This is the filename convention you get when you define a shared module
in meson, and since there is no particular reason to not include the
"lib" prefix, lets make it easier to port it over. While at it,
de-duplicate the retrieval of the plugin name.
It'll be installed in the meta/ directory, so put the template files in
the corresponding directory in the tarball. This will also simplify the
port to meson.
While leaving the runtime checks in place, requiring xrandr 1.5 at build
time allows us to remove some seemingly unnecessary conditional
inclusion of functionality.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
testboxes was a binary that did unit testing, but it wasn't integrated
to the test system, so in effect, it was never run. Instead integrate it
into the other mutter unit tests. This includes changing a few of
meta_warning()s into g_warning()s so that the GTest framework can handle
them.
There are different unit-tests file generated containing lists of tests
the test-runner.sh should run. Running run-tests.sh read the unit-tests
in the current directory, which is inconvenient to do when using meson.
Closing a GdkDisplay during an event handler is not currently supported by Gdk
and it will result in a crash when doing e.g. 'mutter --replace'. Using an idle
function will close it safely in a subsequent main loop iteration.

meta_workspace_manager_override_workspace_layout is implemented by
calling meta_workspace_manager_update_workspace_layout which
respects the workspace_layout_overridden flag. After the first call
to meta_workspace_manager_override_workspace_layout all subsequent
calls fail silently.
Reset workspace_layout_overridden to FALSE before calling
meta_workspace_manager_update_workspace_layout.

drmModePageFlip() is guaranteed to fail for the invalid FB id 0.
Therefore it never makes sense to call this function with such argument.
Disabling a CRTC must be done with SetCrtc instead, for example.
Trying to flip to FB 0 not only fails, but it also causes Mutter to
never try page flip on this output again, using drmModeSetCrtc()
instead.
There was a race in setting next_fb_id when a secondary GPU was using
the CPU copy path. Losing this race caused the attempt to
drmModePageFlip () to FB ID 0 which is invalid and always fails. Failing
to flip causes Mutter to fall back to drmModeSetCrtc () permanently.
In meta_onscreen_native_swap_buffers_with_damage ():
- update_secondary_gpu_state_pre_swap_buffers ()
- copy_shared_framebuffer_cpu () but only on the CPU copy path
- secondary_gpu_state->gbm.next_fb_id is set
- wait_for_pending_flips ()
- Waits for any remaining page flip events and executes and destroys
the related page flip closures.
- on_crtc_flipped ()
- meta_onscreen_native_swap_drm_fb ()
- swap_secondary_drm_fb ()
- secondary_gpu_state->gbm.next_fb_id = 0;
- meta_onscreen_native_flip_crtcs ()
- meta_onscreen_native_flip_crtc ()
- meta_gpu_kms_flip_crtc () gets called with fb_id = 0
This race was observed lost when running 'mutter --wayland' on a machine
with two outputs on Intel and one output on DisplayLink USB dock, and
wiggling around a weston-terminal window between the Intel and
DisplayLink outputs. It took from a second to a minute to trigger. For
testing with DisplayLink outputs Mutter also needed a patch to take the
DisplayLink output into use, as it would have otherwise been ignored
being a platform device rather than a PCI device.
Fix this race by first waiting for pending flips and only then
proceeding with the swap operations. This should be safe, because the
pending flips could have completed already before entering
meta_onscreen_native_swap_buffers_with_damage ().
We might unset focus, or already be out of focus (e.g. an X11 client or
clutter text entry is focused) when a text-input state is committed by
the client. We handled this before, except when text input was
explicitly disabled by the client, the Wayland text-input was in focus
by the input method, and it focused itself out.
Simplify the logic a bit by just dropping the state on the floor in all
cases where after any potential focus changes were done, we are not
focused.
