When using fpi_usb_transfer_submit_sync we still need to unref the transfer
once done with it, so let's use an auto pointer so we free it also on
errors and early returns without having to handle this manually.
When a transfer is completed, we automatically unref it since we can't
consider it valid anymore since this point.
Update the drivers not to free the transfer after submitting anymore.
When a machine is completed, we automatically free it since we can't
consider it valid anymore since this point.
Update the drivers not to free the SSM on completion callback anymore.
As per commit 201b5a961 we use g_date_copy() to copy the date, however the
GLib implementation is done assuming that the GDate getters are always used
as the copy function doesn't preserve the original format of the date
(whether is using julian days or dmy), and the synaptics driver access to
the dmy values directly, without using the getter that would recompute the
proper values.
Causing a read error of unset values.
So, to avoid this, just use the g_date_get_* getters to retrieve the day
month and year for for defining the print enroll id.
Use the same approach of GTask, making possible to set the data from a
function. Givent the fact that a SSM has now a device parameter, it's
generally not needed to pass an extra data value.
In such case make it possible to set it and to define a destroy-notify
function to handle its destruction when freeing the SSM.
As the driver is not a normal image device, we need to add a custom
script to test it. Note that the ioctl dump must also be manually
modified unfortunately as the state is tracked incorrectly for the
device by umockdev-record.
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.
