The Emscripten support for setting window icons introduced in #14490 does not work when using pthreads. Using `SetWindowIcon` will cause the program to crash. The reason for that is that the `Blob` constructor does not accept shared memory (`SharedArrayBuffer`).
We need to create a local copy of the icon data if necessary.
* Implemented EnumerateStorageDirectory()
* Implemented RemoveStoragePath()
* Fixed init failure if the application previously crashed with a write batch in progress
* Allow creation of multiple Steam storage objects, the write batch is complete when the last storage is closed
* Check to see if a file exists in GetStoragePathInfo()
If you want access to the SDL_REVISION define,
you must explicitly include this header.
Language like this was present in the SDL2 version,
but disappeared in SDL3, even though it's still true.
This reverts commit a3992f504c.
The reason SDL_revision.h was not included by SDL.h or SDL_version.h is because SDL_revision.h changes with every git commit, causing a complete SDL rebuild for every trivial git commit.
* GPU: D3D12: Missing WinPixEventRuntime.dll now logs warning at device creation time.
* GPU: D3D12: Debug label functions are now a no-op when WinPixEventRuntime.dll is missing.
* Docs: GPU: Debug function documentation now notes WinPixEventRuntime.dll is required under D3D12.
In the unlikely case that the overflow check should fail,
the else clause would switch to the truncated stack message
without updating the len variable. This would contain the
return value from vsnprintf(), meaning it could point beyond
the buffer.
The subsequent code which trims NL and CR from the buffer,
would then read -- and possibly write -- out-of-bounds.
To fix this, we split the two joint conditions into separate
if-clauses, and adjust the len variable in the case where we
know the message buffer was truncated.
We already set the main thread when creating a thread or calling SDL_Init(), and applications can call SDL_SetMainReady() themselves for special cases, so there isn't a lot of value of forcing everyone through the SDL_RunApp() flow.
