Now multiple XInput controllers map correctly to device indexes instead of grabbing
the first available userid, and are completely separated out from DirectInput.
Also, the hardcoded limitation on number of DirectInput devices is gone. I don't
expect there to really ever be more than eight joysticks plugged into a machine, but
it was a leftover limitation for a static array we didn't actually use anymore.
Fixes Bugzilla #1984. (etc?)
- also adds OS X specific magic for bundled apps adding an Info.plist property of name SDL_FILESYSTEM_BASE_DIR_TYPE to the following values will change the bahaviour.
* bundle -- use the bundle directory e.g. "/Applications/MyGame/Blah.app/"
* parent -- use the bundle parent directory e.g. "/Applications/MyGame/"
* resource -- use the bundle resource directory (default) e.g. "/Applications/MyGame/Blah.app/Contents/Resources/"
- detect that you tried to open a gamecontroller in xinput mode and failed, then re-get the mapping for the dinput variant you did open (and most likely now just fail the open)

This entire function is kind of a mess and more complicated than needed, but I don't want to refactor it too heavily tonight. May look at improving how the indexes are assigned more significanly later. The way it handles not finding a valid "gamepad" type device is also super broken, it leaves in place the xinput bindings but opens the controller with dinput and ends up with completely wrong mappings, not solving that now, but fixing the bug where we'd very frequently not find a controller due to gaps in assigned player numbers should mostly avoid it.

The issue comes down to this line on MSDN:
"TranslateMessage produces WM_CHAR messages only for keys that are mapped to ASCII characters by the keyboard driver."
"WM_KEYDOWN and WM_KEYUP combinations produce a WM_CHAR or WM_DEADCHAR message. WM_SYSKEYDOWN and WM_SYSKEYUP combinations produce a WM_SYSCHAR or WM_SYSDEADCHAR message."
Except for WM_CHAR, none of these messages are used in SDL. Hence TranslateMessage should be dropped entirely and proper handling be included in the WM_KEYDOWN event.
Currently TranslateMessage is called for every message even if it must not be called in certain cases (like "An application should not call TranslateMessage if the TranslateAccelerator function returns a nonzero value.").
WM_CHAR message handling should remain for external processes posting these messages - additionally, WM_UNICHAR should be added.
I made a patch for src/video/windows/SDL_windowsevents.c that seems to work fine. It doesn't solve the "missing" composition for Khmer, but at least input for languages that cannot be mapped to ASCII characters (and for which IME is not used) will now work on Windows.

I found I make a big mistake that when dstA==0, I just simply let *dstp=*srcp and forgot to make dstRGB = srcRGB*srcA.
The if consition "(*dstp & amask) == 0" in BlitRGBtoRGBPixelAlphaMMX and BlitRGBtoRGBPixelAlphaMMX3dNow should be removed.
I see the Remarks of function SDL_BlitSurface shows that "when SDL_BLENDMODE_BLEND, we have dstA = srcA + (dstA * (1-srcA))". however, I tested some pictures but the result implies "dstA=arcA" actually. I stepped into the source code, and found after I set SDL_BLENDMODE_BLEND for the source surface, the final blit function is BlitRGBtoRGBPixelAlphaMMX when I use SDL_BlitSurface on my computer. And I found these codes:
else if (alpha == amask) {
/* opaque alpha -- copy RGB, keep dst alpha */
*dstp = (*srcp & chanmask) | (*dstp & ~chanmask);
The same code is used in BlitRGBtoRGBPixelAlphaMMX3DNOW and BlitRGBtoRGBPixelAlpha. So I think they still keep dst alpha.

If the app is in landscape mode and the user presses the power button, a pause
is followed immediately by a surfaceChanged event because the lock screen
is shown in portrait mode. This triggers a "false" resume.
So, we just pause and resume following the onWindowFocusChanged events.
Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
blocking the event pump.
Some more recent compilers emit SSE aligned store instructions for the loop,
causing crashes if the destination buffer isn't aligned on a 32-bit boundary.
This would also crash on platforms like ARM that require aligned stores.
This fixes a crash inside SDL_FillRect that happens with the official x64 mingw
build.
The Windows Phone 8.1 'MessageDialog' API only seems to support two buttons,
despite the documentation for such mentioning support for three. Trying to use
three or more buttons leads to an exception being thrown. As such, any attempt
to use more than two buttons via SDL_ShowMessageBox (on Windows Phone 8.1) will
lead to no message box getting shown, and the call returning an error.
The Win32 MessageBox and dialog APIs are not available in WinRT apps, to note.
More extensive message dialog support might be available at some point, if and
when XAML support is more fully fleshed-out. I'm not certain of this, though.
When a Windows Phone 8.0 app was rotated to anything but Portrait mode, touch
input coordinates, as well as virtual mouse coordinates, were usually getting
reported as coming from the wrong part of the screen.
If a Windows Phone 8.1 device was rotated to anything but Portrait mode,
the Direct3D 11 renderer's output wouldn't get aligned correctly with the
screen.
This is a step towards supporting "Universal" Windows apps, when building for
Windows Phone. SDL can now build against the Windows Phone 8.1 SDK, and apps
linked to it can run, however further work and testing is required as some
previously Phone-only code appears to no longer be applicable for
Windows Phone 8.1. The Windows 8.1 code paths does seem to be preferable, but
should probably be tested and updated on a finer-grained basis.
If in doubt, use the Windows Phone 8.0 projects for now, as located in
VisualC-WinRT/WinPhone80_VS2012/
TODO:
- look at any Windows Phone specific code paths in SDL, and see if Phone 8.1
should use the Windows Phone code path(s), or the Windows 8.x or 8.1 paths
The Win32 APIs, VerifyVersionInfoW and VerSetConditionMask, are not currently
available for use in WinRT apps. This change primarily #if[n]defs-out some
calls to them.
This allows the joystick hotplug to function without the main event loop
(specifically: without SDL_INIT_VIDEO), and moves explicit polling for
joysticks where it belongs at the low-level: in SDL_SYS_JoystickDetect().
This lets apps call SDL_JoystickUpdate() to get hotplug events and keep
SDL_NumJoysticks() correct, as expected. As SDL_PumpEvents() (and
SDL_PollEvents, etc) calls SDL_JoystickUpdate(), existing apps will function
as before.
Thanks to "raskie" on the forums for pointing this out!
This fixes a bug where we'd offset positions by the height of the dock, if it
was along the bottom of the screen.

