[PATCH v4 0/1] MR8466: ntdll: Also restore rbp before calling user mode callback.
by Yuxuan Shui (＠yshui) July 5, 2025

July 5, 2025

If wine dlls are built with frame pointers enabled, the frame pointer will be used during unwinding. If we don't restore frame pointer before calling the user mode callback, then later when the unwinder encounters the user mode callback frame, it will set the frame pointer to something unexpected (depends on what it was during `call_user_mode_callback`). Then for the subsequent frame it adjusts the stack pointer based on the frame pointer, thus derailing the unwinding process. -- v4: ntdll: Also restore rbp before calling user mode callback. https://gitlab.winehq.org/wine/wine/-/merge_requests/8466

[PATCH 0/10] MR8505: mfsrcsnk, winegstreamer: Implement thinning.
by Charlotte Pabst (＠CharlottePabst) July 4, 2025

July 4, 2025

Follow-up to !8184. This also adds a bunch of helpers for writing media source tests (without involving the mf session) in mfsrcsnk, these could be helpful for more tests of this kind in the future. I'm somewhat unsure as to why we haven't done tests for source behavior so far: while those are plugins, applications rely on a bunch of things in the builtin sources that microsoft provides. Since this affects both mfsrcsnk and winegstreamer sources, tests should be run both with `HKCU\\Software\\Wine\\MediaFoundation\\DisableGstByteStreamHandler` enabled and disabled. Due to this I figured it'd make sense to implement everything first and then remove the test todo_wine's and the statements rejecting the thin parameter in a single commit ("Allow thinning"). Perhaps this could be solved more nicely by setting the registry key in the tests themselves? I'm unsure if that is something we do in tests, generally. `MEStreamThinMode` events need to be emitted between the last sample using the outdated thinning parameter and the first sample using the updated thinning parameter. The winegstreamer implementation for this turned out a bit complex, if there is a simpler way to do this please let me know. Regarding winegstreamer, note that buffers need to be intercepted before the decoder because decoders often discard `GST_BUFFER_FLAG_DELTA_UNIT` flags (which is already annoying in itself - it causes all samples to be marked as `MFSampleExtension_CleanPoint`, this should potentially be worked around in the future). But even besides that, intercepting before the decoder is the "proper" implementation, since the point of thinning is increasing decoding speed by skipping delta frames, tho there are some games that rely on the semantics as well. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8505

Wine's implementation should do the same. Hello Vibhav, You only spoke of `LPSYSTEM_POWER_STATUS.ACLineStatus` used in `powermgnt.GetSystemPowerStatus`. Am I to assume `SYSTEM_BATTERY_STATE.AcOnLine` in `system.fill_battery_state` holds a value reflecting the system's actual state? Asking so I'm sure where to enforce that logic. Thanks. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8460#note_108840

[PATCH 0/1] MR8487: configure: Use SSE for floating point math on i386.
by Jacek Caban (＠jacek) July 4, 2025

July 4, 2025

The main motivation here is to unify the build configuration. This primarily impacts GCC MinGW, since Clang already defaults to using SSE. Additionally, downstream projects like Proton and CrossOver already use `-mfpmath=sse`. This does slightly change the compatibility requirements, we now assume SSE support. That’s unlikely to be an issue today, but for those who need it, the behavior can still be overridden via `CROSSCFLAGS`. If needed, we could also add a `--disable-sse` configure option to make this easier to control. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8487

[PATCH v2 0/4] MR8500: Some improvements to widl.
by eric pouech (＠epo) July 4, 2025

This MR improves widl with : - fixes a segfault when inheriting from an incomplete interface (prints an error message instead), - supports (for C++) inheriting from interfaces which are declared after the declaration of the derived interface. -- v2: include: Remove duplicated declarations in .idl files. tools/widl: Ensure inherited interface is declared before using it. tools/widl: Remove unneeded condition. tools/widl: Fix segfault when inheriting from an incomplete interface. https://gitlab.winehq.org/wine/wine/-/merge_requests/8500
