[PATCH v2 0/6] MR9348: comctl32/imagelist: Pre-multiply rgb by the alpha channel in add_dib_bits for v6.
by Ziqing Hui (＠zhui) 03 Mar '26

03 Mar '26

We used to do this when drawing the image. But our tests show that for v6, the image bitmaps have been alpha pre-multiplied before drawing. So we should do this when adding images. -- v2: comctl32/imagelist: Support adding 32bpp images to a non-32bpp image list for v6. comctl32/imagelist: Do alpha blending when adding 32bpp images to a non-32bpp image list. comctl32/imagelist: Introduce create_dib_section helper. comctl32/imagelist: Introduce image_list_color_flag helper. comctl32/imagelist: Pre-multiply rgb by the alpha channel in add_dib_bits for v6. comctl32/imagelist: Introduce premultiply_alpha_channel helper. https://gitlab.winehq.org/wine/wine/-/merge_requests/9348

by Yongjie Yao (＠yaoyongjie) 02 Mar '26

There will be crashed when connect is null, so we need avoid crash by checking connect value. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7419

[PATCH v4 0/4] MR9973: Draft: conhost: add basic VT control sequence
by Thomas Csovcsity (＠thc13) 02 Mar '26

02 Mar '26

This is a minimal approach to running MC in wineconsole and addresses https://bugs.winehq.org/show_bug.cgi?id=49780. Wineconsole thus supports basic CSI control sequences for: - SGR (Select Graphic Rendition) and - CUP (Cursor Position) ![mc-in-wineconsole-260126](/uploads/36ed70375b31955fa44dc477e832242c/mc-in-wineconsole-260126.gif){width=900 height=507} **TODO:** - [x] check for ENABLE_VIRTUAL_TERMINAL_PROCESSING - [x] bug states that SetConsoleMode does not return error code and therefore applications fail to handle it correctly - [ ] rewrite, if that is the way to go i will do that, to use newer API. This would allow more colors than ANSI colors only - [ ] test shared: several programs attached to the same console -- v4: conhost: add basic CUP color handling conhost: improve basic SGR color handling conhost: add basic SGR color handling conhost: add basic VT control sequence parsing https://gitlab.winehq.org/wine/wine/-/merge_requests/9973

[PATCH v3 0/1] MR9943: msiexec: Fix escaping quoted arguments passed from Shell.
by Yaroslav Osipov (＠mcm) 19 Feb '26

19 Feb '26

Properties with spaces passed to `msiexec` from shells like Bash may result in re-escaping the string. This results in wrong new quote position and so in MSI error `ERROR_INVALID_COMMAND_LINE`. This patch moves the quote back to its legal position. Step-by-step behavior after fixes in commit `14b718b69bb8d` (linked with Wine bug https://bugs.winehq.org/show_bug.cgi?id=57024) 1. Shell input: wine msiexec /i some.msi INSTALLDIR="C:\\Path with spaces\\data" 2. Shell args parser may remove double quote escaping: args\[3\] == "some.msi" args\[4\] == "INSTALLDIR=C:\\Path with spaces\\data" 3. `GetCommandLineW()` returns string with quote moved to the start: "msiexec ... some.msi "INSTALLDIR=C:\\Path with spaces\\data"" 4. Then MSI parser truncates beginning of the string up to character '=', leading to unbalanced quotes in result value: C:\\Path with spaces\\data" 5. MSI fails with error `ERROR_INVALID_COMMAND_LINE` (1639). Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57024 Tests in bug 57024 are fine to reproduce the behavior, but note that `system()` and `execvp()` function passes their input on without extra parsing (without item 2 in the fail trace algorithm above). An example of such test: ``` execlp("msiexec", "msiexec", "/i", msi_path, "/qn", "\"MY_PROPERTY=foo bar\"", NULL); ``` -- v3: msiexec: Fix escaping quoted arguments passed from Shell. https://gitlab.winehq.org/wine/wine/-/merge_requests/9943

[PATCH v5 0/2] MR9639: Fix the integration of PowerPoint add-in in MS Office 2016
by Ivan Lyugaev (＠valy) 18 Feb '26

18 Feb '26

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
