Does Unit support Symfony's kernel.terminate?

[p4block]

Migrated my app from nginx+php-fpm to Unit. We're using Sentry for profiling and error handling.
There's this bit:

If your web server is using FastCGI, our SDK utilizes the kernel.terminate event

, which means the response is sent to the user before the performance data is sent to Sentry.

If your web server isn't using FastCGI, you can run Relay locally on the same machine or a local network that can act as a proxy/agent.

Doing this will make the PHP process send requests to your local Relay, which will then forward them to Sentry, instead of sending requests to Sentry directly.

FWIW.

I tried the first test program from here and it did indeed create the file.

$ curl localhost:8080/fastcgi_finish_request.php
<p>Calling to <code>fastcgi_finish_request()</code>.</p>
<p>If success, the file /home/andrew/src/php/text.txt will be created.</p>
$ cat /home/andrew/src/php/text.txt

That suggests that fastcgi_finish_request() worked which is seemingly what is used by kernel.terminate.

So it looks like it at least has a chance of working. I guess your best bet is to just try it...

Feel free to report back your findings. If it doesn't work we can look at what needs fixing in Unit.

Well, I'm a big dummy. The actual "problematic" php call it runs is indeed fastcgi_finish_request

Which is specifically mentioned in the basic php docs as supported!

Next week I am tasked with intense performance testing and I will check if it works as advertised, but there's no reason it shouldn't.
