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.
This allows us to properly extract metadata for prints that are stored
on the device. We could for example delete the oldest prints first with
this information.
Heavily modified by Benjamin Berg <bberg@redhat.com> to port it to the
new libfprint API and adjust the coding style to follow more closely
other drivers.
When the device is deactivated while it is still active then the exit SM
needs to be executed from the SM that was active at the time. This is
signalled by is_active being set to FALSE while the active SM completes.
Call m_exit_start in those cases to ensure proper device deactivation.
This driver has a rather odd state machine and also used to mess iwth
the internal state of the image device. This code has been removed, but
is untested unfortunately due to a lack of hardware.
Most likely, this driver is not quite functional currently.
With this script it is possible to test libfprint/fprintd without any
hardware device. The image needs to be provides as a PNG with the alpha
channel storing the print data.
See the comment in the file on how the script can be used.
This is a rewrite of the core based on GObject and Gio. This commit
breaks the build in a lot of ways, but basic functionality will start
working again with the next commits.
Apply the previously added spatch/coccinell file to replace all
free/malloc/realloc calls with g_free/g_malloc/g_realloc. It also removes
all the error code paths that we do not need to check anymore.
This means that the returned data must be free'ed using g_free rather
than free, making memory management more consistent.
Add an spatch/coccinelle file to replace all free/malloc/realloc calls
with g_free/g_malloc/g_realloc. It also removes all the error code paths
that we do not need to check anymore.
These PNGs were generated using gimp simply by using the greyscale image
itself as an alpha mask. The reason to do this is solely for easier
consumption together with cairo A8 surfaces.
We will not want to install virtual drivers by default, yet they should
be inside the "all" category. So add a new "default" category and also a
separate array for the future virtual drivers.
We will use GUsb rather than libusb directly in the future. This should
simplify a lot of the integration work and changes such as supporting
hotplugging. It will also require quite a lot of internal changes.
