Verification token does not get deleted on reset

[felixarntz]

Bug Description

When resetting the plugin before a user has received an access token, any other user data that might already be present in the database is not cleared.

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• When resetting the plugin, all Site Kit user data should be cleared, also when the user does not have an access token yet.

Implementation Brief

• In order to determine all the users which need to have their Site Kit data cleared, we need to modify the query to check for any of the meta keys that are set for the user potentially before they have an access token:
  • Verification_Tag::OPTION
  • OAuth_Client::OPTION_PROXY_ACCESS_CODE
  • OAuth_Client::OPTION_ERROR_CODE
• We can do that with a meta_query using OR subqueries.
• This should happen in the Reset class and (although that is not as crucial) also in the Migration_1_0_0 class.

Changelog entry

• Ensure verification tokens and other plugin user data correctly get cleared when resetting the plugin before the user has authenticated.

QA ✅

After clicking reset, the googlesitekit_site_verification_meta user option is wiped from the DB.
