Fixed.

I'm rebasing to make sure the new test is actually run.

Hi @derrabus @greg0ire,

Priori to this PR I use

$query = $this->createQueryBuilder('foo')->(...)->getQuery();

if ($invalidateCache) {
     $query->getQueryCacheDriver()?->delete(self::CACHE_KEY);
}

return $query->enableResultCache(self::CACHE_LIFETIME, self::CACHE_KEY)->getOneOrNullResult();

What would be the new way to achieve the same behavior now getQueryCacheDriver is deprecated ?

I'd like to be able to delete a specific cache entry, and this PR doesn't introduce a getQueryCache method.

$configuration->getQueryCache() would be the way I suppose.

$configuration->getQueryCache() would be the way I suppose.

Thanks, I can indeed solve it with

$queryCache = $this->getEntityManager()->getConfiguration()->getQueryCache();
$queryCache?->deleteItem(self::CACHE_KEY);
