[PATCH 0/5] MR7317: Server-side thread priorities implementation (Part 2)
by Marc-Aurel Zent (＠mzent) 17 Feb '25

17 Feb '25

This adds Mach thread priority support (both in the application and realtime band) and recalculates thread priorities when the process priority changes. Part 3, which is still a bit WIP deals with implementing priority boosts (for main threads and threads which are processing window messages), effectively fully replacing https://gitlab.winehq.org/wine/wine/-/merge_requests/1232. Currently the implementation in this MR already technically overrides what https://gitlab.winehq.org/wine/wine/-/merge_requests/1232 does, if it makes sense I can also revert it here. I added a few comments regarding the Mach thread priority API usage, as there is limited documentation available, and much was inferred from the source or by testing. If this is too verbose I can also remove that... -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7317

[PATCH 0/1] MR7346: msvcrt/tests: Add missing parameter pmode to _open call (ASan).
by Bernhard Übelacker (＠bernhardu) 17 Feb '25

[PATCH v2 0/1] MR7231: rpcrt4, winedbg, winevulkan: Various small fixes for Clang 20 + -Werror.
by William Horvath (＠whrvth) 17 Feb '25

17 Feb '25

I don't think these are serious problems, but Clang 20's defaults (from llvm-mingw nightly) were resulting in build failures with `--enable-werror` due to `-Wtautological-compare` and `-Wunused-function`. I hope that the buffer wrap checking is somewhat idiomatic/standard. If necessary, I can split off the winevulkan change, but it seems minor enough to be grouped in this MR. -- v2: rpcrt4: Pointer arithmetic fixes (-Wtautological-compare). https://gitlab.winehq.org/wine/wine/-/merge_requests/7231

[PATCH v3 0/2] MR5360: gdiplus: Check for empty height in bonding box calculation
by James McDonnell (＠ElementalWarrior) 16 Feb '25

16 Feb '25

This resolves the issue in StudioTax where the bounding box dimensions is reported as 0. Because the height is less than 0, the check for height in GdipAddPathRectangle fails, and the X and Y coordinates of the points is never set. I am fairly ignorant of this code, this seems like a good approach, however I am happy for guidance from others more familiar in how gdiplus works. -- v3: gdiplus: Fix text height calculation when exceeding rect gdiplus: Check for NoClip in text height calculation https://gitlab.winehq.org/wine/wine/-/merge_requests/5360
