See https://meta.trac.wordpress.org/ticket/8331.

This temporarily disables the Photon screenshot srcset because transformed variants can lose the revision and serve stale images. The revision-aware ps.w.org src and lightbox source remain unchanged, and resource hints now point to ps.w.org.

A focused regression test confirms that no Photon candidates are emitted.

Tested

  • Focused PHPUnit, 1 test and 3 assertions
  • Full Plugin Directory PHPUnit, 334 tests and 939 assertions
  • PHP syntax, PHPCS, and git diff --check
  • Full local wporg-plugins-2024 theme
  • Gallery and lightbox for the known cases, including Open, Next, Previous, and Close

Summary by CodeRabbit

  • Bug Fixes

    • Plugin screenshots now load directly from ps.w.org without Photon resizing URLs.
    • Screenshot markup no longer includes Photon-generated srcset candidates, preserving revision-aware image sources.
    • Lightbox behavior and metadata now support restoring the original lossless image and dimensions.
  • Tests

    • Added coverage to verify direct screenshot sources and the absence of Photon URLs and srcset attributes.

📝 Walkthrough

Walkthrough

The screenshot shortcode now preconnects to ps.w.org, documents lossless lightbox sources, and disables Photon-generated srcset candidates. PHPUnit coverage verifies direct revisioned sources and excludes Photon URLs.

photon_srcset() returns an empty fragment. Tests verify direct revisioned sources and exclude Photon URLs. The production fixture defines the production environment type.

Merge Risk: 🔵 Low · up to 4676f

The production change is narrowly scoped, but the added regression test uses a PHPUnit attribute unsupported by the repository’s locked test version. The PR is otherwise mergeable with explicit owner awareness or a follow-up to remove that attribute and keep CI reliable.

🌐 Web query:

PHPUnit 9.6 source PHPUnit\Framework\Attributes\Group PHPUnit 10 attributes introduced

💡 Result:

PHPUnit attributes (found in the PHPUnit\Framework\Attributes namespace) were introduced in PHPUnit 10 [1][2][3]. They were implemented to provide a modern, PHP 8-native way to define metadata for test classes and methods, serving as an alternative to the older "annotation" style comments (e.g., @group, @covers) [1][4]. PHPUnit 10 and 11 still support both attributes and annotations, though they prioritize attributes when both are present [1][5]. PHPUnit 9.6 does not support these attributes [5]. If you are using PHPUnit 9.6, you must continue using annotation-based metadata in your docblocks [5]. To use attributes, you must upgrade your project to at least PHPUnit 10 [1][5].

Citations:


Remove the unsupported PHPUnit attribute.

The repository locks PHPUnit at 9.6.34, which does not support PHPUnit\Framework\Attributes\Group. The unit-test job uses PHP 8.4, so the PHP 7 parse failure does not apply. Retain @group shortcodes and remove the attribute import and declaration.
