[PATCH v4 0/1] MR2153: win32u: invalidate all cached keys after input
by Henry Goffin (＠AMZN-hgoffin) 28 Feb '23

28 Feb '23

This patch addresses an issue in Second Life and potentially other multi-threaded applications which process WM_KEYDOWN in one thread and then verify that the key is "still down" with GetAsyncKeyState from another thread. Wine uses a per-thread key cache, resulting in inconsistent views of key status. Caches are now invalidated when an input event is injected by the driver or via SendInput. -- v4: win32u: invalidate all cached keys after input https://gitlab.winehq.org/wine/wine/-/merge_requests/2153

[PATCH 0/1] MR2302: gdiplus: Use FILE_SHARE_READ in GdipPrivateAddFontFile().
by w-flo (＠w-flo) 28 Feb '23

28 Feb '23

ZusiDisplay sometimes loads the same font file into two different PrivateFontCollections using two threads, so there is a race condition when the file is opened without the FILE_SHARE_READ sharing mode. The second call to GdipPrivateAddFontFile() might fail if the first one hasn't closed the file handle yet. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2302

Actually the WARN() in wined3d_context_gl_set_gl_context() is probably enough already, so disregard this. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2299#note_25755

[PATCH v13 0/4] MR84: vkd3d-shader/spirv: Merge all shader IR fork and join phases into a single phase.
by Conor McCarthy (＠cmccarthy) 28 Feb '23

28 Feb '23

Normalise the incoming vkd3d_shader_instruction IR to the shader model 6 pattern where only one patch constant function is emitted. This allows generation of a single patch constant function in SPIR-V. -- v13: vkd3d-shader/spirv: Declare the phase SPIR-V function in spirv_compiler_enter_shader_phase(). vkd3d-shader/spirv: Remove the hull shader phase array. vkd3d-shader/trace: Trace the normalised instruction array after tracing the input. vkd3d-shader/ir: Merge all shader IR fork and join phases into a single phase. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/84
