workspace: Ensure that _createBestLayout() always returns a layout
When opening a large number of windows, the computed space and scale for
a layout can become negative due to the per-row/per-column spacing. This
is smaller than the initial values of lastSpace and lastSpace, leading
to a null return which then causes all sorts of other issues resulting
in the workspace becoming invisible.
This change ensures that the function always returns a layout, even if
it may look a bit broken and does not conform to the scale/space
requirements which are impossible to fulfill for the given number of
windows. It's better than displaying nothing, since it allows users to
move/close windows and restore this to a more usable state.
gdm: Override any other lower-priority service message on error
When we got an error, all the other HINT or INFO messages are not useful
anymore and delaying to show them is just a waste of time and may be
even wrong in scenarios with fast authentication devices.
An example are the fingerprint devices, where the user may touch the
sensor repeatedly while we may still show the "touch the sensor" hint
instead of notifying of possible errors.
So, in case we got an error override all the other errors coming from
the same service with lower priority.
gdm: Filter service non-error messages on verification stopped or failed
Once the verification has been stopped or has failed all the messages
that are not of error type are just not needed or wrong to show.
For example, in the fingerprint case we may still show the hint to swipe
or touch the device, while the fingerprint PAM service has already been
stopped.
So filter them by adding a new function that adds a null message to the
queue, overriding all the messages that have a lower priority.
gdm: Add ability to queue a message overriding ones with less priority
There are cases in which a service may want to override a message with
one coming with higher priority, for example an info or hint message
isn't useful anymore if we've already got an error message.
In the same way when a service has been stopped we don't care anymore
showing its info or hint messages, while it still may be relevant to show
errors.
An example is the fingerprint service that may emit errors quickly while
the hints messages should not be kept around when an error is already
queued or when the service has been stopped.
So, add function that allows to override queued messages based by their
type that follows this policy:
- Messages coming from different services are always preserved in
their original order.
- Messages (from the same service) with a priority equal or higher than
the last queued one are preserved.
- Messages matching completely the last queued are dropped in favor of
this one.
gdm: Keep messages in queue until we've not fully processed them
It can be convenient to get the currently showing message in order to
replace or remove it in case it's not needed anymore.
So simplify the message queue handling by only depending on a single
local variable (_messageQueue) and redefining hasPendingMessages
depending on its content.
Now messages are kept in queue till they are not fully processed and the
first message is always the one currently shown.
gdm: Compress fingerprint failures events using a timeout
When a fingerprint failure event happens we may also soon receive a
conversation-stopped event with an error message (such as in the case
we hit the MAXRETRIES value), but this is going to be ignored in case we
are too quick in consider the first failure a verification-failed event
because that implies disconnecting from all the events and then ignoring
such signals.
To prevent this, add a small timeout before failing the verification so
that if we get a further event we will process it.
gdm: Don't try to retry authenticating when the service is unavailable
In the case a service is not available (as it can be in the fingereprint
case when a supported reader is available but has not enrolled prints)
we were trying indefinitely to restart it, however this can lead to
troubles since commit 7a2e629b as when the service conversation was
stopped we had no way to figure out this case and we'd end up to
eventually fail the whole authentication.
However, in such cases the PAM services are expected to return a
PAM_AUTHINFO_UNAVAIL and gdm to handle it, emitting service-unavailable
signal.
So connect to ::service-unavailable and keep track of the unavailable
services so that we can avoid retrying with them.
In case such service is not the foreground one, we can just silently
ignore the error as we did before commit 7a2e629b, without bothering
failing the whole verification.
In case we got a valid error message on service-unavailable, we also
show it, this is normally not happening unless GDM isn't redirecting
here other kind of problems (such as MAXTRIES) which are supposed to
stop the authentication stopping any further retry.

