I have an annoying issue on MacOS about XBoxOne Bluetooth rumble (Vendor: 0x045e, Product: 0x02fd).
When 360controller is installed, rumble is working correctly. However, Bluetooth rumble isn't working at all, with or without 360controller installed (although it is working with Chrome + https://html5gamepad.com).
I looked at the code, and it seems that XBox controllers are managed in MacOS in this file: SDL_hidapi_xbox360.c. The XBoxOne file is disabled for MacOS in SDL_hidjoystick_c.h.
The function HIDAPI_DriverXbox360_Rumble() is called correctly, and hid_write() returns no error.
I have tried a stupid test. I took the rumble packet from 360controller: ec4e88eb2d/XBOBTFF/FFDriver.cpp (L620). With the patch I have attached, I manage to have rumble working on Bluetooth (with some stupid vibration level, but it proves it can if the packet is changed).
But it breaks the USB rumble with 360controller. A comment in the function makes an explicit reference to 360controller, I think that's why I have broken this specific usecase.
I don't know what is the correct way to fix this, but it seems that the current implementation has a missing case for Bluetooth support.
Note that I also tested master this morning, and I have another issue:
if (!device->ffservice) {
return SDL_Unsupported();
}
test fails in DARWIN_JoystickRumble(). This test has been done quickly, I'm not totaly confident about its accuracy.

creating a fullscreen window with SDL_CreateWindow(..SDL_WINDOW_FULLSCREEN_DESKTOP..) in MacOS works fine, except if it was triggered by the user with the green knob in the top left window title bar.
Then "something" is different, and SDL_CreateWindow hangs for 15-20 seconds (tested in MacOS 10.13 and 10.14).
Responsible for the hang is this code in SDL_cocoawindow.m - Cocoa_SetWindowFullscreenSpace:
const int maxattempts = 3;
int attempt = 0;
while (++attempt <= maxattempts) {
/* Wait for the transition to complete, so application changes
take effect properly (e.g. setting the window size, etc.)
*/
const int limit = 10000;
int count = 0;
while ([data->listener isInFullscreenSpaceTransition]) {
if ( ++count == limit ) {
/* Uh oh, transition isn't completing. Should we assert? */
break;
}
SDL_Delay(1);
SDL_PumpEvents();
}
if ([data->listener isInFullscreenSpace] == (state ? YES : NO))
break;
/* Try again, the last attempt was interrupted by user gestures */
if (![data->listener setFullscreenSpace:(state ? YES : NO)])
break; /* ??? */
}
One trivial workaround is to change 'const int limit = 10000' to 500. Then the freeze is so short that it doesn't look like a freeze to the user.
Looking further into the problem, I observed that the function Cocoa_SetWindowFullscreenSpace recursively calls itself via some ObjectiveC messages. I managed to extract a callstack for this (copied below): Note how Cocoa_SetWindowFullscreenSpace in stack line 22 calls SDL_PumpEvents, which eventually arrives at SDL_SendWindowEvent, which calls SDL_UpdateFullscreenMode (stack line 0), which then calls Cocoa_SetWindowFullscreenSpace again (not shown). This recursive second call is the one that hangs.
Another "solution" that worked for me was to add a flag to SDL_Window that is set in Cocoa_SetWindowFullscreenSpace and causes this function to return immediately if called from itself.
Obviously, this is also an ugly hack, but I don't have enough time to dive into this crazy Cocoa/ObjectiveC business deep enough to find a proper solution. But hopefully it's easy for one of the experts around.
Note that there is a "failure to go fullscreen"-message involved, maybe using the green knob causes this failure at first.
I can unfortunately not provide a minimum example.
Best regards,
Elmar

Attached is a diff that I used to get SetThreadPriority working locally. I still have no idea what the minimum SDK version is since Microsoft never documented it, but it's worth pointing out that they're much more aggressive about using the latest VS and UWP SDK anyway (for example, an updated Xbox is no longer compatible with VS2017, and updates are required to have a network connection of any kind).

At the moment i get following warnings from kmsdrm:
* in SDL_kmsdrmvideo.c KMSDRM_DestroySurfaces is return type int, but thats never returned or checked against
* in SDL_kmsdrmvideo.c KMSDRM_DestroySurfaces the variable viddata is not used
* in SDL_kmsdrmopengles.c KMSDRM_GLES_LoadLibrary a cast to NativeDisplayType is missing
I attached a patch for them :)
- Regression of test_1.c of bug 3827, after fix from bug 4798.
- Blending is also needed when the palette contains alpha value, but not necessarily colorkey.
- Clean up SDL_ConvertColorkeyToAlpha which doesn't seem to need 'ignore_alpha' parameter any-more.
(see bug 3827)
A good metric of this is when the titlebar's "minimize" button is reenabled,
which doesn't happen by the time windowDidExitFullscreen triggers.
This fixes minimizing a fullscreen window on macOS.
Fixes Bugzilla #4177.
This is the OpenGL line drawing fix for Bugzilla #3182, but there's some
disagreement about what the renderers should do here, so I'm backing this out
until after 2.0.12 ships, and then we'll reevaluate all the renderer backends
to decide what's correct, and make them all work the same.

