[Bug 45369] New: Under certain (unknown) conditions, winedbg.exe continually spawns explorer.exe sub-processes until it is killed
https://bugs.winehq.org/show_bug.cgi?id=45369 Bug ID: 45369 Summary: Under certain (unknown) conditions, winedbg.exe continually spawns explorer.exe sub-processes until it is killed Product: Wine-staging Version: 3.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: roman(a)hargrave.info CC: leslie_alistair(a)hotmail.com, z.figura12(a)gmail.com Distribution: --- Created attachment 61679 --> https://bugs.winehq.org/attachment.cgi?id=61679 A portion of wine console output collected after the event I'd like to open with a note that I am not submitting this on wine-devel, as I the only application that has been able to cause these crashes will not run well enough to reliably reproduce the error without DXVK, and in turn wine-staging (as far as I am aware, DXVK continues to require a patch in the staging patchset that has not been mainlined - correct me if i am wrong). The application which has been causing problems is Grand Theft Auto V, though specifically Rock Star Social Club (I can't be terribly certain - but the issue tends to crop up when social club is brought in to the question). Glancing at the crash info in the terminal (winedbg is actually not even visible yet as it is too preoccupied with explorer), this is the result of an exception thrown within libcef.dll, which judging by the name and the platform which it is used by, is chromium embedded framework - a common offender. Knowing this, i'll just avoid the social club in-game if at all possible, but what's concerning is the outcome. Something about the manner in which it has gone about crashing causes some _very_ eratic behaviour in winedbg. For some reason, `explorer.exe /desktop` is invoked as a child process of winedbg and then fails to start. Another instance of explorer with the same parameters is then started by the child, as well as some concurrent instances (I think - when you have so many process running that your PIDs roll over it start to get hard to track who started who) - effectively an explorer fork bomb, though it dies off fast enough if you get to winedbg and kill it or its parent. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=45369 --- Comment #2 from Zebediah Figura <z.figura12(a)gmail.com> --- This would make sense if explorer.exe crashes; it'll try to start the winedbg crash dialogbut the latter will involve creating a window and thus starting another instance of explorer.exe. In that case creating the registry key HKCU\Software\Wine\WineDbg and setting the value ShowCrashDialog to 0 should work around the problem. It would be good to fix this, of course.

https://bugs.winehq.org/show_bug.cgi?id=45369 --- Comment #7 from roman(a)hargrave.info <roman(a)hargrave.info> --- OK, so due to the complexity of steam and steam games, I'm going to have to lower a couple of the channel verbosity levels. The sheer overhead from logging is going to make it take extraordinarily long to actually get the chance to launch the only application (GTA V) which is known to bring about the issue, and then it will only crash at some arbitrary point during gameplay (due to a DXVK stub) which will be heavily affected by the log levels. If you can let me know what you can work with as far as channel levels, lmk, but I'm going to run it with info-level instead of trace-level -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=45369 --- Comment #8 from Zebediah Figura <z.figura12(a)gmail.com> --- I wouldn't expect just those channels to introduce a lot of overhead. Are you sure you don't have something like +relay on? I don't need dxvk logs, so there's no need to use anything other than the default log level there. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=45369 --- Comment #9 from roman(a)hargrave.info <roman(a)hargrave.info> --- DXVK logging cannot be turned off. I'm not using any other channels - specifically, it was run with -all,+seh,+win,+explorer,+module. Specifically, `win` introduced so much logging traffic that the steam updater was downloading an update at about 10KB/s -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=45369 --- Comment #11 from Zebediah Figura <z.figura12(a)gmail.com> --- Well, I wouldn't grab logs while Steam is updating itself if possible.

Well, I wouldn't grab logs while Steam is updating itself if possible.
Still, if it's that infeasible, I guess just +seh,+module,+explorer might be enough to rootcause the problem.
The updater runs and may or may not unpack files every startup. Regardless, the fact that it was doing what it was to the updater means that I would have to clock about three hours of gameplay (measured at full speed) at roughly ten seconds per frame, which would be totally not feasible. Still, nonetheless, I have attached a log with -all,+seh:trace,+win:warn,+explorer:info,+module:warn (or something, the ensuing process leak actually killed my disk IO in less than three seconds due to the kernel attempting to swap 16Gb of resident programs at high priority, I don't have the exact invocation since my shell actually failed to write a history file as a result) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=45369 --- Comment #14 from Zebediah Figura <z.figura12(a)gmail.com> --- Unfortunately this isn't really helpful as it is, partly due to the lack of any useful channels and partly because apparently kernel32 wipes the WINEDEBUG variable when launching the debugger anyway. However, it does seem my initial guess was incorrect—the new explorer.exe instances seems to be launched by explorer itself and not by winedbg. But without any useful traces I can't determine why that happens. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
