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.
When `focus-follows-cursor` is set and the cursor moves onto an output
where no views are present on the currently visible tags, focus the
output itself instead of an individual view.
This is useful e.g. when you want to spawn a terminal on your empty
monitor or switch it to a different tag. Previously such changes would
happen to the monitor on which you previous focus was, despite the
cursor being somewhere else.
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.
Previously new keyboards would not be added to already existing
keyboard groups on (re-)connect. Only during the creation of
the groups themselves were devices added to them. This meant
that only keyboards connected during startup - before the init
is executed - would work with groups in a typical river session.
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wl_drm is a legacy interface superseded by the linux-dmabuf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.
This commit adds a fullscreen rule for configuring
whether the view should be drawn fullscreen on start up.
The actions "fullscreen" and "no-fullscreen" map to the two
possible state of a view and semantically operate on the same
rule list. The behavior of adding, deleting and listing rules
follows that of float and ssd.
This commit adds position and dimensions rules for configuring
the initial position and dimensions of views.
When a view is not matched by any position rules, it is centered
in the avaliable output space matching the current behavior. If
the provided position rule places the view outside of the output,
the view's position is clamped to the output bounds (with respect
to borders).
When a view is not matched by any dimensions rules, no default
dimensions is set by the server. If the provided dimensions rule
exceeds the minimum or maximum width/height constraints of the view,
the view's width/height is clamped to the constraints.
Position and dimensions rules have no effect if a view is started
fullscreen or is not floating. A view must be matched by a float
rule in order for them to take effect.
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.
Currently river only sends the fullscreen state to a maximum of one
toplevel per output at a time and switching tags such that the
fullscreen toplevel is not visible causes the fullscreen state to be
removed.
This may be technically correct, but it causes issues when programs like
firefox trigger animations on fullscreen state change.
This commit returns river's policy here to what we did back in 0.2 and
leaves the xdg_toplevel fullscreen state set regardless of whether or
not the toplevel is currently rendered as fullscreen or if there are
other fullscreen toplevels.
This fixes possible assertion failures when quickly cancelling and
starting a new move/resize. The following steps, take from the bug
report, can currently reproduce the race:
1. Start with a window in tiled mode.
2. Begin resizing the window with your cursor.
3. Send the window back to tiled mode (with a keybind) and quickly begin
resizing it again with your cursor.
Currently if a drag icon is created but the cursor/touch point is not
moved river will render the drag icon at 0,0 instead of the cursor/touch
point location. This fixes that.
This means that interactive resize speed is no longer throttled by the
speed at which the client commits new buffers. Interactive resize speed
is now determined entirely by how fast the pointer input device is moved
by the user.
This may result in more subjectively "choppy" resizes for clients that
commit very slowly, but it should be less sluggish at least.
Previous order was (action, conditions, action argument), current is
(conditions, action, action argument). The old one was an expansion of
(action, conditions), which itself most likely came from the separate
<action>-filter-add commands. On the other hand, the new order keeps
action and its argument together and is in line with the logical flow
(check conditions, apply action).
On shell completions: only bash absolutely needed to be updated. fish
and zsh slightly misbehave regardless of the order.
This goes as close as possible to the behavior before this state was
introduced (keeping the improvement which needed it, 931405ab), fixing
various mis-interactions of keyboard and focus_follows_cursor focus
changes.
The following text is irrelevant to restoring correct basic FFC behavior
and talks about less common scenarios with regards to FFC clashing with
views' input region beyond their geometry, continuing the work done in
931405ab.
Scenario 1: the cursor traveling along a view's border in a "dead zone",
never initiating a focus change. If the focused view has an extended
input region, that area has some functionality (such as client-initiated
resizing); therefore it should be respected and even if another view's
geometry is also under the cursor, focus shouldn't change. In case of
unfocused views, it is a matter of consistency with the focused-view
case. This outcome is also easier to implement, as it doesn't require
any additional code.
Scenario 2: *clicking* such a dead zone, i.e. extended input region (of
an unfocused view). In question is not whether to focus the view (yes),
but whether the focus_follows_cursor_target should be set to the view as
well. Only one case seems relevant to me here, which is when ffc_target
is another view whose geometry is under the cursor, but covered by this
newly-focused view's input region. The most likely action following the
click is resizing the newly-focused view, where a touchpad or faulty
mouse could make the cursor move a bit farther after the button has been
released. I believe that ffc_target shouldn't have been updated, in
order to now prevent focus from skipping away.
