This patch changes the way of how the client-selected sub directory is
communicated to the server. The former opaque session argument is now
passed as last label element, which allows for the flexible tweaking
of this argument by init's session-routing and label-rewriting
mechansims. In particular, it alleviates the need for creating chroot
component instances.
This change requires the following four adaptations at the
configuration level:
- Each file-system session request must now carry a path starting
with / as last session arguments. Hence, <vfs> <fs> nodes that
feature a 'label' attributes must extend the attribute value
with " -> /". For <fs> nodes with no label attribute, "/" is
used as last label argument by default.
- For matching session-routing rules at init's configuration,
the matching of full labels should be replaced by 'label_prefix'
matches, excluding the last (path) argument.
- Wherever a label of a file-system session is rewritten by using
init's 'label' attribute of a <parent> or <child> target node,
the new attribute 'identity' should be used instead. This replaces
the identity part of the label while preserving the client's
directory argument.
- Analogously to the matching of session-routing rules, server-side
policy-selection rules that formerly matched a concrete 'label'
must be changed to match a 'label_prefix' instead.
As a good practice, 'label_prefix' values should end with " ->" if
possible, which clearly delimits the identity part of the label
used by the matching.

This patch adds the feature of moving and resizing windows by clicking
anywhere within a window while the global window-management key is held.
Depending on the position within the window, the click is interpreted as
click on the title (when clicking at inner 50% of the window, or as a
click on the border (when clicking at an area nearby the window
boundary).
This mode of interaction requires more flexibility of the handling of
key sequences. The formerly hard-wired handling of the drag and drop as
response to BTN_LEFT events does not suffice. Therefore, this patch
moves the driving of the drag-and-drop state to the config level by
introducing the actions "drag" and "drop"
Fixes#5403
This patch moves the formerly hard-wired drag-and-drop handling
to the configuration level by introducing the actions "drag" and "drop".
To aid the robust handling of release events matching their
corresponding press events, the patch refines the policy-matching of the
current combination of keys against the hierarchy of <press> and
<release> nodes. If no policy for a concrete combination exists, a
release event also considers the policy of its matching <press> node.
This way, the regular drag-and-drop rules can be expressed as
<press key="BTN_LEFT" action="drag">
<release key="BTN_LEFT" action="drop"/>
</press>
This also works when releasing BTN_LEFT while pressing additional keys,
for which no policy exists.
With this change, the layouter supports the matching of multiple key
sequences instead of only one, thereby supporting multiple actions at
once and allowing for decoupling different user interactions in the
configuration.
Issue #5403
To accommodate multi-monitor window management, the window-layouter
rules must be extended. By renaming the rules file to a version number
reflecting the date of change (24.12), we prevent the loss of
window-layout state when switching back and forth between different
versions of the window-layouter.
The default rules contain now the definition of three displays
("primary", "secondary", and "ternary") and map 3 screens to each
display.
Issue #5390
The new 'action' attribute values can be used to realize the
keyboard-based assignement of windows to screens. The "pick_up" action
(on a key press) selects the focused window to be held at the current
position until the "place_down" action is issued (by a key release).
While the focused window is held, "screen" actions can be executed
taking the picked up window to the selected screen.
Issue #5390
This patch restricts the focus switching via the keyboard (Super-Tab) to
windows located at visible screens.
Should the currently focused window become invible, switch the focus to the
most recently focused visible window.
Issue #5390
Replace the use of pointers and the copying of XML nodes by the 'with_'
pattern. Use plain struct where appropriate, replace constructors by { }
initialization. Use C++20 function template syntax. Replace accessors by
public constants where possible. Follow 'from_xml' convention. Follow
usual 'Action' interface naming.
Issue #5390
This patch enables the user to interactively change the assignment of
windows to screens. For screens visible side by side in a multi-monitor
setup, one can now move a window from one screen to another by dragging
the window title. When using screens as virtual desktops on one display,
a window can be moved to another screen by switching the screen (by
pressing a key matching a desired screen) while the window is dragged
with the mouse. So the user can drag the window between virtual desktops.
Issue #5390
This patch allows the user to drag windows from one target area (i.e.,
display) to another whereas the resizing of windows is restricted to
the window's original target area. The latter point is important to
ensure that the window's resize handles remain reachable at all times.
Issue #5390
This patch changes the window-layout format to support the rectangular
clipping of windows at screen boundaries. The new <boundary> node defines
the clipping boundary for the windows listed within the node. Boundaries
are expected to be disjoint. In the example below, the "vbox" window is
placed partially outside the screen area of "screen_2".
<window_layout>
<boundary name="screen_1" xpos="0" ypos="0" width="640" height="480">
<window id="1" title="launchpad" xpos="10" ypos="140" width="400" height=">
</boundary>
<boundary name="screen_2" xpos="640" ypos="0" width="800" height="600">
<window id="2" title="vbox" xpos="520" ypos="52" width="800" height="600">
<window id="3" title="terminal" xpos="650" ypos="72" width="500" height="400">
</boundary>
</window_layout>
The layouter uses boundaries to restrict the visiblilty of windows to
their respective target areas.
Until now, Sculpt relied on the fact that the window-layout ROM had the
same structure as the resize-request ROM. With the addition of the
<boundary> nodes, this is no longer the case. Therefore, the Sculpt
manager generates a dedicated resize-request ROM now.

