[PATCH 0/2] MR10927: vbscript: Mark class member fixed-size arrays as FADF_FIXEDSIZE
by Francis De Brabandere (＠francisdb) May 18, 2026

May 18, 2026

When a class member is declared with explicit bounds (Private mArr(N) or Public mArr(N)) the SAFEARRAY created at instance construction was missing FADF_FIXEDSIZE, so interp_redim's fixed-size guard silently accepted a later ReDim from a method body. Set the flag (and FADF_STATIC) to match interp_dim's handling of local fixed-size arrays, so ReDim raises err 10 like native. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10927

[PATCH 0/2] MR10928: vbscript: Reject re-Dim of an existing global array with err 13.
by Francis De Brabandere (＠francisdb) May 18, 2026

May 18, 2026

A separate ExecuteGlobal can re-encounter a name that was already Dim'd as an array (dynamic or fixed) in an earlier compile unit. Native raises err 13 (Type mismatch) for this case. Wine silently accepted the dynamic form and leaked E_FAIL as a raw HRESULT for the fixed form. Check for an existing array variant at the start of interp_dim's FUNC_GLOBAL branch and raise VBSE_TYPE_MISMATCH consistently. Re-Dim'ing a previously scalar Dim continues to work. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10928

[PATCH 0/1] MR10930: wininet: Fix a memory leak in HTTP_DoAuthorization.
by Alex Henrie (＠alexhenrie) May 18, 2026

The leak was identified by Cursor, which is a mix of LLM models. I wrote the fix myself. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10930

[PATCH 0/1] MR10933: kernelbase: Add null check for str in OutputDebugStringW
by Matthias Gorzellik (＠gotzl) May 18, 2026

May 18, 2026

The following code crashes wine but seems to be OK in Windows: ``` #include <windows.h> int main() { OutputDebugStringW(NULL); return 0; } ``` The MR aligns behavior of `OutputDebugStringW` to Windows by adding a null check and bailing out of `OutputDebugStringW`. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10933

[PATCH 0/2] MR10934: kernel32/tests: Add tests for ReplaceFileW.
by Kun Yang (＠yangkun) May 18, 2026

May 18, 2026

I ported an application using wine. But I found that it lauched successfully only the first time. I solved this bug. The application calls ReplaceFileW to move a file to a directory. The file and the directory have the same name. Wine just move the direcory to a file. When the application launced the second time, it can not create the directory because there is a file owns the same name. So it can not launch. I think this is a bug. I made a test on Windows, when replaced is a directory, Windows just do nothing and return FALSE. The last error is ERROR_ACCESS_DENIED. But in Wine, it does the replace operation and return TRUE. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10934

[PATCH v2 0/1] MR10921: Draft: vbscript: Fast-path interp_add and var_cmp for pure-integer operands.
by Francis De Brabandere (＠francisdb) May 18, 2026

May 18, 2026

For-loop counters and conditional comparisons hit VarAdd/VarCmp every iteration with trivial I2/I4 operands, but the full VARIANT conversion pipeline (VariantChangeType, locale grab/free in ucrtbase) dominates the cost. Short-circuit at the call site in interp.c when both operands are pure VT_I2/VT_I4: compare directly, or add via LONGLONG with native promotion (I2+I2 -> I4 on overflow, I4+I4 -> R8 on overflow). Alternative to !10528 Keeps the optimisation scoped to vbscript c ### Compared to !10528 (oleaut32 version) | Scenario | master | !10528 (oleaut32) | this MR (vbscript) | |---|---:|---:|---:| | Empty For (10M) | 2678 | 364 (7.4x) | **320 (8.2x)** | | If-condition in loop | 3678 | 718 (5.1x) | **632 (5.8x)** | | Local var reads | 1247 | 403 (3.1x) | **382 (3.25x)** | | Class prop read | 289 | 164 (1.8x) | 171 (1.73x) | | For R8 counter | 2910 | 2764 | 2625 | | String concat | 70 | 70 | 70 |allers rather than adding branches to oleaut32 generic VarAdd/VarCmp. -- v2: vbscript: Fast-path interp_add and var_cmp for pure-integer operands. https://gitlab.winehq.org/wine/wine/-/merge_requests/10921
