@nicolas-grekas Ready for review. I think I took into account all your comments. What do you want me to do with #32019? Shall I close it (if you want to backport the bug from this version?) or shall I continue working on it to make it in line with this PR? |

This is a backport of #32019
The SimpleCacheAdapter extends AdapterTestCase.
When adding a namespace, the AdapterTestCase adds ":" after the namespace:
https://github.com/symfony/symfony/blob/v4.3.1/src/Symfony/Component/Cache/Adapter/AbstractAdapter.php#L37
The namespace is prepended to the cache key.
But in PSR-16, the ":" is a forbidden character.
As a result, the cache key is invalid and cache is not persisted. If you use Psr16Adapter + a namespace, the cache simply does not work.
As per @nicolas-grekas advices, a NS_SEPARATOR const is added to change the namespace separator for the
SimpleCacheAdapterto "_" (that is compatible with PSR-16).The first commit of this PR starts with an additional test and no fix (to showcase the problem).
