During verify/identify complete we replace the error pointer that the driver
returned with another error we created, after clearing that one.
However, when we initialize a new error the compiler may reuse the same
allocation of the cleared one, and this might lead to a test failure.
So, don't be so fragile and ignore the pointer check
The unittest_parser script would try to import FPrint gi module, but it
would fail as per the fact that none is installed yet, so make sure that
we don't load any FPrint module until we try to actually run the tests
Devices with no storage don't allow listing prints, and if we try to do
that, we'd end up in trying to call a NULL function pointer, causing a crash
So always check if the device has storage before calling the list vfunc, and
if we fail, return an error.
Include an unit-test to verify this situation
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 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.
This was added as alias to the error check, but given we're passing to the
callback both the error and the match itself, we can just avoid adding an
extra parameter that could be confusing (as may imply that the matching
happened).
Also clarify the documentation and ensure that the match value is properly
set in tests.
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.
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.
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.
