abbra told me where I was going wrong with the 'expected' target

For the kickstart test, it seems like it's a timing issue. We
added this 'install sssd-tools and enable debugging' step to try

with this, for now, because it's useful to have this debugging
anyway. If the problem starts happening again, we can fiddle

We're seeing a lot of tests fail on 404s when trying to access
the koji-rawhide repo (the repo for the Rawhide build tag, which
we use to get packages tagged since the last compose. nirik is
trying to figure this out from the server end, but for now at
least, let's mark the repo as skip_if_unavailable. This should
mean that if we hit a 404, the test will continue, it just won't
have access to the packages from that repo. Occasionally this
will cause a problem - a false failure or false pass - but this
still seems better than every test that hits it failing. The
false pass case is the most concerning, but I would hope in that
case some other tests from the same update would fail, making it
not an issue.

We have had several problems where rebasing from one release to

Sometimes it's difficult or impossible to do. All we want to do
here is check the rebase mechanism itself; we don't actually want
to assert that you can rebase to any specific other release.
For update tests, we should be able to use a non-standard ref
name for the ostree we build, embed into the installer image,
and install. That should mean we can then rebase to the standard
ref name for the same release, which should be much safer than
trying to rebase to a different release. We can't do this for
the compose tests, but at least for update tests I'm hoping this
makes things more robust.

This adds a new script - cleanup-needles.py - to use for cleaning
up old needles. It has to be used in conjunction with a database
query; the comment at the top explains how to do that query and
export the needed information. It produces a git commit with
needles that haven't matched since a certain date (specified in
the sql query) removed, subject to a 'keeplist' of needles we
keep even if they seem to be old.
I also enhanced check-needles.py to check for cases where tests
seem to be trying to match a tag we have no needles for. This
was necessary to find cases where the cleanup script was too
aggressive (i.e. the things that wound up in the 'keeplist'),
but it also turned out to find quite a lot of cases where the
code really *was* looking for a needle that had gone in a
previous cleanup or that never existed; the commits before this
one clean up a lot of those cases.
The code to decide which string literals are needle tags is
pretty dumb and hacky and needs some manual cueing sometimes -
that's what the `# testtag` changes in this commit are for.
Making it smarter would probably require this script to get a
lot more complicated and either incorporate or become a
tokenizer, which I don't really want to do.

There's no need to do all this 'check whether it's selected and

always click it. If it's already selected, clicking it again
doesn't hurt (one of these stanzas even clicks it *even if it's
selected*!)
If we need to cover both cases, we just need two needles with
the same tag, we don't need separate code paths. In each case,
though, we actually haven't matched one of the needles for ages
(the most recent was part_boot_selected, but now we're using
GPT by default, we won't hit that any more as it'll be the BIOS
boot partition that's selected by default), so delete the needles
we aren't matching any more. If we *do* hit any case where we

If we somehow *do* hit ext4 pre-selected again, this can still
be handled simply by adding an alternate

being selected; that avoids the need to keep an alternate code
path around.

This branch is very fragile, because the test won't fail if we
miss the match on the security needle. So in practice, we are
never going to notice when the needle goes stale, and we'll just
wind up never triggering this branch and always going down the
other path. That's the current situation: the security_install
needle last matched more than a year ago at least. Let's just
admit the truth here and drop the branch entirely.
Also update the cockpit_updates_restart_ignore needle. This is
in a similar case - we don't really notice when it goes stale,
as the test completes, it just takes a bit longer - but since
this one is quite easy to find, let's just update it instead of
dropping it.

