    remove default: section (to catch missing impl of a future value in the enum)



kio/kio/clipboardupdater_p.h

    I'm confused. If the user presses Undo, the whole copy/move operation is undone, not just one URL out of many URLs, right?
    
    So I don't see why OverwriteContent doesn't work too, for the undo case?
    
    You cut three files A,B,C from dir1, and paste them into dir2. OverwriteContent updates the clipboard to dir2/{A,B,C}. If you then undo, the 3 files are moved from dir2 back to dir1, and  therefore OverwriteContent can be used to update the clipboard from dir2/{A,B,C} to dir1/{A,B,C}. What am I missing?
    
    Sounds to me like UpdateContent is there for the purpose of the other cases you mention in the description (e.g. #134960), but that's not tested yet.

However, addressing these issues require a careful consideration of how to do it since delete/rename/move operations can be done outside of KDE's control. Do we simply fix the KIO jobs to handle this or do we address it the KDirWatch level so we catch all the scenarios? Probably the latter. Anyhow, that can wait until for the 134960 fix.
