Orphaned cache keys #116

Closed mkutyba closed 7 years ago

mkutyba commented 7 years ago

Hello,

I have deleted some keys using "Delete Keys" dialog. But only tags was deleted and keys remain untouched. So now they are orphans and I have no idea how to delete them. The method _collectGarbage doesn't help, orphaned keys remain.

I don't know anything about this Delete Keys dialog but deleting a key should never result in a tag being deleted because when deleting specific keys the cleaning up of empty tags is left up to garbage collection. However, I recommend using the lua option to avoid things like race conditions that can result in corrupted metadata.