The accounting of caps for the UTCB allocation on base-hw puts pressure
on the out-of-ram/caps handling of Create_thread_result in the CPU
sampler. This patch implements the formerly missing error handling.

This exposes makes the dialog API usable for users of Goa. It turns the
former static dialog library to a shared object and accompanied symbols
file, and adds depot recipes for the library and API.
Issue #5409
This allows the window layouter to ensure that input entered after
switching to an empty screen won't be routed to the old focused but
no longer visible window.

This patch fixes the following error message printed by the wm upon the
restart of a decorator.
Error: freeing non-empty slab block"
Error: ID space not empty at destruction time
Fortunately, the error is not critical as the backing store is released
along with the session.
The 'label_suffix=" -> decorator"' rule is weaker than the
more generic 'label_prefix="runtime -> wm"' rule, to the effect that the
decorator is assigned to the "desktop" domain instead of the "decorator"
domain. Replace the 'label_prefix' by the decorator's concrete label
to resolve this ambiguity.
This patch fixes the corner case where a call of 'trigger_gui_sync'
unexpectedly did not result in the execution of '_handle_gui_sync'.
When sporadically called (w/o having installed a period sync handler)
in a time window shortly after a previous '_handle_gui_sync' that just
switched back to sporadic mode, the situation was considered as !idle.
So the 'local_submit' was skipped.
The patch fixes the issue by always issuing a 'local_submit' except when
operating in period mode. The '_gui_sync_enabled' state is now driven
only by '_handle_gui_sync' to make the intent more clear.

config node gracefully. If no mirror is set, ever claim one entry

the UI does not allow to merge one of the discrete modes.

This prevents the potential corner case where the terminal receives input
at a time when the window has no valid size and _text_screen_surface is
not constructed.
When trying to open a file in the Files view with font size set to
Large on 4k screens, the editor's / `text_area`'s `view` child fails to
bump its RAM quota when the editor's default quota is too small.
To mitigate the issue, bump the editor's default quota to 80MiB.
The long-term fix would be for the editor to request more RAM from the
runtime to satisfy the `view` RAM request.

When using the Files view with font size set to Large, the boosted
runtime_view limit of 64MiB is still not enough for 4k screens.
Double the RAM boost limit to 128MiB.

With this commit the fb driver is started on the second CPU on the
MNT Pocket Reform to decouple it from the other components started
on the first CPU during the system's boot-up and mitigates bring-up
issues with this driver that result in an often non-working display.
Issue #5378.
This commit adapts the aperture splitting between the GPU multiplexer
and the display driver where the former now always tries to reserve
32 MiB of aperture space for itself instead of limiting the space
for the display driver. In case the aperture is not large enough
the display driver takes precedence and the GPU service has to make
do with remaining space. In the worst case that renders the GPU
service unusable.
Issue #5377.
When updating a dialog after a prolonged idle time with no active
animatons, the next _handle_gui_sync would wrongly fast-forward
animations for all the frames passed since the last _handle_gui_sync. On
the PinePhone, this effect is clearly visible when switching between the
main section. The GUI jumps from one state to another instead of
transitioning. This patch solves the issue be resetting '_previous_sync'
when waking up from idle.

Large deployments (e.g., using the Falkon browser) can significantly
inflate the RAM quota of depot_rom. When switching the Sculpt storage
target (using the "Use" buttons), depot_rom is restarted. Right now,
however, it retains its (inflated) quota. It is better to reset the
quota to its initial value to free up RAM that thereby becomes usable
for a different deployment. Otherwise, the depot_rom's resources can be
deflated only by rebooting.
When using the fonts_fs, the geometry of individual glyphs can change
potentially at any time, after having obtained font-global constraints
once. In particular, a glyph can exceed the bounding box of the font
cell. The VFS font utility must take safety precautions against such
violations.
Fixes#5374
Swapping a 4k monitor between discrete and mirror mode will consume
temporarily at least 32M * 2 (3840 * 2160 * 4 Bytes), so that the
default value of 64M for the aperture is insufficient in addition to
interal display on a notebook. The commit mitigates that the
i915_gem_evict_for_node unimplemented error does not trigger immediately.
Issue #5356
In setups with 3 or more displays, allow the un-merging of connectors
only for the last mirrored connector. Otherwise, the operation would
implicitely change the order of connectors because the new discrete
connector needs appear after all merged connectors.
Issue #5286
The access-point-list hovered state prevents preseting the available
scan results, which currently can happen unintentionally. This commit
hot-wires the hover handling and thus will always show and update the
list. New scan results are received every few seconds and it could
happen that the list changes while the user selects a network (that's
what the original implementation guards against).
Issue #5369.
This patch explicitly handles the unplugging of displays, avoiding the
use of stale connectors for defining the panorama. It also makes the
import of the connectors model robust against intermediate states
reported by the driver (a connector reported as connector but without
any mode), and discards the use of any information of non-present
connectors as merge info.
