Possible random failure in build tests for cron updates

Hmmm. with 50 test runs the current tests don't fail.

I think lets just keep an on out for more random failures and re-open this issue if needed

I also wonder if when we finally drop support for Drupalci if this will not happen on gitlabci

I think this happening again now that we are using gitlab ci https://git.drupalcode.org/project/automatic_updates/-/jobs/1113256

ok this is very confusing.

1. \Drupal\package_manager\Validator\SupportedReleaseValidator::validate was finding an error because
   

   if ($unknown_packages) {
         $summary = $this->formatPlural(
           count($unknown_packages),
           'Cannot update because the following new or updated Drupal package does not have project information.',
           'Cannot update because the following new or updated Drupal packages do not have project information.',
         );
         $event->addError($unknown_packages, $summary);
       }

   was being hit. but the actually was showing up because $unknown_packages was was just strings so \Drupal\package_manager\ValidationResult::__construct threw an exception because of assert(Inspector::assertAll(fn ($message) => $message instanceof TranslatableMarkup, $messages));

   I fixed this problem by $unknown_packages was an array of translatable objects.

   This would at least let us see what packages where in$unknown_packages. Basically why did randomly 1 out of 20 times did \Drupal\Tests\automatic_updates\Build\CoreUpdateTest::testApi fail.

   which led to.....

2. PHPUnit Test failed to complete; Error: PHPUnit 9.6.18 by Sebastian

       There was 1 failure:
       
       1) Drupal\Tests\automatic_updates\Build\CoreUpdateTest::testApi with data
       set #1 (1)
       Error response: The website encountered an unexpected error. Please try
       again later.Drupal\package_manager\Exception\StageEventException: The
       update cannot proceed because the following Drupal project was unexpectedly
       updated. Only Drupal Core updates are currently supported.
       module 'drupal/automatic_updates' from 3.1.x-dev to 3.0.x-dev.
       Cannot update because the following new or updated Drupal package does not

       (Line: 100)
       Drupal\package_manager_test_api\ApiController->run(Object)

   So now that the translation problem has been solved we can see the actual $unknown_packages that where change 1 in 20 times of running this test.

   So we have 2 validation errors here:
   StagedProjectsValidator:

   Drupal project was unexpectedly
   updated. Only Drupal Core updates are currently supported.
   module 'drupal/automatic_updates' from 3.1.x-dev to 3.0.x-dev.

   and

   \Drupal\package_manager\Validator\SupportedReleaseValidator

   Cannot update because the following new or updated Drupal package does not
   have project information.
   drupal/automatic_updates of type drupal-module

   This is because there is no project key in the info file even though it is a drupal-module since we testing from the git clone.

3. Big question is why did composer downgrade 'drupal/automatic_updates' from 3.1.x-dev to 3.0.x-dev but only 1 out of 20 times the test was run 😱
4. I guess the bigger question is what did the build test start with 3.1.x-dev when we are testing the 3.0.x branch?
