The state directory will generally be the same as the hardcoded one.
However, being able to override it is important for testing purposes, so
add the option.
For sensors with internal storage we may want to garbage collect prints.
Adding this API means we can list all local prints, allowing us to find
out whether there are prints on the device's storage with no
corresponding print on the host.
--localstatedir (and --prefix) will now be ignored in favour of this
hardcoded path. This is in preparation for a change to use systemd's
StateDirectory feature.
- Add a finger selected signal, so that when an "automatic" finger
is selected for verification, we know which one to scan
- Fix the finger print numbers list to use GPOINTER_TO_INT /
GINT_TO_POINTER
- Make sure the gallery is NULL when there's no prints available
- Don't use identification when a finger number is provided
- Add support for selecting the finger number in verify
- Add support for fatal warnings there as well
- Remove SetUsername itself, and add a username parameter to DeviceClaim,
ListEnrolledFingers and DeleteEnrolledFingers.
- For each of those calls, check that the incoming connection is allowed
to operate on that particular username
- Don't require a claimed device to list or remove fingerprints
- Clean up username and sender when releasing the device
- Modify the storage backend to not require an opened device to list
or delete fingerprints
- Add a simple test program to list registered fingerprints for the
usernames passed as argument
