Job Transforms
==============
.. note::
These transforms are currently duplicated by standalone Taskgraph
and will likely be refactored / removed at a later date.
A job description says what to run in the task. It is a combination of a
``run`` section and all of the fields from a task description. The run section
has a ``using`` property that defines how this task should be run; for example,
``mozharness`` to run a mozharness script, or ``mach`` to run a mach command.
The remainder of the run section is specific to the run-using implementation.
The effect of a job description is to say "run this thing on this worker". The
job description must contain enough information about the worker to identify
the workerType and the implementation (docker-worker, generic-worker, etc.).
Alternatively, job descriptions can specify the ``platforms`` field in
conjunction with the ``by-platform`` key to specify multiple workerTypes and
implementations. Any other task-description information is passed along
verbatim, although it is augmented by the run-using implementation.
The run-using implementations are all located in
``taskcluster/gecko_taskgraph/transforms/job``, along with the schemas for their
implementations. Those well-commented source files are the canonical
documentation for what constitutes a job description, and should be considered
part of the documentation.
following ``run-using`` are available
* ``hazard``
* ``mach``
* ``mozharness``
* ``mozharness-test``
* ``run-task``
* ``spidermonkey`` or ``spidermonkey-package``
* ``debian-package``
* ``ubuntu-package``
* ``toolchain-script``
* ``always-optimized``
* ``fetch-url``
* ``python-test``
