The HORI Wireless Switch Pad does not properly connect via bluetooth. I did some debugging and found that the code that tries to control the Home LED causes this controller to disconnect.
This results in a dlsym() call, which causes Emscripten to panic if the game
wasn't explicitly built dlopen support. eglGetProcAddress works just fine on
this platform, so just let that codepath handle it.
This is a multi-part fix, and is the 2nd attempt at a fix for Bug 5034. Here
are the problems being addressed:
1. On macOS 10.14.x and earlier, trying to call IOHIDDeviceUnscheduleFromRunLoop
without a prior, paired call to IOHIDDeviceScheduleWithRunLoop, appears to
lead to a crash. A per-device flag has been added to make sure that these
calls are paired.
2. DARWIN_JoystickDetect was free'ing its SDL_joystick's hwdata field
(via FreeDevice) without setting it to NULL, and DARWIN_JoystickRumble wasn't
checking for a NULL hwdata. FreeDevice will now set hwdata to NULL and
DARWIN_JoystickRumble will check for a NULL hwdata.

Added Linux implementation, otherwise you get "Unsupported direction type" error.
Added documentation to explain why one would use SDL_HAPTIC_FIRST_AXIS.

Consider a device supporting effects on multiple axes.
There's currently no way to play effects against a single-axis direction.
A device supporting effects against X and Y may not allow to play effects with a two-axis direction coordinate, even if one of the coordinates is null.
My current (ugly) work around for this is to add a direction type SDL_HAPTIC_X_FORCE to play effects against a X-axis only direction (patch attached).
This issue impacted two GIMX users using the following wheels:
- Leo Bodnar SimSteering force feedback wheel
- Accuforce direct drive wheel
Playing constant/spring/damper effects against a X-axis direction worked well for the first wheel, but not for the second one.
A better strategy seems to play the effects against the first axis reported by the DirectInput enumeration.
This strategy also works with Logitech wheels (at least the DFGT).
It's been more than a year that I have the latest patch (playing effects against the first axis only) in the GIMX software. It's being used by thousands of people, mostly for adapting their FFB wheel to the PS4. I had no report that proves this strategy to be wrong.

Add new RawInput controller API, and improved correlation with XInput/WGI
Reorder joystick init so drivers can ask the others if they handle a device reliably
Do not poll disconnected XInput devices (major perf issue)
Fix various cases where incorrect correlation could happen
Simple mechanism for propagating unhandled Guide button presses even before guaranteed correlation
Correlate by axis motion as well as button presses
Fix failing to zero other trigger
Fix SDL_HINT_JOYSTICK_HIDAPI not working if set before calling SDL_Init()
Add missing device to device names
Disable RawInput if we have a mismatch of XInput-capable but not RawInput-capable devices
Updated to SDL 2.0.13 code with the following notes:
New HID driver: xbox360w - no idea what that is, hopefully urelated
SDL_hidapijoystick.c had been refactored to couple data handling logic with device opening logic and device lists caused some problems, yields slightly uglier integration than previously when the 360 HID device driver was just handling the data.
SDL_hidapijoystick.c now often pulls the device off of the joystick_hwdata structure for some rumble logic, but it appears that code path is never reached, so probably not a problem.
Looks like joystick_hwdata was refactored to not include a mutex in other drivers, maintainers may want to do the same refactor here if that's useful for some reason.
Something changed in how devices get names, so getting generic names.
Had to fix a (new?) bug where removing an XInput controller caused existing controllers (that moved to a new XInput index) to get identified as 0x045e/0x02fd ("it's probably Bluetooth" in code), rendering the existing HIDAPI_IsDevicePresent and new RAWINPUT_IsDevicePresent unreliable.

