The motivation for this change is to simplify the implementation
and remove a massive footgun that is currently present and causing
UB/crashes. If a layer surface is destroyed in arrangeLayers() then
the code in LayerSurface.handleCommit() after the arrangeLayers()
call accesses free'd memory. This is of course possible to fix,
but it's far simpler to loosen up the protocol implementation a bit.
The new implementation is also in line with what sway and the new
wlroots layer shell helper do and is perfectly valid according to
the protocol.
I have encountered a crash (failing assert) if a view specified a fixed
size less than this minimum, and according to ifreund this behavior was
planned to be removed, anyway.
In particular, this fixes a crash that can happen if a client is made
non-fullscreen and then, while that transaction is ongoing, made
fullscreen again.
Notably, we no longer call both wlr_output_test and wlr_output_commit
when applying an output config, which seems to fix or workaround an
occasional crash since updating to wlroots 0.15.0.
Currently river will place the surface at the top or left edge if
opposing anchors are set without a 0 width/height. Instead, center
the surface between the anchors.
We currently don't properly handle xdg surface geometry of the parent,
which causes popups to render partially off-screen in some cases.
GTK4 clients such as easyeffects seem to trigger this issue reliably.
I thought this should be fine as river won't yield to the event loop
when Seat.deinit() is called before the wlroots seat is destroyed, but
a segfault on exit has been reported with a stack trace mentioning
wlr_seat_destroy(). Let's hope this clears that up.
The new code to dedup XcursorManager.setCursorImage() calls for
efficiency currently doesn't handle clients setting the cursor properly.
This commit corrects this oversight.
This patch allows to focus outputs by clicking on the empty background and by
clicking on layer surfaces without keyboard interactivity. This makes it
possible to use the cursor to focus outputs with no visible views.
This also fixes problems with pointer interactive layer surfaces (for example
launchers and docks) on non-focused outputs.
Currently wlroots sends use the drag destroy event before sending the
wl_data_device.leave event to the client, which makes things a bit
awkward. My patch fixing this has been merged to wlroots master so we
can remove this when upgrading to wlroots 0.15, but until then this
workaround will fix the issue.
This doesn't really matter that much as unrecognized options will still
trigger a help message to be printed, but -h is much more standard so
lets make the predictable choice here while sticking to only single '-'
flags.
mpv for example has key bindings to set the window size to a multiple of
the video resolution. This is a valid use case for client-size resizing
of the view and river should respect this if the view is floating.
This greatly improves the UX of this feature, as views moving under a
stationary cursor (as happens during the zoom command for example) will
no longer trigger focus change.
Currently the implementation treats the x/y coordinates of
View.State.box as layout coordinates instead of output-relative. This
causes issues when using an output not at 0,0.
Layout generators are generally pretty fast. The timeout is only reached when
the generator is faulty / stuck. In that case, freezing for 1 second is simply
bad UX.
Currently the view destruction sequence is started as soon as a view
is unmapped. However, this is incorrect as a client may map the view
again instead of destroying it.
Instead, only start the view destruction sequence when the underlying
xdg toplevel or xwayland surface is destroyed.
