Two other observations about adding such a feature, where GC roots are added and removed by sending messages to the daemon:
- Since the daemon would now know exactly when a GC root was removed, this would allow for a time-based garbage collection policy, where a GC only collects things if they have been unreferenced for at least an hour, or a week, or any other period of time. - I believe this would make our GC approach be an example of "partial tracing" as described in Bacon 2004. "A Unified Theory of Garbage Collection", https://www.cs.virginia.edu/~cs415/reading/bacon-garbage.pdf which would be interestingly novel, since they say "We know of no implementation of partial tracing." _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl https://mailman.science.uu.nl/mailman/listinfo/nix-dev
