Hi,
I am trying to load db_perlvdb.so module using latest Kamailio branch v5.0.6 with git revision 49bd81ad7856dac9b2efd53597fb1c182de7440b on Debian Wheezy 32bit. The compilation and installation went successful however the module gives following error.
-- May 4 19:03:59 webrtc[8895]: INFO: app_perl [app_perl_mod.c:351]: mod_init(): perl interpreter has been initialized (1525453439.237584 => 1525453439.454432) May 4 19:03:59 webrtc[8895]: CRITICAL: db_perlvdb [db_perlvdb.c:79]: mod_init(): perl module not loaded.

I tried to find module perl.so in modules folder of kamailio installation but there is none. Then i looked through the source code but no success.
After some googling, i found following link which states that perl.so was remained to app_perl.so since v4.x.
I have created a small patch for db_perlvdb.c which corrects this error.

Hi,
Seems there are some serious problems with db_perlvdb. It gives segmentation fault as soon as i set it as db url for any module e.g. acc, sip_trace, msilo and so on.

Hello,
quite a surprise that someone is trying to use this module, I was considering to move it to obsolete repo, because nobody used it for so long and no developer updated it over the time.
The module was still compiling due to some casts, but the DB API was changed in the past and this module was left behind.
I did the update of the API (still some warnings that needs to be taken care), so you can try now with master branch. Maybe it goes on pretty well.
Otherwise I do not have to test or maintain the module, if you want to use it, you have to spend some time with it. I can help fixing bugs when they are obvious in the C code (like API changes) or a proper report is filled, but that's all I can do.
Cheers, Daniel

Thank you very much for you help.
Actually I need to support Elastic Search Engine (ESE) for a large data mining project integrated with Kamailio. The easiest way i thought to achieve that was to use Perl VDB or else i have to write up ESE module for kamailio myself.
I am going to test the changes you did to PERL VDB module and will fix up any minor issues to make it working again. Kindly do not remove it from kamailio repo. I am not expert in Kamailio APIs but have good coding experience with C / C++, so I am willing to provide maintenance and bug fixes for the module with your help on API side if needed.
Also, the new DB API for Kamailio, is there any documentation related to it available online. I want to study it and may be add later on a separate kamailio module exclusively for ESE for better performance and features specific to ESE.
Thank you.

Hello,
for documentation related to the DB API have a look to the src/lib/srdb1 directory. There is a good doxygen documentation in the files available. If you install doxygen you can also generate the documentation HTML files locally which shows additional information about dependency trees etc..
Additionally have a look to the db_mysql module, here you can see how to interact with the generic DB API.
If you have specific questions, just ask here at the development list.
Best regards,
Henning
Great. Many thanks.
I have updated and tested db_perlvdb module (using Kamailio::VDB::Adapter::Describe) and it seems to work perfectly now.
Please find attached two patches which apply changes to both code and documentation of this module. Kindly review and merge them to appropriate branches as mentioned below,
The first patch "*db_perlvdb-kamailio-5x.patch*" is for Kamailio v5.0 and v5.1 branches. Theoretically this patch will work for kamailio v4.x branches too however, since directory structure of kamailio changed since v5.0, so some manual work is required to fix file paths mentioned in patch file.
The second patch "*db_perlvdb-kamailio-master.patch*" is for kamailio master branch.
Thank you.

Hello,
thank you for the patch. Daniel applied in commit 6a152024 already some of the const compile warning changes. But some parts of your patch are still missing, you also improved some cleanup functions.
Could you please re-base your patch against current master and create an pull request at our kamailio github? Its rather easy, just a few clicks given you have a github account.
I noticed that you changed the module README as well - please change the module _admin.xml file instead. The README is autogenerated and should not be changed in a patch.
After that I will have a look to the pull request and can apply the changes.
Best regards,
Henning
Hello,
somehow I missed the email with patches -- I pushed in the morning the commit to fix the warnings I introduced with the patch over the weekend, as I had it in mind to finish those changes, before checking dev list, hopefully not breaking that much your work to avoid wasting too much time to redo patches.
As Henning said, better make a pull request with your improvements, it is easier to review and merge.

Joining the development efforts and taking over the maintenance of db_perlvdb is more than welcome and appreciated!
As for this specific case, do you need to fetch data from Elastic that has to be used inside Kamailio (e.g., passwords for authentication), or just push data from Kamailio to Elastic stack? Maybe giving some specific example of what you need to pass from kamailio To elastic and the other way around would help us provide better hints about what can be used.

Hi,
Basically I want to do both. The main idea is to use Elastic Search as database back-end for msilo module and use its unique capabilities such as full text search over very very large data sets to implement chat history with search, update and delete operations etc.
In my view db_perlvdb module is a perfect test bed to create a prototype for this project and once I have that, i can concentrate on writing a dedicated kamailio module to deal directly with ES and take out the middle layer aka PERL from it.
Thank you.

Joining the development efforts and taking over the maintenance of db_perlvdb is more than welcome and appreciated!
As for this specific case, do you need to fetch data from Elastic that has to be used inside Kamailio (e.g., passwords for authentication), or just push data from Kamailio to Elastic stack? Maybe giving some specific example of what you need to pass from kamailio To elastic and the other way around would help us provide better hints about what can be used.
Cheers, Daniel

Thank you very much for you help.
Actually I need to support Elastic Search Engine (ESE) for a large data mining project integrated with Kamailio. The easiest way i thought to achieve that was to use Perl VDB or else i have to write up ESE module for kamailio myself.
I am going to test the changes you did to PERL VDB module and will fix up any minor issues to make it working again. Kindly do not remove it from kamailio repo. I am not expert in Kamailio APIs but have good coding experience with C / C++, so I am willing to provide maintenance and bug fixes for the module with your help on API side if needed.
Also, the new DB API for Kamailio, is there any documentation related to it available online. I want to study it and may be add later on a separate kamailio module exclusively for ESE for better performance and features specific to ESE.
Thank you.

Hello,
quite a surprise that someone is trying to use this module, I was considering to move it to obsolete repo, because nobody used it for so long and no developer updated it over the time.
The module was still compiling due to some casts, but the DB API was changed in the past and this module was left behind.
I did the update of the API (still some warnings that needs to be taken care), so you can try now with master branch. Maybe it goes on pretty well.
Otherwise I do not have to test or maintain the module, if you want to use it, you have to spend some time with it. I can help fixing bugs when they are obvious in the C code (like API changes) or a proper report is filled, but that's all I can do. Cheers, Daniel
