This should be fixed in current svn, particularly revision r1070014

Comment 5 Milian Wolff 2010-01-07 20:37:57 UTC

Reopening since jmho found a way to reproduce this crash (though now with a zero-pointer dereference - in a line without any pointer dereferences....)

I tried to debug this but can't find something useful so far with gdb. *it is valid, it points to a KUrl with a proper QUrl (but the KUrl d-pointer is 0 - could that be the issue?)...

Will try again with valgrind now.

To reproduce: Close all files and open projects. Then open a project -> the background parser should kick in and eventually leads to a crash...

Comment 6 Milian Wolff 2010-01-07 20:50:38 UTC

Here's the valgrind result... It crashes on this it seems:

            ParseJob* job = language->languageSupport()->createParseJob(url);

The strange part: both language _and_ language->languageSupport() are checked above so it's some kind of race condition I think, will investigate further...

Comment 7 Milian Wolff 2010-01-07 21:17:36 UTC

So, finally hunted it down:

The problem is that the CMakeManager (which is also the LanguageSupport) gets deleted:

Hence the d-pointer in the Language (which does _not_ get deleted!) is invalid and leads to a crash. I don't know why it gets deleted but my guess is because it's also a BuildManager. Probably would be good if each would be it's own class.

Comment 8 Andreas Pakulat 2010-01-07 22:35:10 UTC

Thanks Milian for hunting this down.

I can see already at least one problem in Core::cleanup() in shell. The order of cleanup is not the same as the order of initialization. Can you test wether it helps to cleanup the language controller before the plugincontroller? The plugin controller will be unloading all plugins, including any language plugins and in fact the cmake plugin will already be unloaded when the last cmake project is closed in the projectcontroller.

The backtrace indicates that the plugin is deleted via a DeferredDelete event, which is usually created by deleteLater(), which in turn is used in the plugincontroller.

Comment 9 Milian Wolff 2010-01-12 15:56:14 UTC

Hm I tried that out but it didn't help. And I mean this is logical: It doesn't crash when you close KDevelop, it crashes when the build-manager gets unloaded. Core::cleanup is not touched in this crash. Aren't the build-manager's / project-managers unloaded when there is no project open which uses them?

Right, my analysis was a bit wrong. So what needs to be done is that the languagecontroller needs to keep track of plugins being unloaded and if one of them is a language plugin it also needs to drop any references to this plugin, including any Language objects.

I don't think you can split the cmake manager without having to parse each cmake file twice (which is horrible given the current performance of the parser).

Imo not only the lang controller would need to keep track, any controller would have to do that... Probably the best would be to refcount the IProject, that should solve this magically, no? Could we not simply use QSharedPointer for that purpose? You know, I'm still learning these things :)

I don't see how refcounting IProject would help here.(In reply to comment #11)

Any controller that keeps a private list of pointers to plugins, yes. But that is by design, they're actually not supposed to do so or live with the fact that plugins can be removed behind their back and work with that.

I don't see how refcounting IProject would help here. The only thing that could help would be to use QWeakPointer in the language controller's list and then check any object fetched from that list before accessing it.

Comment 13 Milian Wolff 2010-01-13 20:19:18 UTC

Hm let me rephrase to make my intention clearer:

If we'd use a QSharedPointer and let it decide when to delete the plugin and when not, i.e. no manual qDeleteAll / deleteLater in any controllers, we should be on the safe side, no? And I picked IProject just because it's the base class, I dunno what would happen if I have:

class foobar : IProject, Iface1, Iface2 {};

class Controller1 { QList<QSharedPointer<IFace1> >; }
class Controller2 { QList<QSharedPointer<IFace2> >; }

The adresses should be the same for IFace1 and IFace2 afaik, but does QSharedPointer differentiate between the class type? I think so, but this is pure gutfeeling. If one would just store QSharedPointer<IProject> it should be on the safe side.

Oh and to restress my point about deleting: Imo the deletion is simply wrong, just because one controller says "ok, this iface is not needed anymore", doesn't say that the given Object implementing this iface is not implementing other ifaces, hence must _not_ be deleted (just like with the CmakeManager).

If we use QSharedPointer it would be deleted when it's not required anymore, no?

IProject is not a base class for any plugins. You probably mean IProjectFileManager.

And no, thats not a solution, at least not without a complete redesign. Right now the Plugincontroller is the core instance that loads and unloads plugins. If we'd use QSharedPointer then you'd have plugin instances around that are not tracked anymore by the plugincontroller. So you can easily get into the situation that something asks the plugincontroller to load plugin X which is actually not yet unloaded/deleted because some other object still has a reference to it. Now you get two instances of the same plugin loaded twice, this is a major change in our plugin system and breaks the promise to plugin authors that only 1 plugin instance will ever be running. This can easily lead to race-conditions when these instances are trying to write some data (in some global object or just config files).

Comment 15 Milian Wolff 2010-01-13 21:51:03 UTC

Zomg, here I am blabbling about IProject all the time while I mean _IPlugin_ of course ;-)

But your point is valid I think, I'll have to do some more debugging to see who exactly triggers the deletion and maybe I can come up with a workaround.
