No need to provide a script that will break usage of `meson test --gdb`
when we can use a native and cleaner alternative.
We can then ignore LIBFPRINT_TEST_WRAPPER in basic tests, while it is
still needed by umockdev tests.
We can avoid having multiple device feature-check functions now and
just rely on a few.
Add uncrustify config to properly handle begin/end deprecation macros.
It can be convenient for device users to check what it supports, without
having multiple functions to check each single feature.
So expose this and add tests.
We always assumed a device can verify, but nothing prevents from having
a device that only can identify or capture.
So, given that we've more fine grained checks, let's stop the task if
this is the case.
Allows drivers to define more fine grained features for devices, not
strictly depending on assumptions we can make depending on the
implemented vfuncs.
We keep this per class but could be in theory moved to each instance.
In any case, added an utility function to initialize it in the way we
can ensure that we've a consistent way for setting them across all the
devices.
We were crashing as trying to still call the identify vfunc, so check if
identification is supported and if not return a relative error.
Added test as well
We may want to be able to talk with the device while it's closed to
queue commands to be performed once it opens (could be even a script),
so to do this we need to close the device first, send those commands and
eventually process them.
We used a trick to send an invalid command before that was ignored by
release, but having the device available is just easier to handle.
So, when keep alive is enabled we don't stop the listener when closing
but only on actual device disposition.
The idea of the test was just checking what happens when we're opening a
device multiple times while a first request is still going.
However, it actually ends up also checking the previous commit change
because without it we'd stop the close iteration before the device is
actually closed and stop the open iteration before the device is
actually opened, leading to an infinite loop.
We're delaying any completed operation until we've completed an idle,
but the open/close state is changed and notified as soon as the device
completes the operation.
While this can be true, it means that we notify earlier than the finish
callback is actually called, while iterations are still needed to get
the actual state completed, and the current_task reset.
So if we'd open/close and iterate till fp_device_is_open() returns TRUE
we'd end up in a state in which the device is marked as ready, but it's
actually still busy since it's priv->current_task isn't unset yet.
The same if we'd try to do any action on notify::opened.
In case we do an early error return in verify and identify calls we
do not initialize the task data, but still in the finish functions we
still try to use it.
Avoid doing this, but just nullify the returned values.
When opening the device we can process commands that we left for that
after the previous close, to do that we only have to inject an invalid
command that will be processed (and ignored) while closing, so that at
next device opening we will be able to proceed with the previously
sent commands.
Add tests to finally check this case!
Each command should be separated by SLEEP to be considered as something
we want to perform during the current operation, otherwise will be used
by next operation consuming it.
In case we sent a sleep event to the device we may want to wait it to
emit the finger needed state before the timeout is completed.
So add a function to manage this for all the scan cases
This solves various problems:
1. It stays the same also if some drivers have been disabled
2. It uses a stable path for being imported by systemd
3. It is still checked for its validity by tests
4. It can be auto-generated using a simple command
When building in big endian architectures some device tests will fail,
as per this we're pretty sure that most of the drivers are not ready
to work in big-endian architectures.
Since we're aware of this, better to just stop supporting those drivers
instead of having each distribution to handle the problem.
So, add a list of supported drivers that is filled depending the
architecture type we're building on. Keep continue building those
drivers since we want to at least test-build them, but do not expose
them as libfprint drivers, so if a device in the system uses any of them
will be ignored.
At the same time, we keep track of the problem, so that we can fix the
drivers.

When serializing an image print in big endian machine we ended up
swapping the arrays contents two times, first when adding the values and
eventually when calling g_variant_byteswap which already handles this
properly.
With this, we get the test passing into s390x.
Fixes: #236
Identify function is supposed to propagate a boolean value, but we make
it return an integer instead on idle, this can be normally the same in
most of architectures, but not in BE ones.
So, make it return the proper type.
Fixes test failures in s390x.
