Parameters
|
|
==========
|
|
|
|
Task-graph generation takes a collection of parameters as input, in the form of
|
|
a JSON or YAML file.
|
|
|
|
During decision-task processing, some of these parameters are supplied on the
|
|
command line or by environment variables. The decision task helpfully produces
|
|
a full parameters file as one of its output artifacts. The other ``mach
|
|
taskgraph`` commands can take this file as input. This can be very helpful
|
|
when working on a change to the task graph.
|
|
|
|
When experimenting with local runs of the task-graph generation, it is always
|
|
best to find a recent decision task's ``parameters.yml`` file, and modify that
|
|
file if necessary, rather than starting from scratch. This ensures you have a
|
|
complete set of parameters.
|
|
|
|
The properties of the parameters object are described here, divided roughly by
|
|
topic.
|
|
|
|
Push Information
|
|
----------------
|
|
|
|
``backstop``
|
|
Whether or not this push is a "backstop" push. That is a push where all
|
|
builds and tests should run to ensure regressions aren't accidentally
|
|
missed.
|
|
|
|
``base_repository``
|
|
The repository from which to do an initial clone, utilizing any available
|
|
caching.
|
|
|
|
``head_repository``
|
|
The repository containing the changeset to be built. This may differ from
|
|
``base_repository`` in cases where ``base_repository`` is likely to be cached
|
|
and only a few additional commits are needed from ``head_repository``.
|
|
|
|
``head_rev``
|
|
The revision to check out; this can be a short revision string
|
|
|
|
``head_ref``
|
|
For Mercurial repositories, this is the same as ``head_rev``. For
|
|
git repositories, which do not allow pulling explicit revisions, this gives
|
|
the symbolic ref containing ``head_rev`` that should be pulled from
|
|
``head_repository``.
|
|
|
|
``owner``
|
|
Email address indicating the person who made the push. Note that this
|
|
value may be forged and *must not* be relied on for authentication.
|
|
|
|
``message``
|
|
The try syntax in the commit message, if any.
|
|
|
|
``pushlog_id``
|
|
The ID from the ``hg.mozilla.org`` pushlog
|
|
|
|
``pushdate``
|
|
The timestamp of the push to the repository that triggered this decision
|
|
task. Expressed as an integer seconds since the UNIX epoch.
|
|
|
|
``hg_branch``
|
|
The mercurial branch where the revision lives in.
|
|
|
|
``build_date``
|
|
The timestamp of the build date. Defaults to ``pushdate`` and falls back to present time of
|
|
taskgraph invocation. Expressed as an integer seconds since the UNIX epoch.
|
|
|
|
``moz_build_date``
|
|
A formatted timestamp of ``build_date``. Expressed as a string with the following
|
|
format: %Y%m%d%H%M%S
|
|
|
|
``tasks_for``
|
|
The ``tasks_for`` value used to generate the decision task.
|
|
|
|
Tree Information
|
|
----------------
|
|
|
|
``project``
|
|
Another name for what may otherwise be called tree or branch or
|
|
repository. This is the unqualified name, such as ``mozilla-central`` or
|
|
``cedar``.
|
|
|
|
``level``
|
|
The `SCM level
|
|
<https://www.mozilla.org/en-US/about/governance/policies/commit/access-policy/>`_
|
|
associated with this tree. This dictates the names of resources used in the
|
|
generated tasks, and those tasks will fail if it is incorrect.
|
|
|
|
Try Configuration
|
|
-----------------
|
|
|
|
``try_mode``
|
|
The mode in which a try push is operating. This can be one of:
|
|
|
|
* ``"try_task_config"`` - Used to configure the taskgraph.
|
|
* ``"try_option_syntax"`` - Used when pushing to try with legacy try syntax.
|
|
* ``"try_auto"`` - Used to make try pushes behave more like a push on ``autoland``.
|
|
* ``"try_select"`` - Used by ``mach try`` to build a list of tasks locally.
|
|
* ``None`` - Not a try push or ``mach try release``.
