[Cppcms-users] load balancing & scalability

[Aris S. <ari...@gm...>]

Hi,

Can CppCMS be load balanced using cluster mechanism to handled high
load user? What I mean here is some like horizontal scalability which
I can add new server node to increase throughput.

Maybe I still don't believe (but also exciting) if I can use powerful
C++ in web development.

Recently I develop small (but 7/24 running) application which
concentrates many mysql database to a single centered mysql database.
I have port it 4 times in 2 days, from Java + JDBC, then
C#.net+NetConnector, then C#+ODBC, then C#+OLEDB, at last
C++(C++Connector), for solve memory leaking and to handle interrupted,
slow network connection.

Of course you can,
Why shouldn't you be able to do this?

CppCMS is just a library, you can use what ever you like with it.

[Cppcms-users] external library

[Aris S. <ari...@gm...>]

Hi,

As in desktop programming with Qt or VisualC++ or  GCC; can I use
external library or dll (eg: C++ client VoltDB library, C++ MySQL NDB
client library, etc ) in developing web with CppCMS framework?

[Cppcms-users] Reply to Settings in cppcms-users list

[Artyom <art...@ya...>]

Hello All,

I've changed reply-to settings such that, by default the reply goes
to the cppcms-users mailing list and not to the sender.

This will reduce number of mistakes, in replying to mailing list, but
you'll have to specify mail address explicitly if you want to
send an e-mail privately.

I just suggested, of course you do what you need.

First take a look in cppcms/json.h file
there are some specializations for std::vector, std::map, std::pair
and some other basic strings they would give you a clue
how to start

All you need to implement get and set static members:

For example (I hadn't tested this code):

struct person {
   std::string name;
   double salary;
   std::vector<std::string> kids_names;
};

namespace cppcms {
namespace json {
    template<>
    struct traits<person> {
            static person get(value const &v)
            {
               person p;
               if(v.object().size()!=4)
                   throw bad_value_cast();
               p.name=v.get_value<std::string>("name");
               p.salary=v.get_value<double>("salary");
               p.kids_names=
                  v.get_value<std::vectror<std::string> >("kids_names");
               // this works because generic vector and string specialized
            }
            static void set(value &v,person const &in)
            {
               v.set_value("name",p.name);
               v.set_value("salary",p.salary);
               v.set_value("kids_names",p.kids_names);
            }
    };
} // json
} // cppcms

Note1: By convention, faults in conversion should throw bad_value_cast
  so some functions can catch them and substitute with defaults if needed.

Note2: current internal HTTP Server supports GET, POST and HEAD
  requests, so you need to work via FastCGI or SCGI API behind
  the browser.

  I can add support of PUT and DELETE just tell if you need.
  But remember that you should not use internal HTTP server for production
  environment as it build for debugging purposes.

  You may probably use it in trusted environment as it does not
  do too much security checks.

Re: [Cppcms-users] CppCMS 1.x.x JSON object value empty/not exist

[Artyom <art...@ya...>]

BTW I forgot to mention, cppcms provides built-in JSON-RPC facilities:

See: 
  http://art-blog.no-ip.info/cppcms_ref_v0_99_1/classcppcms_1_1rpc_1_1json__rpc__server.html 

And a simple example in "tests/jsonrpc_test.cpp"

Subject: [Cppcms-users] CppCMS 1.x.x JSON object value empty/not exist

Hi,

I'm trying to use cppcms for a new project and use it for building a
RESTLike API for a device. The API will communicate with the JSON data
format.

When receiving JSON data from a client some fields of an object are
optional. I'm using json::value for handling this.
I use the get<T> function to fetch the fields but in case of a missing
field or invalid field data it throws an exception. Is it possible to
detect that the field is missing separately? So I can ignore missing
optional fields.

Tnx

Re: [Cppcms-users] CppCMS 1.x.x JSON object value empty/not exist

[Artyom <art...@ya...>]

Yes you can.

Simplest way is to use get with default parameter. For example

json::value v;

v.get("foo.bar",10);

And if foo.bar is not defined or invalid you get 10 instead.

You can also use find member function and test the type:

if(v.find("foo.bar").type()==cppcms::json::is_number)
  ...
else
  ..

