1st of all threads_no() returns the SIZE of the thread pool and not the "specific thread ID".

So you'll see the same number.

Where do you think you are blocked? What is the output? Are you sure the loop completes? Print something before you "post -back"
to the event loop.

I don't see any specific problem why wouldn't it work.

 Sure,
 
 I want an asynchronous application to
 handle some requests assigned to the dispatcher.
 Then for each request, a long running
 task is to be created. Therefore I want it to be executed
 not in the event loop and block the complete process.
 
 
 What I thought would happen was the
 jop posted via thread_pool().post would have been executed
 in a thread from the pool, not blocking the event loop nor
 the request handling.
 What I encounter
 is that the asynchronous application is not able to handle
 further requests while the first job is running, but rather
 enques them and processes them one after another.
 
 However, a timer I implemented with boosters
 deadline_timer is continuously triggering (not included in
 the code). So I guess the event loop is not blocked, but the
 application is.

 Hey all,
 I try to run an

 using the following code:
 http://pastie.org/private/9kuhjwvrzswmnpoczvvqw
 
 
 This seems to not block the eventloop, but
 the eventhandler gets called
 in the same

 not responding to new incoming

 Is this the way

 What would be the correct application design to execute a

Hi,

Please ignore,

I could make it working by simply mapping it with url along with other
sub-applications. like:

attach( new app_user::User_controller(s),
"user","/user{1}","/user(/(.*))?",1);

attach( new app_user::User_json_service(s),
"rpc","/rpc{1}","/rpc(/(.*))?",1);


Thanks for such a great framework Artyom. Its love developing with it.

Regards,
Abhishek

Hello Artyom, CPPCMS Developers,

I have a main function defined as follows:

int main(int argc,char **argv)
{
  try {
    cppcms::service srv(argc,argv);
   
srv.applications_pool()
.mount(cppcms::applications_factory<app_common::Main_controller>());
   
srv.applications_pool()
.mount(cppcms::applications_factory<app_user::User_json_service>());
    srv.run();
  }
  catch(std::exception const &e) {
    std::cerr << "Failed: " << e.what() << std::endl;
    std::cerr << booster::trace(e) << std::endl;
    return 1;
  }
  return 0;
}

app_common::Main_controller : is the normal application, which contains url
dispatcher bound to their relevant methods.

app_user::User_json_service : is an RPC application.

However, when I run the method, I see that app_common::Main_controller works
as usual, however, I don't see app_user::User_json_service responding to any
url calls.

In config.js, I have added 

"http" : {
      "script_names" : ["/lb","/rpc"] ,
      "rewrite" : [
         { "regex" : "/media(/.*)?", "pattern" : "$0" },
         { "regex" : "/rpc(/.*)?", "pattern" : "/rpc$0" },  
         { "regex" : ".*" , "pattern" : "/lb$0" }


But the RPC never works here. Can you tell me a proper way to do it? is it
possible to added multiple application in the pool and get working? Or do I
require have a different server dedicated for doing RPC work only?

Please let me know.

Regards,
Abhishek

Hi Artyom, 

Thanks for your reply.

I have discovered the use of content varaible in template code using <% c++
.... %> and have solved my problem. I was about to post this, just to save
your time in answering me. 

> if you want to access the object itself. What do you expect to do with it?
If you access an object you access its members.

We can have this case:
	<% form as_p form %>
Rather than passing an object which wraps a form, we could have passed the
form object directly to the render function. However, I don't think that
would be possible, since form isn't inheriting from base_content (and doing
multi-inheritance may be bad.)

However, even without this, development is still going at our end smoothly.
And this was just a design opinion that popped (due to habits of using
Spring MVC, etc.). However, I don't think, cppcms template design is any
less in any way.

Regards,
Abhishek

Can you please send the code via attachment/inline and not "pastie" and explain in more details what happens?

I'm not 100% sure I understood your question.

If you need to pass a complex structures you can part them as a member of "content::message"

if you want to access the object itself. What do you expect to do with it? If you access an object you access its members.

Now technically <% = text %> is converted to C++ code like: out() << content.text; (not exactly as there are filtering and some more stuff) so if you embed C++ to the code you can actually access c as "content" variable.

Now one important restriction is that "c" is actually derived from cppcms::base_content

http://cppcms.com/cppcms_ref/latest/classcppcms_1_1base__content.html


Which is polymorphic class and safe dynamic casting can be done to ensure you actually use right object withing the template.

Note templates may be loaded dynamically and compiled independently.

Hey all,
I try to run an eventhandler inside of an asynchronous application,
using the following code:
http://pastie.org/private/9kuhjwvrzswmnpoczvvqw

This seems to not block the eventloop, but the eventhandler gets called
in the same thread the application runs in, resulting in the application
not responding to new incoming requests.

Is this the way it is designed or am I screwing up again :-[ ?
What would be the correct application design to execute a 'background'
job in the thread_pool, while not blocking the incoming requests?

Greetings,

I have been following the CPPCMS tutorials regarding view rendering.

What I see mostly is that when you render your data (let's use the example
of content::message)

so we have:

    content::message c;
    c.text=">>>Hello<<<";
    render("message",c);

and then in the templates, we use this data as:

<% view message uses content::message %>  
<% template render() %>  
<html>  
  <body>  
    <h1><%= text %> World!</h1>  <-- this is a part of message.
  </body>  
</html>  
<% end template %>  
<% end view %>  

==========================

What I wanted to know, is there a way to access "message" object in the
template, directly? Like instead of doing:

<%= text %>, is there any way where I can refer the actual parent object:
like <%= message.text %> ?

The advantage I will have is, that while calling the render method (as in
render("message",c);), I would be able to pass my data directly.

