[PATCH v12 0/1] MR10192: kernelbase: Handle \\?\ prefix in GetLongPathNameW
by Vishnunithyasoundhar S (＠svishnunithyasoundhar) Feb. 27, 2026

Feb. 27, 2026

The current implementation of GetLongPathNameW triggers a FIXME and returns the original path when it encounters a UNC prefix. While true network UNC paths remain unimplemented, this change allows extended-length local paths (starting with \\?\) to be resolved by stripping the prefix and processing the underlying local path. This fixes issues where applications (such as xalia) passing absolute paths with the extended-length prefix would fail to receive a normalized or resolved long path. ``` 881.036:00d4:00d8:fixme:file:GetLongPathNameW UNC pathname L"\\\\?\\Z:\\home\\vishnunithyasoundhars\\.steam\\debian-installation\\compatibilitytools.d\\debug_build\\files\\share\\wine/../xalia/xalia.exe" ``` Tested: After change with added debug log ``` 22272.558:00d4:00d8:fixme:file:GetLongPathNameW DEBUG: Success!

This needs to be rebased instead of merged, as Wine uses a linear history. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10193#note_130750

[PATCH v2 0/6] MR10209: kernelbase/loader.c: Include rudimentary support for multilanguage resource inclusion.
by Craig Schulstad (＠NoDakker) Feb. 27, 2026

Feb. 27, 2026

For programs that rely on language specific data for resources such as menus and text, attempt to search for and associated "mui" file. For example, if program "myapp.exe" is executed and resources are not found, and the user's language ID is "en-US", search for file "en-US/myapp.exe.mui", and if found, utilize that file for the source of resource data. -- v2: kernelbase/loader.c: Add rudimentary support for multiplanguage resource inclusion. https://gitlab.winehq.org/wine/wine/-/merge_requests/10209