Take a look on documentation of: cppcms::json::value

  http://art-blog.no-ip.info/cppcms_ref_v0_99_1/classcppcms_1_1json_1_1value.html
or (mirror)
  http://cppcms.sourceforge.net/cppcms_ref_v0_99_1/classcppcms_1_1json_1_1value.html

Especially functions: find(), at(), get() they allow you to browse the object on different paths.

Regards,
Artyom

Re: [Cppcms-users] CppCMS 1.x.x status updates.

[Artyom <art...@ya...>]

No, it is not, 

It supports Comet over long-poll and other non-HTML5 techniques.
Most browsers do not support this HTML5 feature and long-polling XHR is much more
reliable and supported among moder browsers.

However CppCMS provides generic sockets API so it can be implemented and integrated
to the CppCMS event loop, also there is no limitations to add WebSockets support to
CppCMS in future.

Re: [Cppcms-users] make test failed

[Artyom <art...@ya...>]

Hello 

The "stock" application is just a small server side part API only.

At localhost:8080/stock/update 
  you have a form that allows you to update a price
  and using

At
  localhost:8080/stock/get?from=NUMBER

You can get NUMBER'th price. So if you didn't get it yet you'll
wait for update from server.

For little bit better comet application try chat application:

go to src directory and run

../build/hello_world -c config.js

Now you can go to localhost:8080/the_chat.html and chat ;-)
Of course it is very simple one especially on the client side were
I almost don't do any checks.

It is written mostly to check that comet works.

Re: [Cppcms-users] make test failed

[Jean-Michel C. <jea...@la...>]

Hello,

I did a new test with your lastest cppcms 1.x.x on a new Debian testing system. All works :)

I can run hello app but I cannot run chat or stock app. To run stock app, I use this url :

http://127.0.0.1/hello_world/stock

Is it correct ?

Thanks.

Ok: 

1. What version are you using (svn revision number)
2. It looks like something went wrong...

Can you send the error log?
It us under your build directory: Testing/Temporary/LastTest.log

Also please provide following information:

- Testing log I've pointed at.
- What version of Python are you using
- What version of ICU are you using.

Because all tests that failed actually use Python for testing
or connected to Localization library - ICU.

Also please provide me:

- What version of CMake are you using
- What versions of ICU, zlib, pcre are you using.
- What version of GCC are you using.
- Did you have any warnings?
- Have you had any build faults?

Can you please give me an output of:

   ldd ./proto_test
   ldd ./internal_forwarder_test

I just want to see that everything looks on correct libraries.

> I think cppcms 1.x.x is not yet ready for production ?

1. CppCMS 1.x.x is still on beta stage - but it is slowly becomes
   production ready

2. As you probably expect, 100% of tests are usually passed.

   So if so many tests fail then probably something is wrong with
   build or libraries combination because as you can see according to

   http://art-blog.no-ip.info/wikipp/en/page/cppcms_1x_platforms

   There is quite good coverage of platforms passing these tests.

[Cppcms-users] CppCMS 1.x.x status updates.

[Artyom <art...@ya...>]

Hello CppCMS users.

CppCMS 1.x.x branch is getting closer to beta release,
hopefully at the end of June beginning of July beta version will be
available.

Meanwhile main project's wiki was converted to new CppCMS version
and now runs on top of it, So you may consider wikpp_v100 wikipp branch
as beta version of updated Wikipp.

Best Regards,
  Artyom




      

Re: [Cppcms-users] [shared-hosting] Options for execute cppcms applications

[Artyom <art...@ya...>]

Hello,

First, make sure that your hosting provided supports execution of fastcgi programs written
in C/C++.

About shared libraries:

This maybe tricky, you need libcppcms. library, fastcgi, boost libraries and even some more. Note when you use boost libraries you need to have exactly the same version on hosting provider...

