An application terminating because of a signal like SIGSEGV, SIGABRT and
friends, will exit with a signal number that is 128 + $SIGNAL_NUMBER, so
let's ensure that the daemon has not been terminated because of a such error
This makes even more sense with address sanitizer builds, as the daemon
would exit with abort.
Make possible to run tests with address sanitizer to quickly check for
memory errors, although we have to disable the error exit code in case of
leaks because we have some which are due to something else down in the stack
(and LSAN suppression files doesn't allow to define the stack to ignore
as we can in valgrind).
However, we'd abort in case of memory errors anyways, so this still helps
to prevent major problems, while still logging the leaks.
In order to run pam module tests with ASAN we need to manually pass the
library to LD_PRELOAD, as we do for the wrapper.
In order to run pam module tests we need to pass the libraries via
LD_PRELOAD, this supports a list of library paths, so use the compiler in
order to find their full paths (with soname) and check their presence.
In order to support linker scripts we need to introduce a workaround.
See meson issue https://github.com/mesonbuild/meson/issues/6880
Meson supports checking for default arguments natively without having to
do this for each one, so just use this feature.
Not doing this will become a warning as per meson 0.52.0 [1].

The test doesn't need any assertion because we're calling DeleteEnrolledFingers
and in case it fails a net.reactivated.Fprint.Error.PermissionDenied error
would be thrown, and thus an exception would be raised at python level, making
the test to fail.
As per systemd's documentation:
If multiple directories are set, then in the environment variable the
paths are concatenated with colon (":").
Handle that case by splitting the paths if there's a ":" in the
variable.
Closes: #50
test_claim_from_other_client_is_released_when_vanished would fail on
the CI but work on a local system because we wouldn't want long enough
for the "vanished" code path to be taken into account. Add a small
timeout to make sure it works on the CI as well.
enroll_image() was always waiting for enroll-completed rather than for
what the caller expected as the result.

We run a certain number of tests right now, without being able to easily
run them separated or to check which one failed.
So add a script to inspect all the available unittests per each python
script and use it to figure out the tests we can run in meson.
As per this, define a global 'python_tests' variable in meson that allows
to register new python tests easily without having to repeat the settings
for all the tests.
For each test we have, we check if we can fetch a list of unit tests, and
if possible we create a meson test for each one.
Otherwise we just fallback to normal behavior.
This is something that can be hopefully implemented into upstream meson [1].

The unit tests files are provided as python files, adding a tool that
allows to list them in order to be able to run them easily via
python3 -m unittest module.Class.test_method
The test file calls self.daemon_start() in order to start fprintd and
locate the virtual image device that's needed for the test to run.
However, since the virtual image driver is not available on all
libfprint installations, the test should be skipped if the driver is not
available.
The skipping mechanism used to work, by checking if self.device is None.
This is based on the assumption that self.device would be set to None in
cases where the driver is not available. However, even in the past
self.device is only set to None in the tearDown method and not in setUp,
so presumably in edge cases it didn't entirely work.
However, since 0fb4f3b021 which
consistently removes the self.device attribute rather than setting it to
None, the "self.device is None" check no longer works. In particular,
the following error message is shown:
test_manager_get_default_device (__main__.FPrintdManagerTests) ...
Did not find virtual device! Probably libfprint was build without
the corresponding driver!
ERROR
After this patch, the following is shown:
test_manager_get_default_device (__main__.FPrintdManagerTests) ...
Did not find virtual device! Probably libfprint was build without
the corresponding driver!
skipped 'Need virtual_image device to run the test'
We fix this bug by consistently setting self.device to None, in both the
setUp method before daemon_start gets called, and in tearDown. We also
make the same change to self.manager for consistency.
The issue was not caught on CI, as the CI configuration always installs
a libfprint version that has the virtual_image device explicitly enabled
in the preparation phase.
Avoid using a temporary file for reading the utilities output, so we can
read it as it comes, ignoring the previous one, and avoiding open/closing
the file.
To keep the output printing on cleanup working, adding an utility function
that reads the output and save it for later printing
Avoid repeating the same operation to launch the utilities all the times,
but provide instead a function that allows to start a process and saves its
output without having to handle this in every test.
Simplify the operation when we just want the final output, still reusing
the same code.
When starting an enroll when verification is in progress (and vice-versa) we
emit an AlreadyInUse error, however when calling VerifyStop() during an
enrollment (and vice-versa) we just return a NoActionInProgress error, which
is not the case.
So let's be consistent and change the error type.
When we run tests in a system with real devices, we may try to initialize
the real ones, while we can just ignore them all in tests.
We do it in setUp instead of setUpClass to allow tests to change this if
they need to, but just for temporary.
