Bug: Compatibility to wmf/1.43.0-wmf.1

[physikerwelt]

We see the following error

MediaWiki internal error.

on https://staging.mardi4nfdi.org/wiki/Model_for_Electric_Potential_for_Gate_Electrodes_in_a_Quantum_Bus after upgrading to the latest production release. I wonder if this skin is deployed on any wiki that follows the WMF release cycle, as the root cause for the problem might also be somewhere else.

It looks like the Chameleon code is likely not even compatible with the future REL1_42 yet: #422

[physikerwelt]

@malberts, Normally, these updates are easy to fix once you find the correct phabricator ticket, which I did not manage to do in a few minutes.

[physikerwelt]

For this particular problem, it's just this line

chameleon/src/Chameleon.php

Line 34 in 0225fb1

use ResourceLoader;

which has another namespace, but I think the full namespace needs to be added everywhere...

[physikerwelt]

By the way... the phabricator ticket is https://phabricator.wikimedia.org/T166010

@JeroenDeDauw, what do you think?

@JeroenDeDauw, what do you think?

#423

[malberts]

#423 might not be enough to solve the 1.42 compatibility. There are also ResourceLoader namespace changes in the SCSS dependency, and possibly our Bootstrap extension too. I am looking at those.

[malberts]

@physikerwelt Can you try with the latest Chameleon master branch (which is going to be the new major version 5.0.0).

I updated the Bootstrap and SCSS dependencies and CI now passes on MW 1.42 and MW master. However, I have not manually tested either of those unreleased MW versions.

[physikerwelt]

Thank you. This is a great improvement. A quick update from our side:

We updated to the latest master today at 3am.
The good news is, even if the skin is loaded the portal does not crash with a fatal. However, I did not manage so far to activate the skin, as I can not access the skin selection preference page due to a js error

https://staging.mardi4nfdi.org/w/load.php?lang=en&modules=startup&only=scripts&raw=1&safemode=1

does produce an invalid result:

This might be unrealated... however, I just had 20 minutes for this task today and wanted to share the preminar good result with you anyhow.

Thanks @physikerwelt. That ResourceLoaderSkinModule error was indeed caused by Chameleon. I fixed it this morning and now it's loading correctly:

[physikerwelt]

Thank you. Works perfect.
