Thread Synchronization Issues in Logging

Writing logs often happens concurrently in different threads, because when writing logs, new log files are created and old log files are deleted. When thread 1 is creating a new log file, and thread 2 is deleting an old log file at the same time, the program will crash. It is recommended that the author fix this bug.

写日志经常会在不同的线程同时进行，因为在写日志的时候会创建新日志文件和删除旧日志文件，当线程1在创建新日志文件的时候，而线程2同时删除旧日志文件，程序就会崩溃，建议作者修改此bug

不会 notify_all() ？什么 SB 实现。

Which network model does this network library use?

Could you please tell me if this network library is based on an event-driven IO network model similar to muduo, which is based on Reactor?

请问大佬该网络库是那种类似于muduo一样的基于Reactor的基于事件驱动的IO网络模型吗？

About ThreadLoadCounter Statistics Issues

ThreadPool(int num = 1,
               Priority priority = PRIORITY_HIGHEST,
               bool autoRun = true) ;

ThreadPool allows the creation of multiple threads. In ThreadPool::run(), calling startSleep() and sleepWakeUp() performs load statistics. When the number of threads is greater than 1, is the load statistics inaccurate?

ThreadPool(int num = 1, Priority priority = PRIORITY_HIGHEST, bool autoRun = true) ;

ThreadPool允许创建多条线程. 在ThreadPool::run()中调用startSleep()与sleepWakeUp()进行load统计,当线程数大于1时,load统计是否不准确?

Poller thread issues

For example, I have a 4-core machine now, and I start 4 pollers. But every time I get a poller, it's random. How can I ensure that one piece of data is only executed in one poller? If several pollers execute in a loop, will it cause the execution order to be incorrect and lead to data inconsistency?

比如我现在4核的机器，我启动的4个poller，但是我每次getpoller都是随机的，我如何能保证我一个数据只能在一个poller里面执行，如果是几个poller循环执行，会不会导致执行顺序不对导致数据不对的现象？

The _mtx_socket issue in the Socket class

Analyzing the author's network library, I'm confused about the _mtx_socket member of Socket.

In TcpServer.h:

virtual Socket::Ptr onBeforeAcceptConnection(const EventPoller::Ptr &poller){
/**
* 服务器器模型socket是线程安全的，所以为了提高性能，关闭互斥锁
*/
return std::make_shared(poller,false);
}

The server model is thread-safe because socket read/write/timeout/close operations are executed sequentially in one thread. There is no need for mutexes. Therefore, to improve performance, the mutex is closed.

Then why is the non-server model not thread-safe? Specifically,

What is the scenario based on?

正在分析作者的网络库对Socket的成员_mtx_socket很疑惑

         */
        return std::make_shared<Socket>(poller,false);
    }

服务器模型是线程安全的因为socket的读/写/超时/关闭都是在一个线程中顺序执行的不需要互斥量所以为了提高性能关闭互斥锁
那么非服务器模型为什么线程不安全的呢? 具体而言就是

Is the `send` method thread-safe?

Multiple threads call the send method simultaneously, for example:
Thread A: send("hello");
Thread B: send("world");
Thread C: send("china");
It is impossible for the sent order or the received order to be like this: "hechillonaworld".
The send buffer is atomic and indivisible.

多个线程都同时调用了send方法，比如：
Thread A： send("hello");
Thread B: send("world");
Thread C: send("china");
发出去的顺序或者接收到的，不可能存在这种情况吧："hechillonaworld"。
send的buffer是原子性不可分割的。

Does UDP have performance optimizations similar to TcpServer?

It seems that the UDP server is mainly used in RTSP and RTProxy, where performance requirements may not be high.

My situation is that I need a server that mainly accesses through UDP. Is there an optimized solution similar to TcpServer?

There is only one TCP connect interface here:
https://github.com/xiongziliang/ZLToolKit/blob/ed47015f92cc79dfe3344b3666aafb54f1bbc2f4/src/Network/sockutil.h#L62

UDP can also connect:

   If the socket sockfd is of type SOCK_DGRAM, then addr is the address to
   which datagrams are sent by default, and the only  address  from  which
   datagrams  are  received.   If  the  socket  is  of type SOCK_STREAM or
   SOCK_SEQPACKET, this call attempts to make a connection to  the  socket
   that is bound to the address specified by addr.

