check whether already booted (as the framework will try to re-boot it). I can submit a pull request tonight if needed?

[cyrossignol]

That sounds great--thanks! I'm sure @adamzwakk will be happy for the fix as well.

The Same issue ocurrs when overriding the SessionServiceProvider, like described here.

I've found no way to solve the Driver [redis-sentinel] not supported. issue.

[cyrossignol]

@matrad Sorry, I missed the email for your comment.

This sounds like the same issue described in the rest of this ticket: one of the service providers in your application seems like it's trying to call Laravel's session service during the registration phase before this package's service provider boots.

I merged @davoaust's changes that provide a workaround this issue. Please install the 2.x-dev version of this package and set REDIS_SENTINEL_AUTO_BOOT=true in the .env file.

If this works for you, I will release a new stable version of this package with these changes.

[cyrossignol]

Auto-boot improvements by @dave-lang finally released in version 2.6.0. This provides a workaround for applications and other packages that depend on Sentinel services before the application finishes the boot() phase.

Please comment if the issue persists after enabling the package's auto-boot option.
