Calling $migration->getMigrationDependencies() from a field plugin results in an infinate loop

Created on 22 July 2025, about 1 month ago

Problem/Motivation

Calling $migration->getMigrationDependencies() from a field plugin results in an infinite loop. This is because that method calls ::expandPluginIds, which in turn calls ::getDefinitions which in turn calls the node deriver, which in turn calls ::getDerivativeDefinitions calls the field plugin manager, which loops ad nauseam.

Steps to reproduce

See problem statement above.

Proposed resolution

Reverse course on always expanding plugin IDs. If someone needs it, they should have to consciously call for it.

Remaining tasks

🐛 Drupal 7 to Drupal 11 migration runs forever Active complains about this on the contrib project. Given it is breaking contrib, I'm moving this to a major.

For now, I'm going to implement https://git.drupalcode.org/project/paragraphs/-/merge_requests/115/diffs... in the contrib module that this effects. I'm not sure another rewrite off all this when field migrations are about to go away is really desired.
