An excessive amount of autoloaded options is a common cause for slow database responses, sometimes caused by very large individual autoloaded options. As it is not mandatory to provide an autoload value when adding an option to the database, it tends to be ignored, which in combination with a default value of "yes" and lack of documentation can lead to the aforementioned problem.
This changeset enhances the option autoloading behavior in several ways:
* Update the function documentation to encourage the use of boolean `true` or `false` to explicitly provide an autoload value for an option.
* Use new string values `on` and `off` for explicitly provided values stored in the database, to distinguish them from `yes` and `no`, since `yes` does not allow determining whether it was set intentionally by the developer or only as a default.
* Effectively deprecate the values `yes` and `no`. They are still supported for backward compatibility, but now discouraged.
* Use `null` as new default autoload value for `add_option()`. If the developer does not provide an explicit value, this will now trigger WordPress logic to determine an autoload value to use:
* If WordPress determines that the option should not be autoloaded, it is stored in the database as `auto-off`. As part of this changeset, the single heuristic introduced for that is to check whether the option size is larger than a threshold of 150k bytes. This threshold is filterable via a new `wp_max_autoloaded_option_size` filter.
* If WordPress determines that the option should be autoloaded, it is stored in the database as `auto-on`. No logic to make such a decision is introduced as part of this changeset, but a new filter `wp_default_autoload_value` can be used to define such heuristics, e.g. by optimization plugins.
* If WordPress cannot determine whether or not to autoload the option, it is stored in the database as `auto`.
* This effectively means that any option without an explicit autoload value provided by the developer will be stored with an autoload value of `auto`, unless the option's size exceeds the aforementioned threshold. Options with a value of `auto` are still autoloaded as of today, most importantly for backward compatibility. A new function `wp_autoload_values_to_autoload()` returns the list of autolaod values that dictate for an option to be autoloaded, and a new filter `wp_autoload_values_to_autoload` can be used to alter that list.
These behavioral changes encourage developers to be more mindful of autoloading, while providing WordPress core and optimization plugins with additional control over heuristics for autoloading options where no explicit autoload value was provided.
At the same time, the changes are fully backward compatible from a functionality perspective, with the only exception being that very large options will now no longer be autoloaded if the developer did not explicitly request for them to be autoloaded. Neither WordPress core nor plugins are able to override an explicitly provided value, which is intentional to continue giving developers full control over their own options.
