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.
It seems like the wlr_scene implementation of sending per-surface
feedback is a bit too spammy and can lead to resource exhaustion in
clients in at least some reported cases.
Outputs using the wlr_output_layout auto-layout feature may have their
coordinates update any time an output is added/removed to the layout or
the position of another output in the layout is set.
River currently doesn't keep the scene node coordinates of such outputs
in sync with their position in the output layout, which leads to bugs
with e.g. the cursor not working properly for such outputs.
Currently we update output-management clients based on changes in the
wlr_output_layout struct. However, this is obviously wrong on closer
inspection due to the fact that not all outputs are tracked by the
wlr_output_layout at all times. I think this aproach was originally
cargo-culted from some other output-management implementation and it
needs to go.
Luckily, the solution is quite simple since the only way to configure
outputs using river is through the wlr-output-management protocol. This
means we need to send a new configuration to the output-management
client in 3 cases:
1. An output is created
2. An output is destroyed
3. A wlr-output-management config from a client is applied
Unfortunately, clients in the wild sometimes get the
configure/ack_configure/commit sequence wrong, committing the configured
surface with a size different than the one they ack'd only to later in
separate commit adpat the surface size to that requested by the
compositor.
Improve river's handling of such buggy clients to keep river's ssd
borders and internal state consistent with whatever the clients actually
commit regardless of the correctness of the clients. Log a shame message
for such clients to make me feel better about working around their bugs.
If a view that is currently being destroyed is matched by a newly added
rule river crashes due to an assertion failure.
Fix this and add another assertion to make this precondition more
visible to the users of RuleList.match().
If there is a transaction inflight when an output is disabled then we
must call View.commitTransaction() for any views evacuated from the
disabled output to ensure transaction state remains consistent.
Root.commitTransaction() will not call View.commitTransaction()
for these evacuated views as their output is no longer around.
If a new transaction is started that calls configure() on an xdg
toplevel with a timed_out/timed_out_acked configure_state we currently
leave the configure_state untouched if no new configure is needed.
This can cause an assertion failure in View.commitTransaction() if the
xdg toplevel still hasn't acked/committed by the time the new
transaction completes.
To fix this, update the configure_state as necessary.
All of these API calls checking if the device supports a given option
and checking if the value would be changed are effectively useless.
A quick peek inside the libinput source code shows us that all of these
"setter" functions validate their arguments and return an error if they
are invalid.
Since we don't do anything with the information of whether or not a
config option has been changed or if a config option is even supported
for a given device, all these apply() functions can be simplified to a
single libinput function call.
wlroots implements this behavior with its key press tracking but
continues to forward the events to the compositor. Matching the wlroots
behavior here seems like the best way to avoid strange edge cases and
this is unlikely to ever be an annoying limit in practice.
Also take this oppurtunity to finally refactor away the hasMapping()
function in a way that doesn't sacrifice correctness even when hitting
this 32 key press limit.
Currently configure timeouts hit the "client is buggy and initiated size
change while tiled or fullscreen" code path even if the client is not in
fact buggy. This causes state to get out of sync between river and the
client, and is highly visible as the borders drawn by river no longer
align with the buffer dimensions committed by the client.
This commit fixes this by tracking acks/commits in response to
configures even after a timeout and properly integrating them with the
transaction system.
There are some cases in which a view can end up with a size/position
that places some part of it outside its output. For example, a window
with a large minimum size in a tiled layout that is placed near the
right or bottom edge of the output may extend past the output bounds.
The problem with this is that part of the view outside the output bounds
may be rendered on another output where it does not belong in a multi-
monitor setup.
To fix this, clip the surfaces of the view and the borders to the output
bounds.
Focus may not actually change here so seat.focus() may not automatically
warp the cursor. Nevertheless, a cursor warp seems to be what users
expect with `set-cursor-warp on-focus` configured, especially in
combination with focus-follows-cursor.
It's unclear if this is technically a violation of the protocol or not,
but it makes little sense to do this and many clients in the wild crash
if wl_keyboard.enter is sent before wl_keyboard.keymap.
If our current approch without xkbcommon translation does not match any
mapping on a key event attempt to match the translated keysym as well.
