Commit 152a559e replaced the view pointer in the inhibitor struct with a
pointer to the wlr_inhibitor for application inhibitors. But this was not
changed in the sway_idle_inhibit_v1_application_inhibitor_for_view function.
This caused a bug in the sway tree view where the application inhibitor is
always "none".
This commit makes sure the extents are kept up-to-date, fixes not
damaging the surface if its layer shell-specific state didn't change,
and adds a check if the layer shell-specific state didn't change but the
surface got mapped/unmapped, which could affect keyboard focus.
This prevents sway from extending the desktop to i.e. VR headsets, and makes
them available for DRM leasing.
Non-desktop wlr_outputs will be offered through the wlr_drm_lease_v1_manager
interface for client to lease.
Use fixed titlebar heights. The default height is calculated based on
font metrics for the configured font and current locale.
Some testing with titles with emoji and CJK characters (which are
substantially higher in my setup) shows that the titlebars retain their
initial value, text does shift up or down, and all titlebars always
remain aligned.
Also drop some also now-unecessary title_height calculations.
Makes also needed to be updated, since they should be positioned with
the same rules.
When a layer surface shrinks we need to damage the area it previously
occupied, but we don't know the location of all its subsurfaces in the
previous state, so instead damage a rectangle that encloses the entire
previous extent.
The xdg-decoration protocol allows clients to request whether they want
to use server side decorations or client side decorations. Currently,
sway ignores this and always enforces whatever the server is currently
set to. Although tiled clients cannot be allowed to set borders, there
is no harm in listening requests from floating clients. Sidenote: also
fix an unrelated style error.
There was some unused code-paths for rendering surfaces with an
arbitrary rotation applied. This was imported from rootston.
Since we don't have plans to make use of this, remove it.
render_surface_iterator previously deduced the clip box from an optional
container passed with render data. This causes problems when offsets in
view geometry need to be compensated for in the clip dimensions.
Instead, prepare the clip box in render_view_toplevels where the offsets
are being applied, and compensate for them immediately.
A similar compensation is applied to render_saved_view.

