Given this code in .cfg:
if (!perl_exec("verify", "route_LOCATION")) { xlog("L_INFO", "Invite verify failed for ruri: $ru\n"); sl_send_reply("403", "Not Allowed"); exit; }
if the perl function returns 1 everything proceeds nicely (skipping the if block as as expected).
But should the perl function return 0 (which seemed like the right choice for failure) the call fails to progress; the if block does not run, and nothing else does either. The INVITing sip client retries and times out.
I had to return a negative value to get the if block to run.
Expected? Or bug?

The return codes have a special interpretation in the config file:
* >0 - is true * <0 - is false * =0 - exit config file execution

I guess perl_exec() returns what is returned from the perl script.

Ah. I didn't find that.

Thanks for that pointer; most interesting!

Yes.
The -/0/+ distinctiong nicely makes things easier for what I want to do.
Thanks,

This evaluation is from the beginning of ser back in 2001, some notes were in cookbook:
http://www.kamailio.org/wiki/cookbooks/4.1.x/core?&#return
I added an entry in the faq to be easier to find:

About a decade ago I'd have known/remembered that. But I've mostly been doing development (on other code bases) since then and am only now getting re-familiarized while implementing a new distriuted cluster.

Good idea.
