Sergei Trofimovich d58453f72e gc: don't visit implicit referrers on garbage collection ... Before the change garbage collector was not considering `.drv` and outputs as alive even if configuration says otherwise. As a result `nix store gc --dry-run` could visit (and parse) `.drv` files multiple times (worst case it's quadratic). It happens because `alive` set was populating only runtime closure without regard for actual configuration. The change fixes it. Benchmark: my system has about 139MB, 40K `.drv` files. Performance before the change: $ time nix store gc --dry-run real 4m22,148s Performance after the change: $ time nix store gc --dry-run real 0m14,178s		2022-03-17 18:47:29 +00:00
