[PATCH v3 0/2] MR9369: wininet: Return correct errors and put handle into invalid state when seeking beyond end of file.
by Torge Matthies (＠tmatthies) 02 Dec '25

02 Dec '25

When `InternetSetFilePointer` is used to seek and then read beyond the size of the remote file, the initial read will fail with `ERROR_NOACCESS` and put the handle into an invalid state such that `InternetSetFilePointer`, `InternetReadFile`, and `InternetQueryDataAvailable` will return errors from then on. -- v3: wininet: Return correct errors and put handle into invalid state when seeking beyond end of file. wininet/tests: Add tests for seeking beyond end of file. https://gitlab.winehq.org/wine/wine/-/merge_requests/9369

by pan hui (＠panhui) 02 Dec '25

After creating the Select Topic window, it was first displayed and then hidden, causing the user to see a black window appear and disappear, affecting their experience; There is no need to set WS_VISSIBLE to display the Select Topic window first. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9649

[PATCH v7 0/7] MR9371: kernel32: Implement TH32CS_SNAPMODULE32 support for CreateToolhelp32Snapshot.
by Yuxuan Shui (＠yshui) 02 Dec '25

02 Dec '25

Intention is to use `CreateToolhelp32Snapshot` in `dbghelp.dll: EnumerateLoadedModulesW64`. Right now we can't because `CreateToolhelp32Snapshot` can't capture 32bit modules in wow64 processes, which is needed to support `SYMOPT_INCLUDE_32BIT_MODULES`. The advantage of using `CreateToolhelp32Snapshot` in mainly performance. Right now `EnumerateLoadedModulesW64` is `O(n^2)`, because of each module it calls `GetModuleInformation` which is itself `O(n)` w.r.t. number of modules. Whereas with `CreateToolhelp32Snapshot` there is no need for `GetModuleInformation`, thus reduce the complexity to just `O(n)`. * * * P.S. I am also uncomfortable with the amount of similar code between `CreateToolhelp32Snapshot` and `EnumProcessModulesEx`. Can something be done here? -- v7: kernel32: Implement TH32CS_SNAPMODULE32 support for CreateToolhelp32Snapshot. kernel32: Use GetCurrentProcess() handle in CreateToolhelp32Snapshot if possible. kernel32/tests: Test CreateToolhelp32Snapshot with TH32CS_SNAPMODULE32. https://gitlab.winehq.org/wine/wine/-/merge_requests/9371

It's been a long time. I think it was "云视讯ViLin", but I'm not 100% sure. Also, it's possible that the application has been updated since then, which might be why the issue can no longer be reproduced.

[PATCH v7 0/2] MR9632: sxs: avoid uninitialised len_name length
by Hans Chen (＠hans.chen) 02 Dec '25

02 Dec '25

The `redirect_data->clrdata_len` [is unset in /dlls/ntdll/actctx.c#L4411-4412](https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/ntdll/actctx.c?ref_type=heads#L4411-4412) when using registration-free COM in C# NET code. Program.cs ```C# //... Guid guid = Guid.Parse("COM clsid"); Type type = Type.GetTypeFromCLSID(guid, true); var instance = Activator.CreateInstance(type)); //... ``` App.manifest ```xml <assembly> <file name="ExampleCOM.dll"> <comClass description="ExampleCOM" progid="ExampleCOM" clsid="{COM clsid}" threadingModel="Free"/> </file> </assembly> ``` The above C# code gets this error on its second line. ```Shell System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ``` This is because `len_name` is uninitialized when calling `memcpy(ret_strings, ptr_name, len_name);` in `SxsLookupClrGuid`, which is fixed in this MR. -- v7: change xml format https://gitlab.winehq.org/wine/wine/-/merge_requests/9632
