Prior to this commit, WLR_RENDERER was only looked up when the
backend returned a DRM FD.
Make it so WLR_RENDERER is always looked up, so that running wlroots
on a system without a GPU and with WLR_RENDERER=gles2 fails as
expected instead of falling back to the Pixman renderer.

Switch from the pkg-config dependency names to the upstream
libxcb repository names. Each repository contains multiple
libraries but is generally available in distributions as a single
package.
libxcb contains xcb, xcb-composite, xcb-xfixes, xcb-xinput and
xcb-shm. libxcb-render-util contains xcb-render. libxcb-wm
contains xcb-icccm. xcb-image was outdated and is no longer needed.

We already get the PID from XRes and _NET_WM_PID code can overwrite it
with incorrect data.
|
|
`_NET_WM_PID` is unreliable: it is optional and even if set it may
contain PIDs from sandbox namespaces or remote systems.
Prefer XRes v1.2 QueryClientIds method which returns PIDs as seen by the
Xwayland server.

The NULL check already exists in wlr_texture_destroy, no need to
duplicate it in each impl

We were leaking wlr_pixman_buffers and a wlr_drm_format_set.

This fixes a crash when calling wlr_output_test() on a headless
output.

Make it clear GLES2 is being used. Before this commit, various
GL-related information was printed, but not an easy-to-find line
about which renderer is being picked up.
|
|
This env var forces the creation of a specific renderer. If no renderer
is specified, the function will try to create all of the renderers one
by one until one is created successfuly.

This examples uses `wlr_render_quad_with_matrix` to render coloured
squares on the screen, and uses the rotation to make them spin on their
middle.

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.

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.

If a NULL xkb_rule_names pointer is passed to
xkb_keymap_new_from_names, libxkbcommon will default to reading
the XKB_* env variables. So there's no need to do it ourselves.
Also s/xkb_map_new_from_names/xkb_keymap_new_from_names/ since the
latter is more consistent with the returned struct name.

Most of the examples had a GLES2 dependency, but weren't using it.
Convert multi-pointer to wlr_renderer instead of using directly
glClear.

This was lost in the session_impl removal refactor.

It allocates in local main memory via shm_open, and provides a FD
to allow sharing with other processes.
This is suitable for software rendering under the Wayland and X11
backends.

The function has been place in an internal header for API stability
reasons.

[1] has made wlroots unconditionally depend on libseat. Mention this

Create a private UNIX socket directory (755), or use an existing one but
ensure proper permissions are set to prevent meddling from other users.

The compositor shouldn't write to client buffers if the client
attaches a DMA-BUF to a wl_surface, then attaches a shm buffer.
Make gles2_texture_write_pixels return an error to prevent this
from happening.

libseat provides all session functionality, so there is no longer need
for a session backend abstraction. The libseat device ID, seat handle
and event loop handle are moved to the main wlr_session and wlr_device
structs.

This is instead delegated to libseat.

Since len <= strlen(elt) is known, we don't need a str*() function. Let's
simply do memcpy() to suppress linter false positive.
Fixes #2777.
|
|
This reverts commit 7dffe9339bf8a92a556098d86712c4c38ac95226, which introduced
another linter error with -O3:
error: ‘strncat’ specified bound 7 equals source length [-Werror=stringop-overflow=]
This makes sense because strncat(dest, "cursors", strlen("cursors")) is moot
in security point of view.
The next commit will replace strncpy() with memcpy(), so let's restore the
original implementation.
