• Many (core) developers did not notice that the config_prefix of config entities does NOT contain a trailing dot and forgot it when listing/querying for all available config object names within a config-prefix namespace.
  • Omitting the trailing dot can very/too easily lead to false-positives. Essentially a very similar problem space we have with module hook implementation names already; e.g., foo_bar_baz() can be foo's hook implementation of hook_bar_baz(), but also foo_bar's hook implementation of hook_baz().

Proposed solution

  1. No change to existing entity type meta-data/annotations.

  2. Make the entity plugin manager perform this:

    // Ensure that config_prefix ends with a trailing dot.
    if (isset($definition['config_prefix'])) {
      $definition['config_prefix'] = rtrim($definition['config_prefix'], '.') . '.';
  3. Change all callers/actors that operate on config_prefix directly to remove the additional/custom futzing with a trailing dot.

Hrm. Grepping for config_prefix...

1) reveals how utterly apparent the awareness problem of a trailing dot is.

2) reveals that all usages that want to load the actual manifest file would have to strip the trailing dot again.


I did not touch all instances. Left a range of comments instead.