Thanks to Alex Szpakowski for bug & patch.
It used to be that SDL_SetWindowPosition was relative to the top of the screen,
which didn't make sense. In addition, borderless windows can be positioned
*below* the menubar, so SDL_SetWindowPosition(win, 0, 0) on a borderless window
would hide ~30ish pixels of the window below the menubar.
This fixes an issue where an empty cliprect is treated the same as a NULL
cliprect, causing the render backends to disable clipping.
Also adds a new API, SDL_RenderIsClipEnabled(render) that allows you to
differentiate between:
- SDL_RenderSetClipRect(render, NULL)
- SDL_Rect r = {0,0,0,0}; SDL_RenderSetClipRect(render, &r);

When I double click on a window, the "clicks" field (newly added since 2.0.2) in SDL_MouseButtonEvent is 1 instead of 2.
However, when I "tripple" click, "clicks" field is then 2.
I'v look into the source code in SDL_windowsevents.c and found that when a double click event comes, WIN_WindowProc will get a WM_LBUTTONDBLCLK msg. The message sequence of a double click is:WM_LBUTTONDOWN->WM_LBUTTONUP->WM_LBUTTONDBLCLK->WM_LBUTTONUP.

Using any SDL application with the Wayland backend under Weston, if the application sets a cursor with SDL_SetCursor, the cursor will work until the mouse pointer leaves the window. When the pointer re-enters the window, there will be no cursor displayed at all.
I did some digging, and the reason for this is that SDL attaches the buffer to the cursor surface only once (during cursor creation) and assumes that it will stay attached. This is not how Wayland works, though - once the compositor is done rendering the buffer, it will release it, so it is no longer attached to the surface. When the cursor re-enters the window a second time, SDL sets the cursor to the same surface with no buffer attached, so no cursor is displayed.
This is fixed by the attached patch, which makes SDL attach the buffer to the surface when the cursor is set, not when it is created.

Wayland_CreateSystemCursor tries to load a cursor named "wait" for two of the system cursor categories. This causes a segmentation fault when one of these cursors is used, because "wait" is not an actual cursor name in X11/Wayland cursor themes.
I can't attach my patch since I'm on a mobile right now, but I can confirm that simply replacing "wait" with "watch" for both of its uses in Wayland_CreateSystemCursor (in SDL_waylandmouse.c) fixes the bug.

RHEL6 and CentOS6 systems still use an old version of udev (147). It wasn't until udev 148 (Yep. 1 version off!) that the input class system changed from "ID_CLASS" to "ID_INPUT_{JOYSTICK,KEYBOARD,MOUSE,etc}" (http://lwn.net/Articles/364728/). Because SDL2 looks for the ID_INPUT_X field this means that it never detects any input devices on RHEL6 systems.
I've attached a patch which fixes the problem. If no input devices are detected with "ID_INPUT_X" then SDL will fallback to looking for the old style "ID_CLASS" udev field instead.
Because of the "big change" between udev versions I doubt it'll ever get upgraded on RHEL6, but because RHEL7 is on the way I don't know if this patch is worth merging. Hopefully it'll help anyone out that's having this problem though.

Hi,
it is possible to skip the bug in libX11 by using the defaults for
XNResourceName and XNResourceClass in `XCreateIC' (the table for the
"Input Context Values" [1] in libX11-doc shows that a default is
provided if it is not set).

While enabling $1 gesture support in the Urho3D engine which uses SDL2 I detected some errors in the gesture code in SDL_gesture.c:
- In the function SDL_SaveAllDollarTemplates() the following line should use index variable j instead of i:
rtrn += SaveTemplate(&touch->dollarTemplate[i], dst);
- In the function SDL_SaveDollarTemplate() the following code should use index variable j instead of i:
if (touch->dollarTemplate[i].hash == gestureId) {
return SaveTemplate(&touch->dollarTemplate[i], dst);
- In the function SDL_SendGestureDollar() the x & y coordinates are being written to the mgesture structure, which results in garbage due to dgesture and mgesture being different data structures inside the union. The coordinates should be written to dgesture.x & dgesture.y respectively
Changes included:
- adding support for a few, additional, VirtualKey constants
- removing accesses to 'windows_scancode_table', as the table's contents
don't line up with WinRT virtual keys. Using Windows older VK_* constants
may, however, be a good alternative in a future update.
