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.

I'm unable to compile the latest SDL (directly from the repository) even though I disabled every DirectX option since I don't need DirectX.
I allways het these errors:
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1897:1: error: unknown type name 'IDirect3DDevice9'

SDL_RenderClear clears a render target with the wrong color, if the opengles2 renderer driver is used and the target texture's format is SDL_PIXELFORMAT_ARGB8888.
The bug is *not* reproduced if SDL_PIXELFORMAT_ABGR8888 is used as the texture format (the first from the renderer's list).
It is further not reproduced using any of the following renderer drivers: opengl, opengles (apparently powered by Gallium3D), software.
Finally, the correct color can be drawn using SDL_RenderFillRect (instead of SDL_RenderClear).
A few details about the current setup:
- OS: Ubuntu 12.04 for x86_64
- GPU: GeForce GTX 460
- GPU driver version: 331.20-0ubuntu1~xedgers~precise1 (from the xorg-edgers PPA)

Sam,
It appears that the clear just needs to take the render target format into consideration.

AVX is the successor to SSE* and is fairly widely available. As such, it really ought to be detectable.
This functionality ought to be trivial to implement, and not having it means being forced to write an ugly workaround to check for AVX (so that normal SSE can be used if AVX is not available).
Here is an example on detecting AVX from SO (it actually shows ways to cehck for all of teh fancy instructions):

The reasoning behind this change is that source2 in -tools mode has a single OpenGL context that is used with multiple different windows. Some of those windows are created outside the engine (i.e. with Qt) and therefore we need to use SDL_CreateWindowFrom() to get an SDL_Window for those. The requirement for sharing an OpenGL context across multiple different windows is that each window has the same pixel format. To facilitate this, I now set SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT for the main window before calling SDL_CreateWindowFrom(). When I do this, SDL_CreateWindowFrom() will:
1. Set the pixel format of the returned window to the same pixel format as this SDL_Window passed in with the hint
2. The flag SDL_WINDOW_OPENGL will be set on the new window so it can be used for OpenGL rendering.
I only currently implemented this for Win32/WGL so implementing it for other platforms (i.e. X11) remains a TODO.

Some pseudocode that shows how this is used in Source2:
HWND hExternalHwnd; // HWND that was established outside of SDL
// Create main window (happens inside platwindow.cpp)
SDL_Window *mainWindow = SDL_CreateWindow( , SDL_WINDOW_OPENGL .. );
// Create GL context, happens inside rendersystemgl
SDL_GLContext onlyContext = SDL_GL_CreateContext( mainWindow );
// Now I need to create another window from hEternalHwnd for my swap chain that will have the same pixel format as mainWindow, so set the hint
SDL_SetHint( SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT, CFmtStr( %p, mainWindow) );
// Create the secondary window. This returned window will have SDL_WINDOW_OPENGL set and share a pixel format with mainWindow from the hint
SDL_Window *secondaryWindow = SDL_CreateWindowFrom( hExternalHwnd );
// To render to the main window:
SDL_GL_MakeCurrent( mainWindow, onlyContext );
// Do some rendering to main window
// To render to the secondary window:
SDL_GLMakeCurrent( secondaryWindow, onlyContext );
// Do some rendering to secondary window
This fixes weird behavior on Mac where our first responder reverts to the window
itself, rather than the SDLTranslatorResponder, after the window has lost focus
once. This causes Escape to call cancelOperation: on the NSWindow, which by
default removes our fullscreen-ness.
When someone has turned off SDL_TEXTINPUT we should probably set another initial
responder that handles the Escape behavior, so that SDL_TEXTINPUT doesn't change
fullscreen behavior (and possibly other behavior) like it does now.
Previously, we'd minimize fullscreen windows (if
SDL_HINT_VIDEO_MINIMIZE_ON_FOCUS_LOSS was set) during SDL_DestroyWindow if they
had keyboard focus, because we call SDL_SetKeyboardFocus(NULL) which yields a
OnWindowsFocusLost event.

SDL 2.x recently accepted patches to enable OpenGL ES 2 support via Google's ANGLE library. The thought is to try to eventually merge SDL/WinRT's OpenGL code with SDL-official's.

As described in the other thread
(http://lists.libsdl.org/pipermail/sdl-libsdl.org/2013-November/091997.html),
I've run into a case of SDL2 not recognizing a wireless Xbox 360
controller receiver properly on Debian Linux amd64 testing.
Apparently, the generated GUID is slightly different.
Device in question:
Bus 001 Device 015: ID 045e:0291 Microsoft Corp. Xbox 360 Wireless
Receiver for Windows

Steps to reproduce:
1. Grab the cursor with SDL_SetCursorGrab()
2. Alt-tab away from the window
3. Click on the titlebar of the window
This will cause the window to disappear underneath the taskbar!
This appears to be a general issue with ClipCursor() on windows, i.e. I am getting the same behavior if I call ClipCursor() directly.
It is caused by a feedback loop between the ClipCursor function and the modal resize/move event loop that handles mouse-based sizing on Windows.

