Describe the current, buggy behavior

wp doctor check autoload-options-size - 650 kB

SELECT 'Autoload kiB' as name, ROUND(SUM(LENGTH(option_value)) / 1024) as value FROM wp_options WHERE autoload='yes' - 2.4 MB

Difference is in counting _transient_* options.

https://codex.wordpress.org/Function_Reference/set_transient#Notes points out "NB: transients that never expire are autoloaded, whereas transients with an expiration time are not autoloaded. Consider this when adding transients that may not be needed on every page, and thus do not need to be autoloaded, impacting page performance."

Describe what you would expect as the correct outcome

wp doctor check autoload-options-size should count unexpirable transients.

Reading https://github.com/wp-cli/doctor-command/pull/15/files by @danielbachhuber I'm now thinking this may be an issue for wp option command instead. Your thoughts?

[swissspidy]

wp option list ignores transients by default, but they can be included with the --transients argument. It doesn't have an option to include both options and transients though, so the easiest way to solve this is by running two commands here in wp doctor check autoload-options-size:

• wp option list --autoload=on
• wp option list --transients --autoload=one

Then simply add the numbers together.

[danielbachhuber]

Transients are conceptually separate from options, even though they're stored in the same location, so I think this would be better implemented as a new transients-size check.
