Guide to Diffusion, the Phabricator application for hosting and browsing
repositories.
Overview
========
Diffusion allows you to create repositories so that you can browse them from
the web and interact with them from other applications.
Diffusion can host repositories locally, or observe existing remote
repositories which are hosted elsewhere (for example, on GitHub, Bitbucket, or
other existing hosting). Both types of repositories can be browsed and
interacted with, but hosted repositories support some additional triggers
and access controls which are not available for observed repositories.
Diffusion is integrated with the other tools in the Phabricator suite. For
instance:
- when you commit Differential revisions to a tracked repository, they are
automatically updated and linked to the corresponding commits;
- you can add Herald rules to notify you about commits that match certain
rules;
- for hosted repositories, Herald can enforce granular access control rules;
- in all the tools, commit names are automatically linked.
The remainder of this document walks through creating, configuring, and
managing repositories.
Adding Repositories
===================
Repository administration is accomplished through Diffusion. You can use the
web interface in Diffusion to observe an external repository or create a new
hosted repository.
- For hosted repositories, make sure you go through the setup instructions
in @{article:Diffusion User Guide: Repository Hosting} first.
- For all repositories, you'll need to be running the daemons. If you have
not set them up yet, see @{article:Managing Daemons with phd}.
By default, you must be an administrator to create a new repository. You can
change this in the application settings.
Managing Repositories
=====================
Diffusion repositories have an array of configurable options and behaviors. For
details on the available options and guidance on managing and administrating
repositories, see @{article:Diffusion User Guilde: Managing Repositories}.
Repositories can also be managed via the API. For an overview on using the
API to create and edit repositories, see
@{article:Diffusion User Guide: Repositories API}.
Repository Clustering
=====================
Phabricator repository hosts can be set up in a cluster configuration so you
can lose hosts with minimal downtime and data loss. This is an advanced feature
which most installs do not need to pursue.
To get started with clustering, see @{article:Clustering Introduction}. For
details on repository clustering, see @{article:Cluster: Repositories}.
