[PATCH v23 0/6] MR6166: separate env for windows applications (WINENV) from env for wine processes (NIXENV)
by Alois Schloegl (＠schloegl) 09 Nov '25

Because WINENV is limited (32767 bytes), and HOSTENV can be much larger, a whitelisting approach is used to keep WINENV as small as possible. Currently, only the following envvars are propagated from the host env to WINENV WINEPATH, WINEPWD, WINEHOME, WINETEMP, WINETMP, WINEQT_, WINEVK_, WINEXDG_SESSION_TYPE Moreover, the NIXENV (env for running wine processes - not applications) on the host system is not produced from WINENV anymore, but the global ENV is propagated to all wine processes and threads. This might be an alternative approach to MR!5231, MR!6140, bug #56941 and should provide a more deterministic behaviour of wine, because unrelated envvars do have no influence on the env for running windows applications. Initial tests (winemine, notepad, cmd, etc) seem to run fine, but some envvars might need additional consideration. XVDK_* was mentioned, WINE*, MESA_*, VK_*, QT_*, LIBGL_* are other suspects. Moreover, this is my first merge request, so your feedback is highly appreciated. -- v23: ntdll: main_envp has been replaced by environ ntdll: remove is_dynamic_env_var(...) because it is not needed anymore ntdll: remove unused vars ntdll: remove dead code ntdll: conversion from HOSTENV to WINENV is now using whitelisting instead of blacklisting of envvars currently only envvars "WINE"<special_var> (as defined in is_special_env_var() ) are whitelisted. ntdll: separate env for windows applications (WINENV) from env for wine processes (NIXENV) WINENV is typically limited to 32767 WCHAR, the host environment where wine processes are running can be much larger. Keeping the two envs separate enables a more granula handling of envvars. (see also MR!5231, MR!6140, bug #56941) https://gitlab.winehq.org/wine/wine/-/merge_requests/6166

[PATCH 0/1] MR7901: ntdll: Treat XDG_DATA_DIRS as special env variable.
by Louis Lenders (＠xe) 09 Nov '25

09 Nov '25

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=49987 GTK apps seem to use this env var to find path to schemas, like Meld: https://download.gnome.org/binaries/win32/meld/3.22/Meld-3.22.2-mingw.msi which doesn't start at all without this patch. More info in https://bugs.winehq.org/show_bug.cgi?id=49987. v2: add WINEXDG_DATA_DIRS and use that in winemenubuilder. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7901

[PATCH v2 0/1] MR5890: winex11.drv: Fix a possible desktop window message queue hang.
by Zhiyi Zhang (＠zhiyi) 07 Nov '25

07 Nov '25

After an X11 event handler queues messages to another thread, TRUE should be returned and eventually propagated to X11DRV_ProcessEvents(). When FALSE is always returned in xrandr14_device_change_handler(), a possible hang can happen for the desktop message queue as follows: 1. The explorer.exe calls GetMessageW() -> NtUserGetMessage() -> wait_objects() -> wait_message(). 2. In wait_message(), user_driver->pProcessEvents() gets called in the desktop window thread to handle RRNotify events and calls xrandr14_device_change_handler() -> display_mode_changed(FALSE) -> send_message(get_desktop_window(), WM_DISPLAYCHANGE, ...) -> desktop_window_proc() -> send_message_timeout() -> send_client_message() -> process_message() -> broadcast_message() -> send_message_timeout() -> send_client_message() -> process_message() -> send_inter_thread_message() -> wait_message_reply() -> a server set_queue_mask() with skip_wait being 1 -> wake_mask and changed_mask are set to 0. 3. In wait_message(), user_driver->pProcessEvents() returns FALSE from xrandr14_device_change_handler(). So wait_message() continues to call NtWaitForMultipleObjects(). 4. Now NtWaitForMultipleObjects() hangs for INFINITE timeout because wake_mask and changed_mask for the message queue are set to 0 so the thread is not woke up. The hang is sensitive to message ordering and only happens in this specific case so it's hard to reproduce with tests. I believe some of the past test timeouts on TestBots can be attributed to this bug. -- v2: winex11.drv: Fix a possible desktop window message queue hang. https://gitlab.winehq.org/wine/wine/-/merge_requests/5890

[PATCH v4 0/9] MR8812: winegstreamer: Support 2D sample buffer.
by Conor McCarthy (＠cmccarthy) 03 Nov '25

03 Nov '25

Performance issues can occur when a video output sample has a 2D buffer, because winegstreamer currently outputs only to a linear buffer, which must then be copied into the 2D buffer. Worse, a linear lock of the 2D buffer requires the current contents to be copied to a linear buffer, even when we intend to overwrite it, because MF linear buffers do not support write-only locking. -- v4: mf/tests: Test H.264 sink media type height alignment. winegstreamer: Support 2D sample buffer. mf: Test color convert 2D buffers. mf: Test WMV decoder 2D buffers. mf: Test H.264 decoder 2D buffers. mf: Test sample copier 2D buffers. mfplat/tests: Test NV12 negative stride in MFCreateMediaBufferFromMediaType(). mf/tests: Remove todo for an H.264 decoder test. mf/tests: Stop checking samples at the end of the expected array. https://gitlab.winehq.org/wine/wine/-/merge_requests/8812

[PATCH v2 0/1] MR7410: test-linux32: Disable broken tests that are already released broken
by Damien Zammit (＠zamaudio) 28 Oct '25

28 Oct '25

This should allow the CI to fully pass on this merge request. If it does, master branch could have CI tests enabled to ensure any actual broken test caused by a merge request is visible just by the CI status, and master can also reflect the passing status.
