General question. delete order and references


#1

Because I was not careful enough, I’ve already run a few times in some destruction order issues. Typically :

  • an AudioThumbnailCache getting deleted before an AudioThumbnail that is using it.
  • the DirectoryContentsList used by FileListComponent

The bad thing is that sometime you won’t notice the bug before quite some time…

I guess they could be ReferenceCounted (?), but otherwise is there any other smart way that I could (should) use for now to avoid that to happen again (except by being more careful when coding : ) ?


#2

Be super-careful. Add member variables in initialisation order. Treat the order of variables like the order of code.
