Simon Ser 6622cd3277 output: correctly handle outputs without a test() impl
This fixes a crash when calling wlr_output_test() on a headless
output.

Simon Ser e8df7c367a linux-dmabuf-v1: split params and buffer
Previously, the same struct was used for linux-dmabuf-v1 params
and buffer. This made the whole logic a little bit awkward, because
a wlr_dmabuf_v1_buffer could either be still being constructed, or
be a complete buffer.

Introduce a separate wlr_linux_buffer_params_v1 struct for buffer
params still being constructed. Once the params are complete (ie.
once the create request is sent), the params struct is destroyed
and the buffer struct is created.

This will help with [1] as well.

Simon Ser f64ed60c7b linux-dmabuf-v1: drop some from_resource helpers
Drop wlr_dmabuf_v1_buffer_from_params_resource and
wlr_linux_dmabuf_v1_from_resource. Contrary to wl_buffer, these
resources are internal linux-dmabuf-v1 implementation details and
should not be shared with other interfaces.

Use 128-bit hexadecimal string tokens generated with /dev/urandom

build: remove xdg-foreign feature

With no external dependencies required, there's no reason not to always
build it. Remove WLR_HAS_XDG_FOREIGN as well.

Simon Ser d9cae04ffc linux-dmabuf-v1: always advertise support for implicit modifiers

from a protocol point of view.

The GLES2 renderer assumes it'll have a wlr_buffer to render to.

Instead of accomodating for the edge-case of rendering without a
wlr_buffer, drop wlr_renderer_blit_dmabuf calls and instead use
wlr_renderer_bind_buffer just like the rest of the wlr_renderer users.
wlr_renderer_blit_dmabuf is now unused in wlroots.

The upside is that the new blit_dmabuf function in screencopy is
renderer-agnostic.

Value is now an enum with a new value ("on-demand") that compositors can use to allow "normal" keyboard focus semantics regardless of the layer the client surface is on. An error is sent for invalid keyboard interactivity values. The old behavior is retained for clients using the previous version of the protocol.

Also adjusted the layer-shell example program to use the new keyboard interactivity options.

be reintroduced at a later date if a use-case is found.

Ilia Bozhinov 9595f95452 xdg_shell: handle inert popups
xdg_popups can be destroyed by the compositor when closed. When this happens,
wlroots makes the xdg_popup surface inert and resets the xdg_surface role to
NONE.

Currently, wlroots sends a protocol error and asserts that an xdg_surface has
a role when committed. This is racy if at the same time the client commits an
xdg_popup and the compositor closes it. This patch removes the assertion and
ignores commits on xdg_surfaces without a role set.

Simon Ser f0945e112f export-dmabuf: export DMA-BUF on output commit
We were previously exporting DMA-BUFs when receiving the capture_output
request, and sending a done event on wlr_output.events.precommit. Instead,
export and send done on wlr_output.events.commit.

screencopy: stop setting needs_frame flag
This is already done by wlr_output_schedule_frame (it calls
wlr_output_update_needs_frame).

Roman Gilg 86c0b9986b output-management-v1: send complete head state on enable change
The data of a head is only sent when it is enabled. While the head was disabled
data might have been changed. In this case clients were not informed about this
change. A later enable change that does not also update the other data must
still lead to the propagation of this data.

Since we do not know what other data was changed while the head was disabled
just send together with an enable change all current data.

Isaac Freund 8dec751a6d layer-shell: error on 0 dimension without anchors
The protocol requires clients to set opposing anchors when requesting
a width or height of 0.

The goal of this patch is not to break clients that rely on this
behavior but to improve the consistency of the layer shell ecosystem
through adherence to the protocol.

Isaac Freund 8ad2cc39eb layer-shell: add for_each_popup
This brings the layer-shell api in line with that of xdg-shell and
avoids reimplementing this function in every compositor in order to
render layer shell popups correctly.

Simon Ser b0144c7ded output-power-management-v1: listen to output commit 2020-08-27 13:54:19 -06:00
Simon Ser c674241ec0 output: introduce wlr_output_event_commit
This event contains a `committed` bitfield, which allows callers to know
which output fields changed during the commit.

This allows users to setup a single atomic commit listener, instead of
setting up one listener for each event (mode, scale, transform, and so
on).

Isaac Freund 2072d59da5 xdg-shell: split last-acked and current state
These states are distinct in the time period between the ack_configure
and the next commit on the surface. Splitting these states avoids the
following race for example:

- client starts at 1000x1000
- wlr_xdg_toplevel_set_size 500x500
- size is different -> configure sent
- client acks the configure
- wlr_xdg_toplevel_set_size 1000x1000
- compare_xdg_toplevel_state returns true since there is no pending
  configure and the currently committed size is still 1000x1000
- no new configure is sent
- client commits at the size it last acked, 500x500
