Impact

These started to accumulate from urwiki immediately after deploy of 1.38.0-wmf.3 (T281167) to all wikis.

Notes

@Krinkle mentions that gadgets have been refactored recently, and colon in title of gadget on urwiki may be relevant.

I believe to unblock the train we can revert the patch I referenced and re-work it later. Revert will not an introduce a regression of this caliber. But I'll leave the ultimate decision to the patch author and reviewer.

I'll take that arm and raise you my own, it's caused by the other change we made to gadgets this week:

https://www.mediawiki.org/wiki/MediaWiki_1.38/wmf.3/Changelog#Gadgets

change 724740: Make each gadget a separate preference, instead of one huge multiselect (T126962)

Locally reproduced by creating the following:

MediaWIki Gadgets-definition

* foo:quux[ResourceLoader]|quux.js

And then loading Special:Preferences, which fails.

Then in git log, narrowing down with git reset --hard <hash> the last 4 commits until it doesn't fail.

It looks like this change actually didn't make this week's branch cut :)
