🐛 | Drupal core | ModuleHandler skips all hook implementations when invoked before the module files have been loaded
🇳🇱Netherlands jsst
For us too, patch #15 brought an end to a long running terror bug, causing spontaneous crashes due to this issue. Our site was running fine for five years, but somewhere during the upgrade to 10.2 the random cache corruption started to hit. Our http middlewares don't do anything special, something in Drupal Core made this bug worse. The bug is hard to debug because it seems to depend on concurrent usage of the site and clearing the cache can fix the bug (after running it up to 10 times) but also cause it.
So we have a major bug that is hard to debug and causes a site to go completely offline, with an unreliable fix (drush cr until it works). Seems to me we should be merging #15 in Drupal 10.2 as soon as possible.
