Function replicationScriptCacheFlush

app/redis-6.2.6/src/replication.c:3097–3101

Empty the script cache. Should be called every time we are no longer sure * that every slave knows about all the scripts in our set, or when the * current AOF "context" is no longer aware of the script. In general we * should flush the cache: * * 1) Every time a new slave reconnects to this master and performs a * full SYNC (PSYNC does not require flushing). * 2) Every time an AOF rewrit

 *    to reclaim otherwise unused memory.
