The DualShock 4 has all elements listed twice: once in the top-level list of
elements, and once in an "Application Collection" element at the top-level.
Each element has a proper cookie with a unique value, so now we descend into
each element collections, but before we add an element to the device's list,
we make sure we don't already have one with that cookie, probably from
another collection or a buggy device.

All CPU detection functions SDL_Has* will return false, even if it is supported by the CPU, if SDL is compiled with MSVC and the target is x64.
The reason for this is that 'CPU_haveCPUID' will return 0 and macro 'cpuid' in SDL_cpuinfo.c is the fallback implementation, which sets all params to zero.
It is safe to assume that cpuid is supported on a CPU that runs windows x64, so CPU_haveCPUID can just return 1, and the empty macro can be replaced with a small wrap around the __cpuid intrinsic.

Starting from version 2.0.1 libsdl fails to build on Debian GNU/kFreeBSD in SDL_cpuinfo.c.
GNU/kFreeBSD defines __FreeBSD_kernel__ but not __FreeBSD__.
The #ifdef __FreeBSD__ check should be extended for __FreeBSD_kernel__, see the attached patch.

On OSX, an SDL app forces a system shutdown to be cancelled. This happens because [SDLAppDelegate applicationShouldTerminate] returns NSTerminateCancel. A better approach is to subclass NSApplication and override terminate to do nothing except call SDL_SendQuit. In response to a system shutdown notification, this allows the normal SDL Quit event processing to occur, and if the app then terminates, system shutdown occurs normally. Please see the attached patch, based on SDL 2.0.1.

On OSX, the app name in the menu bar is not localized. This can be fixed using the following implementation for GetApplicationName in SDL_cocoaevents.m:
static NSString *
GetApplicationName(void)
{
NSDictionary *dict;
NSString *appName = 0;
appName = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleDisplayName"];
if (!appName)
appName = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleName"];
if (![appName length])
appName = [[NSProcessInfo processInfo] processName];
return appName;
}

When building static or shared libraries on cygwin 1.7.25 on Windows 7 (32-bit), I get the following link errors:

The libuuid from e2fsprogs is completely unrelated to the w32api UUID.DLL implib. FWIW, any *NIX software that I've seen obviously wants the e2fsprogs version, but if libuuid-devel is installed (in /usr/lib) then you can't link against the w32api implib with a simple -luuid.
- Use the SDL_AUDIO_MASK_DATATYPE bit when selecting an implementation
where it matters. Previously two existing AUDIO_F32 cases had been
written, but were unreachable.
- Add AUDIO_F32 case for SDL_ConvertSurround_4.
- Fix incorrect pointer arithmetic causing the 2 to 6 channel
conversion for 4 byte audio formats to read and write beyond the end
of the buffer.

Event watchers are being executed on the inverse order they are added because they are added to the head of the SDL_event_watchers list.
Since watchers are allowed to change events before they are reported (they shouldn't, imo), this breaks code that rely on watcher execution order (such as distributed event handling).
An easy scenario to see this behaving weird to the user is if you add an event watcher to check mouse coordinates and check them again in your event loop. If you add the watcher after renderer's one (which always happens after you have initialized renderer), you get the same event but different coordinates.
The proposed patch adds the event watcher in the tail of the list, not in the beginning, and correctly fixes this problem.

Currently the UIKit/EAGL backend for SDL's OpenGL context creation API doesn't support OpenGL ES 3, despite iOS 7+ being capable (on devices with the necessary hardware.)
I have attached a patch to add support. It's also slightly more future-proof, so eventual OpenGL ES 4+ capability on iOS should hopefully work without requiring changes to SDL's UIKit/EAGL backend.

On my Mac OS X system (10.9.1), the SDL_MOUSEWHEEL event reports negative X values when my trackpad scrolls to the right, and positive X values when my trackpad scrolls to the left. This is backwards from what I'd expect, and I don't think it matches the Windows wheel events.
The vertical scroll values are what I'd expect though, and are consistent what gets reported on Windows (positive Y for scrolling up, negative Y for scrolling down.)
This is with "scroll direction: natural" disabled in the OS X trackpad settings (i.e. my scroll direction in non-SDL OS X programs matches what happens in Windows and Linux.)
I also tested with the horizontal scroll on a real mouse (Logitech G500 without custom drivers), and the horizontal scroll values in SDL are still flipped.
I "solved" the issue for myself by changing this line in the Cocoa_HandleMouseWheel function:
float x = [event deltaX];
to this:
float x = -[event deltaX];
I believe it should work fine with that change - I found something similar in another codebase while looking online for my issue - but I haven't tested on anything below Mac OS 10.8.
Besides being a little more simple to use than the earlier IOKit HID API, and
less likely to be deprecated, it also has the added benefit of working with
the Sony DualShock 4 controller in Bluetooth mode out of the box, whereas
the previous API has a bug that makes it report bad data for the
controller.
Cleaned up several other things in this code, having gone over every line of
it. The remaining deprecated calls are also gone.
Testing:
* Set the SDL_HINT_MOUSE_RELATIVE_MODE_WARP hint true, run testsprite2, press Ctrl-R to enter relative mode, alt tab away from the window, then click on the title bar of the window. Didn't get the mouse button release before, and we do now.

The render target usage in controllermap is required if you are forced to use
the app at a different resolution than the one the art has been made for, for
example on Android, where you don't control the resolution.
(The coordinates for each button are hardcoded to the art size, and appear out
of place otherwise)

[Exec] CMake Error at cmake_install.cmake:151 (FILE):

[13:37:43][Exec] "C:/TeamCity/buildAgent/work/2e3d17a492e75daf/Build/libSDL2.so".
The cmake INSTALL project doesn't work because it uses Linux so shared library paths. Windows uses dlls and I think cygwin also uses dlls. I've included this patch. Can you check if it works?
