Description
Backport of #7508 to
8.4.Note
Enable multiple slot ranges per shard in SEARCH.CLUSTERSET with robust validation/error reporting, and sort topology shards by node ID for stable ordering; add U16 arg parser and update tests/mocks.
SLOTRANGEentries per shard; ignore replicas; enforce consistentADDR/UNIXADDRacross reappearances.MYIDindex; improved error messages with offsets.MRClusterTopology_SortShards(by nodeid) and replace ad‑hoc sorter; exposeMRClusterNode_Free.AC_GetU16; zero‑init dict entry values inRS_dictAddOrFind.SEARCH.CLUSTERSET: enhanced logging; summarize ranges per shard.CLUSTERSET(multi‑range, errors); extend redismock (last error capture, error reply APIs, argv helpers).Written by Cursor Bugbot for commit d955433.
