<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">My original script (3.3.1) contains this sequence :<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> $var(i:rangeInx)=0;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> xlog(" imbxRangeInx value before test : '$var(i:maxRangeInx)' ");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> if ($var(i:maxRangeInx)==$null) {<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> $var(i:maxRangeInx)=99;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> }<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> xlog(" imbxRangeInx after test : '$var(i:maxRangeInx)' ");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:21.3pt"><span lang="EN-US" style="font-family:Wingdings">è</span><span lang="EN-US"> The results are :<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:70.8pt"><span lang="EN-US">imbxRangeInx value before test : ‘0’<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:70.8pt"><span lang="EN-US">imbxRangeInx value after test : ‘99’<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I run the same script on my new server and I get ‘0’ before and after the test.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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) :<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> $var(i:rangeInx)=0;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> $var(toto) = $null;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> if ($var(toto) == $null)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> xlog ("toto true");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> else<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> xlog ("toto false");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The result I got is always ‘toto false’.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">That is a major issue for me and it let me confused about the possibility to move to kamailio 5.0.x.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Have people an idea / explanation, why this issue ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
