Signed-off-by: Daniel Stone <daniels@collabora.com>
Instead of checking for each format whether we need compatibility
workarounds for GL implementations not supporting ES3.x or when
GL_EXT_texture_rg isn't present, have each format declare the ideal case
and fix it up later.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Rather than checking all the pixel-format components which are currently
duplicated inside gl-renderer, just check for equality of the pixel
format itself, which will become useful as we remove some of the
duplicate content.
This means that the texture storage will now be reallocated when clients
switch between pixel formats which could've had compatible GL storage
(e.g. XRGB <-> ARGB) on the same surface. However this does not seem
like a case worth optimising, and simplifies the code somewhat.

We do not migrate the weston_curtain destruction from
desktop_surface_removed() to desktop_shell_destroy_surface() because
we'd want have the curtain removed before the animation starts.
If we were to move the black view destruction, *and* only handle it from
desktop_shell_destroy_surface() the animation runs but the black curtain
will be removed right at the end, effectively diminishing the effect of
the animations.
To this end, we keep both of the two worlds, if the client terminates on
its own, we keep the same animation effect, but if the compositor is
shutting down we destroy it immediately.
We remove wl_list_for_each_safe() and instead loop each time to avoid
using a stale pointer iterator which could cause a UAF as the shsurf
would be free'ed.

... apart from SHM.
EGL and dmabuf buffers already have a gl_buffer_state created for them
when we first attach the weston_buffer. By turning
gl_surface_state::buffer into a pointer, we can just reference rather
than inline the gl_buffer_state.
SHM buffers are special, in that we don't keep individual copies of them
within the GL renderer. Instead, the GL surface has a texture allocated
with a shadow copy of the most up-to-date surface content. Handle this
by allocating and destroying gl_buffer_state every time we need to
respecify textures or somehow meaningfully change the parameters.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Similarly to EGL buffers, store the gl_buffer_state for a dmabuf buffer
inside weston_buffer, rather than on the linux_dmabuf_buffer. This
slightly simplifies our gl_buffer_state handling, and will be used later
to eliminate the egl_image refcounting.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Introduce a renderer_private hook for weston_buffer, and use this to
store a copy of the gl_buffer_state for EGL buffers (i.e. non-dmabuf, via
EGL_WL_bind_wayland_display).
As part of this, we create the EGLImage along with the weston_buffer
information, and just take a reference to it each time it is attached.
If you have bisected a failure to update surface content to this commit,
it very likely means that your EGL implementation requires images to be
recreated rather than only rebound in order to have their content
updated, which is contrary to specification.

At the moment, attach_shm() will modify the gl_buffer_state in place,
then compare it and see if it differs enough to require a new one. That
rather mixes up the old and new worlds, so quite explicitly build up a
shadow gl_buffer_state with variables first before we change the one
which already exists.

This patch re-introduces it to avoid leaking the view upon compositor
shutdown, but it does it in tandem with weston_desktop_surface_unlink_view(),
(which was added in a later patch) and before weston_surface_unref() call.
This way we should be safe to terminate/close clients with additional views
created by libweston-desktop (pop-ups), but also in other different situations.
Verified it in the following circumstances:
- terminating a client with close animation on
- terminating a client with close animations off
- shutting down the compositor with clients running, with and
without close animations
- terminating top-level clients with additional pop-ups with both with
and without close animations
