VipsScaler was used for thumbnailing especially large files, but is no longer used, we moved to Thumbor years ago and it uses vips too: T119184: Thumbor VIPS engine.
Special:VipsTest will disappear from wikis, but it's always explicitly been for testing.

Even with Thumbor, it is/was still being used for some thumbnails (in the current config) - T199938: VipsScaler broken for MediaWiki production (/usr/bin/vips: No such file)
I'm presuming Thumbor will handle them fine...
This should be disproven / confirmed that we have somehow integrated Thumbor in a lambda-like way into MediaWiki where it can process even media files that aren't yet in Swift, as shown to the user during the upload process. I thought this didn't exist, but maybe it does.

Tim recently changed it so MediaWiki no longer thumbnails at all: T260504: Get rid of remaining non-Thumbor MediaWiki image scaling in WMF production. For vips specifically, I looked through exec.log before bringing it up that the only invocations of vips in the past 30 days was from Special:VipsTest.
One this is done should we revert https://gerrit.wikimedia.org/r/c/operations/puppet/+/446640/ if all calls to Vips are going to be done on the Thumbor hosts?
Yes, Reedy filed T290802: Remove libvips-tools from mediawiki appservers (parent task) for it.
Ack, thanks. I recall that task from last year but didn't know it had already been solved (as of Feb 2021). Neat. Consider my concern addressed.

[operations/puppet@production] mediawiki::packages: remove libvips
After VipsScaler has been disabled on all wikis, we started seeing errors fetching thumbnails mimetype which is T290973 . It might be unrelated though.
Because of T291010: MediaWiki refuses to generate thumbnail URLs for large PNGs and TIFFs with "Error creating thumbnail: File with dimensions greater than 100 MP" and T290973: Error: Call to a member function getMimeType() on null we're going to put VipsScaler back for now, even though it wasn't actually shelling out to vips, its hooks were still doing other things that apparently we depend on. Those things need to be fixed but not by just seeing what breaks :/
I'll work on reploying it now.

@Jdforrester-WMF: Per emails from Sep18 and Oct20 and https://www.mediawiki.org/wiki/Bug_management/Assignee_cleanup , I am resetting the assignee of this task because there has not been progress lately (please correct me if I am wrong!). Resetting the assignee avoids the impression that somebody is already working on this task. It also allows others to potentially work towards fixing this task. Please claim this task again when you plan to work on it (via Add Action... → Assign / Claim in the dropdown menu) - it would be welcome. Thanks for your understanding!

This doesn't fail anymore https://test.wikipedia.org/w/index.php?title=User:Legoktm/sandbox&diff=prev&oldid=583704 but maybe because the image is in commons? Anyway, I make sure T291010#7353546 doesn't happen again before moving forward.
I played with it and it's waaay more complicated than it looks. So I much that I gave up. If someone is willing to work on it, I'd be happy to help.
