Run your site on HHVM

[ptarjan]

I see X-Powered-By: PHP/5.3.10-1ubuntu3.9. :)

[h4cc]

You know, i would love to use hhvm to run the site and would switch instantly, if it would work.

There is a problem with HHVM and Doctrine ORM that needs to be fixed first :(

Thanks for your feedback!

[ptarjan]

Do you know the problem? I ran Doctine before but I only did the example site not anything too complicated.

[h4cc]

Did not have the time to debug the Problem. Will try if there is some time left and inform you then.

@h4cc run Doctrine 2.5-dev and it should work on HHVM (2.4.x is indeed not compatible with HHVM)

[h4cc]

@stof Thanks for that hint, tried it today and doctrine did not make any problems with hhvm.

But i had Problems with leaseweb/memcache-bundle because of the unkown memcached version "2.2.0b1".

But the fatal thing was, that hhvm fastcgi did die after a few request :( @ptarjan There has been no logging by hhvm on that. I tried HHVM 3.2.0 as well as 3.3.0-dev. Sounds a like this one here, but cant confirm https://github.com/facebook/hhvm/issues/2240

@h4cc that issue you linked seems to have been fixed in 3.2. Can you paste the exact errors you get? It should also make a stacktrace.log file in /tmp or the current directory, which would be useful.

[h4cc]

@ptarjan My logfiles under /var/log/hhvm/ are empty, but there is a stacktrace file:

I cant see anything bad.

[ptarjan]

There isn't enough info in there for me to debug. You can try installing the hhvm-dbg package which should have better asserts in it.

[h4cc]

Update: Even with HHVM v3.3 and FastCGI with Apache2 no success here.

So i used a fresh Ubuntu 14.04 VM and installed nginx with HHVM there using fideloper's howto (http://fideloper.com/hhvm-nginx-laravel). Till now its running fine, only once the HHVM daemon stopped because of multiple "Fatal"s in the error.log. Have a look, its really running with a fullstack symfony2 and doctrine with memcached :) http://78.46.85.248/

[ptarjan]

@h4cc is it still the same stacktraces? Is it consistent? Can you get 10 crashes and see if it is always in the same place.

[h4cc]

I have worked at a HHVM and partial Hack branch that will be ready in some time for production use :)
