[PATCH 0/1] MR10400: vbscript: Map DISP_E_DIVBYZERO to VBScript error 11.
by Francis De Brabandere (＠francisdb) March 20, 2026

March 20, 2026

Add the missing DISP_E_DIVBYZERO mapping in map_vbs_exception() so that division by zero errors report Err.Number = 11 with the correct description "Division by zero", matching native behavior.

Re: [PATCH v31 0/1] MR10192: kernelbase: Handle extended length path prefix in GetLongPathNameW
by Akihiro Sagawa (＠sgwaki) March 20, 2026

March 20, 2026

It looks like a test case was dropped somewhere during your Git operations. To make the intent clearer, could you add a todo_wine-style test in addition to the fix. Also, please use a module name prefix in your commit subject. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10192#note_132984

[PATCH v2 0/1] MR10326: Draft: mmdevapi: Avoid copying more memory than reserved in validate_fmt (ASan).
by Bernhard Übelacker March 20, 2026

March 20, 2026

The function `validate_fmt` may receive a pointer which got just reserved memory for the `WAVEFORMATEX`. Unfortunately the assignment `fmt2 = *fmt` always copies the size of `WAVEFORMATEXTENSIBLE`.

[PATCH 0/1] MR10395: crypt32: Don't access CERT_CHAIN_ENGINE_CONFIG::dwExclusiveFlags without checking size.
by Yuxuan Shui (＠yshui) March 20, 2026

March 20, 2026

Found by ASan. Example in test `crypt32:chain`, `testCreateCertChainEngine`. Pointer to a `CERT_CHAIN_ENGINE_CONFIG_NO_EXCLUSIVE_ROOT` is passed to `CertCreateCertificateChainEngine`. Accessing `dwExclusiveFlags` unconditionally is out-of-bound. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10395

Re: [PATCH v2 0/14] MR10349: opengl32: Implement wglGetProcAddress on the client side.
by Jacek Caban (＠jacek) March 20, 2026

March 20, 2026

> we simply cannot know whether they are supposed to add new commands or token or not. Specs for most of them are available, so we know they don't add new commands. They are just not a part of the official registry. > I also didn't see GL_EXT_demote_to_helper_invocation among them. It seems to be Mesa specific, and looks wrong to me. The extension is actually a shader extension, and I don't think it's supposed to be in the GL extension string, but rather included in GLSL #extension? It is part of the extension strings exposed by Mesa. In any case, we could filter it if there is an actual benefit, but I do not see why we would need to. What exactly looks wrong to you? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10349#note_132976

Yes, it's about those two extensions mostly. I could maybe disable others, but why? They are well handled by make_opengl. I also don't see how being similar to other extensions changes anything. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10349#note_132975

[PATCH v2 0/1] MR10396: Draft: vbscript: Implement IActiveScriptError::GetSourceLineText.
by Francis De Brabandere (＠francisdb) March 20, 2026

March 20, 2026

Extract the error source line in report_script_error() and store it in VBScriptError so that GetSourceLineText can return it. Also fix a memory leak in VBScriptError_Release where EXCEPINFO BSTRs were not freed. -- v2: vbscript: Implement IActiveScriptError::GetSourceLineText. https://gitlab.winehq.org/wine/wine/-/merge_requests/10396

[PATCH v5 0/1] MR10393: Draft: vbscript: Check named item dispatch for Dim variable names.
by Francis De Brabandere (＠francisdb) March 20, 2026

March 20, 2026

When declaring variables with Dim in a visible named item context, check the named item's IDispatch for each variable name via GetIDsOfNames. This matches Windows VBScript behavior where Dim probes the host object before creating the variable. -- v5: vbscript: Check named item dispatch for Dim variable names. https://gitlab.winehq.org/wine/wine/-/merge_requests/10393
