Hey! I was wondering if kbuildsycoca's global code still has a reason to exist.
The way I read the code a local kbuildsycoca would only reuse the global sycoca iff languages, prefixes and signatures are a match. But prefixes are not ever the same in any "default" or even reasonable scenario. Specifically, prefixes are essentially QStandardPaths::GenericDataLocation paths and those include at least one user-specific directory on every single platform documented for QSP. On linuxy systems this is even a very important path as (e.g.) application desktop files edited by kmenuedit are stored in XDG_DATA_HOME, so not including that would break overrides or custom software installs. Additionally bundle software such as flatpak can do user-specific software installation which means it also injects paths into XDG_DATA_DIRS. So, as far as I can tell the prefix constraint is always false and with that the global cache is not ever used. That leads me to the questions: Do we still need the global cache feature at all? How would we even go about repairing this? We can't just ignore XDG_DATA_HOME. Thoughts? HS
