zjncs opened a new pull request, #11146: URL: https://github.com/apache/rocketmq/pull/11146
### Motivation `LatencyFaultToleranceImpl.detectByOneRound` only flipped `FaultItem.reachableFlag` from false to true. Once a broker had been marked reachable, a failing service detector was ignored, so `MQFaultStrategy`'s reachable filter kept selecting a broker that had gone down until a real send happened to fail against it. ### Modifications Reset the flag symmetrically when the detector reports the broker unreachable, so the next broker-selection round sees the failure. ### Verification Fail-before (new test, run against the unpatched code): ``` Tests run: 3, Failures: 1, Errors: 0, Skipped: 1 -- LatencyFaultToleranceImplTest#testDetectByOneRoundClearsReachableFlagWhenDetectFails ``` Pass-after: ``` Tests run: 3, Failures: 0, Errors: 0, Skipped: 1 -- LatencyFaultToleranceImplTest ``` -- This is an automated message from the Apache Git Service.
