Description
Fixes #28.
The documentation stated that an invalid cache key (empty, or with reserved characters) always throws a
Psr\Cache\InvalidArgumentException. Symfony adapters only validate the keys withassert(): withzend.assertions=-1(productionphp.ini), invalid keys are silently accepted.reference/adapter.md: the keys are validated by the decorated pool, withassert()for Symfony adaptersreference/tasks/set_task.md,get_task.md: a placeholder key''not overridden by the input is rejected only when assertions are enabled; in production, every item is stored / read under the same empty keyChecked with
ArrayAdapterandFilesystemAdapter:InvalidArgumentExceptionwithzend.assertions=1, item stored and read back withzend.assertions=-1.Requirements
Breaking changes
None (documentation only).
