### Description Fixes https://github.com/apache/dubbo-go/issues/3453 #### 1. RoundRobin selection now atomic under concurrency `cluster/loadbalance/roundrobin/loadbalance.go` The weighted-round-robin select+update sequence was only per-field atomic, so concurrent callers could observe each other's intermediate `currentWeight` and skew distribution. Added a per-key `sync.Mutex` on `cachedInvokers` so the full select+update transaction is serialized per service+method (contention bounded to the same key). ### Tests - `TestRoundRobinByWeightConcurrent` — 50 goroutines × 30 selections, race-clean ### Checklist - [x] I confirm the target branch is `develop` - [x] Code has passed local testing - [x] I have added tests that prove my fix is effective or that my feature works -- This is an automated message from the Apache Git Service.