If we connect both ways, can we achieve a similar effect to TcpServer? If there are any related changes, will you consider merging them into the project?

目前看 udp server 主要看主要是在 rtsp 及 rtpproxy 部分用到, 对性能要求可能不高.

我这边的情况是需要一个及主要通过 udp 接入的服务器, 这边是否有类似 TcpServer 这样的优化方案呢?

这里只有一个 tcp 的 connect 接口
https://github.com/xiongziliang/ZLToolKit/blob/ed47015f92cc79dfe3344b3666aafb54f1bbc2f4/src/Network/sockutil.h#L62

udp 也可以 connect

   If the socket sockfd is of type SOCK_DGRAM, then addr is the address to
   which datagrams are sent by default, and the only  address  from  which
   datagrams  are  received.   If  the  socket  is  of type SOCK_STREAM or
   SOCK_SEQPACKET, this call attempts to make a connection to  the  socket
   that is bound to the address specified by addr.

这样如果双向 connect 一下, 是否可以实现类似 TcpServer 中的效果? 这部分相关的改动如果有的话, 是否会考虑合到项目中?

In the logger, due to time zone issues, today's logs may be written to yesterday's file.

Issue:

The logger, due to time zone issues, may write today's logs to yesterday's file.

Branch

master

Platform

windows

Reason:

https://github.com/xia-chu/ZLToolKit/blob/master/src/Util/logger.cpp#L406
auto day = getDay(ctx->_tv.tv_sec); uses UTC time here.

This leads to the subsequent judgment of if (day != _last_day) in the +8 time zone, writing the log file to the previous day's time.

For example, today is 20200804, in Beijing time 20200804, 00-08h time, all belong to 20200803 UTC time.

This leads to logs from 00-08h Beijing time being written to the 2020-08-03.log file.

问题：

logger中，因为时区问题，会导致今天的日志，写在昨天的文件中。

windows

原因：

https://github.com/xia-chu/ZLToolKit/blob/master/src/Util/logger.cpp#L406
auto day = getDay(ctx->_tv.tv_sec); 这里使用的是UTC时间。

导致后续的判断if (day != _last_day) 在 +8时区的时间内，将日志文件写入前一天时间。

比如今天20200804，在北京时间 20200804，00-08h时间内，都属于20200803的UTC时间。

导致北京时间00-08h的日志，写入了2020-08-03.log 文件中。

How to build a high-performance media forwarding server using ZLToolKit

Background Requirements:

The application scenario is similar to an interactive chat live room, where there may be 1-8 guests speaking (video) simultaneously, and n viewers. The server forwards the UDP media data packets uploaded by the guests to the rest of the people in the room.

There is also some simple signaling, such as entering the room, leaving the room, taking the guest seat, leaving the guest seat (becoming a viewer), etc., which we plan to use TCP for.

Rooms are independent of each other, and one server needs to support many rooms at the same time, so the performance requirements for UDP will be high, while TCP is only for signaling and long connection maintenance. The UDP media data packet header will contain the room number and user uid.

The following are the questions:

Can we refer to test_udpSock.cpp for UDP usage? Are there any other things to note about the use of zltoolkit for our scenario, such as avoiding memory copying?
To forward a packet to other people in the room, do we need to maintain a UDP address list of all people in the room and then send it by iterating through it? Does zltoolkit have any other more advanced and efficient methods?
Regarding the room data structure lookup problem, we currently plan to use a UDP port for listening, and the UDP data packet header will carry the room number. We will parse the header to get the room number and then use a map to find the data structure of this room. Another way is to use a UDP port for listening for each room, so that the data received by this UDP port is naturally for this room, avoiding the need for us to use a map to find the room. Which of these two methods will perform better when the number of rooms is large?