So I'd recommend linking all libraries statically:

1. Compile your own version of Boost.Regex (without ICU), Boost.Iostreams (with Zlib), Boost.Signals.
2. Build cppcms library with --disable-forkcache --disable-tcpcache --disable-sqlite and if you do not use AES encrypted cookies, compile with --disable-crypt
3. Link your application with all libraries statically:

  gcc [hello objects] -o hello /path/to/libcppcms.a /path/to/libcppcmstranstext.a /path/to/libfcgi++.a /path/to/libfcgi.a /path/to/libcgicc.a /path/to/libboost_regex.a /path/to/libboost_signals.a /path/to/libboost_iostreams.a -lz -lrt -ldl -lpthread

You may also want to add -lgcrypt if you use AES encrypted cookies.

Make sure your application links and runs.
Make sure ldd ./hello points only to few system libraries like zlib, librt, libdl libpthread

Now try to upload it to hosting.

Notes: CppCMS is designed to be used on at least VPS where you can actually
install software. Most shared hosting providers do not allow you to use C++ fastcgi
executables.

I'd recommend you to have at least command line access to have an ability to check 
all this.

Regars,
  Artyom


I recommend you linking your application statically with CppCMS. See

Greetings,

How can i execute cppcms applications in shared hosting?
i can't change the configuration of apache and i can't install lighttppd or nginx.
I put the .fcgi file in the directory cgi-bin with permissions 755 (in Linux) and the error is


> error while loading shared libraries: libcppcms.so.0: cannot open shared object file: No such file or directory.

What I can do?

Thanks for your help,

I discovered the problem was the content in the config's files because had
server.socket here and in the lighttpd.conf too.

Re: [Cppcms-users] [lighttpd] How execute many applications

[Artyom <art...@ya...>]

Hi,

What are your's  /var/www/hello-config.txt and  /var/www/ok-config.txt?
Any messages from web server?

Have you tested that your applications run with cppcms_run

cppcms_run -s /hello hello.fcgi -c hello-config.txt

And go to localhost:8080/hello

Few notes:

1.
Make sure that you do not specify server.socket in your configuration
at all so application would know that it should get connections from
standard input given
by server - when the server is responsible on starting application.
2. Make sure your server.api = "fastcgi"
3. Make sure that cppcms was compiled with fastcgi support.
3. Read this: http://cppcms.sourceforge.net/wikipp/en/page/ref_config#server-api

Yes, I need to start many applications (only cppcms in moment).

My configuration is similar:
fastcgi.server    = (
        "/hello" =>
        ((
                "bin-path" => "/var/www/hello.fcgi -c /var/www/hello-config.txt",

                "socket" => "/tmp/hellofcgi.socket",
                "max-procs" => 1,
                "check-local" => "disable"
        )),
        "/ok" =>

        ((
                "bin-path" => "/var/www/ok.fcgi -c /var/www/ok-config.txt",
                "socket" => "/tmp/okfcgi.socket",
                "max-procs" => 1,

                "check-local" => "disable"
        ))
)

I have
server.port               = 81

So, I charge http://localhost:81/ok or http://localhost:81/hello and the pages loading remains (much time) and don't show the message "Hello World" or "Ok".


PD: sorry for my english poor.

What do you mean?

You need to start several not-related CppCMS applications?

This is how I run wikipp and two blogs on my server:


fastcgi.server    = ( 
        "/cppcms/blog" =>
        ((
                "bin-path" => "/path/to/cppblog -c /path/to/cppblog-config.txt",
                "socket" => "/tmp/socket-a",

                "max-procs" => 1,
                "check-local" =>
 "disable"
        )),
        "/newpress/blog" =>
        ((
                "bin-path" => "/path/to/cppblog  -c /path/to/newpress-config.txt",
                "socket" => "/tmp/socket-b",

                "max-procs" => 1,
                "check-local" => "disable"
        )),
        "/wikipp" =>
        ((

                "socket" => "/tmp/socket-c",
                "max-procs" => 1,

You can access post data directly using raw_post_data() member function
of http::request().

  std::pair<void *,size_t> post_data = request().raw_post_data();

And analyze this.

-------------------
BTW Json:

CppCMS 1.x.x supports JSON-RPC as well... You may find an 
example of usage in tests/jsonrpc_test.cpp

Yes, I saw that. But what if I need just the content of the post which
is not "Form" behavior.
For example, sending json object without "message" name for it?
