Jenkins (or Zuul, or whatever is handling Git submodules) should update submodules recursively by passing the '--recursive' flag to 'git submodule update'.
Is this in regards to https://gerrit.wikimedia.org/r/#/c/48227/? That was because the submodule change had to get merged first. I don't think it's a bug.
In other words, the change to mediawiki/extensions/GuidedTour/guiders had to get merged before the change in mediawiki/extensions/GuidedTour that required it.
It seems the extension are fetched with their submodules. From the merging job https://integration.mediawiki.org/ci/job/mwext-GuidedTour-merge/77/console 10:15:25 stdout: Cloning into 'modules/externals/mediawiki.libs.guiders/mediawiki.libs.guiders.submodule'... 10:15:25 10:15:25 stderr: fatal: reference is not a tree: 7d86ef3ac4896bcae553891d8c2faf02b643320a 10:15:25 Unable to checkout '7d86ef3ac4896bcae553891d8c2faf02b643320a' in submodule path 'modules/externals/mediawiki.libs.guiders/mediawiki.libs.guiders.submodule' Which mean 7d86ef3ac4896bcae553891d8c2faf02b643320a was not in the submodule apparently (aka what Matthew explained just above). For the record, the extension jobs are generated by Jenkins Job Builder. It apply the default settings 'use-zuul-for-mw-ext' which create the git part with submodule default setting (which is to fetch submodules).
