There are two variants one with storage and identify support and the
other without storage.
It implements the following commands:
* INSERT id
* REMOVE id
* SCAN id
* ERROR error-code
* LIST (returns saved print)
The INSERT/REMOVE/LIST commands are only available in the storage
driver. The SCAN command emulates presenting a finger.
These commands can be send ahead of time, and will be queued and
processed when appropriate. i.e. for INSERT/REMOVE that is immediately
when possible, for SCAN/ERROR processing is delayed.
The LIST command is always processed immediately.
Note that only a single command can be send per socket connection and
the command must be send in a single message. The socket will be closed
after the command has been processed.

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.
Related to #236
Add a new test that checks that the unsupported list is not out of date.
As the wiki can be edited at any time, add this as a further optional
check into the CI pipeline.
We only use the rules/hwdb to enable auto-suspend. So, instead of
shipping our own rules, we can just use the existing autosuspend rules
and ship a hwdb that sets the appropriate flag.
Closes: #336
there is no specific API for report finger status,
finger needed status is set when captrue sample cmd send, once cmd receive correct,
finger is pressing on sensor.
The gallery needs to be copied, as such we must do a deep comparison
instead of comparing the pointers. We also can't do the comparison
afterwards, as the gallery is owned by the operation and that operation
is finished already.
This tests all relevant scenarios of device removal, i.e.:
* device is not open
* device is currently closing
* device is open and idle
* device is currently opening
* device is open and active
The test ensures that in all scenarios the following holds true:
* device "removed" signal is only emitted after the action completes
* context "device-removed" signal is only emitted after the device has
been closed
Note that the "opening" case is special. Here we confirm that a success
from "open" will not be overriden by a FP_DEVICE_ERROR_REMOVED error, in
order to correctly signal that the internal device state is open and it
needs to be closed.
We require the close call, but as the underlying transport layer is
gone, it will generally just return an error.
In principle, it makes sense to think of close as a function that always
succeeds (i.e. it makes no sense to try again). Should the device be in
a bad state, then a subsequent open() will simply fail.
While the image device has its own finger status tracking, we use a simpler
version as public data information, so let's just report the finger-on/off
and when a finger is expected to the parent class.
Verify that this happens as expected using the virtual-image class
It is not very useful to just delete the data again after a failure, as
it might be useful for debugging. Just store it into an "errors"
subdirectory of the PWD in the hope that this is a sane location.
Note that it'll error out if the directory already exists, but that
should be acceptable in all cases. i.e. it won't exist in the CI and
developers can just wipe the directory.
During verify/identify complete we replace the error pointer that the driver
returned with another error we created, after clearing that one.
However, when we initialize a new error the compiler may reuse the same
allocation of the cleared one, and this might lead to a test failure.
So, don't be so fragile and ignore the pointer check
The unittest_parser script would try to import FPrint gi module, but it
would fail as per the fact that none is installed yet, so make sure that
we don't load any FPrint module until we try to actually run the tests
Devices with no storage don't allow listing prints, and if we try to do
that, we'd end up in trying to call a NULL function pointer, causing a crash
So always check if the device has storage before calling the list vfunc, and
if we fail, return an error.
Include an unit-test to verify this situation
