These report their VID/PID as a Nintendo Switch Pro controller, but they are actually left/right Joy-Cons. We'll fix up the joystick GUID so applications can handle them appropriately.
This reverts commit ff233fe306.
This doesn't compile cleanly with Visual Studio and I don't want to introduce any subtle issues because we're passing the wrong types of pointers to WGI functions.
This makes the joystick locking more robust by holding the lock while updating joysticks.
The lock should be held when calling any SDL joystick function on a different thread than the one calling SDL_PumpEvents() and SDL_JoystickUpdate().
It is now possible to hold the lock while reinitializing the joystick subsystem, however any open joysticks will become invalid and potentially cause crashes if used afterwards.

In order to inhibit the screen saver, SDL currently uses
`org.freedesktop.ScreenSaver.Inhibit()` and, as a fallback, a protocol
specific method for X11 or Wayland.
Accessing `org.freedesktop.ScreenSaver` is usually not allowed when
inside a sandbox like Flatpak, unless the permission has been explicitly
granted to the application.
Another issue is that the Wayland protocol "Idle inhibit" is relatively
new and not yet widely adopted. For example Mutter still doesn't support
it.
For those reasons, when running under Flatpak or Snap, we should try to
inhibit the screen saver by using xdg-desktop-portal instead. This
should give us an higher chance of success.

This is in the hope that revving the product version doesn't change the mapping, which is the case for some devices. In cases where it does, we just need to provide a mapping for each version of the product.
Adjust candidate count so list is not draw bigger that needed. This also fix potential uninitialised read of variable `candsize[i]` if `vertical` is false.
This is now used as a crc field in the mapping rather than directly in mapping guids, for better mapping compatibility between versions of SDL.
Added SDL_GetJoystickGUIDInfo() to get device information encoded in a joystick GUID, so that mapping programs can clear the CRC from the GUID when generating mappings.
sort_controllers.py has been updated to extract the CRC from mappings created by older mapping programs and convert it into the new crc field. It will also take the CRC into account when checking for duplicate mappings.
Also regenerated the GUIDs for the PS2/PSP/Vita controller mappings, fixing https://github.com/libsdl-org/SDL/issues/6151
This will make it possible to have mappings for different controllers
that have the same VID/PID. This happens frequently with some generic
controller boards that have been reused in many products.

