[PATCH v7 0/3] MR10025: mshtml/msxml3: Add XMLSerializer, embedded XML declaration handling
by Phiality (＠PhialsBasement) June 30, 2026

June 30, 2026

This patchset adds XMLSerializer support and fixes several compatibility issues for Adobe Creative Cloud installer and similar applications. XMLSerializer implementation (mshtml) - Implements the `IXMLSerializer` interface with `serializeToString()` method - Allows JavaScript to serialize DOM elements to XML strings Embedded XML declaration handling (msxml3) - Adds CDATA wrapping for embedded `<?xml?>` declarations inside elements - Windows MSXML tolerates these nested declarations but libxml2 rejects them - The preprocessing step wraps problematic content in CDATA sections before parsing ~~DISPATCH_METHOD|DISPATCH_PROPERTYGET fixes (jscript/mshtml)~~ This was already done !10004 Also added tests for XMLSerializer (empty elements, text nodes, special characters, nested elements, multiple children), embedded XML declaration handling (multiple declarations, deeply nested, encoding attributes, self-closing elements) and DISPATCH_METHOD|DISPATCH_PROPERTYGET behavior in both quirks and standards modes - Filip Bakreski -- v7: mshtml/msxml3/tests: Add tests for XMLSerializer and embedded XML declarations. libs/xml2: Tolerate embedded XML declarations inside elements. mshtml: Add IXMLSerializer implementation. https://gitlab.winehq.org/wine/wine/-/merge_requests/10025

[PATCH v3 0/1] MR10424: services: Cancel overlapped IO after timeout.
by Yuxuan Shui (＠yshui) June 26, 2026

June 26, 2026

Though WaitForSingleObject timed out, the IO operation is still running in the background. After the function process_send_command returns, the OVERLAPPED object referenced by this IO operation becomes invalid. Later, when this IO finally completes, server_select will use invalid stack memory. -- v3: services: Cancel overlapped IO after timeout. https://gitlab.winehq.org/wine/wine/-/merge_requests/10424

[PATCH 0/1] MR9485: ole32: fix property deletion memory leak in IPropertyStorage
by Jiajin Cui (＠jin-king1) June 23, 2026

June 23, 2026

Fixed a memory leak in IPropertyStorage_fnDeleteMultiple when deleting properties by name. Previously, when deleting a property by its name, the code only removed the property from the propid_to_prop dictionary but failed to clean up the bidirectional mapping between property names and IDs in the propid_to_name and name_to_propid dictionaries. This resulted in orphaned dictionary entries and memory leaks. The fix ensures proper cleanup of both dictionaries when deleting properties by name by: 1. Looking up the property name in the name_to_propid dictionary 2. Removing the property from propid_to_prop dictionary 3. Also removing the bidirectional mappings from propid_to_name and name_to_propid dictionaries Signed-off-by: Jiajin Cui <cuijiajin(a)uniontech.com> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9485

[PATCH v2 0/1] MR9480: win32u: Fix broken otmfsType flag generation.
by Patrick Hibbs (＠hibbsncc1701) June 22, 2026

Freetype uses a function to get the licensing flags, FT_Get_FSType_Flags(), and it's non-trivial. (See also: https://freetype.org/freetype2/docs/reference/ft2-information_retrieval.htm…) Use FF's function to get the proper flags, and then set otmfsType based on them.

[PATCH v5 0/2] MR9639: Fix the integration of PowerPoint add-in in MS Office 2016
by Ivan Lyugaev (＠valy) June 19, 2026

