Improved: added a service loader which makes sure requests succeed during updates.

[Dan0sz]

Busy sites running OPCache can sometimes trigger uncaught errors due to temporarily missing files during updates and/or fresh installs. So, I added a service loader which properly logs the missing class, but allows the request to properly finish without errors.

📝 Walkthrough

Walkthrough

Plugin now loads services through a class-existence check, conditionally logs missing classes in debug mode, updates service registration paths, and adds integration coverage for missing and available service classes.

Changes

Service loading

Layer / File(s)	Summary
Guarded service loader src/Plugin.php	Adds guarded service instantiation and conditional debug logging for missing classes.
Service wiring and validation src/Plugin.php, tests/integration/PluginTest.php	Routes integrations, provisioning, settings, setup, and registered services through the guarded loader, with tests covering missing and available classes.

Poem

A rabbit checks each class in line,
“If absent, no crash this time!”
Debug logs softly mark the trail,
While present services still prevail.
Hop, hop—safe loading joins the tale.
