Testing is broken because simplesamlphp/composer-module-installer contains a Composer plugin which is blocked

Ran into this problem too over at #3334243-12: CDN 4.x requires PHP >=8.1 but composer does not respect it due to bug in d.o composer facade → . Pity that tweaking drupalci.yml does not work at all per #10, but at least I don't have to experiment with that now thanks to @alexpott in #10 😔

Apparently nobody reported the need for allow-plugins support at: https://www.drupal.org/project/issues/project_issue_file_test?text=allow... → 🤯

Then discovered that #3265092: [META] Define a default .gitlab-ci.yml template that projects can inherit → has been silent for >11 months … so not very hopeful about the GitLab CI approach either. But trying it anyway: #3334243-14: CDN 4.x requires PHP >=8.1 but composer does not respect it due to bug in d.o composer facade → .

FWIW, the drupalspoons template which seems to be pretty much the only thing out there at the moment only just hardcodes a bunch of specific plugins: https://gitlab.com/drupalspoons/composer-plugin/-/raw/master/bin/setup. To customize that, you would need to copy that whole file and add your own?

I think the only reason that "works" for you Wim is that it doesn't include any of the magic that DrupalCI does and does not actually automatically include require-dev dependencies.

Changing to a feature request, as commented in #3265092: [META] Define a default .gitlab-ci.yml template that projects can inherit → , can't we just allow all plugins and move on? The security aspect of that seems irrelevant, as we're running literally any PHP code that's in the repository that's being tested.

If I understand this correctly, we'd need to add the allow-all plugins to https://git.drupalcode.org/project/drupalci_testbot/-/blob/dev/src/Drupa..., before the composer require of the project.

so, run this command there:

composer config allow-plugins true

Created that as a merge request, but the integration doesn't seem to fully work here, so I did that manually, directly in Gitlab and its Web IDE. Obviously entirely untested :)

You an allow whatever plugins you want in your project's composer.json and those will be honored/used by DrupalSpoons. The nones you saw there are auto-allowed so that projects dont *have* to explicitly allow them.

Merged into drupalci_testbot:production - sorry for such a long delay on a straightforward change. Many different priorities swirling around and I simply lost track. Thanks to those who pinged in Slack for an update.

Before marking fixed - would someone please test this on an affected issue and confirm it is resolved?

Thanks for the fix

Note it appears this might have broken testing on PHP 7.4 images, due to a bug in composer, see #3381247: Composer config failure when running functional tests →
