feat: Implement ability to drop cache keys using combination of OR an…

[KminekMatej]

Extending $cache->clean(); with possibility to search for tags to drop using AND logic

• new feature?
• BC break? no
• doc PR: nette/docs (not yet, but planned)

Usage:
Dropping entities having tags animal and dog and (brown or white). Will not match entity, tagged animal and dog and black.

$cache = new Cache($this->cacheStorage, "animals");
$cache->clean([
    Cache::Tags => (new CacheSelector())->where("animal")->where("dog")->where(["brown", "white"])
]);
//

Standard behaviour stays unchanged.

Documentation planned to create after expected discussion

Have you considered using adminal-dog as tag instead of having tags animal and dog?

[KminekMatej]

@JanTvrdik I did and it works. However this is usable for some simple scenarios like you wrote, but when the logic grows bigger, using this approach makes it way clearer.

In some points, I need to drop all animals, regardless on any other tags they have. In that case, I need to add to newly created dog these tags:

1. Animal
2. Animal-Dog
3. Animal-Dog-Brown

You can imagine that when your orm complexity grows large, this gets a big messy. Way easier solution is then tagging with:

1. Animal
2. Dog
3. Brown

and in different points of application perform drops right the way you want
