In #2233883: Link migration needs to convert source url into the appropriate route format for storage we've complete the config schema for the link field. This has exposed missing test coverage.

It is possible that the "attributes" is dead code... from an IRC chat with @GaborHojtsy

alexpott: what are even link attributes?!
14:36 GaborHojtsy
alexpott: that looks liek some contrib extension point that is not well defined at all
14:36 alexpott
GaborHojtsy: no clue
14:36 GaborHojtsy
// Exposing the attributes array in the widget is left for alternate and more
14:36 GaborHojtsy
// advanced field widgets.
14:36 GaborHojtsy
$element['attributes'] = array(
14:36 GaborHojtsy
alexpott: that is in LinkWidget
14:37 GaborHojtsy
alexpott: but Url::_construct() does not allow for an ‘attributes’ field for Urls… so it may be set but then not actually used here
14:38 GaborHojtsy
alexpott: so its some unclear contrib extension point at best AFAIS
14:38 alexpott
GaborHojtsy: it might well be dead code

There is also a theoretical language key that is not even included here even though theoretically supported on Url.

Additional test coverage is a task. But we might want to remove this key instead, which would also be a task.

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

For some of these values, it would also be super helpful to have a UI for that. In my current case for the fragment: #3516646: Allow entering a fragment attribute

This isn't far off. LinkWidget essentially throws away any value that's stored in it. See #3056652: Link options attributes removed on save. My proposal is to update LinkWidget::massageFormValues() to fix this. I'm not sure this will add all necessary tests for the attributes, so I'm leaving this issue open.

Version: 11.x-dev » main
