liujianhua2016 opened a new issue, #1911:
URL: https://github.com/apache/incubator-brpc/issues/1911
**Describe the bug (描述bug)**
在butil/endpoint.cpp文件 hostname2endpoint函数中，对域名进行提取时，如果域名长度是恰好是63个字符时，
函数会进入这个if判断
if (i == sizeof(buf) - 1) {
return -1;
}
导致函数提前退出返回错误
**To Reproduce (复现方法)**
使用baidu_std协议通过域名方式访问server节点，如果域名长度恰好是63个字符时，会导致channel无法init成功
**Expected behavior (期望行为)**
域名长度不超过63，channel可以init成功
**Versions (各种版本)**
OS: centos7.6
Compiler: gcc-4.8.5
brpc: master
protobuf: baidu_std
**Additional context/screenshots (更多上下文/截图)**
