That's it!
Thanks a lot.

Do you think it would be useful for me to add something about this in the 
wiki?
If you wish, I can create a page in an appropriate place to document such 
newbie gotchas.

Re: [Cppcms-users] Can't catch signals after service::run()

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

By default, when the SIGTERM is sent to the application, the cppcms::run() exits and you can perform any cleanup you need.

No need to do anything special.

The situation described in wiki is for reloading (i.e. restarting the service rather than exiting the full program)

Re: [Cppcms-users] How to format readable date from unix timestamp within template?

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

The problem with this clode

 std::ostringstream buf;
 app()->render(std::string("my_skin"), std::string("book_page"), buf, c);
 cp->rContent = buf.str();

is that buf does not have a locale object associated with it.

You need to add following line

buf.imbue(app()->context().locale());

i.e.

 std::ostringstream buf;
 buf.imbue(app()->context().locale());
 app()->render(std::string("my_skin"), std::string("book_page"), buf, c);
 cp->rContent = buf.str();

The response().out() - the default output already has a locale embedded in it.
when you create a generic std::ostream you need to imbue application
specific locale (even if it is default system locale) to make various localization
related tools to work.

 Thanks for your reply, Artyom, as always.
 
 
 For my locale, I have in config.js:
         "localization" : {
                
 "locales" : ["en_US.UTF-8"],
         },
 I have not yet specifically studied locale and translations.
 For the time 
 being English is hard coded in my application.
 
 
 That particular piece of template is rendered thus:
 
 
 namespace content {
 struct book_page : public cppcms::base_content;
 }
  
 void view_book::render_main_content(content::page* cp) {
   content::book_page c;
   // ... snipped parts where I add content to c,
 including r.date_returned.
 std::ostringstream buf;
 // app() returns a pointer to my class myApp : public
 cppcms::application;
   app()->render(std::string("my_skin"),
 std::string("book_page"), buf, c);
   cp->rContent = buf.str();
 }
 
 I have simplified the code above. Hopefully, I have not
 removed anything 
 relevant.
 
 The wiki page about template filters is pretty long:
 http://cppcms.com/wikipp/en/page/cppcms_1x_templates_comm
 Do you think I should complement it by setting up a separate
 wiki page about 
 best practices for rendering times and dates?
 
 
 
 Thanks,
 
 augustin.

Re: [Cppcms-users] Can SSL be bolted onto cppcms?

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

I think it's only about embeded webserver.

Of you use another webserver that support ssl, your cppcms app will support
ssl...  Your app won't see a difference since all ssl process will be done
via your webserver.

[Cppcms-users] Can SSL be bolted onto cppcms?

[Ross R. <ros...@gm...>]

Hello,

I notice that SSL connections are still a TODO on this page:
http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Implement.HTTPS.support

In lieu of the implementation of that task, is there a way to bolt on
SSL using some other program to tunnel HTTP through SSL?  If that were
possible, would it just as good?

[陈抒 <csf...@gm...>]

Using Nginx with CppCMS together is simple, for me, I always use them and
FastCGI protocol. Don't know my way is simplest or not because I did't try
other web servers.
I choose CppCMS because its high performance, and Nginx has high
performance too. So from my angel, Nginx is the best web server for working
with CppCMS.

[Cppcms-users] Is ngix server the easiest way with Debian for cppcms?

[Szilágyi Z. <zol...@ya...>]

Hi,

Anybody could help me with Lighttpd FastCGI under Debian? I found out that I need to installl  lighttpd-mod-fastcgi. I cannot found deb package for it (or repository). I found :redhat/fedora/centos -  yum install lighttpd-fastcgi
www.fastcgi.com site right now it is not working.

For SCGI with synaptic package manager I  find nginx-full.Should  I go rather with ngix and SCGI, (no fastcgi support)?
 Or should install Apache? (On Windows I had painfull and time waist full experince with apache + fastcgi module, I blame fastcgi(but it can be lack of knowledge), without successs), but perhaps on linux it would be easyer, but I guess rather would try something now  like ngix, rather (not) having so  long  ride with fastcgi.With synaptic package manger I find only libapache2-mod-scgi module  anyway.


I just  want to try out hello world example, but without web server it is not working. Ok, I reformulate my question:  witch webserver under Debian you think it would be the easiest for a newbies to install and configure  for the  hello world example.

(Why neeed 3 layer arhitecture: for example lighttpd + fastcgi + cppcms? I  would not be  better if fastcgi and  SCGI, protocol would be implemented in cppcms?)

Best regards,
Zoltan

It actually should work....

How do you render the template?
What are the locale settings?
Do you render to a stream that isn't the respone().out()?

