[Cppcms-users] Session Load and Save events

[Joseph A. <jsa...@gm...>]

Hi Artyom,

I have been tinkering with CPPCMS in the last few weeks after its discovery
and I must say it is a wonderful work from you. It has a great potential as
a highly scalable and light-weight web server application. I have a set
C/C++ libraries which has so far no face and I would like to use CPPCMS to
build a WebAPI face for them. So I thank you very much for contributing a
such a great useful product.

My question is, within the web application process, how I do I get to know
when a session is loaded and when the session is saved (to the file or other
persistence options you have provided). Session interface currently exposes
"save" and "load" methods. It also allows us to set an expiration policy
which enables the session to expire when it is idle.  But how the web
application process will be notified of such events as Session::Load and
Session::Save in order to employ some critical operation such as updating a
table in the database about when a user's session started and terminated ?

Your advice is greatly appreciated.

Joseph.

The most important task I really need to implement is

http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Add.Support.of.multiple.event.loops


Because it is critical for scalability 

Also this one: http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Provide.Plugin.Framework

probably would be postponed - mostly because it requires some design and there is already some basic support of it + support in cppcms_tmp_cc that is ready.

And several other small tasks that would not take much time:

http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Improve.Support.of.RESTful.services

http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Improve.file.serving.performance

Also I'm planning to publish some notes about the project state.

>Btw did you see http://sourceforge.net/p/cppcms/bugs/104/ ?

Yes. See it is a bug in CMake. You can extract tar.bz2 using 7zip without problems.

The problem is that zip can't contain symlinks - and some people would try to download
it anyway even on Linux and will get failed tests.

So I'd rather prefer not to provide zip.

[Cppcms-users] Current state of development

[Christian G. <chr...@gm...>]

Hi Artyom

It looks like you are quite a busy man but what are the plans for a new cppcms
release?

If I read http://cppcms.com/wikipp/en/page/cppcms_1x_tasks it looks
like that there
are quite a few (open?) tasks. Would it make more sense to strip down the number
of planed features and release more often a new version?

Btw did you see http://sourceforge.net/p/cppcms/bugs/104/ ?

Re: [Cppcms-users] UnitTest

[Klaus W. <kjw...@ya...>]

Hi Sab,

I too found it useful to test against the application directly and took 
a leaf out of Artyom's tests, namely tc_test.cpp and the related 
dummy_api.h. I attached the cpp file. Feel free to start from there and 
to deliver feedback.

Cheers!

[Cppcms-users] Destruction of session

[Forgotten O. <dr...@gm...>]

Hello,

Is there a way for you to know if a session is actually being destructed
due to timeout if server side session is used?

Or do you have to keep track of this and issue a
cppcms::session_interface::reset_session() ?

Thanks.

Regards,
Mikhail

Yes, but not with CGI - use FastCGI or SCGI :-)

Lighttpd :-)

Seriously, any web server like Apache, Lighttpd, Nginx or Cherokee is fine.

But.. Apache is very powerful but does not scale well for multiple connections.

For example one one of the heavily loaded cppcms/lighttpd based sites we keep
file descriptor limits much higher that default 1024. The apache even in
mod_worker would use huge amount of memory for such a load - if it would be capable
of handling it a tall. While lighttpd virtually does not feel it.

So the actual choice is between lighttpd and nginx (or Cherokee).

My personal preference is lighttpd, but nginx is fine as well
as long as you use latest versions >=1.3.*

http://blog.cppcms.com/post/99


Also many would disagree about my opinion about nginx.

I would think nginx is a better choice.

So...
In production system for e-commerce using cppcms, your advice is to use a
webserver and running the cppcms app in cgi ?

If so...

Apache or nginx ?

Re: [Cppcms-users] upgrade_lock and upgrade_to_unique_lock are not implemented in BOOSTER

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

Upgrading a lock from shared to unique can't be done in atomic way. It can't be done using POSIX API and it can't be done in Boost as well (see docs about upgrading).

So if you want to upgrade the lock - just release shared lock and acquire unique one and of course be aware of the state that can change on between.

So booster does not implement it as it is not really that useful.

Re: [Cppcms-users] cppcms standalone really?

