(Drupal) Packagist

This is a hacked up fork of packagist for use with Drupal. The forking and hacking was done for want of a fast way to experiment with the problem domain while developing the Drupal-specific functionality separately.

All things considered, it would be best to provide separate repositories for the following:

• The Packagist/WebBundle by itself
• HA functionality -- mostly the queueing used to bootstrap by traversing all the drupal.org project repos with worker nodes
• Drupal-specific applications for the above
• Drupal CLI tools for parsing update and release info as a thing unto itself

Instead, we have added the queuing and Drupal-specific functionality in place. The main workflow so far has been to install the application as normal and then populate the database so that you can generate a composer repository like so:

./app/console packagist:bulk_add --repo-pattern \
'http://git.drupal.org/project/%2$s' --vendor drupal $(curl \
https://www.drupal.org/files/releases.tsv | grep 7.x | awk '{ print $3 }' | sort | uniq -)

Running 10 AWS c3.large instances to consume the queue filled by the packagist:bulk_add command allows the process to complete in a few hours.

Experimental support for automatic updates has been added in the form of a foreground package upsert command that gets invoked by the packagist:drupal_org_update command, which parses the drupal 7 new releases rss feed. You would need to invoke this command with cron or similar to keep the application up to date with drupal.org and you would need to monitor disk space since the package information is read by cloning a bare repo from drupal.org and never removing it. You could consider updating the drupal/parse_composer project to add an appropriate cleanup method to the Repository class there, or just sweep out the cache directory composer uses at the end of the cron job.

Unfortunately, the rss feed references the projects by drupal module name, which is always snake_case, but the repo URL is case sensitive and therefore stupid project names with uppercase letters will cause things to break. The only obvious workaround would be to periodically run through the releases.tsv. In limited sampling, only useless modules had this problem.

Requirements

• MySQL for the main data store
• Redis for some functionality (favorites, download statistics)
• Solr for search
• git/svn/hg depending on which repositories you want to support

Installation

1. Clone the repository
2. Copy app/config/parameters.yml.dist to app/config/parameters.yml and edit the relevant values for your setup.
3. Install dependencies: php composer.phar install
4. Run app/console doctrine:schema:create to setup the DB.
5. Run app/console assets:install web to deploy the assets on the web dir.
6. Make a VirtualHost with DocumentRoot pointing to web/

You should now be able to access the site, create a user, etc.

Setting up search

The search index uses Solr 3.6, so you will have to install that on your server. If you are running it on a non-standard host or port, you will have to adjust the configuration. See the NelmioSolariumBundle for more details.

You will also have to configure Solr. Use the schema.xml provided in the doc/ directory for that.

To index packages, just run app/console packagist:index. It is recommended to set up a cron job for this command, and have it run every few minutes.

Day-to-Day Operation

There are a few commands you should run periodically (ideally set up a cron job running every minute or so):

app/console packagist:update --no-debug --env=prod
app/console packagist:dump --no-debug --env=prod
app/console packagist:index --no-debug --env=prod

The latter is optional and only required if you are running a solr server.
