# Upgrade to 1.11
|
||
|
|
|
||
|
|
doctrine/cache will no longer be maintained and all cache implementations have
|
||
|
|
been marked as deprecated. These implementations will be removed in 2.0, which
|
||
|
|
will only contain interfaces to provide a lightweight package for backward
|
||
|
|
compatibility.
|
||
|
|
|
||
|
|
There are two new classes to use in the `Doctrine\Common\Cache\Psr6` namespace:
|
||
|
|
* The `CacheAdapter` class allows using any Doctrine Cache as PSR-6 cache. This
|
||
|
|
is useful to provide a forward compatibility layer in libraries that accept
|
||
|
|
Doctrine cache implementations and switch to PSR-6.
|
||
|
|
* The `DoctrineProvider` class allows using any PSR-6 cache as Doctrine cache.
|
||
|
|
This implementation is designed for libraries that leak the cache and want to
|
||
|
|
switch to allowing PSR-6 implementations. This class is design to be used
|
||
|
|
during the transition phase of sunsetting doctrine/cache support.
|
||
|
|
|
||
|
|
A full example to setup a filesystem based PSR-6 cache with symfony/cache
|
||
|
|
using the `DoctrineProvider` to convert back to Doctrine's `Cache` interface:
|
||
|
|
|
||
|
|
```php
|
||
|
|
use Doctrine\Common\Cache\Psr6\DoctrineProvider;
|
||
|
|
use Symfony\Component\Cache\Adapter\FilesystemAdapter;
|
||
|
|
|
||
|
|
$cachePool = new FilesystemAdapter();
|
||
|
|
$cache = DoctrineProvider::wrap($cachePool);
|
||
|
|
// $cache instanceof \Doctrine\Common\Cache\Cache
|
||
|
|
```
