"""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}`.
