Since migrating to sipp 3.1 (from sipp 2.0.1), the old scenario files that used
to work for me now don't. I get the telltale "VAriable referenced 1 times!"
error message and the script terminates.
I looked through this mail list's archives and discovered that there were
checks put into place that cause this error when a assign_to is made w/o using
the assigned variable later on. Unfortunately, I think there's a flaw of logic
here, because if I remove the assign_to statement for the supposedly offending
variable, sipp then complains that I have to use an assign_to for my regexp!
First, I run *with* the assign_to in place:
<recv request="INFO">
<action>
<ereg regexp="tag=[^;]+" search_in="hdr" header="To:" check_it="true"
assign_to="dummy1"/>
<ereg regexp="tag=[^;]+" search_in="hdr" header="From:" check_it="true"
assign_to="dummy2"/>
</action>
</recv>
which results in:
"sipp 172.22.20.55 -sf successful_call.xml -inf clients.csv -l 1 -i
172.22.20.186 -p 5063 -m 1 2008-08-18 10:21:22:392 1219076482.392181:
Variable $dummy1 is referenced 1 times!"
Then I remove the assign_to:
<recv request="INFO">
<action>
<ereg regexp="tag=[^;]+" search_in="hdr" header="To:" check_it="true"/>
<ereg regexp="tag=[^;]+" search_in="hdr" header="From:" check_it="true"
assign_to="dummy2"/>
</action>
</recv>
and this results in:
"sipp 172.22.20.55 -sf successful_call.xml -inf clients.csv -l 1 -i
172.22.20.186 -p 5063 -m 1
2008-08-18 10:22:03:021 1219076523.021795: assign_to value is missing."
I *need* to have that assign_to in there to allow me to do the check_it on the
To: field. Otherwise my test is compromised (I could conceivably get a INFO
that doesn't have a To: field in it).
I think this is a bug. Is it really necessary for sipp to check my variable
usage?? It breaks my existing scenarios.
