Add more sophisticated code to handle the primary node disappearing.
Also overhaul the selection logic to respect our allow/deny-list and
prefer devices with built-in connectors before using the boot gpu.
This will also allow triggering a primary node switch at runtime
for debugging purposes in the future.
Previously, a click on a client like squeekboard would give keyboard
focus to the window behind it, if any.
If we are in the input region of the layer surface, we shouldn't give
keyboard focus to the surface behind it on click. And should just leave
the focus unchanged. Returning `None` here seems to be correct.
Previously, `Frame` was stored in KMS frame udata, but in some cases the
udata was dropped without a capture happening, and `Frame` did not
implement `Drop`, so `fail` was never sent.
Instead, rename `DropableFrame` to `Frame` and `Frame` to `FrameRef`, so
we can have a single instance of `Frame`, that will send `fail` on drop.
This guarantees either `.success` or `.fail` are send, as long as its
not leaked.
This seems to fix https://github.com/pop-os/cosmic-comp/issues/1305.
xdg-desktop-portal-cosmic prints an error, buy retries (as it should for
an `Unknown` error; though maybe there should be a retry limit) and the
session continues working.
(Not sure if it should be sending `failed`, or queing it with the next
frame so it can send `success` to the client, but this works and is
desirable as a failsafe anyway.)
`Session` and `CursorSession` are similiarly updated.
`.fail()`, `.success()`, and `.stop()` now consume
`Frame`/`Session`/`CursorSession`. So to stop a session, it is now
necessary to call `.remove_session()`, but then simply dropping with
send `.stop()`.
Factoring out some `Request::Capture` handling into a `capture_frame`
function seems to clean up error handling and such a bit.
If `redraw()` returned early, before updating `self.state`, but after
calling `queue_frame`, `on_vblank` would later be called, and reach
`unreachable` since state isn't set to `WaitinfForVBlank`.
In particular, this was happening when the dmabuf from the image copy
frame failed to `bind`.
To avoid this, make sure to update `self.state` immediately after
calling `queue_frame`, before any early return from an error.
The new type bounds seem to be addressable using `AsGlowRenderer`.
Though things like this will need a different solution when we want to
support Pixman rendering.
Adds support for cosmic-workspace-v2 pin, unpin, move_after, and
move_before requests.
Both features need some work with workspaces span displays mode, so that
will need more fixes later.
We also want to generate a unique id for pinned workspaces to send in
the ext-workspace-v1 protocol. But that isn't a strict requirement for
anything. So I haven't yet fully implemented that. We'll also want to
persist other things, like workspace naming when that's added.
Overall, though, with separate workspaces per display, this is working
pretty well.
This is slightly simpler, if there's not some reason I'm missing to do
this as it was previously done. And in particular provides a cleaner
API (if we wanted to move this to Smithay; perhaps without the Cosmic
extension).
But it also should be more correct. Presumably if a client (unusually)
had multiple components with their own `ext_workspace_manager_v1`
instance, they should have their own queues, and
`ext_workspace_manager_v1::commit` should be independent.
Inevitably, there's a racy element to multiple components trying to
update the workspace state like this, but it should behave the same as
two clients with separate connections.
(This is different from `CompositorClientState`, since the commit queue
there is fundamentally tied to the client, and different components with
their own compositor instance way have related surfaces.)
It seems at least with Rust 1.82 (the version in `rust-toolchain.toml`)
these bounds are inferred from the `D: WorkspaceHandler` bound, so they
can be specified only there.
Clients have been updated to use ext-workspace-v1 and
cosmic-workspace-v2.
Removing this should save some duplication of having to update both
cosmic workspace v1 and ext workspace code, and should help with things
like using the same workspace handle when a workspace moves to a
different group (which is something that was changed before the final
version of the ext-workspace-v1 protocol.)