Since https://hg.libsdl.org/SDL/rev/f908bd722523 / bug 4966 i cannot build SDL anymore. The error i get is, essentially, caused by -Werror=declaration-after-statement in SDL_kmsdrmvideo.c and SDL_kmsdrmopengles.c
Wait up to 100 milliseconds, since the window manager might alter or
outright veto the window change...or not respond at all.
In a well-functioning system, though, this should help make sure
that SDL_SetWindowPosition's results match reality.
Fixes Bugzilla #4646.
OpenGL apparently needs to not do any drawing between wl_egl_window_resize
and eglSwapBuffers, but Vulkan apps don't use SDL to present, so they
never call into an equivalent of SDL_GL_SwapWindow where our Wayland code
was handling pending resize work.
Fixes Bugzilla #4722.
This is obnoxious and wrong, but the patch that activates the Dock before
activating the app fixes the _menu_ not responding on Catalina, but the
first window created by the app won't have keyboard focus without a small
delay inserted.
This obviously needs a better solution, but it gets it limping along correctly
for now.

We did some investigations into a different direction which I would like to share. As mentioned previously the scaling setting in the preferences play an important role for our problem and they also hint towards an issue with point/pixel scaling factors.
We found an interesting correlation between our fail case and the behavior of [nsWindow.screen backingScaleFactor]. It turns out that whenever we encounter the fail case the scale factor is zero when we print it quickly after calling SDL_CreateWindow. After some time the value changes to a non-zero value. In the success case the scaling factor is nonzero 'immediately'. Note that we don't use that factor. We also find that the window backingScaleFactor does not show the strange behavior even in the fail case.
We have also attempted to find out whether any event triggers the transition from zero to non-zero. We found the transition happening when we call SDL_PollEvent. We can even force this to happen by explicitly adding a SDL_PollEvent at an early stage, but it will only happen if a certain amount of time elapsed, so we need to add some sleep before the call to trigger the transition at an earlier stage. All that seems to imply that the transition happens async and that SDL_PollEvent merely causes the system to update its internal state at that time.
We have also verified that the scaling setting in the preferences does NOT directly correlate to the scaling factor behavior. We find that a particular scaling setting can lead to a fail case for one resolution and a success case for another resolution. This shows that the scaling setting alone does not determine whether the problem will appear or not.
We have also verified on another Mac with 10.14 that the scaling factor is always non-zero and we always have the success case.
I have no idea how to interpret this initial-zero behavior and haven't found any usable information on the screen backing scale factor. It seems as 10.15 does some stuff more async than before and maybe the problem could be caused by unfortunate timings. I would be very interested to hear your opinion about that.
...
Finally we found the cause of all our problems: it's the origin hack in Cocoa_SetWindowFullscreen:
/* Hack to fix origin on Mac OS X 10.4 */
NSRect screenRect = [[nswindow screen] frame];
if (screenRect.size.height >= 1.0f) {
rect.origin.y += (screenRect.size.height - rect.size.height);
}
If we comment this one out our game and testdraw2 do behave correctly.
It turns out that if a window is not fully contained in the screen, it's screen property becomes zero and therefore we saw a zero when printing the backing scale factor (although it's not clear why it became nonzero later).
We suggest to add a runtime check which skips this code for 10.15 (or possibly earlier if you happen to know that the hack is not needed for certain older versions).
More info: consider the line
NSRect screenRect = [[nswindow screen] frame];
in Cocoa_SetWindowFullscreen. We found that this rect has the dimensions of the desktop
on our OS X 10.15 setup. This is true both for the success case and the fail case. It seems as the success case is actually a fail case in disguise.
On the other Mac with OS X 10.14 the same rect has the dimension of the newly created screen. This is what I would expect, because at that time the window has already been created successfully and there should be a newly created screen associated to the window.
What are the cases in which the whole origin conversion code for the fullscreen case is supposed to have a non-trivial result?
Today we found that if we print the dimensions of [nswindow screen] later, then we find them to be correct. So the conclusion seems to be that OS X 10.15 does indeed do the window/screen setup more async than before and that the origin correction code uses the [nswindow screen] at a time where the window/screen setup isn't finalized yet.
It was done to allow hotkey resizing of borderless windows, but Windows will sometimes draw it, regardless of our WM_* message handling. See bug 4466 for more details.

