Getting Drupal 7 (almost) running on HHVM

In analogy to the article of the hiphop-php.com site, I’ll try to give you a tutorial on how to run Drupal on HHVM

HipHop for PHP

Installing HHVM

For the sake of this case-study, I used a Vagrant Ubuntu “Precise” 12.04 as my linux distribution. Also, to not screw up my local development machine, I’ll be using disposable virtual boxes.

Installing VirtualBox

https://www.virtualbox.org/wiki/Downloads Download and install the appropriate version of VirtualBox for your machine

Installing Vagrant

http://vagrantup.com/ Download and install the appropriate version of Vagrant for your machine

Downloading and Installing Precise64

cd ~/
git clone --recursive --branch 7.x-1.x http://git.drupal.org/project/vagrant.git
cd vagrant
vagrant box add base http://files.vagrantup.com/precise64.box
vagrant up
sudo nano /etc/hosts
# add 
# 33.33.33.10        drupal.vbox.local dev-site.vbox.local
vagrant ssh
# Update our packages
sudo apt-get update
sudo apt-get upgrade
exit
# After updates, run chef again
vagrant provision

Installing hiphop-php

cd ~/vagrant
vagrant ssh
sudo add-apt-repository "deb http://dl.hiphop-php.com/ubuntu precise main"
# no sources are present in hiphops repository, so remove them
sudo add-apt-repository --remove "deb-src http://dl.hiphop-php.com/ubuntu"
sudo apt-get update
sudo apt-get install hiphop-php -y --force-yes
exit

Create a config file

cd ~/vagrant
vagrant ssh
sudo mkdir /var/log/hhvm
sudo chmod 777 /var/log/hhvm/
sudo nano /etc/hhvm.hdf

Add the following snippet and save the file (/etc/hhvm.hdf)

Server {
  Port = 8000
  SourceRoot = /vagrant/public/drupal.vbox.local/www/
}

Eval {
  Jit = true
}
Log {
  Level = Error
  UseLogFile = true
  File = /var/log/hhvm/error.log
  Access {
    * {
      File = /var/log/hhvm/access.log
      Format = %h %l %u %t \"%r\" %>s %b
    }
  }
}

VirtualHost {
  * {
    Pattern = .*
    RewriteRules {
      dirindex {
        pattern = ^/(.*)/$
        to = $1/index.php
        qsa = true
      }
    }
  }
}

StaticFile {
  FilesMatch {
    * {
      pattern = .*\.(dll|exe)
      headers {
        * = Content-Disposition: attachment
      }
    }
  }
  Extensions {
    css = text/css
    gif = image/gif
    html = text/html
    jpe = image/jpeg
    jpeg = image/jpeg
    jpg = image/jpeg
    png = image/png
    tif = image/tiff
    tiff = image/tiff
    txt = text/plain
  }
}

Start the webserver

cd ~/vagrant
vagrant ssh
# Adding some debug modes
sudo hhvm --config /etc/hhvm.hdf --user vagrant --mode daemon -v "Log.Level=Verbose" -v "Log.NoSilencer=on" -v "Log.Header=on"
tail -f /var/log/hhvm/error.log

Go to http://drupal.vbox.local:8000/index.php in your browser
You can see a couple of errors in the terminal but none of them really are significant.

So I went looking for errors and found the following in /tmp/stacktrace-PID.log

So I suppose HHVM is not ready for PDO yet? I’d appreciate more input from people that are more knowledgable.

I think this is where my adventure with HHVM ends for now :-)
