Doesn't seem to happen manually, but symetrical to the pause handling.
Can be tested by adding:
mNextNativeState = SDLActivity.NativeState.PAUSED;
handleNativeState();
mNextNativeState = SDLActivity.NativeState.RESUMED;
handleNativeState();
mNextNativeState = SDLActivity.NativeState.PAUSED;
handleNativeState();
mNextNativeState = SDLActivity.NativeState.RESUMED;
handleNativeState();
Before, it ends in 'paused' state.
Now, it ends in 'resumed' state.
It may happen to have the sequence pause()/resume()/pause(), before polling
any events.
Before, it ends in 'resumed' state because as the check is greedy.
Now, always increase the Pause semaphore, and stop at each pause.
It ends in 'paused' state.
Related to bug 3250: set up a reconfiguration of SurfaceView holder.
Turn the screen off manually before the app starts
(repro rate is not 100%..)
"Pause" transition will add events:
SDL_WINDOWEVENT_ENTER
SDL_WINDOWEVENT_FOCUS_LOST
SDL_WINDOWEVENT_MINIMIZED
SDL_APP_WILL ENTER BACKGROUND
SDL_APP_DID ENTER BACKGROUND
"Resume" transition will add events:
SDL_APP_WILL ENTER FOREGROUND
SDL_APP_DID ENTER FOREGROUND
SDL_WINDOWEVENT_FOCUS_GAINED
SDL_WINDOWEVENT_RESTORED
If Android application doesn't empty the event loop in between, it enters in
"paused" state when SDL_WINDOWEVENT_RESTORED is fetched.
See bug 3250 for pratical case.
Occurs when application goes to background:
- Java activity is destroying SurfaceView holder and "egl_surface" (in onNativeSurfaceDestroyed())
- While native thread is in Android_GLES_SwapWindow(), prepared to call SDL_EGL_SwapBuffers()
The error is "call to eglSwapBuffers failed, reporting an error of EGL_BAD_SURFACE"
It an be reproduced easily by adding a SDL_Delay(100) at the begining of SDL_EGL_SwapBuffers(),
and putting the application into background.
Use a semaphore to prevent concurrency issues between Java Activity and Native thread code, when using 'Android_Window'.
(Eg. Java sending Touch events, while native code is destroying the main SDL_Window. )
This is the best option for macOS and iOS, the only platforms with Metal.
Pre-Metal versions of these platforms will fall back to OpenGL (ES), as
appropriate.
Huge thanks to Alexander Szpakowski, who worked incredibly hard to get the
Metal renderer to such a high-quality state!
Not only does this fix macOS 10.14 ("Mojave")'s broken NSOpenGLCPSwapInterval
support, it also lets us implement "adaptive vsync" on macOS!
CVDisplayLink is supported back to macOS 10.4 ("Tiger"), so we just use it
universally without version checks and dump NSOpenGLCPSwapInterval, Mojave or
not.
Switching between renderers "software -> opengl -> opengles2 -> software" fails.
"opengl -> opengles2" calls SDL_RecreateWindow() and frees "window->surface"
without marking it as "surface_invalid".