The 'universal' flavor has been kinda pointless for some time
now. It dates back to the earliest days of openQA, before Pungi
4 was a thing, when composes were very different; we only built
a boot.iso and some live images nightly for Rawhide, these
weren't even formally grouped as a 'compose' at all (fedfind had
to invent the concept). The TCs/RCs had DVD installer images
(not *Server* DVD, at the time, just a universal DVD installer).
We wanted to run some tests on the DVD image if it was available,
but we still wanted to run them for the nightlies, so we invented
a whole mechanism for that - this 'universal' flavor, with some
complicated logic in fedora_openqa which schedules universal on
the 'best available' image it can find in the compose.
All this is functionally obsolete now. All composes we test are
now run through Pungi (except the live respins, but they aren't
relevant here). In current config, the Server DVD is non-failable
on x86_64 and aarch64, which means it will *always be there* -
if it fails to build, the compose itself fails, so we won't test
it. It's failable for ppc64le, but we don't care that much about
ppc64le; I'm fine with these tests just not running if the Server
DVD happens to fail in a ppc64le compose.
As a cherry on top, some of the 'universal' tests aren't really
universal anyway, they fail if you run them on a netinst (off
the top of my head, all the NFS install tests are like this, as
we use the ISO to populate the NFS share on the server end).
So let's just move all the tests that actually need an installer
image to the Server-dvd-iso flavor. Left over in the 'universal'
flavor are upgrade tests, which don't need an ISO at all - they
boot from hard disk images and run an upgrade using repos. We
can change the scheduler logic to be more simple for these, and
just always schedule them, with no ISO attached. We could even
rename this flavor 'upgrade', but it might not be worth it.
One slight complication is that the split happened to be helping
us avoid too many tests in a single support_server cluster; we
have a cluster of five support_server tests on Server-dvd-iso
and five support_server tests on universal. I try to avoid the
clusters getting too big as you need as many worker instances on
at least one worker host as your largest cluster; if you don't
have that many, the cluster's tests simply never get scheduled.
Requiring folks to have at least ten worker instances on one
host to run these tests is a bit of a big ask. So, to handle
that, we create a support_server_2 and have the former universal
tests use that one instead, so we'll have two separate clusters
on Server-dvd-iso now.

This keeps failing on the accessibility section, and looking at
the screenshots I realized why. When you press 'down', GNOME
doesn't just 'snap' to the new view, it does a smooth downward
scroll. We're often matching *while it's scrolling*, so the
needle match is right at the bottom of the screen. But then the
animation continues, so when we get to the click action (even
though we use click_lastmatch it's not *instant* in openQA),
the thing we're trying to click (the "Accessibility" section
title) is a bit further up the screen, and the click 'misses'.
So, we need to wait out the scroll then re-assert and click.
This unfortunately will make the test take about 30 seconds
longer, but I don't see another way to do it. We could maybe
shave the wait_still_screen to one second...

There's this awkward path for the live image install tests on
updates. We run the 'are the correct versions of all the packages
installed' check on these tests to ensure the right versions
actually made it onto the live image. So we don't run
`dnf -y update` at the end of repo_setup_updates on that path,
because if we did that, even if the packages on the live image
were old, we'd update them there and hide the problem.
However, this causes a bit of an ordering issue, because in
order to set up the advisory repo, we need to install a few
packages. What if the update under test includes one of those
packages, or a dependency that wasn't already installed? In
that case, we wind up with the older stable version of the
package (because obviously we can't install the newer version
from the advisory repo *before we've set up the advisory repo*),
don't update it later, and so the 'correct version' check at
the end of the test fails. See:
https://openqa.fedoraproject.org/tests/1778707 for a case of
this happening with a python-cryptography update.
Up till now I was trying to handle this by just updating the
specific packages we install, but that doesn't account for
*dependencies* of them. I looked down the path of trying to
generate a list of all those dependencies and update all of
them but it looks a bit mad. So instead let's try this. On that
specific path, we'll generate the "all installed packages" list
*before* we run repo_setup, so it just doesn't include anything
that gets installed during repo_setup. The implementation is a
bit icky but not too horrible.
We *could* just *always* generate the all installed packages
list earlier, but then that would mean we *wouldn't* catch dep
issues in this kind of package on the other test paths, whereas
currently we do. I don't want to lose that.

This makes the two rpm-ostree tests written for IoT - overlaying
and rebasing - work across all rpm-ostree-based flavors we
currently test (IoT, CoreOS and Silverblue) and runs them on
all those flavors.
This requires some other changes. For the Workstation ostree
installer update tests, we have install_default_update_ostree
upload a disk image and run these tests on that image. That means
install_default_update_ostree cannot use a scratch disk (as if
we boot it with two disks but only upload one, the subsequent
tests fail to boot, looking for the missing second disk), but its
specified disk size should be large enough for all updates.

What's supposed to happen here is the `do_bootloader` invocation
a few lines back boots to the installer, then here, we wait for
the install to complete and the system to reboot, and match the
bootloader again. However, on PXE installs, the bootloader screen
can hang around for quite a long time here, and if it does, we
can match it again before the installer starts up, and move on
too early. Hence the sleep.
It seems on current Rawhide 20 seconds isn't long enough - we're
still matching the installer bootloader after the sleep, see
e.g. https://openqa.stg.fedoraproject.org/tests/2431660#step/_boot_to_anaconda/3
This is causing the test to almost always fail (it'll only pass
if the install+reboot takes less than five minutes). Let's bump
it to 60 seconds and hope that's long enough.

