Probably needs a separate ticket, unless someone confirms all those TaskManager::TasksModel crashes have the same cause. *** Bug 381317 has been marked as a duplicate of this bug. *** *** Bug 381950 has been marked as a duplicate of this bug. *** *** This bug has been marked as a duplicate of bug 381974 *** According to bug 381317 comment #11, this is the master bug for all TaskManager model crashes. Reopening, because it is not resolved. Eike, bug 381974 comment #3 has some good investigation for bug 381317 (originating from KWindowSystem::windowRemoved). Thanks, very good indeed. *** Bug 382564 has been marked as a duplicate of this bug. *** *** Bug 382665 has been marked as a duplicate of this bug. *** Plasma crashes when I have many open windows and I try to sort them The Backtrace have the parameter QSortFilterProxyModelPrivate::updateChildrenMapping Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Committed on 07/08/2017 at 10:24. Pushed by hein into branch 'master'. Fix QSortFilterProxyModelPrivate::updateChildrenMapping crash in libtaskmanager Summary: TaskGroupingProxyModel uses a simple QVector<QVector<int>> populated with source model row indices to represent the task group tree. To implement QAbstractItemModel::parent(), its implementation of index() encodes row indices of the top-level vector into the internal ids of child item model indices. This allows parent() to produce the parent model index by simply decoding the parent row from the passed-in child index and call index() with that row. Top-level row indices shift up and down as the list of top-level items changes, invalidating those internal ids. QModelIndex is not meant to be stored, and the proxy model does take care of updating any persis- tent model indexes with new ids, so this should be fine. However, where it falls apart is that as internal ids are invalidated, a QSortFilterProxyModel on top of this proxy (i.e. TasksModel) may end up with multiple indexes with identical internal ids in its mappings, causing it to mess up its mappings as it uses them (e.g. taking things from them). This causes the often-reported crash/assert there. The fix is to refactor index()/parent() not to rely on row indices as internal ids, but instead use pointers to internal data structures instead. This patch achieves this by changing the map to QVector<QVector<int> *>. This screams fugly, but the alternative would basically just be to create some wrapper struct to hide the fugly appeareance a little, which I don't think is worth it. On the flip side, it saves a QVector::replace() call as a multable vector iterator can work directly on a vector without making a copy, and it's now no longer necessary to manually update the persistent model indices beyond what endRemoveRows() does implicitly.
