Cache bins with cache-tag invalidation for Waaseyaa applications.

Provides a backend-agnostic CacheBackendInterface (plus the tag-aware TaggedCacheInterface / TagAwareCacheInterface) and three backends:

  • MemoryBackend — in-process store with a precise dual tag-index; ideal for tests.
  • DatabaseBackend — PDO-backed persistent store (the production backend). Serializes values into a per-bin table; corrupt/unreadable rows are treated as a cache miss, and an optional HMAC integrity key (off by default) makes tampering detectable. There is no filesystem backend.
  • NullBackend — no-op store.

CacheFactory / CacheConfiguration resolve a backend per bin. Cache-tag invalidation runs through CacheTagsInvalidator; the event listeners (EntityCacheInvalidator, ConfigCacheInvalidator, TranslationCacheInvalidator, EntityCacheSubscriber) invalidate tagged entries on entity/config/translation lifecycle events. CacheConfigResolver computes cache-control headers, and ContextResolver / ContextRegistry resolve cache contexts.

Key classes: CacheBackendInterface, TaggedCacheInterface, CacheItem, CacheFactory, CacheConfiguration, MemoryBackend, DatabaseBackend, NullBackend, CacheTagsInvalidator, CacheConfigResolver.
