Re: [asterisk-users] Forking AGI or GoSub

[John Runyon]

Glancing at the code, Asterisk appears to wait for the pipe between
Asterisk and the AGI to be closed before it considers it completed. So, the
problem is this pipe is duplicated into the child.

Try adding this after setsid:
fclose(STDIN);
fclose(STDOUT);
fclose(STDERR);
fopen('/dev/null', 'r'); // set fd/0
fopen('/dev/null', 'w'); // set fd/1
fopen('php://stdout', 'w'); // a hack to duplicate fd/1 to 2

In PHP something like:

if ($pid != 0) {
// we are the parent
// do parent stuff
exit;
}

// we are the child, detatch from terminal
$sid = posix_setsid();

Dovid,

I'm not much of a PHP person, but in perl, i check the process id that's 
returned from fork() and exit if it's 1 (parent) and keep processing if 
it's the child (greater than 1).


I think php uses pcntl_fork().

Re: [asterisk-users] Forking AGI or GoSub

[Michael Munger]

I am very much a PHP person. PHP doesn't really have an elegant way to handle 
forking / threading, which can make it non-trivial to implement and can be 
unreliable if the implementation is not exact. PHP must also be compiled to be 
thread safe in order to do this properly.

Granted, the last time I looked into this with PHP was under PHP 5.6, and tests 
at that time did not yield the results we wanted. We ultimately moved to Python 
when we needed multi-threading, which is extremely elegant and reliable for 
this application.

Re: [asterisk-users] Forking AGI or GoSub

[Michael Munger]

What’s the purpose of the URL? Does it assist operators who handle the 
emergency services call?

Off the top of my head, I am not sure you can fork an AGI call from asterisk. 
Seems it would defeat the purpose of AGI, which should handle the call flow 
when it has control of the call. Have you considered have the AGI write to a 
socket of a secondary application, which will then perform the web call from 
its own process?

Seems relatively simple to write the call information to a socket as it’s 
getting processed, and then the AGI will complete in milliseconds and the call 
can continue. The secondary application can then do the URL POST. (You can 
probably whip this up in python very easily).

Not sure this solve the delay issue, however. If the secondary application 
stops running, you’d have to see if / how the AGI fails. I think it would just 
fail and the dialplan would just continue. Would need testing so it fails 
gracefully.

In my case this is for emergency services. The AGI calls a web URL with the

I had a situation that required this functionality -- processing a credit
card could take a second or two and we didn't want 'dead air' for our user
experience.

I created a pthread to play 'Please hold on while we process your card and
get ready for a good time...' while the main program continued with the
card authorization.

Most of the time the auth completed before the audio finished so it
appeared to be instantaneous to the caller.

The only caveat is to not interact (stdin/stdout) with Asterisk until
'stream file' in the thread completed.

it's the child (greater than 1).

I think php uses pcntl_fork().

I have an AGI that can sometimes take time complete. I don't want the
dialplan to be held up by the agi. Is there any way to call it and have
Asterisk continue with the dialplan?
