Redis Cache By Xon 2.18.7

• Fix "CredisException: ERR syntax error ", when a non-integer is passed to \XF::app()->cache->save() without php-redis installed. Known to affect Threadmark's rss caching

• Initial php 8.2 compatibility update

• Fix "Short Thread Count Expiry time" and "Thread Count Expiry time" options where swapped.
• Support caching item-counts in @Bob's Review Management System

• Fix possible redis compatibility issue which may result in empty css being returned instead of a 404

• Fix several php 8.1 compatibility issues with Redis sentinel usage
• Fix bad default port for raw IP when connnecting to multiple redis sentinels

• Fix support for Redis v7+ high-availability using Redis Sentinel
• Add support for redis auth via username/password (vs just password). Requires redis v6+
  PHP:

  $config['cache']['config']['username'] = 'myUsername'; // requires redis 6+, or for cloud redis installations
  $config['cache']['config']['password'] = '....';

• Improve SSL/TLS support, exposing tls/ssl options.
  PHP:

  $config['cache']['config']['server'] = 'ssl://127.0.0.1';
  // See https://www.php.net/manual/en/context.ssl.php for details
  $config['cache']['config']['tlsOptions'] = [
     'SNI_enabled' => true,
  ];

• Fix php 8.1+ error with phpredis + socket connections
• Workaround for php 8.0.17+/8.1.4+ issue when zlib output compression & serving css

• Fix case where cached forum thread counts may be inaccurate due to insufficiently specific cache key

• Update library used to talk to redis to version which is confirmed php 8.1 compatible
• Improve compatibility with 3rd party add-ons with caching applied to user's online list

• Fix email rendering
• Prefix known global functions to avoid a current namespace lookup for the function.
• Work-around for non-desirable caching behaviour when CloudFlare (or similar) is forced to cache css.php output
  • If css.php would return empty output instead return a 404 and cache in redis for at most a second
  • Prevent polluting of caches if the time-stamp is in the future
• Improve XF Cloud support
  • config.php are not required if the stock Redis connector is used.
  • Currently XF Cloud does not use Redis for the main cache which prevents various redis-only add-ons from functioning as expected