gdm: Fail and restart verification on conversation stopped for all services
Currently when the foreground service conversation stops we increase the
verification failed count and try to start it again, while if a
background service has been stopped we just ignore it.
This is causing a various number of issues, for example in the case of
the fingerprint authentication service, it is normally configured to die
after a timeout, and we end up never restarting it (while the UI still
keeps showing to the user the message about swipe/touch the device).
So, in such case let's just consider it a "soft" verification failure
that doesn't increase the failures count but will cause us to reset the
UI and try to restart the authentication (and so the affected service).
authPrompt: Bump the user verifier timeout when wiggling the message
Wiggle may make the error message to be visible for less time so provide
the auth prompt an API to increase the timeout to be used for showing a
message in some cases.
This could be reworked when we'll have a proper asyn wiggle function so
that we could just make the user verifier to "freeze", then await for
the wiggle transition to complete and eventually release the verifier.
authPrompt: Wiggle error messages coming from the Fingerprint service
When error messages are coming from the fingerprint service they are actual
failures due to an user input in some device, in so in such case we
can highlight this by using a wiggle effect.
This mimics what has been done in gnome-control-center fingerprint panel
and part of [1].
gdm: Expose the source serviceName for messages and verification failures
By giving to the AuthPrompt information regarding the source service
name (and so the ability to know whether it's a foreground service) can
give it the ability to behave differently.
gdm: Count fingerprint authentication failures in fail counter
Fingerprint PAM module can have multiple failures during a runtime
and we rely on the pam module configuration for the maximum allowed
retries.
However, while that setting should be always followed, we should never
ignore the login-screen's allowed-failures setting that can provide
a lower value.
So, once we have a fingerprint failure let's count it to increase our
internal fail counter, and when we've reached the limit we can emit a
verification-failed signal to our clients.
As per this we need also to ignore any further 'info' messages that we
could receive from the fingerprint service, as it may be configured to
handle more retries than us and they might arrive before we have
cancelled the verification session.
gdm: Increase the verification failed counter once we've a failure
Decouple the verification failure count increase from
_verificationFailed as there are some cases in which we may want to
increase it without emitting a verification-failed signal.
When the login/lock screen is shown the error messages for background
services are always ignored.
However, in case the service is the fingerprint authentication method
we still want to be able to show error messages to inform the user
about what failed, and eventually that the max retries (that may be
different from the login screen configuration) has been reached.
This handles partially the design issue [1] related to the login/lock
screen fingerprint authentication.
Eventually we want to use pam extensions to use clearer and parse-able
messages, however in the case of the fingerprint service we can be sure
that the fprint PAM module will only send errors on auth failures.
ShellUserVerifier: Add method to check if the service name is fingerprint
We have multiple places where we check if we're handling a fingerprint
event, so let's add a common public function so that it can be used also

of whitespace); clearing the input field and pressing Enter becomes a
quick way to jump back to the end of the history. (The current history
item is not overwritten if the input is empty.)

now responsible for trimming the input and deciding that it shouldn’t be

skipped updating the history if the entry was empty.)
Since both users, runDialog and lookingGlass, also need the trimmed
input for other reasons – runDialog to avoid issues when interpreting
the command as a file path (if it can’t be executed as a command),
lookingGlass to decide whether a command should be run at all – have
addItem return the trimmed input. (runDialog and lookingGlass are not
yet changed to take advantage of this – that will be done in separate
commits.)
gdm: Restart only the service that failed at verification-failure
When verification failed using a specific authentication service we're
currently restarting the whole user authentication system, which leads
to lots of unneeded operations (reinitializing a new user verifier proxy,
restarting all the gdm workers with the relative PAM modules and so on).
And this makes also debugging of login problems more complicated, given
we're cluttering the journal with repeated data.
However, at reauthentication failure GDM has already set up for us an
user verifier that we can use reuse to start only the service that had a
failure. So when possible, just start a new service instead of rebooting
the whole authorization process.
gdm: Ensure we cancel all the previously running services on auth retry
When retrying the authentication we should make sure that all the
previously initiated services are stopped in order to begin a new
authentication session with all the configured services.
Unfortunately at the current state we only dispose the currently used
user verifier, but we don't make it to stop all the relative gdm workers
and then they'll stay around potentially blocking any further usage of
them (as it happens with the fingerprint one, that has unique access to
the device).
So, cancel the currently running authentication before starting a new
one if we're explicitly retrying.
gdm: Do not fail the whole authentication if a background service failed
In case a background service such as the fingerprint authentication
fails to start we'd just mark the whole authentication process as
failed.
Currently this may happen by just putting a wrong password when an user
has some fingerprints enrolled, the fingerprint gdm authentication
worker may take some time to restart leading to a failure and this is
currently also making the password authentication to fail:

Given that background services are ignored even for queries or any kind
of message, we should not fail the authentication request unless the
default service fails.
gdm: Disconnect user verifier signals on destruction and verification failed
When a verification session has failed we may want to wait for the user
to have completed all the waiting queries and to have read all the
incoming messages, however during such time an user verifier should
not be allowed to queue further messages to the UI, as we're about to
completely stop the identification or start a new one.
Unfortunately this is not true because we're still connected to the
identifier signals, and so we may still show messages.
This is particularly true when using the fingerprint PAM module as it
may restart the authentication while we're in the process of stopping
it.
So, keep track of all the signals we've connected to, and disconnect on
verification failed and during cancel/clear operations.
gdm: Don't try answering query if the user verifier has been deleted
Answering a query may be delayed to the moment in which we've not any
more messages in the queue, however this case can also happen just after
we've cleared the UserVerifier and in such case we'd have nothing to
answer, but we currently throw an error:
JS ERROR: Exception in callback for signal: no-more-messages:

cancellable and checking whether it is still valid before trying to answer
a query or do a delayed action.
gdm: Limit verification cancellations to be conform to allowed-failures
As per previous commit the user can cancel an ongoing authentication via
Escape key and that will always send the user back to the clock view in
lockscreen or user-selection view in login prompt.
However, we can be a little more permissive and don't switch view to be
able to restart the authentication without further action.
To avoid this to be abused though, we consider the user verification
cancellation via escape key to be a "soft-failure", so once the
configured "allowed-failures" gsettings value has been reached, we'd
just act as before, ignoring any further request (until we don't get
back to the user auth view).
In this way we still make brute-force attacks harder to do, while still
giving the well-behaving user some ability to fix mistakes.
authPrompt: Handle Escape key to cancel ongoing verification
Escape key is supposed to cancel a verification, however if the user
already hit Enter to begin the authentication the Escape key won't work
until the verification completed.
This may be quite inconvenient when an user did a typo while writing and
wants to cancel the already started auth.
So, while authenticating (or in general while the entry is unsensitive)
give the key focus to the authpromt itself so that we can still get the
input events and cancel an user action.
authPrompt: Don't begin a new authentication session on lockscreen cancel event
When a cancel event in the user lockscreen happens we first emit a reset
signal and immediately a cancelled one.
This lead to start a new gdm worker for each enabled authentication
method and then immediately to stop it.
As per the previous commit, we don't have anymore dangling gdm workers
around, but still we should not even start a new one in such case.
So, when the user explicitly cancelled the authentication session, first
emit a cancelled event and only emit a reset event with a begin request
if we are outside the lockscreen.
gdm: Cancel user verification on UserVerifier destruction
When we cancel an user authentication via Escape key or cancel button on
AuthPrompt we reset the view and we emit a 'cancelled' signal that leads
to destroying the auth prompt and the user verifier.
However, the verifier may still have an operation in progress and its
completion may take some time (as in the case of gdm-fingerprint), but
we just leave the gdm worker running until its pam module completes
(potentially never) clearing and disposing its handle.
So, instead of just clearing the verify, actually cancel and clear it.
In case the user verifier is set, clearing the relevant data will happen
anyway as part of the cancel() call.
Ideally this would have been handled by gdm itself, but unfortunately we
can't fix it there because the verifier itself is a class generated by
gdbus-codegen, so we can't handle this automatically on disposal nor we
can automatically monitor when the caller proxy is stopped on our side.

