cppserver's Issues

error compiling library on windows 10 using Mingw32 7.3.0 comes with QT 5.13.2

Hi,

I got this error when I tried to compile the library I follow the steps exactly, i use windows 10, compiler MinGW 32 7.3.0

Cannot build on raspberry / UbuntuServer64

While trying to compile on a tiny-but-nice Raspi3, with Ubuntu-server 64bits installed, I get stuck on this compilation:

/home/XXXX/CppServer/modules/CppCommon/source/time/timestamp.cpp: In static member function ‘static uint64_t CppCommon::Timestamp::rdts()’:
/home/XXXX/CppServer/modules/CppCommon/source/time/timestamp.cpp:218:1: error: no return statement in function returning non-void [-Werror=return-type]
}
^

Looking in source code, I can see that:

uint64_t Timestamp::rdts()
{
#if defined(_MSC_VER)
return __rdtsc();
#elif defined(i386)
uint64_t x;
asm volatile (".byte 0x0f, 0x31" : "=A" (x));
return x;
#elif defined(x86_64)
unsigned hi, lo;
asm volatile ("rdtsc" : "=a"(lo), "=d"(hi));
return ((uint64_t)lo) | (((uint64_t)hi) << 32);
#endif
}

As you can see, all defines concern other platforms, so Linux compilation leads to an empty function, which obviously is not right.

I am very suprised, as I already compiled successfully CppServer on my station which is on Ubuntu (Mate).

Here is the ouput beginning of ./unix.sh command (on the faulty Raspi):

As you can see from the output I tried installing Win64 OpenSSL 1.1.1 g from https://slproweb.com/products/Win32OpenSSL.html, sadly that didn't help.
The libcrypto.lib is present in the folder CppServer\modules\OpenSSL\VS\lib\libcrypto.lib, so I think there were no problems with gil (I ran gil update on a clean repo in admin mode).

What am I missing here?

performances

Hello,

I just looked over your repo and it's pretty amazing. Congrats ! All interfaces looks pretty nice and self explanatory.

What I'm wonder it's the performance of this servers from a memory usage and requests/second they can serve point of view.

Looking to your results and on what machine you run the tests I see the HTTP/HTTPS server performances being very poor. Have you compared your results with other solutions ?

For example for websocket have you compared the HTTP and websocket performances with https://github.com/uNetworking/uWebSockets which seems a strong candidate ?

Kind regards,
Silviu

size_t, 32 or 64 bits

Observation,
Looking at the code ws.cpp (and other ones). The "size_t" used all over. I guess the assumption is, the compiler will be 32 or 64 environment.

ws.h
size_t _ws_payload_size{0};
if used in 32 bit environment will not work as intended and will have side effects.

payload = (((size_t)_ws_receive_buffer[2] << 56) | ((size_t)_ws_receive_buffer[3] << 48) | ((size_t)_ws_receive_buffer[4] << 40) | ((size_t)_ws_receive_buffer[5] << 32) | ((size_t)_ws_receive_buffer[6] << 24) | ((size_t)_ws_receive_buffer[7] << 16) | ((size_t)_ws_receive_buffer[8] << 8) | ((size_t)_ws_receive_buffer[9] << 0));
_ws_header_size = 10 + (mask ? 4 : 0);
_ws_payload_size = payload;

It is preferable to explicitly define the "payload" to be "unsigned int 64 bit", as protocol call for.

Can you recommend a technique for deferring a response to another thread?

I'm wondering if you could suggest a strategy to defer a response to another thread. Consider where a response is expensive and needs to be computed. I don't want to block the service threads. Since the onReceivedRequest is a method of HttpSession I can't take a reference to its shared_ptr and ensure it's continued existence if the client closes the other end and the session is disconnected.

I've worked around that by making a subclass of HttpSession that contains a reference to the shared pointer returned by HttpServer::CreateSession(). It's a hack but mostly works.

An additional issue that will result if I'm holding a reference to the session is a race when a client disconnects on timeout and before onDisconnect is called. The deferred response might become available and be written to the file descriptor that has since been opened to a new client, thus passing data to a client unrelated to the original session.

Data race in TCPSession

_server->_bytes_sent += sent; and _server->_bytes_received += received; could be called from different sockets on different threads.

HTTP server silently drops some requests

I'm seeing that some GET requests get silently dropped by the server, e.g. I see the request in WireShark, but HttpSession::onReceivedRequest method doesn't get called. The same exact request retried in a few seconds works. I wonder what's the best way to troubleshoot this problem.

Are you sure your macros is working correctly?

This API is only called in your lib

linux install

How can I install CppServer on a system. So it can be used with my own cmake project.
I tried using cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr/local ..

and when I do make install
it only copies the binary's to CppServer/bin

it looks like the CMakelists.txt file doesn't have install targets for the headers and lib.