I'm on macOS 10.14 and I think I'm using or around SDL 2.0.9. This is about the menu bar that SDL sets up which looks like:
<App Name> <Window> <View>
1. View menu never proceeds after the Window menu in any Mac application (it is always before).
2. For SDL, the only purpose of the View menu is for a single fullscreen menu item, which is not justifiable enough to reserve space for a menu. The View menu should thus be removed, and the full screen menu item should be added at the end inside of Window's menu. See built in apps like Dictionary, Chess, App Store (on 10.14) that do this.
3. SDL should add a "Close" menu item to the Window's submenu, and it should be the first item. Its key equivalent should map to command w. Without this, you cannot close the game window via this shortcut, and you cannot close the app's About window via this shortcut.
4. Apps typically use "Enter Full Screen" or "Exit Full Screen" depending on context, not "Toggle Full Screen" which is less user friendly -- I personally care about this point the least.
This happens if you try to lock the pointer and (caps & WL_SEAT_CAPABILITY_POINTER) is false
Leading to input->pointer being NULL which ends up bringing the wayland client down (at lease on weston)
Visual Studio doesn't define __ARM_ARCH nor _ARM_NEON, but _M_ARM and _M_ARM64,
so SDL_HasNEON() was bypassed.
PF_ARM_NEON_INSTRUCTIONS_AVAILABLE doesn't see to be defined (but still works
when defined as 19).
Only __ARM_NEON is defined with Android NDK and arm64-v8a
Tested on ndk-r18, ndk-r13 and also Xcode.
(Visual Studio needs a different fix).
Fixes Bugzilla #4409.
* Search for valid encoder in connector when it doesn't have an
encoder ID set.
* Search for valid CRTC in resources and encoder's possible CRTCs
when encoder doesn't have one set.
* Select default mode if CRTC doesn't have a valid one.
* Pick current_mode's W/H/Refresh Rate basing on current and
valid CRTC mode, not the saved one.

After updating to SDL 2.0.9, I got a user report that my app was crashing when closing a SDL_WINDOW_FULLSCREEN window to return to my Qt-based UI. It looks like the dead SDL window is getting a spurious updateLayer call which is causing SDL to dereference a null SDL_WindowData pointer.
For some reason, this only happens when using SDL_WINDOW_FULLSCREEN and not windowed or SDL_WINDOW_FULLSCREEN_DESKTOP. I was also unsuccessful in my attempt to get a simple reproducer for this crash. The Session.cpp code is available 688c4a90d9/app/streaming/session.cpp but I slightly modified it (adding a SDL_PumpEvents() call at 1179 to immediately trigger the issue, otherwise it happened when Qt next pumped the event loop).
The crashing line is:
NSMutableArray *contexts = data->nscontexts;

Even though my game (dhewm3) doesn't use SDL_INIT_JOYSTICK, SDL_PumpEvent() calls SDL_JoystickUpdate() which ends up calling hid_enumerate() every three seconds, and sometimes on my Win7 box hid_enumerate() takes about 5 seconds, which causes the whole game to freeze for that time.

The Dualshock 3's motion sensors don't seem to be reported by the call to EVIOCGBIT but they still send EV_ABS events. Because they're not reported by EVIOCGBIT they're not assigned a proper axis ids and the default of 0 is used, which is the valid id for the left analog sticks left/right axis.

When trying to compile on a Raspberry Pi 3, running Raspbian Stretch (fully updated), a warning appears:
/home/pi/projects/SDL/src/test/SDL_test_memory.c: In function ?SDL_TrackAllocation?:
/home/pi/projects/SDL/src/test/SDL_test_memory.c:112:109: warning: format ?%llx? expects argument of type ?long long unsigned int?, but argument 5 has type ?unw_word_t {aka unsigned int}? [-Wformat=]
snprintf(entry->stack_names[stack_index], sizeof(entry->stack_names[stack_index]), "%s+0x%llx", sym, offset);
Touch device types include SDL_TOUCH_DEVICE_DIRECT (a touch screen with window-relative coordinates for touches), SDL_TOUCH_DEVICE_INDIRECT_ABSOLUTE (a trackpad-style device with absolute device coordinates), and SDL_TOUCH_DEVICE_INDIRECT_RELATIVE (a trackpad-style device with screen cursor-relative coordinates).
Phone screens are an example of a direct device type. Mac trackpads are the indirect-absolute touch device type. The Apple TV remote is an indirect-relative touch device type.
For starters, we need to correctly respond to 0,0 configure after unsetting
fullscreen. Also, turns out that there should be no drawing calls at all
in between eglSwapBuffers and wl_egl_window_resize, as otherwise EGL can
already allocate a wrongly sized buffer for a next frame, so handle those
together.

Maybe we could add some basics warning flags, not to see all warnings, but so that new warnings are caught sooner.
I would go for -Wall -Wextra, and some -Wno-warning for the allowed warnings.