workspace: Always leave overview when in app grid state
The behavior of workspaces is different depending on whether
the overview is in window picker state, or app grid state.
When in window picker state, clicking on adjacent workspaces
should only activate them, without hiding the overview; and
clicking on the active workspace hides the overview. When in
app grid state, clicking on a workspace must always hide the
overview.
Pass the overview adjustment to Workspace, and leave overview
if the overview state is bigger than WINDOW_PICKER.
workspacesView: Interpolate against relative workspace boxes
The overview transition consists of getting the initial and final
states of the overview adjustment, derivating various other internal
states from them (such as the fit mode, opacities, translations, etc),
and finally interpolating the allocation boxes.
When interpolating between the fit mode, WorkspacesView uses the current
allocation box to derivate the SINGLE and ALL fit mode boxes. However,
that creates a curved path during overview transitions. What we really
want to do here is calculate the fit mode box relative to the corresponding
overview state. For example:
+----------------+----------+------------------------+
| Overview State | Fit Mode | Workspaces geometry |
+----------------+----------+------------------------+
| HIDDEN | SINGLE | Cover entire screen |
| WINDOW PICKER | SINGLE | Between minimap & Dash |
| APP GRID | ALL | 15% screen height |
+----------------+----------+------------------------+
Using the table above as the reference, when the overview transitions
between WINDOW PICKER and APP GRID, we must interpolate between
(SINGLE fit mode @ between minimap & Dash) and (ALL fit mode @ 15% screen
height). That way, we always interpolate the final boxes, which corrects
the odd path that workspaces follow during this transition.
Make the WorkspacesView of the primary monitor use these cached boxes
when the overview is in the middle of a transition, and the fit modes of
the initial and final state differ, to calculate the workspaces positions.
workspacesView: Use calculated workspace state for progress
It works just like before, except that this has the nice side effect
of not changing the workspace mode when leaving the overview from
the app grid state.
Move AppDisplay, WorkspacesDisplay, and ThumbnailsBox from ViewSelector to
ControlsManager. This allows to always allocate the correct size for AppDisplay,
and will enable for a plethora of further improvements. The end goal is to
completely remove ViewSelector, and let ControlsManager handle the layout of
everything that's visible in the overview.
For now, replace the apps page with a dummy actor in ViewSelector.
Adjust various callers around the codebase to not access the ViewSelector
directly from the overview anymore.
Bind the opacity of the primary workspace to WorkspaceDisplay's opacity. This
allows removing the parent opacity hack in place, which will be done by the
next commit.
viewSelector: Move 'toggle-applications-view' to ControlsManager
Move the shortcut handling into ControlsManager, and reimplement
the callback in such a way that it behaves correctly with the
current overview machinery.
Now that Overview is able to ease into any state, be it window
picker or app grid, we can move this ViewSelector method to
Overview itself, which is its rightful place to live.
Remove ViewSelector.showApps(), and make all callers call
Main.overview.show(ControlsState.APP_GRID). Also make sure the
show apps button is correctly toggled.
overivew: Propagate target state when animating to overview
Next commits will requires ControlsManager to animate to different
states, depending on how Overview is called. Add a new 'state'
parameter to ControlsManager's, and OverviewActor's animateToOverview,
and Overview.show().
Remove Workspace.zoomTo/FromOverview(), they're unused now. Rename
everything up to ControlsManager to prepareToEnter/LeaveOverview(),
since these classes don't run the animation anymore.
workspacesView: Derive workspace mode from overview state
WorkspacesView uses the floating layout when the overview is in window
picker mode, and the session layout when the overview is in app grid
mode. Up until now, the fit mode adjustment was used to derive the
workspace mode, but it is incomplete as it doesn't have the full range
of workspace states.
Make ViewSelector cascade the overview adjustment to WorkspacesDisplay,
and use the overview adjustment itself to derive the workspace mode.
Extra workspaces don't have to account for the fit mode, and thus are
basically a clamp(state, 0, 1) of the overview state. However, don't
call animateTo/FromOverview() anymore, since they ease the workspace
mode adjustment.

workspacesView: Add primary view to workspaces display

While the workspaces view on the primary monitor *appears* as part of
the overall overview hierarchy, this hasn't actually been the case
until now. We synchronized its size and (stage) position to match
the workspaces display, but actually kept in a separate layer for
the transitions to and from the overview.
But now that the new layout manager slides out completely during the
overview transitions, the workspaces display starts out covering the
entire work area, which is exactly what we need for the transition.
So finally stop faking it, and actually make the primary workspaces
view a child of the workspaces display.
overviewControls: Ease main adjustment when animating to/from overview
Instead of delegating it to ViewSelector, make the transition to and from
overview ease the main state adjustment.
This commit temporarily breaks these animations, but on the other hand
introduces an important feature: ViewSelector is always allocated to the
actual size. This will finally allow for adding WorkspacesView as a child
of WorkspacesDisplay, and finally remove the actual geometry hack, which
is what next commit is about.
Instead of directly accessing ViewSelector and calling these methods
there, cascade the calls to OverviewActor, ControlsManager, and finally
ViewSelector. Also move the opacity transition to OverviewActor.
Currently, ActivitiesContainer reacts to showAppsButton and
transitions between app grid and window picking states on
its own. In the future, we want full control over this.
ControlsManager already has a state adjustment that represents
all possible overview states. Propagate this adjustment up to
ActivitiesContainer, and use it to drive the transition.
This requires moving the callback to the showAppsButton to
ControlsManager, since now it control the state adjustment
itself, not ActivitiesContainer's adjustment.
