Review request for KDE Software on Mac OS X and kdelibs. Repository: kdelibs Description ------- I have been experiencing unexpected exits from KDevelop that were not due to any kind of error in the KDevelop code; it was as if someone told the application to exit normally. This happens mostly on OS X, but also sometimes on Linux. I finally traced this to `KGlobal::deref` reaching a zero reference count and invoking `QCoreApplication::quit` when called from one of KDevelop's KJob dtors. There does not appear to be a reference counting mismatch in the code, so the issue might be due to a race condition in KGlobal::ref/deref. This patch introduces thread-safety to KGlobal's reference counting by turning the simple global `static int s_refCount` into a `static QAtomicInt s_refCount`. I consider this an important bug fix regardless of whether it corrects the issue I have with KDevelop. Diffs ----- kdecore/kernel/kglobal.cpp cf003a4 Diff: https://git.reviewboard.kde.org/r/121134/diff/ Testing ------- On OS X 10.6.8 only for now. Thanks, René J.V. Bertin