背景需求：
应用场景类似互动聊天直播室，可能有1-8个同时说话（视频）的嘉宾，还有n个观众。服务器将嘉宾上传的udp媒体数据包转发给房间其余人。
还有一点简单信令，比如进房间，离开房间，上嘉宾位，离开嘉宾位（变成观众）等，这部分打算用TCP做。
房间之间是相互独立的，一个服务器需要同时支持很多个房间，所以对UDP的性能要求会高，tcp只是信令以及长连接维持。UDP媒体数据包头会包含房间号和用户uid。
问题如下：
1、UDP的使用参考test_udpSock.cpp即可吗，对于我们这种场景需求，zltoolkit的使用上有没什么其他的注意，比如避免内存拷贝等事项？
2、将一个包转发给房间其他人，是自己维护一个房间所有人的udp地址列表，然后遍历发送吗，zltoolkit有没什么其他更高端高效率的办法？
3、关于房间数据结构的查找问题，目前是打算用一个udp端口进行监听，udp数据包头带上房间号，解析包头得到房间号，然后通过map查找到这个房间的数据结构；另外一种方式是，一个房间使用一个udp端口进行监听，这样这个udp端口收到的数据天然就是这个房间的，避免了我们使用map查找房间。请问这两种方式，哪种房间数量多了性能会好些呢？

Regarding the issue of using EventPollerPool::Instance().getPoller()->doDelayTask() and EventPollerPool::Instance().getPoller()->async() for the heartbeat thread

Now we need to implement an http short link heartbeat interface,

Method 1: Failed

url.append("/acd/api/v1/0/agent/heartbeat");
weak_ptr<WebClient> weakSelf = dynamic_pointer_cast<WebClient>(_client);
EventPollerPool::Instance().getPoller()->async([weakSelf, url]() {
    while (true) {
        sleep(10);
        auto strongSelf=weakSelf.lock();
        if(strongSelf){
            strongSelf->heartbeat(str);
        }
    }
}, true);

Method 2: Failed

EventPollerPool::Instance().getPoller()->doDelayTask(10 * 1000, [weakSelf, url]() {
                auto strongSelf=weakSelf.lock();
                if(strongSelf){
                    strongSelf->heartbeat(str);
                }
                sleep(10);
                return true;
            });

This is the implementation of heartbeat()

void WebClient::heartbeat(const string &url){
    //TraceL << url;
    _heartbeatPost.reset(new HttpRequester);
    _heartbeatPost->setMethod("POST");
    //设置http请求头
    _heartbeatPost->addHeader("Content-Type", "application/json");
    //设置POST参数列表
    Value val;
    val["groupId"] = _groupId;
    val["agentId"] = _agentId;
    _heartbeatPost->setBody(val.toStyledString());
    //InfoL << val.toStyledString();
    //开启请求
    _heartbeatPost->startRequester(url,//url地址
                                   [](const SockException &ex,                          //网络相关的失败信息，如果为空就代表成功
                                      const string &status,                             //http回复的状态码，比如说200/404
                                      const HttpClient::HttpHeader &header,             //http回复头
                                      const string &strRecvBody) {                       //http回复body
                                       //DebugL << "=====================HttpRequester POST==========================";
                                       if (ex) {
                                           //网络相关的错误
                                           WarnL << "heartbeat network err:" << ex.getErrCode() << " " << ex.what();
                                       } else {
                                           TraceL << "heartbeat body:" << strRecvBody;
                                       }
                                   });
}

_heartbeatPost applies for a global variable, but the http package cannot be sent out.
The current method is to apply for a thread and put it in to implement it, but this way of writing is too ugly. Is there any good way to use EventPollerPool::Instance().getPoller() to send the heartbeat request of http?

现在要实现一个http短链接心跳接口,

方法1:失败

url.append("/acd/api/v1/0/agent/heartbeat");
weak_ptr<WebClient> weakSelf = dynamic_pointer_cast<WebClient>(_client);
EventPollerPool::Instance().getPoller()->async([weakSelf, url]() {
    while (true) {
        sleep(10);
        auto strongSelf=weakSelf.lock();
        if(strongSelf){
            strongSelf->heartbeat(str);
        }
    }
}, true);

方法2:失败

EventPollerPool::Instance().getPoller()->doDelayTask(10 * 1000, [weakSelf, url]() {
                auto strongSelf=weakSelf.lock();
                if(strongSelf){
                    strongSelf->heartbeat(str);
                }
                sleep(10);
                return true;
            });

