Re: [PATCH v2 0/2] MR4108: Improve DMI tables under Linux.
by Gabriel Ivăncescu Oct. 20, 2023

Yeah, but this isn't necessarily about not trusting Windows apps, i.e. malice or malware, but rather that they can't be designed around it (since they assume Windows environment), so they would have privacy issues without even wanting to. At the very least maybe use `sd_id128_get_machine_app_specific` with a unique app ID for Wine? Simple and still better than nothing. Otherwise, it would probably have to be done per-prefix (registry?), since two processes in the same prefix might want the same ID. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4108#note_49432

[PATCH v6 0/1] MR4049: ntdll: Implement thread-ID alerts using kqueue()/kevent()
by Marc-Aurel Zent (＠marzent) Oct. 20, 2023

Oct. 20, 2023

This allows *BSDs to also have a fast path similar to futexes for thread-ID alerts. Also a kevent with `EV_CLEAR` and `NOTE_TRIGGER` maps perfectly to the thread alertable state, fixing the issue of the current mach-semaphore implementation not correctly waiting in the test case below: ``` NtAlertThreadByThreadId((HANDLE)GetCurrentThreadId()); NtAlertThreadByThreadId((HANDLE)GetCurrentThreadId()); NtWaitForAlertByThreadId(NULL, NULL); NtWaitForAlertByThreadId(NULL, NULL); ``` I took the liberty to remove this mach semaphore implementation, since all versions of OSX have supported kqueue(). -- v6: ntdll: Implement thread-ID alerts using kqueue/kevent. https://gitlab.winehq.org/wine/wine/-/merge_requests/4049

[PATCH v10 0/4] MR1088: ntdll: Avoid calling pthread_exit on thread exit.
by Rémi Bernon Oct. 20, 2023

Oct. 20, 2023

Using a dedicated exit jmpbuf and removing the need for assembly routines. When Wine handles an exception in unix code, we return to user mode by jumping to the last syscall frame. This can leave some pthread cancel cleanups registered, in the pthread internal linked list, and at the same time later overwrite the stack frame they were registered for. In the same way, jumping to the exit frame on thread exit or abort, can also leave some cleanup handlers registered for invalid stack frames. Depending on the implementation, calling pthread_exit will cause all the registered pthread cleanup handlers to be called, possibly jumping back to now overwritten stack frames and causing segmentation faults. Exiting a pthread normally, by returning from its procedure, or calling exit(0) for the main thread doesn't run pthread_exit and doesn't call cleanup handlers, avoiding that situation. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52213 ### Additional note: For robustness, we should probably try to execute these cleanup handlers when unwinding the stack frames, as we would otherwise leave pthread objects in a potential problematic state (like a mutex locked, etc). It is however hard to do so when the handlers are registered from some C code: pthread C implementation is done by calling some internal pthread functions to register the handlers, and they aren't registered as standard unwind handlers. Only pthread_cancel and pthread_exit can unwind and call / unregister the C handlers, but interrupting that procedure, for instance calling setjmp / longjmp from withing our own handler isn't supported. >From C++ code, pthread cleanup handlers are registered through C++ class constructors / destructors, and it would then be possible to partially unwind and call them at the same time. -- v10: ntdll: Remove now unnecessary arch-specific exit frame. ntdll: Avoid calling pthread_exit from abort_thread. ntdll: Avoid calling abort_thread from the signal stack. ntdll: Use is_inside_syscall more consistently. https://gitlab.winehq.org/wine/wine/-/merge_requests/1088

[PATCH v15 0/12] MR3938: winegstreamer: Implement CLSID_CMpegVideoCodec
by Alfred Agrell (＠Alcaro) Oct. 20, 2023

Oct. 20, 2023

Resolves https://bugs.winehq.org/show_bug.cgi?id=9127 . (Some of the named programs in that issue may require additional currently-missing functionality, I didn't check; but if so, that's separate issues.) Tested with - winetest on Windows 7 - winetest on Windows 10 - winetest in Wine, of course - microkiri https://bugs.winehq.org/show_bug.cgi?id=9127#c102 - Wagamama High Spec Trial Edition https://wagahigh.com/download_trial.php#normal (ダウンロード means download) - Ninki Seiyuu no Tsukurikata Trial https://archive.org/details/sayou_trial (WMV files in microkiri and Wagamama don't work, but that's separate issues. Also, they need the LC_ALL=ja_JP env, or they throw various goofy errors.) -- v15: quartz/tests: Add tests for CLSID_CMpegVideoCodec. quartz/tests: Add tests for new CLSID_MPEG1Splitter functionality. winegstreamer: Improve and clean up some debug logs. winegstreamer: Include the framerate when converting video format to GstCaps. winegstreamer: Don't read format from unparsed MPEG audio. winegstreamer: Seek to end of stream instead of to stream duration. winegstreamer: Implement a little more of IAMStreamSelect in CLSID_MPEG1Splitter. winegstreamer: Implement CLSID_CMpegVideoCodec. winegstreamer: Add program stream and video output support to CLSID_MPEG1Splitter. https://gitlab.winehq.org/wine/wine/-/merge_requests/3938
