Deprecation: #85687 - Deprecate RuntimeCacheWriter¶
See Issue #85687
The RuntimeCacheWriter was introduced in TYPO3 9.3 and misused the TYPO3 Caching Framework to provide InMemoryLogging for the AdminPanel. Instead of having a generic LogWriter in the LoggingFramework this belongs to the admin panel scope wise and implementation wise separated from the CachingFramework.
The RuntimeCacheWriter has therefore been deprecated and the AdminPanel will use custom log writers on demand when they will become necessary.
Calling RuntimeCacheWriter will trigger a PHP
Any installation using the RuntimeCacheWriter.
Write your own CacheWriter (see
\TYPO3\CMS\Core\Log\Writer\WriterInterface) or - if you need the exact same
functionality - copy the old RuntimeCacheWriter to your own extension scope and use it.