这是heartbeat()的实现方法

void WebClient::heartbeat(const string &url){
    //TraceL << url;
    _heartbeatPost.reset(new HttpRequester);
    _heartbeatPost->setMethod("POST");
    //设置http请求头
    _heartbeatPost->addHeader("Content-Type", "application/json");
    //设置POST参数列表
    Value val;
    val["groupId"] = _groupId;
    val["agentId"] = _agentId;
    _heartbeatPost->setBody(val.toStyledString());
    //InfoL << val.toStyledString();
    //开启请求
    _heartbeatPost->startRequester(url,//url地址
                                   [](const SockException &ex,                          //网络相关的失败信息，如果为空就代表成功
                                      const string &status,                             //http回复的状态码，比如说200/404
                                      const HttpClient::HttpHeader &header,             //http回复头
                                      const string &strRecvBody) {                       //http回复body
                                       //DebugL << "=====================HttpRequester POST==========================";
                                       if (ex) {
                                           //网络相关的错误
                                           WarnL << "heartbeat network err:" << ex.getErrCode() << " " << ex.what();
                                       } else {
                                           TraceL << "heartbeat body:" << strRecvBody;
                                       }
                                   });
}

_heartbeatPost申请的是全局变量,但是http包都发不出去.
现在用的方法是申请一个thread,放进去实现,但是这样写太难看了,请问有什么好方法用EventPollerPool::Instance().getPoller()发http的心跳请求,

MSVC-CI Build Failure

From the compilation log, it seems that the compiler used is not MSVC:

https://github.com/ZLMediaKit/ZLToolKit/runs/3926875128#step:3:138

The error message is also inconsistent when compiling locally using MSVC (only a warning about duplicate zltoolkit.lib for dynamic and static libraries is shown). After modification, there are warnings, but it can be compiled normally.

从编译日志看，使用的不是 MSVC 编译器：

https://github.com/ZLMediaKit/ZLToolKit/runs/3926875128#step:3:138

本地使用 MSVC 编译时错误信息也不一致（只提示了个动静态库的目标有重复 zltoolkit.lib），修改后虽有警告，但可以正常编译。

Continuous reading will blow up the memory.

When a connection comes in at a very high speed, exceeding the actual processing speed. For example, a server receives an uploaded file. The client uploads the file at a speed of 1G, but the server can only write the file at a speed of 100M per second. In this case, the server will continuously read through epoll, eventually overwhelming the memory.

When the server finds that its cached memory has exceeded a certain threshold, it cannot continue to read until EAGAIN. If it is EDGE-triggered, it has to read again after consuming the cached memory. If it is LEVEL-triggered, it has to call epoll_ctl to delete this fd and then add this fd again after consuming the cached memory.

When the server stops reading, the TCP protocol stack will reduce the TCP wnd, thereby suppressing the sending speed of the sender.

It seems that your library does not have this logic.

当一个连接来的速度很快，多到超过实际处理速度。比如一个server接受上传文件。客户端以1G的速度上传文件，但是该server只能以每秒100M的速度写文件。这种情况下，server会持续的通过epoll读，最终撑爆内存。
当server发现自己缓存的内存已经超过一定阈值，它不能持续read直到EAGAIN。如果是EDGE触发，它得在自己消费完了缓存的内存之后再read，如果是LEVEL触发，它得调用epoll_ctl删除这个fd，并且在自己消费完了缓存的内存之后再加入这个fd。
当server不再read时，tcp协议栈会降低tcp wnd，从而抑制发送方的发送速度。

你这个库里似乎并没有这个逻辑。

New multiple tcpclient send message packet loss problem

I created some tcp clients to send messages to the tcpehcosession of this demo, and then the server returns the messages, but I found that the messages received each time are missing. Through network card packet capture, the messages are returned to the client, but I don't know why they didn't come up. In addition, when I control+c tcpehcosession, the client feels that the lost messages are all coming up at this time. Please help me take a look.

Attached is the client code, tcpechosession is only responsible for returning messages, doing nothing

int main() {
    // Set up the logging system
    Logger::Instance().add(std::make_shared<ConsoleChannel>());
	Logger::Instance().add(std::make_shared<FileChannel>());
    Logger::Instance().setWriter(std::make_shared<AsyncLogWriter>());
	for (int i = 0; i < 200; i++)
	{
		TestClient::Ptr client(new TestClient());//Must use smart pointers
		client->startConnect("192.168.1.189", 40996);//Connect to the server
		testmap.emplace(i, client);
	}
	sleep(30);
	for (auto it = testmap.begin(); it != testmap.end(); it++)
	{
		it->second->send("hhhhhhhhhhhhhhhhhhhhhhhhhhhhhh");