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

It is simple:

- Internal web server is good for development and if is fine for embedded applications.
- It is not very efficient in serving static files
- It does not support many features of modern web servers, including SSL, vhosts etc.
- Internal web server supports HTTP/1.0 responses only

[Cppcms-users] upgrade_lock and upgrade_to_unique_lock are not implemented in BOOSTER

[CN L. <cn...@gr...>]

Hi!
I am trying to use boost::upgrade_lock and boost::upgrade_to_unique_lock as explained by Dalle in
http://stackoverflow.com/questions/989795/example-for-boost-shared-mutex-multiple-reads-one-write
---begin example code---
void conditional_writer()
{
boost::upgrade_lock< boost::shared_mutex > lock(_access);
// do work here, without anyone having exclusive access

if (something) {
 boost::upgrade_to_unique_lock< boost::shared_mutex > uniqueLock(lock);
// do work here, but now you have exclusive access
}

// do more work here, without anyone having exclusive access
}
---end example code---
It appears that upgrade_lock and upgrade_to_unique_lock are not implemented in booster. Would someone please point me to the alternatives/workaround?

CN

`dispatcher().assign()`. But  what is the job of `mapper().assign()` ? even
if I comment that out it works.

In documentation it says

> we create a name for this part called "number" and we provide a URL
> formatting pattern /number/{1} - the opposite of regular expression
> where {1} is a placeholder for the first parameter for formatting the
> appropriate URL.

But why create *a name for the part* and why its necessary ?

    hello(cppcms::service &srv): cppcms::application(srv){
        dispatcher().assign("/number/(\\d+)",&hello::number,this,1);
        mapper().assign("number","/number/{1}");

        dispatcher().assign("/smile",&hello::smile,this);
        mapper().assign("smile","/smile");

        dispatcher().assign("",&hello::welcome,this);
        mapper().assign("");

        mapper().root("/hello");
    }

[Cppcms-users] cppcms standalone really?

[Eric G. <con...@gm...>]

Hi,

I am interested to create a website with cppcms.  I need authentification
and probably ssl.  I want it faster as possible...  and I love C++ !

I have some questions, to be sure...

I think cppcms can run without any webserver.  What I think I saw with the
hello world example.  Is it correct that I can run it without Apache or
nginx?  If so... what could I need later that I won't be able to do if my
site run directly without webserver?

If I run my site without webserver, will it be ok for a lot of concurrent
users?  Or maybe the ability to run directly is limited to embeded devices
or single user site ?

Somebody know how faster is it comparing "standalone mode", running in
"apache" and/or running in "nginx" ?

Thanks for infos.

E.

Re: [Cppcms-users] make error during installation

[Themistokles K. <thm...@gm...>]

I had the same problem with cppcms-1.0.4 and fixed it by installing manually
the latest version of the ICU library(v51.2) (ubuntu came with version 4.8).
It compiled ok, although it failed two tests:
85 - test_locale_boundary (SEGFAULT)
86 - test_locale_formatting (Failed)

could you format the source please? I see nothing wrong atm. What do you
mean with matching (which?) url/tmpl file? You should be able to see
your page at localhost:8080/
It seems like it's the messageboard example, isn't it? See what you have
changed and do that until you find an error.

Re: [Cppcms-users] Intionalization method call raises exception

[CN L. <cn...@gr...>]

The exception appears to be caused by passing invalid value to parameter "locale_name":
service().generator().generate(locale_name);
I am still trying to figure out why
_("LANG").str(service().generator().generate("zh_TW.UTF-8"));
never succeeds in translating.

Re: [Cppcms-users] Needed Guidance

[Shiv S. D. <shi...@gm...>]

It is not a good idea to run CppCMS as root. You should run your FastCGI 
spawner with the same user name as nginx. Then all should be fine.

I have assumed that you are using FastCGI.

Respect,
Shiv

[Cppcms-users] Needed Guidance

[David Y. <com...@gm...>]

Hi all,

I am a newbie on cppcms.
I am convinced of cppcms vision is being faster, leaner and greener web
solution using C++.

I am trying to setup my VPS using the links found and setting a nginx
server in debian wheezy.

http://cppcms.com/wikipp/en/page/cppcms_1x_tut_web_server_config#Nginx
http://cppcms.com/wikipp/en/page/ref_utils#run

Make and Build cppcms/examples/hello_world
cppcms_run hello -c config.js

Well, I got a 502 Bad gateway error.
In nginx.log, there is a permission denied on the socket.

I am running cppcms_run as root, but the nginx worker thread was default to
user nobody.
I attempted to set /tmp/hello-fcgi-socket with 777 and chown nobody to no
avail as
cppcms_run will always change the file attributes of the socket file.

I tried to configure the preloaded cppcms.... nginx.conf with "user root"
or "user nobody",
but the nginx.conf file will be updated with a fresh settings again.

Hope that somebody can advise how to solve this issue.

Thanks!

David Yew

No, THEY ARE NOT.

In async app you need to use response from the event loop
and in synch app from the thread executing the request.

If you want to do something in thread pool post a job to the thread pool, from the pool post a job
to event loop with the results and **than** use the response().