(Another variant is me, wondering why the wrong view got focused and
trying to focus the right one using FFC. In that case, however, one
could ask if it's river that misbehaves and whether the application is
really well-integrated into the user's desktop when it provides a
feature they don't desire.)
Not decreasing the counter caused a weird bug where disabling/removing
an output (curiously, it seems to apply only to last active output being
removed) would lock the user out of the session, not letting the
transaction to complete (therefore hiding all views on a newly added
output) and messing up focus.
Fixes https://github.com/riverwm/river/issues/830
As discussed with ifreund on irc. This avoids extra allocation in case
of all_outputs and confusion in case of active_outputs (because with the
Output embedded in the Node, i thought its value was copied instead of
its pointer).
This was accidentally removed in 05eac54b077, which broke
SceneNodeData.fromSurface() for xdg_toplevels.
This means that thing such as xdg-activation and idle inhibit didn't
work since that commit and should work again starting from this commit.
When sending a configure, wlroots will send the same size that was sent
on the previous configure unless a new size is set. If a client resizes
their window itself, the size wlroots has in
XdgToplevel.scheduled will be obsolete and needs to be updated by river.
The previous commit broke handling of keyboard interactive
layer surfaces being created on multiple outputs at once.
This new approach reverts part of the logic change in the previous
commit while keeping the fix for the crash and the new assertion.
Currently if a layer surface is focused and the user focuses a different
output the layer surface remains focused. However, updating focus on
layer surface unmap only considers seats that have the layer surface's
output focused.
To fix this there are 3 approaches I see:
1. Unfocus all layer surfaces on the old output when switching output
focus, focus any layer surfaces on the new output.
2. Disallow switching output focus while a layer surface is focused.
3. Stop caring about output focus when determining which layer surface
should gain/lose focus.
I've taken the 3rd option here as it is significantly simpler to
implement and maintain but still feels reasonably intuitive.
This eliminates cursor jitter entirely during interactive resize.
This also fixes a bug where the xdg-toplevel resizing state was not
cleared if a resize operation was aborted due to a change in view tags
or similar.
Some clients (e.g. mpv) do not respond to configures by committing
buffers of the exact size requested. Instead they may commit a buffer of
a smaller size in order to maintain an aspect ratio or not commit a
buffer at all.
Mixing views that are currently being mapped/unmapped with views that
are stashed during hotplug down to 0 outputs is error-prone and almost
certainly has a bug or two hiding currently.
If a output is removed and added back without being destroyed this must
be reinitialized.
This commit also cleans up the Root.applyPending() calls related to
output hotplug and adds some more logging.
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.
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.
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.
The wlroots rendering API expects colors to be provided with
premultipled alpha but we currently do not parse them as such. This
causes blending with e.g. a transparent border color to be very broken.
The calculation of view.pending.box.x for snap right should be based on
output_width (not output_height).
The inverse applies to view.pending.box.y for snap down.
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.
When focus-follows-cursor is used with cursor-warp, some windows will
get focus before the cursor properly "enters" the window since they have
a larger input-region than their window geometry, this causes the cursor
to be yanked to the middle unexpectedly.
This fix makes it so the focus is only given when the cursor enters the
window geometry.
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.
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.
Warp the cursor to the center of the focused view if the cursor is not
in the bounding box of that view already. This helps the user to keep
track of their cursor when they mostly use the keyboard and the cursor
becomes hidden most of the time, also helps trackpad/trackpoint users.
This reduces the impact of keyboard groups on the Keyboard.zig
implementation and otherwise improves consistency with patterns used
elsewhere in rivers code.
There are also two small changes to the riverctl interface:
- keyboard-group-add-keyboard is renamed to keyboard-group-add
- keyboard-group-remove is added to support removing keyboards from a
group.
The fact that this call is missing is a bug, as the changes made by
arranging the output layers as well as changes to the focus will not be
fully applied.
It is not guaranteed that the next layout_demand event after a user_command
event has the same active tags (for example when there are no views visible).
As an example, a user could trigger a user_command while no views are visible,
then switch to a different tag set which has active views. The active tags of
the previous layout_demand may also be different.
Therefore it is impossible to correctly implement a layout generator which has
user commands apply only to the currently active tag set, which is solved by
this patch.