Update the Wayland core protocol spec file and add support for the new axis_value120 event to handle high resolution scroll wheels.
The axis_value120 replaces the axis_discrete event, which is no longer sent as of version 8 of the protocol. Note that unlike the axis_discrete event, no mention in the spec is made regarding how many axis_value120 events may occur per-axis per-frame, so the values are accumulated and committed when the pointer frame event occurs.
The libdecor header internally includes wayland-client.h, which pulls in the wayland-client-protocol.h file from the system include path and overrides the local one generated from the included Wayland protocol spec files. Move the Wayland protocol header inclusion above the libdecor header inclusion to ensure that the locally generated protocol header is used instead.
When minimizing a window, we get this sequence of events:
WM_WINDOWPOSCHANGING
WM_GETMINMAXINFO
WM_NCCALCSIZE
WM_WINDOWPOSCHANGED - IsIconic() is true
WM_MOVE
WM_SIZE - SDL sees minimized state here
When restoring a window, we get this sequence of events:
WM_WINDOWPOSCHANGING
WM_GETMINMAXINFO
WM_NCCALCSIZE
WM_NCPAINT
WM_ERASEBKGND
WM_WINDOWPOSCHANGED - IsIconic() is false
WM_MOVE
WM_SIZE - SDL sees restored state here
On Windows 10 a minimized window has a non-empty client rect, so we were delivering a minimized size before SDL knows that the window is minimized, and then ignoring the restored size when handling the restore message.
The fix is to use IsIconic() which returns the correct window state when WM_WINDOWPOSCHANGED is actually delivered.
Uses VK_EXT_metal_surface (vkCreateMetalSurfaceEXT)
when possible, otherwise falls back to the obsoleted
VK_MVK_macos_surface and VK_MVK_ios_surface.
Fixes#3906
If libdecor performs a commit with the frame title being undefined, a crash can occur within the library or its plugins. Always ensure that the title is set to a valid string to avoid this.
This prevents crashes when calling SDL joystick API functions from a different thread while disconnection is happening.
See https://github.com/libsdl-org/SDL/issues/6063 for a more thorough review of joystick locking.
Eliminate excessive calls to SetFullscreen by removing the calls in the libdecor and xdg-toplevel config callbacks.
These calls were being made there in case something explicitly called the window minimization function from within SDL, which unsets fullscreen, and as minimizing a window in Wayland is just a suggestion to the compositor and doesn't actually change the window state or communicate anything back to the application, it was necessary to call SetFullscreen in every call to the config functions just in case something minimized a window via SDL_MinimizeWindow() and later needed to restore it. GNOME in particular had issues when fullscreen set/unset operations were being hammered, leading to overlapping acks and commits when switching to fullscreen.
With the new video system flag to disable unsetting fullscreen when minimizing a window, these calls in the configuration functions are no longer needed and can be removed. This significantly reduces calls to the SetFullscreen() function, reverts #6044 while fixing the issue, and fixes a similar problem when hiding and showing a window initially created with fullscreen flags.
Add quirk flags to the video device struct and add flags to allow video backend drivers to disable mode switching and disable unsetting the fullscreen mode when minimizing a window. As certain platforms can have multiple video backends compiled in at once, #ifdefs, as used by other platforms, aren't suitable as different backends on the same platform may not need the same quirks.
This replaces the formerly dedicated 'disable_display_mode_switching' boolean as additional quirks are needed by the Wayland backend. Helper functions have also been added to simplify reading the flag states.
If the D-Bus subsystem is shutdown and restarted mid-execution, the cached connection will be invalid. Fetch it each time that it is used to ensure that the connection is always from the current context.
Don't call the roundtrip in ShowWindow unless restoring a previously hidden window. This fixes a regression in GNOME when creating a window with the fullscreen flag set, as the fullscreen window will be positioned down the screen by the height of the top bar if the window is made fullscreen on the primary display and the roundtrip is called when initially displaying the window.
SDL_CreateWindow() may call GetWindowDisplayIndex() to compute the position
of a new window that the caller has requested to be placed on a certain
display. Since we haven't fully constructed the window yet, our driverdata
will be nil and we will fail to get the NSScreen (which is fine). However,
we need to return an error (not 0, which is a valid display index) for
SDL_GetWindowDisplayIndex() to know to figure out the display index itself.
Fixes positioning new windows on secondary displays when using
SDL_WINDOWPOS_CENTERED_DISPLAY() and SDL_WINDOWPOS_UNDEFINED_DISPLAY().
OpenGL windows don't actually get the WM_WINDOWPOSCHANGED event in the SetWindowPos() call in WIN_SetWindowFullscreen(), so setting the window size to zero never gets reset and we're stuck with a zero sized window.
Instead, just force the resize event in WM_DPICHANGED handling, where we know we need it. If we end up needing to force it in WIN_SetWindowFullscreen(), just set a flag in the window data and respond to that in WM_WINDOWPOSCHANGED, but that's a fairly risky behavior change as suddenly all applications would start getting SDL_WINDOWEVENT_SIZE_CHANGED when going fullscreen, and they may respond to that in expensive and potentially disruptive ways.
For later we'll probably create a DPI changed event and respond to that in the renderer instead of this window size changed hack.
This fixes https://github.com/libsdl-org/SDL/issues/6033 @ericwa
The video core assumes that window->w/h will be updated before returning
from SetWindowFullscreen(). This is needed to generate a resize event
with the correct window size when exiting fullscreen.
The roundtrip allows us to receive the configure callback that informs
us of the new window size before returning.
Fixes#6043
We really only care about DPI changes here, so this both reduces work and also avoids weird cases where viewport state can be corrupted by trivial window events. This doesn't _completely_ get rid of the issue but this is somewhat intentional, since apps will definitely want to do a full reset when changing displays anyhow (otherwise DPI/adapter changes will screw things up, and that's out of our control as long as both window size and drawable size are exposed at the same time.
Note that OpenGL still captures window events because of weird platform-specific issues like macOS and viewport stretching!
Fixes#5949
- This allows looking up the display index for an arbitrary location rather than requiring an active window to do so.
- This change also reimplements the fallback display lookup that found the display with center closest to the window's center to instead find the display rect edge
closest to the window center (this was done in the almost identical display lookup used in SDL_windowsmodes.c, which now uses `SDL_GetPointDisplayIndex`). In
practice this should almost never be hit as it requires the window's center to not be enclosed by any display rect.
The current method of toggling the libdecor window visibility by destroying and recreating the frame results in a race where a use-after-free bug can manifest itself within libdecor when window visibility is toggled quickly. Instead, use the libdecor function for toggling visibility instead of destroying and recreating the frame every time.
Wayland works like SDL's "auto capture" feature already, tracking the mouse
globally only while a drag is occuring, and this is the only way to get mouse
input outside the window.
Setting this flag ourselves lets SDL_CaptureMouse() work in the most common
use case without actually implementing CaptureMouse for the backend, including
SDL's auto capture feature.
Fixes#6010.
This controller actually comes in at least two flavors: a GameCube controller and an arcade pad, neither of which should have the face buttons remapped.
This controller looks like a GameCube controller, is actually a Nintendo Switch controller, and shows up as an XInput device on Windows with the buttons already in the correct location.
The Nintendo Online Sega Genesis controller reports the SNES VID/PID over Bluetooth. This is a more robust way of handling future controllers as well, so let's go with this instead.
Also use full reports over Bluetooth, and don't report gyro for Nintendo Online classic controllers.
GNOME exposes the cursor size and theme via the org.freedesktop.portal.Settings interface of the xdg-desktop portal, so query these values via D-Bus, if available.
The XCURSOR_SIZE/XCURSOR_THEME envvars will be tried first, so as not to override any user specified sizes or themes, then D-Bus, then, failing that, it will fall back to default values.
The event no longer spams each time a window gets focus if there are windows on monitors with different color profiles.
This also has the side effect that you no longer get a color profile event at window creation, which is consistent with other events that communicate state changes.
Previously, calling SDL_SendWindowEvent for a SIZED_CHANGED event would
filter the queue to remove RESIZED and SIZED_CHANGED events, so you don't
overflow the queue with obsolete data, but any RESIZED events would be
lost in this process.
Now we note if there was a RESIZED pending and replace it with a new
event using the same dimensions as the new SIZED_CHANGED event. This fixes
cases where an app is only listening for RESIZED events and thus might
lose important information in some cases.
Fixes#5925.
This is necessary for consistent position reports with absolute mice
and improves application performance with relative mice by cutting the
number of reported mouse motion events roughly in half.
Use the xdg-desktop-portal interface to RealtimeKit1, when available, to set realtime scheduling and elevated priority for threads. This portal allows for the use of rtkit within containers such as Flatpak. It will fall back to using RealtimeKit1 directly if the xdg-desktop-portal interface is too old or not available.

