as a concrete example, how can i figure out if request uri userpart
exists?
i tried to test if len of $rU is 0, but got 1:
$rU = null;
xlog("L_INFO", "Request URI <$ru>\n");
if ($(rU{s.len}) == 0) {
xlog("L_INFO", "Length is 0\n");
}
if ($(rU{s.len}) == 1) {
xlog("L_INFO", "Length is 1\n");
}
prints to syslog
Jul 9 13:27:54 localhost /usr/sbin/openser[16006]: Request URI <sip:test.fi>
Jul 9 13:27:54 localhost /usr/sbin/openser[16006]: Length is 1
which is still the bug that i reported a while back.
I applied now the same fix as in devel to 1.2 -- if PV is null, then no
transformation can be applied.
The issue comes because no coherent implementation was found so far for
PV and NULL, perhaps we should start a public discussion to see what is
the best solution out there. If you have some ideas, please bring then up.
Cheers,
Daniel
