With the previous change, I get:
1> Creating library C:\projects\SDL\VisualC\Win32\Debug\SDL2.lib and object C:\projects\SDL\VisualC\Win32\Debug\SDL2.exp
1>LINK : error LNK2001: unresolved external symbol __DllMainCRTStartup@12
Andreas Falkenhahn
In src/SDL.c there is this code:
_DllMainCRTStartup(HANDLE hModule,
...
The comment says that this is needed on Watcom C for some reason but why is it included then when building with Visual C as well? Shouldn't it be only included when compiling on Watcom C then?
I'm asking because this code caused me a lot of headaches because I'm building a DLL that contains SDL and I link using /MT and the _DllMainCRTStartup() symbol obviously led to lots of trouble but it wasn't clear to me where the problem was because all I got from the linker was:
LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
So I had to got through each and every object to see what the culprit was. See here for the full story:
https://stackoverflow.com/questions/25067151/lnk2019-unresolved-external-symbol-main-referenced-in-function-tmaincrtstar/48177067#48177067
So if it isn't necessary on Visual C, please just leave that symbol out on Visual C so that it no longer leads to any trouble. Thanks.
Most pthread functions return 0 on success and non-zero on error, but those
errors might be positive or negative, so checking for return values in the
Unix style, where errors are less than zero, is a bug.
Fixes Bugzilla #4039.

This patch allows the user to disable the behaviour that blocks the compositor through a new hint: SDL_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR. This allows tools or other windowed applications to behave properly under KWin.

After updating from 2.0.5 to 2.0.7, Ibus not work anymore(fcitx still works).
Compare with 2.0.5, there are two issues in SDL_ibus.c.
1, SetupConnection always return SDL_FALSE in 2.0.7.
2, 'SetCapabilities' method should be called on 'ibus_conn'.
Patch attached.

dbus_shutdown() is a debug feature which closes all global resources in the dbus library. Calling this should be done by the app, not a library, because if there are multiple users of dbus in the process then SDL could shut it down even though another part is using it.
For example, i had an issue with this in mGBA, which uses both Qt and SDL, both using libdbus. I had a session bus, but no system bus (this was in a flatpak sandbox), and when SDL_DBus_Init() failed to init the system bus it called dbus_shudown() and continued on. This caused issues for Qt when running due to its session bus connections having disappeared beneath it.
"*(void**)pfn = LoadAddress()" would cast the NULL pointer in pfn to a
void**, and then dereference it, which wasn't what we wanted. Replaced with
a clearer cast operation.

SDL_rpivideo driver has 60 frames per second hardcoded in it, this is a problem for games that need to keep pace using VSYNC. I believe that I have found a solution to this. It is based on code in tvservice.c in rpi userland:

I have a DualShock 4 v2 controller with a GUID that's not in the database. There is an existing GUID that is almost identical, with the only difference that I can tell being the reported version string (mine being 8001, database is 8100).
Existing GUID: 050000004c050000cc09000000810000
New GUID: 050000004c050000cc09000001800000
When connected via USB, the GUID matches an existing entry: 030000004c050000cc09000011810000
This is meant to be the desktop-enhanced version of wl_shell. Right now we
just match what the existing wl_shell code does, but there are other areas of
functionality available to us now, that we can fill in later.
This uses the "unstable" API, since this is what ships in Ubuntu 17.10 (as
part of Wayland 1.10), but Wayland 1.12 promotes this to stable with extremely
minor changes. We will add support for the stable version when it makes sense
to do so.
This variable can be set to the following values:
"0" - The indicator bar is not hidden (default for windowed applications)
"1" - The indicator bar is hidden and is shown when the screen is touched (useful for movie playback applications)
"2" - The indicator bar is dim and the first swipe makes it visible and the second swipe performs the "home" action (default for fullscreen applications)
SDL now builds with gcc 7.2 with the following command line options:
-Wall -pedantic-errors -Wno-deprecated-declarations -Wno-overlength-strings --std=c99

This worked in 2.0.5 as normal, but stopped working in 2.0.7. The monitor's resolution doesn't change, a window is created in full screen mode at the virtual desktop resolution instead.
The EGL_GL_COLORSPACE_KHR is an attribute for eglCreate*Surface.
As written in EGL_KHR_gl_colorspace documentation:
Accepted as an attribute name by eglCreateWindowSurface,
eglCreatePbufferSurface and eglCreatePixmapSurface
EGL_GL_COLORSPACE_KHR 0x309D
(...)
A future SDL release will change the borderless window to act more like a normal window that happens to have no chrome, to support windows that draw their own chrome. In the meantime, those applications should set the "SDL_BORDERLESS_WINDOWED_STYLE" hint.