I get a build error in SDL_sysjoystick.c:74 for the merged patch, but its nothing to sweat about, just -Werror=declaration-after-statement doing its usual stuff.
David Ludwig
I have created a new driver for SDL's Joystick and Game-Controller subsystem: a Virtual driver. This driver allows one to create a software-based joystick, which to SDL applications will look and react like a real joystick, but whose state can be set programmatically. A primary use case for this is to help enable developers to add touch-screen joysticks to their apps.
The driver comes with a set of new, public APIs, with functions to attach and detach joysticks, set virtual-joystick state, and to determine if a joystick is a virtual-one.
Use of virtual joysticks goes as such:
1. Attach one or more virtual joysticks by calling SDL_JoystickAttachVirtual. If successful, this returns the virtual-device's joystick-index.
2. Open the virtual joysticks (using indicies returned by SDL_JoystickAttachVirtual).
3. Call any of the SDL_JoystickSetVirtual* functions when joystick-state changes. Please note that virtual-joystick state will only get applied on the next call to SDL_JoystickUpdate, or when pumping or polling for SDL events (via SDL_PumpEvents or SDL_PollEvent).
Here is a listing of the new, public APIs, at present and subject to change:
------------------------------------------------------------
/**
* Attaches a new virtual joystick.
* Returns the joystick's device index, or -1 if an error occurred.
*/
extern DECLSPEC int SDLCALL SDL_JoystickAttachVirtual(SDL_JoystickType type, int naxes, int nballs, int nbuttons, int nhats);
/**
* Detaches a virtual joystick
* Returns 0 on success, or -1 if an error occurred.
*/
extern DECLSPEC int SDLCALL SDL_JoystickDetachVirtual(int device_index);
/**
* Indicates whether or not a virtual-joystick is at a given device index.
*/
extern DECLSPEC SDL_bool SDLCALL SDL_JoystickIsVirtual(int device_index);
/**
* Set values on an opened, virtual-joystick's controls.
* Returns 0 on success, -1 on error.
*/
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualAxis(SDL_Joystick * joystick, int axis, Sint16 value);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualBall(SDL_Joystick * joystick, int ball, Sint16 xrel, Sint16 yrel);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualButton(SDL_Joystick * joystick, int button, Uint8 value);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualHat(SDL_Joystick * joystick, int hat, Uint8 value);
------------------------------------------------------------
Miscellaneous notes on the initial patch, which are also subject to change:
1. no test code is present in SDL, yet. This should, perhaps, change. Initial development was done with an ImGui-based app, which potentially is too thick for use in SDL-official. If tests are to be added, what kind of tests? Automated? Graphical?
2. virtual game controllers can be created by calling SDL_JoystickAttachVirtual with a joystick-type of SDL_JOYSTICK_TYPE_GAME_CONTROLLER, with naxes (num axes) set to SDL_CONTROLLER_AXIS_MAX, and with nbuttons (num buttons) set to SDL_CONTROLLER_BUTTON_MAX. When updating their state, values of type SDL_GameControllerAxis or SDL_GameControllerButton can be casted to an int and used for the control-index (in calls to SDL_JoystickSetVirtual* functions).
3. virtual joysticks' guids are mostly all-zeros with the exception of the last two bytes, the first of which is a 'v', to indicate that the guid is a virtual one, and the second of which is a SDL_JoystickType that has been converted into a Uint8.
4. virtual joysticks are ONLY turned into virtual game-controllers if and when their joystick-type is set to SDL_JOYSTICK_TYPE_GAMECONTROLLER. This is controlled by having SDL's default list of game-controllers have a single entry for a virtual game controller (of guid, "00000000000000000000000000007601", which is subject to the guid-encoding described above).
5. regarding having to call SDL_JoystickUpdate, either directly or indirectly via SDL_PumpEvents or SDL_PollEvents, before new virtual-joystick state becomes active (as specified via SDL_JoystickSetVirtual* function-calls), this was done to match behavior found in SDL's other joystick drivers, almost all of which will only update SDL-state during SDL_JoystickUpdate.
6. the initial patch is based off of SDL 2.0.12
7. the virtual joystick subsystem is disabled by default. It should be possible to enable it by building with SDL_JOYSTICK_VIRTUAL=1
Questions, comments, suggestions, or bug reports very welcome!

Basically replicating the solution of the Switch Controller's button label issue. Physical layout should take priority unless it's explicitly requested by the user or application!

In `SDL_iconv_string` the `while (inbytesleft > 0)` loop can end up in a state where it never terminates because the library `iconv` function called from `SDL_iconv` doesn't consume any bytes.
This happened when a `WCHAR_T` input string was being converted to `UTF-8` but contained invalid characters. It would first It would first skip a few bytes due to `case SDL_ICONV_EILSEQ` but when there were 3 bytes remaining of `inbytesleft` `iconv` just didn't consume anything more (but didn't throw an error either).
It just so happens that the Microsoft Classic IntelliMouse `product_string` contains such invalid characters (`"Microsoft? Classic IntelliMouse?"`), meaning the function would get stuck with said mouse plugged in.
A fix for this would be to check if `inbytesleft` was unchanged after an iteration and in that case either decrement the counter like when `SDL_ICONV_EILSEQ` is returned or simply break the loop.

Hi, i already mentioned in the SDL discourse a bug that recreating of a texture occours pixel shader problem on direct3d renderer. There is no problem for direct3d11. You can see the issue by using my app named C Media Player which is available for Windows for free using my web site www.cmediaplayer.com. Just follow the steps:
*Open a media file
*When playing the file change the scale quality under the video menu.
*You will see the problem.
Prior to this fix, we would hit the existing_instance >= 0 case and move the joystick
again to a different index than the one requested by the caller. It also breaks the assumption
that a SDL_JoystickID is only present in SDL_joystick_players at one location.

I was just communicating with one of the Retropie developers regarding this.
This change removed the forced window focus change on creation (3534cb3793) as part of the change no longer assumes there's only a single window being created. This was perhaps an over-aggressive removal.
Due to that change, joystick events are only received if SDL_SetKeyboardFocus is called explicitly, or if the app has specified SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS.
I think that part of my change should be reverted to continue setting mouse / keyboard focus to the window being created. If SDL_WINDOW_INPUT_FOCUS is to be used as an input flag the code could be conditional, but that would still leave existing software broken.
The 8BitDo SF30 Pro Gamepad will generate a single motor pulse for each rumble message, so we need to do this frequently to have continous rumble on this device.

KaiOS is an OS for feature phones, with numeric keypad and non-touch screen, and typically 512 Mb RAM and 4 Gb flash.
It is based on Firefox OS, all apps are made with HTML5 and Javascript. SDL can be cross-compiled using emscripten and packaged as native app.
This patch adds support for star '*' and pound '#' keys on such phones to generate SDL events.
It appears that with some (presumably) flaky drivers or hardware that the WriteFile in hid_write never completes leading to GetOverlappedResult to block forever waiting for it.

When I run SDL_INIT with SDL_INIT_JOYSTICK it stalls for about 10 seconds (last report was 10,615ms), but only if I'm currently playing audio. (Like in Spotify for example.)
querying something related to device access (last dll loaded)

I use a USB DAC because my mobo's audio out is pretty not great. And I've noticed unplugging it seems to solve the issue. I haven't noticed any other issues that are caused by my DAC.

This patch fixes the segfault on my Pi, though the valid display index range reported by the CHECK_DISPLAY_INDEX() macro in src/video/SDL_video.c is a little weird:
$ SDL_VIDEO_EGL_DRIVER=libEGL.so SDL_VIDEO_GL_DRIVER=libGLESv2.so ./a.out
SDL_Init(): displayIndex must be in the range 0 - -1

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.
