If an update hook has a dependency declared in a hook_update_dependencies implementation and that dependency doesn't exist yet, a notice is emitted when visiting update.php.
Implement hook_update_dependencies:
/**
* Implements hook_update_dependencies().
*/
function some_module_update_dependencies() {
$dependencies = [];
$dependencies['some_module'][9401] = [
'user' => 10000,
];
return $dependencies;
}
user_update_10000 is added in Drupal 10. When visiting update.php on Drupal 10 all is fine, but when visiting it using Drupal 9 the following notice is emitted:
Notice: Undefined index: taxonomy_access_fix_updates
Drupal\system\Controller\DbUpdateController->selection()() (Line: 335)
A real-life example can be seen in
the following failing test run →
of the taxonomy_access_fix module.
Fix the broken code.
Needs work
11.0 🔥
The change is currently missing an automated test that fails when run with the original code, and succeeds when the bug has been fixed.
Thanks for reporting. Can we add a test case showing the issue please
Thanks.