Let's say in the Message Board's Example. If you see the passing of
data::forum to templates, you were required to construct a parent kind of
object, which would contained vectors to topics, etc. But if you see from
the usage or design point of view, it would be great if I were able to pass
the topics directly, without making it require a parent kind of wrapper.

Let me know, if there exists any way to achieve it.

Regards,
Abhishek

Thanks, That did work!

Hi,

I am working on an application and have a very simple requirement.

Its just that I want all the requests being made to the server should pass
an authentication criteria.

If the requests are valid (based on session checks), let them continue or
else redirect them to a login page.

I have created one such implementation as shown here:

void main_controller::manage_default(std::string page) {
    if(page == "/login") {
        if(session().is_set("username")) {
            response().status(cppcms::http::response::found,url(""));
        }
    } else {
        if(!session().is_set("username")) {
            response().status(cppcms::http::response::found,url("/login"));
        }
    }
}

but this function (manage_default) is mapped to default url (i.e. ""). So it
won't be called if user calls some other pages like /view_bills (without
touching the base url).

So is there a way where I can capture all such requests at a single place
and then allow such requests to continue further?

Regards,
Abhishek

Because std::string isn't Plain Old Object - it has constructor/destructor etc. You can't serialize it as POD you need to serialize all its members independently

Hello,

Since a new release is planned, would you consider the patch I submitted 
for the following feature request "#17 make the skin generation order 
independent" ?

http://sourceforge.net/p/cppcms/feature-requests/17/

Thanks,

Dear Stanimir!

Thank you for your help!
It is not 100% solution for my problem, but it will simplify my life.
Also I will create feature request in sf project. Maybe Artyom could add
requested functionality.

There is two "get" member funtions.
One with string param that is handy to get the parameter by name directly.
The other is get() without params. Look at the link to the documentation.
http://cppcms.com/cppcms_ref/latest/classcppcms_1_1http_1_1request.html#a36d72816584f61d3c5b7e510d61a5f58

The former returns form_type which is
typedef std::multimap<std::string,std::string>
cppcms::http::request::form_type

Dear Stanimir! Dear All!

function request().get() doesn't return
std::multimap<std::string,std::string>.
probably you meant about request::getenv() function, that return
std::map<std::string,std::string>, but this function returns all CGI
variables.
http://cppcms.com/cppcms_ref/latest/classcppcms_1_1http_1_1request.html#a92bc86f75e4e1f9480967ce3fd1e4f65

when using request::getenv() function all variables of requested URL and
it's values are all in one QUERY_STRING key.
so parsing QUERY_STRING with such complex associative array notations is
not trivial task.
for example for one of the request QUERY_STRING looks like, and its
nightmare to parse variable unknown length and unknown of numbers of
variables string:

draw=1&columns[0][data]=0&columns[0][name]=&columns[0][searchable]=false&columns[0][orderable]=false&columns[0][search][value]=&columns[0][search][regex]=false&columns[1][data]=1&columns[1][name]=&columns[1][searchable]=true&columns[1][orderable]=true&columns[1][search][value]=&columns[1][search][regex]=false&columns[2][data]=2&columns[2][name]=&columns[2][searchable]=true&columns[2][orderable]=true&columns[2][search][value]=&columns[2][search][regex]=false&columns[3][data]=3&columns[3][name]=&columns[3][searchable]=true&columns[3][orderable]=true&columns[3][search][value]=&columns[3][search][regex]=false&columns[4][data]=4&columns[4][name]=&columns[4][searchable]=true&columns[4][orderable]=true&columns[4][search][value]=&columns[4][search][regex]=false&order[0][column]=1&order[0][dir]=asc&start=0&length=10&search[value]=&search[regex]=false&_=1403203600182

So I still looking for solution. Or should I create feature request?

Thanks in advance!

You have request().get() ->
http://cppcms.com/cppcms_ref/latest/classcppcms_1_1http_1_1request.html#a36d72816584f61d3c5b7e510d61a5f58

which returns std::multimap<std::string,std::string>

The first is your parameter name and the second its value.
Note that a parameter could be any type serialized as string. Like an ISO
Date (2014-05-24).
It is you responsibility to parse those values and convert them to your
appropriate c++ representation, since CppCms can't know every type you need.

Dear All!

I need to parsing complex variables and its values in URL which have the
form like:
variable[index1][index2]...[indexN]=X, where index1-N,X could be integer,
string, boolean.
For example, such notation have new version of jquery DataTables 1.10.0.
http://datatables.net/manual/server-side
Also such associative array notations using in variables in forms.

What is the best way to parse such complex variables and its values?

The best option for me is packing variables and it's values from URL to c++
structures as is done in php and other languages.
Unfortunately cppcms::http::request or other classes haven't such
functionality.

Thanks in advance!

There are several important bugs I need to fix so it should be
ready withing a week or two.

Currently I have following problems (before a release):

(a) A newly booster.thread test fails on FreeBSD I need to find why it may be a serious bug
(a) The ICU test fails with ICU version >= 50. It is either ICU bug or just a change that I need to ignore in the test so I'm waiting for a answer from ICU team.

It changes the ABI in "forward compatible way" only - it adds a new API.
It should be done for major versions only.

If I add more API changes I need to consider more stuff that is even more 
important - like for example accessing cache outside the application
to fire triggers and some other things.

I have seen you did some commits and would like to know if you are

a new version soon? Would it be possible to merge the following commit
from trunk into v1.0_fixes branch?

r2231: Read only attribute support, closing #13

Yes there is a reason behind that.

The policy is if set() is false that accessing value() would throw an exception.

Blank text is still a valid text the empty string is still a text - i.e. you take value() and it is valid, on the other hand if there is no number or there is no uploaded file, than  there is no reasonable value() and than you must check the set() properly.
