fix microseconds leading zeroes
We have TIMESTAMPTZ field with value: '2023-07-31 16:19:49.91874'
if we map it to trantor::Date class and invoke ::toDbLocalString() it returns '2023-07-31 16:19:49.091874'
The microseconds part is converted incorrectly, because 91874 is not equal to 091874. It should be '2023-07-31 16:19:49.918740'
e.g. https://stackoverflow.com/questions/62937930/postgres-timestamp-with-microseconds
Trantor works with mtls?
Hi,
I'm making some tests with tls connection and i would like to check the performance and verify if this framework works with mutual tls connection. If yes, is there kind of example of code?
I've checked the examples and class TcpClient::enableSSL without success.
Best regards,
Irineu A.
Please use find_package(c-ares)
It will be more consistent way to find the c-ares library.
aarch64: Static_assert fails
Hello,
It compiles fine on x86_64 but fail static_assert on aarch64 (Nvidia Xavier).

I originally thought it was cross-compilation issue but same error happens when compiling directly on Nvidia Xavier board.
使用下面的代码，可以把编译器降低到c++11
//from https://github.com/zhaoyaogit/rpclib
#ifndef MAKE_UNIQUE_HPP
#define MAKE_UNIQUE_HPP
#include

// Default behaviour is to assume C++11, overriding RPCLIB_CXX_STANDARD can use

Missing headers for MinGW in `trantor/utils/AsyncFileLogger.cc`
The file trantor/utils/AsyncFileLogger.cc doesn't build for me when using MSYS2 UCRT64 Clang.
It needs #include <dirent.h> and #include <sys/stat.h>, which are disabled by #ifndef _WIN32.
希望MsgBuffer能提供类似read的write方法
- writeInt32
- writeUInt32
- writeInt16
- writeUInt16
- writeInt8
- writeUInt8
- writeString
- writeByte
- writeBytes

Define Socket Options, instead of writing a method to each one
Description
Hi, would be nice as user point of view, to have the socket options already created, and also, let the user define if needed. So instead of him, know what is the option level, the option name, what is the value and so on ...
We could have something like:
static const Option<std::int32_t> TCP_CORKING;
static const Option<std::int32_t> REUSE_ADDRESS;With this, we could create as many options are there, and, with the benefit of templates compile time code generation, we could write just one setsockopt ...
I was seeing Socket.h, and noticied:
///
/// Enable/disable TCP_NODELAY (disable/enable Nagle's algorithm).
///
void setTcpNoDelay(bool on);
///
/// Enable/disable SO_REUSEADDR
///
void setReuseAddr(bool on);
///
/// Enable/disable SO_REUSEPORT
///
void setReusePort(bool on);
///
/// Enable/disable SO_KEEPALIVE
///
void setKeepAlive(bool on);This works fine, but leads to duplicated code ...
Example
A more detailed example: Socket.h
class Socket
{
public:
template <typename OPTION_TYPE>
struct Option
{
Option(const std::int32_t level, const std::int32_t value)

Note sure if there is a more elegant way ...
And, the usage:
void on_connection(const Socket& client)
{
// Enable TCP CORK
client.set_option(Socket::OptionValue<int32_t>(1, Socket::Option<int32_t>::TCP_CORKING));
// Check if CORK is enabled
cout << "CORK enabled? " << (client.get_option(Socket::Option<int32_t>::TCP_CORKING).value_type ? "true" : "false");
}If you liked, and accept. I would like to implement it!
Thanks!
Issues compiling on Alpine Linux
I had to make a couple of modifications to InetAddress.cc to get trantor to compile on Alpine. Not sure if they are good, since the drogon test suite crashes, but still you may want to take a look at the patch.

assertInLoopThread fails in AresResolver during EventLoopThread destruction
During the destruction of EventLoopThread objects, there is a socket change that gets picked up by AresResolver that fails the assertInLoopThread assertion. Based on my limited understanding of what's happening, I think it should first check if loopValid_ is true before trying to do this. Maybe these lines should be moved into the else if block when loopValid_ is true?

TcpClient 似乎会产生core
当不能链接服务端时候这个函数 Connector::handleError 会被调用， 然后 removeAndResetChannel会被调用， 但是当 TcpClient 析构时候仍旧会调用一次removeAndResetChannel（https://github.com/an-tao/trantor/blob/master/trantor/net/inner/Connector.cc#L38 ） 第二次调用 removeAndResetChannel 时候， channelPtr_ 已经 是 nullptr， 此时会产生core
Crash when exiting program, after exiting event loop via exception
When a controller constructor throws, the event loop appears to exit cleanly after merging PR #224 . However, when the program exits, a fatal error is triggered. Minimal reproduction using Drogon:
Create a Drogon project with a controller:
drogon_ctl create project CrashExample
cd CrashExample/controllers
drogon_ctl create controller ExceptionalController

FATAL no writing but write callback called - TcpConnectionImpl.cc:328
I’m using Drogon’s HttpClient but figured it would make more sense to put this here:
- Using v1.9.1 of Drogon and v1.5.15 of Trantor.
- It’s in an AWS environment that I can’t easily modify or put more verbose logging on. I’ve been unsuccessful in getting any kind of repro in a simpler environment.
- Not sure how to quantify it but I guess pretty infrequent. This env has ~50 TCP connections (as far as HttpClient is concerned) and this gets logged once every ~5,000,000 requests.
- Load on the server - and the client in particular - doesn’t seem to matter. It seems to happen specifically when the network is unstable.
- If a sendRequest() fails with “Timeout” status then there’s no log.
- If a sendRequest() fails with “Network failure” status then this log sometimes accompanies it.
I realize it’s a high ask to fix this under these conditions. I’m more curious if it’s safe to ignore this and if we can downgrade the log severity. I haven’t noticed any kind of memory corruption (though haven't actually had it happen under ASan) or resource exhaustion accompanying it.
(I also noticed this change from a couple hours ago. If that’s likely relevant I’m happy to upgrade and report back when it’s released.)
Cannot send email using SMTPMail plugin
Trantor gives following errors:
20210913 13:58:12.810493 UTC 57380 ERROR Domain validation failed - TcpConnectionImpl.cc:1677
20210913 13:58:12.810536 UTC 57380 ERROR SSL certificate validation failed. - TcpConnectionImpl.cc:1696
I am using letsencrypt certificates and can send email using mail command.
TcpConnectionImpl.cc logs the connections aborted by a client as an unexpected error
TcpConnectionImpl.cc line 482
if (errno == EPIPE || errno == ECONNRESET) // TODO: any others?
{
#ifdef _WIN32
LOG_TRACE << "WSAENOTCONN or WSAECONNRESET, errno="
<< errno;
#else
LOG_TRACE << "EPIPE or ECONNRESET, errno=" << errno;
#endif
return;
}
LOG_SYSERR << "Unexpected error(" << errno << ")";
return;
If client aborted connection (it has a right to do it in any moment, and it is not error in program logic (though error of write function), it should not be logged as unexpected error to attract attention. It should be or silenced, or reported as "Client aborted connection"
Otherwise, it look like error in the program code.
errno == 10053 , WSAECONNABORTED in Windows.
Build error
Call to 'newTLSProvider' is ambiguous
seems that the return type is difference
consider adding TCP_KEEPCNT， TCP_KEEPIDLE，TCP_KEEPINTVL settings from environment variable?
Sometimes we need to set these three values， But we are unable to modify the system configuration， Currently, the trantor does not provide an interface to set it up
if(const char* env_p = std::getenv("TRANTOR_TCP_KEEPCNT")) {
int optval = std::atoi(env_p)
setsockopt(sockfd, SOL_TCP, TCP_KEEPCNT, &optval, optlen);
// setsockopt(sockfd, SOL_TCP, TCP_KEEPIDLE, &optval, optlen);
// setsockopt(sockfd, SOL_TCP, TCP_KEEPINTVL, &optval, optlen);
}
MessageCallback is not work while TcpClient continue sending tcp message
client's ConnectionCallback like this:
client[i]->setSockOptCallback([](int fd) {
int optval = 10;
::setsockopt(fd,
SOL_TCP,
TCP_KEEPCNT,
&optval,
static_cast<socklen_t>(sizeof optval));
::setsockopt(fd,
SOL_TCP,
TCP_KEEPIDLE,
&optval,
static_cast<socklen_t>(sizeof optval));
::setsockopt(fd,
SOL_TCP,
TCP_KEEPINTVL,
&optval,
static_cast<socklen_t>(sizeof optval));
});
client[i]->setConnectionCallback(
[i, &connCount, &str_msg](const TcpConnectionPtr &conn) {
if (conn->connected())
{
LOG_DEBUG << i << " connected!";
while (isContinue) {
std::this_thread::sleep_for(std::chrono::milliseconds(1000));
conn->send(str_msg + '|');
}
}
else
{
LOG_DEBUG << i << " disconnected";
--connCount;
if (connCount == 0)
loop.quit();
}
});
client[i]->setMessageCallback(
[i, &connCount, &reader](const TcpConnectionPtr &conn, MsgBuffer *buf) {
size_t byte_len = buf->readableBytes();
LOG_INFO << "recv " << byte_len << " bytes msg";
std::vector<std::string> msg_array;
splitString(buf->read(byte_len), '|', msg_array);
for (std::string str_msg: msg_array){
Json::Value msg;
if (!reader.parse(str_msg, msg) || !msg.isObject() || !msg.isMember("code") || msg["code"].asInt() == 1) {
// 解析失败
LOG_DEBUG << "parse response error!";
}
else {
LOG_INFO << "parse response success!";
unTotalTimes++;
}
}
});when i run TcpServer and TcpClient，My MessageCallback does't work correctly. Here is the Packet capture。upper side is the TcpServer Console Log。downside is tcpdump info。localhost:53120 is client’s ip and port
TcpClient's Log is Here, which does't Log recv msg.
Make CMAKE_INSTALL_PREFIX configurable

udp support
is there plan to support udp, or popular protocal building upon of udp such as quic?
thanks

Android compatibility
Just a single unused function in trantor/utils/LogStream.h, at line # 83, prevents a build in an Android app project:
void bzero()
{
memset(data_, 0, sizeof(data_));
}If that could be changed to "buffzero" or something like that, not only trantor, but drogon is able to be included in any Android app.
Thanks!
off_t type error on windows
TcpConnectionImpl::sendFile
node->offset_ = static_cast<off_t>(offset);
TcpConnectionImpl::sendFileInLoop
filePtr->offset_ += static_cast<off_t>(nSend);
on windows,off_t is defined with long, not longlong,so big file(more than 4G) will be error offset......
drogon和这个项目能不能建个微信/QQ群？
个人很欣赏作者对muduo的改造，粗略看一下，去掉gcc的方言，去掉boost的各种依赖，重新引入C++17/14的promise的，重写TimerWheel，引入lambda，支持ssl，支持kqueue……，能不能建个微信/QQ群
Some filenames are in the wrong case, preventing Linux->Windows cross-compilation
Windows is not case-sensitive, so spelling includes and libraries in the wrong case doesn't do anything. But it's problematic when one tries to cross-compile from Linux.
I had to fix following includes:
#include <Windows.h>->#include <windows.h>#include <WinSock2.h>->#include <winsock2.h>
And library names for CMake:Rpcrt4->rpcrt4Crypt32->crypt32Secur32->secur32
SO_REUSEPORT is not supported for windows
compiled on windows, but when TcpServer is started, an error (or warning message) prompted indicating that SO_REUSEPORT is not supported.

it seems like that the compile don‘t support unique_ptr?
Is there a way to include the SNI to the ssl?
I was wondering what could be done to support virtual hosts.

Sometimes there is garbled code

`trantor::ConcurrentTaskQueue::runTaskInQueue` hangs indefinitely
On a hosted server with SSL certificates, all functions and API endpoints that relied on trantor::ConcurrentTaskQueue::runTaskInQueue started hanging indefinitely as if the mutex is locked and never unlocked, or something is blocking the queue. runTaskInQueue itself doesn't hang, print statements after it get printed as expected, so it is not an issue of the mutex, it is the task just never executing.
I checked with trantor::ConcurrentTaskQueue::getTaskCount(), and it reported 0 just before the call to runTaskInQueue.
Had to strip all logic that relied on it for the sake of allowing it to work.
Logs were on debug, and may not be of much use.

