[PATCH v75 0/2] MR10295: Fix ImageGetDigestStream
by Trent Waddington (＠trent.waddington) May 18, 2026

May 18, 2026

ImageGetDigestStream is used to hash the "important" parts of PE files. After rigorous experimentation we discovered these changes were sufficient to get identical hashes (and thereby signatures) on Windows and Wine. -- v75: imagehlp: Fix ImageGetDigestStream. https://gitlab.winehq.org/wine/wine/-/merge_requests/10295

by Rémi Bernon (＠rbernon) May 18, 2026

This may happen if HDC is from a Pbuffer, and context was created separately. Let's not be restrictive if host GL allows it. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=59555 -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10914

[PATCH v5 0/1] MR9038: Draft: msi: implement MsiProvideAssembly[AW]()
by Ratchanan Srirattanamet (＠ratchanan.sr) May 17, 2026

May 17, 2026

TODO: - make awstring version of MsiProvideComponent() and use that. - Actually implement MsiProvideAssemblyA() using the above. - Write conformance test? Dependency: - Have ACTION_PublishAssemblies() record feature (https://gitlab.winehq.org/wine/wine/-/merge_requests/9037) - Have MsiEnumFeatures() fixed. Currently it seems to just look for features at the wrong place and thus is useless for this purpose.

[PATCH v27 0/6] MR10515: Draft: vbscript: Bind local variables, class properties, and loop variables at compile time.
by Francis De Brabandere (＠francisdb) May 17, 2026

May 17, 2026

Resolve identifiers to direct indices during compilation instead of doing runtime `wcsicmp` string scans in `lookup_identifier()`. This adds new opcodes that access local variables, function arguments, class properties, and loop variables by index, eliminating the linear string comparison overhead for the most common cases. **New opcodes:** - `OP_local` / `OP_assign_local` / `OP_set_local` - read/write local vars and args by index - `OP_local_prop` / `OP_assign_local_prop` / `OP_set_local_prop` - read/write class properties by index - `OP_step_local` / `OP_incc_local` - For-loop step/increment with indexed counter - `OP_enumnext_local` - For-Each iteration with indexed loop variable This mirrors jscript's `OP_local` / `bind_local()` optimization (`dlls/jscript/compile.c`) and addresses the FIXME in `lookup_identifier()` noting that class property access should be bound at compile time. Names that cannot be resolved at compile time (globals in Execute/ExecuteGlobal code, dynamic vars, host objects) continue to use the existing string-based path. The last commit also adds a fast path for SAFEARRAY iteration that bypasses the `IEnumVARIANT` COM vtable dispatch and copies elements directly from the array data, eliminating one intermediate `VariantCopy` per iteration. ### Local variable / argument / class property access (1M iterations, 10 reads per iteration) | Benchmark | Windows (VM) | Wine master | Wine (7 commits) | **Speedup** | vs Windows | |-----------|-------------|-------------|-------------------|---------|------------| | Local vars | 156 ms | 413 ms | 234 ms | **1.8x** | 1.5x slower | | Arguments | 171 ms | 357 ms | 231 ms | **1.5x** | 1.4x slower | | Class props | 265 ms | 393 ms | 226 ms | **1.7x** | 0.9x (faster!) | ### For-loop variants (10M iterations) | Benchmark | Windows (VM) | Wine master | Wine (7 commits) | **Speedup** | vs Windows | |-----------|-------------|-------------|-------------------|---------|------------| | Empty For | 117 ms | 370 ms | 270 ms | **1.4x** | 2.3x slower | | For + assign | 203 ms | 613 ms | 430 ms | **1.4x** | 2.1x slower | | Do-While manual | 437 ms | 646 ms | 513 ms | **1.3x** | 1.2x slower | | For Step 2 | 62 ms | 370 ms | 271 ms | **1.4x** | 4.4x slower | | Nested For | 125 ms | 387 ms | 268 ms | **1.4x** | 2.1x slower | | For local Sub | 109 ms | 294 ms | 251 ms | **1.2x** | 2.3x slower | | For R8 counter | 203 ms | 2,812 ms | 2,529 ms | **1.1x** | 12x slower | | For-Each array | 7 ms | 286 ms | 62 ms | **4.6x** | 8.9x slower | The remaining 4-13x gap vs Windows in For-loops is from `VarAdd`/`VarCmp` going through full `VariantChangeTypeEx` machinery (including locale alloc/free per call). A separate MR ([!10528](https://gitlab.winehq.org/wine/wine/-/merge_requests/10529)) adds I2/I4 fast paths in oleaut32 that bring integer loops within 1.2-1.9x of Windows when combined with this branch. -- v27: vbscript: Bind class properties at compile time. vbscript: Bind For-loop variables at compile time. vbscript: Factor out do_for_step and do_incc from interp_step and interp_incc. vbscript: Bind local variable assignments at compile time. vbscript: Factor out assign_local_var from assign_ident. vbscript: Bind local variables and arguments at compile time. https://gitlab.winehq.org/wine/wine/-/merge_requests/10515

[PATCH v7 0/1] MR10541: vbscript: Fast-path assign_value for simple non-refcounted types.
by Francis De Brabandere (＠francisdb) May 17, 2026

May 17, 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. -- v7: vbscript: Fast-path assign_value for simple non-refcounted types. https://gitlab.winehq.org/wine/wine/-/merge_requests/10541

[PATCH 0/1] MR10926: ntdll,msv1_0: Add fallback paths for systems without posix_spawn().
by Twaik Yont (＠twaik) May 17, 2026

May 17, 2026

This adds fallback implementations for posix_spawn() usage in ntdll and msv1_0. Older Android versions do not provide posix_spawn() or posix_spawnp(). The affected code paths only need simple helper process startup and only distinguish success from failure, so this keeps the existing posix_spawn() implementation where available and uses vfork() with execv()/execvp() otherwise. The ntdll loader path preserves the existing execv-style behavior for a fully built path. The msv1_0 ntlm_auth path preserves the posix_spawnp-style PATH lookup by using execvp() in the fallback. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10926
