The new elanspi driver in particular needs a lot of ioctl's during the
test. On a normal machine, this would run quite quickly (less than 5s),
however, in busy CI environments this can take longer than 30s, causing
timeouts currently.
Increase the timeout from 10s to 15s. For CI this means the timeout now
is 45s which is hopefully enough.
During startup, we'd always get:
(fprintd:151125): libfprint-uru4000-WARNING **: 12:16:56.724: ignoring unexpected interrupt 56aa
But we actually know what this interrupt is, and it's not unexpected, as
it tells us that the reader is now powered on.
The new features will be added in 0.16, so match against that. Also,
match against CI_PROJECT_NAME to detect our CI environment (and assume
that umockdev has been patched to the point of supporting all tests).
If the tile in question was hanging over the left edge we would not be
copying the full available width. Fix this and change the test to catch
the error condition (by forcing a too small image and overlap both
ways).
Simplify the code by only selecting the starting point inside the
image/frame and then just checking the both image and frame boundary in
the loop. Not quite as efficient, but it really shouldn't matter too
much here.
Long transfers need to be split into multiple chunks because of
limitations by the spidev kernel driver. If this happens, we need to
make sure that the CS line remains high between the different chunks.
Add code to split the transfer into chunks and ask the driver to not
deassert CS after the transfer. Technically, this is only an
optimization as concurrent access to another device might still cause
deselection. However, this should mean that devices work without having
to change the spidev module parameter.
Use the feature in the hope that it will work. However, print a message
(not a warning), to help with debugging in case someone does run into
issues because of this.
Previously, we checked hidraw devices against drivers by using the
HIDIOCGRAWINFO ioctl. While this works, it's not ideal for doing unit
tests since umockdev would have to implement hidraw ioctls.
The new approach uses the HID_ID property on the parent hid device,
which contains the VID/PID pair.
The driver has an internal cancellable that simply forwards the external
cancellation in the cancel callback. This is not really needed, we can
instead just use the external cancellable directly by fetching it using
fpi_device_get_cancellable().
The (trivial) CRC code was copied from gstreamer. However, the license
stated here was LGPLv2 rather than LGPLv2.1+. Identical code can currently
be found upstream in gstreamer licensed under LGPLv2+. As such, update
the license, making it more compatible with the rest of libfprint.
Also add the "or any later version" to upekts.c. The library was already
LGPL2.1+ at the time and libthinkfinger authors approved a license
change.
This command is useful to immediately continue rather than waiting for
input. It is only useful for non-scanning device actions and can be
important when steps need to be explicitly skipped (e.g. to inject an
error in the second command without a way to wait in between).
We were attaching the sources to the default main context. Instead, we
should be attaching them to the current tasks main context (or, failing
that, the current thread local main context).