The only point I can see that this isn't working is that the stream you 
are rendering into is missing the locale configuration.

[Cppcms-users] How to format readable date from unix timestamp within template?

[augustin <aug...@ov...>]

Hello,



How to format  a readable date from a unix timestamp within a template?

I thought it would be something straightforward to do but I seem to be stuck.
I've spent a fair amount of time reading the API documentation, the cppcms 
wiki, and code examples found in cpp blog, but the only thing I ever get 
displayed within my application is the unix timestamp itself.

I have tried all of the following within my .tmpl file, but none of them 
actually filter the timestamp:

r.date_returned is a time_t unix timestamp.

<% gt "{1,datetime=s}" using r.date_returned %>
<%= r.date_returned | date %>
<%= r.date_returned | strftime("%d/%m/%Y") %>



What am I missing?


thanks,


augustin.

Re: [Cppcms-users] per request data storage?

[陈抒 <csf...@gm...>]

You want to use cppcms session with mysql & cppdb. also using static
linking.
I have not used this way before.
Let's see who can give you correct.

i am already using cppdb with mysql which you can link statically, but
maybe i did not understand this right? When i look at session docs, it
says session.server.storage can have the values:

files
memory
network
external

So i assume i need to use external when i want to use cppcms session?
Which seems to be limited to dynamic linking, or am i missing something?

Kind regards,

Re: [Cppcms-users] per request data storage?

[陈抒 <csf...@gm...>]

Hi, Shiv,
  If Heiko uses in-memory database, that means he still enables session in
web server. The web server cannot be clustered unless Redis provides a way
to sync their data in different machines.

And my current project is using MongoDB, mongodb driver can be statically
linked in my app. So when deploying my app on product server, no mongodb
driver's dll or so file is required.

Hi, Heiko:
  If you have chosen a database already and don't want to change this,
could you find a way to link the database client lib into your app
statically?

Re: [Cppcms-users] per request data storage?

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

You can use something like Redis for this which is in-memory database.

Re: [Cppcms-users] per request data storage?

[Heiko I. <hi...@93...>]

Hi,

well, thats exactly the point, i am not storing the session in a
database and therefor i do not want to save things like user password in
the browser cookie.

using a database for session storage would definately be an option, but
as far as i see, this involves dynamic linking, i do not want this, when
my project is near to finish, i will get a commercial license and link
everything into a single file, having some extra files in the filesystem
is not an option.

any way to implement db session without dynamic linking?

Kind regards,
Heiko

Re: [Cppcms-users] per request data storage?

[陈抒 <csf...@gm...>]

1. You can save a key-value data structure in singleton application object,
key will be user id, value can be any user-specific data.
But if you do this, you actually implement your own version of user
session. Why not use cppcms session?

2. If the web server has session, it's not stateless anymore. When
clustering several web servers together to do load balance and to prevent
single point of failure, sync these session between these web servers are
important and hard job. So my way is to avoid use session, just use
database cluster or cache server to hold session values.

Re: [Cppcms-users] per request data storage?

[Heiko I. <hi...@93...>]

Hi,

thanx, i thought about singleton, but wouldn't this be application wide?
So if i store user information in a singleton, everyone would count as
that user?

Kind regards,
Heiko

Not sure the different locations mean what? Different web URLs?
If you want to save something in web app, in my way, I usually create a
singleton object called my_app, you could use any singleton technology to
create it. And save the variables that you want to cache and share  as the
my_app object's member variable.
For multi-thread protection, use boost::mutex to protect them.

Re: [Cppcms-users] per request data storage?

[Heiko I. <hi...@93...>]

Hi,

hm.. maybe i'm missing something here... i do not want to store full
user information in the session cookie, i just want to safe it somewhere
for the current request, so i do not re-re-re-re-read it from the
database, just because i need it on 5 different locations.

i already have a cookie session running, but it only holds the user id
and a usertoken.

What i would need is some storage, that is neither file/cookie based and
does not interfere with the session.

Pretty much like some local variables in the actual application instance,
but on a point where i do not have this application instance.

Is something like this available, or do i have to give the application
instance as parameters to every function that might need information
limited to the current request?

Maybe i'm just thinking too much php here ;)

Thanx in advance,
Heiko

 Hi there,
 
 how can i save data per request?
 
 I store the user id in a browser cookie, then there is a
 function
 called getCurrentUser() which looks into the cookie, then
 gets the user from the database.
 
 Obviously i do not want to have a database query every time
 getCurrentUser() is called within one request, so i want to
 store the current user for the current request.
 
 How can i do this?
 
 Thanx in advance.