Building on Ubuntu 20.04 LTS

When building the library on Ubuntu 20.04 LTS, I needed to install the following packages before the built went through:

doxygen
libbfd-dev (which actually installed Paket binutils-dev)
uuid-dev

Yes, binutils-dev and uuid-dev are listed as prerequistes in the main README.md. But I must admit, that I overread these at first. I recommend changing the lines:

* Linux (binutils-dev uuid-dev libssl-dev)
* OSX (openssl)

to:

* Linux specific:
  * binutils-dev
  * uuid-dev
  * libssl-dev
  * doxygen (for building the documentation)
* OSX specific:
  * openssl

During the build, I also got this warning/error:

-- Could NOT find LIBVLD (missing: LIBVLD_LIBRARY)

However, this did not stop the build from running through. Is LIBVLD no more necessary?

The pre-installed OpenSSL library was found during the built:

-- OpenSSL version: 1.1.1f /usr/include /usr/lib/x86_64-linux-gnu/libssl.so;/usr/lib/x86_64-linux-gnu/libcrypto.so

Nonetheless, during gil update during the install, OpenSSL was downloaded (precompiled for Windows?) as a module. The binaries compiled during the built use the system OpenSSL library, though. I am always a bit scared, if a library is present twice (once in the system, once in a local version), as this can lead to serious issues later, when one version of the library is used for compilation and the other version is used for linking. I removed OpenSSL from the modules directory and the compile still went through, though.

People, that also have the Boost C++ library installed, might want to use boost::asio instead of Standalone libasio. You could add that as a configuration option, too, or autodetect an installed and recent enough boost and then use its asio automatically. I believe, the major difference between standalone libasio and boost::asio is the path of the include files (for example asio.hpp become boost/asio.hpp) and the namespace (boost::asio vs. asio). It shouldn't be hard to adapt between the two via a few #ifdef's.

Unfortunately, the header files and libraries are not automatically installed into the typical system-wide directories /usr/local/include and /usr/local/lib. Furthermore, your libraries hold very generic names like time/time.h or utility/iostream.h, which are very near hits on system include files like <time.h>, <utility> or <iostream>. So that more people can base their work on your nice libraries, I strongly recommend, that you choose a unique path prefix like chronoxor.

Unfortunately, adding that prefix would make your includes in the CppServer projekt very long, like chronoxor/server/http/http_response.h. I believe, you could leave out the server subdirectory. That name is even misleading, as you also implement the client side! chronoxor/http/http_response.h is still unique and clear enough. You could even leave out the http_ prefix on the files in the http directory and the ws_ prefix on the files in the ws directory. chronoxor/http/client_ssl.h should be clear enough to everybody :-)

Thank you again for the good work 🥇

How do you actually link this to your own project?

Hi,
This seems like a trivially simple question, but I haven't been able to find a solution for this anywhere. I have my own project that uses Gnu Make and I want to use a few of the modules from this package.

For example, assume that I copy the Asio service example from the README into a new file outside of the CppServer project:

#include "server/asio/service.h"
#include "threads/thread.h"

#include <iostream>

int main(int argc, char** argv)
{
    ...

What are the steps to actually link and build this? I managed to convert things to GMake using cmake -G "Unix Makefiles", but these files have no concept of or reference to the source files. It seems like the CppServer project is only built around creating its own internal example files. Any help is greatly appreciated.

Thank you

Data race in SSLClient

Imagine that while receiving data, an error occurs, it causes calling Disconnect, that causes calling onReset, where _pimpl is reset. But at the same time a different thread can try send data, using any of Send methods, that calls pimpl() method, that returns a reference, that might be reset in onReset method.

Catch2 package issue when clone and building

Hi @chronoxor

There are 2 issues when using the external package Catch2:

1: The branch name change from 'master' to 'devel', when python gil clone this package will show can't find this package, I clone the latest 'devel' to modules files to solve this problem.

2: The latest Catch2 package remove the file single_include, so when building this project it will show can't find this file when building.

First problem:

Working path: /Users/chihungchung/Documents/CppServer
Discover git links: /Users/chihungchung/Documents/CppServer/.gitlinks
Running git clone https://github.com/catchorg/Catch2.git branch "master" into /Users/chihungchung/Documents/CppServer/modules/Catch2
Cloning into '/Users/chihungchung/Documents/CppServer/modules/Catch2'...
fatal: Remote branch master not found in upstream origin
Traceback (most recent call last):
  File "/Users/chihungchung/opt/anaconda3/bin/gil.py", line 412, in <module>
    sys.exit(main())
  File "/Users/chihungchung/opt/anaconda3/bin/gil.py", line 401, in main
    context.clone()
  File "/Users/chihungchung/opt/anaconda3/bin/gil.py", line 155, in clone
    self.git_clone(value.path, value.repo, value.branch, args)
  File "/Users/chihungchung/opt/anaconda3/bin/gil.py", line 308, in git_clone
    raise Exception("Failed to run git clone %s branch \"%s\" into %s" % (repo, branch, path))
Exception: Failed to run git clone https://github.com/catchorg/Catch2.git branch "master" into /Users/chihungchung/Documents/CppServer/modules/Catch2

Second problem:

May be I clone the older branch of Catch2 can solve this problem?

Compiling error on Ubuntu 16.04

Dear chronoxor,

When I try to build CppServer on Ubuntu 16.04, it got an error below.
Could you know the environment and compiler to build it?

Thanks!
