[PATCH v3 0/4] MR10866: Report FILE_SUPPORTS_OPEN_BY_FILE_ID
by Joel Holdsworth (＠jhol) May 11, 2026

May 11, 2026

Real NTFS volumes on Windows report `FILE_SUPPORTS_OPEN_BY_FILE_ID` in their filesystem attribute flags. MSYS2/Cygwin checks for this flag to decide whether to use `FileRenameInformationEx` with `FILE_RENAME_POSIX_SEMANTICS`. Without it, Cygwin falls back to legacy rename behavior which fails with `STATUS_ACCESS_DENIED` when the target file is still open, breaking operations like gpg's rename of `pubring.gpg` to `pubring.gpg~`. Wine-bug: https://bugs.winehq.org/show_bug.cgi?id=59729 -- v3: mountmgr: Report FILE_SUPPORTS_OPEN_BY_FILE_ID. kernel32/tests: Add test for FILE_SUPPORTS_OPEN_BY_FILE_ID on volume handles. ntdll: Report FILE_SUPPORTS_OPEN_BY_FILE_ID. https://gitlab.winehq.org/wine/wine/-/merge_requests/10866

[PATCH 0/2] MR10852: vbscript/tests: Cover cross-parse name redefinition semantics.
by Francis De Brabandere (＠francisdb) May 11, 2026

May 11, 2026

Native VBScript treats top-level Dim as silently re-declarable across ParseScriptText calls, while Const and Class names cannot be reused once taken, and Sub/Function only conflict with an existing Class of the same name. Pin these rules with cross-parse tests covering each declaration kind paired with each other kind. Wine currently diverges on: - any decl followed by Dim (errs 1041, native accepts); - existing Class followed by Const/Sub/Function (silently allowed, native errs 1041). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10852

[PATCH v2 0/2] MR10843: ntdll: Test unaligned access on ARM64, and fix SIGTRAP handler in some cases on Linux ARM64.
by Brendan Shanks (＠bshanks) May 11, 2026

May 11, 2026

The first commit fixes 569a7553b26dc0a89fb48af5da8442b4f71c42a4 ("ntdll: Use ESR in the ARM64 signal handler when possible."), on Linux it turns out that the ESR can be non-zero but also stale/incorrect. With the unaligned access test added, I was getting failures in later breakpoint tests because the SIGTRAP handler was still using the ESR from the earlier unaligned access fault. The unaligned access test shows a case where Windows differs from Linux/macOS, Wine may need to emulate/handle this in the future. (Unlike Linux/macOS, Windows sets `SCTLR_EL1.nAA` = 1 which results in no alignment fault in some cases) @jacek -- v2: ntdll/tests: Test unaligned access on ARM64. ntdll: Always synthesize ESR in SIGTRAP handler on ARM64 Linux. https://gitlab.winehq.org/wine/wine/-/merge_requests/10843

[PATCH v5 0/3] MR9777: mfplat: Implement mf d3d12 synchronization object.
by Charlotte Pabst (＠CharlottePabst) May 11, 2026

May 11, 2026

I'm also working on tests & implementation for d3d12-backed IMFMediaBuffers and sample allocators, submitting this here to receive some feedback while working on more. Sorry if the tests are too involved, perhaps they could be simplified, but since there is very little documentation on this I had to figure out a lot of minor details using tests. The use case is Fuga Melodies of Steel 3 which uses the UE5 electra decoder plugin. It expects d3d12 support in media foundation (sample allocator, media buffer, sync object). This game doesn't require implementing proper d3d12 video decoding, only that frame data is stored in a IMFMediaBuffer that is backed by a ID3D12Resource. Once finished, this feature would presumably help with other UE5 games that have similar usage patterns as well (All the code for it is in UE5, which is source-available). Other real world examples are limited, but I believe chromium and mesa have some optional code using this feature. MFCreateD3D12SynchronizationObject is (presumably) used by MFCreateDXGISurfaceBuffer to create a synchronization object for the buffer (I already have some tests that query and use the synchronization object from a d3d12-backed mediabuffer, which I will submit together with the other d3d12 buffer tests.) -- v5: mfplat: Implement mf d3d12 synchronization object. mfplat/tests: Add tests for mf d3d12 synchronization object. https://gitlab.winehq.org/wine/wine/-/merge_requests/9777