This makes e.g. the keypad number keys (e.g. KP_1) work intuitively as
they may require translation with numlock active.
The reason we stopped doing this in I7c02ebcbc was due to layout where
e.g. Super+Shift+Space is translated as Space with the Shift modifier
consumed, thereby conflicting with a separate mapping for Super+Space.
This should not be a issue anymore though as we now only run a maximum
of one mapping per key event and we attemt to match mappings without
xkbcommon translation before attempting with translation.
It seems to be a bit too early to drop support for this legacy protocol.
Xwayland apparently still relies on it for hardware acceleration as do
fairly recent mesa versions still in widespread use.
wlroots will now load xcursor themes at the correct scale automatically
based on the scale of the outputs where ther cursors are displayed.
Also make the error handling a bit more robust.
This code could allows the view to be focused and urgent at the
same time if the request to activate the view is received just after
the pending focus has been set but before the transaction completes.
This commit leverages the new wlr_scene helper to send custom feedback
per surface rather than using the same default feedback for every
surface. This should allow direct scanout to work more reliably with
multiple outputs for example.
wl_drm is a legacy interface superseded by the linux-dmabuf
protocol. All clients should migrate.
This commit drops support for the protocol which should help find
whatever problematic clients are left in the wild.
If it turns out that this is too soon we can easily keep supporting
wl_drm for a little while longer as wlroots has not yet dropped support
for it.
The protocol states that we must send enter and leave to all text input
objects if the client has created multiple.
Only one text input is allowed to be activated by the client per seat
however.
Currently wlr-output-management config application is broken since the
pre 0.17 code relied on the (now removed) output enable/disable event to
be emitted as part of the state application.
The old code was pretty smelly and hard to understand, I'm glad the
upstream improvements pushed river's code in this directions.
Thanks to tiosgz for prompting me to look at this more closely.
There doesn't seem to be any compelling reason to use the
wlr_scene_output_layout helper, it's simpler to just make the two
necessary SceneOutput.setPosition() calls manually. This will hopefully
be refactored down to a single call eventually as well.
This logic that looked pointless to me while doing the wlroots 0.17
upgrade is in fact important as tiosgz helpfully pointed out.
It was added back in bc610c8b to address an issue. Hopefully the new
comments stop me from trying to break it again :)
The previous commit ended up clamping the accumulated f64 offset to an
integer every frame, losing any sub-pixel cursor motions. This has been
known to cause problems with high polling rate mice in the past.
Return to the same approve the move cursor mode uses to solve this and
accumulate a separate sub-pixel delta.
Currently resizing a window allows moving the invisible "internal"
cursor infinitely far off screen despite the fact that the window is
bounded by the size constraints of the client and by the output
dimensions. This means that attempting to resize past these bounds in
one dimension will result in the "internal" cursor being far out of
bounds and will require an equal movement in the opposite direction in
order to continue resizing.
Exposing this implementation detail of an invisible "internal" cursor
separate from the rendered cursor is of course bad, so clamp it to the
bounds of the resize.
Currently views which are mapped while no outputs are available can
never actually get rendered because they have 0 tags and are stuck in
the hidden stack.
This commit fixes this and they should now be restored when a new output
becomes available.
Such requests currently lead to an assertion failure.
I don't know what changed in nautilus 45.0 that caused it to start doing
this and I probably don't want to know.
This rule action accepts and assigns a set of 32 tags represented as a
32 bit integer just like all of river's other commands handling tags.
Using the singular here is potentially misleading and is also
inconsistent with set-view-tags, etc. which all use the plural.
Sorry about the breaking change for those who use master branch, ideally
I would have caught this before merging but at least I noticed before a
release.
This commit also does a bit of internal refactoring/cleanup of the rules
system.
It is possible for the assertion in PointerConstraint.confine() to fail
if a view with an active pointer constraint is, for example, resized
using a keybinding such that the pointer is outside the constraint
region.
Handle this edge case by deactivating the constraint. The other option
would be to warp the pointer to the nearest point still inside the
constraint region. Deactivating the constraint is far simpler however
and I don't expect this to be a UX pain point.
