Libdecor has some quirks and depending on the setup it might be useful
to switch to the xdg-shell branch. Recompiling the whole engine without
libdecor is not an acceptable way to do that.
Makes it more consistent with the rest of the `WaylandThread` methods
(so that we can silently check for the window's existence).
Fixes errors when trying to capture the pointer when no surface has been
pointed yet (its logic assumed that this method was silent).
We double-check everywhere anyway but I added it in some places where we
can't either guarantee that it'll check (to avoid segfaults) or that
would be useful to report directly.
scale_changed and size_changed were incorrectly initialized to true,
causing redundant WindowRectMessage and DPI change events to be pushed
on every configure event regardless of actual changes.
Previously we had different logic for direct key presses and client-side
key repetition, as one queued up input events and the other dispatched
them directly (client-side key repetition is run from the main thread).
I kinda figured out that this difference doesn't really matter, as we
can queue them up before the thread message dispatching logic. That's
exactly what we do now, which allows us to make a single method for both
of them, making the code much clearer and simplifying future maintenance.
This patch also includes a tiny fixup in the compose logic, which checks
for the validity of the generated key event before actually working with
it. The cases in which we can end up with an invalid reference are very
few, so it's not the end of the world, but it's still absolutely a good
idea to check, to avoid nasty surprises down the line.
The `wl_keyboard::repeat_info` event got introduced in version 4. On
versions older than that, we defaulted to 0 delay, which means no
repetition. That's a veeery old version and basically everything offers
it, but it doesn't hurt to add a reasonable default.
`send_wayland_message` takes in the number of words, not its byte size.
This meant that we were sending quite a bit of out-of-bounds stuff
alongside the four arguments required by
`xdg_positioner::set_anchor_rect`, which triggered an assertion on Jay.
This didn't pop up before because the C wayland server library does not
seem to check this, but it's a valid (and useful!) assertion
for other server implementations nonetheless.
This patch switches to the initializer_list syntax to make the intent
clearer.
This patch introduces a new protocol proxy, which multiplxes Wayland
clients into a single connection, allowing us to redirect calls (e.g.
create toplevel -> create subsurface). Mixed with some state tracking
and emulation, we can embed a full-featured client into the editor.
Previously, on Linux and BSD, inhibiting the screensaver was handled
using the org.freedesktop.ScreenSaver D-Bus API. Unfortunately, this API
is not available in a Flatpak sandbox. (This is because there is a
desire to tie inhibit sessions to a specific app and visible window; but
the org.freedesktop.ScreenSaver API does not support this.)
As a result, when using the Flatpak build of the Godot Editor (or a
Flatpak-ed build of a game) and using a controller to play a game, the
session will become idle after a few minutes.
The XDG desktop portal -- which is already used for color-picking, file
choosing, and querying the system theme -- has an Inhibit interface that
provides a superset of the functionality of the
org.freedesktop.ScreenSaver API, and is available to any sandboxed app.
Refactor code for making XDG portal requests that was previously
duplicated for the FileChooser and ColorPicker portal code. Check the
portal version to determine whether these portals can be used:
- FileChooser portal version 3 is required due to the use of the
"directory" parameter.
- On the Settings portal, the only addition in version 2 is the
ReadOne() method which is not used here, so version 1 suffices.
- On the Screenshot portal, the only addition in version 2 is the
"interactive" parameter to the Screenshot() method; this code only
uses the PickColor() method, so version 1 suffices.
Then, add support for the Inhibit portal. Use it if available and if
running in a sandbox. Prefer to use org.freedesktop.ScreenSaver if not
running in a sandbox, even if the portal is available, because (at least
in the GNOME 43 implementation of the portal) it does not work correctly
if the portal cannot map the request to a running app. This adds a small
amount of complexity to the implementation, but supporting both APIs is
necessary anyway (there are many systems in the wild that support
org.freedesktop.ScreenSaver but not the desktop portal).

Fixes a timing issue where dialogs got configured right before having
their parent set. This gave compositors the time to resize/rearrange the
dialog as if it were a normal window, only to be marked as "floating"
right away. On niri, this manifested as huge dialog windows.
This is achieved with the addition of a `p_parent_id` parameter to
`window_create`, akin to its popup counterpart.
`window_create` now also accepts a single `Size2i` parameter instead of
two integers, in line with the rest of the `WaylandThread` API. The
original idea was to have a very "barebones" API, akin to the `drivers/`
directory, but that didn't pan out.
This race condition made me pull my hair. `wl_display_roundtrip` has its
own little event loop, which apparently conflicts hard with the
always-running event loop thread.
I kinda assumed that it would be thread-safe thanks to its internal
`wl_display_prepare_read` call that the docs talk about but that's
clearly not enough.
Luckily this method is called very few times and the only dangerous
instances are in the initialization routine, which first starts the
thread and then does various roundtrips. Libdecor has also some internal
roundtrips of its own which would often fail. Starting the thread after
all initialization fixes the issue.
Tested this by spamming *lots* of `wl_display_roundtrip` in
`WaylandThread::init()` with and without this fix.
Without this, the screen does go into idle after a few minutes on a RPi5 with default install (wayland w/ labwc), even
though `screen_keep_on` is set. DBUS is enabled but apparently, the screensaver call is not enough.
