This sets us up to test the release-blocking aarch64 disk images
(Minimal, Server and Workstation). It also allows for testing
armhfp disk images on aarch64 worker hosts (though my testing of
that isn't going too well so far), and fixes the initial-setup
handling for a change upstream ('use password' is now the default
so we don't need to choose it). We rewire disk image deployment
test loading to work through the generic loader code rather than
using ENTRYPOINT, as it allows us to more gracefully handle
graphical (Workstation) vs. console (Server, Minimal), moving
the code for handling console initial-setup to a helper function
just like the code for gnome-initial-setup and having _console_
wait_login call it when appropriate. We also tweak desktop_vt a
bit because now we need to switch from a console running as test
to a desktop, which breaks the assumption that the highest
numbered session of user test is the desktop...

"""This is an openQA template loader/converter for FIF, the Fedora Intermediate Format. It reads
|
|
from one or more files expected to contain FIF JSON-formatted template data; read on for details
|
|
on this format as it compares to the upstream format. It produces data in the upstream format; it
|
|
can write this data to a JSON file and/or call the upstream loader on it directly, depending on
|
|
the command-line arguments specified.
|
|
|
|
The input data must contain definitions of Machines, Products, TestSuites, and Profiles. The input
|
|
data *may* contain JobTemplates, but does not have to and is expected to contain none or only a few
|
|
oddballs.
|
|
|
|
The format for Machines, Products and TestSuites is based on the upstream format but with various
|
|
quality-of-life improvements. Upstream, each of these is a list-of-dicts, each dict containing a
|
|
'name' key. This loader expects each to be a dict-of-dicts, with the names as keys (this is both
|
|
easier to read and easier to access). In the upstream format, each Machine, Product and TestSuite
|
|
dict can contain an entry with the key 'settings' which defines variables. The value (for some
|
|
reason...) is a list of dicts, each dict of the format {"key": keyname, "value": value}. This
|
|
loader expects a more obvious and simple format where the value of the 'settings' key is simply a
|
|
dict of keys and values.
|
|
|
|
The expected format of the Profiles dict is a dict-of-dicts. For each entry, the key is a unique
|
|
name, and the value is a dict with keys 'machine' and 'product', each value being a valid name from
|
|
the Machines or Products dict respectively. The name of each profile can be anything as long as
|
|
it's unique.
|
|
|
|
For TestSuites, this loader then expects an additional 'profiles' key in each dict, whose value is
|
|
a dict indicating the Profiles from which we should generate one or more job templates for that
|
|
test suite. For each entry in the dict, the key is a profile name from the Profiles dict, and the
|
|
value is the priority to give the generated job template.
|
|
|
|
This loader will generate JobTemplates from the combination of TestSuites and Profiles. It means
|
|
that, for instance, if you want to add a new test suite and run it on the same set of images and
|
|
arches as several other tests are already run, you do not need to do a large amount of copying and
|
|
pasting to create a bunch of JobTemplates that look a lot like other existing JobTemplates but with
|
|
a different test_suite value; you can just specify an appropriate profiles dict, which is much
|
|
shorter and easier and less error-prone. Thus specifying JobTemplates directly is not usually
|
|
needed and is expected to be used only for some oddball case which the generation system does not
|
|
handle.
|
|
|
|
The loader will automatically set the group_name for each job template based on Fedora-specific
|
|
logic which we previously followed manually when creating job templates (e.g. it is set to 'Fedora
|
|
PowerPC' for compose tests run on the PowerPC arch); thus this loader is not really generic but
|
|
specific to Fedora conventions. This could possibly be changed (e.g. by allowing the logic for
|
|
deciding group names to be configurable) if anyone else wants to use it.
|
|
|
|
Multiple input files will be combined. Mostly this involves simply updating dicts, but there is
|
|
special handling for TestSuites to allow multiple input files to each include entries for 'the
|
|
same' test suite, but with different profile dicts. So for instance one input file may contain a
|
|
complete TestSuite definition, with the value of its `profiles` key as `{'foo': 10}`. Another input
|
|
file may contain a TestSuite entry with the same key (name) as the complete definition in the other
|
|
file, and the value as a dict with only a `profiles` key (with the value `{'bar': 20}`). This
|
|
loader will combine those into a single complete TestSuite entry with the `profiles` value
|
|
`{'foo': 10, 'bar': 20}`.
