[Bug 59333] VNyan leaks memory (race in __wine_syscall_dispatcher $rsp switching breaks Unity GC)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59333 --- Comment #17 from Hoshino Lina <lina(a)lina.yt> --- Also VNyan does OSC and 4x VMC receivers, so that's another factor of 5, for a total of 5000 chances to hit the race per second. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59333] VNyan leaks memory (race in __wine_syscall_dispatcher $rsp switching breaks Unity GC)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59333 --- Comment #16 from Hoshino Lina <lina(a)lina.yt> --- My understanding is IL2CPP still uses the Mono runtime and bdwgc (it just replaces the managed bytecode with native code) but I could be wrong about how all the pieces fit together in different configurations. See this random IL2CPP build tree I found: https://git.noc.ruhr-uni-bochum.de/krekem24/ANN_Visualisation_in_AR_Builds/… It's not just any Unity app though, it's specifically Unity apps that use managed threads that perform system calls, and it's a tight race that triggers it. uOSC (what VNyan uses) has a managed thread with a blatant poll loop. It's likely other managed libraries also cause the issue. VRChat doesn't use that though, it uses this: https://github.com/stella3d/OscCore While it does use a receive thread, it uses blocking reads, which means the bug can only trigger *each time an OSC message is received*. If you don't use OSC or use it sparingly chances are ~zero. Meanwhile uOSC: https://github.com/hecomi/uOSC/blob/3c80df7ee3ce7c58cb33f5820921a3b192e22c0… ... polls 1000 times per second, no matter what. So I think this still affects ~every Unity app that uses threads, IL2CPP or not. It's just that the race is so tight, that you're only likely to hit it if the Unity app does Very Silly Things Indeed, like uOSC does. To put things into perspective: If you do use OSC with VRChat but only get messages once per frame at ~60Hz, then you're 16 times less likely to hit the bug than on VTube Studio. If it takes 5 hours to hit the bug on average on VTS, it would take 80 hours on average to hit the bug on VRChat. It's all probabilistic, you can still get unlucky and hit it in 5 minutes, but you get the idea. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59364] New: Installation of IE8 breaks starting of xyz.lnk

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59364 Bug ID: 59364 Summary: Installation of IE8 breaks starting of xyz.lnk Product: Wine Version: 11.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ieframe Assignee: wine-bugs(a)list.winehq.org Reporter: andreas.franz(a)arcor.de Distribution: --- I've got a software which uses IEFrame - so I decided to install IE8 via winetricks (without, it crashes unexpected). Sadly, it has some side-effect: wine xyz.lnk only produce an error: Es konnte keine Anwendung gestartet werden, oder es ist keine Anwendung mit der angegebenen Datei verknüpft. ShellExecuteEx fehlgeschlagen: Allgemeiner Fehler. while wine start xyz.lnk works fine. So - all startmenu-entries don't work anymore. Any ideas to fix? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

But installation of IE8 breaks other things (e.g. .lnk don't work as expected). So I made a new wineprefix to isolate. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 57958] Caps lock issue when holding Caps lock with other key and Caps lock state was already on

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=57958 --- Comment #8 from Maotong Zhang <zmtong1988(a)gmail.com> --- (In reply to DanielGGGG from comment #7) > I don't understand what you mean by "uninstalling the input method". No need to test. This two-step state needs to be preserved, otherwise there will be a toggle issue. If you’re only toggling Caps Lock, you can add a hook to check it. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=40435 --- Comment #9 from Esme Povirk <madewokherd(a)gmail.com> --- Seems like SPI_GETDEFAULTINPUTLANG isn't implemented correctly. It's supposed to put an HKL value in the caller's buffer, but it doesn't write anything to the buffer. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
