Falling back to branch master
Prepared mediawiki/vendor repo with branch master

Should be REL1_25.

mediawiki/core fundraising branches are similar to the wmf branch. So we have no need to use the mediawiki-extensions-* job but should instead use the submodules.

I forgot the fundraising branches are similar to the wmf branches. We should use git submodule update instead of cloning a bunch of extensions.

@hashar: Thanks for noticing this, and for the workaround! In the long run we definitely want the extensions tests to run, I'll see if I can make this change in the CI config.

Ah, another annoying issue is that we currently can't reference anything from DonationInterface/vendor in tests, because the production branch has tests removed and vendor/ as a submodule, and the development branch has no vendor/. CI populates mediawiki-core/vendor with stock wmf deployment libraries, without incorporating extra libraries mentioned in DonationInterface/composer.json.

Seems for dev we will want to run composer to fetch the DonationInterface dependencies.

For production branch, I guess that would need a different job that process submodules.

I am not sure about the testing strategy to be honest :-(
