Wait, what? MediaWiki supports that?! You should not do that.
However, when I log in and look at the special user
page for my own userid, I see that I am in no specific group except for
the implied group of 'autoconfirmed users' and Administrators. There are
checkboxes for the Administrators, Bureaucrats and 'editor' groups, but
none of them are ticked. If I tick a checkbox, and then click save, it
says the setting has been saved but unchecks the checkbox again.
It sounds like UserRights can't reasonably handle groups that are both
implied (e.g. by autopromotion) and actually grant-able to specific users
(where the target user already has implied access?). I'm not entirely
surprised - I'm not sure we officially support that configuration?
Secondly, and more worryingly, is that if I log in
126.96.36.199 IP address, and look at the special user rights page, it
shows everyone as being in the 'Administrators' (sysop) group! If I take
out the autopromote from the LocalSettings file, then no-one (other than
the original account created during installation) is shown as being in
the Administrators group. Very strange.
Okay, matching APCOND_ISIP (and APCOND_IPINRANGE) is based on checking
But take a look at what User::getRequest does:
So it'll determine every user's eligibility for autopromotion... Using the
current requester's IP. Depending on who requests a page (or indeed, from
which IP), the wiki will have different admins. That's ridiculous.
There probably can't be much more useful behaviour from User::getRequest -
a user doesn't have an assigned IP address, and could have made different
sorts of actions from different IPs (log in, edit, etc.) - you wouldn't
want to autopromote any user account that's ever logged in from that
Plymouth University IP, for example. All we can do is look at the current
I wonder why we're not just throwing an exception when code tries to call
User::getRequest for a User other than the one making the request... Maybe
we just shouldn't even have a User::getRequest function at all.
