PHP-FPM vs spawn-fcgi
July 04, 2009 10:33AM
Hi,

With Andrei not working on the project anymore I'm considering moving back
to using spawn-fcgi. The new patches are barely tested (it compiles so it's
fine doesn't cut it) and I assume no one is actually working on the code.

Is there a disadvantage for me if I were to head back to using spawn-fcgi
(Speed, stablility)?

you need process manager (supervisord/god/runit/daemontools) if you
want to use spawn-fcgi (except for supervisord which can manage and
spawn fastcgi processes)

You can also use php-cgi -b $port with a combination of sudo and such
and the right environment variables.

That's what I was doing using ubuntu's upstart. Any supervisor should
be able to do the same. I don't see any benefits from using spawn-fcgi
since you still have to manage all the pools independently.

What would give you more confidence in the project? Obviously the
first step is compiling but we do have a lot of people using those
patches (we should figure out some sort of metrics system so we know)
- I am using 5.2.10 myself without any issues (except my caching issue
which is only on a couple machines and probably due to something else
it's been around even with andrei's last patch I believe)

I'm open for ideas on how to ensure things are "working" - even andrei
himself could release a buggy version and would have to release a
fixed patch for it. Only so much we can do.

I'm open for ideas - perhaps a survey to try to determine how many
people are using php-fpm, what version, what platforms, etc. I could
actually whip up a script to report peoples php configuration so we
get ideas of it all and make it easy to auto submit a phpinfo() or
something.

I think we need a continuous build procedure so when the latest version is
built, unit tests are ran and the results reported back. We also need
someone who can understand the code, because if a serious flaw shows up (it
can happen). Who's going to fix it? It'd be the end of PHP-FPM. Also, I
think we should push really hard to get this into PHP, but I'm not sure how
to do this. Suggestions?

Yes, please setup a survey, it's the first step to getting some reports
going. With this we could spot bugs much easier, ex : Does this extension
affect PHP-FPM, etc ... Something is better than nothing right?

I've already got 4-5 PHP/PECL developers on the hook. Right now I'm
waiting to hear back from them on their recommendations for next
steps. So getting it into PHP or at least into PECL is already being
worked on.

Continuous builds would be great, I'm just trying to determine how
test cases can be written.

And yes, someone who understands the internals would be great. That's
the great part of open source though, everyone can contribute, read,
fix, etc.

Correct.
