When constructing a minimal environment for osbuild the exported
dirs lacked "schemas" so the test_exports.py test failed on RHEL8.
This commit adds it (and also "assemblers" for good measure). With
that the test will pass.
Older version of `lsblk --json` will not have the plural `mountpoints`
but only a singular `mountpoint`. But newer version lost the
singular `mountpoint` in the json. Adjust the test accordingly.
The new `create_image_with_partitions()` helper fails under rhel8
currently. The reason is that `mkfs.ext4 -E offset=` will warn
in older versions about a partition table and require user input.
This got fixed `e2fsprogs` 1.46.3 in Jul 2021 but RHEL8 still
has 1.45.

The stable stream currently doesn't have a new enough bootupd to pass
the tests for the bootupd stage. Let's update to `:testing` for now
and we'll switch back to `:stable` later.
Add the bootupd stage to install GRUB on both BIOS and UEFI systems,
ensuring that your bootloader stays up-to-date.

Extract a new helper `make_fake_tree()` that generalizes the existing
helper `make_fake_input_tree()`. The later will always create the
content under `{basedir}/tree` which is convinient for input tree
based tests but too specialized when using it in different contexts.
The existing `make_fake_input_tree()` is preserved unchanged and
becomes just a tiny wrapper.
This commit allows to exclude preserving ownership from an object
export. This is required to fix the issue that on macOS the an
podman based workflow cannot export objects with preserving
ownerships.
Originally this was a `no_preserve: Optional[List[str]] = None)`
to be super flexible in what we pass to `cp` but then I felt like
YAGNI - if we need more we can trivially change this (internal)
API again :)
Similar to the aleph file created for builds of FCOS based on ostree
commit inputs, this adds an aleph file that contains information about
the initial deployment of data when the disk image was built
A new stage is preferred here as both the org.osbuild.ostree.deploy
and org.osbuild.ostree.deploy.container stages need an aleph file and
use of the aleph file may depend on the project/product. For example,
right now CoreOS is the only project that uses an aleph file, but others
may want it in the future.
Diffs for stage tests have changed after the sources were updated.
Update them to match expected behaviour. This was mostly done with
some form of:
```
foo=update-crypto-policies;
sudo tools/gen-stage-test-diff --libdir . --store /var/osbuild/store/ test/data/stages/$foo > test/data/stages/$foo/diff.json
```
For the dracut one I had to figure out what new kernel was used
and the new modules and update the vanilla.json file to get the
test to pass.
For the rpm one I had to also update the metadata.json with something
like:
```
sudo python3 -m osbuild --libdir . --store /var/osbuild/store/ --export tree \
--output-directory /var/osbuild/out/ test/data/stages/rpm/b.json --json \
| jq .metadata >test/data/stages/rpm/metadata.json
```
This adds a new key masked_generators, similar to masked_services,
which masks systemd generators from running at boot, by creating
symlinks to /dev/null in /etc/systemd/systemd-generators, as
described in:
https://www.freedesktop.org/software/systemd/man/latest/systemd.generator.html#Description
This will be useful for the automotive project, as it allows disabling
of unsupported things like sysv or rc.local legacy support, while
improving boot performance.
This helper can be used to implement a strategy to find the oldest
cache entries and evict them when the cache is full.
The implementation uses the `atime` of the per object `cache.lock`
file and ensures in `load()` that it's actually updated.
This commit adds mount output to the error raised by
FileSystemMountService.mount(). This is useful when running into
mount failures during osbuild runs.
The issue was discovered while debugging a mount failure for
osbuild-composer PR#3820. Initially osbuild PR#1490 was meant
to fix it but it turned out there is a third mount helper in
the code that was originally overlooked (sorry for that!).
While debugging a failure of osbuild-composer [0] on fc39 it was
noticed that a mount failure does not include the output of
the mount command:
```
File "/usr/lib/python3.12/site-packages/osbuild/mounts.py", line 78, in mount
path = client.call("mount", args)
^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.12/site-packages/osbuild/host.py", line 348, in call
ret, _ = self.call_with_fds(method, args)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.12/site-packages/osbuild/host.py", line 384, in call_with_fds
raise error
osbuild.host.RemoteError: CalledProcessError: Command '['mount', '-t', 'xfs', '-o', 'ro,norecovery', '--source', '/dev/rootvg/applv', '--target', '/tmp/tmpjtfmth56/app']' returned non-zero exit status 32.

subprocess.run(

raise CalledProcessError(retcode, process.args,
```
which makes diagnostic errors harder of course. This commit adds
a test that ensures that mount output is visbile and also changes
the code to include it.

This commit extends the current support for OpenSCAP
tailoring by accepting an array of key/value overrides.
Users will be able to specify override values for specific
rules that will update the value when remediating the
image.
The next commit will add a stage test that requires erofs-utils. Let's add it
into the buildroot in a separate commit, so the history is more readable.
Add a simple stage test for the erofs stage. It uses dump.erofs
instead of mounting the file because the kernel in the GH runners
do not support mounting erofs just yet.
For our Fedora CoreOS disk images we set the partition labels (name)
for the partitions. This is also supported using the primitives here
in OSBuild, but it wasn't obvious that I needed to set the name in
the mpp-define-images definition. Let's set the name there, but let's
also allow osbuild-mpp to set the `id`, which is what is used later
to access that partition from the `name` too if `id` isn't set.
This means we allow something like:
- name: BIOS-BOOT
type: 21686148-6449-6E6F-744E-656564454649
bootable: true
uuid: FAC7F1FB-3E8D-4137-A512-961DE09A5549
size: 100
rather than requiring something like:
- id: BIOS-BOOT
name: BIOS-BOOT
type: 21686148-6449-6E6F-744E-656564454649
bootable: true
uuid: FAC7F1FB-3E8D-4137-A512-961DE09A5549
size: 100
When loop.Loop() is called and a new loop device must be allocated
there is no gurantee that the correct device node is available on
the system. In containers /dev is often just a tmpfs with static
device nodes. So when /dev/loopN is not available when the
container is created the device node will be missing even if
`get_unbound()` create a new loop device for us.
This commit ensures that the device node is available. It creates
it unconditionally and ignores any EEXIST errors to ensure there
is no TOCTOU issue.
Note that the test could have passed a `Loop(dir_fd=open(tmpdir))`
instead of creating/patching loop.DEV_PATH but it seems slightly
nicer to test the flow without a custom dir_path as this is what
the real code that creates a loop device is also using.
Quick rename to have our wording be in-line with the new differences
between stage unit tests and stage integration tests; also being applied
to the guides.
When osbuild.loop.Loop calls `__init__()` it assigns the `self.fd`
on open. However if that open call fails for whatever reason
(not found, permissions) the cleanup in `__del__` will fail in
confusing ways because `self.fd` is not initialized yet. It
also prevents the correct error from getting reported. A tiny
test is added to ensure this does not regress.
This commit removes some unnecessary custom tmpdir() fixtures
and uses the pytest buildin tmp_path instead.
Some custom tmpdir fixtures are left in place as they configure
the tmp location to be under `/var/tmp` which is not trivial to
do with pytests `tmp_path`. Not sure or not if the is a deep
reason there for using /var/tmp. I assume it's to ensure that
the tests run on a real FS not on a potential tmpfs but I don't
have the full background so didn't want to change anything.
