…is used (moufmouf) This PR was squashed before being merged into the 3.4 branch (closes #32025). Discussion ---------- SimpleCacheAdapter fails to cache any item if a namespace is used | Q | A | ------------- | --- | Branch? |3.4 | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | License | MIT 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 `SimpleCacheAdapter` to "_" (that is compatible with PSR-16). The first commit of this PR starts with an additional test and no fix (to showcase the problem). Commits ------- ffd3469 SimpleCacheAdapter fails to cache any item if a namespace is used

The Psr16Adapter extends AdapterTestCase.