June 19, 2026

Encountered an issue with PowerPoint add-in integration. Reviewing the logs revealed the problem was due to the lack of CLSID lookup via the CurVer section and incorrect handling of the PARAMFLAG_NONE flag. A test was conducted in Windows to verify the handling of PARAMFLAG_NONE, PARAMFLAG_FIN, and PARAMFLAG_FOUT. Test class: ``` interface ITest : IDispatch { [id(1)] HRESULT TestMethod(BSTR* value); [id(2)] HRESULT TestMethodOut([out] BSTR* retVal); [id(3)] HRESULT TestMethodIn([in] BSTR* inVal); }; ``` Results in Windows: ``` --------TestMethod-------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethod] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodIn------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodIn] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodOut------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodOut] (null) Invoke returned: 0x00000000 ``` Results in Wine: ``` --------TestMethod-------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethod] (null) Invoke returned: 0x00000000 -------TestMethodIn------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodIn] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodOut------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodOut] (null) ``` Therefore, parameters with the PARAMFLAG_NONE flag are implied to be input parameters in Windows and are handled accordingly as PARAMFLAG_FIN. Added tests for the implemented changes. In the last two tests (their code is provided below), the CLSID is nullified in the guid_from_string function, which is why this test is left with a todo_wine tag. ``` clsid = CLSID_StdFont; hr = CLSIDFromString(L"MyApp.DocumentTest.3", &clsid); todo_wine ok(IsEqualCLSID(&clsid, &CLSID_StdFont), "Unexpected clsid %s.\n", wine_dbgstr_guid(&clsid)); clsid = CLSID_StdFont; hr = CLSIDFromString(L"MyApp.DocumentTest.5", &clsid); todo_wine ok(IsEqualCLSID(&clsid, &CLSID_StdFont), "Unexpected clsid %s.\n", wine_dbgstr_guid(&clsid)); ``` -- v5: combase: Implement CLSID lookup with CurVer fallback oleaut32: Fix parameter value loss in ITypeInfo_Invoke for byref parameters https://gitlab.winehq.org/wine/wine/-/merge_requests/9639

[PATCH 0/23] MR10687: Draft: colorcnv, msvproc, resampledmo: Import and use libswresample and libswscale.
by Rémi Bernon (＠rbernon) June 19, 2026

June 19, 2026

This is an attempt at importing some of FFmpeg code as a PE library, in order to use it to implement audio and video conversion. It removes the need to have the corresponding components available through Gstreamer on the unix side, improves compatibility, as well as performance by a large amount. This is the case in particular for video format conversion. Note that for now it will only benefit pipelines that use these components on the PE side, which is not the majority of use cases right now because we are still doing more than we should on the Gstreamer. I think the idea could perhaps later be extended to cover demuxers (although that could be a bit controversial, but I believe most Linux distributions are distributing them without concerns now), leaving only decoder components to be possibly delegated to the unix side to avoid going into dangerous waters. ``` Measured conversion times for a 4K video frame, average over 1000 calls: (gstreamer) (ffmpeg) I420 -> NV12 2d:0 flip:0 0.232932ms -> 0.122778ms (1.90x) I420 -> NV12 2d:1 flip:0 0.212732ms -> 0.153243ms (1.39x) I420 -> RGB565 2d:0 flip:0 0.415617ms -> 0.153634ms (2.71x) I420 -> RGB24 2d:0 flip:0 0.652448ms -> 0.147694ms (4.42x) I420 -> RGB32 2d:0 flip:0 0.468539ms -> 0.144602ms (3.24x) I420 -> RGB32 2d:0 flip:1 0.442714ms -> 0.176187ms (2.51x) I420 -> RGB32 2d:1 flip:0 0.432901ms -> 0.205248ms (2.11x) I420 -> RGB32 2d:1 flip:1 0.434456ms -> 0.164153ms (2.65x) I420 -> ARGB32 2d:0 flip:0 0.484792ms -> 0.166264ms (2.92x) NV12 -> I420 2d:0 flip:0 0.237323ms -> 0.070567ms (3.36x) NV12 -> I420 2d:1 flip:0 0.233147ms -> 0.085753ms (2.72x) NV12 -> RGB565 2d:0 flip:0 1.073673ms -> 0.628600ms (1.71x) NV12 -> RGB24 2d:0 flip:0 1.310258ms -> 0.737381ms (1.78x) NV12 -> RGB32 2d:0 flip:0 1.365511ms -> 0.810218ms (1.69x) NV12 -> RGB32 2d:0 flip:1 1.213529ms -> 0.832048ms (1.46x) NV12 -> RGB32 2d:1 flip:0 1.185173ms -> 0.821544ms (1.44x) NV12 -> RGB32 2d:1 flip:1 1.051457ms -> 0.837046ms (1.26x) NV12 -> ARGB32 2d:0 flip:0 1.111438ms -> 0.814145ms (1.37x) ``` -- This merge request has too many patches to be relayed via email.
