Walkthrough

Adds a default CORS allowed header of '*' when enabling CORS in DruxtServiceProvider::alter if none are set, and updates the functional test to assert this default.

Changes

Cohort / File(s) Summary
CORS default headers handling
src/DruxtServiceProvider.php
In alter(), when enabling CORS and allowedHeaders is empty, set allowedHeaders to ['*'] before persisting cors.config. Added clarifying comment.
Tests
tests/src/Functional/CorsIntegrationTest.php
Extended testCrossSiteRequestEnabled to assert cors.config.allowedHeaders[0] is '*'.

Poem

A whisk, a hop, a header star,
Now CORS will greet from near and far.
I nibbled code, set “*” to play,
So cross-site calls can find their way.
Thump-thump! The tests all pass—hooray! 🐇✨

22-26: Use empty() and initialize the array to avoid notices; assign instead of append.

  • count($cors_config['allowedHeaders']) can emit a notice if the key is unset/non-array.
  • Prefer initializing the array when empty/undefined and assigning ['*'] rather than appending. This is both clearer and safer.

Apply this diff:

-      // Set allowed headers to '*' by default.
-      if (count($cors_config['allowedHeaders']) === 0) {
-        $cors_config['allowedHeaders'][] = '*';
-      }
+      // Set allowed headers to '*' by default when empty/undefined.
+      if (empty($cors_config['allowedHeaders'])) {
+        $cors_config['allowedHeaders'] = ['*'];
+      }

Please confirm that in all supported environments, cors.config['allowedHeaders'] may be absent or empty (e.g., across Drupal core versions you target), so this guard is appropriate and won’t mask unexpected shapes.

30-30: Make the assertion robust: assert presence rather than array index.

Index-based assertion is brittle. Prefer asserting that '*' is present in the list. Also keep expected argument first when using equals.

Apply this diff:

-    $this->assertEquals($cors_config['allowedHeaders'][0], '*');
+    $this->assertContains('*', $cors_config['allowedHeaders']);

If you intentionally require '*' to be the first element, clarify that contract and ensure the service provider enforces ordering accordingly. Otherwise, the presence check is safer across core defaults.
