I'm don't think it's a good idea to modify core SDL files, we should limit ourselves to vita specific files.

I dont think SDL_GetKeyboardFocus is platform dependant so it could be tricky.

When running this little test program with SDL2 on Wayland it often crashes in SDL_Init.

From a backtrace it is apparent that there is a race condition in creating a xkb_context_ref. Sometimes it is 0x0.

By moving the relevant lines higher up in Wayland_VideoInit (in SDL2-2.0.4/src/video/wayland/SDL_waylandvideo.c:302) this seems to get fixed.

I moved the call to WAYLAND_xkb_context_new() up to before the call to WAYLAND_wl_display_connect().

Here is the test program (just a loop of init and quit), and a backtrace from gdb:

#include <cstdio>
#include <stdlib.h>
#include <SDL2/SDL.h>
#include <unistd.h>
#include <iostream>

int main(int argc, char **argv)
{
    int count = atoi(argv[1]);

    for (int i = 0; i < count; i++) {
        std::cout << "Init " << i << std::endl;
        if (SDL_Init(SDL_INIT_VIDEO) < 0) {
            SDL_LogError(SDL_LOG_CATEGORY_APPLICATION,
                         "Couldn't initialize SDL: %s\n",
                         SDL_GetError());
            return 1;
        }
        std::cout << "Quit" << std::endl;
        SDL_Quit();
    }
    return 0;
}

When writing JNI code, one has to make sure all local references are released otherwise the app end up crashing.

I noticed that after updating SDL to 2.0.6 my application now exports SDL_main.

At GitHub SDL mirror (branch 2.0.5) SDL_main prototyped as
extern C_LINKAGE int SDL_main(int argc, char *argv[]);
but at branch 2.0.6 prototype is
extern C_LINKAGE DECLSPEC int SDL_main(int argc, char *argv[]);

Some issue with this commit:
https://hg.libsdl.org/SDL/rev/4130b92b6be4

There is a memory allocation missing.

A listener thread has been added to know when the native thread would end.
But now, it is more easy to only check that after the main function has returned. It's one thread less.

In src\joystick\android\SDL_sysjoystick.c in SDL_SYS_JoystickDetect when SDL_GetTicks return number grater 2147483648 (after 24.85 days uptime) SDL_TICKS_PASSED(SDL_GetTicks(), timeout) return FALSE and Android_JNI_PollInputDevices is never calling.
And in JoystickByDeviceId - when search for newly added joystic - after SDL_SYS_JoystickDetect item not reinitilized, and always stay NULL, cause return NULL instead of added joystick.
the cursor's hotspot simply wasn't translated to it's CSS equivalent, yet
see https://developer.mozilla.org/en-US/docs/Web/CSS/cursor?v=example#Syntax. no explicit hotspot if (0|0) for compatibility with Edge and IE, which indeed don't support custom hot spots
Allow better coexistence between RPI's vendor libraries and VC4 mesa driver.
* The brcmGLESv2 vendor library also supports ES PVR/1 profiles
* Fallback to standard Mesa libraries if the VC4 driver is loaded

Add support to be able to set EGL_SURFACE_TYPE bits when creating an EGL config. This is usefule when wanting to create pixel buffer surfaces in custom video drivers.
We're going to push the manifest environment variables from the Java side instead of continually querying for them from the native side.
Sylvain

What about getting some return code instead of creating another native function.

Remove static int vm_error and vm_event, use local variables instead.

This fixes unused variable errors when compiling with SDL_VIDEO_DRIVER_X11_XINERAMA undefined.

src/video/x11/SDL_x11modes.c:505:22: error: unused variable 'vm_error' [-Werror,-Wunused-variable]

Apparently this still triggers a compiler warning, have to dig further.
Also remove enabling VK support for Mir
… SDL_AUDIO_DISABLED is on

Manuel Sabogal

If SDL is compiled with the Audio subsystem disabled there are some undefined references to the functions ANDROIDAUDIO_ResumeDevices and ANDROIDAUDIO_PauseDevices in the file src/video/android/SDL_androidevents.c.

Patch to support building the tests with cmake.
Disabled by default, use: "cmake .. -DSDL_TEST=YES" to enable the tests.

Tested on macOS 10.13 with the ninja, makefile, and Xcode generators, and Windows 10 with the Visual Studio 2017 generator.

Normal case
1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread.
2. [thread 1] If successful, it calls SDL_SemWait.
3. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost.
4. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free.

Crash case (Segmentation fault)
1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread.
2. [thread 1] If successful, it calls SDL_SemWait.
--> Error return due to SIGNAL(SYSTEM or Real Time) at sem_wait(pthread).
3. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free.
4. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost.
--> Segmentation fault at strlen or sem_post.
This tries to load vulkan.framework or libvulkan.1.dylib before MoltenVK.framework
or libMoltenVK.dylib. In the previous version, layers would not work for applications
run-time loading the default library.
…ck!).

"What I have done is use TerminateProcess rather than ExitProcess.
ExitProcess will cause Microsoft's leak detection to continue, TerminateProcess
won't. It is also technically wrong to use ExitProcess in the case of aborting
the application.

This lets the message box have an icon. Unless the app has opted-in to using
the v6 common controls, though, this will fall back to the usual SDL message
boxes.
These can return to revision control once we ship.

Without this change the drawable had a size of 0 and the metal renderer asserted because the projection matrix wasn't set.

http://hg.libsdl.org/SDL/rev/5ce3f8bf8381 resulted in an error and
two warnings when compiled with mingw.

1.  Error from SDL_windowstaskdialog.h:
In file included from src/video/windows/SDL_windowsmessagebox.c:29:0:
src/video/windows/SDL_windowstaskdialog.h:23:54: error: expected ')' before 'HWND'

This is fixed by removing unnecessary annotations:

2.  Warning from SDL_assert.c:
src/SDL_assert.c: In function 'SDL_ExitProcess':
src/SDL_assert.c:138:1: warning: 'noreturn' function does return

Indeed ExitProcess() is prototyped with DECLSPEC_NORETURN, but
TerminateProcess() is not.  This can be rectified by adding an
exit() call in there. Do NOTE, however, that requires building
with a libc:

3.  Warning from SDL_windowsmessagebox.c:
src/video/windows/SDL_windowsmessagebox.c: In function 'WIN_ShowMessageBox':
src/video/windows/SDL_windowsmessagebox.c:513:9: warning: 'nCancelButton' may be used uninitialized in this function

My lazy solution was manually initializing nCancelButton to 0.
