SDL has been building on GNU/Hurd for a long time, using either drivers
based on external libraries (e.g. X11, pulseaudio, sndio, etc) or dummy
drivers. This commit introduces it explicitly as platform, so it can be
recognized, and tweaked as needed. In particular:
- introduce the SDL_PLATFORM_HURD define
- tighten/improve the platform detection in cmake, and use "Hurd" as
identifier
- return the platform name in SDL_GetPlatform()
- tweak the CFLAGS/LDFLAGS so pthreads can be used properly
- implement SDL_GetExeName(), using /proc/self/exe as provided by the
basic Linux-like procfs
- enable GLES 2 in tests (mostly for consistency with Linux)
Use the existing SDL_GetExeName(), available for all the UNIX
platforms, in the internal GetAppName(); this has few advantanges:
- SDL_GetExeName() (and SDL_GetAppID() that builds on top of it) are
used in various places already; since it caches the executable name,
this may remove one extra read of the application name
- SDL_GetExeName() has a non-dummy implementation in more OSes than
GetAppName(), thus providing a small improvement for this IME
As drive-by change: since SDL_GetExeName() provides a constant string,
there is no more need to allocate a new string in GetAppName(), which
is used as constant string anyway. Hence, return a constant string in
GetAppName() too.
- Removed GTK signal handler in x11settings. XSettings events are now properly dispatched to X11_XsettingsNotify.
Previously events were not being passed to xsettings-client as no SDL xsettings_window was created. Now all events
are filtered through xsettings_client_process_event allowing it to process the external window events that are selected.
Global content scale is updated for changes to any recognized dpi settings.
- X11_GetGlobalContent now reads the current RESOURCE_MANAGER prop off of the root window to ensure it sees the
current value. XResourceManagerString is now only used if getting the current prop fails as it caches the current resource
manager value per-display connection.
- Clean up some warnings in SDL_gtk.
- gtk_init_check claims it will not terminate the program on failure, however this is does
not apply to the internal check it performs to see whether another GTK library is already
loaded, the detection of which triggers a g_error which glib treats as fatal.
- gtk_progress_get_type and gtk_misc_get_type are checked to match the checks done
by _gtk_module_has_mixed_deps.
- Clean up gtk/gdk loading. There are no library fallbacks so the one option available can
be loaded rather than iterating through a list of one item.
xpad has a series of questionable design choices when it comes to button
mapping. Notably, BTN_TRIGGER_HAPPY1-4 are used for the D-pad on dance mats
instead of the typical BTN_DPAD_*, and maps the paddles to
BTN_TRIGGER_HAPPY5-8. This commit plumbs through driver detection for a udev
device and adds special exceptions for xpad's quirks.
Newer kernels (6.17+) add the BTN_GRIP* mappings for paddles on controllers. We
should prefer that if available, as its meaning and mapping is unambiguous.
However, since it's only in new kernels, we need to maintain the older mappings
where we know they exist.
It also exposes KEY_RECORD as the share button regardless of vendor, which had
previously been gated behind being a Microsoft controller. All Xbox Series
controllers can include this button, and many third party ones do.
This specifically affects SDL_EnumerateDirectory and SDL_GetPathInfo. Android
assets are read-only, so no need to do this for things like
SDL_CreateDirectory, etc, and the POSIX SDL_CopyFile() uses SDL_IOStream
behind the scenes, which already supports Android assets.
Fixes#13050.
The surrounding code in all of these instances expects the Unicode
variants. Previously, this code mixed Unicode and ANSI/ASCII calls if
`UNICODE` was undefined, which caused type and logic errors. Explicitly
spelling out the W removes any reliance on that macro.
Wayland compositors may send recursive clipboard offers to the client, which need to be filtered out to avoid clearing local data. Previously this was worked around with a hack, but this caused the ownership flag to be set incorrectly, which broke some clients.
This introduces a metadata MIME type of application/x-sdl3-source-id to be sent with SDL3 selection offers, which contains a string that is a unique identifier for the instance, and can be used to detect if a received selection offer is originating from the same instance that generated it.
If DBus is available, the unique identifier string is the unique name of the connection, otherwise, the process ID is used.
This hint needs to persist outside of the normal application flow, so use the environment to set the initial value, and then save the value set via SDL_SetHint() after that.

This helps the Pipewire camera driver to access cameras
in a sandboxed environment without host Pipewire socket access.
Unlike other platforms, no event is sent when the user rejects
camera access. This is because there is no mechanism to query
cameras through the portal, and we only obtain access to the
Pipewire fd if the user accepts the request. The Pipewire driver
will attempt to open the host socket instead.
_GetWinID() doesn't work with keyboard-related BMessages, because Haiku
assumes you know what window has keyboard focus at the time, so these events
don't have a `window-id` property. So when this call failed, the key event
handler would return early.
This was probably a copy/paste error that snuck in at some point, as SDL2
doesn't have this issue.
The Wayland keyboard repeat code assumes that if we have a certain timeout then we'll wait at least that long, and generate a key repeat event on timeout. If we wait a shorter time, we won't generate a key repeat event and then return 0, even if we were supposed to wait indefinitely.
