suggestion: add move operations for cppcms::json::value
Hi，thank you for your amazing library！
We have been using cppcms framework for a restful server lately。
As it is very often for us to dynamically generate JSON object，json::value generation speed is very important. We have add move constructor and move assignment operator for json::value, turns out it speed up about 30-60% in a large JSON object generation.
So, why not add the move operations when the compiler have move operation support?
Thank you again for your brilliant library!

Looping over a temporary vector leads to error.
Problem
The generated style of the foreach loop is not a good design choice. It breaks when looping over temporaries.
Insights
Let's say we are in this situation:
struct Object {
std::vector<T> allTs();
};
struct message {
Object o;
};
And the view is trying something like:
<% foreach t in o.allTs() %>
<ul>
<% item %>
<li><%= t.name() %></li>
<% end %>
</ul>
<% end %>
Consider now that the function signature may look like std::string_view T::name() const; and that Object::allTs() is constructing a new std::vector every time it is invoked.
When we look at the C++ Code for the view it looks somewhat like:
for(
auto t_ptr = (content.o.allTs()).begin(),
t_ptr_end = (content.o.allTs()).end();
t_ptr != t_ptr_end; ++t_ptr) {
auto& t = *t_ptr;
With this setup t_ptr is a iterator value of a temporary object (which might be already gone) and t_ptr_end is a iterator value of a second temporary object (which might also be gone).
So any call to t is basically broken. So if t.name() now returns a string_view then we can be pretty sure (and that's precisely the problem I currently have) that the viewed memory section is not valid.
Solution
Change the generator to produce code that looks like:
{
decltype(content.o.allTs()) t_iterable = content.o.allTs();
// I dropped the if condition for simplicity
for (auto t_ptr = t_iterable.begin(), t_ptr_end = t_iterable.end();
t_ptr != t_ptr_end; ++t_ptr) {
auto& t = *t_ptr;
// Stuff
}
}
BUT PAY ATTENTION to the use of auto vs decltype. Every auto keyword in this code is the expansion of the CPPCMS_TYPEOF macro. But when you use auto in the case above you may introduce unnecessary copies. That is because auto won't deduce to a reference-type. So if allTs() returnes a std::vector<T>& auto will deduce to std::vector<T> and you will copy the whole vector. decltype on the other hand will deduce to std::vector<T>&.
whether the json object is iterable ?
cppcms::json::value my_object;
my_object["name"] = "Moshe";
my_object["salary"] = 1000.0;
my_object["retired"] = false;
for (/* iterate the json object */)
{
std::cout << "key: " << it.key() << " value: " << it.value() <<std::endl;
}
I just want to get the output like this, do you have any idea to do this ?
key: name value: Moshe
key: salary value: 1000.0
key: retired value: false
I'll apperciate your reply.

Request method PATCH does can not load(context()) to form elements
I'm trying to write Rest APT, that uses PATCH and more another method.
But it can not load(context()) to the cppcms::form. When I change Route form PATCH -> POST, it working successfully.
After read documentations, I heard that now load(context()) only extract data from POST/GET
What should I do to implement full Rest API style?
Twice rendering in main?
I 've test add #include <stdio.h> to hello.cpp file and do a printf and this is result:
Code:
void hello::main(std::string /*url*/)
{
response().out() <<
"<html>\n"
"<body>\n"
" <h1>Hello World</h1>\n"
"</body>\n"
"</html>\n";
printf ("Characters: %c %c \n", 'a', 65);
}Then i open browser once, but result is print twice:
Result:
Characters: a A
Characters: a A
Is it run twice in code?

applications_pool_size
Hello.
- Can't find applications_pool_size within sources any more. What is the way to manage sync applications pool size (and thread pool size)?
- In my typical case I process a request by async app and find out that long-running job is needed, so I want to pass the job (partially done) to different thread to continue processing. Now we have submit_to_asynchronous_application and submit_to_pool now. Whether the only way to link these two parts of code is to pass a key via url (to search for the job in some custom storage)? I suspect that thread_pool could be useful in job-centralized processing, but it's hard to get the way it works in conjunction with applications. As a result: custom queues and custom adjustable thread pools. Please, direct me how to use cppcms natively for such a task.

cppdb: show tables like query arguments not bound
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?

UDS permissions (feature request)
When using unix sockets to run a service, they are created with default user/group/permissions on the location specified in config.js. It would be nice to have some possibility to setup the permissions in the config.js, so that e.g. the service may be started as a user, but still allow to communicate with, say, nginx server using a socket with permissions for some common group.
Some ugly proof of concept to show what I mean (config.js contains "user" "group" "perms" in the "service" section along with socket):

Failed to upload files from REST API I create with cppcms
HI
I'm using CPPCMS to create a RESTful API. But now i have a little problem and i need your help. I want to allow external client to upload files like image using curl. But i wonder myself how to get this file and save it on the server.
Example of command i want the client use:
curl -i --data @image.png --url http://myweberser.com:8080/api/upload
Can't use dispatcher url
I'm trying to make an dispatcher like this but it does not work when build:

