Yes, it was in 1.5 and it was really handy.
ok, I will add that to the missing compat list to sort out.
The modparam("pv", "varset", "true=i:1") seems to do the trick. It is an extra line in the config but seems to be fine.
Anyhow we can add $true that will return integer 1, as well as $false if people find them useful, it is something trivial.
Cheers, Daniel
Thanks, Ovidiu

How about defining a new PV: '$true'. If we have a constant word in the while loop, then yes, it might be a missconfiguration and it is good to have the warning. Having a '$true' PV will mean that we want an infinite loop and there's no need to print the warning. The '$true' will make the config more easy to read as opposed to defining a variable just for the purpose of creating an infinite loop.
never used the while (true) loop, was it in 1.5? If yes, we can wrap the warning log in #!KAMAILIO compat mode.
An optimization to Andrei's suggestion is to init the true var at startup, to avoid assignment every cfg execution:
modparam("pv", "varset", "true=i:1")

If I define an infinite loop like this: while( true ) { ... } the following warning is reported: WARNING:<core> [cfg.y:3307]: warning in config file /etc/kamailio/kamailio.cfg, line 4, column 9-12: constant value in while(...) The config file used for testing: #!KAMAILIO
route{ while( true ) { exit; } exit; }
How can I define a simple infinite loop without getting a warning in the logs.
I don't want to define a variable just for the while loop and test it. $var(true) = 1; while ($var(true)) { ... }
Is there a specific PV like '$null' or a specific keyword?
No, you have to live with the warning. In most cases infinite loops are a bug and hence we better have the warning (this is a sip router and not a general programing language).