The server was working fine for the past few days, but an hour ago it started not responding to any API endpoints.
Restarting the host did not help either.
And it serves files just fine.
Things that were changed which could have potentially led to this:
- Set relaunchOnError to true
- Enabled file based logging
How To Exit TcpServer in trantor/trantor/test/KickoffTest.cc ?
In KickoffTest.cc, a Tcpserver Object is created. I wanted to exit this server when there is no client connection. The following is my code:
int main()
{
/**** omit for same code ********/
....
server.setConnectionCallback([&n](const TcpConnectionPtr &connPtr) {
if (connPtr->connected())
{
++n;
if (n % 2 == 0)
{
connPtr->keepAlive();
}
LOG_DEBUG << "New connection";
}
else if (connPtr->disconnected())
{
LOG_DEBUG << "connection disconnected";
/*** Begin: My Added Code****/
--n;
if(n == 0)
{
loop.runInLoop([&server]() {
server.stop();
});
}
/*** End: My Added Code****/
}
});
server.setIoLoopNum(3);
server.start();
loop.loop();
}My Added Code marked the codes that i added. And the server got stucked in line server.stop();.
How to solve it and how to exit a tcp server gracefully?
[sugestion] runAfter, runEvery etc. could be overloaded to use chrono literals
I see in trantor there are lots of methods that take time duration as a parameters. A possible enhancement could be using chrono literals to write 1s, 10min. Example methods were such overloads would be useful are:

What might be the problem?
Edit: The IP 172.104.20.247 has been kept intentionally, it has been trying to connect before with a different IP, and I believe it is the one causing this crash.
Using Botan as TLS provider does not work
I ran it first time and it logged
BotanTLSConnectionImpl does not support sslConfCmds.I disabled TLSv1.3 configuration, and ran it again, it doesn't log anything or respond to a GET request to index.html, it just hangs waiting for a response in the browser.
See this branch.
Edit: Manually entering the address https://localhost:8443 now shows the following in the log and still hangs
20230826 10:32:03.406258 UTC 84510 ERROR Unexpected TLS Exception: TLS record type had unexpected value - BotanTLSProvider.cc:169TLS: FATAL Transport endpoint is not connected (errno=107) sockets::shutdownWrite - Socket.cc:110
Related to this drogon issue, after some debugging it appears to occur on TcpConnectionImpl.cc:427 and Socket.cc:110
Opening and closing connections multiple times within 20 second intervals is the cause.

[FR] 32bit timestamp conversion
We already have trantor::Date::microSecondsSinceEpoch but it will be a pain in ass if I want seconds instead of microseconds.
It will be great if you can implement such function like trantor::Date::secondsSinceEpoch.
PIN thread per CPU for linux similar to seastar

Line 53 in 1af2c68
Wanted to understand if pinning the thread to a CPU id similar to seastar https://github.com/scylladb/seastar/blob/fcd46c13875b04510f8b38d66a82320cc1b393b8/include/seastar/core/posix.hh#L481 would lead to any improvement in performance, have you tried it before ? Is it even a good idea ?
Add and expose enableRead()/disableRead(), startRead()/stopRead() functions
Just tried to use and implement simple tcp proxy server: https://github.com/gonwan/toys/tree/master/webframework-benchmark/trantor-proxy
The trantor library is super fast, and one api issue. For applications like proxy(tunnel, replay etc...), it's better to have the control of socket readability, which is supported by moduo: https://github.com/chenshuo/muduo/blob/a55abc2158d381fced580d7a6c66be06b771c5da/examples/socks4a/tcprelay.cc#L21 . Please add/expose these functions if possible.
Throw on failure instead of exiting
If there are socket errors like if the port fails to bind , could Trantor throw an exception rather than exiting? In this case, the calling application could try again with a different port. Or if the exception isn't caught, then it would fail with a visible error and stack trace rather than just a message in the log.
OpenSSL TLS provider not working correctly
When a HTTPs response with a large content body is sent, then not all bytes will be transferred and the connection will hang indefinitely until it reaches a timeout.
Example request:
curl -X 'GET' -k
'https://192.168.200.232/v2/endpoint'
-H 'accept: application/json'
-H 'Authorization: Basic dGVzdDo=' --trace-time -v
Note: Unnecessary use of -X or --request, GET is already inferred.