SDL_events_need_periodic_poll() and SDL_events_need_polling() are intended to allow the event loop to update joysticks and/or sensors if needed, however those systems only update when the SDL_update_joysticks and/or SDL_update_sensors variables are true. This change brings the behavior of these functions in line with if work will actually need to be performed.
This change allows the hints for AUTO_UPDATE to influence the polling behavior of the event loop such that an app can choose to update joysticks/sensors itself and avoid the expense of constantly sleeping and waking the event loop. Additionally in makes these functions marginally faster in some situations by not searching the active events.
Hint callbacks are called before the actual value in the hint is changed, so the functions SDL_AutoUpdateJoysticksChanged and SDL_AutoUpdateSensorsChanged were not actually properly updating their respective variables in repsonse to their auto update hint changing.
Instead, we pull the new hint value out of the value passed into the callback and use that to update the variables. Assume true on a null value as that was the previous behavior and it matches with the default values of SDL_update_joysticks/SDL_update_sensors.
Events to handle controller touchpads and sensors were added to the library but not added in `SDL_GameControllerEventState()`. This change adds the missing events.
- CMD_CHARGE_STATE was checking the seqnum instead of the payload
- Off-by-one error in size validation for command payload
- Unused payload space was left uninitialized in output report
As discussed in PR review, there may be an off-chance that the index
returned doesn't match up with SDL's display indexing.
This change ensures that the indices match and adds a safety check for
off-screen windows.
With the introduction of this function, it is possible that for certain
monitor and window configurations, creating an SDL window will cause a
native crash.

