This is a breaking change and replaces the previous
csd-filter-add/remove and float-filter-add/remove commands.
See the riverctl(1) man page for documentation on the new system.
How river currently sets this isn't really in accordance with the spirit
of the protocol. It was originally done this way to get gtk3 windows to
look a little bit better with borders drawn around them. However, I've
come to believe that river shouldn't just ignore standards like this.
The right way to do things would be to either implement the
xdg-decoration protocol for gtk properly or to be pragmatic and accept
some programs are intended to be used with CSD and that's OK.
This brings the behavior closer to what we had before the scene
graph refactor.
The main difference now is that the order has changed from background to
overlay instead of from overlay to background. This ordering seems to
make more sense in the cases I've tested and the old ordering was just
cargo-cult anyways.
Now with 50% less pointer warping!
The new implementation requires the user to move the cursor into the
constraint region before the constraint is activated in order to keep
behavior more predictable.
This replaces the old View.fromWlrSurface function and is more general.
This commit also moves the xdg activation request_activate listener to
Server as it has no reason to be in View.
This is more reliable since it uses absolute coordinates instead of a
relative movement which could cause the cursor position to get out of
sync with the view.
This is the same approach used for resize.
- Move the decision whether a configure should be tracked or not into
the xdg toplevel/xwayland code.
- Only track configures for xdg toplevels with the transaction system
if the dimensions of the view are affected.
Currently we may resize fullscreen views when they become visible/not
visible when switching tags even if their fullscreen state remains
constant. This is suboptimal, and as it turns out also much more complex
to implement.
We need to initialize the geometry on map to ensure the first commit is
handled correctly.
Also we don't care about the x/y of the geometry, only the width/height.
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.
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.
We currently scale the width/height of rectangles based on the scaled
x/y instead of the unscaled x/y. This however leads to inconsistent
width/height due to rounding. Fix this bug by basing width/height
scaling off of the original x/y.
Furthermore, fix a typo where we scaled the height off of the x
coordinate instead of the y coordinate.
If the client commits a protocol error or otherwise crashes before the
session has been fully locked, we currently try to send the locked event
without checking if the client has been destroyed.
This commit adds the necessary if statement.
There's currently a potential race in the implementation that can be hit
during unlocking. This is not a security vulnerability, but it does
cause the compositor to crash due to a failed assertion.
This commit simplifies the code and fixes the race as well as tightening
up the assertions around this state/control flow even further.
Currently we send the locked event after rendering and commit of blank
or lock surfaces buffers on all outputs. However, this is technically
not enough to ensure that the buffers have been presented.
Instead, listen to the wlr_output present event to ensure that no
normal, "unlocked" content is possibly visible.
Currently the spawn-tagmask applies to the currently focused output.
This however means that it is lost if the monitor is unplugged and makes
it hard to set for all outputs.
Change this to make the command apply to all outputs.
This is a breaking change.
It was forgotten to destroy the callback server side object when sending
the destructor event. With the new zig-wayland version, this cannot be
forgotten.
This is nice simplification and allows us to abort startup if the
default xkb configuration (perhaps influenced by XKB_DEFAULT_*
environment variables) is invalid.
Currently the session lock client has no 100% safe way to know when it
is safe to suspend after requesting that the session be locked.
For a suspend to be safe the compositor must have either blanked or
rendered a lock surface on all outputs before suspending. This is
because the current framebuffer on suspend appears to be saved and
displayed again after suspend, at least on my Linux system.
If a new "locked" frame for all outputs is not rendered before suspend,
an "unlocked" frame or frames will likely be briefly displayed on resume
before the lock surfaces are rendered or the screen is blanked.
To fix this, wait until a lock surface has been rendered on all outputs,
or if that times out until all outputs have been blanked, before sending
the locked event to the client.
Resolving this race on the compositor side without protocol changes
is the most effective way to avoid this potential information leak,
regardless of which session lock client is used.
- Remove recommendation of XKB_* environment variables in river(1) as we
now have a dedicated riverctl keyboard-layout command.
- Give an example of how to use and switch between multiple layouts in
the riverctl(1) man page.
This also cleans up the code by using @Type(), eliminating the need
for the argFlag() and boolFlag() functions.
Allowing [:0]const u8 arguments makes this parser useful for
river-control commands as well.
