Subject: [Wikitech-l] BREAKING CHANGE: action=watch now requires token
(and API requires token and POST)

Hi all,
As of MediaWiki 1.19 the action of watching or unwatching a page
requires a
token [1]. A similar measure was taken during the development of 1.17
for
the markpatrolled action, and the reason is the same: To prevent
third-party sites from executing write actions without the users'
permission.
The ApiWatch module must be posted and given a token. As with other
edittoken-based api actions, the token is salted but stays the same
throughout a session. Scripts may retrieve this token, as usual, through
the ApiQueryInfo (must be logged in, anon users don't have action-watch)
[4]
On a sidenote, recently the the mw.user.tokens resourceloader module [8]
has been created [9]. This, together with the mw.user.options module
introduced in 1.17, gadgets can do advanced actions without polling
the API
for common data. If you script is ran from a wiki, you can get the
tokens
from [5] this Map without an http request to the query info module. An
example has been made in the mediawiki.action.watch.ajax module [6].
This
(un)watches through the API.
The actual change in the WatchAction class was made in r89545 [3].
The ApiWatch module was changed in r88522 [7].
