Sure, I understand, I also work on both Linux and Windows and from
what info I got on the project I imagined that this is the case.
Thanks for taking care of the problems found so far, I'll keep
reporting stuff that I find.

As you understand I'm mostly Linux/Unix developer

so such things are quite hard to catch them for me.

First of all thanks for contributions
they are very important!

Basically I just had no chance to test in on MSVC8 so I published
what I could test. If it works fine I'll add it to the 
supported platforms list (even thou it wouldn't be used in nightly builds and 
tests)

Ok this is good because I hadn't tested it with Apache on Windows.

Few points:

1. Why and how does this work?

   HANDLE shutdownEvent = (HANDLE) atoi(val);
   
   Isn't handle has meaning inside process only? Or it
   can be shared between processes this way?

2. I think there should be better handling of shutdown:

   It should wait for multiple objects because process may
   go down for other reason and the thread should be stopped
   as well.

   BTW: booster::thread can be used for this purpose.

   it should be something like a special class
   that stops its thread in destructor or something 
   like that.
   
   I'll take a look on this.

Actually CppCMS no longer supports external boost and this
is for ABI stability reason - I don't want users
to have programs to fail because he uses boost_1_43 in their
program and CppCMS was compiled against 1_44 or 1_36.

The internal boost is not only subset of boost but rather
renamed version of it (namespace boost -> namespace cppcms_boost)

These ifdefs should go in any case.

Sorry I have one more patch that I forgot about. When running with
apache+mod_fastcgi the application runs in context of
NTAUTHORITY\SYSTEM which can't use CryptAcquireContext the way it's
used by a normal user (so it's failing) see [1] but from the msdn docs
[2] it seems that cppcms should call CryptAcquireContext with
CRYPT_VERIFYCONTEXT flag (see the flag's description).

[Cppcms-users] feedback after testing cppcms svn trunk compiled with msvc2005

[Cristian O. <one...@gm...>]

Hi,

I'm currently testing cppcms from svn trunk compiled with msvc2005 (I
know that the wiki states that only MSVC9 and MSVC10 are supported but
MSVC8 works just as fine).
As a first impression I would like to say that the lib looks really
good. I intend to use it in combination with apache+mod_fastcgi.
After a few days of working with it I found the following issues and I
want to share them with you:
1. The application does not handle shutdown requests sent by
mod_fastcgi; a simple solution would be to add the mechanism used in
libfcgi (the fastcgi client implementation provided by
www.fastcgi.com) see the attached
apache_mod_fastcgi_nice_shutdown.patch - nothe that the implementation
could be improved to use a cppcms thread instead of _beginthread.
2. When trying the hello/form example I was getting an infinite loop
in the application due to the fact that an input stream was tested
only for eof and not for validity see
http_request_infinite_loop.patch.
These two where critical issues that I would like to see solved
somehow in cppcms. The following two patches are just insignificant
improvements:
3. Enable using external boost lib while running cmake configure and
add an extra name for the zlib library on Windows
cmake_permit_using_external_boost_and_zlib_on_win_name.patch
4. This fixes the only code incompatibility I have found on msvc2005
(mscv_2005_compatibility.patch) but googleing revealed that this can
be fixed using a never winsdk so this is only important if upgrading
is not an option
This is all for now.

Ok...

That was really embarrassing as three was a bug in urlencode for long time.

   char c = ...;
   char buf[4];
   sprintf(buf,"%%%02x",(unsigned)c); // <- BUG HERE!

   Together with the fact that I forgot include <cppcms/config.h> to get 
   CPPCMS_HAVE_SNPRINTF so it hadn't used protected version of 

     snprintf(buf,sizeof(buf),"%%%02x",(unsigned)c); 
     // Which is not correct as well, but not crashes.
   
   and finally got buffer overflow...

Fixed in 1631 in CppCMS 1.x.x and in 1632 in CppCMS 0.0.x

P.S. Now I know why Unicode user names didn't worked in Wikipp.... 

Thanks a lot for reporting this bug.

base64_urlencode seems to be working now, but I still experience random (?)

First of all base64_urlencode indeed had a bug, fixed in trunk changeset 1630.

Thanks for reporting this!


I don't see any issues with urlencode filter seems to work.

Also small notice: "escape" is the **default** filter no need to specify it 
explicitly,
if you want to pass the string "as-is" you need to use "raw" filter - which 
bypasses the 

escaping.

[Cppcms-users] urlencode and base64_urlencode filters do not work...

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

Hello,

Referring to the template filters:

http://art-blog.no-ip.info/cppcms_ref_v0_99_1/namespacecppcms_1_1filters.html
http://art-blog.no-
ip.info/wikipp/en/page/cppcms_1x_templates_comm#Variable.with.filters

In my template, all the following filters work as expected:
<% my_var | to_title %>
<% my_var | raw %>
<% my_var | to_upper %> 
<% my_var | escape %>

But if I use one of the two urlencode filters, the application crashes at run 
time:
<% my_var | urlencode %>
<% my_var | base64_urlencode %>

Is their use different?

But I see in wikipp that you don't use any filters for URLs, e.g.:
	<a href="<% c.diff_url %>"><% gt "Diff to previous" %></a>

What's the best (safest) way to handle links?


my_var is a std::string.

Thanks,

Augustin.

First of all I must say that I am not an official Debian Developer, but I want 
to get in touch with official Debian Developers in the near future, to propose 
my package in the official repositories.

I agree I should include the recommended dependencies (ICU and Gcrypt), and I 
will do so in a new version of the package. The reason for not building with 
this dependencies is that lately I was creating a minimal version for an 
embedded device that had no such dependencies.

Ok, in the new version of the package I will consider this. At first I'll put 
these binaries in the package libcppcms1-dev (but I have to review the Debian 
Policy).

I have to review the policy of Debian on this, although it is clear that if the 
library has entity itself, it should be in another package. Another thing is 
that currently is only used in conjunction with CppCMS, and could be separated 
in the future as another package, if necessary.

I really don't know: from what I know, most Debian packagers have their own 
tree with the "debian" directory, and the original software does not contain 
this, but if someone wants to build a Debian package from the latest version of 
the software in the repository, it will be easy if they already have available 
these files directly en the official SVN distribution.

I leave to you the decision on this.

Thanks for your words of support for my work, that encourages me to continue to

See cppcms_run script documentation:

  http://art-blog.no-ip.info/wikipp/en/page/ref_utils#run

It is little bit not updated but you only need to replace -c config.txt with -c 
config.js 

It is very useful for debugging with specific web server.

I understand the security implications.
I was simply looking for something convenient, to use locally on my 
development platform.

The problem is, on a Debian system, apache runs as www-data, 
and even if my app has the group www-data, the group does not have write 
access to the socket, so I still need to sudo to fix it after each compile and 
restart: I was trying to find a way to lazy my way out of this ;)

Never mind about this. I'll find an acceptable solution, both convenient and 
secure.

Thanks.

A.

Re: [Cppcms-users] Problems after upgrading cppcms with booster

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

That's was it!

I usually do:
cmake ..
to install in /usr/local/

But a few months ago, when I just started using cppcms, I may have done an 
install using the prefix /usr.
I deleted everything *cppcms* and *booster* that was installed, and 
reinstalled: it now works.

Thanks you Artyom.

Re: [Cppcms-users] Apache2/FCgi external server: socket ownership problems

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

Hi,

You likely need to run the Apache and CppCMS under same group,
This is very good idea for security reasons.

Now setting the socket to a+w is bad... If you really
want to do this (which I do not suggest)

Put at the main() of your progam 

   umask(0777)

If you can't run them in same group: use TCP/IP sockets.

Re: [Cppcms-users] Problems after upgrading cppcms with booster

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

1. Mare sure you have no two versions installed: For example 

   cmake ..

   would install CppCMS to /usr/local/(lib|bin|include)

   But you may used:


   cmake -DCMAKE_INSTALL_PREFIX=/usr ..

   which would install CppCMS to /usr/(lib|bin|include)

2. Make sure you had headers and compilation scripts installed.
3. Make sure you rebuild your own application from the scratch with
   new cppcms.

[Cppcms-users] Problems after upgrading cppcms with booster

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

I was using a much older version of cppcms (from the temporary branch, before 
it was moved to trunk).

I downloaded from svn a fresh copy of cppcms from the trunk.
cmake ..
make
make test
sudo make install
All without any problem.

But now, my own application won't compile anymore. I deleted the build 
directory of my app, and rebuild from scratch, but I get the following errors: 


/usr/lib/gcc/x86_64-linux-gnu/4.4.1/../../../../lib/libcppcms.so: undefined 
reference to `booster::locale::generator::get(std::basic_string<char,

collect2: ld returned 1 exit status


libbooster.so.0.0.0
and
libcppcms.so.1.0.0
are all properly installed in /usr/local/lib as before, but with today's 
timestamp.


Actually, I had tried to upgrade cppcms earlier, but got a similar error and 
reverted to using the older cppcms.


I added 'booster' to my target_link_libraries() in CMakeLists.txt (it seems it 
was not required in earlier versions of cppcms).
I deleted the build directory and started again...
But now, there are compiler errors about the template object:


Linking CXX executable ../my_app.fcgi
CMakeFiles/../my_app.fcgi.dir/view.cpp.o: In function `void 
booster::locale::message::write<char>(std::basic_ostream<char, 
std::char_traits<char> >&) const':
view.cpp:
(.text._ZNK7booster6locale7message5writeIcEEvRSt13basic_ostreamIT_St11char_traitsIS4_EE[void 
booster::locale::message::write<char>(std::basic_ostream<char, 
std::char_traits<char> >&) const]+0x59): undefined reference to 
`booster::locale::ios_info::get(std::ios_base&)'
view.cpp:

`booster::locale::ios_info::domain_id() const'
collect2: ld returned 1 exit status

where view.cpp is generated by cppcms_tmpl_cc from my template.

[Cppcms-users] Apache2/FCgi external server: socket ownership problems

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

Hello,

I recently finally managed to set up Apache2 with FastCGI, start by the web 
server:
http://art-blog.no-
ip.info/wikipp/en/page/cppcms_1x_tut_web_server_config#Apache..FastCGI..Start.by.Web.Server

I documented the solution to some problems I came across :
http://art-blog.no-
ip.info/wikipp/en/page/cppcms_1x_server_configuration_troubleshooting


Now, I am trying to configure Apache, FastCGI, Independent start for easier 
development.
It's working, but FastCGI has a socket permission problem:
When I start the application, the socket has only write access for my user 
(me) but not for the web server user www-data.
I can fix this easily by chmod a+w the socket.
Is there any way to configure the socket (or config.js) so that by default the 
www-data user has write access to it?


Augustin.

You should use HTTP_HOST variable to get the domain.

See: 
http://art-blog.no-ip.info/cppcms_ref_v0_99/classcppcms_1_1http_1_1request.html#0dc145f6fb337cd352c64a7011bd2142


Then you can extract it with regular expression or something like that.

I would overload cppcms::application::main and set the language there
and the "dispatch" urls as I need.

See for example how wikipp handles this: 
http://cppcms.svn.sourceforge.net/viewvc/cppcms/wikipp/branches/for_cppcms_v100/wiki.cpp?revision=1615&view=markup


Just in your case you should do something like:

    static const booster::regex lang_regex("([a-z]+)\\.tatoeba\\.org");
    void your_app::main(std::string url)
    {
       // set language globally before dispatching
       booster::smatchres;
       std::string domain = request().http_host();
       if(booster::regex_match(domain,res,lang_regex)){
             std::string lang = res[1];
             set_current_language(lang);
       }
       // now execute regular url dispatching.
       cppcms::application::main(url);
    }

   Artyom

P.S.: I also would be glad to hear how does it goes with converting tatoeba.org 
to CppCMS.


      

[Cppcms-users] language specifies in sub-domains

[Baptiste D. <bip...@gm...>]

Hi,

I would like to know how to manage sub-domains with cppcms,
because our sub-domains contain the language of the website
they look like:
    en.tatoeba.org
    fr.tatoeba.org

They are "virtual" sub-domains, just to stock the language.

Do you have any idea to configure cppcms and how can I get the language with urls.

Thanks,
Baptiste

Re: [Cppcms-users] Debian packaging for CppCMS

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

Hello,

First of all this is great contribution!

Few notes or issues I had found in this configuration:

1. I would recommend include by default the recommended dependencies:

   a) ICU - is very important part of the library.
   b) Gcrypt or OpenSSL - I'd recommended gcrypt as it has GPL compatible 
license (unlike OpenSSL)

   There are should be included in default builds as they provide very valuable 
features.

2. May be I do not understand but according to the files it seems to me not 
include:

   a) cppcms_tmpl_cc - templates compiler
   b) cppcms_run - the script for running cppcms applications with different web 
servers easily
   
   I think they both should be either in libcppcms1-dev or in the some package 
like cppcms1-tools

3. I don't know what is the policy of Debian, but wouldn't it be better to have 
libbooster and libcppcms
   as separate packages as, libbooster is very useful outside scope of CppCMS 
and can be seen as
   ABI stable boost subset.

   But this is rather minor and optional thing.


Thank you once again.
Do you want debian build files to be included in the
official SVN distribution.

One additional notice, CppCMS is officially beta version and its ABI is not 
stabilized, however
I do not update SOVERSION as I expect that first official - non-beta release 
would have
SOVERSION 1.

Artyom

[Cppcms-users] Debian packaging for CppCMS

[Mario P. <mp...@us...>]

Hello Artyom,

I attach a tarball of a "debian" directory to put in the source's root 
directory of CppCMS for generate two Debian packages: "libcppcms1" and 
"libcppcms1-dev". With this code, in a Debian system with packages 
"build-essential" and "debhelper" installed, we can generate the CppCMS DEBs 
with the command "dpkg-buildpackage".

I've build the Debian packages for i386 and amd64 architectures for CppCMS 
0.99.5, and can be downloaded from this URL:

http://mpalomo.users.sourceforge.net/cppcms/

I hope to build packages for each new official version of CppCMS, which can be 
found at the URL above. Later I hope to also create packages for other 
architectures, and I also want to create packages of CppDB.

I hope this helps for those who work with Debian or Ubuntu. If you see 
something wrong let me know. Greetings,

Mario
