[Pywikipedia-l] login.py is broken !

[Nicolas Dumazet]

I can't login anymore using login.py on wikimedia sites. This is, I
think, because of the recent changes with Global Auth / SUL.

This is not an immediate issue, because we can actually all use our
bots, given that our cookies dont expire. But with time this is going
to be annoying.

On a timeline aspect, Darkoneko told me that login.py was working
yesterday morning, so this is quite recent.

So far, I can give you an HTTP response on a login (given that the
right password is entered) :

We are given 3 cookies, but we previously expected one more cookie,
frwikiToken, which is not available on the HTTP answer. Previously,
when all the cookies werent sent back, we searched for a captcha in
the page and sent again the post data with the captcha answer to
retrieve the entire cookie.

However, here, there is no page content. The HTTP response is a 302,
page temporarily moved, and the relocaton - from the header - is
http://fr.wikipedia.org/w/index.php?title=Special:Connexion&wpCookieCheck=login

I don't know what is needed here : I tried retrieving that second
page, and unsurprisingly, the HTTP response is a 403 forbidden, likely
because I need to send along some data. The question is : what data
exactly is needed ? Send again the same post data ?

X-vary-options mentions the missing cookie, frwikiToken, do you know
what is that header entry ? Google searches return squid issues (and
funny thing, patches from Tim Starling) : is it relevant here ?
About squids, I consider the cache MISSes as normal, because squids
can't handle login information, and just redirect us to a login
server. Am I right on this one ?


Any help on this is welcome, I failed finding any related mediawiki
documentation.

Most of all, if someone finds a fix, I'd really be interested by the
walkthrough : I'm quite lost with that problem, not exactly knowing
what I should test / try / check. And I need to learn how to do this