我新建了个一些tcpclient 向这个demo的tcpehcosession 发送消息，然后服务器在将消息返回，但是我发现每次收到的消息都少，通过网卡抓包消息是回到了client的不知道什么原因没上来，另外这个时候我control+c tcpehcosession，这面客户端收感觉丢的消息这个时候就都上来了，请帮我看看

附上client的代码 tcpechosession 就负责回消息，啥都不干

int main() {
// 设置日志系统
Logger::Instance().add(std::make_shared());
Logger::Instance().add(std::make_shared());
Logger::Instance().setWriter(std::make_shared());
for (int i = 0; i < 200; i++)
{
TestClient::Ptr client(new TestClient());//必须使用智能指针
client->startConnect("192.168.1.189", 40996);//连接服务器
testmap.emplace(i, client);
}
sleep(30);
for (auto it = testmap.begin(); it != testmap.end(); it++)
{
it->second->send("hhhhhhhhhhhhhhhhhhhhhhhhhhhhhh");
}

Discovering significant network congestion using TcpClient and TcpServer

When using TcpClient and TcpServer, I found a lot of TCP Out-of-Order, TCP ACKed unseen segment, Tcp dup ack packets, even when testing on a local area network.
Is this normal? Do you have any good methods for handling TCP network congestion and out-of-order issues?

在用tcpclient和TcpServer的时候发现用大量TCP Out-of-Order,TCP ACKed unseen segment,Tcp dup ack包,还是在局域网情况下测试
请问这正常吗?您对TCP的网络拥塞,乱序问题处理有什么好方法?

是否借鉴至muduo网络库？看着有点像，不知是否有压力测试

Hello, can the socket add support for the reconnect mechanism?

Blogger, the TCP socket used in the project often needs a reconnect mechanism. Can you add a configurable reconnect mechanism to the socket?

博主，项目中用到的tcp socket经常需要用到重连机制，能否在socket中添加个可配置的重连机制

Please advise on solutions for handling TCP packet fragmentation and packet sticking.

I carefully reviewed the code in your streaming server's HTTP regarding TCP packet merging, but despite my limited knowledge, I still don't understand it very well. I hope the author can explain the general idea of TCP handling packet splitting and merging. I am currently implementing a large file transmission based on ZLToolKit, and I am encountering packet splitting and merging issues.

In addition, I need to implement HTTP file upload now. Do you have a ready-made implementation in your HTTP? Or could you tell me a solution? Thank you very much.

我仔细看了您流媒体服务器中HTTP中关于TCP合包的代码,但是无论才疏学浅,没有很明白,希望作者可以大概讲解下TCP处理拆包粘包的思路,现在基于ZLToolKit要实现一个大文件收发,出现拆包粘包问题.
另外我现在需要实现http上传文件,您的http里面有实现好的吗?或者告诉我一个解决思路,非常感谢

Receiving Long String Issue

When transferring the base64 string converted from the image using the test example tcp client and echo server, the string received by the server always loses a large part of the string.

When printing the length of buf->data() in the above, it is found that it is inconsistent with the client's sending, and it is much smaller.

Thank you very much for your work,

在用测试例子tcp client和echo server传输由图片转成的base64字符串时，服务器端接收的字符串总是丢失一大段字符串

在上面的里打印buf->data()的长度发现与client发送的不一致，小了很多

非常感谢大佬的作品，

_sessionMap consistency issues?

void onManagerSession() {
for (auto &pr : _sessionMap) {
weak_ptr weakSession = pr.second->session();
pr.second->session()->async(weakSession {
auto strongSession=weakSession.lock();
if(!strongSession) {
return;
}
strongSession->onManager();
}, false);
}
}

I'm wondering, when processing this session map, you're iterating through it without any locks. What happens if the map is added to or deleted from while the session is being iterated through? How is consistency maintained? I'm not quite sure.

void onManagerSession() {
for (auto &pr : _sessionMap) {
weak_ptr weakSession = pr.second->session();
pr.second->session()->async(weakSession {
auto strongSession=weakSession.lock();
if(!strongSession) {
return;
}
strongSession->onManager();
}, false);
}
}

请问在处理这个sessionmap的时候我卡你这个时候遍历还是这个seessionmap的添加删除都没用锁，如果这个seesion遍历的过程中，map被添加或者删除了怎么办，这个是怎么保持一致性的？每太搞明白
