📝 Walkthrough

Walkthrough

The PR defers page option queries, memoizes shared page options, resolves callable shortcode options, derives block attributes from defaults, and limits Gutenberg support scripts to block editor screens. SSO tests now restore filters and global state reliably.

Changes

Editor loading optimization

Layer / File(s) Summary
Block attributes from defaults
inc/builders/block-editor/class-block-editor-widget-manager.php, tests/WP_Ultimo/Builders/Block_Editor/Block_Editor_Widget_Manager_Test.php
Block attributes use element defaults and matching field metadata. Field option callbacks are not evaluated. Tests verify the resulting attribute types and values.
Lazy shared page options
inc/functions/pages.php, inc/ui/class-current-site-element.php, inc/ui/class-my-sites-element.php, inc/ui/class-site-actions-element.php, inc/admin-pages/class-shortcodes-admin-page.php, tests/WP_Ultimo/Functions/Pages_Functions_Test.php
wu_get_pages_as_options() memoizes page options by blog and current-page context. The three UI elements use deferred callbacks. Shortcode metadata resolves callable options before reading option keys. Tests cover memoization and context isolation.
Block editor script gating
inc/compat/class-gutenberg-support.php, tests/WP_Ultimo/General_Compat_Test.php
Gutenberg support exits on non-block-editor screens. Tests cover ordinary admin screens and block editor screens.
SSO test isolation
tests/WP_Ultimo/SSO/SSO_Coverage_Test.php, tests/WP_Ultimo/SSO/SSO_Extended_Test.php
SSO tests remove temporary filters, clear request state, restore the current user, restore the Domain Mapping instance, and verify filtered setting values.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to d7ba3

This change defers Gutenberg work and derives block attribute types from PHP defaults, but 0/1 toggle values may change from boolean to integer representations and affect existing blocks or saved content. The PR is otherwise mergeable with explicit owner confirmation of compatibility.

210-234: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep toggle attributes boolean

The previous implementation mapped toggle fields to boolean. The new implementation maps their 0/1 defaults to integer, while ToggleControl reads and writes booleans. This type mismatch can invalidate blocks. Preserve boolean types for toggles without invoking option providers.

123-146: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extend attribute type coverage beyond booleans.

This test correctly locks the no-fields() behavior and the boolean branch. Real element defaults() also use integers and strings (for example columns => 4, site_manage_type => 'default').

Add assertions for integer and string inference so the new type map cannot regress unnoticed.

- Around line 64-82: Update test_gutenberg_support_loads_on_block_editor_screens
to create the standard post screen with set_current_screen('post'), then mark
the retrieved screen as a block editor via is_block_editor(true) before invoking
Gutenberg_Support::add_scripts(). If retaining the compatibility guard,
reference the global \WP_Screen::class so it does not resolve to the namespaced
class.
