This is primarily useful for SPI devices. These devices sometimes needs
a combination of an SPI and HID device, so discovery is a bit more
complicated.
Upstream systemd/udev is pulling our autosuspend hwdb, so if udev is new
enough, then there is no need to install the file. As such, add
auto-detection logic for the scenario.
This also changes the name of the option and the type to "feature".
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.

We want systemd to pull our hwdb. In order to ease this, always build
the hwdb file, even if it is disabled.
Once systemd has merged the rules, downstream should turn off the rules
in libfprint. The default in libfprint will also be changed to not build
the hwdb (udev_rules option) eventually.
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
The public API uses gio and gobject header, ensure that these are in the
list of Required pkg-config modules, otherwise they are added to
Required.private which is not OK.
To avoid conflicts with previous libfprint version and make sure that the
target version is the correct one (plus to allow parallel install in some
distros), let's use a versioned naming for the library keeping the abi
version in sync.
Fixes#223
We're using some new features, and we may use more in future so better to
bump the version to the minimum required than look back given we're still
unstable.
Fixes#204
We were passing around the common cflags and setting them for each library
or executable, but this is just a repetition given we can just use
add_project_arguments for this.
Just define once and modify its syntax when needed.
Use a more verbose definition for the min/max version (instead of just
join the split version) so that in case we may depend on a specifc glib
micro release during development.
Meson files are normally using 4-spaces to indent and functions use first
parameter on the same line while others at next indentation level, not
following the parenthesis indentation.
So adapt libfprint to follow the meson standard.
These examples have not been ported. In addition, they are also not very
useful these days, as the demo application offers a much nicer view to
view images from a sensor.
The tests cannot work without the introspection bindings. So put them
into a corresponding if branch and also add the correct dependency on
libfprint_typelib for them to be run.
This changes the cancellation logic a bit to ensure we always deactivate
the device (equivalent to the AWAIT_OFF state in the driver). All
commands except for the deactivation command should be cancelled when an
operation is stopped, this is to ensure that the LED is turned off at
the end of an operation.
