[PATCH v10 0/7] MR9371: kernel32: Implement TH32CS_SNAPMODULE32 support for CreateToolhelp32Snapshot.
by Yuxuan Shui (＠yshui) Dec. 2, 2025

Dec. 2, 2025

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? -- v10: kernel32: Implement TH32CS_SNAPMODULE32 support for CreateToolhelp32Snapshot. kernel32: Use GetCurrentProcess() handle in CreateToolhelp32Snapshot if possible. kernel32/tests: Test CreateToolhelp32Snapshot with TH32CS_SNAPMODULE32. kernel32: Fix CreateToolhelp32Snapshot on old WoW64. include: Add TH32CS_SNAPMODULE32. kernel32/tests: Handle ERROR_BAD_LENGTH from CreateToolhelp32Snapshot. https://gitlab.winehq.org/wine/wine/-/merge_requests/9371

[PATCH v11 0/1] MR5373: shell32: Implement FCIDM_SHVIEW_CREATELINK
by Aric Stewart (＠aricstewart) Dec. 2, 2025

Dec. 2, 2025

Presently the wine file explorer has a create shortcut entry that does nothing. This implements the FCIDM_SHVIEW_CREATELINK command. This is a patch that was first submitted in 2017 and I unfortunately let the revision request fall unimplemented. -- v11: shell32: Implement FCIDM_SHVIEW_CREATELINK https://gitlab.winehq.org/wine/wine/-/merge_requests/5373

[PATCH 0/5] MR9658: PDB reader speedup 1.
by eric pouech (＠epo) Dec. 2, 2025

Dec. 2, 2025

This is a (first) MR about optmizing (new) PDB reader. Context: - game ships with a 1+ GB file and throws an exception at some point in the game, then captures a backtrace with a bunch of dbghelp invocations. - exception is also raised on native but is handled rather quickly (1-2seconds wall time), during what the game completly freezes. Old PDB reader (first context was on Wine 9.x) crashed when reading the PDB file. Serie starts with a fix for that, but it takes ages to load the PDB file. Context moved to Wine 10.x (with new PDB reader). Freeze time is about 7-8s. So this serie and subsequent ones will reduce freeze time (current status is 2.6s). This serie contains: - fix for old PDB reader to avoid crash, - some cleanups in PDB handling (nothing too fancy), - remove the computation of CRC when considering an ELF module, (the only place where this is used if when generating minidump including ELF modules, but the CRC is recomputed anyway). Since the CRC is computed on the whole ELF module image, and depending on number of referenced ELF modules, this can save quite some time (here ~1s). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9658

[PATCH v7 0/5] MR8837: opcservices: Add basic support for reading OPC packages.
by Vibhav Pant (＠vibhavp) Dec. 2, 2025

Dec. 2, 2025

This MR introduces an initial implementation for `ReadPackageFromStream` in order to be able to decompress/read OPC packages, and enumerate their parts. This is required for supporting AppX packages, which themselves are OPC packages as well. As such, the code does not implement support for reading relationships or interleaved archives, as AppX does not support either (`APPX_E_RELATIONSHIPS_NOT_ALLOWED`, `APPX_E_INTERLEAVING_NOT_ALLOWED`). -- v7: opcservices: Implement IOpcPart::GetContentType for opened packages. opcservices: Implement IOpcPart::GetContentStream for opened packages. opcservices: Create IOpcPart objects for ZIP entries in an opened package. https://gitlab.winehq.org/wine/wine/-/merge_requests/8837