These coordinates contain the all-time accumulated buffer attach point,
which is a way to perform incremental client-side initiated movement of
windows, intended as a way to maintain logical window positioning while
compensating for layout changes such as folding in a left side panel.
This value is not useful for implementing this feature, and break things
if they ever become non-zero. Their inclusion in calculations also tend
to cause confusion.
Remove usage of these coordinates, removing the ability for clients to
move themselves. This may again be supported if a better API is made
available from wlroots.
When an application inhibited idle, a view pointer was stored and a
destroy listener was registered to the wlr inhibitor. As the wlr
inhibitor lives longer than the view, this lead to a dangling view
pointer between view unmap and inhibitor destroy.
Store a pointer to the wlr inhibitor instead of to the view, and look up
the view when needed, which may at any point be NULL. This also allows
for an inhibitor to remain functional if a surface is re-mapped.
If a surface is associated with a sway container, we limit the
destination box to the container dimensions.
Floating views and popups are exempt from this clipping.
In e0a94bee8d, it was believed that if the
container is being rendered, it must have an output.
This turned out not to be the case. When rendering a container, all its
children are rendered, even if the children is positioned off screen and
thus not having any output. This is the cause of the crash in #6061.
This commit introduces a null-check, which fixes#6061.
On server request, we need to send configure events to inform the client
of the new intended size. If the client changes size itself, sending a
configure event will only cause problems.
Use transaction_commit_dirty_client to distinguish between the two
transaction causes.
Currently, various floating-point expressions involving
the coordinates of borders, titlebars and content surfaces
are directly assigned to integers, and so they are rounded
towards zero.
This results in off-by-one distances between these elements
when the signs of their coordinates differ.
Fixed by wrapping these expressions with a call to
floor before the assignment.
When a container straddles multiple outputs, the title bar is only rendered
at the scale of the "effective" output. If the title bar straddles onto
another output with a different scale factor, it was drawn at the wrong size.
In this commit, we take into consideration the scale the title was rendered
at and scale it accordingly so that it appears at the right size on the other
outputs.
This fixes#6054.
To reproduce:
- Open a floating window and a popup that hangs over the bottom or right
- Move the window in the direction of the popup overhang
- The previous position of the popup is damaged, not the new one
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.
Instead, use the state struct for both current and pending.
The transaction system contains a necessary optimization where a popped
transaction is combined with later, similar transactions. This breaks
the chronological order of states, and can lead to desynchronized
geometries.
To fix this, we replace the queue with only 2 transactions: current and
pending. If a pending transaction exists, it is updated with new state
instead of creating additional transactions.
As we never have more than a single waiting transaction, we no longer
need the queue optimization that is causing problems.
Closes: https://github.com/swaywm/sway/issues/6012
Transactions currently wait for all configures to be acked, regardless
fo what they were sent to. This includes views that are hidden in tabbed
or stacked containers. If these views do not ack the configure in
response to a single frame callback, they can cause transaction
timeouts.
Check if a container is hidden before registering the configure serial
and saving any view buffers.
Closes: https://github.com/swaywm/sway/issues/6023
xdg_shell and xwayland handled geometry changes differently despite
needing mostly identical behavior. The xwayland implementation has been
changed to match that of xdg_shell.
The size of a tiled container cannot change in response to new buffer
sizes, so there is no need to commit a new transaction. Instead, simply
recenter the view with the new geometry, leaving the full transaction
flow for floating containers.
We need to use surface_x and surface_y when rendering and damaging saved
buffers as these compensate for views that have been centered due to
being smaller than their container.
Add them to the surface positions on the saved buffer so we have the
values from the time the buffer was saved.
wlr_output_configuration_head_v1_create normally fills out the head
"enabled" field to match the wlr_output state. We overwrite this to also
set the head as enabled if it is only turned off with DPMS.
However, in some cases we may not have a mode for this display, in which
case setting it as enabled will lead to a segfault later on. Therefore,
enabled conditional on the presence of a mode.
Instead of calling wlr_xdg_surface_for_each_popup and then
wlr_surface_for_each_surface, use the new for_each_popup_surface helper
introduced in [1] that does it in one go.

In i3, the workspace_layout command does not affect the
workspace layout. Instead, new workspace level containers
are wrapped in the desired layout and the workspace layout
always defaults to the output orientation.
Currently, when sway sends a configure with some geometry and the
client responds with a different geometry in a commit that acks that
configure, sway ignores the new size. Sway applies the surface
geometry it had requested to the container, not what was actually
committed, in the following transaction.
This change allows any client commit to change its surface geometry,
even if it is a response to a configure event.
Sway maintains a list of pending transactions, and tries to merge
consecutive transactions applying to the same views into one. Given
a pending transactions list on views {A, B, C} of:
A -> A' -> A'' -> B -> B' -> B''
Sway will collapse the transactions into just A'' -> B''. This works
fine when doing things like resizing views by their border. However,
when interactively resizing layouts like H[V[A B] C], we end up with
pending transaction lists like:
A -> B -> C -> A' -> B' -> C' -> A'' -> B'' -> C''
Previously, Sway would not be able to simplify this transaction list,
and execute many more transactions than would be necessary (the final
state is determined by {A'', B'', C''}).
After this commit, the transaction list gets simplified to A'' -> B'' ->
C'', resolving performance problems (that were particularly noticeable
with high-refresh-rate mice).
Fixes#5736.
Xwayland views are aware of their coordinates, so validating transaction
completions should take into account the reported coordinates of the
view. Prior to this commit they didn't, and matching dimensions would
suffice to validate the transaction.
Also introduced `transaction_notify_view_ready_immediately` to support
the fix from d0f7e0f without jumping through hoops to figure out the
geometry of an `xdg_shell` view.
Sway logical coordinates are doubles, but they get truncated to integers
when sent to Xwayland through `xcb_configure_window`. X11 apps will not
respond to duplicate configure requests (from their truncated point of
view) and cause transactions to time out.
Fixes#5035.
i3 shows indicators for the workspace-level pseudo-split, but Sway does
not, as of b977c02. This commit replaces the floating container check
with a call to `container_is_floating`, which has some more robust
checks in place.
Fixes#5699.
My primary issue was IntelliJ IDEA's code suggestion pop-up not returning focus
to the active editing window.
I have spent some time looking at the changes of @Xyene (#5398) and
@RyanDwyer (#2103). I think my proposed change maintains the status
quo for the most part whilst fixing my focus issue.
I have verified that @Xyene's fix for IntelliJ sub-menus still works.
I have done basic testing which consists of:
- Chrome
- IntelliJ IDEA 2020.2.1
- VSCode
- Alacritty
It seems to hold up. I at least didn't see any obvious errors.
Relates to #3007
Instead of listening to both transform and scale events, we can listen
to the commit event and use the new wlr_output_event_commit struct to
decide what to do.
This de-duplicates some of the work we were doing twice when an output
was re-configured.
Depends on [1].