When using Win10 on-screen keyboard (tooltip.exe), the left and right cursor keys in it do not produce SDLK_LEFT and SDLK_RIGHT events.
Windows messages generated by the on-screen keyboard, for some reason, have their scancodes set to zeroes. Here is the log from Spy++:
WM_KEYDOWN nVirtKey:VK_LEFT cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
WM_KEYUP nVirtKey:VK_LEFT cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:1 fUp:1
Regular physical keyboard produces VK_LEFT (ScanCode:4B) and VK_RIGHT (ScanCode:4D) which are interpreted correctly.
With on-screen keyboard, the switch statement in VKeytoScancode() does not check for VK_LEFT and VK_RIGHT, returning SDL_SCANCODE_UNKNOWN, which in turn does not get mapped to anything (because the scan codes are zeroes).

Likewise for the GLES1 and GLES2 renderers.
This solves the missing pixel at the end of a line and removes all the
heuristics for various platforms/drivers. It's possible we could still use
GL_LINE_STRIP with this and save some vertex buffer space, assuming this
doesn't upset some driver somewhere, but this seems to be a clean fix that
makes the GL renderers match the software renderer output.

* Remove triple buffering support. As far as I can tell, this goes against the libdrm API; the EGL implementations themselves control the buffering. Removing it isn't absolutely necessary as it seemingly works on the Pi at least, but I noticed this while doing my work and explained my reasoning in the commit.
* Replace the crtc_ready logic which allocates an extra bo to perform the initial CRTC configuration (which is required before calling drmModePageFlip) with a call to drmModeSetCrtc after the front and back buffers are allocated, avoiding this allocation.
* Standardized the SDL_*Data variable names and null checks to improve readability. Given that there were duplicate fields in each SDL_*Data structure, having generic names such as "data" at times was very confusing.
* Removed unused fields from the SDL_*Data structures and moves all display related fields out of SDL_VideoData and into SDL_DisplayData. Not required since the code only supports a single display right now, but this was helpful in reading and understanding the code initially.
* Implement KMSDRM_GetDisplayModes / KMSDRM_SetDisplayMode to provide dynamic modeset support.
These changes have been tested on a Raspberry Pi 4 and a Dell XPS laptop with an HD 520.
As an update, I went back over the triple buffer changes and left them in. I didn't entirely get the code originally, I had just seen it calling KMSDRM_gbm_surface_lock_front_buffer twice for a single swap and had removed it because I was paranoid of bugs stemming from it while working on the modeset changes.
I've made a few small changes to the logic that had thrown me off originally and rebased the changes:
* The condition wrapping the call to release buffer was incorrect.
* The first call to KMSDRM_gbm_surface_lock_front_buffer has been removed. I don't understand why it existed.
* Added additional comments describing what was going on in the code (as it does fix the buffer release pattern of the original code before it).

Dualshock4 on bluetooth need 78 bytes for the rumble data while SDL_HIDAPI_RumbleRequest can only hold 64 bytes.
'volatile' is not meant for thread synchronization.
The list of rumble request could grow infinitely if user call SDL_JoystickRumble too much. The documentation says "Each call to this function cancels any previous rumble effect", so overwriting pending request seem like a good idea.
This fixes a crash whereby SDL could crash on macOS/Darwin, if and when a
USB game controller gets unplugged. SDL was not retaining a reference
to the controller's OS/IOKit-provided 'device object', and was capable
of trying to use it, after a device was hot-unplugged.
There is now a thread that handles all HIDAPI rumble requests and a lock that guarantees that we're not reading and writing the device at the same time.
The index and indices were swapped; Which is fine as long as there are
no gaps in the ABS_HAT* event availability but otherwise things do get confused.

To be precise, this is about *desktop OpenGL* on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above.
To shine some light on why this is needed:
In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that *requires* the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.)
Some example code:
https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e
Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation.
The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX.
I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

The current handling of Wayland mouse pointer events only handles wl_pointer.axis events, which, according to the Wayland documentation, deal with mouse wheel scroll events on a continuous scale. While this is reasonable for some input sources (e.g. touchpad two-finger scrolling), it is not for mouse wheel clicks which generate wl_pointer.axis events with large deltas.
This patch adds handling for wl_pointer.axis_discrete and wl_pointer.frame events and prefers to report SDL_MouseWheelEvent in discrete units if they are available. This means that for mouse wheel scrolling we count in clicks, but for touchpad two-finger scrolling we still use whatever units Wayland uses. This behaviour is closer to that of the X11 backend.
Since these events are only available since version 5 of the wl_seat interface, this patch also checks for this and falls back to the previous behaviour if its not available. I also had to add definitions for some of the pointer and keyboard events specified in versions 2-5 but these are just stubs and do nothing.
Make sure the thread is actually paused, and context backep-up, before
SurfaceView is destroyed (eg surfaceDestroyed() actually returns).
Add a timeout when surfaceDestroyed() is called, and check 'backup_done' variable.
It prevents crashes like:

I took the liberty of rewriting this function a bit as it seemed to be unnecessary extended with ifs regarding flags (we can check everything in one pass which seem to be the thing which confuses Visual C++ 2019 as well).
Also, I have made CPU features an int instead of uint because if we check it against flags which are all ints it might as well just be int (no signed/unsigned bitwise comparison).

