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,

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.
