Drupal on Heroku

The repository is a sandbox for trying to run Drupal on Heroku. There are still some issues that need to be resolved:

• ISSUE: Drupal requires that its public filesystem is within the Drupal root. Heroku's app filesystem is read-only, so this is not possible. This is primarily a problem because you cannot enable CSS and JS aggregation. That's pretty much a requirement for running Drupal in production since IE only supports 32 stylesheets. This is easily exceeded once you add a handful of modules. (Confirmed by Heroku support on 2013-11-11)

Setup Notes

PHP Configuration

php.ini - Loaded php configuration. Loads the mbstring exension for better unicode support.

heroku/mbstring.so - Precompiled mbstring extension. (yandod/heroku-libraries)

Sites Configuration

sites/site.php - Points Drupal to the sites/heroku/ folder when running on *.herokuapp.com.

Utility Class

heroku/heroku.inc - Utility class for running in the Heroku environment. Currently a function for parsing the database config from the DATABASE_URL environment variable and running an array in Drupal's preferred format.

array Heroku_Util::parseDatabaseUrl($url == false)

Settings.php

sites/heroku/settings.php - An automatic Drupal configuration sample for running in a Heroku environment.

// Include the utilty class and setup the database
require_once(DRUPAL_ROOT . '/heroku/heroku.inc');
$databases['default']['default'] = Heroku_Util::parseDatabaseUrl();

AmazonS3 File Storage

Include the AmazonS3 Drupal module so we can store files.