As a new year gift I have implemented the Windows version of SDL_GetWindowBordersSize(). I needed it for auto-selecting a cozy window size for the game I'm currently working on and noticed that it only worked under X11, so I thought it could be a good excuse to contribute back more stuff. The Mercurial patch is attached as a .diff file. Let me know what you think.
Happy 2018 to all the SDL2 devs and users!

PS: Keep in mind that Windows 10 includes the 8px invisible grip borders as part of the frame. There's a way of detecting if Aero/DWM is being used and ask only for the visible rect, but I believe that GetWindowRect() is doing that for a reason and working as intended, so I haven't changed it. (See [2])

- Use a single buffer for various non-changing constants accessed by the GPU, instead of multiple buffers.
- Do the half-pixel offset for points and lines using a transform matrix so we don't need a malloc when rendering.
- Don't add a half-pixel offset for other primitives and textures. This matches D3D and GL render behaviour.
- Remove the half-texel texture coordinate offset since it's not needed now that there's no more half-pixel position offset when rendering a texture.
- Don't try to set texture usage on iOS 8 since it doesn't exist there.
"GetVersionExA is deprecated in windows 8.1 and above's SDK, causing a warning
when building against the win10 SDK. Attached patch cleans up the usage for a
warning-free build.
GetVersionExA was being used to test to see if SDL was running on win9x or
winnt. A quick chat with Ryan on twitter suggested that SDL doesn't
officially support win9x anymore, so the call to this can be outright removed.
As an aside, replacing the call to GetVersionExA with VerifyVersionInfoA (the
recommended path) would have been pointless, as VerifyVersionInfoA only
supports VER_PLATFORM_WIN32_NT and doesn't officially support any other value
for dwPlatformId currently. (And it's probable that win9x SDKs didn't have
VerifyVersionInfo* in them anyway.)"
Fixes Bugzilla #4019.

I have a problem with the SDL_ShowCursor method on Raspberry.
Depending on the context, my application hides or show the mouse cursor with SDL_ShowCursor.
But when calling SDL_ShowCursor(true), the cursor is displayed at 0,0 (and not at last position).
After debugging sources by myself, it seems that the problem is in SDL_rpimouse.c - RPI_ShowCursor:
vc_dispmanx_rect_set( &dst_rect, 0, 0, curdata->w, curdata->h);
should be
vc_dispmanx_rect_set( &dst_rect, mouse->x, mouse->y, curdata->w, curdata->h);
For me, it solves the problem.

HAVE_POLL is correctly defined in SDL_config.h when running configure. However, in the only place where it's used, it's undefined at the start of the file.

As discussed in 2012 the iOS onscreen keyboard hides when you hit RETURN (see https://discourse.libsdl.org/t/on-screen-keyboard-change/19216).
IMO this is a bad idea to not be able to influence this behavior and just recently this was fixed for Android by adding the hint SDL_HINT_ANDROID_RETURN_HIDES_IME in changeset 11768 6ce3bb5e38a5.

There is a tiny bug in the new overscan code for the SDL_renderer.
In SDL_renderer.c, line 1265, the if check for SDL_strcasecmp with "direct3d" needs to be inverted.
Instead of:
if(SDL_strcasecmp("direct3d", SDL_GetCurrentVideoDriver())) {
It should be:
if(0 == SDL_strcasecmp("direct3d", SDL_GetCurrentVideoDriver())) {
This bug causes the "overscan" mode to pretty much be completely ignored in all cases and all things remain letterboxed (as before the feature).
