Check if a device is too hot. If it is too hot already, refuse
operation. If it becomes too hot while an operation is ongoing, then
cancel the action and force a FP_DEVICE_ERROR_TOO_HOT return value.
Devices that are considered to never run hot will have FEATURE_ALWAYS_ON
set. If set, the UI can safely assume that it is fine to run fingerprint
authentication in the background without other user interaction.
Closes: #346
This will allow libfprint to cancel operations internally in the future.
If the internal cancellation method is used, then the private
current_cancellation_reason variable must be set to the GError. This
error will be returned when set.
This temperature model has three states:
* COLD
* WARM
* HOT
Device drivers can define the time it requires for the device to get HOT
and COLD. The underlying model assumes an exponential warming and
cooling process and enforces a cool-off time after the device has
reached the HOT state. This cool down period is however shorter than the
specified time in the driver.
The timeout is designed to continue commands automatically that are
common (e.g. opening the device). This doesn't really make sense for
scan commands, and removing the timeout enables test setups where user
interaction with the device may happen at arbitrary times.
One exception is device removal/unplug, in which case the timeout will
be added anyway.
Such an empty identify can be run by fprintd intentionally for duplicate
checking at the start of an enroll operation, which currently runs into
an error from the driver.
Avoid this by simply returning success immediately. This is fine, as
synaptics is only checking the explicitly passed list of prints rather
than using all available prints from the storage.
There are some large files, and in most setups (including CI runners) we
have multiple cores available. Use xargs to run multiple parallel
uncrustify jobs rather than one large one. Just hardcode 4 jobs and 4
files at the same time for now.
Pretty much all downstream distributions just enable all drivers anyway.
Also, it should work well enough, so it seems right to simply add
elanspi into the list of drivers that are enabled by default.
We were testing only for .ioctl files, but we may now have .pcap file
and ended up simply not running the synaptics test unless there was
still a .ioctl file present.
Simply remove the feature flag for the NO_LIST environment variable.
This also removes the IDENT variant for now as it has never been
implemented as described.
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).
