 In [changeset:"57030" 57030]:
 {{{
 #!CommitTicketReference repository="" revision="57030"
 Options, Meta APIs: Fast follow fixes for option cache priming functions.

 A collection of fixes for `wp_prime_option_caches()`:

 * cache arrays and objects in their serialized form for consistency with
 `get_option()` and `wp_load_alloptions()`
 * prevent repeat database queries for falsey and known non-existent
 options (notoptions)

 Additional tests for `wp_prime_option_caches()` to ensure:

 * additional database queries are not made repriming options (known,
 known-unknown and alloptions)
 * cache is primed consistently
 * `get_option()` returns a consistent value regardless of how it is primed
 * database queries do not contain earlier primed options
 * `get_option` does not prime the cache when testing the cache has been
 successfully primed

 Fixes a test for `wp_prime_option_caches_by_group()` to ensure
 `get_option` does not prime the cache when testing the cache has been
 successfully primed.

 Follow up to [56445],[56990],[57013].
