Image devices are simply deactivated suddenly. As such, the cancellation
logic of FpDevice is not really useful there, but the documentation was
apparently accidentally copied unmodified.
This is unlikely to happen in a real world scenario and currently breaks
running the CI test (not the umockdev based ones) while building the
flatpak. Lower the severity to avoid aborting because there is a
warning.
Image devices may return a FP_DEVICE_ERROR_NOT_SUPPORTED error once capture
is already started, in such case handle the error going in non imaging mode
This is based on the patch and observation from Bastien that some
URU4000B devices do not use encryption by default (it is a configuration
stored within the firmware). As such, it makes sense to always detect
whether encryption is in use by inspecting the image.
The encryption option would disable flipping of the image for the
URU400B device. Retain this behaviour for backward compatibility.
The code would just read 4096 bytes from the packet, without checking
the size and neither setting short_is_error. It is not clear whether
packets from the device are always 4096 bytes or not. But the code
assume we always get a full line, so enforce that and use the actual
packet size otherwise.
This was not used. The old driver used this if creating a USB transfer
failed, however, we delay any such failures (which cannot really happen)
into the callback today, where the error is handled differently.
The GPtrArray needs to be created at some point. Also, reference
counting was wrong as submitting the transfer sinks the ref, but we rely
on it surviving.
Note that we really should change this to only have one in-flight
transfer and starting a new one after it finishes.

When sending static data, it would not be copied. The function that
sends it assumed that it should be free'ed though.
Fix this by simply always making a copy.
The driver would warn about the fact that a state change is queued, but
still queue it a second time. This would result in deactivation to run
twice.
See: #216
The image driver may still be deactivating when a new activation request
comes in. This is because of a hack to do early reporting, which is
technically not needed anymore.
Fix the immediate issue by properly reporting the retry case. The proper
fix is to only finish the previous operation after the device has been
deactivated.
One can set it in the project, but that doesn't get copied to forks. And
that means the coverage information isn't printed in MRs sometimes.
Just add it into .gitlab-ci.yml so that it always works.
The driver might forget to set the type of the print. Catch that error a
bit earlier rather than failing when the API user tries to load it from
disk again.
The type of the print (RAW or NBIS) needs to be filled in by the driver.
For most drivers the image devices does this (NBIS), but the
corresponding call was missing in the upekts driver, rendering the
enrolled print unusable.
__handle_incoming_msg would copy the payload of the message into a newly
created buffer just to destroy it again immediately after calling the
callback. Just reference the correct address inside the original package
instead.
Also, in one case the extra buffer was leaked afterwards.
The driver would correctly calculate the amount of extra space needed to
receive the whole packet. It would also request the correct number of
bytes for this transfer.
However, the reallocated buffer to hold this data was directly derived
from the expected payload size and did not include the overhead.
Make the code more explicit and get rid of the confusing
MAX_DATA_IN_READ_BUF define that hides details on buffer allocation
calculation from the code.
The device is already beeing de-initialised from the verify/enroll
commands. Trying it again will result in a timeout error as it is not
responding properly at that point.
