Although murder mysteries are not usually my thing, I had to give this one a shot because it features one of my favorite hobbies, Geocaching!

This was a well written book, with great characters and a smooth flowing story line.

Instead, I had to dig into the code to figure out why it was giving me an error. Not a big deal for me, but for the average user this would be virtually unsolvable. After that we won't need to call isSupported method on getConnection like at:.

Personally I'm not the biggest fan of checks like that in a constructor unless they are really the only place you can rely on them. It also doesn't really improve the messages much and I don't think we should be putting that level of server related detail into a message that is most likely going to be displayed to an end user because nothing is catching exceptions from the cache API.

Cache-cache a fatal field

We can create a storage instance manually when it is not supported like new JCacheStorageFile :. The best way would be to have all storages behave in the same way.

The Fatal Cache

Current joomla checks that before creating instance as a workaround. For the three connecting to an external server, as you pointed out before if we check if the configuration is valid to connect to the server in isSupported it blocks being able to configure the connection via the UI, so they have to do the added connection checks at runtime. In most cases this is basically if the underlying PHP requirements are met. For that part I don't think we need the isSupported checks in the constructors. So to me it's fair that isSupported is used independently of instantiating the class.

These types of checks really shouldn't be happening in the class' instantiation. If we had a proper service layer, that would be throwing the exceptions if the environment is unsupported or the runtime connections couldn't be established and the handlers would be left to just function with blissful ignorance to anything else in the environment, but sadly we aren't there yet.

Ok, then isSupported should be call before create a new instance of storage. Then check that again in contructor or geConnection is not needed. The other thing is that nothing is catching exceptions from cache. IMHO this should be changed. Cache only helps joomla and it should not block all page. If cache failed means throw exception then only error message should be generated for admin or end user. A more graceful recovery is good when possible , and a message at the admin side is enough to give time to the administrator users to fix the issue, without the site getting down for a "long" period.

This is only "fatal" because nothing catches and handles the exceptions thrown by the API. JCache itself should NOT be aware of the active application and it still pisses me off to no end there is code handling just that in the Redis adapter.

That's the point of having decoupled high level APIs like this one, our high level libraries shouldn't have intricate and difficult to trace inner dependencies such as active objects in JFactory all of those dependencies just make testing this code harder because you have to mock much more of the environment with "working" objects. It's not my fault the core CMS and the extension developers suck at catching exceptions.

And going back to the issue: corywebb Can you confirm that you used plugin System - Page Cache?

See a Problem?

I have cache completely disabled on the site, which is why I was surprised to be getting a fatal error about the cache system. The default templates with debug mode enabled will give a stack trace. Turn that on and try to trigger the error. If caching's disabled as you say and you're still getting this error then odds are that there is an extension trying to use the cache system anyway totally possible and valid and the trace will show what that is. I have the same error. Ok, I have to say that my hosting provider has disabled memcache and memcached for shared server.

Your Answer

Please, check the screenshots:. Step Stept Even if caching is disabled at a global level, data can still be cached by extensions, so it still needs to be possible to clear that cache data. When is that solution in a Joomla stable version?

  8. This happened on my site this morning and it's not the only time. I think the last time is months before. It's so scary cause I have to reboot the whole sever to make my site working! So, the memcached server was really broken?

    No, you are off-topic, memcached is not broken, if you think it is broken you should open a new issue. Now about the topic discussed in this thread, the alternative is to silently ignore the error and continue working even if the configured caching system is not available The fact that the caching configuration was hidden when people disable the "view" caching parameter in global configuration was wrong,. In next Joomla version it will alway be shown, see the picture:. The apc Cache Storage is not supported on this platform. The file Cache Storage is not supported on this platform.

    So the problem is - Cache is disabled, why the server throws this error - this is new installation, no cache plugin enabled, no 3pd plugin installed - fresh install. FTP layer is enabled and the cache folders site, admin are the same owner as FTP and are writable by this owner. BUT caching is disabled. Skip to content.
