1132-1132: Assess loop condition change inRedis::ZRevrank.The change from
left >= 0toleft > 0affects how the loop iterates over the elements. This modification prevents the loop from considering the last element in the context whereleftrepresents an index. This could be intentional to skip a boundary condition or a specific edge case. However, ensure this change aligns with the intended functionality and does not omit necessary data processing.Verification successful
Assess loop condition change in
Redis::ZRevrank.The change from
left >= 0toleft > 0has been verified. The test cases forZRevrankinsrc/storage/tests/zsets_test.cccover various scenarios and assert correct behavior, indicating that the change does not introduce any issues.
