[OpenSER-Devel] error messages in log

[Dan Pascu]

I have these messages in log:

core:do_assign: no value in right expression
core:do_assign: error at line: 246

They appear everytime I have something like this in my script:

$avp(s:some_var) = $hdr(some_header);

and the header is missing.

IMO, those messages should be moved to debug level, because it makes no 
sense to have to write every such statement as:

if ($hdr(some_header)) {
   $avp(s:some_var) = $hdr(some_header);
}

when it can simply leave the avp unset (do nothing) if the right side is 
missing. Maybe it makes sense to see such errors if the right side is 
another avp/var, that wasn't yet set, to detect programming errors, but 
it makes no sense when the right side is a (potentially missing) header.

The end result of the operation is right (i.e. $avp(s:some_var) will be 
null after this), only the messages appear in log everytime the header is 
missing.
