Re: [SR-Users] Important problem with this test : if ($var(i:maxRangeInx)==$null)
Hi,
Great thanks to answer so quickly.
I tested the $vn ….in the 5.0.x script instead of $var…., and the results look
good.
So I have to review the entire script to change all the ‘$var…. == $null’
entries to ‘$vn…. == $null’. I assume I have to do the same for the ‘!= $null”
case. Am I correct ?
Now regarding my old kamailio 3.3.1 script, I notice that the ‘$var…. == $null’
works fine but no more with kamailio 5.0.x . So It’s something that has changed
more recently. The 3.3.1 cookbooks doesn’t reference a ‘$vn’ variable.
But may be I misread it.
So if you have comments on this for my understanding, that would be fine.

Hello,
$var(...) don't hold null values, they start initialed to 0 and they are reset
to 0 (when assigning $null to them) -- this is the design from the beginning
which brings benefits in many situation when one doesn't get a chance to init.
If you want a similar variable that works with null, then use $vn(...):

My original script (3.3.1) contains this sequence :
$var(i:rangeInx)=0;
$var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange");
xlog(" imbxRangeInx value before test : '$var(i:maxRangeInx)' ");
if ($var(i:maxRangeInx)==$null) {
$var(i:maxRangeInx)=99;
}
xlog(" imbxRangeInx after test : '$var(i:maxRangeInx)' ");
==> The results are :
imbxRangeInx value before test : ‘0’
imbxRangeInx value after test : ‘99’
I run the same script on my new server and I get ‘0’ before and after the test.
I attempted another kind of test to try to figure out where the problem is. So
I write the simple test (with kamailio 5.0.x) :
$var(i:rangeInx)=0;
$var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange");
$var(toto) = $null;
if ($var(toto) == $null)
xlog ("toto true");
else
xlog ("toto false");
The result I got is always ‘toto false’.
So it appears to me that the test ‘== $null’ doens’ that gives a good result
with kamailio 3.3.1, doesn’t return the same with kamailio 5.0.x.
That is a major issue for me and it let me confused about the possibility to
move to kamailio 5.0.x.
Have people an idea / explanation, why this issue ?

[SR-Users] Important problem with this test : if ($var(i:maxRangeInx)==$null)
Hi,
I'm continue my job to 'migrate' my 3.3.1 kamailio.cfg script on a RHEL 6.2
server to the 5.0.x kamailio version on a RHEL 7.1 server, and I encounter a
major problem with the '== $null' test in the script.
My original script (3.3.1) contains this sequence :
$var(i:rangeInx)=0;
$var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange");
xlog(" imbxRangeInx value before test : '$var(i:maxRangeInx)' ");
if ($var(i:maxRangeInx)==$null) {
$var(i:maxRangeInx)=99;
}
xlog(" imbxRangeInx after test : '$var(i:maxRangeInx)' ");
==> The results are :
imbxRangeInx value before test : '0'
imbxRangeInx value after test : '99'
I run the same script on my new server and I get '0' before and after the test.
I attempted another kind of test to try to figure out where the problem is. So
I write the simple test (with kamailio 5.0.x) :
$var(i:rangeInx)=0;
$var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange");

else
xlog ("toto false");
The result I got is always 'toto false'.
So it appears to me that the test '== $null' doens' that gives a good result
with kamailio 3.3.1, doesn't return the same with kamailio 5.0.x.
That is a major issue for me and it let me confused about the possibility to
