Change Details

In T177825 it was discovered T177825#3685628 that the maintenance script was run more than once (I vaguely recall this during deployment, but I thought the failure was before any were processed). The script, it appears, was not meant to handle the preference in a mixed-state (i.e. some with usernames, others with user ids). We need three things in order to restore the blocklists: # Recover the preference from the backup for **only** the users who have a `0` (or a series of `0`'s separated by a tab character, there could be more than 2) (i.e. only users who have not already updated their blacklist). # Update the maintenance script to support mixed-state # Apply the data to production and run the updated maintenance script.
