Razvan,
If I can reproduce it again I will turn on full logs and send it. In the example code that produced the results below (my original post) $avpi(jimmy) was not initialized anywhere, I just used get to print the results. It may be a simple misunderstanding I have about AVPs, as I am learning more about them. I have a long history with SIP (with other software) and with Lua, but am new at opensips and understanding how AVPs work. In previous versions of testing I DID set $avp(jimmy) to a number of string values in both opensips cfg file as well as in LUA. Obviously when I changed the cfg file I had to restart opensips. However, at one point I noticed that I hand multiple opensips instances running - all with the same cfg file, because they had not died when I exited with a Cntrl-C. I did kill -9 all of them before running the test below. When I set the $avp(jimmy) value it would show up as expected (with the value I set it to), but when I changed code to NOT initialize that particular AVP it should up with the "Old_mcDonald" value which I used to set the $avp(bingo). Other AVPs that I did not initialize but printed returned a "nil" value - which is what I would have expected. NOTE that in the example below (original post) that the printout (Output) prints the value of $avp(jimmy) two times. The first time is before I set $avp(bingo) and the value returned is "nil". Then I set $avp(bingo) in Lua, but do NOT set $avp(jimmy) but the value gets changed to the same thing as $avp(bingo). That is what really made me scratch my head! I am a fan of Lua and really like the concept of have the option to use it with opensips. I am willing to do testing and debugging, etc to help make it rock solid. Additionally there are a number of undocumented lua functions that would be good to add to the documentation. For example: * "pseudoVarSet" * "scriptVarGet" * "scriptVarSet" NOTE: It would probably be good to change "pseudoVar" function name to be "pseudoVarGet" to match "pseudoVarSet", "scriptVarGet" and "scriptVarSet" for consistency. :-) Thanks for help.

Hi, James! I am not sure what exactly is the problem, but I have an assumption. When the scenario was failing, where exactly was the $avp(jimmy) first declared? Inside the LUA script? Is it now first declared in OpenSIPS? Is there any chance you could reproduce this issue again in full debugging?

Perhaps it is just something I do not fully understand about AVPs or opensips or the lua implementation. I was able to reproduce it 100% of the time for a while, but now can not - strange! Any thoughts what happened in the original post? ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Gledhill, James Sent: Thursday, June 14, 2012 3:54 PM To: [email protected] Subject: [OpenSIPS-Users] LUA AVP issue? I am testing the Lua module in hopes of being able to use it more later, but am coming across some strange things. Is this the best place to ask about it? If not point me in the right direction. AVP_set or AVP_get (in Lua module) seem to be getting data for/from other AVP(s). I have included enough code from opensips.cfg and the lua file to be able to replicate this problem. It happens 100% of the time.
