#31463 closed defect (bug) (fixed)

Avoid reaching inside the object cache object in tests

It'd be really fantastically great if WP_UnitTestCase::flush_cache could keep its hands off my internal properties. :)

Right now, flush_cache reaches into $wp_object_cache and messes with a bunch of internal properties:

$wp_object_cache->group_ops = array();
$wp_object_cache->stats = array();
$wp_object_cache->memcache_debug = array();
$wp_object_cache->cache = array();

If we could just not do that, that'd be greaaaat.

I couldn't find anywhere that was actually setting these properties anyway. I don't know if I'm missing something but I don't see a purpose for these lines. The $wp_object_cache->cache = array(); seems to be redundant as that's what wp_cache_flush does.

@voldemortensen FWIW, those lines are included for external object caches, not the core classes. Those properties, and __remoteset are used by Memcache, but others might use something different (I don't think __remoteset is even used in a published object cache, I think it's only used by the internal one)

See and

I guess we'd have to add a new method/parameter to do this, and even possibly include the back-compat code here.

Moving off of the 4.2 milestone as this is a release-independent change.

In 55741:

Build/Test Tools: Call wp_cache_flush_runtime in WP_UnitTestCase.

In WP_UnitTestCase::flush_cache method, the properties of the global $wp_object_cache object were manaully being reset to flush the cache. The function wp_cache_flush_runtime was added in [52772] and is designed to reset any class properties to default values. Using wp_cache_flush_runtime improve compatibility with third party object caches, as it allows developers to define their own wp_cache_flush_runtime function.

Fixes #31463.
