[PATCH v3 0/2] MR9398: Don't try to activate a window in set_window_pos if it's set as active in GUITHREADINFO.

This prevents a window from getting reactivated when calling `SetWindowPos` inside the WM_ACTIVATE handler. For now I only was able to reproduce this by triggering a change in the active window from X11 with an alt-tab or by clicking another window, I was not able to write a wine test for this. This test program works for reproducing it. ```c #include <windows.h> LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) { if (uMsg == WM_ACTIVATE) { SetWindowPos(hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); } done: return DefWindowProc(hwnd, uMsg, wParam, lParam); } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR pCmdLine, int nCmdShow) { HWND hwnd; const char CLASS_NAME[] = "class"; WNDCLASSA wc = {}; wc.lpfnWndProc = WindowProc; wc.hInstance = hInstance; wc.lpszClassName = CLASS_NAME; RegisterClass(&wc); hwnd = CreateWindowEx(0, CLASS_NAME, "test", 0, 4, 4, 1024, 768, NULL, NULL, hInstance, NULL); ShowWindow(hwnd, SW_SHOW); MSG msg; while (TRUE) { GetMessage(&msg, NULL, 0, 0); TranslateMessage(&msg); DispatchMessage(&msg); } } ``` -- v3: win32u: Don't activate a window that is being deactivated. https://gitlab.winehq.org/wine/wine/-/merge_requests/9398

[PATCH 0/1] MR6385: gdi32: Fix the text's charset error in obtaining from meta dc.
by JiangYi Chen (＠meshine) 09 Dec '25

09 Dec '25

Log: get_dc_attr always failed for meta dc,so GdiGetCodePage always return CP_ACP. And GetTextCharset is similar to this situation. Finally, leading to an error result of text_mbtowc call by ExtTextOutA and an error result of METADC_ExtTextOut.

[PATCH 0/7] MR9579: ntdll: On macOS, transform the main thread into a Wine thread (running a CFRunLoop) on launch.
by Brendan Shanks (＠bshanks) 08 Dec '25

08 Dec '25

Currently, the process's main thread runs `main()` -> `__wine_main()` -> `apple_main_thread()` -> `CFRunLoopRun()`. A run loop source is added that creates the Wine main thread and runs `start_main_thread()`. With this MR, the Wine main thread calls `transform_mac_main_thread()` in `server_init_process()`. That essentially calls `NtCreateThreadEx()`, but instead of creating a new pthread it adds a source to the main thread run loop to run `start_thread()`. This transforms the process main thread into a Wine thread, after that it calls the PE `__wine_mac_run_cfrunloop()` in ntdll. That does a run_mac_cfrunloop Unix call, which just runs `CFRunLoopRun()`. The process main thread is now a Wine thread, but is otherwise still a normal Mac application main thread (including the ability for winemac to transform into a Cocoa application). In theory it might be possible to avoid the initial `CFRunLoopRun()` and have `apple_main_thread()` just spawn the Wine main thread and wait to run `start_thread()`, but the extra `CFRunLoopRun()` on the stack doesn't hurt anything. An exception/crash on the process main thread will be caught like a normal syscall fault, but `__wine_mac_run_cfrunloop()` prints an error and terminates the process. I think this is an improvement over the current behavior, which is a segfault in the signal handler when it tries to access the non-existent TEB that results in the thread hanging and eating 100% CPU. (Arguably it would be even better to unregister the signal handler and re-throw the signal so the user gets a normal macOS crash report with a helpful backtrace, maybe this could be done later.) Besides exception handling, having the main thread be a Wine thread will also allow the full use of Wine logging functions (!9503), and should allow winemac to be simplified (where many AppKit functions must be called from the main thread, and events are delivered to the main thread). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9579
