fatal bug: 除零错误

Open AlexStocks opened this issue 8 years ago • 0 comments

在测试nlb/src/api/nlbapi_test.c的时候发现: nlb/src/api/nlbapi.c: calc_success_ratio最后一步req_total结果为0!!!

修改为:

float calc_success_ratio(struct shm_servers *shm_servers, struct server_info *server)
{
    uint32_t req_total;

    req_total = server->failed + server->success;

    if (req_total < shm_servers->shaping_request_min) {
        return 100.0;
    }

    return ((float)server->success) / (req_total == 0 ? 1e-6f : (float)(req_total));
}