In testing, the window would not find a valid screen if created
"hanging" off a primary display with a secondary display below it. In
checking why this was the case, the `display_centre` was being
calculated with a negative y origin, causing a final negative value
falling outside all display bounds:
```
SDL error log [debug]: display_centre.y = -1296 + 1296 / 2
SDL error log [debug]: Display rect 0: 0 0 2560 1440
SDL error log [debug]: Display rect 1: 2560 -625 1080 2560
SDL error log [debug]: Display rect 2: 0 1440 1728 1296
```
The method that was being used to find the current window using the frame
origin/size seems unreliable, so I have opted to replace it with with a
tried method (https://stackoverflow.com/a/40891902).
Initial testing shows that this works with non-standard DPI screens, but
further testing would be appreciated (cc @sezero / @misl6 from the
original PR thread).
We actually request CSD mode with xdg-decoration for borderless
windows, so we get what we wanted there and there's no point in going
into fallback paths.
The 5.1 versions didn't use the new algorithm, and making that new
algorithm work took so many permutes that it was significantly slower
than just using the scalar versions.
However, mono-to-stereo is an extremely common conversion, and it's
trivial to accelerate it with plain SSE, so that was added!
Currently, the SDL_WINDOWEVENT_RESIZED event is sent before the actual
window is resized (and various internal state, such as the desired
GL/Vulkan backbuffer size, are updated). This makes sense, as SDL will
discard a no-op resize, which would be the case if we had resized before
sending the event (indeed, there are existing hacks to prevent this).
However, this means that SDL_{GL,Vulkan}_GetDrawableSize() will still
use the old size in the SDL_WINDOWEVENT_RESIZED handler. In the case of
SDL_Renderer, this means the drawable size it uses will be wrong, and
the viewport will get "updated" to the old value.
This then results in bug #5899.
Pipewire 0.3.44 introduced PW_KEY_TARGET_OBJECT, which is to be used to specify target connection nodes for streams. This parameter takes either a node path (PW_KEY_NODE_NAME) or serial number (PW_KEY_OBJECT_SERIAL) to specify a target node. The former is used in this case since the path is already being retrieved and stored for other purposes.
The target_id parameter in pw_stream_connect() is now deprecated and should always be PW_ID_ANY when PW_KEY_TARGET_OBJECT is used.
Make the default device metadata node persist for the lifetime of the hotplug loop so the default source/sink devices will be updated if they change during runtime.
With Pipewire now requiring a minimum version 0.3.24, the PW_KEY_CONTEXT_PROFILE_MODULES value is no longer required for legacy compatability and can be safely removed.
* Fix assumption that DRI_DEVNAME begins at 0
The existing logic of the code was to count every possible entry in
KMSDRM_DRI_PATH. After this a for loop would start trying to open
filename0, filename1, filename2, etc. In recent Linux kernels (say
5.18) with simpledrm, the lowest KMSDRM_DRI_DEVNAME is often
/dev/dri/card1, rather than /dev/dri/card0, causing the code to fail
once /dev/dri/card0 has failed to open. Running:
modprobe foodrm && modprobe bardrm && rmmod foodrm
before you try to run an application with SDL KMSDRM would have also
made this fail.

When building on macOS without gcc (e.g. clang) where HAVE_GCC_ATOMICS
is not defined, `SDL_AtomicTryLock` will call
`OSAtomicCompareAndSwap32Barrier` which is not yet declared.
Including OSAtomic.h on OSX resolves this error/warning:

'OSAtomicCompareAndSwap32Barrier' is invalid in
C99 [-Werror,-Wimplicit-function-declaration]
return OSAtomicCompareAndSwap32Barrier(0, 1, lock);
This was reported in issue #3885 but marked Invalid and closed - possibly
because the default CMake build uses gcc instead of clang.
The documentation doesn't state that the argument is ever modified,
and no implementation does so currently.
This is a non-breaking change to guarantee as much to callers.
strchr and strrchr return a pointer to the first/last occurrence of a
character in a string, or NULL if the character is not found. According
to the C standard, the final null terminator is part of the string, and
it should thus be possible to get a pointer to the final null with
these functions. The fallback implementations of SDL_strchr and
SDL_strrchr would always return NULL if trying to find '\0', and this
commit fixes that.

Some compositors will provide 'nicer' / 'human readable' output descriptions via the xdg-output protocol. Use these description strings, when available, instead of the model name provided by wl-output. On compositors such as GNOME where this is provided, the display names provided to applications by SDL will now match those in the desktop display settings panel. On compositors where this data isn't provided, the old behavior of using the model string provided by wl-output will remain unchanged.
Additionally, per the protocol spec, output data provided by xdg-output should supersede wl-output data, so this is the recommended behavior in general.
If the width is sufficiently ludicrous, then the calculated pitch or
the image size could conceivably be a signed integer overflow, which
is undefined behaviour. Calculate in the unsigned size_t domain, with

Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to
change the SDL coordinate system units to be DPI-scaled points, rather
than pixels everywhere.
This means windows will be appropriately sized, even when created on
high-DPI displays with scaling.
e.g. requesting a 640x480 window from SDL, on a display with 125%
scaling in Windows display settings, will create a window with an
800x600 client area (in pixels).
Setting this to "1" implicitly requests process DPI awareness
(setting SDL_WINDOWS_DPI_AWARENESS is unnecessary),
and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.
If the move results in a DPI change, we need to allow the window to resize (e.g. AdjustWindowRectExForDpi frame sizes are different).
- WM_DPICHANGED: Don't assume WM_GETDPISCALEDSIZE is always called for PMv2 awareness - it's only called during interactive dragging.
- WIN_AdjustWindowRectWithStyle: always calculate final window size including frame based on the destination rect,
not based on the current window DPI.
- Update wmmsg.h to include WM_GETDPISCALEDSIZE (for WMMSG_DEBUG)
- WIN_AdjustWindowRectWithStyle: add optional logging
- WM_GETMINMAXINFO: add optional HIGHDPI_DEBUG logging
- WM_DPICHANGED: fix potentially clobbering data->expected_resize
Together these changes fix the following scenario:
- launch testwm2 with the SDL_WINDOWS_DPI_AWARENESS=permonitorv2 environment variable
- Windows 10 21H2 (OS Build 19044.1706)
- Left (primary) monitor: 3840x2160, 125% scaling
- Right (secondary) monitor: 2560x1440, 100% scaling
- Alt+Enter, Alt+Enter (to enter + leave desktop fullscreen), Alt+Right (to move window to right monitor). Ensure the window client area stays 640x480. Drag the window back to the 125% monitor, ensure client area stays 640x480.
The hint allows setting a specific DPI awareness ("unaware", "system", "permonitor", "permonitorv2").
This is the first part of High-DPI support on Windows ( https://github.com/libsdl-org/SDL/issues/2119 ).
It doesn't implement a virtualized SDL coordinate system, which will be
addressed in a later commit. (This hint could be useful for SDL apps
that want 1 SDL unit = 1 pixel, though.)
Detecting and behaving correctly under per-monitor V2
(calling AdjustWindowRectExForDpi where needed) should fix the
following issues:

I was looking at how errors are handled by SDL and came across this #define SDL_ERRBUFIZE which looks like a typo for SDL_ERRBUFSIZE, but either way, it looks like this isn't being used anywhere anymore because it was getting reported whenever I compile SDL with -Wunused-macros, and the last time it was mentioned in the code was from commit 09ca66b.
XDG-toplevel min/max size values are double-buffered data and must be committed before entering the fullscreen state, or a max window size value smaller than the display dimensions may cause the compositor to incorrectly configure the fullscreen window size. This fixes windowed->fullscreen transitions on GNOME, where, previously, certain combinations of window flags and min/max size values could cause entering fullscreen mode to fail with odd window sizes and/or offsets due to the new max size values not being committed before entering fullscreen, causing the compositor to clamp to the old values.
In the case of libdecor, it has its own layer of buffering on top of the xdg-toplevel surface for the min/max window dimensions, so both a frame commit and surface commit are required to set the state properly.
Previously, the surface damage region was being set in the same callback used for preventing render hangs in the GL backend when the surface was not visible. This was not ideal, as the callback was never fired in the case of using a different render backend or having a swap interval of 0. Use a separate frame callback for setting the surface damage region to ensure that it fires reliably, regardless of the backend being used or swap interval.
Some compositors (GNOME for example) don't set the transform flag when dealing with portrait mode displays, so the video modes won't have the width/height swapped in all cases where they should be. Check for both the 90/270 degree transform flag and if the display is taller than it is wide when determining whether to swap the width and height of the emulated video modes, and adjust the comparison logic when size testing against the native mode to account for this.
Add the hint "SDL_VIDEO_WAYLAND_MODE_EMULATION", which can be used to disable mode emulation under Wayland. When disabled, only the desktop and/or native display resolution is exposed.
Previously, scale values used by the displays and surfaces were always integers, with fractional scale values only being calculated when the backbuffer and viewport sizes were being determined. Now, if xdg-output is available, the fractional scale of output displays is calculated when the displays are enumerated and the true scale values of the output devices are used whenever possible.
This unifies the integer and fractional scaling systems, allows for the use of more accurate scale values that minimize overdraw when windows straddle multiple outputs, and lays the groundwork for the pending Wayland scaling protocols that will report the preferred scale values per-surface instead of per-output.
Compartmentalize the fullscreen mode emulation code blocks, unify the windowed/fullscreen viewport logic, consolidate all window geometry code into a central function to eliminate blocks of duplicate code and rename related variables and functions to more explicitly reflect their purpose.
Because we were sending multiple chunks of preedit strings,
`SDL_SendEditingText` was using the old `SDL_TEXTEDITING` event only.
Now if `SDL_HINT_IME_SUPPORT_EXTENDED_TEXT` is enabled, we send the full
string and correctly set the cursor position and selection size.