What is the recommanded way of testing a cppcms::application?
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:
- Create a new cppcms::service.
- Create a new cppcms::application <-- my REST server
- Call application.main("url_path")
- 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.
cppcms_tmpl_cc gives traceback issue
I am following this tutorial. The project was built successfully up to the end of Static Linking.
Then I want to make a custom makefile to use it with Eclipse CDT. After much tinkering makefile and many build cycles, cppcms_tmpl_cc gives me a traceback issue as follow:
$cppcms_tmpl_cc my_skin.tmpl -o my_skin.cpp
Traceback (most recent call last):

File "/usr/local/bin/cppcms_tmpl_cc", line 1160, in main
output_fd=open(output_file,"w")
IOError: [Errno 2] No such file or directory: 'my_skin.cpp'
Does anyone have a way to fix this? I plan to rebuild CppCMS as no solution has been found.

cppdb and JSON data type
MySQL 5.7 introduced a new JSON data type.
cppcms also has a JSON class.
The cppdb documentation apparently says nothing about supporting JSON. Can we use operator>> and operator<< with a cppcms::json object to directly get or save JSON data into a MySQL JSON field?
If not, what would be required to get cppdb to conveniently bind MySQL JSON data to a cppcms JSON object?
Synchronous applications being deleted during heavy load
During heavy loads (ie DDOS, brute force password attempts), it is common to see constructors and destructors of my application being called rapidly.
This has the side effect of abruptly terminating existing requests which are still running.
I've looked at the application_pool.cpp file and the policies seem to imply that delete app should never be called?
I am using cppcms 1.04
what is Number of concurrent of cppcms
i use cppcms version 1.2.1 on windows as a web application, test http post max concurrent number.
after the server receive a request , then post request to the threadpool , the workthread fetch the request and send reponse to client .
i use the third http client tool "ab" test the concurrent number of all request and response, the max number is about 4000 per second.
how to use cppcms to achieve larger concurrent number? is there a example?
Load json::value from file
I have a manifest.json file like this:
{
"js/app.js": "js/app.112sf342isw1.js"
}I'm trying to read it by ostream in cppcms::json::value but it not work:
const std::string urlPath = "js/app.js";
std::ifstream f("manifest.json");
cppcms::json::value v;
v.load(f);
std::cout << v[urlPath].str() << std::endl; // It throw exception not found the key
std::cout << v.at(urlPath).str() << std::endl; // also not found exceptionI think the json file has a . in key string, so it can not parse correctly. But i don't know how to solve this issue.

Building a multi-layered page with CppCMS
I am trying to build a multi-layered CppCMS page. I use the render() command along with the POST event from a click on a cppcms::widgets::submit object on each page. This is giving me lots of errors and I do not know how to fix them. How exactly do you do URL dispatching with a click on any cppcms::widgets::submit object? Thanks.

test_aio_socket fails (clang-3.9, BeagleBoneBlack)
Built libraries under BBB and only one test failed: test_aio_socket. However, I tested a program I have that uses aio sockets and seems to work fine. Please see LastLog output and compilation environment in bug_report.txt. You have the full make; make test; make install output in compilation.txt
Best regards,

Warning on readdir_r function
During build process of cppcms-master, I had this warning (see attached file)
warning-on-readdir_r.txt
upstream sent unsupported FastCGI protocol version: 6 while reading upstream
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.
feature: datagram_socket in booster::aio
It would be nice to see class datagram_socket, similar to stream_socket, be implemented in booster::aio.
If it is too simple to implement, a tutorial will be very good, too.
404 error for media/style.css
In the messageboard example, the css file style.css is not being read. Any suggestions? I tried placing the media folder in multiple places, but that didnt work too. Keep getting a 404 error for localhost:8080/media/style.css
translating links
In my template I had this:
Hello <a href="<% url "/user" using userId %>"><%= userId %></a>
Now, when adding translations I wanted to do something like this:
<% gt "Hello <a href=\"{1}\">{2}</a>" using ( url "/user" using userId ), userId %>
but it seems, that's impossible.
What is the proper way of handling such situations? Adding new field to the data with generated url? Translating just "Hello" is an option, but it won't work for longer texts.
Program produces 100% CPU load on one core
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)

How to update/upgrade app while runtime
Some time I want to edit a code in cpp file, but website is running, in PHP or NodeJS, it so easy to edit at localhost then test, then i can push to github and pull in from server and don't need reset server or turn app to "In construction" status.
How to do it in CppCMS?
valgrind: Conditional jump or move depends on uninitialised value(s)
I was testing my application with valgrind, trying to clean up warnings.
I was able to reproduce one of those in the example code distributed with cppcms:
After making the example in examples/form:
~/cppcms/examples/forms/ $ colour-valgrind ./hello -c config.js
Just after starting up, there are a few warnings:
Use of uninitialised value of size 8
And after hitting http://127.0.0.1:8080/hello , the warning that I was trying to debug appears:
