debian 6 aws.client.post sll trouble

[björn lundin]

Hi!
I got a debian 6, with
libaws2.10 and gnat 4.6


I try to use AWS.Client.Post on a https-URL but I get this
exception:
 adjust/finalize raised PROGRAM_ERROR: SSL not supported


I've only installed via apt-get, no programs/libs are compiled onto this system.
Is there a simple way of getting SSL support here ?

code as :

    Aws.Headers.Set.Add (My_Headers, "X-Authentication", My_Token.Id);
    Aws.Headers.Set.Add (My_Headers, "X-Application", Token.App_Key);
    Aws.Headers.Set.Add (My_Headers, "Accept", "application/json");

    Answer := Aws.Client.Post (Url          =>  "https://api-ng.betstores.com/betting/betfair/services/beta-api.betfair.com/betting/json-rpc",
                               Data         =>  "[{'jsonrpc': '2.0', 'method': 'SportsAPING/v1.0/listEventTypes', 'params': {'filter':{}}, 'id': 1}]",
                               Content_Type => "application/json",
                               Headers      => My_Headers);

    --crash above

    Log(Aws.Response.Message_Body(Answer));


thanks

This means that AWS was not compiled with SSL support on GNU/Debian.
You'll probably have to build yourself from source.

Hmm, I was hoping not to have to do that. 
I'll try this weekend.
Thanks Pascal

ok, uninstalled the debian pre-packaged, 
and installed from source, editing makefile.conf

Seems to work :-)
But I am a bit surprised that AWS on Debian is not packaged with ssl enabled by default

Thanks

That's because the OpenSSH license is incompatible with the GPL that AWS
uses, see /usr/share/doc/libaws2.10.2-dev/README.Debian, which I
reproduce here for your convenience:

Ada Web Server for Debian - maintainer's notes

The Ada Web Server library  can use either libopenssl or libgnutls for
strong  cryptography.  This enables  support for  the HTTPS  and other
encrypted  protocols.   Unfortunately  there  are problems  with  both
libraries.

libopenssl  is  licensed under  terms  incompatible  with the  General
Public License,  while libaws is  licensed under the  GPL.  Therefore,
Debian cannot ship binaries of libaws linked with libopenssl.

Linking libaws with libgnutls has  a technical problem which I haven't
been able to correct.  The  symptom is that both ada2wsdl and wsdl2aws
segfault during  elaboration.  The  segmentation fault takes  place in
the call to gcry_control which is at aws-net-ssl__gnutls.adb:1000.

If you would like to help solve this problem, please send email to
aws@lists.adacore.com (I'm on that list, so you don't need to CC me).

Thanks for the explanation, I understand now, and it makes sense.

I've built AWS (git revision 4cb349e5d3514ba8b37df08af8b936098926e9a2
from 2013-06-10) with libgnutls-dev (Debian/wheezy package version
2.12.20-7) for use with Alice.  It seems that I didn't enable building
"ada2wsdl", but "wsdl2ada" works well enough to print usage instructions
on standard output.

I think there should be hope for a SSL/TLS enabled AWS package for the
next version of Debian.

Greetings,

Jacob

Hmmm...  Well...  Maybe...  (Now that I think about it, I did that build
with GNAT GPL 2012, so it is not certain that it will work with the
Gnu/Debian version of GNAT.)

Indeed GNU/TLS will be neat to have fully supported. I have been playing
with this since some time, it is *almost* working fine but seems to
heavily depends on the GNU/TLS version.

If someone with good knowledge on GNU/TLS want to have a look it will be
really nice. At this point I feel that we are almost ready for making
GNU/TLS first class citizen and make this SSL layer the default...
