We don't have docs for how to upgrade Mercurial in CI. A lot of it is organic institutional knowledge that lives in various people's heads. That's not good for continuity of business. This commit starts to establish documentation for how to upgrade Mercurial in Firefox CI. The documentation for updating things in-tree is pretty robust (because I've done it a handful of times and know what is involved). But the docs for OpenCloudConfig and Puppet could certainly be improved. I'll poke the respective maintainers of these systems to help improve these docs as a follow-up.

TaskCluster Task-Graph Generation
|
|
=================================
|
|
|
|
The ``taskcluster`` directory contains support for defining the graph of tasks
|
|
that must be executed to build and test the Gecko tree. This is more complex
|
|
than you might suppose! This implementation supports:
|
|
|
|
* A huge array of tasks
|
|
* Different behavior for different repositories
|
|
* "Try" pushes, with special means to select a subset of the graph for execution
|
|
* Optimization -- skipping tasks that have already been performed
|
|
* Extremely flexible generation of a variety of tasks using an approach of
|
|
incrementally transforming job descriptions into task definitions.
|
|
|
|
This section of the documentation describes the process in some detail,
|
|
referring to the source where necessary. If you are reading this with a
|
|
particular goal in mind and would rather avoid becoming a task-graph expert,
|
|
check out the :doc:`how-to section <how-tos>`.
