[PATCH v42 0/1] MR10192: Draft: kernelbase: Handle extended length path prefix in GetLongPathNameW

``` Support the \\?\ prefix by skipping it during path resolution while preserving it in the output. Added specific handling for extended UNC paths (\\?\UNC\) to mirror standard UNC behavior, ensuring these paths are treated as network shares and not local devices. Some paths that use the extended length path were filtered out as UNC paths - but not all of them are UNC. There can be UNC path that use extended length path but not all extended length paths are UNC paths. ``` Signed-off-by: Vishnunithyasoundhar S svishnunithyasoundhar(a)gmail.com -- v42: kernelbase: Handle extended length path prefix in GetLongPathNameW https://gitlab.winehq.org/wine/wine/-/merge_requests/10192

[PATCH v2 0/1] MR10541: vbscript: Fast-path assign_value for simple non-refcounted types.
by Francis De Brabandere (＠francisdb) April 1, 2026

April 1, 2026

Skip VariantCopyInd and VariantClear when both source and destination are simple scalar types (VT_I2, VT_I4, VT_R8, VT_BOOL, VT_EMPTY, etc.) that require no memory management. A direct struct assignment suffices for these types. Benchmarks (10M iterations, measured in isolation on top of master): - Do-While loop: 824 -> 472 ms (1.75×) - For + assignment: 324 -> 265 ms (1.22×) - Dict.Items iteration: 683 -> 324 ms (2.1×) - If-Else branching: 726 -> 644 ms (1.13×) Every variable assignment in the interpreter benefits. The fast path eliminates two cross-DLL calls to oleaut32 (VariantCopyInd + VariantClear) for each assignment of simple scalar types (VT_I2, VT_I4, VT_R8, VT_BOOL, etc.), replacing them with a single struct copy. -- v2: vbscript: Fast-path assign_value for simple non-refcounted types. https://gitlab.winehq.org/wine/wine/-/merge_requests/10541

Skip VariantCopyInd and VariantClear when both source and destination are simple scalar types (VT_I2, VT_I4, VT_R8, VT_BOOL, VT_EMPTY, etc.) that require no memory management. A direct struct assignment suffices for these types. This avoids two cross-DLL calls into oleaut32 for every integer or float variable assignment. The fast path covers VT_EMPTY through VT_UINT (19 types) excluding VT_BSTR, VT_DISPATCH, VT_UNKNOWN, VT_VARIANT, and VT_RECORD which need refcounting or deep copy. Types with VT_BYREF or VT_ARRAY flags always take the slow path. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10541

[PATCH v2 0/1] MR10454: vbscript: Return DISP_E_TYPEMISMATCH when indexing non-array variables.
by Francis De Brabandere (＠francisdb) April 1, 2026

April 1, 2026

Indexing or assigning to a non-array, non-dispatch variable (e.g. Integer, String, Boolean, Empty, Null, Double, Date) with variant_call() returned E_NOTIMPL. Windows returns DISP_E_TYPEMISMATCH (error 13). -- v2: vbscript: Return DISP_E_TYPEMISMATCH when indexing non-array variables. https://gitlab.winehq.org/wine/wine/-/merge_requests/10454

When Option Explicit is set and a For loop uses an undefined variable, throw error 500 (Variable is undefined) with proper description instead of just returning E_FAIL.

[PATCH v4 0/2] MR7696: mf: Specify the multithreaded queue for timer callbacks.
by Conor McCarthy (＠cmccarthy) April 1, 2026

April 1, 2026

This fixes audio dropout in the game Birdcage. I made a test which shows Windows delivering samples from two different threads, which implies a multithreaded queue. The test is probably not suitable for upstream because multithreaded queues respond to load, and a system with sufficient performance may use one thread. -- v4: mf: Specify the multithreaded queue for sample grabber timer callbacks. mf: Specify the multithreaded queue for presentation clock callbacks. https://gitlab.winehq.org/wine/wine/-/merge_requests/7696

[PATCH 0/2] MR10540: build: Fix warnings with recent gcc/glibc versions
by Katharina Bogad (＠hackathi) April 1, 2026

April 1, 2026

Recent (at least >= 15.2) GCC changes enabled -Wdiscarded-qualifier by default. Fixing these warnings allows for building with -Werror again. Also, recent GCC versions switched to use C23 by default. This causes glibc to define wcschr, wcsrchr and wcspbrk as macros in their version of wchar.h. Redefining those also leads to a warning, which gets converted to an error with -Werror. The second commit in this MR detects this case and `#undefs` the macros. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10540
