Because of the changes that have been introduced in ResourceLoader in
1.19 (see
https://bugzilla.wikimedia.org/33711 and
https://bugzilla.wikimedia.org/33746 for example), on-wiki gadget users
will begin to see lots of JavaScript errors if we don't act now.
On enwiki.beta (
http://en.wikipedia.beta.wmflabs.org/), I enabled all
the gadgets and then went through the JS errors that popped up to see
what modifications needed to be made to
[[MediaWiki:Gadgets-definition]]. I let [[Wikipedia talk:Gadget]] know
about the needed changes
(
https://en.wikipedia.org/w/index.php?diff=471706835).
We need a lot more of this sort of testing on all the wikis, but I'm
only one person and there are hundreds of wikis. Please have a look at
http://labs.wikimedia.beta.wmflabs.org/wiki/Special:SiteMatrix and find
other wikis to test.
On some wikis (yiwiki.beta, for example), we're going to need to import
the MediaWiki namespace, so if you come across a wiki that is different
than production, let me know or pop into #wikimedia-labs and ping one of
the beta team members there.
Mark.
