[OpenSIPS-Users] OpenSIPS 3.0.2 - 'IF' statement doesn't evaluating correctly

[Igor Pavlov]

Hi all, I have found the strange behavior of evaluating boolean value in
'if' statement. Here is the part of my routing script, it handles the BYE
msg (I removed real logic and left only xlog).

if ($DLG_lifetime < $dlg_val(dialog_min_time)) {
    xlog("L_DBG","[$ci] Dialog lifetime less then dialog_min_time ;
duration: $DLG_lifetime ; $dlg_val(dialog_min_time)");
} else {
    xlog("L_DBG","[$ci] Dialog lifetime greater then dialog_min_time ;
duration: $DLG_lifetime ; $dlg_val(dialog_min_time)");
}

The '$dlg_val(dialog_min_time)' setup during INVITE handling, after
create_dialog().

Under load I see that '$DLG_lifetime < $dlg_val(dialog_min_time)' is not
evaluating correctly. Here is some logs:

opensips[1589]: [56276459-0-1637911800 at 1.1.1.48] BYE from 2.2.2.143:5060,
dialog_min_time: 30, duration: 161, status: 5
opensips[1589]: [56276459-0-1637911800 at 1.1.1.48] Dialog lifetime less then
dialog_min_time ; duration: 161 ; 30

Here is DLG_lifetime = 161 and $dlg_val(dialog_min_time) = 30 (161 < 30 ???)

Another example:

opensips[1590]: [58514636-0-1638386270 at 1.1.1.48] BYE from 1.1.1.50:5060,
dialog_min_time: 15, duration: 1212, status: 5
opensips[1590]: [58514636-0-1638386270 at 1.1.1.48] Dialog lifetime less then
dialog_min_time ; duration: 1212 ; 15

Here is DLG_lifetime = 1212 and $dlg_val(dialog_min_time) = 15 (1212 < 15
???)

My OpenSIPS version is:
