Installing symlinks pointing to directories with install_subdir() is
broken (see https://github.com/mesonbuild/meson/pull/14471). Let's work
around the issue for now by manually installing the standalone directory
until the issue is fixed upstream and available in meson in all supported
distributions.
meson follows symlinks by default, so make sure we use
follow_symlinks=False if meson is new enough and rsync otherwise like
we already do for other testdata subdirectories.
Currently, to run the integration tests, it's still necessary to
install various other build tools besides meson: A compiler, gperf,
libcap, ... which we want to avoid in CI systems where we receive
prebuilt systemd packages and only want to test them. Examples are
Debian's autopkgtest CI and Fedora CI. Let's make it possible for
these systems to run the integration tests without having to install
any other build dependency besides meson by extracting the logic
required to run the integration tests with meson into a separate
subdirectory and adding a standalone top-level meson.build file which
can be used to configure a meson tree with as its only purpose running
the integration tests.
Practically, we do the following:
- all the integration test directories and integration-test-wrapper.py
are moved from test/ to test/integration-test/.
- All the installation logic is kept out of test/integration-test/ or
any of its subdirectories and moved into test/meson.build instead.
- We add test/integration-test/standalone/meson.build to run the
integration tests standalone. This meson file includes
test/integration-test via a cute symlink hack to trick meson into
including a parent directory with subdir().
- Documentation is included on how to use the new standalone mode.
- TEST-64-UDEV-STORAGE and TEST-85-NETWORK are changed to generate separate
units for each testcase to make them behave more like the other integration
tests.
Now our baseline of meson is 0.62, hence install_symlink() can be used.
Note, install_symlink() implies install_emptydir() for specified
install_dir. Hence, this also drops several unnecessary
install_emptydir() calls.
Note, the function currently does not support 'relative' and 'force' flags,
so several 'ln -frsT' inline calls cannot be replaced.
Then, we can drop ugly workaround in meson.build.
The .link file is not necessarily synced with 99-default.link.
Also, 99-default.link is not updated so frequently.
Let's manually sync it when necessary.
Let's get rid of the configure script for this use case by just
implementing the necessary logic in integration-test-wrapper.py.
We need to get rid of our usage of configure scripts to allow enabling
the History= setting.
When '--resolve-names=late', systemd-udevd resolves user/group names
during each event being processed, and does not verify names on parse.
When '--resolve-names=never', systemd-udevd refuses any user/group names
on parse. Hence, the parser of udev rules behaves diffrently. Let's not
convert 'never' -> 'late' silently, and use the specified option as is.
This also updates man page and shell completion for --resolve-names
option.
TEST-74-AUX-UTILS covers many subtests, as it's a catch-all job, and a few
need a VM to run. The job is thus marked VM-only. But that means in settings
where we can't run VM tests (no KVM available), the entire thing is skipped,
losing tons of coverage that doesn't need skipping.
Move the VM-only subtests to TEST-87-AUX-UTILS-VM that is configured to only
run in VMs under both runners. This way we keep the existing tests as-is, and
we can add new VM-only tests without worrying. This is how the rest of the
tests are organized.
Follow-up for f4faac2073
Currently, mkosi GitHub action complains the following:
===
Could not find 'setfiles' which is required to relabel files.
===
Let's tentatively disable SELinux test.
This tests the whole shebang:
1. That ukify can generate them properly
2. That systemd-boot can dissect them properly
3. That systemd-stub can accept profile selection propery
4. That the profile information ends up in /run/systemd/stub/ properly
5. That systemd-measure correctly calculates the expected PCR 11 values
for each profile and that we can unlock a public-key bound LUKS
volume with it
Rebuilding the integration test every time is very slow. Let's
introduce a way to iterate on an integration test without rebuilding
the image every time. By making a btrfs snapshot before we run the
integration test, we can then systemctl soft-reboot after running
the test to restore the rootfs to a pristine state before running
the test again.
As /run/nextroot will get nuked on reboot or soft-reboot, we introduce
a tmpfiles snippet to make sure it is recreated every (soft-)reboot
and adapt the existing tests to deal with this new symlink.
This adds a testsuite unit to run systemd-networkd-tests.py. This is
mkosi only for now as python is not available in the images set up
by the bash framework. We give the test a lower priority as it takes
a while to run so we want to start it as soon as possible.
Having these named differently than the test itself mostly creates
unecessary confusion and makes writing logic against the tests harder
so let's rename the testsuite-xx units and scripts to just use the
test name itself.
Let's make this behave more like all the rest of the meson stuff.
This also is the first step to making it a bit more flexible so we
can define integration tests in different ways as will be seen in
the next commits.
Some integration tests take much more time than others, let's add
a test param that can be used to configure this and integrate it
with the slow-tests meson option.
Direct kernel boot results in much faster boot times so let's use
it by default.
We disable it for tests that need to reboot because +-50% of the
time, doing a reboot when using direct kernel boot causes qemu to
hang on reboot. Until we figure that out, let's use UEFI for the
tests that need to reboot.
If we set it to '0' if integration tests are not enabled then we can't
enable them from the command line since environment from meson takes
priority over environment variables from the command line.
We also rename the related variables to avoid conflicts with the
existing integration_tests variable.
Let's use the new follow_symlinks flag instead on newer meson to.
We also switch back to copying symlinks instead of following them
and add an exclude for 25-default.link which becomes dangling when
installed and recreate it manually instead.
