Remove 'mediawiki.ui.input' module
Closed, ResolvedPublic
Actions

Description

Background & Goal

Remove all blocking calls to use 'mediawiki.ui.input' module and remove module itself. It has been deprecated since MediaWiki 1.41.

Alongside

Developer notes

  • DiscussionTools and services/mobileapps (1 occurrence) only features parser tests, ignorable.
  • ContentTranslation uses its own derived mw-ui-input CSS and doesn't need attention.
  • Note that a number of outdated extensions and skins –not deployed, that are not set their goal for MediaWiki 1.46 or any of the latest version are not reasonably to be considered here: SemanticMediaWiki "1.43", Wikifab/GroupsPage (more than 10years old in last significant update), Skin:Mask, Skin:Poncho ">= 1.40.0", AWikia/SkinEvelution ">= 1.39.0" – filed https://github.com/AWikia/SkinEvelution/issues/122, femiwiki/FemiwikiSkin, PCGamingWiki/overclocked (not updated in 3 years) are "stuck" on an older MediaWiki version and don't need change.
  • Note that a small number of gadgets and user scripts (less than 50 globally) still make use of the module.

https://global-search.toolforge.org/?q=%22mediawiki.ui.input%27%22&namespaces=&title=

I'm sorry, but this is an insufficient search. Try something closer to this which has many more uses just on English Wikipedia.

Global count is ~200 and that's just the JS.

matmarex added a comment.Mon, May 11, 11:22 PM

If a script uses the mw-ui-input CSS class without loading the mediawiki.ui.input module, then it won't be affected by its removal – it is either already broken, or already works perfectly. We stopped loading the mediawiki.ui.* modules on normal page views years ago.

Just as an example, I picked a script from your search that could be easily tested: User:Enterprisey/cv-revdel.js. Here's how its interface looks today:

image.png (1,263×596 px, 49 KB)

It attempts to style the inputs and buttons using MediaWiki UI, but it never loads the styles, so the classes have no effect. Here's how it would look like if the styles were loaded:

image.png (1,263×596 px, 47 KB)

Many of the scripts that load the mediawiki.ui.input module will also "gracefully degrade" in a similar way. (Some users will probably consider this to be an improvement.)

Only the scripts that load it via mw.loader.using will require changes, and that can be as simple as removing that dependency to unbreak them.

There is however a mistake in that search (I see you got it from the task description): there is a stray apostrophe in the search field, so it only returns single-quoted references to the module, and not double-quoted ones. I am sorry, I overlooked this when reviewing the task, although I am pretty sure I used the correct search when trying to judge the impact of this change. Here's the correct search: https://global-search.toolforge.org/?q="mediawiki.ui.input"&namespaces=2%2C4%2C8&title=(Gadgets-definition|.*\.(js|css|json))

The correct number of results is 123, rather than 58. Many results are copies of the same few scripts, and as I noted above, many won't be too badly affected. I think this is an acceptable removal.
