[OpenSIPS-Users] $ru build and set

[Hiers, David]

Hi folks,
I'm running 1.10 and building a script variable by concatenating the values that I find in $ru as I run through a use_next_gw() loop.  Roughly, the code looks like this:

$var(ds) =  $ru;

while(use_next_gw()) {
        $var(ds) = $var(ds) + "," + $ru;
}

$ru = $var(ds);




It runs along pretty well, and I actually get the contact list that I want in the 302 that I send, but I'm logging some errors.  Here's my debug log that covers the statement $ru = $var(ds):


Xlog statement showing the value of $var(ds) and $ru before executing $ru = $var(ds):

Log output from assignment statement:

Even though the log show that $ru is empty, I send a 302 with the desired 3 contacts in the correct order:


SIP/2.0 302 moved

Server: OpenSIPS (1.10.0-notls (x86_64/linux))

If I remove the  $ru = $var(ds) statement, my 302 has just the last (.134) URI in the contact list and no errors are logged, so it is pretty clear that this statement is the one that is building the final ru and causing all the fuss in the log.

What am I doing wrong?
