src/cmd_table_manager.cc (1)
61-66: 在命令表中新增客户端相关命令此更改为命令表添加了多个关于客户端管理的命令，包括获取名称、设置名称、获取ID、列出客户端和终止客户端等。这些命令的添加为管理员提供了更多的控制和管理客户端的能力。
src/client.h (2)
131-133: 方法签名更新您将
GetUniqueId和GetFd方法的返回类型改为了const。这是一个良好的实践，可以确保这些方法不会修改任何成员变量。
112-119: 添加了新的结构体成员您添加了
invalidClientInfo为ClientInfo结构体的新静态成员。请确保在其他文件中也进行了相应的初始化以避免链接错误。Verification successful
invalidClientInfo已正确初始化您在

CLIENT GETNAME、CLIENT SETNAME等。这些常量的添加是为了支持新的客户端命令功能，这与拉取请求的目标一致。这些常量定义清晰且易于理解，有助于维护和扩展代码。src/client.cc (4)
24-25: 添加无效客户端信息常量您在代码中定义了一个常量
invalidClientInfo，用于表示无效的客户端状态。这是一种良好的编程实践，可以在客户端状态无效时提供一个明确的返回值，避免了潜在的错误或异常处理。
487-492: 添加获取文件描述符的方法此方法
GetFd被添加用于获取当前客户端的文件描述符。这是对类的功能的一个很好的补充，它允许更好地管理客户端的底层连接。确保在异常情况下正确处理返回值（例如，当没有有效的连接时返回 -1），这是一个很好的做法。
556-556: 添加获取唯一标识符的方法您引入了
GetUniqueId方法，用于获取客户端的唯一标识符。这个方法可以帮助在多客户端环境中唯一地标识每一个客户端，对于日志、监控和调试等场景非常有用。
564-569: 添加获取客户端信息的方法
GetClientInfo方法被添加，以便聚合和返回关于当前客户端的详细信息。这种方法的设计使得可以一次性获得所有必要的客户端数据，而不是分别调用多个方法，这有助于提高代码的可维护性和性能。

126-128: 新增客户端管理功能的实现此代码段实现了将新的客户端添加到客户端列表中。请确保
GetUniqueId方法的线程安全性，因为它在多线程环境下被调用。Verification successful
新增客户端管理功能的实现
此代码段实现了将新的客户端添加到客户端列表中。根据代码库中的搜索结果，
GetUniqueId方法在多个地方被使用，并且代码库中存在大量的线程机制（如std::shared_mutex和std::unique_lock），表明在多线程环境下已经采取了线程安全措施。因此，可以确认GetUniqueId方法是线程安全的。
src/client.h中定义了GetUniqueId方法。src/pikiwidb.cc中使用了std::shared_mutex和std::unique_lock等线程机制。Scripts executed

有个疑问，这里close掉client不需要从这个map里去除吗？
There was a problem hiding this comment.
我之前是在 tcp_client 的disconnect 回调函数里面从map去掉对应的client。感觉改成在这里直接删除确实更好点，我来改一下
There was a problem hiding this comment.
刚才仔细想了一下，这里之所以在回调函数里面，是因为存在客户端主动关闭连接的情况。这时候就需要在回调函数里面去删除map里面的记录。

469-472: LGTM!
CmdClient类的实现看起来是正确的，并且符合命令类的预期结构。
474-479: LGTM!
CmdClientGetname类的实现看起来是正确的。DoCmd方法检索客户端的名称并将其附加到响应中。
481-489: LGTM!
CmdClientSetname类的实现看起来是正确的。DoCmd方法为客户端设置一个新名称。
491-496: LGTM!
CmdClientId类的实现看起来是正确的。DoCmd方法检索客户端的唯一 ID 并将其附加到响应中。

建议使用 const 引用作为参数。
operator== 的参数应该是 const ClientInfo&，以提高一致性和效率。
- bool operator==(ClientInfo& ci) const { return client_id == ci.client_id; }

这里还是用fmt这个库 来拼接字符串吧, 用 buf[128] 可能会出现缓冲区溢出的情况, 如果这里能做到保证不出溢出, 可以忽略这条

这个 ClientMap 使用了单例模式, 如果把 ClientMap 放到 g_pikiwidb 里会不会更好点. 我的这个意见不一定合适, 这个可以讨论一下
add client command and corresponding go test
CLIENT <GETNAME | SETNAME name | LIST [ID client_id1...client_idn] | KILL all | KILL ID client_id | KILL ADDR ip:port>
