kuma's Introduction

kuma

kuma is a multi-platform support network library developed in C++. It implements interfaces for TCP/UDP/Multicast/HTTP/HTTP2/WebSocket/timer that drove by event loop. kuma supports epoll/poll/WSAPoll/IOCP/kqueue/io_uring/select on platform Linux/Windows/OSX/iOS/Android.

Features

Support epoll, poll/WSAPoll, IOCP, kqueue, io_uring and select
Portable/cross platform(linux, windows, macOS, iOS and Android)
Support OpenSSL 1.0 and 1.1
IPv6 support
Flexible/Scalable timer manager
Support HTTP compression gzip and deflate
Support secure HTTP/2 and HTTP/1.1 upgrade to HTTP/2 (rfc7540, rfc7541)
Support WebSocket(rfc6455) and extension permessage_deflate(rfc7692)
Support WebSocket over HTTP/2(rfc8441)
All interface objects, except Timer, are not thread-safe, must run on their EventLoop thread, but close method is thread-safe

Build

define macro KUMA_HAS_OPENSSL to enable openssl

build dependency libkev firstly

python ./third_party/libkev/bld/your_os/build_your_os.py

iOS

open project bld/ios/kuma with xcode and build it

MAC

open project bld/mac/kuma with xcode and build it

Windows

open bld/windows/kuma.sln with VS2017 and build it

python bld/android/build_android_so.py

demo:

open test/android/kmtest in Android Studio

CMake build

CMake is also supported:
python ./bld/your_os/build_your_os.py --msvc vs2017/vs2019/vs2022

OpenSSL

certificates location is by default in /path-to-your-excutable/cert.

copy all CA certificates used to cert/ca.pem
copy your server certificate to cert/server.pem

wss can't receive data

hello Jamol,
I run the test demo as a wss server:
./server wss://0.0.0.0:6086

 and use a webpage to send a wss request:

wss://192.168.31.232:6086
after handshake ,I send a message(binary data),it returned: (Opcode -1).The server log shows:

INFO: [140191080888384] AcceptorBase_2:: onAccept, fd=16, peer_ip=192.168.31.147, peer_port=50079

it can't receive msg from SSL_read function, I anlysysed the ssl_err,it just say,SSL_ERROR_SYSCALL,it's a bottom error. I can't find the answer, hope to get help from you.

you can contact me with email:[email protected]

SSL_ERROR

http is ok, but https always returns -15

wheres http docs?

MBEDTLS support

Have any plan to support mbedtls?
Openssl is too big for embended systems.

Can support Reliable UDP and Reliable MultiCast？

Reliable udp transmission is widely used in real business，There are now many reliable UDP unicast and multicast protocols. as：QUIC，KCP，NORM(Negative-ACKnowledgment Oriented Reliable Multicast)，PGM 。thanks！

how to dump backtrace？

Hi
this is a good project but it is too hard for me, so I want to debug it with backtrace step
by step .
in kmtrace.h I add below:
#define KUMA_DUMPTRACE(x)
do{
std::cout<<getObjKey()<<":: "<<x<<"...\n";
Backtrace();
}while(0)

void DumpBacktrace();

in kmtrace.cpp add：

#if defined(GLIBCXX) && !defined(UCLIBC)
#include <cxxabi.h>
#include <execinfo.h>
#endif

void DumpBacktrace() {
#if defined(GLIBCXX) && !defined(UCLIBC)
void* trace[100];
int size = backtrace(trace, sizeof(trace) / sizeof(trace));
char* symbols = backtrace_symbols(trace, size);
printf("\n==== C stack trace ===============================\n\n");
if (size == 0) {
printf("(empty)\n");
} else if (symbols == NULL) {
printf("(no symbols)\n");
} else {
for (int i = 1; i < size; ++i) {
char mangled[201];
if (sscanf(symbols[i], "%[^(]%[(]%200[^)+]", mangled) == 1) { // NOLINT
printf("%2d: ", i);
int status;
size_t length;
char* demangled = abi::__cxa_demangle(mangled, NULL, &length, &status);
printf("%s\n", demangled != NULL ? demangled : mangled);
free(demangled);
} else {
// If parsing failed, at least print the unparsed symbol.
printf("%s\n", symbols[i]);
}
}
}
free(symbols);
#endif
}

so if I want dump backtrace, i use it , for : KUMA_DUMPTRACE("sendPreface");
I get this result:
==== C stack trace ===============================

why ./server() can not show the function ? even I add -rdynamic g++ param in test/server/MakeFile?
can you tell me?
thanks !

ssl error ？

ws.onError,err=-12

onTimer
ws.onError, err=-12

SSL_ERROR

I have obtained the certificate of www.baidu.com (mv baidu.com.cer ca.pem)
but the error in the figure still appears

buildRequestHeaders didn't make path well.

H2StreamProxy.cpp : buildRequestHeaders()
The git old version discard the path part, so that I get 400 bad request.
------from----------
std::string path = uri_.getPath();
if(!uri_.getQuery().empty()) {
path = "?" + uri_.getQuery();
}
if(!uri_.getFragment().empty()) {
path = "#" + uri_.getFragment();
}
--------to--------
std::string path = uri_.getPath();
if(!uri_.getQuery().empty()) {
path += "?";
path += uri_.getQuery();
}
if(!uri_.getFragment().empty()) {
path += "#";
path += uri_.getFragment();
}

How to get the post param data from http request?

node.js return error "RangeError: Invalid WebSocket frame: MASK must be set"

The proggram runned on ubuntu, and the sever throw error "RangeError: Invalid WebSocket frame: MASK must be set" and exited.

A bug in kuma/src/http/Uri.cpp ?

line 42, Uri::parse function，I used it to parse url such as "ws://192.168.20.105:9326?token=android" , the variable query_ is empty string.

A bug in src/ws/WSHandler.cpp

src/ws/WSHandler.cpp，line 174、199, if len == pos，data[pos++] will be out of bounds , and the variate ctx_.hdr.xpl.xpl16 will be set wrong value.

Support Quic?

Hi,
I love kuma very much.

When do you suppose to support Quic?

Thanks

Can not use in the FreeSwitch Project.

Stable status

Hi,
My question is how stable this library?
With regards

No Luck compiling with OpenSSL

x86 support

How can i compile this project to support android x86 or any other abi for that matter.
I tried generating openssl libs for x86 and put it in vendor folder however it did not work.
It keeps on giving errors like undefined references to few BIO_* and X503_*

it seems that no way to set Http2 connection with timeout

while TcpSocket::Impl::connect has timeout_ms arg,
but TcpConnection didn't pass this arg.

close() outside seems useless when connecting.

    // http is kuma::HttpRequest
    std::function<void()> fReconnect = [&] {
        puts("Reconnect");
        http.close();
        http.sendRequest("GET", "https://xxxxxxxxxxxx/");
        timerReconnect.schedule(1000, Timer::Mode::ONE_SHOT, fReconnect);
    };
    timerReconnect.schedule(1000, Timer::Mode::ONE_SHOT, fReconnect);

I had to insert this code into SocketBase::connect

    if (timeout_ms == 0)
        timeout_ms = 100;

and then it seems better to quick reconnect.