This kind of blending is rather quite useful and in my opinion should be available for all renderers. I do need it myself, but since I didn't want to use a custom blending mode which is supported only by certain renderers (e.g. not in software which is quite important for me) I did write implementation of SDL_BLENDMODE_MUL for all renderers altogether.
SDL_BLENDMODE_MUL implements following equation:
dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA))
dstA = (srcA * dstA) + (dstA * (1-srcA))

I think I did cover all possibilities within included patch, but I didn't write any tests for SDL_BLENDMODE_MUL, so it would be lovely if someone could do it.
This sequence works across Microsoft, PowerA, PDP, and HORI controllers.
The newer Microsoft XBox firmware requires synchronizing the rumble sequence number, when SDL sees it after the initial connect
The Razer Wildcat controller requires waiting for init responses before continuing the initialization sequence.
The PDP Battlefield 1 controller takes over a second to be ready for initialization, and if initialization is attempted before then, it will fail.
Use XGetKeyboardControl to initialize the current XKeyboardState, and
skip XAutoRepeatOn invocation if global_auto_repeat is AutoRepeatModeOn.
This fixes SDL2 when the X11 client is untrusted.
Do not try to guess MIT_SHM extension availability from the string
returned by XDisplayName, use the appropriate API instead.
This fixes SDL2 inside hasher.

On my system, SDL_GetPowerInfo() returns -1 seconds of battery life left. I have quickly investigated that in my case SDL uses sys interface to get battery data. It tries to read "time_to_empty_now" file which is not always present. However, it is still possible to calculate remaining lifetime using "energy_now" and "power_now" files. This is what my simple patch (included as attachment) tries to accomplish.
Best wishes.

The function we currently use, IOHIDDeviceRegisterRemovalCallback(), often
fails on Catalina with a "__CFRunLoopModeFindSourceForMachPort returned NULL"
error message. Once a removal callback is missed, we will eventually crash when
the joystick is closed attempting to use the invalid IOHIDDeviceRef.

This was something rather trivial to add, but asked at least several times before (I did google about it as well).
It should be possible to dynamically change scaling mode of the texture. It is actually trivial task, but until now it was only possible with a hint before creating a texture.
I needed it for my game as well, so I took the liberty of writing it myself.
This patch adds following functions:
SDL_SetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode scaleMode);
SDL_GetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode *scaleMode);
That way you can change texture scaling on the fly.
Using Wii U GameCube USB adapter with multiple controllers attached and
restarting SDL input in a game results in extra joysticks with NULL name.
HIDAPI_CleanupDeviceDriver() shut down joysticks by iterating through
device->num_joysticks but each HIDAPI_JoystickDisconnected() decreases
device->num_joysticks and shifts joysticks array down. Resulting in only
half of controllers being shutdown. It worked with only 1 controller
attached though.
Disconnect HIDAPI device joystick 0 until there are none left.
Message in the log, when going to background:
"call to OpenGL ES API with no current context (logged once per thread)"
Because of SDL_WINDOWEVENT_MINIMIZED is sent from the Java Activity thread.
It calls SDL_RendererEventWatch(), _WindowEvent() and glFinish() without context.
Solution is to move sending of SDL_WINDOWEVENT_MINIMIZED to the SDL thread.
Added the functions SDL_JoystickFromPlayerIndex(), SDL_JoystickSetPlayerIndex(), SDL_GameControllerFromPlayerIndex(), and SDL_GameControllerSetPlayerIndex()
For some obscure reason, the order in which the libdrm/libgbm libraries
are loaded matters.
Without this fix, the first call to check_modesetting() will work and
load then unload all symbols properly, but the second call to this
function will lock up as soon as dlopen() is called on libdrm.
Swapping the order in which the libdrm and libgbm libraries are loaded
is enough to fix (or work around?) this issue.

I realized I made a minor mistake in my patch: I changed the constructor prototype for SDL_DisplayData, but didn't update the declaration in the .h file. The compiler and linker don't complain, but it would probably be best to fix in case a later change runs into a problem from the mismatch. I have attached a patch to fix this.

On a Dualshock 4 controller using hidapi driver, calling SDL_JoystickRumble with a duration too long (SDL_HAPTIC_INFINITY for example) causes the rumble to stop immediately.
This happens because of integer overflow on line 301 of SDL_hidapi_ps4.c
(https://hg.libsdl.org/SDL/file/a3077169ad23/src/joystick/hidapi/SDL_hidapi_ps4.c#l301), which sets expiration time in the past.
