GtkStyleContext will be deprecated in gtk 4.10.
https://docs.gtk.org/gtk4/class.StyleContext.html
This preserves code blocks where additional GtkStyleContext operations
were used, such as gtk_style_context_save/restore.
Otherwise when users close and reopen the window they will face a
“Failed to claim fingerprint device Synoptics Sensors: the device is
already claimed by another process” error message.
Fixes#1983
For sake of simplicity we were just releasing a state once we got a
callback, however during the handling of the callback itself we are
still technically under that scenario, so we should release a state only
after the callback is completed.
This is more relevant now since when converting errors to human readable
strings we check the state we are in, and so we need to ensure that this
state is preserved until this point.
In case the device got disconnected while enrolling we should not try
to stop or unclaim it, but indeed show an error related to the device
not being available.
To get this we only have to remove the enrolling and claimed states now
Use flags to track the dialog actions state so that we can:
1. Remove multiple flags to track specific states
2. Prevent starting again an action we're still waiting for completion
3. Handle global visual elements (such as the busy spinner) correctly
Specifically point 3. allows to ensure that when doing concurrent
actions such as prints listing and device claiming, we will stop the
spinner only once all the operations are over.
We were a bit too permissive in handling the AlreadyInUse error during
claim, as we assumed it was always us causing it instead of properly
handing the case a device was already claimed by another caller.
So to ensure this is the case we need to avoid multiple calls to claim
until we've finished one.
Unfortunately we can't rely on a cancellable here as we may end up
cancelling the request that succeeded and we'll only get an
AlreadyClaimed error without know if it was us succeeding.
Fixes: #1201
We unset the local device early when releasing it, so use the one we
get the callback instead of relying in the private instance that has
been already cleared.
A duplicatend and translated string could be passed to gettext another
time. If that string can be translated, then a static string would be
returned rather than the const one, causing an invalid free.
Fixes: #1149
When a retry event happens we need to wiggle the label, unfortunately we
can't just use translate operations via CSS so we need to simulate it using
padding.
Also we have to manually reset the retry class once the animation is done
otherwise gtk won't re-animate again once the class is added (in the same
paint cycle).
Implement the new designed interface for fingerprint enrollment, so that the
dialog is now based on a stack of views:
- A list of devices to choose (shown only if multiple are available)
- A gallery of enrolled prints available where manage them
- An enrollment progress view when enrolling a new finger
Move part of the logic into a new FingerprintManager (to manage gdbus proxies
generated via gdbus-codegen) that is created when configuring the current
user and that tracks the devices states, while move most of the UI into a new
CcFingerprintDialog that does all the operations in async way.
Due to fprintd lack of APIs, there are few features missing, compared to
the final design (none is a regression):
- Identify the finger when the enroll dialog is visible
- Delete a single fingerprint
- Highlight the finger when the sensor is touched during enrollment
- Add customized labels to fingerprints
- Devices hotpluging
However most of the code has been written considering these, and so they could
be easily implemented in future re-iterations once newer APIs are defined for
such bits.
