Visual C++ 2013 Update 4 re-introduced the Sleep() function to WinRT apps (for
code that targets Windows 8.1 and Windows Phone 8.1). This led to a build
error, as SDL was defining it's own Sleep() function (to make up for the lack
of a public Sleep() function). The fix makes sure that SDL's custom Sleep()
function is only used when Windows' Sleep() is not available.
Many thanks go out to Sergiu Marian Gaina for the fix!
This would fail if the compiler was given a .m file _and_ no "-o" option; it
would fail to automatically calculate the correct .o filename in this
situation.
Thanks to Ethan Lee for the help tracking this one down!
Only the first-pressed finger wpuld get reported as having moved (via SDL's
touch APIs). Subsequently pressed fingers wouldn't report as being moved, even
though the OS was reporting (to SDL) that they had moved.
These variants include:
- Windows 8.0 for x86
- Windows 8.0 for x64
- Windows 8.0 for ARM
- Windows 8.1 for x86
- Windows 8.1 for x64
- Windows 8.1 for ARM
- Windows Phone 8.0 for x86 (for use with the Windows Phone emulator)
- Windows Phone 8.0 for ARM
- Windows Phone 8.1 for x86 (for use with the Windows Phone emulator)
- Windows Phone 8.1 for ARM
The crash would occur when a WinRT app explicitly tried to create an
SDL_Renderer using the "opengles2" renderer (via SDL_HINT_RENDER_DRIVER), but
OpenGL ES 2 / ANGLE .dlls weren't packaged in the app.
The "future-dev" branch of MSOpenTech's ANGLE/WinRT repository (at
https://github.com/msopentech/angle) includes support for Windows Phone 8.1.
This change allows it to be used in conjunction with SDL's OpenGL functions.
ANGLE for WinRT has at least two versions:
- an older version, which supports Windows 8.0 and 8.1. This is currently
the "winrt" branch in MSOpenTech's ANGLE repository (at
https://github.com/msopentech/angle)
- a newer version, which drops support for Windows 8.0, but is under more
active development (via MSOpenTech's "future-dev" branch), and which was
recently merged into the ANGLE project's official "master" branch
(at https://chromium.googlesource.com/angle/angle)
Both versions are setup using slightly different APIs. SDL/WinRT will now
attempt to detect which version is being used, and configure it appropriately.
The script was originally written for an SDL_gamecontrollerdb.h which had groups
of mappings separated by single lines starting with a "#". This was changed some
time ago to #endif/#if pairs. Because the script assumed only a single #endif in
the whole file it no longer worked correctly and only processed the first group.
The return value of SDL_malloc() was not checked and NULL therefore not handled.
Also added setting of error message for the other SDL_malloc() in this function.
Nitz
Variable entry going out of scope leaks the storage it points to, at:
/* Need to add a hint entry for this watcher */
hint = (SDL_Hint *)SDL_malloc(sizeof(*hint));
if (!hint) {
return;
}
Patch is attached.
The return value of SDL_malloc() was not checked and NULL therefore not handled.
NULL returned by SDL_GameControllerMapping()/SDL_GameControllerMappingForGUID()
now either means "no mapping" (as before) or "no memory" (just crashed before).
For consistency with the similar functions getting SDL_GameController as input.
Also NULL is no SDL_GameController and therefore can not have a mapping anyway.
- made keycode listings a bit easier to read
- listed VK_ keycode names, where appropriate
- removed a few pieces of dead + commented-out code
- applied a common 'WINRT_' prefix to internal function names