Usually it should be enough to simply not grant a client's
minimize request, however some applications (Steam, fullscreen
games in Wine) don't wait for the compositor and minimize anyway,
getting them stuck in an unrecoverable state.
Restoring them immediately lead to heavy flickering when unfocused
on my test application (Earth Defense Force 5 via Steam), so it's
preferable to grant their request without actually minimizing and
then restoring them once they are in focus again.
Previously, we called output_disable prior to wlr_output_commit. This
mutates Sway's output state before the output commit actually succeeds.
This results in Sway's state getting out-of-sync with wlroots'.
An alternative fix [1] was to revert the changes made by output_disable
in case of failure. This is a little complicated. Instead, this patch
makes it so Sway's internal state is never changed before a successful
wlr_output commit.
We had two output flags: enabled and configured. However enabled was set
prior to the output becoming enabled, and was used to prevent the output
event handlers (specifically, the mode handler) from calling
apply_output_config again (infinite loop).
Rename enabled to enabling and use it exclusively for this purpose.
Rename configure to enabled, because that's what it really means.

Closes: https://github.com/swaywm/sway/issues/5483
If a client commits a new size on its own, we create a transaction for
the resize like any other. However, this involves sending a configure
and waiting for the ack, and wlroots will not send configure events when
there has been no change. This leads to transactions timing out.
Instead, just mark the view ready immediately by size when the client
is already ready, so that we avoid waiting for an ack that will never
come.
Closes: https://github.com/swaywm/sway/issues/5490
The centering logic needs to take borders, titlebars and CSDs into
account. Instead of using the main surface geometry, use the container
and view geometry, which account for this.
During the execution of a resize transaction, the buffer associated
with a view's surface is saved and reused until the client acknowledges
the resulting configure event.
However, only one the main buffer of the main surface was stored and
rendered, meaning that subsurfaces disappear during resize.
Iterate over all, store and render buffers from all surfaces in the view
to ensure that correct rendering is preserved.
This is necessary because some applications (e.g. Jetbrains IDEs)
represent their multi-level menus as unmanaged surfaces, and when
closing a submenu, the main menu should get input focus.
Closes#5347.
Instead of removing the destroy listeners in the output destroy, remove
them in the damage destroy handler. Fixes the following use after free:

With these changes, sway will respect positive exclusive zones of layer
surfaces anchored to one or three sides.
This matches the protocol, which states that a positive exclusive zone
should be respected, "if the surface is anchored to one edge or an
edge and both perpendicular edges". If the surfaces is "anchored to
only two perpendicular edges (a corner), anchored to only two
parallel edges or anchored to all edges a positive value will be
treated the same as zero".
