faveo/vendor/doctrine/cache/UPGRADE-1.11.md

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:

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
