.. task:: UpdateSuiteLintianCollection

UpdateSuiteLintianCollection task
---------------------------------

This task implements the :task:`UpdateDerivedCollection` interface, updating
a derived :collection:`debian:suite-lintian` collection from a base
:collection:`debian:suite` collection.

All active items in both collections are considered relevant.

Given a base :artifact:`debian:binary-package` artifact with an architecture
other than ``all``, a derived item with the name
``{srcpkg_name}_{srcpkg_version}_{architecture}`` is desired.

Given a base :artifact:`debian:source-package` artifact or for a base
:artifact:`debian:binary-package` artifact with ``Architecture: all``,
derived items with the names
``{srcpkg_name}_{srcpkg_version}_{architecture}`` are desired for the
following values of ``architecture``:

* ``source`` (only for a source package artifact with no corresponding
  binary package artifacts)
* ``all``
* each architecture where another base :artifact:`debian:binary-package`
  artifact exists for the same source package name and version

The child work requests are for :task:`Lintian` tasks, with the following
``task_data`` in addition to anything specified in this task's
``child_task_data``:

* ``input``:

  * ``source_artifact`` (:ref:`lookup-single`): the relevant
    :artifact:`debian:source-package` artifact in the base collection
  * ``binary_artifacts`` (:ref:`lookup-multiple`): a list of the relevant
    :artifact:`debian:binary-package` artifacts in the base collection

Each child work request has an event reaction as follows, where
``{derived_collection}`` is the ``derived_collection`` from this task's
data:
