Well, in principle, '==' ought to work as it should, too. It's still odd
behaviour, I would agree. 

However, 'ne' and 'eq' are the operators explicitly designed for string
comparisons. '==' and '!=' attempt to make appropriate type inferences
based on the types of the operands, and as one can see, not necessarily
consistently or correctly.

With "eq" it works as it should.

Just out of curiosity, will this yield the same result? 

if($var(teste) eq 'Test') 

?

Subject: [SR-Users] Odd behavior comparing strings

Greetings,

I found an odd behaviour in Kamailio and i would like to know if it's
intentional.

I've made this snippet for showing :


$var(teste) = $null;

if($var(teste) == "Test")
{
xerr("TEST : If returned true");
}

The "if" returns true if the $var is $null or 0.

I'm using the "cmp_str()" now in order to avoid this issue.

Best Regards,

Duarte Rocha
