In commitTransaction() we currently the current view state to determine
whether or not to enable the view's scene tree. However we don't update
the view's current state until after that check.
Moving fullscreen views between outputs now works properly.
A case in which we did not inform the client that it is no longer
fullscreen has been fixed as well.
The race is as follows:
1. Output A commits and sets render state to pending_lock_surface
2. Output B commits and sets render state to pending_lock_surface
3. Output A presents and sets render state to lock_surface
4. maybeLock() does not lock because waiting on output B
5. Output A commits and sets render state to pending_lock_surface
6. Output B presents and sets render state to lock_surface
4. maybeLock() does not lock because waiting on output A
The scene_layer_surface may be destroyed before handleDestroy is called,
which means we can't rely on it to access the wlr_layer_surface in
destroyPopups().
This implementation as it stands is incomplete/buggy and will make
updating to wlr_scene more complex.
It will be reimplemented after updating to wlr_scene is complete.
It looks like having the empty error capture |_| on the else branch of
the if statement causes the else branch to be ignored by the compiler.
This should be a compile error, as the condition of the if statement is
a bool, not an error union.
These new functions allow testing commits without messing up the
pending state of the output and needing to rollback. The new apply()
function also makes the code considerably more concise.
A user reported a crash that only reproduces when preloading a hardened
malloc implementation. From the stack trace, this use-after-free seems
to be the most likely cause. Yay hardened malloc!
Outputs that are part of the layout but currently disabled (e.g. due
to use of wlr-output-power-management) are not correctly handled as
river currently waits for them to present a new locked frame before
sending the locked event.
This new frame never comes however since the output is disabled. Fix
this by maintaining the correct Output.lock_render_state as outputs
are enabled/disabled.
Additionally add missing maybeLock() calls to handle the case that all
outputs in the layout are disabled.
Curently since the struct is semantically passed by value not reference,
there is no guarantee that the `seat_node.data.focused.view == &self`
comparison will work as intended. Since updating to Zig 0.10.0, it seems
this latent bug has now manifested and the focused view title is no
longer sent to the client when it changes.
Fix this by taking the view argument by constant pointer instead.
Instead of stashing the active view and setting Seat.focused to the
Xwayland OR surface when a child OR surface of a currently focused
Xwayland view is given keyboard focus, keep Seat.focused set to the
Xwayland view.
Such Override Redirect surfaces are commonly used for drop down menus
and the like, and river should behave as if the parent Xwayland view
still has focus.
This ensures that the riverctl focus-view next/prev commands continue to
work as expected while a popup is open, the correct focused view title
will be sent over river status, etc.
It's also cleaner to centralize this logic in XwaylandOverrideRedirect
and keep it out of Seat.zig.
Xwayland OR menus may disappear if their parent view is deactivated. The
heuristic and ICCCM input model implemented prior, used to determine whether an
OR surface may take focus, does not cover all menus, so retaining parent view
activation works as a catch-all solution for handling unwanted OR menu focus.
