mediawiki-1.25 API incompatibility

[GreyCat]

I have a mediawiki-gateway based bot that I'd like to run on http://ru.wikipedia.org/ - last time I tried it on about ~2013-12, and it was ok back then, but nowadays I always get the following error:

D, [2014-10-09T08:05:41.453869 #30170] DEBUG -- : GET:

`warning': API error: code 'warning', info 'API warning: The intoken
parameter has been deprecated.' (MediaWiki::APIError)

Basically, it seems that mediawiki-gateway tries to use
action=query&prop=info&intoken=edit stuff, which seems to be
deprecated now:

* prop=info (in) *
  Get basic page information such as namespace, title, last touched date, ...
  https://www.mediawiki.org/wiki/API:Properties#info_.2F_in
[...]
  intoken             - DEPRECATED! Request a token to perform a data-modifying action on a page

It's probably a fairly vital issue, as it makes mediawiki-gateway totally unusable in current Wikipedia's installation environments, at least out of the box.

As far as I understand, it's not necessary to request a token, it would be given out automatically anyway in modern Mediawiki installations - probably this could be simply fixed by removing intoken= setting.

@blackwinter suggested to try ignoring warnings by :ignorewarnings => true in MediaWiki::Gateway.new - I confirm that it works around the issue.

Thanks for filing this issue.

For the record: The MediaWiki version used by Wikipedia (currently 1.25wmf1) is bleeding edge and not publicly released yet. The underlying change, however, has even greater ramifications (wikimedia/mediawiki@fdddf94) and will be released in 1.24, scheduled for next month.

Thanks for checking the Mediawiki version history for me. Wow, I never thought that Wikipedia devops are so bold to live off the bleeding edge in production %)

For better or worse, MediaWiki is Wikipedia, and they've been running those unreleased "wmf" versions for years.

Related to #76.

Is it still necessary to use this workaround?

Here's another warning from MW 1.25, raised by MediaWiki::Gateway::Users#options.

MediaWiki::APIError: API error: code 'warning', info 'API warning: action=tokens has been deprecated. Please use action=query&meta=tokens instead.'

[jpatokal]

This is not going to get fixed unless somebody sends in a pull request.

Also, given that WMF has now released an "official" client at https://github.com/wikimedia/mediawiki-ruby-api, I will likely be deprecating this library entirely soon.

Makes sense, thanks.
