Hi. I started working on a new web project and decided to check out this framework. I have to say: It's is really nice. I like it a lot.

But here's the thing: When I start the application on my laptop everything works fine. My process explorer says that the application is sleeping and using less than 1 MiB of RAM. Then I load the first page => Process wakes up allocates RAM, does its thing and goes back to sleep. So far so good. But then it randomly decides, that now is the time to do some work. The CPU usage climbs to 12% (which is 1 core on full power on an octacore system) and stays there. I have no idea what the program is doing.

Where do I start to debug?

Thanks in advance. Martin

(P.S. I'm on Debian 9.2)

Unable to send big response (~223kb) from cppcms via fastcgi to nginx cppcms: cppcms, warning: Failed to write response:system: Connection reset by peer (http_response.cpp:305) NGINX (1.8.1): upstream sent unsupported FastCGI protocol version: 6 while reading upstream

Changing nginx buffers does not help.

the code flow is about this:

cln_job->http_context->response().out() << body;
cln_job->http_context->async_flush_output(
                        bind(&dispatcher_app::flush_output_handler,
                             booster::intrusive_ptr<dispatcher_app>(this),
                             std::placeholders::_1,
                             cln_job));

Inside flush_output_handler() i do

    job->http_context->async_complete_response();
    job->http_context.reset();

immediately. It looks like the problem is here, but i can't find info on how to process big response.

issue found in http_request.cpp, method int request::on_content_progress(size_t n), at line 357

if (!f->has_mime()) is error, right way is Judgment file type， please author affirm

Hello,

I have a REST server implemented as a cppcms::application. I would like to add some tests for it. I don't really want to do a network request, but only set the application context, call the main method and check the response. Is it possible? What would you recommand?

What I have tried so far:

1. Create a new cppcms::service.
2. Create a new cppcms::application <-- my REST server
3. Call application.main("url_path")
4. Check application.response()

Between 2) and 3) I probably need to call cppcms::application::assign_context(). But there is no way to create one as its constructor depends on impl::cgi::connection.

As we know, std::auto_ptr was deprecated in C++11 and fully removed in C++17. While it is still possible to build CppCMS without using C++17, std::auto_ptr uses in the public part of API causing compilation errors if C++17 is a must. That's why, in the current form, there is no way to use CppCMS alongside C++17 header-only libraries.

In order to fix this problem, we can replace std::auto_ptr with std::unique_ptr in all public header files (i.e., the files which are installed into include/ dir). Then, we can proceed with replacement until the codebase can be compiled without any compilation errors.

In this patch, following steps are followed:

• Prune std::auto_ptr from public header files.
• Modify private header files and declaration in source files to match public part.
• Modify function/template implementation and preprocessor macros until all compilation errors eliminated.
• After modifications, run tests again to ensure there is no illegal pointer dereferencing.

The following:

#include <iostream>
#include <cppdb/frontend.h>

int main() {
        std::string dbcs ="mysql:database=mydb;user=myuser;password=mypassword;@pool_size=10;set_charset_name=utf8";
        auto sql = cppdb::session(dbcs);
        cppdb::result res;
        std::string table("my_table");
        res = sql << "SHOW TABLES LIKE ?" << table;
        res.next();
}

produces:

terminate called after throwing an instance of 'cppdb::mysql_backend::cppdb_myerror' what(): cppdb::mysql::You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?' at line 1 Aborted

The same code but with a different query (e.g. a SELECT query) can properly bind the arguments, but for some reason, the 'show tables' query above does not work with bound arguments.

Also, could cppdb_myerror output the full query? I checked the cppdb source code and I couldn't see any obvious way to have a more detailed error message being thrown. However, when developing an application, it is sometimes hard to debug code and queries because the exact query which causes to throw is not displayed. Above is a good example of that: the error thrown tell about "the right syntax to use near '?' ", but it does not show the actually query "SHOW TABLES LIKE ?".
How hard would it be for the full query to be thrown together with the error?

GCC is 5.4.0 the stock compiler and libraries are all default libraries.

client:

let fd=new FormData();
fd.append('name','myname');
fd.append('image',e.target.files[0]);
fetch('/upload',{method:'POST',body:fd});

server:

!request().files().empty() used to return true within the block if(!request().is_ready()). Recently it started to return true within the block if(request().is_ready()).

Exactly where should the check if(!request().files().empty()) be done?

Thank you in advance!

class my_upload: public cppcms::application {
public:
void main(std::string path) {
	if(!request().is_ready()) {
		session().load();
		if(!request().files().empty()){ //Used to be true
			request().files()[0]->set_temporary_directory("/tmp/uploads");
			request().files()[0]->set_memory_limit(512);
		}
	}
	else {
		if(!request().files().empty()){ //Is true now.
			request().files()[0]->set_temporary_directory("/tmp/uploads");
			request().files()[0]->set_memory_limit(512);
		}
		release_context()->submit_to_pool();

I am trying to render geo map by using next command:

<object type="image/svg+xml" data="/media/svg/map.svg" width="500" height="500" ></object>

But map is not rendered... At the same time, if I use this command in HTML file locally, is works fine.

Hi I'm trying to create a Dockerfile that runs a CppCMS application in a NGINX web server. However, the command make tests always returns that the tests fail at test_locale_format , test_locale_boundary and test_aio_socket . The two first are solved by applying the option -DDISABLE_ICU_LOCALE=ON. I checked if the image has some services using the port 8080, but it's not the case.

Specifications:

• OS: nginx:1.19.7 : Docker image with nginx in Debian OS
• Docker-Compose file

version: "3.9"
services: 
  app:    
    build:
      context: "./app"
      dockerfile: ".docker/Dockerfile"
    volumes:
      - ./app:/etc/nginx/sites-available/
    ports: 
      - "8090:8080"

• Dockerfile:

I currently have a form in my application, but if I don't upload a file in the form the form will fail to validate. Here are the relevant parts of my content.h

struct submit_op_form : public cppcms::form {
  cppcms::widgets::file image;
  submit_op_form() {
    image.limits(0,500*1024);
    image.mime(booster::regex("(image/(png|jpeg))|$")); //Allow mimetypes of either image/png or image/jpeg

    image.filename(booster::regex("([_a-zA-Z0-9]+\\.(png|jpg|jpeg))")); //Allow filenames of the form [text consisting of alphanumeric characters].png/jpg/jpeg
    image.mime(booster::regex("(image/(png|jpeg))")); //Allow mimetypes of either image/png or image/jpeg
    image.add_valid_magic("\x89\x50\x4E\x47\x0D\x0A\x1A\x0A"); //magic numbers for png files
    image.add_valid_magic("\xff\xd8"); //magic numbers for jpeg files
    image.add_valid_magic("");
    add(image);
  }
  virtual bool validate() {
    if (!form::validate()) {
	return false;
    }
    return true;
  }
};

More specifically, I never called image.non_empty() and I added an empty string as a valid magic number but the form still fails to validate.
