The X11 protocol uses 16 bit integers for width/height but we use
32 bit integers everywhere else in river. Make sure that values outside
the range of a 16 bit integer don't cause river to crash with an
assertion failure.
I think that coordinates outside the range of a 16 bit integer could
theoretically be reasonable with tiled high resolution displays in the
future. I doubt they ever get used in practice today but at the same
time we can't allow an errant layout generator to crash river.
We must clean up the user data of the wlr_surface for layer surfaces and
lock surfaces as fromSurface() may be called (e.g. by the idle inhibit
implementation) after the scene node has been destroyed but before the
wlr_surface is destroyed.
There is no FreeBSD tarball from ziglang.org and FreeBSD itself has not
yet updated their Zig package to 0.12.0. This commit should be reverted
when a good way is found to obtain Zig 0.12.0 for the FreeBSD CI.
This assert is incorrect if Xwayland is enabled and an Override Redirect
window steals the keyboard focus from the parent surface.
It also seems likely to be hit if a Wayland client attempts to use a
pointer constraint on a subsurface. I don't think a pointer constraint
on a subsurface is likely to work entirely correctly and I don't know of
any Wayland clients that try such a thing. We can't let them crash river
by trying though.
Currently if a second keyboard input device is created river will send
a wl_keyboard.leave event immediately followed by a wl_keyboard.enter
event. This serves no purpose and can confuse clients, in particular due
to fctix creating/destroying virtual keyboards on focus change.

Currently if a client commits a geometry with a different x/y value but
does not change the width/height we might not update the clip
coordinates of the surface tree, potentially causing part of the surface
to be unintentionally clipped off.
To fix this, check for change in geometry x/y as well as width/height on
commit if the client is not currently part of an ongoing transaction.
Firefox for example it seems may respond to a configure non-atomically
with multiple commits:
1. commit new buffer and new geometry of a new width/height.
2. commit again with the same width/height but a new geometry x/y.
I don't think this is technically a bug but it doesn't seem like the
most efficient way to do things. I think this may also cause imperfect
frames. In any case, this should no longer cause river to crop off part
of firefox's surface.
It seems layer-shell clients such as waybar can commit bogus exclusive
zones larger than the width/height of the output. While this client
behavior is questionable at best, it must not cause river to crash or
otherwise misbehave.
Therefore, close layer surfaces causing the usable (not exclusive zone)
area of an output to be reduced below half of the width/height.
Also remove the redundant URL in the footer and the redundant
"General Commands Manual" text (scdoc adds that by default based on the
section it seems).
The correct way to do this would be to use the max-width css attribute,
but codeberg seems to strip that when converting markdown to html.
The new value of 600em looks almost identical to 50% on large screens
and looks a lot better on small (mobile) screens.
Currently if we disable an output due to a wlr-output-power-management
protocol request we do not update Output.lock_render_state properly.
This is fine if the output is also re-enabled using the
wlr-output-power-management protocol but causes an assertion failure
if it is re-enabled using wlr-output-management instead.
Also clean up this code a bit, it's no longer necessary to split these
one line functions out into separate files as Zig's conditional
compilation support has improved since these functions were originally
written.
This field being nullable at all is code smell. I think what needs to
happen here long term is for a proper separation of "window management
output" and "physical output" as concepts and integration outputs into
the transaction system.
That's a much larger change and I don't want to cause that amount of
code churn just before a release though.
This logo is based on original raster images designed by Karl Felix
Schewe (@kardwen on codeberg/github). I created a modified svg version
from scratch in inkscape. I've included several variations (with text,
with text and a background) for various use cases.
The versions with text use the Dongle font [1] which is released under
the OFL and therefore free for us to use in the logo without
acknowledgement according to [2].

This was dropped from 200ms to 50ms in 4a65af66. However 50ms seems
to be a bit too short in practice. I often hit ugly frame imperfection
do to timeouts when toggling mpv between a small floating window and
fullscreen for example, even on a relatively beefy desktop computer.
This only happens while the video is playing in mpv, not while it is
paused. I believe this is due to mpv ignoring the compositor's hints for
when to render a new frame entirely while playing a video. It instead
renders at the framerate of the video being played, even if the
compositor requests a change in size. This isn't great but seems
unlikely to change [1].
Overall, hitting 100ms timeouts subjectively doesn't feel anywhere near
as sluggish as hitting 200ms timeouts and offers better frame perfection
than 50ms timeouts in at least this one example, there are bound to be
others.

Currently we can hit an assertion failure in the putNoClobber() call in
response to the down event since we fail to handle the cancel event.
This commit fixes that issue.
Currently we only support interactive move/resize with the pointer,
touch and tablet tool support are TODO.
Validate the serial here to ensure we don't start a pointer move/resize
in response to the client attempting to start a move/resize with
touch/tablet tool.
This fixes an assertion failure that the pointer's cursor is not hidden
during move/resize, which is how the issue was discovered. Another win
for assertions :)
Sensitive Wayland protocols such as wlr_screencopy and wlr_data_control
(clipboard managment) are now blocked by default inside security
contexts (e.g. flatpak 1.15.6 or later).
User configuration of the allowlist/blocklist is TODO.
If multiple consecutive transaction timeouts occur it is possible for
the SSD borders to become temporarily desynchronized with the size of
the rendered surface.
This is especially noticeable during interactive resize of mpv.
For details on cause/fix, see the new comment in the code.
This fixes a possible assertion failure in Cursor.updateState() when
trying to start move/resize of a xdg toplevel with the timed_out or
timed_out_acked configure_state.
This also generally improves the UX of transaction timeouts as all
state except for the size change is now applied immediately.
There is not any pointer emulation for tablet tool input. This means
that only clients implementing the tablet-v2 protocol will be able to
process tablet tool input.
Tablet pad support is TODO
This assertion does not consider that a view may be visible on an output
despite no view on that output having focus due to a differnt output
currently having focus.
I don't see any clean way to fix the assert, so just remove it.
The current value of 200ms is too long and makes river feel very slow
when it it hit due to an application being very slow/frozen.
The new timeout of 50ms seems to be rarely hit in practice even on
slower hardware such as my old Thinkpad x220. When it is hit the system
feels much more responsive than when the 200ms timeout is hitdespite the
guilty application window potentially being visible in the wrong
location/size a bit longer.
These are by default only enabled for debug builds but give a higher
chance of getting a usable stack trace out of bug reports as Zig's
builtin stack trace dumping code doesn't handle their absence well in
all cases yet. The cost should be negligible as river is not CPU-bound.
I assume that I'm not the only one who has changed/will change their
email over the years of river development, so this seems like a
reasonable thing to have.