|
|
|
|
``try_options``
|
|
The arguments given as try syntax (as a dictionary), or ``None`` if
|
|
``try_mode`` is not ``try_option_syntax``.
|
|
|
|
``try_task_config``
|
|
The contents of the ``try_task_config.json`` file, or ``{}`` if
|
|
``try_mode`` is not ``try_task_config``.
|
|
|
|
Test Configuration
|
|
------------------
|
|
|
|
``test_manifest_loader``
|
|
The test manifest loader to use as defined in ``taskgraph.util.chunking.manifest_loaders``.
|
|
|
|
Target Set
|
|
----------
|
|
|
|
The "target set" is the set of task labels which must be included in a task
|
|
graph. The task graph generation process will include any tasks required by
|
|
those in the target set, recursively. In a decision task, this set can be
|
|
specified programmatically using one of a variety of methods (e.g., parsing try
|
|
syntax or reading a project-specific configuration file).
|
|
|
|
``filters``
|
|
List of filter functions (from ``taskcluster/taskgraph/filter_tasks.py``) to
|
|
apply. This is usually defined internally, as filters are typically
|
|
global.
|
|
|
|
``target_tasks_method``
|
|
The method to use to determine the target task set. This is the suffix of
|
|
one of the functions in ``taskcluster/taskgraph/target_tasks.py``.
|
|
|
|
``release_history``
|
|
History of recent releases by platform and locale, used when generating
|
|
partial updates for nightly releases.
|
|
Suitable contents can be generated with ``mach release-history``,
|
|
which will print to the console by default.
|
|
|
|
Optimization
|
|
------------
|
|
|
|
``optimize_strategies``
|
|
A python path of the form ``<module>:<object>`` containing a dictionary of
|
|
optimization strategies to use, overwriting the defaults.
|
|
|
|
``optimize_target_tasks``
|
|
If true, then target tasks are eligible for optimization.
|
|
|
|
``do_not_optimize``
|
|
Specify tasks to not optimize out of the graph. This is a list of labels.
|
|
Any tasks in the graph matching one of the labels will not be optimized out
|
|
of the graph.
|
|
|
|
``existing_tasks``
|
|
Specify tasks to optimize out of the graph. This is a dictionary of label to taskId.
|
|
Any tasks in the graph matching one of the labels will use the previously-run
|
|
taskId rather than submitting a new task.
|
|
|
|
Release Promotion
|
|
-----------------
|
|
|
|
``build_number``
|
|
Specify the release promotion build number.
|
|
|
|
``version``
|
|
Specify the version for release tasks.
|
|
|
|
``app_version``
|
|
Specify the application version for release tasks. For releases, this is often a less specific version number than ``version``.
|
|
|
|
``next_version``
|
|
Specify the next version for version bump tasks.
|
|
|
|
``release_type``
|
|
The type of release being promoted. One of "nightly", "beta", "esr78", "release-rc", or "release".
|
|
|
|
``release_eta``
|
|
The time and date when a release is scheduled to live. This value is passed to Balrog.
|
|
|
|
``release_enable_partner_repack``
|
|
Boolean which controls repacking vanilla Firefox builds for partners.
|
|
|
|
``release_enable_partner_attribution``
|
|
Boolean which controls adding attribution to vanilla Firefox builds for partners.
|
|
|
|
``release_enable_emefree``
|
|
Boolean which controls repacking vanilla Firefox builds into EME-free builds.
|
|
|
|
``release_partners``
|
|
List of partners to repack or attribute if a subset of the whole config. A null value defaults to all.
|
|
|
|
``release_partner_config``
|
|
Configuration for partner repacks & attribution, as well as EME-free repacks.
|
|
|
|
``release_partner_build_number``
|
|
The build number for partner repacks. We sometimes have multiple partner build numbers per release build number; this parameter lets us bump them independently. Defaults to 1.
|
|
|
|
``release_product``
|
|
The product that is being released.
|
|
|
|
``required_signoffs``
