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.
Not having the diff is a bit painfull when the local version of
uncrustify differs from the one on the CI runner. So uncrustify in-place
and output the diff.
We build the HTML documentation. For feature branches, it is convenient
to be able to view the documentation easily. Expose them as artifacts
and add a link to the browser underneath the pipeline in the MR.
Unfortunately, it does not seem to be possible to link directly to the
HTML.
For some reason static checkers report that the auto-free is not run if
the goto exists the loop. It seems to me like that should work fine, but
we can simply make the analysers happy by moving it.
We need more than 1 line for assembling, but in general, we should
have a reasonable amount of lines. So use the width in the hope we'll
get an image that is about square at least.
Closes: #135
The minutiae detection might fail and we must not copy any data at that
point. So check g_task_had_error to ensure that we only do so when the
task was successful.
Fixes: #251
It appears the order of linking is relevant in this case, change it to
fix some linking issues.
It may be that there are better solutions to this problem.
Without this we get warnings like the following:
cc1: warning: .../_build/libfprint/nbis/libfprint-include: No such file or directory [-Wmissing-include-dirs]
We are already using a number of defines and autoptrs from newer GLib
releases. Add the appropriate compatibility defines rather than removing
the corresponding code.
Closes: #222
The callback function would continue processing even after having failed
the SSM already. This causes further invalid operations on the SSM.
This error was found using a coverity scan.
The g_object_new call had a NULL argument for a property. This meant
that the compiler could not warn about the lack of NULL termination for
the argument list.
Add the missing NULL termination.
We were not testing the image device error reporting functions yet
inside libfprint (fprintd already had such tests). Add tests to make
sure we catch errors earlier.
It is a good idea to report match results early, to e.g. log in a user
immediately even if more device interaction is needed. Add new _full
variants for the verify/identify functions, with a corresponding
callback. Also move driver result reporting into new
fpi_device_{identify,verify}_report functions and remove the reporting
from the fpi_device_{identify,verify}_complete calls.
Basic updates to code is done in places. Only the upekts driver is
actually modified from a behaviour point of view. The image driver code
should be restructured quite a bit to split the reporting and only
report completion after device deactivation. This should simplifiy the
code quite a bit again.
Some things were odd with regard to the ownership of passed objects. Try
to make things sane overall, in particular with the possible floating
FpPrint reference.
The progress report user data free func was not assigned and therefore
never called. Add the missing assign, potentially fixing memory leaks
(mostly relevant for bindings).
Just hiding tests that cannot be run does not seem like the best idea.
So add dummy tests that are skipped, to denote that we could test more
than we actually do (even if it is just for drivers that are not
enabled).
Unfortunately, the timeout handling cannot be simulated properly. This
also adds a workaround in the driver to not consider it a protocol error
if this happens.
Continuing an enroll was broken in case of a retry error. Explicitly add
code to wait for the finger to go OFF after a retry error, and ensure
that the enroll will continue once that has happened.
We cannot copy information from the class in the _init routine, instead,
this needs to be done in _constructed. Move the relevant code into a new
_constructed function to fix importing the bz3_threshold override from
drivers.
Fixes: #206
The offset stored for a frame was not always relative to the previous
frame. This was the case for reverse movement, but for forwrad movement
the offset was the one to the next frame.
Make the offset handling consistent and alwasy store the offset to the
previous frame. Also update the frame assembling code to add the offset
before blitting the frame (i.e. making it relative to the previous frame
there too).
Note that fpi_assemble_lines already made the assumption that this was
the case as it forced the offset for the first frame to be zero. As
such, the code was inconsistent.
This could affect the AES drivers slightly as they use hardware reported
values which might not adhere to these assumptions.
We prefixed them with fp- which is not as obvious as fpi-. Also,
explicitly mark them as private and to be skipped in the GObject
Introspection annotatinos.
Warning: FPrint: (Signal)fp-image-device-state-changed: argument object: Unresolved type: 'FpiImageDeviceState'
The private library needs to indirectly include fp-enum.h. This
dependency was not listed anyway, resulting in a race condition during
the build process.
The elan driver converts frames into a different format. These frames
are only needed to assemable the image and should be free'ed afterwards.
Fixes: #213
The manage-prints command would close the device twice when the user
hits an invalid number or 'n' and no prints need to be deleted.
Simply remove the erroneous call to fix the issue.
