Git commit a7117e430454f8e39b1279695ff83bf73e1eb9ed by Martin Flöser.
Committed on 05/11/2017 at 09:25.
Pushed by graesslin into branch 'Plasma/5.11'.

Don't use the global KConfig object on the OpenGL freeze detection thread

Summary:
This is meant to address Bug 372114. The problem here is that the KConfig
object (and its derivatives), that the freeze detection thread needs to
record the freeze, are not thread safe. When it happens that the main
thread is in fact not frozen, it is possible that the two stomp on each
other's KConfig object.

The solution applied here is to use the KSharedConfig::openConfig
function, which is thread safe, on the freeze detection thread. As was
mentioned by Martin Flöser in the discussion, the thread needs to obey
the name of the main config file of KWin, which can change in the future.

As a secondary issue, this patch also turns off KCrash reporting for
aborts due to a freeze being detected. IMO it is not very user friendly
to still show a crash report to the user, even after this bug is fixed,
for the deliberate SIGABRT. Maybe a less intrusive notification could be
used to tell the user why effects are suddenly disabled?

I've been using kwin with this change for several weeks now and it makes
the restarts of kwin due to freezes unobtrusive. However, most (I would
say almost all) of these freezes are actually instances where the system
 is being slow after eg. screen resolution is changed.

Good! If KSharedConfig::openConfig(kwinApp()->config()->name()) is acceptable
in principle, so be it. I'll just test it a bit more.

About the phabricator: is there some tutorial or manual about how to use it? I
have to say I'm not that familiar with KDE dev process.

KSharedConfig::openConfig introduces a slight other problem: internally KWin
uses the kwinApp()->config() to make it possible to have config not use kwinrc,
but different config files (that is extensively used by e.g. autotests). The
idea behind it is that we can swap out the config at runtime for different form
factors (tablet -> notebook -> tablet). While that's not yet fully implemented,
the config part is prepared. If we use openConfig again we don't know whether
it's the same or not.

If KSharedConfig::openConfig(kwinApp()->config()->name()) works as well, that
might be a solution. Anyway if you have a patch, please put it on
phabricator.kde.org and use #KWin as review group.

--- Comment #29 from Jiri Palecek  ---
Well the patch does actually help, because while the KConfig instances are not
thread-safe, KSharedConfig::openConfig _is_ (see
https://api.kde.org/frameworks/kconfig/html/classKSharedConfig.html). Access to
the file is locked on the file level. Dreaming about making KConfig thread-safe
(or almost any other Qt or KDE classes for that matter) is an utopia, and
totally unnecessary in this case.

As for the freezes in OpenGL, I don't deny them. However, the current method of
detecting them gives an awful lot of false detections, and maybe something
could be done about that.

The freeze check was introduced because we were experiencing freezes in the
OpenGL driver. That's why it was introduced and implemented like that and has
to stay like that to prevent freezes also in future.

You are right that the problem is KConfig which is not thread safe. But I fear
your patch won't help. The proper change would be to make KConfig thread safe
or to guard the write access in KWin. Latter is not yet done as it's actually
difficult to know where in KWin we have concurrent situations. A possibility
might be to use a dedicated different config file which is only used here.

... oh and mind you, the patch actually changes the situation from an
unexpected  crash on SIGSEGV to a SIGABRT anticipated by the code, so DrKonqi
gets triggered either way. This sould be thought over as well IMHO.

Hello

the problem here seems to be the fact that KConfig instances are *totally* not
thread safe, and the freeze protection thread uses the same one as the main
thread. When they stomp over each other, this crash ensues. I'll attach a
proposed patch to use a different KConfig instance.

On a deeper note, is that freeze check really necessary, safe and effective? I
would say 99%+ of times the freeze alarm goes off, it is actually the system
thrashing after startup/closing a big application (like a game), when all of
the other applications are resizing their windows/repainting and not really an
opengl driver freeze (of these duplicates, only bugs 372078, 373485 seem to be
genuinely related to the graphics. Any thoughts on that?

--- Comment #12 from Max  ---
Created attachment 103593
  --> https://bugs.kde.org/attachment.cgi?id=103593&action=edit
New crash information added by DrKonqi

kwin_x11 (5.8.5) using Qt 5.6.2

- What I was doing when the application crashed:

I just rebooted the computer and logged in. It looks like it crashed when KDE
was loading.
