Cache Permission Checks 1.5.0

• XF2.3 compatibility update
• Require Redis Cache v2.17.0+

This update vastly improves the speed for changing permissions when a large number of user-groups and nodes exist. Uninstalling is now disruptive, as all permissions need to be rebuilt.

• Require redis cache v2.15.4+
• Reduce memory usage when multiple user's permissions are loaded
• Fix possible race condition when loading permissions from redis
• Dynamically handle any 3rd party XF permission handlers
• CLI command xf-rebuild:sv-cached-permissions can be executed when the add-on is disabled
• Rework XenForo permission handling to on-demand compute permissions instead of computing all possible permissions at once.
  • With large numbers of user-groups and nodes, this can reduce multi-minute permission rebuilds to a few page loads.
  • The xf_permission_cache_content table is no longer populated as this can be incredibly large, and redundant
    For SpaceBattles, the table was ~600mb and was reduce to about ~10mb in redis

• Require Standard Library by Xon v1.18.0+
• If using Redis Cache, recommend Redis Cache v2.13.0+ as it implements saveMultiple correctly.
• Recommend using the free (but not open source) Installer app helper add-on. (Install before upgrading this add-on)
• Significantly reduce memory usage (both in redis & php) for storing many cached permission blobs

• Require XenForo 2.2+
• Require php 7.2+
• Support using SV/InstallerAppHelper to enable this add-on to execute during XF installer app and to prevent this add-on being disabled during add-on upgrades
  • Add-on not yet publicly released
• If installed require the following at the minimum versions:
  • Can Warn Staff v2.2.1+
  • User Essentials v4.2.14+
  • Collaborative Resources v1.3.2+
  • Collaborative Threads v2.7.5+
