This adds an entirely new workflow for testing distribution
updates. The ADVISORY variable is introduced: when set,
main.pm will load an early post-install test that sets up
a repository containing the packages from the specified update,
runs dnf -y update, and reboots. A new templates file is
added, templates-updates, which adds two new flavors called
updates-server and updates-workstation, each containing
job templates for appropriate post-install tests. Scheduler is
expected to post `ADVISORY=(update ID) HDD_1=(base image)
FLAVOR=updates-(server|workstation)`, where (base image) is one
of the stable release base disk images produced by createhdds
and usually used for upgrade testing. This will result in the
appropriate job templates being loaded.
We rejig postinstall test loading and static network config a
bit so that this works for both the 'compose' and 'updates' test
flows: we have to ensure we bring up networking for the tap
tests before we try and install the updates, but still allow
later adjustment of the configuration. We take advantage of the
openQA feature that was added a few months back to run the same
module multiple times, so the _advisory_update module can
reboot after installing the updates and the modules that take
care of bootloader, encryption and login get run again. This
looks slightly wacky in the web UI, though - it doesn't show the
later runs of each module.
We also use the recently added feature to specify +HDD_1 in
the test suites which use a disk image uploaded by an earlier
post-install test, so the test suite value will take priority
over the value POSTed by the scheduler for those tests, and we
will use the uploaded disk image (and not the clean base image
POSTed by the scheduler) for those tests.
My intent here is to enhance the scheduler, adding a consumer
which listens out for critpath updates, and runs this test flow
for each one, then reports the results to ResultsDB where Bodhi
could query and display them. We could also add a list of other
packages to have one or both sets of update tests run on it, I
guess.
