- # We do not raise an error if the user doesn't exist. This is due to
- # an unfortunate problem with the "user exists" check in AgenDAV.
- # The AgenDAV "shares" table is not tied directly to a username, so
- # we are forced to use a regexp match to decide what rows to delete
- # from that table. We do so regardless of whether or not the username
- # exists in the "prefs" table, because that table stores only non-
- # default preferences -- not all users' preferences.

- # is usually encoded to "%40". These queries do a regex match on
- # the username after replacing the "%40" with a "@".
- #
- # As a precaution, I haven chosen not to delete based on the
- # "calendar" field here. Nobody should have a calendar named
- # "user%40example.com", but it's not impossible -- and we don't
- # want to delete that calendar when the not-necessarily-related
- # "user@example.com" account is removed. And the usual appearance
- # of the user's email address in the "calendar" field happens when
- # he is also the owner, so the calendar does get deleted in the
- # normal situation.
