shanhe72101 opened a new issue, #3051:
URL: https://github.com/apache/brpc/issues/3051
**Describe the bug**
apache_brpc/src/bthread/rwlock.cpp
函数rwlock_rdlock_impl
首先会给reader_count加1，超时失败并未恢复计数
因为没有替代方案，严重影响项目进度，跪求大佬们尽快响应，感激不尽！
**To Reproduce**
**Expected behavior**
**Versions**
OS: Ubuntu 24.04.1 LTS
Compiler: gcc 13.3
brpc:1.11.0
protobuf:
**Additional context/screenshots**
为了能够使用std::unique_lock和std::shared_lock管理锁，封装了一个代理类，希望官方能够原生支持，或者推出自己的unique_lock和shared_lock，感谢
class SharedTimedButex {
public:
void lock() {
rwlock.wrlock();
