[PATCH v8 0/15] MR7516: Server-side thread priorities implementation (Part 3)
by Marc-Aurel Zent (＠mzent) 19 Mar '25

19 Mar '25

This is the continuation of https://gitlab.winehq.org/wine/wine/-/merge_requests/7317. There are a lot of smaller commits (some even no-op renames), because there are some inconsistencies in the codebase currently of what an NT thread priority vs a base thread priority should be (or even constant names being wrong), and I hope that this clears that up a bit. I tried making the commits as atomic as possible. I hope this is fine... There are still a few tiny details missing, like boosting and `KeSetPriorityThread` and friends, which are either stubs or not correctly working as well and have been moved to the next part. I wrote a pretty extensive test for all this too, since pretty much none of how this works is documented (or even misrepresented quite often). For testing, thread priority boosting has been disabled in order to make the behavior on Windows not flaky and dynamic. In fact, on Windows, there is some thread priority boost decay going on after the message has been processed and other mechanisms. The `last` field of `get_thread_info` reply was moved to a flag in order to make space for the thread base priority, since it is already at the limit of 64 bytes. -- v8: ntdll/tests: Add tests for process and thread priority. server, ntdll: Fetch both process priority and base_priority. server: Add process base priority helper. kernelbase: Use ProcessPriorityClass info class in GetPriorityClass. kernelbase: Use correct priority in GetThreadPriority. server, ntdll: Fetch both thread priority and base_priority. server, ntdll: Move last thread information to get_thread_info flags. ntdll: Implement ThreadPriority class in NtSetInformationThread. server: Implement setting thread priority directly. server: Add set_thread_priority helper. server: Rename thread priority to base_priority. server: Rename base_priority to effective_priority in apply_thread_priority. server: Infer process priority class in set_thread_priority. include: Use correct PROCESS_PRIORITY_CLASS_* names. include: Add thread priority constants. https://gitlab.winehq.org/wine/wine/-/merge_requests/7516

[PATCH 0/4] MR7613: winewayland: Clipboard support through core wl_data_device
by Alexandros Frantzis (＠afrantzis) 19 Mar '25

19 Mar '25

This MR adds a fallback path that implements clipboard support using the core protocol (wl_data_device) when wlr-data-control-unstable-v1 is missing. The reasons we want this fallback path, in spite of the extra complexity it introduces, are: 1. Some compositors don't (and likely won't ever) support {wlr,ext}-data-control-unstable-v1. 2. Even compositors that do support {wlr,ext}-data-control-unstable-v1, may not expose it to sandboxed applications. This MR allows Wine to support clipboard operations in such scenarios, in a way that's good enough for many common user clipboard interactions. A more comprehensive discussion of the limitations can be found in !7236. This MR differs from !7236 in that it creates a per-process clipboard thread and window, instead of using the desktop process clipboard thread and manually forwarding messages. Note that the per-process clipboard threads/windows are created only if we fall back to wl_data_device. In the wlr-data-control-unstable-v1 case nothing changes, we still use the desktop process clipboard thread as before. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7613

I was originally looking into that since the reported process base priority was not matching what windows reported and they were set to these values, so I thought they were wrong (which turned out to be not true for a different reason...). In any case, [System Informer](https://systeminformer.sourceforge.io), which is luckily open-source and MIT licensed, displays them like so: ``` static CONST PH_KEY_VALUE_PAIR ProcessPriorityClassTypePairs[] = { SIP(SREF(L"Unknown"), PROCESS_PRIORITY_CLASS_UNKNOWN), SIP(SREF(L"Idle"), PROCESS_PRIORITY_CLASS_IDLE), SIP(SREF(L"Normal"), PROCESS_PRIORITY_CLASS_NORMAL), SIP(SREF(L"High"), PROCESS_PRIORITY_CLASS_HIGH), SIP(SREF(L"Real time"), PROCESS_PRIORITY_CLASS_REALTIME), SIP(SREF(L"Below normal"), PROCESS_PRIORITY_CLASS_BELOW_NORMAL), SIP(SREF(L"Above normal"), PROCESS_PRIORITY_CLASS_ABOVE_NORMAL), }; ``` A quick GitHub code search shows that these are used like so in a wide range of projects, whereas the current Wine naming of `PROCESS_PROCLASS_*` is basically only used by Wine. This also adds the unknown case and starts from `0`, which are both nice-to-haves, and leads me to believe that this is also the original private API naming scheme. If this is still not worth it to do, I can also just drop the commit as well. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7516#note_98393

[PATCH 0/4] MR7612: PDB rewrite #4.
by eric pouech (＠epo) 19 Mar '25

Main target of this serie is to support properly the SYMOPT_LOAD_LINES option flag to dbghelp (turning it off can save some memory). Adding support for 128bit integers in PDB base types, and silencing some more types. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7612

by Louis Lenders (＠xe) 19 Mar '25

Microsoft Edge worked if windows version is set to win8.1 (or win7) but now crashes in current wine due to this unimplemented function. This patch makes it work again in win8.1 mode; (It's still broken in win10 mode, see https://bugs.winehq.org/show_bug.cgi?id=56378 for more info) -- v12: Fix typo https://gitlab.winehq.org/wine/wine/-/merge_requests/7607