This turns out to be overcomplicated. We don't need the special
handling for updates any more, because a few months after we
implemented it, we had to make sure the affected update tests had
an empty START_AFTER_TEST anyway, or else openQA would refuse to
schedule them. So we can just rely on the START_AFTER_TEST
condition for those now. We also don't need the additional
INSTALL_NO_USER condition; the only case where it's actually used
is for install_arm_image_deployment_upload on Workstation, and
that test does not have START_AFTER_TEST set, so the other
condition catches it for welcome screen handling purposes. There
is no need to nest the IMAGE_DEPLOY conditional inside a check
for the desktop and the INSTALL_NO_USER var either; we don't
test any other desktop on ARM, and the IMAGE_DEPLOY var is only
set for that one install_arm_image_deployment_upload test.

We currently snapshot after every run of _console_wait_login or
_graphical_wait_login, which means we snapshot *twice* on most
update tests as those modules get run twice. However, we almost
never use those snapshots. Snapshotting takes quite some time,
and hits the disk pretty hard, so we should avoid it unless it
is really needed.
We only have a few modules that are not fatal (and so might use
the snapshots), and most of those don't run after one of these
tests, or run after a later module that's also a milestone. Best
I can tell, only two test suites really need to use a snapshot
from a login test: server_cockpit_updates and modularity_tests.
To handle these and potential future cases, we'll add a new
module that does nothing, but is marked 'milestone', so it will
take a snapshot, and load that test after the login test if the
var LOGIN_SNAPSHOT is set, and set that var for those two suites.

We started using this in real composes a year or two back, so

The check_screen function checks for the existing tag

Abrt will not even start so we need to prolong

This is like the existing tests that build network install and
live images then install them, only for Silverblue. First we
build an ostree, using the standard configuration for the release
and subvariant but with the 'advisory' and 'workarounds' repos
included, so it will contain current stable packages plus the
packages from the update and any workarounds. Then we build an
ostree installer image with the ostree embedded, again including
advisory and workarounds repos in the installer build config so
packages from them will be included in the installer environment.
The image is uploaded, which completes the _ostree_build test.
Then an install_default_update_ostree test runs, which does a
standard install and boot from the installer image.
We do make a change that affects other tests, too. We now run
_advisory_post on live image install tests, as well as this new
ostree install image install test. It was skipped before because
of an exception that's really only needed for the netinst image
install test. In that test, packages from the update won't be
included in the installed system, so we can't run _advisory_post
on it. But for ostree and live image build/install tests, the
installed system *should* include packages from the update, so
we should check and make sure that it does.

I'm guessing this may be because currently aaa_setup clicks the

of intermediate state on snapshot restore. So, to try and avoid

Signed-off-by: Adam Williamson <awilliam@redhat.com>
This issue appeared when we started testing Rawhide updates, but
I only noticed it today. When testing Rawhide updates after
Branch point, the upgrade tests upgrade from Branched to Rawhide.
On Branched, updates-testing is enabled by default. We only
disable it when we reach `upgrade_run`, but by that point we've
already done a `dnf -y update` in `upgrade_preinstall` and
potentially installed other packages in steps between
`upgrade_preinstall` and `upgrade_run`. That can cause problems,
like today all FreeIPA upgrade tests on Rawhide are failing
because there's a newer freeipa in updates-testing for F37 than
is in the current Rawhide compose.
Solve this by disabling updates-testing before we do the update
in `upgrade_preinstall`. To avoid excessive code duplication,
factor out the repo disabling code.
We'll do this twice on upgrade tests now, but it shouldn't be a
problem.

This PR changes the way to download the test data into the VM.
Although it does not use a disk image as suggested in one
of the review, it does not clone the entire repository, but
a simple tar.gz file that holds the data which will be
distributed into the directory structure.
This way, the amount of data needed to be downloaded dropped
from approximately 50MB to below 2MB.
Also, the existing test suites were adapted to this situation.
Clocks' aaa_setup did not ever actually check the app launched
properly. It also doesn't handle granting permissions if
necessary, which the apps_startstop test for Clocks does do.
This makes the permission check in the apps_startstop test more

This is yet another twiddle to that same damn bit where we try

have already found and prepared updates before we got our

operation might work perfectly, but not update the package we
expect it to update, and the test may fail.
This time, let's try *always* refreshing, then wait a bit after
hitting the refresh button before we start looking for apply
or download to try and avoid the 'race' we were trying to solve
with the last tweak (where we hit refresh then immediately try
to hit a download or apply button which vanishes before we can
hit it). I think this should be safe as both KDE and GNOME
