[sr-dev] Assigning a null value from a $sht to a $var fails after upgrade on master

[Hugh Waite]

Hello,
We are having an issue with PVs after upgrading to the latest master 
(i.e. 4.1.0-pre1) which might be related to the comparison of $null and 0
In our previous version (compiled on 9th October) the following code 
worked. It is using the htable as a DB cache

$var(ip_trusted) = $sht(trusted=>$var(srcip));
if($var(ip_trusted) == $null) {
   /* DB lookup */
   $sht(trusted->$var(srcip)) = $var(ip_trusted);
}

After upgrading, the first line is not working as expected. The htable 
value is null (not assigned), but the $var(ip_trusted) value is assigned 
the value 0, so the check fails.

Is this related to the pv comparison bugfix 
(http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=commitdiff;h=3856e9e81c8410b220b893a0dfe7114bba6bdc0d)?

Certainly something has changed since 9 Oct.

Hugh
