Pantheon Loves Open Source

Here Are Some of Our Open Source Contributions:

Drupal

Pantheon team members helped lay out the core architecture for the new Configuration Management system, financially sponsored the initial development, and provided space for sprinting and evangelism for this crucial feature set.

WP-CLI

An update to the scaffold child-theme command to correctly enqueue the themes in the generated functions.php. Pantheon has also financially sponsored the work to make a more restful WP-CLI.

Drush

Pantheon supports the ongoing work to maintain and improve Drupal's command-line interface.

Drupal SDK and Starter Kits

This is Pantheon's recommended starting point for creating new decoupled Drupal 9 backend sites. It builds on Pantheon's default Drupal 9 upstream to provide best practices, default configuration, and accellerator tools for using drupal 9 as a backend in decoupled archictures. Unlike with earlier Pantheon upstreams, files such as Drupal Core that you are unlikely to adjust while building sites are not in the main branch of the repository. Instead, they are referenced as dependencies that are installed by Composer.

Decoupled WordPress Composer

This is Pantheon's recommended starting point for creating new decoupled Wordpress backend sites. It builds on Pantheon's default Wordpress composer upstream to provide best practices, default configuration, and accellerator tools for using Wordpress as a backend in decoupled archictures. Unlike with earlier Pantheon upstreams, files such as Wordpress Core that you are unlikely to adjust while building sites are not in the main branch of the repository. Instead, they are referenced as dependencies that are installed by Composer.

Fedora

Pantheon team members are part of Fedora's Proven Testers program. Additionally, Pantheon runs one of the largest production Fedora server deployments on the internet, taking advantage of the cutting-edge technologies and the positive benefits of a fast release cycle.

Sensu

Pantheon team members are core contributors to Sensu, a next-generation monitoring system that enables Pantheon to move quickly and ensure properly functioning systems.

cURL

Contributions to main cURL examples for novel use of cURL for stream parsing

systemd

Pantheon works closely with the team working on systemd, a linux sys V init replacement that provides process and container management facilities, including hosting sprints with national and international attendence. Pantheon team members have worked on contributed tools for systemd and journald as well.

Fusedav

The Valhalla file system and open-source fusedav client are pushing status quo, delivering unprecendented funcationality for content-management storage backends.

Panopoly

A powerful base distribution for building Drupal distributions with powerful end user features.

Twisted Python

Pantheon has actively sponsored the Twisted Python project, which we use for DNS, SSH, and HTTP services.

jenkins-cert-auth

Check out this plugin for Jenkins to enable certificate-based authentication and authorization.

kibana_utils:

We open-sourced a set of utilites for working with the Kibana log visualization front-end, available on github.

Terminus

A modern PHP based tool for interacting with Pantheon sites.

Let's Encrypt

Pantheon is a sponsor, which supports design work on the ACME protocol, the Boulder certificate authority software, and the Let's Encrypt infrastructure that provides widely accepted, no-cost certificates for HTTPS (and other TLS deployments).

LibCloud

Enhancements for the python-based cross-cloud provisioning tool.

Chef

Pantheon uses Chef extensively. Our approach to Chef is community focused. We leverage community cookbooks as a first option and contribute improvements upstream if we need additional functionality. Being the first large scale systemd user also means we are constantly contributing systemd support to community cookbooks, for example, the logstash and elasticsearch cookbooks. Also check out some Chef report handlers.

Site Audit

A collection of Drush commands that analyze a site for compliance with Drupal best practices. Used on Pantheon to power Launch Check, and open-sourced on Drupal.org.

Generate Errors

A Drupal module development utility for intentionally triggering a variety of errors, open-sourced on Drupal.org.

Go

Small (but none-the-less important) fixes to Go core HTTP libraries.

WP Redis

A WordPress plugin to help you back your WP Object cache with Redis, a high-performance in-memory cache.

Pantheon-sessions

A WordPress plugin that allows the use of native PHP sessions while staying horizontally scalable.

stunnel

An update to stunnel to support systemd-based socket activation released in stunnel version 5.05.

Improved Documentation

Across many projects large and small! We <3 doc improvements and one-line commits! Did we mention our Documentation site is Open Source?

WordPress Launch Check

A set of automated checks that website developers can run to make sure their WordPress site is ready to launch. While developed by Pantheon and integrated into the Pantheon dashboard, WordPress Launch Check is intended to be fully usable outside of Pantheon as an open source WP-CLI plugin on GitHub.