The SDL_ceil function is implemented incorrectly when HAVE_CEIL is not defined (HAVE_LIBC not defined).
The following code:
double val = SDL_ceil(2.3);
printf("%g", val);
prints "2.0", as STD_ceil is defined as:
double
SDL_ceil(double x)
{
#ifdef HAVE_CEIL
return ceil(x);
#else
return (double)(int)((x)+0.5);
#endif /* HAVE_CEIL */
}
This functions is used in the SDL_BuildAudioResampleCVT function of the audio subsystem (SDL_audiocvt.c), and causes a bug in that function.
Lets Android take care of which is the primary pointer (the one acting as the
mouse in SDL), reorganized the Java side code as well to make it easier to
understand.
If your application wants to have access to the full resolution even when the system has DPI scaling enabled, call SetProcessDPIAware() before calling SDL_Init()
e.g.
typedef BOOL (WINAPI *SetProcessDPIAware_t)(void);
HMODULE hMod = LoadLibrary("user32.dll");
if ( hMod ) {
SetProcessDPIAware_t pSetProcessDPIAware = GetProcAddress( hMod, "SetProcessDPIAware" );
if ( pSetProcessDPIAware ) {
pSetProcessDPIAware();
}
FreeLibrary( hMod );
}
To enable this, set the environment variable SDL_MOUSE_RELATIVE_MODE_WARP to "1"
When mouse relative mode is disabled, put the cursor back where the application expects it to be, instead of where it was when relative mode was enabled.
Based on the original port to Wayland by: Joel Teichroeb, Benjamin Franzke, Scott Moreau, et al.
Additional changes in this commit, done by me:
* Wayland uses the common EGL framework
* EGL can now create a desktop OpenGL context
* testgl2 loads GL functions dynamically, no need to link to libGL anymore
* Assorted fixes to the Wayland backend
Tested on the Weston Compositor (v1.0.5) that ships with Ubuntu 13.10,
running Weston under X. Tests ran: testrendercopyex (all backends), testgl2, testgles2,testintersections

SDL_ltoa(-2147483648,s,10) only returns "-" because there is a bug in the code:
if ( value < 0 ) {
*bufp++ = '-';
value = -value;
}
but -(-2147483648) is still -2147483648 (0x80000000) as signed int (or long), so the following loop doesn't run at all. Similar bug are also in SDL_lltoa.
BTW, there is no sanity check for radix.
SDL_GameControllerAddMappingsFromFile is now a convenience macro.
controllermap can now skip bindings by pressing space or clicking/touching the
screen.

To keep the directory layout sane, we should probably move this one piece of source to the linux catch-all directory, instead of making it look like this is part of an SDL "input" subsystem.

The MMX path in SDL_fillrect.c uses the SSE intrinsic _mm_stream_pi. The function or symbol provided by the compiler will not be present because the SSE header may not get included. The linker will complain about an undefined reference.
Since this is the only intrinsic used here (and someone forgot to create one for MOVQ), I think the MMX path can be removed completely. At least I don't see another way to move 64-bits from an MMX register to memory.

On OS/X after calling SDL_SetWindowBordered right mouse clicks no longer register.
Steps to Reproduce:
1. Open a windowed window on OS/X. (With the border on.)
2. e.button.button will give values 1,2,3 depending on which mouse button I click.
3. Call SDL_SetWindowBordered to disable the border.
4. e.button.button will only give values 1,2. 3 (right mouse button) stops coming through.
Expected result:
I expect all mouse buttons to register.
Haiku uses most of the standard pthread API, with a few #ifdefs where we
still need to fallback onto the old BeOS APIs.
BeOS, however, does not support pthreads (or maybe doesn't support it well),
so I'm unplugging support for the platform with this changeset. Be Inc went
out of business in 2001.

As it turns out, it was impossible to render a texture flipped diagonally (both vertically and horizontally) with one RenderCopyEx call.
With help from #SDL @ freenode, we came up with a fix.
"Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'backgroundWindows not nil in enterFullScreenTransitionWithOptions:animated:activatingIt:'"
To reproduce this, run testsprite2, press Alt-Enter once, again while it's animating to fullscreen, and then again while it's animating out of fullscreen.

Overview: While SDL_SetTextInputRect works perfectly to move my window out of the way of the virtual keyboard using SDL2/Android, on iOS this function has no effect.
Steps to Reproduce: Call SDL_SetTextInputRect with a rect near the bottom of the screen before calling SDL_StartTextInput.
Actual Results: The iOS virtual keyboard is displayed after calling SDL_StartTextInput, but the screen is not shifted to reveal the TextInputRect region.
Expected Results: The screen should be shifted to reveal the TextInputRect region (like with SDL2/Android.)
This patch implements SDL_SetTextInputRect for uikit/iOS.
It sets up notification handlers to respond to changes in the display of the keyboard. These handlers then change the frame of the view so it is moved out of the way of the keyboard as per SetTextInputRect.
This fixes behavior with the new Mac OS X fullscreen space code, as well as improve behavior on Linux desktops.
The default for normal fullscreen mode is still to minimize because we're likely doing a mode switch and don't want to stick around as a borderless window in the background.
