The broken pipe warning says that the peer (client - browser) reset the connection
before receiving entire page - probably because it was too big.

Now I don't know what is the bug but it seems that you have some loop here...
or you may got some memory corruption.

[Cppcms-users] URGENT: strange bug ocurring

[<ele...@ex...>]

Hi Artyom,

We've been doing data entry into our software and we've found a strange
bug. But im not really sure how to debug it.

We have not changed any of our code in the last week or so.

Basically what's happening is that we have a list of aircraft parts, and
all of sudden, the whole page started repeating itself untill infinity
(including the HTML DOCTYPE), and there's weird characters all over the
page.

The cppcms logfile is saying this:

cppcms, warning: Failed to write response:system: Broken pipe
(http_response.cpp:279)

but I suppose thats because we have to click the browser stop button to
stop it from infinitely repeating itself.

Any clues?
Petr

Asynchronous JavaScript or Asynchronously mounted CppCMS Application/RPC

   http://cppcms.com/wikipp/en/page/cppcms_1x_application_lifetime

I mean if you mount an application asynchronously than you can't call system from there 
as all I/O would be blocked by system

> via system(..). How can I trigger the calling from thread pool?

See in cppcms::service::thread_pool and cppcms::thread_pool documentation

The asynchronous application (javascript RPC) get the call to execute
a bash script
via system(..). How can I trigger the calling from thread pool?

The problem with message that it is locale dependent.
That is why you can specify some general id you know is constant and unique.

So getting the message is problematic and in fact your implementation contains an error.

As for example if you want to call

   return elements_[i].tr_option;

you need to convert it according to locale (otherwise it by default is converted according to global locale)

If you want to get message according to id you need to pass a locale parameter and even localization domain
to convert it.

  std::string msg(std::locale const &l)
  std::string msg(std::locale const &l,std::string const &domain)

But I think it is bad idea in general...


So it would probably be better to return the booster::locale::message or std::string  like


  bool selected_message_is_localized();
  booster::locale::message selected_localized_message();

  std::string selected_message();  

  bool message_is_localized(int num);
  booster::locale::message localized_message(int num);

  std::string message(int num);

  bool message_is_localized(std::string const &id);

  booster::locale::message localized_message(std::string const &id);

  std::string message(std::string const &id);


And each one of the (selected_)?(localized_)?_message()
would throw an error if the type is not correct

Re: [Cppcms-users] Boost locale with icu backend static linking.

[Stanimir M. <sta...@zo...>]

Sorry for bothering you! It should be my something wrong with my
ubuntu development machine, so i will setup a new clean one and i bet
the problem will disappear. If it doesn't then i will write back
again.

Actually, this looks to be very common problem, i.e. messing up
something bad with multiple installations. That's why i am tring to do
everything in a new virtual machine first, before posting again for
help.

Re: [Cppcms-users] cppcms::service and system(..)

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

Make sure you do not call system from asynchronous application - call it only from thread pool


In general I don't see why shouldn't system work. I have some project that run latex from the application
(even thou not using system but rather using fork+exec)

Bottom line show the code.

Ugh, never write a letter and especially code online, sorry ) (if it possible - please remove last my message from maillist)

"while" in function originally looks like this, but needs in timeout implementation:
while(fgets(buf, MAX_BUFFER, pipe) != NULL) {
  out.append(buf);
}

Re: [Cppcms-users] cppcms::service and system(..)

[kpeo <sla...@ya...>]

Hello,

Fast answer:
system() is not so thread-safe way for calling system scripts. 
E.g., you can use booster::aio::deadline_timer (async_wait method)
or simple "old" pipe-method like this:

# define MAX_BUFFER 1024
std::string vexec(std::string const &cmd)
{
        char buf[MAX_BUFFER];
        std::string out;

        FILE* pipe = popen(cmd.c_str(), "r" );
        if (pipe == NULL ) {
                BOOSTER_LOG(debug,__FUNCTION__) << "invoking " << cmd << " is failed";
                return "";
        }
        while(1) {
fgets(buf, MAX_BUFFER, pipe) != NULL ) {
                out.append(buf);
        }
        pclose(pipe);
        return out;
}

Shure, this realisation needs in implementing of timeout for waiting of answer.

[Cppcms-users] cppcms::service and system(..)

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

Hi all,

I would like to implement a Service class based on cppcms::service. I would like
to trigger the rpc call via java script (works) and in the Service
class I would like
to use system() function to execute a bash script.

If after executing/while executing the system function the cppcms apps
hangs completely.
My Service implements also a RPC call which does a reboot of the
system - which works.

Any idea what could went wrong?

thanks

[Cppcms-users] forms - select_base::msg patch

[kpeo <sla...@ya...>]

Hello all!

Sometimes we need to return a message, attached to selectable widget. 
For example, we have a content structure and form inside it with selectable widget, that has a displayed text (message) for every options.
As i understand, original API can't return a message - just id (int or string). 
Shure, we can use id = message, but what if message is not unique or we need less alphabets for option's storing? We also may want to display this option as message in content structure and store this option as id. 
Well, we can use own component (map or kind of enum) to store id-to-text mapping, but we already have one in original library. 

So, i decide to write this little patch for src/form.cpp and cppcms/form.h.
Shure, you can use it freely at your own risk, as me ;) And i'll be glad to see any criticism about it.

Suggest, may be after reviewing by maintainers and if this patch looks useful - it will be included in new revisions of framework.

kpeo

[Cppcms-users] Boost locale with icu backend static linking.

[Stanimir M. <sta...@zo...>]

Boost locale with dynamic linking works just fine. When i try to link
it statically i get bunch of unresolved externals.

1. I did try with plain icu api call and static linking. Works.
2. I tried a simple libboost_filesystem api call with static linking. Works.

The only problem is when I try to link libboost_locale statically.
Does someone is able to statically link it?

Greetings,
Stanimir

Re: [Cppcms-users] MongoDB and Hypertable support

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

Hi,

You can wrap several document based DBs APis to provide a consistent
familiar interface to
user. Only requirement is that they should return similar sort of data
if not same.

Re: [Cppcms-users] MongoDB and Hypertable support

[陈抒 <csf...@gm...>]

I used CppCMS with MongoDB for several months.
Don't need to wrap it. MongoDB is a document database(or NoSQL database), I
don't think you could get any benefit from wrapping it.

Re: [Cppcms-users] MongoDB and Hypertable support

[Daniel V. <chi...@gm...>]

I am curious.

What is the benefit for wrapping mongodb instead of just using native
mongodb C++ API in cppcms?

Bests.

Because you are not supposed to run wikipp behind internal web server.
It is always recommended to use full web server like Lighttpd, Nginx or Apache.
Internal web server should be used for development and embedded systems only

No, just edit the code :-)

Oh yes! Thank you, that helped. But these two steps are not mentioned on
documentation page.

Is it possible to pass some configuration to the Discount markdown library?
I would like to enable inline HTML and definition lists.

Thanks in advance.

Re: [Cppcms-users] MongoDB and Hypertable support

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

I think as a separation I can put all code in a namespace inside cppdb
like nosql. The problem is that these are not like RDBMS and interface
will have to use individual DBs C++ API. So, to nullify the effect on
existing cppdb I think putting new code in a new namespace should suffice.
Once the wrappers are complete and interface is similar or same we can
go forward or leave it inside the new namespace if interfaces are not alike.

Re: [Cppcms-users] MongoDB and Hypertable support

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

See, technically, if your queries results are tables and data-types are string, datetime, integer, floating point, blob
you can develop your own backend for CppDB. And than do queries like:

  cppdb::session db("mongodb:some-parameter=somevalue");
  cppdb::result r = db << "db.users.find({'last_name': 'Smith'})";
  while(r.next()) {

    std::string first_name = r.get<std::string>("first_name");
  }

But I'm not sure it would be the best approach


Still, if you want to take a look on:
