Hi @alberto56,

I've updated the docblock in Drupal\Core\TypedData\ListInterface and Drupal\Core\TypedData\DataDefinitionInterface interfaces with the existing Drupal\Core\TypedData\ListDataDefinitionInterface interface, please check.

Thanks for working on this!

The "proposed resolution" section should be complete and explain the actual change to help the reviewer and committer. Also, this should have some research to support that the change is correct. That is, what is the issue that replaces \Drupal\Core\TypedData\ListDefinitionInterface with something else. Using git blame should make it simple to identify when the changes was made.

Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → .

The MR looks fine to me.

This needs confirmation that the class name change is correct, as stated in #10.

What should happen is to find the commit where the old name was changed and read that commit. This command should help find the commit, git log -S"\Drupal\Core\TypedData\ListDefinitionInterface".

I have restored the 'remaining tasks' to add this point.

I don't find reference to original interface name change. However I can see usage change in issue #2002134 → commit id f6161fad

Yep, it was changed within #2002134

We may see the change here -> https://git.drupalcode.org/project/drupal/-/commit/f6161fadb069ac3cb260c...

Believe question #14 is answered

It's worth noting how this came to be because, well, it's not like this code is AI written to hallucinate interfaces and yet a web search quickly shows this interface only seems to exist in these comments. How odd. Is there perhaps more to this? No: ListDefinitionInterface was added in 2013 in #2047229: Make use of classes for entity field and data definitions → and got renamed to ListDataDefinitionInterface in 2014 in #2002134: Move TypedData metadata introspection from data objects to definition objects → still within the 8.x development cycle.

longwave → closed merge request !11416

Backported down to 10.4.x as a docs-only fix.

Committed and pushed 1935c084986 to 11.x and 8c7ffa560b6 to 11.1.x and 297b980640b to 10.5.x and c5aac1766a7 to 10.4.x. Thanks!
