cf41f4a527 searchController: Get rid of activePage reference in key handling
Even if activePage has been removed as part of commit 27627bd40, we've
still a reference of it in key press handler.

Given that there's no anymore an active page to redirect input to,
remove these references, so that can be handled in the proper view to
implement key-navigation.

c01973055f 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.

b74900b3a3 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.

45a5171a95 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.

1cc20ca6b6 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.

ef10bb6229 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.

9ecc1a4cd7 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.

1ee9278786 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.

1bd2b0123e windowPreview: Consider chrome overlaps when offscreening for opacity
The icon and close button might be overlapping the window actor but
were not considered in has_overlaps() which gets used to decide whether
to offscreen the actor for transparency. Since currently the icon is
visible when the preview is dragged and the whole actor is turned
transparent, the opacity will not be applied to everything as a whole
but the child actors individually. This leads to the window becoming
visible behind the icon.

8d5fb73695 workspacesView: Don't invalidate allocation before using it for gesture
Calling startTouchGesture() on the workspacesViews can change the
visibility of the workspaces if not all of them are already shown, such
as when there are more than 3 workspaces or for 3 workspaces if we are
not on the central one. This invalidates the allocation and the width
used as distance for the gesture would become 0, resulting in drag
gestures immediately jumping to the first or last workspace due to a
division by 0.

7a2e629bd0 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).

6ccd289691 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.

53db4b99b8 gdm: Always show fingerprint error messages
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.

bbf1fc28ca lookingGlass: Let history trim input
Checking whether the item is empty is now the history’s job, per the
previous two commits. The history also trims the input for us.

The effect of this is that we call _history.addItem(), and thereby move
to the end of the history, even if the input is empty (or consists only
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.)

d31f805817 history: Trim input and ignore if empty
This ports the runDialog changes of [1] to the underlying history
component, where they can benefit looking glass as well: the history is
now responsible for trimming the input and deciding that it shouldn’t be
stored if empty. (Note that _setPrevItem and _setNextItem already
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.)

829a096ba1 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.

0ccb8e27d4 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.

c8bb45b41c 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.

7e77881717 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.

3e96952fde 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.

b916df1110 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.

c0a4d90847 overviewControls: Limit Dash height to 15% of the overview's
Back when the Dash was vertical, the size of each item was calculated
solely based on the available height. After making the Dash horizontal,
this was swapped by the available width. However, when the height of the
Dash decreases, the current code results in never scaling them up ever
again.

Fix that by making ControlsManagerLayout explicitly pass the maximum Dash

bf1fa3879f 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.

d221215ab6 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.

Boy, does this commit feel good.

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.

view a child of the workspaces display.

10cafc55c1 swipeTracker: Rework end point calculation
Previously we used a bunch of heuristics for this. We checked if velocity
was directed towards the nearest snap point and its value was larger than
a threshold. If it is, we completed the swipe, otherwise we cancelled it.

This was good enough at the time, because this code was originally written
for back/forward swipe. Since then, the swipe tracker was extended to
handle arbitrary snap points and not just 0 and 1, or -1 and 0, depending
on text direction. After that it was iterated on, but never significantly
redone.

This worked well enough, but had two problems:

1. In some cases, notably overview, it may be wanted to be able to swipe
   through multiple pages at once. This wasn't really possible because we
   always picked the adjacent snap point.

2. Since we can't do that well, we want to restrict swipes to one page at a
   time. It was done in a rather hacky way by clamping the position into
   [-1, 1] range from the place where we started the swipe. This works
   if we start the swipe from idle position, but if an animation was
   already going, the range would be clamped to arbitrary values, and very
   likely containing only one snap point, which we already swiped past at
   this point. In this case, finishing the swipe would cancel it regardless
   of velocity. This means that if one tries to quickly move through
   carousel pages via swiping, half of the swipes will be inexplicably
   cancelled.

We'll use the deceleration formula from
https://medium.com/@esskeetit/how-uiscrollview-works-e418adc47060#10ce
to calculate then projection point, then pick the nearest snap point and
calculate the duration as we did before. It works well enough for short
distances, but has two problems:

1. It caps the maximum distance at a pretty low value - about 5 pages in my
testing.

2. With how we pick the nearest snap point, it's too easy to accidentally
cancel the swipe,

To combat the first problem, we can modify the curve: only use linear
function at small distances, and smoothly transition it to a parabola
further.

For the second problem we can add two special cases: first, if the swipe
ended up between the initial snap point and the next one, we always prefer
the latter. Second, a good old velocity threshold for cancelling.

We'll also use a slightly smaller deceleration value for touchpad: 0.997
instead of 0.998.

Now that we can pick any snap point, the [-1, 1] clamping doesn't make
sense anymore, so instead let's replace it with a more flexible
mechanism: if we're near a snap point, pick its adjacent snap points.
Otherwise, take the two nearest snap points, and take their adjacent
snap points. This way we have 3 snap points to choose from when
starting a swipe from an idle position, and 4 if we start during an
ongoing transition.

This way, if we've just swiped from snap point n to n+1, the transition
will pick snap points n-1, n, n+1, n+2 and if we swipe again, we will
likely land on n+2. During that transition, if we swipe again, it will
likely have already passed the snap point n+1, so this time the available
snap points will be n, n+1, n+2, n+3, so we can swipe again and it will
still complete, and so on.

This will make it easy to allow multi-page swipes as well, by just
removing the clamping.

cf87ab04aa swipeTracker: Calculate velocity using scroll history
In some cases we may get anevent with very low delta at the end of the
swipe. While we can't completely ignore them, we can smooth them using a
scroll history, similarly to what GTK kinetic scrolling does: keep track
of the last 150ms of events, and sum their deltas when calculating the
velocity.

The logic is based on what GTK does in GtkGestureSwipe and
GtkEventControllerScroll.

824cdc9177 fingerprint: Use makeProxyWrapper for fprintManager
The reason this wasn't using the Gio.DBus.makeProxyWrapper() convenience API is that it passes custom flags to the proxy, and that wasn't supported by the wrapper at the time.

As this is now possible, this commit migrates us to the new API.

7bea63ae4b runDialog: Don’t treat empty input specially
Let empty input result in an error, just like other invalid commands
(bad syntax, nonempty whitespace, etc.). GLib already has an error
message “Text was empty (or contained only whitespace)” which it shows
for whitespace-only input, so letting that message apply also to empty
input makes sense.

This requires some tweaks further down the file to avoid interpreting
empty input as an empty path (relative to the home directory) and then
opening the home directory.

29e2b15236 data: Rename custom close icon
Resource icons are added to the fallback icon theme, so they won't
get used if a matching icon is found in the configured theme.

That includes fallback names, so Adwaita's "window-close-symbolic"
takes precedence over "window-close-24-symbolic" in hicolor.

Fix this by using a custom name for a custom icon.

c61e1e5c2c mpris: Hide unused elements to leave more space for the title
The Message class this is derived from unconditionally adds a close
button with 0 opacity that only gets shown on hover for messages that
can actually be closed. The MPRIS MediaMessage however can never be
closed and having a close button can cause the title to be cut short
unexpectedly.

Similarly the secondary text which other notifications use to display
the notification time is always left empty here as well.
